  1. Locally Advanced Lung Cancer: An Optimal Setting for Vaccines and Other Immunotherapies

    2013-01-01

    Lung cancer has traditionally been considered relatively resistant to immunotherapies. However, recent advances in the understanding of tumor-associated antigens, anti-tumor immune responses, and tumor immunosuppression mechanisms have resulted in a number of promising immunomodulatory therapies such as vaccines and checkpoint inhibitors. Locally advanced non-small cell lung cancer (NSCLC) is an optimal setting for these treatments because standard therapies such as surgery, radiation, and chemotherapy may enhance anti-tumor immune effects by debulking the tumor, increasing tumor antigen presentation, and promoting T-cell response and trafficking. Clinical trials incorporating immunomodulatory agents into combined modality therapy of locally advanced NSCLC have shown promising results. Future challenges include identifying biomarkers to predict those patients most likely to benefit from this approach, radiographic assessment of treatment effects, the timing and dosing of combined modality treatment including immunotherapies, and avoidance of potentially overlapping toxicities.

    Childhood sexual abuse (CSA) is a common, distressing, yet rarely discussed topic in palliative care. The long-term effects of CSA can have a significant impact on patients' quality of life, particularly at the end of life. In this article, we aim to initiate a discussion regarding the need to address CSA in the palliative care setting, using the example of an advanced cancer patient and her caregiver sister who revealed their common past. Specifically, we will be discussing 1) the comorbidities, psychological distress, and family distress associated with CSA, 2) its impact on health care delivery, 3) an approach to initiating conversations regarding CSA, and 4) various management strategies. Successful management of CSA necessitates an interprofessional team approach and may help to improve the quality of life of patients and their families.

    Our goal was to determine the clinical treatment response following radiation administered with or without chemotherapy for locally advanced cervical cancers in Honduras. This is a retrospective study of patients treated with either concurrent chemoradiation (CCRT) or external beam radiation therapy (EBRT) alone at a hospital in Tegucigalpa, Honduras. 70 Gy of EBRT to the pelvis was given in all cases. Brachytherapy was not available. Chemotherapy was given when available. Extrafascial hysterectomy was performed 6 weeks after completion of treatment in patients with a complete clinical response (cCR). Records for 165 women with locally advanced cervical cancer were reviewed; 25 (15.2%) stage IB2, 15 (9.1%) stage IIA, 90 (54.5%) stage IIB, and 35 (21.2%) stage IIIB. Ninety (54.5%) patients received EBRT alone; 75 (45.5%) received CCRT. Twenty-three (33.3%) of CCRT patients received weekly cisplatin, the remainder receiving other agents. Seventy (77.8%) of the 90 patients who received EBRT had a cCR; 25 out of 75 (33.3%) patients in the CCRT group achieved a cCR. The CCRT group treated with weekly cisplatin achieved an 80% cCR; while the CCRT group given alternative agents had only a 31% cCR. Patients unable to receive platinum-based CCRT had the worst outcome, and their responses were inferior to patients who received EBRT. The challenges of treating women with locally advanced cervical cancer in a low-resource setting are multifactorial and include treatment delays, the lack of brachytherapy and the unpredictable availability of chemotherapy.

    2013-01-01

    Radiotherapy has a longstanding and well-defined role in the treatment of resectable rectal cancer to reduce the historically high risk of local recurrence. In more advanced borderline or unresectable cases, where the circumferential resection margin (CRM) is breached or threatened according to magnetic resonance imaging (MRI), despite optimized local multimodality treatment and the gains achieved by modern high quality total mesorectal excision (TME), at least half the patients fail to achieve sufficient downstaging with current schedules. Many do not achieve an R0 resection. In less locally advanced cases, even if local control is achieved, this confers only a small impact on distant metastases and a significant proportion of patients (30-40%) still subsequently develop metastatic disease. In fact, distant metastases have now become the predominant cause of failure in rectal cancer. Therefore, increasing the intensity and efficacy of chemotherapy and chemoradiotherapy by integrating additional cytotoxics and biologically targetted agents seems an appealing strategy to explore—with the aim of enhancing curative resection rates and improving distant control and survival. However, to date, we lack validated biomarkers for these biological agents apart from wild-type KRAS. For cetuximab, the appearance of an acneiform rash is associated with response, but low levels of magnesium appear more controversial. There are no molecular biomarkers for bevacizumab. Although some less invasive clinical markers have been proposed for bevacizumab, such as circulating endothelial cells (CECS), circulating levels of VEGF and the development of overt hypertension, these biomarkers have not been validated and are observed to emerge only after a trial of the agent. We also lack a simple method of ongoing monitoring of ‘on target’ effects of these biological agents, which could determine and pre-empt the development of resistance, prior to radiological and clinical assessessments

    The treatment of breast cancer has made significant improvements during the past ten years. For early breast cancer with a clinically negative axilla sentinel node biopsy has become the preferred approach. For endocrine therapy of postmenopausal patients the selective aromatase inhibitors have become standard in metastatic as well as in early breast cancer. Trastuzumab (Herceptin) plays an important role in the treatment of HER2-positive breast cancer in the metastatic and since 2005 also in the adjuvant setting. When chemotherapy is used to treat metastatic breast cancer drug combinations are superior to monotherapy only in terms of response rates. By contrast, in the adjuvant setting combination drug therapy is the standard. New methods of tissue analysis including expression patterns of mRNA and proteins are promising research strategies to further advance the field.

    Context Cancer screening has been integrated into routine primary care but does not benefit patients with limited life expectancy. Objective To evaluate the extent to which patients with advanced cancer continue to be screened for new cancers. Design, Setting, and Participants Utilization of cancer screening procedures (mammography, Papanicolaou test, prostate-specific antigen [PSA], and lower gastrointestinal [GI] endoscopy) was assessed in 87 736 fee-for-service Medicare enrollees aged 65 years or older diagnosed with advanced lung, colorectal, pancreatic, gastroesophageal, or breast cancer between 1998 and 2005, and reported to one of the Surveillance, Epidemiology, and End Results (SEER) tumor registries. Participants were followed up until death or December 31, 2007, whichever came first. A group of 87 307 Medicare enrollees without cancer were individually matched by age, sex, race, and SEER registry to patients with cancer and observed over the same period to evaluate screening rates in context. Demographic and clinical characteristics associated with screening were also investigated. Main Outcome Measure For each cancer screening test, utilization rates were defined as the percentage of patients who were screened following the diagnosis of an incurable cancer. Results Among women following advanced cancer diagnosis compared with controls, at least 1 screening mammogram was received by 8.9% (95% confidence interval [CI], 8.6%-9.1%) vs 22.0% (95% CI, 21.7%-22.5%); Papanicolaou test screening was received by 5.8% (95% CI, 5.6%-6.1%) vs 12.5% (95% CI, 12.2%-12.8%). Among men following advanced cancer diagnosis compared with controls, PSA test was received by 15.0% (95% CI, 14.7%-15.3%) vs 27.2% (95% CI, 26.8%-27.6%). For all patients following advanced diagnosis compared with controls, lower GI endoscopy was received by 1.7% (95% CI, 1.6%-1.8%) vs 4.7% (95% CI, 4.6%-4.9%). Screening was more frequent among patients with a recent history of screening (16.2% [95

    Background Epithelial growth factor receptor inhibitors (EGFRis) and bevacizumab (BEV) are used in combination with chemotherapy for the treatment of metastatic colorectal cancer (mCRC). However, few randomized controlled trials (RCTs) have directly compared their relative efficacy on progression-free survival (PFS) and overall survival (OS). Methods We conducted a systematic review of first-line RCTs comparing (1) EGFRis vs. BEV, with chemotherapy in both arms (2) EGFRis + chemotherapy vs. chemotherapy alone, or (3) BEV + chemotherapy vs. chemotherapy alone, using Cochrane methodology. Data on and PFS and OS were extracted using the Parmar method. Pairwise meta-analyses and Bayesian network meta-analyses (NMA) were conducted to estimate the direct, indirect and combined PFS and OS hazard ratios (HRs) comparing EGFRis to BEV. Results Seventeen RCTs contained extractable data for quantitative analysis. Combining direct and indirect data using an NMA did not show a statistical difference between EGFRis versus BEV (PFS HR = 1.11 (95% CR: 0.92–1.36) and OS HR = 0.91 (95% CR: 0.75–1.09)). Direct meta-analysis (3 RCTs), indirect (14 RCTs) and combined (17 RCTs) NMA of PFS HRs were concordant and did not show a difference between EGFRis and BEV. Meta-analysis of OS using direct evidence, largely influenced by one trial, showed an improvement with EGFRis therapy (HR = 0.79 (95% CR: 0.65–0.98)), while indirect and combined NMA of OS did not show a difference between EGFRis and BEV Successive inclusions of trials over time in the combined NMA did not show superiority of EGFRis over BEV. Conclusions Our findings did not support OS or PFS benefits of EGFRis over BEV in first-line mCRC. PMID:26474403

    Endometrial cancer is the most common gynecologic malignancy in the United States, with yearly rates continuing to increase. Most women present with early stage disease; however, advanced disease carries a grave prognosis. As a result, novel therapies are currently under investigation for the treatment of endometrial cancer. These advances include a better understanding of the genetic basis surrounding the development of endometrial cancer, novel surgical therapies, and new molecular targets for the treatment of this disease. This review explores the literature regarding these advancements in endometrial cancer. PMID:28184290

    Purpose: Little is known regarding toxicities and hospitalizations in community-based settings for patients with advanced non–small-cell lung cancer (NSCLC) who received commonly prescribed carboplatin-paclitaxel (CP) or carboplatin-paclitaxel-bevacizumab (CPB) chemotherapy. Methods: Patients with stages IIIB-IV NSCLC age ≥ 21 years diagnosed between 2005 and 2010 who received first-line CP or CPB were identified at four health maintenance organizations (N = 1,109). Using patient and tumor characteristics and hospital and ambulatory encounters from automated data in the 180 days after chemotherapy initiation, the association between CP and CPB and toxicities and hospitalizations were evaluated with χ2 tests and propensity score–adjusted regression models. Results: Patients who received CPB were significantly younger and had significantly more bleeding, proteinuria, and GI perforation events (all P < .05). For these patients, the unadjusted odds ratio associated with the likelihood of having a hospitalization was 0.46 (95% CI, 0.32 to 0.67). As shown by multivariable and propensity score–adjusted models, patients who received CPB were less likely to have been hospitalized (odds ratio, 0.48; 95% CI, 0.32 to 0.71) and had fewer total hospitalizations (rate ratio, 0.62; 95% CI, 0.47 to 0.82) and hospital days (rate ratio, 0.53; 95% CI, 0.47 to 0.60) than patients who received CP. Conclusion: Consistent with earlier randomized clinical trials, significantly more toxicity events were identified in patients treated with CPB. However, both unadjusted and adjusted models showed that patients who received CPB were less likely than patients who received CP to experience a hospital-related event after the initiation of chemotherapy. Findings here confirm the need for adherence to clinical recommendations for judicious use of CPB, but provide reassurance regarding the relative risk for hospitalizations. PMID:26060223

    2016-02-01

    After decades of setbacks, cancer immunology is living its Golden Age. Recent advances in cancer immunology have provided new therapeutic approaches to treat cancer. The objective clinical response observed in patients treated with antibodies that block the immune checkpoints, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell-death protein 1 (PD-1)/programmed cell-death 1 ligand 1 (PD-L1) pathways, has led to their FDA approval for the treatment of melanoma in 2011 and in 2014, respectively. The anti-PD-1 antibody nivolumab has received the FDA-approval in March 2015 for squamous lung cancer treatment. In addition, antibodies targeting PD-1 or PD-L1 have demonstrated their efficacy and safety in additional tumors, including non-small cell lung carcinoma (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's lymphoma. Almost at the same time, the field of adoptive cell transfer has exploded. The chimeric antigen receptor (CAR) T technology has provided strong evidence of efficacy in the treatment of B cell malignancies, and different T cell based treatments are currently under investigation for different types of tumors. In this review we will discuss the latest advances in cancer immunology and immunotherapy as well as new treatments now under development in the clinic and potential strategies that have shown promising results in preclinical models.

    2015-01-01

    To evaluate MRI for neoadjuvant therapy response assessment in locally advanced rectal cancer (LARC) using dynamic contrast enhanced-MRI (DCE-MRI) and diffusion weighted imaging (DWI), we have compared magnetic resonance volumetry based on DCE-MRI (V(DCE)) and on DWI (V(DWI)) scans with conventional T2-weighted volumetry (V(C)) in LARC patients after neoadjuvant therapy. Twenty-nine patients with LARC underwent MR examination before and after neoadjuvant therapy. A manual segmentation was performed on DCE-MR postcontrast images, on DWI (b-value 800 s/mm2), and on conventional T2-weighted images by two radiologists. DCE-MRI, DWI, and T2-weigthed volumetric changes before and after treatment were evaluated. Nonparametric sample tests, interobserver agreement, and receiver operating characteristic curve (ROC) were performed. Diagnostic performance linked to DCE-MRI volumetric change was superior to T2-w and DW-MRI volumetric changes performance (specificity 86%, sensitivity 93%, and accuracy 93%). Area Under ROC (AUC) of V(DCE) was greater than AUCs of V(C) and V(DWI) resulting in an increase of 15.6% and 11.1%, respectively. Interobserver agreement between two radiologists was 0.977, 0.864, and 0.756 for V(C), V(DCE), and V(DWI), respectively. V(DCE) seems to be a promising tool for therapy response assessment in LARC. Further studies on large series of patients are needed to refine technique and evaluate its potential value. PMID:26413528

    Cough is a defense mechanism that prevents the entry of noxious materials into the respiratory system and clears foreign materials and excess secretions from the lungs and respiratory tract. In advanced cancer, it is a common symptom that interferes with the patient's daily activity and quality of life. Empiric treatment with antitussive agents is often needed. Two classes of antitussive drugs are available: (1) centrally acting: (a) opioids and (b) non-opioids; (2) peripherally acting: (a) directly and (b) indirectly. Antitussive availability varies widely around the world. Many antitussives, such as benzonatate, codeine, hydrocodone, and dextromethorphan, were extensively studied in the acute and chronic cough settings and showed relatively high efficacy and safety profiles. Benzonatate, clobutinol, dihydrocodeine, hydrocodone, and levodropropizine were the only antitussives specifically studied in cancer and advanced cancer cough. They all have shown to be effective and safe in recommended daily dose for cough. In advanced cancer the patient's current medications, previous antitussive use, the availability of routes of administration, any history of drug abuse, the presence of other symptoms and other factors, all have a role in the selection of antitussives for prescription. A good knowledge of the pharmacokinetics, dosage, efficacy, and side effects of the available antitussives provides for better management.

    Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC), and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer). Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0) resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options. PMID:27785074

    Four out of five children diagnosed with cancer can be cured with contemporary cancer therapy. This represents a dramatic improvement since 50 years ago when the cure rate of childhood cancer was <25% in the pre-chemotherapy era. Over the past ten years, while improvement in overall survival (OS) has been marginal, progress in pediatric oncology lies with adopting risk-adapted therapeutic approach. This has been made possible through identifying clinical and biologic prognostic factors with rigorous research and stratifying patients using these risk factors, and subsequently modifying therapy according to risk group assignment. This review provides a perspective for eight distinct pediatric malignancies, in which significant advances in treatment were made in the last decade and are leading to changes in standard of care. This includes four hematologic malignancies [acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL)] and four solid tumors [medulloblastoma (MB), low grade glioma (LGG), neuroblastoma (NB) and Ewing sarcoma (ES)]. Together, they comprise 60% of childhood cancer. Improved patient outcome is not limited to better survival, but encompasses reducing both short and long-term treatment-related complications which is as important as cure, given the majority of childhood cancer patients will become long-term survivors. Risk-adapted approach allows treatment intensification in the high-risk cohort while therapy can be de-escalated in the low-risk to minimize toxicity and late sequelae without compromising survival. Advances in medical research technology have also led to a rapid increase in the understanding of the genetics of childhood cancer in the last decade, facilitating identification of molecular targets that can potentially be exploited for therapeutic benefits. As we move into the era of targeted therapeutics, searching for novel agents that target specific genetic lesions becomes a

    The key points of this article are anorexia and cachexia are: A major cause of cancer deaths. Several drugs are available to treat anorexia and cachexia. Dyspnea in cancer usually is caused by several factors. Treatment consists of reversing underlying causes, empiric bronchodilators, cortico-steroids--and in the terminally ill patients-opioids, benzodiazepines,and chlorpromazine. Delirium is associated with advanced cancer. Empiric treatment with neuroleptics while evaluating for reversible causes is a reasonable approach to management. Nausea and vomiting are caused by extra-abdominal factors (drugs,electrolyte abnormalities, central nervous system metastases) or intra-abdominal factors (gastroparesis, ileus, gastric outlet obstruction, bowel obstruction). The pattern of nausea and vomiting differs depending upon whether the cause is extra- or intra-abdominal. Reversible causes should be sought and empiric metoclopramide or haloperidol should be initiated. Fatigue may be caused by anemia, depression, endocrine abnormalities,or electrolyte disturbances that should be treated before using empiric methylphenidate. Constipation should be treated with laxatives and stool softeners. Both should start with the first opioid dose.

    In the past decade, the power of harnessing T-cell co-signaling pathways has become increasingly understood to have significant clinical importance. In cancer immunotherapy, the field has concentrated on two related modalities: First, targeting cancer antigens through highly activated chimeric antigen T cells (CAR-Ts) and second, re-animating endogenous quiescent T cells through checkpoint blockade. In each of these strategies, the therapeutic goal is to re-ignite T-cell immunity, in order to eradicate tumors. In transplantation, there is also great interest in targeting T-cell co-signaling, but with the opposite goal: in this field, we seek the Yin to cancer immunotherapy's Yang, and focus on manipulating T-cell co-signaling to induce tolerance rather than activation. In this review, we discuss the major T-cell signaling pathways that are being investigated for tolerance induction, detailing preclinical studies and the path to the clinic for many of these molecules. These include blockade of co-stimulation pathways and agonism of coinhibitory pathways, in order to achieve the delicate state of balance that is transplant tolerance: a state which guarantees lifelong transplant acceptance without ongoing immunosuppression, and with preservation of protective immune responses. In the context of the clinical translation of immune tolerance strategies, we discuss the significant challenge that is embodied by the fact that targeted pathway modulators may have opposing effects on tolerance based on their impact on effector vs regulatory T-cell biology. Achieving this delicate balance holds the key to the major challenge of transplantation: lifelong control of alloreactivity while maintaining an otherwise intact immune system.

    Cervical cancer takes second place in morbidity and third place in mortality from gynecological cancer. Advanced stages among newly diagnosed cases is still large. The "gold standard" of treatment for locally advanced cervical cancer is chemoradiotherapy with cisplatin that results in a lower risk of death. Improvement of radiotherapy methods allowed to bring optimal dose to the primary tumor with the inclusion of regional metastasis areas with less risk of damage to surrounding healthy tissue and organs. The search for alternative combinations of cytostatics, modes of drug administration, adjuvant chemotherapy after chemoradiotherapy showed an increase in survival of patients with locally advanced cervical cancer.

    From July 1980 to June 1983, 61 postmenopausal women with progressive metastatic breast cancer were treated with aminoglutethimide, 250 mg 4 times daily, plus cortisone acetate, 25 mg twice daily. Of 51 evaluable patients, an objective remission was observed in 22 (43%) (partial remission in 19, complete in 3), stable disease in 14 (27%), and progressive disease in 15 (30%). The median duration of response was 60 weeks (range 12+; 94+). The response rate was higher when the dominant disease site was soft tissue (50%) or bone (56%) rather than viscera (29%). Side effects were common but usually slight and transient. Somnolence (69%), dizziness (41%), nausea (35%) and skin rash (27%) were the most frequent. Serum levels of gamma-GT, alkaline phosphatase and total cholesterol rose during aminoglutethimide treatment, whereas levels of uric acid and indirect bilirubin decreased. Aminoglutethimide plus cortisone acetate appears to be an active and relatively safe treatment in advanced breast cancer and may be recommended as second-line endocrine treatment.

    Urothelial carcinoma (UC) remains a significant health problem affecting an estimated 68,810 people in 2008 alone in the US. The majority of patients with metastatic disease develop disease recurrence, and long-term survival rates are poor. There is no standard of care for the treatment of patients with UC after the failure of cisplatin-based regimens in the first-line setting. Efforts to improve second-line treatment have led to the evaluation of single agents such as vinflunine and pemetrexed, and multidrug combinations with cytotoxic and targeted agents, including trastuzumab and bevacizumab. The authors reviewed the activity of several single agents and combination regimens in patients with UC. Emerging strategies for the measurement of response in clinical trials were also outlined.

    In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.

    Differentiated thyroid cancer is the most common endocrine malignancy, and its incidence has been rising rapidly over the past 10 years. Although most patients with this disease have an excellent prognosis, a subset develops a more aggressive disease phenotype refractory to conventional therapies. Until recently, there was no effective therapy for these patients. With increasing knowledge of the molecular pathogenesis of thyroid cancer, novel targeted therapies are being developed for this group of patients. Sorafenib and lenvatinib, small-molecule multikinase inhibitors, were approved for the treatment of progressive, symptomatic, radioactive iodine refractory, advanced differentiated thyroid cancer in 2013 and 2015, respectively. This represents a major innovation in the therapy of patients with advanced thyroid cancer. However, these therapies still have many limitations and further research needs to be pursued with the ultimate goal of providing safe and effective personalized therapy for patients with advanced thyroid cancer.

    Pancreatic cancer is relatively insensitive to conventional chemotherapy. Therefore, novel agents targeting dysregulated pathways (MAPK/ERK, EGFR, TGF-β, HEDGEHOG, NOTCH, IGF, PARP, PI3K/AKT, RAS, and Src) are being explored in clinical trials as monotherapy or in combination with cytotoxic chemotherapy. This review summarizes the most recent advances with the targeted therapies in the treatment of patients with advanced pancreatic cancer. PMID:26369833

    Cancer stem cells have been defined as cells within a tumor that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumor. Experimental evidence showed that these highly tumorigenic cells might be responsible for initiation and progression of cancer into invasive and metastatic disease. Eradicating prostate cancer stem cells, the root of the problem, has been considered as a promising target in prostate cancer treatment to improve the prognosis for patients with advanced stages of the disease.

    The diagnosis for locally advanced pancreatic cancer is based on high-quality cross-sectional imaging, which shows tumor invasion into the celiac/superior mesenteric arteries and/or superior mesenteric/portal venous system that is not reconstructable. The optimal management of these patients is evolving quickly with the advent of newer chemotherapeutics, radiation, and nonthermal ablation modalities. This article presents the current status of initial chemotherapy, surgical therapy, ablative therapy, and radiation therapy for patients with nonmetastatic locally advanced unresectable pancreatic cancer. Surgical resection offers the best chance of long-term disease control and the only chance for cure for patients with nonmetastatic exocrine pancreatic cancer.

    There are currently three major approaches to T cell-based cancer immunotherapy, namely, active vaccination, adoptive cell transfer therapy and immune checkpoint blockade. Recently, this latter approach has demonstrated remarkable clinical benefits, putting cancer immunotherapy under the spotlight. Better understanding of the dynamics of anti-tumor immune responses (the "Cancer-Immunity Cycle") is crucial for the further development of this form of treatment. Tumors employ multiple strategies to escape from anti-tumor immunity, some of which result from the selection of cancer cells with immunosuppressive activity by the process of cancer immunoediting. Apart from this selective process, anti-tumor immune responses can also be inhibited in multiple different ways which vary from patient to patient. This implies that cancer immunotherapy must be personalized to (1) identify the rate-limiting steps in any given patient, (2) identify and combine strategies to overcome these hurdles, and (3) proceed with the next round of the "Cancer-Immunity Cycle". Cancer cells have genetic alterations which can provide the immune system with targets by which to recognize and eradicate the tumor. Mutated proteins expressed exclusively in cancer cells and recognizable by the immune system are known as neoantigens. The development of next-generation sequencing technology has made it possible to determine the genetic landscape of human cancer and facilitated the utilization of genomic information to identify such candidate neoantigens in individual cancers. Future immunotherapies will need to be personalized in terms of the identification of both patient-specific immunosuppressive mechanisms and target neoantigens.

    This paper explores feature reduction properties of independent component analysis (ICA) on breast cancer decision support system. Wisconsin diagnostic breast cancer (WDBC) dataset is reduced to one-dimensional feature vector computing an independent component (IC). The original data with 30 features and reduced one feature (IC) are used to evaluate diagnostic accuracy of the classifiers such as k-nearest neighbor (k-NN), artificial neural network (ANN), radial basis function neural network (RBFNN), and support vector machine (SVM). The comparison of the proposed classification using the IC with original feature set is also tested on different validation (5/10-fold cross-validations) and partitioning (20%-40%) methods. These classifiers are evaluated how to effectively categorize tumors as benign and malignant in terms of specificity, sensitivity, accuracy, F-score, Youden's index, discriminant power, and the receiver operating characteristic (ROC) curve with its criterion values including area under curve (AUC) and 95% confidential interval (CI). This represents an improvement in diagnostic decision support system, while reducing computational complexity.

    Pancreatic carcinoma is a common cancer of the digestive system with a poor prognosis. It is characterized by insidious onset, rapid progression, a high degree of malignancy and early metastasis. At present, radical surgery is considered the only curative option for treatment, however, the majority of patients with pancreatic cancer are diagnosed too late to undergo surgery. The sensitivity of pancreatic cancer to chemotherapy or radiotherapy is also poor. As a result, there is no standard treatment for patients with advanced pancreatic cancer. Cryoablation is generally considered to be an effective palliative treatment for pancreatic cancer. It has the advantages of minimal invasion and improved targeting, and is potentially safe with less pain to the patients. It is especially suitable in patients with unresectable pancreatic cancer. However, our initial findings suggest that cryotherapy combined with 125-iodine seed implantation, immunotherapy or various other treatments for advanced pancreatic cancer can improve survival in patients with unresectable or metastatic pancreatic cancer. Although these findings require further in-depth study, the initial results are encouraging. This paper reviews the safety and efficacy of cryoablation, including combined approaches, in the treatment of pancreatic cancer. PMID:26811625

  1. Photodynamic Cancer Therapy - Recent Advances

    SciTech Connect

    Abrahamse, Heidi

    2011-09-22

    The basic principle of the photodynamic effect was discovered over a hundred years ago leading to the pioneering work on PDT in Europe. It was only during the 1980s, however, when 'photoradiation therapy' was investigated as a possible treatment modality for cancer. Photodynamic therapy (PDT) is a photochemotherapeutic process which requires the use of a photosensitizer (PS) that, upon entry into a cancer cell is targeted by laser irradiation to initiate a series of events that contribute to cell death. PSs are light-sensitive dyes activated by a light source at a specific wavelength and can be classified as first or second generation PSs based on its origin and synthetic pathway. The principle of PS activation lies in a photochemical reaction resulting from excitation of the PS producing singlet oxygen which in turn reacts and damages cell organelles and biomolecules required for cell function and ultimately leading to cell destruction. Several first and second generation PSs have been studied in several different cancer types in the quest to optimize treatment. PSs including haematoporphyrin derivative (HpD), aminolevulinic acid (ALA), chlorins, bacteriochlorins, phthalocyanines, naphthalocyanines, pheophorbiedes and purpurins all require selective uptake and retention by cancer cells prior to activation by a light source and subsequent cell death induction. Photodynamic diagnosis (PDD) is based on the fluorescence effect exhibited by PSs upon irradiation and is often used concurrently with PDT to detect and locate tumours. Both laser and light emitting diodes (LED) have been used for PDT depending on the location of the tumour. Internal cancers more often require the use of laser light delivery using fibre optics as delivery system while external PDT often make use of LEDs. Normal cells have a lower uptake of the PS in comparison to tumour cells, however the acute cytotoxic effect of the compound on the recovery rate of normal cells is not known. Subcellular

    There has been progress over the last decade in addressing three questions: Are there cancer-associated antigens that could be targets for immunotherapy? Can the human immune system recognize cancer-associated antigens? Can an anti-cancer immune response affect cancer cells and lead to increased survival? Results from animal model studies have been interpreted by optimists as encouraging, and by pessimists as being irrelevant to human cancer. Earlier studies on "cancer vaccines" utilized heterogeneous cell extracts of cell components. Monoclonal antibodies have enabled identification of relevant cancer-associated antigens or epitopes, such as the ganglioside GM2, the carbohydrates TF and STn, and the peptide sequences of MUC-1. In parallel with research on immune adjuvants and measures designed to inhibit suppressor activity, these epitopes are being tested for their potential in the immunotherapy of solid tumors. It is clear that some of these cancer-associated epitopes are immunogenic in humans. Mixed responses may relate to cancer heterogeneity and may indicate the importance of multi-epitopic vaccines. Responses are encouraging, but are they relevant? Prolonged disease stability challenges us to re-think the goals of cancer therapy. Recent advances in the knowledge of the effect of cytokines on tumor antigen expression and the regulation of the immune response, coupled with advances in active specific immunotherapy, provide hope that biomodulation may become an important part of the therapy of solid tumors in the next century.

    Background: Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV) have been successful interventions for prevention of invasive cervical cancer (ICC). Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical screening in these countries. Therefore, ICC is usually diagnosed in advanced stages with poor prognosis in these countries. We performed a priority setting exercise and suggested priorities for prevention of ICC in this setting. Methods: We invited experts and researchers to a workshop and asked them to list important suggestions for ICC prevention in Iran. After merging similar items and removing the duplicates, we asked the experts to rank the list of suggested items. We used a strategy grid and Go-zone analysis to determine final list of priorities for ICC prevention in Iran. Results: From 26 final items suggested as priorities for prevention of ICC, the most important priorities were developing national guidelines for cervical screening and quality control protocol for patient follow-up and management of precancerous lesions. In addition, we emphasized considering insurance coverage for cervical screening, public awareness, and research priorities, and establishment of a cervical screening registry. Conclusion: A comprehensive approach and implementation of organized cervical screening program is necessary for prevention of ICC in Iran and other low incidence Muslim countries. Because of high cost for vaccination and low incidence of cervical cancer, we do not recommend HPV vaccination for the time being in Iran. PMID:27239863

    In the past 20 years, cancer therapeutics has undergone a paradigm shift away from the traditional cytotoxic drugs towards the targeting of proteins intimately involved in driving the cancer phenotype. The poster child for this alternative approach to the treatment of cancer is imatinib, a small-molecule kinase inhibitor designed to target chronic myeloid leukaemia driven by the BCR-ABL translocation in a defined patient population. The improvement in survival achieved by treatment of this patient cohort with imatinib is impressive. Thus, the aim is to provide efficacy but with low toxicity. The role of the medicinal chemist in oncology drug discovery is now closely aligned with the role in most other therapeutic areas with high-throughput and/or fragment-based screening, structure-based design, selectivity, pharmacokinetic optimisation and pharmacodynamic biomarker modulation, all playing a familiar part in the process. In this chapter, we selected four areas in which compounds are either approved drugs or in clinical trials. These are chaperone inhibitors, kinase inhibitors, histone deacetylase inhibitors and inhibitors of protein-protein interactions. Even within these areas, we have been selective, particularly for kinase inhibitors, and our aim has been to exemplify newer approaches and novel aspects of medicinal chemistry.

    Thyroid cancer is the most common endocrine tumor. Thyroidectomy, radioactive iodine, and TSH suppression represent the standard treatment for differentiated thyroid cancer. Since chemotherapy has been shown to be unsuccessful in case of advanced thyroid carcinomas, the research for new therapies is fundamental. In this paper, we reviewed the recent literature reports (pubmed, medline, EMBASE database, and abstracts published in meeting proceedings) on new treatments in advanced nonmedullary and medullary thyroid carcinomas. Studies of many tyrosine kinase inhibitors as well as antiangiogenic inhibitors suggest that patients with thyroid cancer could have an advantage with new target therapy. We summarized both the results obtained and the toxic effects associated with these treatments reported in clinical trials. Reported data in this paper are encouraging, but further trials are necessary to obtain a more effective result in thyroid carcinoma treatment. PMID:23133451

    Lessons learned over the past decade and a half of combat casualty management has brought about numerous advances in trauma anesthesia practice. In the post-Vietnam era, deployable anesthesia equipment centered on the capability to provide a balanced anesthetic technique, utilizing a combination of volatile gas and intravenous anesthetic adjuncts. The evolution of the modern battlefield has forced anesthesia providers across the military to adapt to mission requirements that often dictate a surgical capability that is more rapidly mobile and less reliant on logistical support. Institutional medical equipment development has focused on fielding a lighter, more mobile volatile gas delivery method. Despite numerous advances in anesthetic gas delivery, many veteran anesthesia providers have come to recognize the value of alternative anesthetic techniques in the deployed setting. One of the most appealing advances in combat anesthesia practice is the emergence of total intravenous anesthetics (TIVA) for trauma management and resuscitation. Although there have been numerous developments in anesthetic equipment for use in the deployed setting, TIVA has many advantages over volatile gas administration. Future research, development, and education should focus on TIVA and the ability to provide this as an alternative safe anesthetic for patients in austere environments. It is imperative to retain the lessons we have learned in order to adapt more effectively in future conflicts. This accumulation of knowledge must inform future innovative solutions to the challenges of casualty management in a deployed setting.

    Lung cancer is the most commonly diagnosed cancer as well as the leading cause of cancer-related deaths worldwide. To date, surgery is the first choice treatment, but most clinically diagnosed cases are inoperable. While chemotherapy and/or radiotherapy are the next considered options for such cases, these treatment modalities have adverse effects and are sometimes lethal to patients. Thus, new effective strategies with minimal side effects are urgently needed. Cancer immunotherapy provides either active or passive immunity to target tumors. Multiple immunotherapy agents have been proposed and tested for potential therapeutic benefit against lung cancer, and some pose fewer side effects as compared to conventional chemotherapy and radiotherapy. In this article, we discuss studies focusing on interactions between lung cancer and the immune system, and we place an emphasis on outcome evidence in order to create a knowledge base well-grounded in clinical reality. Overall, this review highlights the need for new lung cancer treatment options, with much ground to be paved for future advances in the field. We believe that immunotherapy agents alone or with other forms of treatment can be recognized as next modality of lung cancer treatment. PMID:27168951

    When radiation therapy is used for palliation of obstruction in patients with advanced esophageal carcinoma, an improvement in dysphagia can be expected in approximately 50% of patients. Major objective responses have rarely been quantitied but, in one study, were seen in 33% patients. Recurrence of dysphagia is usually seen within 2-6 months of treatment. Radiation toxicities and complications, even when used with palliative intent, can be substantial and include esophagitis, tracheoesophageal or esophageal-aortic fistula, mediastinitis, hemorrhage, pneumonitis, and myelosuppression.

    The majority of advanced breast cancers have genetic alterations that are potentially targetable with drugs. Through initiatives such as The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC), data can be mined to provide context for next-generation sequencing (NGS) results in the landscape of advanced breast cancer. Therapies for targets other than estrogen receptor alpha (ER) and HER2, such as cyclin-dependent kinases CDK4 and CDK6, were recently approved based on efficacy in patient subpopulations, but no predictive biomarkers have been found, leaving clinicians to continue a trial-and-error approach with each patient. Next-generation sequencing identifies potentially actionable alterations in genes thought to be drivers in the cancerous process including phosphatidylinositol 3-kinase (PI3K), AKT, fibroblast growth factor receptors (FGFRs), and mutant HER2. Epigenetically directed and immunologic therapies have also shown promise for the treatment of breast cancer via histone deacetylases (HDAC) 1 and 3, programmed T cell death 1 (PD-1), and programmed T cell death ligand 1 (PD-L1). Identifying biomarkers to predict primary resistance in breast cancer will ultimately affect clinical decisions regarding adjuvant therapy in the first-line setting. However, the bulk of medical decision-making is currently made in the secondary resistance setting. Herein, we review the clinical potential of PI3K, AKT, FGFRs, mutant HER2, HDAC1/3, PD-1, and PD-L1 as therapeutic targets in breast cancer, focusing on the rationale for therapeutic development and the status of clinical testing.

