    Tumours metastatic to the heart (cardiac metastases) are among the least known and highly debated issues in oncology, and few systematic studies are devoted to this topic. Although primary cardiac tumours are extremely uncommon (various postmortem studies report rates between 0.001% and 0.28%), secondary tumours are not, and at least in theory, the heart can be metastasised by any malignant neoplasm able to spread to distant sites. In general, cardiac metastases are considered to be rare; however, when sought for, the incidence seems to be not as low as expected, ranging from 2.3% and 18.3%. Although no malignant tumours are known that diffuse preferentially to the heart, some do involve the heart more often than others—for example, melanoma and mediastinal primary tumours. This paper attempts to review the pathophysiology of cardiac metastatic disease, epidemiology and clinical presentation of cardiac metastases, and pathological characterisation of the lesions.

    An 81-year-old woman with a history of malignant melanoma who presented with dyspnea and fatigue was found to have metastases to the stomach detected on endoscopy. Primary cutaneous malignant melanoma with gastric metastases is a rare occurrence, and it is often not detected until autopsy because of its non-specific manifestations. PMID:27609722

    Radiotherapy for brain metastases has become more multifaceted. Indeed, with the improvement of the patient's life expectancy, side effects must be undeniably avoided and the retreatments or multiple treatments are common. The cognitive side effects should be warned and the most modern techniques of radiation therapy are used regularly to reach this goal. The new classifications of patients with brain metastases help guiding treatment more appropriately. Stereotactic radiotherapy has supplanted whole brain radiation therapy both for patients with metastases in place and for those who underwent surgery. Hippocampus protection is possible with intensity-modulated radiotherapy. Its relevance in terms of cognitive functioning should be more clearly demonstrated but the requirement, for using it, is increasingly strong. While addressing patients in palliative phase, the treatment of brain metastases is one of the localisations where technical thinking is the most challenging. PMID:27523410

    The most frequent intracranial brain tumours are brain metastases. All types of cancer can develop brain metastases but two thirds of brain metastases occurring in adult patients are secondary to one of these three cancers: lung cancer, breast cancer and melanoma. In accordance with these data, this review is focusing on the epidemiology of these three types of cancer. We report here the incidence, risk factors, median time of brain metastases occurrence after diagnosis of the primary cancer, prognosis and median survival for these three types of cancer. We also discuss the clinical implications of these data. The second part of this review is focusing on the Graded Prognostic Assessment scores in all types of primary cancer with brain metastases, how they can be applied in clinical research for a better stratification of patients, and to some extent in clinical practice to guide decisions for personalized treatments. These scores provide a better understanding of the different profiles of clinical evolution that can be observed amongst patients suffering from brain metastases according to the type of primary cancer. We highlighted the most remarkable and useful clinical implications of these data. PMID:25636729

    Surgical excision of brain metastases has been well evaluated in unique metastases. Two randomized phase III trial have shown that combined with adjuvant whole brain radiotherapy, it significantly improves overall survival. However, even in the presence of multiple brain metastases, surgery may be useful. Also, even in lesions amenable to radiosurgery, surgical resection is preferred when tumors displayed cystic or necrotic aspect with important edema or when located in highly eloquent areas or cortico-subcortically. Furthermore, surgery may have a diagnostic role, in the absence of histological documentation of the primary disease, to rule out a differential diagnosis (brain abscess, lymphoma, primary tumor of the central nervous system or radionecrosis). Finally, the biological documentation of brain metastatic disease might be useful in situations where a specific targeted therapy can be proposed. Selection of patients who will really benefit from surgery should take into account three factors, clinical and functional status of the patient, systemic disease status and characteristics of intracranial metastases. Given the improved overall survival of cancer patients partially due to the advent of effective targeted therapies on systemic disease, a renewed interest has been given to the local treatment of brain metastases. Surgical resection currently represents a valuable tool in the armamentarium of brain metastases but has also become a diagnostic and decision tool that can affect therapeutic strategies in these patients.

    The majority of patients with metastatic melanoma will develop brain metastases, which are the most common cause of death. Until recently, local therapies (e. g., neurosurgery, radiotherapy) were the only options for brain metastases; however, effective systemic treatment options are now available. Upon suspicion of brain metastases, diagnostic staging with brain MRI and a neurological investigation are indicated. Prognostic factors such as number of cerebral metastases and symptoms, serum lactate dehydrogenase and S‑100 levels, extracerebral metastases, and ECOG status are considered during therapeutic planning. Treatment planning and therapeutic interventions should be based on an interdisciplinary and multimodal approach. Established treatments for singular brain metastases are neurosurgical resection and stereotactic radiotherapy, which can prolong survival. In patients with asymptomatic BRAF V600E-mutant brain metastases, the BRAF inhibitors dabrafenib, vemurafenib, and immunotherapy with ipilimumab are used. In the case of multiple symptomatic brain metastases, palliative whole-brain radiotherapy is used for treatment, although it has failed to show an overall survival benefit. Increased intracranial pressure and epileptic seizures are addressed with corticosteroids and anticonvulsants. Current clinical studies for melanoma patients with brain metastases are investigating new treatment options such as PD-1 antibodies, combined ipilimumab and nivolumab, combined BRAF inhibitors and MEK inhibitors, and stereotactic radiation in combination with immunotherapy or targeted therapy.

    Medulloblastoma is the most common childhood malignant tumor of central nervous system, but it may also occur in adults. It presents high invasive growth with spreading of tumor cells into the leptomeningeal space along the neuroaxis early in the course of the disease. Extraneural metastases are rare but frequently lethal, occurring only in 1 to 5% of patients, and are related, in the most of cases, to the presence of ventriculoperitoneal shunt. Here we characterize the clinical profile of five cases of medulloblastoma with systemic spreading of tumor cells, also comparing them to cases already described in the literature. PMID:21625760

    The diagnosis and management of CRLM is complex and requires a multidisciplinary team approach for optimal outcomes. Over the past several decades, the 5-year survival following resection of CRLM has increased and the criteria for resection have broadened substantially. Even patients with multiple, bilateral CRLM, previously thought unresectable, may now be candidates for resection. Two-stage hepatectomy, repeat curative-intent hepatectomy, and even selected resection of extrahepatic metastases have further increased the number of patients who may be treated with curative intent. Multiple liver-directed therapies exist to treat unresectable, incurable patients with adequate survival benefit and morbidity rates. PMID:22312501

    Boney metastasis may lead to terrible suffering from debilitating pain. The most likely malignancies that spread to bone are prostate, breast, and lung. Painful osseous metastases are typically associated with multiple episodes of breakthrough pain which may occur with activities of daily living, weight bearing, lifting, coughing, and sneezing. Almost half of these breakthrough pain episodes are rapid in onset and short in duration and 44% of episodes are unpredictable. Treatment strategies include: analgesic approaches with "triple opioid therapy", bisphosphonates, chemotherapeutic agents, hormonal therapy, interventional and surgical approaches, steroids, radiation (external beam radiation, radiopharmaceuticals), ablative techniques (radiofrequency ablation, cryoablation), and intrathecal analgesics.

    Benign metastasizing leiomyoma (BML) is a rare and poorly characterized disease affecting primarily premenopausal women. Asymptomatic patients are often diagnosed incidentally by radiographs or other lung-imaging procedures performed for other indications, and the diagnosis is eventually confirmed by biopsy. Patients with BML are usually treated pharmacologically with antiestrogen therapies or surgically with oophorectomy or hysterectomy. Antiestrogen therapy is typically efficacious and, in general, most patients have a favorable prognosis. Asymptomatic patients with a confirmed diagnosis of BML, may be followed conservatively without treatment. PMID:27514603

    A primary goal of cancer research is an increased understanding of the molecular mechanisms mediating the process of cancer metastasis. Analyses of colon cancer cells (the seeds) and the microenvironment (the soil) have increased our understanding of the biologic mechanisms mediating metastasis formation. Insight into the molecular mechanisms regulating the pathobiology of colon cancer metastasis, as well as a better understanding of the interaction between the metastatic cell and the host environment (including the vasculature), should provide a foundation for new therapeutic approaches. To the clinician, it is readily apparent that by the time metastases form, most steps in the metastatic cascade have completed. Therefore, therapy to down-regulate or interrupt the last stages of metastasis, proliferation and angiogenesis as well as mechanisms to disrupt cell survival signals seems the most promising areas of investigation.

    The skeleton is the most common site to be affected by advanced breast, prostatic, lung, kidney, thyroid and other solid tumors (in addition to myeloma multiplex). Bone metastases cause significant morbidity with nearly always fatal outcome. Over 600 000 new patients diagnosed in the developed countries yearly. On average every 4-6 months patients suffer from series of severe skeletal complications such as pathologic fractures, spinal cord compression, hypercalcemic events, etc., besides the permanent pain. Local external beam radiotherapy, systemic radioisotope-, endocrine-, and chemotherapy, oral and i.v. bisphosphonates and recently s.c. denosumab are the mainstays of treatment, in addition to pain-killers and other usual "classical" interventions. The modern treatments singificantly reduce the probability of skeletal complications and improve the patients' quality of life and, sometimes, they extend the survival as well. The authors briefly summarize the available treatment options. PMID:24486845

    Metastases to the breast are uncommon, wtih about 250 cases reported from clinical and autopsy series. The mammographic findings in 16 new cases revealed a spectrum of changes that included solitary of multiple lesions, well demarcated or poorly marginated masses, and diffuse involvement of skin or parenchyma or both. Diffuse disease was seen more frequently in this series (4/16), at times simulating inflammatory breast cancer. Although diagnosis of a primary malignancy usually preceded detection of the breast lesion, 40% (6/16) had no history of malignancy. Prognosis remains poor; however, it was improved in the lymphoma-leukemia group due to improved immunotherapeutic and chemotherapeutic regimes. The clinical, radiologic, and pathologic features are discussed. Some of the lesions encountered can be confused with a primary breast malignancy or a benign lesion, necessitating prompt and accurate biopsy to preclude unnecessary major surgery and to improve survival in cancers amenable to current therapy.

    This paper will focus on knowledge related to brain metastases from ovarian carcinoma. So far, less than 600 cases were documented in the literature with an incidence among ovarian carcinoma patients ranging from 0.29% to 11.6%. The ovarian carcinoma was usually an advanced-stage epithelial serous carcinoma, and the median interval between diagnosis of ovarian carcinoma and brain metastases was 2 years. Most often, brain metastases, affected the cerebrum, were multiple and part of a disseminated disease. Treatment of brain metastasis has evolved over the years from whole brain radiotherapy (WBRT) only to multimodal therapy including surgical resection or stereotactic radiosurgery followed by WBRT and/or chemotherapy. The median survival after diagnosis of brain metastases was 6 months; nevertheless, a significantly better survival was achieved with multimodal therapy compared to WBRT only. It is suggested that brain imaging studies should be included in the followup of patients after treatment for ovarian carcinoma. PMID:22191058

    The therapeutic management of brain metastases depends upon their diagnosis and characteristics. It is therefore imperative that imaging provides accurate diagnosis, identification, size and localization information of intracranial lesions in patients with presumed cerebral metastatic disease. MRI exhibits superior sensitivity to CT for small lesions identification and to evaluate their precise anatomical location. The CT-scan will be made only in case of MRI's contraindication or if MRI cannot be obtained in an acceptable delay for the management of the patient. In clinical practice, the radiologic metastasis evaluation is based on visual image analyses. Thus, a particular attention is paid to the imaging protocol with the aim to optimize the diagnosis of small lesions and to evaluate their evolution. The MRI protocol must include: 1) non-contrast T1, 2) diffusion, 3) T2* or susceptibility-weighted imaging, 4) dynamic susceptibility contrast perfusion, 5) FLAIR with contrast injection, 6) T1 with contrast injection preferentially using the 3D spin echo images. The role of the nuclear medicine imaging is still limited in the diagnosis of brain metastasis. The Tc-sestamibi brain imaging or PET with amino acid tracers can differentiate local brain metastasis recurrence from radionecrosis but still to be evaluated. PMID:25649387

    Bone metastasis is associated with many symptoms such as bone pain, pathological fracture, and spinal cord compression. Especially, pain secondary to bone metastases is a serious problem in many patients with metastatic cancer. Radiotherapy can provide remarkable pain relief, reduce the requirement for analgesic drugs, and prevent pathological fracture or spinal cord compression with few complications in most patients. Many randomized controlled trials have shown equivalent extent of pain relief between single-fraction and multiple-fraction regimens. Reirradiation of painful bone metastases is effective for palliation of pain in non-responders or patients with recurrent pain after an initial satisfactory response to a previous radiation therapy. Systemic administration of radioisotopes is an important palliative care option for painful multifocal bone metastases detected on nuclear imaging; however, the application of this option depends on the histologic features of the tumor and distribution of the metastases. Metastatic spinal cord compression is the most frequent oncologic emergency and necessitates timely and appropriate treatment. External beam radiotherapy is commonly used for the treatment of metastatic spinal cord compression. Surgical decompression and stabilization should be considered for metastatic spinal cord compression or pathological fracture in select patients. Postoperative radiotherapy should be administered to patients who have undergone surgical intervention for bone metastases. For patients at a high risk for oncologic emergency, optimal prophylactic management is highly recommended. PMID:26602393

    Brain metastases are a common problem in solid malignancies and still represent a major cause of morbidity and mortality. With the ongoing improvement in systemic therapies, the expectations on the efficacy of brain metastases directed treatment options are growing. As local therapies against brain metastases continue to evolve, treatment patterns have shifted from a palliative "one-treatment-fits-all" towards an individualized, patient adapted approach. In this article we review the evidence for stereotactic radiation treatment based on the current literature. Stereotactic radiosurgery (SRS) as a local high precision approach for the primary treatment of asymptomatic brain metastases has gained wide acceptance. It leads to lasting tumor control with only minor side effects compared to whole brain radiotherapy, since there is only little dose delivered to the healthy brain. The same holds true for hypofractionated stereotactic radiotherapy (HFSRT) for large metastases or for lesions close to organs at risk (e.g. the brainstem). New treatment indications such as neoadjuvant SRS followed by surgical resection or postoperative local therapy to the resection cavity show promising data and are also highlighted in this manuscript. With the evolution of local treatment options, optimal patient selection becomes more and more crucial. This article aims to aid decision making by outlining prognostic factors, treatment techniques and indications and common dose prescriptions. PMID:27071010

    Stereotactic radiotherapy of brain metastases is increasingly proposed after polydisciplinary debates among experts. Its definition and modalities of prescription, indications and clinical interest regarding the balance between efficacy versus toxicity need to be discussed. Stereotactic radiotherapy is a 'high precision' irradiation technique (within 1mm), using different machines (with invasive contention or frameless, photons X or gamma) delivering high doses (4 to 25Gy) in a limited number of fractions (usually 1 to 5, ten maximum) with a high dose gradient. Dose prescription will depend on materials, dose constraints to organs at risk varying with fractionation. Stereotactic radiotherapy may be proposed: (1) in combination with whole brain radiotherapy with the goal of increasing (modestly) overall survival of patients with a good performance status, 1 to 3 brain metastases and a controlled extracranial disease; (2) for recurrence of 1-3 brain metastases after whole brain radiotherapy; (3) after complete resection of a large and/or symptomatic brain metastases; (4) after diagnosis of 3-5 asymptomatic new or progressing brain metastases during systemic therapy, with the aim of delaying whole brain radiotherapy (avoiding its potential neurotoxicity) and maintaining a high focal control rate. Only a strict follow-up with clinical and MRI every 3 months will permit to deliver iterative stereotactic radiotherapies without jeopardizing survival. Simultaneous delivering of stereotactic radiotherapy with targeted medicines should be carefully discussed. PMID:25640215

    Splenic metastases are rare. Usually, they are part of a disseminated disease and located on the splenic capsule. Common sources are breast cancer, lung cancer and malignant melanoma. SoLitary splenic metastases are rare, usuaLLy located in the splenic parenchyma and metastasizing via the hematogenous route. Splenic metastases from ovarian carcinoma are usuaLly part of a disseminated disease, located on the splenic capsule and metastasize via the peritoneum. Splenic metastases from endometriaL carcinoma are usuaLLy solitary, Located in the splenic parenchyma and metastasize via the hematogenous route. Splenic metastases from cervical carcinoma are divided equally between metastases as part of a disseminated disease and soLitary metastases. Less than 100 cases of solitary splenic metastases have been reported with half of them being metastases from female genital tract malignancies: 30--ovarian carcinoma; 11--endometriaL carcinoma; 8--cervical carcinoma; and 1--tubal carcinoma. Few cases have been reported of splenic rupture because of metastases from choriocarcinoma. Splenic metastases as part of a disseminated disease are associated with poor prognosis, and splenectomy--apart from cases in which it might assist in achieving optimaL debulking--is not effective. Solitary splenic metastases represent a more moderate disease and the treatment of choice is splenectomy. SoLitary splenic metastases may be detected after an interval from the diagnosis of the primary disease. Hence, patients who had been treated for female genital tract malignancy, even if they are asymptomatic, need a long-term follow-up, including serial imaging studies of the spleen. PMID:20929072

    This paper will focus on knowledge related to brain metastases from endometrial carcinoma. To date, 115 cases were documented in the literature with an incidence of 0.6% among endometrial carcinoma patients. The endometrial carcinoma was usually an advanced-stage and high-grade tumor. In most patients (~90%), brain metastasis was detected after diagnosis of endometrial carcinoma with a median interval from diagnosis of endometrial carcinoma to diagnosis of brain metastases of 17 months. Brain metastasis from endometrial carcinoma was either an isolated disease limited to the brain only (~50%) or part of a disseminated disease involving also other parts of the body (~50%). Most often, brain metastasis from endometrial carcinoma affected the cerebrum (~75%) and was solitary (~60%). The median survival after diagnosis of brain metastases from endometrial carcinoma was 5 months; however, a significantly better survival was achieved with multimodal therapy including surgical resection or stereotactic radiosurgery followed by whole brain radiotherapy (WBRT) and/or chemotherapy compared to WBRT alone. It is suggested that brain imaging studies should be considered in the routine follow up of patients with endometrial carcinoma and that the search for a primary source in females with brain metastases of unknown primary should include endometrial biopsy.

    It has been over a century since Perls described the first case of choroidal metastasis. For the next six decades only 230 cases were described in the literature. Today, however, ocular metastasis is recognized as the most common intraocular malignancy. Thanks to recent advances in treatment options for metastatic disease, patients are living longer, and choroidal metastases will become an increasingly important issue for oncologists and ophthalmologists alike. We summarize the current knowledge of choroidal metastases and examine their emerging systemic and local therapies. Targeted therapies for metastatic lung, breast, and colon cancer—the most common causes of choroidal metastases—are reviewed in detail with the goal of identifying the most effective treatment strategies.

    Central nervous system or brain metastases traditionally occur in 10-16% of metastatic breast cancer patients and are associated with a dismal prognosis. The development of brain metastases has been associated with young age, and tumors that are estrogen receptor negative, Her-2+ or of the basal phenotype. Treatment typically includes whole brain irradiation, or either stereotactic radiosurgery or surgery with whole brain radiation, resulting in an approximately 20% one year survival. The blood-brain barrier is a formidable obstacle to the delivery of chemotherapeutics to the brain. Mouse experimental metastasis model systems have been developed for brain metastasis using selected sublines of human MDA-MB-231 breast carcinoma cells. Using micron sized iron particles and MRI imaging, the fate of MDA-MB-231BR cells has been mapped: Approximately 2% of injected cells form larger macroscopic metastases, while 5% of cells remain as dormant cells in the brain. New therapies with permeability for the blood-brain barrier are needed to counteract both types of tumor cells. PMID:17473372

    Until recently, hepatic arterial therapies (HAT) had been used for colorectal liver metastases after failure of first-, second-, and third-line chemotherapies. HAT has gained greater acceptance in patients with liver-dominant colorectal metastases after failure of surgery or systemic chemotherapy. The current data demonstrate that HAT is a safe and effective option for preoperative downsizing, optimizing the time to surgery, limiting non-tumor-bearing liver toxicity, and improving overall survival after surgery in patients with colorectal liver-only metastases. The aim of this review is to present the current data for HAT in liver-only and liver-dominant colorectal liver metastases. PMID:27017870

    Purpose: To determine the efficacy and safety of radiosurgery in patients with large brain metastases treated with radiosurgery. Patients and Methods: Eighty patients with large brain metastases (>14 cm{sup 3}) were treated with radiosurgery between 1998 and 2009. The mean age was 59 {+-} 11 years, and 49 (61.3%) were men. Neurologic symptoms were identified in 77 patients (96.3%), and 30 (37.5%) exhibited a dependent functional status. The primary disease was under control in 36 patients (45.0%), and 44 (55.0%) had a single lesion. The mean tumor volume was 22.4 {+-} 8.8 cm{sup 3}, and the mean marginal dose prescribed was 13.8 {+-} 2.2 Gy. Results: The median survival time from radiosurgery was 7.9 months (95% confidence interval [CI], 5.343-10.46), and the 1-year survival rate was 39.2%. Functional improvement within 1-4 months or the maintenance of the initial independent status was observed in 48 (60.0%) and 20 (25.0%) patients after radiosurgery, respectively. Control of the primary disease, a marginal dose of {>=}11 Gy, and a tumor volume {>=}26 cm{sup 3} were significantly associated with overall survival (hazard ratio, 0.479; p = .018; 95% CI, 0.261-0.880; hazard ratio, 0.350; p = .004; 95% CI, 0.171-0.718; hazard ratio, 2.307; p = .006; 95% CI, 1.274-4.180, respectively). Unacceptable radiation-related toxicities (Radiation Toxicity Oncology Group central nervous system toxicity Grade 3, 4, and 5 in 7, 6, and 2 patients, respectively) developed in 15 patients (18.8%). Conclusion: Radiosurgery seems to have a comparable efficacy with surgery for large brain metastases. However, the rate of radiation-related toxicities after radiosurgery should be considered when deciding on a treatment modality.

    Background: Spillage of bile and gallstones due to accidental perforation of the gallbladder wall is often encountered during laparoscopic cholecystectomy. Although spilled stones were once considered harmless, there is increasing evidence that they can result in septic or other potential complications. Case Report: We report a case of spilled gallstones mimicking peritoneal metastases on radiological investigations; diagnosis was confirmed by diagnostic laparoscopy. Conclusion: Every effort should be made to retrieve spilled gallstones during laparoscopic cholecystectomy. When all the stones cannot be retrieved, it should be documented in the patient's medical records to avoid delay in the diagnosis of late complications. Diagnostic laparoscopy is useful when the radiological investigations are inconclusive. PMID:19366546

    Resection of colorectal liver metastases is a treatment standard because patients experience long-term disease-free survival or are even cured after undergoing this procedure. Improved surgical techniques for liver resection in combination with downsizing liver metastases by chemotherapy, interventions to induce liver hypertrophy before resection, and the use of ablative techniques have allowed us to expand the indications for liver surgery and local treatment in situations with limited metastatic colorectal cancer. Resectability and identification of patients who might benefit from liver surgery and local ablative techniques are key factors for the treatment of patients with colorectal cancer. Despite the wide acceptance of liver surgery and ablative techniques, there are many open questions on the management of limited metastatic disease, such as which patients benefit from an aggressive surgical approach, what the indications for ablative and other local techniques are, and what the role of chemotherapy is for patients with resectable or resected disease. Unfortunately, results of randomized trials are only available for a limited number of these questions. PMID:27249722

    Lung metastases occur in 10-20 % of patients with colorectal cancer. The biology of colorectal lung metastases is poorly understood, however lung metastases are more common in patients with rectal cancer and in patients with RAS mutations. Although the majority of patients have extrapulmonary disease, a small proportion of patients with lung metastases are suitable for lung metastasectomy and surgical resection has become a standard of care, based on data from retrospective series demonstrating a 5-year overall survival of 40-68 %. However, there remains uncertainty regarding the optimal management approach for these patients due to the lack of evidence from randomized controlled trials and current practice varies between institutions. For example, the role for neoadjuvant and adjuvant chemotherapy is not yet defined and there are no randomized trials comparing surgery with alternative treatment options such as radiofrequency ablation and stereotactic ablative radiotherapy. Further research is needed to improve the selection of patients for surgery, but favourable prognostic factors include a normal pre-operative CEA, solitary metastasis, complete resection and a long disease-free interval. There is also evidence that patients with resectable liver and lung metastases may benefit from resection of both sites of disease, and that re-resection may be of benefit in selected patients who relapse with resectable lung metastases. This article summarizes the biology of colorectal lung metastases and discusses the management of patients with lung metastases. PMID:26659389

    In oncosurgical approach to colorectal liver metastases, surgery remains considered as the only potentially curative option, while chemotherapy alone represents a strictly palliative treatment. However, missing metastases, defined as metastases disappearing after chemotherapy, represent a unique model to evaluate the curative potential of chemotherapy and to challenge current therapeutic algorithms. We reviewed recent series on missing colorectal liver metastases to evaluate incidence of this phenomenon, predictive factors and rates of cure defined by complete pathologic response in resected missing metastases and sustained clinical response when they were left unresected. According to the progresses in the efficacy of chemotherapeutic regimen, the incidence of missing liver metastases regularly increases these last years. Main predictive factors are small tumor size, low marker level, duration of chemotherapy, and use of intra-arterial chemotherapy. Initial series showed low rates of complete pathologic response in resected missing metastases and high recurrence rates when unresected. However, recent reports describe complete pathologic responses and sustained clinical responses reaching 50%, suggesting that chemotherapy could be curative in some cases. Accordingly, in case of missing colorectal liver metastases, the classical recommendation to resect initial tumor sites might have become partially obsolete. Furthermore, the curative effect of chemotherapy in selected cases could lead to a change of paradigm in patients with unresectable liver-only metastases, using intensive first-line chemotherapy to intentionally induce missing metastases, followed by adjuvant surgery on remnant chemoresistant tumors and close surveillance of initial sites that have been left unresected.

    Carcinosarcoma of the prostate is an uncommon malignancy with poor long-term prognosis. The cancer is typically discovered at an advanced stage, and with less than 100 reported cases, there is limited literature concerning treatment options. Our patient presented with a history of benign prostatic hypertrophy, erectile dysfunction, and nocturia. Biopsy of his prostate indicated that the patient had prostatic adenocarcinoma, but histopathology after prostatectomy revealed carcinosarcoma. It has been over six years since this patient's diagnosis of carcinosarcoma. Over this span of time, he has received a radical prostatectomy, radiotherapy, and androgen ablative therapy. The patient also developed multiple lung metastases that have been treated with video-assisted thoracic surgery and stereotactic body radiosurgery. Overall, he has remained unimpaired and in good condition despite his aggressive form of cancer. PMID:24294528

    Despite the fact that effective therapy does not currently exist for the majority of patients presenting with metastases of unknown primary site, the last decade has witnessed significant advances in the approach to this heterogeneous disease. The use of modern pathologic techniques that frequently provide better diagnostic precision and the recognition of specific subgroups with a favorable prognosis and responsiveness to treatment has improved the outcome for some patients. Currently the diagnostic strategy should emphasize the rapid identification of patients likely to benefit from available therapy, whereas clinical research should focus on the development of more effective treatments for those patients with unresponsive tumors. In the future, continued improvements in the molecular characterization of these tumors will likely enhance understanding of the metastatic process, allow for more specific definitions of cell lineage, and provide insights for better therapy.

    Colorectal (CRC) and gastroesophageal (GEC) cancers unusually spread to the bone. However, bone metastases (BM) are responsible for skeletal-related events (SREs) associated with an altered quality of life. Aiming to describe the characteristics and prognostic influence of BM from gastro-intestinal cancers, we performed a retrospective analysis of prospectively collected data in patients treated in our institution (1996-2006). 189 patients (5.5 %) developed BM: 79 with GEC and 110 with CRC. 57 patients had bone-exclusive metastases. In univariate analyses, the median time to BM occurrence was correlated with the primary tumour (PT) localisation, surgery, histology and TNM staging. However, in multivariate analyses, the occurrence delay was significantly shorter only for patients with GEC (HR 2.1), N1-2 status (HR 1.9), M1 status (HR 2.4), and epidermoid carcinoma (HR 6.0). Pain was the most frequent clinical sign leading to BM diagnosis (77.2 %). SRE occurred in 55 % of patients. Median overall survivals (OSs) of patients with CRC and GEC were 9.4 months [95 % confidence interval (95 % CI) 6.4-11.1] and 3.4 months (95 % CI 2.5-9.0), respectively. In univariate analyses, OS was correlated with PT surgery and NM staging, and the number of BM. In multivariate analyses, only the PT surgery and the number of BM remained correlated with OS. Our results suggest that there may be a subset of patients associated with a quicker development of BM. Given their higher risk of SRE, they could benefit from an early screening, calling for further prospective studies encompassing patients with and without BM. PMID:25381591

    Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient. PMID:16475029

    Background: Brain metastases affect up to 30% of patients with cancer. Management of brain metastases continues to evolve with ever increasing focus on cognitive preservation and quality of life. This manuscript reviews current state of brain metastases management and discusses various treatment controversies with focus on future clinical trials. Stereotactic radiosurgery (SRS) and whole-brain radiotherapy (WBRT) are discussed in context of multiple (4+ brain metastases) as well as new approaches combining radiation and targeted agents. A brief discussion of modified WBRT approaches, including hippocampal-avoidance WBRT (HA-WBRT) is included as well as a section on recently presented results of Radiation Therapy Oncology Group (RTOG) 0614, a randomized, double-blind, placebo-controlled trial of menantine for prevention of neurocognitive injury after WBRT. Methods: A search of selected studies relevant to management of brain metastases was performed in PubMed as well as in various published meeting abstracts. This data was collated and analyzed in context of contemporary management and future clinical trial plans. This data is presented in tabular form and discussed extensively in the text. Results: The published data demonstrate continued evolution of clinical trials and management strategies designed to minimize and/or prevent cognitive decline following radiation therapy management of brain metastases. Hippocampal avoidance whole-brain radiation therapy (HA-WBRT) and radiosurgery treatments for multiple brain metastases are discussed along with preliminary results of RTOG 0614, a trial of memantine therapy to prevent cognitive decline following WBRT. Trial results appear to support the use of memantine for prevention of cognitive decline. Conclusions: Different management strategies for multiple brain metastases (>4 brain metastases) are currently being evaluated in prospective clinical trials to minimize the likelihood of cognitive decline following WBRT.

    Peritoneal seedings of a colorectal tumor represent the second most frequent site of metastasis (after the liver). In the era of 5-fluorouracil (5-FU)-only chemotherapy, the prognosis was poor for colorectal cancer with peritoneal metastases. Within the last few years, new chemotherapeutic and targeted agents have improved the prognosis; however, the response to these treatments seems to be lower than that for liver metastases. The combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have further improved both disease-free survival and overall survival. Keeping this in mind, every patient presenting with peritoneal metastases from colorectal cancer should be evaluated and receive adequate treatment, if possible in the above-mentioned combination. This paper reviews recent advancements in the therapy of peritoneal carcinomatosis. PMID:26424828

    Colorectal cancer (CRC) is a common malignancy worldwide. In CRC patients, metastases are the main cause of cancer-related mortality. In a group of metastatic CRC patients, the metastases are limited to a single site (solitary organ); the liver and lungs are the most commonly involved sites. When metastatic disease is limited to the liver and/or lungs, the resectability of the metastatic lesions will dictate the management approach and the outcome. Less commonly, the site of solitary organ CRC metastasis is the peritoneum. In these patients, cytoreduction followed by hyperthermic intraperitoneal chemotherapy may improve the outcome. Rarely, CRC involves other organs, such as the brain, bone, adrenals and spleen, as the only site of metastatic disease. There are limited data to guide clinical practice in these cases. Here, we have reviewed the disease characteristics, management approaches and prognosis based on the metastatic disease site in patients with CRC with metastases to a single organ. PMID:26557001

    Conventional bone scintigraphy is still the standard investigation for the detection of bone metastases, especially in breast and prostate cancer. In unclear scintigraphic uptakes in the appendicular skeleton conventional x-rays are problem solving in most of the cases. In unclear uptakes in the axial skeleton additional performance of SPECT/CT can increase the specificity. Fluoride-PET/CT is superior to conventional bone scintigraphy but is not yet available in clinical routine. Patients with high-risk breast cancer and patients with lung cancer should be staged with FDG-PET/CT primarily. An additional bone scan is than superfluous. The great advantage of FDG-PET/CT is the fact that bone metastases and organ metastases can be detected in the same investigation. There is a clear trend of shifting patients from conventional nuclear medicine to PET/CT. PMID:20029782

    Melanomas have a high rate of brain metastases. Both the functional prognosis and the overall survival are poor in these patients. Until now, surgery and radiotherapy represented the two main modalities of treatment. Nevertheless, due to the improvement in the management of the extracerebral melanoma, the systemic treatment may be an option in patients with brain metastases. Immunotherapy with anti-CTLA4 (cytotoxic T-lymphocyte-associated protein 4) - ipilimumab - or BRAF (serine/threonine-protein kinase B-raf) inhibitors - vemurafenib, dabrafenib - has shown efficacy in the management of brain metastases in a- or pauci-symptomatic patients. Studies are ongoing with anti-PD1 (programmed cell death 1) and combinations of targeted therapies associating anti-RAF (raf proto-oncogene, serine/threonine kinase) and anti-MEK (mitogen-activated protein kinase kinase).

    The outcome of patients with prostate cancer (PCa) is mainly dependent on the presence or absence of distant metastases. Although several advances have been made in understanding the biological basis of this tumor, the mechanisms underlying PCa metastatic spread are not fully clear. The lack of a clear origin for PCa metastasis may be partially due to the evidence of PCa heterogeneity between primary tumor and metastases and among different metastatic sites. Cross-metastatic seeding and the de novo monoclonal seeding of daughter metastases have been proposed as crucial events during metastasis. This process requires the contribution of tumor environment, which modulates cancer cell homing and growth, and involves several components including cancer stem cells (CSCs), tumor secreted microvesicles, circulating tumor cells (CTCs), and immune cells. In this review, we have focused on the recent findings on the origin of prostate metastasis, showing the contribution of tumor microenvironment to this evolutionary process. PMID:26363603

    Abstract The role of surgical therapy in patients with liver metastases from gastric cancer is still controversial. In this study, we investigated the results obtained with local treatment of hepatic metastases in patients with gastric cancer, by performing a systematic literature review and meta-analysis. We performed a systematic review and meta-analysis of observational studies published between 1990 and 2014. These works included multiple studies that evaluated the different survival rate among patients who underwent local treatment, such as hepatectomy or radiofrequency ablation, for hepatic metastases derived from primary gastric cancer. The collected studies were evaluated for heterogeneity, publication bias, and quality, and a pooled hazard ratio (HR) was calculated with a confidence interval estimated at 95% (95% CI). After conducting a thorough research among all published works, 2337 studies were found and after the review process 11 observational studies were included in the analysis. The total amount of patients considered in the survival analysis was 1010. An accurate analysis of all included studies reported a significantly higher survival rate in the group of patients who underwent the most aggressive local treatment for hepatic metastases (HR 0.54, 95% CI 0.46–0.95) as opposed to patients who underwent only palliation or systemic treatment. Furthermore, palliative local treatment of hepatic metastases had a higher survival rate if compared to surgical (without liver surgery) and systemic palliation (HR 0.50, 95% CI 0.26–0.96). Considering the only 3 studies where data from multivariate analyses was available, we found a higher survival rate in the local treatment groups, but the difference was not significant (HR 0.50, 95% CI 0.22–1.15). Curative and also palliative surgery of liver metastases from gastric cancer may improve patients’ survival. However, further trials are needed in order to better understand the role of surgery in this

    Bone metastases are the most common source of pain for patients with cancer. For pain that is refractory to conventional measures, microwave ablation (MWA) is an emerging alternative therapy. Studies show that MWA is effective in reducing pain and analgesic requirements while improving function. This article describes studies of MWA that include patients with bone metastases to a variety of locations from a range of primary malignancies. Although studies are limited, MWA has proven to be well tolerated with impressive efficacy.

    Congenital fibrosarcomas are malignant tumors that arise in soft tissues. In infants this unique tumor does not commonly metastasize, even though there may be local recurrences. We report here a boy who had congenital fibrosarcoma in his right foot, which was completely excised at the age of 3 days. Four months later, a solitary encapsulated metastasis emerged in thoracic chest wall, which was operated. During adjuvant chemotherapy he developed histologically confirmed fibrosarcoma metastases in the heart. After extended treatment with cyclophosphamide/topotecan and gemcitabine/docetaxel, the heart tumors disappeared and he has been in complete remission for 3 years. PMID:22217490

    Meningioma accounts for approximately one-third of primary central nervous system tumors. Most meningiomas are benign, although up to one third are classified as atypical or malignant. We describe a 63-year Caucasian male presenting with pleural metastases from an intracranial meningioma. Distant metastases from meningiomas are infrequently found in clinical practice and mostly are associated with atypical or malignant meningiomas. There is no standard treatment; however surgical resection of both the primary and metastatic lesions is the safest therapy. The overall prognosis of atypical meningiomas is poor.

    For decades, surgical resection of pulmonary metastases has been performed; despite limited randomized data, surgery is increasingly accepted as an integral part in the management of metastatic disease. Long-term results indicate resection is potentially curative with significantly improved survival following complete resection. Recurrence, however, is not uncommon with many patients undergoing repeat resection. With advancing surgical technique and adjuvant therapies, patients with high or recurrent tumor burden are increasingly afforded disease control and potential cure. In this review, the prognostic characteristics of pulmonary metastases from sarcoma, preoperative evaluation, operative technique, long-term outcomes, and management of complex patients are highlighted.

    Some three hundred thousand of patients die of cancers yearly and at least 20-40%, i. e., 60,000-120,000 of them suffered from brain metastases. Those with such metastases have a generally poor outcome with a median survival of 1-2 months with steroids only, and approximately 6 months with whole-brain radiation therapy (WBRT). The results of important and historical clinical trials including surgery, WBRT, stereotactic radiosurgery (SRS), and chemotherapy are reviewed. Surgery with WBRT has been used in the treatment of a single brain metatasis with a diameter of more than 3 cm, while survival time of those patients is approximately 12 months. SRS including gamma knife is widely used for treatment of small and multiple brain metastases. However, many clinical studies have revealed that SRS+WBRT is superior to WBRT or SRS alone in survival time and local control rates. The accurate incident rates of radiation-induced dementia or neurological deficit are still unclear, so the problem and possible avoidance of an additional WBRT after surgery or SRS are discussed. To improve neurologic function and survival, the treatment for patients with brain metastases should be selected with accurate knowledge of EBM. PMID:15853211

    The objective of this study was to assess reduction in cerebral edema following linear accelerator radiosurgery (LINAC) as first line therapy for brain metastasis. We reviewed the medical records of all patients who underwent LINAC radiosurgery for brain metastasis at our institution during 2010-2012, and who had not previously undergone either surgery or whole brain radiotherapy. Data were analyzed for 55 brain metastases from 46 patients (24 males), mean age 59.9 years. During the 2 months following LINAC radiosurgery, the mean steroid dose decreased from 4.8 to 2.6 mg/day, the mean metastasis volume decreased from 3.79±4.12 cc to 2.8±4.48 cc (p=0.001), and the mean edema volume decreased from 16.91±30.15 cc to 12.85±24.47 cc (p=0.23). The 17 patients with reductions of more than 50% in brain edema volume had single metastases. Edema volume in the nine patients with two brain metastases remained stable in five patients (volume change <10%, 0-2 cc) and increased in four patients (by >10%, 2-14 cc). In a subanalysis of eight metastases with baseline edema volume greater than 40 cc, edema volume decreased from 77.27±37.21 cc to 24.84±35.6 cc (p=0.034). Reductions in brain edema were greater in metastases for which non-small-cell lung carcinoma and breast cancers were the primary diseases. Overall, symptoms improved in most patients. No patients who were without symptoms or who had no signs of increased intracranial pressure at baseline developed signs of intracranial pressure following LINAC radiosurgery. In this series, LINAC stereotactic radiosurgery for metastatic brain lesions resulted in early reduction in brain edema volume in single metastasis patients and those with large edema volumes, and reduced the need for steroids.

    Questions Should surgery be considered for colorectal cancer (crc) patients who have liver metastases plus (a) pulmonary metastases, (b) portal nodal disease, or (c) other extrahepatic metastases (ehms)? What is the role of chemotherapy in the surgical management of crc with liver metastases in (a) patients with resectable disease in the liver, or (b) patients with initially unresectable disease in the liver that is downsized with chemotherapy (“conversion”)? What is the role of liver resection when one or more crc liver metastases have radiographic complete response (rcr) after chemotherapy? Perspectives Advances in chemotherapy have improved survival in crc patients with liver metastases. The 5-year survival with chemotherapy alone is typically less than 1%, although two recent studies with folfox or folfoxiri (or both) reported rates of 5%–10%. However, liver resection is the treatment that is most effective in achieving long-term survival and offering the possibility of a cure in stage iv crc patients with liver metastases. This guideline deals with the role of chemotherapy with surgery, and the role of surgery when there are liver metastases plus ehms. Because only a proportion of patients with crc metastatic disease are considered for liver resection, and because management of this patient population is complex, multidisciplinary management is required. Methodology Recommendations in the present guideline were formulated based on a prepublication version of a recent systematic review on this topic. The draft methodology experts, and external review by clinical practitioners. Feedback was incorporated into the final version of the guideline. Practice Guideline These recommendations apply to patients with liver metastases from crc who have had or will have a complete (R0) resection of the primary cancer and who are being considered for resection of the liver, or liver plus specific and limited ehms, with curative intent. 1(a).

    Melanoma is a leading cause of lost productivity due to premature cancer mortality. Melanoma frequently spreads to the brain and is associated with rapid deterioration in quality and quantity of life. Until now, treatment options have been restricted to surgery and radiotherapy, although neither modality has been well studied in clinical trials. However, the new immune checkpoint inhibitors and molecularly targeted agents that have been introduced for treatment of metastatic melanoma are active against brain metastases and offer new opportunities to improve disease outcomes. New challenges arise, including how to integrate or sequence multiple treatment modalities, and current practice varies widely. In this Review, we summarise evidence for the treatment of melanoma brain metastases, and discuss the rationale and evidence for combination modalities, highlighting areas for future research.

    Pain management for painful bony metastases is the most important problem for symptom relief of terminally-ill cancer patients. Pathological fractures often decrease the activity of daily life (ADL) of patients, and cause deterioration of the quality of life (QOL) and prognosis. Basically pharmacological therapies of the World Health Organization (WHO) method are essential for symptom relief from cancer pain. This article provides the latest pain managements (palliative irradiation, bisphosphonate, orthopedic surgery, percutaneous vertebroplasty and radiopharmaceutical therapy) of bony metastases, and mentions the indications and the problems of these interventions. In consideration to prognosis, the QOL and patient's needs, medical staffs have to perform multidisciplinary approach for providing suitable palliative care. PMID:16582515

    Prostate carcinoma, when metastatic, typically involves bone and produces both osteoblastic and osteolytic changes. A 73-year-old man was admitted to our department because of unilateral progressive proptosis and visual blurriness for 3 months. The patient had a history of prostate adenocarcinoma diagnosis 5 years ago. We report a case of orbital involvement presented that intraorbital mass (including periocular structures), temporal bone and temporal muscle from prostate cancer. The mass was removed with total excision. Despite the frequency of bone metastasis in prostatic carcinoma, triple orbital metastases are extremely rare. The best of our knowledge, prostate adenocarcinoma and its triple (temporal bone, temporal muscle and intraorbital mass) orbital metastases have not been published previously. Metastatic orbital tumor secondary to prostate cancer should be considered in patients who have varying degrees of eye symptoms. PMID:27591068

    Studies of the cancer genome have demonstrated that tumors are comprised of multiple sub-clones with varied genetic and phenotypic properties. However, little is known about how metastases arise and evolve from these sub-clones. To understand the cellular dynamics that drive metastasis, we used multi-color lineage tracing technology in an autochthonous mouse model of pancreatic cancer. Here, we report that precursor lesions exhibit significant clonal heterogeneity but that this diversity decreases during pre-malignant progression. Furthermore, we present evidence that a significant fraction of metastases are polyclonally seeded by distinct tumor sub-clones. Finally, we show that clonality during metastatic growth – leading to either monoclonal or polyclonal expansion – differs based on the site of metastatic invasion. These results provide an unprecedented window into the cellular dynamics of tumor evolution and suggest that heterotypic interactions between tumor subpopulations contribute to metastatic progression in native tumors.

    Lung metastasectomy can prolong survival in patients with metastatic colorectal carcinoma. Thermal ablation offers a potential solution with similar reported survival outcomes. It has minimal effect on pulmonary function, or quality of life, can be repeated, and may be considered more acceptable to patients because of the associated shorter hospital stay and recovery. This review describes the indications, technique, reported outcomes, complications and radiologic appearances after thermal ablation of colorectal lung metastases. PMID:26697202

    Background: The incidence of neuroendocrine tumours (NET) has increased over the past three decades. Hepatic metastases which occur in up to 75% of NET patients significantly worsen their prognosis. New imaging techniques with increasing sensitivity enabling tumour detection at an early stage have been developed. The treatment encompasses a panel of surgical and non-surgical modalities. Methods: This article reviews the published literature related to management of hepatic neuroendocrine metastases. Results: Abdominal computer tomography, magnetic resonance tomography and somatostatin receptor scintigraphy are widely accepted imaging modalities. Hepatic resection is the only potentially curative treatment. Liver transplantation is justified in highly selected patients. Liver-directed interventional techniques and locally ablative measures offer effective palliation. Promising novel therapeutic options offering targeted approaches are under evaluation. Conclusions: The treatment of neuroendocrine liver metastases still needs to be standardized. Management in centres of expertise should be strongly encouraged in order to enable a multidisciplinary approach and personalized treatment. Development of molecular prognostic factors to select treatment according to patient risk should be attempted. PMID:20662787

    2014-01-01

    Pancreatic neuroendocrine tumor (P-NET) is rare and slow-growing. Current classifications predict its prognosis and postoperative recurrence. Curative resection is ideal, although often difficult, because over 80% of patients have unresectable multiple liver metastases and extrahepatic metastasis. Aggressive surgery for liver metastases is important to improve survival. Aggressive or cytoreductive surgery for liver metastases is indicated to reduce hormone levels and improve symptoms and prognosis. Liver transplantation was originally conceived as an ideal therapy for unresectable liver metastases. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases. Surgeons still face questions in deciding the best surgical scenario in patients with P-NET with unresectable liver metastases. PMID:25232452

    The most common sites of metastatic differentiated thyroid cancer are the neck lymph nodes, while distant metastases typically involve the lungs, the bones, and less frequently the brain. Uncommon metastatic sites include the liver, adrenal gland, kidney, pancreas, and skin. The epidemiological aspects of thyroid metastases in rare sites are largely unknown and their identification could have a significant impact on patients management. A mini-series of unusual metastatic sites of thyroid carcinoma is proposed as a contribution to current knowledge on anatomopathological characteristics and clinical outcome. Of the six cases that were assessed, the metastases were the following: skin metastases (2), skin and pancreas metastases (1), renal metastasis (1), adrenal metastasis (1), and liver metastasis (1). In our experience, metastases in rare sites do not always represent a negative prognostic factor for disease outcome. In fact they can occur as single distant lesion and if surgically resectable, their treatment can also lead to local disease remission. PMID:26662609

In every case, the diagnosis of IM was proven histopathologically on breast biopsy specimens. Overall, 187 IM were identified. IM had inconsistent MRI features, which cannot be clearly classify as benign or malignant. IM should be taken into consideration in the differential diagnosis of breast lesions to avoid possible misinterpretations. PMID:27133668

    Management of Neuroendocrine liver metastases (NELM) is challenging. The presence of NELM worsens survival outcome and almost 10% of all liver metastases are neuroendocrine in origin. There is no firm consensus on the optimal treatment strategy for NELM. A systematic search of the PubMed database was performed from 1995–2010, to collate the current evidence and formulate a sound management algorithm. There are 22 case series with a total of 793 patients who had undergone surgery for NELM. The overall survival ranges from 46–86% at 5 years, 35–79% at 10 years, and the median survival ranges from 52–123 months. After successful cytoreductive surgery, the mean duration of symptom reduction is between 16–26 months, and the 5-year recurrence/progression rate ranges from 59–76%. Five studies evaluated the efficacy of a combination cytoreductive strategy reporting survival rate of ranging from 83% at 3 years to 50% at 10 years. To date, there is no level 1 evidence comparing surgery versus other liver-directed treatment options for NELM. An aggressive surgical approach, including combination with additional liver-directed procedures is recommended as it leads to long-term survival, significant long-term palliation, and a good quality of life. A multidisciplinary approach should be established as the platform for decision making. PMID:22319650

    Benign leiomyomas of the uterus are uncommonly found in association with benign smooth muscle tumors beyond the confines of the uterus. Benign metastasizing leiomyoma (BML) is a rare disease in which the lung is described to be the most afflicted extrauterine organ. We present a brief review of the literature, along with case reports for four patients who were followed up after resection of a pulmonary lesion or after pathological confirmation by biopsy. The clinical course of BML varies from chronic asymptomatic appearance to rapid progression, leading to respiratory failure and death. Our BML patients did not complain of pulmonary symptoms, such as cough, dyspnea, or chest tightness. Pathology revealed benign leiomyomas with no atypia and mitotic activity <5 per 10 high-power field. Immunohistochemical staining was positive for actin and desmin. A standard treatment for BML has not yet been established. Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy. Benign metastasizing leiomyoma can be observed in postmenopausal women. We observed four patients who did not receive adjuvant hormonal therapy because they were postmenopausal or perimenopausal. All patients are still healthy and show no evidence of recurrence or progression of the disease. PMID:24134076

    Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung), or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

    Metastases to the spine from non-hepatocellular carcinomas, such as cholangiocarcinoma and angiosarcoma, occur rarely. With improvements in oncologic care, the number of patients diagnosed with metastatic cancer is expected to increase. We performed a systematic review of the literature to assess the clinical presentation, treatment, outcome and survival of patients diagnosed with non-hepatocellular carcinoma spinal metastasis using PubMed, Embase, CINAHL, Cochrane Library and Web of Science. We identified 19 cases of spinal metastases from non-hepatocellular carcinomas that fit our pre-specified criteria. The mean age at presentation was 62.3years and cholangiocarcinoma was the most common subtype. Patients frequently presented with pain, weakness or paraparesis and at the time of diagnosis, most of them had multi-level involvement of the spine. A majority of patients with spinal metastasis were treated either with radiation or chemotherapy or received no treatment. A minority of the reports included information on survival, which revealed a median survival of 1.5months following diagnosis of the spinal metastasis. Although there is a paucity of published literature on non-hepatocellular carcinoma spinal metastasis, this systematic review provides descriptive clinical characteristics of these patients.

    The distinction between primary and secondary (metastatic) ovarian tumors is essential for the selection of appropriate surgical interventions, chemotherapeutic treatment and prognostic evaluation for the patient. Metastatic tumors of the ovary range between 5 % and 30 %. The majority of ovarian metastases in Europe and North America derive from colorectal (25-50 %) and breast cancers (8-25 %). A major issue is the differential diagnosis of mucinous tumors. Major features favoring metastasis include bilaterality, size < 10 cm, ovarian surface involvement, extensive intra-abdominal spread, and infiltrative growth within the ovary involving the corpus albicans and corpora lutea. An algorithm using bilaterality and tumor size (cut-off 10 cm) allows correct categorization in approximately  85 % of the cases. Although immunohistochemistry (especially CK7 and CK20 in mucinous tumors) using a panel of antibodies plays a valuable role and is paramount in the diagnosis, the results must be interpreted with caution and within the relevant clinical and histopathological context. It is necessary to note that the correct diagnosis of ovarian metastases always needs interdisciplinary and multidisciplinary approaches. PMID:24859239

    Pelvic bone metastases are a growing concern in the field of orthopedic surgery. Patients with pelvic metastasis are individually different with different needs of treatment in order to attain the best possible quality of life despite the advanced stage of disease. A holistic collaboration among the oncologist, radiation therapist, and orthopedic surgeon is mandatory. Special attention has to be directed to osteolytic lesions in the periacetabular region as they can provoke pathological fractures and subsequent functional impairment. Different reconstruction techniques for the pelvis are available; the choice depends on the patient's prognosis, size of the bone defect, and response of the tumor to adjuvant treatment. If all the conservative treatments are exhausted and the patient is not eligible for surgery, one of the various percutaneous ablation procedures can be considered. We propose a pelvic analogue to the treatment algorithm in long bone metastasis and a scoring system in pelvic metastasis. This algorithm aims to simplify the teamwork and to avoid under- or overtreatment of pelvic bone metastases. PMID:25810925

    Introduction Selected patients with isolated breast cancer liver metastases (BCLM) may benefit from surgical management; however, indications remain unclear and the risks may outweigh the benefits in patients with a generally poor prognosis. Methods Between 1998 and 2006, 17 patients diagnosed with BCLM were considered for surgical management (<4 tumours, tumour <4 cm in diameter and no/stable extrahepatic metastases). Peri-operative and outcomes data were analysed and compared. Results Eight patients were found to have extensive or untreatable disease on staging laparoscopy and intra-operative ultrasound (SL/IOUS). The remaining nine patients underwent surgical management [seven laparoscopic radiofrequency ablations (RFA) and two hepatic resections]. Median length of follow-up for patients treated surgically was 40.0 months, median disease-free survival (DFS) was 32.2 months and median time to disease progression was 17.7 months. Of the eight patients not amenable to surgery, median length of follow-up was 21.8 months. Conclusion SL/IOUS prevented unnecessary laparotomy in half of the patients taken to the operating room for surgical treatment of BCLM. In patients with BCLM, SL/IOUS should be considered standard of care before surgical intervention. The small number of patients and short follow-up may be inadequate to determine the true value of surgical management in this group of patients with BCLM. PMID:21418133

    Cancer immunotherapy has been a subject of intense research over the last several years, leading to new approaches for modulation of the immune system to treat malignancies. Immune checkpoint inhibitors (anti-CLTA-4 antibodies and anti-PD-1/PD-L1 antibodies) potentiate the host's own antitumor immune response. These immune checkpoint inhibitors have shown impressive clinical efficacy in advanced melanoma, metastatic kidney cancer, and metastatic non-small cell lung cancer (NSCLC)-all malignancies that frequently cause brain metastases. The immune response in the brain is highly regulated, challenging the treatment of brain metastases with immune-modulatory therapies. The immune microenvironment in brain metastases is active with a high density of tumor-infiltrating lymphocytes in certain patients and, therefore, may serve as a potential treatment target. However, clinical data of the efficacy of immune checkpoint inhibitors in brain metastases compared with extracranial metastases are limited, as most clinical trials with these new agents excluded patients with active brain metastases. In this article, we review the current scientific evidence of brain metastases biology with specific emphasis on inflammatory tumor microenvironment and the evolving state of clinical application of immune checkpoint inhibitors for patients with brain metastases.

