    The CLEOPATRA trial reported the survival benefit of pertuzumab with trastuzumab plus docetaxel in HER2-positive metastatic breast cancer patients. However, there are a few case reports concerning the effects of a pertuzumab-containing regimen on brain metastases. A 55-year-old woman, who underwent curative surgery for breast cancer after neoadjuvant chemotherapy 5 years previously, developed repeated solitary brain metastasis in her right occipital lobe. Whole brain radiation therapy, stereotactic radiosurgery and 3 times of surgical resection were performed. Lapatinib and capecitabine plus tamoxifen were administered. The metastasis recurred in the stump of the previous surgery. Pertuzumab with trastuzumab plus docetaxel was initiated as second-line chemotherapy. A complete response of the brain metastasis was achieved, which persisted for 5 months. Pertuzumab with trastuzumab plus docetaxel was effective in reducing the brain metastases from breast cancer. Further studies are warranted to confirm the effect of this regimen on brain metastases.

    Gastric cancer with brain metastasis is rare. The present study reports a case of gastric cancer with isolated brain metastasis 1 year after gastrectomy. To the best of our knowledge, there have been no prior reports of solitary brain metastasis from gastric cancer with peripheral nervous system symptoms. A distal gastrectomy was performed on a 60-year-old male patient with gastric cancer in November 2012. Postoperative pathological analysis revealed a moderately differentiated adenocarcinoma with tumor invasion into the serosa and metastasis to one dissected lymph node. No abnormalities were found at follow-up examination. However, a tumor representing metastasis to the brain was recognized by a cranial enhanced magnetic resonance imaging examination 1 year after gastrectomy, which was performed when the patient exhibited numbness and thigmesthesia. The patient was administered 30 Gy of stereotactic radiotherapy, delivered in 5 fractions. The patient succumbed to disease 10 months subsequent to undergoing radiotherapy. This case report suggests that gastric cancer may re-present as brain metastasis with peripheral nervous system symptoms. PMID:27073571

    We report a rare case of brain metastasis from papillary thyroid carcinoma with intracerebral hemorrhage. A 79-year-old woman presented with sudden headache and monoplegia of the right upper limb 10 years after diagnosis of thyroid papillary adenocarcinoma. Despite the known metastatic lesions in the cervical lymph nodes and lungs, she had been well for 10 years since thyroidectomy, focal irradiation and internal radiation of 131I. CT demonstrated intracerebral hemorrhage in the left temporal lobe. Magnetic resonance imaging showed marked signal heterogeneity. She underwent radical surgery on the day of the onset and the histological diagnosis was metastatic brain tumor of thyroid papillary carcinoma. Postoperative course was uneventful, and the monoplegia was improved. Papillary thyroid carcinoma has a relatively benign course, and surgical removal of the brain metastasis is able to contribute to longer survival times for patients.

    Tyrosine kinase inhibitors (TKIs) of epidermal growth factor receptor (EGFR) were previously the standard first-line treatments for lung cancers with activating EGFR mutations. The first-generation reversible EGFR TKIs, gefitinib and erlotinib, demonstrated substantial efficacy in the treatment of brain metastases from EGFR-mutated lung adenocarcinoma. However, the efficacy of afatinib, the second-generation irreversible EGFR TKI, as the first-line treatment in lung adenocarcinoma patients with brain metastasis has yet to be evaluated.Here, we report cases of 3 patients who received afatinib alone as the first-line treatment in combination with whole-brain radiotherapy or following surgical resection of brain metastases. All 3 patients had EGFR L858R mutation. The first patient had lung adenocarcinoma with brain metastasis and no neurologic symptoms. After consultation, she received afatinib as a first-line treatment. Chest computed tomography and brain magnetic resonance imaging (MRI) showed partial response. The second patient had lung adenocarcinoma accompanied with a metastatic brain lesion associated with seizures. This patient received whole-brain radiotherapy and afatinib treatment following brain MRI and subsequently showed significant regression of the brain metastasis. The third patient had strabismus of the right eye, and brain MRI showed a single tumor at the cerebellar pontine angle. This patient underwent surgical resection of the tumor followed by afatinib treatment. He refused adjuvant radiotherapy after surgery for brain metastasis. The brain MRI showed no recurrent brain metastasis, and the patient had relatively less neurologic deficiency.This series of 3 cases indicate that afatinib may be an appropriate first-line treatment alternative in patients having lung adenocarcinoma with EGFR mutations. Further retrospective analyses and prospective clinical trials are required to substantiate the efficacy of afatinib in the treatment of brain

    A case of cervical (C) spinal intramedullary metastasis and multiple small brain metastases from papillary thyroid carcinoma was presented. Spinal metastasis caused posterior neck and left shoulder pain, dysesthesia in both legs, and motor weakness in both legs and left arm, though the brain metastases were asymptomatic. Both the spinal and brain metastases were successfully treated by frameless stereotactic radiotherapy (SRT)/stereotactic radiosurgery (SRS). The patient's symptoms were almost entirely relieved within two months. A 76-year-old woman was diagnosed as having a thyroid tumor and lung metastasis by roentgenography and computed tomography. Biopsy of the thyroid tumor extending into the mediastinum revealed papillary thyroid carcinoma. She underwent surgical resection of thyroid with dissection of the mediastinum lymph node area. Internal oral radioisotope therapy was not effective for the multiple small lung metastases. She did well for 15 months, but later developed posterior neck and left shoulder pain and dysesthesia in the right leg and then dysesthesia and motor weakness in both legs. Then she experienced weakness in the left upper extremity. Magnetic resonance imaging (MRI) disclosed a small cervical spinal intramedullary mass lesion at the level of C6 and C7 on the left side as well as nine small brain lesions. The cervical spinal intramedullary metastatic tumor was treated by volumetric modulated arc radiotherapy (VMAT) SRT and the nine small brain metastatic tumors were treated by dynamic conformal arc (DCA) SRS uneventfully. A total dose of 39 Gy (100% dose) was delivered in 13 fractions for the spinal lesion (prescription, D95=95% dose; maximum dose=46.3 Gy). Single fraction SRS of 22 Gy (prescription, D95=100% dose) was performed for each of the nine small brain tumors. The spinal tumor was decreased in size on follow-up MRI two months after SRT. Three of the nine brain lesions had disappeared and six were decreased in size on

    We describe the case of a 67 years old man, that underwent orthotopic liver transplant (OLT) in 2004 for cirrhosis. Native liver hystological examination was negative for focal hepatocarcinoma (HCC) areas. In 2008, during regular follow up, pulmonary lesions were found and diagnosed as hepatocarcinoma metastasis.In 2013, patient accused vertigo and dizziness: neuroimaging showed a cerebellar lesion. Hystological diagnosis was HCC metastases. The peculiarity is the onset of lung metastasis after transplant, with negative analysis on native liver, and brain metastasis after stable disease. This case is also relevant due to long survival related to the unavailability of many oncologic therapies in transplanted patients.

    The majority of cutaneous squamous cell carcinoma (SCC) are diagnosed early and cured using local treatment, although a minority of cases metastasize to regional structures. In this report the authors describe an unknown feature of skin SCC, namely, distant brain metastasis. This 54-year-old man, who had undergone surgery for moderately differentiated SCC of the dorsum (T2NOM0 stage), was admitted to our institution 11 months later with headache, vomiting, and ataxia. A magnetic resonance image documented a cerebellar lesion, which was totally removed. Results of histological studies revealed SCC. The patient received whole-brain radiotherapy (30 Gy over 2 weeks using a linear accelerator). A metastatic work-up showed enlarged inguinal and para-aortic lymph nodes that were histologically examined using excisional biopsy. Inguinal lymph nodes were tumor-positive and were dissected. The patient was subjected to two cycles of chemotherapy with cisplatin (75 mg/m2). After 3 months, a significant reduction in the size of the para-aortic lymph nodes was documented on control computerized tomography studies. Although the described case is unique, knowledge of the potential for this uncommon behavior in cutaneous SCC may be useful, especially because of its increasing incidence.

    We report a case of brain metastasis from rectal cancer a long time after the initial resection. A 62-year-old woman, diagnosed with lower rectal cancer with multiple synchronous liver and lung metastases, underwent abdominoperineal resection after preoperative radiochemotherapy (40 Gy at the pelvis, using the de Gramont regimen FL therapy: 1 kur). The histological diagnosis was a moderately differentiated adenocarcinoma. Various regimens of chemotherapy for unresectable and metastatic colorectal cancer were administered, and a partial response was obtained; thereby, the metastatic lesions became resectable. The patient underwent partial resection of the liver and lung metastases. Pathological findings confirmed that both the liver and lung lesions were metastases from the rectal cancer. A disease-free period occurred for several months; however, there were recurrences of the lung metastases, so we started another round of chemotherapy. After 8 months, she complained of vertigo and dizziness. A left cerebellar tumor about 3 cm in diameter was revealed by MRI and neurosurgical excision was performed. Pathological findings confirmed a cerebellar metastasis from the rectal cancer. Twenty months after resection of the brain tumor, the patient complained of a severe headache. A brain MRI showed hydrocephalia, and carcinomatous meningitis from rectal cancer was diagnosed by a spinal fluid cytology test. A ventriculo-peritoneal shunt was inserted, but the cerebrospinal pressure did not decreased and she died 20 months after the first surgery. Although brain metastasis from colorectal cancer is rare, the number of patients with brain metastasis is thought to increase in the near future. Chemotherapy for colorectal cancer is effective enough to prolong the survival period even if multiple metastases have occurred. However, after a long survival period with lung metastases such as in our case, there is a high probability of developing brain metastases.

    Breast cancer, lung cancer and melanoma exhibit a high metastatic tropism to the brain. Development of brain metastases severely worsens the prognosis of cancer patients and constrains curative treatment options. Metastasizing to the brain by cancer cells can be dissected in consecutive processes including epithelial–mesenchymal transition, evasion from the primary tumor, intravasation and circulation in the blood, extravasation across the blood–brain barrier, formation of metastatic niches, and colonization in the brain. Ion channels have been demonstrated to be aberrantly expressed in tumor cells where they regulate neoplastic transformation, malignant progression or therapy resistance. Moreover, many ion channel modulators are FDA-approved drugs and in clinical use proposing ion channels as druggable targets for future anti-cancer therapy. The present review article aims to summarize the current knowledge on the function of ion channels in the different processes of brain metastasis. The data suggest that certain channel types involving voltage-gated sodium channels, ATP-release channels, ionotropic neurotransmitter receptors and gap junction-generating connexins interfere with distinct processes of brain metastazation.

    To review the existing literature on brain metastasis (BM) from ovarian cancer and to assess the frequency, anatomical, clinical and paraclinical information and factors associated with prognosis. Ovarian cancer is a rare cause of brain metastasis with a recently reported increasing prevalence. Progressive neurologic disability and poor prognosis is common. A comprehensive review on this subject has not been published previously. This systematic literature search used the Pubmed and Yale library. A total of 66 publications were found, 57 of which were used representing 591 patients with BM from ovarian cancer. The median age of the patients was 54.3 years (range 20-81). A majority of patients (57.3 %) had multiple brain lesions. The location of the lesion was cerebellar (30 %), frontal (20 %), parietal (18 %) and occipital (11 %). Extracranial metastasis was present in 49.8 % of cases involving liver (20.7 %), lung (20.4 %), lymph nodes (12.6 %), bones (6.6 %) and pelvic organs (4.3 %). The most common symptoms were weakness (16 %), seizures (11 %), altered mentality (11 %) visual disturbances (9 %) and dizziness (8 %). The interval from diagnosis of breast cancer to BM ranged from 0 to 133 months (median 24 months) and median survival was 8.2 months. Local radiation, surgical resection, stereotactic radiosurgery and medical therapy were used. Factors that significantly increased the survival were younger age at the time of ovarian cancer diagnosis and brain metastasis diagnosis, lower grade of the primary tumor, higher KPS score and multimodality treatment for the brain metastases. Ovarian cancer is a rare cause of brain metastasis. Development of brain metastasis among older patients and lower KPS score correlate with less favorable prognosis. The more prolonged survival after using multimodality treatment for brain metastasis is important due to potential impact on management of brain metastasis in future.

    Brain metastases represent the most common type of brain tumor. These tumors offer a dismal prognosis and significantly impact quality of life for patients. Their capacity for central nervous system (CNS) invasion is dependent upon induced disruptions to the blood-brain barrier (BBB), alterations to the brain microenvironment, and mechanisms for escaping CNS immunosurveillance. In the emerging era of immunotherapy, understanding how metastases are influenced by the immunologic peculiarities of the CNS will be crucial to forging therapeutic advances. In this review, the immunology of brain metastasis is explored. PMID:27622023

    Our understanding of the process of metastatic progression has improved markedly over the past decades, yet metastasis remains the most enigmatic component of cancer pathogenesis. This lack of knowledge has serious health-related implications, since metastasis is responsible for 90% of all cancer-related mortalities. The brain is considered a sanctuary site for metastatic tumor growth, where the blood–brain barrier (BBB) and other components of the brain microenvironment, provide protection to the tumor cells from immune surveillance, chemotherapeutics and other potentially harmful substances. The interactions between tumor cells and the brain microenvironment, principally brain vascular endothelium, are the critical determinants in their progression toward metastasis, dormancy, or clearance. This review discusses current knowledge of the biology of metastatic progression, with a particular focus on the tumor cell migration and colonization in the brain.

    Brain metastases occur in 20-40% of patients with advanced malignancies. A better understanding of the mechanism of this disease will help us to identify novel therapeutic strategies. In this review, we will discuss the systems biology approaches used in this area, including bioinformatics and mathematical modeling. Bioinformatics has been used for identifying the molecular mechanisms driving brain metastasis and mathematical modeling methods for analyzing dynamics of a system and predicting optimal therapeutic strategies. We will illustrate the strategies, procedures, and computational techniques used for studying systems biology in cancer brain metastases. We will give examples on how to use a systems biology approach to analyze a complex disease. Some of the approaches used to identify relevant networks, pathways, and possibly biomarkers in metastasis will be reviewed into details. Finally, certain challenges and possible future directions in this area will also be discussed.

    Purpose: Whole-brain radiation therapy (WBRT) is the standard of care after resection of a brain metastasis. However, concern regarding possible neurocognitive effects and the lack of survival benefit with this approach has led to the use of stereotactic radiosurgery (SRS) to the resection cavity in place of WBRT. We report our initial experience using an image-guided linear accelerator-based frameless stereotactic system and review the technical issues in applying this technique. Methods and Materials: We retrospectively reviewed the setup accuracy, treatment outcome, and patterns of failure of the first 18 consecutive cases treated at Brigham and Women's Hospital. The target volume was the resection cavity without a margin excluding the surgical track. Results: The median number of brain metastases per patient was 1 (range, 1-3). The median planning target volume was 3.49 mL. The median prescribed dose was 18 Gy (range, 15-18 Gy) with normalization ranging from 68% to 85%. In all cases, 99% of the planning target volume was covered by the prescribed dose. The median conformity index was 1.6 (range, 1.41-1.92). The SRS was delivered with submillimeter accuracy. At a median follow-up of 12.7 months, local control was achieved in 16/18 cavities treated. True local recurrence occurred in 2 patients. No marginal failures occurred. Distant recurrence occurred in 6/17 patients. Median time to any failure was 7.4 months. No Grade 3 or higher toxicity was recorded. A long interval between initial cancer diagnosis and the development of brain metastasis was the only factor that trended toward a significant association with the absence of recurrence (local or distant) (log-rank p = 0.097). Conclusions: Frameless stereotactic irradiation of the resection cavity after surgery for a brain metastasis is a safe and accurate technique that offers durable local control and defers the use of WBRT in select patients. This technique should be tested in larger prospective studies.

    The biology of breast cancer brain metastasis (BCBM) is poorly understood. We aimed to explore genes that are implicated in the process of brain metastasis of primary breast cancer (BC). NanoString nCounter Analysis covering 252 target genes was used for comparison of gene expression levels between 20 primary BCs that relapsed to brain and 41 BCBM samples. PAM50-based intrinsic subtypes such as HER2-enriched and basal-like were clearly over-represented in BCBM. A panel of 22 genes was found to be significantly differentially expressed between primary BC and BCBM. Five of these genes, CXCL12, MMP2, MMP11, VCAM1, and MME, which have previously been associated with tumor progression, angiogenesis, and metastasis, clearly discriminated between primary BC and BCBM. Notably, the five genes were significantly upregulated in primary BC compared to BCBM. Conversely, SOX2 and OLIG2 genes were upregulated in BCBM. These genes may participate in metastatic colonization but not in primary tumor development. Among patient-matched paired samples (n = 17), a PAM50 molecular subtype conversion was observed in eight cases (47.1%), with a trend toward unfavorable subtypes in patients with the distinct gene expression. Our findings, although not conclusive, reveal differentially expressed genes that might mediate the brain metastasis process. PMID:27340107

    Osteosarcomas are the most frequent primary malignant bone tumors in children and adolescents. Like brain metastases in osteosarcomas, the bowel metastases are very rare. We present the case of a 23-year-old female patient, diagnosed and operated in 2008 of osteosarcoma at the tibia, for which she had sessions of neoadjuvant and adjuvant chemotherapy, but presented lungs metastases for which she underwent surgery in 2014. Then, in March 2015, she was diagnosed with an intracranial expansive process, an osteosarcoma metastasis, for which a total ablation of the tumor was performed during the early postoperatory period, being transferred to the General Surgery Clinic for abdominal pain, abdominal distention, vomiting, and lack of intestinal transit regarding faeces and intestinal gas. Both clinically and imagistically, the diagnosis was of bowel obstruction. This was the reason for performing surgery, thus discovering a bowel obstruction secondary to a metastasis of the terminal ileum and liver metastases that were confirmed as osteosarcoma metastases from an anatomopathological and immunohistochemical point of view. The bowel metastases and the osteosarcoma brain metastases are very rare entities and, their association, most often with young patients, is exceptional. However, bowel metastases must be taken into account as a possible cause of bowel obstruction in patients with osteosarcoma. PMID:27452942

    Brain metastasis is a devastating complication of cancer with unmet therapeutic needs. The incidence of brain metastasis has been rising in cancer patients and its response to treatment is limited due to the singular characteristics of brain metastasis (i.e., blood-brain-barrier, immune system, stroma). Despite improvements in the treatment and control of extracranial disease, the outcomes of patients with brain metastasis remain dismal. The mechanisms that allow tumor cells to promulgate metastases to the brain remain poorly understood. Further work is required to identify the molecular alterations inherent to brain metastasis in order to identify novel therapeutic targets and explicate the mechanisms of resistance to systemic therapeutics. In this article, we review current knowledge of the unique characteristics of brain metastasis, implications in therapeutic resistance, and the possibility of developing biomarkers to rationally guide the use of targeted agents.

    Nongestational choriocarcinoma is very rare and carries a poor prognosis in female patients. In this report, the authors present a case of nongestational choriocarcinoma with brain metastasis in a female. A 58-year-old female with intermittent back pain was referred to a private hospital. On examination, a mediastinal tumor and a pancreatic tumor were detected. Endoscopic ultrasound-guided fine needle aspiration biopsy of the tumor was performed for histological evaluation. Pathological diagnosis was difficult because only a small amount of tissue was collected. Head MRI showed multiple metastatic tumors in the brain. The patient was diagnosed with primary mediastinal choriocarcinoma with brain metastasis. She was treated with one course of an etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine regimen, but her general condition gradually deteriorated, and she died on day 41. Nongestational choriocarcinoma is drug resistant, whereas gestational choriocarcinoma has better chemotherapeutic sensitivity. PMID:27172760

The patient was a 53-year-old male, already treated with total cystectomy and CAP therapy against pulmonary metastasis, which disappeared completely. At 8 months after complete remission of pulmonary metastasis, brain metastasis was found. One course of M-VAC therapy brought a complete remission persisting for 7 months.

    A 48-year-old woman underwent a total abdominal hysterectomy after preoperative diagnosis of multiple uterine leiomyomas. The histopathological diagnosis was leiomyosarcoma (LMS). After 47 months, multiple lung metastases were detected and resected. The patient was also diagnosed with pelvic bone metastasis and received six cycles of adjuvant chemotherapy with gemcitabine plus docetaxel and local radiation therapy to control the pain. Seventy-seven months from the initial diagnosis, she had a headache and developed left hemiparesis and aphasia. Imaging studies detected a solitary brain metastasis in the right frontal lobe. The patient underwent a craniotomy and resection of the lesion, which was a confirmed metastasis from uterine LMS by histopathology. One month after the craniotomy, the patient experienced lower abdominal pain, and a pelvic metastasis was detected. She was prescribed oral pazopanib (800 mg per day). For twelve months, she remained asymptomatic, but gradually, pelvic pain increased due to pelvic mass growth. After 14 months of pazopanib treatment, pazopanib was discontinued. To date, for 18 months after the brain surgery, she is alive with disease, and the brain metastasis has not recurred. PMID:27617285

    Pancreas is frequently site of isolated metastasis, approximately in the 40% of cases in patient with previous history of malignant neoplasia, more frequently from renal cell carcinoma. The melanoma metastasis can also interest the pancreas in case of disseminated disease (50% of the cases); more rarely the pancreas is site of isolated metastases from melanoma. The treatment of the pancreatic metastases from melanoma is controversial: the therapeutic choices are few and the role of surgery is not well defined. If the metastasis are confined to the pancreas, the surgical treatment can be useful for better long time survival. We report a rare case of melanoma with pancreatic isolated metastasi in a patient with a previous melanotic metastasis to the inguinal lymph nodes without evidence of primitive tumor.

    Introduction: Adrenocortical carcinoma (ACC) is a heterogeneous and rare disease. At presentation or at the time of a recurrence, the disease commonly spreads to the liver, lungs, lymph nodes, and bones. The brain has only rarely been reported as a site of metastases. Objective: The aims of this report were to describe the clinical characteristics of patients with ACC who developed brain metastasis and were evaluated at the National Cancer Institute. Methods: We describe the history and clinical presentation of six patients with ACC and metastatic disease in the brain. Images of the six patients and pathology slides were reviewed when available. Results: The median age at the time of the diagnosis of ACC was 42 years. The median time from the initial diagnosis until the presentation of brain metastasis was 43 months. As a group the patients had previously received multiples lines of chemotherapy (median of three), and they presented with one to three metastatic brain lesions. Four patients underwent metastasectomy, one had radiosurgery, and one had both modalities. Two patients are still alive, three died, between 2 and 14 months after the diagnosis of brain metastases, and one was lost to follow-up. Conclusion: Patients with advanced ACC can rarely present with metastasis to the brain, most often long after the initial diagnosis. Timely diagnosis of brain metastasis with appropriate intervention after discussion in a multidisciplinary meeting can improve the prognosis in this particular scenario. PMID:25412413

    Background: Mucoepidermoid carcinoma (MEC) is a rare tumor of the lung that accounts for 0.1–0.2% of all pulmonary tumors. To the best of our knowledge, brain metastasis from lung MEC is rare and magnetic resonance imaging (MRI) findings of this lesion have not been documented. Case Description: We herein report the case of a 72-year-old male. MRI revealed a left parietal tumor showing ring enhancement with medium gadolinium contrast and an evident high intensity area in the nonenhanced central portion on diffusion-weighted images (DWI) mimicking a brain abscess. Histologically, MEC is composed of a mixture of different cell types including mucin-secreting glandular cells and squamous cells. Accordingly, we suggest that the high DWI signal can be explained by the development of intracellular and intraluminal mucin, which have a high viscosity. Conclusion: Further accumulation of cases with brain metastasis from MEC is needed to establish the characteristic image findings, which would lead to prompt and adequate treatment. PMID:26167374

    More than 90% of cancer death is attributed to metastatic disease, and the brain is one of the major metastatic sites of melanoma, colon, renal, lung and breast cancers. Despite the recent advancement of targeted therapy for cancer, the incidence of brain metastasis is increasing. One reason is that most therapeutic drugs can't penetrate blood-brain-barrier and tumor cells find the brain as sanctuary site. In this review, we describe the pathophysiology of brain metastases to introduce the latest understandings of metastatic brain malignancies. This review also particularly focuses on non-coding RNAs and their roles in cancer brain metastasis. Furthermore, we discuss the roles of the extracellular vesicles as they are known to transport information between cells to initiate cancer cell-microenvironment communication. The potential clinical translation of non-coding RNAs as a tool for diagnosis and for treatment is also discussed in this review. At the end, the computational aspects of non-coding RNA detection, the sequence and structure calculation and epigenetic regulation of non-coding RNA in brain metastasis are discussed.

    Tumors metastasizing from distant regions to the oral and maxillofacial region are uncommon, comprising only 1%-2% of all malignancies. Cholangiocarcinoma is a malignancy that arises from cholangiocytes, which are epithelial cells that line the bile ducts. These cancers are difficult to diagnose and have a poor prognosis. In this paper, we report a rare case of mandibular metastasis of cholangiocarcinoma diagnosed at the primary site and discuss the radiographic findings observed in this case. PMID:26730373

    Lung cancer is a clinically difficult disease with rising disease burden around the world. Unfortunately, most lung cancers present at a clinically advanced stage. Of these cancers, many also present with brain metastasis which complicates the clinical picture. This review summarizes current knowledge on the molecular basis of lung cancer brain metastases. We start from the clinical perspective, aiming to provide a clinical context for a significant problem that requires much deeper scientific investigation. We review new research governing the metastatic process, including tumor cell signaling, establishment of a receptive tumor niches in the brain and evaluate potential new therapeutic options that take advantage of these new scientific advances. Lung cancer remains the largest single cause of cancer mortality in the United States (Siegel et al., 2015). This continues to be the clinical picture despite significant advances in therapy, including the advent of targeted molecular therapies and newly adopted immunotherapies for certain subtypes of lung cancer. In the vast majority of cases, lung cancer presents as advanced disease; in many instances, this advanced disease state is intimately associated with micro and macrometastatic disease (Goldberg et al., 2015). For both non-small cell lung cancer and small cell lung cancer patients, the predominant metastatic site is the brain, with up to 68% of patients with mediastinal lymph node metastasis eventually demonstrating brain metastasis (Wang et al., 2009).The frequency (incidence) of brain metastasis is highest in lung cancers, relative to other common epithelial malignancies (Schouten et al., 2002). Other studies have attempted to predict the risk of brain metastasis in the setting of previously non-metastatic disease. One of the largest studies to do this, analyzing historical data from 1973 to 2011 using the SEER database revealed a 9% risk of patients with previously non-metastatic NSCLC developing brain

    The purpose of this report was to review the role of whole brain radiotherapy (WBRT) in the management of brain metastases. In particular, we review the role of WBRT as a prophylactic therapy, and the role of surgery and stereotactic radiousurgery (SRS) with respect to WBRT, by discussing the relevant randomized controlled trials. WBRT is associated with toxicities and this may influence the decision to use WBRT and, therefore, we review both the acute side effects of WBRT and the more serious late side effects of neurocognitive impairment and leukoencephalopathy. As patients are living longer with brain metastases the role of WBRT is moving forward; however, using modern radiation technology we may be able to reduce the morbidity of this therapy. We present an extreme case of re-re-treatment WBRT with hippocampal sparing and simultaneous integrated boosts to multiple lesions as one of the future directions under evaluation. PMID:22236670

    Fully regressive melanoma is a phenomenon in which the primary cutaneous melanoma becomes completely replaced by fibrotic components as a result of host immune response. Although 10 to 35 percent of cases of cutaneous melanomas may partially regress, fully regressive melanoma is very rare; only 47 cases have been reported in the literature to date. AH of the cases of fully regressive melanoma reported in the literature were diagnosed in conjunction with metastasis on a patient. The authors describe a case of fully regressive melanoma without any metastases at the time of its diagnosis. Characteristic findings on dermoscopy, as well as the absence of melanoma on final biopsy, confirmed the diagnosis. PMID:27672418

    Glioblastoma multiforme is the most common primary malignant brain tumor. The clinical outcome following diagnosis remains extremely poor. The treatment of choice is wide surgical resection of the visible tumor, frequently followed by adjuvant combined radiochemotherapy (RCTx) with temozolomide as the chemotherapeutic agent. Extracranial metastases are extremely rare, with <200 cases of extracranial metastases from glioblastoma multiforme reported in the literature to date. We herein present a case of a patient suffering from a fast-growing metastasis to the oral cavity, completely filling the buccal cavity within 2 weeks, as the only manifestation of recurrent glioblastoma multiforme following initial surgical resection and adjuvant RCTx.

    The development of brain metastases in patients with advanced stage melanoma is common, but the molecular mechanisms responsible for their development are poorly understood. Melanoma brain metastases cause significant morbidity and mortality and confer a poor prognosis; traditional therapies including whole brain radiation, stereotactic radiotherapy, or chemotherapy yield only modest increases in overall survival (OS) for these patients. While recently approved therapies have significantly improved OS in melanoma patients, only a small number of studies have investigated their efficacy in patients with brain metastases. Preliminary data suggest that some responses have been observed in intracranial lesions, which has sparked new clinical trials designed to evaluate the efficacy in melanoma patients with brain metastases. Simultaneously, recent advances in our understanding of the mechanisms of melanoma cell dissemination to the brain have revealed novel and potentially therapeutic targets. In this review, we provide an overview of newly discovered mechanisms of melanoma spread to the brain, discuss preclinical models that are being used to further our understanding of this deadly disease and provide an update of the current clinical trials for melanoma patients with brain metastases.

    We report a case of pregnancy-associated breast cancer with metastasis to the brain, likely resulting from hereditary breast and ovarian cancer (HBOC). A 35-year-old woman (gravida 2, para 0-1-0-1) underwent a right mastectomy and right axillary dissection after a cesarean section at 30 years of age; her mother died at 47 years of age due to breast cancer. Histopathological examination indicated an invasive ductal carcinoma with triple-negative cancer (cancer stage 2B [pT3N0M0]). The patient refused adjuvant therapy because of the risk of infertility. After 4 years, she became pregnant naturally. At 18 weeks' gestation, she experienced aphasia and dyslexia due to brain metastasis. The pregnancy was terminated at 21 weeks' gestation after thorough counseling. Her family history, young-onset disease, and histopathological findings suggested HBOC. She declined genetic testing for BRCA1/2, though genetic counseling was provided. In cases of pregnancy-related breast cancer, consideration must be given to whether the pregnancy should be continued and to posttreatment fertility. HBOC should also be considered. Genetic counseling should be provided and the patient should be checked for the BRCA mutation, as it is meaningful for the future of any potential children. Genetic counseling should be provided even if the cancer is advanced or recurrent. PMID:26981296

    Resonant Raman (RR) spectroscopy provides an effective way to enhance Raman signal from particular bonds associated with key molecules due to changes on a molecular level. In this study, RR is used for detection of human brain metastases of five kinds of primary organs of lung, breast, kidney, rectal and orbital in ex-vivo. The RR spectra of brain metastases cancerous tissues were measured and compared with those of normal brain tissues and the corresponding primary cancer tissues. The differences of five types of brain metastases tissues in key bio-components of carotene, tryptophan, lactate, alanine and methyl/methylene group were investigated. The SVM-KNN classifier was used to categorize a set of RR spectra data of brain metastasis of lung cancerous tissues from normal brain tissue, yielding diagnostic sensitivity and specificity at 100% and 75%, respectively. The RR spectroscopy may provide new moleculebased optical probe tools for diagnosis and classification of brain metastatic of cancers.

    The brain is a common site of metastatic disease in patients with breast cancer, which has few therapeutic options and dismal outcomes. The purpose of our study was to identify common and rare events that underlie breast cancer brain metastasis. We performed deep genomic profiling, which integrated gene copy number, gene expression and DNA methylation datasets on a collection of breast brain metastases. We identified frequent large chromosomal gains in 1q, 5p, 8q, 11q, and 20q and frequent broad-level deletions involving 8p, 17p, 21p and Xq. Frequently amplified and overexpressed genes included ATAD2, BRAF, DERL1, DNMTRB and NEK2A. The ATM, CRYAB and HSPB2 genes were commonly deleted and underexpressed. Knowledge mining revealed enrichment in cell cycle and G2/M transition pathways, which contained AURKA, AURKB and FOXM1. Using the PAM50 breast cancer intrinsic classifier, Luminal B, Her2+/ER negative, and basal-like tumors were identified as the most commonly represented breast cancer subtypes in our brain metastasis cohort. While overall methylation levels were increased in breast cancer brain metastasis, basal-like brain metastases were associated with significantly lower levels of methylation. Integrating DNA methylation data with gene expression revealed defects in cell migration and adhesion due to hypermethylation and downregulation of PENK, EDN3, and ITGAM. Hypomethylation and upregulation of KRT8 likely affects adhesion and permeability. Genomic and epigenomic profiling of breast brain metastasis has provided insight into the somatic events underlying this disease, which have potential in forming the basis of future therapeutic strategies.

    Background Brain metastases from esophageal carcinoma have historically been rare and associated with poor prognosis. With improvements in systemic disease control, the incidence of brain metastases is expected to rise. To better inform management decisions, we sought to identify factors associated with survival in patients with brain metastasis from esophageal cancer. Methods We retrospectively identified 49 patients with brain metastasis from stage I–IV primary esophageal cancer treated with surgery, radiation, or a combination of modalities at our tertiary referral center between 1998 and 2015. Medical records were reviewed to collect demographic and clinical information. Results Median age at diagnosis of the primary esophageal cancer was 60 years. Forty-one (84%) patients were male and forty patients (82%) had adenocarcinoma. Median overall survival (MS) following esophageal cancer diagnosis was 24 months (range, 3–71 months), and median survival after the identification of brain metastases was 5 months (range, 1–52 months). On univariate analysis, only patients with poor Karnofsky performance status (KPS <70), recursive partitioning analysis (RPA) classification (III), or 3 or more brain metastases were found to have worsened survival after the diagnosis of brain metastases (all P<0.01). Factors not associated with survival were age, gender, histology (adenocarcinoma vs. other), palliative-intent treatment of the primary tumor, time to diagnosis of brain metastases from initial diagnosis, uncontrolled primary tumor at time of brain metastasis diagnosis, or extracranial metastases. On multivariate analysis (MVA, KPS excluded), patients with RPA class I (MS, 14.6 months) or II (MS, 5.0 months) disease had significantly improved overall survival compared to class III disease (MS, 1.6 months, P<0.01). Also on MVA, patients with 1 (MS, 10.7 months) or 2 (MS, 4.7 months) brain metastases had significantly improved overall survival compared to patients with 3

    Brain metastasis is a major challenge for patients, physicians, and the broader health care system, with approximately 170,000 new cases per year. After a diagnosis of brain metastasis, patients have a poor prognosis, but modern management has made significant advances in the past two decades to improve palliative efficacy and patient survival through a multidisciplinary approach. A number of factors must be taken into consideration in the treatment approach, including the number of intracranial lesions, the control of extracranial disease, and the patient's overall health, while weighing the benefits of treatment against the toxicities, both acute and chronic. With quality of life as an emphasis, emerging concepts for modern management of brain metastasis have sought to minimize long-term toxicities. The economic impact of such strategies for patients and the health care system has been demonstrated in some studies, but has not been a consistent area of focus. Each of these strategies, as well as novel therapeutics, has embraced the concept of personalized treatment. This review will discuss the current knowledge of modern multidisciplinary management of brain metastasis and look forward to emerging concepts.

    Herein, we report a rare case of malignant melanoma metastasis to the mammary gland. A 76-year-old woman had a tumor resection performed for primary malignant melanoma of the epipharynx. The patient subsequently underwent local and lymph node recurrence, for which she received heavy ion radiotherapy and lymph node dissection, respectively. The patient was referred to our hospital for a problem with her right breast. Computed tomography and magnetic resonance imaging showed a mammary tumor and multiple subcutaneous tumors. A biopsy was performed, which proved positive for S100 and Melan A staining, and the diagnosis of malignant melanoma was confirmed. Partial mastectomy was performed; and S100, HMB45, and Melan A positivity was confirmed based on immunohistological findings. The diagnosis was malignant melanoma metastasis to the mammary gland. Malignant melanoma commonly metastasizes to the liver, mediastinum, mediastinal glands, lung, and brain; and metastasis to the mammary gland is rare. To our knowledge, only 2 cases have previously been reported in the Japanese literature.

    Secondary tumours in the brain account for 40 % of triple negative breast cancer patients, and the percentage may be higher at the time of autopsy. The use of in vivo models allow us to recapitulate the molecular mechanisms potentially used by circulating breast tumour cells to proliferate within the brain.Metastasis is a multistep process that depends on the success of several stages including cell evasion from the primary tumour, distribution and survival within the blood stream and cerebral microvasculature, penetration of the blood-brain barrier and proliferation within the brain microenvironment. Cellular adhesion molecules are key proteins involved in all of the steps in the metastatic process. Our group has developed two different in vivo models to encompass both seeding and colonisation stages of the metastatic process: (1) haematogenous dissemination of tumour cells by direct injection into the left ventricle of the heart, and (2) direct implantation of the tumour cells into the mouse brain.This chapter describes, in detail, the practical implementation of the intracerebral model, which can be used to analyse tumour proliferation within a specific area of the central nervous system and tumour-host cell interactions. We also describe the use of immunohistochemistry techniques to identify, at the molecular scale, tumour-host cell interactions, which may open new windows for brain metastasis therapy.

    Breast cancer occurs in approximately 1 in 8 women and 1 in 37 women with breast cancer succumbed to the disease. Over the past decades, new diagnostic tools and treatments have substantially improved the prognosis of women with local diseases. However, women with metastatic disease still have a dismal prognosis without effective treatments. Among different molecular subtypes of breast cancer, the HER2-enriched and basal-like subtypes typically have higher rates of metastasis to the brain. Basal-like metastatic breast tumors frequently express EGFR. Consequently, HER2- and EGFR-targeted therapies are being used in the clinic and/or evaluated in clinical trials for treating breast cancer patients with brain metastases. In this review, we will first provide an overview of the HER2 and EGFR signaling pathways. The roles that EGFR and HER2 play in breast cancer metastasis to the brain will then be discussed. Finally, we will summarize the preclinical and clinical effects of EGFR- and HER2-targeted therapies on breast cancer metastasis.

    Purpose: To compare the outcome of surgical resection followed by whole brain radiotherapy (WBRT) with WBRT alone in patients treated for single brain metastasis. Methods and Materials: The data from 195 patients with single brain metastases were retrospectively evaluated. Of the 195 patients, 99 underwent resection of the metastasis followed by WBRT and 96 underwent WBRT alone. Seven additional potential prognostic factors were investigated: age, gender, Eastern Cooperative Oncology Group performance score, tumor type, interval between initial tumor diagnosis and WBRT, extracranial metastases, and recursive partitioning analysis class. Both treatment groups were well balanced for these factors. Results: On multivariate analysis, improved survival was associated with resection (relative risk [RR], 1.20; 95% confidence interval [CI], 1.11-1.31; p < 0.001), lower recursive partitioning analysis class (RR, 1.58; 95% CI, 1.22-2.06; p < 0.001), age {<=}61 years (RR, 1.79; 95% CI, 1.23-2.61; p = 0.002), Eastern Cooperative Oncology Group performance score of 0-1 (RR, 2.47; 95% CI, 1.70-3.59; p < 0.001), and the absence of extracranial metastases (RR, 1.99; 95% CI, 1.41-2.79; p < 0.001). Improved local control was associated with resection (RR, 1.25; 95% CI, 1.11-1.41; p < 0.001) and age {<=}61 years (RR, 1.77; 95% CI, 1.09-2.88; p = 0.020). Improved brain control distant from the original site was associated with lower recursive partitioning analysis class (RR, 1.65; 95% CI, 1.03-2.69; p < 0.035), age {<=}61 years (RR, 1.81; 95% CI, 1.12-2.96; p = 0.016), and the absence of extracranial metastases (RR, 2.42; 95% CI, 1.52-3.88; p < 0.001). Improved control within the entire brain was associated with surgery (RR, 1.24; 95% CI, 1.12-1.38; p < 0.001) and age {<=}61 years (RR, 1.83; 95% CI, 1.21-2.77; p = 0.004).

    Brain metastasis is one of the most important life-threatening conditions in patients with metastatic HER-2 positive breast cancer. A lot of conventional chemotherapeutic and antibody-based regimens used routinely in treatment of the patients with breast cancer are not effective due to blood-brain barrier. In our cases, we reported on three HER-2 positive breast cancer patients with brain metastasis who were offered a combination of weekly trastuzumab plus vinorelbine after brain metastasis. In our cases, the progression-free survival were 12, 16 and 9 months for Case 1, Case 2 and Case 3, respectively. In Case 1, there was no progression in the brain. In Case 3, we did not detect any progress but the patient died due to cerebrovascular embolic events. After local treatment, the combination of weekly trastuzumab plus vinorelbine may be an effective alternative regimen in HER-2 positive breast cancer patients with brain metastases.

    The present study reports a case of medullary metastasis without lung metastasis that occurred as a result of a malignant peripheral nerve sheath tumor (MPNST). An 81-year-old woman presented with a MPNST in the left brachial plexus, arising from the cervical nerve root. The patient underwent carbon ion radiotherapy; however, tumor recurrence was identified in the left shoulder. Subsequently, the patient underwent wide excision. Three weeks subsequent to surgery, imbalance and dysarthria developed suddenly. Dysphagia emerged and left upper limb pain disappeared on the day after symptom development. Magnetic resonance imaging (MRI) revealed that this was due to metastasis to the medulla. Five days subsequent to the onset of dysarthria, the patient succumbed due to respiratory failure. To the best of our knowledge, no previous cases of medullary metastasis arising from a MPNST in the absence of lung metastasis have been reported. MRI is a useful examination tool for the identification of brain metastases; however, the high cost of MRI as a routine examination must be considered due to the rarity of brain metastases. Therefore, methods to detect brain metastasis warrant further investigation. PMID:27588138

    Brain metastases (BMs) are the most common brain tumor in adults, developing in about 10% of adult cancer patients. It is not the incidence of BM that is alarming, but the poor patient prognosis. Even with aggressive treatments, median patient survival is only months. Despite the high rate of BM-associated mortality, very little research is conducted in this area. Lack of research and staggeringly low patient survival is indicative that a novel approach to BMs and their treatment is needed. The ability of a small subset of primary tumor cells to produce macrometastases is reminiscent of brain tumor-initiating cells (BTICs) or cancer stem cells (CSCs) hypothesized to form primary brain tumors. BTICs are considered stem cell-like due to their self-renewal and differentiation properties. Similar to the subset of cells forming metastases, BTICs are most often a rare subpopulation. Based on the functional definition of a TIC, cells capable of forming a BM could be considered to be brain metastasis-initiating cells (BMICs). These putative BMICs would not only have the ability to initiate tumor growth in a secondary niche, but also the machinery to escape the primary tumor, migrate through the circulation, and invade the neural niche.

    Brain metastases (BMs) are the most common brain tumor in adults, developing in about 10% of adult cancer patients. It is not the incidence of BM that is alarming, but the poor patient prognosis. Even with aggressive treatments, median patient survival is only months. Despite the high rate of BM-associated mortality, very little research is conducted in this area. Lack of research and staggeringly low patient survival is indicative that a novel approach to BMs and their treatment is needed. The ability of a small subset of primary tumor cells to produce macrometastases is reminiscent of brain tumor-initiating cells (BTICs) or cancer stem cells (CSCs) hypothesized to form primary brain tumors. BTICs are considered stem cell-like due to their self-renewal and differentiation properties. Similar to the subset of cells forming metastases, BTICs are most often a rare subpopulation. Based on the functional definition of a TIC, cells capable of forming a BM could be considered to be brain metastasis-initiating cells (BMICs). These putative BMICs would not only have the ability to initiate tumor growth in a secondary niche, but also the machinery to escape the primary tumor, migrate through the circulation, and invade the neural niche.

    Brain is one of the major sites of metastasis in breast cancer; however, the pathological mechanism of brain metastasis is poorly understood. One of the critical rate-limiting steps of brain metastasis is the breaching of blood-brain barrier, which acts as a selective interface between the circulation and the central nervous system, and this process is considered to involve tumor-secreted proteinases. We analyzed clinical significance of 21 matrix metalloproteinases on brain metastasis-free survival of breast cancer followed by verification in brain metastatic cell lines and found that only matrix metalloproteinase 1 (MMP1) is significantly correlated with brain metastasis. We have shown that MMP1 is highly expressed in brain metastatic cells and is capable of degrading Claudin and Occludin but not Zo-1, which are key components of blood-brain barrier. Knockdown of MMP1 in brain metastatic cells significantly suppressed their ability of brain metastasis in vivo, whereas ectopic expression of MMP1 significantly increased the brain metastatic ability of the cells that are not brain metastatic. We also found that COX2 was highly up-regulated in brain metastatic cells and that COX2-induced prostaglandins were directly able to promote the expression of MMP1 followed by augmenting brain metastasis. Furthermore, we found that COX2 and prostaglandin were able to activate astrocytes to release chemokine (C-C motif) ligand 7 (CCL7), which in turn promoted self-renewal of tumor-initiating cells in the brain and that knockdown of COX2 significantly reduced the brain metastatic ability of tumor cells. Our results suggest the COX2-MMP1/CCL7 axis as a novel therapeutic target for brain metastasis.

    Metastatic choroid melanoma is a highly malignant disease with a limited life expectancy. The liver is the most common site for metastasis of uveal melanoma followed by lung, bone, skin, and subcutaneous tissue. Metastasis from choroidal melanoma usually occurs within the first five years of treatment for primary tumours. Metastatic choroid melanoma to the spine/vertebrae is extremely rare. We report the first case of spinal metastasis from choroid melanoma in a 61-year-old man who had been treated for primary ocular melanoma three years earlier with radioactive plaque brachytherapy. Synchronously, at the time of metastasis, he was also diagnosed as having a new primary lung adenocarcinoma as well. The only other case reported on vertebral metastasis from malignant melanoma of choroid in literature in which primary choroid melanoma was enucleated. PMID:26989537

    Although various prognostic indices exist for patients with malignant brain tumors, the prognostic significance of the subependymal spread of intracranial tumors is still a matter of debate. In this paper, we report the cases of two intraventricular lesions, a recurrent glioblastoma multiforme (GBM) and a brain metastasis, each successfully treated with a neuroendoscopic approach. Thanks to this minimally invasive approach, we achieved good therapeutic results: we obtained a histological diagnosis; we controlled intracranial hypertension by treating the associated hydrocephalus and, above all, compared with a microsurgical approach, we reduced the risks related to dissection and brain retraction. Moreover, in both cases, neuroendoscopy enabled us to identify an initial, precocious subependymal tumor spreading below the threshold of magnetic resonance imaging (MRI) detection. This finding, undetected in pre-operative MRI scans, was then evident during follow-up neuroimaging studies. In light of these data, a neuroendoscopic approach might play a leading role in better defining the prognosis and optimally tailored management protocols for GBM and brain metastasis. PMID:23271915

    Brain metastasis is an ominous complication of cancer, yet most cancer cells that infiltrate the brain die of unknown causes. Here, we identify plasmin from the reactive brain stroma as a defense against metastatic invasion, and plasminogen activator (PA) inhibitory serpins in cancer cells as a shield against this defense. Plasmin suppresses brain metastasis in two ways: by converting membrane-bound astrocytic FasL into a paracrine death signal for cancer cells, and by inactivating the axon pathfinding molecule L1CAM, which metastatic cells express for spreading along brain capillaries and for metastatic outgrowth. Brain metastatic cells from lung cancer and breast cancer express high levels of anti-PA serpins, including neuroserpin and serpin B2, to prevent plasmin generation and its metastasis-suppressive effects. By protecting cancer cells from death signals and fostering vascular co-option, anti-PA serpins provide a unifying mechanism for the initiation of brain metastasis in lung and breast cancers.