    Global trends in public health nursing (PHN) suggest the value of community-based social research. However, it is not always clear how social research relationships may be of benefit to PHN or how such skills can best be learned and applied. To advance this understanding, we present a qualitative analysis of the development of social research relationships in PHN. Using a background literature review as a foundation, our qualitative mixed method strategy involved a comparative case-study analysis based on the authors' participant observation in two distinct postnatal group settings. Our findings suggest that participant observation facilitates the advancement of social research relationships through practitioner-research management of role conflict. Reflexivity and reciprocity is an emergent relational process, which relies upon a de-professionalization of the traditional PHN role. Conversely, social research relationships help build PHN capacity for family health needs assessment. Thus, we contend that the application of participant observation enables the development of social research relationships, which advance the practice of PHN in postnatal support settings.

    Despite a decrease in incidence over past decades, gastric cancer remains a major global health problem. In the more recent period, survival has shown only minor improvement, despite significant advances in diagnostic techniques, surgical and chemotherapeutic approaches, the development of novel therapeutic agents and treatment by multidisciplinary teams. Because multiple genetic mutations, epigenetic alterations, and aberrant molecular signalling pathways are involved in the development of gastric cancers, recent research has attempted to determine the molecular heterogeneity responsible for the processes of carcinogenesis, spread and metastasis. Currently, some novel agents targeting a part of these dysfunctional molecular signalling pathways have already been integrated into the standard treatment of gastric cancer, whereas others remain in phases of investigation within clinical trials. It is essential to identify the unique molecular patterns of tumours and specific biomarkers to develop treatments targeted to the individual tumour behaviour. This review analyses the global impact of gastric cancer, as well as the role of Helicobacter pylori infection and the efficacy of bacterial eradication in preventing gastric cancer development. Furthermore, the paper discusses the currently available targeted treatments and future directions of research using promising novel classes of molecular agents for advanced tumours. PMID:27570417

    Cancer is both highly feared and highly newsworthy, and there is a robust body of research documenting the content and effects of cancer news coverage on health behaviors and policy. Recent years have witnessed ongoing, transformative shifts in American journalism alongside rapid advances in communication technology and the public information environment. These changes create a pressing need to consider a new set of research questions, sampling strategies, measurement techniques, and theories of media effects to ensure continued relevance and adaptation of communication research to address critical cancer control concerns. This paper begins by briefly reviewing what we know about the role of cancer news in shaping cancer-related beliefs, attitudes, behaviors, and policies. We then outline challenges and opportunities, both theoretical and methodological, posed by the rapidly changing news media environment and the nature of audience engagement. We organize our discussion around three major shifts associated with the emerging news media environment as it relates to health communication: 1) speed and dynamism of news diffusion, 2) increased narrowcasting of media content for specialized audiences, and 3) broadened participation in shaping media content. In so doing, we articulate a set of questions for future theory and research, in an effort to catalyze innovative communication scholarship to improve cancer prevention and control.

    Individuals with advanced oropharyngeal cancer often experience dysphagia as a result of their illness and its treatment. Research consistently demonstrates that dysphagia and difficulty with oral intake have many implications, including a negative impact on quality of life. Nurses are in a key position to provide support and initiate appropriate interventions for individuals with dysphagia. Using the Human Response to Illness model (Mitchell et al, 1991) as an organising framework, this paper presents a critical review of the empirical literature regarding dysphagia in individuals with advanced oropharyngeal cancer that will: i) provide the reader with a comprehensive understanding of dysphagia; ii) identify current gaps in our knowledge; and iii) establish the foundation for appropriate evidence-based interventions to optimise functioning and quality of life in this patient population.

    The identification of molecular subtypes of non-small-cell lung cancer has transformed the clinical management of this disease. This is best exemplified by the clinical success of targeting the EGFR or ALK with tyrosine kinase inhibitors in the front-line setting. Our ability to further improve patient outcomes with biomarker-based targeted therapies will depend on a more comprehensive genetic platform that can rationally interrogate the cancer genome of an individual patient. Novel technologies, including multiplex genotyping and next-generation sequencing are rapidly evolving and will soon challenge the oncologist with a wealth of genetic information for each patient. Although there are many barriers to overcome, the integration of these genetic platforms into clinical care has the potential to transform the management of lung cancer through improved molecular categorization, patient stratification, and drug development, thereby, improving clinical outcomes through personalized lung cancer medicine.

    2013-01-01

    The “clonal evolution” model of cancer emerged and “evolved” amid ongoing advances in technology, especially in recent years during which next generation sequencing instruments have provided ever higher resolution pictures of the genetic changes in cancer cells and heterogeneity in tumors. It has become increasingly clear that clonal evolution is not a single sequential process, but instead frequently involves simultaneous evolution of multiple subclones that co-exist because they are of similar fitness or are spatially separated. Co-evolution of subclones also occurs when they complement each other’s survival advantages. Recent studies have also shown that clonal evolution is highly heterogeneous: different individual tumors of the same type may undergo very different paths of clonal evolution. New methodological advancements, including deep digital sequencing of a mixed tumor population, single cell sequencing, and the development of more sophisticated computational tools, will continue to shape and reshape the models of clonal evolution. In turn, these will provide both an improved framework for the understanding of cancer progression and a guide for treatment strategies aimed at the elimination of all, rather than just some, of the cancer cells within a patient.

  1. Surgery for advanced epithelial ovarian cancer.

    Hacker, Neville F; Rao, Archana

    2016-10-20

    Cytoreductive surgery for patients with advanced epithelial ovarian cancer has been practised since the pioneering work of Tom Griffiths in 1975. Further research has demonstrated the prognostic significance of the extent of metastatic disease pre-operatively, and of complete cytoreduction post-operatively. Patients with advanced epithelial ovarian cancer should be referred to high volume cancer units, and managed by multidisciplinary teams. The role of thoracoscopy and resection of intrathoracic disease is presently investigational. In recent years, there has been increasing use of neoadjuvant chemotherapy and interval cytoreductive surgery in patients with poor performance status, which is usually due to large volume ascites and/or large pleural effusions. Neoadjuvant chemotherapy reduces the post-operative morbidity, but if the tumour responds well to the chemotherapy, the inflammatory response makes the surgery more difficult. Post-operative morbidity is generally tolerable, but increases in older patients, and in those having multiple, aggressive surgical procedures, such as bowel resection or diaphragmatic stripping. Primary cytoreductive surgery should be regarded as the gold standard for most patients until a test is developed which would allow the prediction of platinum resistance pre-operatively.

    2012-01-01

    Personalized medicine aims to deliver the right drug to a right patient at the right time. It offers unique opportunities to integrate new technologies and concepts to disease prognosis, diagnosis and therapeutics. While selective personalized therapies are conceptually impressive, the majority of cancer therapies have dismal outcome. Such therapeutic failure could result from no response, drug resistance, disease relapse or severe side effect from improper drug delivery. Nanomedicine, the application of nanotechnology in medicine, has a potential to advance the identification of diagnostic and prognostic biomarkers and the delivery of right drug to disease sites. Epigenetic aberrations dynamically contribute to cancer pathogenesis. Given the individualized traits of epigenetic biomarkers, epigenetic considerations would significantly refine personalized nanomedicine. This review aims to dissect the interface of personalized medicine with nanomedicine and epigenetics. I will outline the progress and highlight challenges and areas that can be further explored perfecting the personalized health care. PMID:22921595

    A retrospective study of 75 patients with advanced inoperable gastric cancers, referred to the National Cancer Center Hospital between 1962 and 1982, was performed. According to the Borrmann classification based on X ray findings, Type 1 was found in 3 patients, Type 2 in 5, Type 3 in 40, and Type 4 in 15. Twelve patients could not be classified. The histological type was papillary adenocarcinoma in 7 patients, tubular adenocarcinoma in 23, mucinous carcinoma in 6, poorly differentiated adenocarcinoma in 14, signet ring cell carcinoma in 12 and others in 13. The site of remote metastasis in 19 patients was Virchow's lymph node in 8 patients, Douglas pouch in 3, liver and lung in 2 each and others in 4. All patients were treated by a either telecobalt 60 unit or a linear accelerator using 6 Mv photon and the total dose to primary lesion was 4000 cGy in 5 weeks to 7000 cGy in 8-9 weeks. Complete response (CR) was achieved in 6 patients or 8.0%, partial response (PR) in 46 or 61.3%, and no change (NC) in 23 or 30.7%. The response rate based on the sum of CR and PR was about 70%. The 50% survival period in months was 26.5, 7.3, and 3.2, respectively for patients with CR, PR, and NC. For the response of advanced gastric cancer to chemotherapy in the National Cancer Center Hospital, the combined use of UFT and Mitomycin C gave the highest rate, 46%. As for as local response is concerned, the response rate to radiation was 70%, a better result than that of chemotherapy alone.

    Radiation therapy (RT) as part of multidisciplinary oncologic care has been marked by profound advancements over the past decades. As part of multimodality therapy for esophageal cancer (EC), a prime goal of RT is to minimize not only treatment toxicities, but also postoperative complications and hospitalizations. Herein, discussion commences with the historical approaches to treating EC, including seminal trials supporting multimodality therapy. Subsequently, the impact of RT techniques, including three-dimensional conformal RT, intensity-modulated RT, and proton beam therapy, is examined through available data. We further discuss existing data and the potential for further development in the future, with an appraisal of the future outlook of technological advancements of RT for EC. PMID:27775643

    2017-04-01

    The treatment of locally advanced esophageal cancer is controversial. For patients who are candidates for surgical resection, multiple prospective clinical trials have demonstrated the advantages of neoadjuvant chemoradiation. For patients who are medically inoperable, definitive chemoradiation is an alternative approach with survival rates comparable to trimodality therapy. Although trials of dose escalation are ongoing, the standard radiation dose remains 50.4 Gy. Modern radiotherapy techniques such as image-guided radiation therapy with motion management and intensity-modulated radiation therapy are strongly encouraged with a planning objective to maximize conformity to the intended target volume while reducing dose delivered to uninvolved normal tissues.

  6. Advanced level set segmentation of the right atrium in MR

    Atrial fibrillation is a common heart arrhythmia, and can be effectively treated with ablation. Ablation planning requires 3D models of the patient's left atrium (LA) and/or right atrium (RA), therefore an automatic segmentation procedure to retrieve these models is desirable. In this study, we investigate the use of advanced level set segmentation approaches to automatically segment RA in magnetic resonance angiographic (MRA) volume images. Low contrast to noise ratio makes the boundary between the RA and the nearby structures nearly indistinguishable. Therefore, pure data driven segmentation approaches such as watershed and ChanVese methods are bound to fail. Incorporating training shapes through PCA modeling to constrain the segmentation is one popular solution, and is also used in our segmentation framework. The shape parameters from PCA are optimized with a global histogram based energy model. However, since the shape parameters span a much smaller space, it can not capture fine details of the shape. Therefore, we employ a second refinement step after the shape based segmentation stage, which follows closely the recent work of localized appearance model based techniques. The local appearance model is established through a robust point tracking mechanism and is learned through landmarks embedded on the surface of training shapes. The key contribution of our work is the combination of a statistical shape prior and a localized appearance prior for level set segmentation of the right atrium from MRA. We test this two step segmentation framework on porcine RA to verify the algorithm.

    2015-01-01

    Esophageal cancer represents one of the most aggressive digestive tumors, with a survival rate at 5 years of only 10%. Globally, during the last three decades, there has been an increasing incidence of the esophageal cancer, approx. 400,000 new esophageal cancers being currently diagnosed annually. This represents the eighth leading cause of cancer incidence and the sixth leading cause of cancer death overall. Taking into account the population’s global aging and thus, the increase in the number of patients who will not bear surgery, PCT and radiation, or the fact that they do not want it especially because of deficiencies and associated pathology, the endoscopic ablative techniques with palliation purposes represent the alternative. If we refer to the Western Europe countries and North America, we notice an increase of esophageal adenocarcinoma rate versus squamous cancer. As for the Asian region, referring in particular to China and Japan, 9 out of 10 esophageal cancers are squamous cell carcinomas. For at least half of the patients with EC (esophageal cancer) there is no hope of healing because of the advanced regional malignant invasion (T3-4, N+, M+) with no chemo and radiotherapy response, poor preoperative patients’ conditions or systemic metastasis. The low life expectancy does not justify the risky medical procedures, the goal of the therapy consisting in the improvement of the quality of life by eliminating dysphagia (reestablishing oral feeding) which represents the most common complication of EC, the respiratory tract complication caused by eso-tracheal fistulas or by eliminating chest pain. To treat dysphagia, which is the main target of palliation, combined methods like endoscopic, chemo and radio-therapy, can be used, each one with indications, benefits and risks.

    To identify research priorities and appropriate resources and to establish the infrastructure required to address the emergency care of patients with cancer, the National Institutes of Health's National Cancer Institute and the Office of Emergency Care Research sponsored a one-day workshop, "Cancer and Emergency Medicine: Setting the Research Agenda," in March 2015 in Bethesda, MD. Participants included leading researchers and clinicians in the fields of oncology, emergency medicine, and palliative care, and representatives from the National Institutes of Health. Attendees were charged with identifying research opportunities and priorities to advance the understanding of the emergency care of cancer patients. Recommendations were made in 4 areas: the collection of epidemiologic data, care of the patient with febrile neutropenia, acute events such as dyspnea, and palliative care in the emergency department setting.

    A state registered dietitian assessed the voluntary dietary intake of 13 advanced cancer inpatients on one ward of St. Christopher's Hospice for five consecutive days. There were 11 females, two males; median age 74 years (range 56 to 83). Two patients died on the fourth day of the study. A partially individualised weighed technique was used. Standard sized scoops and spoons were used to serve the food in small, medium or large standard portions (depending on appetite) and were weighed as served. Individual plate waste (by weight) was subtracted to give estimated individual intake. Foods provided by visitors was not included. The median and range of individual mean daily intakes (estimated) were: energy 5760 (938-8945) kJ, 1376 (224-2137) kcal; protein 44 (11-86) g; fat 52 (9-93) g; carbohydrate 169 (21-194) g; calcium 748 (268-1457) mg; iron 4.8 (0.5-21.0) mg; dietary fibre 5.0 (0.5-21.0) g. Compared to recommended amounts, energy, iron and dietary fibre intakes were low; calcium intake was high. Nutritional status may affect prognosis and/or subjective well-being in advanced cancer. The value of nutritional supplementation and the role of appetite stimulants in improving nutritional status needs investigation.

    The National Cancer Institute (NCI) Symptom Management and Health-Related Quality of Life Steering Committee convened four working groups to recommend core sets of patient-reported outcomes to be routinely incorporated in clinical trials. The Prostate Cancer Working Group included physicians, researchers, and a patient advocate. The group's process included 1) a systematic literature review to determine the prevalence and severity of symptoms, 2) a multistakeholder meeting sponsored by the NCI to review the evidence and build consensus, and 3) a postmeeting expert panel synthesis of findings to finalize recommendations. Five domains were recommended for localized prostate cancer: urinary incontinence, urinary obstruction and irritation, bowel-related symptoms, sexual dysfunction, and hormonal symptoms. Four domains were recommended for advanced prostate cancer: pain, fatigue, mental well-being, and physical well-being. Additional domains for consideration include decisional regret, satisfaction with care, and anxiety related to prostate cancer. These recommendations have been endorsed by the NCI for implementation.

    Background A phase 2 study showed that progression-free survival was longer with palbociclib plus letrozole than with letrozole alone in the initial treatment of postmenopausal women with estrogen-receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer. We performed a phase 3 study that was designed to confirm and expand the efficacy and safety data for palbociclib plus letrozole for this indication. Methods In this double-blind study, we randomly assigned, in a 2:1 ratio, 666 postmenopausal women with ER-positive, HER2-negative breast cancer, who had not had prior treatment for advanced disease, to receive palbociclib plus letrozole or placebo plus letrozole. The primary end point was progression-free survival, as assessed by the investigators; secondary end points were overall survival, objective response, clinical benefit response, patient-reported outcomes, pharmacokinetic effects, and safety. Results The median progression-free survival was 24.8 months (95% confidence interval [CI], 22.1 to not estimable) in the palbociclib-letrozole group, as compared with 14.5 months (95% CI, 12.9 to 17.1) in the placebo-letrozole group (hazard ratio for disease progression or death, 0.58; 95% CI, 0.46 to 0.72; P<0.001). The most common grade 3 or 4 adverse events were neutropenia (occurring in 66.4% of the patients in the palbociclib-letrozole group vs. 1.4% in the placebo-letrozole group), leukopenia (24.8% vs. 0%), anemia (5.4% vs. 1.8%), and fatigue (1.8% vs. 0.5%). Febrile neutropenia was reported in 1.8% of patients in the palbociclib-letrozole group and in none of the patients in the placebo-letrozole group. Permanent discontinuation of any study treatment as a result of adverse events occurred in 43 patients (9.7%) in the palbociclib-letrozole group and in 13 patients (5.9%) in the placebo-letrozole group.

    Breast cancer may recur through 15 years and beyond after diagnosis; thus, breast cancer patients require long-term follow-up after adjuvant treatment to detect recurrent disease. History taking, physical examination, and regular mammography are still the foundation of appropriate breast cancer follow-up in the adjuvant setting. Clearly, breast MRI has a role in certain high-risk patients, but in moderate-risk patients, the decision to use MRI must be based on the complexity of the clinical scenario. Other routine imaging studies (CT, positron emission tomography, and bone scans) and laboratory testing--including tumor marker assessments--in asymptomatic patients have not demonstrated an improvement in survival, quality of life, toxicity, or cost-effectiveness. Survivorship issues are also an inherent part of breast cancer follow-up; physicians should make every effort to address supportive care issues unique to breast cancer survivors including hot flashes, bone health, neuropathy, and risk-reduction strategies.

    Fatigue is a common advanced cancer symptom. Clinical features are not well known. The authors surveyed consecutive patients admitted to a palliative medicine program to identify clinical correlates of fatigue. Data collected included age, sex, performance status, primary site, prior chemotherapy/radiation therapy, and blood transfusions. Visual analogue scales assessed fatigue, quality of life, and ability to perform daily activities. Weight change was estimated. Laboratory results including lactate dehydrogenase and hemoglobin were recorded. Fatigue severity was associated with brain metastases, poor performance status, poor quality of life, and reduced ability to perform activities. Prior radiation therapy was associated with less severe fatigue. Age, sex, and hemoglobin level were not associated with fatigue. Fatigue was universal on referral. Brain metastases and poor quality of life independently predicted severity. Hemoglobin level did not predict fatigue. Further studies are necessary to define the clinical features and relationships of fatigue.

    Lysine methylation plays a vital role in histone modification. Deregulations of lysine methyltransferases and demethylases have been frequently observed in human cancers. The SET and MYND domain containing protein 3 (SMYD3) is a novel histone lysine methyltransferase and it functions by regulating chromatin during the development of myocardial and skeletal muscle. It has been recently unveiled to play significant roles in human cancer genesis and progression via regulating various key cancer-associated genes and pathways and promoting cell proliferation and migration. Upregulation of SMYD3 expression is present in multiple cancer types, suggesting it as a potential prognostic marker. Herein the structure, substrates and targets of SMYD3, and its effects on initiation, invasion and metastasis of diverse tumors (e.g., esophageal squamous cell carcinoma, gastric cancer, hepatocellular carcinoma, cholangiocarcinoma, breast cancer, prostate cancer, and leukemia) are systematically reviewed, providing clues for the development of novel SMYD3-specific personalized anti-cancer therapy. SMYD3 inhibitors (e.g., BCI-121 and novobiocin) could hopefully fight against tumors with efficacy. PMID:28123630

    Immunotherapy is heralded as one of the most important advances in oncology. Until recently, only limited immunotherapeutic options were available in selected immunogenic cancers like melanoma and renal cell carcinomas. Nowadays, there is an improved understanding that anti-tumor immunity is controlled by a delicate balance in the tumor microenvironment between immune stimulatory and immune inhibitory pathways. Either by blocking the inhibitory pathways or stimulating the activating pathways that regulate cytotoxic lymphocytes, anti-tumor immunity can be enhanced leading to durable anti-tumor responses. Drugs which block the immune regulatory checkpoints namely the PD-1/PDL1 and CTLA 4 pathway have shown tremendous promise in a wide spectrum of solid and hematological malignancies, significantly improving overall survival in newly diagnosed and heavily pretreated patients alike. Hence there is renewed enthusiasm in the field of immune oncology with current research focused on augmenting responses to checkpoint inhibitors by combination therapy as well as studies looking at other immune modulators and adoptive T cell therapy. In this article, we highlight the key clinical advances and concepts in immunotherapy with particular emphasis on checkpoint inhibition as well as the future direction in this field. PMID:27886124

    Background There is evidence regarding the usefulness of psychosocial intervention to improve health related quality of life (HRQOL) in adult cancer patients. The aim of this report is to describe an integrated approach and to evaluate its feasibility in routine clinical practice in 98 advanced colorectal cancer (ACC) patients during chronomodulated chemotherapy. Methods A prospective non-randomised design was developed and applied in a cancer out-patient setting. The intervention consisted of an integrated approach, whereby the psycho-oncologist had an active role in the health care team with the physician and routinely included psychological understanding in the medical treatment program. The psychological evaluation assessed: a) adaptation, awareness, psychopathological disorders through a psychodynamic interview; b) anxiety and depression using the HAD scale; c) subjective perception of care quality through a structured interview and d) HRQOL evaluation assessment with the EORTC QLQ C30. Outcomes data were collected before and after 18 weeks of chemotherapy. Results After 18 weeks of chemotherapy a significant improvement of adaptation and awareness was observed. The HADs results showed a significant decrease in anxiety when compared to pre-treatment. The structured interview showed a significant increase of patients who positively experienced the impact of medical treatment on HRQOL, anxiety, depression, interpersonal relationships, free-time and who positively experienced the care quality. Indeed, a majority of patients positively experienced the team relationship modality during the whole treatment. All scales on the EORTC questionnaire remained unchanged during the entire treatment. Conclusion Our results suggest that it is feasible to carry out an integrated approach during chemotherapy. These results seem to support the integrated approach as a tool in aiding advanced colorectal cancer patients' ability to cope with their diagnosis and treatment although

    Kidney cancers' natural history has radically changed in the past few years, due to the development of novel targeted agents. Despite these improvements, several unanswered questions still remain on the table, regarding the best first-line treatment, the ideal sequence of treatments, the management of specific subgroups of patients (e.g., elderly patients or those with comorbidities) and the relevance of prognostic factors, among many others. To foster discussions among clinicians and investigators working in this field, and to exchange different viewpoints concerning the newest advances in kidney cancer pathogenesis and treatment, the 3rd Pavia International Symposium on Advanced Kidney cancer was held in Pavia (Italy) between 30 June and 1 July 2011. The aim of this report is to summarize the most significant advances in the different disciplines applied to advanced kidney cancer, which were presented and discussed during the meeting, and how these advances will be changing the perspective of patients with this disease.

    Lung cancer is the most common cancer worldwide and the fifth most common cause of death globally. Its incidence continues to increase, especially within low- and middle-income countries (LMICs), which have limited capacity to address the growing need for treatment. The standard of care for lung cancer treatment often involves radiation therapy (RT), which plays an important therapeutic role in curative-intent treatment of early-stage to locally advanced disease, as well as in palliation. The infrastructure, equipment, and human resources required for RT may be limited in LMICs. However, this narrative review discusses the scope of the problem of lung cancer in LMICs, the role of RT technologies in lung cancer treatment, and RT capacity in developing countries. Strategies are presented for maximizing the availability and impact of RT in settings with minimal resource availability, and areas for potential future innovation are identified. Priorities for LMICs involve increasing access to RT equipment and trained health care professionals, ensuring quality of care, providing guidance on priority setting with limited resources, and encouraging innovation to increase the economic efficiency of RT delivery. Several international initiatives are currently under way and represent important first steps toward scaling up RT in LMICs to treat lung cancer.

    Over the past few decades, the systemic therapy of breast cancer (early and advanced) has changed considerably. For the past 40-50 years, and since the discovery and further therapeutic use of tamoxifen, a selective estrogen receptor modulator, breast cancer treatment has become the model for the development and success of tailored medical treatment. Much still needs to be done in improving outcomes for all patients with breast cancer, and especially for those who have advanced breast cancer, a challenging area for medical oncologists. Ongoing international clinical trials are currently evaluating new therapeutic approaches and identifying specific biological subsets that could determine a patient's ability to respond to particular chemotherapeutic drugs.

  5. Improving management of patients with advanced cancer

    Development of bone metastases in patients with advanced cancer is associated with skeletal-related events (SREs) such as pathologic fractures, spinal cord compression, the requirement for surgery or palliative radiotherapy to bone, and hypercalcemia of malignancy. Skeletal morbidity may reduce patient mobility, limit functional independence, and impair quality of life (QOL). Proactive management of new or worsening bone pain or motor impairment is crucial because of the potential for rapid progression of symptoms. Administration of bisphosphonate therapy as a monthly infusion to patients with bone metastases prevents or delays the onset and reduces the frequency of SREs and provides clinically meaningful improvements in bone pain and QOL. In addition to administration of therapy, the monthly infusion visit allows a dedicated team of healthcare professionals to regularly assess SREs, response to therapy, adverse events (AEs), QOL, and adherence to oral medications and supplements. The continuity of care that occurs during the monthly infusion visit provides oncology nurses with an opportunity to educate patients about effective strategies to manage SREs and AEs. In addition, regular interaction provides oncology nurses with an opportunity to recognize and proactively address subtle changes in the patients’ medical condition. Using a multidisciplinary medical team also eliminates barriers between the various healthcare professionals involved in patient management. Consequently, the monthly infusion visit can result in effective patient management and improved clinical outcomes in patients with malignant bone disease. PMID:21206517

    With increase in survival and progression-free survival in the advanced metastatic cancers, the expectation of quality of life (QOL) has increased dramatically. Palliative care plays a vital role in the management of these advanced cancer patients. At present scenario, palliative care in advanced cancer has seen a completely different approach. Aggressive surgical procedures have been performed to improve the QOL in the advanced cancer patients. We report a case of advanced lung cancer with pathological femur fracture, treated with extensive total femur replacement surgery to provide better QOL. PMID:27803575

    This paper describes methods that a distribution engineer could use to determine advanced inverter settings to improve distribution system performance. These settings are for fixed power factor, volt-var, and volt-watt functionality. Depending on the level of detail that is desired, different methods are proposed to determine single settings applicable for all advanced inverters on a feeder or unique settings for each individual inverter. Seven distinctly different utility distribution feeders are analyzed to simulate the potential benefit in terms of hosting capacity, system losses, and reactive power attained with each method to determine the advanced inverter settings.

    Objectives To understand successful strategies used by people to cope well when living with advanced cancer; to explore how professionals can support effective coping strategies; to understand how to support development of effective coping strategies for patients and family carers. Design Qualitative serial (4–12 week intervals) interview study with people with advanced cancer and their informal carers followed by focus groups. The iterative design had a novel focus on positive coping strategies. Interview analysis focused on patients and carers as individuals and pairs, exploring multiple dimensions of their coping experiences. Focus group analysis explored strategies for intervention development. Participants 26 people with advanced (stage 3–4) breast, prostate, lung or colorectal cancer, or in receipt of palliative care, and 24 paired nominated informal/family carers. Setting Participants recruited through outpatient clinics at two tertiary cancer centres in Merseyside and Manchester, UK, between June 2012 and July 2013. Results 45 patient and 41 carer interviews were conducted plus 4 focus groups (16 participants). People with advanced cancer and their informal/family carers develop coping strategies which enable effective management of psychological wellbeing. People draw from pre-diagnosis coping strategies, but these develop through responding to the experience of living with advanced cancer. Strategies include being realistic, indulgence, support, and learning from others, which enabled participants to regain a sense of wellbeing after emotional challenge. Learning from peers emerged as particularly important in promoting psychological wellbeing through the development of effective ‘everyday’, non-clinical coping strategies. Conclusions Our findings challenge current models of providing psychological support for those with advanced cancer which focus on professional intervention. It is important to recognise, enable and support peoples’ own

    OBJECTIVES--To consider the role of platinum and the relative merits of single agent and combination chemotherapy in the treatment of advanced ovarian cancer. DESIGN--Formal quantitative overview using updated individual patient data from all available randomised trials (published and unpublished). SUBJECTS--8139 patients (6408 deaths) included in 45 different trials. RESULTS--No firm conclusions could be reached. Nevertheless, the results suggest that in terms of survival immediate platinum based treatment was better than non-platinum regimens (overall relative risk 0.93; 95% confidence interval 0.83 to 1.05); platinum in combination was better than single agent platinum when used in the same dose (overall relative risk 0.85; 0.72 to 1.00); and cisplatin and carboplatin were equally effective (overall relative risk 1.05; 0.94 to 1.18). CONCLUSIONS--In the past, randomised clinical trials of chemotherapy in advanced ovarian cancer have been much too small to detect the degree of benefit which this overview suggests is realistic for currently available chemotherapeutic regimens. Hence a new trial comparing cisplatin, doxorubicin, and cyclophosphamide (CAP) with carboplatin has been launched and plans to accrue 2000 patients. PMID:1834291

    Alzheimer's disease and most other causes of dementia are regressive by nature. As such one can expect patients with such types of mental impairment to gradually decline in function and ability to participate in day care activities. This paper attempts to show that with the right kind of orientation, staff can "tune into" the more advanced dementia patients, find the key to their personal needs, desires and remaining abilities and design a program that allows them not only to continue to participate in a social and therapeutic framework, but also to gain some meaningful human contact and quality of life despite their cognitive deterioration.

    We set priorities every day in both our personal and professional lives. Some decisions are easy, while others require much more thought, participation, and resources. The difficult or less appealing priorities may not be popular, may receive push-back, and may be resource intensive. Whether personal or professional, the urgency that accompanies true priorities becomes a driving force. It is that urgency to ensure our patients' safety that brings many of us to work each day. This is not easy work. It requires us to be knowledgeable about the enterprise we are working in and to have the professional skills and competence to facilitate setting the priorities that allow our organizations to minimize risk and maximize value.

    Biliary tract cancers (BTC), though uncommon, are highly fatal malignancies, and current treatments fail to cure or control the majority of tumors. Given the complexity of the anatomy and often aggressive nature of the disease, multidisciplinary treatment, including palliation, is often required. However, systemic therapy with cytotoxics and/or targeted agents are routinely the mainstay of treatment for patients with advanced biliary tract cancers, and new targets and agents provide hope for this disease. This article focuses on recent advances in the management of biliary tract cancers, with a special focus on the molecular basis for current therapeutic investigation in this disease. PMID:23416860

    Thymidine phosphorylase (TP) is known to be more concentrated in human cancer tissues than in adjacent normal tissue based on findings using enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry. However, the ultrastructural localization of TP in cancer tissues has not previously been demonstrated. We investigated the localization of TP in gastric cancer and colorectal cancer tissue by ELISA, immunohistochemistry, and immunoelectron microscopy. Between April 1997 and May 2000, we obtained surgically resected specimens from 42, 46, and 36 cases of advanced gastric, colon, and rectal cancer, respectively. ELISA demonstrated that the TP level was higher in cancer tissues than in adjacent normal tissue. Immunohistochemically, cancer cells were positive for the enzyme in some cases. However, in a number of cases immunopositive inflammatory cells were also present in cancerous tissues. At the electron microscope level, TP was diffusely distributed in the cytoplasm of cancer cells and in the mitochondria of the neutrophil in gastric cancer tissue. In rectal cancer tissues, cytoplasmic granules in macrophages in cancer tissues were immunoreactive for the TP. These findings suggest that TP is produced by macrophages and exists in neutrophils and cancer cells.

    Purpose Advances have occurred in breast cancer survivorship but, for many African American women, challenges and gaps in relevant information remain. Methods This article identifies opportunities to address disparities in breast cancer survival and quality of life, and thereby to increase breast cancer survivorship among African American women. Results For breast cancer survivors, common side effects, lasting for long periods after cancer treatment, include fatigue, loss of strength, difficulty sleeping, and sexual dysfunction. For addressing physical and mental health concerns, a variety of interventions have been evaluated, including exercise and weight training, dietary interventions, yoga and mindfulness-based stress reduction, and support groups or group therapy. Obesity has been associated with breast cancer recurrence and poorer survival. Relative to white survivors, African American breast cancer survivors are more likely to be obese and less likely to engage in physical activity, although exercise improves overall quality of life and cancer-related fatigue. Considerable information exists about the effectiveness of such interventions for alleviating distress and improving quality of life among breast cancer survivors, but few studies have focused specifically on African American women with a breast cancer diagnosis. Studies have identified a number of personal factors that are associated with resilience, increased quality of life, and positive adaptation to a breast cancer diagnosis. Conclusions There is a need for a better understanding of breast cancer survivorship among African American women. Additional evaluations of interventions for improving the quality of life and survival of African American breast cancer survivors are desirable. PMID:26303657

    Cancer is a leading cause of death worldwide; due to the lack of ideal cancer biomarkers for early detection or diagnosis, most patients present with late-stage disease at the time of diagnosis, thus limiting the potential for successful treatment. Traditional cancer treatments, including surgery, chemotherapy and radiation therapy, have demonstrated very limited efficacy for patients with late-stage disease. Therefore, innovative and effective cancer treatments are urgently needed for cancer patients with late-stage and refractory disease. Cancer immunotherapy, particularly adoptive cell transfer, has shown great promise in the treatment of patients with late-stage disease, including those who are refractory to standard therapies. In this review, we will highlight recent advances and discuss future directions in adoptive cell transfer based cancer immunotherapy.

Besides improvements in surgical techniques, both neoadjuvant short-course radiotherapy and long-course chemoradiation improve oncological results. Approximately 40–60% of rectal cancer patients treated with neoadjuvant chemoradiation achieve some degree of pathologic response. However, there is no effective method of predicting which patients will respond to neoadjuvant treatment. Recent studies have evaluated the potential of genetic biomarkers to predict outcome in locally advanced rectal adenocarcinoma treated with neoadjuvant chemoradiation. The articles produced by the PubMed search were reviewed for those specifically addressing a genetic profile's ability to predict response to neoadjuvant treatment in rectal cancer. Although tissue gene microarray profiling has led to promising data in cancer, to date, none of the identified signatures or molecular markers in locally advanced rectal cancer has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice.

    The reported incidence of local recurrence after mastectomy for locally advanced breast cancer (TNM Stage III and IV) is between 30% and 50%. The purpose of this study was to evaluate the effect of radiation therapy (XRT) followed by total mastectomy on the incidence of local recurrence in patients with locally advanced breast cancer. Fifty-three patients who presented with locally advanced breast cancer, without distant metastases, were treated with XRT (4500-5000 R) to the breast, chest wall, and regional lymph nodes. Five weeks after completion of XRT, total mastectomy was performed. There were no operative deaths. The complications that occurred in 22 patients after surgery were flap necrosis, wound infection, and seroma. Patients have been followed from 3 to 134 months. Twenty-five patients are alive (3-134 months), 12 free of disease; 28 patients have died with distant metastases (6-67 months). Isolated local recurrence occurred in only two patients. Four patients had local and distant recurrence (total local recurrence is 6/53). The remaining patients all developed distant metastases. We have devised a treatment strategy which significantly decreases the incidence of local recurrence in patients with locally advanced breast cancer. However, the rapid appearance of distant metastases emphasizes the need for systemically active therapy in patients with locally advanced breast cancer. PMID:3994434

    Gastric cancer currently ranks fourth in cancer-related mortality worldwide. In the western world, it is most often diagnosed at an advanced stage, after becoming metastatic at distant sites. Patients with advanced disease (locally advanced or metastatic) have a somber prognosis, with a median overall survival of 10-12 mo, and palliative chemotherapy is the mainstay of treatment. In recent years, novel approaches using inhibition of human epidermal growth factor receptor 2 (HER2) have demonstrated significant improvements in progression-free and overall survival, compared with chemotherapy alone, in first-line treatment of patients with overexpression of HER2. In addition, both second-line chemotherapy and treatment with the vascular endothelial growth factor receptor-inhibitor ramucirumab demonstrated significant benefits in terms of overall survival, compared with best supportive care, in randomized studies. Moreover, ramucirumab in combination with chemotherapy demonstrated further significant benefits in terms of progression-free and overall survival, compared with chemotherapy alone, in second-line treatment for patients with metastatic gastric cancer. A recently published molecular classification of gastric cancer is expected to improve patient stratification and selection for clinical trials and provide a roadmap for future drug development. Nevertheless, despite these developments the prognosis of patients with advanced gastric cancer remains poor. In this review we discuss current standards of care and outline major topics of drug development in gastric cancer. PMID:26937129

    Prostate cancer continues to be one of the most serious afflictions of men of advanced age, remaining the most commonly diagnosed and second leading cause of cancer-related deaths in American men. The treatment options for patients with incurable metastatic, castrate-resistant disease have long focused on various chemotherapeutic approaches, which provide a slight survival benefit while being associated with potentially significant side effects. However, the recent approval of sipuleucel-T has given patients with advanced disease an additional treatment option that has demonstrated benefit without the side effects associated with chemotherapy. Sipuleucel-T is an antigen-presenting cell-based active immunotherapy that utilizes a patient's own immune cells, presumably to activate an antigen-specific immune response against tumor cells. This review focuses on the development and implementation of sipuleucel-T as a therapy for prostate cancer. Specifically, we present some of the issues associated with the management of advanced prostate cancer, the research and development that led to the approval of sipuleucel-T, how the approval of sipuleucel-T could change the clinical management of prostate cancer, and current and future areas of investigation that are being pursued with regard to sipuleucel-T and other treatments for advanced prostate cancer.