    Given the encouraging results from our previous work on the clinical application of BNCT on non-resectable, chemotherapy resistant liver metastases, we explore the possibility to extend our technique to lung metastases. A fundamental requirement for BNCT is achieving higher 10B concentrations in the metastases compared to those in healthy tissue. For this reason we developed a rat model with lung metastases in order to study the temporal distribution of 10B concentration in tissues and tumoral cells. Rats with induced lung metastases from colon adenocarcinoma were sacrificed two hours after intraperitoneal Boronphenylalanine infusion. The lungs were harvested, frozen in liquid nitrogen and subsequently histological sections underwent neutron autoradiography in the nuclear reactor Triga Mark II, University of Pavia. Our findings demonstrate higher Boron uptake in tumoral nodules compared to healthy lung parenchyma 2 hours after Boronphenylalanine infusion.

    PubMed Central

    Friberg, Sten; Nyström, Andreas

    2015-01-01

    BACKGROUND Metastatic cells from a primary tumor can occur before the primary cancer is detected. Metastatic cells can also remain in the patient for many years after removal of the primary tumor without proliferating. These dormant malignant cells can awaken and cause recurrent disease decades after the primary treatment. The purpose of this article is to review the clinical evidence for early dissemination and late recurrences in human malignant tumors. We used the following definitions: dormancy of cells may be defined as a nonproliferating state or an arrest in the cell cycle that results in a prolonged G0 phase. If one accepts the term “late metastases” to indicate a period exceeding 10 years from the removal of the primary tumor, then the two malignancies in which this occurs most frequently are cutaneous malignant melanoma (CMM) and renal cell carcinoma (RCC). METHODS PubMed, Web of Science, and Scopus were searched with the keywords “metastases,” “early dissemination,” “late recurrences,” “inadvertently transmitted cancer,” “tumor growth rate,” “dormancy,” “circulating tumor cells,” and “transplantation of cancer.” RESULTS Several case reports of early dissemination and late recurrences of various types of malignancies were found. Analyses of the growth rates of several malignant tumors in the original host indicated that the majority of cancers had metastasized years before they were detected. CMM, RCC, and malignant glioblastoma were the three most common malignancies resulting from an organ transplantation. CMM and RCC were also the two most common malignancies that showed dormancy. In several cases of transplanted CMM and RCC, the donor did not have any known malignancy or had had the malignancy removed so long ago that the donor was regarded as cured. CONCLUSION (1) Metastases can frequently exist prior to the detection of the primary tumor. (2) Metastatic cells may reside in organs in the original host that are not

    Bone metastases are dejected consequences of many types of tumors including breast, prostate, lung, kidney and thyroid cancers. This complicated process begins with the successful tumor cell epithelial–mesenchymal transition, escape from the original site, and penetration into circulation. The homing of tumor cells to the bone depends on both tumor-intrinsic traits and various molecules supplied by the bone metastatic niche. The colonization and growth of cancer cells in the osseous environment, which awaken their dormancy to form micro- and macro-metastasis, involve an intricate interaction between the circulating tumor cells and local bone cells including osteoclasts, osteoblasts, adipocytes and macrophages. In this review, we discuss the most recent advances in the identification of new molecules and novel mechanisms during each step of bone metastasis that may serve as promising therapeutic targets.

    Skeletal metastases are common in patients with cancers of the breast, lung, kidneys, prostate, and thyroid gland. Two main aspects have to be considered in diagnostic imaging. Screening in patients with known primary tumor. Triphasic Sczintigraphy is the imaging modality of choice for this purpose, however, whole-body-magnetic resonance imaging seems to be a potential alternative. Evaluation of suspicious skeletal lesions, which is currently dominated by magnetic resonance imaging. New perspectives for preoperative staging as well as for reconstruction- and implant-surgery are made available by multidetector-row-computed tomography. Non-invasive techniques, such as diffusion weighted imaging, positron emission tomography and positron emission tomography/computed tomography are now available, which seem to have potential for reliable tissue characterization. This feature is critical for monitoring treatment response in oncology. PMID:12621852

    Tuberculosis remains one of the most important infectious disease worldwide and skeletal form has an incidence between 3% and 10%, depending on geographic area. The thoracolumbar junction is the most commonly involved in vertebral tuberculosis; some radiologic features are specifics, but other could be indistinguishable from that of lymphoma or metastases. We discuss the case of a 80-year-old man presented with a 2-month history of thoracolumbar pain, fatigability and fever. The vertebral radiography showed narrowing of the intervertebral disc space between T1 and T12, adjacent irregularity, erosion and lisis of vertebres, features visibles also on computed tomography. After the exclusion of the other causes of osteolisis, we started a standard regimen of tuberculostatic treatment and after one month of treatment the symptoms of patient improved noticeably. Other problems of diagnostic and treatment modalities of spinal tuberculosis are discussed. PMID:20509287

    Purpose: Based on reports of safety and efficacy, stereotactic body radiotherapy (SBRT) for treatment of malignant spinal tumors was initiated at our institution. We report prospective results of this population at Mayo Clinic. Materials and Methods: Between April 2008 and December 2010, 85 lesions in 66 patients were treated with SBRT for spinal metastases. Twenty-two lesions (25.8%) were treated for recurrence after prior radiotherapy (RT). The mean age of patients was 56.8 {+-} 13.4 years. Patients were treated to a median dose of 24 Gy (range, 10-40 Gy) in a median of three fractions (range, 1-5). Radiation was delivered with intensity-modulated radiotherapy (IMRT) and prescribed to cover 80% of the planning target volume (PTV) with organs at risk such as the spinal cord taking priority over PTV coverage. Results: Tumor sites included 48, 22, 12, and 3 in the thoracic, lumbar, cervical, and sacral spine, respectively. The mean actuarial survival at 12 months was 52.2%. A total of 7 patients had both local and marginal failure, 1 patient experienced marginal but not local failure, and 1 patient had local failure only. Actuarial local control at 1 year was 83.3% and 91.2% in patients with and without prior RT. The median dose delivered to patients who experienced local/marginal failure was 24 Gy (range, 18-30 Gy) in a median of three fractions (range, 1-5). No cases of Grade 4 toxicity were reported. In 1 of 2 patients experiencing Grade 3 toxicity, SBRT was given after previous radiation. Conclusion: The results indicate SBRT to be an effective measure to achieve local control in spinal metastases. Toxicity of treatment was rare, including those previously irradiated. Our results appear comparable to previous reports analyzing spine SBRT. Further research is needed to determine optimum dose and fractionation to further improve local control and prevent toxicity.

    Background Differentiating melanoma metastasis from benign cutaneous lesions currently requires biopsy or costly imaging, such as positron emission tomography scans. Melanoma metastases have been observed to be subjectively warmer than similarly appearing benign lesions. We hypothesized that infrared (IR) thermography would be sensitive and specific in differentiating palpable melanoma metastases from benign lesions. Materials and methods Seventy-four patients (36 females and 38 males) had 251 palpable lesions imaged for this pilot study. Diagnosis was determined using pathologic confirmation or clinical diagnosis. Lesions were divided into size strata for analysis: 0–5, >5–15, >15–30, and >30 mm. Images were scored on a scale from −1 (colder than the surrounding tissue) to +3 (significantly hotter than the surrounding tissue). Sensitivity and specificity were calculated for each stratum. Logistical challenges were scored. Results IR imaging was able to determine the malignancy of small (0–5 mm) lesions with a sensitivity of 39% and specificity of 100%. For lesions >5–15 mm, sensitivity was 58% and specificity 98%. For lesions >15–30 mm, sensitivity was 95% and specificity 100%, and for lesions >30 mm, sensitivity was 78% and specificity 89%. The positive predictive value was 88%–100% across all strata, and the negative predictive value was 95% for >15–30 mm lesions and 80% for >30 mm lesions. Conclusions Malignant lesions >15 mm were differentiated from benign lesions with excellent sensitivity and specificity. IR imaging was well tolerated and feasible in a clinic setting. This pilot study shows promise in the use of thermography for the diagnosis of malignant melanoma with further potential as a noninvasive tool to follow tumor responses to systemic therapies.

    There is substantial and growing interest in the use of local therapies to treat patients with metastatic cancer, especially those deemed to have "oligometastatic" disease. Much of the literature to date consists of reports on metastasectomy for liver and lung metastases. Non-surgical minimally or non-invasive treatments including thermal ablation, irreversible electroporation, and high-dose radiation therapy (stereotactic ablative radiation therapy) can also be used in the treatment of primary and secondary tumors, including in the treatment of liver metastases. In this review, we discuss the rationale for using these ablative treatments in the treatment of liver metastases including similarities and differences between them. PMID:25416314

    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical significance of IPN and SPCM detected at the primary staging in CRC. Study I was a systematic review of published studies on IPN in CRC focusing on the prevalence and radiological characteristics of IPN proving to be malignant. This knowledge would be of value in management strategies for IPN. On average 9% of all patients staged with a thoracic CT had IPN, however, the prevalence varied significantly between patients series. This was mainly attributed to varying/lacking definitions on IPN and variable radiological expertise in the assessment of the scans. Data were too inconsistently reported in the case series for a robust statement to be made on potential radiological characteristics suggestive of malignancy in IPN. Lymph node metastasis was the most common clinicopathological finding associated with malignancy of IPN. In conclusion, one patient of every 100 scanned patients had an IPN proving to a SPCM at follow-up, but we found no evidence that IPN should result in intensified diagnostic work-up besides routine follow-up for CRC. Study II was an analysis of the

    Myasthenia gravis (MG) is an autoimmune disease. Approximately 15% of patients with MG have thymoma. Approximately 30% to 40% of them are invasive. A 26-year-old man was admitted with cough and difficulty breathing. He had transsternal thymectomy resulting from MG accompanied by thymoma 6 years previously. Thorax computerized tomography (CT) scans showed metastases to the extra-mediastinum. Diagnosis of invasive thymoma was made by CT-guided biopsy. A PAC regimen (cisplatin, doxorubicin, cyclophosphamide) and radiotherapy were added to MG treatment. Ten months later, he presented again with headache, weakness, and difficulty swallowing. We determined that he had intracranial multiple metastases. He was hospitalized. Cerebral multiple metastases were evaluated as inoperable. However, he died of transtentorial herniation after 1 month. This MG case accompanied by invasive thymoma with multiple intracranial metastases is discussed. PMID:19078711

    Isolated ovarian metastases from colorectal cancer (CRC) are rare disease presenting in approximately 3% of all patients undergoing colorectal resection. Most reports describe an open approach to the disease, but we report a case isolated ovarian metastases from CRC managed completely by robotic technique. A 54-year-old female, with a family history of CRC, was admitted for rectosigmoid junction cancer. Computed tomography scan demonstrated in rectosigmoid tumor and pelvic mass, presumed as teratoma. Robotic surgery discovered a 10-cm encapsulated tumor, attached to the left ovary, with no macroscopic peritoneal involvement. The pathologic diagnosis of the resected pelvic mass, ovarian metastases from CRC. Robotic anterior resection was performed. Operative time was lasted 165 min, considering 25 min for robotic system set up. This is the first report to describe robot-assisted anterior resection and oophorectomy in patient with isolated ovarian metastases from rectosigmoid junction cancer. PMID:25598608

    The use of 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in the evaluation and management of patients with malignancy continues to increase. However, its role in the identification of bone metastases is far from clear. FDG has the advantage of demonstrating all metastatic sites, and in the skeleton it is assumed that its uptake is directly into tumor cells. It is probable that for breast and lung carcinoma, FDG-PET has similar sensitivity, although poorer specificity, when compared with the isotope bone scan, although there is conflicting evidence, with several articles suggesting that it is less sensitive than conventional imaging in breast cancer. There is convincing evidence that for prostate cancer, FDG-PET is less sensitive than the bone scan and this may be tumor specific. There is very little data relating to lymphoma, but FDG-PET seems to perform better than the bone scan. There is an increasing body of evidence relating to the valuable role of FDG-PET in myeloma, where it is clearly better than the bone scan, presumably because FDG is identifying marrow-based disease at an early stage. There are, however, several other important variables that should be considered. The morphology of the metastasis itself appears to be relevant. At least in breast cancer, different patterns of FDG uptake have been shown in sclerotic, lytic, or lesions with a mixed pattern, Furthermore, the precise localization of a metastasis in the skeleton may be important with regard to the extent of the metabolic response induced. Previous treatment is highly relevant and it has been found that although the majority of untreated bone metastases are positive on PET scans and have a lytic pattern on computed tomography (CT), after treatment, incongruent CT-positive/PET-negative lesions are significantly more prevalent and generally are blastic, which presumably reflects a direct effect of treatment. Finally, the aggressiveness of the tumor itself may be relevant

    Purpose: To investigate the dosimetry and outcomes of patients undergoing stereotactic body radiotherapy (SBRT) for metastases to the adrenal glands. Methods and Materials: At University of Rochester, patients have been undergoing SBRT for limited metastases since 2001. We retrospectively reviewed 30 patients who had undergone SBRT for adrenal metastases from various primary sites, including lung (n = 20), liver (n = 3), breast (n = 3), melanoma (n = 1), pancreas (n = 1), head and neck (n = 1), and unknown primary (n = 1). Results: Of the 30 patients, 14 with five or fewer metastatic lesions (including adrenal) underwent SBRT, with the intent of controlling all known sites of metastatic disease, and 16 underwent SBRT for palliation or prophylactic palliation of bulky adrenal metastases. The prescribed dose ranged from 16 Gy in 4 fractions to 50 Gy in 10 fractions. The median dose was 40 Gy. Of the 30 patients, 24 had >3 months of follow-up with serial computed tomography. Of these 24 patients, 1 achieved a complete response, 15 achieved a partial response, 4 had stable disease, and 4 developed progressive disease. No patient developed symptomatic progression of their adrenal metastases. The 1-year survival, local control, and distant control rate was 44%, 55%, and 13%, respectively. No patient developed Radiation Therapy Oncology Group Grade 2 or greater toxicity. Conclusion: SBRT for adrenal metastases is well tolerated. Most patients developed widespread metastases shortly after treatment. Local control was poor, although this was a patient population selected for adverse risk factors, such as bulky disease. Additional studies are needed to determine the efficacy of SBRT for oligometastatic adrenal metastases, given the propensity of these patients to develop further disease progression.

    Lung adenocarcinoma often makes metastasis to the brain, liver, kidneys, bone, bone marrow and adrenal glands. It can also make metastasis to other parts of the body rarely for example eye, nose, parotid gland and paranasal sinus. We did not encounter with combined ocular bulbus and the maxillary sinus metastases of lung cancer in the accessible literature. In this case report, a patient who was combined ocular bulbus and the maxillary sinus metastases of lung adenocarcinoma will be discussed. PMID:26928715

    Purpose: To evaluate the outcomes after a single stereotactic radiosurgery procedure for the care of patients with 4 or more intracranial metastases. Methods and Materials: Two hundred five patients with primary malignancies, including non-small-cell lung carcinoma (42%), breast carcinoma (23%), melanoma (17%), renal cell carcinoma (6%), colon cancer (3%), and others (10%) underwent gamma knife radiosurgery for 4 or more intracranial metastases at one time. The median number of brain metastases was 5 (range, 4-18) with a median total treatment volume of 6.8 cc (range, 0.6-51.0 cc). Radiosurgery was used as sole management (17% of patients), or in combination with whole brain radiotherapy (46%) or after failure of whole brain radiotherapy (38%). The median marginal radiosurgery dose was 16 Gy (range, 12-20 Gy). The mean follow-up was 8 months. Results: The median overall survival after radiosurgery for all patients was 8 months. The 1-year local control rate was 71%, and the median time to progressive/new brain metastases was 9 months. Using the Radiation Therapy Oncology Group recursive partitioning analysis (RPA) classification system, the median overall survivals for RPA classes I, II, and III were 18, 9, and 3 months, respectively (p < 0.00001). Multivariate analysis revealed total treatment volume, age, RPA classification, and marginal dose as significant prognostic factors. The number of metastases was not statistically significant (p 0.333). Conclusion: Radiosurgery seems to provide survival benefit for patients with 4 or more intracranial metastases. Because total treatment volume was the most significant predictor of survival, the total volume of brain metastases, rather than the number of metastases, should be considered in identifying appropriate radiosurgery candidates.

    An increase in the incidence of breast cancer patients with brain metastases has been observed over the last years, mainly because the recent development of new drugs including therapies targeting HER2 (human epidermal growth factor receptor 2) resulted in an increased survival of these patients. With HER2+ patients living longer and the well-known neurotropism of HER2+ tumour cells, the resulting high incidence of brain metastases is not really surprising. Moreover, brain metastases more often occur within a context of existing extracranial metastases. These need to be treated at the same time in order to favourably impact patients' survival. Consequently, the management of breast cancer patients with brain metastases clearly relies on a multidisciplinary approach, including systemic treatment. A working group including neuro-oncologists, neurosurgeons, radiation oncologists and oncologists was created in order to provide French national guidelines for the management of brain metastases within the "Association des neuro-oncologues d'expression française" (ANOCEF). The recommendations regarding the systemic treatment in breast cancer patients are reported here including key features of their management. PMID:25662600

    Brain metastasis from gestational trophoblastic neoplasia (GTN) is rare with about 222 cases documented in the literature and an incidence of about 11% in living GTN patients. Brain metastasis from GTN was part of a disseminated disease in 90% of patients, single metastases in the brain - 80% and located in the cerebrum - 90%. Brain metastasis was the only manifestation of metastatic GTN in 11.3% of patients, appeared synchronously with metastatic GTN in other sites of the body - 30.6% and was diagnosed from 0.3 to 60 months after diagnosis of metastatic GTN in other sites (most often in the lung) - 58.1%. Overall, 83.9% of patients with brain metastases from GTN had also lung metastases from GTN. Brain metastases from GTN showed a greater tendency to be hemorrhagic compared to brain metastases from other primaries. In patients with brain metastases from GTN, the best outcome was achieved with multimodal therapy including craniotomy, whole brain radiotherapy, and EP-EMA or EMA-CO chemotherapy. Nonetheless, brain metastasis from GTN is a grave disease with a median survival time from diagnosis of brain metastasis of about 12 months. PMID:25118474

    The clinical management/understanding of brain metastases (BM) has changed substantially in the last 5 years, with key advances and clinical trials highlighted in this review. Several of these changes stem from improvements in systemic therapy, which have led to better systemic control and longer overall patient survival, associated with increased time at risk for developing BM. Development of systemic therapies capable of preventing BM and controlling both intracranial and extracranial disease once BM are diagnosed is paramount. The increase in use of stereotactic radiosurgery alone for many patients with multiple BM is an outgrowth of the desire to employ treatments focused on local control while minimizing cognitive effects associated with whole brain radiotherapy. Complications from BM and their treatment must be considered in comprehensive patient management, especially with greater awareness that the majority of patients do not die from their BM. Being aware of significant heterogeneity in prognosis and therapeutic options for patients with BM is crucial for appropriate management, with greater attention to developing individual patient treatment plans based on predicted outcomes; in this context, recent prognostic models of survival have been extensively revised to incorporate molecular markers unique to different primary cancers.

    Image-guided tumor ablation techniques have significantly broadened the treatment possibilities for primary and secondary hepatic malignancies. A new ablation technique, irreversible electroporation (IRE), was recently added to the treatment armamentarium. As opposed to thermal ablation, cell death with IRE is primarily induced using electrical energy: electrical pulses disrupt the cellular membrane integrity, resulting in cell death while sparing the extracellular matrix of sensitive structures such as the bile ducts, blood vessels, and bowel wall. The preservation of these structures makes IRE attractive for colorectal liver metastases (CRLM) that are unsuitable for resection and thermal ablation owing to their anatomical location. This review discusses different technical and practical issues of IRE for CRLM: the indications, patient preparations, procedural steps, and different "tricks of the trade" used to improve safety and efficacy of IRE. Imaging characteristics and early efficacy results are presented. Much is still unknown about the exact mechanism of cell death and about factors playing a crucial role in the extent of cell death. At this time, IRE for CRLM should only be reserved for small tumors that are truly unsuitable for resection or thermal ablation because of abutment of the portal triad or the venous pedicles.

    Summary In spite of advancement in science, molecular medicine and target therapies, surgical treatment of metastases using different techniques, from selective neck dissection to extended radical neck dissections, form a major part in the management of neck metastases. This is due to the fact that, so far, there is no treatment more effective for resectable neck metastases, than surgery. Since most head and neck cancer patients die due to loco-regional progression of disease, and a very large majority of them do not live long enough to develop distant metastases, the status of neck lymph nodes remains the single most important prognostic factor, in these cases. In the 100 years since George Washington Crile described Radical Neck Dissection, we now have a much better understanding of the biological and clinical behaviour of neck metastases. This has ultimately led to the conservative approaches of selective neck dissections depending on the primary site of the tumour, type of tumour and the characteristic features of the metastases themselves. A search of the literature on neck lymph nodes and neck dissections, on the internet and in old publications, not available in the electronic media, has been carried out. Using this as the basis, we arranged, in sequence, the dates of various landmarks in the treatment of head and neck cancer related to neck dissections to emphasize the overall process of evolution of neck dissection thereby showing how the field of head and neck surgery has travelled a long way from radical neck dissection to its modifications and further to selective neck dissections and sentinel node biopsies. The present understanding of the patterns of neck metastases enables us not only to adequately treat the neck metastases, but also to diagnose metastases from unknown primaries. Therefore, depending on the site of the primary tumour, it is now easy to predict the most probable route of metastatic spread and vice versa. This has enabled us to adopt

    The incidence of brain metastases is increasing because of the use of new therapeutic agents, which allow an improvement of overall survival, but with only a poor penetration into the central nervous system brain barriers. The management of brain metastases has changed due to a better knowledge of immunohistochemical data and molecular biological data, the development of new surgical, radiotherapeutic approaches and improvement of systemic treatments. Most of the time, the prognosis is still limited to several months, nevertheless, prolonged survival may be now observed in some sub-groups of patients. The main prognostic factors include the type and subtype of the primitive, age, general status of the patient, number and location of brain metastases, extracerebral disease. The multidisciplinary discussion should take into account all of these parameters. We should notice also that treatments including surgery or radiotherapy may be proposed in a symptomatic goal in advanced phases of the disease underlying the multidisciplinary approach until late in the evolution of the disease. This article reports on the ANOCEF (French neuro-oncology association) guidelines. The management of brain metastases of breast cancers and lung cancers are discussed in the same chapter, while the management of melanoma brain metastases is reported in a separate chapter due to different responses to the brain radiotherapy.

    Determining the evolutionary history of metastases is a key problem in cancer biology. Several recent studies have presented inferences regarding the origin of metastases based on phylogenies of cancer lineages. Many of these studies have concluded that the observed monophyly of metastatic subclones favored metastasis-to-metastasis spread ("a metastatic cascade" rather than parallel metastases from the primary tumor). In this article, we argue that identifying a monophyletic clade of metastatic subclones does not provide sufficient evidence to unequivocally establish a history of metastatic cascades. In the absence of a complete phylogeny of the subclones within the primary tumor, a scenario of parallel metastatic events from the primary tumor is an equally plausible interpretation. Future phylogenetic studies on the origin of metastases should obtain a complete phylogeny of subclones within the primary tumor. This complete phylogeny may be obtainable by ultra-deep sequencing and phasing of large sections or by targeted sequencing of many small, spatially heterogeneous sections, followed by phylogenetic reconstruction using well-established molecular evolutionary models. In addition to resolving the evolutionary history of metastases, a complete phylogeny of subclones within the primary tumor facilitates the identification of driver mutations by application of phylogeny-based tests of natural selection.

    The introduction of PSA screening has led to confirming a shift towards an earlier pathological stage in the diagnosis of prostate cancer. Consequently, the proportion of detecting early stage prostate cancer has clearly been increasing. On the other hand, progressive cancers in the form of distant metastases and locally advanced ones that have been confirmed at the initial diagnosis exhibit a constant rate. In addition, there have been a lot of cases where hormonal resistance was acquired during hormonal therapy which resulted in advanced metastases of the prostate. Prostate cancer has a tendency to be metastatic to bones. Combining the fact that the survival period of patients undergoing treatment is prolonged after metastases, the length of suffering caused by complications, such as ostealgia, pathological fracture and myelopathy, becomes an issue in which QOL and ADL of the patient are sacrificed for a long time. As for treatment of prostate cancer with metastases, a palliative treatment is common in the clinical scene. However, we can extend a life prognosis with use of radiotherapy and surgical treatment in addition to the palliative treatment at an appropriate time. It appears that a combination of new chemotherapy and hormonal therapy will be promising. In the future, we believe that the appearance of new anticancer drugs, endocrine therapies, bisphosphonates and strontium treatment could be used as a part of the treatment strategy for prostate cancer with bone metastases.

    In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression). Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach. PMID:26237068

    Brain metastasis from cervical carcinoma is rare with only about 100 cases documented in the literature and an incidence among cervical carcinoma patients of 0.6%. The median interval between diagnosis of cervical carcinoma and brain metastases is 18 months. The brain can be the only site of distant metastasis of cervical carcinoma ("isolated brain metastases") (46.8%) or brain metastasis can be part of a disseminated cervical carcinoma involving also other sites of the body (53.2%). Brain metastasis of cervical carcinoma affects most often the cerebrum (73%) and can be either single (one metastasis) (50.6%) or multiple (> or = two metastases) (49.4%). Treatment of brain metastases has evolved over the years from whole brain radiotherapy (WBRT) alone to multimodal therapy including surgical resection (craniotomy) or stereotactic radiosurgery (SRS) followed by WBRT +/- chemotherapy. The median overall survival after diagnosis of brain metastases is four months; however, a better survival is achieved with multimodal therapy (craniotomy followed by WBRT) compared to craniotomy alone or WBRT alone. The worst survival is observed in patients with no treatment. Although based on a very small number of patients, the best survival is noticed in patients having SRS either alone or in combination with other treatment modality. PMID:23327047

    Background The presence of tumor metastases in the mediastinum is one of the most important elements in determining the optimal treatment strategy in patients with non-small cell lung cancer. This review is aimed at examining the current strategies for investigating lymph node metastases corresponding to an “N2” classification delineated by The International Staging Committee of the International Association for the Study of Lung Cancer (IASLC). Methods Extensive review of the existing scientific literature related to the investigation of mediastinal lymph node metastases was undertaken in order to summarize and report current best practices. Conclusions N2 disease is very heterogeneous requiring multiple modalities for thorough investigation. New research is now focusing on better identifying, defining, and classifying lymph node metastases in the mediastinum. Molecular staging and sub-classifying mediastinal lymph node metastases are being actively researched in order to provide better prognostic value and to optimize treatment strategies. Non-invasive imaging, such as PET/CT and minimally invasive techniques such as endobronchial and endoscopic ultrasound guided biopsy, are now the lead investigative methods in evaluating the mediastinum for metastatic presence.

    Although the frontiers of liver resection for colorectal liver metastases have broadened in recent decades, approximately 75% of these patients present with unresectable metastases at the time of their diagnosis. In the past, these patients underwent only palliative treatment, without the chance of a cure. In the previous two decades, several therapeutic strategies have been developed that render resectable those metastases that were initially unresectable, thus offering the chance of long-term survival and even a cure to these patients. The oncosurgical modalities that are available include liver resection following portal vein ligation/embolization, “two-stage” liver resection, one-stage ultrasonically guided liver resection, hepatectomy following conversion chemotherapy, and liver resection combined with thermal ablation. Moreover, in recent years, certain authors have recommended the revisiting of the concept of liver transplantation in highly selected patients with unresectable colorectal liver metastases and favorable prognostic factors. By employing such therapies, the number of patients with colorectal liver metastases who undergo a potentially curative treatment could increase to 40%. The safety profile of these approaches is acceptable (morbidity rates as high as 45%, mortality rates of less than 5%). Furthermore, the 5-year survival rates (approximately 30%) are significantly increased over those that were achieved with palliative treatment. PMID:23082042

    Testicular lymphangiography was performed before retroperitoneal lymph node dissection in 20 patients with testicular tumor. The clinical value of testicular lymphangiography in the diagnosis of retroperitoneal metastases was evaluated retrospectively in comparison with the findings obtained by retroperitoneal lymph node dissection. In 12 patients who had no metastasis in the primary lymph nodes of the testis, testicular lymphangiography showed the lymph vessels to be diverged into 2 to 6 vessels (mean: 3.5) at the level between L2 and L4, and 4 to 10 lymph nodes (mean: 6.2) at the level between L1 and L4 were filled with contrast medium. On the other hand, in 8 patients who had metastases in the primary lymph nodes, several abnormal findings were observed in both lymph vessels and nodes, i.e., discontinuity, extravasation of contrast medium, dilatation, displacement and reflux to the distal side in the lymph vessels, and decrease in number (less than 2), non-visualization, filling defect, displacement and contrastfilling in the contralateral side in lymph nodes. Three to 5 of these abnormal findings were usually found in each case. The extravasation of contrast medium was not a finding specific to cases with lymph node metastases, because it was also found in a few cases without metastases. Testicular lymphangiography is a valuable method to detect primary lymph node metastases from testicular tumor. However, the combination of testicular and foot lymphangiography is imperative to demonstrate wide spread lymph node involvement in the retroperitoneum. PMID:6528843

However, additional lesions are often detected on high-resolution SRS-planning MRI. We investigated pre-treatment clinical characteristics that are associated with finding additional metastases at SRS. Patients treated with SRS for brain metastases between the years of 2009-2014 comprised the study cohort. All patients underwent frame-fixed, 1 mm thick MRI on the day of SRS. Patient, tumor, and treatment characteristics were analyzed for an association with increase in number of metastases identified on SRS-planning MRI. 289 consecutive SRS cases were analyzed. 725 metastases were identified on pre-treatment MRI and 1062 metastases were identified on SRS-planning MRI. An increase in the number of metastases occurred in 34 % of the cases. On univariate analysis, more than four metastases and the diameter of the largest lesion were significantly associated with an increase in number of metastases on SRS-planning MRI. When stratified by the diameter of the largest lesion into <2, 2-3, or ≥3 cm, additional metastases were identified in 37, 29, and 18 %, respectively. While this increase in the number of metastases is largely due to the difference in imaging technique, the number and size of the metastases were also associated with finding additional lesions. These clinical factors may be considered when determining treatment options for brain metastases. PMID:26966096

    We describe three women with cerebral metastases who presented following treatment for ovarian cancer. In all three cases the primary tumor underwent complete remission following cytoreductive surgery and adjuvant platinum-based combination chemotherapy. Cerebral metastases occurred at 18, 19, and 25 months following initial diagnosis of ovarian carcinoma. These cerebral lesions were treated with carboplatin 400 mg/m2 as a single agent. In one case total resolution of a single cerebral metastasis was achieved. In the other two women a significant reduction in tumor mass occurred and one of these responded to repeat treatment on two occasions. Survival times from diagnosis of the cerebral lesions were 11, 16, and 25 months. The treatment afforded rapid subjective and objective relief, significantly improved survival times, and was associated with good quality of life. Carboplatin should be considered for the treatment of cerebral metastases for ovarian cancer. PMID:7959302

    Brain metastases in breast cancer develop for 24-32 months after the detection of the primary tumor. The study included patients with brain metastases who were divided into three groups: the first group--with early chemoradiotherapy (CRT) without induction chemotherapy (IC) by capecitabine; the second group--with delayed CRT with 4 or 8 courses of IC by capecitabine; the third group (a historical control) who received only whole brain radiation therapy. The median time to progression of intracranial metastases was 15.3, 12 and 5 months, respectively. The median time to the intracranial progression significantly less in the third group (5 months) compared with the first (15.3 months) (p = 0.0007) and the second (12 months) (p = 0.027) groups. The overall survival rate was 22.1, 15.1 and 6.8 months in three groups, respectively. PMID:26995988

    In contrast to most other neoplastic processes of bone, in our study osseous metastases from soft-tissue sarcomas (STS) were more reliably detected by radiography than by scintigraphy. The radiographic manifestations of 65 skeletal metastases in 23 patients with STS were reveiwed. Although most metastases (88%) were osteolytic, eight (12%) lesions were osteoblastic. The destructive patterns were geographic in 29%, moth-eaten in 55%, and permeative in 12% of the lesions. The axial skeleton was most commonly involved. In the long bones the diaphyses were the predominant sites of involvement. The bony cortex was frequently breached, with resultant soft-tissue swelling and pathologic fractures. Noteworthy features included subarticular location, involvement of the sarcoiliac joint, and an expansile appearance.

    Background Neuroendocrine tumors (NET) represent a therapeutically challenging and heterogeneous group of malignancies occurring throughout the body, but mainly in the gastrointestinal system. Purpose To describe magnetic resonance imaging (MRI)-guided laser ablation of NET liver metastases and assess its role within the current treatment options and methods. Material and Methods Two patients with NET tumor hepatic metastases were treated with MRI-guided interstitial laser ablation (LITT). Three tumors were treated. Clinical follow-up time was 10 years. Results Both patients were successfully treated. There were no local recurrences at the ablation site during the follow-up. Both patients had survived at 10-year follow-up. One patient is disease-free. Conclusion MRI-guided laser ablation can be used to treat NET tumor liver metastases but combination therapy and a rigorous follow-up schedule are recommended.

    While the use of targeted therapies, particularly radiosurgery, has broadened therapeutic options for CNS metastases, patients respond minimally and prognosis remains poor. The inability of many systemic chemotherapeutic agents to penetrate the blood-brain barrier (BBB) has limited their use and allowed brain metastases to become a burgeoning clinical challenge. Adequate preclinical models that appropriately mimic the metastatic process, the BBB, and blood-tumor barriers (BTB) are needed to better evaluate therapies that have the ability to enhance delivery through or penetrate into these barriers and to understand the mechanisms of resistance to therapy. The heterogeneity among and within different solid tumors and subtypes of solid tumors further adds to the difficulties in determining the most appropriate treatment approaches and methods of laboratory and clinical studies. This review article discusses therapies focused on prevention and treatment of CNS metastases, particularly regarding the BBB, and the challenges and opportunities these therapies present.

    2010-01-01

    Abstract Bone scintigraphy augmented with radiographs or cross-sectional imaging, such as computed tomography (CT) or magnetic resonance imaging (MRI), has remained the commonest method to diagnose and follow up skeletal metastases. However, bone scintigraphy is associated with relatively poor spatial resolution, limited diagnostic specificity and reduced sensitivity for bone marrow disease. It also shows limited diagnostic accuracy in assessing response to therapy in a clinically useful time period. With the advent of hybrid positron emission tomography (PET)/CT scanners there has been an increasing interest in using various PET tracers to evaluate skeletal disease including [18F]fluoride (NaF) as a bone-specific tracer and [18F]fluorodeoxyglucose and [18F]choline as tumour-specific tracers. There is also early work exploring the receptor status of skeletal metastases with somatostatin receptor analogues. This review describes the potential utility of these tracers in the assessment of skeletal metastases. PMID:20663736

    Bone metastases are a process originally proposed as the "seed and soil theory" in the eighteenth century. Tumor cell disseminating from patients with breast or prostate cancer typically use the bony environment to grow outside the primary tumor location. The severe clinical consequences of bone metastasis such as pain, fractures, and hypercalcemia result from a serious misbalance of bone turnover. Most bone metastases cause catabolic changes of bone turnover. The severity of bone resorption is associated with tumor growth, suggesting the existence of a vicious cycle that needs to be interrupted. Osteoblastic metastasis showing signs of osteosclerotic lesions are observed in prostate cancer. Understanding the pathophysiology of bone metastases and their detrimental consequence provide the scientific basis for therapeutic interventions at various levels including homing of tumors to bone, survival and growth of the tumor cell in the bone niche, and the mechanisms causing bone destruction.

    We present a rare case of intrahepatic cholangiocarcinoma (ICC) with multiple skeletal muscle metastases. The patient was a 55-year-old Asian woman presenting with abdominal pain; abdominal and pelvic computed tomography and magnetic resonance cholangiopancreatography revealed an unresectable ICC with hepatic metastasis and metastastatic lymphadenopathy in the porto-caval area. After 3 mo of treatment with palliative radiotherapy and chemotherapy, magnetic resonance imaging of the thoracolumbar spine detected right psoas muscle and paraspinous muscle metastases. We performed an ultrasound-guided percutaneous fine-needle biopsy that confirmed a similar pattern of poorly differentiated adenocarcinoma. The patient treated with palliative chemotherapy and achieved 10 mo of survival. Here we report the first case quickly spread to multiple sites of muscle even though the three-month treatment, compare to the other cases reported muscle metastases at diagnosis. PMID:25684968

    Hepatic metastases (HM) are amongst the most important prognostic factors in patient survival from colorectal cancer. The diagnostic imaging techniques for accurate detection and characterization of colorectal metastases are therefore vital. In a review of the literature, MRI showed the highest sensitivity for detection of HM lesions < 1 cm, but the amount of MR scanners is insufficient. Contrast-enhanced ultrasound and computed tomography have similar sensitivity for detection of HM, but each method also have limitation such as operator dependency or enhanced risk of cancer due to ionizing radiation.

    Objectives This study aimed to develop a scoring system to predict the survival time of patients with bone metastases after radiation therapy (RT). The scoring system can guide physicians to a better selection of appropriate treatment regimens. Materials and Methods The medical records of 125 patients with bone metastases treated with RT between January 2007 and September 2010 were reviewed retrospectively. Fifteen potential prognostic factors were investigated: sex, age, Karnofsky performance score (KPS), type of primary tumor, resection of tumor before bone metastases, interval between primary tumor diagnosis and diagnosis of bone metastases, Carcinoembryonic Antigen(CEA), lung metastases before bone metastases, liver metastases before bone metastases, brain metastases before bone metastases, stage, T, N, M, and degree of cellular differentiation. Results In an univariate analysis, 10 factors were significantly associated with survival time after bone metastasis: sex, KPS, breast cancer, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, CEA, lung metastases before bone metastases, T-staging, and differentiation. In a multivariate analysis, 7 factors were found to be significant: sex, KPS, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, T-staging, and differentiation. The median survival of all patients with bone metastases after RT was 14.1 months. There were significant differences in the median survival of patients with bone metastases after RT of 4.9 months, 10.5 months, and 29.7 months in groups 1, 2, and 3, respectively (P<0.001). Conclusion According to this scoring system, the survival time of patients after bone metastasis can be estimated. PMID:27438606

    ABSTRACT Objective: The present study proposes to present the importance of perioperative therapeutic management in survival prolongation and the quality of life for patients that have undergone surgery for cerebral metastases secondary to pulmonary tumors. Method: During 2001-2009, 40 patients with ages between 43-74 years have been diagnosed in our clinic with pulmonary tumor and cerebral metastases. The patients presented single cerebral lesion (excepting one patient with 2 cerebral metastases) and pulmonary tumor. Intracranial pressure (ICP) was high in all cases. All patients have undergone operation with general anesthesia. Results:For all patients the reduction of ICP and keeping an optimal CPP (cerebral perfusion pressure) was pursued. In 38 cases, general anesthesia was performed with Sevoflurane and opioids (fentanyl, remifentanyl, sufentanyl) and in 2 cases the TIVA (total intravenous anesthesia) technique was used with propofol and remifentanyl. 14 of the patients required intraoperative depletive treatment through administering mannitol 20%. 37 patients (92%) have been discharged with improved neurological condition without showing signs of intracranial hypertension, convulsive seizures and with partially or totally remitted hemiparesis and one patient had worse postoperative neurological status. Conclusion:Pulmonary tumor with cerebral metastases represent an important cause for death rate. To solve secondary cerebral lesions, the perioperative management must include assesment and choosing an anesthesia technique with a proper intraoperative management. PMID:21977115

    Metastasis to the brain is a leading cause of cancer mortality. The current diagnostic method of gadolinium-enhanced MRI is sensitive only to larger tumors, when therapeutic options are limited. Earlier detection of brain metastases is critical for improved treatment. We have developed a targeted MRI contrast agent based on microparticles of iron oxide that enables imaging of endothelial vascular cell adhesion molecule-1 (VCAM-1). Our objectives here were to determine whether VCAM-1 is up-regulated on vessels associated with brain metastases, and if so, whether VCAM-1-targeted MRI enables early detection of these tumors. Early up-regulation of cerebrovascular VCAM-1 expression was evident on tumor-associated vessels in two separate murine models of brain metastasis. Metastases were detectable in vivo using VCAM-1-targeted MRI 5 d after induction (<1,000 cells). At clinical imaging resolutions, this finding is likely to translate to detection at tumor volumes two to three orders of magnitude smaller (0.3-3 × 10(5) cells) than those volumes detectable clinically (10(7)-10(8) cells). VCAM-1 expression detected by MRI increased significantly (P < 0.0001) with tumor progression, and tumors showed no gadolinium enhancement. Importantly, expression of VCAM-1 was shown in human brain tissue containing both established metastases and micrometastases. Translation of this approach to the clinic could increase therapeutic options and change clinical management in a substantial number of cancer patients. PMID:22451897

    Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Src is involved in multiple processes of cancer metastasis; however, its significance in HCC is not well defined. In the present study, overexpression of Src phosphorylation (Y416) was observed in the highly metastatic MHCC97H cell line; additionally, through inhibition of Src kinase activation, HCC cell proliferation, migration, invasion and colony formation were significantly reduced in vitro. Tumour growth was not affected in the orthotopic xenograft HCC model, but the metastasic potential was inhibited as revealed by reduced lung metastasic foci after administration of saracatinib. Phosphorylation level of Src pathway signalling molecules, such as Src, FAK and Stat3, were also reduced in vitro and in vivo, as a result of the anti-metastasic effects caused by saracatinib treatment. In conclusion, we demonstrated the pro-metastasic role of Src in HCC, and further experiments suggest the use of the Src inhibitor in combination with cytotoxic agents and other anticancer treatments to improve HCC prognosis.

    Brain metastases impact on the survival of the patients, but on their quality of life as well. The objective of the management of these patients is then double. Currently, due to medical advances, survivals tend to improve, especially for some tumor subtypes. During the course of the disease, different neurological signs and symptoms can be observed according to the location, the number and the volume of the metastase(s). Patients and caregivers are especially worried about the loss of autonomy and cognitive impairments. A permanent dialogue, during the course of the disease, is mandatory, in order to adapt the management to the objectives determined by the patients and the medical team. These objectives may vary according to the objective response rates of the disease to anticancer therapies, according to the impact of the disease and its management in daily living. Anticancer therapies and supportive care must be appreciated according to their impact on the survival, on the preservation of the functional independence and the quality of life of the patient, on their abilities to preserve the neurological status and delay the apparition of new neurological signs and symptoms, and their adverse events. Supportive care, cognition and quality of life should be regularly evaluated and adapted according to the objectives of the management of brain metastases patients. Different approaches are described in this paper. PMID:25640218

    Cavitation in pulmonary metastases is thought to be uncommon. To date, few cases of pulmonary metastases originating from ovarian cancer and showing cavitation have been reported. We report a patient with multiple cavitation in pulmonary metastases from ovarian mucinous cystadenocarcinoma. A 28-year-old woman was admitted to our hospital presenting with cough and fever. The patient had undergone right ovariectomy for ovarian mucinous cystadenocarcinoma at the age of 23 years. Her chest radiograph on admission showed multiple cavities associated with infiltration in both lungs. Histological sections obtained by transbronchial lung biopsy revealed mucus-secreting adenocarcinoma, and a diagnosis of metastatic lung cancer from the ovary was made. Computed tomographic (CT) scans of the chest demonstrated various findings, including multiple thick-walled cavities, thin-walled cavities, air-space consolidations, ground glass opacities, and centrilobular nodular shadows formed by aspiration of the mucinous secretions. It is important to recognize that cavitation can occur in pulmonary metastases from ovarian cancer. PMID:11530393

    Benign metastasizing leiomyoma (BML) usually are situated in one organ, most often in lungs. BML patients typically have a history of uterine leiomyoma treated with hysterectomy, myomectomy or subtotal hysterectomy. The aim of the study was to present the case of a 53-year-old woman with triple location in the lungs, parametria and appendix. She had undergone a myomectomy 26 years earlier. In 2015, she was admitted to the surgical department because of abdominal pain, whereupon a cholecystectomy was performed. CT scans showed pelvic mass with pulmonary metastasis. Upon discharge the patient was referred to the Gynecology Clinic, where a laparotomy was performed. The intraoperative findings were: 1) uterus with multiple leiomyomas, 2) four tumors in the parametria, 3) tumor connected to the appendix. A subtotal hysterectomy, with a bilateral salpingo-oophorectomy, removal of the tumors from the parametria and appendectomy was performed. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining (strongly positive for estrogen receptors and SMA, while Ki67 was very low, below 1%). Upon postoperative recovery, the patient was referred to the Thoracic Surgery Department. During the thoracotomy, multiple nodes, surrounded by lung parenchyma, were revealed. Wedge resection was performed, for localized pulmonary lesions, and sent for pathological examination. The final pathological diagnosis was benign metastasizing leiomyomatosis. In conclusion, the triple location of BML could possibly be a result of a parallel different metastasizing mechanism, although it is impossible to exclude one mechanism, which may be the cause of the metastases in three locations.

    When liver metastases from colorectal carcinoma are detected, the surgeon must decide whether or not the patient is a candidate for resection. Even though long-term survival after resection is far from optimal, the relegation of patients to nonresective treatment means denying them the only chance for cure currently available. Better understanding of liver anatomy and improvement in resection techniques have decreased the morbidity and mortality. The RHM and the GITSG reports have better defined the prognostic factors for resections of colorectal liver metastases and allowed for a better understanding of the indications for resection. During the last decades, liver resection has been extended to older patients, patients with multiple liver lesions, and patients with larger solitary metastases. At the same time, anatomic rather than wedge resections are more common, and it is preferable to perform the colon and liver resection at different stages. The end result has been a marked increase in the number of hepatic resections performed for colorectal liver metastases during the last two decades. PMID:8031663

    Breast cancer brain metastases (BCBMs) are the second most frequent secondary central nervous system metastases following those associated with non-small-cell lung cancer. It is increasingly evident that BCBM arises as a function of the biology of the primary tumor and the metastatic niche, which combine to create a unique microenvironment in the brain impacting both metastatic colonization and therapeutic response. Clinical outcomes are improving for BCBM patients as a result of modern combinatorial therapies, challenging the traditionally nihilistic approach to this patient subgroup. This review will focus on the breast cancer subtypes with the highest incidence of BCBM-human epidermal growth factor receptor 2 (HER2)-positive breast cancer, and triple-negative (estrogen receptor [ER]-negative, progesterone receptor [PR]-negative, and HER2-negative) breast cancer (TNBC)-and will characterize differences in the clinical behavior of brain metastases that arise from these different subtypes. We will also highlight some of the recent preclinical studies that may shed light on the biological mechanisms and mediators underlying brain metastases. Finally, we will review published and current prospective trials of systemic therapies specifically for BCBM, including novel pathway-specific therapies. PMID:22888567

The aim of this study was to determine whether there was a difference in the lymphatic vessel density (LVD) when cutaneous metastasizing melanomas were compared with nonmetastasizing melanomas and nevi. Methods Ninety-five melanoma specimens (45 with lymph node metastasis, 50 nonmetastasizing) and 22 nevi specimens (7 compound, 5 intradermal, 4 blue, and 6 dysplastic) were investigated by immunostaining for the lymphatic endothelial marker D2-40. The quantification of lymphatics was conducted by computer-assisted morphometric analysis. Metastasizing and nonmetastasizing melanoma specimens were matched according to their thickness into three classes ≤2.0 mm, 2.01 – 4.0 mm, >4.0 mm. Results Metastasizing melanomas thick 2.01–4.0 mm and thicker than 4.0 mm, showed a significantly higher intratumoral and peritumoral LVD compared with nonmetastasizing melanomas (2.01–4.0 mm, p =0.006 and p =0.032, respectively; >4.0 mm, p =0.045 and p =0.026, respectively). No significant difference in intratumoral and peritumoral LVD was found between metastasizing and nonmetastasizing melanomas of thickness ≤2.0 mm. Metastasizing melanomas showed a significantly higher intratumoral LVD compared with compound, intradermal, blue and dysplastic nevi p <0.001, p =0.002, p =0.002 and p <0.001, respectively), and significantly higher peritumoral LVD compared with compound nevi (p=0.039). Total average LVD was significantly higher in metastasizing melanomas than in nonmetastasizing melanomas (p <0.001), compound, intradermal, blue and dysplastic nevi (p <0.001, p <0.001, p =0.001 and p <0.001, respectively). Conclusions This study shows higher LVD in metastasizing melanomas compared with nonmetastasizing melanomas and nevi. In melanomas with

    The external pH of solid tumors is acidic as a consequence of increased metabolism of glucose and poor perfusion. Acid pH has been shown to stimulate tumor cell invasion and metastasis in vitro and in cells before tail vein injection in vivo. The present study investigates whether inhibition of this tumor acidity will reduce the incidence of in vivo metastases. Here, we show that oral NaHCO3 selectively increased the pH of tumors and reduced the formation of spontaneous metastases in mouse models of metastatic breast cancer. This treatment regimen was shown to significantly increase the extracellular pH, but not the intracellular pH, of tumors by 31P magnetic resonance spectroscopy and the export of acid from growing tumors by fluorescence microscopy of tumors grown in window chambers. NaHCO3 therapy also reduced the rate of lymph node involvement, yet did not affect the levels of circulating tumor cells, suggesting that reduced organ metastases were not due to increased intravasation. In contrast, NaHCO3 therapy significantly reduced the formation of hepatic metastases following intrasplenic injection, suggesting that it did inhibit extravasation and colonization. In tail vein injections of alternative cancer models, bicarbonate had mixed results, inhibiting the formation of metastases from PC3M prostate cancer cells, but not those of B16 melanoma. Although the mechanism of this therapy is not known with certainty, low pH was shown to increase the release of active cathepsin B, an important matrix remodeling protease. PMID:19276390

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    Purpose/Objective(s): Radiation therapy can be used to treat uveal metastases with the goal of local control and improvement of quality of life. Proton therapy can be used to treat uveal tumors efficiently and with expectant minimization of normal tissue injury. Here, we report the use of proton beam therapy for the management of uveal metastases. Methods and Materials: A retrospective chart review was made of all patients with uveal metastases treated at our institution with proton therapy between June 2002 and June 2012. Patient and tumor characteristics, fractionation and dose schemes, local control, and toxicities are reported. Results: Ninety patients were identified. Of those, 13 were excluded because of missing information. We report on 77 patients with 99 affected eyes with available data. Patients were 68% female, and the most common primary tumor was breast carcinoma (49%). The median age at diagnosis of uveal metastasis was 57.9 years. Serous retinal detachment was seen in 38% of treated eyes. The median follow-up time was 7.7 months. The median dose delivered to either eye was 20 Gy(relative biological effectiveness [RBE]) in 2 fractions. Local control was 94%. The median survival after diagnosis of uveal metastases was 12.3 months (95% confidence interval, 7.7-16.8). Death in all cases was secondary to systemic disease. Radiation vasculopathy, measured decreased visual acuity, or both was observed in 50% of evaluable treated eyes. The actuarial rate of radiation vasculopathy, measured decreased visual acuity, or both was 46% at 6 months and 73% at 1 year. The 6 eyes with documented local failure were successfully salvaged with retreatment. Conclusions: Proton therapy is an effective and efficient means of treating uveal metastases. Acutely, the majority of patients experience minor adverse effects. For longer-term survivors, the risk of retinal injury with vision loss increases significantly over the first year.

    Purpose. To determine the efficacy of celiac plexus block during thermoablation of liver metastases. Methods. Fifty-five consecutive patients underwent thermoablation therapy of liver tumors by laser-induced thermotherapy. Twenty-nine patients received a temporary celiac plexus block, 26 patients acted as control group. In both groups fentanyl and midazolam were administered intravenously upon request of the patient. The duration of the intervention, consumption of opiates, and individual pain sensations were documented. Results. No complications resulting from the celiac plexus block were recorded. Celiac plexus block significantly reduced the amount of pain medication used during thermoablation therapy of liver tumors (with block, 2.45 {mu}g fentanyl per kg body weight; without block, 3.58 {mu}g fentanyl per kg body weight, p < 0.05; midazolam consumption was not reduced) in patients with metastases {<=}5 mm from the liver capsule. For metastases farther away from the capsule no significant differences in opiate consumption were seen. Celiac plexus block reduced the time for thermoablation significantly (178 min versus 147 min, p < 0.05) no matter how far the metastases were from the liver capsule. Average time needed to set the block was 12 min (range 9-15 min); additional costs for the block were marginal. As expected (as pain medications were given according to individual patients' needs) pain indices did not differ significantly between the two groups. Conclusion. In patients with liver metastases {<=}5 mm from the liver capsule, celiac plexus block reduces the amount of opiates necessary, simplifying patient monitoring. In addition celiac plexus block reduces intervention time, with positive effects on overall workflow for all patients.

    Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized. PMID:27561800

    Intracranial metastases represent 7-17% of all brain tumors. Renal cell carcinoma, thyroid cancer, choriocarcinoma, melanoma, retinoblastoma, lung cancer and breast cancer have a propensity for producing hemorrhagic brain metastases. Leukemias have also been rarely reported to cause hemorrhagic brain metastases. We describe an 18-year-old girl diagnosed as acute lymphoblastic leukemia presenting with multiple hemorrhagic brain metastases. MRI demonstrated high signal intensity lesions on both T1- and T2-weighted images which were characteristic for extracellular methemoglobin and consistent with hemorrhagic metastases. PMID:15236125

    A comparative study has been realized to test the accuracy of ultrasonography and scintigraphy for detecting the presence of liver metastases in 305 patients with colorectal carcinomas. Presence or absence of hepatic metastases has been affirmed by laparotomy and biopsy. In the 47 cases with metastases, the sensitivity of ultrasonography was 93%, that of scintigraphy being 76%. In 258 cases without metastases the specificity of ultrasonography was 97%, that of scintigraphy being 92%. These results, confirmed by report in the published literature, show that ultrasonography should be the first examination for suspected hepatic metastases.