    Uterine leiomyosarcoma is an aggressive malignancy. Spread to the lung, thyroid, liver, brain, pancreas, heart, duodenum, breast, vagina, submandibular gland, and bone has been reported. We describe a case of metastatic uterine leiomyosarcoma to the rectus abdominalis muscle as the first case in the literature. A 39-year-old nulligravid woman presented with a history of pelvic pain. Physical examination discovered about a 6-cm mass in the suprapubic region. She had previously undergone a hysterectomy for uterine leiomyosarcoma. Operative findings had revealed a mass measuring 4×5×6 cm located in the rectus abdominalis muscle. Abnormal mitotic figures and necrosis were evident, and uterine leiomyosarcoma was diagnosed. Uterine leiomyosarcomas are malignancies of the smooth muscle arising from the myometrium. Skeletal muscle is an uncommon site of metastasis by hematogenous spread. In conclusion, we have described a case of skeletal muscle metastasis (first case of rectus abdominalis muscle metastasis) secondary to uterine leiomyosarcoma. PMID:24976779

    Cholangiocarcinoma is a malignant disease of the epithelial cells in the intra- and extrahepatic bile ducts. It is the most frequent biliary malignancy. The lack of effective medical treatment makes a radical surgical resection the only therapeutic option. However, frequently Intrahepatic cholangiocarcinoma metastasize in lymphatic chains, including the hepatoduodenal ligament, and it often invades adjacent organs or metastasizes to other visceral organs such as the lungs, bones, adrenal glands, and brain and the prognosis remains poor. We present a case of elderly patient with a severe and progressive pain due to a pathologic fracture of humerus. The medical investigations revealed the presence of an intrahepatic cholangiocarcinoma.

    Melanoma brain metastasis is a complication with rising incidence. Despite the high rate of somatic mutations driving the initial stages of melanocyte transformation, the brain colonization requires a phenotypic reprogramming that is, in part, influenced by epigenomic modifications. This special report summarizes recent findings in the epigenomic landscape of melanoma progression to brain metastasis, with particular emphasis on the clinical utility of DNA methylation, chromatin modifications and ncRNA expression as theragnostic markers, as well as the significance of the metastatic microenvironment on melanoma brain metastasis epigenome.

    Metastasis remains the most common cause of death in most cancers, with limited therapies for combating disseminated disease. While the primary tumour microenvironment is an important regulator of cancer progression, it is less well understood how different tissue environments influence metastasis. We analysed tumour-stroma interactions that modulate organ tropism of brain, bone and lung metastasis in xenograft models. We identified a number of potential modulators of site-specific metastasis, including cathepsin S as a regulator of breast-to-brain metastasis. High cathepsin S expression at the primary site correlated with decreased brain metastasis-free survival in breast cancer patients. Both macrophages and tumour cells produce cathepsin S, and only the combined depletion significantly reduced brain metastasis in vivo. Cathepsin S specifically mediates blood-brain barrier transmigration through proteolytic processing of the junctional adhesion molecule, JAM-B. Pharmacological inhibition of cathepsin S significantly reduced experimental brain metastasis, supporting its consideration as a therapeutic target for this disease.

    Breast cancer brain metastasis is resistant to therapy and a particularly poor prognostic feature in patient survival. Altered metabolism is a common feature of cancer cells, but little is known as to what metabolic changes benefit breast cancer brain metastases. We found that brain metastatic breast cancer cells evolved the ability to survive and proliferate independent of glucose due to enhanced gluconeogenesis and oxidations of glutamine and branched chain amino acids, which together sustain the nonoxidative pentose pathway for purine synthesis. Silencing expression of fructose-1,6-bisphosphatases (FBP) in brain metastatic cells reduced their viability and improved the survival of metastasis-bearing immunocompetent hosts. Clinically, we showed that brain metastases from human breast cancer patients expressed higher levels of FBP and glycogen than the corresponding primary tumors. Together, our findings identify a critical metabolic condition required to sustain brain metastasis and suggest that targeting gluconeogenesis may help eradicate this deadly feature in advanced breast cancer patients.

    Tumor cell extravasation into the brain requires passage through the blood-brain barrier, which is a highly protected microvascular environment fortified with tight junction (TJ) proteins. TJ integrity can be regulated under physiological and pathophysiological conditions. There is evidence that exercise can modulate oxidation status within the brain microvasculature and protect against tumor cell extravasation and metastasis formation. In order to study these events, mature male mice were given access to voluntary exercise on a running wheel (exercise) or access to a locked wheel (sedentary) for five weeks. The average running distance was 9.0 ± 0.2 km/day. Highly metastatic tumor cells (murine Lewis lung carcinoma) were then infused into the brain microvasculature through the internal carotid artery. Analyses were performed at early stage (48 h) and late stage (3 weeks) post tumor cell infusion. Immunohistochemical analysis revealed fewer isolated tumor cells extravasating into the brain at both 48 h and 3 weeks post surgery in exercised mice. Occludin protein levels were reduced in the sedentary tumor group, but maintained in the exercised tumor group at 48 h post tumor cell infusion. These results indicate that voluntary exercise may participate in modulating blood-brain barrier integrity thereby protecting the brain during metastatic progression.

    BACKGROUND Metastases to the brain represent a feared complication and contribute to the morbidity and mortality of breast cancer. Despite improvements in therapy, prognostic factors for development of metastases are lacking. KISS1 is a metastasis suppressor that demonstrates inhibition of metastases formation in several types of cancer. The purpose of this study was to determine the importance of KISS1 expression in breast cancer progression and the development of intracerebral lesions. METHODS In this study, we performed a comparative analysis of 47 brain metastases and 165 primary breast cancer specimens by using the antihuman KISS1 antibody. To compare KISS1 expression between different groups, we used a 3-tier score and the automated score computer software (ACIS) evaluation. To reveal association between mRNA and protein expression, we used quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis. Significance of immunohistochemistry stainings was correlated with clinicopathological data. RESULTS We identified that KISS1 expression is significantly higher in primary breast cancer compared with brain metastases (P < .05). The mRNA analysis performed on 33 selected ductal carcinoma brain metastatic lesions and 36 primary ductal carcinomas revealed a statistically significant down-regulation of KISS1 protein in metastatic cases (P = .04). Finally, we observed a significant correlation between expression of KISS1 and metastasis-free survival (P = .04) along with progression of breast cancer and expression of KISS1 in primary breast cancer specimens (P = .044). CONCLUSIONS In conclusion, our study shows that breast cancer expresses KISS1. Cytoplasmic expression of KISS1 may be used as a prognostic marker for increased risk of breast cancer progression.

    Brain metastasis is a morbid, treatment-resistant, end-stage frequent occurrence in breast cancer patients. The aim of this study was to evaluate the efficacy of tumor-targeting Salmonella typhimurium A1-R on breast cancer brain metastases. High brain-metastatic variants of murine 4T1 breast cancer cells expressing red fluorescent protein (RFP) were injected orthotopically in the mammary fat pad in non-transgenic nude mice or in the left ventricle of non-transgenic nude mice and transgenic nude mice expressing nestin-driven green fluorescent protein (ND-GFP). ND-GFP mice express GFP in nascent blood vessels. In the orthotopically-injected mice, the primary tumor was surgically-resected in order to allow brain metastasis to develop. At various time points, the tumors and vasculature in the brain were imaged by confocal and stereo fluorescence microscopy. Some of the breast cancer cells that reached the brain extravasated and grew perivascularly and some of the cells proliferated within the vasculature. S. typhimurium A1-R significantly inhibited brain metastasis in both metastatic models and increased survival of the orthotopically-transplanted, primary-tumor-resected mice (p<0.05). The results of the present study suggest the clinical potential of bacterial therapy of breast cancer brain metastasis.

    Distant metastasis of primary neoplasms is the main factor that limits the success of antineoplastic therapy. It can be regarded as an early or late event in the neoplastic process, and varies considerably with tumor type. The metastatic potential of a given tumor greatly influences prognosis. Tumor metastasis is not a single neoplastic event, rather, it involves several major steps: invasion of cells from the primary tumor into tissue, and penetration of blood and lymph vessels; release of tumor cell emboli into the circulation; arrest of the emboli in capillary beds of distant organs; invasion of the wall of the arresting vessel, infiltration into adjacent tissue, and multiplication; and growth of vascularized stroma into the new tumor as proliferating tumor cells invade the distant organ. Lodgement and invasion are complex events that are not fully defined. Arrest and lodgement appears to require a thromboembolic event in which the metastatic embolis (1 cell) contacts vascular endothelium and adheres to the wall with thrombis formation following aggregation of platelets and fibrin to the tumor cell(s). Invasion may involve: formation of collagenases by tumor cells; mechanical disruption; chemotactic factors. Metastatic patterns depend on the route of metastasis, tumor type, and target organ (favored soil). In general, carcinomas metastasize via lymphatics and sarcomas via hematogenous routes. Others, melanoma, mast cell tumors, etc., show mixed patterns. This knowledge is important when one is attempting to prognostically stage a tumor, especially when thoracic radiographs are negative. The question of enlarged regional lymph nodes will be discussed in lecture relative to specific tumor types. 4 refs., 1 tab.

    There is a general consensus that breast cancer is a rising trend disease in the world. It is one of the most common cancer types and is the leading cause of death among women's cancers. There are several reasons for this high rate of mortality including metastasis which is responsible for about 90 % of cancer-related mortality. Therefore, recognition and understanding of metastatic process is important, and by considering the key role of pathophysiological route in metastasis as a multistep cascade of "invasion-metastasis," it might modify and improve our insight toward this complex phenomenon. Moreover, it can provide novel approaches for designing advanced targeted therapies. The present work aimed to review the published papers regarding molecular basis of metastatic process of breast cancer to brain metastasis, especially related genes and signaling network. Furthermore, the use of molecular aspects of metastatic breast cancer to brain was discussed in horizon of future treatment of breast cancer.

    Although breast cancer is the second most common cause of brain metastasis with a notable increase of incidence, genes that mediate breast cancer brain metastasis (BCBM) are not fully understood. To study the molecular nature of brain metastasis, we performed gene expression profiling of brain metastasis and matched primary breast cancer (BC). We used the Ion AmpliSeq Cancer Panel v2 covering 2,855 mutations from 50 cancer genes to analyze 18 primary BC and 42 BCBM including 15 matched pairs. The most common BCBM subtypes were triple-negative (42.9%) and basal-like (36.6%). In a total of 42 BCBM samples, 32 (76.2%) harbored at least one mutation (median 1, range 0-7 mutations). Frequently detected somatic mutations included TP53 (59.5%), MLH1 (14.3%), PIK3CA (14.3%), and KIT (7.1%). We compared BCBM with patient-matched primary BC specimens. There were no significant differences in mutation profiles between the two groups. Notably, gene expression in BCBM such as TP53, PIK3CA, KIT, MLH1, and RB1 also seemed to be present in primary breast cancers. The TP53 mutation frequency was higher in BCBM than in primary BC (59.5% vs 38.9%, respectively). In conclusion, we found actionable gene alterations in BCBM that were maintained in primary BC. Further studies with functional testing and a delineation of the role of these genes in specific steps of the metastatic process should lead to a better understanding of the biology of metastasis and its susceptibility to treatment.

    HER2-targeting antibodies (i.e. trastuzumab and pertuzumab) prolong survival in HER2-positive breast cancer patients with extracranial metastases. However, the response of brain metastases to these drugs is poor, and it is hypothesized that the blood-brain barrier (BBB) limits drug delivery to the brain. We investigated whether we could improve the response by temporary disruption of the BBB using focused ultrasound in combination with microbubbles. To study this, we inoculated 30 nude rats with HER2-positive cells derived from a brain metastasis of a breast cancer patient (MDA-MB-361). The animals were divided into three groups: a control-group that received no treatment; an antibody-only group that received six weekly treatments of trastuzumab and pertuzumab; and an ultrasound+antibody group that received trastuzumab and pertuzumab in combination with six weekly sessions of BBB disruption using focused ultrasound. In two animals, the leakiness of the tumors before disruption was evaluated using contrast-enhanced T1-weighted magnetic resonance imaging and found that the tumors were not leaky. The same technique was used to evaluate the effectiveness of BBB disruption, which was successful in all sessions. The tumor in the control animals grew exponentially with a growth constant of 0.042±0.011mm(3)/day. None of the antibody-only animals responded to the treatment and the growth constant was 0.033±0.009mm(3)/day during the treatment period. Four of the ten animals in the ultrasound+antibody-group showed a response to the treatment with an average growth constant of 0.010±0.007mm(3)/day, compared to a growth constant 0.043±0.013mm(3)/day for the six non-responders. After the treatment period, the tumors in all groups grew at similar rates. As the tumors were not leaky before BBB disruption and there were no responders in the antibody-only group, these results show that at least in some cases disruption of the BBB is necessary for a response to the antibodies in

    Glioma represents a disparate group of tumors characterized by high invasion ability, and therefore it is of clinical significance to identify molecular markers and therapeutic targets for better clinical management. Previously, metastasis-associated protein family (MTA) is considered to promote tumor cell invasion and metastasis of human malignancies. Recently, the newly identified MTA3 has been shown to play conflicting roles in human malignancies, while the expression pattern and potential clinical significance of MTA3 in human glioma have not been addressed yet. In the present study, we investigated the protein expression of MTA3 by immunohistochemistry assay and analyzed its association with glioma prognosis in 186 cases of patients. Results showed that MTA3 expression was decreased in glioma compared with that in normal brain (P < 0.05). In addition, tumors with high MTA3 expression were more likely to be of low WHO grade (P = 0.005) and reserve of body function (P = 0.014). Survival analysis showed that decreased MTA3 expression was independently associated with unfavorable overall survival of patients (P < 0.001). These results provide the first evidence that MTA3 expression was decreased in human glioma and negatively associated with prognosis of patients, suggesting that MTA3 may play a tumor suppressor role in glioma.

    Brain metastasis is a major cause of morbidity and mortality of lung cancer patients. We assessed whether aberrant expression of specific microRNAs could contribute to brain metastasis. Comparison of primary lung tumors and their matched metastatic brain disseminations identified shared patterns of several microRNAs, including common down-regulation of miR-145-5p. Down-regulation was attributed to methylation of miR-145's promoter and affiliated elevation of several protein targets, such as EGFR, OCT-4, MUC-1, c-MYC and, interestingly, tumor protein D52 (TPD52). In line with these observations, restored expression of miR-145-5p and selective depletion of individual targets markedly reduced in vitro and in vivo cancer cell migration. In aggregate, our results attribute to miR-145-5p and its direct targets pivotal roles in malignancy progression and in metastasis. PMID:26440147

    Currently, survival of breast cancer patients with brain metastasis ranges from 2 to 16 months. In experimental brain metastasis studies, only 10% of lesions with the highest permeability exhibited cytotoxic responses to paclitaxel or doxorubicin. Therefore, radiation is the most frequently used treatment, and sensitizing agents, which synergize with radiation, can improve the efficacy of the therapy. In this study we used 435-Br1 cells containing the fluorescent protein (eGFP) gene and the photinus luciferase (PLuc) gene to develop a new brain metastatic cell model in mice through five in vivo/in vitro rounds. BR-eGFP-CMV/Luc-V5 brain metastatic cells induce parenchymal brain metastasis within 60.8 ± 13.8 days of intracarotid injection in all mice. We used this model to standardize a preclinical chemoradiotherapy protocol comprising three 5.5 Gy fractions delivered on consecutive days (overall dose of 16.5 Gy) which improved survival with regard to controls (60.29 ± 8.65 vs. 47.20 ± 11.14). Moreover, the combination of radiotherapy with temozolomide, 60 mg/Kg/day orally for five consecutive days doubled survival time of the mice 121.56 ± 52.53 days (Kaplan-Meier Curve, p < 0.001).

    The case of a woman with a massive recurrent anterior mandibular ameloblastoma of 45 years' duration that showed metastasis is presented. The aggressive nature of the tumor, its management, and the eventual outcome are discussed. Ameloblastomas, particularly after their first recurrence, must be viewed as potentially life-threatening lesions. Adequate resection early in the onset of such tumors may result in more successful and predictable results. PMID:3476703

    Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the primary meningeal tumor. In this report, the clinicopathological features of 5 cases of metastatic HPC to the liver were reviewed and described. PMID:27044772

    Brain metastasis, a common complication of non-small cell lung cancer (NSCLC) with an incidence rate of 30%-50%, significantly affects the patients' quality of life. The prognosis of patients of NSCLC with brain metastasis is extremely poor, the average median survival is only 1 m-2 m without treatment. The targeted therapy based on lung cancer driven gene is a new treatment. Besides, the immunotherapy which can enhance the effect of anti-cancer by simulating the immune system is a new approach. The combination of targeted therapy and immunotherapy can greatly benefit patients in clinical work. PMID:27561803

    Small cell lung cancer is the most aggressive histologic subtype of lung cancer, with a strong predilection for metastasizing to brain early. However, the cellular and molecular basis is poorly known. Here, we provided evidence to reveal the role of annexin A1 in small cell lung cancer metastasis to brain. Firstly, the elevated annexin A1 serum levels in small cell lung cancer patients were associated with brain metastasis. The levels of annexin A1 were also upregulated in NCI-H446 cells, a small cell lung cancer cell line, upon migration into the mice brain. More interestingly, annexin A1 was secreted by NCI-H446 cells in a time-dependent manner when co-culturing with human brain microvascular endothelial cells, which was identified with the detections of annexin A1 in the co-cultured cellular supernatants by ELISA and western blot. Further results showed that blockage of annexin A1 in the co-cultured cellular supernatants using a neutralized antibody significantly inhibited NCI-H446 cells adhesion to brain endothelium and its transendothelial migration. Conversely, the addition of Ac2-26, an annexin A1 mimic peptide, enhanced these effects. Furthermore, knockdown of annexin A1 in NCI-H446 cells prevented its transendothelial migration in vitro and metastasis to mice brain in vivo. Our data showed that small cell lung cancer cell in brain microvasculature microenvironment could express much more annexin A1 and release it outside, which facilitated small cell lung cancer cell to gain malignant properties of entry into brain. These findings provided a potential target for the management of SCLC brain metastasis. PMID:26135980

    Metastatic temporal bone tumors are rare, and tend to be asymptomatic. The clinical symptoms consist of aural discharge, bleeding, hearing loss and facial nerve paresis. The most common origin of the metastasis is breast cancer, and other sites of the primary tumor include the thyroid gland, brain, lungs, prostate and blood. Clinical reports of hearing loss due to gastric cancer metastatic to temporal bone are rare. In the present study, a case of gastric cancer metastasis to temporal bone without other organ involvement is described. The patient presented with the symptom of hearing loss, and the metastatic tumor was diagnosed by radiological imaging, including magnetic resonance imaging, computed tomography and bone scan.

    Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for approximately 1% of all bone tumors and characteristically arises in the epiphysis of a long bone, particularly the humerus, tibia, and femur. Chondroblastoma can affect people of all ages. It is, however, most common in children and young adults between the ages of 10 and 20 years. Although most chondroblastomas are cured by limited surgical procedures, occasional lesions behave more aggressively and may even metastasis. In this case a young man with pulmonary metastatic chondroblastoma on spine is presented. Unlike previously published examples of metastatic chondroblastoma, these metastasis developed before any operative manipulation of the primary tumor. And primary tumor site was also unusual. The histologic characteristics of the primary, metastatic tumors were those of a conventional chondroblastoma. PMID:20057972

This is the case despite advances in imaging technology and surgical management. Indeed, 80% to 90% of pancreatic cancers are diagnosed either at the locally advanced or metastatic stage. Cutaneous metastases originating from pancreatic cancer are relatively rare. The most common site of cutaneous metastasis is the umbilicus, and this is known as the Sister Joseph's nodule. Very few patients have been reported with cutaneous lesions disclosing a pancreatic carcinoma at sites other than the umbilical area. To the best of our knowledge, there have been no previous reports on cutaneous pancreatic metastasis in Egypt. This is a report on a patient with cutaneous pancreatic metastases at the neck and review of reported non-umbilical cutaneous metastases from pancreatic carcinoma in the literatures.

    Cerebral metastases are the most common brain neoplasms seen clinically in the adults and comprise more than half of all brain tumours. Actual treatment options for brain metastases that include surgical resection, radiotherapy and chemotherapy are rarely curative, although palliative treatment improves survival and life quality of patients carrying brain-metastatic tumours. Chemotherapy in particular has also shown limited or no activity in brain metastasis of most tumour types. Many chemotherapeutic agents used systemically do not cross the blood-brain barrier (BBB), whereas others may transiently weaken the BBB and allow extravasation of tumour cells from the circulation into the brain parenchyma. Increasing evidence points out that the interaction between the BBB and tumour cells plays a key role for implantation and growth of brain metastases in the central nervous system. The BBB, as the tightest endothelial barrier, prevents both early detection and treatment by creating a privileged microenvironment. Therefore, as observed in several in vivo studies, precise targetting the BBB by a specific transient opening of the structure making it permeable for therapeutic compounds, might potentially help to overcome this difficult clinical problem. Moreover, a better understanding of the molecular features of the BBB, its interrelation with metastatic tumour cells and the elucidation of cellular mechanisms responsible for establishing cerebral metastasis must be clearly outlined in order to promote treatment modalities that particularly involve chemotherapy. This in turn would substantially expand the survival and quality of life of patients with brain metastasis, and potentially increase the remission rate. Therefore, the focus of this review is to summarise the current knowledge on the role and function of the BBB in cancer metastasis.

    Gastric cancer is the second most common cause of cancer-related death worldwide. Although brain metastasis is a rare complication of gastric cancer, no standard therapy for gastric cancer brain metastasis has been established. We attempted to identify biological markers that predict brain metastasis, and investigated how to modulate such markers. A case-control study of patients newly diagnosed with gastric cancer who had developed brain metastasis during follow-up, was conducted. These patients were compared with patients who had advanced gastric cancer but no evidence of brain metastasis. Immunohistochemistry was used to analyze the expression of E-cadherin, N-cadherin, MSS1, claudin-3, claudin-4, Glut1, clusterin, ITGB4, vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR) and p53. The expression of VEGF tended to be higher in the case group (33.3 vs. 0%, p=0.055). Median survival was significantly correlated with vascular invasion (12 vs. 33 months, p=0.008) and N-cadherin expression (36 vs. 12 months, p=0.027). We also investigated the effects of metformin in tumor-bearing mouse models. VEGF expression was decreased and E-cadherin increased in the metformin‑treated group when compared with the control group. The expression of the mesenchymal marker MMP9 was decreased in the metformin-treated group. Brain metastasis of advanced gastric cancer was associated with the expression of VEGF. Metformin treatment may be useful for modulating the metastatic capacity by reducing VEGF expression and blocking epithelial-to-mesenchymal transition.

    Background Breast cancer frequently metastasizes to the brain, colonizing a neuro-inflammatory microenvironment. The molecular pathways facilitating this colonization remain poorly understood. Methods Expression profiling of 23 matched sets of human resected brain metastases and primary breast tumors by two-sided paired t test was performed to identify brain metastasis–specific genes. The implicated DNA repair genes BARD1 and RAD51 were modulated in human (MDA-MB-231-BR) and murine (4T1-BR) brain-tropic breast cancer cell lines by lentiviral transduction of cDNA or short hairpin RNA (shRNA) coding sequences. Their functional contribution to brain metastasis development was evaluated in mouse xenograft models (n = 10 mice per group). Results Human brain metastases overexpressed BARD1 and RAD51 compared with either matched primary tumors (1.74-fold, P < .001; 1.46-fold, P < .001, respectively) or unlinked systemic metastases (1.49-fold, P = .01; 1.44-fold, P = .008, respectively). Overexpression of either gene in MDA-MB-231-BR cells increased brain metastases by threefold to fourfold after intracardiac injections, but not lung metastases upon tail-vein injections. In 4T1-BR cells, shRNA-mediated RAD51 knockdown reduced brain metastases by 2.5-fold without affecting lung metastasis development. In vitro, BARD1- and RAD51-overexpressing cells showed reduced genomic instability but only exhibited growth and colonization phenotypes upon DNA damage induction. Reactive oxygen species were present in tumor cells and elevated in the metastatic neuro-inflammatory microenvironment and could provide an endogenous source of genotoxic stress. Tempol, a brain-permeable oxygen radical scavenger suppressed brain metastasis promotion induced by BARD1 and RAD51 overexpression. Conclusions BARD1 and RAD51 are frequently overexpressed in brain metastases from breast cancer and may constitute a mechanism to overcome reactive oxygen species–mediated genotoxic stress in the metastatic

    Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with respect to pituitary involvement. The most common primary sites are breast in women and lung in men. We present the case of a 64-year-old patient with clinical visual changes, polyuria, polydipsia, and decreased level of consciousness whose tests showed pan-hypopituitarism, hypernatremia and low urine specific gravity, and extensive mass in sellar region. Diabetes insipidus was confirmed and treated, corticotrophic and thyroid deficits were corrected and then the patient underwent resection by transsphenoidal surgery. The histopathological and immunohistochemistry analysis revealed pituitary metastasis of lung neuroendocrine tumor. Subsequently, a chest CT scan showed pulmonary mass consistent with primary neoplasm. Despite the water and electrolyte correction and intravenous glucocorticoid replacement, the patient continued to show decreased level of consciousness due to compression of the brain stem by the pituitary mass, evolving to death. The purpose is to call attention to the differential diagnosis of invasive lesions of the sellar region, mainly in individuals over 50 years and/or when associated with diabetes insipidus, as it may be a case of metastasis, although there is no known primary neoplasm.

    Background The brain is a metastatic organ that is most prone to lung adenocarcinoma (LAC). However, the prognosis of patients with brain metastasis remains very poor. In this study, we evaluated the efficacy of icotinib plus whole brain radiation therapy (WBRT) for treating patients with brain metastasis from epidermal growth factor receptor (EGFR)-mutated LAC. Methods All patients received standard WBRT administered to the whole brain in 30 Gy in 10 daily fractions. Each patient was also instructed to take 125 mg icotinib thrice per day beginning from the first day of the WBRT. After completing the WBRT, maintenance icotinib was administered until the disease progressed or intolerable adverse effects were observed. Cranial progression-free survival (CPFS) and overall survival (OS) times were the primary endpoints. Results A total of 43 patients were enrolled in this study. Two patients (4.7%) presented a complete response (CR), whereas 20 patients (46.5%) presented a partial response (PR). The median CPFS and OS times were 11.0 and 15.0 months, respectively. The one-year CPFS rate was 40.0% for the patients harboring EGFR exon 19 deletion and 16.7% for the patients with EGFR exon 21 L858R (P=0.027). Conclusions The concurrent administration of icotinib and WBRT exhibited favorable effects on the patients with brain metastasis. EGFR exon 19 deletion was predictive of a long CPFS following icotinib plus WBRT. PMID:27499937

    Brain metastasis represents a substantial source of morbidity and mortality in various cancers, and is characterized by high resistance to chemotherapy. Here we define the role of the most abundant cell type in the brain, the astrocyte, in promoting brain metastasis. We show that human and mouse breast and lung cancer cells express protocadherin 7 (PCDH7), which promotes the assembly of carcinoma-astrocyte gap junctions composed of connexin 43 (Cx43). Once engaged with the astrocyte gap-junctional network, brain metastatic cancer cells use these channels to transfer the second messenger cGAMP to astrocytes, activating the STING pathway and production of inflammatory cytokines such as interferon-α (IFNα) and tumour necrosis factor (TNF). As paracrine signals, these factors activate the STAT1 and NF-κB pathways in brain metastatic cells, thereby supporting tumour growth and chemoresistance. The orally bioavailable modulators of gap junctions meclofenamate and tonabersat break this paracrine loop, and we provide proof-of-principle that these drugs could be used to treat established brain metastasis.

    Breast cancer brain metastasis is resistant to therapy and a particularly poor prognostic feature in patient survival. Altered metabolism is a common feature of cancer cells but little is known as to what metabolic changes benefit breast cancer brain metastases. We found that brain-metastatic breast cancer cells evolved the ability to survive and proliferate independent of glucose due to enhanced gluconeogenesis and oxidations of glutamine and branched chain amino acids, which together sustain the non-oxidative pentose pathway for purine synthesis. Silencing expression of fructose-1,6-bisphosphatases (FBPs) in brain metastatic cells reduced their viability and improved the survival of metastasis-bearing immunocompetent hosts. Clinically, we showed that brain metastases from human breast cancer patients expressed higher levels of FBP and glycogen than the corresponding primary tumors. Together, our findings identify a critical metabolic condition required to sustain brain metastasis, and suggest that targeting gluconeogenesis may help eradicate this deadly feature in advanced breast cancer patients.

    Pituitary metastasis is an uncommon first presentation of systemic malignancy. The most common presenting symptom of pituitary metastasis is diabetes insipidus reflecting involvement of the stalk and/or posterior pituitary. We herein present a unique case of the coexistence of both a functioning pituitary adenoma (prolactinoma) and pituitary metastasis of advanced colorectal cancer with pituitary apoplexy as the first manifestation of underlying malignancy. The present case emphasizes the need to consider pituitary metastasis as a differential diagnosis in patients presenting with pituitary lesions and be aware that tumor-to-tumor metastasis can occur unexpectedly in those with pituitary metastases.

    Introduction A primary cancer causing thyroid metastasis is extremely rare. In western countries, the most common primary tumors causing thyroid metastases include kidney, lung, breast, and gastrointestinal cancers. In contrast, breast is the most common primary site, followed by kidney, colon, and lung cancers in Korea. To the best of our knowledge, surgically confirmed thyroid metastasis from cholangiocarcinoma has not been reported. Herein, we report the first case of thyroid metastasis secondary to cholangiocarcinoma on which surgery was performed. Presentation of case A 55-year-old man was diagnosed with hepatic malignancy in December 2008. He subsequently received 2 cycles of transarterial chemoembolization and 4 cycles of radio-frequency ablation between 2008 and 2010. At follow-up in January 2011, brain metastasis was identified in the right parietal area secondary to cholangiocarcinoma. In April 2011, the patient was found to have palpable masses on the left thyroid and lateral neck. The patient subsequently underwent total thyroidectomy followed by left radical neck dissection. Intraoperatively, an ill-defined mass measuring 6.0 cm was found infiltrating the subcutaneous tissue into the prevertebral fascia. Microscopic and immunohistochemical findings confirmed that the thyroid masses and lymph nodes were metastatic cholangiocarcinoma. Discussion Positive immunohistochemical staining for cytokeratin 7, cytokeratin 19, and AFP and negative results for TG, TTF-1, and cytokeratin 20 can be definitely helpful in arriving at a correct diagnosis. Conclusion To the best of our knowledge, this is the first case report on surgically resected thyroid and lateral neck metastases secondary to cholangiocarcinoma. PMID:22288052

    In this case report we describe rare metastatic appearance of cutaneous malignant melanoma ( MM) in small intestine followed by clinical appearance of acute surgical abdomen. A 42-year old women operated in our hospital in April 2009. due to unusual naevus on her right arm. Pathologicaly it was MM grossly 1.5 cm, microscopically Breslow 11 mm, Clark's level IV (T4), number of mitosis 1.4 per mm2, without ulcerations. She was sent to continue treatment at the National Referal Center for Melanoma in KB "S. milosrdnice" Zagreb, Croatia. A month later wider excision (3 cm free margin) and sentinel lymph node biopsy (SLNB) was made there followed by axillary lymphadenectomy due to positive axillary finding. She received six cycles of chemotherapy. She arrived in our hospital in May 2010, under clinical picture of small intestine ileus and acute surgical abdomen. After preparation she was operated the same day. The cause of ileus was metastasis of MM in the small interstine. We made intestinal resection with termino-terminal anastomosis. The patient was released to home care ten days after operation without any complication. This case report demonstrates rarely described case of MM metastasis in the small intestine found causing ileus. PMID:22359897

    The development of life-threatening cancer metastases at distant organs requires disseminated tumour cells' adaptation to, and co-evolution with, the drastically different microenvironments of metastatic sites. Cancer cells of common origin manifest distinct gene expression patterns after metastasizing to different organs. Clearly, the dynamic interaction between metastatic tumour cells and extrinsic signals at individual metastatic organ sites critically effects the subsequent metastatic outgrowth. Yet, it is unclear when and how disseminated tumour cells acquire the essential traits from the microenvironment of metastatic organs that prime their subsequent outgrowth. Here we show that both human and mouse tumour cells with normal expression of PTEN, an important tumour suppressor, lose PTEN expression after dissemination to the brain, but not to other organs. The PTEN level in PTEN-loss brain metastatic tumour cells is restored after leaving the brain microenvironment. This brain microenvironment-dependent, reversible PTEN messenger RNA and protein downregulation is epigenetically regulated by microRNAs from brain astrocytes. Mechanistically, astrocyte-derived exosomes mediate an intercellular transfer of PTEN-targeting microRNAs to metastatic tumour cells, while astrocyte-specific depletion of PTEN-targeting microRNAs or blockade of astrocyte exosome secretion rescues the PTEN loss and suppresses brain metastasis in vivo. Furthermore, this adaptive PTEN loss in brain metastatic tumour cells leads to an increased secretion of the chemokine CCL2, which recruits IBA1-expressing myeloid cells that reciprocally enhance the outgrowth of brain metastatic tumour cells via enhanced proliferation and reduced apoptosis. Our findings demonstrate a remarkable plasticity of PTEN expression in metastatic tumour cells in response to different organ microenvironments, underpinning an essential role of co-evolution between the metastatic cells and their microenvironment during

Histopathological examination confirmed invasion of the pineal gland by metastatic urothelial carcinoma. This case highlighted that the presence of pineal lesions in patient with known malignancy should raise suspicion of metastatic involvement. PMID:27149501

    Introduction: Aspergilloma is a fungal ball which is composed of hyphal structure fungus, fibrin, mucus and cellular debris and settled in a pre-existing pulmonary cavity or an ectatic bronchial. It may cause colonization in patients with an immunosuppressive and underlying lung disease. Although chest radiography provides valuable information, it can be scanned more effectively by computed tomography (CT). Monitoring fungal ball within the cavity in CT provides establishing the diagnosis. Case report: However, in this case report, we presented a case with operated laryngeal carcinoma whom we first had considered to have metastasis and who had received a diagnosis of aspergilloma in CT and Positron emission tomography (PET). Conclusion: Imaging findings may remain limited in definitive diagnosis of aspergilloma. Therefore, surgical resection will allow for both pathological diagnosis and treatment. PMID:26980939

    Intramedullary spinal cord metastasis is quite rare. This report presents the case of a female patient with metastasis of the conus medullaris from breast cancer, presenting with paraplegia and sphincter dysfunction. Bladder dysfunction improved after removal of the conus mass. This report is the seventh case of conus medullaris metastasis from breast cancer and the first review of clinical outcome, survival time and other data of all these 7 cases. This study also reviewed cases of intramedullary spinal cord metastasis arising from breast cancer in regions other than the conus medullaris in the literature. Longer survival time resulted from surgery in contrast to those without surgery in the latter group.

    It has been demonstrated that erlotinib is effective in treating patients with brain metastasis from non-small-cell lung cancer. However, the number of studies determining the erlotinib concentration in these patients is limited. The purpose of this study was to measure the concentration of erlotinib in the cerebrospinal fluid of patients with brain metastasis from non-small-cell lung carcinoma. Six patients were treated with the standard recommended daily dose of erlotinib (150 mg) for 4 weeks. All the patients had previously received chemotherapy, but no brain radiotherapy. At the end of the treatment period, blood plasma and cerebrospinal fluid samples were collected and the erlotinib concentration was determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The average erlotinib concentration in the blood plasma and the cerebrospinal fluid was 717.7±459.7 and 23.7±13.4 ng/ml, respectively. The blood-brain barrier permeation rate of erlotinib was found to be 4.4±3.2%. In patients with partial response (PR), stable disease (SD) and progressive disease (PD), the average concentrations of erlotinib in the cerebrospinal fluid were 35.5±19.0, 19.1±8.7 and 16.4±5.9 ng/ml, respectively. In addition, the efficacy rate of erlotinib for metastatic brain lesions was 33.3%, increasing to 50% in patients with EGFR mutations. However, erlotinib appeared to be ineffective in cases with wild-type EGFR. In conclusion, a relatively high concentration of erlotinib was detected in the cerebrospinal fluid of patients with brain metastases from non-small-cell lung cancer. Thus, erlotinib may be considered as a treatment option for this patient population. PMID:24649318

    We examined the records of 33 patients who presented with the clinico-radiological diagnosis of solitary brain metastasis and no other evidence of tumor dissemination. Length of survival of patients and patterns of treatment failure were analyzed according to the treatment modalities that were used. Both groups were comparable regarding major parameters that affect response and survival in patients with brain metastasis. There did not appear to be any significant advantage to the use of irradiation following excision, at least at the doses employed in this study. We advocate the use of higher doses of irradiation in any curative attempt following total excision of a solitary brain metastasis.

    Apoplexy in sellar metastasis is very rare with only a few case reports in literature. A case of apoplexy in sellar metastasis from follicular thyroid carcinoma is reported and the literature is briefly reviewed. The patient presented with sudden onset headache and bi-lateral loss of vision following thyroidectomy in a case of follicular carcinoma thyroid with proven sellar metastasis. CT scan showed hyperdense blood in sellar mass suggestive of apoplexy in sellar metastasis. The patient underwent early trans-sphenoidal decompression. Apoplexy in sellar metastasis, although very rare, can be clinico-radiologically indistinguishable from pituitary apoplexy and should be especially considered in the differential diagnosis of patients with known primary neoplastic disease. In view of similar patho-physiological mechanism, sellar metastasis with apoplexy should be managed in a similar manner as pituitary apoplexy. PMID:21534208

    Purpose: Iodine-enhanced radiotherapy is an innovative treatment combining the selective accumulation of an iodinated contrast agent in brain tumors with irradiations using monochromatic medium energy x-rays. The aim of this study is to compare dynamic stereotactic arc-therapy and iodineenhanced SSRT. Methods: Five patients bearing brain metastasis received a standard helical 3D-scan without iodine. A second scan was acquired 13 min after an 80 g iodine infusion. Two SSRT treatment plans (with/without iodine) were performed for each patient using a dedicated Monte Carlo (MC) treatment planning system (TPS) based on the ISOgray TPS. Ten coplanar beams (6×6 cm2, shaped with collimator) were simulated. MC statistical error objective was less than 5% in the 50% isodose. The dynamic arc-therapy plan was achieved on the Iplan Brainlab TPS. The treatment plan validation criteria were fixed such that 100% of the prescribed dose is delivered at the beam isocentre and the 70% isodose contains the whole target volume. The comparison elements were the 70% isodose volume, the average and maximum doses delivered to organs at risk (OAR): brainstem, optical nerves, chiasma, eyes, skull bone and healthy brain parenchyma. Results: The stereotactic dynamic arc-therapy remains the best technique in terms of dose conformation. Iodine-enhanced SSRT presents similar performances to dynamic arc-therapy with increased brainstem and brain parenchyma sparing. One disadvantage of SSRT is the high dose to the skull bone. Iodine accumulation in metastasis may increase the dose by 20–30%, allowing a normal tissue sparing effect at constant prescribed dose. Treatment without any iodine enhancement (medium-energy stereotactic radiotherapy) is not relevant with degraded HDVs (brain, parenchyma and skull bone) comparing to stereotactic dynamic arc-therapy. Conclusion: Iodine-enhanced SSRT exhibits a good potential for brain metastasis treatment regarding the dose distribution and OAR criteria.

    Neuroendocrine carcinomas (NECs) of the esophagus are very rare. The majority of the patients with NECs present with metastasis. Paraneoplastic syndromes, such as syndrome of inappropriate secretion of anti-diuretic hormone and watery diarrhea-hypokalemia-achlorhydria syndrome, have been reported in previous reports. Esophageal NECs are related to a poor prognosis. A 38-year-old male with the histologic diagnosis of esophageal NEC, which initially manifested as hypertrophic osteoarthropathy (HOA), later developed brain metastases. He was initially treated with neoadjuvant chemotherapy consisting of cisplatin and etoposide followed by a partial esophagectomy in November 2009. At follow-up in February 2010, he complained of a headache that prompted imaging. MRI of the brain revealed a left frontal lobe lesion. Subsequently, he underwent a craniotomy and resection of the lesion. Pathological analysis revealed that the lesion was consistent with metastatic disease from the primary esophageal NEC. The patient underwent 40 Gy whole brain radiotherapy (WBRT), followed by two weeks of stereotactic radiation (SRS) to the tumor bed for an additional 12 Gy. During this time, his tumor marker neuron-specific enolase (NSE) initially dropped but later increased, which led us to offer him radiotherapy to the remaining esophagus to be followed by localized radiation to areas immediately adjacent to the surgical site, followed by six cycles of systemic chemotherapy consisting of cisplatin and irinotecan. Finally, his NSE normalized around the end of systemic chemotherapy. Surveillance imaging in 2015 - six years from initial diagnosis - showed no evidence of cancer. Of interest, treatment of the esophageal NEC also led to clinical resolution of his musculoskeletal symptoms, including his HOA. High-grade esophageal NECs are rare, aggressive, and have a poor prognosis. HOA can be a presenting sign associated with a high-grade esophageal NEC. The predominant site of metastatic

    Cardiac metastasis from known cervical cancer is rare. Even through a routine check-up, this type of metastasis can present as pulmonary emboli. Suspicion of this diagnosis in an oncology patient with complicating pulmonary emboli but no evidence of deep vein thrombosis is important, especially in cervical cancer patients with extensive pelvic lymph node metastasis and vascular invasion of a primary tumor. Early recognition may aid in improving the prognosis. We present a case of intracardiac metastasis arising from a squamous carcinoma of the cervix in a patient with pulmonary tumor emboli and review other cases from the literature.

    Background/Objectives The molecular chaperone αB-crystallin is expressed in estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 “triple-negative” breast carcinomas and promotes brain and lung metastasis. We examined αB-crystallin expression in primary breast carcinomas with metastatic data to evaluate its association with prognosis and site-specific metastases. Methods αB-crystallin gene (CRYAB) expression was examined using publically available global-gene expression data (n=855 breast tumors) with first site of distant metastasis information (“855Met”). αB-crystallin protein expression was determined by immunohistochemistry using the clinically annotated tissue microarray (n=3987 breast tumors) from British Columbia Cancer Agency (BCCA). Kaplan-Meier and multivariable Cox regression analyses were used to evaluate the prognostic value of αB-crystallin. Multivariable logistic regression analysis was used to evaluate risks of αB-crystallin and other markers for site of metastasis. Results In the 855Met dataset, αB-crystallin gene (CRYAB) expression was an independent predictor of brain as the first distant site of relapse (HR = 1.2, (95% CI 1.0-1.4), P = 0.021). In the BCCA series, αB-crystallin protein expression was an independent prognostic marker of poor breast cancer specific survival (HR = 1.3, (95% CI 1.1-1.6), P = 0.014). Among patients with metastases, αB-crystallin was the strongest independent predictor of brain metastasis (OR = 2.99 (95% CI 1.83-4.89), P < 0.0001) and the only independent predictor of brain as the first site of distant metastasis (OR = 3.15 (95% CI1.43-6.95), P = 0.005). αB-crystallin was also associated with worse survival (3.0 versus 4.7 months, P = 0.007). Conclusions αB-crystallin is a promising biomarker to identify breast cancer patients at high risk for early relapse in the brain, independent of ER and HER2 status.

    Brain metastasis is a significant unmet clinical problem in breast cancer treatment. It is always associated with poor prognosis and high morbidity. Recently, Slit2/Robo1 pathway has been demonstrated to be involved in the progression of breast carcinoma. However, until present, there are no convincing reports that suggest whether the Slit2/Robo1 axis has any role in brain metastasis of breast cancer. In this study, we investigated the correlation between Slit2/Robo1 signaling and breast cancer brain metastasis for the first time. Our results demonstrated that (1) Invasive ductal carcinoma patients with low expression of Slit2 or Robo1 exhibited worse prognosis and brain-specific metastasis, but not liver, bone or lung. (2) Lower expression of Slit2 and Robo1 were observed in patients with brain metastasis, especially in their brain metastasis tumors, compared with patients without brain metastasis. (3) The interval from diagnosis of breast cancer to brain metastasis and brain metastasis to death were both much shorter in patients with low expression of Slit2 or Robo1 compared with the high expression group. Overall, our findings indicated that Slit2/Robo1 axis possibly be regarded as a significant clinical parameter for predicting brain metastasis in breast cancer patients.

    Most cancer patients with brain metastases are treated with radiation therapy, yet this modality has not yet been meaningfully incorporated into preclinical experimental brain metastasis models. We applied two forms of whole brain radiation therapy (WBRT) to the brain-tropic 231-BR experimental brain metastasis model of triple-negative breast cancer. When compared to sham controls, WBRT as 3 Gy × 10 fractions (3 × 10) reduced the number of micrometastases and large metastases by 87.7 and 54.5 %, respectively (both p < 0.01); whereas a single radiation dose of 15 Gy × 1 (15 × 1) was less effective, reducing metastases by 58.4 % (p < 0.01) and 47.1 % (p = 0.41), respectively. Neuroinflammation in the adjacent brain parenchyma was due solely to a reaction from metastases, and not radiotherapy, while adult neurogenesis in brains was adversely affected following both radiation regimens. The nature of radiation resistance was investigated by ex vivo culture of tumor cells that survived initial WBRT ("Surviving" cultures). The Surviving cultures surprisingly demonstrated increased radiosensitivity ex vivo. In contrast, re-injection of Surviving cultures and re-treatment with a 3 × 10 WBRT regimen significantly reduced the number of large and micrometastases that developed in vivo, suggesting a role for the microenvironment. Micrometastases derived from tumor cells surviving initial 3 × 10 WBRT demonstrated a trend toward radioresistance upon repeat treatment (p = 0.09). The data confirm the potency of a fractionated 3 × 10 WBRT regimen and identify the brain microenvironment as a potential determinant of radiation efficacy. The data also nominate the Surviving cultures as a potential new translational model for radiotherapy.