    Myofascial pain syndrome is started to be recognized as one of important factors of pain in cancer patients. However, no reports on features of myofascial trigger points were found in terminally-ill cancer populations. This time, we encountered 5 patients with myofascial pain syndrome and terminal cancer in whom delirium developed due to increased doses of opioid without a diagnosis of myofascial pain syndrome on initial presentation. The delirium subsided with dose reductions of opioid and treatment of myofascial pain syndrome. The common reason for a delayed diagnosis among the patients included an incomplete palpation of the painful sites, which led to unsuccessful myofascial trigger points identification. The features of myofascial trigger points included single onset in the cancer pain management site with opioid and the contralateral abdominal side muscles of the non-common sites. Withdrawal reflexes associated with cancer pain in the supine position, which are increasingly seen in the terminal cancer patients, were considered to have contributed to this siuation. We consider that careful palpation of the painful site is important, in order to obtain greater knowledge and understanding of the features of myofascial trigger points. PMID:26962285

    While men with early stage prostate cancer typically enjoy long-term survival after definitive management, for those who present with locally advanced or metastatic disease, survival is compromised. Multimodality therapy can prolong survival in these patients, with state-of-the-art options including intensity-modulated radiation or brachytherapy in conjunction with androgen ablation, adjuvant androgen ablation and/or chemotherapy with radical retropubic prostatectomy. In addition, novel biological therapies are being explored to target the unique molecular changes in prostate cancer cells and their interactions with the microenvironment. With these advances the outlook will undoubtedly improve, even for patients presenting with advanced disease. Careful application of these emerging therapies to a select group of prostate cancer patients most likely to obtain benefit from them is the challenge for urologists, medical oncologists and radiation oncologists for the future.

  3. Nanovector-based therapies in advanced pancreatic cancer

    2011-01-01

    Systemic therapy for advanced pancreatic cancer has been largely disappointing owing to the unfavorable pharmacokinetic profile and poor penetration of current chemotherapeutic agents ,as well as the fragile patient population with compromised tolerance to toxic chemotherapies. Nanovectors can provide passive drug delivery through abnormal tumor neo-vasculature microanatomy or active targeting via binding to receptors or macromolecules associated with the tumor. In such a manner, nanovector-based therapy may not only modulate the pharmacokinetics and therapeutic index of chemotherapeutic agents but also provide new treatment options in patients with advanced pancreatic cancer. In this article, we present the rationale and currently available clinical results of nanovector-based therapies to highlight the potential use of this class of agent in patients with advanced pancreatic cancer.

    The basic principle of the photodynamic effect was discovered over a hundred years ago leading to the pioneering work on PDT in Europe. It was only during the 1980s, however, when "photoradiation therapy" was investigated as a possible treatment modality for cancer. Photodynamic therapy (PDT) is a photochemotherapeutic process which requires the use of a photosensitizer (PS) that, upon entry into a cancer cell is targeted by laser irradiation to initiate a series of events that contribute to cell death. PSs are light-sensitive dyes activated by a light source at a specific wavelength and can be classified as first or second generation PSs based on its origin and synthetic pathway. The principle of PS activation lies in a photochemical reaction resulting from excitation of the PS producing singlet oxygen which in turn reacts and damages cell organelles and biomolecules required for cell function and ultimately leading to cell destruction. Several first and second generation PSs have been studied in several different cancer types in the quest to optimize treatment. PSs including haematoporphyrin derivative (HpD), aminolevulinic acid (ALA), chlorins, bacteriochlorins, phthalocyanines, naphthalocyanines, pheophorbiedes and purpurins all require selective uptake and retention by cancer cells prior to activation by a light source and subsequent cell death induction. Photodynamic diagnosis (PDD) is based on the fluorescence effect exhibited by PSs upon irradiation and is often used concurrently with PDT to detect and locate tumours. Both laser and light emitting diodes (LED) have been used for PDT depending on the location of the tumour. Internal cancers more often require the use of laser light delivery using fibre optics as delivery system while external PDT often make use of LEDs. Normal cells have a lower uptake of the PS in comparison to tumour cells, however the acute cytotoxic effect of the compound on the recovery rate of normal cells is not known. Subcellular

    Over the past few decades, the systemic therapy of breast cancer (early and advanced) has changed considerably. For the past 40–50 years, and since the discovery and further therapeutic use of tamoxifen, a selective estrogen receptor modulator, breast cancer treatment has become the model for the development and success of tailored medical treatment. Much still needs to be done in improving outcomes for all patients with breast cancer, and especially for those who have advanced breast cancer, a challenging area for medical oncologists. Ongoing international clinical trials are currently evaluating new therapeutic approaches and identifying specific biological subsets that could determine a patient’s ability to respond to particular chemotherapeutic drugs.

    Advances in our ability to assay molecular processes, including gene expression, protein expression, and molecular and cellular biochemistry, have fueled advances in our understanding of breast cancer biology and have led to the identification of new treatments for patients with breast cancer. The ability to measure biologic processes without perturbing them in vivo allows the opportunity to better characterize tumor biology and to assess how biologic and cytotoxic therapies alter critical pathways of tumor response and resistance. By accurately characterizing tumor properties and biologic processes, molecular imaging plays an increasing role in breast cancer science, clinical care in diagnosis and staging, assessment of therapeutic targets, and evaluation of responses to therapies. This review describes the current role and potential of molecular imaging modalities for detection and characterization of breast cancer and focuses primarily on radionuclide-based methods.

    Oncolytic virotherapy is a novel cancer therapy. Vaccine-attenuated strains of measles virus(MV)is an ideal candidate for oncolytic virotherapy which has an excellent safety record. Vaccine-attenuated MV uses CD46 and Nectin-4 molecule as major entry receptors into cells. Vaccine-attenuated MV can selectively infect and kill a wide variety of cancer cells in vitro and in vivo. With the development of molecular cloning, scientists have successfully rescued cDNA of vaccine-attenuated MV and increased its oncolytic efficiency with molecular engineering techniques. Phase I clinical trials of virotherapy for ovarian cancer and multiple myeloma with vaccine-attenuated MV are underway. The preliminary results indicate the promising antitumor potential of vaccine-attenuated MV.

    Squamous cell lung cancer (SQCLC) is an aggressive type of lung cancer and most are diagnosed at advanced stage. Patients with advanced SQCLC tend to be older, current or former smoker, with central type tumour located near large blood vessels and seldom with druggable genetic alternations. Consequently, progress of targeted therapy and antivascular agents available in lung adenocarcinoma could not be duplicated in this subset of patients. The treatment paradigms have long been dominant by cytotoxic agents and posed many therapeutic challenges. Until recent years, immune checkpoint inhibitors, other monoclonal antibodies and afatinib have been approved for treatment of advanced SQCLC, presenting a novel treatment landscape and initiating the era of precision medicine in this subset of patients. This review will summarise the recent treatment progresses in advanced SQCLC with a focus on checkpoint inhibitors of programmed cell death-1 receptor or its ligand, and discuss the emerging challenges in this new era.

    Colorectal cancer is the most frequent malignancy in both sexes in Spain. Between 20% and 25% of affected individuals have a family history of the disease, and 5% to 6% have a germ mutation, i.e. the disease develops in the context of a hereditary syndrome. The importance of identifying patients with hereditary syndromes predisposing them to colorectal cancer lies in the possibility of applying preventive measures, screening, and more appropriate management of both patients and their families. The present article outlines the most important studies presented at the congress of the American Gastroenterological Association.

    The vast majority of patients with differentiated thyroid cancer (DTC) are treated successfully with surgery and radioactive iodine ablation, yet the treatment of advanced cases is frustrating and largely ineffective. Systemic treatment with conventional cytotoxic chemotherapy is basically ineffective in most patients with advanced DTC. However, a better understanding of the genetics and biologic basis of thyroid cancers has generated opportunities for innovative therapeutic modalities, resulting in several clinical trials. We aim to delineate the latest knowledge regarding the biologic characteristics of DTC and to describe the available data related to novel targeted therapies that have demonstrated clinical effectiveness.

    2014-02-28

    Colon cancer is the second leading cause of cancer mortality in the United States with a median age at diagnosis of 69 years. Sixty percent are diagnosed over the age of 65 years and 36% are 75 years or older. At diagnosis, approximately 58% of patients will have locally advanced and metastatic disease, for which systemic chemotherapy has been shown to improve survival. Treatment of cancer in elderly patients is more challenging due to multiple factors, including disabling co-morbidities as well as a decline in organ function. Cancer treatment of elderly patients is often associated with more toxicities that may lead to frequent hospitalizations. In locally advanced disease, fewer older patients receive adjuvant chemotherapy despite survival benefit and similar toxicity when compared to their younger counterparts. A survival benefit is also observed in the palliative chemotherapy setting for elderly patients with metastatic disease. When treating elderly patients with colon cancer, one has to consider drug pharmacokinetics and pharmacodynamics. Since chronological age is a poor marker of a patient's functional status, several methods of functional assessment including performance status and activities of daily living (ADL) or instrumental ADL, or even a comprehensive geriatric assessment, may be used. There is no ideal chemotherapy regimen that fits all elderly patients and so a regimen needs to be tailored for each individual. Important considerations when treating elderly patients include convenience and tolerability. This review will discuss approaches to the management of elderly patients with locally advanced and metastatic colon cancer.

    BACKGROUND Although advances in early detection and treatment of cancer improve overall population survival, these advances may not benefit all population groups equally, and may heighten racial/ethnic (R/E) differences in survival. METHODS We identified cancer cases in the Surveillance, Epidemiology, and End Results program, who were ≥ 20 years and diagnosed with one invasive cancer in 1995–1999 (n=580,225). We used 5-year relative survival rates (5Y-RSR) to measure the degree to which mortality from each cancer is amenable to medical interventions (amenability index). We used Kaplan-Meier methods and Cox proportional hazards regression to estimate survival differences between each R/E minority group relative to whites, by the overall amenability index, and three levels of amenability (non-amenable, partly and mostly amenable cancers, corresponding to cancers with 5Y-RSR <40%, 40–69% and ≥ 70%, respectively), adjusting for gender, age, disease stage and county-level poverty concentration. RESULTS As amenability increased, R/E differences in cancer survival increased for African Americans, American Indians/Native Alaskans and Hispanics relative to whites. For example, the hazard rate ratios (95% confidence intervals) for African Americans vs. whites from non-amenable, partly amenable and mostly amenable cancers were 1.05 (1.03, 1.07), 1.38 (1.34,1.41), and 1.41 (1.37, 1.46), respectively. Asians/Pacific Islanders had similar or longer survival relative to whites across amenability levels; however, several subgroups experienced increasingly poorer survival with increasing amenability. CONCLUSIONS Cancer survival disparities for most R/E minority populations widen as cancers become more amenable to medical interventions. Efforts in developing cancer control measures must be coupled with specific strategies for reducing the expected disparities. PMID:19789367

    We review the current status of proteomics for esophageal cancer (EC) from a clinician's viewpoint. The ultimate goal of cancer proteomics is the improvement of clinical outcome. The proteome as a functional translation of the genome is a straightforward representation of genomic mechanisms that trigger carcinogenesis. Cancer proteomics has identified the mechanisms of carcinogenesis and tumor progression, detected biomarker candidates for early diagnosis, and provided novel therapeutic targets for personalized treatments. Our review focuses on three major topics in EC proteomics: diagnostics, treatment, and molecular mechanisms. We discuss the major histological differences between EC types, i.e., esophageal squamous cell carcinoma and adenocarcinoma, and evaluate the clinical significance of published proteomics studies, including promising diagnostic biomarkers and novel therapeutic targets, which should be further validated prior to launching clinical trials. Multi-disciplinary collaborations between basic scientists, clinicians, and pathologists should be established for inter-institutional validation. In conclusion, EC proteomics has provided significant results, which after thorough validation, should lead to the development of novel clinical tools and improvement of the clinical outcome for esophageal cancer patients.

    SUMMARY Toward development of a precision medicine framework for metastatic, castration resistant prostate cancer (mCRPC), we established a multi-institutional clinical sequencing infrastructure to conduct prospective whole exome and transcriptome sequencing of bone or soft tissue tumor biopsies from a cohort of 150 mCRPC affected individuals. Aberrations of AR, ETS genes, TP53 and PTEN were frequent (40–60% of cases), with TP53 and AR alterations enriched in mCRPC compared to primary prostate cancer. We identified novel genomic alterations in PIK3CA/B, R-spondin, BRAF/RAF1, APC, β-catenin and ZBTB16/PLZF. Aberrations of BRCA2, BRCA1 and ATM were observed at substantially higher frequencies (19.3% overall) than seen in primary prostate cancers. 89% of affected individuals harbored a clinically actionable aberration including 62.7% with aberrations in AR, 65% in other cancer-related genes, and 8% with actionable pathogenic germline alterations. This cohort study provides evidence that clinical sequencing in mCRPC is feasible and could impact treatment decisions in significant numbers of affected individuals. PMID:26000489

    Breast cancer is a disease that occurs most often in female cancer patients. Early detection can significantly reduce the mortality rate. Microwave breast imaging, which is noninvasive and harmless to human, offers a promising alternative method to mammography. This paper presents a review of recent advances in microwave imaging for breast cancer detection. We conclude by introducing new research on a microwave imaging system with time-domain measurement that achieves short measurement time and low system cost. In the time-domain measurement system, scan time would take less than 1 sec, and it does not require very expensive equipment such as VNA. PMID:28096808

    Remarkable advances have been made in cancer immunotherapy. Recent treatment strategies, especially chimeric antigen receptor-T (CAR-T) cell therapy and immune checkpoint inhibitors, reportedly achieve higher objective responses and better survival rates than previous immunotherapies for patients with treatment-resistant malignancies, creating a paradigm shift in cancer treatment. Several clinical trials of cancer immunotherapy for patients with various malignancies are ongoing. However, those with certain malignancies, such as low-immunogenic cancers, cannot be successfully treated with T-cell immunotherapy, and subsets of immunotherapy-treated patients relapse, meaning that more effective immunotherapeutic strategies are needed for such patients. Furthermore, the safety, convenience, and cost of cancer immunotherapy need to be improved in the near future. Herein, we discuss recent advances and future challenges in cancer immunotherapy, i.e., the identification of neoantigens for the development of individualized immunotherapies, the development of new CAR-T cell therapies, including so-called armored CAR-T cells that can induce greater clinical effects and thereby achieve longer survival, the development of off-the-shelf treatment regimens using non-self cells or cell lines, and effective cancer immunotherapy combinations.

    Background The main goal of anti-cancer therapy is to specifically inhibit the malignant activity of cancer cells, while leaving healthy cells unaffected. As such, for every proposed therapy, it is important to keep in mind the therapeutic index — the ratio of the toxic dose over the therapeutic dose. The use of immunotherapy has allowed a means to both specifically block protein–protein interaction and deliver cytotoxic events to a tumor-specific antigen. Review scope It is the objective of this review to give an overview on current immunotherapy treatment for cancers using monoclonal antibodies. We demonstrate three exciting targets for immunotherapy, TNF-α Converting Enzyme (TACE), Cathepsin S and Urokinase Plasmogen Activator and go over the advances made with one of the most used monoclonal antibodies in cancer therapy, Rituximab; as well as Herceptin, which is used for breast cancer therapy. Furthermore, we touch on other venues of immunotherapy, such as adaptive cell transfer, the use of nucleic acids and the use of dendritic cells. Finally, we summarize some ongoing studies that spell tentative advancements for anti-cancer immunotherapy. General significance Immunotherapy is at the forefront of anti-cancer therapies, allying both a high degree of specificity to general high effectiveness and fewer side-effects. PMID:26673349

    A kinetic enzyme-linked immunosorbent assay (ELISA) for plasma tissue inhibitor of metalloproteinase (TIMP)-1 was developed in order to examine the potential diagnostic and prognostic value of TIMP-1 measurements in cancer patients. The ELISA enabled specific detection of total TIMP-1 in EDTA, citrate and heparin plasma. The assay was rigorously tested and requirements of sensitivity, specificity, stability and good recovery were fulfilled. TIMP-1 levels measured in citrate plasma (mean 69.2 ± 13.1 μg l−1) correlated with TIMP-1 measured in EDTA plasma (mean 73.5 ± 14.2 μg l−1) from the same individuals in a set of 100 healthy blood donors (Spearman's rho = 0.62, P < 0.0001). The mean level of TIMP-1 in EDTA plasma from 143 patients with Dukes' stage D colorectal cancer was 240 ± 145 μg l−1 and a Mann–Whitney test demonstrated a highly significant difference between TIMP-1 levels in healthy blood donors and colorectal cancer patients (P < 0.0001). Similar findings were obtained for 19 patients with advanced breast cancer (mean 292 ± 331 μg l−1). The results show that TIMP-1 is readily measured in plasma samples by ELISA and that increased levels of TIMP-1 are found in patients with advanced cancer. It is proposed that plasma measurements of TIMP-1 may have value in the management of cancer patients. © 1999 Cancer Research Campaign PMID:10408859

    The most immediate strategy for improving survival of gastric cancer patients is secondary prevention through diagnosis of early gastric cancer either through screening or follow-up of individuals at high risk. Endoscopy examination is therefore of paramount importance and two general steps are to be known in assessing gastric mucosa - detection and characterization. Over the past decade, the advent of advanced endoscopic imaging technology led to diverse descriptions of these modalities reporting them to be useful in this setting. In this review, we aim at summarizing the current evidence on the use of advance imaging in individuals at high-risk (i.e., advance stages of gastric atrophy/intestinal metaplasia) and in those harbouring neoplastic lesions, and address its potential usefulness providing the readers a framework to use in daily practice. Further research is also suggested.

    The application of modern molecular tests such as next-generation sequencing (NGS) to human malignancies has led to better understanding of tumor biology and the design of targeted molecular therapies. In the research setting, important genomic alterations in tumors have been discovered with potential therapeutic implications but data regarding the impact of this technology in a real world oncology practice is limited. As a result, we decided to review the results of NGS in 144 advanced-stage cancer patients referred to the oncology practices of Lifespan-affiliated centers in Rhode Island. Most cancers revealed genomic alterations in genes commonly mutated in cancer. However, several unexpected genomic alterations were discovered in certain cancers with potential therapeutic intervention. Most cancers contained "actionable" genomic alterations despite being of advanced stage. Our experience demonstrates that application of NGS in the clinical setting contributes both to increasing the therapeutic armamentarium as well as our understanding of tumor biology.

    Lung cancer is the most common cancer in the world and pain is its most common symptom. Pain can be brought about by several different causes including local effects of the tumor, regional or distant spread of the tumor, or from anti-cancer treatment. Patients with lung cancer experience more symptom distress than patients with other types of cancer. Symptoms such as pain may be associated with worsening of other symptoms and may affect quality of life. Pain management adheres to the principles set out by the World Health Organization’s analgesic ladder along with adjuvant analgesics. As pain can be caused by multiple factors, its treatment requires pharmacological and non-pharmacological measures from a multidisciplinary team linked in with specialist palliative pain management. This review article examines pain management in lung cancer. PMID:23115483

    A 70-year-old man is referred to a urologist for recommendations on the management of metastatic prostate cancer. His cancer was diagnosed 5 years ago, and he underwent radical prostatectomy at that time. The tumour was confined to the prostate gland (Gleason score 7), and during surgery the lymph nodes were assessed as being clear of cancer. Before the surgery, the patient's prostate-specific antigen (PSA) level had been 8 ng/mL. After the prostatectomy, PSA was at first undetectable, but recently the PSA level rose to 2 ng/mL and then, at the most recent test, to 16 ng/mL. A bone scan was ordered to investigate back discomfort, which has been persistent but easily controlled with acetaminophen. Unfortunately, the bone scan shows several sites of metastatic disease. The man's medical history includes type 2 diabetes, which has developed during the past 3 years and which is controlled by diet, as well as asymptomatic hypertension, which is managed by means of a thiazide diuretic. The patient asks what treatments are available, what impact they are likely to have on his disease and what risks are associated with the therapies. PMID:9951446

    The principal role of the immune system is to prevent and eradicate pathogens and infections. The key characteristics or features of an effective immune response include specificity, trafficking, antigen spread and durability (memory). The immune system is recognised to have a critical role in controlling cancer through a dynamic relationship with tumour cells. Normally, at the early stages of tumour development, the immune system is capable of eliminating tumour cells or keeping tumour growth abated; however, tumour cells may evolve multiple pathways over time to evade immune control. Immunotherapy may be viewed as a treatment designed to boost or restore the ability of the immune system to fight cancer, infections and other diseases. Immunotherapy manifests differently from traditional cancer treatments, eliciting delayed response kinetics and thus may be more effective in patients with lower tumour burden, in whom disease progression may be less rapid, thereby allowing ample time for the immunotherapy to evolve. Because immunotherapies may have a different mechanism of action from traditional cytotoxic or targeted biological agents, immunotherapy techniques have the potential to combine synergistically with traditional therapies.

    -time information that can inform the care of every patient with cancer as well as connect patients with their entire medical teams. The rapid learning system will form a continuous cycle of learning: securely capturing data from every patient at the point of care, drawing on evidence-based guidelines, and evaluating quality of care against those standards and the outcomes of other patients. Clinical trials are another area in which collaboration is critical. Increasing clinical trial participation will require commitment across the cancer community from physicians, patients, insurers, hospitals, and industry. A 2010 report by the Institute of Medicine described challenges to participation in trials by both physicians and patients and provided recommendations for revitalizing clinical trials conducted through the National Cancer Institute's Cooperative Group Program. ASCO has pledged its support for the full implementation of these recommendations. More broadly, ASCO recently outlined a bold vision for translational and clinical cancer research for the next decade and made recommendations to achieve that vision. Accelerating Progress Against Cancer: ASCO's Blueprint for Transforming Clinical and Translational Research, released in November, calls for a research system that takes full advantage of today's scientific and technologic opportunities and sets a high-level agenda for policy makers, regulators, and advocates. Cancer research has transformed cancer care in the past forty years, and this year's Clinical Cancer Advances illustrates how far we have come in the past year alone. We now have a tremendous opportunity to use today's knowledge and collaborate across all facets of cancer care to conquer this deadly disease. Michael P.

  11. Advances in pancreatic cancer research: moving towards early detection.

    Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal forms of cancer. Substantial progress has been made in the understanding of the biology of pancreatic cancer, and advances in patient management have been significant. However, most patients (nearly 80%) who present with locally advanced or metastatic disease have an extremely poor prognosis. Survival is better for those with malignant disease localized to the pancreas, because surgical resection at present offers the only chance of cure. Therefore, the early detection of pancreatic cancer may benefit patients with PDAC. However, its low rate of incidence and the limitations of current screening strategies make early detection difficult. Recent advances in the understanding of the pathogenesis of PDAC suggest that it is possible to detect PDAC in early stages and even identify precursor lesions. The presence of new-onset diabetes mellitus in the early phase of pancreatic cancer may provide clues for its early diagnosis. Advances in the identification of novel circulating biomarkers including serological signatures, autoantibodies, epigenetic markers, circulating tumor cells and microRNAs suggest that they can be used as potential tools for the screening of precursors and early stage PDAC in the future. However, proper screening strategies based on effective screening methodologies need to be tested for clinical application.

    Over the last several decades advances in the management and treatment of patients with liver metastases from colorectal cancer (CRC) has changed a disease with a dismal prognosis to one with a potential for cure in some patients. Advances have been made through coordinated management of patients by surgeons, medical oncologists, radiologists, and other health care professionals coupled with advances in treatment options. Although these advances have clearly impacted patient outcomes, it is clear that the benefit of traditional surgical approaches and the use of cytoxic chemotherapy are reaching a plateau. Continued research to develop new and more active therapies, including targeted or biologic agents, is needed. This review discusses the advances made in management of patients with liver-limited metastatic disease.

    The purpose of this study was to identify dietary patterns among patients with advanced cancer. Differences between cancer groups are described, and food groups contributing higher proportions to overall caloric intake are identified. Patients with advanced cancer (n=51) were recruited from a regional cancer centre and completed a three-day dietary record. Food items were categorized according to macronutrient content. After adjustment for body weight, substantial variation in energy intake was observed (range: 13.7 to 55.4 kcal/kg/day). For 49% of patients, protein intake was below recommendations. Overall, patients consumed the largest proportion of their calories from meat (16%), other foods (11%), dessert (9%), fruit (9%), white bread (7%), and milk (7%). Only 5% of patients consumed meal replacement supplements. The results of this descriptive study provide important insights into the dietary habits of patients with advanced cancer. These insights could be translated into the development of effective recommendations for maintaining or improving health and quality of life.

    Abstract Rationale: Apatinib is a novel anti-angiogenic agent targeting vascular endothelial growth factor receptor-2, which is effective in patients with chemotherapy-refractory gastric cancer. There are no reports of concurrent apatinib with local radiation therapy in elderly patients with advanced gastric cancer. Patient concerns and Diagnoses: we present the first published report of a 70-year-old male patient with advanced gastric cancer who received concurrent apatinib and local radiation therapy after failure of oxaliplatin and S-1 chemotherapy. Interventions and Outcomes: The patient received concurrent apatinib and local radiation therapy and was followed up 7 months after therapy without disease progress, 14 months later indicated extensive metastasis and this patient died of pulmonary infection. Lessons: Elderly patients with advanced gastric cancer may benefit from concurrent apatinib with local radiation therapy when chemotherapy is not tolerated or successful. Further studies are needed to investigate the clinical outcomes and toxicities associated with concurrent apatinib and radiation therapy in gastric cancer. PMID:28248891

  16. Validation of actigraphy to assess circadian organization and sleep quality in patients with advanced lung cancer

    PubMed Central

    2011-01-01

    Background Many cancer patients report poor sleep quality, despite having adequate time and opportunity for sleep. Satisfying sleep is dependent on a healthy circadian time structure and the circadian patterns among cancer patients are quite abnormal. Wrist actigraphy has been validated with concurrent polysomnography as a reliable tool to objectively measure many standard sleep parameters, as well as daily activity. Actigraphic and subjective sleep data are in agreement when determining activity-sleep patterns and sleep quality/quantity, each of which are severely affected in cancer patients. We investigated the relationship between actigraphic measurement of circadian organization and self-reported subjective sleep quality among patients with advanced lung cancer. Methods This cross-sectional and case control study was conducted in 84 patients with advanced non-small cell lung cancer in a hospital setting for the patients at Midwestern Regional Medical Center (MRMC), Zion, IL, USA and home setting for the patients at WJB Dorn Veterans Affairs Medical Center (VAMC), Columbia, SC, USA. Prior to chemotherapy treatment, each patient's sleep-activity cycle was measured by actigraphy over a 4-7 day period and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Results The mean age of our patients was 62 years. 65 patients were males while 19 were females. 31 patients had failed prior treatment while 52 were newly diagnosed. Actigraphy and PSQI scores showed significantly disturbed daily sleep-activity cycles and poorer sleep quality in lung cancer patients compared to healthy controls. Nearly all actigraphic parameters strongly correlated with PSQI self-reported sleep quality of inpatients and outpatients. Conclusions The correlation of daily activity/sleep time with PSQI-documented sleep indicates that actigraphy can be used as an objective tool and/or to complement subjective assessments of sleep quality in patients with advanced

    2008-04-01

    The purpose of this study is to update the management of pregnant women with advanced cervical cancer, thanks to a literature review indexed in Medline((R)) (from 1980 till 2006 using those keywords: advanced cervix cancer, neoadjuvant chemotherapy and pregnancy), ScienceDirect (from 1990 till 2006) and the French Encyclopédie Médico-Chirurgicale. It occurs that pregnancy is a privileged period to diagnose cervical cancer, particularly in early stages. We ought to beware of symptoms such as vaginal bleeding, which could be underestimated during pregnancy. Colposcopically selected biopsies are reference techniques to confirm the diagnostic. The assessment of extension includes an abdominal and pelvic MRI and echography and a radiography of the chest for locally advanced stages. The decision to interrupt pregnancy should be based on a collegial evaluation and depends on state and histology of disease, patient's desire for pregnancy, as well as gestational age and disease evolution. Cesarean is preferred to natural delivery even though survival rates are the same. The cesarean section prevents from short-term complications and recurrence on the episiotomy, but the hysterotomy type is controversial throughout literature. The prognosis of cervical cancer does not seem to be influenced by pregnancy. Management is the same, even though we have to adapt the treatment from the pregnancy state. No study could show the benefit and the safety of neoadjuvant chemotherapy during pregnancy, due to few cases, but it could be a solution with patients suffering from an advanced cancer and not willing to stop pregnancy. To conclude, the detection by cervical smears should be systematic during pregnancy. When cancer is diagnosed, cesarean section is the favourite way to deliver. Pregnancy does not modify disease's prognosis and the therapeutic choice depends on the stage of the disease.

    Poor prognosis of anaplastic thyroid cancer and advanced disease in differentiated and medullary thyroid cancer, together with absence of effective therapeutic measures, has induced recent intensified basic and clinical research in this area. The aim of this article is to assess the effects of new drug treatment for advanced thyroid cancer. We searched MEDLINE and EMBASE until the end of September 2011 for relevant data. Further sources were reference lists of original publications and review articles. We included prospective studies that investigated drug interventions for advanced thyroid cancer published in any language. We did not include trials solely communicated as abstracts. For inclusion, studies had to report overall survival, progression-free survival or similar, or response outcomes. Data were extracted by one author and checked by the other. All tables are part of this publication. Because only non-comparative studies were included, we had to focus on descriptive analysis. Twenty-four studies with 715 patients were included; 18 studies investigated kinase inhibitors, the remainder various drugs. All studies reported response (only one complete response was observed; proportions of partial response were up to 49%). Median progression-free survival was about 12 months, ranging from 3.7 to 27.9 months. Adverse events (at least grade 3) of kinase inhibitors included hypertension, hand foot syndrome and diarrhoea (10%, 16% and 9%, respectively). Due to bias-prone data, any interpretation of newer pharmacotherapy options for advanced thyroid cancer is limited because only non-comparative studies could be included. Therefore, we strongly argue the need for adequate randomized controlled trials that should provide a better basis for therapeutic decision making in thyroid cancer.

    Lung cancer is one of the most important chronic diseases in the field of respiratory medicine. Conventional treatment strategies for lung cancer include chemotherapy, surgery and radiation therapy. These current therapies lack specificity and are limited by undesirable toxicities in normal cells, as well as a high rate of recurrence.Nanotechnological intervention has greatly revolutionized the therapy of lung cancer by surmounting the current limitations in conventional therapies. Nanoparticles (NPs) achieve preferential accumulation in the tumor cells by employing two mechanisms: passive and active targeting. Several nanoscale drug delivery systems for lung cancer treatment are currently in clinical trials and few of them are already commercially available. Recently, the interest to develop pulmonary delivery system of nano-based drug formulations suitable for lung cancer has been also increased which have resulted in more effective and advanced treatment of Lung cancer. However, although nanotechnology based drug carriers for lung cancer treatment have established outstanding therapeutic potential at both preclinical and clinical Phases, but there are still many limitations to be solved. This review details the till date drug nanocarriers researches performed for lung cancer therapy.

    Although there are three kinds of stupor in psychiatry, dissociative stupor is the most commonly recognized. In psychiatric clinics or emergency rooms, dissociative stupor is common, but in an oncology setting it is hardly known. Therefore, distinguishing dissociative stupor from consciousness disorder is occasionally difficult, especially in the advanced or terminal phase. We report an advanced lung cancer patient who presented dissociative stupor mimicking consciousness disorder. It is necessary to distinguish between consciousness disorder and dissociative stupor. In addition, consultation with a psychiatrist should be taken into consideration.

    2016-12-06

    Oestrogen-receptor-positive breast cancer is the most common subtype of breast cancer. Endocrine therapies that target the dependence of this subtype on the oestrogen receptor have substantial activity, yet the development of resistance to therapy is inevitable in advanced cancer. Major progress has been made in identifying the drivers of oestrogen-receptor-positive breast cancer and the mechanisms of resistance to endocrine therapy. This progress has translated into major advances in the treatment of advanced breast cancer, with several targeted therapies that enhance the efficacy of endocrine therapy; inhibitors of mTOR and inhibitors of the cyclin-dependent kinases CDK4 and CDK6 substantially improve progression-free survival. A new wave of targeted therapies is being developed, including inhibitors of PI3K, AKT, and HER2, and a new generation of oestrogen-receptor degraders. Considerable challenges remain in patient selection, deciding on the most appropriate order in which to administer therapies, and establishing whether cross-resistance occurs between therapies.

    Lipids play critical functions in cellular survival, proliferation, interaction and death, since they are involved in chemical-energy storage, cellular signaling, cell membranes, and cell–cell interactions. These cellular processes are strongly related to carcinogenesis pathways, particularly to transformation, progression, and metastasis, suggesting the bioactive lipids are mediators of a number of oncogenic processes. The current review gives a synopsis of a lipidomic approach in tumor characterization; we provide an overview on potential lipid biomarkers in the oncology field and on the principal lipidomic methodologies applied. The novel lipidomic biomarkers are reviewed in an effort to underline their role in diagnosis, in prognostic characterization and in prediction of therapeutic outcomes. A lipidomic investigation through mass spectrometry highlights new insights on molecular mechanisms underlying cancer disease. This new understanding will promote clinical applications in drug discovery and personalized therapy. PMID:27916803

    Compared to conventional treatments, gene therapy offers a variety of advantages for cancer treatment including high potency and specificity, low off-target toxicity, and delivery of multiple genes that concurrently target cancer tumorigenesis, recurrence, and drug resistance. In the past decades, gene therapy has undergone remarkable progress, and is now poised to become a first line therapy for cancer. Among various gene delivery systems, nanoparticles have attracted much attention because of their desirable characteristics including low toxicity profiles, well-controlled and high gene delivery efficiency, and multi-functionalities. This review provides an overview on gene therapeutics and gene delivery technologies, and highlight recent advances, challenges and insights into the design and the utility of nanoparticles in gene therapy for cancer treatment.

    Squamous cell lung cancer (SQCLC) is one of the most prevalent subtypes of lung cancer worldwide, about 400,000 persons die from squamous-cell lung cancer around the world, and its pathogenesis is closely linked with tobacco exposure. Unfortunately, squamous-cell lung cancer patients do not benefit from major advances in the development of targeted therapeutics such as epidermal growth factor receptor (EGFR) inhibitors or anaplastic lymphoma kinase (ALK) inhibitors that show exquisite activity in lung adenocarcinomas with EGFR mutations or echinoderm microtubule associated protein like-4 (EML4)-ALK fusions, respectively. Major efforts have been launched to characterize the genomes of squamous-cell lung cancers. Among the new results emanating from these efforts are amplifications of the fibroblast growth factor receptor 1 (FGFR1) gene, the discoidin domain receptor 2 (DDR2) gene mutation as potential novel targets for the treatment of SQCLCs. Researchers find that there are many specific molecular targeted genes in the genome of squamous-cell lung cancer patients. These changes play a vital role in cell cycle regulation, oxidative stress, cell apoptosis, squamous epithelium differentiation, may be the candidate targeted moleculars in SQCLCs. Here, we provide a review on these discoveries and their implications for clinical trials in squamous-cell lung cancer assessing the value of novel therapeutics addressing these targets.