    Nephron-sparing laparoscopy is the standard surgical treatment for clinical T1a renal tumours. However, the laparoscopic technique brings in its specific oncological safety concerns. Seeding metastases are reported: peritoneal metastases, port-tract metastases, and (sub-) cutaneous metastases. The method of laparoscopic assisted renal mass cryoablation is marked by the fact that traumatic tumour tissue handling is unavoidable. This case report reviews the rare occasion of seeding metastases in the retroperitoneal space following laparoscopic cryoablation of a small renal mass. The primary tumour showed no focal recurrence as reported by histological examination. The combination of two events as harming the integrity of cancer tissue and gas-circulation leading to the development of metastases in the retroperitoneal cavity is discussed. The combination of iatrogenic harming cancer tissue integrity and CO2-circulation leads to metastases in the retroperitoneal cavity. Therefore, we recommend performing image-guided renal mass biopsies before considering cryoablative surgery. PMID:26425230

    Brain metastases are unusual from urethelial carcinoma of bladder and particularly the occurrence of leptomeningeal metastases is extremely rare, with few cases described in the literature. We present a case of a 45-year-old man with a rare brain metastases as the first metastatic manifestation secondary to urethelial carcinoma of bladder followed by leptomeningeal metastases without any other organ involvement. Eleven months after the diagnosis of high-grade urethelial carcinoma of bladder (T2N0M0), the patient was detected having brain metastases by MRI. FDG PET/CT images for the metastatic evaluation showed no abnormal FDG uptake elsewhere in the body except the brain. Histopathology examination from brain lesion demonstrated the cerebral lesion to be a metastatic urothelial carcinoma. Two months later, the patient was diagnosed to have leptomeningeal metastases by MRI. Our patient's condition gradually worsened, and he died 3 months after the diagnosis of leptomeningeal metastases. PMID:25043771

    Liver metastases from colorectal cancer (CRC) result in substantial morbidity and mortality. The primary treatment is systemic chemotherapy, and in selected patients, surgical resection; however, for patients who are not surgical candidates and/or fail systemic chemotherapy, liver-directed therapies are increasingly being utilized. Yttrium-90 (Y-90) microsphere therapy, also known as selective internal radiation therapy (SIRT) or radioembolization, has proven to be effective in terms of extending time to progression of disease and also providing survival benefit. This review focuses on the use of Y-90 microsphere therapy in the treatment of liver metastases from CRC, including a comprehensive review of published clinical trials and prospective studies conducted thus far. We review the methodology, outcomes, and side effects of Y-90 microsphere therapy for metastatic CRC. PMID:25120951

    We encountered a case of cutaneous metastases from colorectal carcinoma. A 63-year-old woman underwent laparoscopic-assisted ileocecal resection for cecal cancer. Computed tomography (CT) showed multiple liver metastases. The tumor was diagnosed as a well-differentiated adenocarcinoma and was staged as pSE, pN1, sH2, ly1, v1, CP0cM0, fStage Ⅳ. She was treated with 33 courses of the 5-fluorouracil, Leucovorin, and irinotecan (FOLFIRI) regimen and 15 courses of the 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6) plus bevacizumab regimen. Thirty-four months after resection, multiple cutaneous tumors were noted, predominantly on the lower abdomen, and we resected 2 of them. Histologically, the specimens were diagnosed as well-differentiated adenocarcinoma, which was similar to that of cecal carcinoma. After 1 course of regorafenib, she died 3 years after the primary surgical resection. PMID:26805285

    Occurring either synchronously or metachronously to the primary tumor, peritoneal metastases (PM) are diagnosed in 8 to 20 % of the patients with colorectal cancer (CRC). Prognosis of these patients appears to be worse than those with other sites of metastases. While systemic therapy has shown significant prolongation of survival in patients with stage IV colorectal cancer, the outcomes in the subset of patients with PM has been much inferior. Over the last 2 decades, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) have been effective in substantially prolonging survival in patients with colorectal PM and have the potential to cure certain patients as well. This article reviews the current evidence for CRS and HIPEC to treat colorectal PM as well as future research going on in this form of locoregional treatment. PMID:27065708

    We report a rare case of multiple pulmonary metastases with cavitation from gallbladder cancer. A 77-year-old woman was admitted to our hospital complaining of productive cough and exertional dyspnea. Chest X-ray film showed multiple nodular shadows with some cavitation. Computed tomography showed multiple cavities, up to 2 cm in diameter, as well as nodules, in bilateral lung fields. Under a survey of primary focus, the ultrasonographic test of the abdomen revealed a hypoechoic mass in the hepatic hilum. The patient died of respiratory failure. Autopsy findings revealed that that multiple lung tumors had metastasized from papillary adenocarcinoma of the gallbladder and that cavitation of the lung was formed by bronchioloectasis.

We report the case of a 44-year-old obese woman (BMI 45.5) who underwent surgery to remove uterine leiomyomata and then continued to take a drug containing the hormone estradiol for a period of 15 years. Computed tomography chest examinations revealed multiple size nodules of varying size in both lungs. Videothoracoscopy and right thoracotomy was performed, and a few nodules were enucleated from each lobe of the right lung. Postoperative histopathological examination revealed benign metastasizing leiomyoma staining positive for estrogen and progesterone receptors (ER+, PR+). Because of the hormonally dependent cell proliferation, the previously used hormonal drug was discontinued. Treatment with a gonadotropin-releasing hormone analog was included, yielding radiological stabilization of the lung lesions. PMID:27212984

    Primary intracranial myxofibrosarcoma is exceedingly rare, with less than 10 cases published. We present a case of a 23-year-old man with previous history of a primary low grade myxofibrosarcoma of the left parietal-occipital convexity resected in March 1999. He subsequently underwent several interventions for multiple local recurrent disease until March 2004. At that time, complete remission was documented. About 8 years later, in February 2012, the patient was admitted to the emergency room with refractory acute pulmonary oedema. On work up, sustained monomorphic ventricular tachycardia and hyperechoic myocardial mass with invasion of the right ventricular cavity were detected. Electrical cardioversion was unsuccessful and irreversible cardiac arrest followed. The autopsy confirmed multiple bilateral lung metastases, malignant pulmonary embolism and myocardial invasion by the primary tumour, with intracavitary cardiac thrombosis and absence of intracranial disease. To the best of our knowledge, this is the first report of extracranial metastases of this neoplasm. PMID:27013654

    Colorectal carcinoma is one of the most frequent cancers in Western societies with an incidence of around 700 per million people. About half of the patients develop metastases from the primary tumor and liver is the primary metastatic site. Improved survival rates after hepatectomy for metastatic colorectal cancer have been reported in the last few years and these may be the result of a variety of factors, such as advances in systemic chemotherapy, radiographic imaging techniques that permit more accurate determination of the extent and location of the metastatic burden, local ablation methods, and in surgical techniques of hepatic resection. These have led to a more aggressive approach towards liver metastatic disease, resulting in longer survival. The goal of this paper is to review the role of various forms of surgery in the treatment of hepatic metastases from colorectal cancer. PMID:21267397

    To determine the efficacy of radiofrequency (RF) ablation in neuroendocrine tumor (NET) liver metastases. A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eight studies were included (N = 301). Twenty-six percent of RF ablation procedures were percutaneous (n = 156), with the remainder conducted at surgery. Forty-eight percent of patients had a concomitant liver resection. Fifty-four percent of patients presented with symptoms, with 92% reporting symptom improvement following RF ablation (alone or in combination with surgery). The median duration of symptom improvement was 14-27 months. However, recurrence was common (63%-87%). RF ablation can provide symptomatic relief in NET liver metastases alone or in combination with surgery. PMID:25840836

    The best clinical treatment for spinal metastases requires an integrated approach with input from an interdisciplinary cancer team. The principle goals of treatment are maintenance or improvement in neurologic function and ambulation, spinal stability, durable tumor control, and pain relief. The past decade has witnessed an explosion of new technologies that have impacted our ability to reach these goals, such as separation surgery and minimally invasive spinal procedures. The biggest advance, however, has been the evolution of stereotactic radiosurgery that has demonstrated durable tumor control both when delivered as definitive therapy and as a postoperative adjuvant even for tumors considered markedly resistant to conventional external beam radiation. In this paper, we perform an update on the management of spinal metastases demonstrating the integration of these new technologies into a decision framework NOMS that assesses four basic aspects of a patient's spine disease: Neurologic, Oncologic, Mechanical Instability and Systemic disease.

    Primary sites of tumor are the focal triggers of cancers, yet it is the subsequent metastasis events that cause the majority of the morbidity and mortality. Metastatic tumor cells exhibit a phenotype that differs from that of the parent cells, as they represent a resistant, invasive subpopulation of the original tumor, may have acquired additional genetic or epigenetic alterations under exposure to prior chemotherapeutic or radiotherapeutic treatments, and reside in a microenvironment differing from that of its origin. This combination of resistant phenotype and distal location make tracking and treating metastases particularly challenging. In this review, we highlight some of the unique biological traits of metastasis, which in turn, inspire emerging strategies for targeted imaging of metastasized tumors and metastasis-directed delivery of therapeutics.

    Bladder cancer rarely presents clinically with a myelophthisic picture from diffuse bone marrow infiltration especially in the absence of detectable skeletal metastases. A 75-year old man presented with newly diagnosed urothelial cell carcinoma of the bladder. Pathology from transurethral resection of bladder tumor demonstrated muscle-invasive disease. Pre-therapy imaging including CT abdomen/pelvis, CXR and bone scan demonstrated liver lesions concerning for metastatic disease but no skeletal metastases. Labs were notable for isolated thrombocytopenia, hypercalcemia and acute kidney injury prompting hospitalization. Hematologic work-up including bone marrow aspiration and biopsy revealed diffuse infiltration of the bone marrow by urothelial cancer. The case illustrates the importance of fully investigating otherwise unexplained clinical findings in patients with clinically localized urothelial cancer prior to curative intent surgery.

    We retrospectively considered the validity of radiotherapy for patients with bone metastases from esophageal cancer. Eight patients have received radiotherapy in our hospital since 2007. The median age of the patients was 63 years, with 5 men and 3 women. Bone metastatic sites were 4 to the vertebrae, 3 to the ribs, 3 to the femur and 1 each to the humerus, ulna, and radius, respectively. All of the patients had other unresectable sites of metastasis. Radiotherapy reduced pain of 3 patients of PS 1 clearly. Median survival time from the start of radiation therapy was 50 days. When PS was relatively good, the possibility of easing pain and improving QOL was suggested by our data. There is a possibility that radiation therapy for patients with bone metastases from esophageal cancer can improve the QOL and alleviate pain. PMID:26805091

    Many management strategies exist for neuroendocrine liver metastases. These strategies range from surgery to ablation with various interventional radiology procedures, and include both regional and systemic therapy with diverse biological, cytotoxic, or targeted agents. A paucity of biological, molecular, and genomic information and an absence of data from rigorous trials limit the validity of many publications detailing management. This Review represents the views from an international conference, for which 15 expert working groups prepared evidence-based assessments addressing specific questions, and from which an independent jury derived final recommendations. The aim of the conference was to review the existing approaches to neuroendocrine liver metastases, assess the evidence on which management decisions were based, develop internationally acceptable recommendations for clinical practice (when evidence was available), and make recommendations for clinical and research endeavours. This report represents the final clinical statements and proposals for future research. PMID:24384494

    Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. PMID:26713674

    Purpose: Accurate segmentation and quantification of liver metastases on CT images are critical to surgery/radiation treatment planning and therapy response assessment. To date, there are no reliable methods to perform such segmentation automatically. In this work, the authors present a method for semiautomatic delineation of liver metastases on contrast-enhanced volumetric CT images. Methods: The first step is to manually place a seed region-of-interest (ROI) in the lesion on an image. This ROI will (1) serve as an internal marker and (2) assist in automatically identifying an external marker. With these two markers, lesion contour on the image can be accurately delineated using traditional watershed transformation. Density information will then be extracted from the segmented 2D lesion and help determine the 3D connected object that is a candidate of the lesion volume. The authors have developed a robust strategy to automatically determine internal and external markers for marker-controlled watershed segmentation. By manually placing a seed region-of-interest in the lesion to be delineated on a reference image, the method can automatically determine dual threshold values to approximately separate the lesion from its surrounding structures and refine the thresholds from the segmented lesion for the accurate segmentation of the lesion volume. This method was applied to 69 liver metastases (1.1–10.3 cm in diameter) from a total of 15 patients. An independent radiologist manually delineated all lesions and the resultant lesion volumes served as the “gold standard” for validation of the method’s accuracy. Results: The algorithm received a median overlap, overestimation ratio, and underestimation ratio of 82.3%, 6.0%, and 11.5%, respectively, and a median average boundary distance of 1.2 mm. Conclusions: Preliminary results have shown that volumes of liver metastases on contrast-enhanced CT images can be accurately estimated by a semiautomatic segmentation

    Metastasis of colorectal adenocarcinoma of the ovary is not an uncommon occurrence and ovarian metastases from colorectal carcinoma frequently mimic endometrioid and mucinous primary ovarian carcinoma. The clinical and pathologic features of metastatic colorectal adenocarcinoma involving the ovary is reviewed with particular focus on the diagnostic challenge of distinguishing these secondary ovarian tumors from primary ovarian neoplasm. Immunohistochemical stains that may be useful in the differential diagnosis of metastatic colorectal tumors to the ovary and primary ovarian tumors are detailed. PMID:21160859

    Transforming growth factor (TGF-β) derived from bone fuels melanoma bone metastases by inducing tumor secretion of pro-metastatic factors that act on bone cells to change the skeletal microenvironment. Halofuginone is a plant alkaloid derivative that blocks TGF-β signaling with antiangiogenic and antiproliferative properties. Here, we demonstrate for the first time that halofuginone therapy decreases development and progression of bone metastasis caused by melanoma cells through inhibition of TGF-β signaling. Halofuginone treatment of human melanoma cells inhibited cell proliferation, phosphorylation of SMAD proteins in response to TGF-β, and TGF-β-induced SMAD-driven transcription. In addition, halofuginone reduced expression of TGF-β target genes that enhance bone metastases, including PTHrP, CTGF, CXCR4, and IL11. Also, cell apoptosis was increased in response to halofuginone. In nude mice inoculated with 1205Lu melanoma cells, a preventive protocol with halofuginone inhibited bone metastasis. The beneficial effects of halofuginone treatment were comparable to those observed with other anti-TGF-β strategies, including systemic administration of SD208, a small molecule inhibitor of TGF-β receptor I kinase, or forced overexpression of Smad7, a negative regulator of TGF-β signaling. Furthermore, mice with established bone metastases treated with halofuginone had significantly less osteolysis than mice receiving placebo assessed by radiographys. Thus, halofuginone is also effective in reducing the progression of melanoma bone metastases. Moreover, halofuginone treatment reduced melanoma metastasis to the brain, showing the potential of this novel treatment against cancer metastasis. PMID:23002206

    Purpose: To assess the imaging and clinical outcomes of patients with single brainstem metastases treated with stereotactic radiosurgery (SRS). Materials and Methods: We retrospectively reviewed the data from patients with single brainstem metastases treated with SRS. Locoregional control and survival were calculated using the Kaplan-Meier method. Prognostic factors were assessed using a Cox proportional hazards model. Results: Between 1997 and 2007, 43 patients with single brainstem metastases were treated with SRS. The median age at treatment was 59 years, the median Karnofsky performance status was 80, and the median follow-up was 5.3 months. The median dose was 15 Gy (range, 9.6-24), and the median conformality and heterogeneity index was 1.7 and 1.9, respectively. The median survival was 5.8 months from the procedure date. Of the 33 patient with post-treatment imaging available, a complete radiographic response was achieved in 2 (4.7%), a partial response in 8 (18.6%), and stable disease in 23 (53.5%). The 1-year actuarial rate of local control, distant brain control, and overall survival was 85%, 38.3%, and 31.5%, respectively. Of the 43 patients, 8 (19%) died within 2 months of undergoing SRS, and 15 (36%) died within 3 months. On multivariate analysis, greater performance status (hazard ratio [HR], 0.95, p = .004), score index for radiosurgery (HR, 0.7; p = .004), graded prognostic assessment score (HR, 0.48; p = .003), and smaller tumor volume (HR, 1.23, p = .002) were associated with improved survival. No Grade 3 or 4 toxicities were observed. Conclusion: The results of our study have shown that SRS is a safe and effective local therapy for patients with brainstem metastases.

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    PurposeResection is the mainstay of management in patients with sarcoma lung metastases, but there is a limit to how many resections can be performed. Some patients with inoperable disease have small-volume lung metastases that are amenable to thermal ablation. We report our results after radiofrequency ablation (RFA).MethodsThis is a retrospective study of patients treated from 2007 to 2012 in whom the intention was to treat all sites of disease and who had a minimum CT follow-up of 4 months. Treatment was performed under general anesthesia/conscious sedation using cool-tip RFA. Follow-up CT scans were analyzed for local control. Primary tumor type, location, grade, disease-free interval, prior resection/chemotherapy, number and size of lung tumors, uni- or bilateral disease, complications, and overall and progression-free survival were recorded.ResultsTwenty-two patients [15 women; median age 48 (range 10–78) years] with 55 lung metastases were treated in 30 sessions. Mean and median tumor size and initial number were 0.9 cm and 0.7 (range 0.5–2) cm, and 2.5 and 1 (1–7) respectively. Median CT and clinical follow-up were 12 (4–54) and 20 (8–63) months, respectively. Primary local control rate was 52 of 55 (95 %). There were 2 of 30 (6.6 %) Common Terminology Criteria grade 3 complications with no long-term sequelae. Mean (median not reached) and 2- and 3-year overall survival were 51 months, and 94 and 85 %. Median and 1- and 2-year progression-free survival were 12 months, and 53 and 23 %. Prior disease-free interval was the only significant factor to affect overall survival.ConclusionRFA is a safe and effective treatment for patients with small-volume sarcoma metastases.

    Locoregional therapies for colorectal liver metastases complement systemic therapy by providing an opportunity for local control of hepatic spread. The armamentarium for liver-directed therapy includes ablative therapies, embolization, and stereotactic body radiation therapy. At this time, prospective studies comparing these modalities are limited and decision-making relies on a multidisciplinary approach for optimal patient management. Herein, we describe multiple therapeutic non-surgical procedures and an overview of the results of these treatments. PMID:25830041

    Glioblastoma multiforme (GBM) is well known as the most common malignant primary brain tumor. It could easily spread into the adjacent or distant brain tissue by infiltration, direct extension and cerebro-spinal fluid dissemination. The extranueural metastatic spread of GBM is relatively rare but it could have more progressive disease course. We report a 39-year-old man who had multiple bone metastases and malignant pleural effusion of the GBM without primary site recurrence. PMID:25408938

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

    Orbital metastases from breast cancer (BC) are rare, but often debilitating. BC accounts for nearly half of metastases to the orbit. Orbital metastases may be discovered years after the initial diagnosis of BC, and are rare at initial presentation. A search of the institutional data base at an academic cancer center identified BC patients who developed or presented with orbital metastases from 2000 to 2013. Baseline characteristics, treatment modalities, survival and treatment responses were collected from the electronic medical record. There were 20 patients identified with orbital metastases (0.7% of all BC cases). The median age at diagnosis of BC was 49 years; 80% had estrogen positive disease. The interval between the initial diagnosis of BC and the presentation of orbital metastases was 8.5 years (0-19 years). Orbital disease was the initial presentation of BC in two cases. Three patients developed bilateral orbital metastases and seven had accompanying brain metastases. The most common presentation was decreased vision (55%), followed by diplopia (25%). The median survival after orbital metastases was 24 months. Thirteen patients (65%) received local radiation therapy. Of those radiated, 90% reported improvement of orbital symptoms. Other treatments included intraocular bevacizumab, surgery, and systemic therapy. Orbital metastases tend to occur in estrogen receptor positive disease and are often found years after BC onset. Orbital metastases may be associated with the development of brain metastases. Radiotherapy is the preferred local therapy and had high symptom control in this cohort. Oncologists should be aware of the signs of orbital metastases and the treatment options. PMID:27143519

    Clinical management of breast cancer is increasingly personalized and based on molecular profiling. Often, primary tumors are used as proxies for systemic disease at the time of recurrence. However, recent studies have revealed substantial discordances between primary tumors and metastases, both with respect to traditional clinical treatment targets and on the genomic and transcriptomic level. With the increasing use of molecularly targeted therapy, discordance of actionable molecular targets between primary tumors and recurrences can result in nonoptimal treatment or unnecessary side effects. The purpose of this review is to illuminate the extent of cancer genome evolution through disease progression and the degree of molecular concordance between primary breast cancers and matched metastases. We present an overview of the most prominent studies investigating the expression of endocrine receptors, transcriptomics, and genome aberrations in primary tumors and metastases. In conclusion, biopsy of metastatic lesions at recurrence of breast cancer is encouraged to provide optimal treatment of the disease. Furthermore, molecular profiling of metastatic tissue provides invaluable mechanistic insight into the biology underlying metastatic progression and has the potential to identify novel, potentially druggable, drivers of progression.

    Purpose: To evaluate a retrospective single-institution outcome after hypofractionated stereotactic body radiotherapy (SBRT) for adrenal metastases. Methods and Materials: Between February 2002 and December 2009, we treated 48 patients with SBRT for adrenal metastases. The median age of the patient population was 62.7 years (range, 43-77 years). In the majority of patients, the prescription dose was 36 Gy in 3 fractions (70% isodose, 17.14 Gy per fraction at the isocenter). Eight patients were treated with single-fraction stereotactic radiosurgery and forty patients with multi-fraction stereotactic radiotherapy. Results: Overall, the series of patients was followed up for a median of 16.2 months (range, 3-63 months). At the time of analysis, 20 patients were alive and 28 patients were dead. The 1- and 2-year actuarial overall survival rates were 39.7% and 14.5%, respectively. We recorded 48 distant failures and 2 local failures, with a median interval to local failure of 4.9 months. The actuarial 1-year disease control rate was 9%; the actuarial 1- and 2-year local control rate was 90%. Conclusion: Our retrospective study indicated that SBRT for the treatment of adrenal metastases represents a safe and effective option with a control rate of 90% at 2 years.

    Assessing the therapeutic benefit of surgical navigation systems is a challenging problem in image-guided surgery. The exact clinical indications for patients that may benefit from these systems is not always clear, particularly for abdominal surgery where image-guidance systems have failed to take hold in the same way as orthopedic and neurosurgical applications. We report interim analysis of a prospective clinical trial for localizing small colorectal liver metastases using the Explorer system (Path Finder Technologies, Nashville, TN). Colorectal liver metastases are small lesions that can be difficult to identify with conventional intraoperative ultrasound due to echogeneity changes in the liver as a result of chemotherapy and other preoperative treatments. Interim analysis with eighteen patients shows that 9 of 15 (60%) of these occult lesions could be detected with image guidance. Image guidance changed intraoperative management in 3 (17%) cases. These results suggest that image guidance is a promising tool for localization of small occult liver metastases and that the indications for image-guided surgery are expanding.

    Purpose: We evaluated the role of Gamma Knife stereotactic radiosurgery in the multidisciplinary management of brain metastases from an undiagnosed primary cancer. Methods and Materials: Twenty-nine patients who had solitary or multiple brain metastases without a detectable primary site underwent stereotactic radiosurgery between January 1990 and March 2007 at the University of Pittsburgh. The median patient age was 61.7 years (range, 37.9-78.7 years). The median target volume was 1.0 cc (range, 0.02-23.6 cc), and the median margin radiosurgical dose was 16 Gy (range, 20-70 Gy). Results: After radiosurgery, the local tumor control rate was 88.5%. Twenty four patients died and 5 patients were living at the time of this analysis. The overall median survival was 12 months. Actuarial survival rates from stereotactic radiosurgery at 1 and 2 years were 57.2% and 36.8%, respectively. Factors associated with poor progression-free survival included large tumor volume (3 cc or more) and brainstem tumor location. Conclusions: Radiosurgery is an effective and safe minimally invasive option for patients with brain metastases from an unknown primary site.

    Background and Objectives: Robotic-assisted laparoscopic surgery is increasingly used for the management of patients with gynecologic malignancies. The rate of port-site metastases in patients undergoing these procedures is unknown. Methods: We conducted a retrospective cohort analysis of a prospective database. A total of 220 women underwent robotic-assisted surgery from 2007 through 2011. Malignancy was detected in 145 cases, and 142 met the inclusion criteria with histologically proven cancer and robotically completed surgery. All women who underwent surgical treatment for their malignancies were followed up at the study site for oncology treatments. Results: There were 710 potential port sites for metastasis. We found that 2 of 142 patients each had a single port-site metastasis, for an overall rate of 1.41%, or 0.28% per trocar site. Recurrent disease was not isolated in the two patients found to have port-site metastases because both had concurrent sites of pelvic recurrence. Conclusion: The rate of port-site metastases in patients undergoing robotic-assisted laparoscopic surgery for gynecologic malignancies is similar to the published rate in the literature for traditional laparoscopic oncology.

    Benign metastasizing leiomyoma (BML) is a rare condition that occurs in all age groups and that is particularly prevalent among women of late childbearing age. All patients have a history of uterine leiomyoma and/or myomectomy, often associated with distant metastases from the uterus, which commonly occurs in the lung. We report the case of a 32-year-old young woman suffering from chest stuffiness, labored respiration and weakness after a myomectomy performed one month earlier. The chest CT showed a diffuse miliary shadow in both sides of her lungs, but serum tumor markers such as CA125, CA199, carcinoembryonic antigen (CEA), neuron specific enolase (NSE), and CYFRA21-1 were normal. The patient underwent a lung biopsy by thoracoscopic surgery after four weeks of anti-TB treatment; there were no significant changes in the chest CT. H&E staining showed that the tumor cells had characteristics of smooth muscle cell differentiation. Immunohistochemical staining showed a low tumor cell proliferation index, which indicated that the likelihood of a malignancy was not high. There was no expression of CD10, indicating a diagnosis of pulmonary benign metastasizing leiomyoma (PBML). Smooth muscle actin (SMA) and desmin as specific markers of smooth muscle and the estrogen receptor (ER) and progesterone receptor (PR) were all strongly positive, which is characteristic of PBML. The patient was given the anti-estrogen tamoxifen for 3 months. With no radiological evidence of disease development and further distant metastasis, the patient will continue to be followed.

    The total absorbed dose after systemic administration of 89Sr has been determined by measuring directly its activity in bone metastases. Autoradiography was performed on sections of bones obtained from patients treated with 89Sr to study the pattern of deposition. Discs of 5 and 8 mm diameter were cut from metastatic sites and normal bone. The beta-ray activity was determined with a scintillation counter, which was calibrated using similar bovine cancellous bone discs, onto which a known activity of 89Sr was transferred by pipette. From the activity measured, the initial activity (at the time of 89Sr administration) was calculated. The absorbed dose was estimated using the methodology described in NCRP Report No. 58. The estimated initial activity of 89Sr in the bone metastases varied from 2.3 to 240 MBq kg-1, with a mean value of 31 +/- 27 MBq kg-1. The total absorbed dose ranged from 1.3 to 64 Gy, with a mean of 18 +/- 16 Gy. The average total dose to normal bone sites was 1.1 +/- 0.4 Gy. The metastases to normal bone dose ratio in individual samples varied from 8 +/- 4 to 40 +/- 25. These estimates are in agreement with those obtained previously by indirect methods. PMID:7675358

    Brain metastases are the most common intracranial tumors in adults, accounting for over half of all lesions. Whole-brain radiation therapy (WBRT) has been a cornerstone in the management of brain metastases for decades. Recently, stereotactic radiosurgery (SRS) has been considered as a definitive or postoperative approach instead of WBRT, to minimize the risk of cognitive impairment that may be associated with WBRT. This is the case report of a 74-year-old female patient who was diagnosed with lung cancer in November, 2002, and histopathologically confirmed brain metastases in January, 2005. The patient received 5 treatments with Gamma Knife SRS for recurring brain metastases between 2005 and 2014. The patient remains highly functional, with stable intracranial disease at 10 years since first developing brain metastases, and with stable lung disease. Therefore, Gamma Knife SRS is a safe and effective treatment modality for patients with recurrent intracranial metastases, with durable local control and minimal cognitive impairment. PMID:27073647

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

    Distant metastases from thyroid cancer of follicular origin are uncommon. Treatment includes levothyroxine administration at suppressive doses, focal treatment modalities with surgery, external radiation therapy and thermal ablation, and radioiodine in patients with uptake of (131)I in their metastases. Two thirds of distant metastases will become refractory to radioiodine at some point, and when there is a significant tumor burden and documented progression on imaging, a treatment with a kinase inhibitor may provide benefits.

    Brain metastases are associated with a dismal prognosis. Whether brain metastases harbor distinct genetic alterations beyond those observed in primary tumors is unknown. We performed whole-exome sequencing of 86 matched brain metastases, primary tumors and normal tissue. In all clonally related cancer samples, we observed branched evolution, where all metastatic and primary sites shared a common ancestor yet continued to evolve independently. In 53% of cases, we found potentially clinically informative alterations in the brain metastases not detected in the matched primary-tumor sample. In contrast, spatially and temporally separated brain metastasis sites were genetically homogenous. Distal extracranial and regional lymph node metastases were highly divergent from brain metastases. We detected alterations associated with sensitivity to PI3K/AKT/mTOR, CDK, and HER2/EGFR inhibitors in the brain metastases. Genomic analysis of brain metastases provides an opportunity to identify potentially clinically informative alterations not detected in clinically sampled primary tumors, regional lymph nodes, or extracranial metastases.

    F-NaF is a radiopharmaceutical widely used in PET imaging to detect bone metastases. Several cases of F-NaF uptake from brain metastases have been described, but a specific protocol for the evaluation of brain metastases with F-NaF has not been developed yet. Here we report images of F-NaF PET/CT, standard CT, and MRI of a brain metastasis in a patient with non-small lung cancer. Through a dynamic acquisition procedure, we have identified the first minutes after injection as the preferable time point of imaging acquisition for the study of brain metastases with F-NaF.

    Prostate cancer is the most common non-cutaneous malignancy for men. The skeleton is the most common metastatic site but, following an improvement in survival, metastases in uncommon sites are being found more frequently in clinical practice, especially brain metastases. Despite the new drugs now available for metastatic castration resistant prostate cancer, no clinical evidence exists about their effectiveness on brain metastases. We describe the clinical history of 3 patients treated with cabazitaxel plus whole brain radiotherapy. These case reports demonstrate that cabazitaxel is highly active and well tolerated in brain metastases. PMID:24945013

    A substantial portion of patients with newly diagnosed gastric cancer has distant metastases (M1 disease). These patients have a very poor prognosis and it is generally accepted that they should be treated with noncurative intent. Because it dramatically changes prognosis and treatment plans, it is very important to diagnose distant metastases. In this article, the definition, pathways, incidence and sites of distant metastases in gastric cancer are described. Subsequently, the current performance of imaging in detecting distant metastases in newly diagnosed gastric cancer is outlined and future prospects are discussed. PMID:26457011

    Stereotactic radiosurgery (SRS) has been increasingly employed as an alternative to whole brain radiation therapy in patients with brain metastases, with the aim to reduce its potential toxicity. We have evaluated clinical outcomes of SRS as initial treatment for brain metastases in patients 70 years and older. Between November 2007 and October 2011, 102 patients of 70 years and older with 1-4 metastases were treated with SRS. The primary end point of the study was overall survival. Secondary end points were local control and distant failure rates, cause of death, performance measurements, and toxicity of treatment. At a median follow-up of 11.0 months (range 1-48 months), median survival and median time to distant failure were 13.2 and 10 months, respectively. The 1- and 2-year survival rates were 63 and 28 %, and respective distant failure rates were 54 and 78 %. Forty-five patients succumbed to their extracranial disease and 14 patients died of progressive intracranial disease. Nine patients recurred locally after SRS. The 1- and 2-year local control rates were 90 and 84 %, respectively. Evaluation of neurocognitive function using the Mini-Mental State Examination (MMSE) showed no significant neurocognitive decline after SRS. MMSE score improved in 15 % of patients, worsened in 12 % of patients, and remained stable in the others. Severe neurological complications were reported in 7 (7 %) patients, requiring surgery or medical treatment. Initial treatment with SRS with close monitoring may represent a relatively safe treatment strategy associated with survival benefit, with outcomes similar to those reported in historical series of SRS for younger patients.

    Two patients with multiple lung metastases (≥ 5) were treated using frameless stereotactic body radiation therapy (SBRT) on an Elekta Axesse linear accelerator equipped with an interdigitation-capable multileaf collimator and four-dimensional cone-beam CT (4D CBCT). The technique and the early clinical outcomes were evaluated. Patient A with five lung metastases and Patient B with seven lung metastases underwent SBRT (48 Gy/8 fractions for Patient A, 42 Gy/7 fractions for Patient B). The treatments were administered using a 6 MV photon beam. The nominal dose rate was 660 MUs/min. Patients were positioned and immobilized using thermoplastic masks and image guidance was done using 4D CBCT. The targets were delineated on the images of the 4D CT, and the positron emission tomography-computed tomography (PET-CT) images were taken as references. A two-step, volumetric-modulated arc therapy (VMAT) plan was designed for each patient. Step 1: the lesions in one lung were irradiated by a 210° arc field; Step 2: the rest of the lesions in the other lung were irradiated by a 120° arc field. Plans were evaluated using conformity index (CI) and homogeneity index (HI). Patients were followed up and adverse events were graded according to the Common Terminology Criteria for Adverse Events v4.0 (CTCAE v4.0). The beam-on time of each treatment was less than 10 min. The CI and HI for the two plans were 0.562, 0.0709 and 0.513, 0.0794, respectively. Pulmonary function deteriorated slightly in both patients, and the patient with seven lung lesions was confirmed to have Grade 1 radiation pneumonitis. The technique was fast, accurate, and well tolerated by patients, and the two-step plan is a helpful design in reducing the dose to the lungs. PMID:25207400

    BACKGROUND: The incidence of central nervous system metastasis from primary breast cancer has steadily increased with introduction of more effective molecular-targeted therapies resulting in improved long-term survival. Current standard-of-care treatment modalities for CNS metastases include microsurgical resection, whole-brain radiation therapy, and stereotactic radiosurgery, either alone or in combination. There are currently no FDA-approved drugs with an indication for breast cancer brain metastases. Clearly, there is a dire need to identify biomarkers permitting earlier and accurate diagnosis of CNS metastases, development of prevention strategies in high-risk individuals, and establishing more effective treatment options such as targeted systemic and intrathecal therapies. METHODS: Extracted DNA from metastatic brain tumors (MBTs) and matched tissues from primary breast tumors was quantified and array comparative genomic hybridizations (aCGH) were performed with Agilent SurePrint arrays (G3 ISCA CGH + SNP 180K) using a commercially-available, genetically-normal female DNA standard. Bioinformatics analysis was performed using Agilent CytoGenomics Edition 2.5.8.1. Data were filtered against the Cancer Gene Census (Wellcome Trust Sanger Institute) to identify genes with well-characterized roles in cancer. RESULTS: From genomic copy number data analysis tailored to uncover the most frequent gene aberrations in breast cancer MBTs, we identified that MYC oncogene amplification was among the most common. Pathway analysis of the analyzed gene set of recurring gene aberrations identified the Human Embryonic Stem Cell Pluripotency pathway as being over-represented. The genes in this pathway showing copy number gain include NTRK1, PIK3CA and SOX2. Direct comparisons of MBTs with their matched primary tumor (n = 4) revealed a range of examples for highly similar and divergent patterns of gene aberrations. In one case ERBB2 was confirmed to be in the MBT, and not in the

    Purpose: Estimating the cost-effectiveness of whole-brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS), including Gamma Knife radiosurgery (GKRS), requires the quantitative measurement of patients’ health states after treatment. We sought to quantify individuals’ preferences for the relevant health states after WBRT or GKRS for brain metastases on a 0 to 1 scale, where 1 is perfect health and 0 is death. Methods: We prospectively measured utilities in patients with brain metastases evaluated at Yale for consideration of WBRT and/or GKRS, as well as oncology nurses who had cared for patients with brain metastases before and after WBRT or GKRS, using the Standard Gamble (SG) technique. Demographic information was also collected. Nonparametric tests were used to compare potential differences in utility values and for subgroups based on demographic characteristics. Results: There were 24 patients and 31 nurses who completed the study between December 2013 and May 2015. Median utilities ranged from 0.85 for the status-post (S/P) GKRS state to 0.25 (for neurologic dying). The median utility of being S/P WBRT was 0.70 compared to 0.85 S/P GKRS (p < 0.001). The cognitive decline from WBRT was associated with a notably low utility score of 0.30. There were no statistically significant differences between patients’ and nurses’ median utility scores. Conclusions: These SG utilities provide unique insights into brain metastases-related health states from the patient and provider perspective. As perceived by individuals with direct knowledge of the health states in question, WBRT has a significantly lower utility compared to GKRS. Cognitive decline following WBRT is associated with significant perceived reduction in quality of life. Differences in the relative importance of overall survival and quality of life with treatment existed between patients with different stages of disease. These utilities can be used to calculate quality-adjusted life

    The role of perioperative chemotherapy in the management of initially resectable colorectal liver metastases (CRLM) is still unclear. The EPOC trial [the European Organization for Research and Treatment of Cancer (EORTC) 40983] is an important study that declares perioperative chemotherapy as the standard of care for patients with resectable CRLM, and the strategy is widely accepted in western countries. Compared with surgery alone, perioperative FOLFOX therapy significantly increased progression-free survival (PFS) in eligible patients or those with resected CRLM. Overall survival (OS) data from the EPOC trial were recently published in The Lancet Oncology, 2013. Here, we discussed the findings and recommendations from the EORTC 40983 trial. PMID:25713806

    Brain metastases management has evolved over the last fifteen years and may use varying strategies, including more or less aggressive treatments, sometimes combined, leading to an improvement in patient's survival and quality of life. The therapeutic decision is subject to a multidisciplinary analysis, taking into account established prognostic factors including patient's general condition, extracerebral disease status and clinical and radiological presentation of lesions. In this article, we propose a management strategy based on the state of current knowledge and available therapeutic resources. PMID:25649388

    OBJECTIVE The aim of this study was to systematically review the literature on reported outcomes following decompression surgery for spinal metastases. METHODS The authors conducted MEDLINE, Scopus, and Web of Science database searches for studies reporting clinical outcomes and complications associated with decompression surgery for metastatic spinal tumors. Both retrospective and prospective studies were included. After meeting inclusion criteria, articles were categorized based on the following reported outcomes: survival, ambulation, surgical technique, neurological function, primary tumor histology, and miscellaneous outcomes. RESULTS Of the 4148 articles retrieved from databases, 36 met inclusion criteria. Of those included, 8 were prospective studies and 28 were retrospective studies. The year of publication ranged from 1992 to 2015. Study size ranged from 21 to 711 patients. Three studies found that good preoperative Karnofsky Performance Status (KPS ≥ 80%) was a significant predictor of survival. No study reported a significant effect of time-to-surgery following the onset of spinal cord compression symptoms on survival. Three studies reported improvement in neurological function following surgery. The most commonly cited complication was wound infection or dehiscence (22 studies). Eight studies reported that preoperative ambulatory or preoperative motor status was a significant predictor of postoperative ambulatory status. A wide variety of surgical techniques were reported: posterior decompression and stabilization, posterior decompression without stabilization, and posterior decompression with total or subtotal tumor resection. Although a wide range of functional scales were used to assess neurological outcomes, four studies used the American Spinal Injury Association (ASIA) Impairment Scale to assess neurological function. Four studies reported the effects of radiation therapy and local disease control for spinal metastases. Two studies reported that

    Most patients with colorectal liver metastases are treated within a multimodal therapy regime whereby liver resection is a key point in the curative treatment concept. The achievement of an R0 situation is of vital importance for long-term survival. Besides general operability and the assessment of comorbidities, resection depends on the quality of liver parenchyma (functional resectability) and the anatomical position of the tumor (oncological resectability). The improvement of operation techniques and perioperative medicine nowadays allow complex surgical procedures for metastasis surgery. This article presents the methods for the assessment of resectability and modern strategies of preoperative conditioning as well as approaches for extended liver resection. PMID:24317339

    Studies of twenty-five patients with loculated leptomeningeal tumor metastases diagnosed by CT and/or MR were analyzed retrospectively. Medulloblastoma was the most frequent primary tumor (8/25, 32%). Four subgroups of loculated patterns were identified. Type A included mass(es) limited to the subarachnoid space without obvious direct parenchymal infiltration; this pattern occurred in 12 patients, of whom five had associated diffuse pattern. Type B was characterized by mass(es) still predominantly in the subarachnoid space but with minor transpinal parenchymal infiltration; this pattern was found in five patients. Type C comprised subarachnoid mass(es) with marked transpinal extension mimicking parenchymal lesion; this pattern was observed in three patients. Type D consisted of subarachnoid mass(es) growing along the perineural CSF space; this pattern was noted in two patients. Additionally, two patients presented with combined A and C patterns, and one patient had a combined B and C pattern. More than half the patients (14/25, 56%) presented with a single lesion. The most frequent locations were the suprasellar cistern, ventricular walls, and lateral recesses of the fourth ventricle, Gd-DTPA-enhanced T1-weighted MR images appeared best for demonstrating the site and extent of disease. Recognition of the loculated patterns of leptomeningeal metastases, which are less common than the diffuse pattern, is important to radiologists and clinicians for correct diagnosis and proper management of patients with this disease.

    Colorectal carcinoma (CRC) is the third most common cancer, and approximately 35%-55% of patients with CRC will develop hepatic metastases during the course of their disease. Surgical resection represents the only chance of long-term survival. The goal of surgery should be to resect all metastases with negative histological margins while preserving sufficient functional hepatic parenchyma. Although resection remains the only chance of long-term survival, management strategies should be tailored for each case. For patients with extensive metastatic disease who would otherwise be unresectable, the combination of advances in medical therapy, such as systemic chemotherapy (CTX), and the improvement in surgical techniques for metastatic disease, have enhanced prognosis with prolongation of the median survival rate and cure. The use of portal vein embolization and preoperative CTX may also increase the number of patients suitable for surgical treatment. Despite current treatment options, many patients still experience a recurrence after hepatic resection. More active systemic CTX agents are being used increasingly as adjuvant therapy either before or after surgery. Local tumor ablative therapies, such as microwave coagulation therapy and radiofrequency ablation therapy, should be considered as an adjunct to hepatic resection, in which resection cannot deal with all of the tumor lesions. Formulation of an individualized plan, which combines surgery with systemic CTX, is a necessary task of the multidisciplinary team. The aim of this paper is to discuss different approaches for patients that are treated due to CRC liver metastasis. PMID:24876733

    We report measurements of absorbed dose to vertebral metastases in ten patients referred for 89Sr therapy for disseminated prostatic carcinoma. Patients received a tracer dose of 85Sr at the time of 89Sr treatment and metastatic strontium retention was monitored scintigraphically for 6 mo. Metastatic 85Sr activity corrected for tissue attenuation was measured using the conjugate view principle, with special care taken to eliminate errors due to the selection of the metastatic region of interest. Metastatic volume was determined from high resolution CT images, and density inferred from Hounsfield number using the QCT bone mineral calibration of Genant and Cann. The mean absorbed dose was 850 rad/mCi (23 cGy/MBq) with a range from 220-2260 rad/mCi (6 to 61 cGy/MBq). The wide range found was consistent with the variation expected to arise due to differences in strontium renal plasma clearance (range 0.1-11.81/day) and extent of skeletal metastatic disease (varying from two small metastases to a superscan on [99mTc]MDP images) among the patients studied.

    Brain metastases are the most common malignant intracranial tumors and carry a poor prognosis. The management of brain metastases may include a variety of treatment modalities including surgical resection, radiation therapy, and/or systemic therapy. The traditional treatment for brain metastasis involved whole brain irradiation. However, improved systemic control of primary cancers has led to longer survival for some groups of patients and there is increasing need to consider the late effects of radiation to the entire brain. With advances in imaging and radiation treatment planning and delivery stereotactic radiosurgery has become more frequently utilized and may be delivered through Gamma Knife Stereotactic Radiosurgery or linear accelerator-based systems. Furthermore, experience in treating thousands of patients on clinical trials has led to diagnosis-specific prognostic assessment systems that help guide our approach to the management of this common clinical scenario. This review provides an overview of the literature supporting radiotherapy for brain metastasis and an update on current radiotherapeutic options that is tailored for the nonradiation oncologist.

    Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016. PMID:26713674

    One in four breast cancer patients is at risk of developing bone metastases in her life time. The early prevention of bone metastases is a crucial challenge. It has been suggested that the use of zoledronic acid (ZOL) in the adjuvant setting may reduce the persistence of disseminated tumor cells and thereby might improve outcome, specifically in a population of patients with a low estrogen microenvironment. More recently, the results of a large meta-analysis from 41 randomized trials comparing a bisphosphonate (BP) to placebo or to an open control have been presented at the 2013 San Antonio Breast Cancer Meeting. Data on 17,016 patients confirm that adjuvant BPs, irrespective of the type of treatment or the treatment schedule and formulation (oral or intra-venously (IV)), significantly reduced bone recurrences and improved breast cancer survival in postmenopausal women. No advantage was seen in premenopausal women. BPs are soon likely to become integrated into standard practice. Published data on the mechanisms involved in tumor cell seeding from the primary site, in homing to bone tissues and in the reactivation of dormant tumor cells will be reviewed; these might offer new ideas for innovative combination strategies.

    Management of patients with hepatic metastases as the sole metastatic site at diagnosis of gastric cancer (synchronous setting) or detected during follow-up (metachronous) is controversial. The prevailing attitude in these cases is passive, leading to surgical palliation and, possibly, to chemotherapy. Authors focused this editorial in order to promote a more pragmatic attitude. They stress the importance of recognizing the good candidates to curative surgery of both gastric cancer and hepatic metastases (synchronous setting) or hepatic disease alone (metachronous disease) from those who will not benefit from surgical therapy. In fact, in adequately selected subgroup of patients surgery, especially if integrated in multimodal therapeutic strategies, may achieve unexpected 5-year survival rates, ranging from 10% to 40%. The critical revision of the literature suggests that some simple clinical criteria exist that may be effectively employed in patients selection. These are mainly related to the gastric cancer (factors T, N, G) and to the extent of hepatic involvement (factor H). Upon these criteria it is possible to adequately select about 50% of cases. In the remaining 50% of cases a critical discussion on a case-by-case basis is recommended, considering that among these patients some potential long-survivors exist, that survival is strictly influenced by the ablation of the tumor bulk and by multimodality treatments including chemotherapy and that in expert institutions this kind of surgery is performed with very low mortality and morbidity rates.

    Metastasis is the complex process by which primary tumor cells migrate and establish secondary tumors in an adjacent or distant location in the body. Early detection of metastatic disease and effective therapeutic options for targeting these detected metastases remain impediments to effectively treating patients with advanced cancers. If metastatic lesions are identified early, patients might maximally benefit from effective early therapeutic interventions. Further, monitoring patients whose primary tumors are effectively treated for potential metastatic disease onset is also highly valuable. Finally, patients with metastatic disease can be monitored for efficacy of specific therapeutic interventions through effective metastatic detection techniques. Thus, being able to detect and visualize metastatic lesions is key and provides potential to greatly improve overall patient outcomes. In order to achieve these objectives, researchers have endeavored to mechanistically define the steps involved in the metastatic process as well as ways to effectively detect metastatic progression. We presently overview various preclinical and clinical in vitro and in vivo assays developed to more efficiently detect tumor metastases, which provides the foundation for developing more effective therapies for this invariably fatal component of the cancerous process.

    Brain metastases (BMs) are diagnosed in 10%-40% of all patients with cancer, and the incidence continues to increase along with the number of long-term survivors. When BMs occur, they are often associated with a myriad of symptoms, including neurologic dysfunction and functional decline; both are difficult to manage and can be distressing for patients and their caregivers. Although clinically significant findings have not kept up with the rapid pace of scientific breakthroughs in understanding the mechanisms of BMs, novel approaches that affect the prognosis of patients with BMs have been introduced in clinical practice. At a Glance • Screening for brain metastases (BMs) is not routinely performed in patients with no neurologic symptoms. However, screening is indicated in lung cancer and possibly in the context of high-risk cancers. • Individual differences in patients warrant a personalized approach in the management of BMs. • Whole brain radiation therapy and steroids are considered to be the cornerstones of treatment for BMs. PMID:26207714

    We report an aggressively behaving malignant trichogenic tumor arising in a trichoblastoma (TB) with widespread lymphatic and hematogenous metastases in a 55-year-old man with a concomitant B-cell chronic lymphocytic leukemia. The primary tumor had been present and unchanged for as long as 40 years before excision. Typical trichogenic TB with dystrophic calcification and even ossification was still present peripheral to the malignant transformation. The malignant neoplasm consisted of basaloid cells, spindle cells arranged in fascicles and densely packed rounded nests or "cell balls." The metastases consisted of immature basaloid cells and cell balls, and the recurrences became successively more undifferentiated. The residual TB reacted with antibodies to cytokeratin (CK) 6, 8, 14, and 17 and focally to S-100; the malignant primary tumor reacted uniformly with antibodies to vimentin and only focally with antibodies to CK and S-100. The metastatic tumor had lost epidermal CK expression but maintained expression of S-100 in paraffin-embedded tissues. Trichoblastic differentiation was confirmed in frozen tissues with antibodies to hair keratins. No expression of p53 or bcl-2 was identified, but p-glycoprotein (MDR-1 gene related) was expressed by primary and metastatic tumor cells. We believe that this neoplasm is best classified as a trichoblastic carcinoma arising in a TB in association with a B-cell chronic lymphocytic leukemia. This case illustrates that TBs have the potential for malignant transformation and aggressive behavior. PMID:10874673

    For a long time, treatment of peritoneal metastases (PM) was mostly palliative and thus, this status was link with "terminal status/despair". The current multimodal treatment strategy, consisting of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), has been strenuously achieved over time, but seems to be the best treatment option for PM patients. As we reviewed the literature data, we could emphasize some milestones and also, controversies in the history of proposed multimodal treatment and thus, outline the philosophy of this approach, which seems to be an unusual one indeed. Initially marked by nihilism and fear, but benefiting from a remarkable joint effort of human and material resources (multi-center and -institutional research), over a period of 30 years, CRS and HIPEC found their place in the treatment of PM. The next 4 years were dedicated to the refinement of the multimodal treatment, by launching research pathways. In selected patients, with requires training, it demonstrated a significant survival results (similar to the Hepatic Metastases treatment), with acceptable risks and costs. The main debates regarding CRS and HIPEC treatment were based on the oncologists' perspective and the small number of randomized clinical trials. It is important to statement the PM patient has the right to be informed of the existence of CRS and HIPEC, as a real treatment resource, the decision being made by multidisciplinary teams.

    Colorectal cancer is one of the few malignant tumors in which synchronous or metachronous liver metastases [colorectal liver metastases (CRLMs)] may be treated with surgery. It has been demonstrated that resection of CRLMs improves the long-term prognosis. On the other hand, patients with un-resectable CRLMs may benefit from chemotherapy alone or in addition to liver-directed therapies. The choice of the most appropriate therapeutic management of CRLMs depends mostly on the diagnostic imaging. Nowadays, multiple non-invasive imaging modalities are available and those have a pivotal role in the workup of patients with CRLMs. Although extensive research has been performed with regards to the diagnostic performance of ultrasonography, computed tomography, positron emission tomography and magnetic resonance for the detection of CRLMs, the optimal imaging strategies for staging and follow up are still to be established. This largely due to the progressive technological and pharmacological advances which are constantly improving the accuracy of each imaging modality. This review describes the non-invasive imaging approaches of CRLMs reporting the technical features, the clinical indications, the advantages and the potential limitations of each modality, as well as including some information on the development of new imaging modalities, the role of new contrast media and the feasibility of using parametric image analysis as diagnostic marker of presence of CRLMs. PMID:26217455

    Brain metastases (BM) are the most common intracranial tumors and their incidence is increasing. Untreated brain metastases are associated with a poor prognosis and a poor performance status. Metastasis development involves the migration of a cancer cell from the bulk tumor into the surrounding tissue, extravasation from the blood into tissue elsewhere in the body, and formation of a secondary tumor. In the recent past, important results have been obtained in the management of patients affected by BM, using surgery, radiation therapy, or both. Conventional chemotherapies have generally produced disappointing results, possibly due to their limited ability to penetrate the blood-brain barrier. The advent of new technologies has led to the discovery of novel molecules and pathways that have better depicted the metastatic process. Targeted therapies such as bevacizumab, erlotinib, gefitinib, sunitinib and sorafenib, are all licensed and have demonstrated improved survival in patients with metastatic disease. In this review, we will report current data on targeted therapies. A brief review about brain metastatic process will be also presented. PMID:23340652

    The purpose of this study was to evaluate technical success, technique effectiveness, and survival following radiofrequency ablation for breast cancer liver metastases and to determine prognostic factors. Forty-three patients with 111 breast cancer liver metastases underwent CT-guided percutaneous radiofrequency (RF) ablation. Technical success and technique effectiveness was evaluated by performing serial CT scans. We assessed the prognostic value of hormone receptor status, overexpression of human epidermal growth factor receptor 2 (HER2), and presence of extrahepatic tumor spread. Survival rates were calculated using the Kaplan-Meier method. Technical success was achieved in 107 metastases (96%). Primary technique effectiveness was 96%. During follow-up local tumor progression was observed in 15 metastases, representing a secondary technique effectiveness of 86.5%. The overall time to progression to the liver was 10.5 months. The estimated overall median survival was 58.6 months. There was no significant difference in terms of survival probability with respect to hormone receptor status, HER2 overexpression, and presence of isolated bone metastases. Survival was significantly lower among patients with extrahepatic disease, with the exception of skeletal metastases. We conclude that CT-guided RF ablation of liver metastases from breast cancer can be performed with a high degree of technical success and technique effectiveness, providing promising survival rates in patients with no visceral extrahepatic disease. Solitary bone metastases did not negatively affect survival probability after RF ablation.