    The best treatment approach for solitary brain metastasis is not well defined and there is no consensus on this issue. It is still being debated whether patients with isolated brain metastasis should undergo surgical resection or stereotactic radiosurgery, and which patients should receive adjuvant whole brain radiotherapy. The median survival in patients with single or multiple metastatic lesions who underwent only stereotactic radiosurgery improved from two-three months to nine months. To the best of our knowledge this is the first report on patients treated with linear accelerator-based stereotactic radiosurgery alone where an overall survival of more than 12 years was obtained, maintaining good quality of life in three cases of solitary brain metastasis from non-small cell lung cancer. In addition to the case reports, we present a brief literature review on this topic. PMID:22677999

    Colon cancer is the second most common type of cancer in females and the third in males, worldwide. The most common sites of colon cancer metastasis are the regional lymph nodes, liver, lung, bone and brain. In this study, an extremely rare case of colon adenocarcinoma with extensive metastasis to the mediastinal lymph nodes without any other organ involvement is presented. A 44-year-old Caucasian male presented with abdominal pain, a change in bowel habits, melena and weight loss. Colonoscopy revealed a large friable, ulcerated, circumferential mass in the ascending colon. Biopsies were consistent with the diagnosis of invasive moderately differentiated adenocarcinoma. Subsequently, right colon resection was performed, and pathological analysis revealed moderately differentiated adenocarcinoma of the right colon with extensive regional lymph node involvement. Computed tomography (CT) scans of the chest, abdomen and pelvis were performed preoperatively as part of routine staging for colon cancer. No liver or lung pathology was identified; however, multiple pathologically enlarged mediastinal lymph nodes were observed. Endoscopic ultrasound with fine needle aspiration of the largest mediastinal lymph node, which measured 5.2×3.5 cm on CT scans, was performed. The pathology was again consistent with the diagnosis of metastatic colorectal primary adenocarcinoma. At present, no optimum treatment has been identified for metastatic colon cancer to the mediastinal lymph nodes. The patient in the current case received chemotherapy with folinic acid, fluorouracil and oxaliplatin (FOLFOX), as well as with bevacizumab. Initial follow-up CT scans of the chest revealed a positive response to treatment. Physicians, in particular, radiologists, must consider the mediastinum during the first evaluation and further follow-up of patients with colorectal carcinoma even in the absence of metastasis.

    Introduction Metachronous metastatic spread of clinically localized renal cell carcinoma (RCC) affects almost 1/3 of the patients. They occur most frequently in lung, liver, bone and brain. Isolated omental metastasis of RCC has not been reported so far. Case presentation A 62-year-old patient previously diagnosed and treated due to pulmonary sarcoidosis has developed an omental metastatic lesion 13 years after having undergone open extraperitoneal partial nephrectomy for T1 clear-cell RCC. Constitutional symptoms and imaging findings that were attributed to the presence of a sarcomatoid paraneoplastic syndrome triggered by the development this metastatic focus complicated the diagnostic work-up. Biopsy of the [18F]-fluorodeoxyglucose (+) lesions confirmed the diagnosis of metastatic RCC and the patient was managed by the resection of the omental mass via near-total omentectomy followed by targeted therapy with a tyrosine kinase inhibitor. Discussion Late recurrence of RCC has been reported to occur in 10–20% of the patients within 20 years. Therefore lifelong follow up of RCC has been advocated by some authors. Diffuse peritoneal metastases have been reported in certain RCC subtypes with adverse histopathological features. However, isolated omental metastasis without any sign of peritoneal involvement is an extremely rare condition. Conclusion To our knowledge, this is the first reported case of metachronously developed, isolated omental metastasis of an initially T1 clear-cell RCC. Constitutional symptoms, despite a long interval since nephrectomy, should raise the possibility of a paraneoplastic syndrome being associated with metastatic RCC. Morphological and molecular imaging studies together with histopathological documentation will be diagnostic. PMID:26874583

    Purpose: To retrospectively evaluate prognostic factors that correlate with overall survival among patients with a surgically resected single brain metastasis. Methods and Materials: An Institutional Review Board-approved database of Cleveland Clinic Brain Tumor Institute was queried for patients with a single brain metastasis treated by surgical resection between February 1984 and January 2004. The primary endpoint was overall survival from the date of surgery by the Kaplan-Meier method. Results: A total of 271 patients were included. Statistically significant variables for improved survival on multivariate analysis included age <65 years, lack of extracranial metastases, control of primary tumor, histology (non-small-cell lung carcinoma), and use of stereotactic radiosurgery. The median survival for all patients was 10.2 months. Survival of patients in recursive partitioning analysis (RPA) class 1 was better (21.4 months) than those in RPA class 2 (9.0 months, p < 0.001), RPA class 3 (8.9 months, p = 0.15), or the combined group of RPA classes 2 and 3 (9.0 months, p < 0.001). Patients had a median survival of 10.6 months after documented gross total resection and 8.7 months after subtotal resection, which approached statistical significance (p 0.07). Those who were treated with stereotactic radiosurgery had a median survival of 17.1 months, which was greater than patients who were not treated with stereotactic radiosurgery (8.9 months, p = 0.006). Conclusions: This analysis supports the prognostic significance of the RPA classification in patients with a single brain metastasis who undergo surgical resection and adjuvant therapy. RPA class 1 patients have a very favorable prognosis with a median survival of 21.4 months.

Breast metastasis from lung adenocarcinoma can mimic triple-negative breast cancer. Given the prognosis and therapeutic challenges, a correct diagnosis appears essential, and molecular biomarkers could be useful. We report the case of a 52-year-old woman with a breast mass initially diagnosed as primary breast cancer and secondarily attached to breast metastasis from an EGFR-mutated lung adenocarcinoma. The same activating EGFR mutations were identified in both the primary lung carcinoma and the breast metastasis.

    The present study reports a case of a 59-year-old male suffering from oligodendroglioma that metastasized to the bone marrow (BM). The metastasis was detected 5 years after craniotomy was performed for the resection of the primary tumor; however, it manifested as multiple myeloma (MM)-like bone lesions, a small M component and myeloma cell-like morphology in the BM. A brain magnetic resonance imaging scan was performed; evidence from the previously performed oligodendroglioma resection was observed on the scan, but there were no significant findings, which made the diagnosis particularly challenging. The patient exhibited no response to the multiple combination therapies administered targeting MM and oligodendroglioma, and subsequently developed epilepsy and pneumonia, prior to succumbing to multiple organ failure. Among the various tumor types involving the central nervous system, oligodendroglioma is the least likely to metastasize; thus, distant metastases from brain oligodendrogliomas are extremely rare. To the best of our knowledge, this is the first case of metastatic oligodendroglioma presenting with typical MM-like symptoms and without any recurrence in the brain. PMID:27347150

    Summary Development of life-threatening cancer metastases at distant organs requires disseminated tumor cells’ adaptation to and co-evolution with the drastically different microenvironments of metastatic sites1. Cancer cells of common origin manifest distinct gene expression patterns after metastasizing to different organs2. Clearly, the dynamic interplay between metastatic tumor cells and extrinsic signals at individual metastatic organ sites critically impacts the subsequent metastatic outgrowth3,4. Yet, it is unclear when and how disseminated tumor cells acquire the essential traits from the microenvironment of metastatic organs that prime their subsequent outgrowth. Here we show that primary tumor cells with normal expression of PTEN, an important tumor suppressor, lose PTEN expression after dissemination to the brain, but not to other organs. PTEN level in PTEN-loss brain metastatic tumor cells is restored after leaving brain microenvironment. This brain microenvironment-dependent, reversible PTEN mRNA and protein down-regulation is epigenetically regulated by microRNAs (miRNAs) from astrocytes. Mechanistically, astrocyte-derived exosomes mediate an intercellular transfer of PTEN-targeting miRNAs to metastatic tumor cells, while astrocyte-specific depletion of PTEN-targeting miRNAs or blockade of astrocyte exosome secretion rescues the PTEN loss and suppresses brain metastasis in vivo. Furthermore, this adaptive PTEN loss in brain metastatic tumor cells leads to an increased secretion of cytokine chemokine (C-C motif) ligand 2 (CCL2), which recruits Iba1+ myeloid cells that reciprocally enhance outgrowth of brain metastatic tumor cells via enhanced proliferation and reduced apoptosis. Our findings demonstrate a remarkable plasticity of PTEN expression in metastatic tumor cells in response to different organ microenvironments, underpinning an essential role of co-evolution between the metastatic cells and their microenvironment during the adaptive metastatic

    Background Hepatoblastoma is the most frequent liver tumor in children, but very rare in the adult and associated with an unfavorable prognosis. The diagnosis is always postoperative or post mortem and biopsy is not useful. Surgery is the only accepted treatment. Case presentation Our patient underwent surgery in the suspect of liver metastasis from a previous gastric cancer. Surgery consisted in left lobectomy with partial diaphragm resection and partial pericardiectomy for a pericardial lesion, found after the opening of the thorax. The diaphragm defect was corrected with a biological mesh. Results The histopathological examination indicated hepatoblastoma of the adult with pericardial metastases. The patient was asymptomatic and without recurrence after 21 months of follow up. Conclusion The hepatoblastoma of the adult is related to a poor prognosis with median survival time less than 5 months. Surgery is the only curative treatment, but in many cases tumor resection requires complex operations. Vascular and thoracic expertise could be useful in the management of hepatoblastoma.

    Brain metastases are a frequent complication of many systemic cancers and portend a poor prognosis. This retrospective analysis of health claims data compared survival, treatment and health care utilization and costs in patients with brain metastasis by primary tumor site. Adult commercial and Medicare Advantage enrollees newly diagnosed with brain metastasis in 01 Jan 2004 through 30 Apr 2010 were identified. Inclusion required at least 2 claims that identified the same primary cancer site prior to diagnosis of brain metastasis and no evidence of primary brain tumors. Health care utilization rates and costs were calculated at the patient level for each month of follow-up. Differences among primary cancer site cohorts were assessed by ANOVA (continuous variables), Chi square test (proportions) and the Poisson distribution (utilization rates). The primary cancer cohorts comprised 1,031 lung cancer, 93 melanoma and 395 female breast cancer patients. During the 6 months prior to brain metastasis diagnosis, 59 % of lung cancer patients had no evidence of lymph node involvement or other metastatic disease compared to 55 and 42 % of melanoma and breast cancer patients (P < 0.001). Survival after brain metastasis diagnosis was less than 3 months for 52, 43 and 39 % for lung cancer, breast cancer and melanoma, respectively (P < 0.001). Melanoma patients had the highest rate of inpatient stays and outpatient visits (P ≤ 0.003). Total monthly all-cause costs were: melanoma, $23,426; breast cancer $19,708; lung cancer, $17,007 (P = 0.003). Health care utilization and costs after brain metastasis diagnosis were substantial and differed by primary tumor site.

    Penis metastasis from prostate cancer is very rare, and its management varies from case to case as there are very few cases reported in the literature. We describe a patient with prostate cancer treated with radiotherapy and androgen deprivation therapy who presented with urethral bleeding as a symptom of anterior urethral metastasis during followup. We propose a way to manage this and review the literature. PMID:25161796

    Gastric metastasis is rare but it can be the initial symptom of cancer. The second leading cause of this type of metastasis is breast cancer. A lack of clinical signs and nonspecific side effects of the treatment of primary tumors can lead to the misdiagnosis of metastatic gastric cancer. Upper gastrointestinal endoscopy with biopsy and immunohistochemistry should be used for diagnosis. Treatment is palliative; it includes chemo, endocrine, and radiation therapies. Four patients with breast cancer and gastric metastasis were identified. All the patients tested positive for estrogen and progesterone receptors, and received chemotherapy and hormone therapy. One patient underwent surgery and two received radiation therapy. Patients with breast cancer and gastrointestinal symptoms should be investigated for gastric metastasis, given its morbidity and negative impact on quality of life. PMID:27746881

    The median survival time of breast cancer patients with brain metastasis is less than 6 months, and even a small metastatic lesion often causes severe neurological disabilities. Because of the location of metastatic lesions, a surgical approach is limited and most chemotherapeutic drugs are ineffective owing to the blood brain barrier (BBB). Despite this clinical importance, the molecular basis of the brain metastasis is poorly understood. In this study, we have isolated RNA from samples obtained from primary breast tumors and also from brain metastatic lesions followed by microRNA profiling analysis. Our results revealed that the miR-509 is highly expressed in the primary tumors, whereas the expression of this microRNA is significantly decreased in the brain metastatic lesions. MicroRNA target prediction and the analysis of cytokine array for the cells ectopically expressed with miR-509 demonstrated that this microRNA was capable of modulating the two genes essential for brain invasion, RhoC and TNF-α that affect the invasion of cancer cells and permeability of BBB, respectively. Importantly, high levels of TNF-α and RhoC-induced MMP9 were significantly correlated with brain metastasis-free survival of breast cancer patients. Furthermore, the results of our in vivo experiments indicate that miR-509 significantly suppressed the ability of cancer cells to metastasize to the brain. These findings suggest that miR-509 has a critical role in brain metastasis of breast cancer by modulating the RhoC-TNF-α network and that this miR-509 axis may represent a potential therapeutic target or serve as a prognostic tool for brain metastasis.

    Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic. Previously studies reported spinal metastasis, but we report a first case of synchronous symptomatic cerebellar and cervical spinal metastasis after resection of symptomatic thoracic spinal metastasis from temporal GBM without any recurrence of excision areas.

    Cervical cancer is the most frequent type of cancer in women in many developing countries. Squamous cell carcinoma of the cervix spreads principally by lymphatics and less commonly through blood vessels. The most frequent sites for those who develop distant metastasis include lungs (21%), lumbar and thoracic spine (16%), and para-aortic lymph nodes (7%). Metastasis to the kidney is extremely rare with <10 previously reported cases. We report a case of renal metastasis from squamous cell carcinoma of the cervix detected in end-stage kidney due to hydronephrosis. PMID:27499599

    Tumor-to-tumor metastasis (TTM) is a rare phenomenon. We present a case of an invasive ductal carcinoma (IDC) of the breast metastasizing to a clear cell renal cell carcinoma (RCC). Breast cancer (BC) metastasis to the RCC is rarely reported, especially in resected kidney tumor. In several cases reported, IDC was the exclusively histologic type of BC metastasized to RCC. It seems that the different molecular type of IDC doesn't affect the metastatic tendencies to RCC. TTM was an indicator of diffuse disease. For any patient with a history of breast cancer, especially with multi-organs metastasis, resection of kidney tumor should be carefully considered.

    Myxopapillary ependymoma is a benign slow-growing tumour, arising predominantly in the region of the filum terminale. It has been designated histologically as grade I neoplasm according to the 2007 WHO classification. Despite this benign character dissemination and metastasis along the cerebrospinal axis and metastasis to distant sites have occasionally been reported. There have been previously reported cases of drop metastasis from MPE, however in three of these cases the drop metastasis was diagnosed with concurrent primary spinal MPE. There has been only one previously published case of interval drop metastasis in a case of operated spinal MPE in literature. We hereby present the second case of interval drop metastasis in a case of conus MPE, with history of having undergone a subtotal resection and post operative adjuvant radiotherapy prior to second surgery. The patient presented months after the primary surgery with symptoms of cauda equina syndrome attributable to the drop metastasis. PMID:27757435

In this report, we discuss the case of a 15-year-old girl who initially presented with a histiocytic cerebral sarcoma that was treated with aggressive resection and chemotherapy. Three years later, the same patient developed increasing shortness of breath and was found to have a high-grade pleomorphic undifferentiated cardiac sarcoma that likely represents the primary tumour from which the cerebral lesion metastasised. This represents an extremely unique case; in 2010, a research group in Germany claimed the very first description of a true cardiac sarcoma with brain metastasis [1]. However, even as far back as 1960, there were three case reports [2] and more extensive sarcoma studies recently have revealed further cases [3]. Nevertheless, there have probably been less than 10 cases in the literature up until this point. PMID:27594909

    Liver transplantation (LT) is the treatment of choice for localized hepatocellular carcinoma (HCC) associated with cirrhosis. Extra hepatic metastasis is the most common cause of death in these patients. There is very little evidence regarding the natural history and treatment options for patients developing HCC recurrence after LT. Surgical resection offers a unique opportunity for solitary metastasis. We report a 61 year old male with solitary right adrenal metastasis 15 months post LT which was managed with open adrenalectomy. The patient is alive and disease free 24 months after the surgery.

Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to external beam radiation therapy with cobalt 60 beams in a dose of 44 Gy followed by a 16 Gy boost. The patient is under followup and is presently asymptomatic. This paper adds to the repertoire of evidence in treatment of endotracheal metastasis.

    2015-12-01

    Anaplastic lymphoma kinase (ALK) has been identified to exert a potent transforming activity through its rearrangement in non-small cell lung cancer (NSCLC), and patients (pts) with ALK rearrangement can be treated more successfully with ALK inhibitors, such as crizotinib, alectinib, and ceritinib, than with chemotherapy. Despite the excellent efficacy of ALK inhibitors, resistance to these drugs is inevitably encountered in most ALK-rearranged pts. Cases of resistance are subtyped into three groups, i.e., systemic, oligo, and central nervous system (CNS) types, with the CNS being used to be considered a sanctuary. With regard to the management of CNS lesions in pts with ALK+ NSCLC, a growing body of evidence has gradually demonstrated the intracranial (IC) efficacy of ALK inhibitor (ALKi) in ALK+ NSCLC pts with brain metastases (BMs). Although the efficacy of crizotinib for the CNS lesions remains controversial, a recent retrospective investigation of ALK+ pts with BM enrolled in PROFILE 1005 and PROFILE 1007 demonstrated that crizotinib is associated with a high disease control rate for BM. However, BM comprises the most common site of progressive disease in pts with or without baseline BMs, which is a serious problem for crizotinib. Furthermore, alectinib can be used to achieve strong and long-lasting inhibitory effects on BM. In addition to alectinib, the IC efficacy of other next-generation ALK inhibitors, such as ceritinib, AP26113 and PF-06463922, has been demonstrated. In this article, we review the latest evidence regarding the BM and IC efficacy of ALK inhibitors in pts with ALK+ NSCLC.

    Brain metastasis is a major cause of morbidity and mortality in patients with breast cancer. Our previous studies indicated that Stat3 plays an important role in brain metastasis. Here, we present evidence that Stat3 functions at the level of the microenvironment of brain metastases. Stat3 controlled constitutive and inducible VEGFR2 expression in tumor-associated brain endothelial cells. Furthermore, inhibition of Stat3 by WP1066 decreased the incidence of brain metastases and increased survival in a preclinical model of breast cancer brain metastasis. WP1066 inhibited Stat3 activation in tumor-associated endothelial cells, reducing their infiltration and angiogenesis. WP1066 also inhibited breast cancer cell invasion. Our results indicate that WP1066 can inhibit tumor angiogenesis and brain metastasis mediated by Stat3 in endothelial and tumor cells.

    A retrospective analysis was done of 106 patients who received radiation therapy for brain metastasis. Dexamethasone therapy was instituted in 97 patients. Peptic ulcer disease developed in 5 of 89 patients (5.6 percent) who received a dosage of at least 12 mg a day, but did not occur in patients who received a lower dose or in those who did not receive steroids. The interval between institution of dexamethasone therapy and the development of peptic ulcer disease ranged from three to nine weeks. Two patients had perforated ulcers, one of whom required surgical resection. Peptic ulcer disease contributed to the general deterioration and death of three of the five patients. Overall, in 14 of the 89 patients (15.7 percent) a complication of steroid therapy developed in the form of peptic ulcer disease, steroid myopathy or diabetes mellitus (or a combination of these).

    Renal cell carcinoma accounts for 3% of all adult malignant tumors. Common sites of metastases are lungs, bone, liver, brain and adrenal glands. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60%-75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0-7%. A case is presented of a female patient diagnosed with renal cell carcinoma metastases to the paranasal sinuses, diagnosed and treated at the Department of ENT and Head and Neck Surgery, Zadar General Hospital, Zadar, Croatia. The tumor was surgically removed. Unfortunately, the patient died one year after the procedure due to multiorgan failure. Although metastases of renal cell carcinoma to the head and neck are very rare, it should be first suspected when investigating a metastatic tumor in this region. Surgical excision offers the best hope for long term survival. In case of unresectable tumor, other treatment options should be considered such as radiotherapy, immunotherapy and chemotherapy.

    Brain metastases develop in one-third of patients with non-small-cell lung cancer and are associated with a dismal prognosis, irrespective of surgery or chemo-radiotherapy. Pathological markers for predicting outcomes after surgical resection and radiotherapy responsiveness are still lacking. Caveolin 1 has been associated with chemo- and radioresistance in various tumors, including non-small-cell lung cancer. Here, caveolin 1 expression was assessed in a series of 69 brain metastases from non-small-cell lung cancer and matched primary tumors to determine its role in predicting survival and radiotherapy responsiveness. Only caveolin 1 expression in brain metastasis was associated with poor prognosis and an increased risk of death (log rank test, p = 0.015). Moreover, in the younger patients (median age of <54 years), caveolin 1 expression neutralized the favorable effect of young age on survival compared with the older patients. Among the radiotherapy-treated patients, an increased risk of death was detected in the group with caveolin 1-positive brain metastasis (14 out of 22 patients, HR=6.839, 95% CI 1.849 to 25.301, Wald test p = 0.004). Overall, caveolin 1 expression in brain metastasis from non-small-cell lung cancer is independently predictive of worse outcome and radioresistance and could become an additional tool for personalized therapy in the critical subset of brain-metastatic non-small-cell lung cancer patients.

    Lung cancer is one of the most common cancers in America. Frequent sites of metastasis include the Hilar lymph nodes, adrenal glands, liver, brain, and bone. The following case report is of a primary lung cancer with metastases to the breast and skin. Case. A 48-year-old African American male with a past medical history of poorly differentiated left breast cancer status after modified radical mastectomy (MRM), chronic obstructive pulmonary disease, and smoking (20 pack-years) presents to the ER with progressive shortness of breath on exertion, upper back pain, and weight loss for 2 months in duration. On physical examination he is found to have a MRM scar on his left breast and a left periumbilical cutaneous mass. Chest X-ray and chest CT reveal a right upper lobe mass and biopsies from the breast, lung, and the periumbilical mass indicate a poorly differentiated carcinoma of unclear etiology; all tumor markers are negative. The patient is male and a chronic smoker; therefore the diagnosis is made as lung carcinoma with metastases to the breast and skin. Conclusion. A high index of suspicion for cutaneous metastases should be cast when investigating cutaneous pathologies in patients at risk for primary lung malignancy. PMID:25861506

    Patient: Female, 60 Final Diagnosis: Gastroesophageal carcinoma with rectal metastasis Symptoms: Bloating • constipation • weight loss Medication: — Clinical Procedure: Endoscopy • flexible sigmoidoscopy • lower endoscopic ultrasound Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. Case Report: A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. Conclusions: Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Intraocular metastatic tumors have been increasingly reported in the recent past. Unlike choroidal metastasis, metastasis to retina is very rare and so far has been reported in very few case reports only. A 56 year-old male who presented with a history of adenocarcinoma of the cecum and underwent lap colectomy for the primary cecal tumor, received adjuvant chemotherapy for a year after surgery and decided to stop. He was also diagnosed with metastasis to liver and lung at this time. He presented with left eye pain, pressure and decreased vision suspicious for retinal metastasis from cecal primary lesion, 2 years after initial diagnosis. A mass of 5 x 10 mm was found on ophthalmoscopic examination and on ultrasound of the eye, in spite of normal results of MRI of the orbit. Palliative radiation therapy of the left eye resulted in decreased eye pressure and improved vision. As retinal metastasis carries a poorer prognosis due to higher risk of spread to central nervous system, the diagnosis of retinal metastasis in case of gastrointestinal cancers patients who present with vision changes should be made urgently. These patients should be thoroughly investigated with a synergistic approach of opthalmoscopic examination, ultrasound of the eye along with other imaging modalities like MRI of the orbit and just not MRI of orbit. Immediate action in the form of surgical or radiation treatments of the metastatic tumors of the eye should be instituted early on for a better prognosis. PMID:27489594

    Thyroid metastasis is atypical. We present a 70-year-old female case that was first diagnosed as gastric cancer after surgical approach. Two years later a thyroidectomy was performed and the immunohistochemistry (IHC) profile revealed a neuroendocrine tumor (NET): poorly differentiated neuroendocrine carcinoma (with small cells), with positive reaction for SYN, CROMO, negative for calcitonin, TTF1 and thyreoglobulin. The Ki-67 index was 25%. Considering the unusual metastasis, the IHC exam of the stomach tumor was performed pointing the same features as the thyroid findings. This proved that the thyroid tumor was a metastasis from a primary gastric neoplasia. This is an unusual case of NET because of the thyroid involvement. Nevertheless, the IHC exam played the major role in elucidating the diagnosis and the prognosis of the case. PMID:21424054

    This study proposes an umbrella deployment of swarm intelligence algorithm, such as stochastic diffusion search for medical imaging applications. After summarising the results of some previous works which shows how the algorithm assists in the identification of metastasis in bone scans and microcalcifications on mammographs, for the first time, the use of the algorithm in assessing the CT images of the aorta is demonstrated along with its performance in detecting the nasogastric tube in chest X-ray. The swarm intelligence algorithm presented in this study is adapted to address these particular tasks and its functionality is investigated by running the swarms on sample CT images and X-rays whose status have been determined by senior radiologists. In addition, a hybrid swarm intelligence-learning vector quantisation (LVQ) approach is proposed in the context of magnetic resonance (MR) brain image segmentation. The particle swarm optimisation is used to train the LVQ which eliminates the iteration-dependent nature of LVQ. The proposed methodology is used to detect the tumour regions in the abnormal MR brain images. PMID:26577158

    High affinity folate receptor (HFR) can be overexpressed in breast cancer and is associated with poor prognosis, however the expression in breast cancer brain metastases (BCBM) is unknown. The aim of this study was to analyze the rate of HFR expression in BCBM and its role in the prognosis of this high-risk cohort. We analyzed 19 brain metastasis (BM) and 13 primary tumors (PT) from a total of 25 patients. HFR status was assessed by immunohistochemistry. Median follow-up was 4.2 years (range 0.6-18.5). HFR was positive in 4/19 BM (21.1%) and in 1/13 PT (7.7%). Positive samples had low H-scores (range 1-50). 56% of patients had apocrine differentiation. OS was similar between patients with positive HFR (median OS 48 months) and negative HFR (median OS 69 months) (P = 0.25); and between patients with apocrine differentiation (median OS 63 months) and those without apocrine differentiation (median OS 69 months) (P = 0.49). To the best of our knowledge, this is the first analysis of HFR expression in BCBM. While previous studies associated the presence of HFR with worse prognosis; in our cohort HFR was positive in only 21.1% of BM with low levels of positivity. Neither HFR nor apocrine features had impact in OS.

    Chondroblastoma is a benign bone tumor with a relatively high incidence in older children and adolescents. Although it is generally regarded as a benign neoplasm, it sometimes grows aggressively or recurs but rarely metastasizes to the lung. We herein present a very rare case of a bilateral pneumothorax due to a pulmonary metastasis from a chondroblastoma. A 21-year-old man developed a bilateral pneumothorax 20 months after an operation for a chondroblastoma of the right ischium. A pertinent literature review revealed similar cases of chondroblastoma with pulmonary metastasis, but revealed no reports of a pneumothorax caused by a metastatic chondroblastoma.

    Ovarian metastasis of colorectal cancer is relatively rare. The present study reports two cases of synchronous ovarian metastasis from colorectal cancer, which were managed by cytoreductive surgery. In case one, a 60-year-old female patient presented with a multilocular pelvic tumor and ascites. Virtual colonoscopy revealed a mass in the sigmoid colon; however, no tumor cells were identified on histological examination. Ovarian metastasis from sigmoid colon cancer was suspected and adnexectomy was subsequently performed. Histological examination of the excised tumor revealed adenocarcinoma. Immunohistochemical analysis of the resected tumor revealed positive staining for cytokeratin (CK)20 and caudal-type homeobox 2 (CDX2), and negative staining for CK7, estrogen receptor, progesterone receptor and inhibin. The immunohistological results supported the diagnosis of ovarian metastasis from sigmoid colon cancer. In case two, a 56-year-old female patient presented with a multilocular pelvic tumor and ascites. Colonoscopy identified a rectal tumor, and histological examination revealed moderately-differentiated adenocarcinoma, which was confirmed by cytological analysis of ascites. Subsequently, ovarian metastasis from rectal cancer with peritoneal dissemination was diagnosed, and left ovariectomy and transverse colostomy were performed. Histological examination of the excised tumor revealed moderately-differentiated adenocarcinoma, and immunohistochemical investigation revealed positive staining for CK20 and CDX2, but negative staining for CK7. These immunohistological results indicated ovarian metastasis from rectal cancer. Both patients recovered well and are currently undergoing regular follow-up examinations. The observations from the two cases indicate that ovarian metastases of primary colorectal cancer may present as pelvic tumors and, thus, preoperative examination of the gastrointestinal tract is required. Furthermore, even in cases of widespread colorectal

    A morphological change resembling liver cirrhosis called pseudocirrhosis may be observed following chemotherapy for liver metastasis of breast cancer. Pseudocirrhosis is hypothesized to be caused by retraction of the hepatic capsule along with tumor shrinkage and subsequent scar formation around the metastatic lesion, as a response to the infiltrating tumor or chemotherapy-induced hepatic injury. The progression of cirrhotic changes may result in portal hypertension and esophageal varices. We managed two cases of esophageal variceal rupture during chemotherapy for breast cancer with liver metastasis. Hemostasis was successfully achieved by the endoscopic variceal ligation technique in both cases. We conclude that clinicians should be aware of the risk of pseudocirrhosis during chemotherapy for liver metastasis, and a periodic endoscopic follow-up is recommended along with appropriate management of esophageal varices.

    BACKGROUND Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. CASE REPORT A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. CONCLUSIONS Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Purpose We performed a multi-institutional study to identify prognostic factors and determine outcomes for patients with ALK-rearranged non–small-cell lung cancer (NSCLC) and brain metastasis. Patients and Methods A total of 90 patients with brain metastases from ALK-rearranged NSCLC were identified from six institutions; 84 of 90 patients received radiotherapy to the brain (stereotactic radiosurgery [SRS] or whole-brain radiotherapy [WBRT]), and 86 of 90 received tyrosine kinase inhibitor (TKI) therapy. Estimates for overall (OS) and intracranial progression-free survival were determined and clinical prognostic factors were identified by Cox proportional hazards modeling. Results Median OS after development of brain metastases was 49.5 months (95% CI, 29.0 months to not reached), and median intracranial progression-free survival was 11.9 months (95% CI, 10.1 to 18.2 months). Forty-five percent of patients with follow-up had progressive brain metastases at death, and repeated interventions for brain metastases were common. Absence of extracranial metastases, Karnofsky performance score ≥ 90, and no history of TKIs before development of brain metastases were associated with improved survival (P = .003, < .001, and < .001, respectively), whereas a single brain metastasis or initial treatment with SRS versus WBRT were not (P = .633 and .666, respectively). Prognostic factors significant by multivariable analysis were used to describe four patient groups with 2-year OS estimates of 33%, 59%, 76%, and 100%, respectively (P < .001). Conclusion Patients with brain metastases from ALK-rearranged NSCLC treated with radiotherapy (SRS and/or WBRT) and TKIs have prolonged survival, suggesting that interventions to control intracranial disease are critical. The refinement of prognosis for this molecular subtype of NSCLC identifies a population of patients likely to benefit from first-line SRS, close CNS observation, and treatment of emergent CNS disease.

    Case 1: A 61-year-old man who had a diagnosis of low rectal cancer with lateral pelvic lymph node (LPLN) metastasis and multiple liver metastases underwent low anterior resection with LPLN dissection. The initial surgery was followed by chemotherapy, and then an extended right hepatectomy with partial resection of the liver was performed. Subsequently, a lung metastasis was detected, and the lung was partially resected. The patient was alive 9 years and 6 months after the initial operation. Case 2: A 53-year-old man had a diagnosis of low rectal cancer. After 5 courses of mFOLFOX6 plus bevacizumab, he underwent low anterior resection with LPLN dissection and resection of the peritoneal metastasis. The patient was alive 6 years and 3 months after the surgery without any signs of recurrence. Case 3: A 48-year-old man had a diagnosis of low rectal cancer and multiple liver metastases. He underwent low anterior resection with LPLN dissection and right hepatic lobectomy. He subsequently showed liver and lung metastases. The patient received systemic chemotherapy, and is alive with recurrent disease. We report 3 cases of Stage Ⅳ low rectal cancer with LPLN metastasis, and propose that LPLN dissection is important as a part of R0 resection for Stage Ⅳ low rectal cancer. PMID:26805345

    Introduction: The maxillofacial region can harbour a wide range of primary tumours, as well as secondary tumours spreading from distant sites. Rare, though nevertheless important among the latter are genitourinary tumours, such as clear cell renal carcinoma and cervical cancer. Diagnosis of the maxillofacial metastasis sometimes precedes that of the original site, though in other cases the metastasis may arise many years after treatment of the primary tumour. Case report: We present three cases of maxillofacial metastasis of genitourinary tumours, two clear cell renal ade-nocarcinoma and squamous cell carcinoma of the uterine cervix. The patients were referred our hospital service for diagnosis and treatment, after having been initially evaluated for buccodental symptoms. Discussion: The appearance of a maxillofacial tumour, initially with the aspect of a primary tumour, may sometimes be the consequence of haematogenous dissemination from another site, such as these surprising cases originating in the genitourinary area. If disseminated metastatic disease is suspected, an extensive oncological screening should be done to evaluate the best therapeutic option in each patient. Key words: Maxillofacial metastasis, metastatic hypernephroma, cervical cancer. PMID:22143685

    This study analyzes the clinical characteristics of the brain metastasis (BM) of gynecologic cancer based on the type of cancer. In addition, the study examines the factors influencing the survival. Total 61 BM patients of gynecologic cancer were analyzed retrospectively from January 2000 to December 2012 in terms of clinical and radiological characteristics by using medical and radiological records from three university hospitals. There were 19 (31.1%) uterine cancers, 32 (52.5%) ovarian cancers, and 10 (16.4%) cervical cancers. The mean interval to BM was 25.4 months (21.6 months in ovarian cancer, 27.8 months in uterine cancer, and 33.1 months in cervical cancer). The mean survival from BM was 16.7 months (14.1 months in ovarian cancer, 23.3 months in uterine cancer, and 8.8 months in cervical cancer). According to a multivariate analysis of factors influencing survival, type of primary cancer, Karnofsky performance score, status of primary cancer, recursive partitioning analysis class, and treatment modality, particularly combined therapies, were significantly related to the overall survival. These results suggest that, in addition to traditional prognostic factors in BM, multiple treatment methods such as neurosurgery and combined chemoradiotherapy may play an important role in prolonging the survival for BM patients of gynecologic cancer.

    Brain metastasis (BM) in patients with breast cancer is a catastrophic event that results in poor prognosis. Identification of prognostic factors associated with breast cancer brain metastases (BCBM) could help to identify patients at risk. The aim of this study was to assess clinical characteristics, prognostic factors, and survival of patients with BCBM who had craniotomy and resection in a series of patients treated with modern multimodality therapy. We analyzed 42 patients with BCBM who underwent resection. Patients were diagnosed with breast cancer between April 1994 and May 2010. Cox proportional hazards regression was selected to describe factors associated with time to BM, survival from the date of first recurrence, and overall survival (OS). Median age was 51 years (range 24-74). Median follow-up was 4.2 years (range 0.6-18.5). The proportion of the biological subtypes of breast cancer was ER+/HER2- 25%, ER+/HER2+ 15%, ER-/HER2+ 30%, and ER-/HER2- 30%. Median OS from the date of primary diagnosis was 5.74 years. Median survival after diagnosis of BM was 1.33 years. In multivariate Cox regression analyses, stage was the only factor associated with shorter time to the development of BM (P = 0.033), whereas age was the only factor associated with survival from the date of recurrence (P = 0.027) and with OS (P = 0.037). Stage at primary diagnosis correlated with shorter time to the development of BM, while age at diagnosis was associated with shorter survival in BCBM. None of the other clinical factors had influence on survival.

    This is a case report on a giant cell tumor (GCT) in the proximal phalanx of the third finger of the left hand, with pulmonary metastasis. The patient presented pain in the finger without any previous history of trauma. Clinical examination, radiographic imaging and magnetic resonance imaging were carried out. A histological evaluation was carried out from an incisional biopsy, taking the hypothesis of GCT. The patient underwent amputation of the finger and the diagnosis was confirmed by means of microscopy on the specimen. The patient was followed up because of the risk of lung metastasis, which was shown by radiographic examination and computed tomography on the chest, and thoracotomy was performed. Since then, there has been an improvement in the symptoms that had been reported preoperatively, and no local recurrence or new metastasis has been found. PMID:27027012

    We reported the efficacy of concurrent chemoradiotherapy(CCRT)for cervical lymph node metastasis in patients with oropharyngeal or hypopharyngeal squamous cell carcinoma. The subjects were 17 patients with oropharyngeal or hypopharyngeal cancer with cervical lymph node metastasis, who underwent CCRT treatment between January 2005 and December 2009. The proportion of patients showing a complete response(CR)was 64. 7%; however, if patients without any residual viable cancer cells in the specimens obtained by neck dissection were also defined as CR, then, 82. 4% achieved CR. Thus, CCRT showed good efficacy without the need for planned neck dissection(PND). The limited recurrence cases and absence of serious complications associated with neck dissection after CCRT suggested that PND is not necessarily required. However, since assessment of cervical lymph nodes after CCRT is difficult, it would be desirable to develop a reliable examination and to study the most suitable examination for detecting the presence/absence of cervical lymph node metastasis.

    Prostate cancer is the second most common cancer in man. It commonly presents with urinary symptoms, bone pain, or diagnosed with elevated prostate-specific antigen.(PSA) levels. Correct staging and early diagnosis of recurrence by a precise imaging tool are the keys for optimum management. Molecular imaging of prostate cancer with Ga-68 prostate-specific membrane antigen.(PSMA), positron emission tomography-computed tomography.(PET-CT) has recently received significant attention and frequently used with a signature to prostate cancer-specific remark. However, this case will highlight the more cautious use of it.

Lymph node biopsy microscopic and immunohistochemistry examination revealed metastatic carcinoma favoring urothelial origin. Specificity of PSMA scan to prostate cancer has been seen to be compromised in a certain situation mostly due to neoangiogenesis, and false positives emerged in renal cell cancer, differentiated thyroid cancer, glioblastoma, breast cancer brain metastasis, and paravertebral schwannomas. Understanding the causes of false positive will further enhance the confidence of interpretating PSMA scans. PMID:27385897

    Contrast-enhanced radiotherapy is an innovative treatment that combines the selective accumulation of heavy elements in tumors with stereotactic irradiations using medium energy X-rays. The radiation dose enhancement depends on the absolute amount of iodine reached in the tumor and its time course. Quantitative, postinfusion iodine biodistribution and associated brain perfusion parameters were studied in human brain metastasis as key parameters for treatment feasibility and quality. Twelve patients received an intravenous bolus of iodinated contrast agent (CA) (40 mL, 4 mL/s), followed by a steady-state infusion (160 mL, 0.5 mL/s) to ensure stable intratumoral amounts of iodine during the treatment. Absolute iodine concentrations and quantitative perfusion maps were derived from 40 multislice dynamic computed tomography (CT) images of the brain. The postinfusion mean intratumoral iodine concentration (over 30 minutes) reached 1.94 ± 0.12 mg/mL. Reasonable correlations were obtained between these concentrations and the permeability surface area product and the cerebral blood volume. To our knowledge, this is the first quantitative study of CA biodistribution versus time in brain metastasis. The study shows that suitable and stable amounts of iodine can be reached for contrast-enhanced radiotherapy. Moreover, the associated perfusion measurements provide useful information for the patient recruitment and management processes.

    Background Skeletal metastasis is a common metastatic event for several carcinomas, and the treatment for skeletal metastasis of unknown primary (SMUP) are a critical issue in cancer therapy. Making a diagnosis of the primary site is the most crucial step in the treatment of SMUP; however, the procedures are sometimes difficult and time-consuming, and the primary site often remains unknown. Therefore, to establish optimal diagnostic strategies and elucidate the overall survival rates of SMUP, we conducted this retrospective study. Methods We retrospectively analyzed the clinical data for 286 SMUP cases from a total of 2,641 patients with skeletal metastases who were treated between 2002 and 2014 at our initiations. Results The primary sites were identified in 254/286 patients (88.8%), while 32 (11.2%) primary sites were not detected by our diagnostic strategies. Lung cancer was identified in 72 (25.2%) cases, and was the most frequently observed primary lesion. The median survival time of the SMUP patients was 20.0 months, while the median survival times of solitary bone metastasis cases and multi-bone metastasis cases were 39.0 months and 16.0 months, respectively. The median survival times of prostate cancer cases was over 120 months, that of patients with primary lung cancers was 9.0 months and the median survival time of cases who were finally diagnosed with an unknown primary was 11.0 months. Conclusions We believe that our study would contribute to establishing an optimal strategy for diagnosing the primary site in SMUP patients, and our data provide definite indications for the survival times for different SMUP situations.

    We experienced a case of pseudo-Meigs syndrome associated with metachronous metastasis to the ovary from ascending colon cancer. A 65-year-old woman underwent curative surgery for ascending colon cancer at another hospital. A follow-up CT carried out 3 months after the surgery revealed a right ovarian tumor and a large amount of ascites. The patient was diagnosed with ovarian metastasis from ascending colon cancer with carcinomatous peritonitis. Palliative care was recommended, and she presented at our department for a second opinion. In spite of a large amount of ascites and pleural effusion, no disseminating tumor was detected on contrast-enhanced CT at our hospital, and we recommended that she undergo a diagnostic laparotomy. The laparotomy was negative for carcinomatous peritonitis and a right oophorectomy was performed. The histopathological findings indicated that the ovarian tumor was consistent with metastasis from ascending colon cancer. After the surgery, we initiated chemotherapy with mFOLFOX6+bevacizumab and the symptoms were well controlled. A follow-up CT carried out 11 months after the surgery revealed a left ovarian tumor and increased ascites, and the patient underwent a left oophorectomy. Then, chemotherapy with the same regimen was administered for 12 months, and she did not develop any signs of recurrence for 27 months after the surgery. Ovarian metastasis from colon cancer may occasionally cause pseudo-Meigs syndrome, and it is important to be aware of the usefulness of oophorectomy for the control of ascites and pleural effusion.

A variety of extrathoracic tumors have a tendency to EBM especially breast, colon, and renal carcinomas are most frequent reported tumors however EBM of germ cell tumors are extremely rare. A 39-year-old and a 27-year-old male patient were admitted to our hospital with hemoptysis and dyspnea at different times. Both of them had a history of left orchiectomy due to mixed germ cell tumor two years and one year ago, respectively. On chest X-Ray and thorax computed tomography, first had a right upper lobe atelectasis and second had right total atelectasis. Fiberoptic bronchoscopy (FOB) performed and a vascularized endobronchial lesion (EBL) which tended to bleed was seen in the orifis of right upper lobe in the first case and right main bronchus was totally obstructed by EBL also in the second. Interventional bronchoscopy was performed via rigid bronchoscopy for biopsy and palliative treatment (argon plasma coagulation and debulking) in both two patients because of tendency to bleeding. A partial aperture was achieved at right upper lobe bronchus in the first case and total atelectasis resolved in the second case. Immunohistochemically, histopathological examinations of both patients biopsies confirmed EBM of mixed germ cell tumors. In conclusion, EBM of the germ cell tumors especially with total or partial atelectasis are extremely rare. We want to present these cases to emphasize the importance of distinguishing EBM from primary lung carcinoma which treatment and survival could be different. PMID:27481085

    Raman spectroscopy has become widely used for diagnostic purpose of breast, lung and brain cancers. This report introduced a new approach based on spatial frequency spectra analysis of the underlying tissue structure at different stages of brain tumor. Combined spatial frequency spectroscopy (SFS), Resonance Raman (RR) spectroscopic method is used to discriminate human brain metastasis of lung cancer from normal tissues for the first time. A total number of thirty-one label-free micrographic images of normal and metastatic brain cancer tissues obtained from a confocal micro- Raman spectroscopic system synchronously with examined RR spectra of the corresponding samples were collected from the identical site of tissue. The difference of the randomness of tissue structures between the micrograph images of metastatic brain tumor tissues and normal tissues can be recognized by analyzing spatial frequency. By fitting the distribution of the spatial frequency spectra of human brain tissues as a Gaussian function, the standard deviation, σ, can be obtained, which was used to generate a criterion to differentiate human brain cancerous tissues from the normal ones using Support Vector Machine (SVM) classifier. This SFS-SVM analysis on micrograph images presents good results with sensitivity (85%), specificity (75%) in comparison with gold standard reports of pathology and immunology. The dual-modal advantages of SFS combined with RR spectroscopy method may open a new way in the neuropathology applications.

    Intramedullary spinal cord metastases are very rare and usually associated with lung or breast cancer, with gastric origin being exceptional. Their clinical onset tends to be faster than that of primary intramedullary tumours. The most common early symptoms of intramedullary spinal cord metastasis are motor deficit in one or more limbs, pain, sensory loss, and sphincter disturbances. The appearance of a rapidly progressive Brown-Séquard syndrome in an oncology patient should orientate the diagnosis of this condition. The prognosis is very poor, with a median survival of 4 months. However, recent research has shown that surgery could offer a slight benefit in survival and functionality. The case is reported of a 61-year-old man with an intramedullary spinal cord metastasis from a gastric carcinoma, as well as a literature review of this topic. It has been found that this case is the fourth one reported in the literature.

    We report the first documented case of ovarian metastasis from a jejunal primary adenocarcinoma in an Australian patient. The presentation was unusual, initially a suspicious abdominal nodule in the epigastric area, which turned out to be an adenocarcinoma of possible intestinal origin. Gastroscopy and colonoscopy were performed with no suspicious lesion identified. Abdominal and pelvic ultrasound imaging showed a complex pelvic mass suspicious of ovarian cancer. Laparoscopy was performed to exclude possibility of ovarian cancer and small bowel cancer. The ovarian mass showed similar features from the epigastric nodule, again suggestive of intestinal primary. Definitive diagnosis was obtained when the patient represented 2 months later with malignant bowel obstruction requiring palliative resection of the proximal jejunum. This case demonstrates the difficulty in diagnosing ovarian metastasis from a small bowel primary, which has the potential to mimic an ovarian primary tumour clinically, and a large bowel or ovarian primary pathologically.