    Technological advances have led to the introduction of next-generation sequencing (NGS) platforms in cancer investigation. NGS allows massive parallel sequencing that affords maximal tumor genomic assessment. NGS approaches are different, and concern DNA and RNA analysis. DNA sequencing includes whole-genome, whole-exome, and targeted sequencing, which focuses on a selection of genes of interest for a specific disease. RNA sequencing facilitates the detection of alternative gene-spliced transcripts, posttranscriptional modifications, gene fusion, mutations/single-nucleotide polymorphisms, small and long noncoding RNAs, and changes in gene expression. Most applications are in the cancer research field, but lately NGS technology has been revolutionizing cancer molecular diagnostics, due to the many advantages it offers compared to traditional methods. There is greater knowledge on solid cancer diagnostics, and recent interest has been shown also in the field of hematologic cancer. In this review, we report the latest data on NGS diagnostic/predictive clinical applications in solid and hematologic cancers. Moreover, since the amount of NGS data produced is very large and their interpretation is very complex, we briefly discuss two bioinformatic aspects, variant-calling accuracy and copy-number variation detection, which are gaining a lot of importance in cancer-diagnostic assessment.

    2007-02-10

    There is a continuing need for innovative, alternative therapies for hepatocellular carcinoma (HCC). Immunotherapy of cancer is attractive because of the exquisite specificity of the immune response. Activation of an HCC-specific response can be accomplished by strategies targeting tumour-associated antigens (for example: alpha fetoprotein (AFP)) or viral antigens in those patients infected with hepatitis B or C. Uncharacterised and mutated antigens can also be targeted with whole tumour cell or tumour lysate-based immunisation strategies. Viral vectors coding for genes which make the patient's tumour immunogenic can allow the immune system to naturally evolve specificity against immunogenic target antigens. Strategies which have been tested in human clinical trials include adoptive transfer of lymphocytes, cytokine injections, autologous tumour-pulsed dendritic cells (DC) as well as AFP-derived peptides in adjuvant and pulsed onto autologous DC. These trials, testing novel immune-based interventions in HCC subjects, have resulted in immunological responses and some have impacted recurrence and survival of HCC subjects.

    2017-01-01

    Melanoma is a most dangerous and deadly type of skin cancer, and considered intrinsically resistant to both radiotherapy and chemotherapy. It has become a major public health concern as the incidence of melanoma has been rising steadily over recent decades with a 5-year survival remaining less than 5%. Detection of the disease in early stage may be curable, but late stage metastatic disease that has spread to other organs has an extremely poor prognosis with a median survival of less than 10 months. Since metastatic melanoma is unresponsive to therapy that is currently available, research is now focused on different treatment strategies such as combinations of surgery, chemotherapy and radiotherapy. The molecular basis of resistance to chemotherapy seen in melanoma is multifactorial; defective drug transport system, altered apoptotic pathway, deregulation of apoptosis and/or changes in enzymatic systems that mediate cellular metabolic machinery. Understanding of alterations in molecular processes involved in drug resistance may help in developing new therapeutic approaches to treatment of malignant melanoma. PMID:28382191

    Lung cancer is the most common cause of cancer-related mortality in men and women. Non-small cell lung cancer (NSCLC) represents close to 90% of all lung cancers. When diagnosed, >50% of patients are >65 years old. Through an improved understanding of the molecular mechanisms involved in lung oncogenesis, molecular-targeted approaches have become an essential element for the treatment of patients with NSCLC. As the toxicity profiles of the techniques are definitely more favorable compared with chemotherapy, they are particularly attractive for use in elderly patients, who are potentially more susceptible to the toxicity of systemic oncological therapies. However, studies on the activity of molecular-targeted agents in this aged patient setting are much more limited compared with those in their younger counterparts. In the present review, the literature on molecular-targeted therapy for elderly patients with advanced NSCLC is discussed. It is concluded that bevacizumab should be reserved only for highly select elderly patients with advanced NSCLC when the clinician deems it useful in the face of acceptable toxicities. In elderly patients with advanced epidermal growth factor receptor mutation-positive NSCLC, erlotinib and gefitinib appear to repeat the same favorable performance as that documented on a larger scale in the overall population of patients with activating mutations. A good toxicity profile is also confirmed for active molecules on different pathways, such as crizotinib. PMID:26870160

    Purpose Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Materials and Methods Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. Results With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Conclusion Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival. PMID:25061572

    Prostate cancer is the most common cause of cancer in men, with 137.9 new cases per 100,000 men per year. The overall 5-year survival rate for prostate cancer is very high. Up to 20% of men who undergo state-of-the art treatment for prostate cancer will develop castration-resistant prostate cancer (CRPC) within 5 years, with median survival for those with metastatic CRPC ranging from approximately 15 to 36 months in recent studies. With the advent of several new drugs in the past 5 years to treat CRPC, the challenge facing clinicians is how to best sequence or combine therapies or both to optimize outcomes. A better understanding of the disease process and the role of the androgen receptor as a target for both therapy and resistance have led to the consideration of biomarkers as an approach to aid in selecting the appropriate agent for a given patient as patients respond to or tolerate different drugs differently. Research to identify new prognostic biomarkers, which are associated with outcome measures, as well as predictive biomarkers, which predict response or resistance to therapy is ongoing. The treatment of advanced prostate cancer and the research related to biomarkers are discussed.

    While normal differentiated cells primarily use mitochondrial respiration to generate the required energy for cellular processes, most cancer cells rely on glycolysis, even in sufficient oxygen conditions. This phenomenon is known as the "Warburg effect" or aerobic glycolysis and the metabolic reprogramming of cancer cells towards this altered energy metabolism is currently recognized as one of the "hallmarks of cancer". Aerobic glycolysis underlies the rapid growth of tumor cells, with high rates of glucose consumption and lactic acid production, leading to cellular acidosis. Metabolic reprogramming renders cancer cells dependent on specific metabolic enzymes or pathways that could be exploited in cancer therapy. The development of treatments that target tumor glucose metabolism is receiving renewed attention, with several drugs targeting metabolic pathways currently in clinical trials. The search for suitable targets, however, is limited by the high plasticity of the metabolic network that can induce compensatory routes. Deregulated glucose metabolism is a prominent feature associated with resistance to classical chemotherapy or oncogene-targeted therapies, strengthening the clinical potential of combining these therapies with glycolysis inhibitors. The aim of this review is to compare the advances of different therapeutic strategies targeting the glucose "addiction" of tumor cells, highlighting their potential as effective weapons against cancer. We further discuss recent evidence for the involvement of glucose metabolism as a compensatory response to the use of drugs that target different signaling pathways, where the combination with glycolysis inhibitors could prove extraordinarily useful.

    Cancer is a metabolic disease. Cancer cells, being highly proliferative, show significant alterations in metabolic pathways such as glycolysis, respiration, the tricarboxylic acid (TCA) cycle, oxidative phosphorylation, lipid metabolism, and amino acid metabolism. Metabolites like peptides, nucleotides, products of glycolysis, the TCA cycle, fatty acids, and steroids can be an important read out of disease when characterized in biological samples such as tissues and body fluids like urine, serum, etc. The cancer metabolome has been studied since the 1960s by analytical techniques such as mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. Current research is focused on the identification and validation of biomarkers in the cancer metabolome that can stratify high-risk patients and distinguish between benign and advanced metastatic forms of the disease. In this review, we discuss the current state of prostate cancer metabolomics, the biomarkers that show promise in distinguishing indolent from aggressive forms of the disease, the strengths and limitations of the analytical techniques being employed, and future applications of metabolomics in diagnostic imaging and personalized medicine of prostate cancer.

    Increased understanding of disease-specific molecular targets of therapy has led to the regulatory approval of two drugs (vandetanib and cabozantinib) for the treatment of medullary thyroid cancer (MTC), and two agents (sorafenib and lenvatinib) for the treatment of radioactive- iodine refractory differentiated thyroid cancer (DTC) in both the USA and in the EU. The effects of these and other therapies on overall survival and quality of life among patients with thyroid cancer, however, remain to be more-clearly defined. When applied early in the disease course, intensive multimodality therapy seems to improve the survival outcomes of patients with anaplastic thyroid cancer (ATC), but salvage therapies for ATC are of uncertain benefit. Additional innovative, rationally designed therapeutic strategies are under active development both for patients with DTC and for patients with ATC, with multiple phase II and phase III randomized clinical trials currently ongoing. Continued effort is being made to identify further signalling pathways with potential therapeutic relevance in thyroid cancers, as well as to elaborate on the complex interactions between signalling pathways, with the intention of translating these discoveries into effective and personalized therapies. Herein, we summarize the progress made in molecular medicine for advanced-stage thyroid cancers of different histotypes, analyse how these developments have altered - and might further refine - patient care, and identify open questions for future research.

    Background Few national registries exist in the Caribbean, resulting in limited cancer statistics being available for the region. Therefore, estimates are frequently based on the extrapolation of mortality data submitted to the World Health Organization. Thus, regional cancer surveillance and research need promoting, and their synergy must be strengthened. However, differences between countries outweigh similarities, hampering registration and availability of data. Methods The African-Caribbean Cancer Consortium (AC3) is a broad-based resource for education, training, and research on all aspects of cancer in populations of African descent. The AC3 focuses on capacity building in cancer registration in the Caribbean through special topics, training sessions, and biannual meetings. We review the results from selected AC3 workshops, including an inventory of established cancer registries in the Caribbean region, current cancer surveillance statistics, and a review of data quality. We then describe the potential for cancer research surveillance activities and the role of policymakers. Results Twelve of 30 Caribbean nations have cancer registries. Four of these nations provide high-quality incidence data, thus covering 14.4% of the population; therefore, regional estimates are challenging. Existing research and registry collaborations must pave the way and are facilitated by organizations like the AC3. Conclusions Improved coverage for cancer registrations could help advance health policy through targeted research. Capacity building, resource optimization, collaboration, and communication between cancer surveillance and research teams are key to obtaining robust and complete data in the Caribbean.

    Immuno checkpoint inhibitors have ushered in a new era with respect to the treatment of advanced non-small-cell lung cancer. Many patients are not suitable for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (eg, gefitinib, erlotinib, and afatinib) or with anaplastic lymphoma kinase inhibitors (eg, crizotinib and ceritinib). As a result, anti-PD-1/PD-L1 and CTLA-4 inhibitors may play a novel role in the improvement of outcomes in a metastatic setting. The regulation of immune surveillance, immunoediting, and immunoescape mechanisms may play an interesting role in this regard either alone or in combination with current drugs. Here, we discuss advances in immunotherapy for the treatment of metastatic non-small-cell lung cancer as well as future perspectives within this framework. PMID:28031719

    Up until now there have been no promising drugs for the treatment of advanced thyroid cancer, but the development of novel therapeutic agents is now anticipated as a result of the advent of molecular targeted drugs that inhibit tumor growth signals or angiogenesis. Against a background in which the development of numerous molecular targeted drugs for advanced thyroid cancer is being pursued worldwide, the development of sorafenib, vandetanib, and lenvatinib is currently also under way in Japan. All three of these compounds are undergoing phase 3 trials or have been approved abroad, and because they are in the final stage of development in Japan, they are expected to be introduced in clinical settings in the near future. After they have been introduced, it will be necessary to understand the differences between these compounds and to administer them to patients appropriately.

    Purpose: To investigate the clinical application of a stereotactic body radiation therapy (SBRT) boost in locally advanced pancreatic cancer patients with a focus on local efficacy and toxicity. Methods and Materials: We retrospectively reviewed 30 patients with locally advanced and nonmetastatic pancreatic cancer who had been treated between 2004 and 2006. Follow-up duration ranged from 4 to 41 months (median, 14.5 months). A total dose of 40 Gy was delivered in 20 fractions using a conventional three-field technique, and then a single fraction of 14, 15, 16, or 17 Gy SBRT was administered as a boost without a break. Twenty-one patients received chemotherapy. Overall and local progression-free survival were calculated and prognostic factors were evaluated. Results: One-year overall survival and local progression-free survival rates were 60.0% and 70.2%, respectively. One patient (3%) developed Grade 4 toxicity. Carbohydrate antigen 19-9 response was found to be an independent prognostic factor for survival. Conclusions: Our findings indicate that a SBRT boost provides a safe means of increasing radiation dose. Based on the results of this study, we recommend that a well controlled Phase II study be conducted on locally advanced pancreatic cancer.

    Radiotherapy treatment continues to have a relevant impact in the treatment of nonsmall cell cancer (NSCLC). Use of concurrent chemotherapy and radiotherapy is considered the gold standard in the treatment of locally advanced NSCLC but clinical outcomes are not satisfactory. Introduction of new radiotherapy technology and chemotherapy regimens are under investigation in this setting with the goal to improve unsatisfactory results. We report how radiotherapy is changing in the treatment of locally advanced NSCLC.

    Pancreatic cancer is under high mortality but has few effective treatment modalities. High-intensity focused ultrasound (HIFU) is becoming an emerging approach of noninvasively ablating solid tumor in clinics. A variety of solid tumors have been tried on thousands of patients in the last fifteen years with great success. The principle, mechanism, and clinical outcome of HIFU were introduced first. All 3022 clinical cases of HIFU treatment for the advanced pancreatic cancer alone or in combination with chemotherapy or radiotherapy in 241 published papers were reviewed and summarized for its efficacy, pain relief, clinical benefit rate, survival, Karnofsky performance scale (KPS) score, changes in tumor size, occurrence of echogenicity, serum level, diagnostic assessment of outcome, and associated complications. Immune response induced by HIFU ablation may become an effective way of cancer treatment. Comments for a better outcome and current challenges of HIFU technology are also covered. PMID:25053938

    Chromatin regulatory mechanisms play a major role in the control of gene expression programs during normal development and are disrupted in specific disease states, particularly in cancer. Important mediators of chromatin regulatory processes can broadly be classified into writers, erasers, and readers of covalent chromatin modifications that modulate eukaryotic gene transcription and maintain the integrity of the genome. The reversibility and disease-specific nature of these chromatin states make these regulators attractive therapeutic targets. As such, there is an ever-increasing number of candidate therapies aimed at targeting cancer-associated chromatin states that are in various stages of preclinical and clinical development. In this review, we discuss recent advances that have been made in the rational therapeutic targeting of chromatin regulatory mechanisms and highlight certain cancers where there is a specific rationale to assess these therapeutic approaches.

    Dyspnea, nausea and vomiting, anorexia, fatigue, and sleep disturbances are common and distressing in advanced cancer. We updated previous systematic reviews of how these symptoms can be alleviated with targeted literature searches. The approach to these symptoms requires comprehensive symptom assessment; treating underlying causes when benefits exceed risks; prioritizing treatment, as patients usually have many symptoms; and addressing psychosocial and spiritual distress. For dyspnea, evidence supports systemic opioids and nonpharmacological treatments such as a fan. The strongest evidence supports metoclopramide for cancer-related nausea and octreotide for bowel obstruction. For anorexia, enteral or parenteral nutrition is indicated with obstruction and expected prognosis of at least 6 weeks. Evidence supports several drugs for appetite affecting quality of life. For fatigue, evidence supports psychosocial interventions and methylphenidate. For insomnia, evidence supports cognitive-behavioral therapy in cancer; no sleep agents have superior effectiveness.

    Experience obtained in a group of 44 patients with advanced cervical cancer is reported here. In this study, patients with residual cancer underwent laparotomy eight weeks after one or two different radiotherapy protocols. Sixty-eight percent of patients underwent radical surgery, 85% of patients pelvic exenterations, and 15% radical hysterectomies. In 27% of patients, no evidence of residual cancer was found in surgical specimens. Radical surgery was well tolerated, and one-third of patients were free of disease for one year or more. Control of disease was obtained in 50% of pelvic exenterations and in 60% of radical hysterectomies, regardless of prognosis, clinical stage or radiotherapy scheme. Although results show an improvement of up to 22% when comparing this to other more conventional treatments, we have concluded that we must obtain a wider experience in order to support our findings.

    Neoadjuvant chemoradiotherapy has become the standard treatment for locally advanced rectal cancer. Neoadjuvant chemoradiotherapy not only can reduce tumor size and recurrence, but also increase the tumor resection rate and anus retention rate with very slight side effect. Comparing with preoperative chemotherapy, preoperative chemoradiotherapy can further reduce the local recurrence rate and downstage. Middle and low rectal cancers can benefit more from neoadjuvant chemradiotherapy than high rectal cancer. It needs to refine the selection of appropriate patients and irradiation modes for neoadjuvant chemoradiotherapy. Different therapeutic reactions to neoadjuvant chemoradiotherapy affect the type of surgical techniques, hence calling for the need of much attention. Furthermore, many problems such as accurate staging before surgery, selection of suitable neoadjuvant chemoradiotherapy method, and sensitivity prediction to preoperative radiotherapy need to be well settled.

    Purpose Cancer treatments are frequently associated with adverse effects, but there may be a cultural reluctance by care providers to be forthcoming with patients regarding these risks for fear of promoting nonadherence. Conversely, research in a number of countries indicates high levels of patient desire for this information. We sought to explore cancer patient experiences, satisfaction, and preferences for medication risk communication in a Middle East care setting. Methods We developed and administered a ten-item questionnaire (Arabic and English) to a convenience sample of consenting adult patients receiving treatment at the National Center for Cancer Care and Research in Qatar. Results One hundred and forty-three patients were interviewed. Most (88%) stated that the level of side effect information they received was sufficient, with physicians (86%) followed by pharmacists (39%) as the preferred sources. The majority (97%) agreed that knowing about possible side effects would help them recognize and manage the reaction, and 92% agreed that it would help them understand how to minimize or prevent the risks. Eighteen percent indicated that this information would make them not want to take treatment. Two-thirds (65%) had previously experienced intolerance to their cancer treatment regimen. Conclusion Most patients surveyed expressed preference for the details of possible side effects they may encounter in their treatment. However, one in five considered such information a factor for nonadherence, indicating the need for patient-specific approaches when communicating medication risks. PMID:27175061

    Based upon studies from randomized clinical trials, the extended (D2) lymph node dissection is now recommended as a standard procedure for local advanced gastric cancer worldwide. However, the rational extent lymphadenectomy for local advanced gastric cancer has remained a topic of debate in the past decades. Due to the limitation of low metastatic rate in para-aortic nodes (PAN) in JCOG9501, the clinical benefit of D2+ para-aortic nodal dissection (PAND) for patients with stage T4 and/or stage N3 disease, which is very common in China and other countries except Japan and Korea, cannot be determined. Furthermore, the role of splenectomy for complete resection of No.10 and No.11 nodes has been controversial, and however, the final results from the randomized trial of JCOG0110 have yet to be completed. Gastric cancer with the No.14 and No.13 lymph node metastasis is defined as M1 stage in the current version of the Japanese classification. We propose that D2+No.14v and +No.13 lymphadenectomy may be an option in a potentially curative gastrectomy for tumors with apparent metastasis to the No.6 nodes or infiltrate to duodenum. The examined lymph node and extranodal metastasis are significantly associated with the survival of gastric cancer patients. PMID:27647967

    2015-01-01

    To date a variety of non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) mouse models have been developed that mimic human lung cancer. Chemically induced or spontaneous lung cancer in susceptible inbred strains has been widely used, but the more recent genetically engineered somatic mouse models recapitulate much better the genotype-phenotype correlations found in human lung cancer. Additionally, improved orthotopic transplantation of primary human cancer tissue fragments or cells into lungs of immune-compromised mice can be valuable tools for preclinical research such as antitumor drug tests. Here we give a short overview of most somatic mouse models for lung cancer that are currently in use. We accompany each different model with a description of its practical use and application for all major lung tumor types, as well as the intratracheal injection or direct injection of fresh or freeze-thawed tumor cells or tumor cell lines into lung parenchyma of recipient mice. All here presented somatic mouse models are based on the ability to (in) activate specific alleles at a time, and in a tissue-specific cell type, of choice. This spatial-temporal controlled induction of genetic lesions allows the selective introduction of main genetic lesions in an adult mouse lung as found in human lung cancer. The resulting conditional somatic mouse models can be used as versatile powerful tools in basic lung cancer research and preclinical translational studies alike. These distinctively advanced lung cancer models permit us to investigate initiation (cell of origin) and progression of lung cancer, along with response and resistance to drug therapy. Cre/lox or FLP/frt recombinase-mediated methods are now well-used techniques to develop tissue-restricted lung cancer in mice with tumor-suppressor gene and/or oncogene (in)activation. Intranasal or intratracheal administration of engineered adenovirus-Cre or lentivirus-Cre has been optimized for introducing Cre

  17. Clinical trials update: Medical management of advanced breast cancer.

    PubMed

    Major, Maureen A

    2003-12-01

    Selection of treatment for metastatic breast cancer depends on several factors: the status of estrogen receptors or progesterone receptors on breast cancer cells and the expression levels of human epidermal growth factor receptor-2. The presence of estrogen or progesterone receptors typically indicates slower-growing tumors that may be amenable to hormonal manipulation, which provides significant disease control while offering a better toxicity profile than conventional chemotherapy. The understanding of hormonal therapies in patients with postmenopausal metastatic breast cancer has advanced greatly in the past several decades. Aromatase inhibitors, although used initially as second-line therapy, recently have proved to be as effective as tamoxifen, if not superior to it, as first-line therapy for metastatic breast cancer. New data also suggest that letrozole provides significantly better objective responses than anastrozole as second-line therapy. Exemestane, a steroidal aromatase inhibitor, is an effective third-line therapy. Fulvestrant, an estrogen receptor antagonist with no known agonist effect, provides a new option for hormonal therapy. For patients with metastatic breast cancer and overexpression of human epidermal growth factor receptor-2 on tumor cells, the monoclonal antibody trastuzumab is the preferred option, either in combination with paclitaxel as first-line treatment, or as a single agent for second-line therapy. By extending the sequence of hormonal therapy, disease progression and the need for chemotherapy may be significantly delayed, potentially extending patient survival rates and improving quality of life.

    2011-01-01

    Despite the recent trend toward a slight decrease in age-adjusted cancer mortality in some countries, crude mortality rates will continue to increase, driven by the demographic shift towards an aged population. Small molecules (small molecules and biologics) are not only a new therapeutic acquisition, but the tools of a more fundamental transition: the transformation of cancer from a rapidly fatal disease into a chronic condition. Antibodies and cancer vaccines can be used for a long time, even beyond progressive disease, and in aged patients, usually unfit for more aggressive conventional treatments. However, this transition to chronicity will require novel developmental guidelines adequate to this kind of drugs, for which optimal dose is not usually the maximal tolerated dose, pharmacokinetics does not define treatment schedule, and tumor shrinkage is not a good correlate of survival. The ongoing cancer immunotherapy program (including several monoclonal antibodies and therapeutic vaccines) at the Centre of Molecular Immunology can illustrate the issues to be addressed, both biological and social, along the path to transform advanced cancer into a chronic non-communicable disease compatible with years of quality life.

    The first St Gallen Advanced Prostate Cancer Consensus Conference (APCCC) Expert Panel identified and reviewed the available evidence for the ten most important areas of controversy in advanced prostate cancer (APC) management. The successful registration of several drugs for castration-resistant prostate cancer and the recent studies of chemo-hormonal therapy in men with castration-naïve prostate cancer have led to considerable uncertainty as to the best treatment choices, sequence of treatment options and appropriate patient selection. Management recommendations based on expert opinion, and not based on a critical review of the available evidence, are presented. The various recommendations carried differing degrees of support, as reflected in the wording of the article text and in the detailed voting results recorded in supplementary Material, available at Annals of Oncology online. Detailed decisions on treatment as always will involve consideration of disease extent and location, prior treatments, host factors, patient preferences as well as logistical and economic constraints. Inclusion of men with APC in clinical trials should be encouraged. PMID:26041764

    Inhibition of epidermal growth factor receptor (EGFR) has become an important target in the treatment of advanced non-small cell lung cancer (NSCLC). Erlotinib and gefitinib, two small molecular agents that target the tyrosine kinase domain of the EGFR, were approved in many countries for the treatment of locally advanced or metastatic NSCLC as a second- or third-line regimen. Since then, randomized trials have evaluated the role of these two targeted agents alone or combined with chemotherapy in maintenance and first-line settings. This review summarizes the results of recent clinical trials with these tyrosine kinase inhibitors, with a focus on erlotinib, as first-line treatment towards a form of personalized medicine aimed at improving clinical outcome in advanced NSCLC.

    The goals of any cervical cancer prevention program should be threefold: to achieve high coverage of the population at risk, to screen women with an accurate test as part of high-quality services, and to ensure that women with positive test results are properly managed. This article focuses on the experiences of the Alliance for Cervical Cancer Prevention (ACCP) in delivery of screening and treatment services as part of cervical cancer prevention projects in Africa, Latin America, and Asia. Research and experience show that cervical cancer can be prevented when strategies and services are well planned and well managed and when attention is paid to program monitoring and evaluation. Coordination of program components, reduction of the number of visits, improvement of service quality, and flexibility in how services are delivered are all essential features of an effective service.

    Objectives: The purpose of this study is to report a case series of advanced cancer patients whose cancer pain was relieved by using autonomic nerve pharmacopuncture (ANP) treatment. ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP) along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae) to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases) with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12 ─ 20 mL injection) of each patient’s dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS) for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain. PMID:25780711

    Oncolytic viruses are multifunctional anticancer agents with huge clinical potential, and have recently passed the randomized Phase III clinical trial hurdle. Both wild-type and engineered viruses have been selected for targeting of specific cancers, to elicit cytotoxicity, and also to generate antitumor immunity. Single-agent oncolytic virotherapy treatments have resulted in modest effects in the clinic. There is increasing interest in their combination with cytotoxic agents, radiotherapy and immune-checkpoint inhibitors. Similarly to oncolytic viruses, the benefits of chemotherapeutic agents may be that they induce systemic antitumor immunity through the induction of immunogenic cell death of cancer cells. Combining these two treatment modalities has to date resulted in significant potential in vitro and in vivo synergies through various mechanisms without any apparent additional toxicities. Chemotherapy has been and will continue to be integral to the management of advanced cancers. This review therefore focuses on the potential for a number of common cytotoxic agents to be combined with clinically relevant oncolytic viruses. In many cases, this combined approach has already advanced to the clinical trial arena.

    Purpose To provide a review of the clinical data, controversies, and limitations that underpin current recommendations for approaches to larynx preservation for locally advanced larynx cancer requiring total laryngectomy. Methods The key findings from pivotal randomized controlled trials are discussed, including quality of life, late effects, and function assessments. Trials investigating taxane inclusion in induction chemotherapy and trials of epidermal growth factor receptor inhibition for radiosensitization are put into perspective for larynx cancer. Controversies in the management of T4 primaries and the opportunities for conservation laryngeal surgery are reviewed. Results There are data from clinical trials to support induction chemotherapy, followed by radiotherapy (preferred approach in Europe) and concomitant cisplatin plus radiotherapy (preferred in North America) for nonsurgical preservation of the larynx. Treatment intensification by a sequential approach of induction, followed by concomitant treatment, is investigational. Transoral laryngeal microsurgery and transoral robotic partial laryngectomy have application in selected patients. Conclusion The management of locally advanced larynx cancer is challenging and requires an experienced multidisciplinary team for initial evaluation, response assessment, and support during and after treatment to achieve optimal function, quality of life, and overall survival. Patient expectations, in addition to tumor extent, pretreatment laryngeal function, and coexisting chronic disease, are critical factors in selecting surgical or nonsurgical primary treatment.

    The striking prevalence of HIV, TB and malaria, as well as outbreaks of emerging infectious diseases, such as influenza A (H7N9), Ebola and MERS, poses great challenges for patient care in resource-limited settings (RLS). However, advanced diagnostic technologies cannot be implemented in RLS largely due to economic constraints. Simple and inexpensive point-of-care (POC) diagnostics, which rely less on environmental context and operator training, have thus been extensively studied to achieve early diagnosis and treatment monitoring in non-laboratory settings. Despite great input from material science, biomedical engineering and nanotechnology for developing POC diagnostics, significant technical challenges are yet to be overcome. Summarized here are the technical challenges associated with POC diagnostics from a RLS perspective and the latest advances in addressing these challenges are reviewed.

    Pancreatic adenocarcinoma ranks as the fourth most common cause of cancer death in the USA. Patients usually present late with advanced disease, limiting attempted curative surgery to 10% of cases. Overall prognosis is poor with one-year survival rates of less than 10% with palliative chemotherapy and/or radiotherapy. Given these dismal results, a minimally invasive treatment capable of local destruction of tumor tissue with low morbidity may have a place in the treatment of this disease. In this paper we review the preclinical photodynamic therapy (PDT) studies which have shown that it is possible to achieve a zone of necrosis in normal pancreas and implanted tumour tissue. Side effects of treatment and evidence of a potential survival advantage are discussed. We describe the only published clinical study of pancreatic interstitial PDT, which was carried out by our group (Bown et al Gut 2002), in 16 patients with unresectable locally advanced pancreatic adenocarcinoma. All patients had evidence of tumor necrosis on follow-up imaging, with a median survival from diagnosis of 12.5 months. Finally, we outline a phase I dose-escalation study of verteporfin single fibre PDT followed by standard gemcitabine chemotherapy which our group is currently undertaking in patients with locally advanced pancreatic cancer. Randomized controlled studies are also planned.

    Prostate cancer is the most common malignancy in men worldwide. The rate of patients presenting with locally advanced prostate cancer has declined in recent decades, mainly due to prostate-specific antigen screening, but the management of these patients still remains controversial. Current literature suggests that the standard of care for these patients is a combination approach with radiation therapy and androgen deprivation therapy. However, there remain many unresolved issues, including the role of dose-escalated radiation therapy, the additional benefit of surgery and the role of systemic therapy, both standard chemotherapeutic agents and novel agents. Furthermore, in the era of personalised medicine, additional research is needed to evaluate the role of biomarkers to better predict the risk of local and systemic relapse in this population.

    Patient satisfaction with cancer immunotherapy, which is not covered by health insurance in Japan, was evaluated among 65 patients with advanced cancer who had received immunotherapy in our hospital for 2 years. Satisfaction measures were based on patients' expectations for medical care, cost, and staff services, and involved a questionnaire consisting of 25 items. Results of the questionnaire analysis showed that most patients, who expected much of antigen-specific vaccination such as dendritic cells (DC) pulsed tumor-associated antigens, were dissatisfied with the high cost of private immunotherapy(i. e., not covered by medical insurance), and were unable to perceive the effectiveness of the treatment because there was no quantitative analysis of killer T cells induced by immunotherapy. Therefore, it is critically important for us to confirm the safety and efficiency of cancer immunotherapy, before introducing medical insurance for cancer patients in Japan. In addition, the quantitative measurement of killer T cells induced by DC peptide vaccines should be considered, to meet patients' expectations.

    Rectal cancer accounts for a relevant part of colorectal cancer cases, with a mortality of 4-10/100000 per year. The development of locoregional recurrences and the occurrence of distant metastases both influences the prognosis of these patients. In the last two decades, new multimodality strategies have improved the prognosis of locally advanced rectal cancer with a significant reduction of local relapse and an increase in terms of overall survival. Radical surgery still remains the principal curative treatment and the introduction of total mesorectal excision has significantly achieved a reduction in terms of local recurrence rates. The employment of neoadjuvant treatment, delivered before surgery, also achieved an improved local control and an increased sphincter preservation rate in low-lying tumors, with an acceptable acute and late toxicity. This review describes the multidisciplinary management of rectal cancer, focusing on the effectiveness of neoadjuvant chemoradiotherapy and of post-operative adjuvant chemotherapy both in the standard combined modality treatment programs and in the ongoing research to improve these regimens.

    Purpose: Patients with nonmetastatic locally advanced unresectable pancreatic cancer have a dismal prognosis. Conventional concurrent chemoradiotherapy requires 6 weeks of daily treatment and can be arduous. We explored the safety and effectiveness of a 3-day course of hypofractionated stereotactic body radiotherapy (SBRT) followed by gemcitabine in this population. Patients and Methods: A total of 36 patients with nonmetastatic, locally advanced, unresectable pancreatic cancer with {>=}12 months of follow-up were included. They received three fractions of 8, 10, or 12 Gy (total dose, 24-36 Gy) of SBRT according to the tumor location in relation to the stomach and duodenum, using fiducial-based respiratory motion tracking on a robotic radiosurgery system. The patients were then offered gemcitabine for 6 months or until tolerance or disease progression. Results: With an overall median follow-up of 24 months (range, 12-33), the local control rate was 78%, the median overall survival time was 14.3 months, the median carbohydrate antigen 19-9-determined progression-free survival time was 7.9 months, and the median computed tomography-determined progression-free survival time was 9.6 months. Of the 36 patients, 28 (78%) eventually developed distant metastases. Six patients (17%) were free of progression at the last follow-up visit (range, 13-30 months) as determined by normalized tumor markers with stable computed tomography findings. Nine Grade 2 (25%) and five Grade 3 (14%) toxicities attributable to SBRT occurred. Conclusion: Hypofractionated SBRT can be delivered quickly and effectively in patients with nonmetastatic, locally advanced, unresectable pancreatic cancer with acceptable side effects and minimal interference with gemcitabine chemotherapy.

    According to d'Amico's criteria, high-risk localized prostate cancer are defined either by an extracapsular extension (T3 or T4), either by a high Gleason score (> 7) or a PSA rate higher than 20 ng/ml. Pelvic lymph node involvement also corresponds to locally advanced prostate cancer. Statistical models called nomograms have been developed to predict the probability of prostate cancer recurrence and are also used to define locally advanced patients. Prostate MRI may help to detect an extracapsular extension or a seminal vesicles involvement but remains still discussed. A bone scan, an abdominal and pelvic CT scan have to be performed in order to detect metastases. A pelvic lymph node dissection is recommended in order to adapt the treatment of these patients. Standard treatment for high-risk localized prostate cancer without lymph node involvement is now well defined. The association of both local radiation and a long androgen deprivation (GnHR agonist) showed an overall survival benefit (more than 10%). The radiation dose of 74 Gy is recommended. Other questions are still debating : the optimal duration of the hormonotherapy , the use of the bicalutamide 150 mg instead of GnRH agonists, the optimal radiation dose. Radical prostatectomy is no more considered as a standard treatment for these patients. Since the use of chemotherapy for metastatic patients showed a benefit in overall survival, the place of chemotherapy as adjuvant or neo-adjuvant treatment is questionned in several randomized phase III studies. Sometimes high-risk disease is diagnosed after performance of a radical prostatectomy. A postoperative radiation may be performed in order to decrease clinical and biochemical progression. The use of bicalutamide 150 mg in this situation may have a positive impact too on progression free survival. In case of lymph node involvement, androgen deprivation is the standard treatment with an overall survival benefit. The place of local radiation therapy is still

    Medical record documentation of cancer inpatients is a core component of continuity of care. The main goal of the study was an assessment of medical record documentation in a palliative care unit (PCU) using a targeted clinical audit based on deceased inpatients' charts. Stage 1 (2010): a clinical audit of medical record documentation assessed by a list of items (diagnosis, prognosis, treatment, power of attorney directive, advance directives). Stage 2 (2011): corrective measures. Stage 3 (2012): re-assessment with the same items' list after six month. Forty cases were investigated during stage 1 and 3. After the corrective measures, inpatient's medical record documentation was significantly improved, including for diagnosis (P = 0.01), diseases extension and treatment (P < 0.001). Our results highlighted the persistence of a weak rate of medical record documentation for advanced directives (P = 0.145).

    Dendrimers possess discrete highly compact nanostructures constituted of successive branched layers. Soon after the inception of dendrimers, recognition of their tunable structures and biologically favorable properties provoked a great enthusiasm in delving deeply into the utility of dendrimers for biomedical and pharmaceutical applications. One of the most important nanotechnology applications is the development of nanomedicines for targeted cancer therapies. Tremendous success in targeted therapies has been achieved with the use of dendrimer-based nanomedicines. This article provides a concise review on latest advances in the utility of dendrimers in immunotherapies and hormone therapies. PMID:26706410

    The purpose of this study was to observe the effects of autonomic nerve pharmacopuncture (ANP) treatment on cancer-related fatigue (CRF) in patients with advanced cancer. This observational case study was conducted at the East West Cancer Center of Daejeon University's Dunsan Korean Medical Hospital. Two patients were observed. One patient was diagnosed with left thymic cancer metastatic to the left pleura. The other patient had terminal-stage cervical cancer with iliac bone and lumbar 5 metastases. We injected mountain ginseng pharmacopuncture (MGP) into acupoints alongside the spine (Hua-Tuo-Jia-Ji-Xue, EX B2). We examined the patients for CRF using the Korean version of the Revised Piper Fatigue Scale (RPFS-K), which is a self-assessment tool. The scores on the RPFS-K for both patients tended to decrease during the treatment. Laboratory findings, including hematological changes, were also checked. Liver and renal function tests showed that the treatment was safe. Although further large-population studies are necessary, this case study suggests that ANP has a favorable effect on CRF in patients with advanced cancer.