    Extracranial metastases from glioblastoma are rare. We report two patients with extracranial metastases from glioblastoma. Case 1 concerns a 59-year-old woman with multiple metastases that spread early in the course of disease. What makes this case unusual is that the tumor had grown into the falx close to the straight sinus and this might be an explanation to the early and extensive metastases. Case 2 presents a 60-year-old man with liver metastasis found at autopsy, and, in this case, it is more difficult to find an explanation. This patient had two spontaneous intracerebral bleeding incidents and extensive bleeding during acute surgery with tumor removal, which might have induced extracranial seeding. The cases presented might have hematogenous spreading in common as an explanation to extracranial metastases from GBM. PMID:27247816

    The accuracy levels of serial radioisotope bone scans and conventional bone radiographs in assessing the response of bone metastases to systemic therapy were compared in 34 women with metastatic breast cancer. Each patient had measurable or evaluable nonosseous metastases, which were assessed independently of skeletal disease. The bone scan was found to be more accurate and sensitive indicator of the status of bone metastases than the radiograph. The bone scan correlated well with response of soft tissue or visceral disease, while the results of repeated bone radiographs were frequently misleading. With use of a digital model, it was possible to accurately measure the area of skeletal involvement of the bone scan, and from this derive quantitative criteria for response in bone metastases analogous to response criteria currently in use for soft tissue and visceral disease. It is suggested that serial quantitative bone scans be done, in preference to radiographs, to assess the response of bone metastases to systemic therapy.

    1990-01-01

    This paper presents arguments for and against the motion that 'Resection of liver metastases from colorectal carcinoma does not benefit the patient'. The case for this proposition is summarised as follows: survival after resection of small metastases is not markedly different from the natural history of similar tumours; patients with metastases apparently localised to one area of the liver are uncommon, and thorough investigation further reduces the proportion of such patients; the operative mortality of liver resection has a significant adverse effect on survival after resection, and may cancel out the benefits of surgery, and finally the alternative non-operative methods of treating these patients may offer similar benefits to resection. The counter argument is simple: for a patient with liver metastases the only hope of eradication of liver disease lies in surgical resection. If this can be achieved then the prognosis is as good as for a similar primary tumour without liver metastases. PMID:2192677

    Liver metastases in colorectal cancer patients decreases the expected 5 year survival rates by a factor close to nine. It is generally accepted that resection of liver metastases should be attempted whenever feasible. This manuscript addresses the optimal therapeutic plan regarding timing of resection of synchronous liver metastases and the use of chemotherapy in combination with resection of synchronous metachronous liver metastases. The aim is to pool all published results in order to attribute a level of evidence to outcomes and identify lacking evidence areas. A systematic search of guidelines, reviews, randomised controlled, observational studies and updating a meta-analysis was performed. Data were extracted and analysed. Data failed to demonstrate an effect of timing of surgery or use of chemotherapy on overall survival. Concomitant resection of liver metastases and the primary tumour may result in lower postoperative morbidity. Systemic peri-operative chemotherapy may improve progression free survival compared to surgery alone. PMID:25666309

    TGFβ is a known driver of epithelial-mesenchymal transition (EMT) which is associated with tumor aggressiveness and metastasis. However, EMT has not been fully explored in clinical specimens of castration-resistant prostate cancer (CRPC) metastases. To assess EMT in CRPC, gene expression analysis was performed on 149 visceral and bone metastases from 62 CRPC patients and immunohistochemical analysis was performed on 185 CRPC bone and visceral metastases from 42 CRPC patients. In addition, to assess the potential of metastases to seed further metastases the mitochondrial genome was sequenced at different metastatic sites in one patient. TGFβ was increased in bone versus visceral metastases. While primarily cytoplasmic; nuclear and cytoplasmic Twist were significantly higher in bone than in visceral metastases. Slug and Zeb1 were unchanged, with the exception of nuclear Zeb1 being significantly higher in visceral metastases. Importantly, nuclear Twist, Slug, and Zeb1 were only present in a subset of epithelial cells that had an EMT-like phenotype. Underscoring the relevance of EMT-like cells, mitochondrial sequencing revealed that metastases could seed additional metastases in the same patient. In conclusion, while TGFβ expression and EMT-associated protein expression is present in a considerable number of CRPC visceral and bone metastases, nuclear Twist, Slug, and Zeb1 localization and an EMT-like phenotype (elongated nuclei and cytoplasmic compartment) was only present in a small subset of CRPC bone metastases. Mitochondrial sequencing from different metastases in a CRPC patient provided evidence for the seeding of metastases from previously established metastases, highlighting the biological relevance of EMT-like behavior in CRPC metastases.

    The prognosis-improving effect of radical surgery has been demonstrated in patients with colorectal cancer (CRC) with liver metastases. However, few studies have examined the effectiveness of treatments for CRC with metastases in organs other than the liver. The aim of the present study was to evaluate the outcome of surgical treatment for CRC with lung metastases. The study retrospectively examined 57 primary CRC patients (28 men, median age of 65 years) with synchronous lung metastases who underwent surgery between 2003 and 2012. Data such as clinicopathological parameters, metastasized organs, and the details of surgery, recurrence and survival periods were extracted and analyzed. Curative resection was performed in 10 patients (‘curative group’). Primary tumors were resected without metastasectomy in 37 patients (‘non-curative group’), whereas 10 underwent stoma surgery (‘stoma group’). All the metastasized lesions were confined to the lung and liver in the curative group. By contrast, 43% of the non-curative/stoma groups had metastases in organs other than the lung and liver. Multivariate analyses indicated the absence of extrahepatic metastases as the only predictor of curative resection in CRC patients with lung metastases. The 3-year overall survival rates for the curative, non-curative and stoma groups were estimated as 74, 20 and 17%, respectively (P=0.0007). In conclusion, curative resection was possible in CRC patients with lung metastases if other disseminated lesions were limited to the liver and this treatment resulted in a longer survival time. Furthermore, palliative resection may contribute to a better prognosis compared to stoma surgery alone in selected cases. PMID:26623047

    Object To identify pre-operative prognostic parameters for survival in patients with spinal epidural neoplastic metastasis when the primary tumour is unknown. Methods This study was a retrospective chart review of patients who underwent surgery for spinal epidural neoplastic metastases between February 1997 and January 2011. The inclusion criteria were as follows: known post-operative survival period, a Karnofsky Performance Score equal to or greater than 30 points and a post-operative neoplastic metastasis histological type. The Kaplan-Meier method was used to estimate post-operative survival, and the Log-Rank test was used for statistical inference. Results A total of 52 patients who underwent 52 surgical procedures were identified. The mean age at the time of spinal surgery was 53.92 years (std. deviation, 19.09). The median survival after surgery was 70 days (95% CI 49.97–90.02), and post-operative mortality occurred within 6 months in 38 (73.07%) patients. Lung cancer, prostate cancer, myeloma and lymphoma, the 4 most common primary tumour types, affected 32 (61.53%) patients. The three identified prognostic parameters were the following: pre-operative walking incapacity (American Spinal Injury Association, A and B), present in 86.53% of the patients (p-value = 0.107); special care dependency (Karnofsky Performance Score, 10–40 points), present in 90.38% of the patients (p-value = 0.322); and vertebral epidural neoplastic metastases that were in contact with the thecal sac (Weinstein-Boriani-Biagini, sector D), present in 94.23% of the patients (p-value = 0.643). When the three secondary prognostic parameters were combined, the mean post-operative survival was 45 days; when at least one was present, the survival was 82 days (p-value = 0.175). Conclusions Walking incapacity, special care dependency and contact between the neoplastic metastases and the thecal sac can help determine the ultimate survival of this patient population and

    Purpose: Patients with brain metastases are often treated with whole brain radiation therapy (WBRT) for purposes of palliation. The treatment of those who experience subsequent intracranial disease progression can include a second course of WBRT, although there is controversy surrounding its safety and efficacy. This study examines the outcomes in patients at Massachusetts General Hospital who underwent reirradiation. Patients and Methods: We examined the medical records of 17 patients at Massachusetts General Hospital with brain metastases who were initially treated with WBRT between 2002 and 2008 and were subsequently retreated with a second course of WBRT. The median dose for the first course of WBRT was 35 Gy (range, 28-40 Gy), with a fraction size of 2 to 3 Gy (median, 2.5 Gy). The median dose at reirradiation was 21.6 Gy (range, 14-30 Gy), with a fraction size of 1.5 to 2 Gy (median, 1.8 Gy). Results: The second course of WBRT was administered upon radiographic disease progression in all patients. Of 10 patients with complete follow-up data, 8 patients experienced complete or partial symptom resolution, and 2 did not show clinical improvement. The time to radiographic progression was 5.2 months. The median overall survival for all patients after diagnosis of metastases was 24.7 months. The median survival time after initiation of reirradiation was 5.2 months (95% CI, 1.3-8.7). In 6 patients with stable extracranial disease, the median survival time after retreatment was 19.8 months (95% CI, 2.7-{infinity}), compared with 2.5 months (95% CI, 0.8-5.5) for those with extracranial disease progression (p = 0.05). Acute adverse reactions occurred in 70.5% of patients but were mild to moderate in severity. Conclusion: In select patients and especially those with stable extracranial disease, reirradiation may be an appropriate and effective intervention to provide symptomatic relief and slow intracranial disease progression. Side effects were minimal and did not

    Metastasis is a defining feature of malignant tumors and is the most common cause of cancer-related death, yet the genetics of metastasis are poorly understood. We used massively parallel exome sequencing coupled with Sanger re-sequencing to search for metastasis-related mutations in highly metastatic uveal melanomas of the eye. Inactivating somatic mutations were identified in the gene encoding BRCA1-associated protein 1 (BAP1) on chromosome 3p21.1 in 26 of 31 (84%) metastasizing tumors, including 15 mutations causing premature protein termination, and six affecting its ubiquitin carboxy-terminal hydrolase (UCH) domains. One tumor harbored a frameshift mutation that was germline in origin, thus representing a susceptibility allele. These findings implicate loss of BAP1 in uveal melanoma metastasis and suggest the BAP1 pathway as a therapeutic target. PMID:21051595

They comprised osteolytic lesions in the femur (44), tibia (2), and humerus (5). The most frequent primary tumours were: carcinoma of the breast (37%), lung (25%), kidney (16%), rectum (9%). The remaining 13% were from the prostate gland, bladder, ovaries, uterus, chronic lymphatic leukemia, and haemangiopericytoma. Surgical treatment was supplemented by medication and physiotherapy. The choice of instrumentation (prosthesis, total prosthesis, plates, endomedullary nailing) was based on the site of the metastasis and the general condition of the patient. Palliative surgery in these cases was fully justified by the results in that it achieved the aim we set ourselves, namely to restore these unfortunate patients to as normal a lifestyle as possible.

    Brain metastases are the most common intracranial malignancy, accounting for significant morbidity and mortality in oncology patients. The current treatment paradigm for brain metastasis depends on the patient's overall health status, the primary tumor pathology, and the number and location of brain lesions. Herein, we review the modern management options for these tumors, including surgical resection, radiotherapy, and chemotherapy. Recent operative advances, such as fluorescence, confocal microscopy, and brachytherapy, are highlighted. With an increased understanding of the pathophysiology of brain metastasis come increased future therapeutic options. Therapy targeted to specific tumor molecular pathways, such as those involved in blood-brain barrier transgression, cell-cell adhesion, and angiogenesis, are also reviewed. A personalized plan for each patient, based on molecular characterizations of the tumor that are used to better target radiotherapy and chemotherapy, is undoubtedly the future of brain metastasis treatment.

    A 4-year-2-month-old female Japanese domestic cat was diagnosed with lymphangiosarcoma through tissue biopsy of an amputated leg. Two months later, the cat was euthanized, and postmortem findings revealed edema, and bruising at the caudal region of the trunk, pulmonary hemorrhage, pulmonary nodules and mediastinal lymphadenopathy. Microscopically, neoplastic tissues were observed in the dermis and subcutis of the trunk, lung, mediastinal lymph nodes, diaphragm, omentum and mesentery. The tumor cells were spindle to polygonal-shaped with nuclear pleomorphism aligning along pre-existing collagen bundles and forming irregular vascular channels in which the erythrocytes were rarely observed. These cells were immunopositive for vimentin, von Willebrand factor and CD31. Based on the histopathological and immunohistochemical features, the neoplasia was diagnosed as lymphangiosarcoma with systemic metastases. PMID:25482607

    The skeleton is a common site of metastases in lung cancer, an event associated with significant morbidities and poor outcomes. Current antiresorptive therapies provide limited benefit, and novel strategies of prevention and treatment are urgently needed. This review summarizes the latest advances and new perspectives on emerging experimental and clinical approaches to block this deleterious process. Progress propelled by preclinical models has led to a deeper understanding on the complex interplay of tumor cells in the osseous milieu, unveiling potential new targets for drug development. Improvements in early diagnosis through the use of sophisticated imaging techniques with bone serum biomarkers are also discussed in the context of identifying patients at risk and monitoring disease progression during the course of treatment.

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; α - fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was revaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

    Biochemically failing metastatic prostate cancer is typically treated with androgen ablation. However, due to the emergence of castration-resistant cells that can survive in low androgen concentrations, such therapy eventually fails. Here, we develop a partial differential equation model of the growth and response to treatment of prostate cancer that has metastasized to the bone. Existence and uniqueness results are derived for the resulting free boundary problem. In particular, existence and uniqueness of solutions for all time are proven for the radially symmetric case. Finally, numerical simulations of a tumor growing in 2-dimensions with radial symmetry are carried in order to evaluate the therapeutic potential of different treatment strategies. These simulations are able to reproduce a variety of clinically observed responses to treatment, and suggest treatment strategies that may result in tumor remission, underscoring our model's potential to make a significant contribution in the field of prostate cancer therapeutics.

    Metastatic spread, not primary tumors, is the leading cause of cancer death. Glutathione (γ-glutamyl-cysteinyl-glycine, GSH) is particularly relevant in cancer cells as it is involved in regulating carcinogenic mechanisms, growth and dissemination, and multidrug and radiation resistance. Upon interaction of metastatic cells with the vascular endothelium, a high percentage of metastatic cells with high GSH levels survive the combined nitrosative and oxidative stresses elicited by the vascular endothelium. GSH release from different organs, mainly the liver, and its interorgan transport through the blood circulation to metastatic foci, promote their growth. This review focuses on the relationship among GSH and different key mechanisms that facilitate metastatic cell survival and growth, i.e. adaptive responses to stress, cell death evasion and utilization of physiological neuroendocrine mechanisms. Different strategies that are aimed at sensitizing metastases to cancer therapy by depleting metastatic cell GSH are analyzed. PMID:26754151

    Primary splenic angiosarcoma (PSA) is the most unusual type of malignancy with early multifocal metastasis through hematogenous spread. PSA is generally believed to originate from splenic sinusoidal vascular endothelium with a high rate of metastasis and to have a poor prognosis. Its etiology and pathogenetic mechanisms have not yet been clearly described. Thus far, only approximately 200 cases have been reported. PSA has variable symptomatology with the potential to present with life-threatening complications. The diagnosis of PSA is challenging; and often late. PSA should be considered in the differential diagnosis of patients with splenomegaly and anemia of unknown etiology. Surgical treatment with splenectomy is considered the only curative intervention for potential long-term disease-free survival. Early diagnosis and treatment are very important. It is important that clinical doctors improve the understanding of PSA. Herein, we report one rare case of PSA with hepatic metastases, along with a review of the current literature. PMID:26494974

    While typically used for treating small intact brain metastases, an increasing body of literature examining tumor bed directed stereotactic radiosurgery (SRS) is emerging. There are now over 1000 published cases treated with this approach, and the first prospective trial was recently published. The ideal sequencing of tumor bed SRS is unclear. Current approaches include, a neoadjuvant treatment before resection, alone as an adjuvant after resection, and following surgery combined with whole brain radiotherapy either as an adjuvant or salvage treatment. Based on available evidence, adjuvant stereotactic radiosurgery improves local control following surgery, reduces the number of patients who require whole brain radiotherapy, and is well tolerated. While results from published series vary, heterogeneity in both patient populations and methods of reporting results make comparisons difficult. Additional prospective data, including randomized trials are needed to confirm equivalent outcomes to the current standard of care. We review the current literature, identify areas of ongoing contention, and highlight ongoing studies. PMID:25911296

    Introduction Reamed intramedullary nailing, recommended for impending fracture of a femur weakened by bone metastases, causes a rise in intramedullary pressure and increases the risk of a fat embolism syndrome. The pressure can be equalized by the technique of venting — drilling a hole into the distal cortex of the femur. Our objective was to study the current practice of orthopedic surgeons in Ontario with respect to venting during prophylactic intramedullary nailing for an impending femoral fracture due to bone metastases. Methods We mailed a questionnaire to all orthopedic surgeons from the Province of Ontario listed in the 1999 Canadian Medical Directory or on the Canadian Orthopaedic Association membership list, asking if they vent when prophylactically nailing an impending pathologic femoral fracture. The responses were modelled as a function of surgeon volume and year of graduation. Results Of the 415 surveys mailed, 223 (54%) surgeons responded. Of these, 81% reported having prophylactically treated a femoral metastatic lesion during the previous year; 67% treated 1 to 3 metastatic lesions and 14% treated more than 3; 19% did not treat a metastatic femoral lesion prophylactically. Over two-thirds of surgeons had never considered venting, whereas one-third always or sometimes vented the femoral canal. More recent graduates were 3 times more likely to vent than earlier (before 1980) graduates (odds ratio [OR] = 3.2, 95% confidence interval [CI] 1.6–6.5) as were those who treat a greater number of impending fractures (OR = 1.4, 95% CI 1.1–1.7). Conclusions Although there is a theoretical rationale for routine venting, there is disagreement among Ontario orthopedic surgeons regarding the use of this technique during prophylactic nailing for femoral metastatic lesions. Prospective evidence will be required to warrant a change in the standard of care. PMID:14680349

    Between May 1986 and August 1989, we treated 18 patients with 21 recurrent or persistent brain metastases with stereotactic radiosurgery using a modified linear accelerator. To be eligible for radiosurgery, patients had to have a performance status of greater than or equal to 70% and have no evidence of (or stable) systemic disease. All but one patient had received prior radiotherapy, and were treated with stereotactic radiosurgery at the time of recurrence. Polar lesions were treated only if the patient had undergone and failed previous complete surgical resection (10 patients). Single doses of radiation (900 to 2,500 cGy) were delivered to limited volumes (less than 27 cm3) using a modified 6MV linear accelerator. The most common histology of the metastatic lesion was carcinoma of the lung (seven patients), followed by carcinoma of the breast (four patients), and melanoma (four patients). With median follow-up of 9 months (range, 1 to 39), all tumors have been controlled in the radiosurgery field. Two patients failed in the immediate margin of the treated volume and were subsequently treated with surgery and implantation of 125I to control the disease. Radiographic response was dramatic and rapid in the patients with adenocarcinoma, while slight reduction and stabilization occurred in those patients with melanoma, renal cell carcinoma, and sarcoma. The majority of patients improved neurologically following treatment, and were able to be withdrawn from corticosteroid therapy. Complications were limited and transient in nature and no cases of symptomatic radiation necrosis occurred in any patient despite previous exposure to radiotherapy. Stereotactic radiosurgery is an effective and relatively safe treatment for recurrent solitary metastases and is an appealing technique for the initial management of deep-seated lesions as a boost to whole brain radiotherapy.

    Surgical resection of solid primary malignancies is a mainstay of therapy for cancer patients. Despite being the most effective treatment for these tumors, cancer surgery has been associated with impaired metastatic clearance due to immunosuppression. In preclinical surgery models and human cancer patients, we and others have demonstrated a profound suppression of both natural killer (NK) and T cell function in the postoperative period and this plays a major role in the enhanced development of metastases following surgery. Oncolytic viruses (OV) were originally designed to selectively infect and replicate in tumors, with the primary objective of directly lysing cancer cells. It is becoming increasingly clear, however, that OV infection results in a profound inflammatory reaction within the tumor, initiating innate and adaptive immune responses against it that is critical for its therapeutic benefit. This anti-tumor immunity appears to be mediated predominantly by NK and cytotoxic T cells. In preclinical models, we found that preoperative OV prevents postoperative NK cell dysfunction and attenuates tumor dissemination. Due to theoretical safety concerns of administering live virus prior to surgery in cancer patients, we characterized safe, attenuated versions of OV, and viral vaccines that could stimulate NK cells and reduce metastases when administered in the perioperative period. In cancer patients, we observed that in vivo infusion with oncolytic vaccinia virus and ex vivo stimulation with viral vaccines promote NK cell activation. These preclinical studies provide a novel and clinically relevant setting for OV therapy. Our challenge is to identify safe and promising OV therapies that will activate NK and T cells in the perioperative period preventing the establishment of micrometastatic disease in cancer patients.

    Purpose: To evaluate the efficacy of stereotactic radiotherapy in patients with brain metastases by comparing two different treatment regimens, single-dose radiosurgery (SRS) and fractionated stereotactic radiotherapy (FSRT). Methods and Materials: Between November 2003 and December 2008, 98 patients with brain metastases were included. Fifty-eight patients were treated with SRS, and forty were treated with FSRT. Fractionated stereotactic radiotherapy was used for large lesions or lesions located near critical structures. The median doses were 20 Gy for the SRS group and 36 Gy in 6 fractions for the FSRT group. Results: With a median follow-up period of 7 months, the median survival was 7 months for all patients, with a median of 6 months for the SRS group and 8 months for the FSRT group (p = 0.89). Local progression-free survival (LPFS) rates at 6 months and 1 year were 81% and 71%, respectively, for the SRS group and 97% and 69%, respectively, for the FSRT group (p = 0.31). Despite the fact that FSRT was used for large lesions and lesions in adverse locations, LPFS was not inferior to SRS. Toxicity was more frequently observed in the SRS group than in the FSRT group (17% vs. 5%, p = 0.05). Conclusions: Because patients treated with FSRT exhibited similar survival times and LPFS rates with a lower risk of toxicity in comparison to those treated with SRS, despite the fact that FSRT was used for large lesions and lesions in adverse locations, we find that FSRT can particularly be beneficial for patients with large lesions or lesions located near critical structures. Further investigation is warranted to determine the optimal dose/fractionation.

    Background: The most common sites of origin for neuroendocrine carcinoma are gastrointestinal tract and its accessory glands, and lungs. Materials and Methods: One-hundred fifty cases diagnosed with metastatic brain lesions were retrieved from hospital records within 5 years. For these cases, the primary neoplasm, histopathological classification, metastasis, treatment, and fate all were studied. Results: Intracranial deposits were detected in 10%. The primary lesion was in the lungs in 87% of patients, and 1 patient in the breast and 1 in esophagus. Pathological classification of the primary lesion was Grade 2 (MIB-1: 3–20%) in 1 patient and neuroendocrine carcinoma (MIB-1: ≥21%) in 14 patients. The median period from onset of the primary lesion up to diagnosis of brain metastasis was 12.8 months. About 33% of patients had a single metastasis whereas 67% patients had multiple metastases. Brain metastasis was extirpated in 33% of patients. Stereotactic radiotherapy alone was administered in 20% of patients, and brain metastasis was favorably controlled in most of the patients with coadministration of cranial irradiation as appropriate. The median survival period from diagnosis of brain metastasis was 8.1 months. Conclusion: Most of patients with brain metastasis from neuroendocrine carcinoma showed the primary lesion in the lungs, and they had multiple metastases to the liver, lymph nodes, bones, and so forth at the time of diagnosis of brain metastasis. The guidelines for accurate diagnosis and treatment of neuroendocrine carcinoma should be immediately established based on further analyses of those patients with brain metastasis. PMID:27365963

    ABSTRACT Background Ameloblastoma is a benign odontogenic tumour that may exhibit aggressive biological behaviour with local recurrence and metastasis following initial surgical resection. Surgery is the most acceptable modality of treatment, even if a biological approach is currently on study. We report a case of maxillary ameloblastoma with development of neck and brain metastases after repeated local recurrences. Molecular analysis was performed with the aim to better characterize this neoplasm and its peculiar behaviour. Methods We investigated the status of tumour protein p53 (TP53), epidermal growth factor receptor (EGFR), B-Raf proto-oncogene (BRAF) and human epidermal growth factor receptor 2 (HER2) genes with immunohistochemical, fluorescent in situ hybridization and/or direct sequencing in order to clarify their possible role in the development of this neoplasm and the possibility of a targeted treatment. Results The histological appearance of the tumour was the same in the primary lesion, in the recurrence and in the metastases. EGFR positivity was present in the recurrence and the brain metastasis, while HER2 was negative in all samples tested. Fluorescent in situ hybridization analysis for EGFR showed disomy of neoplastic cells. Direct DNA sequencing of TP53 gene exons 5 - 9 was carried out in tumour samples from the infratemporal recurrence and brain metastasis, with no mutational alteration detected. Similarly, sequencing analysis of BRAF exon 15 (V600) and EGFR gene showed wild type results in all samples tested. Conclusions Further studies are needed to identify molecular pathways that may provide an opportunity of alternative treatments and/or new potential predictive markers of local and distant spread of this rare tumour.

    Assessment of tumour response to chemotherapy is important when assessing efficacy of treatment and comparing differing therapeutic regimens. Percentage hepatic replacement (PHR) is commonly used to assess response to treatment of colorectal hepatic metastases. PHR is dependent not only on tumour volume, but also on hepatic parenchymal volume. The effect of tumour growth on hepatic parenchymal volume is unclear but is of importance owing to its effect on PHR. We assessed tumour and hepatic parenchymal weights in an animal tumour model using dissection, and tumour and hepatic parenchymal volumes in patients with colorectal hepatic metastases using CT scanning, in order to establish how hepatic parenchyma varied with change in metastasis size. There was no significant correlation between tumour and liver parenchyma in either the animal model (r = -0.03, P > 0.05) or the patient study (r = 0.3, P < 0.05). This suggests that hepatic parenchymal volume was preserved in the presence of increasing tumour volume. In a further study of computerised tomographic (CT) scans before and after treatment in patients whose tumours either responded to chemotherapy or continued to grow, change in PHR (median proportion of PHR change = 0.40) significantly (P = 0.04) underestimated the change in tumour volume (median proportion of tumour volume change = 0.56), particularly at higher (> 400 ml) volumes. There was good correlation between change in tumour volume and WHO criteria in assigning patients to tumour growth, stable disease or tumour response categories. This study suggests that, in clinical trials comparing colorectal liver metastasis treatments, metastasis volume and not PHR should be used to assess extent of disease and the effect of treatment.

    Limited data are currently available to direct treatment recommendations in the management of leptomeningeal metastases (LM). Here we review treatment modalities clinicians should understand in order to manage patients with LM. We first describe our institution's experience with the treatment of LM and use this dataset to frame the discussion of LM management. Between 1999 and 2014, 1361 patients with central nervous system metastases were reviewed, 124 (9.1%) had radiographic evidence of LM, and these patients form the cohort for this analysis. Mean age at diagnosis of LM was 52years. Median survival for the entire cohort was 2.3months. The most common primary malignancies were non-small cell lung cancer (25.8%), breast cancer (17.7%), small cell lung cancer (16.9%) and melanoma (8.9%). Univariate analyses demonstrated that greater Karnofsky Performance Status (KPS) (p=0.001) and administration of systemic chemotherapy (p<0.001) resulted in improved median survival. Multivariate Cox analyses revealed that receipt of chemotherapy and a complete course of whole brain radiotherapy (WBRT) (median dose 30Gy in 10 fractions, range 24-40Gy) were predictive of longer survival, (p=0.013 and 0.019, respectively). These data suggest that there is a group of patients with good KPS who may experience significantly longer median survival than expected. Multivariate analysis from this single institution retrospective study demonstrated a benefit for WBRT and chemotherapy in individuals with good KPS. These findings provide contemporary data from a large cohort of LM patients, which may be utilized to guide treatment recommendations, assist in patient counseling and direct future investigations into optimization of treatment regimens.

    Cancer of unknown primary (CUP) is a fatal disease diagnosed through metastases. It shows intriguing familial clustering with certain defined primary cancers. Here we examine whether metastatic location in CUP patients is related to primary non-CUP cancers in relatives based on the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for CUP patients defined by metastatic location depending on cancer in their first degree relatives. SIRs for CUP were high in association with liver (3.94), ovarian (3.41), lung (2.43) and colorectal cancers (1.83) in relatives. The SIR was 1.63 for CUP with metastases in the abdomen when a relative was diagnosed with ovarian cancer. CUP with liver metastases associated with liver (1.44) cancer in relatives. CUP with head and neck region metastases associated with relatives’ esophageal (2.87) cancer. CUP metastases in the thorax associated with a relative’s cancers in the upper aerodigestive tract (2.14) and lung (1.74). The findings, matching metastatic location in CUP and primary cancer in relatives, could be reconciled if these cases of CUP constitute a phenotypically modified primary lacking tissue identification, resulting from epitope immunoediting. Alternatively, CUP metastases arise in a genetically favored tissue environment (soil) promoting growth of both primary cancers and metastases (seeds). PMID:26956545

    CNS metastases are the most common cause of malignant brain tumours in adults. Historically, patients with brain metastases have been excluded from most clinical trials, but their inclusion is now becoming more common. The medical literature is difficult to interpret because of substantial variation in the response and progression criteria used across clinical trials. The Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) working group is an international, multidisciplinary effort to develop standard response and progression criteria for use in clinical trials of treatment for brain metastases. Previous efforts have focused on aspects of trial design, such as patient population, variations in existing response and progression criteria, and challenges when incorporating neurological, neuro-cognitive, and quality-of-life endpoints into trials of patients with brain metastases. Here, we present our recommendations for standard response and progression criteria for the assessment of brain metastases in clinical trials. The proposed criteria will hopefully facilitate the development of novel approaches to this difficult problem by providing more uniformity in the assessment of CNS metastases across trials.

    Gastrointestinal stromal tumors (GISTs) rarely metastasize to the skin. We describe 5 patients with GIST with subcutaneous and cutaneous metastases. The mean age at metastasis was 54 years (range 30-68 years) with a male predominance (4:1). Primary tumors occurred in the stomach (n = 3), small bowel (n = 1), and abdomen, not otherwise specified (n = 1). The average time from primary tumor resection to the resection of skin metastases was 59 months (range 11-155 months). The metastases occurred in the scalp (n = 2), cheek (n = 1), and abdomen (n = 2) with 3 patients presenting with solitary nodules and 2 patients with multiple nodules. The average size was 2 cm (range 0.6-4 cm). Histologically, 2 cases were spindled and 3 cases demonstrated mixed epithelioid and spindle cell morphology. All were confirmed to have CD117 reactivity. KIT genotyping was performed in 4 of 5 cases. Two cases harbored a mutation in exon 11, and the remaining 2 cases were wild type in exons 9, 11, 13, and 17. All 5 patients had multiple concurrent or subsequent abdominal and/or hepatic metastases. In 4 patients with an average follow-up of 32 months (range 6-75 months), after the resection of the metastases, 2 were alive with disease and 2 died of disease. Cutaneous metastases seem to be a late complication of GIST, but their presence does not necessarily herald a rapid demise of the patient. PMID:19384074

    Lung metastasis is frequent in rectal cancer patients and has a poor prognosis, with an expected three-year survival rate of about 10%. Though western medicine has made great strides in the curative resection of liver metastases, resection of lung metastases has lagged far behind. Many preclinical studies have suggested that herbal treatments block metastasis, but few clinical studies have addressed this topic. We present the case of a 57-year-old Asian male with lung metastases from rectal cancer. He first underwent resection of the primary lesion (stage IIA, T3N0M0) and six cycles of adjuvant chemotherapy. Unfortunately, lung metastases were confirmed about one year later. Palliative chemotherapy was begun, but his disease continued to progress after three cycles and chemotherapy was halted. The patient was exclusively treated with herbal medicine-standardized allergen-removed Rhus verniciflua stokes extract combined with Dokhwaljihwang-tang (Sasang constitutional medicine in Korea). After seven weeks of herbal medicine treatment, the lung metastases were markedly improved. Regression of lung metastases has continued; also, the patient's rectal cancer has not returned. He has been receiving herbal medicine for over two years and very few side effects have been observed. We suggest that the herbal regimen used in our patient is a promising candidate for the treatment of lung metastases secondary to rectal cancer, and we hope that this case stimulates further investigation into the efficacy of herbal treatments for metastatic colorectal cancer patients.

    We conducted a large, multicenter, retrospective survey aimed to explore the impact of tumor bone involvement in Non-Small Cell Lung Cancer.Data on clinical-pathology, skeletal outcomes and bone-directed therapies for 661 deceased patients with evidence of bone metastasis were collected and statistically analyzed. Bone metastases were evident at diagnosis in 57.5% of patients. In the remaining cases median time to bone metastases appearance was 9 months. Biphosphonates were administered in 59.6% of patients. Skeletal-related events were experienced by 57.7% of patients; the most common was the need for radiotherapy. Median time to first skeletal-related event was 6 months. Median survival after bone metastases diagnosis was 9.5 months and after the first skeletal-related event was 7 months. We created a score based on four factors used to predict the overall survival from the diagnosis of bone metastases: age >65 years, non-adenocarcinoma histology, ECOG Performance Status >2, concomitant presence of visceral metastases at the bone metastases diagnosis. The presence of more than two of these factors is associated with a worse prognosis.This study demonstrates that patients affected by Non-Small Cell Lung Cancer with bone metastases represent a heterogeneous population in terms of risk of skeletal events and survival.

    About 10% of all cancer patients will develop brain metastases during advanced disease progression. Interestingly, the vast majority of brain metastases occur in only three types of cancer: Melanoma, lung and breast cancer. In this review, we focus on summarizing the prognosis and impact of surgical resection of brain metastases originating from gastrointestinal cancers such as esophageal, gastric, pancreatic and colorectal cancer. The incidence of brain metastases is <1% in pancreatic and gastric cancer and <4% in esophageal and colorectal cancer. Overall, prognosis of these patients is very poor with a median survival in the range of only months. Interestingly, a substantial number of patients who had received surgical resection of brain metastases showed prolonged survival. However, it should be taken into account that all these studies were not randomized and it is likely that patients selected for surgical treatment presented with other important prognostic factors such as solitary brain metastases and exclusion of extra-cranial disease. Nevertheless, other reports have demonstrated long-term survival of patients upon resection of brain metastases originating from gastrointestinal cancers. Thus, it appears to be justified to consider aggressive surgical approaches for these patients. PMID:25247579

    Background Bevacizumab is effective for the treatment of non-small cell lung cancer (NSCLC). Ongoing trials are exploring the safety of bevacizumab in patients with inactive, previously treated brain metastases. However, bevacizumab safety and efficacy in the treatment of active brain metastases is unknown. Bevacizumab received accelerated FDA approval for progressive glioblastoma, a primary brain tumor, because of high response rates and low incidence of intracranial hemorrhage. Methods We retrospectively identified patients treated with bevacizumab for active (treatment naïve or progressive) central nervous system (CNS) metastases from NSCLC. MRI scans performed at least 6 weeks after initiating bevacizumab were assessed for response. Results There were six patients, four women and two men with a median age of 60 years (range 59–77) at initiation of bevacizumab. Five patients had progressive CNS metastases despite prior treatment including surgery, radiotherapy, and/or chemotherapy; one patient had treatment-naïve brain metastases. Two patients had leptomeningeal metastases, isolated or coexistent with parenchymal brain metastases in one patient each. Bevacizumab was administered alone to one patient and in combination with various cytotoxic chemotherapies in the others. Toxicity included an asymptomatic (Grade 1) intra-tumoral hemorrhage which occurred in one of three patients receiving concurrent anticoagulation with bevacizumab. There was no recurrent CNS bleeding in two patients with a prior history of such hemorrhage. Best response (RECIST) was partial in two, stable disease in three, and progression in one. Median progression-free survival (PFS) was 4.7 months and median overall survival (OS) was 14.1 months following initiation of bevacizumab. Clinical benefit was also observed in the form of improved symptoms and reduced corticosteroid requirements. Conclusions Bevacizumab should be used with caution in patients with active CNS metastases pending

    Introduction The 19th Annual Meeting of the Society for Neuro-Oncology (SNO) took place in November of 2014. The focus of many abstracts, as well as the Education Day, was on recent advances in the study of central nervous system (CNS) metastases. Tumor Biology Key studies evaluating the factors in tumors and their microenvironment associated with the development and growth of brain metastases are reviewed. Prognostication Studies investigating the factors that independently influence survival in participants with brain metastases are presented. Response Assessment The Response Assessment for Neuro-Oncology criteria for brain metastases (RANO-BM) and the Neurological Assessment in Neuro-Oncology (NANO) criteria, which were both presented, are recapped. Radiotherapy Studies are reviewed evaluating factors that influence survival outcomes in participants with brain metastases who were treated with radiotherapy. Studies investigating the potential risk of radiation necrosis with the combination of radiotherapy and immunotherapies are presented. Systemic Therapies Brain metastases-focused subset analyses from the ASCEND-1 trial for ALK-translocated non–small cell lung cancer are presented. Preclinical and clinical work on solid tumor leptomeningeal carcinomatosis is also covered. Sequelae of Central Nervous System Metastases and Their Treatments An overview is provided of treatment- related toxicities as well as important concepts that may influence strategies to protect against these toxicities. Conclusions Key concepts regarding tumor biology, prognostication, response assessment, therapeutic management, and sequelae of treatment for CNS metastases are summarized. Advances in our understanding of the basic and clinical science of CNS metastases have the potential to improve outcomes for patients.

    Pancreatic metastases are rare, ranging from 2% to 5% of pancreatic malignancies. Differentiating a primary pancreatic malignancy from a metastasis can be difficult due to similarities on imaging findings, but is crucial to ensure proper treatment. Although transabdominal ultrasound, computed tomography, and magnetic resonance imaging provide useful images, endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is often needed to provide a cytologic diagnosis. Here, we present a unique case of malignant melanoma with pancreatic metastases. It is important for clinicians to recognize the possibility of melanoma metastasizing to the pancreas and the role of EUS with FNA in providing cytological confirmation. PMID:26020050

    Carcinoma of the prostate often metastasizes to the skeletal system, the usual radiologic pattern being widespread patchy areas of increased density without change in the contour of the involved bones. Radionuclide correlation generally shows multiple foci of increased tracer activity. Less commonly, there is bony sclerosis with expansion of the diameter of the involved bone. Several cases of expansile skeletal metastases from carcinoma of the prostate have appeared in the literature but we know of no published descriptions of the radionuclide findings. We present three patients with carcinoma of the prostate who had skeletal metastases with evidence of bony expansion on both roentgenographic and radionuclide examination. 15 references, 8 figures.

    Diffuse-type tenosynovial giant cell tumor (D-TGCT) is a relatively rare mesenchymal tumor. It is a locally aggressive but virtually nonmetastasizing neoplasm and thus regarded as benign. Only a few D-TGCTs with benign histology have been reported to metastasize. We report an extremely rare case of benign D-TGCT in which multiple metastases developed 9 years after surgery for the primary tumor. The present case suggests that conventional D-TGCT has the potential to form distant metastases, albeit exceptionally rarely, and that this probable implantation phenomenon can be managed conservatively.

    We report a case of hepatocellular carcinoma (HCC) with multiple lymph node (LN) metastases. A 68-year-old man underwent hepatectomy at our hospital. Intrahepatic recurrence and swelling of multiple LNs were detected by enhanced CT 21 months later. FDG-PET was positive for multiple swollen LNs, but all were negative for the intrahepatic recurrences. Biopsy of para-aortic LNs was revealed LN metastases from HCC. Immunohistochemically, the LN metastases were composed of poorly differentiated HCC. The sensitivity of FDG-PET in patients with HCC varies in relation to degree of differentiation and decreased FDG uptake must be noted. PMID:23132040

    Aim The aim of this study was to report a case of metastatic uveal melanoma in which radioembolized nodular liver metastases decreased in size while infiltrative sinusoidal metastases progressed, leading to jaundice without obstruction of the biliary ducts. Methods The relevant clinical features, imaging, and histopathologic findings of this case are reviewed. Results A 61-year-old Caucasian male with a history of uveal melanoma of the left eye status post plaque brachytherapy developed numerous liver metastases. After progression on systemic therapies, he underwent palliative radioembolization. Despite some radiographic improvement in the liver metastases, he developed hyperbilirubinemia without biliary tract obstruction or signs of liver failure. A biopsy of radiographically normal liver demonstrated extensive sinusoidal infiltration with melanoma. Conclusions Distinct angiographic and histopathologic growth patterns of metastatic uveal melanoma differ in their amenability to radioembolization. Sinusoidal infiltration may lead to hyperbilirubinemia in the absence of overt obstruction or liver failure. PMID:27239458

    We have previously reported that abdominal irradiation prior to i.v. injection of syngeneic tumor cells reduced metastases in lung. Our report described an investigation of the significance of intestinal organisms in the radiation effect. We found that eliminating intestinal organisms with antibiotics totally abolished the radiation effect. Monoassociation of germ-free mice revealed that the radiation effect was observable only for Enterobacter cloacae, never for Streptococcus faecium, Bifidobacterium adlesentis, or Escherichia coli. After abdominal irradiation of regular mice, E. cloacae multiplied in cecal contents, adhered to mucous membranes, invaded the cecal wall, and translocated to mesenteric lymph nodes. Intravenous administration of E. cloacae in place of abdominal irradiation inhibited metastases. E. cloacae-monoassociated mice developed fewer metastases than germ-free mice, and the reduction was further enhanced by abdominal irradiation. We concluded that abdominal irradiation caused the invasion of E. cloacae from the mucous membrane of the intestine and inhibited formation of lung metastases.

    Neuroendocrine tumors (NET) are a heterogeneous group of cancers, with indolent behavior. The most common primary origin is the gastro-intestinal tract but can also appear in the lungs, kidneys, adrenals, ovaries and other organs. In general, NET is usually discovered in the metastatic phase (40%-80%). The liver is the most common organ involved when metastases occur (40%-93%), followed by bone (12%-20%) and lung (8%-10%).A number of different therapeutic options are available for the treatment of hepatic metastases including surgical resection, transplantation, ablation, trans-arterial chemoembolization, chemotherapy and somatostatin analogues. Recently, molecular targeted therapies have been used, usually in combination with other treatment options, to improve outcomes in patients with metastases. This article emphasizes on the role of surgery in the treatment of liver metastases from NET. PMID:25339822

    Skeletal muscle metastases are very rare events in colorectal carcinoma. By contrast, dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous manifestations and a well-recognized association with several human malignancies and, among others, colorectal cancer. Here, we report the case of a 71-year-old woman with paraneoplastic dermatomyositis followed by the development of a metastatic colon cancer. Interestingly, this patient developed multiple skeletal metastases which were preceded by the worsening of systemic symptoms of dermatomyositis. This observation suggests that, while muscle tissue is usually resistant to the development of tumor metastases, the inflammatory and immune response which characterizes and boosts paraneoplastic myopathy may represent a favorable soil for tumor cell invasion and metastasization to skeletal muscles.

    Cancers prone to spread to bone include prostate, lung, kidney, breast and thyroid cancers. While bone scanner has been widely used in the past decades, PET-based imaging modalities are increasingly used. Current modalities of PET imaging of bone metastases include tumor and inflammatory targeting with FDG-PET, bone imaging with NaF-PET, and direct cancer-specific markers such as FDOPA-PET or PET using choline. The cancer-specific metastatic patterns and the relative prognosis conferred by osseous metastases (versus visceral metastases) may determine the need for bone scan, FDG-PET for the detection of bone metastases. Because some cancers have a mixed skeletal and visceral, cocktails PET radiopharmaceuticals may also be discussed in the future. The cancer-specific context and performances of bone scan and PET imaging are discussed. PMID:24153039

    Colorectal cancer (CRC) is an emerging health problem in the Western World both for its raising tendency as well as for its metastatic potential. Almost half of the patients with CRC will develop liver metastases during the course of their disease. The liver surgeon dealing with colorectal liver metastases faces several surgical dilemmas especially in the setting of the timing of operation. Synchronous resectable metastases should be treated prior or after induction chemotherapy? Furthermore in the case of synchronous colorectal liver metastases which organ should we first deal with, the liver or the colon? All these questions are set in the editorial and impulse for further investigation is put focusing on multidisciplinary approach and individualization of treatment modalities. PMID:27275088

    Bone is one of the most common sites of metastatic spread of malignancy, with possible deleterious effects including pain, hypercalcemia, and pathologic fracture. External beam radiotherapy (EBRT) remains the mainstay for treatment of painful bone metastases. Diffusion-weighted MRI (DW-MRI) has been described as an efficient method to differentiate good and poor responders to radiotherapy in bone metastases patients. The addition of DWI to conventional whole-body MRI sequences enhanced lesion conspicuity and improved diagnostic accuracy. We evaluate bone metastases patients with bone scintigraphy and DW-MRI. With technical optimization, whole-body MRI with DWI, as a nonionizing imaging modality, may potentially be useful as an alternative method to bone scintigraphy in the management of bone metastases.

    144 patients with a carcinoma of the upper airways and digestive tract were examined at necropsy in the Institut Bordet, between January 1, 1960 and December 31, 1973. The study shows that 43% of these patients had distant metastases and that among these 2/3 were in local recurrence. Only 1/4 of the metastases had been recognized before death: most of them appearing in the first year following the diagnosis of the primary tumor. Survival of patients with metastases is short, most of them dying within 3 months after metastatic discovery. There seems to be no evident relationship between the initial degree of extension of the tumor and the risk of later metastatic dissemination. In the search for the most frequent metastases, located in the lungs, liver and skeleton, one should use pulmonary laminography and liver tests combined to scanning and laparoscopy. PMID:1258591

    We report a case of a 52-year-old Caucasian man with invasive ductal carcinoma of the breast. One year after initial diagnosis, he developed a generalised epileptic seizure and neuroimaging showed multiple, calcified intracerebral lesions. Owing to these atypical cerebral imaging findings, comprehensive serological and cerebrospinal fluid analysis was conducted and a latent toxoplasmosis was suspected. In order to distinguish between metastases and an infectious disease, a cerebral biopsy was performed, which verified brain metastases. The patient received whole-brain radiotherapy. The last cerebral CT scan, 18 months later showed stable disease. Calcification of brain metastases in patients with breast cancer is very rare. Owing to their non-characteristic radiological appearance with a lack of contrast enhancement, diagnosis of metastases can be difficult. Infectious diseases should be considered within the diagnostic work up. Owing to possible pitfalls, we recommend a widespread differential diagnostic work up in similar cases, and even in cases with a confirmed primary tumour. PMID:26472289

    Ga prostate-specific membrane antigen (PSMA)-HBED-CC PET/CT in a patient with a history of both prostate cancer (PC) and renal cell cancer (RCC) shows high PSMA expression in the residual right seminal vesicle suggestive of local recurrence of PC as well as suspected PSMA-positive mediastinal, retroperitoneal, and iliac lymph nodes. Regarding the latter, biopsy revealed lymph node metastases from RCC excluding PC metastases. This case exemplarily demonstrates that high PSMA expression in RCC metastases can potentially mimic PC metastases. Thus, for accurate interpretation of imaging results in PC patients with additional primary tumors, knowledge of PSMA expression of non-PC tissue is necessary. PMID:26859205

    For treatment of colorectal liver metastases, liver resection is recommended for resectable cases in the clinical guidelines for colorectal cancer. On the other hand, there are currently no data supporting the efficacy of radiation therapy as a topical treatment, and this treatment can therefore not presently be recommended. With CyberKnife®, it is possible to perform stereotactic radiation therapy using a linear accelerator with high accuracy, even for lesions in the trunk area such as liver metastases. Between December 2009 and September 2014 in our hospital, we performed radiation treatment using CyberKnife® for 14 cases with 22 colorectal liver metastases. As a result, we obtained response and local control rates of 76.2%and 81.0%, respectively. Moreover, no advanced adverse events were observed. Thus, we consider that CyberKnife® treatment for colorectal liver metastases is effective as a topical treatment, with low invasiveness and high safety. PMID:26489566

    Summary In prostate to bone metastases, the “vicious cycle” paradigm has been traditionally used to illustrate how metastases manipulate the bone forming osteoblasts and resorbing osteoclasts in order to yield factors that facilitate the growth and establishment. However, recent advances have illustrated that the cycle is far more complex than this simple interpretation. In this review, we will discuss the role of exosomes and hematopoietic/mesenchymal stem cells facilitate the establishment and activation of prostate metastases and, how cells including such as myeloid derived suppressor cells, macrophages, T-cells and nerve cells contribute to the momentum of the vicious cycle. The increased complexity of the tumor-bone microenvironment requires a systems level approach. The evolution of computational models to interrogate the tumor-bone microenvironment is also discussed and the application of this integrated approach should allow for the development of effective therapies to treat and cure prostate to bone metastases.

    Prevalence of brain metastases is increasing in breast cancer. Brain metastases represent a poor-prognosis disease for which local treatments continue to play a major role. In spite of the presence of a physiological blood-brain barrier limiting their activity, some systemic treatments may display a significant antitumor activity at the central nervous system level. In HER2-positive metastatic breast cancer with brain metastases not previously treated with whole brain radiotherapy, capecitabine and lapatinib combination obtains a volumetric reponse in two thirds of patients (LANDSCAPE study). If confirmed, these results could modify in selected patients the layout of therapeutic strategies. Promoting novel targeted approaches and innovative therapeutic combinations is a critical need to improve survival of breast cancer patients with brain metastases. PMID:23305997

    Adrenal gland metastases are common in lung cancer. It is well recognized that aggressive treatment of solitary adrenal metastases leads to improved outcomes but the exact nature of adrenal deposits is not well understood. Controversy exists as to the routing of cancer cells to the adrenal gland with some believing that this transmission is lymphatic, in contrast to the more generally accepted theory of hematogenous spread. Recently published mathematical modeling of cancer progression strongly supports the lymphatic theory. With that in mind, we performed a literature review to look for biological plausibility of simulation results and believe that evidence supports the contention that metastases to the adrenal gland can be routed by means of lymphatic channels. This could explain improved survival for patients in whom solitary adrenal metastases are managed aggressively with surgical or radiation modalities. We are calling for clinical trials prospectively testing this hypothesis. PMID:24736064

    The bones are the most common location for metastases, which may cause severe pain and damage, including osteolytic destruction and fractures. Pathological fractures of the spine are extremely painful and cause significant disability and morbidity in patients. Traditional open surgery has numerous complications, and radiation therapy may take weeks to become effective. To avoid the trauma and complication of open surgery, percutaneous kyphoplasty (PKP) is a minimally invasive procedure that has played a great role in the treatment of spinal metastases over the past several years. To evaluate the efficacy and safety of the treatment of spinal metastasis using PKP, the present study evaluated 282 patients who had received PKP between April 2009 and June 2014. The efficacy of PKP was evaluated using the visual analog scale for pain (VAS), Karnofsky performance score (KPS) and quality of life (QOL) score (short form with 36 questions). The KPS and QOL were measured pre-operatively and 3 months post-operatively. In addition, radiographical data, including the degree of restoration of the kyphotic angle and the anterior vertebral height, and leakage of bone cement, were measured. The safety of the surgery was assessed by complications and side effects reported during or subsequent to surgery. The present study measured the parameters prior to the surgery and at 24 h, 3 months, 6 months and 1 year post-surgery, as well as at the last follow-up date. The range of the follow-up time was between 105 days and 15 months (mean, 401 days). The 282 patients underwent successful operations and the pain felt by the patients prior to the surgery was significantly alleviated. In addition, the analgesic intake of patients greatly decreased following PKP. KPS improved prior to and 3 months after the surgery. QOL also improved prior to and 3 months after the surgery. Radiographical data demonstrated that the kyphotic angle decreased following PKP, and the anterior vertebral height

    Purpose: The purpose of the present study was to compare the prognostic indexes (PIs) of patients with brain metastases (BMs) treated with whole brain radiotherapy (WBRT) using an artificial neural network. This analysis is important, because it evaluates the prognostic power of each PI to guide clinical decision-making and outcomes research. Methods and Materials: A retrospective prognostic study was conducted of 412 patients with BMs who underwent WBRT between April 1998 and March 2010. The eligibility criteria for patients included having undergone WBRT or WBRT plus neurosurgery. The data were analyzed using the artificial neural network. The input neural data consisted of all prognostic factors included in the 5 PIs (recursive partitioning analysis, graded prognostic assessment [GPA], basic score for BMs, Rotterdam score, and Germany score). The data set was randomly divided into 300 training and 112 testing examples for survival prediction. All 5 PIs were compared using our database of 412 patients with BMs. The sensibility of the 5 indexes to predict survival according to their input variables was determined statistically using receiver operating characteristic curves. The importance of each variable from each PI was subsequently evaluated. Results: The overall 1-, 2-, and 3-year survival rate was 22%, 10.2%, and 5.1%, respectively. All classes of PIs were significantly associated with survival (recursive partitioning analysis, P < .0001; GPA, P < .0001; basic score for BMs, P = .002; Rotterdam score, P = .001; and Germany score, P < .0001). Comparing the areas under the curves, the GPA was statistically most sensitive in predicting survival (GPA, 86%; recursive partitioning analysis, 81%; basic score for BMs, 79%; Rotterdam, 73%; and Germany score, 77%; P < .001). Among the variables included in each PI, the performance status and presence of extracranial metastases were the most important factors. Conclusion: A variety of prognostic models describe the

    Purpose: To examine the outcomes of patients with five or more brain metastases treated in a single session with stereotactic radiosurgery (SRS). Methods and Materials: Sixty-four patients with brain metastases treated with SRS to five or more lesions in a single session were reviewed. Primary disease type, number of lesions, Karnofsky performance score (KPS) at SRS, and status of primary and systemic disease at SRS were included. Patients were treated using dosing as defined by Radiation Therapy Oncology Group Protocol 90-05, with adjustments for critical structures. We defined prior whole-brain radiotherapy (WBRT) as WBRT completed >1 month before SRS and concurrent WBRT as WBRT completed within 1 month before or after SRS. Kaplan-Meier estimates and Cox proportional hazard regression were used to determine which patient and treatment factors predicted overall survival (OS). Results: The median OS after SRS was 7.5 months. The median KPS was 80 (range, 60-100). A KPS of {>=}80 significantly influenced OS (median OS, 4.8 months for KPS {<=}70 vs. 8.8 months for KPS {>=}80, p = 0.0097). The number of lesions treated did not significantly influence OS (median OS, 6.6 months for eight or fewer lesions vs. 9.9 months for more than eight, p = nonsignificant). Primary site histology did not significantly influence median OS. On multivariate Cox modeling, KPS and prior WBRT significantly predicted for OS. Whole-brain radiotherapy before SRS compared with concurrent WBRT significantly influenced survival, with a risk ratio of 0.423 (95% confidence interval 0.191-0.936, p = 0.0338). No significant differences were observed when no WBRT was compared with concurrent WBRT or when the no WBRT group was compared with prior WBRT. A KPS of {<=}70 predicted for poorer outcomes, with a risk ratio of 2.164 (95% confidence interval 1.157-4.049, p = 0.0157). Conclusions: Stereotactic radiosurgery to five or more brain lesions is an effective treatment option for patients with

    Purpose: To evaluate feasibility and patterns of failure in adult patients with Ewing sarcoma (ES) treated with whole lung irradiation (WLI) for pulmonary metastases. Methods and Materials: Retrospective review of all ES patients treated at age 18 or older with 12-15 Gy WLI for pulmonary metastases at a single institution between 1990 and 2014. Twenty-six patients met the study criteria. Results: The median age at WLI was 23 years (range, 18-40). The median follow-up time of the surviving patients was 3.8 years (range, 1.0-9.6). The 3-year cumulative incidence of pulmonary relapse (PR) was 55%, with a 3-year cumulative incidence of PR as the site of first relapse of 42%. The 3-year event-free survival (EFS) and overall survival (OS) were 38 and 45%, respectively. Patients with exclusively pulmonary metastases had better outcomes than did those with extrapulmonary metastases: the 3-year PR was 45% in those with exclusively lung metastases versus 76% in those with extrapulmonary metastases (P=.01); the 3-year EFS was 49% versus 14% (P=.003); and the 3-year OS was 61% versus 13% (P=.009). Smoking status was a significant prognostic factor for EFS: the 3-year EFS was 61% in nonsmokers versus 11% in smokers (P=.04). Two patients experienced herpes zoster in the radiation field 6 and 12 weeks after radiation. No patients experienced pneumonitis or cardiac toxicity, and no significant acute or late sequelae were observed among the survivors. Conclusion: WLI in adult patients with ES and lung metastases is well tolerated and is associated with freedom from PR of 45% at 3 years. Given its acceptable toxicity and potential therapeutic effect, WLI for pulmonary metastases in ES should be considered for adults, as it is in pediatric patients. All patients should be advised to quit smoking before receiving WLI.