    Although prostate cancer is common in the western world and is associated with favorable overall survival, neuroendocrine prostate cancer is difficult to detect and is known to aggressively metastasize throughout the body. This subset of disease thus has a poor prognosis, and early detection and treatment of neuroendocrine prostate cancer may increase overall survival. We present a case of a now deceased 63 year old male with extensive epicardial, respiratory, hepato-bilary, adrenal, genitourinary, and osseous tissue metastasis. PMID:27489779

    Microcalcifications are frequently associated with papillary thyroid cancers. Metastatic nodules from extrathyroid malignancies may mimic primary thyroid neoplasm on sonography, but do not present with microcalcifications. We report the case of a 45-year-old woman with a history of invasive ductal carcinomas of bilateral breasts, status post surgery and neoadjuvant chemotherapy. Four years after surgery, thyroid sonography revealed diffuse microcalcifications without nodular component. Core needle biopsy confirmed thyroid metastasis from primary breast cancer. PMID:24752943

    Brain metastasis from triple-negative breast cancer (TNBC) has continued to lack effective clinical treatments until present. However, the feature of epidermal growth factor receptor (EGFR) frequently overexpressed in TNBC offers the opportunity to employ lapatinib, a dual-tyrosine kinase inhibitor of human epidermal growth factor receptor-2 (HER2) and EGFR, in the treatment of brain metastasis of TNBC. Unfortunately, the low oral bioavailability of lapatinib and drug efflux by blood-brain barrier have resulted in low drug delivery efficiency into the brain and limited therapeutic effects for patients with brain metastasis in clinical trials. To overcome such disadvantages, we developed lapatinib-loaded human serum albumin (HSA) nanoparticles, named LHNPs, by modified nanoparticle albumin-bound (Nab) technology. LHNPs had a core-shell structure and the new HSA/phosphatidylcholine sheath made LHNPs stable in bloodstream. Compared to free lapatinib, LHNPs could inhibit the adhesion, migration and invasion ability of high brain-metastatic 4T1 cells more effectively in vitro. Tissue distribution following intravenous administration revealed that LHNPs (i.v., 10 mg/kg) achieved increased delivery to the metastatic brain at 5.43 and 4.36 times the levels of Tykerb (p.o., 100 mg/kg) and lapatinib solution (LS, i.v., 10 mg/kg), respectively. Compared to the marketed Tykerb group, LHNPs had markedly better inhibition effects on brain micrometastasis and significantly extended the median survival time of 4T1 brain metastatic mice in consequence. The improved anti-tumor efficacy of LHNPs could be partly ascribed to down-regulating metastasis-related proteins. Therefore, these results clearly indicated that LHNPs could become a promising candidate for clinical applications against brain metastasis of TNBC. PMID:27086917

    The orbit is a frequent site of metastasis, particularly from the breast, prostate gland and the lung. Carcinoma of the cervix metastasizing to the orbit is rare. We report a 27-year-old woman with Stage II B cervical cancer who presented with progressive painless protrusion of the left eye of one month duration associated with diplopia. Histology of the orbital mass was similar to that of the cervical cancer and reported as squamous cell carcinoma. She received palliative radiation to the left orbit 30 Gy in 10 fractions along with chemotherapy (Paclitaxel and Carboplatin). This resulted in regression of the proptosis. We review published literature of cases of carcinoma of the uterine cervix with metastasis to the orbit. PMID:26894102

    Cachexia, a wasting syndrome associated with advanced cancer and metastasis, is rarely documented in breast cancer patients. However, the incidence of cachexia in breast cancer is now thought to be largely underestimated. In our case report of a breast cancer patient with bone metastasis monitored during the course of her treatment, we document the development of cachexia by image analysis in relation to her metastatic burden. Elucidation of the link between metastatic burden and cachexia could unveil a highly specific screening process for metastasis, by assessing true muscle mass loss. Our patient was a 49-year-old premenopausal woman, with metastatic invasive ductal breast carcinoma in the vertebral and iliac bones on presentation, which progressed with new metastases to her hips, thigh bones, and vertebrae. In the two-year period, that is between her diagnosis and death, she lost >10% of her baseline weight. During these two years, we retrospectively identified a decrease in paraspinal muscle (PM) at the third lumbar vertebra followed by a sharp decline in weight. The increased tumor burden over time in metastatic sites was accompanied by a decrease in abdominal muscle and visceral and subcutaneous fat and was followed by the patient's demise. The increasing tumor burden in the patient was correlated with the mass of other tissues to determine the tissue that could best serve as a surrogate marker to cachexia and tumor burden. We noted a strong negative correlation between PM area and metastatic tumor area at the third lumbar vertebral level, with PM loss correlating to increasing tumor burden. The monitoring of PM wasting may serve as a marker, and therefore a prognostic factor, for both cachexia and extent of metastatic disease, especially in breast cancer, where metastasis to bone is frequent. Based on our data and review of the literature in this case study, longitudinal monitoring of cachexia in the selected muscle groups can give clinicians early

    Differentiated thyroid carcinoma (DTC) is a common malignancy. The general treatments are thyroidectomy of the affected lobe along with lymphadenectomy. However, bone metastasis is rare in DTC compared with other malignancies and the management of metastasis foci is still controversial. Here we present a case of follicular thyroid carcinoma with the 6th cervical vertebra body metastasis successfully treated by total thyroidectomy, cervical corpectomy, and internal fixation, followed by hormone replacement therapy and radioiodine therapy. Eleven additional patients diagnosed as thyroid carcinoma with bone metastasis collected from Chinese literature between January 1996 and December 2013 were also reviewed. The mean age of the 12 patients at presentation was (53.9±9.2) years (rang, 42–72 years) and the male to female ratio was 1:2. Nine cases received total/near-total thyroidectomy or lobectomy while the other three patients refused for personal reasons. The interventions for bone metastasis were one-stage operation (9/12), I131 adjuvant therapy (3/12), chemotherapy (1/12), and no intervention (1/12). During the follow-up, two patients died of metastatic carcinoma recurrence, one died of multiple organ metastasis, and one with an unknown reason. We conclude that the management of thyroid carcinoma with bone metastasis needs multidisciplinary cooperation. Surgical resection is still the first choice for cure, while the combined one-stage operation on the primary and metastatic sites followed by hormone replacement therapy and radioiodine therapy is an applicable treatment.

    Thyroid cancer is usually, relatively hypofunctional; most patients with thyroid cancer are clinically euthyroid. The combination of thyroid cancer and thyrotoxicosis is not common. We herein, report a case of follicular thyroid cancer with hyperfunctioning metastasis in a 43-year-old woman who presented with thyrotoxicosis, a cold right thyroid nodule, and low I-131 uptake at the thyroid bed. An additional total body scan with I-131 revealed a large radioiodine avid osteolytic bone metastasis with soft tissue masses and liver metastasis. The patient received treatment with total thyroidectomy, methimazole, and I-131 at a cumulative dose of 600 mCi along with recombinant human thyroid-stimulating hormone before the first I-131 treatment and palliative radiation. The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment.

    Breast metastasis from extra-mammary malignancy is rare. An incidence of 0.4% to 1.3% has been reported in literature. The primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. In this report, two cases of pulmonary metastasis to the breast were presented. A 40-year-old female manifested a right breast mass of 2-month duration. After physical examination was performed, a poorly defined mass was noted in the upper outer quadrant of the right breast. Another 49-year-old female manifested right breast mass of 5-day duration. A poorly defined mass was noted in the lower inner quadrant of the right breast. Mammography results also revealed breast cancer. The patients underwent local excision. After histological and immunohistochemical analyses were conducted, a primary lung carcinoma that metastasized to the breast was diagnosed. An accurate differentiation of metastasis to the breast from primary breast cancer is very important because the treatment and prognosis of the two differ significantly. PMID:25364582

    We report on a 61-year-old woman with a history of right-sided nephrectomy for clear cell renal cell carcinoma (RCC) occurring 21 years ago; she currently presented with a bilateral ovarian tumour. Histologically, the tumour of both ovaries was clear cell carcinoma. Immunohistochemically, the tumour cells were positive for vimentin, RCC marker, epithelial membrane antigen, cytokeratin AE1/3 and CD10. Cytokeratin 7, CA125, HMWCK, estrogen and progesterone receptors were all negative. Based on the morphology and immunophenotype of the tumour, we established a diagnosis of late metastasis of RCC in the ovaries. A postoperative abdominal computed tomography scan, however, revealed a tumour mass solely in the left kidney, which had not been visible in the preoperative ultrasound. The patient underwent nephron-sparing surgery and a biopsy showed the tumour to be clear cell RCC. Metastasis of RCC to the ovaries is rare, and to the best of our knowledge, only 24 cases have been reported to date. However, due to the different treatments and prognosis, the distinction between a primary ovarian tumour and metastasis of RCC is important. PMID:24678363

    Metastasis of breast cancer is often detected through a long-term course and difficult to diagnose. We report a case of brachial plexopathy suspected to be the initial lesion of breast cancer metastasis, which was only detected by magnetic resonance (MR) neurography. A 61-year-old woman was admitted to our hospital within 2 years after operation for breast cancer because of progressive dysesthesia and motor weakness initially in the upper limb on the affected side and subsequently on the contralateral side. Enhanced computed tomography, axillary lymph node echo, gallium scintigraphy, and short tau inversion recovery MR images showed no abnormalities. MR neurography revealed a swollen region in the left brachial plexus. We suspected neuralgic amyotrophy and initiated treatment with intravenous immunoglobulin therapy and steroid therapy. However, there was no improvement, and the progression of motor weakness in the bilateral lower limbs appeared over 4 years. Concomitant elevation of carbohydrate antigen 15-3 level (58.9 U/ml) led us to suspect breast cancer metastasis, which was associated with the worsening of neurological findings, although gallium scintigraphy and bone scintigraphy showed no inflammatory and metastatic lesions. Swelling of the cauda equina in enhanced lumbar MR imaging and abnormal accumulation at the brachial plexus and cervical spinal cord in positron-emission tomography were newly detected contrary to the normal findings on the gallium scintigraphy, which suggested cerebrospinal fluid seeding. We suspected breast cancer metastasis about the initial brachial plexopathy based on the clinical course. MR neurography may be a helpful tool to detect metastatic lesion, especially in nerve roots.

    Brain metastases (BM) represent the most common tumor to affect the adult central nervous system. Despite the increasing incidence of BM, likely due to consistently improving treatment of primary cancers, BM remain severely understudied. In this study, we utilized patient-derived stem cell lines from lung-to-brain metastases to examine the regulatory role of STAT3 in brain metastasis initiating cells (BMICs). Annotation of our previously described BMIC regulatory genes with protein-protein interaction network mapping identified STAT3 as a novel protein interactor. STAT3 knockdown showed a reduction in BMIC self-renewal and migration, and decreased tumor size in vivo. Screening of BMIC lines with a library of STAT3 inhibitors identified one inhibitor to significantly reduce tumor formation. Meta-analysis identified the oncomir microRNA-21 (miR-21) as a target of STAT3 activity. Inhibition of miR-21 displayed similar reductions in BMIC self-renewal and migration as STAT3 knockdown. Knockdown of STAT3 also reduced expression of known downstream targets of miR-21. Our studies have thus identified STAT3 and miR-21 as cooperative regulators of stemness, migration and tumor initiation in lung-derived BM. Therefore, STAT3 represents a potential therapeutic target in the treatment of lung-to-brain metastases. PMID:26314961

    The breast is an extremely rare target organ for metastasis of extramammary neoplasms. The occurence varies between 1.7% to 6.6% in autopsies; between 1.2% and 2% in clinical cases; and around 2.7% in sputum series. In accordance with the primary tumor localization, it is more common to find metastases of lymphoma, melanoma, rhabdomyosarcoma, tumors of the lung and ovarian tumors. Breast metastasis of the uterine cervix is a very seldomly found. According to the published literature so far there have been around 30 documented cases with such pathology. This study presents the case of a 48-year-old female with a squamous cell carcinoma of the uterine cervix, which was histologically verified in 2010. Three years after the initial tumor diagnosis, radiotherapy and chemotherapy, the patient was found to have a cystic tumor formation in one of her breasts. The formation was painful to pressure. Quadrantectomy with an open bisopsy was performed to the patient. Histological and immunohistochemical diagnosis rejected primary squamous cell carcinoma of the breast. The differential diagnosis of metastatic lesions in the breast is problematic and requires careful clinical history, immunohistochemical study and multidisciplinary approach in the management. Mammary metastases are a bad predictor and they serve as an indicator of generalized dissemination of the primary tumor process.

    Background: Carcinoma of the thyroid gland is one of the most commonly encountered endocrine malignancies. Papillary carcinoma is the most common histological type, and its spread is usually lymphatic. About 30–80% patients with papillary carcinoma develop lymphatic metastases. Case Report: We present here the case of a 70-year-old female patient who had undergone total thyroidectomy 10 years previously, with a histological diagnosis of papillary thyroid carcinoma. A neck dissection was performed ten years after the primary operation due to a mass in the parapharyngeal space and hypopharynx. The mass was diagnosed histologically as papillary thyroid cancer metastasis after the operation. Conclusion: Lymphatic and vascular metastases of papillary thyroid carcinoma separately to the parapharyngeal space and hypopharynx have rarely been reported. In our case, both hypopharyngeal and parapharyngeal space involvement were presented, which is a very rare condition. PMID:25207192

A case of follicular carcinoma thyroid with orbital metastasis presenting as ophthalmomyiasis externa is reported. The patient presented with foul smelling ulcers of the medial and lateral orbital walls of the right eye extending into the lids and nose, teeming with maggots. Computerized Tomography (CT) showed widespread bone destruction with extension into surrounding sinuses. Over 200 maggots were manually removed after immobilisation with turpentine oil instillation. Entomological examination showed it to be a case of accidental myiasis caused by the common housefly Musca domestica. The patient was managed conservatively and the ulcer cavities filled up with healthy granulation tissue. This case is presented on account of its rarity.

    Reports of brain abscesses caused by medication-related osteonecrosis of the jaw (MRONJ) are very rare. We here present the case of a 76-year-old man with terminal-stage prostatic carcinoma and a brain abscess caused by MRONJ at the maxilla. The patient had been treated with zoledronic acid and denosumab for bone metastasis. For the brain abscess, an antibiotic regimen based on ceftriaxone and metronidazole and a sequestrectomy contributed to a successful outcome. In the case of maxillary MRONJ extending to the maxillary sinus, active resection of the infected bone should be considered to prevent the spread of the infection beyond the maxillary sinus, into the ethmoid sinus, and into the brain.

    Compression fracture of the vertebral body is common in the older patients. The possible etiology like osteoporosis or cancer metastasis should be included as a possibility in the differential diagnosis for severe back pain, to prevent delays in diagnosis and treatment. More severe fractures can cause significant pain, leading to inability to perform activities of daily living, and life-threatening in the older patient.We report a rare case of a 61-year-old man suffering from severe lower back pain and intermittent abdominal fullness. He came to our clinic, where muscle power was normal, but could not stand up or change posture because of severe back pain. Plain film and magnetic resonance imaging of lumbar spine both revealed osteoblastic lesion at L2 spine. Abdomen computed tomography showed a mass at the pancreatic body. The pancreatic cancer with osteoblastic metastasis was diagnosed. After receiving multimodality therapy such as percutaneous vertebroplasty and pain controlling, we provided effective palliation of symptoms, aggressive rehabilitation program, and better quality of life.Our case highlights the benefits of multidisciplinary cancer treatment for such patient, preventing the complications such as immobilization accompanied with adverse effects like musculoskeletal, respiratory, and cardiovascular systems. All clinicians should be informed of the clinical findings to provide patients with suitable therapies and surveys.

    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

    To explore the correlation between epidermal growth factor receptor (EGFR) mutation status and the risk of brain metastasis (BM) in patients with lung adenocarcinoma, the clinical data of 100 patients with pathologically confirmed lung adenocarcinoma and known EGFR mutation status at exon 18, 19, 20, or 21 were analyzed retrospectively. The incidence of BM was similar between patients with wild-type EGFR and those with EGFR mutations (p = 0.48). However, among patients with EGFR mutations, the incidence of BM was significantly higher in patients with mutation at exon 19 than in patients with mutation at other sites (p = 0.007). Besides, among patients with heterochronous BM, 66.7 % had EGFR mutations. Regarding brain-metastasis-free survival (BMFS), patients with EGFR sensitive mutations (mutation at exon 19/21/and dual mutation) had significantly shorter BMFS compared with patients with wild-type EGFR (p = 0.018). For patients treated only with chemotherapy, BM was an unfavorable prognostic factor. Patients with BM had worse overall survival compared with those without BM (p = 0.035). However, in patients with BM and EGFR sensitive mutations, those treated with tyrosine kinase inhibitors (TKIs) had significantly longer overall survival compared with those treated with chemotherapy only (p = 0.0081). In conclusion, among patients with EGFR mutations, those mutated at exon 19 had the highest incidence of BM. Furthermore, patients with EGFR mutations are more likely to develop heterochronous BM. The BMFS was significantly shorter in patients with EGFR sensitive mutations. TKIs improved the survival of patients with lung adenocarcinoma and BM who harbored EGFR sensitive mutations.

    2016-01-01

    Background: Description of three cases of metastatic esophageal carcinoma to the iris and focus on management strategies. Methods: A 48-year-old man (Case 1) with previously treated stage IV esophageal carcinoma presented with blurred vision in the left eye (OS) for 3 weeks. Initial fine needle aspiration biopsy (FNAB) was negative for malignant cells, so incisional biopsy was performed and confirmed metastatic carcinoma. A 53-year-old man (Case 2) with previously treated stage III esophageal cancer experienced 2 months of pain and 1 month of blurred vision OS. Documented tumor growth suggested esophageal carcinoma metastasis. A 65-year-old man (Case 3) with previously treated stage IV esophageal carcinoma developed hyphema in the right eye (OD), and FNAB confirmed metastatic carcinoma. Results: Case 1 was treated with external beam radiotherapy (EBRT), delivered over 16 days which resulted in complete tumor regression. Case 2 received stereotactic body radiotherapy (SBRT) over 21 days leading to complete tumor regression. Case 3 was treated with plaque radiotherapy over 4 days, resulting in complete tumor regression. Conclusions: In all three cases, radiotherapy was employed, and enucleation was avoided. Plaque radiotherapy achieved tumor control in a shorter period of time (4 days) compared to EBRT (16 days) or SBRT (21 days). Knowing the short life expectancy of these patients, plaque radiotherapy appears most favorable. PMID:27433035

    Palliative radiotherapy (PRT) is useful in the management of many patients with brain metastases, but the need for this treatment in the general cancer population is unknown. The objective of this study was to estimate the appropriate rate of use of PRT for brain metastases (PRT.Br). Ontario's population-based cancer registry was used to identify patients who died of cancer. Radiotherapy records from all the province's radiotherapy centres were linked to Ontario's cancer registry to identify patients who received PRT.Br in the last 2 years of life. Multivariate analysis was used to identify social and health system-related barriers to the use of PRT.Br and to identify a subpopulation of patients with unimpeded access to PRT.Br. The rate of use of PRT.Br was measured in this benchmark subpopulation. The benchmark rate was standardised to the case mix of the overall cancer population. The study population included 231,397 patients who died of cancer in Ontario between 1998 and 2007. Overall, 13,944 patients received at least one course of PRT.Br in the last 2 years of life (6.0%). Multivariate analysis showed that the use of PRT.Br was strongly associated with: the availability of radiotherapy at the diagnosing hospital; the socioeconomic status of the community where the patient lived; and the distance from his/her home to the nearest radiotherapy centre. The benchmark subpopulation was defined as patients diagnosed in a hospital with radiotherapy facilities on site and who resided in a high income community, within 50 km of the nearest radiotherapy centre. The standardised benchmark rate of PRT.Br was 8.0% (95% confidence interval 7.5%, 8.5%). The overall shortfall between the actual rate and the benchmark was 25%, but varied by primary cancer site: lung, 27.6%; melanoma, 19.4%; breast, 13.9%. The magnitude of the shortfall in the use of PRT.Br varied widely across the province. At least 8.0% of patients who die of cancer require PRT.Br at least once in the last 2

    Mutations on epidermal growth factor receptor (EGFR) of adenocarcinomas of lung have been found to be associated with increased sensitivity to EGFR tyrosine kinase inhibitors and K-ras mutations may correlate with primary resistance. We aimed to explore the discordant mutation statuses of EGFR and K-ras between primary tumors and matched brain metastases in adenocarcinomas of lung. We used a sensitive Scorpion ARMS method to analyze EGFR mutation, and Sanger sequencing followed by allele-specific real-time polymerase chain reaction to analyze K-ras mutation. Forty-nine paired tissues with both primary adenocarcinoma of lung and matched brain metastasis were collected. Thirteen patients (26.5%) were discordant for the status of EGFR between primary and metastatic sites. K-ras gene could be checked in paired specimens from 33 patients, thirteen patients (39.6%) were discordant for the status of K-ras. In primary lung adenocarcinoma, there were 14 patients of mutant EGFR had mutant K-ras synchronously. This study revealed that the status of EGFR mutation in lung adenocarcinomas is relatively consistent between primary and metastatic sites compared to K-ras mutation. However, there are still a few cases of adenocarcinoma of lung showing discordance for the status of EGFR mutation. Repeated analysis of EGFR mutation is highly recommended if tissue from metastatic or recurrent site is available for the evaluation of target therapy. PMID:27070580

    Intramedullary spinal cord metastases (ISCMs) are rare and account for 4-8.5% of central nervous system metastases. Only one case of biopsy-proven ISCM due to prostate cancer has previously been reported. The current study presents an additional unique case of a 74-year-old male who developed symptoms from an intramedullary conus medullaris metastasis as the first manifestation of prostate adenocarcinoma. To the best of our knowledge, this scenario is even more rare and has not previously been reported. The tumor was radically resected, followed by androgen blockade treatment. The patient's neurological deficit significantly improved, with no tumor recurrence during the follow-up period. In addition, the present study provides an overview of the previous literature concerning ISCMs from prostate cancer, and discusses the treatment options.

    Purpose: Data comparing the clinical outcomes of local brain radiotherapy (LBRT) and whole brain RT (WBRT) in patients with a single brain metastasis after tumor removal are limited. Patients and Methods: A retrospective analysis was performed to compare the patterns of treatment failure, cause of death, progression-free survival, median survival time, and Karnofsky performance status for long-term survivors among patients who underwent surgery followed by either LBRT or WBRT between 1990 and 2008 at the National Cancer Center Hospital. Results: A total of 130 consecutive patients were identified. The median progression-free survival period among the patients who received postoperative LBRT (n = 64) and WBRT (n = 66) was 9.7 and 11.5 months, respectively (p = .75). The local recurrence rates (LBRT, 9.4% vs. WBRT, 12.1%) and intracranial new metastasis rate (LBRT, 42.2% vs. WBRT, 33.3%) were similar in each arm. The incidence of leptomeningeal metastasis was also equivalent (LBRT, 9.4% vs. WBRT, 10.6%). The median survival time for the LBRT and WBRT patients was 13.9 and 16.7 months, respectively (p = .88). A neurologic cause of death was noted in 35.6% of the patients in the LBRT group and 36.7% of the WBRT group (p = .99). The Karnofsky performance status at 2 years was comparable between the two groups. Conclusions: The clinical outcomes of LBRT and WBRT were similar. A prospective evaluation is warranted.

    Background. The parotid gland is an unusual site for metastatic disease and when metastasis occurs, it commonly originates from head and neck primaries. Spread from distant infraclavicular sites such as the breast, into the parotid, is even more unusual with very few cases reported in the literature. Case Report. We describe the case of a 65-year-old woman presenting for a rapidly enlarging right parotid mass. She had a history of an invasive ductal carcinoma of the right breast and was disease-free in the past 6 years prior to her presentation. She was thereafter diagnosed as having a solitary parotid metastasis from breast origin. A total parotidectomy was done and she was referred for adjuvant radiotherapy. Conclusion. Any parotid metastasis should be investigated, especially in patients with a prior history of cancer where the possibility of metastasis, even if improbable, should be kept in mind. Fine needle aspiration biopsy (FNAB) is the first diagnostic procedure to be done and immunocytochemistry can provide valuable information even if it is not always needed for diagnosis. Superficial parotidectomy when feasible with adjuvant radiotherapy is the preferred approach for solitary metastasis of the parotid. The prognosis, however, remains poor regardless of the treatment modality used. PMID:26942028

    A 78-year-old man was admitted for workup for a liver tumor. Both serum AFP and PIVKA-II levels were high (2260ng/ml and 806mAU/ml, respectively). Contrast-enhanced CT scan and MRI using Gd-EOB-DTPA demonstrated a liver tumor in segment 6 resembling the imaging patterns of hepatocellular carcinoma (HCC), while the upper gastrointestinal endoscopy revealed a type 2 gastric cancer in the gastric antrum. Although the liver metastasis of the gastric cancer was undeniable, we performed partial resection of segment 6 of the liver and distal gastrectomy under a preoperative diagnosis of double cancer. Histopathologically, gastric tumor consisted of two components, such as well differentiated adenocarcinoma and hepatoid adenocarcinoma. The histology of the liver tumor was similar to that of the hepatoid component in the stomach lesion. Immunohistochemical staining revealed both the gastric and the liver tumors to be positive for AFP and PIVKA-II, yielding a definite diagnosis of AFP and PIVKA-II producing gastric cancer with liver metastasis. Because many cases of this disease have liver metastases at presentation with confusing images with HCC, the diagnosis of liver tumors should be carefully differentiated in the gastric cancer patients with liver tumors, high serum AFP and PIVKA-II levels.

    Angiosarcoma has been reported as a rare case, having high potential of hematogeneous lung metastasis and then developing to pneumothorax with ease. The patient was a 74-year-old man afflicted with a malignant hemangio endothelioma (MHE) of the scalp. His MHE of the scalp was resected and skin grafting was made, then, he was administered docetaxel hydrate intravenously as adjuvant setting. Three years after, he complainted left chest pain and dyspnea, so his chest Xp was checked up and showed left pneumothorax. Chest computed tomography revealed multiple thin walled cavities of right and left lung and bullae with slightly thick walled cavity at apex legion of the left lung. We resected bullae with tumor of the left apex legion under video assisted thoracic surgery. After operation, He was administerd ricombinant interleukin-2 intravenously in order to control lung metastasis of the scalp, but his condition deteriorated and 6 months after pneumothorax he died. The average survival time from the 1st pneumothorax episode was only 4.7 months. He kept a good activities of daily living without reccurrence of pneumothorax by operation, so we thought that the operaion for pneumothorax with MHE was one option for therapy.

    There are few reports of large cell neuroendocrine carcinoma (LCNEC) metastasis to the head and neck region, and no cases reporting LCNEC from lung metastasizing to the mandible. LCNEC is not well reported in the literature due to recent changes in the criteria for diagnosis, revised in 2004 by the world health organization, due to its propensity for rapid growth and low 5 year prognosis. We present a 61 year old female diagnosed with LCNEC of the lung in October, 2007 treated with radiation and chemotherapy. Our patient had a PET scan performed in March, 2009 revealing no sign of metastasis. In July, 2009 she was seen for suspected sialadenitis by another department and referred to our oral and maxillofacial surgery clinic. Her signs and symptoms were consistent with metastatic disease to the mandible confirmed by histologic and immunohistochemical examination which revealed an invasive poorly differentiated non-small cell carcinoma. Palliative care was offered. Our patient died 2 years after initial diagnosis of lung cancer and 3 months after initial finding of metastatic disease. The rapid growth and spread of this cancer was surprising and knowledge of this cancer should be included in a differential diagnosis of expanding mandibular jaw lesions.

    To report a single case of improvement on choroidal metastasis of breast cancer after laser photocoagulation. A 52-year-old female patient who complained of visual disturbance of the right eye with multiple states of metastasis of breast carcinoma. On initial examination, the right best-corrected visual acuity was 0.63. Right fundoscopy revealed an elevated mass-like lesion temporal to the macule with serous retinal detachment. The mass had a 3.5-disc diameter. A right fluorescein angiogram revealed hypofluorescence during the prearterial and arteriovenous phase and hyperfluorescence during the venous phase. The venous phase showed almost total masking of background choroidal fluorescence at the elevated lesion because of leakage and neovascularization. The patient was treated 4 times by diode laser photocoagulation in addition to chemotherapy. Fifty days after the diode laser treatments, the funduscopy examination and fluorescein angiogram revealed that the serous retinal detachment had been absorbed, the choroid had become flat, the lesion had been reduced in size and hyperfluorescence. The right best-corrected visual acuity was improved to 0.8. Laser photocoagulation appears not to cause any problems for the patient and may be an efficient treatment for patients with choroidal breast carcinoma. PMID:18784448

    A case of thyroid metastasis of a renal clear cell carcinoma is presented. The fine-needle aspiration cytology pointed out the primary tumor origin. The patient underwent robot-assisted radical nephrectomy and contextual thyroidectomy. During the operative procedure, a neoplastic thrombus extending from the thyroid metastasis and protruding into the internal jugular vein was found. As a result, thrombectomy and ligation of the internal jugular vein were required. In cases of single synchronous thyroid metastases form RCC, radical surgery should be advisable. Robotic approach allows to associate major surgery procedures, as nephrectomy, with radical metastasectomy.

    Purpose: This study aims to evaluate brain infiltration of metastatic tumor cells past the main tumor resection margin to assess the biological basis for the use of stereotactic radiosurgery treatment of the tumor resection cavity and visualized resection edge or clinical target volume. Methods and Materials: Resection margin tissue was obtained after gross total resection of a small group of metastatic lesions from a variety of primary sources. The tissue at the border of the tumor and brain tissue was carefully oriented and processed to evaluate the presence of tumor cells within brain tissue and their distance from the resection margin. Results: Microscopic assessment of the radially oriented tissue samples showed no tumor cells infiltrating the surrounding brain tissue. Among the positive findings were reactive astrocytosis observed on the brain tissue immediately adjacent to the tumor resection bed margin. Conclusions: The lack of evidence of metastatic tumor cell infiltration into surrounding brain suggests the need to target only a narrow depth of the resection cavity margin to minimize normal tissue injury and prevent treatment size-dependent stereotactic radiosurgery complications.

    Carcinoma of the bladder metastatic to the breast is only sporadically reported in the literature. To the best of our knowledge, the present report is the first described case of signet ring cell carcinoma of the urinary bladder metastasizing to the breast. The patient was a 43-year-old woman who underwent transurethral partial cystectomy for signet ring cell carcinoma of the urinary bladder and adjuvant chemotherapy with cisplatin and gemcitabine. At 7 months postcystectomy, the patient presented with a solitary nodule in the right breast. Following transdermic core needle puncture biopsy of the lesion and histological examination, the tumor was found to be composed of signet ring cells, which were similar to the cells in the original cystectomy specimen. The patient underwent mastectomy without further chemotherapy and has remained free from metastasis to other organs during 1 year follow-up. PMID:27330778

    We report a case of axillary lymph node metastasis as a consequence of medullary thyroid carcinoma (MTC) in a 42-year-old man. On January 2009, the patient was referred to us for the management of right cervical lymph node enlargement. Total thyroidectomy was performed with right-sided functional neck dissection. Postoperative histopathology revealed MTC in the right lobe of the thyroid, with extrathyroidal extension and right-sided neck metastases. Multiple left cervical, mediastinal, and right axillary lymphadenopathies were detected at the third year follow-up exam. Left-sided functional neck dissection, axillary lymph node dissection, and mediastinal lymph node dissection were performed, and the pathologic outcomes revealed as the metastatic dissemination of MTC. After a disease-free term for 1 year, multiple metastatic lesions were detected in the patient. PMID:25785315

    Ovarian leiomyosarcomas are extremely rare ovarian malignancies, usually associated with poor prognosis in terms of survival. Most often, ovarian leiomyosarcomas are diagnosed in postmenopausal women at an advanced stage of disease, the main symptoms consisting of abdominal pain. We present the case of a 52-year-old patient who was initially submitted to surgery for a large ruptured ovarian tumor in April 2009; at that time, total hysterectomy with bilateral adnexectomy, omentectomy, pelvic and para-aortic lymph node dissection were performed. The histopathological studies revealed the presence of an ovarian leiomyosarcoma. Five years later, the patient was diagnosed with a unique, ruptured liver metastasis and an atypical right hepatectomy was performed. The histopathological studies confirmed the metastatic origin of the lesion. At 2-year-follow-up the patient is still free from recurrent disease. PMID:27069167

    Prostate cancer is one of the most common cancers among men worldwide and in the USA. Most prostate cancer progression either locally invades to seminal vesicles or metastasizes distally to bone. Skin is not a common site of metastasis for the majority of malignancies including prostate cancer. This paper reports two extremely rare cases of prostate carcinoma metastatic to the skin: a 74-year-old man previously treated with radiation for prostate cancer with cutaneous metastases to the shoulder and a 68-year-old man with prostate adenocarcinoma and cutaneous metastases to the groin. Both patients were diagnosed with skin punch biopsy and later confirmed with immunohistochemical staining for PSA and prostate specific acid phosphatase, specific for prostatic carcinoma. Although unusual, development of multiple skin lesions in patients with prostate adenocarcinoma should raise the flags of cutaneous metastases. PMID:27568675

    Purpose: To determine how the omission of whole brain radiotherapy (WBRT) affects the neurocognitive function of patients with one to four brain metastases who have been treated with stereotactic radiosurgery (SRS). Methods and Materials: In a prospective randomized trial between WBRT+SRS and SRS alone for patients with one to four brain metastases, we assessed the neurocognitive function using the Mini-Mental State Examination (MMSE). Of the 132 enrolled patients, MMSE scores were available for 110. Results: In the baseline MMSE analyses, statistically significant differences were observed for total tumor volume, extent of tumor edema, age, and Karnofsky performance status. Of the 92 patients who underwent the follow-up MMSE, 39 had a baseline MMSE score of {<=}27 (17 in the WBRT+SRS group and 22 in the SRS-alone group). Improvements of {>=}3 points in the MMSEs of 9 WBRT+SRS patients and 11 SRS-alone patients (p = 0.85) were observed. Of the 82 patients with a baseline MMSE score of {>=}27 or whose baseline MMSE score was {<=}26 but had improved to {>=}27 after the initial brain treatment, the 12-, 24-, and 36-month actuarial free rate of the 3-point drop in the MMSE was 76.1%, 68.5%, and 14.7% in the WBRT+SRS group and 59.3%, 51.9%, and 51.9% in the SRS-alone group, respectively. The average duration until deterioration was 16.5 months in the WBRT+SRS group and 7.6 months in the SRS-alone group (p = 0.05). Conclusion: The results of the present study have revealed that, for most brain metastatic patients, control of the brain tumor is the most important factor for stabilizing neurocognitive function. However, the long-term adverse effects of WBRT on neurocognitive function might not be negligible.

    Introduction Adrenal cortical carcinoma (ACC) is a very rare type of tumor that generally has a poor prognosis. Little has been reported on repeated liver resections with recurrent metastasis still confined to the liver. In this report, we describe a case of functioning ACC in a 65-year-old woman with 2 liver metastases of the ACC (at 1.5 and 4 years) after the right adrenalectomy. Presentation of case A 65-year-old woman was referred to our hospital based on a suspicion of hyperaldosteronism. Abdominal computed tomography revealed a lesion at the right adrenal gland; therefore, we performed right adrenalectomy and subsequently diagnosed the lesion as ACC. However, follow-up computed tomography at 1.5 and 4 years after the right adrenalectomy revealed liver metastasis of ACC; liver resection was performed for both metastases. Discussion Complete surgical resection is the established approach for the treatment of ACC. The prognosis of ACC is usually dismal, and recurrence rates of up to 85% have been reported. However, the appropriate treatment for recurrent ACC is not well established, and the effectiveness of other modalities, such as chemotherapy and radiotherapy, is not proven. Therefore, surgical resection may currently be the most appropriate treatment modality, as the patient achieved a disease-free interval of 2.5 years after the first liver resection. Conclusion In selected patients with recurrent or metastatic ACC, resection is likely to be associated with prolonged survival. However, a full cure is generally not achievable, and a multidisciplinary approach is likely needed to achieve long-term disease-free status and survival. PMID:25765741

    Gangliosides (GGs), sialic acid-containing glycosphingolipids, are known to be involved in the invasive/metastatic behavior of brain tumor cells. Development of modern methods for determination of the variations in GG expression and structure during neoplastic cell transformation is a priority in the field of biomedical analysis. In this context, we report here on the first optimization and application of chip-based nanoelectrospray (NanoMate robot) mass spectrometry (MS) for the investigation of gangliosides in a secondary brain tumor. In our work a native GG mixture extracted and purified from brain metastasis of lung adenocarcinoma was screened by NanoMate robot coupled to a quadrupole time-of-flight MS. A native GG mixture from an age-matched healthy brain tissue, sampled and analyzed under identical conditions, served as a control. Comparative MS analysis demonstrated an evident dissimilarity in GG expression in the two tissue types. Brain metastasis is characterized by many species having a reduced N-acetylneuraminic acid (Neu5Ac) content, however, modified by fucosylation or O-acetylation such as Fuc-GM4, Fuc-GM3, di- O-Ac-GM1, O-Ac-GM3. In contrast, healthy brain tissue is dominated by longer structures exhibiting from mono- to hexasialylated sugar chains. Also, significant differences in ceramide composition were discovered. By tandem MS using collision-induced dissociation at low energies, brain metastasis-associated GD3 (d18:1/18:0) species as well as an uncommon Fuc-GM1 (d18:1/18:0) detected in the normal brain tissue could be structurally characterized. The novel protocol was able to provide a reliable compositional and structural characterization with high analysis pace and at a sensitivity situated in the fmol range.

    Purpose: To examine the relationship between neurocognitive function (NCF) and quality of life (QOL) in patients with brain metastases after whole-brain radiotherapy. Patients and Methods: A total of 208 patients from the whole-brain radiotherapy arm of a Phase III trial (PCI-P120-9801), who underwent regular NCF and QOL (ADL [activities of daily living] and FACT-Br [Functional Assessment of Cancer Therapy-Brain-specific]) testing, were analyzed. Spearman's rank correlation was calculated between NCF and QOL, using each patient's own data, at each time point. To test the hypothesis that NCF declines before QOL changes, the predictive effect of NCF from previous visits on QOL was studied with a linear mixed-effects model. Neurocognitive function or QOL deterioration was defined relative to each patient's own baseline. Lead or lag time, defined as NCF deterioration before or after the date of QOL decline, respectively, was computed. Results: At baseline, all NCF tests showed statistically significant correlations with ADL, which became stronger at 4 months. A similar observation was made with FACT-Br. Neurocognitive function scores from previous visits predicted ADL (p < 0.05 for seven of eight tests) or FACT-Br. Scores on all eight NCF tests deteriorated before ADL decline (net lead time 9-153 days); and scores on six of eight NCF tests deteriorated before FACT-Br (net lead time 9-82 days). Conclusions: Neurocognitive function and QOL are correlated. Neurocognitive function scores from previous visits are predictive of QOL. Neurocognitive function deterioration precedes QOL decline. The sequential association between NCF and QOL decline suggests that delaying NCF deterioration is a worthwhile treatment goal in brain metastases patients.

    Despite multimodal treatment approaches, the prognosis of brain metastases (BM) from non-small cell lung cancer (NSCLC) remains poor. Untreated patients with BM have a median survival of about 1 month, with almost all patients dying from neurological causes. We herein present the first report describing the response of BM from NSCLC patients to an oral nutraceutical product containing silibinin, a flavonoid extracted from the seeds of the milk thistle. We present evidence of how the use of the silibinin-based nutraceutical Legasil® resulted in significant clinical and radiological improvement of BM from NSCLC patients with poor performance status that progressed after whole brain radiotherapy and chemotherapy. The suppressive effects of silibinin on progressive BM, which involved a marked reduction of the peritumoral brain edema, occurred without affecting the primary lung tumor outgrowth in NSCLC patients. Because BM patients have an impaired survival prognosis and are in need for an immediate tumor control, the combination of brain radiotherapy with silibinin-based nutraceuticals might not only alleviate BM edema but also prove local control and time for either classical chemotherapeutics with immunostimulatory effects or new immunotherapeutic agents such as checkpoint blockers to reveal their full therapeutic potential in NSCLC BM patients. New studies aimed to illuminate the mechanistic aspects underlying the regulatory effects of silibinin on the cellular and molecular pathobiology of BM might expedite the entry of new formulations of silibinin into clinical testing for progressive BM from lung cancer patients.

    Metastasis (the spread of cancer from a primary tumor to secondary organs) is responsible for most cancer deaths. The ability to follow the fate of a population of tumor cells over time in an experimental animal would provide a powerful new way to monitor the metastatic process. Here we describe a magnetic resonance imaging (MRI) technique that permits the tracking of breast cancer cells in a mouse model of brain metastasis at the single-cell level. Cancer cells that were injected into the left ventricle of the mouse heart and then delivered to the brain were detectable on MR images. This allowed the visualization of the initial delivery and distribution of cells, as well as the growth of tumors from a subset of these cells within the whole intact brain volume. The ability to follow the metastatic process from the single-cell stage through metastatic growth, and to quantify and monitor the presence of solitary undivided cells will facilitate progress in understanding the mechanisms of brain metastasis and tumor dormancy, and the development of therapeutics to treat this disease.

    Brain fag was originally described as a culture-bound syndrome among West African students. The term "brain fag" literally means "brain fatigue." Available literature indicates that brain fag symptoms usually present in formal academic settings when African students are required to transit to a reliance on written literature (as opposed to more traditional oral forms of information transmission) and to adapt to westernized, individualistic systems of education that, at times, oppose the values of relatively collectivistic African societies. Based on detailed observation of two typical and two nontypical cases of brain fag, the authors suggest that the syndrome may not be solely related to tensions in the academic sphere, but may function more generally as an expression of psychological distress that results from societal pressures that exceed the coping capacity of the individual. The brain fag symptoms, including lack of concentration, sensations of internal heat in the head and body, heaviness, and multiple somatic complaints, may constitute a defensive process which helps prevent a full-fledged decompensation.

    Bone metastasis from cutaneous squamous cell carcinoma (SCC) is rare. We report a case of cutaneous SCC which was diagnosed by the presence of bone metastasis and treated with combination chemotherapy. A 53 year male had tissue contusion and persistent ulcer in the multiple regions of body for about 30 years and treat with Chinese Herbal Drugs in several hospitals, however, did not thorough cure. He was referred to our hospital for a dermatological examination in March 2009. Excisional biopsy and positron emission tomography-computed tomography (PET-CT) scan showed an invasive cutaneous SCC concomitant bone metastasis. Surgical treatment is limited, because of multiple cancerous ulcer and metastatic spreading. Therefore, we proceed to treat with oxaliplatin, tegafur and leucovorin (LV) combination chemotherapy and other adjuvant therapy. About 5 months following chemotherapy, the general situation of the patient was improved. Further cycle of chemotherapy resulted in complete disappearance of the tumor masses (confirmed by PET-CT). So far, there was no evidence of local recurrence or distant metastasis. This report indicates that the combination chemotherapy of oxaliplatin, tegafur and LV seems to have a considerable therapeutic effect for cutaneous SCC concomitant malignant bone metastasis.

    Gangliogliomas are uncommon tumors of the central nervous system and rarely occur in the lateral ventricle or present with drop metastasis. We report a 49-year-old male who presented with a six-week history of left leg pain and numbness. Clinical examination revealed no focal neurological deficits. Magnetic resonance imaging (MRI) demonstrated enhancing nodular lesions in the sacral spine abutting the S2 nerve root. Further imaging of the neuroaxis demonstrated a cystic lesion in the left frontal horn of the lateral ventricle. Gross total surgical resection of the ventricular lesion was performed through a transcortical approach, followed by resection of the sacral spinal drop metastasis in a staged manner. A histopathological analysis revealed the diagnosis of low-grade ganglioglioma. To our knowledge, this is the first reported case of a low-grade intraventricular ganglioglioma presenting with symptoms associated with drop metastasis in an adult patient.

    Melanotic schwannoma (MS) is an unusual variant of nerve sheath neoplasm. Only 10% of these tumors will undergo malignant degeneration, with exceedingly rare reported metastasis. We present a 32-year-old woman with a 6-month history of cervical pain and left arm progressive weakness. Neurological examination showed a left upper limb radicular pain, with pyramidal syndrome at C5 level. The magnetic resonance imaging (MRI) study highlighted an intradural extramedullary heterogeneous mass along the spinal cord at the C4-C5 level, slightly hyperintense with T1 and hypointense with T2-weighted sequences, invading the left neural foramen. The patient underwent C3-C5 laminectomy with total resection of a black tumor. In the postoperative period, a patent deficit of shoulder abduction ensued related to the nervous section. Microscopically, compactly fascicles of spindle-shaped cells with pleomorphic and hypercromatic nuclei, dark brown intracellular pigments, as well as some mitotic figures were seen. Immunohistochemical stains for S-100, Human Melanoma Black-45 (HMB-45), and vimentin were positive, with Ki-67 Labelling Index (LI) of 15% compatible with MS. Six months after radiotherapy she presents local recurrence and lung metastatic dissemination of the MS. She underwent left pulmonary segmentectomy, followed by chemotherapy and radiosurgery. The patient developed a febrile neutropenia and worsening of general status, and died after 3 months due to respiratory complications. MS are rare tumors with potential for local recurrence and distal metastasis. Complete surgical resection remains as the treatment of choice, once the uncommon cases with malignant progression shows low response to chemo and radiotherapy. PMID:24077273

    Background: Nocardial brain abscesses are a rare central nervous system infection with high morbidity and mortality. Infection is acquired through inhalation or direct innoculation and then spreads hematogenously. They are usually associated with immunocompromised patients but may appear in otherwise healthy individuals. Treatment is based on surgical aspiration and antibiotics for several months. Case Description: We present four cases of nocardial brain abscesses treated at our institution and review the literature regarding these lesions. Ages ranged from 22 to 71 years. One patient was a healthy individual without any predisposing condition. Patients were treated with surgical evacuation and long term parenteral antibiotics. Two patients made a full recovery; one patient died and one recovered with significant morbidity. In one case malignancy was suspected, probably delaying diagnosis. Conclusions: Nocardial brain abscesses are a rare condition that needs to be considered in the differential diagnosis of brain lesions. They are not necessarily associated with predisposing factors such as immunosupresion. Treatment must be started as soon as possible with surgical evacuation and long term parenteral antibiotics in order to avoid significant morbidity. PMID:23050202

    Background: Olfactory neuroblastoma (ONB) is a rare, aggressive tumor of the nasal cavity. It may invade the paranasal cavities and anterior skull base locally but may also metastasize to the cervical lymph nodes, lungs, or distant central nervous system. Case Description: Here, we report a case of ONB in which emergency surgery was performed for intradural spinal metastasis (ISM). The patient was a 52-year-old male who underwent surgery for ONB. The tumor extended from the nasal cavity to the intracranial space and was resected completely. After radiotherapy (60 Gy), the patient was discharged without any neurological deficit except anosmia. Seven months after the surgery, he consulted our department because of progressive tetraparesis. Cervical magnetic resonance imaging demonstrated an intradural spinal mass involving C5–T2 and necessitating emergency surgery. The tumor was resected subtotally followed by 58 Gy whole-spine irradiation. The patient's neurological symptoms improved, however, paralysis of the right upper and both the lower limbs remained. During the 4 months between the spinal surgery and his death, there was no further motor deterioration in any of his four extremities. Conclusion: This case demonstrates the need to be aware of potential ISM in the follow-up of patients with ONB. The early detection of ISM by spinal MRI is crucial to ensuring good palliative care.