    If androgen deprivation, chemical with LH-RH analogs or surgical with bilateral orchiectomy, still remains the stone edge of treatment of prostate cancer, in the metastatic setting, this hormonosensitivity, most of the time long, finally move on in hormonal-failure. If rare changes in the therapeutic strategy have been achieved in this setting since 2004 and the arrival of docetaxel, it is the global perception of the disease that has been modified and the definition of one specific entity: the castrate-resistant prostate cancer. This new definition and the changes of design and end-points of clinical trials testing new agents with strong recruitment during the past years have conducted to a real revolution in the management of castrate-refractory prostate cancer. The place of secondary hormonal manipulations, such as withdrawal of the anti-androgen, oestrogen or ketoconazole, still exists for a selected group of patients. In case of aggressive disease and symptoms, chemotherapy should be selected, docetaxel, in a three weeks schedule, and may be combined with Estracyt. It is time to consider the revolution of the post-chemotherapy setting with the arrival of two new drugs ; a cytotoxic one, the cabazitaxel and hormonal for the second one, the abiraterone acetate. The place of the immunotherapy with the sipuleucel-T may be more difficult to precise, especially in Europe, even if it has been finally indicated in the United States in the metastatic setting. Concerning bone metastasis, zoledronic acid was during a long time the only bone-targeted agent, effective in reducing the incidence of skeletal related events, and was recently exceeded by the denosumab, an anti-RANK ligand. Finally, let us hope that other changes will be achieved in the near future, with the cabazitaxel-docetaxel confrontation in the first-line setting, and the introduction of the abiraterone acetate before chemotherapy with docetaxel, already tested in ongoing trials.

    Planetary science is a field that evolves rapidly, motivated by spacecraft mission results. Exciting new mission results are generally communicated rather quickly to the public in the form of press releases and news stories, but it can take several years for new advances to work their way into college textbooks. Yet it is important for students to have exposure to these new advances for a number of reasons. In some cases, new work renders older textbook knowledge incorrect or incomplete. In some cases, new discoveries make it possible to emphasize older textbook knowledge in a new way. In all cases, new advances provide exciting and accessible examples of the scientific process in action. To bridge the gap between textbooks and new advances in planetary sciences we have developed content on new discoveries for use by undergraduate instructors. Called 'Discoveries in Planetary Sciences', each new discovery is summarized in a 3-slide PowerPoint presentation. The first slide describes the discovery, the second slide discusses the underlying planetary science concepts, and the third presents the big picture implications of the discovery. A fourth slide includes links to associated press releases, images, and primary sources. This effort is generously sponsored by the Division for Planetary Sciences of the American Astronomical Society, and the slide sets are available at http://dps.aas.org/education/dpsdisc/. Sixteen slide sets have been released so far covering topics spanning all sub-disciplines of planetary science. Results from the following spacecraft missions have been highlighted: MESSENGER, the Spirit and Opportunity rovers, Cassini, LCROSS, EPOXI, Chandrayan, Mars Reconnaissance Orbiter, Mars Express, and Venus Express. Additionally, new results from Earth-orbiting and ground-based observing platforms and programs such as Hubble, Keck, IRTF, the Catalina Sky Survey, HARPS, MEarth, Spitzer, and amateur astronomers have been highlighted. 4-5 new slide sets are

    The data on 912 patients with early cancer and 1245 with advanced cancer who were seen between 1971 and 1990 were compared. The incidence of undifferentiated-type cancer increased significantly in patients with advanced gastric cancer, but not in patients with early gastric cancer. When the histological types were compared with regard to sex, age and location in patients with early gastric cancer the undifferentiated type was found to increase only in males, while in patients with advanced gastric cancer the undifferentiated type increased in both sexes as well as in younger patients and in both the upper and middle third of the stomach. These differences in the trends between early and advanced cancers are probably due to the different degrees of diagnostic accuracy for the early detection of histological types. PMID:7640228

    A MESSAGE FROM ASCO's PRESIDENT For the second consecutive year, the American Society of Clinical Oncology (ASCO) is publishing Clinical Cancer Advances: Major Research Advances in Cancer Treatment, Prevention, and Screening, an annual review of the most significant cancer research presented or published over the past year. ASCO developed this report to demonstrate the enormous progress being made on the front lines of cancer research today. The report is intended to give all those with an interest in cancer care-the general public, cancer patients and physicians, policymakers, oncologists, and other medical professionals-an accessible summary of the year's most important cancer research advances. These pages report on new targeted therapies that are improving survival and response rates in hard-to-treat cancers such as kidney cancer, HER-2-positive breast cancer, head and neck cancer, and chronic myelogenous leukemia; the FDA's approval of the world's first preventive vaccine for human papillomavirus (HPV), which has the potential to dramatically reduce the global burden of cervical cancer; and advances in the fast-growing field of personalized medicine, including a new lung cancer test that could help physicians better target treatments and predict prognosis. These advances are only part of the landscape. Survival rates are on the rise, the number of cancer deaths in the United States began declining for the first time since 1930, and new research is showing that the rates of certain common cancers, such as those of the breast and colon, have stabilized, and may have even begun to decline. However, cancer research still faces a number of major obstacles. At a time of extraordinary scientific potential, declining federal funding of cancer research threatens to stall or even reverse recent progress. Such funding cuts have already led to fewer clinical trials, fewer talented young physicians entering the field, and a growing bottleneck of basic science discoveries

    The year 2015 marks the 30th anniversary of the publication of NSABP-R01, a landmark trial demonstrating the benefit of adding pelvic radiation to the treatment regimen for locally advanced rectal cancer with a resultant decrease in local recurrence from 25% to 16%. These results ushered in the era of multimodal therapy for rectal cancer, heralding modern treatment and changing the standard of care in the United States. We have seen many advances over the past 3 decades, including optimization of the administration and timing of radiation, widespread adoption of total mesorectal excision (TME), and the implementation of more effective systemic chemotherapy. The current standard is neoadjuvant chemoradiation with 5-fluorouracil (5-FU) and a radiosensitizer, TME, and adjuvant chemotherapy including 5-FU and oxaliplatin. The results of this regimen have been impressive, with a reported local recurrence rate of less than 10%. However, the rates of distant relapse remain 30% to 40%, indicating room for improvement. In addition, trimodality therapy is arduous and many patients are unable to complete the full course of treatment. In this article we discuss the current standard of care and alternative strategies that have evolved in an attempt to individualize therapy according to risk of recurrence.

    Prognostication is a critical medical task for the adequacy of treatment and management of priorities and expectations of patients and families. In 2005, the European Association of Palliative Care (EAPC) published recommendations on the formulation of vital prognosis in advanced cancer patients. The aim of this study is to analyze the literature subsequent to this review and to update the presented recommendations. Using the same strategy of the EAPC group, we performed a systematic literature search in the electronic databases PubMed and Scopus, which included original studies in adults with advanced cancer, without tumor-directed treatment, with a median survival of less than 90 days. The articles were analyzed and classified according to the level of evidence by two independent reviewers. The 41 articles analyzed allowed to keep grade A recommendations for clinical estimation of survival and Palliative Prognostic score and now also for Palliative Prognostic Index, performance status, dyspnea, lymphopenia and lactate dehydrogenase. Recommendations regarding the use of C-reactive protein, leukocytosis, azotemia, hypoalbuminemia and male gender as predictors reached grade B. To formulate the vital prognosis and to communicate it properly to the patient and family are core competencies of physicians, particularly of those who deal with end of life patients. The clinical impression combined with scientific evidence allows us to estimate more accurately the survival, allowing prioritizing and managing more appropriately the existing resources.

    Currently, there is no validated therapeutic target for biliary tract cancer (BTC). This study aimed to investigate the pre-clinical and clinical implication of HER2 as a therapeutic target in BTC. We established two novel HER2-amplified BTC cell lines, SNU-2670 and SNU-2773, from gallbladder cancer patients. SNU-2670 and SNU-2773 cells were sensitive to trastuzumab, dacomitinib, and afatinib compared with nine HER2-negative BTC cell lines. Dacomitinib and afatinib led to G1 cell cycle arrest in SNU-2773 cells and apoptosis in SNU-2670 cells. Furthermore, dacomitinib, afatinib, and trastuzumab showed synergistic cytotoxicity when combined with some cytotoxic drugs including gemcitabine, cisplatin, paclitaxel, and 5-fluorouracil. In a SNU-2670 mouse xenograft model, trastuzumab demonstrated a good anti-tumor effect as a monotherapy and in combination with gemcitabine increasing apoptosis. In our clinical data, 13.0% of patients with advanced BTC were defined as HER2-positive. Of these, three patients completed HER2-targeted chemotherapy. Two of them demonstrated a partial response, and the other one showed stable disease for 18 weeks. In summary, these pre-clinical and clinical data suggest that HER2 could be a therapeutic target, and that a HER2-targeting strategy should be developed further in patients with HER2-positive advanced BTC.

    The epidemiologic pattern of cancers in developing countries differs in many aspects from that of industrialized nations. Cancer natural history, microbiologic environment, patient's immune system, and drug availability may differ as well. Four of five new cases of cervical cancer and most of cervical cancer deaths occur in developing countries. Where chemoradiation and supportive care facilities are unavailable, it would be logical to consider an inexpensive effective drug. In locally advanced cases, neoadjuvant chemotherapy followed by surgery should be considered the treatment of choice. For ovarian cancer, it may be reasonable to maintain a secure supply of platinum and/or taxanes. For endometrial cancer, platinum compounds are proved active chemotherapic single agents. Oral medroxyprogesterone acetate (MPA) may represent a good chance for treating an advanced or recurrent disease. For vulvar/vaginal cancer, the role of chemotherapy alone is currently considered limited, and it is mostly used as palliative treatment in advanced or recurrent cases. Whenever possible, standard western chemotherapic regimens should be applied in developing countries as well. When standard therapies are unavailable, drugs of choice should be easily accessible, inexpensive, and effective. The most commonly used drugs are cisplatin, cyclophosphamide, and MPA.

    Illness is constituted by subjective experiences of symptoms and their psychosocial consequences. Illness perceptions concern people's lay beliefs about understandings and interpretation of a disease and expectations as to disease outcome. Our knowledge about illness perceptions and coping in relation to the cancer care context among persons with colorectal cancer (CRC) and their partners is incomplete. The aim of the present study was to explore illness perceptions in relation to contemporary cancer care settings among CRC survivors and partners. The present research focused on illness rather than disease, implying that personal experiences are central to the methodology. The grounded theory method used is that presented by Kathy Charmaz. The present results explore illness perceptions in the early recovery phase after being diagnosed and treated for cancer in a contemporary cancer care setting. The core category outlook on the cancer diagnosis when quickly informed, treated, and discharged illustrates the illness perceptions of survivors and partners as well as the environment in which they were found. The cancer care environment is presented in the conceptual category experiencing contemporary cancer care settings. Receiving treatment quickly and without waiting was a positive experience for both partners and survivors; however partners experienced the information as massive and as causing concern. The period after discharge was being marked by uncertainty and loneliness, and partners tended to experience non-continuity in care as more problematic than the survivor did. The results showed different illness perceptions and a mismatch between illness perceptions among survivors and partners, presented in the conceptual category outlook on the cancer diagnosis. One illness perception, here presented among partners, focused on seeing the cancer diagnosis as a permanent life-changing event. The other illness perception, here presented among survivors, concentrated on

    Background The majority of differentiated thyroid cancer tends to present with limited locoregional disease, leading to excellent long-term survival after operative treatment. Even patients with advanced local disease may survive for long periods with appropriate treatment. The aim of this study is to present our institutional experience of the management of locally advanced differentiated thyroid cancer and to analyze factors predictive of outcome. Methods We reviewed our institutional database of 3,664 previously untreated patients with differentiated thyroid cancer operated between 1986 and 2010. A total of 153 patients had tumor extension beyond the thyroid capsule that invaded the subcutaneous soft tissues, recurrent laryngeal nerve, larynx, trachea, or esophagus. Details on extent of operation and adjuvant therapy were recorded. Disease-specific survival and locoregional recurrence-free probability were determined by the Kaplan-Meier method. Factors predictive of outcome were determined by multivariate analysis. Results The median age of the 153 patients with tumor extension beyond the thyroid capsule was 55 years (range 11–91 years). Eighty-nine patients (58.2%) were female. Twenty-three patients (15.0%) were staged as M1 at presentation, and 122 (79.7%) had pathologically involved lymph nodes. The most common site of extrathyroidal extension was the recurrent laryngeal nerve (51.0%) followed by the trachea (46.4%) and esophagus (39.2%). Sixty-three patients (41%) required resection of the recurrent laryngeal nerve due to tumor involvement. After surgery, 20 patients (13.0%) had gross residual disease (R2), 63 (41.2%) had a positive margin of resection (R1), and 70 (45.8%) had complete resection with negative margins (R0). With a median follow-up of 63.9 months, 5-year, disease-specific survival, when stratified by R0/R1/R2 resection, was 94.4%, 87.6%, and 67.9%, respectively (P = .030). The data do not demonstrate a statistical difference in survival

    A 70-year-old man was referred to our hospital with ascending colon cancer (cT3N1M0, Stage IIIa), which was found during examinations following a positive fecal occult blood test. The patient was also diagnosed with early gastric cancer (cT1a, N0, M0, Stage IA)during a preoperative gastroscopy examination. A laparoscopically assisted right colectomy and D3 lymphadenectomy was performed for the ascending colon cancer. The postoperative pathological diagnosis was Stage IIIb (pT3N2), he was administered in combination with capecitabine plus oxaliplatin (CapeOX) as adjuvant chemotherapy before the treatment for the colon cancer. After 6 months of adjuvant chemotherapy, we were unable to detect any gastric lesions at the same location using gastroscopy, and so diagnosed a clinical complete response. A follow-up gastroscopy 6 months later showed the same findings. The patient has had no recurrence of gastric cancer for 18 months after the initial operation. He will continue to be followed up closely using gastroscopy. In this case, CapeOX as adjuvant chemotherapy for advanced colon cancer was also effective for early gastric cancer.

    The incidence of pancreatic ductal adenocarcinoma (PDA) is on the rise, and the prognosis is extremely poor because PDA is highly aggressive and notoriously difficult to treat. Although gemcitabine- or 5-fluorouracil-based chemotherapy is typically offered as a standard of care, most patients do not survive longer than 1 year. Therefore, the development of alternative therapeutic approaches for patients with PDA is imperative. As PDA cells express numerous tumor-associated antigens that are suitable vaccine targets, one promising treatment approach is cancer vaccines. During the last few decades, cell-based cancer vaccines have offered encouraging results in preclinical studies. Cell-based cancer vaccines are mainly generated by presenting whole tumor cells or dendritic cells to cells of the immune system. In particular, several clinical trials have explored cell-based cancer vaccines as a promising therapeutic approach for patients with PDA. Moreover, chemotherapy and cancer vaccines can synergize to result in increased efficacies in patients with PDA. In this review, we will discuss both the effect of cell-based cancer vaccines and advances in terms of future strategies of cancer vaccines for the treatment of PDA patients. PMID:27182156

    The aim of this study was to investigate the utility of pulmonary rehabilitation for improving of exercises efficiency, dyspnea, and quality of life of patients with lung cancer during chemotherapy. After the enrollment selection, the study included 20 patients with newly diagnosed advanced lung cancer and performance status 0-2. There were 12 patients randomly allocated to the pulmonary rehabilitation group and another 8 constituted the control group that did not undergo physical rehabilitation. Both groups of patients had continual cycles of chemotherapy. Data were analyzed before and after 8 weeks of physical rehabilitation, and before and after 8 weeks of observation without rehabilitation in controls. The inpatient rehabilitation program was based on exercise training with ski poles and respiratory muscle training. We found a tendency for enhanced mobility (6 Minute Walk Test: 527.3 ± 107.4 vs. 563.9 ±64.6 m; p > 0.05) and a significant increase in forced expired volume in 1 s (66.9 ± 13.2 vs. 78.4 ± 17.7 %predicted; p = 0.016), less dyspnea (p = 0.05), and a tendency for improvement in the general quality of life questionnaire after completion of pulmonary rehabilitation as compared with the control group. This report suggests that pulmonary rehabilitation in advanced lung cancer patients during chemotherapy is a beneficial intervention to reduce dyspnea and enhance the quality of life and mobility.

    The prostate cancer is one of the most often cancers amongst males. Its frequency is increasing with age. Thanks to widespread of screening denomination of specific prostate specific antigen (PSA), ultrasonography including the one in transrectal (TRUS), computed tomography, magnetic resonance and especially the awareness of society, the number of patients with low local advance of illness is increasing. The basic method of treatment in such cases is still the surgical removal of prostate with seminal bladder or radiotherapy. To this purpose tele-(IMRT, VMAT) or brachytherapy (J125, Ir192, Pa103) is used. In patients with higher risk of progression the radiotherapy may be associated with hormonotherapy (total androgen blockage-LH-RH analog and androgen). Despite numerous clinical researches conducted there is still no selection of optimal sequence of particular methods. Moreover, no explicit effectiveness was determined. The general rule of treatment in patients suffering from prostate cancer still remains individual selection of therapeutic treatment depending on the age of a patient, general condition and especially patient's general preferences. In case of elderly patients and patients with low risk of progression, recommendation of direct observation including systematical PSA denomination, clinical transrectal examination, TRUS, MR of smaller pelvis or scintigraphy of the whole skeleton may be considered.

    Nowadays, the standard management of advanced epithelial ovarian cancer is correct surgical staging and optimal tumour cytoreduction followed by platinum and taxane-based chemotherapy. Standard surgical staging consists of peritoneal washings, total hysterectomy, and bilateral salpingo-oophorectomy, inspection of all abdominal organs and the peritoneal surface, biopsies of suspicious areas or randomised biopsies if they are not present, omentectomy and para-aortic lymphadenectomy. After this complete surgical staging, the International Federation of Gynaecology and Obstetrics (FIGO) staging system for ovarian cancer is applied to determine the management and prognosis of the patient. Complete tumour cytoreduction has shown an improvement in survival. There are some criteria to predict cytoreduction outcomes based on serum biomarkers levels, preoperative imaging techniques, and laparoscopic-based scores. Optimised patient selection for primary cytoreduction would determine patients who could benefit from an optimal cytoreduction and might benefit from interval surgery. The administration of intraperitoneal chemotherapy after debulking surgery has shown an increase in progression-free survival and overall survival, especially in patients with no residual disease after surgery. It is considered that 3–17% of all epithelial ovarian carcinoma (EOC) occur in young women that have not fulfilled their reproductive desires. In these patients, fertility-sparing surgery is a worthy option in early ovarian cancer. PMID:27594911

    This study was conducted to report outcomes and identify factors predictive of survival and recurrence in patients undergoing lateral temporal bone resection (LTBR) as part of an extended radical parotidectomy for parotid cancer. This is a retrospective cohort study which includes all patients undergoing LTBR for parotid cancer between 1994 and 2010 at two affiliated academic centers. Survival and recurrence rates were analyzed using the Kaplan-Meier method and Cox multivariate regression. A total of 12 patients with median follow-up duration of 30.6 months were included: 6 de novo cases and 6 patients referred after local recurrence. Actuarial locoregional control at 2 years was 73%. Most patients (11; 92%) developed disease recurrence with distant metastases the most common site of first failure (83%). Overall and disease-specific survival rates were 80% at 2 years and 22.5% at 5 years. Recurrence-free survival (RFS) was 67% at 2 years and 8.3% at 5 years. On multivariate analysis, surgical margin status was an independent predictor of RFS (hazard ratio = 3.85, p = 0.045). In advanced parotid cancer, LTBR with a goal of gross total resection offers good locoregional control with an acceptable complication rate. The benefits of this surgery must be balanced with the morbidity and low likelihood of long-term survival, with most patients ultimately experiencing disease recurrence and death.

    To provide high-quality and effective cancer care, problems and unmet needs of family members during their relatives' hospitalisation have to be identified as well. The aims were to determine how needs of family members of patients with terminal cancer are met and to analyse factors that influence them. The needs were assessed with the Family Inventory of Needs. Each item (n = 20) represents one need of family members, for which the importance and satisfaction are rated. The study comprised 270 family members of hospitalised advanced cancer patients staying in the University Hospital Ostrava who were receiving palliative care. The family members preferred sufficient basic information and patient comfort. The unmet needs were support of hope (73%) and provision of information (65%). The unmet needs were more frequently identified by women, individuals with lower education, younger persons, unemployed, patients' children and family members of patients with generally unfavourable health status (P < 0.05). There was a correlation between lower quality of life and higher numbers of unmet needs. Targeted interventions aimed at meeting important needs of the family members may improve their quality of life.

    The treatment of a high risk case of an advanced thyroid cancer is reported. The patient had a thyroid cancer with metastatic lesions of the frontal bone, left temporal bone, left sacroiliac joint, lytic destruction of C6 and lytic lesion of C7. A pre-operative immobilization of the cervical spine was performed by a halo cast set on a corset of gypsum. After this, the patient underwent a thyroidectomy and, at the same time, a metallic plate was applied to immobilize C5-C7. A month after he underwent reoperative surgery to stabilize definitively the cervical spine. Subsequently he was treated by TCT and 131I subdivided in several cycles. The latest total body scan demonstrated a complete regression of secondary lesions.

    Non-small cell lung cancer (NSCLC) remains the most common cause of cancer-related death in the United States. Survival for patients with advanced disease remains meager with standard platinum-based doublet therapy even given initially. Improved efficacy and tolerability of third-generation chemotherapies and small-molecule inhibitors has prompted the evaluation of these agents in the maintenance setting in order to enhance current outcomes. Two separate strategies have evolved: the introduction of a non-cross-resistant drug immediately following first-line or induction chemotherapy (switch maintenance), or the continuation of the non-platinum partner initially introduced during induction (continuation maintenance). Here we review the available clinical trial data evaluating both maintenance strategies, and offer our assessment of their contemporary clinical implications and cost-effectiveness.

    Esophagogastric cancers (EGCa) are a leading cause of cancer related mortality worldwide. It has been recognized that they represent heterogenous diseases based on histology and anatomy. However, it is also increasingly evident that these are diverse malignancies based on genetic alterations, and this is increasingly making these diseases amenable to targeted therapies. While epidermal growth factor receptor (EGFR) and mTOR inhibitors have failed to prove effective in the treatment of advanced EGCa, vascular endothelial growth factor (VEGF) inihibitor have now been demonstrated to improve survival, at least in the 2nd line setting of adenocarcinomas. Other promising approaches are being investigated, including targeted therapies such as MET and FGFR inhibitors, as well as immunotherapy and agents that may affect synthetic lethality.

    In the past decade, molecular classification of cancer has gained high popularity owing to its high predictive power on clinical outcomes as compared with traditional methods commonly used in clinical practice. In particular, using gene expression profiles, recent studies have successfully identified a number of gene sets for the delineation of cancer subtypes that are associated with distinct prognosis. However, identification of such gene sets remains a laborious task due to the lack of tools with flexibility, integration and ease of use. To reduce the burden, we have developed an R package, CAsubtype, to efficiently identify gene sets predictive of cancer subtypes and clinical outcomes. By integrating more than 13,000 annotated gene sets, CAsubtype provides a comprehensive repertoire of candidates for new cancer subtype identification. For easy data access, CAsubtype further includes the gene expression and clinical data of more than 2000 cancer patients from TCGA. CAsubtype first employs principal component analysis to identify gene sets (from user-provided or package-integrated ones) with robust principal components representing significantly large variation between cancer samples. Based on these principal components, CAsubtype visualizes the sample distribution in low-dimensional space for better understanding of the distinction between samples and classifies samples into subgroups with prevalent clustering algorithms. Finally, CAsubtype performs survival analysis to compare the clinical outcomes between the identified subgroups, assessing their clinical value as potentially novel cancer subtypes. In conclusion, CAsubtype is a flexible and well-integrated tool in the R environment to identify gene sets for cancer subtype identification and clinical outcome prediction. Its simple R commands and comprehensive data sets enable efficient examination of the clinical value of any given gene set, thus facilitating hypothesis generating and testing in biological and

    Although physical treatments play a central role in cancer therapy, SI-traceable metrology has only been established for some of them. Several forms of treatment currently used (particularly intensity-modulated radiation therapy (IMRT), hadron therapy, high-intensity therapeutic ultrasound (HITU) and brachytherapy) suffer from the limited metrological support, which restricts the success of these techniques. Recognizing this deficit, the European Union identified metrology for health as one of the first four Targeted Programmes in the framework of the European Metrology Research Programme (EMRP) running from 2008 to 2011. This programme included two EMRP projects addressing metrology for cancer therapy: project T2.J06 dealing with brachytherapy project T2.J07 dealing with external beam cancer therapy using ionizing radiation and high-intensity therapeutic ultrasound. Primary measurement standards applicable to modern treatment conditions were developed under both projects, together with measurement techniques which are meant as a basis for future protocols for dosimetry, treatment planning and monitoring. In order to provide a platform for the presentation of current developments in clinical measurement techniques for cancer therapy, together with the achievements of both projects, an international Conference on Advanced Metrology for Cancer Therapy (CAMCT) was held from 29 November to 1 December 2011 at the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany. The main sessions of the conference: Primary and secondary standards of absorbed dose to water for IMRT and brachytherapy, 3D dose distributions and treatment planning for IMRT and brachytherapy, Hadron therapy (protons and carbon ions), High-intensity therapeutic ultrasound (HITU), were geared to the main foci of the projects. Metrologists and medical physicists from countries all over the world attended the conference and made it into a forum for the exchange of information and expertise

    Anorexia, or loss of appetite, is a troubling symptom for many patients with advanced cancer. The early observation that breast cancer patients, who were prescribed megestrol acetate as a cancer treatment, went on to increase their appetite and gain weight has given rise to a large number of clinical trials that have tested this progestational drug as a palliative agent for the cancer anorexia/weight loss syndrome. This review focuses on these trials, summarizing their findings and providing a practical approach for prescribing megestrol acetate to advanced cancer patients who suffer from the cancer anorexia/weight loss syndrome.

    Purpose We examined whether the survival advantage of androgen-deprivation therapy with radiotherapy (ADT plus RT) relative to ADT alone for men with locally advanced prostate cancer reported in two randomized trials holds in real-world clinical practice and extended the evidence to patients poorly represented in the trials. Methods We conducted nonrandomized effectiveness studies of ADT plus RT versus ADT in three groups of patients diagnosed between 1995 and 2007 and observed through 2009 in the SEER-Medicare data set: (1) the randomized clinical trial (RCT) cohort, which included men age 65 to 75 years and was most consistent with participants in the randomized trials; (2) the elderly cohort, which included men age > 75 years with locally advanced prostate cancer; and (3) the screen-detected cohort, which included men age ≥ 65 years with screen-detected high-risk prostate cancer. We evaluated cause-specific and all-cause mortality using propensity score, instrumental variable (IV), and sensitivity analyses. Results In the RCT cohort, ADT plus RT was associated with reduced cause-specific and all-cause mortality relative to ADT alone (cause-specific propensity score–adjusted hazard ratio [HR], 0.43; 95% CI, 0.37 to 0.49; all-cause propensity score–adjusted HR, 0.63; 95% CI, 0.59 to 0.67). Effectiveness estimates for the RCT cohort were not significantly different from those from randomized trials (P > .1). In the elderly and screen-detected cohorts, ADT plus RT was also associated with reduced cause-specific and all-cause mortality. IV analyses produced estimates similar to those from propensity score–adjusted methods. Conclusion Older men with locally advanced or screen-detected high-risk prostate cancer who receive ADT alone risk decrements in cause-specific and overall survival. PMID:25559808

    DNA focused panel sequencing has been rapidly adopted to assess therapeutic targets in advanced/refractory cancer. Integrated Genomic Profiling (IGP) utilising DNA/RNA with tumour/normal comparisons in a Clinical Laboratory Improvement Amendments (CLIA) compliant setting enables a single assay to provide: therapeutic target prioritisation, novel target discovery/application and comprehensive germline assessment. A prospective study in 35 advanced/refractory cancer patients was conducted using CLIA-compliant IGP. Feasibility was assessed by estimating time to results (TTR), prioritising/assigning putative therapeutic targets, assessing drug access, ascertaining germline alterations, and assessing patient preferences/perspectives on data use/reporting. Therapeutic targets were identified using biointelligence/pathway analyses and interpreted by a Genomic Tumour Board. Seventy-five percent of cases harboured 1-3 therapeutically targetable mutations/case (median 79 mutations of potential functional significance/case). Median time to CLIA-validated results was 116 days with CLIA-validation of targets achieved in 21/22 patients. IGP directed treatment was instituted in 13 patients utilising on/off label FDA approved drugs (n = 9), clinical trials (n = 3) and single patient IND (n = 1). Preliminary clinical efficacy was noted in five patients (two partial response, three stable disease). Although barriers to broader application exist, including the need for wider availability of therapies, IGP in a CLIA-framework is feasible and valuable in selection/prioritisation of anti-cancer therapeutic targets.

    Purpose: This was a retrospective observational study to elicit the outcome of the therapeutic strategy of concurrent neoadjuvant chemoradiotherapy protocol for locally advanced breast cancer. Methods and Materials: A large series of 1,117 consecutive cases of locally advanced breast cancer treated at the Cancer Institute (WIA), in Chennai, South India, between 1990 and 1999 and followed through 2004 formed the basis for this study. Disease-free survival was the main outcome, and nodal and tumor downstaging were the intermediate outcome measures studied. Results: Primary tumor downstaging was observed in 45% and nodal downstaging in 57.5%. The disease-free survival rate of nodal downstaged patients at 5, 10, and 15 years was 75%, 65%, and 58%, respectively. The corresponding rates for pre- and postoperative node-negative patients were 70%, 60%, and 59%. The best survival was seen among those who were tumor and node negative postoperatively. Nodal downstaging halved the risk of disease recurrence and death compared with node positivity, irrespective of tumor sterility. Conclusions: A randomized trial using cyclophosphamide, methotrexate, and 5-fluorouracil vs. an anthracycline-based regimen in the setting of concurrent chemoradiotherapy appears indicated. Additional preoperative chemotherapy to maximize nodal and tumor downstaging should be investigated. A change in postoperative chemotherapy according to nodal status could also be explored.

    Cancer related fatigue (CRF) is a common and debilitating symptom that can influence quality of life (QoL) in cancer patients. The increase in survival times stresses for a better understanding of how CRF affects patients' QoL. This was a cross-sectional descriptive study with 148 randomly recruited prostate cancer patients aiming to explore CRF and its impact on QoL. Assessments included the Cancer Fatigue Scale, EORTC QLQ-C30, and EORTC QLQ-PR25. Additionally, 15 in-depth structured interviews were performed. Quantitative data were analyzed with simple and multiple regression analysis and independent samples t-test. Qualitative data were analyzed with the use of thematic content analysis. The 66.9% of the patients experienced CRF with higher levels being recorded for the affective subscale. Statistically significant differences were found between the patients reporting CRF and lower levels of QoL (mean = 49.1) and those that did not report fatigue and had higher levels of QoL (mean = 72.1). The interviews emphasized CRF's profound impact on the patients' lives that was reflected on the following themes: “dependency on others,” “loss of power over decision making,” and “daily living disruption.” Cancer related fatigue is a significant problem for patients with advanced prostate cancer and one that affects their QoL in various ways.

    We present two new features of an ongoing effort to bring recent newsworthy advances in planetary science to undergraduate lecture halls. The effort, called 'Discoveries in Planetary Sciences', summarizes selected recently announced discoveries that are 'too new for textbooks' in the form of 3-slide PowerPoint presentations. The first slide describes the discovery, the second slide discusses the underlying planetary science concepts at a level appropriate for students of 'Astronomy 101', and the third presents the big picture implications of the discovery. A fourth slide includes links to associated press releases, images, and primary sources.

    Systemic neo-adjuvant therapy plays a primary role in the management of locally advanced breast cancer. Without having any negative effect in overall survival, induction chemotherapy potentially assures a surgery approach in unresectable disease or a conservative treatment in technically resectable disease and acts on a well-vascularized tumor bed, without the modifications induced by surgery. A specific issue has a central function in the neo-adjuvant setting: lymph nodes status. It still represents one of the strongest predictors of long-term prognosis in breast cancer. The discussion of regional radiation therapy should be a matter of debate, especially in a pathological complete response. Currently, the indication for radiotherapy is based on the clinical stage before the surgery, even for the irradiation of the loco-regional lymph nodes. Regardless of pathological down-staging, radiation therapy is accepted as standard adjuvant treatment in locally advanced breast cancer. PMID:25247013

  14. Learning contextual gene set interaction networks of cancer with condition specificity

    2013-01-01

    Background Identifying similarities and differences in the molecular constitutions of various types of cancer is one of the key challenges in cancer research. The appearances of a cancer depend on complex molecular interactions, including gene regulatory networks and gene-environment interactions. This complexity makes it challenging to decipher the molecular origin of the cancer. In recent years, many studies reported methods to uncover heterogeneous depictions of complex cancers, which are often categorized into different subtypes. The challenge is to identify diverse molecular contexts within a cancer, to relate them to different subtypes, and to learn underlying molecular interactions specific to molecular contexts so that we can recommend context-specific treatment to patients. Results In this study, we describe a novel method to discern molecular interactions specific to certain molecular contexts. Unlike conventional approaches to build modular networks of individual genes, our focus is to identify cancer-generic and subtype-specific interactions between contextual gene sets, of which each gene set share coherent transcriptional patterns across a subset of samples, termed contextual gene set. We then apply a novel formulation for quantitating the effect of the samples from each subtype on the calculated strength of interactions observed. Two cancer data sets were analyzed to support the validity of condition-specificity of identified interactions. When compared to an existing approach, the proposed method was much more sensitive in identifying condition-specific interactions even in heterogeneous data set. The results also revealed that network components specific to different types of cancer are related to different biological functions than cancer-generic network components. We found not only the results that are consistent with previous studies, but also new hypotheses on the biological mechanisms specific to certain cancer types that warrant further

    Medical oncologists are involved in cancer chemotherapy as well as end-of-life care. Recently, an increased number of patients with advanced cancer have expressed their preference to receive palliative care at their home during the end-of-life period, and several home medical care providers have aimed to provide such a service. The number of cancer patients who wish to receive home palliative care has also increased at our institution. We reviewed the characteristics of advanced cancer patients who received chemotherapy and who eventually received homecare from 2012 to 2014. The total number of patients was 22. Of these, 9 had breast cancer(40.9%)and 8 had colorectal cancer(36.4%). The median age was 68(range 36-90) years. Half of these patients died at home. The median duration of homecare to death was 64.5(range 12-252)days. Approximately 70% of patients were able to remain at home for over a month, but 3 patients died within 2 weeks at home and 1 patient returned to the hospital after 10 days of homecare due to disease progression. While palliative care in the home setting is valued by many cancer patients in the end-of-life period, close monitoring is needed for patients with rapidly progressing disease.

    Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, yet not every new, promising combination achieves a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also the genetic disposition of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Health-economic concerns are also being taken into consideration more frequently, meaning political decisions may also become a factor. This review presents the trends over the past year.

    2013-12-01

    To provide therapeutic alternatives to intravenous colon chemotherapy major recent research is focusing on the development of oral chemotherapeutic agents with the intention to improve the quality of life of patients. Initially 5-fluorouracil was most commonly used for the treatment of colorectal cancer but currently oxaliplatin and irinotecan are also available. The majority of these new drugs are pyrimidines and their analogs. The rationale for using oral anticancer agents is discussed and new drugs, such as farnesyl protein transferase inhibitor S-1, rubitecan, ZD9331, MMI-166, eflornithine, sulindac, and oral camptothecin analogs, among others, are presented with the results of their preclinical and clinical developments. This article focuses on the advancement of clinical development and also discusses the relative merits and demerits of these agents. The accelerated approval of these agents by regulatory authorities is supported by survival benefit, response rate and time to progression.