    We present a young woman with ROS1 gene rearranged non-small cell lung cancer (NSCLC) with brain metastases. ROS is a proto-oncogene tyrosine protein kinase. The patient received a partial course of whole brain radiation therapy and experienced a sustained partial response in the brain. We hypothesize that ROS1 rearranged NSCLC brain metastases may be particularly sensitive to radiation therapy. PMID:26159887

    The efficiency of monotherapy with zoledronic acid (Resorba), doxorubicin, and their combination was studied on the model of metastasizing breast carcinoma in BALB/c mice. Doxorubicin monotherapy was accompanied by a significant increase in median survival up to 57 days (vs. 34 and 35 days in control groups); 27% animals survived for 90 days (duration of the study). Bioluminescence area of the primary tumor significantly decreased on days 21 and 28; the total number of visceral metastases also decreased according to magnetic-resonance imaging data. Resorba monotherapy produced no general toxic effect, the median survival increased to 64 days, and 90-day survival was 33%. Imaging techniques (magnetic-resonance imaging, microtomography, bioluminescent analysis) showed that Resorba delayed the development of the primary tumor (regression of luminescence area on days 21 and 28, regression of standardized bioluminescence intensity on day 28) and significantly reduced the number of visceral metastases in comparison with the control. Combination therapy was less effective than monotherapy with the same medications. Median survival was 55 days, 90-day survival was 13%, but magnetic-resonance imaging and bioluminescence analysis after combination therapy also showed delayed growth of the primary tumor and reduced number of visceral metastases. Microtomography revealed bone metastases in ~30% animals of the control group; in experimental groups, no bone metastases were found. The experiment with periosteal (distal epiphysis of the femur) injection of 4T1-Luc2 tumor cells demonstrated pronounced selective effectiveness of Resorba in relation to bone metastases. Monotherapy with Resorba can prevent the development of not only bone, but also visceral metastases of breast cancer. PMID:27590765

    Purpose: To evaluate the outcome and patterns of failure for patients with nodal metastases from melanoma treated with combined-modality therapy. Methods and Materials: Between 1983 and 2003, 466 patients with nodal metastases from melanoma were managed with lymphadenectomy and radiation, with or without systemic therapy. Surgery was a therapeutic procedure for clinically apparent nodal disease in 434 patients (regionally advanced nodal disease). Adjuvant radiation was generally delivered with a hypofractionated regimen. Adjuvant systemic therapy was delivered to 154 patients. Results: With a median follow-up of 4.2 years, 252 patients relapsed and 203 patients died of progressive disease. The actuarial 5-year disease-specific, disease-free, and distant metastasis-free survival rates were 49%, 42%, and 44%, respectively. By multivariate analysis, increasing number of involved lymph nodes and primary ulceration were associated with an inferior 5-year actuarial disease-specific and distant metastasis-free survival. Also, the number of involved lymph nodes was associated with the development of brain metastases, whereas thickness was associated with lung metastases, and primary ulceration was associated with liver metastases. The actuarial 5-year regional (in-basin) control rate for all patients was 89%, and on multivariate analysis there were no patient or disease characteristics associated with inferior regional control. The risk of lymphedema was highest for those patients with groin lymph node metastases. Conclusions: Although regional nodal disease can be satisfactorily controlled with lymphadenectomy and radiation, the risk of distant metastases and melanoma death remains high. A management approach to these patients that accounts for the competing risks of distant metastases, regional failure, and long-term toxicity is needed.

    The prognosis of patients with adrenal metastases from hepatocellular carcinoma (HCC) has been poor, and aggressive treatment of these tumors is mandatory to improve patients' survival. Since adrenalectomy may be difficult to perform after previous surgery of the right liver lobe, other approaches are required to treat the adrenal mass. This report aims at demonstrating the feasibility of CT-guided transhepatic radiofrequency ablation of right adrenal HCC metastases pretreated with chemoembolization in patients unable to undergo surgical resection.

    To evaluate the usefulness and accuracy of Thallium-201 imaging for detecting metastases from thyroid carcinoma, the authors have compared it with radioiodine scans and serum thyroglobulin levels, which are currently the most sensitive technique for detecting and localizing metastases. Of the sixty-nine patients, fifty-three had lymph node, lung and/or bone metastases. All patients were treated for differentiated thyroid carcinoma with various combinations of total thyroidectomy, radioiodine ablation and thyroid hormone. Scintigraphy with Tl-210 chloride was abnormal in 39 of 53 patients (sensitivity 74%), whereas 34 of 47 patients with I-131 (sensitivity 72%). Positive ratio of I-131 was correlated with histological type (93% of follicular type and 48% of papillary), whereas in the results with Tl-201 no correlation with histopathology was seen. In 13 patients with I-131 scan was negative, but in 11 patients Tl-201 scan revealed the presence of non-functioning metastases. The positive ratio of Tl-201 scans was correlated well with the size of metastases tumors (P<0.005). Of 43 patients with metastases whose thyroglobulin levels (Tg) were measured by radioimmunoassay, Tg were elevated more than 20ng/ml in 37 (86%); the remaining 14% were below 20 ng/ml in spite of having functioning metastases. These patients were subsequently to have elevation of Tg (>80ng/ml) during hypothyroidism. These results indicate Tl-201 scans correlate with serum thyroglobulin levels and have the added advantage of detecting and localizing non-functioning metastases which would not be detected by I-131 scans.

    Small bowel neuroendocrine tumors (NETs) are frequently characterized by a strong propensity to metastasize to the liver, mesentery, and peritoneum. However, only a few extra-abdominal metastatic sites have been reported in the published literature. The present paper implicates that primary small bowel NETs may unusually metastasize to the inguinal lymph nodes. Furthermore, we discuss the formidable diagnostic and therapeutic challenges associated with the metastatic NETs. PMID:27555990

    Prostate cancer is mostly diagnosed at an early stage; however, some tumors are diagnosed in a metastatic stage as cancer of unknown primary origin. In order to allow specific treatment in the case of prostate cancer presenting as cancer of unknown primary origin, it is important to determine the tumor origin. Prostate-specific antigen is used as a diagnostic marker for prostate cancer but the expression declines with progression to castration-resistant prostate cancer. Aim of this study was to identify the most informative marker constellation, which is able to detect metastatic prostate cancer at high sensitivity. The widely used prostate cancer markers such as prostate-specific antigen, prostate-specific acid phosphatase, androgen receptor, prostate-specific membrane antigen, prostein, and ETS-related gene were investigated for their sensitivity to detect prostatic origin of metastases. Expression of prostate-specific antigen, prostate-specific acid phosphatase, androgen receptor, prostate-specific membrane antigen, prostein, and ETS-related gene was determined on archived tissue specimens consisting of benign prostatic tissue (n=9), primary prostate cancer (n=79), lymph node metastases (n=58), and distant metastases (n=39) using immunohistochemistry. The staining intensity was categorized as negative (0), weak (1), moderate (2), and strong (3). All markers except ETS-related gene were able to detect at least 70% of lymph node metastases and distant metastases, with prostate-specific antigen, androgen receptor, and prostate-specific membrane antigen having the highest sensitivity (97%, 91%, and 94%, respectively). A further increase of the sensitivity up to 98% and 100% could be achieved by the combination of prostate-specific antigen, prostate-specific membrane antigen, or androgen receptor for lymph node metastases and for distant metastases, respectively. The same sensitivity could be reached by combining prostate-specific membrane antigen and prostein. Our

    Dear Editor, Cutaneous metastases (CM) are detected in about 0.6-10.4% of patients with an internal malignancy (1-3). Excluding melanoma, breast and lung carcinomas are the main source of CM in women and men, respectively (1,4,5). CM can have different clinical features, and a diagnosis of CM is usually suspected before performing a biopsy. However, this can be a pitfall for clinicians when the clinical presentation is not the typical inflammatory nodule or mass. Herein we report 2 cases of cutaneous metastases of breast carcinoma, initially treated as a common skin infection. Case 1 A 51-year-old Caucasian woman presented to our Institute with a four-month history of diffuse and erythematous pustular, lesions on the right arm that were painless and non pruritic (Figure 1). The patient had undergone excision for a breast adenocarcinoma (stage IIIA) 5 years earlier. An initial diagnosis of folliculitis was established, and the patient started systemic and topical antibiotics without any improvement. Based on the clinical features and the patient medical history, we performed a skin biopsy. Pathologically dermal nests of tumor cells, arranged in a glandular-like pattern and involving the perifollicular and follicular areas (Figure 2, Figure 3), were highlighted. The tumor cells were positive to cytokeratin (CK) 7, CK19, and carcinoembryonic antigen (CEA) and negative for CK20, CK5/6, CD10, and thyroid transcription factor-1 (TTF-1) (Figure 4). According to the clinical history and pathology, a final diagnosis of folliculotropic metastatic breast carcinoma was established. Unfortunately, the patient died after 10 months. Case 2 A 61-year old Caucasian woman presented to our Department with a two-month history of pink/violet macular lesions with diffuse telangiectasia on the left breast and arm (Figure 5, Figure 6). Five years earlier she had undergone excision for a breast adenocarcinoma (stage II A). A previous diagnosis of cellulitis had been made, and systemic

    Background. Medulloblastoma, although the most common brain tumor of childhood, is exceedingly rare in adults. These tumors have a propensity for local recurrence and to metastasize along the leptomeninges; however, extraneural metastases are very rare and typically occur in the bone or bone marrow. We have not come across any case in literature of medulloblastoma with mediastinal metastases in an adult. Case Presentation. We report a case of medulloblastoma in a 38-year-old lady who was treated with surgery followed by craniospinal radiation. Ten years later she presented with hoarseness from true vocal cord paralysis. She was diagnosed to have infiltrating metastases of her medulloblastoma to the mediastinum, which was confirmed by biopsy. There was no local recurrence. This was treated with chemotherapy followed by stem cell rescue, and she remained progression free for 2 years. Conclusion. Medulloblastomas are rare in adults and can present with late extraneural metastases following treatment. Although most common reported sites are bone and bone marrow, late metastases to other unexpected areas like the mediastinum are possible too and warrant awareness. This can be treated with chemotherapy followed by high-dose chemotherapy and stem cell rescue in a young patient with good performance status. PMID:26425604

    A 66-year-old man underwent laparoscopic right nephrectomy for renal cell carcinoma (T2b, N0, M1, clear cell, Grade 3). He was treated with targeted therapy for lung metastases after nephrectomy. Despite the targeted therapy, he was paralyzed in the lower half of the body due to the spinal metastases. Therefore, an osteoplastic laminectomy and domelaminectomy for the spinal metastases was performed. The FDG-PET examination, which was performed after the operation, revealed lung, liver, bone, and small intestinal metastases. After a while, he suffered from continuous massive melena. Double balloon enteroscopy revealed a hemorrhagic tumor in the small intestine, and an emergency operation was performed. A partial resection of the small intestine was performed for the 3 tumors. The histopathological diagnosis was small intestinal metastasis from renal cell carcinoma. It is well known that renal cell carcinoma often develops metastases to the lung, bone, and liver. However, small intestinal metastasis from renal cell carcinoma is rare. Although small intestinal metastasis from renal cell carcinoma often accompanies metastases to other organs, a palliative operation might improve the quality of life in patients with symptomatic tumors.

    Metastases rather than primary cancers determine nowadays the survival of patients. One of the most common primary malignancies is colorectal cancer and this type of tumor is characterized by a high tendency to spread metastases to the lung and liver. CD26/DPP4 is a transmembrane molecule with enzymatic functions which cleaves biologically active peptides. Recently, CD26/DPP4 has become the focus of cancer research and it was shown that CD26/DPP4-positive cancer cells display increased metastatic activity. Here, we tested if the CD26/DPP4-inhibitor Vildagliptin suppresses the development and growth of mouse colorectal lung metastases. This inhibitor of CD26/DPP4 was employed on mouse (C57BL/6) colorectal lung metastases, established by intravenous injection of the syngeneic cell line MC38. For mechanistic analysis, a subcutaneous tumor model was used. The treatment with Vildagliptin significantly suppressed both, the incidence and growth of lung metastases. Autophagy markers (LC3, p62, and ATF4) decreased, apoptosis increased (TUNEL, pH3/Ki-76), and the cell cycle regulator pCDC2 was inhibited. In conclusion, we here showed an anti-tumor effect of Vildagliptin via downregulation of autophagy resulting in increased apoptosis and modulation of the cell cycle. We therefore propose Vildagliptin for the evaluation as a new therapeutic approach for the treatment of colorectal cancer lung metastases. PMID:26233333

    Pineoblastoma is a rare malignant tumor of the central nervous system (CNS), which arises from the parenchyma of the pineal gland. It is characterized by aggressive clinical behavior and frequent metastases along the craniospinal axis. Extraneural metastases may occur due to surgical seeding of tumor cells beyond the dura and/or hematogenous spread, ventriculoperitoneal shunting, or through Batson’s plexus. To our knowledge, only six documented cases of intraosseous metastases of pineoblastoma are described in the literature. A 23-year-old female patient presented with clinical and radiological symptoms of a pineal tumor causing secondary hydrocephalus. After initial surgical treatment, chemotherapy, and local radiotherapy with craniospinal irradiation, she developed multiple metastases affecting the anterior skull base, intracranial meninges, frontal bone, and finally, the entire vertebral column. The patient received surgical treatment for the anterior skull base metastasis, repeated irradiation of the neuraxis, radiosurgical and radiotherapeutic procedures, and chemotherapy. The patient survived 57 months after the primary disease manifestation and died of multiple metastases. This presented case is the first known description of metastasis of pineoblastoma in the anterior cranial base. Multiple intracranial metastases were suppressed using CyberKnife radiation treatment and chemotherapy until massive involvement of spinal column occurred. Interestingly, no signs of brain radiation necrosis after repeated radiation treatments were observed, and the patient developed only moderate neurocognitive decline. PMID:26858918

    Central nervous system (CNS) metastases occur in 30% of patients with advanced non-small cell lung cancer (NSCLC). Localized treatments targeting CNS metastases result in delays in systemic therapy administration and are associated with neurocognitive impairment. Nivolumab is an immune check-point inhibitor that is approved as a second-line treatment of NSCLC. Data regarding the intracranial activity of nivolumab is lacking. We retrospectively reviewed the efficacy and safety of nivolumab in five patients with advanced NSCLC and new/progressing intracranial metastases. Intracranial response was assessed by magnetic resonance imaging (MRI) using mRECIST v. 1.1 criteria. All patients had parenchymal brain metastases; two patients had leptomeningeal carcinomatosis diagnosed according to radiological criteria. All patients were asymptomatic and did not require corticosteroids or immediate local therapy. We observed one complete and one partial response in the brain. Stabilization of leptomeningeal carcinomatosis for 10 weeks was achieved in one additional patient. Two patients progressed in the CNS. Time-to-response comprised 5 weeks and 9 weeks; both responses are still ongoing at the time of the report (24+ and 28+ weeks since start of treatment). Systemic responses and intracranial responses were largely concordant. No treatment-related or CNS metastases-related grade≥3 adverse events were observed. Nivolumab might have intracranial activity and favorable safety profile in patients with CNS metastases secondary to NSCLC. Nivolumab CNS activity warrants further evaluation. PMID:27393516

    Purpose: To investigate the need of a margin other than for accuracy reasons in stereotactic radiosurgery (SRS) of brain metastases by means of histopathology. Methods and Materials: Evaluation of 45 patients from two pathology departments having had brain metastases and an autopsy of the brain. Growth patterns were reviewed with a focus on infiltration beyond the metastases boundary and made visible with immunohistochemical staining: the metastasis itself with tumor-specific markers, surrounding normal brain tissue with a glial marker, and a possible capsule with a soft tissue marker. Measurements were corrected by a tissue-shrinkage correction factor taken from literature. Outcomes parameters for infiltration were mean and maximum depths of infiltration and number of measured infiltration sites. Results: In 48 of 76 metastases, an infiltration was present. The largest group of metastases was lung cancer. Small-cell lung cancer (SCLC) and melanoma showed a maximum depth of infiltration of {>=}1 mm, and other histologies <1 mm. For non-small-cell lung cancer (NSCLC), melanoma, and sarcoma, the highest number of infiltrative sites were observed (median, 2; range, 1-8). SCLC showed significantly larger infiltrative growth, compared with other diagnostic groups. In NSCLC, the highest percentage of infiltration was present (70%). Conclusions: Infiltrative growth beyond the border of the brain metastasis was demonstrated in 63% of the cases evaluated. Infiltrative growth, therefore, has an impact in defining the clinical target volume for SRS of brain metastases, and a margin of {approx}1 mm should be added to the visible lesion.

    Objectives: The staging system of the International Union Against Cancer considers tumor deposits to be N1c in patients with no regional lymph node metastasis, but the significance of tumor deposits in patients with regional lymph node metastases is unclear. We investigated the effect of tumor deposits on overall survival in colorectal cancer patients with regional lymph node metastases. Patients and Methods: From 2000 to 2008, 551 patients underwent resections for colorectal cancer at our medical center. We excluded 87 patients who had distant metastases or had received neoadjuvant chemotherapy or radiotherapy from our study and statistically analyzed the remaining 464 patients. Results: Stepwise multivariate Cox proportional hazards analysis in patients with regional lymph node metastases showed only tumor deposits to be significant for overall survival (hazard ratio: 2.813; P = 0.0002). Recurrence was seen in 49.2% of patients with tumor deposits (30/61) compared with 14.4% of patients without them (58/403; P < 0.0001). Tumor deposits did not show the same effect on overall survival as lymph node metastases. Conclusions: Tumor deposits were significantly associated with poorer overall survival in colorectal cancer patients with regional lymph node metastases. The effect of tumor deposits on overall survival was between that of lymph node metastasis and distant metastasis. PMID:25648159

    Background Apart from regional lymph node metastases, systemic metastases occur sporadically in papillary thyroid carcinomas (PTC). The lung and bones are the most frequent localizations. Additionally known but extremely rare locations are metastases of the skeletal muscles, ovaries, submandibular gland, sphenoidal sinus, brain, adrenals, and, as shown in only two previously published cases to date, the pancreas. Summary In this article we report about two additional patients with pancreatic metastases from PTC. There is almost no prior experience about therapeutic approaches to this type of metastases. In both patients distant metastases within the pancreas were successfully removed. Postoperative histology confirmed the diagnoses. Supplemental genetic analysis did not demonstrate a BRAF V600E mutation or expression of a RET/PTC1 rearrangement in one case, but revealed a BRAF V600E mutation in the second case. Surgery avoided impending complications maintaining quality of life. One patient had a tumor-specific survival of 42 months. The other patient has occult disease. Conclusions Our two patients benefited of a calculated aggressive surgical action. Thus, if low perioperative mortality and morbidity can be warranted, surgical measures are justifiable in selected cases. PMID:20025539

    The treatment of lymph node metastases involving the carotid artery is controversial. The aim of the present study was to determine the outcomes of head and neck cancer patients with radiographic carotid artery involvement in neck metastases. A total of 27 patients with head and neck cancer and radiologically diagnosed advanced metastases involving the common carotid artery or internal carotid artery were enrolled. All patients underwent a primary or salvage neck dissection and surgical carotid peeling. The oncological outcome and survival of all patients were analyzed. Loco-regional control was observed in 13 of the 27 patients (48.1%). During follow-up, five patients (18.5%) developed second primaries and 11 (40.7%) developed distant metastases. The survival time was poor independent of regional control. The median overall survival was 1.55 years and disease-free survival was 0.71 year. Radiographic carotid artery involvement in neck metastases in head and neck cancer appears to correlate with a poor long-term prognosis, with a high rate of distant metastases despite loco-regional control.

    Cervical treatment of oral maxillary squamous cell carcinoma (SCC) remains controversial. We determined the metastases incidence and evaluated its predictive factors. Systematic review and meta-analysis was conducted of 23 Chinese and English-language articles retrieved from PubMed, Ovid, Embase, Cochrane Library, China National Knowledge Infrastructure, and Chinese Scientific and Technological Journal databases. Total cervical metastases and occult metastases rate was 32% and 21%, respectively. Positive lymph node detection was likeliest from levels I to III. The maxillary gingival metastases rate was higher than that of the hard palate. Advanced-stage tumors had higher metastatic risk than early-stage tumors. Well-differentiated tumors had a significantly higher metastases rate than medium and poor-differentiation tumors. N0 cases had survival benefit compared with N+ cases. Metastases rate of oral maxillary SCC correlates significantly with T classification and pathological stage. T and N classifications impact outcome significantly. Therefore, levels I to III selective neck dissection is recommended for patients with T3/4 cN0 disease. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2335-E2342, 2016. PMID:26890607

    Brain metastases are an important clinical problem. Few animal models exist for melanoma brain metastases; many of which are not clinically relevant. Longitudinal MRI was implemented to examine the development of tumors in a clinically relevant mouse model of melanoma brain metastases. Fifty thousand human metastatic melanoma (A2058) cells were injected intracardially into nude mice. Three Tesla MRI was performed using a custom-built gradient insert coil and a mouse solenoid head coil. Imaging was performed on consecutive days at four time points. Tumor burden and volumes of metastases were measured from balanced steady-state free precession image data. Metastases with a disrupted blood-tumor barrier were identified from T1-weighted spin echo images acquired after administration of gadopentetic acid (Gd-DTPA). Metastases permeable to Gd-DTPA showed signal enhancement. The number of enhancing metastases was determined by comparing balanced steady-state free precession images with T1-weighted spin echo images. After the final imaging session, ex-vivo permeability and histological analyses were carried out. Imaging showed that both enhancing and nonenhancing brain metastases coexist in the brain, and that most metastases switched from the nonenhancing to the enhancing phenotype. Small numbers of brain metastases were enhancing when first detected by MRI and remained enhancing, whereas other metastases remained nonenhancing to Gd-DTPA throughout the experiment. No clear relationship existed between the permeability of brain metastases and size, brain location and age. Longitudinal in-vivo MRI is key to studying the complex and dynamic processes of metastasis and changes in the blood-tumor barrier permeability, which may lead to a better understanding of the variable responses of brain metastases to treatments.

  3. Global Dormancy of Metastases Due to Systemic Inhibition of Angiogenesis

    Autopsy studies of adults dying of non-cancer causes have shown that virtually all of us possess occult, cancerous lesions. This suggests that, for most individuals, cancer will become dormant and not progress, while only in some will it become symptomatic disease. Meanwhile, it was recently shown in animal models that a tumor can produce both stimulators and inhibitors of its own blood supply. To explain the autopsy findings in light of the preclinical research data, we propose a mathematical model of cancer development at the organism scale describing a growing population of metastases, which, together with the primary tumor, can exert a progressively greater level of systemic angiogenesis-inhibitory influence that eventually overcomes local angiogenesis stimulation to suppress the growth of all lesions. As a departure from modeling efforts to date, we look not just at signaling from and effects on the primary tumor, but integrate over this increasingly negative global signaling from all sources to track the development of total tumor burden. This in silico study of the dynamics of the tumor/metastasis system identifies ranges of parameter values where mutual angio-inhibitory interactions within a population of tumor lesions could yield global dormancy, i.e., an organism-level homeostatic steady state in total tumor burden. Given that mortality arises most often from metastatic disease rather than growth of the primary per se, this finding may have important therapeutic implications. PMID:24465399

    A Phase I and II study has been conducted of the safety and efficacy of /sup 89/Sr (injected i.v. as the chloride) to alleviate bone pain due to osseous metastatic disease. Potential attendant hematologic toxicity was also examined. Thirty-eight patients with pain due to osseous metastases requiring regular narcotic more than twice a day, documented by an abnormal bone scan and radiography, received 45 doses of /sup 89/Sr after informed consent. The performance status (Karnofsky scale) ranged from 20-80%. One patient had complete pain relief while 22 other doses yielded at least a 25% reduction in narcotic requirement lasting at least 1 mo and/or 20% improvement in Karnofsky scale rating. Two patients had marked to complete relief in tumor sites which were not fractured, with no change in fracture pain. Twenty-two did not respond. Response was independent of narcotic requirements, tumor type, or Karnofsky status. No hematologic toxicity occurred. Strontium-89 may be useful as adjuvant therapy for diffuse bone pain, but a double-blind study comparing it to other nonnarcotic modalities is required.

    Intrinsic involvement of bile ducts, by metastatic colorectal adenocarcinoma growing from within or invading the lumen of bile ducts, is not a well recognized pattern of tumor growth. Clinical, radiographic, operative, and histopathologic aspects of 15 patients with intrabiliary colorectal metastases were described. Fourteen patients were explored for possible hepatic resection. Two had jaundice, two radiographic evidence of an intrabiliary filling defect, 10 intraoperative evidence of intrabiliary tumor, and six microscopic evidence of intrabiliariy tumor. Eleven patients underwent hepatic resection. Five of the resected patients developed hepatic recurrence. Four patients were explored for possible repeat resection. One had jaundice, one radiographic evidence of an intrabiliary filling defect, all had intraoperative evidence of intrabiliary tumor, and three microscopic evidence of intrabiliary tumor. Three patients underwent repeat hepatic resection. All patients with preoperative jaundice and radiographic evidence of an intrabiliary filling defect were unresectable. Overall, actuarial five-year survival is 33% for those patients resected versus 0% for those not resected. Intraoperative recognition of intrabiliary tumor at exploration for hepatic resection was more common than clinical, radiographic, or histopathologic recognition. More diligent examination of resected liver tissue by the surgeon and pathologist may increase identification of bile duct involvement and aid in achieving adequate tumor clearance. PMID:10977117

    The occurrence of bone metastases, in particular secondary to breast and prostate cancer, represents a complex medical condition that is debilitating for affected patients. In order to provide an efficient and personalized therapy, an interdisciplinary treatment approach is mandatory; therefore, systemic pharmacological therapy represents a core element of the overall treatment concept. In terms of pathophysiology, the cancer cells cause a massive disturbance of the local bone microenvironment, which as a rule leads to activation of bone resorbing osteoclasts. In addition to bisphosphonates, which can be considered classical antiresorptive agents, the monoclonal receptor activator of nuclear factor-kappa B ligand (RANKL) antibody denosumab has been in use in clinical practice since 2011. The alpha-emitting radioisotope Alpharadin was also recently approved for the treatment of metastatic prostate cancer. This article provides a summary of the most recent knowledge on the pathogenesis of how cancer cells alter the bone microenvironment as well as a review of established and future systemic treatment options.

    Beta-emitting, bone-seeking radiopharmaceuticals, administered systemically, represent a good alternative or adjuvant to external beam radiotherapy for palliation of painful osteoblastic bone metastases. The most frequently used radiopharmaceutical for this purpose is strontium 89, followed by samarium 153 ethylenediaminetetramethylene phosphonate, and infrequently phosphorus 32 orthophosphate. Prior to consideration for radionuclide therapy, recent bone scans should be evaluated in order to determine if the patient has painful osteoblastic lesions likely to respond to therapy. Approximately 70% of patients with prostate and breast cancer will have a reduction in pain in response to radionuclide therapy, beginning within 2 to 4 weeks and lasting between 2 and 6 months. Patients who are expected to live 3 or more months are more likely to benefit than patients with shorter duration life expectancy. Hematosuppression is the chief side effect of radionuclide therapy, with leukopenia and thrombocytopenia more likely to be clinically significant than anemia. Relative contraindications for treatment include osteolytic lesions, pending spinal cord compression or pathologic fracture, preexisting severe myelosuppression, urinary incontinence, inability to follow radiation safety precautions, and severe renal insufficiency.

    Malignant melanoma is the deadliest of skin cancers. Melanoma frequently metastasizes to the brain, resulting in dismal survival. Nevertheless, mechanisms that govern early metastatic growth and the interactions of disseminated metastatic cells with the brain microenvironment are largely unknown. To study the hallmarks of brain metastatic niche formation, we established a transplantable model of spontaneous melanoma brain metastasis in immunocompetent mice and developed molecular tools for quantitative detection of brain micrometastases. Here we demonstrate that micrometastases are associated with instigation of astrogliosis, neuroinflammation, and hyperpermeability of the blood-brain barrier. Furthermore, we show a functional role for astrocytes in facilitating initial growth of melanoma cells. Our findings suggest that astrogliosis, physiologically instigated as a brain tissue damage response, is hijacked by tumor cells to support metastatic growth. Studying spontaneous melanoma brain metastasis in a clinically relevant setting is the key to developing therapeutic approaches that may prevent brain metastatic relapse.

    During the period from July 1977 to June 1980, 75 patients underwent the surgical excision of solitary brain metastases, and 61 of these patients received whole brain radiation. Three patients developed chronic radiation necrosis. In the 3 patients with necrosis, computed tomography suggested recurrent tumor; the histological diagnosis of necrosis only was obtained at operation in 2 of these patients and by autopsy in the third. Radiation damage resulted in the death of 1 patient, a chronic vegetative state in another, and severe neurological deficit in the third. An additional 4 patients had neurological complications probably related to radiation therapy. As the survival of such patients is prolonged by aggressive treatment, the incidence of radiation-induced complications is likely to increase. The optimal dose of radiation necessary to destroy microscopic foci of tumor after the surgical resection of a single brain metastasis is unknown. Because of the significant incidence of damage after radiation as currently delivered, studies using graded, lower doses are indicated.

    Objective: To assess the early complications in the orthopedic treatment of metastatic bone lesions and the factors associated with these complications. Method: There were assessed, retrospectively, 64 patients that underwent surgical treatment for bone metastases, analyzing the complications that occurred in the pre-operative and early post- operative period and associating them with the tumor origin, type of procedure done, the need of blood reposition before the surgery, the need of new surgical procedures and the mortality due to the complications. Results: Early complications in the treatment were observed in 17 (26.6%) patients, of which six (35.2%) ended up dying due to these complications. Regarding the type, 15 (23.8%) cases were due to surgical complications, four (6.3%) clinical and three (4.7%) patients showed clinical and surgical complications. There was no significant difference in the frequency of complications or mortality when assessed the type of reconstruction or affected region. The tumors with a renal origin needed more blood reposition and showed a bigger frequency of complications. Conclusion: The complications occurred in 26.6%. The complications are not related to the kind of treatment performed or to the region affected. The renal origin tumors showed a higher risk of hemorrhage. PMID:27077063

    Background The prognosis of patients with metastatic osteosarcoma remains poor. However, the chance of survival can be improved by surgical resection of all metastases. In this study we investigate the value of serum alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in predicting the presence of metastatic disease at time of diagnosis. Methods Sixty-one patients with histologically confirmed conventional osteosarcoma of the extremity were included in the study. Only 19.7% of cases presented without evidence of systemic spread of the disease. Pre-treatment serum ALP and LDH were analysed in patients with and without skeletal or pulmonary metastases. Results Serum LDH and ALP levels were not significantly different in patients with or without pulmonary metastases (p=0.88 and p=0.47, respectively). The serum LDH and ALP levels did however differ significantly in patients with or without skeletal metastases (p<0.001 and p=0.02, respectively). The optimal breakpoint for serum LDH as a marker of skeletal metastases was 849 IU/L (AUC 0.839; Sensitivity=0.88; Specificity=0.73). LDH >454 IU/L equated to 100% sensitivity for detected bone metastases (positive diagnostic likelihood ratio (DLR)=1.32). With a cut-off of 76 IU/L a sensitivity of 100% was reached for serum ALP predicting the presence of skeletal metastases (positive DLR=1.1). In a multivariate analysis both LDH ≥850 IU/L (odds ratio [OR]=9; 95% confidence interval (CI) 1.8–44.3) and ALP ≥280 IU/L (OR=10.3; 95% CI 2.1–50.5) were predictive of skeletal metastases. LDH however lost its significance in a multivariate model which included pre-treatment tumour volume. Conclusion In cases of osteosarcoma with LDH >850 IU/L and/or ALP >280 IU/L it may be prudent to consider more sensitive staging investigations for detection of skeletal metastases. Further research is required to determine the value and the most sensitive cut-off points of serum ALP and LDH in the prediction of skeletal metastases. PMID

    Extract: Metastasis of the bone is common in two of the major gender-specific malignancies -- breast and prostate cancers. Although both primary breast and prostate cancer are manageable by "classical" therapies such as surgery, irradiation, and chemotherapy, when metastases (secondary cancers) disseminate to the bones these diseases are, by and large, incurable. Metastasis to the bone is implicated in around 70% of prostate and breast cancer deaths. The idea of harnessing the immune system to fight disseminated cancer has proven to be effective in experimental animal models against transplanted tumors. Here, both arms of the immune system, namely, the humoral one characterized by anti-tumor antibodies and the cellular one composed of a type of white blood cell, specifically the cytotoxic T-lymphocytes (CTLs), were found to cause tumor rejection either following immunization of the experimental mice before the tumor inoculations (active-vaccination) or after adoptive transfer of cancer-specific antibodies or CTLs into tumor-bearing mice (passive-vaccination). Encouraged by these results, scientists and clinicians have joined forces in extensive efforts to apply both active and passive vaccination for the immunotherapy of cancer patients. These attempts have flourished over the last fifteen years following the discovery of the first human tumor antigens in melanoma patients. PMID:20704885

    Breast cancers that overexpress the human epidermal growth factor receptor 2 (HER-2) have a predilection to metastasize to the brain. Therapeutic options for brain metastases with systemic therapy remain a challenge in those patients since targeted and chemotherapeutic agents have limited penetration through the blood-brain barrier.

    Purpose To perform the first meta-analysis of the efficacy of skin-directed therapies for cutaneous metastases. Methods MEDLINE, EMBASE, The Cochrane Library, and ClinicalTrials.gov databases were searched for reports of prospective clinical studies published between 1960 and 2013 that assessed the response of skin-directed therapy for cutaneous metastases (47 of 2,955 unique studies were selected). Primary end points of the study were complete and objective response rates. Secondary analyses were preplanned and included subgroup analyses by skin-directed therapy, histology, and recurrence rates. Meta-analyses were performed with random-effect modeling, and extent of heterogeneity between studies was determined with the Cochran Q and I2 tests. Results After applying exclusion criteria, 47 prospective studies of 4,313 cutaneous metastases were assessed. Five skin-directed therapies were identified: electrochemotherapy, photodynamic therapy, radiotherapy, intralesional therapy, and topical therapy. Among all cutaneous metastases, complete response rate was 35.5% (95% CI, 27.6% to 44.3%) and objective response rate was 60.2% (95% CI, 50.6% to 69.0%). Overall recurrence rate was estimated to be 9.2% (95% CI, 3.7% to 21.2%). Melanoma and breast carcinoma comprised 96.8% of all cutaneous metastases studied and had similar objective response rates (54.5% [95% CI, 48.3% to 60.7%] and 54.0% [95% CI, 48.3% to 59.7%], respectively). Grade ≥ 3 toxicity was reported in less than 6% of patients. Conclusion Response to skin-directed therapy for cutaneous metastases is high but heterogeneous across treatment modalities, with low rates of recurrence post-treatment. Treatment was generally well tolerated and conferred improvements in quality of life. Standardization of response criteria for cutaneous metastases and treatment algorithms to optimally use the available skin-directed therapies are needed. PMID:25154827

    Purpose: The majority of patients with brain metastases from melanoma receive whole-brain radiotherapy (WBRT). However, the results are poor. Hypofractionation regimens failed to improve the outcome of these patients. This study investigates a potential benefit from escalation of the WBRT dose beyond the 'standard' regimen 30 Gy in 10 fractions (10x3 Gy). Methods and Materials: Data from 51 melanoma patients receiving WBRT alone were retrospectively analyzed. A dosage of 10x3 Gy (n = 33) was compared with higher doses including 40 Gy/20 fractions (n = 11) and 45 Gy/15 fractions (n = 7) for survival (OS) and local (intracerebral) control (LC). Additional potential prognostic factors were evaluated: age, gender, performance status, number of metastases, extracerebral metastases, and recursive partitioning analysis (RPA) class. Results: At 6 months, OS rates were 27% after 10x3 Gy and 50% after higher doses (p = 0.009). The OS rates at 12 months were 4% and 20%. On multivariate analysis, higher WBRT doses (p = 0.010), fewer than four brain metastases (p = 0.012), no extracerebral metastases (p = 0.006), and RPA class 1 (p = 0.005) were associated with improved OS. The LC rates at 6 months were 23% after 10x3 Gy and 50% after higher doses (p = 0.021). The LC rates at 12 months were 0% and 13%. On multivariate analysis, higher WBRT doses (p = 0.020) and fewer than brain metastases (p = 0.002) were associated with better LC. Conclusions: Given the limitations of a retrospective study, the findings suggest that patients with brain metastases from melanoma receiving WBRT alone may benefit from dose escalation beyond 10x3 Gy. The hypothesis generated by this study must be confirmed in a randomized trial stratifying for significant prognostic factors.

    Purpose: To investigate hypoxia measured by pimonidazole binding, glucose transporter 1 (GLUT1) and carbonic anhydrase IX (CA-IX) expression, proliferation, and vascularity in liver metastases of colorectal cancer and to compare GLUT1 and CA-IX expression in corresponding primary tumors. Methods and Materials: Twenty-five patients with liver metastases of colorectal cancer, planned for metastasectomy, were included. The hypoxia marker pimonidazole and proliferation marker iododeoxyuridine were administered before surgery. After immunofluorescent staining of the frozen metastases, pimonidazole binding, vascularity, and proliferation were analyzed quantitatively. Thirteen paraffin-embedded primary tumors were stained immunohistochemically for GLUT1 and CA-IX expression, which was analyzed semiquantitatively in primary tumors and corresponding liver metastases. Results: In liver metastases, pimonidazole binding showed a pattern consistent with diffusion-limited hypoxia. The mean pimonidazole-positive fraction was 0.146; the mean distance from vessels to pimonidazole-positive areas was 80 {mu}m. When expressed, often co-localization was observed between pimonidazole binding and GLUT1 or CA-IX expression, but microregional areas of mismatch were also observed. No correlation between the level of pimonidazole binding and GLUT1 or CA-IX expression was observed. In some patients, a large fraction (up to 30%) of proliferating cells was present in pimonidazole-stained areas. Expression of CA-IX in primary tumors and metastases showed a significant correlation, which was absent for GLUT1 expression. Conclusions: Compared with other tumor types, liver metastases of colorectal cancer contain large amounts of hypoxic cells. The lack of correlation with pimonidazole binding brings into question the value of GLUT1 and CA-IX as endogenous markers of hypoxia.

    Purpose. To analyze the factors associated with favorable survival in patients with inoperable colorectal lung metastases treated with percutaneous image-guided radiofrequency ablation. Methods. Between 2002 and 2011, a total of 398 metastases were ablated in 122 patients (87 male, median age 68 years, range 29-90 years) at 256 procedures. Percutaneous CT-guided cool-tip radiofrequency ablation was performed under sedation/general anesthesia. Maximum tumor size, number of tumors ablated, number of procedures, concurrent/prior liver ablation, previous liver or lung resection, systemic chemotherapy, disease-free interval from primary resection to lung metastasis, and survival from first ablation were recorded prospectively. Kaplan-Meier analysis was performed, and factors were compared by log rank test. Results. The initial number of metastases ablated was 2.3 (range 1-8); the total number was 3.3 (range 1-15). The maximum tumor diameter was 1.7 (range 0.5-4) cm, and the number of procedures was 2 (range 1-10). The major complication rate was 3.9 %. Overall median and 3-year survival rate were 41 months and 57 %. Survival was better in patients with smaller tumors-a median of 51 months, with 3-year survival of 64 % for tumors 2 cm or smaller versus 31 months and 44 % for tumors 2.1-4 cm (p = 0.08). The number of metastases ablated and whether the tumors were unilateral or bilateral did not affect survival. The presence of treated liver metastases, systemic chemotherapy, or prior lung resection did not affect survival. Conclusion. Three-year survival of 57 % in patients with inoperable colorectal lung metastases is better than would be expected with chemotherapy alone. Patients with inoperable but small-volume colorectal lung metastases should be referred for ablation.

    The authors studied complications associated with intraventricular chemotherapy in patients with leptomeningeal metastases (LM). One hundred twenty consecutive patients with LM (71 females and 49 males) ranging in age from 10 to 72 years (median 42 years) were treated with involved-field radiotherapy and intraventricular chemotherapy using an Ommaya reservoir and intraventricular catheter system. The diagnosis of LM was determined by a combination of clinical presentation (114 patients); cerebrospinal fluid cytological studies (100); or neuroradiographic studies (42). Systemic tumor histological findings included breast (34 patients); non-Hodgkin's lymphoma (22); melanoma (16); primitive neuroectodermal tumors including medulloblastoma (10); glial neoplasms, leukemia, small cell lung, nonsmall cell lung, and colon (six each); prostate and kidney (three each); and gastric cancers (two). Sixteen patients, all with non-Hodgkin's lymphoma, also had acquired immune deficiency syndrome. Patients received one to four (median two) chemotherapeutic drugs and underwent a total of 1110 cycles of intraventricular chemotherapy (median 10). Intraventricular chemotherapy administration and diagnostic Ommaya reservoir punctures totaled 4400, with a median of 46 per patient. Complications included aseptic/chemical meningitis (52 patients); myelosuppression due to intraventricular chemotherapy (21); catheter-related infections (nine); unidirectional catheter obstruction (six); intraventricular catheter malpositioning (two); Ommaya reservoir exposure (two); leukoencephalopathy (two); and chemotherapy-related myelopathy (one). There were no treatment-related deaths; however, seven patients (6%) required additional surgery for either catheter repositioning (two) or reservoir removal (five). Seven patients with catheter-related infections were treated successfully with intraventricular and systemic antibiotic drugs, thereby preserving the Ommaya system. The authors conclude that Ommaya

    Purpose: To review experiences in the treatment of regionally advanced melanoma to the neck and/or parotid with emphasis on the role of adjuvant radiotherapy. Patients and Methods: Clinical and histopathologic data, treatment details, and outcomes in patients treated during the period 2000-2006 at the Institute of Oncology, Ljubljana, Slovenia, were reviewed. Results: A total of 40 patients with 42 dissections underwent surgery, and 43 patients with 45 dissections received irradiation postoperatively to a median equivalent dose (eqTD{sub 2}: 2 Gy/fraction, 1 fraction/day, 5 fractions/week) of 60 Gy (range, 47.8-78.8). Regional control 2 years after surgery was 56% (95% confidence interval [CI] 40-72%) and after postoperative radiotherapy 78% (CI 63-92%) (p = 0.015). On multivariate analysis, postoperative radiotherapy (yes vs. no: hazard ratio [HR] 6.3, CI 2.0-20.6) and sum of the risk factors present (i.e., risk factor score; HR 1.7 per score point, CI 1.2-2.6) were predictive for regional control. On logistic regression testing, the number of involved nodes was associated with the probability of distant metastases (p = 0.021). The incidence of late toxicity did not correlate with the mode of therapy, eqTD{sub 2}, or fractionation pattern. Conclusions: Adjuvant radiotherapy has the potential to compensate effectively for the negative impact of adverse histopatologic features to disease control in a dissected nodal basin. More conventionally fractionated radiotherapy regimens using fraction doses of 2-2.5 Gy, with cumulative eqTD{sub 2{>=}}60 Gy, are recommended. The number of involved lymph nodes is proposed as an additional criterion for limiting the implementation of adjuvant irradiation.

    Bone metastases are responsible for most of the morbidity and mortality associated with solid malignant tumors, occurring in about 65-70% of the patients with advanced breast or prostate cancer. The pathophysiology of skeletal metastasis is a complex process that involves several biologic process leading to cellular invasion, adhesions and stimulation of osteoclasts and osteoblasts with the mediation of several factors including cytokines, serine proteases and tumor-derived factors. The clinical management of pain from bone metastasis, which is mostly due to indirect stimulation of sensory nerve endings by cytokines and other biologically-active compounds released locally in response to the presence of tumor cells in the bone marrow, includes several options that can be used either alone or in varying combinations, such as analgesic drugs, chemo- or hormonal therapy, bisphosponates, external beam radiation therapy, and surgery. Bone-seeking radiopharmaceuticals play an important role in the treatment of pain caused by multiple blastic or mixed-type skeletal lesions; they have in general a favorable toxicity profile and a high rate of overall clinical benefit, although they may differ in terms of duration of pain palliation and suitability for repeat treatments. The palliative effect can be attributed to the radiation targeted to the bone marrow space, and the overall average response ranges between about 45-80%, with complete response in 10-30% of the cases. In selected clinical conditions, radionuclide therapy can also constitute an effective systemic treatment beyond bone pain palliation, and a synergistic anti-tumour effect can be expected by the combination with other agents, such as chemotherapy or bisphosphonates. This review summarizes the current experience with bone-seeking radiopharmaceuticals used for bone pain palliation, focusing on indications, patients' selection, efficacy and toxicity. Finally, the available data on combination therapies showing

    When a patient with cancer develops a brain metastasis, death is usually imminent, but aggressive treatment in some patients with limited or no systemic disease yields long-term survival. In such patients, delayed deleterious effects of therapy are particularly tragic. We report 12 patients who developed delayed complications of whole brain radiotherapy (WBRT) given as sole treatment (4 patients) or in combination with surgical resection (8 patients). Within 5 to 36 months (median, 14) all patients developed progressive dementia, ataxia, and urinary incontinence causing severe disability in all and leading to death in 7. No patient had tumor recurrence when neurologic symptoms began. Cortical atrophy and hypodense white matter were identified by CT in all. Contrast-enhancing lesions were seen in 3 patients; 2 of the lesions yielded radionecrosis on biopsy. Autopsies on 2 patients revealed diffuse chronic edema of the hemispheric white matter in the absence of tumor recurrence. Corticosteroids and ventriculoperitoneal shunt offered significant but incomplete improvement in some patients. The total dose of WBRT was only 2,500 to 3,900 cGy, but daily fractions of 300 to 600 cGy were employed. We believe that these fractionation schedules, several of which are used commonly, predispose to delayed neurologic toxicity, and that more protracted schedules should be employed for the safe and efficacious treatment of good-risk patients with brain metastases. The incidence of WBRT-induced dementia was only 1.9 to 5.1% in the 2 populations reviewed here; however, this underestimates the incidence because only severely affected patients could be identified from chart review.

    Melanin possess radioprotective and scavenging properties, and its presence can affect the behavior of melanoma cells, its surrounding environment and susceptibility to the therapy, as showed in vitro experiments. To determine whether melanin presence in melanoma affects the efficiency of radiotherapy (RTH) we evaluated the survival time after RTH treatment in metastatic melanoma patients (n = 57). In another cohort of melanoma patients (n = 84), the relationship between melanin level and pT and pN status was determined. A significantly longer survival time was found in patients with amelanotic metastatic melanomas in comparison to the melanotic ones, who were treated with either RTH or chemotherapy (CHTH) and RTH. These differences were more significant in a group of melanoma patients treated only with RTH. A detailed analysis of primary melanomas revealed that melanin levels were significantly higher in melanoma cells invading reticular dermis than the papillary dermis. A significant reduction of melanin pigmentation in pT3 and pT4 melanomas in comparison to pT1 and T2 tumors was observed. However, melanin levels measured in pT3-pT4 melanomas developing metastases (pN1-3, pM1) were higher than in pN0 and pM0 cases. The presence of melanin in metastatic melanoma cells decreases the outcome of radiotherapy, and melanin synthesis is related to higher disease advancement. Based on our previous cell-based and clinical research and present research we also suggest that inhibition of melanogenesis can improve radiotherapy modalities. The mechanism of relationship between melanogenesis and efficacy of RTH requires additional studies, including larger melanoma patients population and orthotopic, imageable mouse models of metastatic melanoma.