    2016-01-01

    Introduction After stereotactic radiosurgery (srs) for brain metastases, patients are routinely monitored with magnetic resonance imaging (mri). The high rate of new brain metastases after srs treatment alone might not be as concerning with modern mri and target localization treatment. Intensive surveillance might induce anxiety, lowering the patient’s quality of life (qol). The present work is the feasibility component of a prospective study evaluating the role of surveillance mri on qol in patients with limited (1–3) brain metastases. Methods Patients with limited brain metastases treated with srs alone, an Eastern Cooperative Oncology Group performance status of 2 or less, and documented stability in treated lesions, with no new lesions seen on mri at weeks 6–10 after srs, were eligible. All were asked about their interest in participating in the control (mri and clinical surveillance) or the experimental arm (symptom-directed mri and clinical surveillance). If 33% or more agreed to participate in the experimental arm, it would be considered feasible to conduct the prospective study. Results From November 2014 to July 2015, 45% of patients (10 of 22) agreed to participate in the experimental arm. Subgroup analyses found that the decision to participate has no statistically significant association with time of presentation (p = 0.696), display of symptoms (p = 0.840), age (p = 0.135), or number of lesions (p = 0.171). Conclusions Results show that it is feasible to conduct the prospective cohort study. Because of the small sample size, we are limited in the conclusions able to be drawn in the subgroup analyses. However, the future study would allow for a better understanding of the attitudes of patients toward mri and its effect on qol. PMID:27803601

    Metastatic tumors involving salivary glands arising from the non-head and neck area are very rare. Renal cell carcinoma (RCC) is known for its high propensity for metastasis to unusual localizations. RCC metastasis to the maxillofacial area is an uncommon event (16%), but metastasis to salivary glands is extremely rare. We report a series of 9 such cases retrieved from two institutions. The group included 6 females and 3 males. The age at diagnosis ranged from 60 to 97 years (mean 72.6 years). The tumors involved the parotid gland in 7 cases, and the submandibular and small salivary gland of the oral cavity in 1 case each. The size of tumors ranged from 0.4 to 5 cm. Total parotidectomy with selective neck dissection was performed in 4 cases, while superficial parotidectomy was performed in 1 case and simple resection in 3 cases. Histologically, all the tumors were clear cell renal cell carcinomas, and therefore the differential diagnosis mainly included clear cell variants of salivary gland carcinomas. The parotid gland was the initial manifestation of renal malignancy in 4 of the cases, while in the remaining 5 cases a history of RCC had been known. The salivary gland involvement developed from 11 months to 13 years after the time of diagnosis of the primary tumor. In 2 cases it was the first site of dissemination. Pathologists need to maintain a high index of suspicion for the possibility of metastasis when confronted with oncocytic or clear cell neoplasms developing in salivary glands. RCC, although rare, should be included in this differential diagnosis. PMID:27179273

    Background Brain metastases (BM) represent one of the most frequent complications related to cancer, and their treatment continues to evolve. We have evaluated the activity, toxicity and the impact on Quality of Life (QoL) of a concomitant treatment with whole brain radiotherapy (WBRT) and Temozolomide (TMZ) in patients with brain metastases from solid tumors in a prospective Simon two stage study. Methods Fifty-nine patients were enrolled and received 30 Gy WBRT with concomitant TMZ (75 mg/m2/day) for ten days, and subsequently TMZ (150 mg/m2/day) for up to six cycles. The primary end points were clinical symptoms and radiologic response. Results Five patients had a complete response, 21 patients had a partial response, while 18 patients had stable disease. The overall response rate (45%) exceeded the target activity per study design. The median time to progression was 9 months. Median overall survival was 13 months. The most frequent toxicities included grade 3 neutropenia (15%) and anemia (13%), and only one patient developed a grade 4 thrombocytopenia. Age, Karnofsky performance status, presence of extracranial metastases and the recursive partitioning analysis (RPA) were found to be predictive factors for response in patients. Overall survival (OS) and progression-free survival (PFS) were dependent on age and on the RPA class. Conclusion We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p < 0.0001) demonstrated by FACT-G analysis. All patients answered the questionnaires and described themselves as 'independent' and able to act on their own initiatives. Our study found a high level of satisfaction for QoL, this provides useful information to share with patients in discussions regarding chemotherapy treatment of these lesions. PMID:17254350

    Adrenomedullin (AM) is a vasodilating peptide involved in the regulation of circulatory homeostasis and in the pathophysiology of certain cardiovascular diseases. AM plays critical roles in blood vessels, including regulation of vascular stability and permeability. To elucidate the autocrine/paracrine function of AM in endothelial cells (EC) in vivo, a conditional knockout of AM in EC (AMEC-KO) was used. The amount of vascularization of the matrigel implants was lower in AMEC-KO mice indicating a defective angiogenesis. Moreover, ablation of AM in EC revealed increased vascular permeability in comparison with wild type (WT) littermates. In addition, AMEC-KO lungs exhibited significantly less tumor growth than littermate WT mice using a syngeneic model of metastasis. Furthermore, following middle cerebral artery permanent occlusion, there was a significant infarct size decrease in animals lacking endothelial AM when compared to their WT counterparts. AM is an important regulator of EC function, angiogenesis, tumorigenesis, and brain response to ischemia. Studies of AM should bring novel approaches to the treatment of vascular diseases.

    Tuberculosis (TB) presenting as isolated liver mass without clinical evidence of TB is difficult to diagnose preoperatively and is usually mimicked by primary or metastatic carcinoma of the liver. Hepatic TB associated with carcinoma colon is a rare association which has very rarely been reported in the literature. This case illustrates the diagnostic difficulties of hepatic TB and the need to consider it in the differential diagnosis of hepatic nodular lesions in carcinoma colon patients. Here, we report a case of 48-year-old female who presented in the casualty with features of acute intestinal obstruction. Preoperatively a mass was seen at the hepatic flexure along with three lesions in the liver presumed to be metastatic in origin. However, histopathology of the mass revealed adenocarcinoma colon and the liver lesion proved to be hepatic TB. We wish to highlight that on encountering a hepatic lesion in a carcinoma colon patient the possibility of hepatic TB should also be kept in mind apart from the obvious possibility of metastasis especially in an endemic country like India.

    Dedifferentiated endometrial cancer (DEC) is microscopically characterized by the presence of high-grade areas emerging from low-grade tumour. DEC is an aggressive tumour even when the dedifferentiated component represents only 20% of the entire neoplasm. A proper histological diagnosis is essential to define the most appropriate therapeutic approach for these tumors, since they are characterized by a particularly aggressive trend and by an extremely poor prognosis. We report a single case of DEC associated with dedifferentiated and adrenal metastasis, for which the patient underwent both abdominal-pelvic and cerebellar surgery. Dedifferentiated carcinoma of the endometrium is a poorly recognized neoplasm since they have not been clearly defined the histological features discriminating this neoplasm from high-grade endometrioid adenocarcinoma. Revising existing literature we found 79 described cases of central nervous system secondary involvement and 13 cases where the onset of the disease was characterized by neurological signs and symptoms. We could only find two reported cases of adrenal metastases originating from endometrial neoplasia but in no case of dedifferentiated endometrial carcinoma previously described has been reported the concomitant adrenal-cerebellar involvement.

    Mesenteric leiomyosarcoma is a rare disease with poor prognosis. Previously, mesenteric leiomyosarcoma was not differentiated from gastrointestinal stromal tumor (GIST), which is the most common mesenchymal tumor of the gastrointestinal tract, and several cases of GIST may have been misclassified as mesenteric leiomyosarcoma. Thus, the actual clinicopathological characteristics of mesenteric leiomyosarcomas remain unclear. We herein describe a case of leiomyosarcoma arising in the descending mesocolon in a patient who developed metachronous liver metastasis. A 76-year-old woman reported a mass in her left upper abdomen. Computed tomography imaging revealed a low-density tumor adjacent to the descending colon. The patient underwent surgery and the tumor was resected along with part of the descending colon. Immunohistochemical differential diagnosis revealed that the tumor was positive for smooth muscle actin and desmin, and negative for CD117 (c-KIT) and S-100, which are characteristic of gastrointestinal leiomyosarcoma. A single liver metastasis developed 24 months after the operation. The patient underwent curative resection of the metastatic lesion. Sixteen months following surgery for the liver metastasis and 40 months after the initial removal of the primary lesion, the patient remains disease-free. The prognosis of leiomyosarcoma remains poor and standardized chemotherapy for this rare disease has not yet been established. Early diagnosis and surgical removal of the tumor is the only potentially curative option for liver metastasis of mesenteric leiomyosarcoma. PMID:27330765

    Purpose Stereotactic radiosurgery (SRS) has been introduced for small-sized single and oligo-metastases in the brain. The aim of this study is to assess treatment outcome, efficacy, and prognostic variables associated with survival and intracranial recurrence. Materials and Methods This study retrospectively reviewed 123 targets in 64 patients with non-small cell lung cancer (NSCLC) treated with SRS between January 2006 and December 2012. Treatment responses were evaluated using magnetic resonance imaging. Overall survival (OS) and intracranial progression-free survival (IPFS) were determined. Results The median follow-up was 13.9 months. The median OS and IPFS were 14.1 and 8.9 months, respectively. Fifty-seven patients died during the follow-up period. The 5-year local control rate was achieved in 85% of 108 evaluated targets. The 1- and 2-year OS rates were 55% and 28%, respectively. On univariate analysis, primary disease control (p < 0.001), the Eastern Cooperative Oncology Group (ECOG) performance status (0-1 vs. 2; p = 0.002), recursive partitioning analysis class (1 vs. 2; p = 0.001), and age (<65 vs. ≥65 years; p = 0.036) were significant predictive factors for OS. Primary disease control (p = 0.041) and ECOG status (p = 0.017) were the significant prognostic factors for IPFS. Four patients experienced radiation necrosis. Conclusion SRS is a safe and effective local treatment for brain metastases in patients with NSCLC. Uncontrolled primary lung disease and ECOG status were significant predictors of OS and intracranial failure. SRS might be a tailored treatment option along with careful follow-up of the intracranial and primary lung disease status. PMID:26484304

    Solitary fibrous tumor (SFT) is a rare spindle cell tumor of mesenchymal origin that usually arises from pleura or pericardium but can also arise from many extraserosal sites. Although more than 50 cases of primary SFT of the orbit have been reported, there are no reports to date of a malignant nonophthalmic SFT metastasizing in the orbital soft tissues (although sphenoid wing bony involvement has been reported). The authors report here the first case of a patient with intraorbital metastasis of a CD34-positive malignant SFT. The patient was a 57-year-old man with a history of malignant pleural SFT and a prior kidney metastasis. He presented with the rapid appearance of proptosis and massive conjunctival chemosis preventing eyelid closure, and he was found to have a well-circumscribed metastasis to his lateral rectus muscle. Surgical excision cured his ocular symptoms, although he died 3 months later from brain and widespread metastases.

    Despite great efforts to improve survival rates, the prognosis of lung cancer patients is still very poor, mainly due to high invasiveness. We developed brain metastatic PC14PE6/LvBr4 cells through intracardiac injection of lung adenocarcinoma PC14PE6 cells. Western blot and RT-qPCR analyses revealed that PC14PE6/LvBr4 cells had mesenchymal characteristics and higher invasiveness than PC14PE6 cells. We found that cyclin D1 was upregulated, miR-95-3p was inversely downregulated, and pri-miR-95 and its host gene, ABLIM2, were consistently decreased in PC14PE6/LvBr4 cells. MiR-95-3p suppressed cyclin D1 expression through direct binding to the 3' UTR of cyclin D1 mRNA and suppressed invasiveness, proliferation, and clonogenicity of PC14PE6/LvBr4 cells. Ectopic cyclin D1 reversed miR-95-3p-mediated inhibition of invasiveness and clonogenicity, demonstrating cyclin D1 downregulation is involved in function of miR-95-3p. Using bioluminescence imaging, we found that miR-95-3p suppressed orthotopic tumorigenicity and brain metastasis in vivo and increased overall survival and brain metastasis-free survival. Consistent with in vitro metastatic cells, the levels of miR-95-3p, pri-miR-95, and ABLIM2 mRNA were decreased in brain metastatic tissues compared with lung cancer tissues and higher cyclin D1 expression was involved in poor prognosis. Taken together, our results demonstrate that miR-95-3p is a potential therapeutic target for brain metastasis of lung adenocarcinoma cells.

    We present a case of a 66-year-old man with esophageal carcinoma. 18Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for evaluating distant metastasis and staging revealed 18F-FDG uptake in the third lumbar vertebra and other vertebrae. Magnetic resonance imaging could not differentiate bone metastases from benign bone lesions. We considered the possibility of bone marrow reconversion. 111Indium chloride (111In-Cl3) scintigraphy with single-photon emission computed tomography/computed tomography (SPECT/CT) revealed erythroid bone marrow components in the bone lesions. The diagnosis of bone marrow reconversion was pathologically confirmed by a bone biopsy of the third lumbar vertebra. The patient underwent esophagectomy and has remained disease-free in the 2 years since. To the best of our knowledge, this is the first report to describe the usefulness of 111In-Cl3 with SPECT/CT for the diagnosis of bone marrow reconversion. PMID:27549674

    Spontaneous excavation of primary lung cancer is common; however cavitation of metastatic lung lesions is rare and usually confused with benign lesions. In Moroccan context tuberculosis is the first suspected diagnosis of lung excavations. We report a rare case of cavitary lung metastasis of a uterine cervix cancer, treated initially as tuberculosis. A 40-year old non-smoking woman with a known history of squamous cell carcinoma of the uterine cervix since August 2005; presented on September 2008 with right chest pain without fever, hemoptysis or weight loss. CT scan showed a thin walled cavity. Empirical Antibiotic therapy was conducted 15 days with poor outcome. Then antibacillary treatment was started with no proof of mycobacterial infection. A month later, the patient presented with gynecological bleeding and a pneumothorax. Bronchoscopy with transbronchial biopsy of the cavitary mass was performed. Pathology demonstrated a metastatic squamous cell carcinoma. Pelvic examination and MRI showed a subsequent local cervix recurrence. Patient underwent 3 courses of systemic chemotherapy. She died on June 2009 due to progressive disease. Even cavitary lung metastases are rare and benign differential diagnosis are more common, clinician should be careful in neoplastic context and investigation should be done to eliminate a recurrence.

    In recent years, human papillomavirus (HPV)-positive oropharyngeal carcinomas have been increasing. The first manifestation of these tumors is frequently as cystic metastasis to cervical lymph nodes that may precede recognition of the primary tumor, so, they often result in misdiagnosis as branchial cleft cysts. We report a case of cystic cervical lymph node metastasis of HPV-positive tonsil cancer. The patient was a 70-years-old man who noticed a mass on his left neck. The tumor was large and soft, and it was diagnosed as benign in fine-needle aspiration cytology. We diagnosed the tumor as a branchial cleft cyst and undertook surgery. The histopathological diagnosis was squamous cell carcinoma arising from a branchiogenic cyst. However, because it did not satisfy the diagnostic criteria, we diagnosed the tumor as an unknown primary tumor. One year later, left tonsil cancer was suspected based on PET-CT imaging and a left tonsillectomy was undertaken, whereafter tonsil cancer was found. In p16 immunostaining, it was positive in both cystic mass and tonsil. The cervical mass was cystic lymph node metastasis of HPV-positive tonsil cancer. It is important to investigate the oropharynx, when we found cystic cervical mass, because HPV-positive oropharyngeal carcinoma frequently results in cystic neck metastasis.

    Gastrointestinal (GI) metastasis of hepatocellular carcinoma is very rare. This is the first report of post-transplantation gastric metastasis. A 43-year-old man with a history of hepatitis B-related hepatocellular carcinoma (HCC) in the right anterior segment of the liver received an orthotopic liver transplant. Three months after the transplantation, pulmonary metastasis was found by chest computed tomography, and he received 1 course of gamma knife treatment. He complained of melena with anemia 17 months post liver transplantation. Abdominal CT scan showed new occupying lesions in the liver and a mass in the stomach and around the spleen with embolus in the splenic vein. Endoscopy revealed a large irregular cauliflower-like mass in fundus with ulceration and bleeding on the surface. He received symptomatic treatment, but died of cancer-related bleeding 4 months later. GI bleeding may due to gastric metastasis after liver transplantation. PMID:26518968

    Prostate cancer is one of the most common carcinomas in Asia, as well as all over the world. The vast majority of prostate cancer patients present with bone metastases, which mainly involve the axial bones, with pain as the most common symptom. The present study reports the first case of prostate cancer metastasis to the hallux in a 73-year-old man who presented with pain and a swollen phalanx of the left hallux. This symptom developed gradually over a period of several months and could not be improved with the common treatments. Due to a pathological fracture, amputation of the left phalanx was performed. Notably, the immunohistochemical examinations of the surgical sample demonstrated the presence of a metastatic lesion from prostate cancer. The present study describes an unusual presentation involving phalangeal metastasis in a prostate cancer patient, and a systematic review of reported cases of rare metastatic events in prostate cancer is also discussed.

    Metastatic prostate cancer recurrence after definitive local therapy can occur in any tissue. Usually, the first affected site is the bone. Lung metastases without bone or lymph node involvement are extremely rare in patients with prostate cancer, and only a handful of cases are reported in the literature. In several other malignancies, such as breast cancer, sarcomas, colorectal cancer, and renal cell carcinoma, long-term disease-free survival has been reported after resection of solitary pulmonary metastases. We present three unusual cases of isolated pulmonary recurrence of prostate cancer after initial definitive local therapy. One of the patients underwent resection of the lung metastasis, resulting in a long-term disease-free survival. Both surgical excision of solitary and oligometastatic lung secondary lesions and systemic therapy can play an important role in long-term disease control. Surgery should be considered for selected and well-informed patients with pulmonary metastasis after primary localised treatment for prostate cancer. PMID:27350790

    Glioblastoma (GBM) is the most common malignant tumor in adults. Extracranial metastasis of GBM is very rare. The incidence of brainstem glioblastoma is not known due to low biopsy and resection rates. In this case report, we experienced an 11-year-old male who was diagnosed as a case of pontine GBM after biopsy of lesion and underwent radiotherapy with adjuvant chemotherapy. He presented with a subcutaneous swelling in the nape of neck 1 year after the first procedure. Swelling was excised. Pathological examination and immunohistochemical staining confirmed it as GBM. This case shows us that GBM can at times present as a swelling in soft tissue. PMID:26962352

    Stereotactic hypofractionated radiotherapy after resection of brain metastasis is an alternative to whole brain radiotherapy. A high dose per fraction is associated with a risk of radiation necrosis. We present four cases of confirmed histological radiation necrosis. Differentiating recurrent tumour from radiation necrosis in this scenario is challenging. An enhancing area in magnetic resonance imaging (MRI) with a "cut bell pepper" appearance may suggest radiation necrosis. Advanced imaging modalities such as perfusion MR imaging and positron emission tomography can be useful. Dosimetric predictors of the occurrence of radiation necrosis after stereotactic hypofractionated radiotherapy are poorly understood and require prospective studies on larger cohorts.

    A 47-year-old woman had undergone breast-conserving treatment for right breast cancer (T3, N1, M0, Stage IIIA, human epidermal growth factor receptor[ HER]-2 enriched subtype) after primary systemic chemotherapy with trastuzumab. Pathological examination revealed a quasi-pathological complete response( CR) in the breast tumor and no axillary nodal involvement. The patient then received conventional breast irradiation and adjuvant trastuzumab therapy. However, adjuvant anti- HER2 therapy was discontinued in the 19th week because of a decreased left ventricular ejection fraction( approximately 50%). A left adrenal tumor was detected by abdominal computed tomography (CT) 2 years after surgery. Positron emission tomography( PET) scans showed strong accumulation in the left adrenal gland and in the lymph node near the adrenal tumor. No other obvious lesion was detected on meticulous examination. Laparoscopic adrenalectomy was performed for diagnosis and treatment. Pathological examination of the resected specimen revealed that the tumor was a metastatic adenocarcinoma with overexpression of the HER2 protein but without expression of hormonal receptors. The patient received 12 cycles of chemotherapy with paclitaxel and trastuzumab, which was followed by trastuzumab monotherapy. However, trastuzumab monotherapy could not be continued because the left ventricular ejection fraction decreased to 50% at 24 weeks after initiation of chemotherapy. The patient has been observed since the cessation of trastuzumab, without the administration of anticancer therapy, and she continues to have a good performance status without relapse. Herein, we report a case of solitary adrenal metastasis from breast cancer, an extremely rare condition, and review the relevant literature.

We report the case of a 68-year-old man with history of treated uveal melanoma of the right eye that developed metastasis to the liver and the choroid of the left eye. Ten years earlier, he was diagnosed to have uveal melanoma of the right eye and was initially treated with plaque radiotherapy. Two years later, upon progression of the disease in the right eye he had enucleation of the eye. We describe the patient's clinical history, the diagnosis of recurrent disease in the contralateral eye, therapy of the left eye, and systemic metastasis. In addition, we reviewed the published medical literature and described the recent advances in the management of uveal melanoma. PMID:25874144

    A 77-year-old man was found to have advanced gastric cancer and underwent total gastrectomy (pT4aN2H0P0M0, Stage ⅢB). Two years after gastrectomy, we found an elevated tumor marker level, and a liver metastasis appeared in segment 5 (20 mm in diameter). He was treated with S-1/CDDP combination chemotherapy. After 2 courses of chemotherapy, the tumor marker level kept rising and a CT scan detected a progressive tumor. S-1/irinotecan combination chemotherapy was administered as second-line chemotherapy. After 6 courses of chemotherapy, the size of the liver metastasis was reduced and the tumor marker level normalized. Because lymph node metastasis or peritoneal recurrence was observed, a partial resection of the liver (S5) was performed. After the operation, he was treated with S-1 chemotherapy again for 1 year and has had no recurrence. PMID:26805242

    Intracranial metastasis is unusual in osteosarcoma. A case of osteosarcoma was presented with a large intracranial "stone" which was a subdural convexity metastasis. Smaller epidural metastases over other areas were noted also in brain CT scan. Using the radiographs and bone scans, many other lesions at bones, the mediastinum, pleura, perirenal space, and adrenal gland were detected simultaneously. This condition might result from either early metastases or multifocal osteosarcomas. Because many of the above lesion sites were not frequent locations of primary osteosarcoma and had been reported as metastatic targets of osteosarcoma. So the explanation of a very malignant osteosarcoma with early metastases may be more appropriate for this case. The baseball-like tumor in the subdural space with marked compression of the brain surface was grossly totally excised. Histopathologic examination confirmed the diagnosis of osteosarcoma. Postoperatively, the man's condition improved dramatically, though only for two months. He died 5 months later. Reports of such metastatic osteosarcomas are reviewed.

    Leptomeningeal carcinomatosis (LMC) is an exceedingly rare event especially as a first manifestation of an occult primary colorectal cancer and even when there is a known history of malignancy. Sensorineural hearing loss is by itself an unusual isolated presentation of LMC with unsolved pathophysiology in this setting. In this paper, we report such a case and review the literature for similar cases, focusing on postulated mechanisms of spread. In view of the poor prognosis they carry, we highly recommend that physicians be aware of the risk of rare metastasis from colorectal adenocarcinoma in order to establish an early confirmative diagnosis.

    Purpose: To report the outcome of patients with synchronous, solitary brain metastasis from non-small-cell lung cancer (NSCLC) treated with gamma knife stereotactic radiosurgery (GKSRS). Patients and Methods: Forty-two patients diagnosed with synchronous, solitary brain metastasis from NSCLC were treated with GKSRS between 1993 and 2006. The median Karnofsky performance status (KPS) was 90. Patients had thoracic Stage I-III disease (American Joint Committee on Cancer 2002 guidelines). Definitive thoracic therapy was delivered to 26/42 (62%) patients; 9 patients underwent chemotherapy and radiation, 12 patients had surgical resection, and 5 patients underwent preoperative chemoradiation and surgical resection. Results: The median overall survival (OS) was 18 months. The 1-, 2-, and 5-year actuarial OS rates were 71.3%, 34.1%, and 21%, respectively. For patients who underwent definitive thoracic therapy, the median OS was 26.4 months compared with 13.1 months for those who had nondefinitive therapy, and the 5-year actuarial OS was 34.6% vs. 0% (p < 0.0001). Median OS was significantly longer for patients with a KPS {>=}90 vs. KPS < 90 (27.8 months vs. 13.1 months, p < 0.0001). The prognostic factors significant on multivariate analysis were definitive thoracic therapy (p = 0.020) and KPS (p = 0.001). Conclusions: This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy.

    Adrenal metastasis is an unusual site of disease involvement in the natural course of differentiated thyroid carcinoma (DTC). This paper discusses the clinical and imaging features of DTC with adrenal metastasis. An unusual case of unilateral solitary asymptomatic adrenal metastasis in the setting of DTC is described in this report with the imaging features including 131I scintigraphy and Fluorodeoxyglucose- Positron emission tomography/computed tomography. The adrenal metastasis was associated with other sites of metastatic disease involvement and was unidentified on initial pre-treatment evaluation studies. All such suspicious lesions should be further evaluated with clinicoradiological correlation by other imaging modalities. A post-radioiodine therapy scan revealed radioiodine uptake in the thyroid bed, sternum and a focus of intense radioiodine concentration in the left suprarenal region. Spot oblique images and single photon emission computed tomography of the upper abdomen was undertaken to ascertain the position and better characterization of the lesion. A subsequent whole body PET-CT (non-contrast) was done which revealed a well defined 6.5 cm × 5.0 cm left adrenal lesion with a SUVmax (standardized uptake value-maximum) of 9.5 in addition to a fluorodeoxyglucose avid osteolytic sternal lesion. The serum thyroglobulin level was significantly raised (more than 250 ng/mL) with thyroid stimulating hormone being 4.9 μΙU/mL (even following an adequate period of levothyroxine withdrawal), indicating the functioning nature of the metastases. In addition to demonstrating an atypical site of metastatic disease in DTC patients, this case emphasizes the importance of carefully interpreting and correlating a post radio-iodine therapy scan, particularly those with focal abdominal radio-iodine uptake which could aid in detecting metastatic lesions that are not characterized or identified on initial evaluation.

    The authors describe a case of glioblastoma multiforme (GBM) associated with previous gamma knife radiosurgery for a cerebral arteriovenous malformation (AVM). A 14-year-old boy had undergone radiosurgery for an AVM, which was performed using a 201-source 60Co gamma knife system at another institution. The maximum and margin radiation doses used in the procedure were 40 and 20 Gy, respectively. One year after radiosurgery, the patient noticed onset of mild left hemiparesis due to radiation necrosis. Six and one-half years after radiosurgery, at the age of 20 years, the patient experienced an attack of generalized tonic-clonic seizure. Magnetic resonance (MR) imaging revealed the existence of a brain tumor in the right parietal lobe. The patient underwent an operation and the histological diagnosis of the lesion was GBM. Ten months following the operation, that is, 99 months postradiosurgery, this patient died. To the best of the authors' knowledge, this is the first reported case of a neoplasm induced by radiosurgery for an AVM and the second case in which it occurred following radiosurgery for intracranial disease.

This neoplasm exhibits rich vascularity, a characteristic it shares with renal cell carcinoma, making these tumors especially suitable for harboring metastases. We present a case of a 64-year-old woman with history of right breast cancer treated six years previously and who presents with a left pulmonary SFT containing metastatic invasive ductal breast carcinoma as well as a synchronous contralateral primary adenocarcinoma of the lung. The literature on tumor-to-tumor metastasis is then reviewed.

    Metastatic spinal tumors are usually quite difficult to treat. In patients with metastatic spinal tumors, conventional radiotherapy fails to relieve pain in 20–30% of cases and open surgery often causes considerable trauma and complications, which delays treatment of the primary disease. Percutaneous vertebroplasty (PVP) is considered to be useful in achieving rapid pain control and preventing further vertebral collapse due to spinal metastasis. However, symptoms of intraspinal neural compression can be contraindications to PVP. To overcome this problem, we performed PVP following targeted bipolar radiofrequency decompression, and examined the effect of the combined treatment in relieving severe radicular pain related to spinal cord compression caused by malignant metastatic tumors.

    Ewing sarcomas (ES) and peripheral primitive neuroectodermal tumors (pPNET) are now thought to belong to the same tumor family. Ewing sarcoma family tumor (ESFT) members commonly originate in bones and soft tissues. However, a few published articles describe ESFT arising from cranial cavities. Pathologically, ES/pPNET are composed of small round cells. Unambiguous distinction between pPNET and other small round cell tumors, in particular central PNET, is of clinical significance. Definitive diagnoses of pPNET can be obtained through CD99 (MIC2 gene product) membrane positivities and molecular identifications of chromosomal rearrangements between EWS and ETS family genes. Multimodal approaches comprising surgical resections, radiotherapies, and chemotherapies are required for the treatment of ESFT. Decompressive medical measures are preferentially performed when epidural masses are compressing spinal cords. In cases of ES-induced brain herniations, emergent radiotherapies may serve as effective tools. We report a case of multiple disseminated intracranial ES/pPNET for which synthetic treatments were used. PMID:27330312

    We report three cases of brain abscess in children admitted to QECH in 2006. All children were HIV-uninfected. One case was associated with staphylococcal empyema, another with chronic suppurative otitis media and mastoiditis, and the third case had no identified extracranial focus of infection. These cases illustrate the difficulties of diagnosis and management of brain abscesses in the resource-poor setting where other causes of infection of the central nervous system are common. The typical clinical presentation of brain abscess of altered mental state and seizures is also characteristic of cerebral malaria and meningitis and it is likely that many cases of brain abscess in Malawian children are not diagnosed. The value of cranial CT scan, ideally with contrast, for diagnosis and management of brain abscess is highlighted by these cases.

    Brain metastasis of breast cancer is an important clinical problem, with few therapeutic options and a poor prognosis. Recent data have implicated mixed lineage kinase 3 (MLK3) in controlling the in vitro migratory capacity of breast cancer cells, as well as the metastasis of MDA-MB-231 breast cancer cells from the mammary fat pad to distant lymph nodes in a mouse xenograft model. We therefore set out to test whether MLK3 plays a role in brain metastasis of breast cancer cells. To address this question, we used a novel, brain penetrant, MLK3 inhibitor, URMC099. URMC099 efficiently inhibited the migration of breast cancer cells in an in vitro cell monolayer wounding assay, and an in vitro transwell migration assay, but had no effect on in vitro cell growth. We also tested the effect of URMC099 on tumor formation in a mouse xenograft model of breast cancer brain metastasis. This analysis showed that URMC099 had no effect on the either the frequency or size of breast cancer brain metastases. We conclude that pharmacologic inhibition of MLK3 by URMC099 can reduce the in vitro migratory capacity of breast cancer cells, but that it has no effect on either the frequency or size of breast cancer brain metastases, in a mouse xenograft model.

    Gastrointestinal stromal tumors (GISTs) are potentially malignant mesenchymal tumors that can give rise to distant metastases, mainly in the liver. The co-occurrence of synchronous primary liver tumors (e.g., hepatocellular carcinoma (HCC)) in patients with GIST is extremely rare. This report describes a 77-year-old male patient with liver metastasis of GIST originating in the small intestine and synchronous HCC. The patient had undergone resection of the small intestine for the primary GIST 3 years earlier and partial hepatectomy and radiofrequency ablation for liver metastases of GIST 1 year earlier. Despite the continuation of adjuvant therapy with imatinib, two new lesions in the liver were detected by follow-up computed tomography scanning, which showed the gradual enlargement of one tumor. A second hepatectomy was performed. Pathological examination revealed that one tumor was a liver metastasis of GIST and the other was a primary HCC. To our knowledge, this is the first report of the synchronous co-occurrence of a liver metastasis of GIST and a primary HCC. PMID:27586263

    Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach. PMID:25649759

    Breast cancer, after lung cancer, is the second major cause of brain metastases. In breast cancer, the prognosis is closely linked to the molecular subtype of the primary tumor. Targeted therapies, with or without cytotoxic treatment, have significantly modified overall survival in these patients. We report, the case of a patient suffering from breast cancer with brain metastasis in whom the biological documentation of the metastatic disease permitted to tailor the systemic treatment. Analysis of the surgical specimen revealed an immunohistochemical HER2 positive staining, which was not found in the primary tumor and therefore warranted trastuzumab administration. Another interesting insight based on this case report was to underline the phenotypic heterogeneity of the metastatic disease and its potential dynamic course as illustrated by the dissociated response to trastuzumab on body TEP-TDM in this particular patient. This case report also highlights the new place of the neurosurgeon in brain metastases management, not only as a participant in local treatment but also as a physician who is in fact involved in the delineation of the global oncological strategy in these patients as well as medical oncologists and radiation oncologists.

    Purpose: Synchrotron stereotactic radiotherapy (SSRT) is an innovative treatment combining the selective accumulation of heavy elements in tumors with stereotactic irradiations using monochromatic medium energy x-rays from a synchrotron source. Phase I/II clinical trials on brain metastasis are underway using venous infusion of iodinated contrast agents. The radiation dose enhancement depends on the amount of iodine in the tumor and its time course. In the present study, the reproducibility of iodine concentrations between the CT planning scan day (Day 0) and the treatment day (Day 10) was assessed in order to predict dose errors. Methods: For each of days 0 and 10, three patients received a biphasic intravenous injection of iodinated contrast agent (40 ml, 4 ml/s, followed by 160 ml, 0.5 ml/s) in order to ensure stable intra-tumoral amounts of iodine during the treatment. Two volumetric CT scans (before and after iodine injection) and a multi-slice dynamic CT of the brain were performed using conventional radiotherapy CT (Day 0) or quantitative synchrotron radiation CT (Day 10). A 3D rigid registration was processed between images. The absolute and relative differences of absolute iodine concentrations and their corresponding dose errors were evaluated in the GTV and PTV used for treatment planning. Results: The differences in iodine concentrations remained within the standard deviation limits. The 3D absolute differences followed a normal distribution centered at zero mg/ml with a variance (∼1 mg/ml) which is related to the image noise. Conclusion: The results suggest that dose errors depend only on the image noise. This study shows that stable amounts of iodine are achievable in brain metastasis for SSRT treatment in a 10 days interval.

    Background: Urothelial carcinoma occurs in the bladder, upper urinary tract, and lower urinary tract, including prostatic urethra. A majority of the reported cases of intracranial metastasis from urothelial carcinoma originates from the bladder and upper urinary tract. Brain metastasis from urothelial carcinoma of the prostatic urethra has not yet been reported in the literature. Case Description: A 72-year-old male presented with a metastatic brain tumor and a 3-year history of urothelial carcinoma of the prostatic urethra treated with cystourethrectomy and chemotherapy with gemcitabine-cisplatin. Pathological diagnosis for tumor removal was compatible with metastatic brain tumor from urothelial carcinoma. Conclusion: Brain metastasis from urothelial carcinoma of the prostatic urethra has not yet been reported in the literature. It is an extremely rare case, however, we should be careful of brain metastasis during follow-up for urothelial carcinoma in the lower urinary tract. PMID:27512612

    Metastases to the breast from extramammary malignancies are extremely rare. Ruling out the diagnosis of primary breast tumor is important in order to decide on clinical management and predict prognosis. We report a case of metastasis to the breast from a pulmonary adenocarcinoma, with extensive micropapillary component, diagnosed concomitantly with the primary tumor. A 52 year-old female patient presented with mammary gland tingling and dyspnea accompanied with fatigued of 4 months duration and a nodular shadows in the front of the upper lobe was found on a chest computed tomography (CT) scan. The original clinical diagnosis was right breast cancer with lung and bone metastasis, or breast and lung double primary cancers. In addition,on physical examination a poorly defined mass was noted in the upper outer quadrant of the right breast. The patient underwent thoracocentesis and breast biopsy. By imageology, cytology, histology and immunohistochemistry, we diagnosed primary lung cancer with metastases to the right breast and bone. The metastatic anatomic sites demonstrated histologically extensive micropapillary component, which is recently recognized as an important prognostic factor. The patient was administered 4 cycles of cisplatin and docetaxel, although no clinical response was seen, the patient is still alive 9 months after diagnosis. The result of immunohistochemistry is a useful supplement in differential diagnosis. PMID:26464732

    A 61-year-old man was seen in the Oral Pathology Department with a three-month history of right mandibular pain. Clinical examination revealed a 3 cm mass involving the body and the angle of the right site of the mandible and palpable masses in the neck. The dental panoramic radiography showed on the right a radiolucenT area surrounding the lower second molar, extending to the mandible angle. Additionally, chest radiograph and routine laboratory analysis results were unremarkable. An incisional biopsy of the area, revealed histologically a well differentiated squamous cell carcinoma and after few days, the patient received a right hemimandibulectomy with dissection of submandibular salivary gland and laterocervical lymph nodes on the same side. The histology of surgical material confirmed the diagnosis of a differentiated squamous cell carcinoma G1, homolateral diffusion in the mandible bone and metastasis to the dental pulp of the second lower molar tooth and to one of 18 lymph nodes dissected. In this report is described a very rare metastasis to the dental pulp and literature review, in which only fifteen other cases are reported.

    Adrenocortical carcinoma is a rare tumor with high aggresivity that can associate systemic metastases. A 71-year-old man was hospitalized for gastric cancer. The abdominal computed tomography also revealed a tumor above the right kidney. Total gastrectomy and right adrenalectomy were performed. The encapsulated tumor of the adrenal gland weighed 560 grams and presented diffuse tumor architecture under microscope, with capsular, sinusoidal, and vascular invasion. The large tumor cells had a polygonal shape, with slight basophilic, eosinophilic, or vacuolated cytoplasm, pleomorphic nuclei, and a high mitotic rate. In the stomach, the protruded tumor was covered by normal mucosa; under microscope, the tumor cells were observed only in the submucosal layer. In primary adrenal tumor and gastric metastasis the tumor cells were marked by vimentin, inhibin, synaptophysin, neuron-specific enolase, and calretinin. Based on these criteria, the diagnosis of adrenocortical carcinoma (ACC) with gastric metastasis and no lymph node metastases was established. A synchronous 10 × 10-mm-sized gastrointestinal stromal tumor (GIST) of the stomach, without mitoses, was also identified. So far, as we know, this is the 15th case of ever reported synchronous/metachronous sporadic ACCs; the ACC-related gastric metastases either synchronous ACC and GIST, has not been reported in the literature previously.

    Background Tumor cell fusion with motile bone marrow-derived cells (BMDCs) has long been posited as a mechanism for cancer metastasis. While there is much support for this from cell culture and animal studies, it has yet to be confirmed in human cancer, as tumor and marrow-derived cells from the same patient cannot be easily distinguished genetically. Methods We carried out genotyping of a metastatic melanoma to the brain that arose following allogeneic bone-marrow transplantation (BMT), using forensic short tandem repeat (STR) length-polymorphisms to distinguish donor and patient genomes. Tumor cells were isolated free of leucocytes by laser microdissection, and tumor and pre-transplant blood lymphocyte DNAs were analyzed for donor and patient alleles at 14 autosomal STR loci and the sex chromosomes. Results All alleles in the donor and patient pre-BMT lymphocytes were found in tumor cells. The alleles showed disproportionate relative abundances in similar patterns throughout the tumor, indicating the tumor was initiated by a clonal fusion event. Conclusions Our results strongly support fusion between a BMDC and a tumor cell playing a role in the origin of this metastasis. Depending on the frequency of such events, the findings could have important implications for understanding the generation of metastases, including the origins of tumor initiating cells and the cancer epigenome.

    The aims of radiotherapeutic treatment of brain metastases include maintaining neurocognitive function and improvement of survival. Based on these premises, we present a case report in which the role of repeat stereotactic radiosurgery (SRS) was investigated in a patient with a recurrent brain metastasis from non-small cell lung cancer in the same area as previously treated with radiosurgery. A 40-year-old male caucasian patient was diagnosed with brain metastasis from non-small cell lung cancer (NSCLC) and underwent SRS. The patient developed a recurrence of the disease and a second SRS on the same area was performed. After 8 months, tumor restaging demonstrated a lesion compatible with a recurrence and the patient underwent surgery. Histological diagnosis following surgery revealed only the occurrence of radionecrosis. Radiotherapy was well-tolerated and no grade 3/4 neurological toxicity occurred. To date, no consensus exists on the efficacy of retreatment with SRS. Despite the limited number of studies in this field, in the present case report, we outline the outcomes of this unconventional approach. PMID:24137433

    This retrospective study was conducted to assess the efficacy of combination of pemetrexed and cisplatin/carboplatin as first-line treatment in inoperable and asymptomatic brain metastasis (BM) from non-small cell lung cancer (NSCLC). A total of 30 patients with adenocarcinoma were included. Nine patients had solitary, and 21 patients had multiple BM. At evaluation after two cycles, the complete response (CR) rate, partial response (PR) rate, and stable disease (SD) for brain lesions was 0, 33.3, and 46.7%, respectively. The overall CR, PR, and SD were 0, 23.3, and 46.7%, respectively. The median time to tumour progression of BM (TTP-BM) was 6.0 months (95% CI 4.068-7.932). The median progression-free survival (PFS) and overall survival (OS) were 5.0 months (95% CI 4.197-5.803) and 11.0 months (95% CI 7.398-14.602), respectively. Pemetrexed has comparable activity on brain lesions as on extracranial tumours in advanced lung adenocarcinoma patients with inoperable and asymptomatic BM.

    Metastatic dissemination represents the true cause of the malignant character of cancers. Its targeting is much more difficult than that of cell proliferation, because metastasis, like angiogenesis, involves a number of complex interactions between tumour and stroma; the contribution of adhesion and motility pathways is added to that of proliferation and survival pathways. Long distance extension, discontinuous in respect to the primitive tumour, is a major feature of cancer and the main cause of patients' death. Cancer cells use two main dissemination pathways: the lymphatic pathway, leading to the invasion of the lymph nodes draining the organs where the tumour evolves; and the blood pathway, leading to the invasion of distant organs such as liver, brain, bone or lung. Metastasis is inscribed within the properties of the primitive tumour, as shown by the comparative molecular analysis of the primitive tumour and its own metastases: their similarity is always more important than what could be expected from the general activation of "metastasis genes" or the inhibition of "metastasis suppressor genes". Among the signalling pathways involved in metastasis, one can mention the integrin pathway, the transforming growth factor beta (TGFβ) pathway, the chemokine pathway, the dependence receptor pathway and many others. These pathways allow the possibility of therapeutic targeting, thanks to therapeutic antibodies or small molecules inhibiting the kinases involved in these signalling pathways, but not a single properly anti-metastatic drug has yet been proposed: the complexity and the diversity of the processes allowing metastasis emergence, as well as the fact that the activation mechanisms are more often epigenetic than genetic and are generally physiological processes misled by the malignant cell, render especially difficult the therapeutic approach of metastasis.

    Study Design Retrospective study. Purpose To note the magnetic resonance imaging (MRI) differences between pathologically proven cases of atypical spinal tuberculosis and spinal metastasis in 40 cases. Overview of Literature Spinal tuberculosis, or Pott's spine, constitutes less than 1% of all cases of tuberculosis and can be associated with a neurologic deficit. Breast, prostate and lung cancer are responsible for more than 80% of metastatic bone disease cases, and spine is the most common site of bone metastasis. Thus, early diagnosis and prompt management of these pathologies are essential in preventing various complications. Methods We retrospectively reviewed 40 cases of atypical tuberculosis and metastasis affecting the spine from the year 2012 to 2014, with 20 cases each that were proven by histopathological examination. MR imaging was performed on 1.5 T MR-Scanner (Magnetom Avanto, Siemens) utilizing standard surface coils of spine with contrast injection. Chi-square test was used for determining the statistical significance and p-values were calculated. Results The most common site of involvement was the thoracic spine, seen in 85% cases of metastasis and 65% cases of Pott's spine (p=0.144). The mean age of patients with tubercular spine was found to be 40 years and that of metastatic spine was 56 years. The following MR imaging findings showed statistical significance (p<0.05): combined vertebral body and posterior elements involvement, skip lesions, solitary lesion, intra-spinal lesions, concentric collapse, abscess formation and syrinx formation. Conclusions Tuberculosis should be considered in the differential diagnosis of various spinal lesions including metastasis, fungal spondylodiskitis, sarcoidosis and lymphoma, particularly in endemic countries. Spinal tuberculosis is considered one of the great mimickers of disease as it could present in a variety of typical and atypical patterns, so proper imaging must be performed in order to facilitate

    Case 1 was a 62-year-old man who had performance status (PS) of 1 and stage IIIB adenocarcinoma of the lung. Because he showed progressive disease after induction chemoradiotherapy, he started to receive best supportive care alone. Three months after initial diagnosis, he complained of abdominal pain. As a result of computed tomography of the abdomen. He was diagnosed with abdominal pain probably caused by ileal perforation. An operation was undertaken and the surgical findings showed perforation by small intestine metastasis from lung adenocarcinoma. After the operation, he survived more than ten months. Case 2 was a 54-year-old man who had a PS of 3 and stage IV large cell carcinoma. After chemotherapy and sequential cranial radiotherapy, he developed anemia of unknown cause. He also complained of an abdominal pain during hospitalization and digestive tract perforation was diagnosed by a CT scan of the abdomen. He underwent surgery and the surgical findings showed a metastasis of large cell carcinoma in the small intestine. He died in a hospice two months after the operation. In the Japanese literature from 1983 to 2006. 48 operated cases with perforation caused by small intestine metastasis of lung cancer have been reported in full-length papers. Although the postoperative median survival time was 48 days, only one surgery-related death occurred. Patients who had a history of prior cancer treatment before surgery tended to achieve more prolonged survival compared to those who had not cancer treatment, probably due to poor PS. The preoperative PS may be one important prognostic factor in these patients.

    A 47-year-old man was referred to our hospital because of a 2-month history of dry cough, 2-kg weight loss, and a feeling of abdominal fullness. The PET-CT scan depicts the intense standard uptake values (SUVs) of the anterior and subphrenic lymphnodes, and intraperitoneal cavity, especially in the omentum, while, no uptake was found in the pleural cavity. Based on the pathological findings of the open lung biopsy specimens, he was diagnosed with malignant peritoneal mesothelioma of epithelioid type with thoracic metastasis. The present case demonstrated the some of the limitations of PET-CT in the diagnosis of malignant mesothelioma, which failed to detect pleural involvement despite aggressive invasion by this tumor.