  19. Letrozole in advanced breast cancer: the PO25 trial

    PubMed Central

    2007-01-01

    Tamoxifen has been a standard first-line endocrine therapy for post-menopausal women with hormone-responsive advanced breast cancer, but more than half of patients fail to respond and time to progression is less than 12 months in responders. The third-generation aromatase inhibitors were developed to provide more effective alternatives to tamoxifen. In the Femara Study PO25, post-menopausal women with advanced breast cancer were randomized to receive letrozole 2.5 mg (n = 453) or tamoxifen 20 mg (n = 454) given orally daily until progressive disease occurred. Patients were permitted to cross over to the other treatment at progression. In the primary efficacy analysis, median time to progression (TTP) was significantly longer with letrozole than with tamoxifen (9.4 months vs. 6.0 months, respectively; P < 0.0001). The objective response rate (ORR) was significantly higher for letrozole than for tamoxifen (32% vs. 21%; P = 0.0002). Prospectively planned analyses of the intent-to-treat population showed that letrozole significantly improved overall survival (OS) compared with tamoxifen over the first 24 months of the trial. An exploratory analysis of patients, who did not cross over, indicated a median OS benefit of 14 months for letrozole compared with tamoxifen. Letrozole is the only third-generation aromatase inhibitor that has demonstrated significant improvements in ORR, TTP, and early OS. PMID:17333340

    The environment is an underutilized pathway to breast cancer prevention. Current research approaches and funding streams related to breast cancer and the environment are unequal to the task at hand. We undertook the California Breast Cancer Prevention Initiatives, a four-year comprehensive effort to set a research agenda related to breast cancer, the environment, disparities and prevention. We identified 20 topics for Concept Proposals reflecting a life-course approach and the complex etiology of breast cancer; considering the environment as chemical, physical and socially constructed exposures that are experienced concurrently: at home, in the community and at work; and addressing how we should be modifying the world around us to promote a less carcinogenic environment. Redirecting breast cancer research toward prevention-oriented discovery could significantly reduce the incidence and associated disparities of the disease among future generations.

    Lay health advisor (LHA) programs have made strong contributions towards the elimination of health disparities and are increasingly being implemented to promote health and prevent disease. Developed in collaboration with African-American survivors, the National Witness Project (NWP) is an evidence-based, community-led LHA program that improves cancer screening among African-American women. NWP has been successfully disseminated, replicated, and implemented nationally in over 40 sites in 22 states in diverse community settings, reaching over 15,000 women annually. We sought to advance understanding of barriers and facilitators to the long-term implementation and sustainability of LHA programs in community settings from the viewpoint of the LHAs, as well as the broader impact of the program on African-American communities and LHAs. In the context of a mixed-methods study, in-depth telephone interviews were conducted among 76 African-American LHAs at eight NWP sites at baseline and 12-18 months later, between 2010 and 2013. Qualitative data provides insight into inner and outer contextual factors (e.g., community partnerships, site leadership, funding), implementation processes (e.g., training), as well as characteristics of the intervention (e.g., perceived need and fit in African-American community) and LHAs (e.g., motivations, burnout) that are perceived to impact the continued implementation and sustainability of NWP. Factors at the contextual levels and related to motivations of LHAs are critical to the sustainability of LHA programs. We discuss how findings are used to inform (1) the development of the LHA Sustainability Framework and (2) strategies to support the continued implementation and sustainability of evidence-based LHA interventions in community settings.

    The manipulation of the immune system through the administration of a vaccine to direct an effective and long-lasting immune response against breast cancer (BC) cells is an attractive strategy. Vaccines would have several theoretical advantages over standard therapies, including low toxicities, high specificity, and long-lasting efficacy due to the establishment of immunological memory. However, BC vaccines have failed to demonstrate meaningful results in clinical trials so far. This reflects the intrinsic difficulty in breaking the complex immune-escaping mechanisms developed by cancer cells. New vaccines should be able to elicit complex immunologic response involving multiple immune effectors such as cytotoxic and antibody-secreting B cells, innate immunity effectors, and memory cells. Moreover, especially in patients with large tumor burdens and metastatic disease, combining vaccines with other strategies, such as systemic BC therapies, passive immunotherapy, or immunomodulatory agents, could increase the effectiveness of each approach. Here, we review recent advances in BC vaccines, focusing on suitable targets and innovative strategies. We report results of most recent trials investigating active immunotherapy in BC and provide possible future perspectives in this field of research. PMID:25339848

    The outcome of recurrent brain metastasis is dismal. This study aims to assess the clinical outcomes and toxicity of reirradiation as a salvage treatment for progressive brain metastasis in patients with advanced breast cancer. Between July 2005 and September 2014, the medical records of 56 patients with brain metastasis from breast cancer were retrospectively reviewed. Of these patients, 39 received whole-brain radiotherapy (WBRT) followed by stereotactic radiosurgery (SRS) reirradiation (Group 1), and 17 received SRS followed by WBRT reirradiation (Group 2). Overall survival (OS) and brain progression-free survival rates/times were calculated using the Kaplan–Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Change in neurologic function was also assessed. The median OS was 10.8 months (range, 1.3–56.8 months). In Group 1, the median PFS time (PFS-1) was 6.5 months and the OS time was 11.4 months. Multivariate analysis revealed that longer OS was significantly associated with a high Karnofsky performance score (KPS) (P = 0.004), controlled extracranial metastasis (P = 0.001) and a good response to reirradiation (P = 0.034). In Group 2, the median PFS time (PFS-2) after reirradiation was 8.5 months and the OS time was 10.8 months. Multivariate analysis revealed that longer OS was significantly associated with a high KPS (P = 0.018). The majority of the patients had improved or stable neurological function. Reirradiation is an effective and a safe treatment for patients with brain metastases from breast cancer. It might delay the progression of intracranial disease and improve neurological function. A suitable patient selection for reirradiation was suggested. PMID:27707842

    The identification of molecular markers associated with response to specific therapy is a key step for the implementation of personalised treatment strategies in patients with metastatic prostate cancer. Only in a low proportion of patients biopsies of metastatic tissue are performed. Circulating tumour cells (CTC), cell-free DNA (cfDNA) and RNA offer the potential for non-invasive characterisation of disease and molecular stratification of patients. Furthermore, a 'liquid biopsy' approach permits longitudinal assessments, allowing sequential monitoring of response and progression and the potential to alter therapy based on observed molecular changes. In prostate cancer, CTC enumeration using the CellSearch© platform correlates with survival. Recent studies on the presence of androgen receptor (AR) variants in CTC have shown that such molecular characterisation of CTC provides a potential for identifying patients with resistance to agents that inhibit the androgen signalling axis, such as abiraterone and enzalutamide. New developments in CTC isolation, as well as in vitro and in vivo analysis of CTC will further promote the use of CTC as a tool for retrieving molecular information from advanced tumours in order to identify mechanisms of therapy resistance. In addition to CTC, nucleic acids such as RNA and cfDNA released by tumour cells into the peripheral blood contain important information on transcriptomic and genomic alterations in the tumours. Initial studies have shown that genomic alterations of the AR and other genes detected in CTC or cfDNA of patients with castration-resistant prostate cancer correlate with treatment outcomes to enzalutamide and abiraterone. Due to recent developments in high-throughput analysis techniques, it is likely that CTC, cfDNA and RNA will be an important component of personalised treatment strategies in the future.

    The incidence of nonmelanoma skin cancer (NMSC) is rising. Research in the field of these tumors is aimed toward developing earlier and less invasive diagnostic methods and more effective, more accessible therapeutic options. Although there is much advancement in the diagnosis and treatment of NMSC, there are few literatures cataloging these developments. The aim of this review was to present the sensitivity and specificity of new imaging modalities, the dosing regimen and clearance rates of topical treatments, newer systemic treatment modalities, and discuss developments in the use of radiation as a mode of therapy. Recent developments in the diagnosis of NMSC include imaging modalities such as reflectance confocal microscopy, elastic scattering spectroscopy, and spectrophotometric intracutaneous analysis. Recent advances in the treatment of these tumors include systemic therapies such as epidermal growth factor receptor inhibitors, and topical immunomodulating drugs such as imiquimod. The progress in the diagnosis and treatment of these tumors is a gradual but fruitful growth. Scientists and clinicians alike must continue their exploration and study to address these tumors and, hopefully in the future, prevent their occurrence.

    The incidence of thyroid cancer and its associated morbidity has shown the most rapid increase among all cancers since 1982, but the mechanisms involved in thyroid cancer, particularly significant key genes induced in thyroid cancer, remain undefined. In many studies, gene probes have been used to search for key genes involved in causing and facilitating thyroid cancer. As a result, many possible virulence genes and pathways have been identified. However, these studies lack a case contrast for selecting the most possible virulence genes and pathways, as well as conclusive results with which to clarify the mechanisms of cancer development. In the present study, we used gene set enrichment and meta-analysis to select key genes and pathways. Based on gene set enrichment, we identified 5 downregulated and 4 upregulated mixed pathways in 6 tissue datasets. Based on the meta-analysis, there were 17 common pathways in the tissue datasets. One pathway, the p53 signaling pathway, which includes 13 genes, was identified by both the gene set enrichment analysis and meta-analysis. Genes are important elements that form key pathways. These pathways can induce the development of thyroid cancer later in life. The key pathways and genes identified in the present study can be used in the next stage of research, which will involve gene elimination and other methods of experimentation.

    Novel blood-based screening tests are strongly desirable for early detection of colorectal cancer (CRC). We aimed to identify and evaluate autoantibodies against tumor-associated antigens as biomarkers for early detection of CRC. 380 clinically identified CRC patients and samples of participants with selected findings from a cohort of screening colonoscopy participants in 2005–2013 (N=6826) were included in this analysis. Sixty-four serum autoantibody markers were measured by multiplex bead-based serological assays. A two-step approach with selection of biomarkers in a training set, and validation of findings in a validation set, the latter exclusively including participants from the screening setting, was applied. Anti-MAGEA4 exhibited the highest sensitivity for detecting early stage CRC and advanced adenoma. Multi-marker combinations substantially increased sensitivity at the price of a moderate loss of specificity. Anti-TP53, anti-IMPDH2, anti-MDM2 and anti-MAGEA4 were consistently included in the best-performing 4-, 5-, and 6-marker combinations. This four-marker panel yielded a sensitivity of 26% (95% CI, 13–45%) for early stage CRC at a specificity of 90% (95% CI, 83–94%) in the validation set. Notably, it also detected 20% (95% CI, 13–29%) of advanced adenomas. Taken together, the identified biomarkers could contribute to the development of a useful multi-marker blood-based test for CRC early detection. PMID:26909861

    As patients with advanced-stage cancer move from the initial diagnosis through treatment, remission, recurrence, and advanced-stage disease, the hope trajectory undergoes a dynamic transformation. By identifying the hope trajectory, nurses can help patients focus on obtainable hope objects while balancing the need to present a realistic prognosis. This, in turn, may help patients find meaning and purpose in advanced-stage cancer and facilitate realistic hope when faced with a life-threatening illness.

    Pneumocystis jiroveci pneumonia (PCP) has long been recognized as a cause of mortality in immuno-compromised populations, including those with advanced lung cancer. Although Pneumocystis colonization has only recently been described due to the development of more sensitive molecular techniques, including polymerase chain reaction (PCR), it is unknown whether Pneumocystis colonization leads to the development of PCP. In the present study, we aimed to determine the prevalence of Pneumocystis colonization in advanced lung cancer patients. Furthermore, the association between PCP and Pneumocystis colonization was also investigated. Advanced lung cancer patients with no indication of PCP were evaluated to determine the prevalence of Pneumocystis colonization. We analyzed their oral wash (OW) samples and retrospectively evaluated advanced lung cancer patients with PCP by analyzing their sections of formalin-fixed, paraffin-embedded lung tissues obtained following a diagnosis of lung cancer. Pneumocystis colonization was determined by a PCR test for Pneumocystis jiroveci (P. jiroveci). No P. jiroveci was detected by PCR in the OW samples of 47 advanced lung cancer patients with no indication of PCP, or in the lung tissues of four advanced lung cancer patients with PCP. These results indicate that PCP is not associated with Pneumocystis colonization in advanced lung cancer patients, although this study is limited since this was a cross-sectional and retrospective study.

    2016-01-01

    Introduction Child Health and Nutrition Research Initiative (CHNRI) started as an initiative of the Global Forum for Health Research in Geneva, Switzerland. Its aim was to develop a method that could assist priority setting in health research investments. The first version of the CHNRI method was published in 2007–2008. The aim of this paper was to summarize the history of the development of the CHNRI method and its key conceptual advances. Methods The guiding principle of the CHNRI method is to expose the potential of many competing health research ideas to reduce disease burden and inequities that exist in the population in a feasible and cost–effective way. Results The CHNRI method introduced three key conceptual advances that led to its increased popularity in comparison to other priority–setting methods and processes. First, it proposed a systematic approach to listing a large number of possible research ideas, using the “4D” framework (description, delivery, development and discovery research) and a well–defined “depth” of proposed research ideas (research instruments, avenues, options and questions). Second, it proposed a systematic approach for discriminating between many proposed research ideas based on a well–defined context and criteria. The five “standard” components of the context are the population of interest, the disease burden of interest, geographic limits, time scale and the preferred style of investing with respect to risk. The five “standard” criteria proposed for prioritization between research ideas are answerability, effectiveness, deliverability, maximum potential for disease burden reduction and the effect on equity. However, both the context and the criteria can be flexibly changed to meet the specific needs of each priority–setting exercise. Third, it facilitated consensus development through measuring collective optimism on each component of each research idea among a larger group of experts using a simple

    Background: Cancer survival in England is lower than the European average, which has been at least partly attributed to later stage at diagnosis in English patients. There are substantial regional and demographic variations in cancer survival across England. The majority of patients are diagnosed following symptomatic or incidental presentation. This study defines a methodology by which the route the patient follows to the point of diagnosis can be categorised to examine demographic, organisational, service and personal reasons for delayed diagnosis. Methods: Administrative Hospital Episode Statistics data are linked with Cancer Waiting Times data, data from the cancer screening programmes and cancer registration data. Using these data sets, every case of cancer registered in England, which was diagnosed in 2006–2008, is categorised into one of eight ‘Routes to Diagnosis'. Results: Different cancer types show substantial differences between the proportion of cases that present by each route, in reasonable agreement with previous clinical studies. Patients presenting via Emergency routes have substantially lower 1-year relative survival. Conclusion: Linked cancer registration and administrative data can be used to robustly categorise the route to a cancer diagnosis for all patients. These categories can be used to enhance understanding of and explore possible reasons for delayed diagnosis. PMID:22996611

    Describe a modified approach to the technique for staging laparoscopic extraperitoneal aortic and common iliac lymph node dissection for locally advanced cervical cancer.Retrospective, nonrandomized clinical study. (Canadian Task Force classification II-2), setting in an acute-care, teaching hospital. Thirty-six patients with locally advanced cervical cancer underwent laparoscopic surgical staging via extraperitoneal approach with the conventional or the modified technique from August 2001 through September 2004. Clinical outcomes in 23 patients who were operated on with the conventional technique using index finger for first trocar entrance; 12 patients with the modified technique using direct trocar entrance, were compared. One patient was excluded due to peritoneal carcinomatosis. Technique, baseline characteristics, histopathologic variables and surgical outcome were measured. There were no significant differences in patients basal characteristics on comparative analysis between conventional and modified technique. With our proposed modified technique, we obtained a reduced surgical procedure duration and blood loss. The proposed modified surgical technique offers some advantages, is an easier approach because the parietal pelvic peritoneum is elastic and this helps to avoid its disruption at time of trocar insertion, size of incision is shorter, we achieved no CO2 leak through the trocar orifice, and wound suture is fast and simple.

    We studied the clinical efficacy of pre-operative combination chemotherapy using S-1 plus oxaliplatin for advanced gastric cancer. Four patients hadclinical Stage IV disease, 1 patient had clinical Stage III C disease, 2 patients had clinical Stage III B disease, and 1 patient had clinical Stage III A disease. The patients received 2-8 courses of oxaliplatin(130mg/m2)on day 1, andS -1 on days 1-14 every 3 weeks. The response rate was 56%(5 PR, 1 PD, and2 SD), andthe disease control rate was 88%. Toxicities were Grade 2 anemia, Grade 1 peripheral neuropathy, Grade 1 fatigue, and anorexia. Five of the 8 patients underwent R0 surgery after SOX chemotherapy, and no severe complications occurred. Histological responses were Grade 3 for 2 cases, Grade 2 for 2 cases, andGrad e 1a for 1 case. The SOX regimen showeda high objective tumor response, andis one of the promising regimens in the neoadjuvant setting for well-advanced gastric cancer.

    This systematic review summarised the literature on patient acceptability of screening for oral cancer outside dental care settings. A comprehensive search of relevant literature was performed in EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, CINAHAL, psycINFO, CANCERLIT and BNI to identify relevant articles published between 1975 and Dec 2013. Studies reporting acceptability of oral cancer screening to undiagnosed individuals attending non-dental settings were eligible for inclusion. A total of 2935 references were initially identified from the computerised search but 2217 were excluded after screening the titles. From the abstracts of the remaining 178 articles, 47 full text articles were retrieved for further scrutiny, and 12 studies were found to be eligible for inclusion. In these studies, knowledge about oral cancer, anxiety related to the screening process, preference for care provision, and financial cost were influencing factors for the acceptance of screening. Written information provided to patients in primary care was reported to boost immediate knowledge levels of oral cancer, lessen anxiety, and increase intentions for screening. The majority of screening methods were entirely acceptable to patients; lack of acceptability from the patients' viewpoint was not a significant barrier to carrying out opportunistic screening of high-risk populations. In conclusion, the available evidence suggests that acceptance of, and satisfaction with oral cancer screening is high, particularly where patients have previously been educated about oral cancer. Further research focusing on patient's preferences would enable streamlining of the approach to oral cancer screening taken by any national programme.

    Pancreatic cancer is one of the most lethal cancers among all malignances, with a median overall survival of <1 year and a 5-year survival of ~5%. The dismal survival rate and prognosis are likely due to lack of early diagnosis, fulminant disease course, high metastasis rate, and disappointing treatment outcome. Pancreatic cancers harbor a variety of genetic alternations that render it difficult to treat even with targeted therapy. Recent studies revealed that pancreatic cancers are highly enriched with a cancer stem cell (CSC) population, which is resistant to chemotherapeutic drugs, and therefore escapes chemotherapy and promotes tumor recurrence. Cancer cell epithelial to mesenchymal transition (EMT) is highly associated with metastasis, generation of CSCs, and treatment resistance in pancreatic cancer. Reviewed here are the molecular biology of pancreatic cancer, the major signaling pathways regulating pancreatic cancer EMT and CSCs, and the advancement in current clinical and experimental treatments for pancreatic cancer.

    Background Endocrine therapy constitutes a central modality in the treatment of oestrogen receptor (ER)-positive advanced breast cancer. Purpose To evaluate the evidence for endocrine treatment in postmenopausal patients with advanced breast cancer focusing on the aromatase inhibitors, letrozole, anastrozole, exemestane and fulvestrant. Methods A review was carried out using PubMed. Randomised phase II and III trials reporting on ≥100 patients were included. Results 35 trials met the inclusion criteria. If not used in the adjuvant setting, a non-steroid aromatase inhibitor was the optimal first-line option. In general, the efficacy of the different aromatase inhibitors and fulvestrant was similar in tamoxifen-refractory patients. A randomised phase II trial of palbociclib plus letrozole versus letrozole alone showed significantly increased progression-free survival (PFS) when compared with endocrine therapy alone in the first-line setting (20.2 vs 10.2 months). Furthermore, the addition of everolimus to exemestane in the Breast Cancer Trials of OraL EveROlimus-2 (BOLERO-2) study resulted in an extension of median PFS by 4.5 months after recurrence/progression on a non-steroid aromatase inhibitor. However, overall survival was not significantly increased. Conclusion Conventional treatment with an aromatase inhibitor or fulvestrant may be an adequate treatment option for most patients with hormone receptor-positive advanced breast cancer. Mammalian target of rapamycin (mTOR) inhibition and cyclin-dependent kinase 4/6 (CDK4/6) inhibition might represent substantial advances for selected patients in some specific settings. However, there is an urgent need for prospective biomarker-driven trials to identify patients for whom these treatments are cost-effective. PMID:27843622

    Prostate cancer is the most frequent and second most lethal cancer in men in the United States. Innate immunity and inflammation may increase the risk of prostate cancer. To determine the role of innate immunity and inflammation in advanced prostate cancer, we investigated the association of 320 single nucleotide polymorphisms, located in 46 genes involved in this pathway, with disease risk using 494 cases with advanced disease and 536 controls from Cleveland, Ohio. Taken together, the whole pathway was associated with advanced prostate cancer risk (P = 0.02). Two sub-pathways (intracellular antiviral molecules and extracellular pattern recognition) and four genes in these sub-pathways (TLR1, TLR6, OAS1, and OAS2) were nominally associated with advanced prostate cancer risk and harbor several SNPs nominally associated with advanced prostate cancer risk. Our results suggest that the innate immunity and inflammation pathway may play a modest role in the etiology of advanced prostate cancer through multiple small effects.

    Bladder cancer is a common disease representing the fifth most diagnosed solid tumor in the United States. Despite this, advances in our understanding of the molecular etiology and treatment of bladder cancer have been relatively lacking. This is especially apparent when recent advances in other cancers, such as breast and prostate, are taken into consideration. The field of bladder cancer research is ready and poised for a series of paradigm-shifting discoveries that will greatly impact the way this disease is clinically managed. Future preclinical discoveries with translational potential will require investigators to take full advantage of recent advances in molecular and animal modeling methodologies. We present an overview of current preclinical models and their potential roles in advancing our understanding of this deadly disease and for advancing care.

    Recently, targeted drugs have been developed for the treatment of colorectal cancer(CRC). Among targets, it is well known that KRAS mutations are associated with resistance to epidermal growth factor receptor(EGFR)monoclonal antibodies. However, response rates using anti-EGFR monotherapy for CRC were less than 20-30% in previous clinical studies. Thus, because the RAS/MAP2K/MAPK and PI3K/AKT pathways are associated with CRC resistance to chemotherapy, we analyzed gene mutations in Stage IV CRC patients using a genomic test(CancerPlex®). Medical records were reviewed for 112 patients who received treatment for CRC between 2007 and 2015 in Niigata University Medical and Dental Hospital or Niigata Cancer Center Hospital. There were 66 male and 46 female patients, and their median age was 62.5(range, 30-86) years. Cluster analyses were performed in 110 non-hypermutated Japanese CRC patients using Euclidean distance and Ward's clustering method, and 6 typical groups were identified. Among these, patients with all wild-type actionable genes benefited from anti-EGFR therapies. The expense of targeted drugs warrants consideration of cost-effectiveness during treatment decision-making for advanced CRC patients. To this end, based on the genetic information on CRC, it is possible to develop precision medicine using CancerPlex®.

  9. Controversies in the management of advanced prostate cancer

    For advanced prostate cancer, the main hormone treatment against which other treatments are assessed is surgical castration. It is simple, safe and effective, however it is not acceptable to all patients. Medical castration by means of luteinizing hormone-releasing hormone (LH-RH) analogues such as goserelin acetate provides an alternative to surgical castration. Diethylstilboestrol, previously the only non-surgical alternative to orchidectomy, is no longer routinely used. Castration reduces serum testosterone by around 90%, but does not affect androgen biosynthesis in the adrenal glands. Addition of an anti-androgen to medical or surgical castration blocks the effect of remaining testosterone on prostate cells and is termed combined androgen blockade (CAB). CAB has now been compared with castration alone (medical and surgical) in numerous clinical trials. Some trials show advantage of CAB over castration, whereas others report no significant difference. The author favours the view that CAB has an advantage over castration. No study has reported that CAB is less effective than castration. Of the anti-androgens which are available for use in CAB, bicalutamide may be associated with a lower incidence of side-effects compared with the other non-steroidal anti-androgens and, in common with nilutamide, has the advantage of once-daily dosing. Only one study has compared anti-androgens within CAB: bicalutamide plus LH-RH analogue and flutamide plus LH-RH analogue. At 160-week follow-up, the groups were equivalent in terms of survival and time to progression. However, bicalutamide caused significantly less diarrhoea than flutamide. Withdrawal and intermittent therapy with anti-androgens extend the range of treatment options. © 1999 Cancer Research Campaign PMID:10408706

    A man in his 60s was admitted for the treatment of advanced cervical esophageal cancer with metastasis to the lymph nodes and advanced tongue cancer with metastasis to the lymph nodes. Esophageal cancer was suspected to have invaded the trachea. The tongue cancer was located on the left side and had invaded beyond the median line of the tongue. Both cancers were pathologically diagnosed as squamous cell carcinomas. Therefore, it was determined that pharyngo-laryngo- esophagectomy and total glossectomy were required prior to the treatment. However, after 2 courses of docetaxel/cisplatin/ 5-FU combined induction chemotherapy, both cancers remarkably decreased; consequently, an esophagectomy to preserve laryngeal function and partial glossectomy could be performed simultaneously. The patient is well without recurrence 1 year post-surgery.

    Clinical and epidemiological data suggest coronary artery disease shares etiology with prostate cancer (PCa). The aim of this work was to assess the effects of several serum markers reported in cardiovascular disease on PCa. Serum markers (oxidized low-density lipoprotein [ox-LDL], apolipoprotein [apo] B100, and apoB48) in peripheral blood samples from 50 patients from Fudan University Shanghai Cancer Center (FUSCC) with localized or lymph node metastatic PCa were investigated in this study. Twenty-five samples from normal individuals were set as controls. We first conducted enzyme-linked immunosorbent assay analysis to select candidate markers that were significantly different between these patients and controls. Then, the clinical relevance between OLR1 (the ox-LDL receptor) expression and PCa was analyzed in The Cancer Genome Atlas (TCGA) cohort. We also investigated the function of ox-LDL in PCa cell lines in vitro. Phosphorylation protein chips were used to analyze cell signaling pathways in ox-LDL-treated PC-3 cells. The ox-LDL level was found to be significantly correlated with N stage of prostate cancer. OLR1 expression was correlated with lymph node metastasis in the TCGA cohort. In vitro, ox-LDL stimulated the proliferation, migration, and invasion of LNCaP and PC-3 in a dose-dependent manner. The results of phosphoprotein microarray illustrated that ox-LDL could influence multiple signaling pathways of PC-3. Activation of proliferation promoting signaling pathways (including β-catenin, cMyc, NF-κB, STAT1, STAT3) as well as apoptosis-associating signaling pathways (including p27, caspase-3) demonstrated that ox-LDL had complicated effects on prostate cancer. Increased serum ox-LDL level and OLR1 expression may indicate advanced-stage PCa and lymph node metastasis. Moreover, ox-LDL could stimulate PCa proliferation, migration, and invasion in vitro.

    Disease progression despite existing endocrine therapies remains a major challenge to the effective management of hormone-receptor-positive (HR(+)), human epidermal growth factor receptor-2-negative (HER2(-)), advanced breast cancer. Recent advances in elucidating the molecular mechanisms of disease progression have identified the existence of adaptive "cross-talk" between the estrogen receptor (ER) and various growth factor receptor and intracellular signaling pathways, allowing breast cancer cells to escape the inhibitory effects of endocrine therapy. These findings provide the clinical rationale for enhancing or extending endocrine sensitivity by combining endocrine therapy with a targeted agent against a compensatory pathway. In BOLERO-2, adding the mTOR inhibitor everolimus to endocrine therapy significantly improved progression-free survival (PFS) in patients with HR(+) advanced breast cancer previously treated with nonsteroidal aromatase inhibitor therapy. Notably, PFS benefits were comparable in subgroup analyses of first- and later-line settings. These results contrast with those of the large first-line HORIZON study, wherein adding the mTOR inhibitor temsirolimus to endocrine therapy did not improve PFS. Therefore, it is unclear whether a targeted agent should only be combined with endocrine therapy to restore endocrine sensitivity or whether it may also prevent or delay resistance in hormone-sensitive advanced breast cancer. Numerous additional targeted agents are currently being evaluated in combination with endocrine therapies, including PI3K, cyclin-dependent kinase 4/6, SRC, and histone deacetylase inhibitors. Appropriate patient selection based on prior treatment history will become increasingly important in maximizing the incremental benefit derived from these new agents combined with existing endocrine therapies in HR(+) advanced breast cancer.

    A MESSAGE FROM ASCO'S PRESIDENT I am pleased to present Clinical Cancer Advances 2017, which highlights the most promising advances in patient-oriented cancer research over the past year. The report gives us an opportunity to reflect on what an exciting time it is for cancer research and how swiftly our understanding of cancer has improved. One year ago, the White House announced the national Cancer Moonshot program to accelerate progress against cancer. This shared vision of progress has reinvigorated the research community, identified new areas of scientific collaboration, and raised our ambitions regarding what may be possible beyond the progress we have already made. When I entered the field 35 years ago, I could not have imagined where we would be today. We can now detect cancer earlier, target treatments more effectively, and manage adverse effects more effectively to enable patients to live better, more fulfilling lives. Today, two of three people with cancer live at least 5 years after diagnosis, up from roughly one of two in the 1970s. This progress has resulted from decades of incremental advances that have collectively expanded our understanding of the molecular underpinnings of cancer. There is no better current example of this than ASCO's 2017 Advance of the Year: Immunotherapy 2.0. Over the last year, there has been a wave of new successes with immunotherapy. Research has proven this approach can be effective against a wide range of hard-to-treat advanced cancers previously considered intractable. Researchers are now working to identify biologic markers that can help increase the effectiveness of treatment and determine who is most likely to benefit from immunotherapy. This knowledge will enable oncologists to make evidence-based decisions so as many patients as possible might benefit from this new type of treatment. Each successive advance builds on the previous hard work of generations of basic, translational, and clinical cancer researchers

    A MESSAGE FROM ASCO'S PRESIDENT: For the third year, the American Society of Clinical Oncology (ASCO) is publishing Clinical Cancer Advances: Major Research Advances in Cancer Treatment, Prevention, and Screening, an annual review of the most significant cancer research presented or published over the past year. ASCO publishes this report to demonstrate the important progress being made on the front lines of clinical cancer research today. The report is intended to give all those with an interest in cancer care-the general public, cancer patients and organizations, policymakers, oncologists, and other medical professionals-an accessible summary of the year's most important cancer research advances. These pages report on the use of magnetic resonance imaging for breast cancer screening, the association between hormone replacement therapy and breast cancer incidence, the link between human papillomavirus and head and neck cancers, and the use of radiation therapy to prevent lung cancer from spreading. They also report on effective new targeted therapies for cancers that have been historically difficult to treat, such as liver cancer and kidney cancer, among many others. A total of 24 advances are featured in this year's report. These advances and many more over the past several years show that the nation's long-term investment in cancer research is paying off. But there are disturbing signs that progress could slow. We are now in the midst of the longest sustained period of flat government funding for cancer research in history. The budgets for the National Institutes of Health and the National Cancer Institute (NCI) have been unchanged for four years. When adjusted for inflation, cancer research funding has actually declined 12% since 2004. These budget constraints limit the NCI's ability to fund promising cancer research. In the past several years the number of grants that the NCI has been able to fund has significantly decreased; this year, in response to just the

    Purpose: To construct a predictive model for survival of patients referred to the Rapid Response Radiotherapy Program using recursive partitioning (RP). Methods and Materials: We analyzed 16 factors characterizing patients with metastases at first referral to the Rapid Response Radiotherapy Program for palliative radiotherapy in 1999 for their effect on survival. They included age, primary cancer site, site of metastases, weight loss ({>=}10% during the past 6 months), Karnofsky performance status (KPS), interval from the first diagnosis of cancer to the first consultation at the Rapid Response Radiotherapy Program, analgesic consumption within the previous 24 h, and the nine symptom scores from the Edmonton Symptom Assessment Scale. We used RP to develop a predictive model of survival for patients referred in 1999, followed by temporal validation using patients referred in 2000, and external validation using patients referred in 2002 to another institution. Results: The model was able to separate patients into three groups with different durations of survival that were defined by (1) KPS >60; (2) KPS {<=}60 with bone metastases only; and (3) KPS {<=}60 with other metastases. The model performed moderately well when applied to the validation sets, but a major limitation was that it led to an unequal distribution of patients, with a small proportion of patients in the intermediate group. Conclusion: We have demonstrated that RP can be used to predict the survival of patients with advanced cancer. However, this model has no advantages compared with our published prognostic models that use the survival prediction scores and number of risk factors.

    The role of perioperative chemotherapy for gastric cancer has been established for gastric cancers in their advanced stage. In most parts of the world, even in Japan and Korea, local recurrence of gastric cancer following curative resection remains a problem. Should radiation be added to chemotherapy to achieve better local and regional control? What is the current evidence? What are the concerns regarding neoadjuvant chemoradiation in terms of safety, efficacy and survival benefit? After a serious review of the literature, the authors conclude that it is still too early to get a definitive answer but radiation seems promising. It may bring a higher pathological response rate. Rationally, more high level clinical trials are needed to confirm the role of radiotherapy in the neoadjuvant setting or to ascertain subsets of patients who may benefit from it. It is of note that surgeons should pay attention to possible complicated circumstances following radiotherapy, maintain proper nutrition status and minimize the occurrence of postoperative complications. As few data are available in Japan and Korea, interpretation and implementation of neoadjuvant radiation or chemoradiation should be done with caution. PMID:22408715

    Obesity and type 2 diabetes are recognised risk factors for the development of some cancers and, increasingly, predict more aggressive disease, treatment failure, and cancer-specific mortality. Many factors may contribute to this clinical observation. Hyperinsulinaemia, dyslipidaemia, hypoxia, ER stress, and inflammation associated with expanded adipose tissue are thought to be among the main culprits driving malignant growth and cancer advancement. This observation has led to the proposal of the potential utility of “old players” for the treatment of type 2 diabetes and metabolic syndrome as new cancer adjuvant therapeutics. Androgen-regulated pathways drive proliferation, differentiation, and survival of benign and malignant prostate tissue. Androgen deprivation therapy (ADT) exploits this dependence to systemically treat advanced prostate cancer resulting in anticancer response and improvement of cancer symptoms. However, the initial therapeutic response from ADT eventually progresses to castrate resistant prostate cancer (CRPC) which is currently incurable. ADT rapidly induces hyperinsulinaemia which is associated with more rapid treatment failure. We discuss current observations of cancer in the context of obesity, diabetes, and insulin-lowering medication. We provide an update on current treatments for advanced prostate cancer and discuss whether metabolic dysfunction, developed during ADT, provides a unique therapeutic window for rapid translation of insulin-sensitising medication as combination therapy with antiandrogen targeting agents for the management of advanced prostate cancer.

    Every year, nearly five million adults with cancer are hospitalized. Limited evidence suggests that hospitalization of the cancer patient is associated with adverse morbidity and mortality. Hospitalization of the patient with advanced cancer allows for an intense examination of health status in the face of terminal illness and an opportunity for defining goals of care. This experience-based guide reports what is currently known about the topic and outlines a systematic approach to maximizing opportunities, improving quality, and enhancing the well-being of the hospitalized patient with advanced cancer.

    Pancreatic cancer is a type of common malignant tumors with high occurrence in the world. Most patients presented in clinic had pancreatic cancer at advanced stages. Furthermore, chemotherapy or radiotherapy had very limited success in treating pancreatic cancer. Complementary and alternative medicines, such as natural products/herbal medicines, represent exciting adjunctive therapies. In this review, we summarize the recent advances of using natural products/herbal medicines, such as Chinese herbal medicine, in combination with conventional chemotherapeutic agents to treat pancreatic cancer in preclinical and clinical trials.

    The aim of the study was to compare the short and long-term outcomes of older and younger colorectal cancer patients with advanced disease resected with a curative intent. Six hundred and ninety-two patients were analysed. Four hundred and seventy-nine patients were younger than 70 years (Group 1), and 213 were 70 years of age or above (Group 2). The overall perioperative mortality rate in the younger group was 0.8% (n = 7), as against 1.4% (n = 3) in the elderly group (p = NS). The morbidity rates were 35% and 42%, respectively (p = NS). At univariate analysis, the elderly patients had a worse overall survival compared to the younger group, when only patients undergoing postoperative chemo-radiotherapy were considered (54% vs 67% overall survival at 5 years; p = 0.03). Using logistic regression analysis, tumour stage (p < 0.0001) and radicality of surgery (p < 0.0001) correlated significantly with overall survival rates in the elderly. Colorectal surgery for malignancy can be performed safely in the elderly with acceptable morbidity and mortality rates and long-term survival.