    BACKGROUND: Metastatic brain tumors are a common complication of systemic cancers. Good performance status, absence of extracranial metastases, age < 65 years and control of the primary tumor are the strongest predictors of survival. Controversy exists regarding best adjuvant treatment for patients. Therefore, careful evaluation of patient features and tumor characteristics must be considered when determining treatment modality. OBJECTIVES: The aim of the study was to assess the treatment management and clinical features of metastatic brain neoplasms following a neurosurgical procedure and evaluate factors conditioning survival. METHODS: Between January 1st 2009 and January 1st 2013, medical files of patients who underwent a surgical procedure for metastatic brain tumors at Hôpital de l'Enfant-Jésus in Québec City were reviewed. Data on patient features, primary and metastatic neoplasm characteristics, procedure and survival were recorded. Wilcoxon rank sum test, Kruskal-Wallis test and Cox proportional-hazards regression for survival data were used to assess the impact of treatments and patient characteristics on survival. Efficacy of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) and combined treatment in terms of patient survival were also evaluated. RESULTS: One hundred and twenty six patient files were reviewed and 109 were included for analysis. The mean survival time for patients was 537.9 days. Age below 65 years (p = 0.08) was a protective factor. WBRT combined with SRS (p < 0.0001), the use of WBRT alone (p = 0.002) or SRS alone (p = 0.004) all significantly improved survival. SRS, when compared to WBRT alone or to combined WBRT and SRS treatment, did not show significant difference in survival. CONCLUSION: Survival in our population is influenced by age and the use of adjuvant treatment. The choice of treatment modality after surgery remains somewhat controversial and our results support the need for further studies to compare

    AIM: To systematically review the available evidence regarding cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) for colorectal peritoneal metastases (CPM). METHODS: An electronic literature search was carried out to identify publications reporting oncological outcome data (overall survival and/or disease free survival and/or recurrence rates) following CRS and IPC for treatment of CPM. Studies reporting outcomes following CRS and IPC for cancer subtypes other than colorectal were only included if data were reported independently for colorectal cancer-associated cases; in addition studies reporting outcomes for peritoneal carcinomatosis of appendiceal origin were excluded. RESULTS: Twenty seven studies, published between 1999 and 2013 with a combined population of 2838 patients met the predefined inclusion criteria. Included studies comprised 21 case series, 5 case-control studies and 1 randomised controlled trial. Four studies provided comparative oncological outcome data for patients undergoing CRS in combination with IPC vs systemic chemotherapy alone. The primary indication for treatment was CPM in 96% of cases (2714/2838) and recurrent CPM (rCPM) in the remaining 4% (124/2838). In the majority of included studies (20/27) CRS was combined with hyperthermic intraperitoneal chemotherapy (HIPEC). In 3 studies HIPEC was used in combination with early post-operative intraperitoneal chemotherapy (EPIC), and 2 studies used EPIC only, following CRS. Two studies evaluated comparative outcomes with CRS + HIPEC vs CRS + EPIC for treatment of CPM. The delivery of IPC was performed using an “open” or “closed” abdomen approach in the included studies. CONCLUSION: The available evidence presented in this review indicates that enhanced survival times can be achieved for CPM after combined treatment with CRS and IPC. PMID:25320542

    2014-01-01

    Background Muscle metastases (MM) from solid tumours are rare. The aim of this study was to describe radiological features of MM, and to compare their patterns in different malignancies. Methods A retrospective search in the statistical database of our institution revealed 61 cases of MM. Additionally, a retrospective search in Pubmed database was performed. Together with our cases the present analysis comprises 461 patients (682 MM). Results MM derived from the following malignancies: lung cancer (25.1%), gastrointestinal tumours (21.0%), and urological tumours (13.2%). Other neoplasias with MM were rare. MM were localised most frequently in the thigh muscles, the extraocular musculature, and the gluteal and paravertebral muscles. The localisation of MM was different in several primary malignancies. On computed tomography (CT), five different patterns of MM occurred: masses with homogeneous contrast enhancement (type I, 46.5%), abscess-like lesions (type II, 27.7%), diffuse infiltration with muscle swelling (type III, 18.1%), intramuscular calcifications (type IV, 6.5%), or MM presented as intramuscular bleeding (type V, 1.2%). MM from several primary tumours manifested with different CT patterns. On MRI, most MM were hyperintense in comparison to unaffected musculature in T2 weighted images and hypo- to isointense on T1 weighted images with a heterogeneous enhancement. There were no differences in MRI features of MM in different primary tumours. On ultrasound, most MM were hypoechoic. On positron emission tomography, MM presented as focally abnormal intramuscular uptake. Conclusion MM present with a broad spectrum of radiological features. Different CT imaging findings of MM were observed in different primary tumours. The localisation of MM also varies with different primary malignancies. PMID:25608474

    Background Breast cancer (BC) is the second most common cause of brain metastases (BM). Optimal management of BM from BC is still debated. In an attempt to provide appropriate treatment and to assist with optimal patient selection, several specific prognostic classifications for BM from BC have been established. We evaluated the prognostic value and validity of the 6 proposed scoring systems in an independent population of BC patients with BM. Methods We retrospectively reviewed all consecutive BC patients referred to our institution for newly diagnosed BM between October 1995 and July 2011 (n = 149). Each of the 6 scores proposed for BM from BC (Sperduto, Niwinska, Park, Nieder, Le Scodan, and Claude) was applied to this population. The discriminative ability of each score was assessed using the Brier score and the C-index. Individual prognostic values of clinical and histological factors were analyzed using uni- and multivariate analyses. Results Median overall survival was 15.1 months (95% CI,11.5–18.7). Sperduto-GPA (P < .001), Nieder (P < .001), Park (P < .001), Claude (P < .001), Niwinska (P < .001), and Le Scodan (P = .034) scores all showed significant prognostic value. The Nieder score showed the best discriminative ability (C-index, 0.672; Brier score error reduction, 16.1%). Conclusion The majority of prognostic scores were relevant for patients with BM from BC in our independent population, and the Nieder score seems to present the best predictive value but showed a relatively low positive predictive value. Thus, these results remain insufficient and challenge the routine use of these scoring systems. PMID:24311640

    Brain metastases (BM) frequently develop in patients with melanoma and are associated with a poor prognosis. Whole brain radiation therapy (WBRT) is a standard intervention for intracranial disease, particularly in patients with multiple BM. Ipilimumab improves survival in patients with advanced melanoma. The purpose of this study is to investigate the safety and efficacy of concurrent WBRT and ipilimumab. A retrospective analysis was conducted of 13 consecutive patients treated with WBRT within 30 days of ipilimumab administration. Radiographic response, as measured by serial magnetic resonance imaging scans post-treatment, was graded by modified World Health Organization (mWHO) and immune-related response criteria (irRC) in the 9 patients with follow-up imaging. Treatment-related toxicity was prospectively assessed during treatment. Four of nine patients (44 %) experienced partial response or stable central nervous system (CNS) disease as measured by mWHO criteria. This number increased to 5 patients (56 %) when irRC criteria were used. Rates of treatment-related neurologic toxicity were low with only one patient experiencing grade 3–4 neurologic toxicity. There was a high rate of intratumoral hemorrhage in this patient population, with 10 of 10 patients with post-treatment imaging demonstrating new or increased intratumoral bleeding after WBRT. This retrospective study demonstrates that the primary pattern of CNS response to WBRT and ipilimumab is stable disease and not regression of BM. Furthermore, while the combination of WBRT and ipilimumab may offer promising efficacy, prospective studies are needed to further assess efficacy and toxicity. PMID:25273687

    Purpose: To evaluate early perfusion changes in normal tissue following stereotactic radiosurgery (SRS). Methods: Nineteen patients harboring twenty-two brain metastases treated with SRS were imaged with dynamic susceptibility magnetic resonance imaging (DSC MRI) at baseline, 1 week and 1 month post SRS. Relative cerebral blood volume and flow (rCBV and rCBF) ratios were evaluated outside of tumor within a combined region of interest (ROI) and separately within gray matter (GM) and white matter (WM) ROIs. Three-dimensional dose distribution from each SRS plan was divided into six regions: (1) <2 Gy; (2) 2-5 Gy; (3) 5-10 Gy; (4) 10-12 Gy; (5) 12-16 Gy; and (6) >16 Gy. rCBV and rCBF ratio differences between baseline, 1 week and 1 month were compared. Best linear fit plots quantified normal tissue dose-dependency. Results: Significant rCBV ratio increases were present between baseline and 1 month for all ROIs and dose ranges except for WM ROI receiving <2 Gy. rCBV ratio for all ROIs was maximally increased from baseline to 1 month with the greatest changes occurring within the 5-10 Gy dose range (53.1%). rCBF ratio was maximally increased from baseline to 1 month for all ROIs within the 5-10 Gy dose range (33.9-45.0%). Both rCBV and rCBF ratios were most elevated within GM ROIs. A weak, positive but not significant association between dose, rCBV and rCBF ratio was demonstrated. Progressive rCBV and rCBF ratio increased with dose up to 10 Gy at 1 month. Conclusion: Normal tissue response following SRS can be characterized by dose, tissue, and time specific increases in rCBV and rCBF ratio. PMID:26269612

    Of ophthalmic involvement from metastatic breast cancer, extraocular/intraorbital metastases are extremely rare. External beam radiotherapy has been a mainstay palliation for symptomatic orbital metastases. We present a case of bilateral orbital metastases from breast cancer successfully treated with stereotactic radiotherapy (SRT). A 38-year-old woman presented with decreased vision in the right eye for 3 weeks. Eight months previously, she underwent whole-brain radiotherapy for multiple brain metastases from breast cancer. Visual acuity was hand motion, and the eyelid closed incompletely in the affected eye. Computed tomography scans showed a 3-cm extraconal mass in the right orbit. She underwent temporary tarsorrhaphy followed by SRT. A total dose of 39 Gy was delivered to the right orbital mass in three daily fractions. Four months later, her visual function was normal in both eyes and the right orbital mass disappeared. A new lesion was detected in the left orbit. She underwent SRT for the left orbital lesion using the same dose-fractionation schedule. No radiation-related toxicities were observed. She died 19 months after the first SRT. Our case suggests that SRT may be an effective and safe treatment option in patients with orbital metastases from breast cancer. PMID:21999613

    The continuous release of bone-stored growth factors following bone resorption promotes the colonization of circulating cancer cells. However, the precise role of each of the various growth factors remains unclear. In this study, we investigated the role of bone-derived insulin-like growth factor (IGF) in the development of bone metastases in an animal model of breast cancer. We found that local stimulation of calvarial bone resorption prior to cell inoculation stimulated subsequent bone metastases to that site in vivo, while inhibition of bone resorption inhibited bone metastases. Anchorage-independent growth of cancer cells was stimulated by the culture supernatants from resorbed bones, which contained elevated levels of IGF type I (IGF-1). This stimulation was blocked by IGF-1 receptor (IGF1R) neutralizing antibody, but not antibody targeting other bone-stored growth factors including TGFβ, fibroblast growth factors, and platelet derived growth factors. While recombinant human IGF-I caused IGFIR tyrosine autophosphorylation, followed by activation of Akt and NF-κB in cancer cells, dominant-negative inhibition of IGFIR, Akt, or NF-κB significantly reduced bone metastases with increased apoptosis and decreased mitosis in metastatic cells. Together, our findings suggest that bone-derived IGF-I bridges the crosstalk between bone and metastasized cancer cells via activation of the IGFIR/Akt/NF-κB pathway. Disruption of this pathway therefore may represent a promising therapeutic intervention for bone metastasis. PMID:22738911

    Neoadjuvant systemic therapy may induce steatosis or sinusoid obstruction syndrome in the liver. The aim of this study was to investigate the influence of systemic therapy with irinotecan, oxaliplatin and cetuximab on conspicuity of liver metastases on computed tomography (CT). CT scans of 48 patients with initial unresectable colorectal liver metastases which were treated in a Europe-wide, opened, randomized phase II trial receiving oxaliplatin or irinotecan combined with folinic acid and cetuximab were analysed. The density of the metastases and the liver parenchyma before and after systemic therapy were analysed by region-of-interest technique and the tumour-to-liver difference (dHU TLD). The mean density of liver parenchyma and liver metastases did not vary significantly before and after neoadjuvant therapy on plain (56.3 ± 8.1 HU, 54.8 ± 13.5 HU) and arterial enhanced CT (76.0 ± 15.7 HU, 70.5 ± 20.4 HU). There was a significant reduction (105.6 ± 17.3 HU, 93.3 ± 18.2 HU) in the density of liver parenchyma on portal venous scans after systemic therapy (p < 0.0001) and a reduction of dHU TLD, consecutively. In patients with colorectal liver metastases, neoadjuvant chemotherapy may have a toxic impact on liver parenchyma resulting in reduced tumour-to-liver contrast in contrast-enhanced CT. This may lead to underestimation of real lesion size. PMID:21771709

    Merkel cell carcinoma (mcc) is a highly aggressive neuroendocrine tumour of the skin. Remission rates are high with chemotherapy in patients with metastasis, but without any improvement in overall survival. We present the case of a 90-year-old woman with facial mcc. After radiation and surgery, the mcc recurred with widespread cutaneous and regional lymph node metastases. The metastases were treated with weekly intralesional injections of 1–2×106 IU interferon alfa-2a, accompanied by topical imiquimod 5% cream 3 times weekly. After partial regression, subcutaneous pegylated interferon alfa-2b was added at a dose of 30 μg weekly, which was then increased to 50 μg weekly. At 4 months after the start of immunotherapy, all cutaneous metastases and the intralesionally treated lymph node metastases receded. Interruption or reduction of systemic interferon application resulted in locoregional relapses that were successfully treated with surgery or intralesional interferon injections. The patient remains alive 30 months after initiation of immunotherapy, suggesting that locally metastasized mcc might be able to be controlled with local and systemic immunotherapy. PMID:27122984

    Purpose: Patients with brainstem metastases have limited treatment options. In this study, we reviewed outcomes after stereotactic radiosurgery (SRS) in the management of patients with brainstem metastases. Methods and Materials: Records were reviewed of 22 consecutive patients presenting with brainstem metastases who underwent SRS. The most frequent primary malignancy was the lung (n = 11), followed by breast (n = 3) and kidney (n = 2). Three patients (14%) also underwent whole-brain radiation therapy (WBRT). The median tumor volume was 0.9 mL (range, 0.1-3.3 mL); the median tumor margin dose was 16 Gy (range, 14-23 Gy). Results: Median survival time after SRS was 8.5 months. Although local tumor control was achieved in all patients with imaging follow-up (n = 19), 5 patients died from development and progression of new brain metastases. Two patients (9%) had symptom improvement after SRS, whereas 1 patient (5%) developed a new hemiparesis after SRS. Conclusions: Radiosurgery is safe and provides a high local tumor control rate for patients with small brainstem metastases. Patients with limited systemic disease and good performance status should be strongly considered for SRS.

    Pain management often is difficult in patients with bone metastases. Metastatic disease represents >40% of oncologic practice, and >70% of patients with metastatic disease have uncontrolled cancer-related pain. Significant morbidity caused by pathologic fracture and spinal cord compression can result from untreated bone metastases. Representing both a manifestation of systemic disease as well as causing localized symptoms, bone metastases require a multidisciplinary therapeutic approach. Radiation therapy provides both localized and systemic treatment options in addition to chemohormonal therapies and surgery. External beam irradiation provides palliation in >70% of patients through tumor regression of a localized lesion. Systemic radiopharmaceuticals treat multifocal disease either alone or as an adjuvant to external beam irradiation. Efficient and comprehensive management of bone metastases is imperative because of the associated symptoms, prior therapies, complex underlying medical problems, and clinical presentations that often require emergent interventions. Intensification of pain may be observed with hormonal therapy and systemic radiopharmaceuticals. Symptomatic relief from antineoplastic therapies generally requires 4-12 weeks and may be related to reossification. Symptoms, occurring due to the disease and/or while awaiting response to therapy, must be aggressively managed. Persistent or recurrent pain after therapy may be due to bony instability or fracture before reossification occurs. An Interdisciplinary Bone Metastases Clinic, with representatives from Diagnostic Radiology, Medical Oncology, Nuclear Medicine, Orthopedic Surgery, Pain and Symptom Management, Physical Medicine and Rehabilitation, and Radiation Oncology, was developed that allows coordinated evaluation, treatment, and symptom management of these complex clinical presentations.

    Stereotactic radiosurgery (SRS) is an established non-invasive ablative therapy for brain metastases. Early clinical trials with SRS proved that tumor control rates are superior to whole brain radiotherapy (WBRT) alone. As a result, WBRT plus SRS was widely adopted for patients with a limited number of brain metastases (“limited number” customarily means 1-4). Subsequent trials focused on answering whether WBRT upfront was necessary at all. Based on current randomized controlled trials (RCTs) and meta-analyses comparing SRS alone to SRS plus WBRT, adjuvant WBRT results in better intracranial control; however, at the expense of neurocognitive functioning and quality of life. These adverse effects of WBRT may also negatively impact on survival in younger patients. Based on the results of these studies, treatment has shifted to SRS alone in patients with a limited number of metastases. Additionally, RCTs are evaluating the role of SRS alone in patients with >4 brain metastases. New developments in SRS include fractionated SRS for large tumors and the integration of SRS with targeted systemic therapies that cross the blood brain barrier and/or stimulate an immune response. We present in this review the current high level evidence and rationale supporting SRS as the standard of care for patients with limited brain metastases, and emerging applications of SRS.

    Introduction Huge hepatocellular carcinoma (HCC) possesses a potential risk for spontaneous rupture, which leads to a life-threatening complication with a high mortality rate. In addition, a large HCC is frequently accompanied by intrahepatic metastases. Presentation of case We describe, the case of a 74-year-old woman with a huge extrahepatically expanding HCC with multiple intrahepatic metastases who was treated by liver resection with repeated transcatheter arterial chemoembolization (TACE). To prevent tumor rupture or bleeding, we performed right hepatectomy. After the operation, TACE was applied for multiple intrahepatic metastases in the remnant liver. Furthermore, the elevated protein induced vitamin K absence (PIVKA II) level had decreased to limits within the normal range. Three months after the first TACE, computed tomography revealed several recurrences in the liver. TACE was applied for the second and third time and the tumors were well controlled. Discussion Although, liver resection is occasionally performed for patients with huge HCC to avoid spontaneous tumor rupture, only surgical approach might not be sufficient for such advanced HCC. To achieve long-term survival, it is necessary to control the residual intrahepatic tumors. We could control multiple intrahepatic metastases with repeated TACEs after hepatectomy. Conclusion Multimodal treatment involving hepatectomy and TACE might be a good treatment strategy for patients with huge HCC with multiple intrahepatic metastases if the tumors are localized in the liver without distant or peritoneal metastasis.

    2013-01-01

    Liver metastases occur in up to 60% of patients with colorectal cancer, and the control of liver metastases is considered to be of primary importance because it is a critical factor in determining prognosis. Radiofrequency ablation (RFA) therapy is one of the least invasive techniques for unresectable hepatic malignancies and can be performed safely using percutaneous, laparoscopic, or open surgical techniques. The local tumor progression rates after RFA for colorectal liver metastases range from 8.8% to 40.0%, and 5-year survival rates range from 20.0% to 48.5%. No prospective, randomized trials comparing the efficacy of RFA with that of surgical resection for colorectal liver metastases are currently available. However, some retrospective studies have reported that patients who received RFA had a survival rate similar to that observed in surgically treated groups, while other studies have reported better survival among patients who underwent surgical resection. The use of a laparoscopic or open surgical approach allows the repeated placement of RFA electrodes at multiple sites to ablate larger tumors. An accurate evaluation of treatment response is very important for the success of RFA therapy because a sufficient safety margin (at least 0.5 cm) can prevent local tumor progression. This review critically summarizes the current status of RFA for liver metastases from colorectal cancer. PMID:23422905

    Merkel cell carcinoma (mcc) is a highly aggressive neuroendocrine tumour of the skin. Remission rates are high with chemotherapy in patients with metastasis, but without any improvement in overall survival. We present the case of a 90-year-old woman with facial mcc. After radiation and surgery, the mcc recurred with widespread cutaneous and regional lymph node metastases. The metastases were treated with weekly intralesional injections of 1-2×10(6) IU interferon alfa-2a, accompanied by topical imiquimod 5% cream 3 times weekly. After partial regression, subcutaneous pegylated interferon alfa-2b was added at a dose of 30 μg weekly, which was then increased to 50 μg weekly. At 4 months after the start of immunotherapy, all cutaneous metastases and the intralesionally treated lymph node metastases receded. Interruption or reduction of systemic interferon application resulted in locoregional relapses that were successfully treated with surgery or intralesional interferon injections. The patient remains alive 30 months after initiation of immunotherapy, suggesting that locally metastasized mcc might be able to be controlled with local and systemic immunotherapy. PMID:27122984

    This study aims to review histological and immunohistochemical features that are useful in the diagnosis of metastases to the breast. Histological features were compared between non‐haematological metastases to the breast and 100 consecutive core biopsy specimens of primary invasive carcinomas of the breast. 18 non‐haematological metastases to the breast were diagnosed over a 10‐year period (0.3% of malignant mammary tumours). Elastosis and carcinoma in situ were seen only in primary mammary cancers. Two‐thirds of tumours had features raising the possibility of metastasis, such as clear cell carcinoma suggestive of renal origin and small cell carcinoma suggestive of pulmonary origin. The features observed in haematological metastases are also described. Immunohistochemical panels to distinguish mammary carcinoma (oestrogen receptor, gross cystic fluid protein‐15) from common metastases to the breast, including carcinoma of the lung (thyroid transcription factor‐1), malignant melanoma (S100, HMB45, melan‐A) and ovarian serous papillary carcinoma (Wilms' tumour 1), are discussed. The pathologist has a key role in considering the diagnosis of metastasis to the breast if the histological features are unusual for a primary mammary tumour. The clinical history is vital in some cases. Immunohistochemistry plays a useful supplementary role. PMID:18042689

    The International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) proposed a new classification for lung adenocarcinoma (AD) based on predominant histologic subtypes, such as lepidic, papillary, acinar, solid, and micropapillary; this system reportedly reflects well outcomes of patients with surgically resected lung AD. However, the prognostic implication of predominant histologic subtypes in lymph nodes metastases is unclear so far. In this study, we compared predominant subtypes between primary lung tumors and lymph node metastatic lesions in 24 patients with surgically treated lung adenocarcinoma with lymph node metastases. Additionally, we analyzed prognostic implications of these predominant histologic subtypes. We observed several discordance patterns between predominant subtypes in primary lung tumors and lymph node metastases. Concordance rates were 22%, 64%, and 100%, respectively, in papillary-, acinar-, and solid-predominant primary lung tumors. We observed that the predominant subtype in the primary lung tumor (HR 12.7, P = 0.037), but not that in lymph node metastases (HR 0.18, P = 0.13), determines outcomes in patients with surgically resected lung AD with lymph node metastases.

    2015-11-01

    An international panel of multidisciplinary experts convened to develop recommendations for managing patients with colorectal cancer (CRC) and synchronous liver metastases (CRCLM). A modified Delphi method was used. CRCLM is defined as liver metastases detected at or before diagnosis of the primary CRC. Early and late metachronous metastases are defined as those detected ⩽12months and >12months after surgery, respectively. To provide information on potential curability, use of high-quality contrast-enhanced computed tomography (CT) before chemotherapy is recommended. Magnetic resonance imaging is increasingly being used preoperatively to aid detection of subcentimetric metastases, and alongside CT in difficult situations. To evaluate operability, radiology should provide information on: nodule size and number, segmental localization and relationship with major vessels, response after neoadjuvant chemotherapy, non-tumoral liver condition and anticipated remnant liver volume. Pathological evaluation should assess response to preoperative chemotherapy for both the primary tumour and metastases, and provide information on the tumour, margin size and micrometastases. Although the treatment strategy depends on the clinical scenario, the consensus was for chemotherapy before surgery in most cases. When the primary CRC is asymptomatic, liver surgery may be performed first (reverse approach). When CRCLM are unresectable, the goal of preoperative chemotherapy is to downsize tumours to allow resection. Hepatic resection should not be denied to patients with stable disease after optimal chemotherapy, provided an adequate liver remnant with inflow and outflow preservation remains. All patients with synchronous CRCLM should be evaluated by a hepatobiliary multidisciplinary team. PMID:26417845

    Bone metastases are a common manifestation of malignancy, and external beam radiotherapy (EBRT) effectively and safely palliates the pain caused by this clinical circumstance. The myriad of EBRT dosing schemes and complexities involved with coordinating radiotherapy with other interventions necessitated the need for bone metastases treatment guidelines. Here we compare and contrast the bone metastases radiotherapy treatment guidelines recently published by the American Society for Radiation Oncology (ASTRO) and the American College of Radiology (ACR). These evaluations acknowledge current controversies in treatment approaches, they evaluate the nuances of ASTRO and ACR task force decision-making regarding standard approaches to care, and they project the upcoming research results that may clarify approaches to palliative radiotherapy for bone metastases. The results of these two dedicated radiotherapy guidelines are compared to the brief mentions of radiotherapy for bone metastases in the National Comprehensive Cancer Network (NCCN) guidelines. Finally, the paper describes how treatment guidelines may influence patterns of care and reimbursement by their use as quality measures by groups such as the National Quality Forum (NQF).

    Effectiveness of stereotactic radiosurgery (SRS) has been shown in patients with one to four brain metastases. Work has been done to evaluate the role of SRS alone treatment without whole-brain radiation therapy in patients with more than four metastases. A recent multiinstitutional JLGK 0901 prospective study revealed the class-2 evidence that SRS without whole-brain radiation therapy is an effective treatment for patients up to 10 metastatic lesions. Several retrospective studies exist to show the efficacy and safety of SRS for patients with even more than 10 lesions. However, patient selection is very critical for SRS alone treatment. The PubMed database was searched using combinations of search terms and synonyms for multiple brain metastases, Gamma Knife and SRS published between January 1, 2005 and January 1, 2015 in order to address the effectiveness of Gamma Knife for patients with multiple brain metastases. Good performance status, controlled primary disease, total treated tumor volume of 15 cm(3) or less have been found to be significant predictors for survival among patients with two or more brain lesions. The data suggest that SRS can be used and whole brain radiation therapy can be withheld in selected patients with multiple lesions to avoid acute or chronic adverse effects, especially neurocognitive decline, without causing survival disadvantage. In this review, we assessed the evidence for SRS treatment of patients with multiple brain metastases. PMID:26811300

    Between 1984 and 2002, pulmonary metastases were detected in 42 (4%) out of 1,023 patients with differentiated thyroid carcinoma (DTC) in our department. The age at diagnosis ranged from 6 to 77 years. Lung metastases were diagnosed by both increased thyroglobulin (Tg) levels and positive uptake of iodine-131 on scans, and/or positive radiological findings. The primary tumours were histologically classified as papillary (30 patients), follicular (nine patients) and poorly differentiated (two tall cell, one insular carcinoma). The duration of follow-up ranged from 24 to 228 months. The end-results of the (131)I therapy were evaluated. The treatment of choice was (131)I therapy of metastases after total thyroidectomy plus lymph node dissection (if lymph node metastases were present). Applied single and total (131)I activities were 1.8-10.4 GBq and 5.5-43.7 GBq, respectively. Lung metastases were present at the time of diagnosis in 30 patients and developed during the follow-up period in the remaining 12. Twelve patients with extensive metastases died of thyroid carcinoma and another died due to secondary malignancy (malignant mesothelioma). Ten patients with lung metastases remain completely free of disease and are probably cured, while another seven were stable at the time of study. Three- and five-year survival rates were 86% (36/42) and 76% (32/42), respectively. To define the diagnostic value of high-resolution computed tomography (HRCT) and identify the distinctive features of lung metastases from DTC, 22 patients were further examined with HRCT within 2 weeks of the initial diagnosis of lung metastases and the results were compared with chest X-ray findings. HRCT detected metastases in 10 out of 14 patients with a normal chest X-ray and confirmed metastases in all patients with positive (n=5) and suspicious (n=3) chest X-ray. HRCT did not show any abnormalities in four patients with positive lung uptake on (131)I whole-body images. Stage of disease, existence

    2011-01-01

    Introduction Activation status of the phosphatidylinositol 3-kinase (PI3K) pathway in breast cancer brain metastases (BCBMs) is largely unknown. We examined expression of phospho(p)-AKT, p-S6, and phosphatase and tensin homologue (PTEN) in BCBMs and their implications for overall survival (OS) and survival after BCBMs. Secondary analyses included PI3K pathway activation status and associations with time to distant recurrence (TTDR) and time to BCBMs. Similar analyses were also conducted among the subset of patients with triple-negative BCBMs. Methods p-AKT, p-S6, and PTEN expression was assessed with immunohistochemistry in 52 BCBMs and 12 matched primary BCs. Subtypes were defined as hormone receptor (HR)+/HER2-, HER2+, and triple-negative (TNBC). Survival analyses were performed by using a Cox model, and survival curves were estimated with the Kaplan-Meier method. Results Expression of p-AKT and p-S6 and lack of PTEN (PTEN-) was observed in 75%, 69%, and 25% of BCBMs. Concordance between primary BCs and matched BCBMs was 67% for p-AKT, 58% for p-S6, and 83% for PTEN. PTEN- was more common in TNBC compared with HR+/HER2- and HER2+. Expression of p-AKT, p-S6, and PTEN- was not associated with OS or survival after BCBMs (all, P > 0.06). Interestingly, among all patients, PTEN- correlated with shorter time to distant and brain recurrence. Among patients with TNBC, PTEN- in BCBMs was associated with poorer overall survival. Conclusions The PI3K pathway is active in most BCBMs regardless of subtype. Inhibition of this pathway represents a promising therapeutic strategy for patients with BCBMs, a group of patients with poor prognosis and limited systemic therapeutic options. Although expression of the PI3K pathway did not correlate with OS and survival after BCBM, PTEN- association with time to recurrence and OS (among patients with TNBC) is worthy of further study.

    Abstract The response rate of patients with unresectable liver-limited metastases of colorectal cancer can be improved by converting inoperable disease to operable disease. However, the benefits of conversion chemotherapy for survival are still controversial. Patients considered to have technically inoperable disease by a multidisciplinary team were retrospectively analyzed. Patients were stratified based on the treatment they received, into the chemotherapy only (G1), chemotherapy plus bevacizumab (G2), or chemotherapy plus cetuximab (G3) groups. The primary endpoint was the resection rate. The secondary endpoint was the overall survival (OS), according to both the treatment received and liver surgery status. In total, 104 patients were included: 30 in the G1, 39 in the G2, and 35 in the G3 groups. All G3 patients had the wild-type KRAS exon 2. The surgical resection rates for patients in the G1, G2, and G3 groups were 43.3% (13/30), 30.7% (12/39), and 51.4% (18/35), respectively. Disease-free survival did not show significant differences among the 3 groups. The median OS was 35.2 months in the G1, 28.8 months in the G2, and 42.1 months in the G3 (P = 0.25) groups. The OS was significantly higher in patients who underwent surgical resection than those who did not. The median OS was 28.4 months in patients who did not undergo resection, whereas it had not been reached after a median follow-up period of 37.5 months for patients who underwent surgical resection (events: 21/43). Our data confirmed that the conversion of initially inoperable disease to operable disease conferred a survival benefit, even in patients who relapsed after surgery. The addition of cetuximab to chemotherapy improved the objective response and resection rates, conferring a potential survival benefit even in patients whose diseases were not converted to operable disease, compared to chemotherapy alone or in combination with bevacizumab.

    Pseudo-Meigs’ syndrome associated with colorectal cancer is extremely rare. We report here a case of pseudo-Meigs’ syndrome secondary to metachronous ovarian metastases from colon cancer. A 65-year-old female with a history of surgery for transverse colon cancer and peritoneal dissemination suffered from metachronous ovarian metastases during treatment with systemic chemotherapy. At first, neither ascites nor pleural effusion was observed, but she later complained of progressive abdominal distention and dyspnea caused by rapidly increasing ascites and pleural effusion and rapidly enlarging ovarian metastases. Abdominocenteses were repeated, and cytological examinations of the fluids were all negative for malignant cells. We suspected pseudo-Meigs’ syndrome, and bilateral oophorectomies were performed after thorough informed consent. The patient’s postoperative condition improved rapidly after surgery. We conclude that pseudo-Meigs’ syndrome should be included in the differential diagnosis of massive or rapidly increasing ascites and pleural effusion associated with large or rapidly enlarging ovarian tumors.

    Metastases of solid tumors to the pituitary gland are often asymptomatic or appereas as with diabetes insipid us. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The presentation with an acute adrenal insufficiency is a rare event. A 69-year-old men presented with vomiting, low blood pressure and hypoglycemia. Hormonal exploration confirmed a hypopituitarism. Appropriate therapy was initiated urgently. The hypothalamic-pituitary MRI showed a pituitary hypertrophy, a nodular thickening of the pituitary stalk. The chest X Rays revealed pulmonary opacity. Computed tomography scan of the chest showed a multiples tumors with mediastinal lymphadenopathy. Bronchoscopy and biopsy demonstrated a pulmonary adenocarcinoma. Hence we concluded to a lung cancer with multiple pituitary and adrenal gland metastases. This case emphasizes the need for an etiological investigation of acute adrenal insufficiency after treatment of acute phase. PMID:27200139

    We report a case of regression of multiple pulmonary metastases, which originated from hepatocellular carcinoma after treatment with intravenous administration of high-dose vitamin C. A 74-year-old woman presented to the clinic for her cancer-related symptoms such as general weakness and anorexia. After undergoing initial transarterial chemoembolization (TACE), local recurrence with multiple pulmonary metastases was found. She refused further conventional therapy, including sorafenib tosylate (Nexavar). She did receive high doses of vitamin C (70 g), which were administered into a peripheral vein twice a week for 10 months, and multiple pulmonary metastases were observed to have completely regressed. She then underwent subsequent TACE, resulting in remission of her primary hepatocellular carcinoma. PMID:26256994

    Purpose: To investigate the efficacy of palliative radiotherapy (RT) in relieving metastatic bone pain in elderly patients. Methods and Materials: The response to RT for palliation of metastatic bone pain was evaluated from a prospective database of 558 patients between 1999 and 2008. The pain scores and analgesic intake were used to calculate the response according to the International Bone Metastases Consensus Working Party palliative RT endpoints. Subgroup analyses for age and other demographic information were performed. Results: No significant difference was found in the response rate in patients aged >=65, >=70, and >=75 years compared with younger patients at 1, 2, or 3 months after RT. The response was found to be significantly related to the performance status. Conclusion: Age alone did not affect the response to palliative RT for bone metastases. Elderly patients should be referred for palliative RT for their painful bone metastases, regardless of age, because they receive equal benefit from the treatment.

    Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases. PMID:26839672

    We report two cases of spontaneous regression of multiple pulmonary metastases occurring after radiofrequency ablation (RFA) of a single lung metastasis. To the best of our knowledge, these are the first such cases reported. These two patients presented with lung metastases progressive despite treatment with interleukin-2, interferon, or sorafenib but were safely ablated with percutaneous RFA under computed tomography guidance. Percutaneous RFA allowed control of the targeted tumors for >1 year. Distant lung metastases presented an objective response despite the fact that they received no targeted local treatment. Local ablative techniques, such as RFA, induce the release of tumor-degradation product, which is probably responsible for an immunologic reaction that is able to produce a response in distant tumors.

    Pseudo-Meigs' syndrome associated with colorectal cancer is extremely rare. We report here a case of pseudo-Meigs' syndrome secondary to metachronous ovarian metastases from colon cancer. A 65-year-old female with a history of surgery for transverse colon cancer and peritoneal dissemination suffered from metachronous ovarian metastases during treatment with systemic chemotherapy. At first, neither ascites nor pleural effusion was observed, but she later complained of progressive abdominal distention and dyspnea caused by rapidly increasing ascites and pleural effusion and rapidly enlarging ovarian metastases. Abdominocenteses were repeated, and cytological examinations of the fluids were all negative for malignant cells. We suspected pseudo-Meigs' syndrome, and bilateral oophorectomies were performed after thorough informed consent. The patient's postoperative condition improved rapidly after surgery. We conclude that pseudo-Meigs' syndrome should be included in the differential diagnosis of massive or rapidly increasing ascites and pleural effusion associated with large or rapidly enlarging ovarian tumors.

    Pleomorphic salivary adenomas (PAs) are the commonest benign tumours of glandular origin in the head and neck. Occasionally PAs undergo malignant transformation to carcinoma-ex-PA and can metastasise. More rarely they metastasise without malignant transformation of the primary tumour. We present a case of a benign pleomorphic salivary gland adenoma, presenting 7 years later with multiple liver metastases and a synchronous pulmonary metastasis. Histological analysis of the lung and liver lesions confirmed a diagnosis of metastasising pleomorphic adenoma (MPA). The lung lesion was fully excised, but the multifocal nature of the liver lesions rendered them inoperable. The patient is being managed conservatively and to date has no local recurrence of the primary salivary gland tumour or any further metastases. To the best of our knowledge this is the first case of MPA with simultaneous metastasis to both lungs and liver, and also the first to describe multiple liver metastases. PMID:24907217

    The incidence of brain metastases from breast cancer is increasing with diagnosis and therapeutics progress, especially with systemic therapies. The occurrence of multiple brain metastases remains a delicate situation when surgery and stereotactic radiosurgery are not indicated, nor available. Treatment strategy is based on the patient's general condition and extracranial disease status. Whole brain radiation therapy remains the gold standard local treatment but its efficacy is limited with a median overall survival of 6 months. New strategies are needed for increasing survival and patients' quality of life. Combining radiation therapy and chemotherapy has been a subject of interest. This article sums up the different radiotherapy plus concomitant systemic therapies combinations for the treatment of brain metastases from breast cancer. PMID:24731405

  20. Multi-technique imaging of bone metastases: spotlight on PET-CT.

    2016-07-01

    There is growing evidence that molecular imaging of bone metastases with positron-emission tomography (PET) can improve diagnosis and treatment response assessment over current conventional standard imaging methods, although cost-effectiveness has not been assessed. In most cancer types, 2-[(18)F]-fluoro-2-deoxy-d-glucose ((18)F-FDG)-PET is an accurate method for detecting bone metastases. For example, in breast cancer, combined (18)F-FDG-PET and computed tomography (CT) is more sensitive at detecting bone metastases than (99m)technetium (Tc)-labelled diphosphonate planar bone scintigraphy (BS) and there is increasing evidence to support the use of serial (18)F-FDG-PET for the assessment of osseous response to treatment. Preliminary data suggest improved diagnostic accuracy of (18)F-FDG-PET-CT in a number of other malignancies including lung, thyroid, head and neck, gastro-oesophageal cancers, and osteosarcoma. As a bone-specific tracer, there is accumulating evidence to support the use of sodium (18)F-fluoride ((18)F-NaF) PET-CT in the diagnosis of skeletal metastases in breast and prostate cancer, although relatively little data are available to support its use for assessment of treatment response. In prostate cancer, (11)C-choline and (18)F-choline PET-CT have better specificities than (18)F-NaF-PET-CT, but equivalent sensitivities in the detection of bone metastases. We review the current literature for staging and response assessment of bone metastases in different cancers. PMID:26997430

    Purpose: Stereotactic radiosurgery (SRS) for brain metastases is a relatively well-studied technology with established guidelines regarding patient selection, although its implementation is technically complex. We evaluated the extent to which local availability of SRS affected the treatment of patients with brain metastases. Methods and Materials: We identified 3030 patients who received whole-brain radiation therapy (WBRT) for brain metastases in 1 of 7 cancer centers in Ontario. Clinical data were abstracted for a random sample of 973 patients. Logistic regression analyses were performed to identify factors associated with the use of SRS as a boost within 4 months following WBRT or at any time following WBRT. Results: Of 898 patients eligible for analysis, SRS was provided to 70 (7.8%) patients at some time during the course of their disease and to 34 (3.8%) patients as a boost following WBRT. In multivariable analyses, factors significantly associated with the use of SRS boost following WBRT were fewer brain metastases (odds ratio [OR] = 6.50), controlled extracranial disease (OR = 3.49), age (OR = 0.97 per year of advancing age), and the presence of an on-site SRS program at the hospital where WBRT was given (OR = 12.34; all P values were <.05). Similarly, availability of on-site SRS was the factor most predictive of the use of SRS at any time following WBRT (OR = 5.98). Among patients with 1-3 brain metastases, good/fair performance status, and no evidence of active extracranial disease, SRS was provided to 40.3% of patients who received WBRT in a hospital that had an on-site SRS program vs 3.0% of patients who received WBRT at a hospital without SRS (P<.01). Conclusions: The availability of on-site SRS is the factor most strongly associated with the provision of this treatment to patients with brain metastases and appears to be more influential than accepted clinical eligibility factors.

    Purpose: With the advent of intensity-modulated radiotherapy, the ability to limit the radiation dose to normal tissue offers an avenue to limit side effects. This study attempted to delineate the distribution of brain metastases with relation to the hippocampus for the purpose of exploring the viability of tomotherapy-guided hippocampal sparing therapy potentially to reduce neurocognitive deficits from radiation. Methods and Materials: The pre-radiotherapy T1-weighted, postcontrast axial MR images of 100 patients who received whole brain radiotherapy, stereotactic radiosurgery, or a radiosurgical boost following whole brain radiotherapy between 2002 and 2006 were examined. We contoured brain metastases as well as hippocampi with 5-, 10-, and 15-mm expansion envelopes. Results: Of the 272 identified metastases, 3.3% (n = 9) were within 5 mm of the hippocampus, and 86.4% of metastases were greater than 15 mm from the hippocampus (n = 235). The most common location for metastatic disease was the frontal lobe (31.6%, n = 86). This was followed by the cerebellum (24.3%, n = 66), parietal lobe (16.9%, n = 46), temporal lobe (12.9%, n = 35), occipital lobe (7.7%, n = 21), deep brain nuclei (4.0%, n = 11), and brainstem (2.6%, n = 7). Conclusions: Of the 100 patients, 8 had metastases within 5 mm of the hippocampus. Hence, a 5-mm margin around the hippocampus for conformal avoidance whole brain radiotherapy represents an acceptable risk, especially because these patients in the absence of any other intracranial disease could be salvaged using stereotactic radiosurgery. Moreover, we developed a hippocampal sparing tomotherapy plan as proof of principle to verify the feasibility of this therapy in the setting of brain metastases.

    It is often addressed that the most appropriate candidate, theoretically, for radioimmunotherapy (RIT) is not bulky tumor burden but for micro or occult metastatic foci, The major obstacles in the verification for veracious efficacy of RIT had been clinically and preclinically the difficulty in obtaining such a model. We have developed the model of testicular tumor (primary site) with visible small metastases to the lymph nodes (LNs) and non-visible (occult) lesions to distant organs in severe combined immunodeficient (SCID) mice. And thus, the suppression of minute tumor depositions after RIT was evaluated. One week after hemilateral intratesticular injection of 2 million of HELA Hep 2 cells that expressed placental alkaline phosphatase (PLAP), the group of the mice were treated with a single dose of I-131 labeled HPMS-1, anti-PLAP MoAb or with saline control. The I-131 labeled HPMS-1 (5.6 MBq / 150 {mu}g) was intravenously administered and at 2 weeks after, the testis, retroperitoneal and intraperitoneal LNs and other gans were removed. For the control group, the testicular tumor and LNs metastases were found in 100% and 86% of the mice. The metastases in the liver and lung were not observed by histological examination but in all mouse samples, the PCR (polymerase chain reaction) assay could identify the human {beta}-globin gene derived from HeLa cells, indicating the presence of definitive metastases. For the treated group, the average testicular tumor weight was significantly reduced by the factor of 2.4 (132 mg vs 311 mg, p<0.01). The LNs metastases were even more distinctively suppressed by the factor of 45.7 (13 mg vs 599 mg, p,0.05). Remarkably, the PCR products from the occult metastases were almost completely controlled; 97% suppression found for the liver and 81% for the lung. Thus, we conclude that using I-131 as a label, RIT is justified to used for targeting and killing minute tumor foci.

    Purpose: To present guidance for patients and physicians regarding the use of radiotherapy in the treatment of bone metastases according to current published evidence and complemented by expert opinion. Methods and Materials: A systematic search of the National Library of Medicine's PubMed database between 1998 and 2009 yielded 4,287 candidate original research articles potentially applicable to radiotherapy for bone metastases. A Task Force composed of all authors synthesized the published evidence and reached a consensus regarding the recommendations contained herein. Results: The Task Force concluded that external beam radiotherapy continues to be the mainstay for the treatment of pain and/or prevention of the morbidity caused by bone metastases. Various fractionation schedules can provide significant palliation of symptoms and/or prevent the morbidity of bone metastases. The evidence for the safety and efficacy of repeat treatment to previously irradiated areas of peripheral bone metastases for pain was derived from both prospective studies and retrospective data, and it can be safe and effective. The use of stereotactic body radiotherapy holds theoretical promise in the treatment of new or recurrent spine lesions, although the Task Force recommended that its use be limited to highly selected patients and preferably within a prospective trial. Surgical decompression and postoperative radiotherapy is recommended for spinal cord compression or spinal instability in highly selected patients with sufficient performance status and life expectancy. The use of bisphosphonates, radionuclides, vertebroplasty, and kyphoplasty for the treatment or prevention of cancer-related symptoms does not obviate the need for external beam radiotherapy in appropriate patients. Conclusions: Radiotherapy is a successful and time efficient method by which to palliate pain and/or prevent the morbidity of bone metastases. This Guideline reviews the available data to define its proper use

    Purpose: The prognosis of hepatocellular carcinoma (HCC) patients with extrahepatic metastases is extremely poor. Helical tomotherapy, an image-guided, intensity-modulated radiotherapy system, can allow for simultaneous and precise targeting of multiple cancerous lesions, while sparing normal tissues. This study evaluated the feasibility and outcome of tomotherapy for advanced HCC with metastases. Patients and Methods: A total of 42 consecutive HCC patients with metastases were treated with tomotherapy using the Hi-Art system. A total of 152 intra- and extrahepatic lesions (3.5 lesions/patient) were treated simultaneously, with a dose of 51.03 Gy (range, 30-57.61) in 10 fractions. Transarterial chemolipiodolization using epirubicin (50 mg) and cisplatin (60 mg) was repeated in patients with intrahepatic HCC (mean size, 9.0 cm) after tomotherapy. Results: An objective response (complete response and partial response) was achieved in 45.2% of patients with intrahepatic tumors, 68.4% of patients with pulmonary lesions, 60.0% of patients with lymph node/adrenal lesions, and 66.7% of patients with soft-tissue metastases. The complete response rate for those with pulmonary and lymph node/adrenal metastases was 26.3% and 5.0%, respectively. The overall survival rate at 1 and 2 years was 50.1% and 14.9%, respectively, with a median survival of 12.3 months. The actuarial in-field tumor control rate for {<=}1 year was 79.0%. No cases of Grade 4-5 acute toxicity occurred. Conclusion: The results of this study have shown that helical tomotherapy is safe and feasible without major toxicities for the treatment of advanced HCC and results in excellent tumor control and a potential survival benefit. This approach is expected to be a useful palliative option for selected HCC patients with metastases.

    Purpose: Many patients with brain metastases receive whole-brain radiotherapy (WBRT) alone. Using 10 Multiplication-Sign 3 Gy in 2 weeks is the standard regimen in most centers. Regarding the extraordinarily poor survival prognosis of elderly patients with multiple brain metastases, a shorter WBRT regimen would be preferable. This study compared 10 Multiplication-Sign 3 Gy with 5 Multiplication-Sign 4 Gy in elderly patients ({>=}65 years). Methods and Materials: Data from 455 elderly patients who received WBRT alone for brain metastases were retrospectively analyzed. Survival and local (= intracerebral) control of 293 patients receiving 10 Multiplication-Sign 3 Gy were compared with 162 patients receiving 5 Multiplication-Sign 4 Gy. Eight additional potential prognostic factors were investigated including age, gender, Karnofsky performance score (KPS), primary tumor, number of brain metastases, interval from tumor diagnosis to WBRT, extracerebral metastases, and recursive partitioning analysis (RPA) class. Results: The 6-month overall survival rates were 29% after 5 Multiplication-Sign 4 Gy and 21% after 10 Multiplication-Sign 3 Gy (p = 0.020). The 6-month local control rates were 12% and 10%, respectively (p = 0.32). On multivariate analysis, improved overall survival was associated with KPS {>=} 70 (p < 0.001), only one to three brain metastases (p = 0.029), no extracerebral metastasis (p = 0.012), and lower RPA class (p < 0.001). Improved local control was associated with KPS {>=} 70 (p < 0.001), breast cancer (p = 0.029), and lower RPA class (p < 0.001). Conclusions: Shorter-course WBRT with 5 Multiplication-Sign 4 Gy was not inferior to 10 Multiplication-Sign 3 Gy with respect to overall survival or local control in elderly patients. 5 Multiplication-Sign 4 Gy appears preferable for the majority of these patients.

    AIM: To describe the multidetector computed tomography features of pancreatic metastasis from leiomyosarcoma (LMS). METHODS: Between January 1995 and December 2012, 13 consecutive patients (11 women, 2 men; mean age of 57 years; range, 38-78 years) with pancreatic metastases from LMS were included in our study. Imaging features including location, number, largest dimension, tumor attenuation and enhancement characteristics, presence of necrosis, pancreatic ductal dilatation, common bile duct (CBD) dilatation, presence of pancreatitis, and atrophy were documented. RESULTS: The most common site of origin of the pancreatic metastases from LMS was uterus (38.5%), followed by retroperitoneum (30.8%) and extremity (23.1%). None of the patients in our study had pancreas as the first site of metastasis. All patients developed pancreatic metastases at a median interval of 24 mo. Pancreatic metastases from LMS were solitary in 8/13 patients and multiple in 5/13 patients, had no predilection for any part of the pancreas, were hypovascular on arterial phase in 10/13 patients and associated with pancreatic duct dilatation in 3/13 patients. None had CBD dilatation. None of the pancreatic metastases in LMS cohort caused pancreatitis, and atrophy. Median duration of follow-up was 19 mo for LMS cohort during which two patients underwent resection of metastasis (median survival 45 mo) while the remaining underwent systemic therapy (median survival 13 mo). CONCLUSION: Pancreatic metastases from LMS are often solitary and hypovascular masses and less commonly associated with pancreatic ductal dilatation, CBD dilatation, pancreatitis or pancreatic atrophy. Surgical resection of solitary LMS pancreatic metastasis can be considered due to the long survival of these patients. PMID:27027985

    The metastasis of malignant tumors to the lung is relatively common; however, cavitation of metastases is extremely rare in clinical cases, and the various mechanisms are controversial. The majority of irregular metastatic cavities form naturally and are detected incidentally when patients are examined prior to any therapeutic measures. The current study presents the case of a lung adenocarcinoma patient with total cavitation of intrapulmonary metastases following effective targeted therapy at the First Affiliated Hospital of Nanjing Medical University. The morphological changes were followed up for three years. This patient presented thin-walled and smooth clean cavities, which provides an indication of the effectiveness of treatment.

    Lymph node metastasis is a strong predictor of poor outcome in cancer patients. Animal studies of lymph node metastasis are constrained by difficulties in the establishment of appropriate animal models, limitations in the noninvasive monitoring of lymph node metastasis progression, and challenges in the pathologic confirmation of lymph node metastases. In this comprehensive review, we summarize available preclinical animal cancer models for noninvasive imaging and identification of lymph node metastases of non-hematogenous cancers. Furthermore, we discuss the strengths and weaknesses of common noninvasive imaging modalities used to identify tumor-bearing lymph nodes and provide guidelines for their pathological confirmation.

    The adrenal metastasis from differentiated thyroid carcinoma is uncommon. Metastatic involvement of both adrenal and brain in the same patient from differentiated thyroid carcinoma is rare. Here, we described an unusual case with iodine-avid lung, bone, adrenal, liver, and brain metastases from follicular thyroid carcinoma confirmed by 131I SPECT/CT. The utilization of SPECT/CT in thyroid cancer patients can detect the presence of metastases and also exclude potential false-positive lesions. Our case demonstrates that SPECT/CT is helpful in localizing and confirming metastatic lesions from differentiated thyroid carcinoma in rare and unusual sites. PMID:26018699

    Accurate lymph node analysis is essential to determine the prognosis and treatment of patients suffering from melanoma. The initial results of a tomographic photoacoustic modality to detect melanoma metastases in resected lymph nodes are presented based on phantom models and a human lymph node. The results show melanoma metastases detection is feasible and the setup is capable of distinguishing absorbing structures down to 1 mm. In addition, the use of longer laser wavelengths could result in an image containing a higher contrast ratio. Future research shall be focused on using the melanin characteristics to improve contrast and detection possibilities.

    Five patients underwent preoperative embolization of osseous metastases from renal cell carcinoma. The group consisted of four men and one woman who ranged in age from 46 to 79 years. The lesions were located in the pubic ramus and acetabulum, proximal femur, femoral midshaft, proximal humerus, and proximal tibia. All embolizations were performed within 24 hours of surgery. The internal fixation and tumor curettage was accomplished with estimated perioperative blood loss ranging from 10 ml to 1,250 ml. All patients had significant restoration of function following surgery. The authors suggest that preoperative embolization is an important and efficacious adjunct in the management of hypervascular renal cell osseous metastases.

    Patients with recurrences from pancreas adenocarcinoma have a poor survival rate despite new chemotherapy treatment options. Recurrences are mainly hepatic metastases or peritoneal dissemination and surgical treatment is not recommended. Late and single metachronous pulmonary recurrences are uncommon and may mimic primary lung carcinoma. We report two patients with late and unique pulmonary metastasis from pancreatic cancer. These two patients underwent surgical resection; three and five years later, they did not experience recurrences. Cases called for a surgical approach in late and unique pulmonary metastases from pancreatic cancer, and paved the way for a prolonged chemotherapy free period. PMID:26461032

    Patients with non-resectable metastases of various diseases are today treated by one of several different techniques, such as radiofrequency ablation, laser-induced thermoablation or stereotactic radiotherapy. Frequently, the employment of these therapeutic strategies is limited due to their invasiveness and treatment-associated morbidity. Furthermore, stereotactic radiotherapy is associated with a high degree of patient discomfort due to the necessary fixation of moving inner organs (lung, liver). With the development of the cyberknife radiosurgery technique, an image-guided, superselective, robot-based radiotherapy, these problems seem to be resolved. With this technique, metastases may be treated in an outpatient single-treatment setting. PMID:20340074

    Hepatic metastases rather than the primary neoplasm usually dictate the course of the disease and patient's survival. For unresectable disease, intraarterial infusion of chemotherapy, embolization, and chemoembolization are viable alternatives. Intraarterial therapy for hepatic metastases is based on the dual blood supply of the normal liver (portal vein, 75%, and hepatic artery, 25%) and that of the tumors (hepatic artery, 90%). Intraarterial infusion delivers a higher concentration of chemotherapy, whereas chemoembolization adds ischemia and increased contact time with the tumor. Selective vascular occlusion for infusion, redistribution of the blood supply and pulsatile flow enhance the delivery of therapeutic agents to the liver. PMID:2121343

    The development of liver metastases is a common clinical entity in the clinical course of colorectal cancer. For patients with isolated liver involvement, surgical resection is the only treatment that can provide a chance of prolonged survival and cure. However, most of these patients are not initially eligible for the surgery. Selected patients with initially considered to have unresectable disease may become resectable after systemic (chemotherapy ± biological therapy) and loco-regional treatment modalities including hepatic arterial infusion.

    Breast cancer is the most common malignancy among women and is a significant cause of morbidity and mortality worldwide. With the advent of improved imaging techniques and screening programmes, only a small proportion of women present with metastatic disease. Metastases involving the gastrointestinal (GI) tract and orbit are rare occurrences. We describe the case of a woman with simultaneous GI and orbital metastases from breast cancer who initially presented with abdominal pain and blurred vision and also summarise a review of the literature.

    Cutaneous metastasis from visceral tumors is a rare entity with a reported incidence between 0.3% and 9.8%. These usually occur late in the course of the disease; the average time interval between the diagnosis of malignancy and presentation of cutaneous metastases has been reported to be 33 months. In rare instances (in about 0.8%–1.3% of patients), cutaneous metastases may be a pointer to an underlying undiagnosed malignancy. We report two patients presenting to us with soft, nodular, cutaneous lesions, which was the manifestation of metastatic signet cell carcinoma arising from the gut. We report these cases owing to their rarity.

    The development of liver metastases is a common clinical entity in the clinical course of colorectal cancer. For patients with isolated liver involvement, surgical resection is the only treatment that can provide a chance of prolonged survival and cure. However, most of these patients are not initially eligible for the surgery. Selected patients with initially considered to have unresectable disease may become resectable after systemic (chemotherapy ± biological therapy) and loco-regional treatment modalities including hepatic arterial infusion. Patients who have colorectal liver metastases ideally should be referred to a multidisciplinary cancer care team in order to identify the most optimal management approach. PMID:26862487

    An 84-year-old woman was diagnosed with malignant melanoma after resection of a nasal cavity tumor in February 2008. In April 2010, she underwent small bowel resection because of ileus due to small intestinal metastases. She was diagnosed with ileus again in October 2010. Computed tomography (CT) and 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) revealed invagination of the small intestine and small intestinal metastases. We performed a palliative small bowel resection. She had a good postoperative course and was discharged 2 weeks after surgery. Oral intake was possible for 6 months until her death. PMID:26805140

    Neck dissection is an important treatment for metastases from upper aerodigestive carcinoma; an event that markedly reduces survival. Since its inception, the philosophy of the procedure has undergone significant change from one of radicalism to the current conservative approach. Furthermore, nonsurgical modalities have been introduced, and, in many situations, have supplanted neck surgery. The refinements of imaging the neck based on the concept of neck level involvement has encouraged new philosophies to evolve that seem to benefit patient outcomes particularly as this relates to diminished morbidity. The purpose of this review was to highlight the new paradigms for surgical removal of neck metastases using an evidence-based approach. PMID:24623715

    The objective of this study was to characterize and differentiate vascular patterns of choroidal melanomas and choroidal metastases by color flow mapping (CFM). We conducted a retrospective chart study on CFM findings in 18 patients with choroidal melanomas and 10 patients with choroidal metastases. We evaluated the possibilities of applying CFM to identify hypo- versus hyper-vascularity within the tumor, a central 'dominant vessel', and Doppler signals in the tumor's center and/or periphery. CFM demonstrated hypervascular patterns in 33% melanomas and 100% metastases (p<0.0001). CFM identified a central dominant vessel in 94% melanomas and 0/10 metastases (p<0.0001). Vascularity occupied the center of 11/18 melanomas and 0/10 metastases (p<0.0001), the periphery of 2/18 melanomas and 9/10 metastases (p<0.0001), and equally occupied the tumor's center and periphery of 5/18 melanomas and 1/10 metastases (p<0.0001). Based on our findings, we conclude that CFM was capable of non-invasively demonstrating different and distinct vascular patterns in malignant choroidal melanomas and choroidal metastases.