    Mycosis fungoides is a common cutaneous T-cell lymphoma, which is usually characterized by chronic, indolence progression, with absence of typical symptoms in early stage, metastasis to lymph nodes, bone marrow and visceral organs in later stage and ultimately progression to systemic lymphoma. It can result in secondary skin infection which is a frequent cause of death. At present, no curative therapy existed. Therapeutic purpose is to induce remission, reduce tumor burden and protect immune function of patients. A case of patient with advanced severe mycosis fungoides receiving CHOP plus interferon α-2a was reported here, with disease-free survival of 7 months and overall survival of over 17.0 months, and current status as well as developments of mycosis fungoides were briefly introduced.

    Malignant mesonephric tumor (MMT) is a relatively uncommon malignancy of the female genital tract. The diagnosis of metastatic MMT is difficult because cytological, pathological, immunohistochemical characteristics of MMT are under-recognized. The authors present a 55-year-old female with metastatic pulmonary nodules. The bronchial washing cytology revealed three dimensional clusters of bland epithelial cells with slight nuclear grooves. A corresponding lung histology had ductal or tubular clusters of epithelial cells with intraglandular eosinophilic materials. These epithelial cells were positive for immunohistochemical stain of CD10, suggesting metastasis from MMT. The cervical smear showed clusters of bland, gland-forming epithelial cells with intraglandular eosinophilic materials. On histologic examination, mesonephric adenocarcinoma with papillary and solid proliferation was identified in the uterine cervix. A review of the literature for 72 cases of MMT is also included. Clinical and cytopathological features of MMT are herein made available. PMID:27172762

    Although signet-ring cell (SRC) adenocarcinoma is commonly seen in the stomach, it is a very rarely seen histologic entity in the bladder. It is difficult to distinguish primary SRC adenocarcinoma of the bladder from bladder metastasis of SRC carcinoma of the stomach only based on histological findings. In such cases, clinical findings and immunohistochemical studies may be helpful. We present here a 48-year-old male patient presenting with hematuria and abdominal pain. Computerised tomography of the patient revealed a gastric mass, peritoneal involvement, and thickening of the bladder wall, and histopathological analysis revealed SRC adenocarcinoma in both of the endoscopic biopsies taken from the stomach and bladder. Immunohistochemical analyses confirmed the diagnosis of SRC adenocarcinoma of the bladder secondary to gastric cancer. PMID:26346068

    A case of oesophageal basaloid carcinoma is reported. The disease was revealed as a brain metastasis and was found ad initium to be in an advanced stage, with evidence of brain, lung and liver metastasis. The treatment performed was palliative subtotal oesophagectomy followed by roentgen therapy. A year and a half later, the patient is still alive and in home care follow up. The authors end stressing this uncommon presentation for an oesophageal neoplasm and the rarity of its histologic type. They also stress the role of surgery, although palliative, in long survival, very unlike the rapid evolution of the few published cases.

  16. Pancreatectomy for metastasis to the pancreas from colorectal cancer and reconstruction of superior mesenteric vein: a case report

    PubMed Central

    2011-01-01

    Introduction Tumors of the pancreatic head can infiltrate the superior mesenteric vein. In such cases, the deep veins of the lower limbs can serve as suitable autologous conduits for superior mesenteric vein reconstruction after its resection. Few data exist, however, describing the technique and the immediate patency of such reconstruction. Case report We present the case of a 70-year-old Caucasian man with a metachronous metastasis of colon cancer and infiltration of the uncinate pancreatic process, on the anterior surface of which the tumor was located. En bloc resection of the tumor was performed with resection of the superior mesenteric vein and reconstruction. A 10 cm segment of the superficial femoral vein was harvested for the reconstruction. The superficial femoral vein segment was inter-positioned in an end-to-end fashion. The post-operative conduit patency was documented ultrasonographically immediately post-operatively and after a six-month period. The vein donor limb presented subtle signs of post-operative venous hypertension with edema, which was managed with compression stockings and led to significant improvement after six months. Conclusion In cases of exploratory laparotomies with high clinical suspicion of pancreatic involvement, the potential need for vascular reconstruction dictates the preparation for leg vein harvest in advance. The superficial femoral vein provides a suitable conduit for the reconstruction of the superior mesenteric vein. This report supports the uncomplicated nature of this technique, since few data exist about this type of reconstruction. PMID:21880120

    Purpose Patients with bone and brain metastases are among the most symptomatic nonemergency patients treated by radiation oncologists. Treatment should begin as soon as possible after the request is generated. We tested the hypothesis that the operational improvement method based on lean thinking could help streamline the treatment of our patients referred for bone and brain metastases. Methods University of Michigan Health System has adopted lean thinking as a consistent approach to quality and process improvement. We applied the principles and tools of lean thinking, especially value as defined by the customer, value stream mapping processes, and one piece flow, to improve the process of delivering care to patients referred for bone or brain metastases. Results and Conclusion The initial evaluation of the process revealed that it was rather chaotic and highly variable. Implementation of the lean thinking principles permitted us to improve the process by cutting the number of individual steps to begin treatment from 27 to 16 and minimize variability by applying standardization. After an initial learning period, the percentage of new patients with brain or bone metastases receiving consultation, simulation, and treatment within the same day rose from 43% to nearly 95%. By implementing the ideas of lean thinking, we improved the delivery of clinical care for our patients with bone or brain metastases. We believe these principles can be applied to much of the care administered throughout our and other health care delivery areas. PMID:20859409

    Cases of primary colorectal adenocarcinoma metastasized to the palatine tonsil are extremely rare. To the best of our knowledge, only 10 cases have thus far been previously documented in the English literature. A 37-year-old Chinese woman presented with a right palatine tonsil swelling and odynophagia 5 months after a surgical resection of rectal adenocarcinoma was performed. The patient underwent a tonsillectomy, and a metastatic poorly differentiated adenocarcinoma from a colorectal origin was revealed by immunohistochemical analysis. The manner in which tonsillar metastases are involved remains unknown and should be further studied. Here, we report a new case, briefly summarize these 10 cases and review the literature.

Here, we have described a gentle man who presented with the signs and symptoms of a mass lesion which was localized to the temporal lobe. The clinical examination and computerized tomography revealed the diagnosis of a temporal abscess. The loculated mass was tapped and it was sent for histopathology, which confirmed the presence of an organizing abscess. A laboratory investigation of the pus revealed Streptococcus pneumoniae. The treatment included total excision and the administration of prolonged antibiotics, which led to a good outcome in the patient. PMID:24086878

Intramedullary metastases are rare and represent only 4-8.5% of central nervous system metastases. An important feature of intramedullary metastases is the rapid progression of neurological deficits which necessitates rapid treatment.

    Merkel cell carcinoma is an aggressive neuroendocrine tumor occasionally demonstrating aberrant differentiation to other epithelial and nonepithelial cell lines. We describe a case of Merkel cell carcinoma displaying unique patterns of differentiation in the primary focus and brain metastasis. The skin primary was almost uniformly small cell carcinoma positive for epithelial and neuroendocrine markers, with a few glial fibrillary acidic protein- and cytokeratin 20-positive cells. The neoplasm contained giant cells immunoreactive for neurofilament and negative for epithelial markers. The neck lymph node metastasis was a typical neuroendocrine Merkel cell carcinoma positive for cytokeratin 20. A solitary dural intracranial metastasis displayed features of aggressive ganglioneuroblastoma, expressing many neuronal antigens with no evidence of glial or epithelial differentiation. After total gross resection, the tumor recurred within 3 months, and the patient developed skeletal metastases and died 6 months after craniotomy. PMID:24996688

    Brain metastases are a devastating consequence of cancer and currently there are no specific biomarkers or therapeutic targets for risk prediction, diagnosis, and treatment. Here the proteome of the brain metastatic breast cancer cell line 231-BR has been compared with that of the parental cell line MDA-MB-231, which is also metastatic but has no organ selectivity. Using SILAC and nanoLC-MS/MS, 1957 proteins were identified in reciprocal labeling experiments and 1584 were quantified in the two cell lines. A total of 152 proteins were confidently determined to be up- or down-regulated by more than twofold in 231-BR. Of note, 112/152 proteins were decreased as compared with only 40/152 that were increased, suggesting that down-regulation of specific proteins is an important part of the mechanism underlying the ability of breast cancer cells to metastasize to the brain. When matched against transcriptomic data, 43% of individual protein changes were associated with corresponding changes in mRNA, indicating that the transcript level is a limited predictor of protein level. In addition, differential miRNA analyses showed that most miRNA changes in 231-BR were up- (36/45) as compared with down-regulations (9/45). Pathway analysis revealed that proteome changes were mostly related to cell signaling and cell cycle, metabolism and extracellular matrix remodeling. The major protein changes in 231-BR were confirmed by parallel reaction monitoring mass spectrometry and consisted in increases (by more than fivefold) in the matrix metalloproteinase-1, ephrin-B1, stomatin, myc target-1, and decreases (by more than 10-fold) in transglutaminase-2, the S100 calcium-binding protein A4, and l-plastin. The clinicopathological significance of these major proteomic changes to predict the occurrence of brain metastases, and their potential value as therapeutic targets, warrants further investigation.

    Glioblastoma multiforme (GBM) is the most common malignant central nervous system tumor; however, extraneural metastasis is uncommon. Of those that metastasize extraneurally, metastases to the vertebral bodies represent a significant proportion. We present a review of 28 cases from the published literature of GBM metastasis to the vertebra. The mean age at presentation was 38.4 years with an average overall survival of 26 months. Patients were either asymptomatic with metastasis discovered at autopsy or presented with varying degrees of pain, weakness of the extremities, or other neurologic deficits. Of the cases that included the time to spinal metastasis, the average time was 26.4 months with a reported survival of 10 months after diagnosis of vertebral metastasis. A significant number of patients had no treatments for their spinal metastasis, although the intracranial lesions were treated extensively with surgery and/or adjuvant therapy. With increasing incremental gains in the survival of patients with GBM, clinicians will encounter patients with extracranial metastasis. As such, this review presents timely information concerning the presentation and outcomes of patients with vertebral metastasis. PMID:26704201

    Glioblastoma multiforme (GBM) is the most common malignant central nervous system tumor; however, extraneural metastasis is uncommon. Of those that metastasize extraneurally, metastases to the vertebral bodies represent a significant proportion. We present a review of 28 cases from the published literature of GBM metastasis to the vertebra. The mean age at presentation was 38.4 years with an average overall survival of 26 months. Patients were either asymptomatic with metastasis discovered at autopsy or presented with varying degrees of pain, weakness of the extremities, or other neurologic deficits. Of the cases that included the time to spinal metastasis, the average time was 26.4 months with a reported survival of 10 months after diagnosis of vertebral metastasis.

    Metastasis to the skeleton is uncommon in muscle-invasive carcinoma of the urinary bladder. When present, it most commonly involves the axial and proximal appendicular skeleton, and acrometastasis (metastasis to hand and foot) is very rare. We report a patient who developed a solitary metastatic lesion of the left metatarsal 2 weeks after radical cystectomy. The lack of suspicion and magnetic resonance imaging findings suggestive of inflammation led to a diagnosis of tubercular osteomyelitis and antitubercular therapy was started. The patient developed nodal metastasis and, because the foot lesion did not respond to treatment, fine needle aspiration cytology from it revealed poorly differentiated metastatic cancer.

    A 57-year-old female who had had a mixed tumor of the submandibular gland for 30 years presented with a cranial metastasis in the ipsilateral occipital region. Detailed histological examinations of the primary tumor failed to detect any carcinomatous component. In contrast, the metastasis contained a carcinomatous component. This histological discrepancy was confirmed by assessment of the expression of Ki-67 antigen in these tumor specimens and comparison with five typical benign mixed tumors. Cranial metastasis of a histologically benign mixed tumor is extremely rare, and a carcinomatous change in the metastatic tumor is apparently unique.

    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.

    Vulvar neoplasms represent four percent of all gynecological cancers. While most cases of vulvar neoplasms are benign, two percent of patients present with malignant disease. We present the case of a 37-year-old premenopausal female who presented to an outside institution with a lump in her left vulva, which had progressively enlarged to the size of an egg. A wide local excision of the left vulva was performed, and the pathology revealed a high-grade sarcoma, not otherwise specified (NOS), with negative margins. Imaging showed enlarged bilateral external iliac lymph nodes, likely metastatic. After discussion at a multidisciplinary gynecology oncology tumor board, she was treated with gemcitabine/docetaxel chemotherapy, followed by a left inguinal lymph node dissection and a left radical vulvectomy after being referred to our centre. The final pathology at that time showed a residual sarcoma of 3.5 mm in the left vulva with no lympho-vascular invasion (LVI) and negative margins, with the closest, laterally, at 2 mm. A total of three lymph nodes were negative. She received additional chemotherapy postoperatively. Approximately one year later, she returned to her gynecologist with a 1 cm mass on the left vulva. She underwent a left hemi-vulvectomy and lymph node dissection, and pathology confirmed the presence of a high-grade sarcoma with close margins. She received adjuvant radiotherapy. Three months later, she presented with persistent cough and pneumonia. Imaging revealed a 10 cm lung mass, which was believed to be metastasis from the vulva. This was confirmed with biopsy and was completely resected. Any mass in the Bartholin gland area should be investigated carefully. Poorly differentiated vulvar leiomyosarcoma in the Bartholin gland can recur locally but may also lead to distant metastasis. Despite surgical and systemic treatment, as well as adjuvant radiation, the tumor recurred. Due to the rarity of this condition, there are no clear recommendations for

    Tumor establishment, growth, and survival are supported by interactions with microenvironment components. Here, we investigated whether the interactions between prostate cancer cells and cortical astrocytes are associated to a potential role for astrocytes in tumor establishment. We demonstrate that astrocytes interact in vitro with prostatic cancers cells derived from different metastatic sites. Astrocytes and their secreted extracellular matrix, stimulate DU145 cell (a brain-derived prostate tumor cell line) proliferation while inhibiting cell death and modulating the expression of several genes related to prostate cancer progression, suggesting the activation of EMT process in these cells. In contrast, DU145 cells and their conditioned medium inhibited cell proliferation and induced cell death of astrocytes. On the other hand, the astrocytes were unable to significantly induce an increment of LNCaP cell (a lymph node-derived prostate tumor cell line) proliferative activity. In addition, LNCaP cells were also unable to induce cell death of astrocytes. Thus, we believe that DU145 cells, but not LNCaP cells, present an even more aggressive behavior when interacting with astrocytes. These results provide an important contribution to the elucidation of the cellular mechanisms involved in the brain microenvironment colonization.

    Cellular MRI involves sensitive visualization of iron-labeled cells in vivo but cannot differentiate between dead and viable cells. Bioluminescence imaging (BLI) measures cellular viability, and thus we explored combining these tools to provide a more holistic view of metastatic cancer cell fate in mice. Human breast carcinoma cells stably expressing Firefly luciferase were loaded with iron particles, injected into the left ventricle, and BLI and MRI were performed on days 0, 8, 21 and 28. The number of brain MR signal voids (i.e., iron-loaded cells) on day 0 significantly correlated with BLI signal. Both BLI and MRI signals decreased from day 0 to day 8, indicating a loss of viable cells rather than a loss of iron label. Total brain MR tumour volume on day 28 also correlated with BLI signal. Overall, BLI complemented our sensitive cellular MRI technologies well, allowing us for the first time to screen animals for successful injections, and, in addition to MR measures of cell arrest and tumor burden, provided longitudinal measures of cancer cell viability in individual animals. We predict this novel multimodality molecular imaging framework will be useful for evaluating the efficacy of emerging anti-cancer drugs at different stages of the metastatic cascade. PMID:27767185

    An unusual case of metastatic bronchioloalveolar carcinoma of the lung presented as a pituitary tumour in a young adult Chinese female, who subsequently died after having undergone trans-sphenoidal resection. Metastatic cancers of the pituitary are uncommon even in necropsy series and rarely give rise to clinical symptoms. This case draws attention to the fact that, although uncommon, pituitary metastases have been noted with increasing frequency and their distinction from primary pituitary tumours is often difficult. A metastatic pituitary tumour may be the initial presentation of an unknown primary malignancy, wherein the metastatic deposits may also be limited to the pituitary gland. Clinicians and pathologists alike should consider a metastatic lesion in the differential diagnosis of a non-functioning pituitary tumour. Images PMID:10070337

    Hepatic lesions represent a common finding in clinical practice. Bile ducts hamartomas, also known as Von Meyenburg complex, are benign hepatic malformations composed of small dilated cystic bile ducts lined by fibrous stroma. They represent a rare and asymptomatic clinic-pathological entity. Imagiological findings are variable, and may present as multiple small scattered lesions, or rarely as a single nodule. These findings may resemble secondary lesions and, although benign, there are cases of progression to colangiocarcinoma. Thus it is important to include this complex in the differential diagnoses of focal hepatic lesions, being necessary a detailed investigation for their differentiation. This case represents an atypical presentation of a rare and not frequently considered entity in clinical practice.

    Renal cell carcinoma (RCC) may metastasize to mediastinal lymph nodes without any abdominal lymph node involvement. The present study describes an autopsy-proven case of RCC presenting with a large mediastinal mass; the case had been previously misdiagnosed as small cell lung carcinoma due to imaging analysis results, an elevated serum level of neuron-specific enolase and the presence of small atypical cells with a high nuclear/cytoplasmic ratio. Despite RCC occurrence being rare, it should be considered in the differential diagnosis, particularly when a mass located in the kidneys presents with metastases to the mediastinal lymph nodes, even if there is no involvement of the abdominal lymph nodes and the primary lesion is of a small size.

After adjuvant chemotherapy, radiotherapy and trastuzumab, she was admitted to hospital with the complaints of headache on February 2012. The magnetic resonance imaging (MRI ) revealed multiple brain metastasis. Whole brain radiotherapy and palliative chemotherapy were applied to the patients. In follow-up, on ophthalmological examination, there was a solid lesion on iris. The orbital MRI was performed and it revealed the thickness on iris of left eye. After diagnostic procedure final pathological rewiev reported that invasive ductal carcinom metastasis. Iris metastasis may be considered by MRI findings following: The thickness on iris and contrast enhanced lesion.

A roentgenogram of the right thigh, technetium-99m phosphate bone scintigraphy and combined 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography imaging were performed, and the results revealed multiple osteolytic lesions in the humerus bilaterally, the right scapula and the right femur. The lesions were suspected to be colon cancer metastases. To improve the quality of life of the patient, palliative surgery was performed. However, the intraoperative biopsy of the focal lesions and immunohistochemical evaluation revealed multiple myeloma (MM). Chemotherapy was administered 2 weeks after surgery and the patient recovered uneventfully. The manifestations of MM and bone metastases are occasionally similar. Although the coexistence of the two diseases is rare, both conditions should be considered in the differential diagnosis of osteolytic lesions. PMID:26870352

The histopathological diagnosis was poorly differentiated adenocarcinoma, ss, ly3, v1, n2 (+), and stage IIIa. Postoperative adjuvant chemotherapy consisted of short-term intravenous infusion of 5-FU, 320 mg/m2/day (= 480 mg/body) for 5 days beginning on postoperative day (POD) 1, and oral 5-FU, 200 mg/day, for 1 year beginning on POD 14. The preoperative CEA value was 316.2 ng, but it fluctuated below 10 ng postoperatively. About one year after the operation, the patient began to complain of epigastric pain, loss of appetite, and general malaise. CT of the upper abdomen revealed a 1.5-cm para-aortic lymph node, and the CEA value of 319.0 ng was abnormally high. 5-FU was stopped, oral UFT at 300 mg/day was started, and the patient's course was followed. Three months after the start of UFT, the lymph node had shrunk on CT (shrinkage rate: 66.7%), and the CEA value had decreased to 14.3 ng. As though corresponding to these changes there was a gradual decrease in the epigastric pain, general malaise, etc., and the patient's appetite also returned. There were no subsequent elevations in the CEA values or increases in the size of the para-aortic lymph nodes, and the patient's general condition was favorably maintained.

The latter arises in the midline, most often in the pineal gland, less frequently in the suprasellar or parasellar region. The outcome is usually fatal because of secondary spinal dissemination. We report 10-year-old boy presented with a right eye proptosis and leukocoria, and the magnetic resonance imaging (MRI) showed right orbital mass lesion infiltrating optic nerve and diagnosis of retinoblastoma was made. He was referred for fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) to find out the extent of the disease. PET/CT showed abnormal FDG-uptake within right orbital mass lesion, suprasellar enhancing lesion and drop metastasis in the cervical spinal canal level. He was diagnosed as a case of TRb with spinal canal drop metastasis. He underwent chemotherapy and craniospinal irradiation.

    Serotonin syndrome is a potentially life-threatening reaction that occurs in patients using drugs that elevate the serotonin level in the body. Excess serotonergic activity in the CNS and peripheral serotonin receptors results in neuromuscular hyperactivity, mental changes and autonomic symptoms. Hyperthermia is a characteristic feature of the syndrome. We describe neuropathological findings from two cases of lethal serotonin syndrome, both patients presenting with hyperthermia and neuromuscular symptoms. One of the patients had been taking amitriptylin and mirtazapin and the other had used amitriptylin and citalopram. They died, respectively, 10 days and 2½ months after the onset of serotonin syndrome symptoms. Post-mortem examination of the brains showed subtotal loss of cerebellar Purkinje cells in both cases. In the case with shorter survival time, areas with partial loss of cerebellar granule cells were observed, whereas in the case with longer survival time general and extensive loss of granule cells was found. Cells in other areas of the brain known to be sensitive to hypoxic injury were not affected. Selective loss of Purkinje cells has previously been described in neuroleptic malignant syndrome and heatstroke, conditions that are characterized by hyperthermia. This suggests that hyperthermia may be a causative factor of brain damage in serotonin syndrome. This is the first report describing neuropathological findings in serotonin syndrome.

    There is ongoing research in relating the concentration of elements in the brain with Alzheimer`s disease. The presence of particular elements, such as aluminum and vanadium, has been considered as a possible environmental factor, creating significant interest and controversy in the field. We have been analyzing brain tissue from the MRC Alzheimer`s Disease Brain Bank, Institute of Psychiatry, from a number of cortical regions of the brain, namely, the frontal, occipital, parietal, and temporal lobes, as well as from the left and right hemispheres of the same brain whenever possible. The techniques employed have been proton-induced X-ray emission (PIXE) analysis, proton-induced gamma-ray emission (PIGE) analysis, Rutherford backscattering (RBS), and instrumental neutron activation analysis. Neutron irradiations were carried out at the Imperial College Consort II reactor, whereas for PIXE, PIGE, and RBS, the University of Surrey Accelerator Laboratories were used employing a Van de Graaff accelerator. In this paper, we present the cadmium results from the frontal lobe of Alzheimer cases and controls determined by PIXE analysis.

    A resected case of huge liver metastasis of hepatoid adenocarcinoma of the lung is described. A 77-year-old man who presented a solitary huge liver tumor was admitted to our hospital. He had undergone right lower lobectomy of the lung for lung cancer one year before. The view of imaging studies was not a typical one of hepatocellular carcinoma. Serum levels of AFP and PIVKA-II were 334,500ng/mL and 3,890mAU/mL, respectively, and the proportion of AFP L3 was 97.9%. It was thought that they were strongly diagnostic for hepatocellular carcinoma. Extended right lobectomy of the liver was performed. Microscopically, it was poorly differentiated adenocarcinoma and diagnosed as liver metastasis from the formerly resected lung cancer. The tumor was composed of cells with both sheet-like growth and tubule formation. The neoplastic cells, in the sheet-like growth resembled hepatocellular carcinoma cells. By immunohistochemical staining with anti-AFP and anti-PIVKA-II antibodies, cancer cells of both the primary and metastatic lesions were positive. The patient eventually died of multiple liver and bone metastasis 6 months after the operation.

    Differentiated thyroid cancer is, usually, associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual. Only few cases of papillary carcinoma with axillary nodal metastasis were previously reported in the literature. We present a 38-year-old female who underwent Iodine-131 whole-body scintigraphy, after total thyroidectomy and bilateral neck lymph node dissection for papillary carcinoma of thyroid, showed intense uptake in the remnant thyroid, lung metastasis, left cervical and left axillary lymph nodes. Excision of left axillary lymph nodes confirmed metastatic papillary carcinoma. PMID:25829741

    Merkel cell carcinoma (MCC) is a rare cutaneous cancer of neuroendocrine cell origin that occurs frequently on the head and neck. With a high incidence of local recurrence and regional and distant metastasis, it carries a poor prognosis. We performed a retrospective study to determine the prognostic implications of parotid gland metastasis in MCC of the head and neck. Our study population was made up of 14 patients-13 men and 1 woman, aged 62 to 87 years (mean: 75.9)-who underwent a parotidectomy for the diagnosis of MCC over a period of 10 years and 9 months. Ten patients had a primary skin lesion of the head and neck and 4 presented with a parotid mass and an unknown primary. In all, 13 of the 14 patients were found to have parotid involvement-either a direct extension of MCC into the gland or a positive intraparotid lymph node; some patients had both. All patients underwent tumor excision, and 10 underwent neck dissection. Eleven patients received adjuvant radiotherapy; none received adjuvant chemotherapy. Of the 10 patients who underwent a neck dissection, 6 were found to have a cervical lymph node metastasis on pathologic examination. Follow-up ranged from 1.3 to 39.2 months (mean: 12.4). Three patients were lost to follow-up shortly after surgery, although some information was available on 2 of them. At the final follow-up, mortality data were available on 12 patients; of these, 11 had died. The lone survivor was the patient without a parotid metastasis. Among those known to have died, survival ranged from 1.6 to 49.2 months (mean: 16.0). We conclude that parotid metastasis in patients with MCC of the head and neck is associated with a dismal survival rate that is even worse than the poor survival associated with cervical node involvement.

    Purpose/Objectives: The aim of this study was to evaluate the impact of definitive thoracic chemoradiation therapy following surgery or stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) on the outcomes of patients with non-small cell lung cancer (NSCLC) with synchronous solitary brain metastasis (SSBM). Methods and Materials: A total of 63 NSCLC patients with SSBM were retrospectively evaluated. Patients were staged using positron emission tomography-computed tomography in addition to conventional staging tools. Thoracic radiation therapy (TRT) with a total dose of 66 Gy in 2 Gy fractions was delivered along with 2 cycles of cisplatin-based chemotherapy following either surgery plus 30 Gy of WBRT (n=33) or SRS plus 30 Gy of WBRT (n=30) for BM. Results: Overall, the treatment was well tolerated. All patients received planned TRT, and 57 patients (90.5%) were also able to receive 2 cycles of chemotherapy. At a median follow-up of 25.3 months (7.1-52.1 months), the median months of overall, locoregional progression-free, neurological progression-free, and progression-free survival were 28.6, 17.7, 26.4, and 14.6, respectively. Both univariate and multivariate analyses revealed that patients with a T1-T2 thoracic disease burden (P=.001), a nodal stage of N0-N1 (P=.003), and no weight loss (P=.008) exhibited superior survival. Conclusions: In the present series, surgical and radiosurgical treatments directed toward SSBM in NSCLC patients were equally effective. The similarities between the present survival outcomes and those reported in other studies for locally advanced NSCLC patients indicate the potentially curative role of definitive chemoradiation therapy for highly selected patients with SSBM.

    Intramuscular myxoma (IMM) as a rare soft-tissue tumor arising from the muscles is completely benign. When IMM accompanies malignance, it may be misdiagnosed as muscle metastasis, and for this extremely rare concurrence, the subsequent treatment would vary accordingly. The current study presents, to the best of our knowledge, the first case of non-small cell lung cancer (NSCLC) concomitant with IMM mimicking skeletal muscle metastasis. A 64-year-old female was hospitalized with a history of chest discomfort and right lumbar pain that had persisted for four months. The computed tomography scan showed a lesion in the left upper lobe of the lung and the right psoas, respectively. Serum biomarkers for NSCLC were abnormal. A presumptive clinical diagnosis was compatible with left NSCLC and right psoas muscle metastasis (cT2aN3M1b, stage IV). Stage IV lung cancer would receive palliative treatment. However, the final diagnosis of synchronous left lung squamous cell carcinoma (cT2aN3M0, stage IIIB) and IMM in the right psoas was confirmed by biopsy. The patient therefore underwent definitive chemoradiotherapy for lung carcinoma, and conservative treatment, including analgesics, for IMM. The diagnosis process for a malignant neoplasm concomitant with IMM is not straightforward due to a lack of clinical experience, and it significantly affects the tumor staging and subsequent treatment strategy. The present case suggests that IMM should be included in the differential diagnosis when an abnormal intramuscular lesion concomitant with malignancy is identified. The value of histopathological diagnosis prior to definitive treatment also requires highlighting. PMID:26722289

    Background: Lymphomatoid granulomatosis is a rare disorder of the central nervous system (CNS) with few cases being reported in literature. We present the case of an adult with an unusual lesion of the CNS who presented with motor seizures and was diagnosed with lymphomatoid granulomatosis, followed by a discussion of the process of evaluation and management. Case Description: A 42-year-old male presented with motor seizures and loss of consciousness for 10 minutes along with dysarthria and left hemiplegia. Neurological examination and imaging with magnetic resonance imaging (MRI) of the brain revealed a mass in the right striatum. The patient was hospitalized and underwent an image-guided right frontal craniotomy using the Leksell Stereotactic G-Frame. Pathology reported a lymphomatoid granulomatosis. Being immunocompetent, the patient received medical treatment with prednisone and rituximab. Two years after his diagnosis, the patient had no active disease and his brain MRI did not show contrast enhancement. After almost 3 years of follow-up, the patient has a mild weakness in the left-side of his body (4/5), is seizure-free, and can walk and perform daily activities. Conclusions: This rare lesion in an adult, immunocompetent patient, debuting with motor seizures represents a challenge in terms of diagnosis and treatment. After surgical and medical treatment, the patient had a satisfactory recovery. Clinical features, imaging, differential diagnosis, and pathology are discussed.

    Toxoplasmosis is a common disease in Latin America. The infection has a major impact on public health worldwide. Congenital toxoplasmosis is part of the spectrum of the disease and the consequences for the newborn are devastating. In this article, we present a case of brain calcifications and hydrocephalus secondary to infection with Toxoplasma gondii in a newborn, as well as the outcome during follow-up and long-term sequelae. It is of high importance for the clinician to think about this disease, due to its high prevalence in Latin America, and to adopt adequate measures for its prevention and timely management in order to reduce long-term sequelae.

    We present a successful case of treatment of colonic metastasis and peritoneal recurrence of type 4 gastric cancer by using colectomy and chemotherapy. A 70-year-old woman with a diagnosis of type 4 advanced gastric cancer underwent distal gastrectomy. The final pathological diagnosis was LM, circ, type 4, sig, pT4a (SE), ly1, v1, pN1, M0, P0, CY0, pStage Ⅲa. Adjuvant chemotherapy was conducted with oral administration of S-1, though regrettably the chemotherapy was interrupted because of diarrhea, an adverse effect of S-1. Metastatic recurrence occurred on the transverse colon, for which she underwent transverse colectomy 2.9 years after the initial surgery. Another colonic metastasis in the ascending colon along with peritoneal recurrence was diagnosed 3.11 years after the initial surgery, and the patient underwent a palliative colostomy and received chemotherapy with S-1 plus docetaxel. She was successfully treated up to a clinical CR with chemotherapy, and she died 5.10 years after the initial surgery. In this case, a good prognosis was obtained through the combination of resection of the recurrence sites, palliative surgery for avoiding obstruction, and chemotherapy using S-1 plus docetaxel for metachronous multiple metastases.

  11. Acromegaly resolution after traumatic brain injury: a case report

    PubMed Central

    2014-01-01

    Introduction Anterior hypopituitarism is a common complication of head trauma, with a prevalence of 30% to 70% among long-term survivors. This is a much higher frequency than previously thought and suggests that most cases of post-traumatic hypopituitarism remain undiagnosed and untreated. Symptoms of hypopituitarism are very unspecific and very similar to those in traumatic brain injury patients in general, which makes hypopituitarism difficult to diagnose. The factors that predict the likelihood of developing hypopituitarism following traumatic brain injury remain poorly understood. The incidence of a specific hormone deficiency is variable, with growth hormone deficiency reported in 18% to 23% of cases. Case presentation A 23-year-old Hispanic man with a 2-year history of hypertension and diabetes presented with severe closed-head trauma producing diffuse axonal injury, subarachnoid hemorrhage and a brain concussion. A computed tomography scan showed a pituitary macroadenoma. The patient has clinical features of acromegaly and gigantism without other pituitary hyperfunctional manifestations or mass effect syndrome. A short-term post-traumatic laboratory test showed high levels of insulin like growth factor 1 and growth hormone, which are compatible with a growth hormone–producing pituitary tumor. At the third month post-trauma, the patient’s levels of insulin like growth factor 1 had decreased to low normal levels, with basal low levels of growth hormone. A glucose tolerance test completely suppressed the growth hormone, which confirmed resolution of acromegaly. An insulin tolerance test showed lack of stimulation of growth hormone and cortisol, demonstrating hypopituitarism of both axes. Conclusion Even though hypopituitarism is a frequent complication of traumatic brain injury, there are no reports in the literature, to the best of my knowledge, of patients with hyperfunctional pituitary adenomas, such as growth hormone–producing adenoma, that resolved

    We present a rare case of a non-fatal impalement injury of the brain. A 13-year-old boy was found in his classroom unconsciously lying on floor. His classmates reported that they had been playing, and throwing building bricks, when suddenly the boy collapsed. The emergency physician did not find significant injuries. Upon admission to a hospital, CT imaging revealed a "blood path" through the brain. After clinical forensic examination, an impalement injury was diagnosed, with the entry wound just below the left eyebrow. Eventually, the police presented a variety of pointers that were suspected to have caused the injury. Forensic trace analysis revealed human blood on one of the pointers, and subsequent STR analysis linked the blood to the injured boy. Confronted with the results of the forensic examination, the classmates admitted that they had been playing "sword fights" using the pointers, and that the boy had been hit during the game. The case illustrates the difficulties of diagnosing impalement injuries, and identifying the exact cause of the injury. PMID:27555425

    Anaplastic large cell lymphoma (ALCL) is a subtype of non-Hodgkin lymphoma composed of CD30-positive cells and now recognized as three different entities: primary cutaneous ALCL, primary systemic anaplastic lymphoma kinase (ALK)-positive (ALK+) ALCL and primary ALK-negative (ALK-) ALCL. ALK+ ALCL is supposed to have a better prognosis than ALK- ALCL. It is rarely metastasized to other sites, especially to the central nervous system (CNS). Herein, we present a rare case of systemic ALK+ ALCL which metastasized to the brain after a long-term disease free survival in an adult. Neuroimaging revealed a well-enhanced mass in the left frontal lobe. And it was completely resected. The results of the pathological and immunohistochemical studies were consistent with the metastasized ALK+ ALCL. The clinical findings, pathologic characteristics and treatment are described.

    Small-cell lung cancer is a highly aggressive carcinoma, with poorer prognosis in patients with brain metastases. We present the case of a 49-year-old woman diagnosed with a cerebellar tumour which, following surgery, was revealed to be a metastatic small-cell lung carcinoma. Subsequent CT and PET scanning showed a small, isolated 8 mm nodule in the upper lobe of the right lung. The patient was suffering from schizophrenia and has been treated with clozapine for 17 years. Because of the unusual presentation, there was no therapy given for the primary tumour at the time, and systemic therapy or surgery was discussed. However, 18 months later, the nodule was slightly larger (14 mm), and surgery was performed. On pathology examination, the tumour was presented as a typical small-cell carcinoma. Standard chest irradiation with systemic chemotherapy was given. At the time of writing, 39 months after diagnosis of metastatic small-cell carcinoma, the patient is disease free. However, this case is unusual in that a long-term observation of a small stable primary tumour in the lung took place without any therapy being given. This case strongly supports the thesis that small-cell lung cancer may comprise a heterogeneous group of tumours with different biological properties. The proapoptotic effect of clozapine may be also taken into account.

    The authors review a case of a 24-year-old male patient hospitalised for repeated acute abdominal symptoms. His medical history included no diseases worth of mentioning. By imaging techniques (abdominal US and CT scan) a cystic lesion, measuring 40 x 35 x 30 mm in diameter was found, and was diagnosed as pseudocyst in the region of the tail of the pancreas. Jejunal feeding was introduced. The lesion did not improve and the second CT scan suggested a suspicion of pancreatic cystadenoma. Three months after first presentation the surgical resection was performed. The tumour, however, was found independent of the pancreas (90 x 80 x 50 mm). Both histologically and immunohistochemically the lesion proved to be the metastasis of a germ cell (yolk-sac) tumour. Following the morphological diagnosis, detailed urological and medical check up was performed. A previously nonpalpable small tumour was found in the left testis which was radically resected. The testicular tumour measuring 9 x 9 x 5 mm in diameter was diagnosed as embryonal carcinoma. Later on the patient underwent chemotherapy. He has been undergoing close oncological followup. Clinically, he is disease free. Authors emphasize the importance of imaging techniques and fine needle aspiration cytology in the case of retroperitoneal masses in young males. The possibility of a metastasis, especially of germ cell origin, should be excluded (not only by physical examination, but by ultrasound of testis also) in case of retroperitoneal cystic tumours even with unusual morphology.

    Neuroendocrine carcinomas (NEC) of the female genital tract are aggressive and rare tumors that usually involve the cervix and ovary, and are seen rarely in the endometrium in perimenopausal or postmenopausal women. We presented a case of a73 year-old postmenopausal woman with vaginal bleeding and abdominal pain. A subsequent computerized tomography (CT) scan of pelvis showed an enlarged uterus (20,0 × 12,0 cm) with para-aortic and pelvic lymph node metastases. She underwent surgical debulking and staging of an endometrial tumor with omental metastasis and positive lymph nodes. The pathological diagnosis was primary small cell carcinoma (SCC) combined with endometrioid carcinoma of uterine corpus. Her final FIGO stage was IVB. Three months after surgery CT-total body showed a metastasis to left lung of SCC. Because the small-cell component of endometrial tumor showed a strong positivity for TTF1 as pulmonary counterpart a differential diagnosis with a primary small cell carcinoma of the lung should be made. Identifying an appropriate therapeutic management for SCC of endometrium is challenging since these are extremely rare tumors. An optimal initial therapeutic approach to this rare disease, especially at an advanced stage, has not yet been clearly defined. However, in these a multidisciplinary therapy, including surgery, chemotherapy, and radiotherapy represent until this time the only therapeutic option. PMID:26900464

    An exploratory study of brain tumors in adults was carried out using 215 cases diagnosed in Southern Ontario between 1979 and 1982, with an individually matched, hospital control series. Significantly elevated risks were observed for reported use of spring water, drinking of wine, and consumption of pickled fish, together with a significant protective effect for the regular consumption of any of several types of fruit. While these factors are consistent with a role for N-nitroso compounds in the etiology of these tumors, for several other factors related to this hypothesis, no association was observed. Occupation in the rubber industry was associated with a significant relative risk of 9.0, though no other occupational associations were seen. Two previously unreported associations were with smoking nonfilter cigarettes with a significant trend and with the use of hair dyes or sprays. The data do not support an association between physical head trauma requiring medical attention and risk of brain tumors and indicate that exposure to ionizing radiation and vinyl chloride monomer does not contribute any appreciable fraction of attributable risk in the population studied. The findings warrant further detailed investigation in future epidemiologic studies.

    A 60-year-old woman was diagnosed as having liver metastasis from gastric cancer 14 months after total gastrectomy and total pancreatectomy. The liver tumor was so huge and the complication, diabetes mellitus, was so severe that she was palliatively treated by hyperthermo-chemo-radiotherapy (HCR therapy) with 8-MHz capacitive heating system. Because hyperthermia for deep seated tumor is very difficult, irradiation (10 MV X-ray, 36 Gy) and systemic chemotherapy (CDDP, MMC) were combinedly used. After 10 session of hyperthermia, the tumor showed a remarkable regression in size, followed by S8 subsegmentectomy of the liver. Histologically, cancer cells were still viable in the midst of fibrosis around coagulation necrosis, while normal liver cells remained intact. Multidisciplinary HCR therapy is quite a useful modality for liver tumors and may serve to expand the indication for surgical operation.

    It is very rare that ovarian carcinoma metastasizes to the pancreas, and pathological diagnosis is required to confirm the primary site. The present study reported a 73-year-old woman with serous carcinoma of the ovary that metastasized to the tail of the pancreas. Metastasis was confirmed by pathological and immunohistochemical examination of a biopsy of the ovarian tumor, an endoscopic ultrasound-guided fine-needle aspiration biopsy of the pancreatic tumor and computerized tomography-guided paraaortic lymph node biopsy. A biopsy of the ovarian tumor is useful to make a precise diagnosis and to determine proper treatment when ovarian and pancreatic tumors are identified at the same time and the primary neoplasm is uncertain.

    The occurrence of central nervous system metastases in ovarian cancer patients ranges from 0.88 to 4.5%. Centra nervous system involvement in a fallopian tube carcinoma is extremely rare. A 77-year-old woman with an invasive tubal carcinoma was admitted because of ophthalmoplegia, sparing the lateral rectus muscle of the left eye, a decreased left corneal reflex and hypoesthesia along the distribution of the ophthalmic and maxillary branches of the left trigeminal nerve. CT scan showed a space occupying lesion in the left sphenoid sinus invading the left cavernous sinus and the submucosa of the left lateral wall of the nasopharynx, proven histologically to be a metastasis from her primary cancer. Attention should be paid to the possibility of distant and unusual metastases associated with tubal cancer in order to treat the patients promptly. PMID:8171748

    Three pediatric patients with infratentorial metastatic non-epithelial malignant brain tumors were successfully treated by radical surgical resection followed by aggressive radiochemotherapy. One patient with neuroblastoma and two with rhabdomyosarcoma were successfully treated by first line multimodal treatments, but developed infratentorial metastasis after several months of remission. All patients revealed intracranial metastases manifesting as rapidly progressing neurological symptoms caused by mass effect in the posterior fossa. Radical surgical resection was performed without morbidity. The patients were then treated by adjuvant radiochemotherapy with or without autologous peripheral blood stem cell transplantation, resulting in complete remission. Two patients developed extracranial recurrences 4 months after the treatments for intracranial metastases. One patient was treated by second high-dose chemotherapy with allogeneic cord blood transplantation, again resulting in complete remission. Another patient was treated by second chemotherapy and maintaining stable disease. The other patient maintained complete remission. All three patients were alive without neurological deficit for 8, 11, and 12 months after diagnosis of brain metastasis. Patients with infratentorial brain metastases of highly malignant pediatric non-epithelial tumors are in a severe clinical state, but still can have longer and useful lives with aggressive multimodal treatments combined with radical surgical resection.

    A 57-year-old man was admitted because of abdominal fullness. An abdominal ultrasonographic study disclosed multiple space-occupying lesions (SOL) in the liver. On blood examinationC the serum levels of CEA and CA19-9 were significantly high while those of AFP and SCC were within normal ranges. Endoscopically biopsied specimens of the lower esophagus histologically revealed poorly differentiated squamous cell carcinoma. Pathohistologically similar findings were obtained from the needle biopsied specimen of the SOL in the liver. Thus the patient was diagnosed as having squamous cell carcinoma of the esophagus with liver metastasis. On the 41st hospital day the patient died and an autopsy was performed. Although multiple metastases were recognized, cancer cells were limited within the submucosa of the esophagus. Immunostaining of CEA and CA19-9 was positive on the carcinoma cells both in the esophagus and the liver. Thus a relation between the biological malignancy of esophageal cancer and serum levels of CEA and CA19-9 was suggested.

    A 71-year-old man presented with chief complains of hoarseness and dysphagia. He was diagnosed to have an advanced esophageal adenocarcinoma in the middle thoracic esophagus for which chemoradiation therapy was started. Partial response was observed and he was referred to our hospital thereafter. After detailed examination, he underwent a subtotal esophagectomy followed by two-field lymphadenectomy in May 2001. Histopathological examination revealed a complete response. Ten months later, hematological examination showed a high serum CEA level and CT scan disclosed mediastinal lymph node recurrences. He received a course of systemic chemotherapy so called FP therapy and five months later, a course of combination chemotherapy with 700 mg/m2 5-FU on days 1-5 and 70 mg/m2 nedaplatin on day 1 was administered. Because the high serum CEA level sustained afterward, FDG-PET was undertaken in March 2003. The right adrenal gland showed an intense abnormal FDG uptake and CT scan detected a low density mass in the area. Since no metastases could be identified in other sites, right adrenalectomy was performed. Pathological finding was poorly-differentiated tubular adenocarcinoma. Five years and eleven months after adrenalectomy, he died of pneumonia with no signs of recurrence. Surgical resection may contribute to improving the prognosis of solitary adrenal metastasis of esophageal cancer without the other noncurative factors.

    Purpose: The use of prophylactic cranial irradiation (PCI) in small cell lung cancer (SCLC) with surgical resection has not been fully identified. This study undertook to assess the factors affecting the risk of brain metastases in patients with stage I-III SCLC after surgical resection. The implications of PCI treatment for these patients are discussed. Methods and Materials: One hundred twenty-six patients treated with surgical resection for stage I-III SCLC from January 1998-December 2009 were retrospectively analyzed to elucidate the risk factors of brain metastases. Log-rank test and Cox regression model were used to determine the risk factors of brain metastases. Results: The median survival time for this patient population was 34 months, and the 5-year overall survival rate was 34.9%. For the whole group, 23.0% (29/126) of the patients had evidence of metastases to brain. Pathologic stage not only correlated with overall survival but also significantly affected the risk of brain metastases. The 5-year survival rates for patients with pathologic stages I, II, and III were 54.8%, 35.6%, and 14.1%, respectively (P=.001). The frequency of brain metastases in patients with pathologic stages I, II, and III were 6.25% (2/32), 28.2% (11/39), and 29.1% (16/55) (P=.026), respectively. A significant difference in brain metastases between patients with complete resection and incomplete resection was also observed (20.5% vs 42.9%, P=.028). The frequency of brain metastases was not found to be correlated with age, sex, pathologic type, induction chemotherapy, adjuvant chemotherapy, or adjuvant radiation therapy. Conclusions: Stage I SCLC patients with complete resection had a low incidence of brain metastases and a favorable survival rate. Stage II-III disease had a higher incidence of brain metastases. Thus, PCI might have a role for stage II-III disease but not for stage I disease.

    Penetrating brain injury(PBI)is very rare in Japan. Because there is a very wide variety of pathological condition of PBI, the guideline for the treatment of PBI has not been established yet. We report the unique case of PBI caused by a steel wire piece completely embedded in the brain parenchyma. A 75-year-old man was brought to the emergency department due to ocular injury caused by a steel wire piece. Neurological examination revealed only left visual disturbance. CT scan revealed a steel wire piece located intraparenchymally between the left frontal lobe and the ventricles, but digital subtraction angiography showed no significant vascular injury in the surrounding structures. We performed an open surgery and removed the steel wire piece. Because the steel wire piece was completely embedded in the brain, we used intraoperative X-ray fluoroscopy to choose a less invasive approach for the brain. The patient suffered no additional neurological deficit and no sign of cerebral infection or seizure after surgery. He was discharged after a 4-week administration of antibiotics. In most cases of PBI caused by low velocity injury, foreign bodies are not completely embedded in the brain except for remnants after surgical removal. This is the first report of low velocity PBI caused by a foreign body completely embedded in the brain.