    Purpose: To evaluate local control for patients with locally advanced noninflammatory breast cancer (LABC) managed by selective mastectomy. Methods and Materials: Between 1979 and 1996, 176 patients with LABC were prospectively managed by chemotherapy (CT)-irradiation (RT)-CT without routine mastectomy. All surviving patients were followed for a minimum of 5 years. Results: A total of 132 patients (75%) had a T4 tumor and 22 (12.5%) supraclavicular nodal disease. The clinical complete response rate was 91% (160/176), which included 13 patients who underwent mastectomy and 2 an iridium wire implant. The first site of failure was local for 43 patients (breast {+-} axilla for 38); 27 of these patients underwent salvage mastectomy and 11 did not for an overall mastectomy rate of 23% (40/176). If all 176 patients had undergone routine mastectomy (136 extra mastectomies), 11 additional patients may have avoided an unsalvageable first local relapse. The others would have either have not had a local relapse or would have suffered local relapse after distant disease. No tumor or treatment related factor was found to predict local disease at death. Median disease-free and overall survival for all patients was 26 and 52 months, respectively. Conclusions: Selective mastectomy in LABC may not jeopardize local control or survival.

  4. Hypofractionated ablative radiotherapy for locally advanced pancreatic cancer

    2016-01-01

    The role of radiation in locally advanced unresectable pancreatic cancer (LAPC) is controversial. Randomized trials evaluating standard doses of chemoradiation have not shown a significant benefit from the use of consolidative radiation. Results from non-randomized studies of 3–5-fraction stereotactic body radiotherapy (SBRT) have been similar to standard chemoradiation, but with less toxicity and a shorter treatment time. Doses of SBRT have been reduced to subablative levels for the sake of tolerability. The benefit of both options is unclear. In contrast, ablative doses can be delivered using an SBRT technique in 15–28 fractions. The keys to the delivery of ablative doses are computed tomography (CT) image guidance and respiratory gating. Higher doses have resulted in encouraging long-term survival results. In this review, we present a comprehensive solution to achieving ablative doses for selected patients with pancreatic tumors by using a combination of classical, modern and novel concepts of radiotherapy: fractionation, CT image guidance, respiratory gating, intentional dose heterogeneity, and simultaneous integrated protection.

    Gemcitabine is a pyrimidine nucleoside antimetabolite agent which is active in several human malignancies, including nonsmall cell lung cancer (NSCLC). Because of its acceptable toxicity profile, with myelosuppression being the most common adverse event, gemcitabine can be safely combined with a number of cytotoxic agents, including platinum derivatives and new-generation anticancer compounds. In fact, the combination of gemcitabine and cisplatin is a first-line treatment for patients with advanced NSCLC, pharmacoeconomic data indicating that it represents the most cost-effective regimen among platinum-based combinations with third-generation cytotoxic drugs. The drug has been investigated in the context of nonplatinum-based regimens in a number of prospective clinical trials, and might provide a suitable alternative for patients with contraindications to platinum. Recently, gemcitabine-based doublets have been successfully tested in association with novel targeted agents with encouraging results, providing further evidence for the role of the drug in the treatment of NSCLC. In the last few years several attempts have been pursued in order to identify molecular predictors of gemcitabine activity, and recent data support the feasibility of genomic-based approaches to customize treatment with the ultimate goal of improving patient outcome.

    Therapeutic options in advanced renal-cell cancer have expanded through better understanding of molecular pathology and development of novel targeted therapeutics. Vascular endothelial growth factor, the key ligand of angiogenesis, has a major role in the progression of vascularized kidney tumors and this is the target molecule of modern medications. The three types of the mechanism of action of current therapies are: monoclonal antibodies blocking directly vascular endothelial growth factor ligand (bevacizumab), tyrosine-kinase inhibitors blocking vascular endothelial growth factor receptors (sorafenib, sunitinib, pazopanib) and inhibitors of the intracellular mTOR-kinase (temsirolimus, everolimus). Based on randomized studies, sunitinib, pazopanib or interferon-α-bevacizumab combination should be the first-line therapy in patients with good/moderate prognosis, while temsirolimus is recommended in those with poor prognosis. Following an ineffective cytokine therapy sorafenib or pazopanib are the second-line treatment. In case of tyrosine-kinase inhibitor inefficacy, current evidence favors everolimus. Patient outcome can further be improved by the involvement of more modern and effective target products.

    In this systematic review, we sought to evaluate the effect of physical activity or nutrition interventions (or both) in adults with advanced non-small-cell lung cancer (nsclc). Methods A systematic search for relevant clinical trials was conducted in 6 electronic databases, by hand searching, and by contacting key investigators. No limits were placed on study language. Information about recruitment rates, protocol adherence, patient-reported and clinical outcome measures, and study conclusions was extracted. Methodologic quality and risk of bias in each study was assessed using validated tools. Main Results Six papers detailing five studies involving 203 participants met the inclusion criteria. Two of the studies were single-cohort physical activity studies (54 participants), and three were controlled nutrition studies (149 participants). All were conducted in an outpatient setting. None of the included studies combined physical activity with nutrition interventions. Conclusions Our systematic review suggests that exercise and nutrition interventions are not harmful and may have beneficial effects on unintentional weight loss, physical strength, and functional performance in patients with advanced nsclc. However, the observed improvements must be interpreted with caution, because findings were not consistent across the included studies. Moreover, the included studies were small and at significant risk of bias. More research is required to ascertain the optimal physical activity and nutrition interventions in advanced inoperable nsclc. Specifically, the potential benefits of combining physical activity with nutrition counselling have yet to be adequately explored in this population. PMID:23904771

    This year, for the first time, the American Society of Clinical Oncology (ASCO) is publishing Clinical Cancer Advances 2005: Major Research Advances in Cancer Treatment, Prevention, and Screening, an annual review of the most significant clinical research presented or published over the past year across all cancer types. ASCO embarked on this project to provide the public, patients, policymakers, and physicians with an accessible summary of the year's most important research advances. While not intended to serve as a comprehensive review, this report provides a year-end snapshot of research that will have the greatest impact on patient care. As you will read, there is much good news from the front lines of cancer research. These pages report on new chemotherapy regimens that sharply reduce the risk of recurrence for very common cancers; the "coming of age" of targeted cancer therapies; promising studies of drugs to prevent cancer; and improvements in quality of life for people living with the disease, among many other advances. Survival rates for cancer are on the rise, increasing from 50% to 64% over the last 30 years. Cancer still exacts an enormous toll, however. Nearly 1.4 million Americans will be diagnosed this year, and some 570,000 will die of the disease. Clearly, more research is needed to find effective therapies for the most stubborn cancer types and stages. We need to know more about the long-term effects of newer, more targeted cancer therapies, some of which need to be taken over long periods of time. And we need to devote far greater attention to tracking and improving the care of the nearly 10 million cancer survivors in the United States today. Despite these and other challenges, the message of this report is one of hope. Through the dedicated, persistent pursuit of clinical research and participation in clinical trials by people with cancer, we steadily uncover new and better ways of treating, diagnosing, and preventing a disease that touches the

    Acupuncture is used to treat a variety of symptoms and conditions associated with cancer and cancer treatments. The present study was performed to evaluate the feasibility of providing acupuncture in the hospital setting for breast cancer patients and to evaluate the short-term effect of acupuncture on stress, anxiety, and pain. This was an open label study conducted at Mayo Clinic Hospital, Methodist and Saint Marys Campus, Rochester, Minnesota. A total of 20 adult breast cancer patients undergoing mastectomy and/or breast reconstruction were recruited and offered daily acupuncture intervention beginning postoperative day 1 and continuing for the duration of the hospital stay. Outcome measures included the Symptom Visual Analog Scale (VAS) and Satisfaction Question and Was-it-Worth-it (WIWI) Questionnaire. It was found that acupuncture is a feasible option for postoperative breast cancer patients. In addition, it can significantly decrease the levels of anxiety (p = 0.0065), tension/muscular discomfort (p < 0.001) and pain (p = 0.023). The association between acupuncture and relaxation was found to be statistically borderline (p = 0.053). This feasibility study showed that acupuncture can be integrated into a busy postsurgical clinical practice. These results also suggest that acupuncture may be an important intervention in the postoperative setting for breast cancer patients.

    In lung cancer, outcome measurement has been mostly limited to survival. Proper assessment of the value of lung cancer treatments, and the performance of institutions delivering care, requires more comprehensive measurement of standardised outcomes.The International Consortium for Health Outcomes Measurement convened an international, multidisciplinary working group of patient representatives, medical oncologists, surgeons, radiation oncologists, pulmonologists, palliative care specialists, registry experts and specialist nurses to review existing data and practices. Using a modified Delphi method, the group developed a consensus recommendation ("the set") on the outcomes most essential to track for patients with lung cancer, along with baseline demographic, clinical and tumour characteristics (case-mix variables) for risk adjustment.The set applies to patients diagnosed with nonsmall cell lung cancer and small cell lung cancer. Our working group recommends the collection of the following outcomes: survival, complications during or within 6 months of treatment and patient-reported domains of health-related quality of life including pain, fatigue, cough and dyspnoea. Case-mix variables were defined to improve interpretation of comparisons.We defined an international consensus recommendation of the most important outcomes for lung cancer patients, along with relevant case-mix variables, and are working to support adoption and reporting of these measures globally.

    Accurate segmentation of ovarian cancer metastases is clinically useful to evaluate tumor growth and determine follow-up treatment. We present a region-based level set algorithm with localization constraints to segment ovarian cancer metastases. Our approach is established on a representative region-based level set, Chan-Vese model, in which an active contour is driven by region competition. To reduce over-segmentation, we constrain the level set propagation within a narrow image band by embedding a dynamic localization function. The metastasis intensity prior is also estimated from image regions within the level set initialization. The localization function and intensity prior force the level set to stop at the desired metastasis boundaries. Our approach was validated on 19 ovarian cancer metastases with radiologist-labeled ground-truth on contrast-enhanced CT scans from 15 patients. The comparison between our algorithm and geodesic active contour indicated that the volume overlap was 75+/-10% vs. 56+/-6%, the Dice coefficient was 83+/-8% vs. 63+/-8%, and the average surface distance was 2.2+/-0.6mm vs. 4.4+/-0.9mm. Experimental results demonstrated that our algorithm outperformed traditional level set algorithms.

    Histone-methyl transferases (HMTs) are key enzymes that post-translationally modify histones, and serve key role in gene expression, epigenetic regulation, and as determinants of survival in malignant cells. Recent studies have shed light on the role of hSET1 which is a key element of highly conserved multi-protein HMT complex that catalyze methylation of histone H3 lysine 4 (H3K4) regulating expression of specific proteins important for the malignant phenotype. To understand the importance of differential expression of H3K4 HMTs in cancer, we specifically down-regulated hSET1 the only H3K4 specific histone methyl transferase present in yeast as well as in human that is directly involved in gene expression. hSET1 has been shown to be differentially over-expressed in the malignant cells as compared to the normal cells at the RNA as well as protein level. In a wide array of normal and malignant cells it has been demonstrated that phosphorothioate antisense against hSET1 (DN5) caused selective and differential apoptosis in malignant cells only while the normal cells remains unaffected. Downregulation of hSET1 leads to rapid and complete regression of SW480 colon xenograft in mice model. These findings demonstrate that hSET1 over-expression promotes cell proliferation and cancer cell survival, and may be a novel target for cancer therapy. PMID:19426701

    Palliative care can last from a few days to months and, in some cases, years. Consequently the nutritional needs of palliative care patients also vary, as does the extent to which nutrition intervention is pursued. Anorexia and cachexia are common side-effects of advanced cancer. They are characterized by physical depletion of the patients and an emotional drain on them, their families and carers. Pulling together the practical aspects of nutrition support and the emotional and social significance of food requires a skillful practitioner; an experienced dietitian can be a valued member of the palliative care team. This article examines the role of nutrition support in the palliative care setting, focusing upon practical advice including food modification, the use of oral supplements and enteral feeding.

    Large collections of data in studies on cancer such as leukaemia provoke the necessity of applying tailored analysis algorithms to ensure supreme information extraction. In this work, a custom-fit pipeline is demonstrated for thorough investigation of the voluminous MILE gene expression data set. Three analyses are accomplished, each for gaining a deeper understanding of the processes underlying leukaemia types and subtypes. First, the main disease groups are tested for differential expression against the healthy control as in a standard case-control study. Here, the basic knowledge on molecular mechanisms is confirmed quantitatively and by literature references. Second, pairwise comparison testing is performed for juxtaposing the main leukaemia types among each other. In this case by means of the Dice coefficient similarity measure the general relations are pointed out. Moreover, lists of candidate main leukaemia group biomarkers are proposed. Finally, with this approach being successful, the third analysis provides insight into all of the studied subtypes, followed by the emergence of four leukaemia subtype biomarkers. In addition, the class enhanced DEG signature obtained on the basis of novel pipeline processing leads to significantly better classification power of multi-class data classifiers. The developed methodology consisting of batch effect adjustment, adaptive noise and feature filtration coupled with adequate statistical testing and biomarker definition proves to be an effective approach towards knowledge discovery in high-throughput molecular biology experiments.

    Finding ways to bring effective computer-based behavioral interventions to those with limited access to technology is a continuing challenge for health educators. Computer kiosks placed in community settings may help reach such populations. The Reflections of You kiosk generates individually tailored magazines on breast cancer and mammography and was adapted from an evidence-based intervention that increased mammography use in African American women. This usage study tracked patterns of use and characteristics of kiosk users in beauty salons, churches, neighborhood health centers, Laundromats, and social service agencies in St. Louis. Kiosks were used 4,527 times in 470 kiosk days at 40 different host sites. Highly significant differences among community settings were found in rates and patterns of kiosk use as well as user characteristics, breast cancer knowledge, and use of mammography. Findings inform strategic decision making about technology dissemination and community outreach to women needing information about breast cancer and mammography.

  16. The psychosocial impact of cancer: exploring relationships between conditional goal setting and depression.

    PubMed

    Street, Helen

    2003-09-01

    This study explores depression in cancer patients with reference to conditional goal setting (CGS) theory. CGS theory proposes that depressed individuals believe that personal happiness is conditional upon attainment of specific goals (personal CGS). Other individuals may set important goals believing that goal achievement is a necessary prerequisite of social acceptance and approval (social CGS). CGS has been found to contribute to depression in normal populations. 15.2% of the 67 newly diagnosed cancer patients in this study showed clinical levels of depression. A significant relationship was identified between personal CGS, rumination and depression, as predicted in CGS theory. Two months later, 46.7% of patients demonstrated clinical levels of depression. This later experience of depression was significantly related to social CGS. The results suggest CGS involving a misdirected pursuit of happiness is initially associated with depression whereas subsequent experiences of depression are related to a misdirected pursuit of social acceptance. Implications are discussed in terms of understanding the cancer patients' motivations controlling goal setting. It is suggested that successful psychotherapy for depression in cancer patients needs to examine the motivations controlling goal setting in addition to the process of goal pursuit.

    Personalized medicine is a set of diagnostic, prognostic and therapeutic approaches in which medical interventions are carried out based on individual patient characteristics. As life expectancy increases in developed and developing countries, the incidence of diseases such as cancer goes up among people in the community. Cancer is a disease that the response to treatment varies from one person to another and also it is costly for individuals, families, and society. Among thyroid cancers, anaplastic thyroid carcinoma (ATC) is the most aggressive, lethal and unresponsive form of the disease. Unfortunately, current drugs are not targetable, and therefore they have restricted role in ATC treatment. Consequently, mortality of this cancer, despite advances in the field of diagnosis and treatment, is one of the most important challenges in medicine. Cellular, molecular and genetic evidences play an important role in finding more effective diagnostic and therapeutic approaches. Review of these evidences confirms the application of personalized medicine in cancer treatment including ATC. A growing body of evidence has elucidated that cellular and molecular mechanisms of cancer would pave the way for defining new biomarkers for targeted therapy, taking into account individual differences. It should be noted that this approach requires further progress in the fields of basic sciences, pharmacogenetics and drug design. An overview of the most important aspects in individualized anaplastic thyroid cancer treatment will be discussed in this review.

    Using quantitative radiomics, we demonstrate that computer-extracted magnetic resonance (MR) image-based tumor phenotypes can be predictive of the molecular classification of invasive breast cancers. Radiomics analysis was performed on 91 MRIs of biopsy-proven invasive breast cancers from National Cancer Institute's multi-institutional TCGA/TCIA. Immunohistochemistry molecular classification was performed including estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, and for 84 cases, the molecular subtype (normal-like, luminal A, luminal B, HER2-enriched, and basal-like). Computerized quantitative image analysis included: three-dimensional lesion segmentation, phenotype extraction, and leave-one-case-out cross validation involving stepwise feature selection and linear discriminant analysis. The performance of the classifier model for molecular subtyping was evaluated using receiver operating characteristic analysis. The computer-extracted tumor phenotypes were able to distinguish between molecular prognostic indicators; area under the ROC curve values of 0.89, 0.69, 0.65, and 0.67 in the tasks of distinguishing between ER+ versus ER-, PR+ versus PR-, HER2+ versus HER2-, and triple-negative versus others, respectively. Statistically significant associations between tumor phenotypes and receptor status were observed. More aggressive cancers are likely to be larger in size with more heterogeneity in their contrast enhancement. Even after controlling for tumor size, a statistically significant trend was observed within each size group (P = 0.04 for lesions ≤ 2 cm; P = 0.02 for lesions >2 to ≤5 cm) as with the entire data set (P-value = 0.006) for the relationship between enhancement texture (entropy) and molecular subtypes (normal-like, luminal A, luminal B, HER2-enriched, basal-like).

    IMPORTANCE For patients with limited prognosis, some medication risks may outweigh the benefits, particularly when benefits take years to accrue; statins are one example. Data are lacking regarding the risks and benefits of discontinuing statin therapy for patients with limited life expectancy. OBJECTIVE To evaluate the safety, clinical, and cost impact of discontinuing statin medications for patients in the palliative care setting. DESIGN, SETTING, AND PARTICIPANTS This was a multicenter, parallel-group, unblinded, pragmatic clinical trial. Eligibility included adults with an estimated life expectancy of between 1 month and 1 year, statin therapy for 3 months or more for primary or secondary prevention of cardiovascular disease, recent deterioration in functional status, and no recent active cardiovascular disease. Participants were randomized to either discontinue or continue statin therapy and were monitored monthly for up to 1 year. The study was conducted from June 3, 2011, to May 2, 2013. All analyses were performed using an intent-to-treat approach. INTERVENTIONS Statin therapy was withdrawn from eligible patients who were randomized to the discontinuation group. Patients in the continuation group continued to receive statins. MAIN OUTCOMES AND MEASURES Outcomes included death within 60 days (primary outcome), survival, cardiovascular events, performance status, quality of life (QOL), symptoms, number of nonstatin medications, and cost savings. RESULTS A total of 381 patients were enrolled; 189 of these were randomized to discontinue statins, and 192 were randomized to continue therapy. Mean (SD) age was 74.1 (11.6) years, 22.0% of the participants were cognitively impaired, and 48.8% had cancer. The proportion of participants in the discontinuation vs continuation groups who died within 60 days was not significantly different (23.8% vs 20.3%; 90% CI, −3.5% to 10.5%; P = .36) and did not meet the noninferiority end point.

    Cancer patient navigators are increasingly present on the oncology health care team. The positive impact of navigation on cancer care is recognised, yet a clear understanding of what the patient navigator does and how he/she executes the role continues to emerge. This study aimed to understand cancer patients' perceptions of, and experiences with patient navigation, exploring how navigation may enhance the patient experience in an urban hospital setting where patients with varying needs are treated. A qualitative study using a constructionist approach was conducted. Fifteen colorectal cancer patients participated in semi-structured telephone interviews. Data were analyzed inductively and iteratively. Findings provide insight into two central aspects of cancer navigation: navigation as patient-centred coordination and explanation of clinical care, and navigation as individualised, holistic support. Within these themes, the key benefits of navigation from the patients' perspective were demystifying the system; ensuring comprehension, managing expectations; and, delivering patient-centred care. The navigator provided individualised and extended family support; a holistic approach; and, addressed emotional and psychological needs. These findings provide a means to operationalise and validate an emerging role description and competency framework for the cancer navigator who must identify and adapt to patients' varying needs throughout the cancer care continuum.

    Organic solvents are ubiquitous in occupational settings where they may contribute to risks for carcinogenesis. However, there is limited information on organic solvents as human breast carcinogens. We examined the relationship between occupational exposure to solvents and breast cancer in a prospective study of 47,661 women with an occupational history in the Sister Study cohort. Occupational solvent exposure was categorized using self-reported job-specific solvent use collected at baseline. Multivariable Cox regression analyses were used to assess breast cancer risk, adjusting for established breast cancer risk factors. A total of 1,798 women were diagnosed with breast cancer during follow-up, including 1,255 invasive cases. Overall the risk of invasive breast cancer was not associated with lifetime exposure to solvents [HR, 1.04; 95% confidence interval (CI), 0.88-1.24]. Parous women who worked with solvents before their first full-term birth had an increased risk of estrogen receptor-positive invasive breast cancer compared with women who never worked with solvents (HR, 1.39; 95% CI, 1.03-1.86). A significantly elevated risk for estrogen receptor-positive invasive breast cancer was associated with solvent exposure among clinical laboratory technologists and technicians (HR, 2.00; 95% CI, 1.07-3.73). Occupational exposure to solvents before first birth, a critical period of breast tissue differentiation, may result in increased vulnerability for breast cancer. Our findings suggest a need for future studies in this area to focus on exposure time windows and solvent types in different occupational settings.

    Under the SET Program Task 4 - Regional Turboprop/Turbofan Engine Advanced Combustor Study, a total of ten low-emissions combustion system concepts were evaluated analytically for three different gas turbine engine geometries and three different levels of oxides of nitrogen (NOx) reduction technology, using an existing AlliedSignal three-dimensional (3-D) Computational Fluid Dynamics (CFD) code to predict Landing and Takeoff (LTO) engine cycle emission values. A list of potential Barrier Technologies to the successful implementation of these low-NOx combustor designs was created and assessed. A trade study was performed that ranked each of the ten study configurations on the basis of a number of manufacturing and durability factors, in addition to emissions levels. The results of the trade study identified three basic NOx-emissions reduction concepts that could be incorporated in proposed follow-on combustor technology development programs aimed at demonstrating low-NOx combustor hardware. These concepts are: high-flow swirlers and primary orifices, fuel-preparation cans, and double-dome swirlers.

  5. Assessment of Greenland albedo variability from the advanced very high resolution radiometer Polar Pathfinder data set

    2001-12-01

    The advanced very high resolution radiometer Polar Pathfinder (APP) data set is used to examine the variability of the surface albedo over Greenland. Analysis of the APP albedo record from 1981 to 1998 show anomalously low albedo during 1995 and 1998 over most of the ice sheet as compared with the other years. The low albedo encountered during these years suggests that the ice sheet experienced considerable melt in 1995 and 1998, particularly near the western margin of the ice sheet. Conversely, anomalously high albedos were found in 1992 as a result of colder temperatures and hence less melt following the eruption of Mount Pinatubo. The relationship between the annual North Atlantic Oscillation (NAO) index and the mean summer albedo from all the stations reveals a positive correlation of 0.44 and a positive correlation of 0.55 for the southern part of the ice sheet. Therefore variations in the mean summer albedo over Greenland can, in part, be explained by variations in the NAO such that during periods of intensification of the normal mode of the NAO the mean summer albedo is above normal. Trend analysis reveals an overall downward trend in surface albedo from 1981 to 1998, which agrees with recent trends in melt and precipitation. However, the trend was found not to be statistically significant but rather influenced by the low albedo in recent years.

  20. The modern role of androgen deprivation therapy in the management of localised and locally advanced prostate cancer

    PubMed Central

    Gunner, Charlotte; Gulamhusein, Aziz; Rosario, Derek J

    2016-01-01

    Introduction: Approximately 50% of men diagnosed with prostate cancer will be exposed to androgen deprivation therapy (ADT) at some stage. The role of ADT in the management of metastatic disease has long been recognised, and its place in the management of localised and locally advanced disease has become clearer in the past few years. Nevertheless, concerns remain that some men might not benefit from ADT in earlier-stage disease. The purpose of the current article is to provide a brief narrative review of the role of ADT as part of a strategy of treatment with curative intent, concentrating mainly on key recent developments in the area. Methods: Narrative literature review of key publications in the English language relating to ADT in the management of localised and locally advanced prostate cancer. Results: In locally advanced and high-risk localised prostate cancer, the use of ADT in combination with radiotherapy improves disease-specific and overall survival. There is no evidence to support the use of ADT in the treatment of low-risk localised prostate cancer. There appears to be an increased risk of cardiovascular morbidity and mortality associated with luteinizing hormone-releasing hormone agonists, particularly in men with pre-existing cardiovascular disease, but the relevance of this in the adjuvant/neoadjuvant setting is currently unclear. Conclusions: Future studies should focus on identification of men who are at risk from cardiovascular complications associated with ADT and on the comparison of radiotherapy with ADT versus surgery in the management of localised and locally advanced prostate cancer, particularly with regards to men with pre-existing comorbidities.

    For patients with locally advanced rectal cancer (LARC) treated with preoperation chemoradiation (pCRT), identifying differentially expressed (DE) genes between non-responders and responders is a common approach for investigating mechanisms of chemoradiation resistance. However, some of such DE genes might be irrelevant to cancer itself but simply reflect the pharmacokinetic differences of the normal tissues. In this study, we adopted the RankComp algorithm to identify DE genes for each of LARC sample compared with its own normal state. Then, we identified genes with significantly different deregulation frequencies between the non-responders and responders, defined as cancer-related pCRT-response genes. Pathway enrichment and protein-protein interaction analyses showed that these genes specifically and intensively interacted with currently known effective genes of pCRT, involving in DNA replication, cell cycle and DNA repair. In contrast, after excluding the cancer-related pCRT-response genes, the other DE genes between non-responders and responders were enriched in many pathways of drug and protein metabolisms and transports, and interacted with both the known effective genes and pharmacokinetic genes. Hence, these two types of DE genes should be distinguished for investigating mechanisms of pCRT response in LARCs. PMID:27845363

    Gralla, Richard J; Thatcher, Nick

    2004-12-01

    There is increasing awareness of the need for accurate assessment of quality of life in patients with lung cancer who are on clinical trials and in patient management. Self-reported multidimensional, validated, quality-of-life instruments assess physical, functional, psychological, social, and spiritual dimensions associated with lung cancer and its treatment. Such validated instruments are now available and are being utilized more frequently in clinical trials assessing the value of particular anticancer therapies. Such findings may influence the treatment of choice for patients with non-small-cell lung cancer (NSCLC), particularly in the advanced-disease setting where survival benefits from current treatments are modest, and the majority of patients present with three or more symptoms. Recently, a number of studies assessing quality of life in NSCLC have been published providing more insight into the effects of the disease and its treatment on the patient's perspective. Quality-of-life instruments that include patient reported outcomes ("PROS") and quality-of-life and symptom assessment are the only way to evaluate this crucial aspect of cancer care. As an example, Fossella and colleagues reported notable findings from the largest prospective evaluation (the TAX 326 trial) of quality of life using validated instruments in patients with NSCLC who received chemotherapy. Patients who received a docetaxel plus platinum combination regimen reported modest benefits in both quality of life and in disease-related parameters, such as pain control, weight loss, and performance status, compared to patients randomly assigned to the combination of vinorelbine and cisplatin. Compliance with the PRO assessment was high, supporting the feasibility of prospective quality-of-life evaluations in NSCLC. Important goals include building on these results by including quality-of-life assessment in all major clinical trials, and demonstrating feasible ways to incorporate this evaluation

  4. Targeting monoamine oxidase A in advanced prostate cancer

    2010-01-01

    Purpose Inhibitors of monoamine oxidase A (MAOA), a mitochondrial enzyme that degrades neurotransmitters including serotonin and norepinephrine, are commonly used to treat neurological conditions including depression. Recently, we and others identified high expression of MAOA in normal basal prostatic epithelium and high-grade primary prostate cancer (PCa). In contrast, MAOA is low in normal secretory prostatic epithelium and low-grade PCa. An irreversible inhibitor of MAOA, clorgyline, induced secretory differentiation in primary cultures of normal basal epithelial cells and high-grade PCa. Furthermore, clorgyline inhibited several oncogenic pathways in PCa cells, suggesting clinical value of MAOA inhibitors as a pro-differentiation and anti-oncogenic therapy for high-risk PCa. Here, we extended our studies to a model of advanced PCa, VCaP cells, which were derived from castration-resistant metastatic PCa and express a high level of MAOA. Methods Growth of VCaP cells in the presence or absence of clorgyline was evaluated in vitro and in vivo. Gene expression changes in response to clorgyline were determined by microarray and validated by quantitative real-time polymerase chain reaction. Results Treatment with clorgyline in vitro inhibited growth and altered the transcriptional pattern of VCaP cells in a manner consistent with the pro-differentiation and anti-oncogenic effects seen in treated primary PCa cells. Src, beta-catenin, and MAPK oncogenic pathways, implicated in androgen-independent growth and metastasis, were significantly downregulated. Clorgyline treatment of mice bearing VCaP xenografts slowed tumor growth and induced transcriptome changes similar to those noted in vitro. Conclusion Our results support the possibility that anti-depressant drugs that target MAOA might find a new application in treating PCa. PMID:20204405

  5. Concept and Viability of Androgen Annihilation for Advanced Prostate Cancer

    PubMed Central

    2014-01-01

    There remains no standard of care for patients with a rising prostate-specific antigen (PSA) after radical prostatectomy or radiation therapy but who have no radiographic metastases, even though this is the second largest group of prostate cancer (CaP) patients in the United States. Androgen deprivation therapy (ADT) may cure some men with advanced CaP based on single institution series and a randomized clinical trial of immediate versus delayed ADT for men found to have pelvic lymph node metastasis at the time of radical prostatectomy. ADT may be more effective when initiated for minimal disease burden, which can be detected using PSA after radical prostatectomy or radiation therapy, and if more complete disruption of the androgen axis using newer agents decreases the chance that androgen-sensitive cells survive to adapt to a low androgen environment. Androgens may be “annihilated” sing simultaneously a luteinizing hormone releasing hormone (LHRH) antagonist or agonist to inhibit testicular production of testosterone, a cytochrome P45017A1 (CYP17A1) inhibitor to diminish metabolism of testosterone via the adrenal pathway and dihydrotestosterone (DHT) via the backdoor pathway, a 5α-reductase inhibitor to diminish testosterone reduction to DHT and backdoor metabolism of progesterone substrates to DHT, and a newer anti-androgen to compete better with DHT for the androgen receptor ligand-binding domain. Early initiation of androgen annihilation for induction as part of planned intermittent ADT should be safe, may reduce tumor burden below a threshold that allows eradication by the immune system, and may cure many men who have failed definitive local therapy.

    Nausea and vomiting are common and distressing symptoms in advanced cancer. Both are multifactorial and cause significant morbidity, nutritional failure, and reduced quality of life. Assessment includes a detailed history, physical examination and investigations for reversible causes. Assessment and management will be influenced by performance status, prognosis, and goals of care. Several drug classes are effective with some having the added benefit of multiple routes of administration. It is our institution's practice to recommend metoclopramide as the first drug with haloperidol as an alternative antiemetic. Dexamethasone should be used for patients with central nervous system metastases or bowel obstruction. If your patient is near death, empiric metoclopramide, haloperidol or chlorpromazine is used without further investigation. For patients with a better prognosis, we exclude reversible causes and use the same first-line antiemetics, metoclopramide and haloperidol. For those who do not respond to first-line single antiemetics, olanzapine is second line and ondansetron is third. Rarely do we use combination therapy or cannabinoids. Olanzapine as a single agent has a distinct advantage over antiemetic combinations. It improves compliance, reduces drug interactions and has several routes of administration. Antiemetics, anticholinergics, octreotide and dexamethasone are used in combination to treat bowel obstruction. In opiod-na'ive patients, we prefer haloperidol, glycopyrrolate and an opioid as the first-line treatment and add or substitute octreotide and dexamethasone in those who do not respond. Non-pharmacologic interventions (mechanical stents and percutaneous endoscopic gastrostomy tubes) are used when nausea is refractory to medical management or for home-going management to relieve symptoms, reduce drug costs and rehospitalization.

    Background: We conducted a phase 1 trial in patients with locally advanced cervical cancer by injecting 0.5 ml of the CK2-antagonist CIGB-300 in two different sites on tumours to assess tumour uptake, safety, pharmacodynamic activity and identify the recommended dose. Methods: Fourteen patients were treated with intralesional injections containing 35 or 70 mg of CIGB-300 in three alternate cycles of three consecutive days each before standard chemoradiotherapy. Tumour uptake was determined using 99Tc-radiolabelled peptide. In situ B23/nucleophosmin was determined by immunohistochemistry. Results: Maximum tumour uptake for CIGB-300 70-mg dose was significantly higher than the one observed for 35 mg: 16.1±8.9 vs 31.3±12.9 mg (P=0.01). Both, AUC24h and biological half-life were also significantly higher using 70 mg of CIGB-300 (P<0.001). Unincorporated CIGB-300 diffused rapidly to blood and was mainly distributed towards kidneys, and marginally in liver, lungs, heart and spleen. There was no DLT and moderate allergic-like reactions were the most common systemic side effect with strong correlation between unincorporated CIGB-300 and histamine levels in blood. CIGB-300, 70 mg, downregulated B23/nucleophosmin (P=0.03) in tumour specimens. Conclusion: Intralesional injections of 70 mg CIGB-300 in two sites (0.5 ml per injection) and this treatment plan are recommended to be evaluated in phase 2 studies. PMID:25880012

    A gap exists between cancer prevention research and its translation into community practice. Two strategies to reduce this gap are community-based participatory research (CBPR) and dissemination research. CBPR offers an avenue to engage academic and community partners, thereby providing mechanisms for joint learning and application of knowledge. Dissemination research examines the movement of evidence-based public health and clinical innovations to practice settings. While applying these approaches may reduce the gap between research and practice, the cancer prevention workforce may be inadequate in size, insufficiently trained, lack resources and incentives, or face structural barriers to effectively participate in CBPR and disseminate evidence-based research findings into practice. Information on translating cancer prevention information to communities and workforce implications was obtained from a panel of experts and through a review of the literature on CBPR and dissemination research. The expert panel and literature review identified major barriers to successfully conducting CBPR and dissemination research in community settings. Barriers included inadequate policies; insufficient networking and communication infrastructures; unsupportive research cultures, climates, and mindsets; inadequate researcher and practitioner education; and limited CBPR and dissemination research with adequate study designs. No specific estimates of the cancer prevention workforce were found; however, indirect evidence for a shortfall were identified. We recommend expanding CBPR training for academic and community partners; increasing funding for dissemination research and practice; supporting proven partnerships; and providing strategic coordination for government agencies, research institutions, nongovernmental organizations, and the private sector to foster better dissemination of information and integration of community-based cancer prevention and control programs and practices

    Given the success of targeted agents in specific populations it is expected that some degree of molecular biomarker testing will become standard of care for many, if not all, cancers. To facilitate this, cancer centers worldwide are experimenting with targeted "panel" sequencing of selected mutations. Recent advances in genomic technology enable the generation of genome-scale data sets for individual patients. Recognizing the risk, inherent in panel sequencing, of failing to detect meaningful somatic alterations, we sought to establish processes to integrate data from whole-genome analysis (WGA) into routine cancer care. Between June 2012 and August 2014, 100 adult patients with incurable cancers consented to participate in the Personalized OncoGenomics (POG) study. Fresh tumor and blood samples were obtained and used for whole-genome and RNA sequencing. Computational approaches were used to identify candidate driver mutations, genes, and pathways. Diagnostic and drug information were then sought based on these candidate "drivers." Reports were generated and discussed weekly in a multidisciplinary team setting. Other multidisciplinary working groups were assembled to establish guidelines on the interpretation, communication, and integration of individual genomic findings into patient care. Of 78 patients for whom WGA was possible, results were considered actionable in 55 cases. In 23 of these 55 cases, the patients received treatments motivated by WGA. Our experience indicates that a multidisciplinary team of clinicians and scientists can implement a paradigm in which WGA is integrated into the care of late stage cancer patients to inform systemic therapy decisions.