    Purpose We evaluated the feasibility, reliability, and validity of the Brain Metastases Symptom Checklist (bmsc), a novel self-report measure of common symptoms experienced by patients with brain metastases. Methods Patients with first-presentation symptomatic brain metastases (n = 137) referred for whole-brain radiotherapy (wbrt) completed the bmsc at time points before and after treatment. Their caregivers (n = 48) provided proxy ratings twice on the day of consultation to assess reliability, and at week 4 after wbrt to assess responsiveness to change. Correlations with 4 other validated assessment tools were evaluated. Results The symptoms reported on the bmsc were largely mild to moderate, with tiredness (71%) and difficulties with balance (61%) reported most commonly at baseline. Test–retest reliability for individual symptoms had a median intraclass correlation of 0.59 (range: 0.23–0.85). Caregiver proxy and patient responses had a median intraclass correlation of 0.52. Correlation of absolute scores on the bmsc and other symptom assessment tools was low, but consistency in the direction of symptom change was observed. At week 4, change in symptoms was variable, with improvements in weight gain and sleep of 42% and 41% respectively, and worsening of tiredness and drowsiness of 62% and 59% respectively. Conclusions The bmsc captures a wide range of symptoms experienced by patients with brain metastases, and it is sensitive to change. It demonstrated adequate test–retest reliability and face validity in terms of its responsiveness to change. Future research is needed to determine whether modifications to the bmsc itself or correlation with more symptom-specific measures will enhance validity. PMID:27330360

    Formation of metastases from various tumor entities in the brain is a major problem for the treatment of advanced cancer. We describe target molecules and tools for the delivery of small molecules or proteins across the blood-brain barrier (BBB), and the treatment of brain tumors and metastases with antibody-related moieties. In addition, drugs preventing formation of metastases or interfering with the growth of established metastases are described, as well as pre-clinical metastasis models and corresponding clinical data. Furthermore, we discuss the delivery of effector proteins and antibody-based moieties fused with an antibody-based scaffold across the BBB in several model systems which might be applicable for the treatment of brain metastases.

    Breast cancer is the second most common cause of brain metastases and deserves particular attention in relation to current prolonged survival of patients with metastatic disease. Advances in both systemic therapies and brain local treatments (surgery and stereotactic radiosurgery) have led to a reappraisal of brain metastases management. With respect to this, the literature review presented here was conducted in an attempt to collect medical evidence-based data on the use of whole-brain radiotherapy for the treatment of brain metastases from breast cancer. In addition, this study discusses here the potential differences in outcomes between patients with brain metastases from breast cancer and those with brain metastases from other primary malignancies and the potential implications within a treatment strategy.

    Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT)/calcium folinate (leucovorin, LV) was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX) were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

    Purpose: To update the international consensus on palliative radiotherapy endpoints for future clinical trials in bone metastases by surveying international experts regarding previous uncertainties within the 2002 consensus, changes that may be necessary based on practice pattern changes and research findings since that time. Methods and Materials: A two-phase survey was used to determine revisions and new additions to the 2002 consensus. A total of 49 experts from the American Society for Radiation Oncology, the European Society for Therapeutic Radiology and Oncology, the Faculty of Radiation Oncology of the Royal Australian and New Zealand College of Radiologists, and the Canadian Association of Radiation Oncology who are directly involved in the care of patients with bone metastases participated in this survey. Results: Consensus was established in areas involving response definitions, eligibility criteria for future trials, reirradiation, changes in systemic therapy, radiation techniques, parameters at follow-up, and timing of assessments. Conclusion: An outline for trials in bone metastases was updated based on survey and consensus. Investigators leading trials in bone metastases are encouraged to adopt the revised guideline to promote consistent reporting. Areas for future research were identified. It is intended for the consensus to be re-examined in the future on a regular basis.

    Purpose To investigate the outcomes of patients with spinal metastases from hepatocellular carcinoma (HCC), who were treated by stereotactic body radiotherapy (SBRT). Materials and Methods This retrospective study evaluated 23 patients who underwent SBRT from October 2008 to August 2012 for 36 spinal metastases from HCC. SBRT consisted of approximately 2 fractionation schedules, which were 18 to 40 Gy in 1 to 4 fractions for group A lesions (n = 15) and 50 Gy in 10 fractions for group B lesions (n = 21). Results The median follow-up period was 7 months (range, 2 to 16 months). Seven patients developed grade 1 or 2 gastrointestinal toxicity, and one developed grade 2 leucopenia. Compression fractures occurred in association with 25% of the lesions, with a median time to fracture of 2 months. Pain relief occurred in 92.3% and 68.4% of group A and B lesions, respectively. Radiologic response (complete and partial response) occurred in 80.0% and 61.9% of group A and B lesions, respectively. The estimated 1-year spinal-tumor progression-free survival rate was 78.5%. The median overall survival period and 1-year overall survival rate were 9 months (range, 2 to 16 months) and 25.7%, respectively. Conclusion SBRT for spinal metastases from HCC is well tolerated and effective at providing pain relief and radiologic response. Because compression fractures develop at a high rate following SBRT for spinal metastases from primary HCC, careful follow up of the patient is required. PMID:26484305

  15. Suppression of NADPH Oxidase Activity May Slow the Expansion of Osteolytic Bone Metastases.

    Lysophosphatidic acid (LPA), generated in the microenvironment of cancer cells, can drive the proliferation, invasion, and migration of cancer cells by activating G protein-coupled LPA receptors. Moreover, in cancer cells that have metastasized to bone, LPA signaling can promote osteolysis by inducing cancer cell production of cytokines, such as IL-6 and IL-8, which can stimulate osteoblasts to secrete RANKL, a key promoter of osteoclastogenesis. Indeed, in cancers prone to metastasize to bone, LPA appears to be a major driver of the expansion of osteolytic bone metastases. Activation of NADPH oxidase has been shown to play a mediating role in the signaling pathways by which LPA, as well as RANKL, promote osteolysis. In addition, there is reason to suspect that Nox4 activation is a mediator of the feed-forward mechanism whereby release of TGF-beta from bone matrix by osteolysis promotes expression of PTHrP in cancer cells, and thereby induces further osteolysis. Hence, measures which can down-regulate NADPH oxidase activity may have potential for slowing the expansion of osteolytic bone metastases in cancer patients. Phycocyanin and high-dose statins may have utility in this regard, and could be contemplated as complements to bisphosphonates or denosumab for the prevention and control of osteolytic lesions. Ingestion of omega-3-rich flaxseed or fish oil may also have potential for controlling osteolysis in cancer patients. PMID:27571113

    Brain metastases are frequent in patients with advanced breast cancer and are associated with poor prognosis. However, unique molecular biomarkers have not yet been established. We hypothesized that microRNA-20b (miR-20b) plays a role in breast cancer brain metastasis. Our study cohort comprised of eleven breast cancer patients with brain metastasis and nine control patients (age, stage, and follow-up matched) with breast cancer without brain metastasis. Cases were reviewed microscopically to select tumor blocks with >50% tumor cells, RNA was extracted from formalin-fixed paraffin-embedded (FFPE) tumor tissue blocks and expression of miR-20b analyzed using qRT-PCR. We further tested the effect of miR-20b overexpression on colony formation and invasion in vitro using MCF-7 and MDA-MB-231 cells. In the patient-derived samples, miR-20b expression was significantly higher in brain metastases of breast cancer patients, compared to primary breast tumors as well as the patients without brain metastasis. miR-20b also significantly induced the colony formation and invasiveness of breast cancer cells. Further, miR-20b levels were observed to be high in brain-metastasizing cells, compared to bone-metastasizing cells. Together, our findings suggest a novel role of miR-20b in breast cancer brain metastasis that warrants further investigation for its potential to be developed as prognostic and/or therapeutic target.

    How metastases develop is not well understood and no genetic mutations have been reported as specific metastatic drivers. Here we have addressed the idea that epigenetic reprogramming by GLI-regulated pluripotent stemness factors promotes metastases. Using primary human colon cancer cells engrafted in mice, we find that transient expression of OCT4, SOX2, KLF4 +/- cMYC establishes an enhanced pro-metastatic state in the primary tumor that is stable through sequential engraftments and is transmitted through clonogenic cancer stem cells. Metastatic reprogramming alters NANOG methylation and stably boosts NANOG and NANOGP8 expression. Metastases and reprogrammed EMT-like phenotypes require endogenous NANOG, but enhanced NANOG is not sufficient to induce these phenotypes. Finally, reprogrammed tumors enhance GLI2, and we show that GLI2(high) and AXIN2(low), which are markers of the metastatic transition of colon cancers, are prognostic of poor disease outcome in patients. We propose that metastases arise through epigenetic reprogramming of cancer stem cells within primary tumors. PMID:26031752

    This study was designed in order to evaluate specific vitamin D receptor (VDR) genotypes as indicators of the likelihood of developing osseous metastases in breast cancer patients. Therefore, we determined polymorphisms of the VDR gene in a study group comprising 183 breast cancer patients. Specific fragments spanning over intron 8 and exon 9 of the VDR gene were amplified by polymerase chain reaction. The fragments were then incubated with each of the specific endonucleases APAI, BSMI or TAQI, respectively. The VDR gene polymorphisms were detected by the presence or absence of the particular restriction site using agarose gel electrophoresis. Statistical analyses revealed a significant correlation between both the VDR gene polymorphisms indicated as AA (absence of the APAI restriction site in both alleles) or TT (absence of the TAQI restriction site in both alleles), respectively, and the occurrence of bone metastases. Patients with the AA genotype have a 1.7-fold increased risk of developing bone metastases, whereas patients with the TT genotype have a 0.5-fold risk. Neither other genotypes nor allelic combinations displayed any further correlation with the clinical stage. The data suggest that the AA genotype of the VDR gene might be useful to identify breast cancer patients with a high probability of forming occult bone metastases who are considered to benefit from an adjuvant bone-protective therapy.

    Brain metastases are secondary intracranial lesions which occur more frequently than primary brain tumors. The four most abundant types of brain metastasis originate from primary tumors of lung cancer, colorectal cancer, breast cancer and renal cell carcinoma. As metastatic cells contain the molecular information of the primary tissue cells and IR spectroscopy probes the molecular fingerprint of cells, IR spectroscopy based methods constitute a new approach to determine the origin of brain metastases. IR spectroscopic images of 4 by 4 mm2 tissue areas were recorded in transmission mode by a FTIR imaging spectrometer coupled to a focal plane array detector. Unsupervised cluster analysis revealed variances within each cryosection. Selected clusters of five IR images with known diagnoses trained a supervised classification model based on the algorithm soft independent modeling of class analogies (SIMCA). This model was applied to distinguish normal brain tissue from brain metastases and to identify the primary tumor of brain metastases in 15 independent IR images. All specimens were assigned to the correct tissue class. This proof-of-concept study demonstrates that IR spectroscopy can complement established methods such as histopathology or immunohistochemistry for diagnosis. PMID:16787638

    Pancreatic metastases are rare, with a reported incidence varying from 1.6% to 11% in autopsy studies of patients with advanced malignancy. In clinical series, the frequency of pancreatic metastases ranges from 2% to 5% of all pancreatic malignant tumors. However, the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies. The epidemiology, clinical presentation, and treatment of pancreatic metastases from renal cell carcinoma are known from single-institution case reports and literature reviews. There is currently very limited experience with the surgical resection of isolated pancreatic metastasis, and the role of surgery in the management of these patients has not been clearly defined. In fact, for many years pancreatic resections were associated with high rates of morbidity and mortality, and metastatic disease to the pancreas was considered to be a terminal-stage condition. More recently, a significant reduction in the operative risk following major pancreatic surgery has been demonstrated, thus extending the indication for these operations to patients with metastatic disease.

    Liver and pulmonary metastases (PMs) are relatively common in patients with colorectal cancer. The majority of metastases are suitable for surgical resection, and the effectiveness of metastasectomy is usually assessed based on overall survival (OS). Metastasectomy provides a mean 5-year OS rate of approximately 50%, but the results are better in patients with liver metastases compared to those with PMs. Unfortunately, the presence of bilateral or multiple PMs represents a relative contraindication to surgical metastasectomy. Unresectable PMs can be safely treated with percutaneous radiofrequency ablation or radiotherapy, but the reported results vary widely. Several clinical prognostic factors affecting OS after metastasectomy have been reported, such as number of PMs, hilar or mediastinal lymph node involvement, disease-free interval, age and gender, resection margins, size of the metastases, neoadjuvant chemotherapy administration, and histological type of the primary cancer. The accurate evaluation of all clinical prognostic factors, circulating and immunohistochemical markers, and the study of gene mutational status will lead to a more accurate selection of patients scheduled to metastasectomy, with the aim of improving outcome.

    Recent genomic studies challenge the conventional model that each metastasis must arise from a single tumor cell and instead reveal that metastases can be composed of multiple genetically distinct clones. These intriguing observations raise the question: How do polyclonal metastases emerge from the primary tumor? In this study, we used multicolor lineage tracing to demonstrate that polyclonal seeding by cell clusters is a frequent mechanism in a common mouse model of breast cancer, accounting for >90% of metastases. We directly observed multicolored tumor cell clusters across major stages of metastasis, including collective invasion, local dissemination, intravascular emboli, circulating tumor cell clusters, and micrometastases. Experimentally aggregating tumor cells into clusters induced a >15-fold increase in colony formation ex vivo and a >100-fold increase in metastasis formation in vivo. Intriguingly, locally disseminated clusters, circulating tumor cell clusters, and lung micrometastases frequently expressed the epithelial cytoskeletal protein, keratin 14 (K14). RNA-seq analysis revealed that K14(+) cells were enriched for desmosome and hemidesmosome adhesion complex genes, and were depleted for MHC class II genes. Depletion of K14 expression abrogated distant metastases and disrupted expression of multiple metastasis effectors, including Tenascin C (Tnc), Jagged1 (Jag1), and Epiregulin (Ereg). Taken together, our findings reveal K14 as a key regulator of metastasis and establish the concept that K14(+) epithelial tumor cell clusters disseminate collectively to colonize distant organs.

    Because the lung is a major target organ of metastatic disease, animal models to study the physiology of pulmonary metastases are of great importance. However, very few methods exist to date to investigate lung metastases in a dynamic fashion at the microcirculatory level, due to the difficulty to access the lung with a microscope. Here, an intravital microscopy method is presented to functionally image and quantify the microcirculation of superficial pulmonary metastases in rats, using a closed-chest pulmonary window and automated analysis of blood flow velocity and direction. The utility of this method is demonstrated to measure increases in blood flow velocity in response to pharmacological intervention, and to image the well-known tortuous vasculature of solid tumors. This is the first demonstration of intravital microscopy on pulmonary metastases in a closed-chest model. Because of its minimized invasiveness, as well as due to its relative ease and practicality, this technology has the potential to experience widespread use in laboratories that specialize on pulmonary tumor research.

    The prognosis for patients with melanoma who have brain metastases is poor, a median survival does not exceed 4-6 months. There are no uniform standards of treatment for patients with melanoma brain metastases (MBMs). The most preferred treatment approaches include local therapy - surgical resection and/or stereotactic radiosurgery (SRS). The role of whole brain radiotherapy (WBRT) as an adjuvant to local therapy is controversial. WBRT remains a palliative approach for those patients who have multiple MBMs with contraindications for surgery or SRS, or/and poor performance status, or/and very widespread extracranial metastases. Corticosteroids have been used in palliative treatment of MBMs as relief from symptoms related to intracranial pressure and edema. In recent years, the development of new systemic therapeutic strategies has been observed. Various modalities of systemic treatment include chemotherapy, immunotherapy and targeted therapy. Also, multimodality management in different combinations is a common strategy. Decisions regarding the use of specific treatment modalities are dependent on patient's performance status, and the extent of both intracranial and extracranial disease. This review summarizes current treatment options, indications and outcomes in patients with brain metastases from melanoma. PMID:27601961

    Breast cancer (BC) is the most common female cancer worldwide with approximately 10 % of new cases metastatic at diagnosis and 20-50 % of patients with early BC who will eventually develop metastatic disease. Bone is the most frequent site of colonisation and the development of skeletal metastases depends on a complex multistep process, from dissemination and survival of malignant cells into circulation to the actual homing and metastases formation inside bone. Disseminated tumor cells (DTCs) can be detected in bone marrow in approximately 30 % of BC patients, likely reflecting the presence of minimal residual disease that would eventually account for subsequent metastatic disease. Patients with bone marrow DTCs have poorer overall survival compared with patients without them. Although bone-only metastatic disease seems to have a rather indolent behavior compared to visceral disease, bone metastases can cause severe and debilitating effects, including pain, spinal cord compression, hypercalcemia and pathologic fractures. Delivering an appropriate treatment is therefore paramount and ideally it should require interdisciplinary care. Multiple options are currently available, from bisphosphonates to new drugs targeting RANK ligand and radiotherapy. In this review we describe the mechanisms underlying bone colonization and provide an update on existing systemic and locoregional treatments for bone metastases. PMID:26343511

    Minute (<5 mm) and small (5–10 mm) rectal carcinoids discovered during colonoscopy are generally considered to be non-aggressive, and the management and surveillance of patients with this entity are usually limited. We present the case of a 61-year-old Chinese female with multiple sub-5 mm carcinoid tumours in the rectum without any computed tomography (CT) evidence of lymph node or distant metastases. She underwent an ultra-low anterior resection for a sessile rectal polyp with the histological appearance of a moderately differentiated adenocarcinoma. Seven foci of minute carcinoids in the rectum and perirectal lymph node metastastic spread from the carcinoid tumours were also discovered on histopathology. There were no lymph node metastases originating from adenocarcinoma. This case report and review of the literature suggests that minute rectal carcinoids are at risk of metastasizing and that these patients should be investigated for lymph node and distant metastatic spread with CT and somatostatin receptor scintigraphy or its equivalent, as this would influence prognosis and surgical management of these patients. Findings relating to lymphovascular invasion, perineural invasion, high Ki-67, mitotic rate, depth of tumour invasion, central ulceration, multifocal tumours and size are useful in predicting metastases and may be used in scoring tools. Size alone is not a good predictor of metastastic spread. PMID:25342710

    Purpose: To determine the maximum tolerated dose (MTD) of stereotactic body radiation therapy (SBRT) for liver metastases. Methods and Materials: A multicenter Phase I clinical trial was conducted. Eligible patients had one to three liver metastases, tumor diameter <6 cm, and adequate liver function. The first cohort received 36 Gy to the planning target volume (PTV) in three fractions (F). Subsequent cohorts received higher doses up to a chosen maximum of 60 Gy/3F. At least 700 mL of normal liver had to receive a total dose <15 Gy. Dose-limiting toxicity (DLT) included acute Grade 3 liver or intestinal toxicity or any acute Grade 4 toxicity. The MTD was exceeded if 2/6 patients in a cohort experienced DLT. Results: Eighteen patients were enrolled (10 male, 8 female): median age, 55 years (range, 26-83 years); most common primary site, colorectal (6 patients); median aggregate gross tumor volume, 18 ml (range, 3-98 ml). Four patients had multiple tumors. No patient experienced a DLT, and dose was escalated to 60 Gy/3F without reaching MTD. Conclusions: Biologically potent doses of SBRT are well tolerated in patients with limited liver metastases. Results of this study form the basis for an ongoing Phase II SBRT study of 60 Gy over three fractions for liver metastases.

    Purpose: The Dutch Bone Metastases Study Group developed a survival prediction model in patients with symptomatic spinal bone metastases to guide the treating physician. The objective of this study was to validate the Dutch model and compare with our previously developed survival model at the Rapid Response Radiotherapy Program (RRRP model). Methods and Materials: The following prognostic factors were extracted from a prospective database in an outpatient palliative radiotherapy clinic: Karnofsky Performance Scores (KPS), primary cancer site, and visceral involvement for the Dutch model; primary cancer site, site of metastases, KPS, fatigue, appetite, and shortness of breath scores in the Edmonton Symptom Assessment Scale for the RRRP model. Patients were assigned scores according to each model. The survival probabilities were generated and calibration was performed for each model. Results: A total of 231 patients with spinal bone metastases from 1999 and 2002 were included in the analysis. The survival probabilities were similar to those in the original models. The calibration comparing actual survival with predicted survival from the Dutch and RRRP models gave R{sup 2} values of 0.90 and 0.86, respectively. Conclusion: The two models were successfully validated. The Dutch model using three clinical prognostic factors was easier to administer.

    Bone metastasis causes significant morbidity in cancer patients, including bone pain, pathologic fractures, nerve compression syndrome, and hypercalcemia. Animal models are utilized to study the pathogenesis of skeletal metastases and to evaluate potential therapeutic agents. Previously published methods for imaging bone metastasis in rodent models have focused on identifying advanced stage metastasis using simple X-rays. Here we report MRI as a method for detecting early bone metastases in mouse models in vivo. B16 mouse melanoma cells were injected into the left cardiac ventricle of C57BL/6 mice and magnetic resonance (MR) images were obtained of the left leg following the development of metastatic disease, when tumor associated bone destruction was histologically present but not visible by X-ray. T1 and T2 relaxation times of bone marrow were measured in healthy control mice and B16 melanoma tumor-bearing mice. Mean T2 values for normal marrow were 28 ms (SD 5) and for diseased bone marrow were 41 ms (SD 3). T2 relaxation time of diseased bone marrow is significantly longer than that of normal bone marrow (P < 0.0001) and can be used as a marker of early bone metastases. These studies demonstrate that MR imaging can detect bone marrow metastases in small animals prior to development of cortical bone loss identified by X-ray. PMID:16283483

    Purpose: To determine the indication and outcomes for Gamma Knife stereotactic radiosurgery (GKSRS) in the care of patients with intracranial sarcomatous metastases. Methods and Materials: Data from 21 patients who underwent radiosurgery for 60 sarcomatous intracranial metastases (54 parenchymal and 6 dural-based) were studied. Nine patients had radiosurgery for solitary tumors and 12 for multiple tumors. The primary pathology was metastatic leiomyosarcoma (4 patients), osteosarcoma (3 patients), soft-tissue sarcoma (5 patients), chondrosarcoma (2 patients), alveolar soft part sarcoma (2 patients), and rhabdomyosarcoma, Ewing's sarcoma, liposarcoma, neurofibrosarcoma, and synovial sarcoma (1 patient each). Twenty patients received multimodality management for their primary tumor, and 1 patient had no evidence of systemic disease. The mean tumor volume was 6.2 cm{sup 3} (range, 0.07-40.9 cm{sup 3}), and a median margin dose of 16 Gy was administered. Three patients had progressive intracranial disease despite fractionated whole-brain radiotherapy before SRS. Results: A local tumor control rate of 88% was achieved (including patients receiving boost, up-front, and salvage SRS). New remote brain metastases developed in 7 patients (33%). The median survival after diagnosis of intracranial metastasis was 16 months, and the 1-year survival rate was 61%. Conclusions: Gamma Knife radiosurgery was a well-tolerated and initially effective therapy in the management of patients with sarcomatous intracranial metastases. However, many patients, including those who also received fractionated whole-brain radiotherapy, developed progressive new brain disease.

    Detection and segmentation of ovarian cancer metastases have great clinical impacts on women’s health. However, the random distribution and weak boundaries of metastases significantly complicate this task. This paper presents a variational framework that combines region competition based level set propagation and image matching flow computation to jointly detect and segment metastases. Image matching flow not only detects metastases, but also creates shape priors to reduce over-segmentation. Accordingly, accurate segmentation helps to improve the detection accuracy by separating flow computation in metastasis and non-metastasis regions. Since all components in the image processing pipeline benefit from each other, our joint framework can achieve accurate metastasis detection and segmentation. Validation on 50 patient datasets demonstrated that our joint approach was superior to a sequential method with sensitivity 89.2% vs. 81.4% (Fisher exact test p = 0.046) and false positive per patient 1.04 vs. 2.04. The Dice coefficient of metastasis segmentation was 92 ± 5.2% vs. 72 ± 8% (paired t-test p = 0.022), and the average surface distance was 1.9±1.5mm vs. 4.5±2.2mm (paired t-test p = 0.004).

    The development of ultrasound contrast agents with excellent tolerance and safety profiles has notably improved liver evaluation with ultrasound (US) for several applications, especially for the detection of metastases. In particular, contrast enhanced ultrasonography (CEUS) allows the display of the parenchymal microvasculature, enabling the study and visualization of the enhancement patterns of liver lesions in real time and in a continuous manner in all vascular phases, which is similar to contrast-enhanced computed tomography (CT) and contrast-enhanced magnetic resonance imaging. Clinical studies have reported that the use of a contrast agent enables the visualization of more metastases with significantly improved sensitivity and specificity compared to baseline-US. Furthermore, studies have shown that CEUS yields sensitivities comparable to CT. In this review, we describe the state of the art of CEUS for detecting colorectal liver metastases, the imaging features, the literature reports of metastases in CEUS as well as its technique, its clinical role and its potential applications. Additionally, the updated international consensus panel guidelines are reported in this review with the inherent limitations of this technique and best practice experiences. PMID:25110428

    Purpose: To evaluate the outcomes associated with stereotactic body radiotherapy (SBRT) in the management of spinal metastases from renal cell carcinoma (RCC). Methods and Materials: SBRT was used in the treatment of patients with spinal metastases from RCC. Patients received either 24 Gy in a single fraction, 27 Gy in three fractions, or 30 Gy delivered in five fractions. Effectiveness of SBRT with respect to tumor control and palliation of pain was assessed using patient-reported outcomes. Results: A total of 48 patients with 55 spinal metastases were treated with SBRT with a median follow-up time of 13.1 months (range, 3.3-54.5 months). The actuarial 1-year spine tumor progression free survival was 82.1%. At pretreatment baseline, 23% patients were pain free; at 1 month and 12 months post-SBRT, 44% and 52% patients were pain free, respectively. No Grade 3-4 neurologic toxicity was observed. Conclusions: The data support SBRT as a safe and effective treatment modality that can be used to achieve good tumor control and palliation of pain associated with RCC spinal metastases. Further evaluation with randomized trials comparing SBRT to conventional radiotherapy may be warranted.

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

    Described here is an immunohistochemical technique using the commercially available monoclonal progesterone receptor (PR) antibody KD 68 in routinely fixed and paraffin-embedded breast carcinomas and lymph node metastases. The authors' technique is compared with several incubation variations. The method applying the primary antibody in a dilution of 1:10 overnight followed by a biotinylated second antibody showed the best results when Triton X-100 was added to the buffer. Using this method, comparison with the results on frozen sections of 34 breast carcinomas yielded a significant concordance of 94%. Correlation between the results on paraffin sections and those obtained by the standard dextran-coated charcoal cytosol assay was 80%. The value of the method for predicting endocrine therapy response was shown in 20 patients. Thus the reliability of the method has been demonstrated and was applied on 151 lymph node metastases and the corresponding primary breast carcinomas from 50 patients. Generally PR content in the metastases was lower than in the primary tumors (p < 0.001). This finding indicates that evaluation of PR in lymph node metastases should be included in the decision for endocrine therapy of breast cancer. PMID:7686056

    A 55-year-old woman with metastatic human epidermal growth factor receptor 2 (HER-2) positive breast cancer (BC) to the lungs and bones was diagnosed with central nervous system (CNS) metastases in November 2011. The MRI showed a right parietal lobe mass with adjacent leptomeningeal disease and several small bilateral cerebellar metastases. She was treated with whole brain irradiation (WBI), followed by capecitabine and lapatinib (December 2011-March 2013) and trastuzumab and lapatinib (May 2013-August 2013). Then, the brain MRI showed progression. In the absence of significant neurological symptoms, we postponed WBI and closely monitored for the development of neurological symptoms. Systemic treatment with trastuzumab emtansine (T-DM1), an antibody-drug conjugate composed of the cytotoxic agent DM1 conjugated to trastuzumab, was initiated in September 2013 to control systemic disease. Unexpectedly, after two cycles of treatment the brain MRI showed a decrease in size of CNS metastases. This case report suggests possible activity of T-DM1 in HER-2 positive BC with CNS metastases.

    Bone metastases from gastric cancer (GC) are considered a relatively uncommon finding; however, they are related to poorer prognosis. Both primary GC and its metastatic progression rely on angiogenesis. Several lines of evidence from GC patients strongly support the involvement of mast cells (MCs) positive to tryptase (MCPT) in primary gastric tumor angiogenesis. Recently, we analyzed infiltrating MCs and neovascularization in bone tissue metastases from primary GC patients, and observed a significant correlation between infiltrating MCPT and angiogenesis. Such a finding suggested the involvement of peritumoral MCPT by infiltrating surrounding tumor cells, and in bone metastasis angiogenesis from primary GC. Thus, an MCPT-stimulated angiogenic process could support the development of metastases in bone tissue. From this perspective, we aim to review the hypothetical involvement of tumor-infiltrating, peritumoral MCPT in angiogenesis-mediated GC cell growth in the bone microenvironment and in tumor-induced osteoclastic bone resorption. We also focus on the potential use of MCPT targeting agents, such as MCs tryptase inhibitors (gabexate mesylate, nafamostat mesylate) or c-KitR tyrosine kinase inhibitors (imatinib, masitinib), as possible new anti-angiogenic and anti-resorptive strategies for the treatment of GC patients affected by bone metastases.

    At the time of diagnosis, 25% of patients with colorectal cancer (CRC) present with synchronous metastases, which are unresectable in the majority of patients. Whether primary tumor resection (PTR) followed by chemotherapy or immediate chemotherapy without PTR is the best therapeutic option in patients with asymptomatic CRC and unresectable metastases is a major issue, although unanswered to date. The aim of this study was to review all published data on whether PTR should be performed in patients with CRC and unresectable synchronous metastases. All aspects of the management of CRC were taken into account, especially prognostic factors in patients with CRC and unresectable metastases. The impact of PTR on survival and quality of life were reviewed, in addition to the characteristics of patients that could benefit from PTR and the possible underlying mechanisms. The risks of both approaches are reported. As no randomized study has been performed to date, we finally discussed how a therapeutic strategy’s trial should be designed to provide answer to this issue. PMID:24936226

    Thirty (3.8%) of 780 patients with differentiated thyroid cancer seen between 1970 and 1987 had bone metastases. The primary tumor was follicular in 26 patients and papillary in four. Mean age at diagnosis was 61 years. The manifestation of bone metastases was the presenting symptom in 18 patients (60%). Treatment included total thyroidectomy, levothyroxine sodium therapy, and radioactive iodine treatments. Twenty-seven patients had bone metastases from the initial observation, with 44 sites involved. Of the sites, 27 (61%) were shown both on iodine 131 whole-body scan (WBS) and on x-ray film, 11 (25%) only on WBS, and six (14%) only on x-ray film. Multiple involvement was observed in 11 patients. The radiologic appearance was invariably osteolytic. Serum thyroglobulin was elevated in all patients. After radioactive iodine, no WBS+/X-ray+ metastases showed a complete response, although a sclerotic border was noted in several cases, whereas six WBS+/X-ray- lesions were no longer detectable by WBS. Treatment with radioactive iodine and bone surgery resulted in a complete cure in three patients and in a reduction of tumor mass in three. Twenty-one (70%) of the patients died of thyroid cancer after a mean survival of 86 months. Of the nine patients still alive, two are free of disease, three have a good quality of life, and four have severe disability.

    Background and objective: Systemic therapy for metastatic cancer is currently determined exclusively by the site of tumor origin. Yet, there is increasing evidence that the molecular characteristics of metastases significantly differ from the primary tumor. We define the evolutionary dynamics of metastases that govern this molecular divergence and examine their potential contribution to variations in response to targeted therapies. Methodology: Darwinian interactions of transformed cells with the tissue microenvironments at primary and metastatic sites are analyzed using evolutionary game theory. Computational models simulate responses to targeted therapies in different organs within the same patient. Results: Tumor cells, although maximally fit at their primary site, typically have lower fitness on the adaptive landscapes offered by the metastatic sites due to organ-specific variations in mesenchymal properties and signaling pathways. Clinically evident metastases usually exhibit time-dependent divergence from the phenotypic mean of the primary population as the tumor cells evolve and adapt to their new circumstances. In contrast, tumors from different primary sites evolving on identical metastatic adaptive landscapes exhibit phenotypic convergence. Thus, metastases in the liver from different primary tumors and even in different hosts will evolve toward similar adaptive phenotypes. The combination of evolutionary divergence from the primary cancer phenotype and convergence towards similar adaptive strategies in the same tissue cause significant variations in treatment responses particularly for highly targeted therapies. Conclusion and implications: The results suggest that optimal therapies for disseminated cancer must take into account the site(s) of metastatic growth as well as the primary organ. PMID:25794501

    Purpose. The purpose of this study was to analyze the expression of zinc-finger E-box-binding homeobox 1 (ZEB1) in endometrial biopsy and its correlation with preoperative characteristics, including lymph node metastases in patient with endometrial cancer. Methods. Using quantitative RT-PCR, ZEB1 expressions in endometrial biopsy from 452 patients were measured. The relationship between ZEB1 expression and preoperative characteristics was analyzed. Results. ZEB1 expressions were significantly associated with subtype, grade, myometrial invasion, and lymph node metastases. Lymph node metastases could be identified with a sensitivity of 57.8% at specificity of 74.1% by ZEB1 expression in endometrial biopsy. Based on combination of preoperative characteristics and ZEB1 expression, lymph node metastases could be identified with a sensitivity of 62.1% at specificity of 96.2% prior to hysterectomy. Conclusion. ZEB1 expression in endometrial biopsy could help physicians to better predict the lymph node metastasis in patients with endometrial cancer prior to hysterectomy. PMID:25544793

    Purpose: The aim of the study was to present a new breast cancer recursive partitioning analysis (RPA) prognostic index for patients with newly diagnosed brain metastases as a guide in clinical decision making. Methods and Materials: A prospectively collected group of 441 consecutive patients with breast cancer and brain metastases treated between the years 2003 and 2009 was assessed. Prognostic factors significant for univariate analysis were included into RPA. Results: Three prognostic classes of a new breast cancer RPA prognostic index were selected. The median survival of patients within prognostic Classes I, II, and III was 29, 9, and 2.4 months, respectively (p < 0.0001). Class I included patients with one or two brain metastases, without extracranial disease or with controlled extracranial disease, and with Karnofsky performance status (KPS) of 100. Class III included patients with multiple brain metastases with KPS of {<=}60. Class II included all other cases. Conclusions: The breast cancer RPA prognostic index is an easy and valuable tool for use in clinical practice. It can select patients who require aggressive treatment and those in whom whole-brain radiotherapy or symptomatic therapy is the most reasonable option. An individual approach is required for patients from prognostic Class II.

    Purpose: To examine prospectively patient self-rated symptoms and quality of life (QOL) indicators in patients with brain metastases following whole brain radiotherapy (WBRT). Methods and Materials: Consecutive patients with brain metastases referred for WBRT were approached for this study. Patients were asked to rate their symptoms and QOL using the Spitzer Quality of Life Index questionnaire. Follow-up was at 1, 2, and 3 months following WBRT. Linear regression analysis was used to determine the change in symptom severity over time. Results: Between August 2005 to October 2007, 129 patients with brain metastases were enrolled. The majority of patients (88%) received 20 Gy in five fractions. Median age was 64 years, and median Karnofsky Performance Status at baseline was 70. The most commonly experienced symptoms at baseline were headaches, weakness, balance problems, and fatigue. Thirty-five percent of patients rated neurological functional (NF) status as 1, indicating moderate neurological symptoms and need for assistance. Forty-three percent of patients had stable or decreased fatigue, and 47% had a stable or improved NF status over time (p = 0.0040). Although certain QOL domains improved over time, all other QOL domains and symptom items did not change significantly following WBRT. Conclusion: WBRT may have contributed to symptom stabilization in our study. An alternative goal of WBRT may be the prevention of symptom progression and QOL deterioration. Further research is required to select the most appropriate group of patients with brain metastases who would benefit most from WBRT.

    Background 70 years ago, it was put forward that the diseased liver was not a favorable soil for metastatic tumor cells. In addition, a few studies have demonstrated that rare occurrence of colorectal liver metastases among patients with fatty liver, cirrhosis or chronic hepatitis B and C virus infection. We performed a meta-analysis to verify the association between the incidences of colorectal liver metastases with chronically diseased livers. Methods Relevant studies were identified by a search of electronic database PubMed, Cochrane Library, OVID, Web of Science and CNKI (up to February 24, 2014). Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using random- or fixed-effect models when appropriate. Meta-analysis and publication bias (Bgger's test) was evaluated with STATA 12.0. Results A total of 10,349 colorectal cancer patients from 10 studies were included. The meta-analysis result showed there was a significant difference in the incidences of colorectal liver metastases between patients with normal and chronically diseased livers (OR = 0.32; 95% CI 95%: 0.26–0.38, P = 0.000 fixed-effects model). The result of Begg's test (Pr>|z| = 0.089; P>0.05) revealed no publication bias. Conclusions The results of this meta-analysis demonstrated that patients with chronically diseased livers had significantly lower incidences of colorectal liver metastases than those with normal livers.

    Purpose: Throughout the years, the palliative treatment of bone metastases using bone seeking radiotracers has been part of the therapeutic resources used in oncology, but the choice of which bone seeking agent to use is not consensual across sites and limited data are available comparing the characteristics of each radioisotope. Computational simulation is a simple and practical method to study and to compare a variety of radioisotopes for different medical applications, including the palliative treatment of bone metastases. This study aims to evaluate and compare 11 different radioisotopes currently in use or under research for the palliative treatment of bone metastases using computational methods. Methods: Computational models were used to estimate the percentage of deoxyribonucleic acid (DNA) damage (fast Monte Carlo damage algorithm), the probability of correct DNA repair (Monte Carlo excision repair algorithm), and the radiation-induced cellular effects (virtual cell radiobiology algorithm) post-irradiation with selected particles emitted by phosphorus-32 ({sup 32}P), strontium-89 ({sup 89}Sr), yttrium-90 ({sup 90}Y ), tin-117 ({sup 117m}Sn), samarium-153 ({sup 153}Sm), holmium-166 ({sup 166}Ho), thulium-170 ({sup 170}Tm), lutetium-177 ({sup 177}Lu), rhenium-186 ({sup 186}Re), rhenium-188 ({sup 188}Re), and radium-223 ({sup 223}Ra). Results: {sup 223}Ra alpha particles, {sup 177}Lu beta minus particles, and {sup 170}Tm beta minus particles induced the highest cell death of all investigated particles and radioisotopes. The cell survival fraction measured post-irradiation with beta minus particles emitted by {sup 89}Sr and {sup 153}Sm, two of the most frequently used radionuclides in the palliative treatment of bone metastases in clinical routine practice, was higher than {sup 177}Lu beta minus particles and {sup 223}Ra alpha particles.

    Integrins are cell surface adhesion molecules (CAM) that regulate via intercellular and cell-matrix signaling various cellular processes including wound healing, cell differentiation, division, growth, migration and metastatic dissemination. Although a correlation between carcinogenesis and changes in integrin expression, especially β1 integrin, has been reported, its role in colorectal liver metastases remains unclear. This study aimed to evaluate the expression of β1 integrin in colorectal liver metastases and to correlate the pattern of expression with clinicopathological features and to investigate the putative role of β1 integrin expression on survival of these patients. Methods: Formalin-fixed, paraffin-embedded (FFPE) tumor samples of 81 patients who were operated because of colorectal liver metastases without any neoadjuvant therapy were obtained and stained with hematoxylin and eosin (H & E). An immunohistochemical examination was performed using Dako, Peroxidase/DAB kit and a primary monoclonal β1 integrin (CD29, fibronectin receptor subunit beta; ab3167, Abcam plc). β1 integrin expression was evaluated according to the immunoreactive score of Remmele and Stegner and was related with clinicopathological features of prognostic significance and with disease-free and overall survival as well. Statistical analysis was performed using SPSS version 21.0. Results: β1 integrin was overexpressed in tumor cells in 37 (48%) patients and in stromal cell in 27 (33%) patients. The β1 expression was not statistically correlated with clinicopathological features of the primary tumors but it was statistically correlated (p=0.03) with the histological grading of liver metastases. Kaplan-Meier survival analysis showed that there is a tendency but no statistically significant correlation in disease-free and overall survival. Conclusion: Considering that expression of β1 integrin in colorectal liver metastases remains controversial, specially its relation with

    Meningeal metastasis is a fatal complication of breast cancer that affects 5-8% of patients. When cancer cells seed in the meninges, their subsequent growth results in severe neurological complications involving the cranial nerves, cerebrum and spinal cord, limiting life expectancy to less than 4 months. The incidences of meningeal metastases increase with prolonged lifespan resulting from treatment advances for primary breast cancer and their metastases. Currently, there is no cure. Aggressive multimodal therapies such as radiation and chemotherapy (intra-cerebrospinal fluid (CSF) and systemic) are ineffective. Therapeutic agents are often quickly cleared from the CSF, while higher doses that can achieve a therapeutic response are highly toxic. The secure guarding of the subarachnoid space by the blood-brain barrier on one side and the blood-CSF barrier on the other prevents chemotherapy from reaching cancer cells in the meninges. These challenges with treating meningeal metastases highlight the urgent need for a new therapeutic modality. An ideal treatment would be an agent that avoids rapid clearance, remains within the CSF, reaches the meninges and selectively destroys tumor cells. Replication conditional oncolytic herpes simplex virus type 1 (HSV-1) may be effective in this regard. Viral oncolysis, the destruction of cancer cells by replicating virus, is under clinical investigation for cancers that are unresponsive to current therapies. It is based on the model of multiple cycles of lytic virus replication in cancer cells that amplify the injected dose. The therapeutic potential of oncolytic HSV-1 for breast cancer meningeal metastases is discussed here. HSV-1 could be a potential novel treatment for meningeal metastases that can be translated to the clinic. PMID:26384139

    Background The purpose of the study was to evaluate the value of diffusion-weighted imaging in the differential diagnosis of haemangiomas from metastases of the liver. Patients and methods. We analyzed 69 lesions in 38 patients (33 haemangiomas; 36 metastases) in the retrospective study. Diffusion-weighted imaging was performed using a breath-hold single-shot echo-planar spin echo sequence with three b factors (0, 500 and 1000 sec/mm2), and apparent diffusion coefficients (ADCs) were calculated. For the quantitative evaluation, signal intensity of the lesions, lesion-to-liver signal intensity ratios, ADC of the lesions, and lesion-to-liver ADC ratios were compared between the groups. The statistical significance was determined by student’s-t test. Results With the b factor 500 sec/mm2, no statistical significance was achieved (p>0.05). With the b factor of 1000 sec/mm2, both the signal intensity and lesion-to-liver signal intensity ratio of the metastases were significantly higher than those for haemangiomas (p<0.001). The cut-off value at 2.6 yielded a sensitivity of 86% and a specificity of 82% for the lesion-to-liver signal intensity ratio. The ADC, and lesion-to-liver ADC ratio of the metastases were significantly lower than those of haemangiomas (p<0.001). With cut-off value of 1.7, ADC ratio had a sensitivity of 88% and a specificity of 72% for ADC lesion/liver. Conclusions Diffusion-weighted imaging with high b value may help in the differential diagnosis of metastases from haemangiomas of the liver. PMID:22933887

    There are many elements to the science that drives the clinical care of patients with brain metastases. Although part of an understanding that continues to evolve, a number of key historical misconceptions remain that commonly drive physicians' and researchers' attitudes and approaches. By understanding how these relate to current practice, we can better comprehend our available science to provide both better research and care. These past misconceptions include: Misconception 1: Once a primary cancer spreads to the brain, the histology of that primary tumor does not have much impact on response to chemotherapy, sensitivity to radiation, risk of further brain relapse, development of additional metastatic lesions, or survival. All tumor primary histologies are the same once they spread to the brain. They are the same in terms of the number of tumors, radiosensitivity, chemoresponsiveness, risk of further brain relapse, and survival. Misconception 2: The number of brain metastases matters. This number matters in terms of subsequent brain relapse, survival, and cognitive dysfunction; the precise number of metastases can also be used as a limit in determining which patients might be eligible for a particular treatment option. Misconception 3: Cancer in the brain is always a diffuse problem due to the presence of micrometastases. Misconception 4: Whole-brain radiation therapy invariably causes disabling cognitive dysfunction if a patient lives long enough. Misconception 5: Most brain metastases are symptomatic. Thus, it is not worth screening patients for brain metastases, especially because the impact on survival is minimal. The conduct and findings of past clinical research have led to conceptions that affect clinical care yet appear limiting. PMID:24662510

    Many patients with pancreatic cancer have metastases to distant organs at the time of initial presentation. Recent studies examining the evolution of pancreatic cancer at the genetic level have shown that clonal complexity of metastatic pancreatic cancer is already initiated within primary tumors, and organ-specific metastases are derived from different subclones. However, we do not yet understand to what extent the evolution of pancreatic cancer contributes to proteomic and signaling alterations. We hypothesized that genetic heterogeneity of metastatic pancreatic cancer results in heterogeneity at the proteome level. To address this, we employed a model system in which cells isolated from three sites of metastasis (liver, lung, and peritoneum) from a single patient were compared. We used a SILAC-based accurate quantitative proteomic strategy combined with high-resolution mass spectrometry to analyze the total proteome and tyrosine phosphoproteome of each of the distal metastases. Our data revealed distinct patterns of both overall proteome expression and tyrosine kinase activities across the three different metastatic lesions. This heterogeneity was significant because it led to differential sensitivity of the neoplastic cells to small molecule inhibitors targeting various kinases and other pathways. For example, R428, a tyrosine kinase inhibitor that targets Axl receptor tyrosine kinase, was able to inhibit cells derived from lung and liver metastases much more effectively than cells from the peritoneal metastasis. Finally, we confirmed that administration of R428 in mice bearing xenografts of cells derived from the three different metastatic sites significantly diminished tumors formed from liver- and lung-metastasis-derived cell lines as compared with tumors derived from the peritoneal metastasis cell line. Overall, our data provide proof-of-principle support that personalized therapy of multiple organ metastases in a single patient should involve the

    The objective of this study was to evaluate the dose conformity and feasibility of whole-brain radiotherapy with a simultaneous integrated boost by forward intensity-modulated radiation therapy in patients with 1 to 3 brain metastases. Forward intensity-modulated radiation therapy plans were generated for 10 patients with 1 to 3 brain metastases on Pinnacle 6.2 Treatment Planning System. The prescribed dose was 30 Gy to the whole brain (planning target volume [PTV]{sub wbrt}) and 40 Gy to individual brain metastases (PTV{sub boost}) simultaneously, and both doses were given in 10 fractions. The maximum diameters of individual brain metastases ranged from 1.6 to 6 cm, and the summated PTVs per patient ranged from 1.62 to 69.81 cm{sup 3}. Conformity and feasibility were evaluated regarding conformation number and treatment delivery time. One hundred percent volume of the PTV{sub boost} received at least 95% of the prescribed dose in all cases. The maximum doses were less than 110% of the prescribed dose to the PTV{sub boost}, and all of the hot spots were within the PTV{sub boost}. The volume of the PTV{sub wbrt} that received at least 95% of the prescribed dose ranged from 99.2% to 100%. The mean values of conformation number were 0.682. The mean treatment delivery time was 2.79 minutes. Ten beams were used on an average in these plans. Whole-brain radiotherapy with a simultaneous integrated boost by forward intensity-modulated radiation therapy in 1 to 3 brain metastases is feasible, and treatment delivery time is short.

  19. Metastases and Colon Cancer Tumor Growth Display Divergent Responses to Modulation of Canonical WNT Signaling

    2016-01-01

    Human colon cancers commonly harbor loss of function mutations in APC, a repressor of the canonical WNT pathway, thus leading to hyperactive WNT-TCF signaling. Re-establishment of Apc function in mice, engineered to conditionally repress Apc through RNAi, resolve the intestinal tumors formed due to hyperactivated Wnt-Tcf signaling. These and other results have prompted the search for specific WNT pathway antagonists as therapeutics for clinically problematic human colon cancers and associated metastases, which remain largely incurable. This widely accepted view seems at odds with a number of findings using patient-derived material: Canonical TCF targets are repressed, instead of being hyperactivated, in advanced colon cancers, and repression of TCF function does not generally result in tumor regression in xenografts. The results of a number of genetic mouse studies have also suggested that canonical WNT-TCF signaling drives metastases, but direct in vivo tests are lacking, and, surprisingly, TCF repression can enhance directly seeded metastatic growth. Here we have addressed the abilities of enhanced and blocked WNT-TCF signaling to alter tumor growth and distant metastases using xenografts of advanced human colon cancers in mice. We find that endogenous WNT-TCF signaling is mostly anti-metastatic since downregulation of TCF function with dnTCF generally enhances metastatic spread. Consistently, elevating the level of WNT signaling, by increasing the levels of WNT ligands, is not generally pro-metastatic. Our present and previous data reveal a heterogeneous response to modulating WNT-TCF signaling in human cancer cells. Nevertheless, the findings that a fraction of colon cancers tested require WNT-TCF signaling for tumor growth but all respond to repressed signaling by increasing metastases beg for a reevaluation of the goal of blocking WNT-TCF signaling to universally treat colon cancers. Our data suggest that WNT-TCF blockade may be effective in inhibiting tumor

    Background Stereotactic radiosurgery is a well-accepted treatment for patients with intracranial metastases, but outcomes with volumetric modulated arc radiosurgery (VMAR) are poorly described. Objective To report our initial clinical experience applying a novel single-isocenter technique to frameless VMAR for simultaneous treatment of multiple intracranial metastases. Methods We performed a retrospective analysis of 15 patients undergoing frameless VMAR for multiple intracranial metastases using a single, centrally-located isocenter between 2009 and 2011. Among these, 3 patients were treated for progressive or recurrent intracranial disease. A total of 62 metastases (median 3 per patient, range 2-13) were treated to a median dose of 20 Gy (range, 15-30 Gy). 3 patients were treated with fractionated SRS. Follow-up including clinical examination and magnetic resonance imaging (MRI) occurred every 3 months. Results Median follow-up for all patients was 7.1 months (range, 1.1-24.3), with 11 patients (73.3%) followed until death. For the remaining 4 patients alive at the time of analysis, median follow-up was 19.6 months (range, 9.2-24.3). Local control at 6 and 12 months was 91.7 (95% Confidence Interval [C.I.], 84.6-100.0%) and 81.5 (95% C.I., 67.9-100.0%), respectively. Regional failure was observed in 9 patients (60.0%), and 7 patients (46.7%) received salvage therapy. Overall survival at 6 months was 60.0% (95% C.I., 40.3-88.2%). Grade 3 or greater treatment-related toxicity was not observed. Median total treatment time was 7.2 minutes (range, 2.8-13.2 minutes). Conclusion Single-isocenter, frameless VMAR for multiple intracranial metastases is a promising technique that may provide similar clinical outcomes compared to conventional radiosurgery.

    2010-01-01

    Background The Triplex cell vaccine is a cancer cellular vaccine that can prevent almost completely the mammary tumor onset in HER-2/neu transgenic mice. In a translational perspective, the activity of the Triplex vaccine was also investigated against lung metastases showing that the vaccine is an effective treatment also for the cure of metastases. A future human application of the Triplex vaccine should take into account several aspects of biological behavior of the involved entities to improve the efficacy of therapeutic treatment and to try to predict, for example, the outcomes of longer experiments in order to move faster towards clinical phase I trials. To help to address this problem, MetastaSim, a hybrid Agent Based - ODE model for the simulation of the vaccine-elicited immune system response against lung metastases in mice is presented. The model is used as in silico wet-lab. As a first application MetastaSim is used to find protocols capable of maximizing the total number of prevented metastases, minimizing the number of vaccine administrations. Results The model shows that it is possible to obtain "in silico" a 45% reduction in the number of vaccinations. The analysis of the results further suggests that any optimal protocol for preventing lung metastases formation should be composed by an initial massive vaccine dosage followed by few vaccine recalls. Conclusions Such a reduction may represent an important result from the point of view of translational medicine to humans, since a downsizing of the number of vaccinations is usually advisable in order to minimize undesirable effects. The suggested vaccination strategy also represents a notable outcome. Even if this strategy is commonly used for many infectious diseases such as tetanus and hepatitis-B, it can be in fact considered as a relevant result in the field of cancer-vaccines immunotherapy. These results can be then used and verified in future "in vivo" experiments, and their outcome can be used to

    Background For breast and prostate cancer, a gene expression signature of the tumour is associated with the development of distant metastases. Regarding head and neck squamous cell carcinoma (HNSCC), the only known risk factor is the presence of ⩾3 tumour‐positive lymph nodes. Aim To evaluate whether a HNSCC gene expression signature can discriminate between the patients with and without distant metastases. Methods Patients with HNSCC with and without distant metastases had >3 tumour‐positive lymph nodes, and did not differ with respect to other risk factors. Statistical analysis was carried out using Student's t test, as well as statistical analysis of microarrays (SAM), to assess the false discovery rate for each gene. These analyses were supplemented with a newly developed method that computed deviations from gaussian‐order statistics (DEGOS). To validate the platform, normal mucosa of the head and neck was included as control. Results 2963 genes were differently expressed between HNSCC and normal mucosa (t test; p<0.01). More rigorous statistical analysis with SAM confirmed the differential expression of most genes. The comparison of genes in HNSCC with and without metastases showed 150 differently expressed genes (t test; p<0.01), none of which, however, could be confirmed using SAM or DEGOS. Conclusions No evidence for a metastasis signature is found, and gene expression profiling of HNSCC has seemingly no value in determining the risk of developing distant metastases. The absence of such a signature can be understood when it is realised that, for HNSCC in contrast with breast cancer, the lymph nodes are a necessary in‐between station for haematogenous spread.