    Frontotemporal dementia (FTD) is a clinical syndrome characterized by progressive decline in social conduct and a focal pattern of frontal and temporal lobe damage. Its biological basis is still poorly understood but the focality of the brain degeneration provides a powerful model to study the cognitive and anatomical basis of social cognition. Here, we present Dr. A, a patient with a rare hereditary bone disease (hereditary multiple exostoses) and FTD (pathologically characterized as Pick's disease), who presented with a profound behavioral disturbance characterized by acquired sociopathy. We conducted a detailed genetic, pathological, neuroimaging and cognitive study, including a battery of tests designed to investigate Dr. A's abilities to understand emotional cues and to infer mental states and intentions to others (theory of mind). Dr. A's genetic profile suggests the possibility that a mutation causing hereditary multiple exostoses, Ext2, may play a role in the pattern of neurodegeneration in frontotemporal dementia since knockout mice deficient in the Ext gene family member, Ext1, show severe CNS defects including loss of olfactory bulbs and abnormally small cerebral cortex. Dr. A showed significant impairment in emotion comprehension, second order theory of mind, attribution of intentions, and empathy despite preserved general cognitive abilities. Voxel-based morphometry on structural MRI images showed significant atrophy in the medial and right orbital frontal and anterior temporal regions with sparing of dorsolateral frontal cortex. This case demonstrates that social and emotional dysfunction in FTD can be dissociated from preserved performance on classic executive functioning tasks. The specific pattern of anatomical damage shown by VBM emphasizes the importance of the network including the superior medial frontal gyrus as well as temporal polar areas, in regulation of social cognition and theory of mind. This case provides new evidence regarding the

    Metastasis to the adrenal glands is a relatively frequent observation at autopsy of patients that have succumbed to cancer. Long-term disease-free survival has been reported in patients following the resection of solitary adrenal metastasis resulting from colorectal cancer. In addition, following primary resection for colorectal cancer, solitary metastasis to the adrenal glands is rare, even in outpatients at routine follow-ups. Therefore, adrenal metastasis is usually detected in combination with multiple synchronous metastases at other sites in the terminal stages of cancer. Between 1998 and 2002, 3 patients with adrenal metastasis and other synchronous metastatic sites underwent surgery for adrenal metastasis at the Department of Gastroenterological Surgery at Osaka University. The other synchronous metastatic sites observed in the 3 patients consisted of lung and para-aortic lymph nodes. In total, 2 out of the 3 patients experienced long-term disease-free survival for >5 years following surgery and 1 patient underwent curative resection for recurrence of metastases in the liver and right adrenal gland 79 months subsequent to the initial resection for adrenal metastasis. All 3 patients survived for >90 months. In conclusion, aggressive surgical resection for adrenal metastasis and other metastatic sites resulting from colorectal cancer may result in a survival benefit in selected patients. PMID:27602101

    Malignant epithelioid hemangioendothelioma (MEH), or high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy. A few cases of MEH have been documented in the head and neck region, including the neck, thyroid gland, larynx and scalp. MEHs are extremely rare in the oral cavity. Only 31 cases of MEH in the oral cavity were described in English literature between 1975 and 2014. Further, only eleven cases were referred to MEH of the maxillary or mandibular gingiva. No gingival MEH metastases have been described in literature. We report a literature review and a case of MEH with a metastatic occurrence 4 years after surgical excision. PMID:27194877

    It is widely accepted that neurobiological abnormalities underlie the symptoms of psychiatric disorders such as schizophrenia and unipolar or bipolar affective disorders. New molecular methods, computer-assisted quantification techniques and neurobiological investigation methods that can be applied to the human brain are all used in post-mortem investigations of psychiatric disorders. The following article describes modern quantitative methods and recent post-mortem findings in schizophrenia and affective disorders. Using our brain bank as an example, necessary considerations of modern brain banking are addressed such as ethical considerations, clinical work-up, preparation techniques and the organization of a brain bank, the value of modern brain banking for investigations of psychiatric disorders is summarized.

    Cancer stem cells (CSCs) represent a subpopulation of tumour cells endowed with self-renewal and multi-lineage differentiation capacity but also with an innate resistance to cytotoxic agents, a feature likely to pose major clinical challenges towards the complete eradication of minimal residual disease in cancer patients. Operationally, CSCs are defined by their tumour-propagating ability when serially transplanted into immune-compromised mice and by their capacity to fully recapitulate the original heterogeneity of cell types observed in the primary lesions they are derived from. CSCs were first identified in haematopoietic malignancies and later in a broad spectrum of solid tumours including those of the breast, colon and brain. Notably, several CSC characteristics are relevant to metastasis, such as motility, invasiveness and, as mentioned above, resistance to DNA damage-induced apoptosis. Here, we have reviewed the current literature on the relation between CSCs and metastasis formation. Preliminary studies on cancer cell lines and patient-derived material suggest a rate-limiting role for stem-like cells in the processes of tumour cell dissemination and metastasis formation. However, additional studies are needed to deliver formal proof of their identity as the cell of origin of recurrences at distant organ sites. Nevertheless, several studies have already provided pre-clinical evidence of the efficacy of novel therapies directed against disseminated CSCs.

    Ever since Stephen Paget's 1889 hypothesis, metastatic organotropism has remained one of cancer's greatest mysteries. Here we demonstrate that exosomes from mouse and human lung-, liver- and brain-tropic tumour cells fuse preferentially with resident cells at their predicted destination, namely lung fibroblasts and epithelial cells, liver Kupffer cells and brain endothelial cells. We show that tumour-derived exosomes uptaken by organ-specific cells prepare the pre-metastatic niche. Treatment with exosomes from lung-tropic models redirected the metastasis of bone-tropic tumour cells. Exosome proteomics revealed distinct integrin expression patterns, in which the exosomal integrins α6β4 and α6β1 were associated with lung metastasis, while exosomal integrin αvβ5 was linked to liver metastasis. Targeting the integrins α6β4 and αvβ5 decreased exosome uptake, as well as lung and liver metastasis, respectively. We demonstrate that exosome integrin uptake by resident cells activates Src phosphorylation and pro-inflammatory S100 gene expression. Finally, our clinical data indicate that exosomal integrins could be used to predict organ-specific metastasis.

    Metastases to the oral cavity are rare. However, in 25% of cases, oral symptoms will be the first sign of metastatic disease. The incidence of jaws metastases is twice as high as the incidence of metastases to the soft tissues of the oral cavity. In some cases, jaws metastases can mimic dental or periodontal pain. We report a case of a 67 year old female who was referred to our clinic because of severe pain on her left posterior mandible which was not relieved by endodontic treatment of the first and second molar. She was diagnosed with breast cancer in 2005 and had been treated with surgery, chemotherapy and radiotherapy. Seven years later, lung metastases were found and she was treated with chemotherapy. Later on, brain metastases developed which had been treated with radiotherapy. On presentation, she complained of pain on the posterior left mandible which was accompanied by a burning sensation of the lower left lip and chin. CT scan revealed a soft tissue mass perforating the lingual and buccal plates of the posterior left mandible, which was compatible with a diagnosis of metastasis. Radiotherapy rapidly relieved the pain. Unfortunately, the patient passed away one month later. Dentists should be able to recognize the signs and symptoms associated with metastases to the jaws and should include it in the differential diagnosis, especially in patients with oncologic background.

    Dendritic cell-specific intercellular adhesion molecule-grabbing nonintegrin-related protein (DC-SIGNR) is a type II transmembrane protein which has been reported to bind a variety of pathogens as well as participate in immunoregulation. But the association between the level of DC-SIGNR and lung cancer is unknown. To investigate the clinical diagnostic significance of DC-SIGNR in lung cancer, we investigated serum DC-SIGNR levels in 173 lung cancer patients and 134 healthy individuals using enzyme-linked immunosorbent assay (ELISA). Results showed that serum DC-SIGNR levels in lung cancer patients were lower than that in healthy controls (P = 0.0003). A cut-off value of 3.8998 ng/L for DC-SIGNR predicted the presence of lung cancer with 78.03% sensitivity and 49.25% specificity (area under the curve = 0.6212, P = 0.0003). Strikingly, serum DC-SIGNR levels were significantly higher in lung cancer patients with brain metastasis compared to those without metastasis (P = 0.0283). Moreover, the serum concentrations of DC-SIGNR in lung cancer patients also correlated significantly with serum natural killer cells percentage (P = 0.0017). In addition, immunohistochemistry assay demonstrated that the expression of DC-SIGNR in lung tissues of 31 lung cancer patients and 13 tuberculosis patients was significantly lower than that in 18 normal lung tissues (P = 0.0418, 0.0289), and there is no significant difference between tuberculosis tissues and lung cancer tissues (P = 0.2696). These results suggest that DC-SIGNR maybe a promising biological molecule that has the potential for clinical research of lung cancer, whereas its underlying roles are needed to be investigated in further studies.

    The MA11 human breast-cancer cell line was established with cells isolated from a bone-marrow sample using immunomagnetic beads conjugated to the anti-MUC1 antibody BM-2. The cell line showed a selective preference for metastasising to the brain in athymic nude mice. Following injection of MA11 cells into the left ventricle of the heart, brain metastases developed in 87% (20/23) animals, with a mean latency until development of neurological symptoms of 65 days. Necropsy and histological examination revealed tumour nodules of varying sizes throughout the brain, invading both grey and white matter of both hemispheres, and with extensive involvement of the cerebellum. MRI spin-echo images indicated brain lesions in some animals that were subsequently confirmed by histology. Three mice showed small tumour nodules (1-2 mm) in the lung, and 2 had solitary lesions (< 1 mm) within the spinal cord. Metastases were not detected in bone, liver, adrenal gland, kidney, spleen or heart. The human MUC1 mucin, as determined by a europium-based immunoradiometric assay, was detected in the serum of 9/11 animals that showed histological evidence of brain metastases. The mucin could not be found in mouse serum samples taken before day 46. The concentration range of MUC1 observed was from <1 to >50 U/ml, and did not appear to correlate with the size or number of tumours as determined from histological sections. This new model provides an opportunity to study the mechanisms of clinically relevant organ-selective metastases and may be of use in evaluating novel treatment for brain metastases in breast cancer.

    Port-site metastases (PSMs) are well-known potential complications of laparoscopic surgery for gynaecologic malignancies. The present case study reports PSM following laparoscopic surgery for Stage IA Grade 1 endometrioid endometrial cancer (EEC). The recurrence developed within 7 months following primary surgery and required surgical excision followed by adjuvant chemo-radio therapy. After 9 months, the patient remains disease-free. PSMs are rare complications following laparoscopic surgery. Amongst the 23 cases of endometrial cancer PSMs reported so far, only 4 followed EEC Stage IA Grade 1–2. The present study reports a rare case of PSM after Stage IA Grade 1 EEC. The clinical and prognostic relevance of PSMs has not been identified so far; and it is not known whether PSMs represent a local recurrence or a systemic recurrence. Surgeons should be aware that even low-risk EEC may be followed by PSMs and should take steps to prevent these rare recurrences. PMID:27347138

    Sentinel lymph node detection (SLND) with radiocolloid has become widely used for evaluation of nodal metastasis in primary breast cancer. However, the procedure for recurrent breast cancer is not well established. Contralateral axillary node metastasis is uncommon. We report 2 cases of contralateral axillary node metastasis with recurrent breast cancer. In the first case, contralateral node metastasis was found by SLND. In the other case without SLND, contralateral node metastasis developed after resection of local recurrence. FDG-avid contralateral node was pathologically diagnosed as metastasis. The SLND might be useful in patients with local recurrence after conservative breast cancer surgery. PMID:24368539

    This systematic review aims to improve understanding of the burden of disease associated with brain metastases from non-small-cell lung cancer (NSCLC) in terms of survival, quality of life (QoL) and economic impact. PubMed/MEDLINE, Cochrane collaboration and EMBASE databases were searched for articles published in English from 2000 to 2014. Of 3288 abstracts retrieved, 3156 were eliminated without a full-text review. Of the 132 articles that received a full-text review, a final set of 93 articles was included in an initial literature analysis. In order to homogenize the patient populations evaluated, we included entries that were either entirely composed of NSCLC patients or that had >50% of NSCLC patients in the total study population. From the studies identified in this systematic review, median OS and PFS varied based on the type of treatment received, although whole-brain radiotherapy (WBRT) was associated with the shortest OS and PFS durations. Regimens incorporating targeted therapy in molecularly selected patients were associated with the longest OS and PFS durations. QoL findings varied among studies, generally WBRT resulted in stable or worsening QoL scores rather than improvements. Healthcare costs were increased following diagnosis of brain metastases regardless of treatment. The findings from this review highlight the need for more effective treatments of brain metastases from NSCLC that improve survival function, QoL and potentially decrease costs. PMID:27019457

From the studies identified in this systematic review, median OS and PFS varied based on the type of treatment received, although whole-brain radiotherapy (WBRT) was associated with the shortest OS and PFS durations. Regimens incorporating targeted therapy in molecularly selected patients were associated with the longest OS and PFS durations. QoL findings varied among studies, generally WBRT resulted in stable or worsening QoL scores rather than improvements. Healthcare costs were increased following diagnosis of brain metastases regardless of treatment. The findings from this review highlight the need for more effective treatments of brain metastases from NSCLC that improve survival function, QoL and potentially decrease costs.

    The present study reports the case of a 67-year-old female patient who was initially diagnosed with pulmonary aspergilloma. This diagnosis was based on a chest computed tomography (CT) scan showing a cavitary lesion of 3.5 cm in diameter, with fungus ball-like shadows inside, and an air crescent sign in the right upper lung. At 63 years old, the patient was treated for transitional cell cancer of the urothelium (non-invasive, pT1N0M0) by total cystectomy, ileal conduit diversion and urostomy. For 4 years post-operatively, the patient was healthy and had no clinical symptoms, and the air crescent sign was not identified by chest CT until the patient had reached 67 years of age. However, a final diagnosis of lung metastasis of transitional cell cancer of the urothelium was histopathologically identified subsequent to video-assisted thoracic surgery. Although it is rare that transitional cell cancer moves to the lung and makes a cavitary lesion, a differential diagnosis of cancer is necessary, even when examining infected patients with air crescent signs that are characteristic of aspergilloma. The physician must be mindful of metastatic pulmonary tumors that closely resemble aspergillomas, not only in infectious diseases, but also in oncological practice. Primary surgical removal should be considered. PMID:24959226

    A 68-year-old man was diagnosed with rectal cancer on colonoscopy and liver metastasis of rectal cancer on abdominal computed tomography(CT). He underwent resection of the primary lesion, and the final diagnosis was A, N1, H1, P0, M0, fStage IV. After resection of the primary lesion, he received chemotherapy with mFOLFOX6 plus cetuximab. After 6 courses of the treatment, CT revealed partial response of the liver metastasis. Then, he underwent resection of the liver metastasis. The pathological finding revealed that the resected specimen had no cancer cells. After resection of the liver metastasis, he received 6 courses of chemotherapy with the same regimen, and relapse-free survival continues until the time of this writing. PMID:27539045

    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

    A derangement of brain wound healing may cause some cases of Alzheimer's disease. Wound healing, a highly complex process, has four stages: hemostasis, inflammation, repair, and remodeling. Hemostasis and the initial phases of inflammation in brain tissue are typical of all vascularized tissue, such as skin. However, distinct differences arise in brain tissue during the later stages of inflammation, repair, and remodeling, and closely parallel the changes of Alzheimer's disease. Our hypothesis -- Alzheimer's disease is brain wound healing gone awry at least in some cases -- could be tested by measuring progression with biomarkers for the four stages of wound healing in humans or appropriate animal models. Autopsy studies might be done. Chronic traumatic encephalopathy might also result from the brain wound healing process. PMID:27585229

    Signet-ring cell carcinoma is a highly malignant adenocarcinoma consisting of cells characterized as cytoplasmic vacuoles filled with mucin. The most common primary location of this type of cancer is the stomach, but it may also be found in other organs such as prostate, testis, bladder, ovaries, or colon. To date, metastatic signet-ring cell carcinoma of unknown primary (CUP) site to the testis is an extremely rare entity in daily practice. Reviewing the literature, we have been able to detect only three cases of testicular metastases from CUP, two with histological diagnosis of a signet-ring cell carcinoma and one with an adenocarcinoma. In this short paper, we report a case of a 56-year-old man who presented to our Department with testicular mass and ascites. Following a standard diagnostic approach no primary tumor could be identified. CUP was the final clinical diagnosis, histologically characterized as poorly differentiated adenocarcinoma with signet-ring cells involving the peritoneum and the testicular structures.

    "Hyalinizing spindle cell tumor with giant rosettes" (HSCTGR) is a recently described tumor, which is regarded as an unusual variant of low-grade fibromyxoid sarcoma. Proof of a metastatic potential was lacking. The patient in the report was a 35-yr-old woman who showed multiple bilateral pulmonary nodules with massive pleural effusion in the right side. She had a history of a mass excision in the right thigh 11 yrs ago at another hospital, which was reported as a "leiomyoma". Two years before this presentation, the patient received a routine chest radiograph which demonstrated bilateral multiple pulmonary nodules. A lobectomy of the left upper lung was performed. The histological findings revealed a well-circumscribed nodule that was characterized by a spindle-shaped fibrous to hyalinized stroma with criss-crossing short fascicles and giant collagen rosettes surrounded by a rim of spindle-shaped cells. Electron microscopy confirmed the fibroblastic nature of the tumor. This case, in addition to at least two other cases reported in the literature, demonstrates that the HSCTGR is a malignant neoplasm with the capacity to metastasize after a long hiatus.

    Pilomatrix carcinoma is an extremely rare skin tumor derived from basaloid cells in the hair follicles; it often exhibits locally aggressive behavior with a tendency toward local recurrence. The average age of occurrence is 45 years, and there appears to be a male to female incidence ratio of 4:1. Although pilomatrix carcinomas are predominantly identified in the neck and scalp, there are studies in the literature reporting other tumor development sites, including the upper extremities, torso and popliteal fossa. If diagnosed at an early stage, this malignant tumor is generally treated with wide surgical resection. However, for the advanced-stage tumors, there are no standard treatment procedures known to produce good results. The current study presents the case of a 76-year-old male with pilomatrix carcinoma originating from the scalp with metastases to the lung. The patient had a rapid and complete clinical response following an oral combination chemotherapy regimen of cyclophosphamide and etoposide. PMID:24932268

    Papillary thyroid carcinoma (PTC) is typically an indolent disease characterized by slow growth and a favorable prognosis. In rare instances, this disease may metastasize to the pleura and manifest as a malignant pleural effusion. We report 3 female patients of Japanese/Okinawan ancestry with a history of PTC who presented with hydrothorax. Cytologic examination in conjunction with immunohistochemical staining enabled a definitive diagnosis of metastatic PTC. Molecular analysis of the mitogen activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K) pathways demonstrated the presence of the v-raf murine sarcoma viral oncogene homolog B (BRAF)V600E mutation in 2 of our 3 patients, with the absence of any other clinically significant mutations in all cases. Further investigation is necessary to elucidate the molecular and environmental mechanisms involved in this aggressive manifestation of PTC. PMID:25755913

    Penile cancer as primary disease is relatively rare in developed countries. The penis is a rare site of metastases in spite of its rich vascularization. Approximately 500 cases have been reported in the literature; almost 70% of primary lesions are of pelvic origin (from genitourinary or recto-sigmoid primary tumors). We describe a case of penile metastasis from lung cancer. The rarity of the event prompted us to also explore related reviews and discuss the incidence, physiopathology, diagnosis and therapy of penile secondary cancer. PMID:25992200

    Thymoma and thymic carcinoma are rare epithelial tumors, which originate from the thymus gland. According to the World Health Organization there are “organotypic” (types A, AB, B1, B2, and B3) and “non-organotypic” (thymic carcinomas) thymomas. Type B3 thymomas are aggressive tumors, which can metastasize. Due to the rarity of these lesions, only 7 cases of extradural metastasis are described in the literature. We report the first and unique case of a man with cervical intradural B3 thymoma metastasis. A 46-year-old man underwent thymoma surgical removal. The year after the procedure he was treated for a parietal pleura metastasis. In 2006 he underwent cervical-dorsal extradural metastasis removal and C5-Th1 stabilization. Seven years after he came to our observation complaining left cervicobrachialgia and a reduction of strength of the left arm. He underwent a cervical spine magnetic resonance imaging, which showed a new lesion at the C5-C7 level. The patient underwent a surgery for the intradural B3 thymoma metastasis. Neurological symptoms improved although the removal was subtotal. He went through postoperative radiation therapy with further mass reduction. Spinal metastases are extremely rare. To date, only 7 cases of spinal extradural metastasis have been described in the literature. This is the first case of spinal intradural metastasis. Early individuation of these tumors and surgical treatment improve neurological outcome in patients with spinal cord compression. A multimodal treatment including neoadjuvant chemotherapy, surgery and postoperative radiation therapy seems to improve survival in patients with metastatic thymoma. PMID:26601098

    Metastasis is the leading cause of breast cancer-associated deaths. Despite the significant improvement in current therapies in extending patient life, 30–40% of patients may eventually suffer from distant relapse and succumb to the disease. Consequently, a deeper understanding of the metastasis biology is key to developing better treatment strategies and achieving long-lasting therapeutic efficacies against breast cancer. This review covers recent breakthroughs in the discovery of various metastatic traits that contribute to the metastasis cascade of breast cancer, which may provide novel avenues for therapeutic targeting.

    Painful bone metastases are common in prostate cancer, with current treatments including non-steroidal analgesics and opiates, surgery, external beam radiotherapy and bone-targeting β-emitting radiopharmaceuticals. The α-emitting isotope 223Ra-dichloride (Ra-223) has been associated with improved overall survival and increased time to first skeletal-related events in patients with castration-resistant prostate cancer (CRPC) presenting with symptomatic bone metastases. The current study reports the case of a 70-year-old male patient, who was diagnosed with prostate cancer in 1999 upon presentation with increased prostate-specific antigen (PSA) levels and painful bone metastases in the context of CRPC. In November 2010, subsequent to undergoing hormonal blockage, the patient was treated with ketoconazole (200 mg/8 h) followed by 10 cycles of docetaxel (75 mg/m2 every 3 weeks). Following disease progression, the patient received 6 doses of Ra-223 (50 kBq/kg; 1 dose/4 weeks). During this treatment period, an improvement in the patient's symptoms, and levels of bone alkaline phosphatase (BAP) and PSA were noted. Furthermore, Ra-223 was well-tolerated without any relevant bone marrow toxicity. However, 2 months after the administration of the final dose of Ra-223, PSA and BAP levels increased again, and bone pain deteriorated. A bone scan showed stable disease in the previously observed metastatic lesions; however, new lesions simultaneously appeared in different locations, indicating progressive disease. PMID:27446432

    Metastatic tumors result from hematogenous spread through a tumor located at a distance. All these tumors represent about 1% of malignant tumors of the oral cavity (1). The most common location is the mandible (70%), more rarely maxillary (2). The most frequently encountered tumors are carcinomas or adenocarcinomas of mammary origin, brocho-lung, prostate, kidney or another. This study reports the case of a 46 year-old man, who presented for consultation with a low left laterofacial swelling, paresthesia lip and chin straight associated with pain at the lower edge of the mandible evolving for 2 months. The patient is known to take alcohol and tobacco for 20 years. The panoramic radiograph showed radiolucent image with blurred boundaries at the lower right premolar region. Dentascan revealed an irregular osteolytic lesion with rupture of the table lingual. After surgical exploration, the pathological examination is for a well-differentiated and invasive adenocarcinoma of the mandible. Extension work-up shows the presence of a tumor right lung, a lytic lesion at the 8th costal arch, the fourth dorsal vertebra and another location in fibula. The surgical exploration of pulmonary was performed and confirmed the pulmonary primitive localization of adenocarcinoma. PMID:24979959

    The role of brain 18F-FDG PET in the diagnostic evaluation of encephalitis has been recently suggested, especially in limbic encephalitis, but descriptions are mainly limited to small case reports. However, the evaluation of cerebral metabolism by 18F-FDG PET has never been described for varicella-zoster virus encephalitis. We report the first case of varicella-zoster virus encephalitis in which 18F-FDG PET revealed brain metabolic abnormalities. Brain metabolic PET imaging was analyzed by comparing the patient's brain 18F-FDG PET scans to that of 12 healthy subjects. Compared with healthy subjects, significant hypometabolism and hypermetabolism were found and evolved over time with treatment.

    Background: Previous reports have proposed an association between traumatic brain injury (TBI) and subsequent glioblastoma (GBM) formation. Methods: We used literature searches and radiographic evidence from two patients to assess the possibility of a link between TBI and GBM. Results: Epidemiological studies are equivocal on a possible link between brain trauma and increased risk of malignant glioma formation. We present two case reports of patients with GBM arising at the site of prior brain injury. Conclusion: The hypothesis that TBI may predispose to gliomagenesis is disputed by several large-scale epidemiological studies, but supported by some. Radiographic evidence from two cases presented here suggest that GBM formed at the site of brain injury. We propose a putative pathogenesis model that connects post-traumatic inflammation, stem and progenitor cell transformation, and gliomagenesis. PMID:27625888

She was treated with prothionamide, moxifloxacin, cycloserine, and kanamycin. However, her headache and brain lesion worsened. After the brain biopsy, the patient was confirmed with intracranial tuberculoma. Linezolid was added to intensify the treatment regimen, and steroid was added for the possibility of paradoxical response. Kanamycin was discontinued 6 months after initiation of the treatment; she was treated for 18 months with susceptible drugs and completely recovered. To our knowledge, this case is the first multidrug-resistant tuberculosis that disseminated to the brain in Korea. PMID:27104015

    This case study describes the history of an older person, born in 1942 preterminally, who suffered from a brain injury in 2005. Problems in rehabilitation elicited the search for a new meaning in life. In analysing and interpreting the brain injury, preterm birth played a crucial role. The theme of lifelong compensation of deficits, caused by preterm birth, gained new importance. The consequences of brain injury left unsuccessful his former modes of compensation. He was confronted with finding new strategies in order to counterbalance the growing decompensation. This report is based on and was developed through respect for the principles of user involvement in research.

    The current study describes the case of a woman with symptomatic epilepsy due to brain cysticercosis acquired during childhood. During her adolescence, she developed seizures characterized by metamorphopsia, hallucinations of autobiographic memory and, finally, asomatognosia. Magnetic brain imaging showed a calcified lesion in the right occipitotemporal cortex, and positron emission tomography imaging confirmed the presence of interictal hypometabolism in two regions: the right parietal cortex and the right lateral and posterior temporal cortex. We discuss the link between these brain areas and the symptoms described under the concepts of epileptogenic lesion, epileptogenic zone, functional deficit zone, and symptomatogenic zone.

    It is well known that progranulin protein is involved in wound repair, inflammation, and tumor formation. The wedding between progranulin and brain was celebrated in 2006 with the involvement of progranulin gene (GRN) in Frontotemporal lobar degeneration (FTLD), the most common form of early-onset dementia: up to date, 75 mutations have been detected in FTLD patients as well as in patients with widely variable clinical phenotypes. All pathogenic GRN mutations identified thus far cause the disease through a uniform mechanism, i.e. loss of functional progranulin or haploinsufficiency. Studies on GRN knockout mice suggest that progranulin-related neurodegenerative diseases may result from lifetime depletion of neurotrophic support together with cumulative damage in association with dysregulated inflammation, thus highlighting possible new molecular targets for GRN-related FTLD treatment. Recently, the dosage of plasma progranulin has been proposed as a useful tool for a quick and inexpensive large-scale screening of affected and unaffected carriers of GRN mutations. Before it is systematically translated into clinical practice and, more importantly, included into diagnostic criteria for dementias, further standardization of plasma progranulin test and harmonization of its use are required. Once a specific treatment becomes available for these pathologies, this test - being applicable on large scale - will represent an important step towards personalized healthcare.

    Melanoma has been found to metastasise to the spleen, usually in cases of disseminated disease. Solitary splenic metastasis from cutaneous melanoma is very rare. Herein we report the case of a 43-year-old man who developed solitary splenic metastasis from cutaneous melanoma. The patient was operated for T4b N1a Mo superficial spreading melanoma of the anterior thoracic wall. He subsequently underwent left axillary lymph node dissection due to a positive sentinel lymph node. The 33 retrieved lymph nodes were negative for metastasis. The patient received adjuvant therapy with high-dose interferon α-2b. After 27 months and during the follow-up visit an increasing lactate dehydrogenase serum level was observed. Furthermore, CT of the whole body revealed a solitary hypodense tumour of the spleen 9 cm×6 cm. Curative splenectomy was performed and the histopathological report confirmed metastatic melanoma to the spleen. PMID:23104633

    The relationships between brain tumor mortality and occupation and socioeconomic status (SES) were evaluated in a death certificate-based case-control study. The cases consisted of 904 white men aged 20 years and older who died of a brain tumor in Washington state between 1969 and 1978. For each case a white male control of the same age was chosen. A consistent pattern of increasing risk with increasing SES was seen for all brain tumors as well as for gliomas and astrocytomas. After adjustment for SES, stationary engineers were found to be at excess risk across all histologies based on six cases vs no controls with lower 95% confidence intervals of 2.3 for all brain tumors, 2.8 for gliomas (based on three cases), and 2.1 for astrocytic tumors (based on two cases). Excesses of astrocytic tumors also were observed for petroleum refinery workers (OR = 8.8, CI = 2.2-35.2), forestry workers (OR = 8.5, CI = 1.1-63.4), and cleaning service workers (OR = 2.7, CI = 1.1-6.7).

    Over the past several years, the study of self-related cognition has garnered increasing interest amongst psychologists and cognitive neuroscientists. Concomitantly, lesion and neuroimaging studies have demonstrated the importance of intact cortico-cortical and cortico-subcortical connections for supporting high-level cognitive functions. Commissurotomy or "split-brain" patients provide unique insights into the role of the cerebral commissures in maintaining an individual's sense of self, as well as into the unique self-representation capabilities of each cerebral hemisphere. Here we review empirical work examining the integrity of self-related processes in patients with various disconnection syndromes, focusing on studies of self-recognition, ownership, and agency. Taken together, this body of work suggests that an intact corpus callosum enabling interhemispheric transfer is necessary for some, but not all types of self-representations.

    We conducted an exploratory study to investigate which exposures (including poultry oncogenic viruses) are associated with brain cancer in poultry workers. A total of 46,819 workers in poultry and nonpoultry plants from the same union were initially followed for mortality. Brain cancer was observed to be in excess among poultry workers. Here we report on a pilot case-cohort study with cases consisting of 26 (55%) of the 47 brain cancer deaths recorded in the cohort, and controls consisting of a random sample of the cohort (n = 124). Exposure information was obtained from telephone interviews, and brain cancer mortality risk estimated by odds ratios. Increased risk of brain cancer was associated with killing chickens, odds ratio (OR) = 5.8 (95% confidence interval, 1.2-28.3); working in a shell-fish farm, OR = 13.0 (95% CI, 1.9-84.2); and eating uncooked fish, OR = 8.2 (95% CI, 1.8-37.0). Decreased risks were observed for chicken pox illness, OR = 0.2 (95% CI, 0.1-0.6), and measles vaccination, OR = 0.2 (95% CI, 0.1-0.6). Killing chickens, an activity associated with the highest occupational exposure to poultry oncogenic viruses, was associated with brain cancer mortality, as were occupational and dietary shellfish exposures. These findings are novel.

    The primary brain tumors associated with cerebral aneurysms are rare in neurosurgical practice. The present article constitutes an evaluation of the management of coexistent primary brain tumor and cerebral aneurysm. A retrospective study of three cases of primary brain tumor with cerebral aneurysm was performed. We evaluated the complications and clinic outcomes by assessing the clinical and imaging findings. Case 1 presented with a subarachnoid hemorrhage from an aneurysm of the anterior communicating artery, with an incidental left frontal oligodendroglioma. Case 2 presented with chronic headache due to left frontal convexity meningioma, with proximal internal carotid artery aneurysm which was found incidentally during preoperative magnetic resonance angiography. Case 3 was admitted to our hospital complaining of headache, memory disturbance, and weakness in her left lower extremity. Magnetic resonance imaging revealed right frontal lymphoma and an unruptured aneurysm at the left middle cerebral artery. Preoperative magnetic resonance imaging revealed right frontal lymphoma and unruptured left middle cerebral artery. The frequency of primary brain tumor and cerebral aneurysm coexistence is increasing due to improvements in high-resolution imaging. In these complicated cases, the management will differ according to each pathology present, and this is an important problem for a neurosurgeon.

    Lung cancer has been well documented to spread to bone and the axial skeleton after metastasis to adjacent organs. Bony metastasis is not, however, the typical presenting manifestation. The differential diagnosis for a tissue mass on the skull should warrant a workup for metastatic disease. Bony metastasis plays an important role in treatment and disease management. We report an exceptionally rare case of stage IV lung adenocarcinoma that presented with a solitary skull metastasis and a significant soft-tissue component. The lesion was treated by excision via craniotomy and subsequent medical management of the adenocarcinoma. This case illustrates a very rare presentation of lung adenocarcinoma and also represents what the authors believe to be the first report of a solitary skull mass originating from a lung primary. We also present a review of the literature surrounding bony metastasis to the skull and implications for patient care. PMID:27340229

    Chordomas are rare, low grade, malignant tumours derived from the ectopic remnants of the notochord that line the axial skeleton. They are characterised by their slow growth, long disease course and propensity for local relapse. Furthermore, up to 40% of non-cranial chordomas metastasise. We describe the first reported case of a hand metastasis arising from a conventional sacral chordoma after carbon ion radiotherapy. The common occurrence of distant metastasis with chordomas makes it important to perform a systemic examination, in part because their resection might improve patient prognosis. PMID:25350167

    Lymph node metastasis of nasopharyngeal carcinoma follows an orderly pattern, and diagnosis of nasopharyngeal carcinoma is often made by lymph node biopsy. In the present study, following neck palpation, ultrasonography and cervical computer tomography, a 52-year-old female patient with thyroid adenoma and enlarged cervical lymph nodes was misdiagnosed as thyroid carcinoma without undergoing preoperative biopsy, followed by unnecessary total thyroidectomy. Systematic CT scan and nasal endoscopic biopsy confirmed the correct diagnosis of primary NPC concurrent with thyroid adenoma. The patient received palliative radiotherapy and L-thyroxine substitution therapy, and was followed up closely via internet-based approaches with life-style intervention, medication consultation and psychological support for improvement of life quality after radiotherapy. In conclusion, primary malignancies with thyroid metastasis must be considered in the differential diagnosis of thyroid tumors with enlarged cervical lymph nodes. PMID:27347179

    We investigated the contents of the insulin receptor-beta subunit (IRβ) and [Tyr1162/1163]-phosphorylated IRβ as surrogate indices of total IR content and IR activation in postmortem hippocampal formation brain specimens from nondiabetic sporadic Alzheimer's disease (AD) cases. We found no significant changes in the brain contents of total IRβ or [Tyr1162/1163]-phosphorylated IRβ, suggesting normal IR content and activation in the brains of nondiabetic sporadic AD cases. Moreover, total IRβ and [Tyr1162/1163]-phosphorylated IRβ levels in the hippocampal formation are not correlated with the severity of amyloid or tau-neuropathology. Exploring the regulation of glycogen synthase kinase 3 (GSK3) α/β, key IR-signaling components, we observed significantly lower levels of total GSK3 α/β in brain specimens from nondiabetic AD cases, suggesting that impaired IR signaling mechanisms might contribute to the onset and/or progression of AD dementia. Outcomes from our study support the development of insulin-sensitizing therapeutic strategies to stimulate downstream IR signaling in nondiabetic AD cases. PMID:22666619

    A 58-year-old woman was diagnosed with a sigmoid colon cancer and synchronous liver metastasis. Because an obstruction of the sigmoid colon was identified, the patient underwent sigmoidectomy. Computed tomography(CT)findings suggested possible vena cava and hepatic vein invasion. Therefore, the decision was made to offer systemic chemotherapy. The patient underwent 6 courses of chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6). After 4 courses of chemotherapy, CT scans showed a significant reduction of the liver metastasis (reduction rate of 5 0%; a partial response) and demonstrated improved exclusion of the inferior vena cava and hepatic vein. After 6 courses of chemotherapy, we performed right trisegmentectomy of the liver and resection of the inferior vena cava and diaphragm. Postoperative pathological findings revealed negative margins, and no invasion of the inferior vena cava. The pathological response grade of the tumor after chemotherapy was determined to be Grade 2. Adjuvant chemotherapy was not performed because of the patient 's poor performance status. The patient was alive with no recurrence 8 years after resection of the liver metastasis. PMID:26805305

    Background The relationship between functional recovery after brain injury and concomitant neuroplastic changes is emphasized in recent research. In the present study we aimed to delineate brain regions essential for language performance in aphasia using functional magnetic resonance imaging and acquisition in a temporal sparse sampling procedure, which allows monitoring of overt verbal responses during scanning. Case presentation An 80-year old patient with chronic aphasia (2 years post-onset) was investigated before and after intensive language training using an overt picture naming task. Differential brain activation in the right inferior frontal gyrus for correct word retrieval and errors was found. Improved language performance following therapy was mirrored by increased fronto-thalamic activation while stability in more general measures of attention/concentration and working memory was assured. Three healthy age-matched control subjects did not show behavioral changes or increased activation when tested repeatedly within the same 2-week time interval. Conclusion The results bear significance in that the changes in brain activation reported can unequivocally be attributed to the short-term training program and a language domain-specific plasticity process. Moreover, it further challenges the claim of a limited recovery potential in chronic aphasia, even at very old age. Delineation of brain regions essential for performance on a single case basis might have major implications for treatment using transcranial magnetic stimulation. PMID:16916464

    Gliomas are the most common primary brain tumors and yet almost incurable due mainly to their great invasion capability. This represents a challenge to present clinical oncology. Here, we introduce a mathematical model aiming to improve tumor spreading capability definition. The model consists in a time dependent reaction-diffusion equation in a three-dimensional spatial domain that distinguishes between different brain topological structures. The model uses a series of digitized images from brain slices covering the whole human brain. The Talairach atlas included in the model describes brain structures at different levels. Also, the inclusion of the Brodmann areas allows prediction of the brain functions affected during tumor evolution and the estimation of correlated symptoms. The model is solved numerically using patient-specific parametrization and finite differences. Simulations consider an initial state with cellular proliferation alone (benign tumor), and an advanced state when infiltration starts (malign tumor). Survival time is estimated on the basis of tumor size and location. The model is used to predict tumor evolution in two clinical cases. In the first case, predictions show that real infiltrative areas are underestimated by current diagnostic imaging. In the second case, tumor spreading predictions were shown to be more accurate than those derived from previous models in the literature. Our results suggest that the inclusion of differential migration in glioma growth models constitutes another step towards a better prediction of tumor infiltration at the moment of surgical or radiosurgical target definition. Also, the addition of physiological/psychological considerations to classical anatomical models will provide a better and integral understanding of the patient disease at the moment of deciding therapeutic options, taking into account not only survival but also life quality.

    Background: To demonstrate how adaptive hypofractionated radiosurgery by gamma knife (GK) can be successfully utilized to treat a large brainstem metastasis - a novel approach to a challenging clinical situation. Case Description: A 42-year-old woman, diagnosed with metastatic nonsmall cell lung cancer in July 2011, initially treated with chemotherapy and tyrosine kinase inhibitors, developed multiple brain metastases March 2013, with subsequent whole brain radiotherapy, after which a magnetic resonance imaging (MRI) showed a significant volume regression of all brain metastases. A follow-up MRI in October 2013 revealed a growing brainstem lesion of 26 mm. Linear accelerator-based radiotherapy and microsurgery were judged contraindicated, why the decision was made to treat the patient with three separate radiosurgical sessions during the course of 1 week, with an 18% tumor volume reduction demonstrated after the last treatment. Follow-up MRI 2.5 months after her radiosurgical treatment showed a tumor volume reduction of 67% compared to the 1st day of treatment. Later on, the patient developed a radiation-induced perilesional edema although without major clinical implications. An MRI at 12 months and 18-fluoro-deoxyglucose positron emission tomography of the brain at 13 months showed decreased edema with no signs of tumor recurrence. Despite disease progression during the last months of her life, the patient's condition remained overall acceptable. Conclusion: GK-based stereotactic adaptive hypofractionation proved to be effective to achieve tumor control while limiting local adverse reactions. This surgical modality should be considered when managing larger brain lesions in critical areas. PMID:26958430

    Metastatic spread of cancer cells from the primary tumors to distant vital organs, such as lung, liver, brain, and bone, is responsible for the majority of cancer-related deaths. Development of metastatic lesions is critically dependent on the interaction of tumor cells with the stromal microenvironment. As a multifunctional paracrine signaling factor that is abundantly produced by both tumor and stromal cells, TGFβ has been well established as an important mediator of tumor-stromal interaction during cancer metastasis. Imaging the in vivo dynamic of TGFβ signaling activity during cancer metastasis is critical for understanding the pathogenesis of the disease, and for the development of effective anti-metastasis treatments. In this chapter, I describe several xenograft methods to introduce human breast cancer cells into nude mice in order to generate spontaneous and experimental metastases, as well as the luciferase-based bioluminescence imaging method for quantitative imaging analysis of TGFβ signaling in tumor cells during metastasis.

    Vaginal cancer is a rare malignancy accounting for 1-2% of all pelvic neoplasms. Dissemination usually occurs through local invasion and rarely metastasises to distal locations. Metastasis of vaginal cancer to the breast is extremely infrequent and unique. A 66-year-old Asian woman presented with vaginal bleeding and was found to have a vaginal mass and a left breast mass. Pathological assessment of the biopsies revealed identical squamous cell characteristics of both masses. We describe a very rare and novel case of a distally located vaginal carcinoma with metastasis to the breast Federation of Gynecology and Obstetrics (FIGO) stage IV (FIGO IVB). Robot-assisted extrafascial total hysterectomy with local vaginal mass excision and partial mastectomy of the left breast were performed. After surgery, the patient underwent adjuvant chemotherapy followed by breast and pelvic radiotherapy, with maintained complete remission after 3 years of follow-up. This combination of findings and treatment is very distinct with a unique and favourable response.

    Objective Hypotonia is a common clinical entity well recognized in pediatric age group, which demands experienced clinical assessment and an extensive array of investigations to establish the underlying disease process. Neuroimaging comes as great help in diagnosing the disease process in rare cases of central hypotonia due to structural malformations of brain and metabolic disorders and should always be included as an important investigation in the assessment of a floppy child. In this article, we discuss the MRI features of eight cases of central and two cases of combined hypotonia and the importance of neuroimaging in understanding the underlying disease in a hypotonic child.

    Metastasis to the uterine corpus is uncommon and secondary colorectal tumours of the endometrium are rare. We describe a uterine tumour with components of both primary endometrial and metastatic colorectal carcinomata. In this case, a 72-year-old obese woman presented with a 2-week history of postmenopausal bleeding per vaginum and weight loss. She had an abdominoperineal resection 3 years previously for a Dukes stage B rectal carcinoma. A transvaginal ultrasonography showed a thickened endometrium. Histology immunophenotyping showed a CK7+, CK20+, CA125− and CEA+ colorectal metastasis (a profile consistent with her previous cancer) associated with a primary CK7+, CK20−, CA125+ and CEA− endometroid endometrial adenocarcinoma. We conclude this represents endometrial metastasis of colorectal carcinoma with coincident primary endometrial adenocarcinoma. We speculate as to whether the endometrial carcinoma arose de novo or was induced by the colorectal metastasis, or whether the primary endometrial tumour provided a fertile site for the colorectal metastasis.

    The bone is a common site for metastasis in hepatocellular carcinoma (HCC). However, bone marrow metastasis from HCC is rarely reported, and its frequency is unclear. Here we report a rare case of bone marrow metastasis that presented as bicytopenia originating from HCC without bone metastasis. A 58-year-old man was admitted for investigation of a liver mass with extensive lymph node enlargement that was detected when examining his general weakness and weight loss. Laboratory findings revealed anemia, thrombocytopenia, mild elevated liver enzymes, normal prothrombin time percentage and high levels of tumor markers (α-fetoprotein and des-γ-carboxyprothrombin). Abdominal computed tomography showed multiple enhanced masses in the liver and multiple enlarged lymph nodes in the abdomen. A bone marrow biopsy revealed only a few normal hematopoietic cells and abundant tumor cells. Despite its rarity, bone marrow metastasis should always be suspected in HCC patients even if accompanied by cirrhosis. PMID:27184470

    Brain abscess caused by Cladophialophora bantiana is a rare disease associated with high mortality due to delay in diagnosis and absence of standardized therapy. We reviewed 124 culture proven C. bantiana brain abscess cases; 103 cases published in English literature during 1952 through 2014 and 21 unpublished cases from our reference center. The majority (57.3%) of the patients was from Asian countries especially from India (62/124, 50%). The diagnosis of the cases was delayed with mean duration 115 days after developing symptoms. The disease was nearly equally distributed in immunocompetent and immunosuppressed hosts but associated with significantly higher mortality (77.1%) in later group. Complete excision of brain lesion in immunocompetent host led to significantly better survival (43.7%). Though all commercially available antifungal drugs have been used in these patients, amphotericin B deoxycholate or lipid preparations were most commonly (62.83%) prescribed agent. None of the drugs used was found to be independently associated with improved outcome. In vitro antifungal susceptibility testing of 13 isolates of our center, demonstrated good activity to voriconazole, posaconazole, and itraconazole, but these triazoles were prescribed in only 29.2% patients. Increased awareness with early suspicion of the disease, and aggressive medical and surgical approach in treating these patients may improve the outcome. PMID:26483430

    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.

    Two hundred cases of verified brain tumors occurring in patients under 15 years of age were studied in relation to possible etiologic, genetic, and environmental risk factors. They were compared with 100 age-matched patients harboring solid neoplasms outside the nervous system, as well as with 100 normal children. In our study, first-degree relatives of a brain tumor child did not show a higher incidence of either tumors or of epilepsy and strokes as compared with controls. First-born children (46%) with higher birth weights showed a greater tendency to present brain tumors. Dystocia (18.5%), previous miscarriages (18%), and dietary restrictions during pregnancy (3%) were also noted in this study and compared with data in the literature. No evidence of a role of maternal chickenpox and toxoplasmosis could be found. The pharmacological risk also seemed to be minimal. The mother's hormonal profile is deduced from the age at menarche and delivery, as well as from a tendency to miscarriages and complicated pregnancies. With regard to the immunologic aspect, it is worth noting that 15% of the mothers complained of allergies. Live polio vaccine and zoonosis might suggest a possible role of virus-related factors in the oncogenesis of brain tumors in children. Radiation-related risk is possibly present in less than 5% of cases. Parental occupation is not relevant in this series.

    2016-01-01

    The two biological mechanisms that determine types of malignancy are infiltration and metastasis, for which tumour microenvironment plays a key role in developing and establishing the morphology, growth and invasiveness of a malignancy. The microenvironment is formed by complex tissue containing the extracellular matrix, tumour and non-tumour cells, a signalling network of cytokines, chemokines, growth factors, and proteases that control autocrine and paracrine communication among individual cells, facilitating tumour progression. During the development of the primary tumour, the tumour stroma and continuous genetic changes within the cells makes it possible for them to migrate, having to count on a pre-metastatic niche receptor that allows the tumour’s survival and distant growth. These niches are induced by factors produced by the primary tumour; if it is eradicated, the active niches become responsible for activating the latent disseminated cells. Due to the importance of these mechanisms, the strategies that develop tumour cells during tumour progression and the way in which the microenvironment influences the formation of metastasis are reviewed. It also suggests that the metastatic niche can be an ideal target for new treatments that make controlling metastasis possible. PMID:26913068

    The aim of the present study was to investigate the expression of thymidylate synthase (TYMS) in the primary foci and metastatic lymph nodes of low-grade glioma, and to analyze the function of TYMS in the lymph node metastases from low-grade glioma. The study included 93 cases of surgically resected and pathologically confirmed low-grade glioma, form patients treated at Huaihe Hospital of Henan University (Kaifeng, China). The following clinical data was obtained from each patient: Gender, age, subjective symptoms (dizziness, headache, a feeling of pressure in the head, etc.), site of disease, tumor type, pathological stage, degree of differentiation and lymph node involvement. The surgically resected gliomas and dissected cervical lymph nodes were immunohistochemically stained, and DNA was extracted from the tumor and lymph node tissues samples for polymerase chain reaction sequencing and amplification. The expression of TYMS in the primary foci and metastatic lymph nodes of low-grade glioma was examined. Additionally, the association between pathological features and the postoperative survival rate of the patients was analyzed. The primary lesions of all 93 cases exhibited positive TYMS expression and 43/157 (27.39%) lymph nodes exhibited positive TYMS expression. Factors that significantly influenced the postoperative survival rate of the patients, included the metastasis of the cervical lymph nodes (P<0.01), the number of dissected cervical lymph nodes (P<0.01) and the degree of differentiation (P<0.05). The metastasis of the cervical lymph nodes was the only independent risk factor affecting postoperative disease-free survival. The risk of recurrence in patients with metastasis of the cervical lymph nodes was 6.3-fold higher than in those without metastasis (P<0.01). Thus, the results of the present study provide a theoretical basis for accurately predicting the prognosis of patients with low-grade malignant brain glioma, reducing the conjecture involved in

    Background While extensive research has explored the impact of environmental factors on the etiology of specific cancers, the influence of exposures such as smoking on risk of site-specific metastasis is unknown. We investigated the association of cigarette smoking with lung metastasis in esophageal cancer. Methods We performed a case-control study of esophageal cancer patients from two centers, comparing cases with lung metastases to controls without lung metastases. Information was gathered from medical records on smoking history, imaging results, site(s) of metastasis, and other patient and tumor characteristics. We used logistic regression to assess association. Results We identified 354 esophageal cancer cases; smoking status was known in 289 (82%). Among patients with lung metastases, 73.6% (39/53) were ever smokers, versus 47.8% (144/301) of patients without lung metastases (p=0.001) (summary OR 2.52, 95%CI 1.17-5.45; stratified by histology). Smoking was associated with a nonsignificant increased adjusted odds of lung metastasis (OR 1.89, 95%CI 0.80-4.46). Upper esophageal subsite (OR 4.71, 95%CI 1.20-18.5) but not histology (squamous OR 0.65,95%CI 0.27-1.60) was associated with lung metastasis. Compared to the combined never/unknown smoking status group, smoking was associated with a significantly increased odds of lung metastasis (OR 2.35, 95%CI 1.11-4.97). There was no association between liver metastasis and smoking (OR 0.88, 95%CI 0.42-1.83) Conclusions Smoking is associated with increased odds of lung metastasis from esophageal cancer, and this relationship appears to be site-specific. Future studies are needed to determine whether smoking affects the tumor cell or the site of metastasis, and whether this changes the survival outcome. PMID:18843013

    Tumors of the central nervous system (CNS) are the most common solid tumors diagnosed in children. The most frequent symptoms of brain tumors in this age group are headaches and vomiting, regardless of the location of the lesions. These symptoms are non-specific, and in each case require differential diagnosis, especially if there is no gradual improvement in the patient's condition or progression. The most common signs of anorexia nervosa are chronic vomiting, weakness of the body, pain and in extreme cases cachexia. These symptoms are similar to the clinical image of CNS tumor. Teenager, described in our case report presented the following signs for several weeks prior to the diagnosis of a brain tumor: vomiting (especially after meals), non-specific headache and epigastric pain. No significant progression in the patient's condition oriented the diagnostic process towards anorexia nervosa. Although anorexia in this age group is much more common disease, compared to a brain tumor, it is vital to ruled out/ exclude organic disorders prior to diagnosis of psychogenic disorder. At the same time the waiting for the specialist consultations (ophthalmologist, neurologist) and test results (head CT, head NMR) should not prolong the patients referral to a specialist center.

    Leptomeningeal carcinomatosis (LMC) is rare metastatic form of gastric cancer. Most cases are diagnosed in the final stage after multiple distant metastasis. An 84-year-old woman was admitted with melena, headache and vomiting. Esophagogastroduodenoscopy showed an ulceroinfiltrating lesion at the stomach (Borrmann class III), and biopsy revealed a signet ring cell carcinoma. The abdominal-pelvic CT showed no evidence of metastasis. A sudden decrease of consciousness was noted, but the brain CT showed no active lesion while the brain MRI revealed enhancement of leptomeninges. A lumbar puncture was performed and the cerebrospinal fluid study revealed malignant neoplastic cells. With family consent, no further evaluation and treatment were administered and she died six weeks after the diagnosis of gastric cancer. We report an extremely rare case of a patient who initially presented with neurologic symptoms, and was diagnosed LMC from advanced gastric cancer without any evidence of metastasis in abdomen and pelvis.

    In patients with nonprostatic cancer, serum acid phosphatase activity is usually elevated when bone metastasis is present but not when bone metastasis is absent. The fraction responsible for serum enzyme elevation is a normal component of serum; it appears in gel electrophoresis as band 5; and is tartrate-resistant. It is suggested that the origin of acid phosphatase elevation is bone osteoclasts rather than cancer tissue, as is the case with prostatic carcinoma. Determination of serum acid phosphatase activity may be useful in the detection of bone metastasis.

    Background: Brain metastasis during pregnancy is a rare occurrence. In particular, there have only been three prior cases regarding breast cancer metastasis. We report a patient with breast cancer metastasis to the brain during pregnancy and review the literature. Case Description: The patient was a 35-year-old female with a history of breast cancer (estrogen receptor/progesterone receptor negative, human epidermal growth factor receptor 2/neu positive, status post-neoadjuvant docetaxel/carboplatin/trastuzumab/pertuzumab therapy, status post-bilateral mastectomies), and prior right frontal brain metastases (status post-resection, capecitabine/lapatinib/temozolomide therapy, and cyberknife treatment). Patient was found to be pregnant at 9 weeks’ gestation while on chemotherapy; the patient elected to continue with the pregnancy and chemotherapy was discontinued. At 14 weeks’ gestation, she returned with recurrent right frontal disease. She was taken for a craniotomy at 16 weeks’ gestation, which confirmed metastases. Six weeks later, patient returned with worsening headaches and fatigue, with more recurrent right frontal disease. She was started on decadron and chemotherapy (5-fluorouracil, adriamycin, and cyclophosphamide). Serial magnetic resonance imaging (MRI) demonstrated enlarging right frontal lesions. She underwent a craniotomy at 27 weeks’ gestation, and chemotherapy was discontinued promptly. Starting at 30 weeks’ gestation, she received whole brain radiation for 2 weeks. Subsequently, she delivered a baby girl via cesarean section at 32 weeks’ gestation. At 6 weeks follow-up, an MRI brain demonstrated no new intracranial disease, with stable postoperative findings. Conclusion: There is a lack of guidelines and clinical consensus on medical and surgical treatment for breast cancer metastases in pregnant patients. Treatment usually varies based upon underlying tumor burden, location, gestational age of the fetus, and patient's preference and

    Breast and lung cancers are the most common primary neoplasms to manifest with choroidal metastases. The incidence of choroidal metastases from metastatic lung cancer was reported to be 2–6.7%. We report a case of bilateral choroidal metastasis from non-small cell lung cancer. A 59-year-old Caucasian female patient, never a smoker, was diagnosed with stage IV lung adenocarcinoma metastatic to the pleura, bones, and the brain. Her initial scan of the chest showed innumerable soft tissue nodules and mediastinal adenopathy compatible with metastatic disease. Her initial brain MRI showed numerous small enhancing lesions consistent with extensive disease. Unfortunately, during her follow-up visits, she presented with bulge on her left eye. Simultaneously, her follow-up chest scan showed increase in the size of the lung nodules. She continued to have a reasonable performance status at that time, except for mild increase in her dyspnea. The choroidal metastases require a multidisciplinary care and should be among the differential patients with malignancy who present with ocular symptoms. PMID:25295203

    Brain metastases are common in patients with advanced breast cancer (BC), causing considerable morbidity and mortality. Eribulin is a microtubule dynamics inhibitor approved for treating certain patients with metastatic BC, previously treated with an anthracycline and a taxane. In the 301 phase 3 study in 1102 women with advanced BC, eribulin and capecitabine treatments did not differ for co-primary endpoints (overall survival [OS]: 15.9 vs 14.5 months, P = 0.056; progression-free survival [PFS]: 4.1 vs 4.2 months, P = 0.30). Here, we report outcomes for six patients (eribulin, n = 3; capecitabine, n = 3) who had received treatment for brain metastases from BC (BCBM) at baseline. All eribulin-treated patients experienced brain lesion shrinkage at some point during treatment, compared with one capecitabine-treated patient. Fewer patients in study 301 developed new BCBM with eribulin (13/544, 2.4%) compared with capecitabine (25/546, 4.6%). Eribulin does not cross the healthy blood-brain barrier (BBB), but could have the potential to do so after cranial radiation therapy. Capecitabine may cross the BBB and has demonstrated activity in BCBM. Data from these patients and previous cases suggest that further investigation of eribulin for BCBM may be warranted.

    Background Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases. Methods Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions per week and additional self-managed aerobic sessions. Outcome measures of strength, cardiovascular fitness, and several psychological indicators (depression, anxiety, and quality of life) were recorded at baseline, after 6 weeks and at the conclusion of the intervention. Results Exercise was well tolerated; both participants completed all 24 sessions and the home-based component with no adverse effects. Objective outcome measures displayed positive responses relating to reduced morbidity. Similar positive responses were found for psychological outcomes. Scores on the Hospital Anxiety and Depression Scale showed clinically meaningful improvements in depression and total distress. Conclusion These findings provide initial evidence that, despite the difficulties associated with brain cancer treatment and survivorship, exercise may be safe and beneficial and should be considered in the overall management of patients with brain cancer.

    A number of occupations and industries have been inconsistently associated with the risk of brain cancer. To further explore possible relationships, we conducted a population-based case-control study of brain glioma in the state of Iowa, involving 375 histologically confirmed incident cases and 2434 population-based controls. Among men, the industries and/or occupations that had a significantly increased risk for employment of more than 10 years included roofing, siding, and sheet metalworking; newspaper work; rubber and plastics products, particularly tires and inner tubes; miscellaneous manufacturing industries; wholesale trade of durable goods, grain, and field beans; cleaning and building service occupations; miscellaneous mechanics and repairers; and janitors and cleaners. Subjects who worked in plumbing, heating, and air conditioning; electrical services; gasoline service stations; and military occupations also experienced a significantly increased risk. Among women, significant excess risk was observed for occupations in agricultural services and farming, apparel and textile products, electrical and electronic equipment manufacturing, various retail sales, record-keeping, and restaurant service. Workers in industries with a potential for gasoline or motor exhaust exposures experienced a non-significant excess risk of brain glioma.

    2013-01-01

    The incidence of cancer is increasing worldwide, with the advent of a myriad of new treatment options, so is the overall survival of these patients. However, from an orthopaedic perspective, there comes the challenge of treating more patients with a variety of metastatic bone lesions. The consequences of such lesions can be significant to the patient, from pain and abnormal blood results, including hypercalcemia, to pathological fracture. Given the multiple options available, the treatment of bone metastasis should be based on a patient-by patient manner, as is the case with primary bone lesions. It is imperative, given the various lesion types and locations, treatment of bone metastasis should be performed in an individualised manner. We should consider the nature of the lesion, the effect of treatment on the patient and the overall outcome of our decisions. The dissemination of primary lesions to distant sites is a complex pathway involving numerous cytokines within the tumour itself and the surrounding microenvironment. To date, it is not fully understood and we still base a large section of our knowledge on Pagets historic “seed and soil” theory. As we gain further understanding of this pathway it will allow us develop more medical based treatments. The treatment of primary cancers has long been provided in a multi-disciplinary setting to achieve the best patient outcomes. This should also be true for the treatment of bone metastases. Orthopaedic surgeons should be involved in the multidisciplinary treatment of such patients given that there are a variety of both surgical fixation methods and non-operative methods at our disposal.

    Penetrating cranial injury by mechanisms other than gunshots are exceedingly rare, and so strategies and guidelines for the management of PBI are largely informed by data from higher-velocity penetrating injuries. Here, we present a case of penetrating brain injury by the low-velocity mechanism of a harpoon from an underwater fishing speargun in an attempted suicide by a 56-year-old Caucasian male. The case raised a number of interesting points in management of low-velocity penetrating brain injury (LVPBI), including benefit in delaying foreign body removal to allow for tamponade; the importance of history-taking in establishing the social/legal significance of the events surrounding the injury; the use of cerebral angiogram in all cases of PBI; advantages of using dual-energy CT to reduce artifact when available; and antibiotic prophylaxis in the context of idiosyncratic histories of usage of penetrating objects before coming in contact with the intracranial environment. We present here the management of the case in full along with an extended discussion and review of existing literature regarding key points in management of LVPBI vs. higher-velocity forms of intracranial injury.

    Invasive cerebral aspergillosis always developed in immunocompromised host. Early diagnosis may save life in this critical condition; however, it is difficult to reach. Herein, we presented an unusual case of invasive cerebral aspergillosis in a cirrhotic patient. A 47-year-old man presented with progressive deterioration of consciousness for three days. The patient had a history of alcoholic liver cirrhosis, Child-Pugh class C. Magnetic resonance imaging (MRI) of brain showed multi-focal parenchymal lesions, which was consistent with multiple brain abscesses. The diagnosis of invasive cerebral aspergillosis was made by molecular based laboratory methods including Aspergillus galactomannan antigen assay and oligonucleotide array. Despite treatment with the antifungal agent, Amphotericin B, the patient died at the ninth day of hospitalization. Our findings suggest that liver cirrhosis can be one of risk factors of invasive cerebral aspergillosis, and support the diagnosing usefulness of MRI, Aspergillus galactomannan antigen assay, and oligonucleotide array.

    In the surgery of meningiomas one of the most delicate problems is the separation of the tumor from the brain surface. The authors generally recommend microsurgery to preserve the brain surface anatomically and functionally. For this purpose we have developed a new surgical technique according to our concepts of tissue care. After excavating the tumor from inside the tumor brain surface was separated by repeated "water jets" into the tumor arachnoideal space. The "water jet" was produced by an ordinary bulb syringe. The front pressure of the jets was 300-1000 mm of water and the side pressure 100-300 mm of water. In the tumor-arachnoideal space the spreading water (phys. NaCl) separates the brain from the tumor with utmost care. We operated on 55 meningiomas of different types with the "water jet" technique. The immediate results were anatomically excellent. Intraoperative and postoperative acute and late edemas appeared only in a few cases. The functions of the nearby brain were generally preserved. The surgery was uneventful when the tumor surface was smooth and the tumor was spherical. When the tumor surface was uneven, one part of the tumor extended under the dura as a thin layer or the tumor was multilobulated with expanded vessels between the lobules, more microseparation was necessary. We compared the results of the "water jet" technique with the results of the "pre-water jet" series. The surgery with the "water jet" technique was much shorter and its results were better than those of microsurgery alone. PMID:3668608

    The mice with a disruption of Rank or Rankl exhibit normal mammary development during puberty, but their mammary epithelium fails to proliferate and form lobuloalveolar structures during pregnancy, resulting in the death of newborns. Hormone replacement therapy is associated with an increased risk of breast cancer. Importantly, specific deletion of RANK in mammary epithelium cells prevents both the onset and progression of medroxyprogesterone acetate (MPA) -driven mammary cancer and impairs self-renewal of breast cancer stem cells. Furthermore, RANK is highly expressed in several cancer cells. Functionally, it has been shown that RANKL can stimulate the directed migration of mammary epithelial cells as well as prostate cancer and melanoma cells toward a source of RANKL. In an in vivo metastasis model, OPG reduced the tumor burden in bones and ameliorated clinical paralysis, but did not affect the frequency of the spread of metastases into other tissues. These findings show that the RANK/RANKL system is crucial for mammary development, breast tumorigenesis and bone metastasis.

    We report a patient presenting with episodes of transient amnesia, some with features suggestive of transient global amnesia (TGA), and some more reminiscent of transient epileptic amnesia. Investigation with neuroimaging revealed an intrinsic lesion in the right amygdala, with features suggestive of low-grade neoplasia. We undertook a systematic review of the literature on TGA and brain tumour. Fewer than 20 cases were identified, some of which did not conform to the clinical diagnostic criteria for TGA. Hence, the concurrence of brain tumour and TGA is very rare and of doubtful aetiological relevance. In some brain tumour-associated cases, epilepsy may be masquerading as TGA. PMID:25802501

    A brain abscess is a life-threatening infection. There are few reports describing Prevotella bacteremia with middle cerebral artery (MCA) occlusion and brain abscess following dental extraction in the literature. We herein describe a 32-year-old healthy man who experienced headache after tooth extraction. He was not correctly diagnosed until he experienced a stroke and a blood culture revealed Prevotella denticola weeks later. This case and our detailed review of related cases highlight the importance of thorough medical history-taking and clinical evaluations. Brain abscess formation should be considered in previously healthy patients with fever, stroke, and a recent history of tooth extraction. PMID:25130130

    Poststroke central pain (PSCP) can be a debilitating medication-refractory disorder. We report a single case where right unilateral ventral capsule/ventral striatum (VC/VS) deep brain stimulation was used to treat PSCP and inadvertently induced a smile without euphoria. The patient was a 69 year-old woman who had a stroke with resultant dysesthesia and allodynia in her left hemibody and also a painful left hemibody dystonia. In her case, VC/VS stimulation induced a smile phenomenon, but without a euphoric sensation. This phenomenon was different from the typical smile responses we have observed in obsessive-compulsive disorder cases. This difference was considered to be possibly attributable to impairment in the emotional smile pathway.

    Over the years, there have been a number of well-publicized incidents involving persons who seemingly maneuver police officers into shooting them. Such cases, while relatively rare compared with most forms of violence, nevertheless pose difficult challenges to law enforcement agencies. Relatively little is known about persons who engage in suicide by cop incidents. To our knowledge, there has been no published indepth research on instigators of suicide by cop who survived. In this paper, we present a case study of an individual who engaged in and lived through three separate "attempted suicide by cop" incidents. After describing relevant history as well as events of the most recent incident, we compare the case with the extant literature on suicide by cop and analyze commonalities and differences. Finally, we examine the legal considerations involved, with particular attention devoted to the role the individual's traumatic brain injury played in applying the insanity defense.

    Metastasis of breast and prostate cancer as well as multiple myeloma to the bones represents a significant medical problem. We herein discuss the molecular basis of the creation of pre-metastatic niches, the process of bone metastasis and the phenomenon of tumor dormancy in the bone marrow as well as its regulation. We describe the identification and validation of genes mediating bone metastasis by use of pre-clinical models of bone metastasis. Additionally, we discuss the role of small integrin binding N-linked glycoproteins (SIBLINGS), the chemokine/chemokine receptor CXCL12/CXCR4 pathway and the role of micro RNAs (miRNAs) as mediators of bone metastasis. Finally, we summarize clinical achievements for the treatment of bone metastases.

    Ocular melanoma is the most common adult primary intraocular tumour. Although <1% of patients have metastatic disease at the time of initial diagnosis, most will develop metastasis at varying lengths of time. Metastasis surveillance is therefore critical in the follow-up of patients with ocular melanoma. Liver is the most common site of metastasis and prognosis is based on the treatment of liver metastasis. Hence, imaging of liver metastasis is vital. MRI is the most specific modality for imaging liver metastasis and is at least as sensitive as CT. Extrahepatic metastasis such as retroperitoneal nodules and bone metastases are also better evaluated on MRI. Gadolinium-based contrast agents are extremely helpful for detecting liver lesions. In particular, newer hepatobiliary contrast agents which offer an additional hepatobiliary phase of excretion help in the detection of even tiny liver metastases. Diffusion-weighted imaging is helpful when an i.v. contrast cannot be administered. Treated lesions are also better evaluated with MRI. CT is useful for evaluating lung nodules, large liver metastasis or in patients in whom MRI is medically contraindicated. The disadvantage lies in its inability to detect small liver metastasis and the radiation dose involved. The lesions treated with iodized oil as part of chemoembolization procedures can be followed on CT. Ultrasound can be used only for detecting hepatic metastases. However, it is heavily operator dependent, technically challenging and time consuming especially in patients who are large. Extrahepatic metastasis cannot be seen on ultrasound. Its utility is primarily for the biopsy of liver lesions. Positron emission tomography (PET)-CT can detect lung nodules and large liver lesions but is insensitive to small liver lesions. Moreover, the high radiation dose is a major disadvantage. PMID:27168029

    Introduction: Prostate carcinoma is the most frequently diagnosed carcinoma in the male population. The most typical places of the metastases are pelvic lymphatic glands, bones and lungs, and very rarely it metastasizes into a testis. The prognostic importance of testicular metastasis of prostate cancer is not yet well-known, due to a very few published cases. According to the known facts, it is certain that a metastasis of the prostate carcinoma into a testis is a sign of an advanced disease. Case report: This work presents a 48-year-old patient, to whom an adenocarcinoma of the prostate has been proven by the pathohistological finding of transrectal biopsy, performed due to the elevated level of prostate-specific antigen (PSA). Nine years after the initial diagnosis, due to a gradual rise of PSA and tumorous enlargement of the left testis, left inguinal orchectomy and right orchectomy were performed. Metastatic dissemination of prostate adenocarcinoma into a testis was determined by a pathohistological analysis of the left testis. Conclusion: The metastasis of the prostate carcinoma into a testis, as a rare localization of the metastatic dissemination, after additionally performed orchectomy along with further oncological therapy, can provide a continuation of a good life quality as well as a control of the disease in a longer time period.

    Main goal in the management of patients with severe traumatic brain injury (TBI) is control of intracranial pressure (ICP). Decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe TBI. Because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. We herein report a case of severe TBI in a 13-year-old boy treated by cisternostomy. The patient was admitted following a motor vehicle accident. Brain CT scan showed diffuse brain edema, left frontal contusion and posterior interhemispheric subdural hematoma. The patient underwent ICP monitoring. Subsequently, with 26 mmHg mean-value of ICP, he was treated surgically by cisternostomy technique. A progressive improvement of the neurological conditions in the following hours. After 5 days the boy was discharged and in the 3-months follow-up he was completely recovered. Cisternostomy could be an appropriate alternative to decompressive craniectomy for management of intracranial hypertension in patietns with sever TBI. PMID:27540551

    Mycotic aneurysm of external carotid artery is extremely rare. We herein report a case of external carotid artery (ECA) aneurysm following severe traumatic brain injury. A 24-year-old man with severe traumatic brain injury (TBI) following a car accident was referred to Rajaee Trauma Center Emergency Room affiliated to Shiraz University of Medical Sciences in Shiraz, Iran. He underwent ventriculostomy on arrival for intracerebral pressure (ICP) monitoring and for a second time due to hydrocephalus following decompressive craniectomy. He developed fulminant meningitis and ventriculitis during his hospital course. A bulged pulsatile lesion under the frontotemporal scalp resulted into the suspicion to underlying vascular pathology. Six-vessel angiography of brain was done which revealed mycotic aneurysm of external carotid artery. The patient underwent a two-week course of a combination of intravenous antibiotics. Follow-up angiography was performed which confirmed successful treatment of mycotic aneurysm of ECA. Mycotic aneurysm of ECA is extremely rare. To our knowledge, this is the first report of mycotic aneurysm of ECA following severe TBI which was successfully treated with antimicrobial therapy.

    Operant conditioning-based behavioural interventions are commonly used for the behavioural problems of individuals with mental retardation. There is also growing evidence of the benefits of these interventions for treating some of the behavioural problems of individuals with acquired cognitive deficits resulting from brain trauma. However, the effects of behavioural interventions on behavioural problems occurring during acute neurorehabilitation, when orientation and memory are most impaired, have not been studied. In this empirical case study, operant conditioning-based procedures were applied with an 8-year-old girl recovering from brain trauma and related neurosurgery. Screaming, non-compliance and aggression, which were disrupting rehabilitation therapies and follow-up neuroimaging, were treated using differential positive reinforcement techniques. Beneficial behavioural intervention effects were demonstrated using single-subject experimental methods. Aberrant behaviour during physical and occupational therapies was reduced, and cooperation with a computerized tomography (CT) scan without sedation was accomplished using operant behavioural intervention. Results support the use of operant interventions early in recovery from brain trauma, and highlight the importance of interdisciplinary collaboration for the implementation and further study of early behavioural interventions.

    Background Gastrointestinal neuroendocrine tumors (GI-NETs) are potentially malignant tumors, and their most common location of metastasis is the liver. Objectives In this report, we will describe our experience with some clinical and pathologic findings of hepatic metastasis in a group of cases of GI-NETs at the largest referral center of GI and liver diseases in south Iran. Materials and Methods In this four-year study (2011 - 2014), all GI and liver NETs were extracted from the pathology files of hospitals affiliated with Shiraz University of Medical Sciences. After classification based on the world health organization guidelines, the patients were evaluated according to their location, sex, age, and proliferative index. After studying the imaging and clinical charts of liver-NET cases with an unknown primary location, a complete panel of immunohistochemical markers (TTF-1, CDX-2, CK-7, CK-2, etc.) was used to find the primary GI location. Carcinoid tumors from other sites, such as the lung, were omitted from this study. Results The most common primary site of metastatic GI-NET to the liver in our center was the small intestine, which was also the most frequent location of GI-NET without liver metastasis. No cases of appendiceal-NET were found with liver metastasis. In 8 cases (11.6%) with liver-NETs, no primary location was identified. GI-NETs with liver metastasis had a significantly higher grade and proliferative index compared with NETs without liver metastasis. Conclusions Liver metastasis of neuroendocrine tumors in Iran presents in a very similar manner as that seen in western countries. In about 89% of cases with liver-NET, complete imaging, clinical, and pathological studies can help to identify the primary origin of the liver-NET, which is very important in the patient’s management.

    Metastatic disease is the leading cause of cancer-related deaths and involves critical interactions between tumor cells and the microenvironment. Hypoxia is a potent microenvironmental factor promoting metastatic progression. Clinically, hypoxia and the expression of the hypoxia-inducible transcription factors HIF-1 and HIF-2 are associated with increased distant metastasis and poor survival in a variety of tumor types. Moreover, HIF signaling in malignant cells influences multiple steps within the metastatic cascade. Here we review research focused on elucidating the mechanisms by which the hypoxic tumor microenvironment promotes metastatic progression. These studies have identified potential biomarkers and therapeutic targets regulated by hypoxia that could be incorporated into strategies aimed at preventing and treating metastatic disease.

    Objectives Nodding syndrome is a devastating neurological disorder of uncertain aetiology affecting children in Africa. There is no diagnostic test, and risk factors and symptoms that would allow early diagnosis are poorly documented. This study aimed to describe the clinical, electrophysiological and brain imaging (MRI) features and complications of nodding syndrome in Ugandan children. Design Case series. Participants 22 children with nodding syndrome brought to Mulago National Referral Hospital for assessment. Outcome measures Clinical features, physical and functional disabilities, EEG and brain MRI findings and a staging system with a progressive development of symptoms and complications. Results The median age of symptom onset was 6 (range 4–10) years and median duration of symptoms was 8.5 (range 2–11) years. 16 of 22 families reported multiple affected children. Physical manifestations and complications included stunting, wasting, lip changes and gross physical deformities. The bone age was delayed by 2 (range 1–6) years. There was peripheral muscle wasting and progressive generalised wasting. Four children had nodding as the only seizure type; 18 in addition had myoclonic, absence and/or generalised tonic–clonic seizures developing 1–3 years after the onset of illness. Psychiatric manifestations included wandering, aggression, depression and disordered perception. Cognitive assessment in three children demonstrated profound impairment. The EEG was abnormal in all, suggesting symptomatic generalised epilepsy in the majority. There were different degrees of cortical and cerebellar atrophy on brain MRI, but no hippocampal changes. Five stages with worsening physical, EEG and brain imaging features were identified: a prodrome, the development of head nodding and cognitive decline, other seizure types, multiple complications and severe disability. Conclusions Nodding syndrome is a neurological disorder that may be characterised as probably

    Summary Background It is well known that traumatic brain injury often changes the way the patient perceives reality, which often means a distortion of the perception of self and the world. The purpose of this article is to understand the processes of identity change after traumatic brain injury. Case Report We describe progressive deterioration in personal identity in a former physician who had sustained a serious head injury (1998), resulting in focal injuries to the right frontal and temporal areas. He regained consciousness after 63 days in coma and 98 days of post-traumatic amnesia, but has since displayed a persistent loss of autobiographical memory, self-image, and emotional bonds to family and significant others. Qualitative ‘life-story’ interviewing was undertaken to explore the mental state of a patient whose subjective, “first person” identity has been disengaged, despite the retention of significant amounts of objective, “third person” information about himself and his personal history (though this was also lost at a later stage in the patient’s deterioration). Identity change in our patient was characterized by a dynamic and convoluted process of contraction, expansion and tentative balance. Our patient tends to cling to the self of others, borrowing their identities at least for the period he is able to remember. Identity is closely connected with the processes of memory. Conclusions The results will be examined in relation to the microgenetic theory of brain function. The brain mechanisms that may account for these impairments are discussed. Findings from this study have important implications for the delivery of person-focused rehabilitation. PMID:21278697

    Methamphetamine (METH) is a highly addictive drug of abuse and toxic to the brain. Recent studies indicated that besides direct damage to dopamine and 5-HT terminals, neurotoxicity of METH may also result from its ability to modify the structure of blood-brain barrier (BBB). The present study investigated the postmortem brain mRNA and immunohistochemical expressions of matrix metalloproteases (MMPs), claudin5 (CLDN5), and aquaporins (AQPs) in forensic autopsy cases of carbon monoxide (n = 14), METH (n = 21), and phenobarbital (n = 17) intoxication, compared with mechanical asphyxia (n = 15), brain injury (n = 11), non-brain injury (n = 21), and sharp instrument injury (n = 15) cases. Relative mRNA quantification using Taqman real-time PCR assay demonstrated higher expression of AQP4 and MMP9, lower expression of CLDN5 in METH intoxication cases and lower expression of MMP2 in phenobarbital intoxication cases. Immunostaining results showed substantial interindividual variations in each group, showing no evident differences in distribution or intensity among all the causes of death. These findings suggest that METH may increase BBB permeability by altering CLDN5 and MMP9, and the self-protective system maybe activated to eliminate accumulating water from the extracellular space of the brain by up-regulating AQP4. Systematic analysis of gene expressions using real-time PCR may be a useful procedure in forensic death investigation.

    Nonmissile penetrating intracranial injuries are uncommon events in modern times. Most reported cases describe trajectories through the orbit, skull base foramina, or areas of thin bone such as the temporal squama. Patients who survive such injuries and come to medical attention often require foreign body removal. Critical neurovascular structures are often damaged or at risk of additional injury resulting in further neurological deterioration, life-threatening hemorrhage, or death. Delayed complications can also be significant and include traumatic pseudoaneurysms, arteriovenous fistulas, vasospasm, cerebrospinal fluid leak, and infection. Despite this, given the rarity of these lesions, there is a paucity of literature describing the management of neurovascular injury and skull base repair in this setting. The authors describe three cases of nonmissile penetrating brain injury and review the pertinent literature to describe the management strategies from a contemporary cerebrovascular and skull base surgery perspective.

    Music is among all cultures an important part of the live of most people. Music has psychological benefits and may generate strong emotional and physiological responses. Recently, neuroscientists have discovered that music influences the reward circuit of the nucleus accumbens (NAcc), even when no explicit reward is present. In this clinical case study, we describe a 60-year old patient who developed a sudden and distinct musical preference for Johnny Cash following deep brain stimulation (DBS) targeted at the NAcc. This case report substantiates the assumption that the NAcc is involved in musical preference, based on the observation of direct stimulation of the accumbens with DBS. It also shows that accumbens DBS can change musical preference without habituation of its rewarding properties. PMID:24834035

    The site of crucial damage that causes acquired apraxia of speech (AOS) has been debated in the literature. This study presents five in-depth cases that offer insight into the role of brain areas involved in AOS. Four of the examined participants had a primary impairment of AOS either with (n = 2) or without concomitant mild aphasia (n = 2). The fifth participant presented with a lesion relatively isolated to the left anterior insula (AIns-L), damage that is rarely reported in the literature, but without AOS. Taken together, these cases challenge the role of the AIns-L and implicate the left motor regions in AOS. PMID:27264534

    Few cases of trigeminal neuralgia (TGN) induced by brain arteriovenous malformations (bAVMs) have previously been reported. The present case report described one case of TGN caused by bAVMs in a 32-year-old male patient who suffered from recurrent pain in his right cheek for a period of two years, for whom the seizure frequency and duration of pain increased for 6 months. Magnetic resonance imaging was performed, which demonstrated flow-void signals in the abnormal vessels in the right cerebellopontine angle. Subsequent digital subtraction angiography confirmed the diagnosis of bAVMs, and showed the nidus was fed by the right superior cerebellar and the right anterior inferior cerebellar, and drained into the adjacent venous sinuses on the same side. The patient underwent an interventional embolization treatment. TGN was completely relieved following embolization of the majority of the bAVMs. Pain relief may be associated with blocking of the pulsatile compression of the feeding arteries of the bAVMs, the arterialized draining veins or the malformed niduses following embolization, which is similar to the effects induced by microvascular decompression surgery of the trigeminal nerve. In the present case study and review, the underlying mechanism and treatment strategy of TGN caused by bAVMs were discussed in the context of present case, and a literature review was carried out.

    2014-01-01

    Introduction Cerebral salt-wasting syndrome is a condition featuring hyponatremia and dehydration caused by head injury, operation on the brain, subarachnoid hemorrhage, brain tumor and so on. However, there are a few reports of cerebral salt-wasting syndrome caused by cerebral infarction. We describe a patient with cerebral infarction who developed cerebral salt-wasting syndrome in the course of hemorrhagic transformation. Case presentation A 79-year-old Japanese woman with hypertension and arrhythmia was admitted to our hospital for mild consciousness disturbance, conjugate deviation to right, left unilateral spatial neglect and left hemiparesis. Magnetic resonance imaging revealed a broad ischemic change in right middle cerebral arterial territory. She was diagnosed as cardiogenic cerebral embolism because atrial fibrillation was detected on electrocardiogram on admission. She showed hyponatremia accompanied by polyuria complicated at the same time with the development of hemorrhagic transformation on day 14 after admission. Based on her hypovolemic hyponatremia, she was evaluated as not having syndrome of inappropriate secretion of antidiuretic hormone but cerebral salt-wasting syndrome. She fortunately recovered with proper fluid replacement and electrolyte management. Conclusions This is a rare case of cerebral infarction and cerebral salt-wasting syndrome in the course of hemorrhagic transformation. It may be difficult to distinguish cerebral salt-wasting syndrome from syndrome of inappropriate antidiuretic hormone, however, an accurate assessment is needed to reveal the diagnosis of cerebral salt-wasting syndrome because the recommended fluid management is opposite in the two conditions.

    Paroxysmal sympathetic hyperactivity (PSH) is a condition in which there is extreme autonomic dysregulation leading to multiple episodes of sympathetic hyperactivity. Its occurrence after traumatic brain injury (TBI) in pediatric population is a neglected scenario. In our series, all pediatric patients with moderate and severe head injuries were studied and those patients who developed PSH were monitored for the PSH episodes. Four children out of 36 cases of pediatric severe traumatic brain injury developed features of PSH. Admission GCS of 3 children were 4/15 and 1 child was 6/15 and each of them had an ICU stay of more than 2 weeks and a poor DRS score at discharge. The presence of PSH is known to produce poorer outcome in terms of overall mortality, time needed for recovery, chances of developing infections, etc. which was also seen in these cases presented here. Though some studies have provided guidelines for the management of PSH like symptomatic management and use of drugs like clonidine, bromocriptine, benzodiazepines, and gabapentin, strict management guidelines are not established and exact incidence in pediatric population is not determined.

    An estimated 30% of individuals with autism spectrum disorders (ASD) remain minimally verbal into late childhood, but research on cognition and brain function in ASD focuses almost exclusively on those with good or only moderately impaired language. Here we present a case study investigating auditory processing of GM, a nonverbal child with ASD and cerebral palsy. At the age of 8 years, GM was tested using magnetoencephalography (MEG) whilst passively listening to speech sounds and complex tones. Where typically developing children and verbal autistic children all demonstrated similar brain responses to speech and nonspeech sounds, GM produced much stronger responses to nonspeech than speech, particularly in the 65–165 ms (M50/M100) time window post-stimulus onset. GM was retested aged 10 years using electroencephalography (EEG) whilst passively listening to pure tone stimuli. Consistent with her MEG response to complex tones, GM showed an unusually early and strong response to pure tones in her EEG responses. The consistency of the MEG and EEG data in this single case study demonstrate both the potential and the feasibility of these methods in the study of minimally verbal children with ASD. Further research is required to determine whether GM's atypical auditory responses are characteristic of other minimally verbal children with ASD or of other individuals with cerebral palsy.

    The study aimed to highlight the importance of interdisciplinary collaboration and the value for combining normative neuropsychological and neuroradiological measures for clinical purposes. We present the case of "CL," a 65-year-old, right-handed, Caucasian female referred for a neuropsychological evaluation of memory difficulties and depression with the rule-out of pseudodementia. A brain magnetic resonance imaging (MRI) scan was conducted within 24 hours of the neuropsychology exam. Mood measures showed elevated depression and apathy symptoms. The neuropsychological profile showed variable effort, intact comprehension but compromised confrontation naming and verbal memory deficits. Using normative references from 20 female age- and education-matched healthy control peers, CL showed significantly reduced temporal cortex thickness with reduced bilateral hippocampal, right amygdala, and right caudate volumes. Combined data were supportive of a diagnosis of semantic dementia. Examining neuropsychological profiles in combination with neuroimaging standardized metrics relative to peers improved case conceptualization. Standard measures of effort and malingering examined alone and without MRI for the diagnosis of pseudodementia have questionable validity and rationale. We additionally discuss the advantages and limitations/challenges for integrating neuropsychological assessments with normative based MRI brain metrics.

    To provide histological diagnoses of brain diseases, CT-guided stereotactic brain biopsy (CT-SBB) has been widely used because of its less invasive technique compared with open brain biopsy (OBB). However, CT-SBB is not always diagnostic. We report a case of multiple intracranial tuberculoma whose diagnosis was not made by CT-SBB but by OBB. The patient is a 46-year-old man with insulin-dependent diabetes mellitus who had been receiving immunosuppressive agents (azathioprine, cyclosporin, and prednisolone) after renal transplantation for diabetic renal failure for 9 years. He gradually developed febrile, headache and unsteady gait. Brain MRI demonstrated multiple intracranial lesions involving left fronto-temporal and right parietal lobes, left cerebellar hemisphere, and the fourth ventricle. Although the MRI findings were consistent with those of previously reported cases of intracranial tuberculoma, other conditions, such as malignant lymphoma and toxoplasmosis, were not ruled out. Therefore, CT-SBB targeting the left temporal lobe lesion was done for definitive diagnosis, but it revealed only mild perivascular infiltration of mononuclear cells and hemorrhage. He was transferred to our clinic for further evaluation. On examination, mild truncal and limb ataxia on the left were noted in addition to the neurological findings corresponding to diabetic retinopathy and neuropathy. Despite vigorous laboratory examinations, including repeated bacterial cultures and PCR of cerebrospinal fluid, no evidence of tuberculous infection was obtained. A tentative diagnosis of multiple intracranial tuberculoma was made, and anti-tuberculous drugs (isoniazid 400 mg, ethambutol 750 mg, and pyrazinamide 1.5 g) were administered. Since his symptoms deteriorated because of ventricular dilatation resulting from the enlarged lesion in the fourth ventricle after a temporary clinical improvement, VP-shunting and OBB from the left temporal lobe lesion were done. The excised lesion was

    Cerebral and cerebellar symptoms are frequently associated with Legionnaires' disease. However, corresponding brain lesions are difficult to demonstrate using either computed tomography (CT) or magnetic resonance imaging (MRI). We report here two patients with Legionella pneumophila pneumonia accompanied by prolonged neurologic symptoms. In contrast to brain CT and MRI, which failed to detect any abnormalities, single-photon emission computed tomography (SPECT) showed multiple sites of hypoperfusion within the brains of both patients. These cases suggest that vasculopathy, which is detectable by SPECT, might be one of the causes of neurologic symptoms in patients with Legionnaires' disease. PMID:27478660

    Renal cell carcinomas account for 2–3% of malignant neoplasms in adults. The lung, soft tissues and bone represent the most frequent sites of distant metastasis in renal cell carcinoma. Gastric metastasis is rare. Our case was a 72-year-old man with complaints of fatigue and loss of appetite. In history, he had unergone radical nephrectomy due to renal cell carcinoma in 1993. A polypoid lesion was observed in upper gastrointestinal endoscopy. Histopathology of gastric biopsy specimen was reported as renal cell carcinoma. In English literature, there are 50 cases diagnosed as gastric metastasis from renal cell carcinoma. To date, there are only 4 cases with extremely late gastric metastasis of renal cell carcinoma. Herein, we present a rare case which underwent radical nephrectomy due to renal cell carcinoma and found to have gastric metastasis at 20. year of his follow-up. PMID:27274897

    Music evoked autobiographical memories (MEAMs) have been characterised in the healthy population, but not, to date, in patients with acquired brain injury (ABI). Our aim was to investigate music compared with verbal evoked autobiographical memories. Five patients with severe ABI and matched controls completed the experimental music (MEAM) task (a written questionnaire) while listening to 50 "Number 1 Songs of the Year" (from 1960 to 2010). Patients also completed the Autobiographical Memory Interview (AMI) and a standard neuropsychological assessment. With the exception of Case 5, who reported no MEAMs and no autobiographical incidents on the AMI and who also had impaired pitch perception, the range of frequency and type of MEAMs in patients was broadly in keeping with their matched controls. The relative preservation of MEAMs in four cases was particularly noteworthy given their impaired verbal and/or visual anterograde memory, and in three cases, autobiographical memory impairment. The majority of MEAMs in both cases and matched controls were of a person/people or a period of life. In three patients music was more efficient at evoking autobiographical memories than the AMI verbal prompts. This is the first study of MEAMs after ABI. The findings suggest that music is an effective stimulus for eliciting autobiographical memories, and may be beneficial in the rehabilitation of autobiographical amnesia, but only in patients without a fundamental deficit in autobiographical recall memory and intact pitch perception.

    We reported two cases of hepatocellular carcinoma (HCC) with lung metastases who were treated with a combination of thalidomide and cyproheptadine. The use of cyproheptadine in these two cases was originally for skin itching. Follow-up CT images revealed a complete remission of HCC in both of them after treatment for 6 months and 6 weeks, respectively. A following experimental cell line study demonstrated that cyproheptadine effectively reduced the viability of two HCC cell lines.

    Ovarian cancer is the most lethal gynecological malignancy. It is usually diagnosed at a late stage, with a 5-yr survival rate of <30%. The majority of ovarian cancer cases are diagnosed after tumors have widely spread within the peritoneal cavity, limiting the effectiveness of debulking surgery and chemotherapy. Owing to a substantially lower survival rate at late stages of disease than at earlier stages, the major cause of ovarian cancer deaths is believed to be therapy-resistant metastasis. Although metastasis plays a crucial role in promoting ovarian tumor progression and decreasing patient survival rates, the underlying mechanisms of ovarian cancer spread have yet to be thoroughly explored. For many years, researchers have believed that ovarian cancer metastasizes via a passive mechanism by which ovarian cancer cells are shed from the primary tumor and carried by the physiological movement of peritoneal fluid to the peritoneum and omentum. However, the recent discovery of hematogenous metastasis of ovarian cancer to the omentum via circulating tumor cells instigated rethinking of the mode of ovarian cancer metastasis and the importance of the "seed-and-soil" hypothesis for ovarian cancer metastasis. In this review we discuss the possible mechanisms by which ovarian cancer cells metastasize from the primary tumor to the omentum, the cross-talk signaling events between ovarian cancer cells and various stromal cells that play crucial roles in ovarian cancer metastasis, and the possible clinical implications of these findings in the management of this deadly, highly metastatic disease.

    We present the case of a 66-year-old man who has been treated for essential tremor since the age of 58. He developed mild cerebellar gait ataxia seven years after tremor onset. Moderate, global brain atrophy was identified on MRI scans. At the age of 68, only temporary tremor relief could be achieved by bilateral deep brain stimulation of the ventral intermedius nucleus of the thalamus. Bilateral stimulation of the subthalamic nucleus also resulted only in transient improvement. In the meantime, progressive gait ataxia and tetraataxia developed accompanied by other cerebellar symptoms, such as nystagmus and scanning speech. These correlated with progressive development of bilateral symmetric hyperintensity of the middle cerebellar peduncles on T2 weighted MRI scans. Genetic testing revealed premutation of the FMR1 gene, establishing the diagnosis of fragile X-associated tremor/ataxia syndrome. Although this is a rare disorder, it should be taken into consideration during preoperative evaluation of essential tremor. Postural tremor ceased two years later after thalamotomy on the left side, while kinetic tremor of the right hand also improved.