    Background Total thyroidectomy is the treatment of choice for medullary thyroid carcinoma (MTC), but the extent of neck dissection is controversial. Lymph node metastases, distant metastases, and old age are known predictors of poor survival. Patients Patients treated for primary MTC at Helsinki University Hospital from 1990 to 2009 were included (n = 54). Their clinical characteristics, treatment, and outcome were analysed retrospectively, these patients were followed until death or their last follow-up date. Results At last follow-up (3.4-23 years), of 54 MTC patients, 19 (35%) were disease-free, 17 (32%) were alive with disease, and 12 (22%) had died of MTC; six patients died of unrelated causes (11%). All disease-free patients were node negative and had normal postoperative calcitonin level. Of 19 disease-free patients, only four (21%) had undergone lymph node dissection. All patients who died of MTC were Stage IV at diagnosis and died with distant metastases. Disease-specific five-and 10-year survival was 84% and 76.2%. Advanced T-stage (p = 0.004), lymph node metastases (p < 0.001), distant metastases (p < 0.001), stage (p < 0.001), and elevated postoperative calcitonin (p < 0.001) significantly associated with survival. Conclusions Lymph node metastasis and elevated postoperative calcitonin are important prognostic factors. Patients with lymph node metastasis and/or elevated postoperative calcitonin with present treatments cannot become disease-free, but most of them can live a long life with metastasis. PMID:26339947

    3.0Tesla magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) was compared with combined 18F-fluorodeoxyglucose positron emission tomography and computed tomography (PET/CT) in patients with suspected bone metastases from breast cancer. A prospective clinical study was performed in 13 female breast cancer patients (mean age 61years; range 45-85 years). The spine was imaged in the sagittal plane with T1-weighted (T1), short tau inversion recovery (STIR), and T2-weighted fat-saturated (T2) sequences. The pelvis was imaged similarly in the coronal plane. Axial DWI was performed from the skull base to the mid-thigh. MRI and PET/CT were performed in all patients at a maximum interval of 10 working days and at least 14 days after chemotherapy. MRI was reviewed by two radiologists, and their consensus on potential metastases in 27 predefined locations was recorded. The predefined locations were the vertebral bodies (24), the left (1) and right (1) pelvic bones, and the sacral bone (1). The PET/CT was reviewed by a radiologists and a nuclear medicine physician. MRI detected 59 of the 60 active metastases found with our gold standard modality PET/CT. T1 had the highest sensitivity (98%) but rather low specificity (77%), but with the addition of STIR and DWI, the specificity increased to 95%. The additional metastases detected with MRI most likely represented postherapeutic residual scars without active tumour. In conclusion, 3.0Tesla MRI with T1, STIR, and DWI is useful for the clinical evaluation of bone metastases from breast cancer and compares well to PET/CT. PMID:21227614

    The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No optimal

    Purpose: To prospectively compare the effect of prophylactic and therapeutic whole brain radiotherapy (WBRT) on memory function in patients with and without brain metastases. Methods and Materials: Adult patients with and without brain metastases (n = 44) were prospectively evaluated with serial cognitive testing, before RT (T0), after starting RT (T1), at the end of RT (T2), and 6-8 weeks (T3) after RT completion. Data were obtained from small-cell lung cancer patients treated with prophylactic cranial irradiation, patients with brain metastases treated with therapeutic cranial irradiation (TCI), and breast cancer patients treated with RT to the breast. Results: Before therapy, prophylactic cranial irradiation patients performed worse than TCI patients or than controls on most test scores. During and after WBRT, verbal memory function was influenced by pretreatment cognitive status (p < 0.001) and to a lesser extent by WBRT. Acute (T1) radiation effects on verbal memory function were only observed in TCI patients (p = 0.031). Subacute (T3) radiation effects on verbal memory function were observed in both TCI and prophylactic cranial irradiation patients (p = 0.006). These effects were more pronounced in patients with above-average performance at baseline. Visual memory and attention were not influenced by WBRT. Conclusions: The results of our study have shown that WBRT causes cognitive dysfunction immediately after the beginning of RT in patients with brain metastases only. At 6-8 weeks after the end of WBRT, cognitive dysfunction was seen in patients with and without brain metastases. Because cognitive dysfunction after WBRT is restricted to verbal memory, patients should not avoid WBRT because of a fear of neurocognitive side effects.

    Abstract The mutational profiles of primary colorectal cancers (CRCs) and corresponding ovarian metastases were compared. Using a custom‐made next generation sequencing panel, 115 cancer‐driving genes were analyzed in a cohort of 26 primary CRCs and 30 matching ovarian metastases (four with bilateral metastases). To obtain a complete overview of the mutational profile, low thresholds were used in bioinformatics analysis to prevent low frequency passenger mutations from being filtered out. A subset of variants was validated using Sanger and/or hydrolysis probe assays. The mutational landscape of CRC that metastasized to the ovary was not strikingly different from CRC in consecutive series. When comparing primary CRCs and their matching ovarian metastases, there was considerable overlap in the mutations of early affected genes. A subset of mutations demonstrated less overlap, presumably being passenger mutations. In particular, primary CRCs showed a substantially high number of passenger mutations. We also compared the primary CRCs and matching metastases for stratifying variants of six genes (KRAS, NRAS, BRAF, FBXW7, PTEN and PIK3CA) that select for established (EGFR directed) or future targeted therapies. In a total of 31 variants 12 were not found in either of the two locations. Tumours thus differed in the number of discordant variants between the primary tumours and matching metastases. Half of these discordant variants were definitive class 4/5 pathogenic variants. However, in terms of temporal heterogeneity, no clear relationship was observed between the number of discordant variants and the time interval between primary CRCs and the detection of ovarian metastases. This suggests that dormant metastases may be present from the early days of the primary tumours. PMID:27499925

    Clinicians generally suspect pulmonary tumor embolism (PTE) with uncontrolled carcinomas which often spread to lungs. We, however, experienced an autopsy case of diffuse microscopic PTE despite controlled liver metastases of transitional cell carcinoma (TCC). A 66-year-old man with progressing respiratory symptoms showed almost normal chest findings on computed tomography. Although liver metastases were successfully shrunk by chemotherapy, the patient died from aggressive respiratory failure. An autopsy revealed small pulmonary vessels showing diffuse tumor emboli. TCC can cause PTE even if liver metastases are controlled. We must therefore be aware that PTE can manifest as respiratory symptoms without any computed tomography findings. PMID:27580549

    The NADPH-dependent cytochrome P450 oxidoreductase (POR) is the obligate electron donor to eukaryotic microsomal cytochromes P450 enzymes. The number of PORs within plant species is limited to one to four isoforms, with the most common being two PORs per plant. These enzymes provide electrons to a huge number of different cytochromes P450s (from 50 to several hundred within one plant). Within the eudicotyledons, PORs can be divided into two major clades, POR 1 and POR 2. Based on our own sequencing analysis and publicly available data, we have identified 45 PORs from the angiosperm order Apiales. These were subjected to a phylogenetic analysis along with 237 other publicly available (NCBI and oneKP) POR sequences found within the clade Asterids. Here, we show that the order Apiales only harbor members of the POR 2 clade, which are further divided into two distinct subclades. This is in contrast to most other eudicotyledon orders that have both POR 1 and POR 2. This suggests that through gene duplications and one gene deletion, Apiales only contain members of the POR 2 clade. Three POR 2 isoforms from Thapsia garganica L., Apiaceae, were all full-length in an Illumina root transcriptome dataset (available from the SRA at NCBI). All three genes were shown to be functional upon reconstitution into nanodiscs, confirming that none of the isoforms are pseudogenes. PMID:26854662

    Background The development of metastases involves the dissociation of cells from the primary tumor to penetrate the basement membrane, invade and then exit the vasculature to seed, and colonize distant tissues. The last step, establishment of macroscopic tumors at distant sites, is the least well understood. Four isogenic mouse breast cancer cell lines (67NR, 168FARN, 4TO7, and 4T1) that differ in their ability to metastasize when implanted into the mammary fat pad are used to model the steps of metastasis. Only 4T1 forms macroscopic lung and liver metastases. Because some miRNAs are dysregulated in cancer and affect cellular transformation, tumor formation, and metastasis, we examined whether changes in miRNA expression might explain the differences in metastasis of these cells. Methodology/Principal Findings miRNA expression was analyzed by miRNA microarray and quantitative RT–PCR in isogenic mouse breast cancer cells with distinct metastatic capabilities. 4T1 cells that form macroscopic metastases had elevated expression of miR-200 family miRNAs compared to related cells that invade distant tissues, but are unable to colonize. Moreover, over-expressing miR-200 in 4TO7 cells enabled them to metastasize to lung and liver. These findings are surprising since the miR-200 family was previously shown to promote epithelial characteristics by inhibiting the transcriptional repressor Zeb2 and thereby enhancing E-cadherin expression. We confirmed these findings in these cells. The most metastatic 4T1 cells acquired epithelial properties (high expression of E-cadherin and cytokeratin-18) compared to the less metastatic cells. Conclusions/Significance Expression of miR-200, which promotes a mesenchymal to epithelial cell transition (MET) by inhibiting Zeb2 expression, unexpectedly enhances macroscopic metastases in mouse breast cancer cell lines. These results suggest that for some tumors, tumor colonization at metastatic sites might be enhanced by MET. Therefore the

    Purpose: Patients with bone metastases have a widely varying survival. A reliable estimation of survival is needed for appropriate treatment strategies. Our goal was to assess the value of simple prognostic factors, namely, patient and tumor characteristics, Karnofsky performance status (KPS), and patient-reported scores of pain and quality of life, to predict survival in patients with painful bone metastases. Methods and Materials: In the Dutch Bone Metastasis Study, 1157 patients were treated with radiation therapy for painful bone metastases. At randomization, physicians determined the KPS; patients rated general health on a visual analogue scale (VAS-gh), valuation of life on a verbal rating scale (VRS-vl) and pain intensity. To assess the predictive value of the variables, we used multivariate Cox proportional hazard analyses and C-statistics for discriminative value. Of the final model, calibration was assessed. External validation was performed on a dataset of 934 patients who were treated with radiation therapy for vertebral metastases. Results: Patients had mainly breast (39%), prostate (23%), or lung cancer (25%). After a maximum of 142 weeks' follow-up, 74% of patients had died. The best predictive model included sex, primary tumor, visceral metastases, KPS, VAS-gh, and VRS-vl (C-statistic = 0.72, 95% CI = 0.70-0.74). A reduced model, with only KPS and primary tumor, showed comparable discriminative capacity (C-statistic = 0.71, 95% CI = 0.69-0.72). External validation showed a C-statistic of 0.72 (95% CI = 0.70-0.73). Calibration of the derivation and the validation dataset showed underestimation of survival. Conclusion: In predicting survival in patients with painful bone metastases, KPS combined with primary tumor was comparable to a more complex model. Considering the amount of variables in complex models and the additional burden on patients, the simple model is preferred for daily use. In addition, a risk table for survival is provided.

    Pancreatic metastases from renal cell carcinoma are uncommon and their prognostic significance is not well defined. In this analysis we evaluated the outcome of patients with pancreatic metastases treated with either targeted therapies or local treatment to the pancreas. Patients with pancreatic metastases from renal cell carcinoma treated between 1993 and 2014 were identified from 11 European centers. Clinical records were retrospectively reviewed. Kaplan-Meier method and log-rank test were used to evaluate progression-free survival and overall survival. Cox's proportional hazard models were used for survival analysis. In total, 276 PM patients were evaluated, including 77 (28%) patients treated by either surgery or radiotherapy to the pancreas, and 256 (93%) who received systemic therapy. Median time from nephrectomy to diagnosis of pancreatic metastases was 91 months (IQR 54-142). Disease control rate after first-line TTs was 84%, with a median progression-free survival of 12 months (95% CI 10-14). Median overall survival was 73 months (95% CI 61-86) with a 5-year OS of 58%. Median OS of patients treated with local treatment was 106 months (95% CI 78-204) with a 5-year overall survival of 75%. On multivariable analysis, nephrectomy (HR 5.31; 95%CI 2.36-11.92; p<0.0001), Memorial Sloan Kettering/International Metastatic RCC Database Consortium prognostic score (HR 1.45, 95% CI 0.94-2.23 for intermediate vs good vs risk; HR 2.76 95%, CI 1.43-5.35 for poor vs good risk p = 0.0099) and pancreatic local treatment (HR 0.48; 95%CI 0.30-0.78 p = 0.0029) were associated with overall survival. Difference in median OS between patients with PM and that reported in a matched-control group of mRCC patients with extrapancreatic metastases was statistically significant (p < .0001).

    The administration of anti-B16 monoclonal antibody of the IgG2b isotype to mice bearing established B16 melanoma liver metastases caused a significant and consistent reduction of up to 90% in the number of these metastases. No reduction in the number of metastases was noted when antigenically unrelated tumor or nonspecific immunoglobulin were employed. The antibody-mediated antitumor effect was completely abrogated by total body irradiation of the host. Treatment of the tumor-bearing host with antiserum directed against asialo GM1 prior to anti B16 antibody administration, abrogated the therapeutic effect indicating the involvement of a radiosensitive, ASGM1-positive cell in the tumor regression. The antitumor effect of the antibody treatment could be augmented by the concomitant administration of recombinant interleukin-2. The effect seen may have possible application in the treatment of liver metastases in humans by combined immunotherapy using recombinant interleukin-2 and specific antitumor monoclonal antibodies.

Based on this limited number of studies, cutaneous metastases from gynecological malignancies are uncommon occurrences. Cutaneous metastases from the synchronous endometrioid carcinoma of the uterine corpus and bilateral ovaries arising from endometriosis are extremely rare. Herein, we report a 51-year-old woman with FIGO Stage 1A Grade 1 endometrial endometrioid-type adenocarcinoma and synchronous bilateral Stage 1B ovarian endometrioid-type adenocarcinoma who presented 34 months following total abdominal hysterectomy and bilateral salpingo-oophorectomy with skin metastases. After the patient underwent an excisional biopsy, we applied a palliative radiotherapy. The patient received the combination therapy with cisplatin and doxorubicin after the completion of radiotherapy but the disease evolution was rapidly fatal and the patient died 4 months after her admission to our department due to widely disseminated disease.

    A 69-year-old woman was diagnosed with descending colon cancer with multiple liver metastases, and a left hemicolectomy was performed. The patient was treated with capecitabine/oxaliplatin (CapeOX) plus bevacizumab (Bmab). After 5 courses of chemotherapy, the number and size of liver metastases remarkably reduced, and after the 12th course, because of peripheral neuropathy, a "stop-and-go"fashion of administering oxaliplatin (L-OHP) was initiated. After 14 courses, the liver metastases had disappeared. After the 33rd course of L-OHP treatment, the patient started receiving capecitabine therapy. The patient is recurrence-free 3 years after surgery, 14 months after achieving a complete response (CR). We report a case of long-term CR after surgery for descending colon cancer with multiple liver metastases, followed by a "stop-and-go" method of administering L-OHP or CapeOX plus Bmab therapy.

    Fewer than 2% of patients with metastatic prostate cancer (pca) develop brain metastases. Autopsy series have confirmed the rarity of brain metastases. When present, brain metastases occur in end stage, once the pca is castrate-resistant and spread to other sites is extensive. Here, we present a rare case of a patient with pca who developed a solitary parenchymal brain metastasis as first site of relapse 9 years after radical therapy. The patient underwent craniotomy and excision of the tumour. A second recurrence was also isolated to the brain. In the literature, pca patients with brain metastases have a poor mean survival of 1–7.6 months. The patient in our case report experienced a relatively favourable outcome, surviving 19 months after his initial brain relapse. PMID:26715888

    Pancreatic metastases are very uncommon and originate most commonly from lung, colon, breast and kidney cancer. Ovarian adenocarcinoma has been reported as a primary site of pancreatic metastasis, but its diagnosis has rarely being reported by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We report a case of multiple metastases to the pancreas from ovarian carcinoma occurring four years after original resection of the primary tumour. Our patient presented with severe epigastric pain which was initially treated as acute pancreatitis. Further imaging modalities showed multiple large pseudocystic lesions in the pancreatic head and body. Subsequent EUS-FNA confirmed that the lesions were metastatic disease from an advanced ovarian carcinoma. She underwent palliative chemotherapy and the pancreatic lesion showed receding size.

    Platelet-derived lysophosphatidic acid (LPA) supports the progression of breast and ovarian cancer metastasis to bone. The mechanisms through which LPA promotes bone metastasis formation are, however, unknown. Here we report that silencing of the type 1 LPA receptor (LPA1) in cancer cells blocks the production of tumor-derived cytokines that are potent activators of osteoclast-mediated bone destruction and significantly reduces the progression of osteolytic bone metastases. Moreover, functional blockade of LPA action on its cognate receptor LPA1 using a pharmacological antagonist mimics the effects of silencing LPA1 in tumor cells in vitro and substantially reduces bone metastasis progression in animals. Overall, these results suggest that inhibition of platelet-derived LPA action on LPA1 expressed by tumor cells may be a promising therapeutic target for patients with bone metastases. PMID:16769891

    Rhabdoid meningioma is a rare meningioma variant, classified as WHO grade III. Although this tumor is known for its aggressive behavior and poor prognosis, extracranial metastasis is rare. We report the rare case of a 31-year-old patient with rhabdoid meningioma which recurred several times despite gross total resection, radiation therapy, and gamma knife radiosurgery, and the last recurrence was associated with metastases to lungs, lymph node and bone. The patient showed no response to paclitaxel-carboplatin, or vincristine-cyclophosphamide-adriamycin chemotherapy, and succumbed to the disease. Metastases from rhabdoid meningioma prove to be a diagnostic challenge, and treatment for metastatic meningiomas is not optimized, thus necessitating documentation and interdisciplinary consensus on management protocols.

    Surgical resection is the only option of cure for patients with metastatic colorectal cancer (CRC). However, the risk of recurrence within 18 mo after metastasectomy is around 75% and the liver is the most frequent site of relapse. The current international guidelines recommend an adjuvant therapy after surgical resection of CRC metastases despite the lower level of evidence (based on the quality of studies in this setting). However, there is still no standard treatment and the effective role of an adjuvant therapy remains controversial. The aim of this review is to report the state-of-art of systemic chemotherapy and regional chemotherapy with hepatic arterial infusion in the management of patients after resection of metastases from CRC, with a literature review and meta-analysis of the relevant randomized controlled trials.

    We report a rare case involving a patient with C3 vertebral body metastasis secondary to adenoid cystic carcinoma of the tongue.Five years after local resection of the primary tumor, magnetic resonance imaging showed a metastasis located in the left posterior border of the C3 vertebral body. Additionally, multiple pulmonary metastases were identified by computed tomography. Based on these findings, the patient underwent C2-3, C3-4 discectomy; C3 corpectomy; and titanium mesh fusion with a Zephir plate. The diagnosis was confirmed by the pathology findings. During 6 months of follow-up, the patient showed improvement and return of function of the cervical vertebrae, with no serious complications.Because of the scarcity of cases of vertebral metastases from tumors of the tongue in the literature, we have reported this case to add to the available evidence regarding this rarely encountered condition.

    Glioblastoma (GBM) is an extremely aggressive, infiltrative tumor with a poor prognosis. The regulatory approval of bevacizumab for recurrent GBM has confirmed that molecularly targeted agents have potential for GBM treatment. Preclinical data showing that SRC and SRC-family kinases (SFKs) mediate intracellular signaling pathways controlling key biologic/oncogenic processes provide a strong rationale for investigating SRC/SFK inhibitors, eg, dasatinib, in GBM and clinical studies are underway. The activity of these agents against solid tumors suggests that they may also be useful in treating brain metastases. This article reviews the potential for using SRC/SFK inhibitors to treat GBM and brain metastases. Word count =99/100 PMID:20947248

    Adenoid cystic carcinoma (ACC) of the breast is a rare malignant salivary-type neoplasm that has a good prognosis and represents less than 1% of all breast cancers. It is a triple negative carcinoma that presents as a painful mass. The mean age at the time of diagnosis is 50–60 years old. The solid variant of this type of tumour with basaloid features and presence of nodal metastases is very rare and considered to have a more aggressive clinical course. We present a case with presence of axillary lymph node metastases that was successfully treated with no evidence of recurrence one year after the diagnosis and review the literature. PMID:26712257

    Isolated spinal leptomeningeal metastases (LMM) without brain metastases are infrequent, accounting for about 1% of all solid tumors. In LMM, cerebrospinal fluid (CSF) analyses are mostly abnormal. Demonstrations of intrathecal tumor markers are highly suggestive, but only a positive cytology is diagnostic. The initial CSF cytology can give a false negative result in up to 40-50% of patients with pathologically proven LMM on autopsy. We report a case of intrahepatic cholangiocarcinoma with spinal LMM confirmed using cytokeratin7 and pancytokeratin (AE1/AE3) immunocytochemical studies on paucicellular cerebrospinal fluid cytospin preparation. Given the paucicellularity of the smears and difficult morphologic categorization, immunocytochemistry is vital for confirmatory diagnosis and can help reduce false negative results. To the best of our knowledge this is the first case report of cytologically confirmed LMM from an intrahepatic cholangiocarcinoma while the patient was undergoing treatment. PMID:23341095

    The current World Health Organization classification recognizes 3 subtypes of breast carcinomas with neuroendocrine features. Their reported prevalence is highly variable, ranging from <1% to up to 20% of all breast carcinomas. We report the case of a 73-year-old woman who underwent lumpectomy with a postoperative diagnosis of invasive ductal breast carcinoma. Six weeks after lumpectomy, pancreatic biopsies showed tumor cells with neuroendocrine features. The first immunohistochemical panel showed positivity for synaptophysin and cytokeratins, raising suspicion of a pancreatic neuroendocrine tumor. However, a second panel revealed positivity for estrogen receptors and GATA3. On review of the lumpectomy specimen, a significant neuroendocrine component was found, leading to the final diagnosis of breast carcinoma with neuroendocrine features metastasizing to the pancreas. Neuroendocrine markers are not routinely analyzed in breast tumors. Hence, metastases from breast carcinomas with unrecognized neuroendocrine features may lead to false diagnoses of primary neuroendocrine tumors at different metastatic sites, such as the pancreas.

    Pulmonary blastoma, a rare malignant lung tumour, can metastasise to the brain. However, there is no evidence for any effective treatment. The aim of this report is to discuss the treatment options for pulmonary blastoma and confirm the necessity for a pathological diagnosis. A 75-year-old man was admitted with progressive right-sided hemiplegia and aphasia. MRI showed multiple brain tumours. A left frontal lobe lesion was surgically resected, after which he underwent whole brain radiation (30 Gy/10 fractions). He died of an acute exacerbation of interstitial pneumonia. On performing autopsy, partial responses in the brain metastases that had been irradiated were confirmed pathologically. Thus, we present pathological confirmation that surgery and radiation therapy have therapeutic effects on brain metastases from pulmonary blastoma. PMID:24895392

    Hepatic metastases, which are frequently seen in patients with neuroendocrine tumors (NETs), have a major adverse impact on the patient's quality of life and survival. Surgery is the treatment of choice for hepatic metastases but is possible in only a small percentage of patients. Systemic chemotherapy yields disappointing results. Somatostatin analogs are effective in controlling symptoms in many of these patients; however, the disease can become refractory to treatment. Transcatheter intra-arterial liver-directed therapies, such as hepatic artery embolization, chemoembolization, and radioembolization are frequently used in patients with NETs metastatic to the liver, especially in patients with refractory, unresectable, or recurrent disease. These treatments are effective in palliating the hormonal symptoms as well as achieving objective tumor responses. This review focuses on the technique, safety, and clinical efficacy of hepatic artery embolization, chemoembolization, and radioembolization in patients with metastatic NETs. PMID:24436515

    Cutaneous metastases can have many different clinical presentations. They are seen in patients with advanced malignant disease; however, they can be the initial manifestation of undetected malignancies. Inflammatory breast carcinoma is a rare and aggressive form of breast cancer that has a nonspecific appearance mimicking many benign conditions including mastitis, breast abscesses, and/or dermatitis. The authors report the case of a 40-year-old woman with inflammatory breast carcinoma presenting with violaceous papulovesicular lesions resembling lymphangioma circumscriptum and erythematous patches resembling erysipelas. These lesions represent two different types of cutaneous metastases, both of which were the initial signs of inflammatory breast carcinoma in the patient described herein. Skin biopsy of lesions confirmed invasive breast cancer and further prompted a work up for inflammatory breast carcinoma. This case demonstrates the importance of follow-up for all breast lesions, even those considered to be of benign nature, for they can be presenting signs of metastatic breast cancer. PMID:26345728

    A 58-year-old female with a non-resectable ventricular cancer was followed by conventional 3.0 T magnetic resonance imaging (MRI) of the pelvis and abdomen including diffusion-weighted MR imaging (DWI). B-values were 0 and 1,000 seconds/mm2, and the apparent diffusion coefficient was calculated. At one control, ovarian metastases were detected by DWI, but did not show on conventional T2 and T1. The ovarian metastases were surgically removed and histologically verified - even though metastasectomy is controversial. In conclusion, DWI at 3.0 T is feasible and can improve the detection of metastatic disease compared with conventional MRI. PMID:21501566

    There are multiple clinical and histopathologic presentations of cutaneous metastases. We report 3 cases of visceral malignancies metastasizing to the skin and histopathologically mimicking interstitial granulomatous processes, including granuloma annulare and interstitial granulomatous dermatitis. Histopathologic examination of skin biopsy specimens, from our patients with established histories of cancer, revealed malignant carcinoma-derived cells organized in an interstitial pattern. Of note, some of the lesional cells appeared relatively bland without significant cellular atypia. When examining a skin biopsy of a new lesion from a patient with a history of internal malignancy, it is important to perform immunohistochemical staining to evaluate for metastatic disease, even if the histological pattern is suggestive of a benign interstitial granulomatous process.

    Despite advances in adjuvant therapy for breast cancer, bone remains the most common site of recurrence. The goal of therapy for these patients is palliative and focused on maximizing the duration and quality of their life, while concurrently minimizing any disease or treatment-related complications. Bone metastases predispose patients to reduced survival, pain, impaired quality of life and the development of skeletal-related events. With an increased understanding of the pathophysiology of bone metastasis, effective treatments for their management have evolved and are now in widespread clinical use. This article will discuss the pathogenesis of bone metastases and review the key clinical evidence for the efficacy and safety of currently available systemic bone-targeted therapies in breast cancer patients with an emphasis on bisphosphonates and the receptor activator of nuclear factor kappa B ligand (RANKL) inhibitors. We will also discuss novel strategies and therapies currently in development. PMID:26237063

    Neuroendocrine tumors (NETs) comprise a heterogeneous group of tumors that form a distinct entity. Approximately 75–80% of patients present with liver metastases at the time of their diagnosis, and 20%–25% will develop these lesions in the course of their disease. The presence of secondary deposits in the liver significantly increases the morbidity and mortality in these patients. The only potentially curative treatment is the surgical resection of the primary tumor and hepatic lesions. However, only 10% of patients presents under ideal conditions for that approach. Several techniques aimed at localized liver lesions have been applied also with interesting results in terms of survival and symptom control. The same has been demonstrated with new systemic therapies (target therapies). However, these are still under study, in order to define their true role in the management of these patients. This paper intends to address, in a general way, the various treatment options in patients with liver metastases from neuroendocrine tumors. PMID:27335831

    Background KRAS mutations in colorectal cancer primary tumors predict resistance to anti-Epidermal Growth Factor Receptor (EGFR) monoclonal antibody therapy in patients with metastatic colorectal cancer, and thus represent a true indicator of EGFR pathway activation status. Methodology/Principal Findings KRAS mutations were retrospectively studied using polymerase chain reactions and subsequent sequencing of codons 12 and 13 (exon 2) in 110 patients with metastatic colorectal tumors. These studies were performed using tissue samples from both the primary tumor and their related metastases (93 liver, 84%; 17 lung, 16%). All patients received adjuvant 5-Fluorouracil-based polychemotherapy after resection of metastases. None received anti-EGFR therapy. Mutations in KRAS were observed in 37 (34%) of primary tumors and in 40 (36%) of related metastases, yielding a 94% level of concordance (kappa index 0.86). Patients with primary tumors possessing KRAS mutations had a shorter disease-free survival period after metastasis resection (12.0 vs 18.0 months; P = 0.035) than those who did not. A higher percentage of KRAS mutations was detected in primary tumors of patiens with lung metastases than in patients with liver metastases (59% vs 32%; p = 0.054). To further evaluate this finding we analyzed 120 additional patients with unresectable metastatic colorectal cancer who previously had their primary tumors evaluated for KRAS mutational status for clinical purposes. Separately, the analysis of these 120 patients showed a tendency towards a higher degree of KRAS mutations in primary tumors of patients with lung metastases, although it did not reach statistical significance. Taken together the group of 230 patients showed that KRAS was mutated significantly more often in the primary tumors of patients with lung metastases (57% vs 35%; P = 0.006). Conclusions/Significance Our results suggest a role for KRAS mutations in the propensity of primary colorectal tumors to

    Widespread osteoblastic metastases, as well as marked elevations of CA19-9 and carcino-embryonic antigen (CEA), are the initial manifestations of gastric signet ring cell carcinoma. CT Imaging revealed diffuse sclerotic metastases in the axial skeleton. It was only following gastric biopsy that the primary site of metastatic bone tumor was identified. Recent studies suggest that early diagnosis of cancer origin, including tumor molecular profiling, may dictate specific therapy, improve prognosis and increase patient survival rates. PMID:27034800

    Promising results from new approaches such as radiosurgery or stereotactic radiosurgery of brain metastases have recently been reported. Are these results due to the therapy alone or can the results be attributed in part to patient selection? An analysis of tumor/patient characteristics and treatment variables in previous RTOG brain metastases studies was considered necessary to fully evaluate the benefit of these new interventions.

    A controlled clinical trial conducted by the European Organization for Research on Treatment of Cancer Radiotherapy Cooperative Group has shown that prophylactic lung irradiation is effective in preventing lung metastases in patients under 17 years of age. Recently, a new three-armed trial has started in which prophylactic chemotherapy and lung irradiation and chemotherapy combined with radiotherapy to the lungs will be compared for their ability to prevent the development of lung metastases.

  2. Prognostic factors for outcomes after whole-brain irradiation of brain metastases from relatively radioresistant tumors: a retrospective analysis

    2010-01-01

    Background This study investigated potential prognostic factors in patients treated with whole-brain irradiation (WBI) alone for brain metastases from relatively radioresistant tumors such as malignant melanoma, renal cell carcinoma, and colorectal cancer. Additionally, a potential benefit from escalating the radiation dose was investigated. Methods Data from 220 patients were retrospectively analyzed for overall survival and local control. Nine potential prognostic factors were evaluated: tumor type, WBI schedule, age, gender, Karnofsky performance score, number of brain metastases, extracerebral metastases, interval from diagnosis of cancer to WBI, and recursive partitioning analysis (RPA) class. Results Survival rates at 6 and 12 months were 32% and 19%, respectively. In the multivariate analysis, WBI doses >30 Gy (p = 0.038), KPS ≥70 (p < 0.001), only 1-3 brain metastases (p = 0.007), no extracerebral metastases (p < 0.001), and RPA class 1 (p < 0.001) were associated with improved survival. Local control rates at 6 and 12 months were 37% and 15%, respectively. In the multivariate analyses, KPS ≥70 (p < 0.001), only 1-3 brain metastases (p < 0.001), and RPA class 1 (p < 0.001) were associated with improved local control. In RPA class 3 patients, survival rates at 6 months were 10% (35 of 39 patients) after 10 × 3 Gy and 9% (2 of 23 patients) after greater doses, respectively (p = 0.98). Conclusions Improved outcomes were associated with WBI doses >30 Gy, better performance status, fewer brain metastases, lack of extracerebral metastases, and lower RPA class. Patients receiving WBI alone appear to benefit from WBI doses >30 Gy. However, such a benefit is limited to RPA class 1 or 2 patients. PMID:20977700

    Purpose Brain metastases of breast cancer cause neurocognitive damage and are incurable. We evaluated a role for temozolomide in the prevention of brain metastases of breast cancer in experimental brain metastasis models. Experimental Design Temozolomide was administered in mice following earlier injection of brain-tropic human epidermal growth factor receptor 2 (HER2)-positive Jimt1-BR3 and triple negative 231-BR-EGFP sublines, the latter with and without expression of 06-methylguanine-DNA methyltransferase (MGMT). Additionally, the percentage of MGMT-positive tumor cells in 62 patient-matched sets of breast cancer primary tumors and resected brain metastases was determined immunohistochemically. Results Temozolomide, when dosed at 50, 25, 10 or 5 mg/kg, 5 days/week, beginning 3 days after inoculation, completely prevented the formation of experimental brain metastases from MGMT-negative 231-BR-EGFP cells. At a 1 mg/kg dose, temozolomide prevented 68% of large brain metastases, and was ineffective at a dose of 0.5 mg/kg. When the 50 mg/kg dose was administered beginning on days 18 or 24, temozolomide efficacy was reduced or absent. Temozolomide was ineffective at preventing brain metastases in MGMT-transduced 231-BR-EGFP and MGMT-expressing Jimt-1-BR3 sublines. In 62 patient-matched sets of primary breast tumors and resected brain metastases, 43.5% of the specimens had concordant low MGMT expression, while in another 14.5% of sets high MGMT staining in the primary tumor corresponded with low staining in the brain metastasis. Conclusions Temozolomide profoundly prevented the outgrowth of experimental brain metastases of breast cancer in an MGMT-dependent manner. These data provide compelling rationale for investigating the preventive efficacy of temozolomide in a clinical setting. PMID:24634373

    Patients with endometrial endometrioid carcinoma (EEC) that present with advanced primary disease and develop recurrences have a poor outcome. The phenotype of EEC metastases and recurrences is poorly studied. We evaluated the morphological features and ER-alpha/PRA/p53 immunohistochemical expression of a sample of 45 EEC metastases compared to matched primary tumors. Additionally, we studied methylation levels of ER-alpha/PRA gene promoters. The distribution of histological FIGO grade was significantly different in metastases, which disclosed higher grade than primary tumors (p = 0.005). Mitotic index was significantly lower in metastases compared to matched primary tumors (p<0.001). ER-alpha (p = 0.002) and PRA (p<0.001) median H-scores were significantly lower in metastases than in matched primary EECs, but there was no significant difference concerning p53 expression (p = 0.056). ER-alpha/PRA expression differences did not correlate with differences in metastases morphology. ER-alpha/PRA gene promoter levels were globally low (range: 0% to 11.9%). One case showed higher ER-alpha gene promoter methylation in metastasis compared to matched EEC primary tumor. Regarding PRA, there was a significant higher frequency of its promotor methylation in metastases compared to primary tumors (51.6% vs. 22.7%, p = 0.022). In conclusion, EEC metastatic disease displays phenotypic changes along with ER-alpha and PRA decreased expression compared to primary tumors. ER-alpha and PRA gene promoter methylation seems to play a limited role in the etiology of these alterations. PR expression assessment for hormonal treatment decision of patients with advanced tumors, may be more adequate in metastases than in EEC primary tumors. PMID:26252518

    The aim of this study was to assess the characteristics of breast cancer patients with central nervous system (CNS) metastases and factors associated with survival after development of CNS metastasis. One-hundred-forty-four patients with brain metastases were retrospectively analyzed. Median age at the time of brain metastasis diagnosis was 48.9. Median time between initial diagnosis and development of brain metastasis was 36 months. Fourteen cases had leptomeningeal involvement. Twenty-two patients (15.3%) had single metastasis. Ten percent of the patients had surgery, 94% had radiotherapy and 63% had chemotherapy. Median survival after development of brain metastasis was 7.4 months. Survival of patients with single metastasis was significantly longer than those with multiple metastases (33.5 vs. 6.5 months, p = 0.0006). Survival of patients who received chemotherapy was significantly longer than those who received radiotherapy alone (9.9 vs. 2 months, p < 0.0001). In multivariate Cox regression analyses, presence of single metastasis and application of chemotherapy were the only significant factors associated with better survival (p = 0.047 and p < 0.0001, respectively). Age at initial diagnosis or at the time of brain metastasis, time from initial diagnosis to development of brain metastasis, menopausal status, tumor stage, grade, hormone receptor or HER2 status individually were not associated with survival. In this study, survival after the diagnosis of CNS metastases appeared to be affected by patient characteristics rather than biologic characteristics of the tumor. This is probably secondary to the lack of effective treatment options in these patients and overall poor prognosis. PMID:18507204

    This case series describes two patients with previously treated medulloblastoma who present with systemic metastases without evidence of central nervous system (CNS) disease. Patient #1 is male who presented at age 29 with pathology confirmed medulloblastoma treated with complete surgical resection followed by radiation (36 Gy craniospinal plus posterior fossa boost). Subsequently, he received cisplatin, cytoxan, and vincristine. One year later, he developed back pain and urinary retention. Imaging of his spine showed widespread bony metastases without parenchymal CNS disease. Biopsy of the left acetabulum confirmed metastatic medulloblastoma. He is currently enrolled on study with LDE225 versus temozolomide. Surveillance imaging to date is negative for intracranial metastasis, but does show extensive bony metastases involving the total spine, pelvis, ribs, sternum, clavicles, humeri, and femurs. Patient #2 is a female who presented at 32 years with severe headaches, nausea and vomiting found to have pathology confirmed medulloblastoma. She was lost to follow up temporarily, but presented again months later with headaches. She had a recurrent mass and underwent repeat resection. MRI of the spine showed nodular enhancement of the sacral nerve roots compatible with leptomeningeal spread. She underwent craniospinal radiation 36 Gy with a boost to the lumbar region and posterior fossa. One year after initial diagnosis, she presented with hypotension, tachycardia, and fatigue. Neuroimaging showed improved enhancement of the sacral nerve roots and brain imaging showed stable postsurgical changes. Systemic imaging, however, revealed widespread metastatic disease in the lymphatic system, liver, lung, and bones. The patient passed away a few months later. Medulloblastoma can metastasize outside the central nervous system (CNS), however typically does so concurrently with CNS progression. Here we present two adult patients with widely metastatic medulloblastoma systemically

    Purpose To investigate the relationship between LDH-A expression, lactate concentration, cell metabolism and metastases in murine 4T1 breast tumors. Experimental Design Inhibition of LDH-A expression and protein levels were achieved in a metastatic breast cancer cell line (4T1) using shRNA technology. The relationship between tumor LDH-A protein levels and lactate concentration (measured by magnetic resonance spectroscopic imaging-MRSI) and metastases was assessed. Results LDH-A knockdown cells (KD9) showed a significant reduction in LDH-A protein and LDH activity, less acid production, decreased transwell migration and invasion, lower proliferation, reduced glucose utilization and glycolysis and increase in oxygen consumption, ROS and cellular ATP levels, compared to control (NC) cells cultured in 25 mM glucose. In vivo studies showed lower lactate levels in KD9, KD5, KD317 tumors than in NC or 4T1 wild-type tumors (p<0.01), and a linear relationship between tumor LDH-A protein expression and lactate concentration. Metastases were delayed and primary tumor growth rate decreased. Conclusions We show for the first time that LDH-A knockdown inhibited the formation of metastases, and was accompanied by in vivo changes in tumor cell metabolism. Lactate MRSI can be used as a surrogate to monitor targeted inhibition of LDH-A in a pre-clinical setting and provides a non-invasive imaging strategy to monitor LDH-A targeted therapy. This imaging strategy can be translated to the clinic to identify and monitor patients who are at high risk of developing metastatic disease. PMID:23833310

    Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patients (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.

    The efficacy of radionuclide bone scans in monitoring metastatic bone activity remains controversial. Objective measurement of bone tumor burden would be useful for the evaluation of new therapies for metastatic carcinoma of the prostate. The recent discovery of the urinary excretion of pyridinoline (cross-link of mature collagen found in cartilage and bone) and deoxypyridinoline (collagen cross-link specific to bone) measured by high pressure liquid chromatography has provided sensitive specific indexes of cartilage and bone breakdown in rheumatoid arthritis, osteoporosis and metabolic bone diseases. We compared the urinary excretion of deoxypyridinoline,pyridinoline and hydroxyproline relative to urinary creatinine (nmol./mmol.creatinine) in 27 patients with benign prostatic hyperplasia (patient age 70.0 +/- 8.5 years, standard deviation), 29 with clinically confined prostate cancer (age 70.2 +/- 9.7 years), and 26 with prostate cancer and bone metastases (age 71.1 +/- 7.7 years). No diurnal variation of deoxypyridinoline or pyridinoline urinary excretion was detected in 5 patients with metastases. Urinary excretion of pyridinoline and deoxypyridinoline was significantly greater in patients with metastatic carcinoma of the prostate compared with patients with either benign prostatic hyperplasia (Mann-Whitney-Wilcoxon rank sum analysis, p < 0.00004 and 0.002, respectively) or localized prostate cancer (Mann-Whitney-Wilcoxon, p < 0.00001 and 0.00005, respectively). Urinary hydroxyproline levels failed to separate the 3 groups. Pyridinoline and deoxypyridinoline excretion in prostate cancer patients with metastases directly correlated with bone scan Soloway scores (r = 0.55, p < 0.005 and r = 0.57, p < 0.004 respectively), whereas serum prostate specific antigen did not (r = 0.36, p = 0.08). Serial measurements of pyridinoline and deoxypyridinoline progressively increased in 3 patients with clinical progression documented by new metastatic lesions by bone scan

    Purpose: We report the medium-term clinical outcome of hypofractionated stereotactic body radiotherapy (SBRT) in a series of patients with either a solitary metastasis or oligometastases from different tumors to abdominal lymph nodes. Methods and Materials: Between January 2006 and June 2009, 19 patients with unresectable nodal metastases in the abdominal retroperitoneal region were treated with SBRT. Of the patients, 11 had a solitary nodal metastasis and 8 had a dominant nodal lesion as part of oligometastatic disease, defined as up to five metastases. The dose prescription was 45 Gy to the clinical target volume in six fractions. The prescription had to be downscaled by 10% to 20% in 6 of 19 cases to keep within dose/volume constraints. The first 11 patients were treated with three-dimensional conformal techniques and the last 8 by volumetric intensity-modulated arc therapy. Median follow-up was 1 year. Results: Of 19 patients, 2 had a local progression at the site of SBRT; both also showed concomitant tumor growth at distant sites. The actuarial rate of freedom from local progression was 77.8% {+-} 13.9% at both 12 and 24 months. Eleven patients showed progressive local and/or distant disease at follow-up. The 12- and 24-month progression-free survival rates were 29.5% {+-} 13.4% and 19.7% {+-} 12.0%, respectively. The number of metastases (solitary vs. nonsolitary oligometastases) emerged as the only significant variable affecting progression-free survival (p < 0.0004). Both acute and chronic toxicities were minimal. Conclusions: Stereotactic body radiotherapy for metastases to abdominal lymph nodes was shown to be feasible with good clinical results in terms of medium-term local control and toxicity rates. Even if most patients eventually show progressive disease at other sites, local control achieved by SBRT may be potentially significant for preserving quality of life and delaying further chemotherapy.

    Purpose: Patients with brain metastases may experience treatment-related cognitive deficits. In this study, we prospectively assessed the self-reported cognitive abilities of patients with brain metastases from any solid primary cancer before and after irradiation of the brain. Methods and Materials: The treatment group (TG) consisted of adult patients (n=50) with brain metastases who received whole or partial irradiation of the brain without having received prior radiation therapy (RT). The control group (CG) consisted of breast cancer patients (n=27) without cranial involvement who were treated with adjuvant RT. Patients were recruited between May 2008 and December 2010. Self-reported cognitive abilities were acquired before RT and 6 weeks, 3 months, and 6 months after irradiation. The information regarding the neurocognitive status was collected by use of the German questionnaires for self-perceived deficits in attention (FEDA) and subjectively experienced everyday memory performance (FEAG). Results: The baseline data showed a high proportion of self-perceived neurocognitive deficits in both groups. A comparison between the TG and the CG regarding the course of self-reported outcomes after RT showed significant between-group differences for the FEDA scales 2 and 3: fatigue and retardation of daily living activities (P=.002) and decrease in motivation (P=.032) with an increase of attention deficits in the TG, but not in the CG. There was a trend towards significance in FEDA scale 1: distractibility and retardation of mental processes (P=.059) between the TG and the CG. The FEAG assessment presented no significant differences. An additional subgroup analysis within the TG was carried out. FEDA scale 3 showed significant differences in the time-related progress between patients with whole-brain RT and those receiving hypofractionated stereotactic RT (P=.025), with less decrease in motivation in the latter group. Conclusion: Self-reported attention declined in

    Purpose: Approximately 30% of patients with cancer receive bone metastases, of which 50% are in the spine. Approximately 20% present with unstable lesions requiring surgical intervention, followed by fractionated radiotherapy over 2-4 weeks to prevent early regrowth. Because of the limited survival time of patients with metastatic cancer, novel treatment concepts shortening the overall treatment time or hospitalization are desirable. In this study, we established a novel approach for intraoperative radiotherapy during kyphoplasty (Kypho-IORT), a method that combines stabilizing surgery and radiotherapy within one visit, after estimating the percentage of eligible patients for this treatment. Methods and Materials: To estimate the percentage of eligible patients, 53 planning CTs (897 vertebrae) of patients with spinal metastases were evaluated. The number of infiltrated vertebrae were counted and classified in groups eligible or not eligible for Kypho-IORT. The Kypho-IORT was performed in a donated body during a standard balloon kyphoplasty using the INTRABEAM system and specially designed applicators. A single dose of 10 Gy (in 10 mm) was delivered over 4 min to the vertebra. This was verified using two ionization chambers and a Monte Carlo simulation. Results: The estimation of eligible patients resulted in 34% of the evaluated patients, and thus 34% of patients with instable spinal metastases are suitable for Kypho-IORT. This study shows also that, using the approach presented here, it is possible to perform an IORT during kyphoplasty with an additional 15 min operation time. The measurement in the donated body resulted in a maximum dose of 3.8 Gy in the spinal cord. However, the Monte Carlo depth dose simulation in bone tissue showed 68% less dose to the prescription depth. Conclusion: We present for the first time a system using an x-ray source that can be used for single-dose IORT during kyphoplasty. The described Kypho-IORT can decrease the overall treatment

    Patient: Male, 67 Final Diagnosis: Gastric cancer with neuroendocrine carcinoma Symptoms: — Medication: — Clinical Procedure: Total gastrectomy • splenectomy with D2 lymph node dissection Specialty: Surgery Objective: Rare co-existance of disease or pathology Background: Many neuroendocrine carcinomas exhibit medullary infiltration and expanded proliferation. Differentiated tubular adenocarcinoma is frequently seen in the superficial region in many neuroendocrine carcinoma cases. However, the present case showed non-medullary infiltration and signet ring cell carcinoma in the superficial region, with intramural metastases distributed throughout the whole of the stomach. Case Report: A 67-year-old man was referred to our institution for treatment of gastric cancer. Type IIc-like advanced gastric cancer was detected in the greater curvature of the middle body of the stomach. The patient underwent total gastrectomy, splenectomy with D2 lymph node dissection, and Roux-en-Y reconstruction with curative resection. The tumor was diagnosed as a large-cell endocrine carcinoma of the stomach. A solid growth of signet ring cells was seen in the mucosa and submucosa. Intramural metastases were observed in many other depressed lesions. Large-cell carcinoma invaded the submucosa, mainly in the intramural metastatic site. Metastasis to one lesser curvature lymph node was also seen on histological examination. The final diagnosis was a gastric cancer of type 0–IIc (T4a) [M] (with intramural metastases) at T4aN1H0P0M0 Stage IIIA. This patient has remained alive without recurrence for 72 months after surgery. Conclusions: We recommend close preoperative examination of neuroendocrine carcinoma, taking intramural metastases into consideration. PMID:27102318

    We prospectively analyzed the safety and outcome of frameless image-guided robotic stereotactic radiosurgery (SRS) for treatment of brain metastases in patients that would have otherwise been treated with frame-based techniques. During a three-year period, 333 patients with 783 brain metastases of various histologies underwent 391 outpatient SRS procedures. Fifty-five percent of patients had multiple brain metastases. The median (mean) tumor volume was 1.0 cc (2.7 cc). The mean prescribed tumor dose was 18.5 Gy (+/-1.3 Gy). Local/distant tumor recurrences were treated by additional SRS for patients with stable systemic disease. Survival and freedom from local tumor recurrence was analyzed with the Kaplan-Meier method. Prognostic factors were obtained from the Cox proportional hazards model. System accuracy tests (end-to-end tests) were performed with a standard head phantom. Overall median survival was 12.2 months after SRS. The actuarial one-year local control rate was 95.2% (95% CI: 92.0-97.2); the distant brain tumor control rate was 67% (95% CI: 61.0-71.2). Most patients died from systemically progressing cancer (69%). A Karnofsky performance score (KPS) > 70 was related to prolonged survival in the univariate and multivariate analysis. Recursive partition analysis (RPA) classes I and II were related to prolonged survival in the univariate analysis. Twenty-one patients (6.3%) developed treatment-related neurotoxic effects; no patient died because of complications of SRS. Forty-five end-to-end tests documented a mean targeting accuracy of 0.48 +/- 0.22 mm. Single-session, frameless robotic SRS is feasible, accurate, and safe in selected patients with brain metastases of various primary tumors. There seems to be no difference in patient selection, adverse effects, treatment outcomes, or system accuracy compared with frame-based SRS. PMID:19802718

    Background c-MET plays an important role in tumor proliferation, invasion and metastasis. In this study we examined the expression of c-MET in colorectal adenomas, primary adenocarcinomas and their corresponding lymph node, peritoneal and liver metastases. We correlated our findings with clinicopathological features. Methods Twenty three cases of colorectal adenoma and 102 cases of primary colorectal carcinoma and their corresponding metastases (44 lymph nodes, 21 peritoneal deposits and 16 liver metastases) were studied to evaluate c-MET expression by immunohistochemistry. For comparison, 12 sections of adjacent healthy colorectal mucosa were examined. Results Statistically significant differences were present among normal tissues, colorectal adenomas and primary colorectal carcinomas (P=0.011). Normal tissues showed a negative or weak reaction in 66.67% and 33.33% of cases respectively. Expression of c-MET was positive in 47.8% of adenomas. A significant positive association was identified between c-MET high expression and degree of dysplasia (P=0.024). c-MET was highly expressed in 66.7% of primary colorectal carcinoma. Significant positive correlations were detected between c-MET expression and TNM stage (P=0.036), lymph node metastasis (LNM), peritoneal deposits and liver metastasis (P=0.038, P=0.094 and P=0.045, respectively). c-MET expression in metastatic tissues was significantly higher than that of the primary tumor. Conclusions c-MET expression is gradually up-regulated in the development and progression of colorectal cancer (CRC) from normal epithelium to adenoma to colorectal carcinoma to metastases.

    The development of novel therapies for breast cancer bone metastasis is a major unmet medical need. Toward that end, we have constructed an oncolytic adenovirus, Ad.dcn, and a nonreplicating adenovirus, Ad(E1-).dcn, both containing the human decorin gene. Our in vitro studies showed that Ad.dcn produced high levels of viral replication and the decorin protein in the breast tumor cells. Ad(E1-).dcn-mediated decorin expression in MDA-MB-231 cells downregulated the expression of Met, β-catenin, and vascular endothelial growth factor A, all of which are recognized decorin targets and play pivotal roles in the progression of breast tumor growth and metastasis. Adenoviral-mediated decorin expression inhibited cell migration and induced mitochondrial autophagy in MDA-MB-231 cells. Mice bearing MDA-MB-231-luc skeletal metastases were systemically administered with the viral vectors, and skeletal tumor growth was monitored over time. The results of bioluminescence imaging and X-ray radiography indicated that Ad.dcn and Ad(E1-).dcn significantly inhibited the progression of bone metastases. At the terminal time point, histomorphometric analysis, micro-computed tomography, and bone destruction biomarkers showed that Ad.dcn and Ad(E1-).dcn reduced tumor burden and inhibited bone destruction. A nonreplicating adenovirus Ad(E1-).luc expressing the luciferase 2 gene had no significant effect on inhibiting bone metastases, and in several assays, Ad.dcn and Ad(E1-).dcn were better than Ad.luc, a replicating virus expressing the luciferase 2 gene. Our data suggest that adenoviral replication coupled with decorin expression could produce effective antitumor responses in a MDA-MB-231 bone metastasis model of breast cancer. Thus, Ad.dcn could potentially be developed as a candidate gene therapy vector for treating breast cancer bone metastases. PMID:26467629

    The aim of this study was to assess the efficacy of percutaneous cementoplasty (PC) with polymethylmethacrylate (PMMA) in painful extravertebral lytic bone metastases not responding to conventional therapy. Fifty patients (25 females), mean age 64.7 {+-} 11.2 years, underwent PC after giving informed consent. Procedures were performed under fluoroscopy (1/50) or combined fluoroscopy-CT (49/50) guidance in local anesthesia or under deep sedation in 7 patients with large metastases who underwent radiofrequency thermoablation (RFA) in the same session. Seventy lesions were treated (1-6 per patient; average, 1.4 {+-} 0.9), arranging in size from 1 to 10 cm (average, 3.6 {+-} 2.1 cm). Mean volume of PMMA per lesion was 5.9 {+-} 3.2 ml (range, 1.5-15.0 ml). Pain was prospectively evaluated on an 11-point visual analog scale (VAS) before and after the procedure (follow-up, 15 to 36 months). Mean VAS score dropped from 9.1 {+-} 1.2 (range: 6-10) to 2.1 {+-} 2.5 (range: 0-9). Mean VAS difference was 7.0 {+-} 2.3 (range, 1-10; p < 0.0001, Wilcoxon signed rank test). Forty-seven of the 50 patients (94%) suspended narcotic drugs, in 22 (44%) pain was controlled with a nonsteroidal anti-inflammatory drug, in 25 (50%) analgesic therapy was suspended, and 13 of 50 (26%) had complete pain regression. In 3 of the 50 patients (6%) pain was not improved. No statistical difference between osteoplasty and osteoplasty plus RFA was found (p = 0.8338, Mann-Whitney test). No complications arose during the procedure. Two patients with metastases in the femoral diaphysis reported a fracture 1 month after treatment. PC is effective to obtain pain regression in painful bone metastases not responding to conventional analgesic therapy; bone consolidation cannot be obtained in the diaphysis of long weight-bearing bones.

    Purpose: Central nervous system (CNS) metastases are uncommon in patients with germ cell tumors, with an incidence of 2-3%. CNS metastases have been managed with whole brain radiotherapy (WBRT) and concomitant cisplatin-based combination chemotherapy. Our previous study did not observe serious CNS toxicity (Int J Radiat Oncol Biol Phys 1991;22:17-22). We now report on 5 patients who developed delayed significant CNS toxicity. Patients and Methods: We observed 5 patients with delayed CNS toxicity. The initial diagnosis was between 1981 and 2003. All patients had poor-risk disease according to the International Germ Cell Consensus Collaborative Group criteria. Of the 5 patients, 3 had CNS metastases at diagnosis and 2 developed relapses with CNS metastases. These 5 patients underwent WBRT to 4,000-5,000 cGy in 18-28 fractions concurrently with cisplatin-based chemotherapy. Results: All 5 patients developed delayed symptoms consistent with progressive multifocal leukoencephalopathy. The symptoms included seizures, hemiparesis, cranial neuropathy, headaches, blindness, dementia, and ataxia. The median time from WBRT to CNS symptoms was 72 months (range, 9-228). Head imaging revealed multiple abnormalities consistent with gliosis and diffuse cerebral atrophy. Of the 5 patients, 3 had progressive and 2 stable symptoms. Treatment with surgery and/or steroids had modest benefit. The progressive multifocal leukoencephalopathy resulted in significant debility in all 5 patients, resulting in death (3 patients), loss of work, steroid-induced morbidity, and recurrent hospitalizations. Conclusion: Whole brain radiotherapy is not innocuous in young patients with germ cell tumors and can cause late CNS toxicity.