  12. Beyond first-line chemotherapy for advanced pancreatic cancer: An expanding array of therapeutic options?

    2014-01-01

    While an increasing number of therapeutic options are now available for the first-line treatment of locally advanced or metastatic pancreatic cancer, the optimal choice for treatment in the second-line setting and beyond is less well defined. A variety of cytotoxic agents, either alone or in combination, have been evaluated, although primarily in the context of small single-arm or retrospective studies. Most regimens have been associated with median progression-free survival rates in the range of 2-4 mo and overall survival rates between 4-8 mo, highlighting the very poor prognosis of patients who are candidates for such treatment. Targeted therapies studied in this chemotherapy-refractory setting, meanwhile, have produced even worse efficacy results. In the current article, we review the clinical evidence for treatment of refractory disease, primarily in patients who have progressed on front-line gemcitabine-based chemotherapy. In the process, we highlight the limitations of the available data to date as well as some of the challenges in designing appropriate clinical trials in this salvage setting, including how to select an appropriate control arm given the absence of a well-established reference standard, and the importance of incorporating predictive biomarkers and quality of life measures whenever possible into study design.

    A MESSAGE FROM ASCO'S PRESIDENT Nearly 40 years ago, President Richard Nixon signed the National Cancer Act, mobilizing the country's resources to make the “conquest of cancer a national crusade.” That declaration led to a major investment in cancer research that has significantly improved cancer prevention, treatment, and survival. As a result, two thirds of people diagnosed with cancer today will live at least 5 years after diagnosis, compared with just half in the 1970s. In addition, there are now more than 12 million cancer survivors in the United States—up from 3 million in 1971. Scientifically, we have never been in a better position to advance cancer treatment. Basic scientific research, fueled in recent years by the tools of molecular biology, has generated unprecedented knowledge of cancer development. We now understand many of the cellular pathways that can lead to cancer. We have learned how to develop drugs that block those pathways; increasingly, we know how to personalize therapy to the unique genetics of the tumor and the patient. Yet in 2008, 1.4 million people in the United States will still be diagnosed with cancer, and more than half a million will die as a result of the disease. Some cancers remain stubbornly resistant to treatment, whereas others cannot be detected until they are in their advanced, less curable stages. Biologically, the cancer cell is notoriously wily; each time we throw an obstacle in its path, it finds an alternate route that must then be blocked. To translate our growing basic science knowledge into better treatments for patients, a new national commitment to cancer research is urgently needed. However, funding for cancer research has stagnated. The budgets of the National Institutes of Health and the National Cancer Institute have failed to keep pace with inflation, declining up to 13% in real terms since 2004. Tighter budgets reduce incentives to support high-risk research that could have the largest payoffs. The

That declaration led to a major investment in cancer research that has significantly improved cancer prevention, treatment, and survival. As a result, two thirds of people diagnosed with cancer today will live at least 5 years after diagnosis, compared with just half in the 1970s. In addition, there are now more than 12 million cancer survivors in the United States--up from 3 million in 1971. Scientifically, we have never been in a better position to advance cancer treatment. Basic scientific research, fueled in recent years by the tools of molecular biology, has generated unprecedented knowledge of cancer development. We now understand many of the cellular pathways that can lead to cancer. We have learned how to develop drugs that block those pathways; increasingly, we know how to personalize therapy to the unique genetics of the tumor and the patient. Yet in 2008, 1.4 million people in the United States will still be diagnosed with cancer, and more than half a million will die as a result of the disease. Some cancers remain stubbornly resistant to treatment, whereas others cannot be detected until they are in their advanced, less curable stages. Biologically, the cancer cell is notoriously wily; each time we throw an obstacle in its path, it finds an alternate route that must then be blocked. To translate our growing basic science knowledge into better treatments for patients, a new national commitment to cancer research is urgently needed. However, funding for cancer research has stagnated. The budgets of the National Institutes of Health and the National Cancer Institute have failed to keep pace with inflation, declining up to 13% in real terms since 2004. Tighter budgets reduce incentives to support high-risk research that could have the largest payoffs. The most

    Background The National Cancer Institute’s Symptom Management and Health-Related Quality of Life Steering Committee held a clinical trials planning meeting (September 2011) to identify a core symptom set to be assessed across oncology trials for the purposes of better understanding treatment efficacy and toxicity and to facilitate cross-study comparisons. We report the results of an evidence-synthesis and consensus-building effort that culminated in recommendations for core symptoms to be measured in adult cancer clinical trials that include a patient-reported outcome (PRO). Methods We used a data-driven, consensus-building process. A panel of experts, including patient representatives, conducted a systematic review of the literature (2001–2011) and analyzed six large datasets. Results were reviewed at a multistakeholder meeting, and a final set was derived emphasizing symptom prevalence across diverse cancer populations, impact on health outcomes and quality of life, and attribution to either disease or anticancer treatment. Results We recommend that a core set of 12 symptoms—specifically fatigue, insomnia, pain, anorexia (appetite loss), dyspnea, cognitive problems, anxiety (includes worry), nausea, depression (includes sadness), sensory neuropathy, constipation, and diarrhea—be considered for inclusion in clinical trials where a PRO is measured. Inclusion of symptoms and other patient-reported endpoints should be well justified, hypothesis driven, and meaningful to patients. Conclusions This core set will promote consistent assessment of common and clinically relevant disease- and treatment-related symptoms across cancer trials. As such, it provides a foundation to support data harmonization and continued efforts to enhance measurement of patient-centered outcomes in cancer clinical trials and observational studies.

    Advanced thyroid carcinoma is an infrequent tumor entity with limited treatment possibilities until recently. The extraordinary improvement in the comprehension of genetic and molecular alterations involving the RAS/RAF/mitogen-activated protein kinase and phosphatidylinositide 3-kinase/Akt/mammalian target of rapamycin signaling and interacting pathways that are involved in tumor survival, proliferation, differentiation, motility and angiogenesis have been the rationale for the development of new effective targeted therapies. Data coming from phase II clinical trials have confirmed the efficacy of those targeted agents against receptors in cell membrane and cytoplasmic molecules. Moreover, four of those investigational drugs, vandetanib, cabozantinib, sorafenib and lenvatinib, have reached a phase III clinical trial with favorable results in progression-free survival and overall survival in medullary thyroid carcinoma and differentiated thyroid carcinoma. Further analysis for an optimal approach has been conducted according to mutational profile and tumor subtypes. However, consistent results are still awaited and the research for adequate prognostic and predictive biomarkers is ongoing. The following report offers a comprehensive review from the rationale to the basis of targeted agents in the treatment of thyroid carcinoma. In addition, current and future therapeutic developments by the inhibition of further molecular targets are discussed in this setting. PMID:25553081

    In lung cancer, outcome measurement has been mostly limited to survival. Proper assessment of the value of lung cancer treatments, and the performance of institutions delivering care, requires more comprehensive measurement of standardised outcomes. The International Consortium for Health Outcomes Measurement convened an international, multidisciplinary working group of patient representatives, medical oncologists, surgeons, radiation oncologists, pulmonologists, palliative care specialists, registry experts and specialist nurses to review existing data and practices. Using a modified Delphi method, the group developed a consensus recommendation (“the set”) on the outcomes most essential to track for patients with lung cancer, along with baseline demographic, clinical and tumour characteristics (case-mix variables) for risk adjustment. The set applies to patients diagnosed with nonsmall cell lung cancer and small cell lung cancer. Our working group recommends the collection of the following outcomes: survival, complications during or within 6 months of treatment and patient-reported domains of health-related quality of life including pain, fatigue, cough and dyspnoea. Case-mix variables were defined to improve interpretation of comparisons. We defined an international consensus recommendation of the most important outcomes for lung cancer patients, along with relevant case-mix variables, and are working to support adoption and reporting of these measures globally.

    Background Health utilities are increasingly incorporated in health economic evaluations. Different elicitation methods, direct and indirect, have been established in the past. This study examined the evidence on health utility elicitation previously reported in advanced/metastatic breast cancer and aimed to link these results to requirements of reimbursement bodies. Methods Searches were conducted using a detailed search strategy across several electronic databases (MEDLINE, EMBASE, Cochrane Library, and EconLit databases), online sources (Cost-effectiveness Analysis Registry and the Health Economics Research Center), and web sites of health technology assessment (HTA) bodies. Publications were selected based on the search strategy and the overall study objectives. Results A total of 768 publications were identified in the searches, and 26 publications, comprising 18 journal articles and eight submissions to HTA bodies, were included in the evidence review. Most journal articles derived utilities from the European Quality of Life Five-Dimensions questionnaire (EQ-5D). Other utility measures, such as the direct methods standard gamble (SG), time trade-off (TTO), and visual analog scale (VAS), were less frequently used. Several studies described mapping algorithms to generate utilities from disease-specific health-related quality of life (HRQOL) instruments such as European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 30 (EORTC QLQ-C30), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Breast Cancer 23 (EORTC QLQ-BR23), Functional Assessment of Cancer Therapy – General questionnaire (FACT-G), and Utility-Based Questionnaire-Cancer (UBQ-C); most used EQ-5D as the reference. Sociodemographic factors that affect health utilities, such as age, sex, income, and education, as well as disease progression, choice of utility elicitation method, and country settings, were identified

    The era of "Big Data" presents opportunities to substantively address cancer prevention and control issues by improving health behaviors and refining theoretical models designed to understand and intervene in those behaviors. Yet, the terms "model" and "Big Data" have been used rather loosely, and clarification of these terms is required to advance the science in this area. The objectives of this paper are to discuss conceptual definitions of the terms "model" and "Big Data", as well as examine the promises and challenges of Big Data to advance cancer prevention and control research using behavioral theories. Specific recommendations for harnessing Big Data for cancer prevention and control are offered.

    One of the rare but most challenging issues in the management of the locally-advanced breast cancer (LABC) is life-threatening bleeding from the fungating and/or ulcerating focus (foci) of these tumors. Breast surgeons may need the assistance of interventional radiologists to solve this urgent condition if surgery cannot provide sufficient benefit. Herein, we report a case of recurrent locally-advanced breast cancer that presented with sudden severe bleeding, which was stopped by an interventional radiologist via transcatheter arterial embolization (TAE). In addition, we evaluate the role of interventional radiology in patients with breast cancer who present with bleeding from the breast by reviewing the relevant literature.

    Osteoprotective therapies have become an essential component in the management of advanced prostate cancer (PC) patients as bone metastases (BMs) have a major impact on morbidity and mortality. Denosumab is a fully humanized antibody targeting the receptor activator of nuclear factor κB ligand (RANKL), which has been approved by the European Medicines Agency (EMA) in Europe and the United States (US) Food and Drug Administration (FDA) in the US for prevention of skeletal-related events (SREs) in patients with solid tumors and BMs, including PC. The clinical settings in which PC patients should be treated with denosumab are still discussed controversially. In a phase III study, denosumab significantly delayed SREs compared with zoledronic acid (ZA) in patients with metastatic castration-resistant PC (CRPC). In addition, denosumab showed superior effects on pain and health-related quality of life (QoL) in these patients. In patients with nonmetastatic CRPC, denosumab has been proven to significantly increase bone metastases-free survival. However, no significant benefits on cancer-specific and overall survival were observed and denosumab was not approved by the US FDA and EMA in this context. The effectiveness of denosumab in patients with castration-sensitive PC (CSPC) and BMs is also under discussion, as clinical trials with ZA in these patients have not shown significant benefits. Clinical data on the use of denosumab in CSPC are urgently needed. PMID:28392837

    We retrospectively review outcomes of applying boron neutron capture therapy (BNCT) to unresectable advanced or recurrent head and neck cancers. Patients who were treated with BNCT for either local recurrent or newly diagnosed unresectable head or neck cancers between December 2001 and September 2007 were included. Clinicopathological characteristics and clinical outcomes were retrieved from hospital records. Either a combination of borocaptate sodium and boronophenylalanine (BPA) or BPA alone were used as boron compounds. In all the treatment cases, the dose constraint was set to deliver a dose <10-12 Gy-eq to the skin or oral mucosa. There was a patient cohort of 62, with a median follow-up of 18.7 months (range, 0.7-40.8). A total of 87 BNCT procedures were performed. The overall response rate was 58% within 6 months after BNCT. The median survival time was 10.1 months from the time of BNCT. The 1- and 2-year overall survival (OS) rates were 43.1% and 24.2%, respectively. The major acute Grade 3 or 4 toxicities were hyperamylasemia (38.6%), fatigue (6.5%), mucositis/stomatitis (9.7%) and pain (9.7%), all of which were manageable. Three patients died of treatment-related toxicity. Three patients experienced carotid artery hemorrhage, two of whom had coexistent infection of the carotid artery. This study confirmed the feasibility of our dose-estimation method and that controlled trials are warranted.

    Cervical cancer (CC) mortality is a major public health concern since it is the second cause of cancer-related deaths among women. Patients diagnosed with locally advanced CC (LACC) have an important rate of recurrence and treatment failure. Conventional treatment for LACC is based on chemotherapy and radiotherapy; however, up to 40% of patients will not respond to conventional treatment; hence, we searched for a prognostic gene signature able to discriminate patients who do not respond to the conventional treatment employed to treat LACC. Tumor biopsies were profiled with genome-wide high-density expression microarrays. Class prediction was performed in tumor tissues and the resultant gene signature was validated by quantitative reverse transcription–polymerase chain reaction. A 27-predictive gene profile was identified through its association with pathologic response. The 27-gene profile was validated in an independent set of patients and was able to distinguish between patients diagnosed as no response versus complete response. Gene expression analysis revealed two distinct groups of tumors diagnosed as LACC. Our findings could provide a strategy to select patients who would benefit from neoadjuvant radiochemotherapy-based treatment. PMID:25926073

    Pancreatic cancer remains associated with an extremely poor prognosis. Surgical resection can be curative, but the majority of patients present with locally advanced or metastatic disease. Treatment for patients with locally advanced disease is controversial. Therapeutic options include systemic therapy alone, concurrent chemoradiation, or induction chemotherapy followed by chemoradiation. We review the evidence to date regarding the treatment of locally advanced pancreatic cancer (LAPC), as well as evolving strategies including the emerging role of targeted therapies. We propose that if radiation is used for patients with LAPC, it should be delivered with concurrent chemotherapy and following a period of induction chemotherapy.

    Eifler, Tim

    The recent ESA/NASA Planck mission has provided a key data set to constrain cosmology that is most sensitive to physics of the early Universe, such as inflation and primordial NonGaussianity (Planck 2015 results XIII). In combination with cosmological probes of the LargeScale Structure (LSS), the Planck data set is a powerful source of information to investigate late time phenomena (Planck 2015 results XIV), e.g. the accelerated expansion of the Universe, the impact of baryonic physics on the growth of structure, and the alignment of galaxies in their dark matter halos. It is the main objective of this proposal to re-analyze the archival Planck data, 1) with different, more recently developed statistical methods for cosmological parameter inference, and 2) to combine Planck and ground-based observations in an innovative way. We will make the corresponding analysis framework publicly available and believe that it will set a new standard for future CMB-LSS analyses. Advanced statistical methods, such as the Gibbs sampler (Jewell et al 2004, Wandelt et al 2004) have been critical in the analysis of Planck data. More recently, Approximate Bayesian Computation (ABC, see Weyant et al 2012, Akeret et al 2015, Ishida et al 2015, for cosmological applications) has matured to an interesting tool in cosmological likelihood analyses. It circumvents several assumptions that enter the standard Planck (and most LSS) likelihood analyses, most importantly, the assumption that the functional form of the likelihood of the CMB observables is a multivariate Gaussian. Beyond applying new statistical methods to Planck data in order to cross-check and validate existing constraints, we plan to combine Planck and DES data in a new and innovative way and run multi-probe likelihood analyses of CMB and LSS observables. The complexity of multiprobe likelihood analyses scale (non-linearly) with the level of correlations amongst the individual probes that are included. For the multi

    Despite advancements in therapy for advanced gastric and gastroesophageal junction cancers, their prognosis remains dismal. Tumor angiogenesis plays a key role in cancer growth and metastasis, and recent studies indicate that pharmacologic blockade of angiogenesis is a promising approach to therapy. In this systematic review, we summarize current literature on the clinical benefit of anti-angiogenic agents in advanced gastric cancer. We conducted a systematic search of PubMed and conference proceedings including the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress. Included studies aimed to prospectively evaluate the efficacy and safety of anti-angiogenic agents in advanced gastric or gastroesophageal junction cancer. Each trial investigated at least one of the following endpoints: overall survival, progression-free survival/time to progression, and/or objective response rate. Our search yielded 139 publications. Forty-two met the predefined inclusion criteria. Included studies reported outcomes with apatinib, axitinib, bevacizumab, orantinib, pazopanib, ramucirumab, regorafenib, sorafenib, sunitinib, telatinib, and vandetanib. Second-line therapy with ramucirumab and third-line therapy with apatinib are the only anti-angiogenic agents so far shown to significantly improve survival of patients with advanced gastric cancer. Overall, agents that specifically target the vascular endothelial growth factor ligand or receptor have better safety profile compared to multi-target tyrosine kinase inhibitors.

    The cloning of the breast cancer susceptibility genes BRCA1 and BRCA2 nearly two decades ago helped set in motion an avalanche of research exploring how genomic information can be optimally applied to identify and clinically care for individuals with a high risk of developing cancer. Genetic testing for mutations in BRCA1, BRCA2, and other breast cancer susceptibility genes has since proved to be a valuable tool for determining eligibility for enhanced screening and prevention strategies, as well as for identifying patients most likely to benefit from a targeted therapy. Here, we discuss the landscape of inherited mutations and sequence variants in BRCA1 and BRCA2, the complexities of determining disease risk when the pathogenicity of sequence variants is uncertain, and current strategies for clinical management of women who carry BRCA1/2 mutations.

    . Conclusions and future directions Technical expertise to enable the delivery of high quality RT to complex target volumes as is required in gastric cancer, and surgical standards to ensure the delivery of high quality surgery, have matured in recent years. Six trials with large sample sizes are currently ongoing to better define the role of preoperative CRT (two studies) and postoperative CRT (four studies), when used in conjunction with high quality surgery and RT, and contemporary CT regimens. The moderate likelihood of locoregional recurrences and the favorable therapeutic ratio with using RT preoperatively in other settings, provide optimism that preoperative CRT would have a pivotal role to play in locally advanced gastric cancer. Active accrual into ongoing trials is strongly encouraged. PMID:25642342

    This integrative literature review aimed to characterize scientific articles on health-related quality of life - HRQoL - among patients with advanced cancer from national and international literature, and summarize those factors evidenced in the literature that contributed to the improvement or worsening of HRQoL among patients with advanced cancer. The search for materials was conducted in the following databases: CINAHL, EMBASE, PubMed, SciELO and LILACS. Among the 21 articles in the sample, 13 showed an improvement of HRQoL among patients with advanced cancer related to the development of physical, emotional and spiritual interventions. In eight studies, we identified predictive symptoms of low HRQoL, such as pain, fatigue, sleep disorders, depression, nutritional changes, and others. The results showed that clinical manifestations, which many times were inherent in cancer, such as factors that can lower patients' HRQoL, while physical, psychological and spiritual benefits resulting from therapeutic interventions may promote its improvement.

    Head and neck cancers usually present with advanced disease and novel therapies are urgently needed. Genetic therapy aims at restoring malfunctioned tumor suppressor gene(s) or introducing proapoptotic genes. Oncolytic virotherapeutics induce multiple cycles of cancer-specific virus replication, followed by oncolysis, virus spreading and infection of adjacent cancer cells. Oncolytic viruses can also be armed to express therapeutic transgene(s). Recent advances in preclinical and clinical studies are revealing the potential of both therapeutic classes for advanced head and neck cancers, including the approval of two products (Gendicine and H101) by a governmental agency. This review summarizes the available clinical data to date and discusses the challenges and future directions.

    Previous precision medicine studies have investigated conventional molecular techniques and/or limited sets of gene alterations. The aim of this study was to describe the impact of the next-generation sequencing of the largest panel of genes used to date in tumour tissue and blood in the context of institutional molecular screening programmes. DNA analysis was performed by next-generation sequencing using a panel of 426 cancer-related genes and by comparative genomic hybridization from formalin-fixed and paraffin-embedded archived tumour samples when available or from fresh tumour samples. Five hundred sixty-eight patients were enrolled. The median number of prior lines of treatment was 2 (range 0-9). The most common primary tumour types were lung (16.9%), colorectal (14.4%), breast (10.6%), ovarian (10.2%) and sarcoma (10.2%). The median patient age was 63 years (range 19-88). A total of 292 patients (51.4%) presented with at least one actionable genetic alteration. The 20 genes most frequently altered were TP53, CDKN2A, KRAS, PTEN, PI3KCA, RB1, APC, ERBB2, MYC, EGFR, CDKN2B, ARID1A, SMAD4, FGFR1, MDM2, BRAF, ATM, CCNE1, FGFR3 and FRS2. One hundred fifty-nine patients (28%) were included in early phase trials. The treatment was matched with a tumour profile in 86 cases (15%). The two main reasons for non-inclusion were non-progressive disease (31.5%) and general status deterioration (25%). Twenty-eight percent of patients presented with a growth modulation index (time to progression under the early phase trial treatment/time to progression of the previous line of treatment) >1.3.Extensive molecular profiling using high-throughput techniques allows for the identification of actionable mutations in the majority of cases and is associated with substantial clinical benefit in up to one in four patients.

    Prostate cancer is the most common cancer occurring in American men of all races. It is also the second leading cause of cancer death among men in the USA. Bone metastasis is a frequent occurrence in men with advanced prostate cancer, with skeletal-related events being a common complication and having negative consequences, leading to severe pain, increased health care costs, increased risk of death, and decreased quality of life for patients. Bone loss can also result from antiandrogen therapy, which can further contribute to skeletal-related events. Treatment with antiresorptive agents bisphosphonates, and the newly approved denosumab, a receptor activator of nuclear factor kappa-B ligand (RANK-L) inhibitor, has been shown to reduce the risk of skeletal-related complications and prevent treatment-induced bone loss in patients with advanced prostate cancer. This review discusses the role of antiresorptive agents bisphosphonates and RANK-L inhibitor in the current treatment of advanced prostate cancer by examining the primary literature and also focuses on the likely role of the bisphosphonates in the treatment of advanced prostate cancer in the future.

    Anaplastic lymphoma kinase (alk) is an oncogenic driver in non-small-cell lung cancer (nsclc). Chromosomal rearrangements involving the ALK gene occur in up to 4% of nonsquamous nsclc patients and lead to constitutive activation of the alk signalling pathway. ALK-positive nsclc is found in relatively young patients, with a median age of 50 years. Patients frequently have brain metastasis. Targeted inhibition of the alk pathway prolongs progression-free survival in patients with ALK-positive advanced nsclc. The results of several recent clinical trials confirm the efficacy and safety benefit of crizotinib and ceritinib in this population. Canadian oncologists support the following consensus statement: All patients with advanced nonsquamous nsclc (excluding pure neuroendocrine carcinoma) should be tested for the presence of an ALK rearrangement. If an ALK rearrangement is present, treatment with a targeted alk inhibitor in the first-line setting is recommended. As patients become resistant to first-generation alk inhibitors, other treatments, including second-generation alk inhibitors can be considered. PMID:27330348

    Worldwide ovarian cancer affects over 200,000 women per year. Overall survival rates are poor due to two predominate reasons. First, the majority of patients present with advanced disease creating significant difficulty with effecting disease eradication. Second, acquisition of chemotherapy resistance results in untreatable progressive disease. Advances in treatment of advanced ovarian cancer involve a spectrum of interventions including improvements in frontline debulking surgery and combination chemotherapy. Anti-angiogenic factors have been shown to have activity in frontline and recurrent disease while novel chemotherapeutic agents and targeted treatments are in development particularly for disease that is resistant to platinum-based chemotherapy. These developments aim to improve the progression-free and overall survival of women with advanced ovarian cancer.

    AIM: To investigate the efficacy and safety of cape-citabine plus irinotecan ± bevacizumab in advanced or metastatic colorectal cancer patients. METHODS: Forty six patients with previously untreated, locally-advanced or metastatic colorectal cancer (mCRC) were recruited between 2001-2006 in a prospective open-label phase II trial, in German community-based outpatient clinics. Patients received a standard capecitabine plus irinotecan (CAPIRI) or CAPIRI plus bevacizumab (CAPIRI-BEV) regimen every 3 wk. Dose reductions were mandatory from the first cycle in cases of > grade 2 toxicity. The treatment choice of bevacizumab was at the discretion of the physician. The primary endpoints were response and toxicity and secondary endpoints included progression-free survival and overall survival. RESULTS: In the CAPIRI group vs the CAPRI-Bev group there were more female than male patients (47% vs 24%), and more patients had colon as the primary tumor site (58.8% vs 48.2%) with fewer patients having sigmoid colon as primary tumor site (5.9% vs 20.7%). Grade 3/4 toxicity was higher with CAPIRI than CAPIRI-Bev: 82% vs 58.6%. Partial response rates were 29.4% and 34.5%, and tumor control rates were 70.6% and 75.9%, respectively. No complete responses were observed. The median progression-free survival was 11.4 mo and 12.8 mo for CAPIRI and CAPIRI-Bev, respectively. The median overall survival for CAPIRI was 15 mo (458 d) and for CAPIRI-Bev 24 mo (733 d). These differences were not statistically different. In the CAPIRI-Bev, group, two patients underwent a full secondary tumor resection after treatment, whereas in the CAPIRI group no cases underwent this procedure. CONCLUSION: Both regimens were well tolerated and offered effective tumor growth control in this outpatient setting. Severe gastrointestinal toxicities and thromboembolic events were rare and if observed were never fatal. PMID:19152449

    Background: Early palliative care is increasingly recommended but seldom practised. We sought to examine perceptions of palliative care among patients with advanced cancer and their caregivers. Methods: After conducting a cluster randomized controlled trial of early palliative care versus standard care for patients with advanced cancer, we approached patients and their caregivers to participate in semistructured interviews seeking to assess, qualitatively, their attitudes and perceptions about palliative care. We used the grounded theory method for data collection and analysis. Results: A total of 48 patients (26 intervention, 22 control) and 23 caregivers (14 intervention, 9 control) completed interviews. Participants’ initial perceptions of palliative care in both trial arms were of death, hopelessness, dependency and end-of-life comfort care for inpatients. These perceptions provoked fear and avoidance, and often originated from interactions with health care professionals. During the trial, those in the intervention arm developed a broader concept of palliative care as “ongoing care” that improved their “quality of living” but still felt that the term itself carried a stigma. Participants in the intervention group emphasized the need for palliative care to be reframed and better explained by health care professionals. Participants in the control group generally considered it pointless to rename palliative care, but many in the intervention group stated emphatically that a different name was necessary in the early outpatient setting. Interpretation: There is a strong stigma attached to palliative care, which may persist even after positive experiences with an early palliative care intervention. Education of the public, patients and health care providers is paramount if early integration of palliative care is to be successful. PMID:27091801

    Breast cancer incidence and mortality rates are similar in low resource settings like Tanzania. Structural and sociocultural barriers make late presentation typical in such settings where treatment options for advanced stage disease are limited. In the absence of national programmes, stand-alone screening campaigns tend to employ clinical models of delivery focused on individual behaviour and through a disease specific lens. This paper describes a case study of a 2010 stand-alone campaign in Tanzania to argue that exclusively clinical approaches can undermine screening efforts by premising that women will act outside their social and cultural domain when responding to screening services. A focus on sociocultural barriers dictated the approach and execution of the intervention. Our experience concurs with that in similar settings elsewhere, underscoring the importance of barriers situated within the sociocultural milieu of societies when considering prevention interventions. Culturally competent delivery could contribute to long-term reductions in late stage presentation and increases in treatment acceptance. We propose a paradigm shift in the approach to stand-alone prevention programmes.

    Cancer is a complex disease that cannot be diagnosed reliably using only single gene expression analysis. Using gene-set analysis on high throughput gene expression profiling controlled by various environmental factors is a commonly adopted technique used by the cancer research community. This work develops a comprehensive gene expression analysis tool (gene-set activity toolbox: (GAT)) that is implemented with data retriever, traditional data pre-processing, several gene-set analysis methods, network visualization and data mining tools. The gene-set analysis methods are used to identify subsets of phenotype-relevant genes that will be used to build a classification model. To evaluate GAT performance, we performed a cross-dataset validation study on three common cancers namely colorectal, breast and lung cancers. The results show that GAT can be used to build a reasonable disease diagnostic model and the predicted markers have biological relevance. GAT can be accessed from http://gat.sit.kmutt.ac.th where GAT's java library for gene-set analysis, simple classification and a database with three cancer benchmark datasets can be downloaded.

    The objective of this study was to investigate the prognostic value of pretreatment NLR and its dynamic changes responsive to palliative care in advanced cancer patients. The study was retrospectively assessed in 378 consecutive advanced cancer patients receiving palliative care, and in an extended follow-up study of 106 of those patients. The cutoff value of pretreatment NLR was determined to be 3.0. In the 378 advanced cancer patients, 89 had pretreatment NLR ≤ 3, and 289 had an NLR > 3. Univariate and multivariate analyses showed that tumor stage, palliative care, albumin level, and pretreatment NLR (HR: 1.514, 95% CI: 1.125~2.038, P = 0.006) were independent prognostic indicators of OS. Moreover, in the follow-up cohort of 106 readmitted patients, 43 patients achieved a decreased NLR after palliative care, while the remaining 63 patients showed an increased NLR. Univariate and multivariate analyses showed that an increase in NLR was significantly associated with a poor survival (HR: 2.506, 95% CI: 1.474~4.261, P = 0.001). In conclusion, pretreatment NLR and changes in NLR independently predicted OS in advanced cancer patients undergoing palliative care. Incorporating NLR into clinical practice may better inform the prognosis and therapy decisions of advanced cancer patients in palliative settings. PMID:27510632

    The adult oncology inpatient music therapy program at Peter MacCallum Cancer Center, which is Australia's only hospital solely dedicated to cancer treatment, research and care, is described. Patients' treatment requirements and often changing conditions compel music therapist to be flexible in their approach, offering both pre-planned treatment sessions and spontaneous sessions in open ward contexts. Patients and families who wish to engage im music therapy choose from various music therapy methods, including live song choice, music imagery and relaxation, therapeutic music lessons, and improvisation. Complex variables inevitable in such human relationship therapies necessitate that, alongside randomized controlled trials, research methods are grounded in the social sciences to meaningfully substantiate, and further advance, oncologic music therapy.

    Recent advances in understanding the mechanisms underlying the development and progression of castration resistant prostate cancer from androgen-sensitive prostate cancer have provided new avenues exploring efficacious therapies in a disease which is the second leading cause of cancer deaths among men in the western world. In the evolution of second generation anti-androgens, enzalutamide, a novel androgen-receptor signaling inhibitor, has emerged targeting multiple steps within the androgenic stimulation pathway. This review discusses what is currently known of the mechanisms surrounding castration resistant prostate cancer development and the current human clinical trials to determine whether enzalutamide presents a new hope for men with advanced prostate cancer. The issues of therapy resistance, withdrawal effects and cross-resistance are briefly touched upon. PMID:26109877

    The importance of physical activity for chronic disease prevention and management has become generally well accepted. The number of research interventions and publications examining the benefits of physical activity for patients with cancer has been rising steadily. However, much of that research has focused on the impact of physical activity either prior to or early in the cancer diagnosis, treatment, and survivorship process. Research focusing on the effects of physical activity, specifically for patients with advanced-stage cancer and poorer prognostic outcomes, has been addressed only recently. The purpose of this article is to examine the state of the science for physical activity in the advanced-stage disease subset of the cancer population. Exercise in a variety of intensities and forms, including yoga, walking, biking, and swimming, has many health benefits for people, including those diagnosed with cancer. Research has shown that, for people with cancer (including advanced-stage cancer), exercise can decrease anxiety, stress, and depression while improving levels of pain, fatigue, shortness of breath, constipation, and insomnia. People diagnosed with cancer should discuss with their oncologist safe, easy ways they can incorporate exercise into their daily lives.

    Improvement of cell purification and transplantation techniques have contributed to the identification of cell populations known as tumor-initiating cells (TICs). Although it was hypothesized that tumors are organized as hierarchies of tumor cells that are sustained by rare TICs, like normal tissue stem cells, there are several controversies towards such cancer stem cell model, e.g. reversible change of stem cell like population based on epigenetic changes, clonal genetic evolution and problems in xenotransplantation system. Despite complexity in cancer stem cell models, studies in cancer stem cell field have revealed that there are close relationship between cancer malignancy and stem cell properties, called "stemness". Understanding molecular mechanisms for controlling stemness would contribute to establishment of novel diagnostics or therapeutics for cancer.

    Conflicting evidence on the carcinogenicity of diesel exhaust (DE) and coal mine dust in occupational settings exist. Exposure measurement in most studies is inferred on the basis of job classifications and may lead to misclassification. Confounding behavioral factors (i.e., smoking) and occupational risk factors (exposure to asbestos, arsenic, radon) need to be considered. We evaluated the epidemiological evidence and current findings of the carcinogenicity of DE and coal mine dust in occupational settings. Pertaining literature was identified through Medline search and recent review articles. Strengths and limitations of recent approaches are discussed. Many epidemiological studies have addressed the question of carcinogenicity in workers exposed to DE, and most showed a low-to-medium increase in the risk of bronchial carcinoma. The pooled relative risk (RR) estimates lie between 1.33 and 1.47, and a consistent rise in risk across various job categories and study designs point to a causal relationship. Data on the carcinogenicity of coal mine dust are less consistent and the potential for confounding by unmeasured risk factors (arsenic, radon, DE) are higher. While silica as one of its components has been evaluated as carcinogenic, there is inadequate evidence for the carcinogenicity of pure coal dust according to the International Agency for Research on Cancer (IARC). There is sufficient evidence for a causal relationship between DE and lung cancer in occupational settings. The evidence for coal mine dust is less convincing, but individual studies show an increase in risk of lung cancer in exposed workers. 4 refs.

    Background Distant recurrences after antineoplastic treatment remain a serious problem for breast cancer clinical management, which threats patients’ life. Systemic therapy is administered to eradicate cancer cells from the organism, both at the site of the primary tumor and at any other potential location. Despite this intervention, a significant proportion of breast cancer patients relapse even many years after their primary tumor has been successfully treated according to current clinical standards, evidencing the existence of a chemoresistant cell subpopulation originating from the primary tumor. Methods/Findings To identify key molecules and signaling pathways which drive breast cancer chemoresistance we performed gene expression analysis before and after anthracycline and taxane-based chemotherapy and compared the results between different histopathological response groups (good-, mid- and bad-response), established according to the Miller & Payne grading system. Two cohorts of 33 and 73 breast cancer patients receiving neoadjuvant chemotherapy were recruited for whole-genome expression analysis and validation assay, respectively. Identified genes were subjected to a bioinformatic analysis in order to ascertain the molecular function of the proteins they encode and the signaling in which they participate. High throughput technologies identified 65 gene sequences which were over-expressed in all groups (P ≤ 0·05 Bonferroni test). Notably we found that, after chemotherapy, a significant proportion of these genes were over-expressed in the good responders group, making their tumors indistinguishable from those of the bad responders in their expression profile (P ≤ 0.05 Benjamini-Hochgerg`s method). Conclusions These data identify a set of key molecular pathways selectively up-regulated in post-chemotherapy cancer cells, which may become appropriate targets for the development of future directed therapies against breast cancer.

    BACKGROUND The effect of care setting on value of colon cancer care is unknown. METHODS A Surveillance, Epidemiology, and End Results (SEER)-Medicare cohort study of 6544 patients aged ≥66 years with stage IV colon cancer (based on the American Joint Committee on Cancer staging system) who were diagnosed between 1996 and 2005 was performed. All patients were followed through December 31, 2007. Using outpatient and carrier claims, patients were assigned to a treating hospital based on the hospital affiliation of the primary oncologist. Hospitals were classified academic or nonacademic using the SEER-Medicare National Cancer Institute Hospital File. RESULTS Of the 6544 patients, 1605 (25%) received care from providers affiliated with academic medical centers. The unadjusted median cancer-specific survival was 16.0 months at academic medical centers versus 13.9 months at nonacademic medical centers (P<.001). After adjustment, treatment at academic hospitals remained significantly associated with a reduced risk of death from cancer (hazard ratio, 0.87; 95% confidence interval [95% CI], 0.82–0.93 [P<.001]). Adjusted mean 12-month Medicare spending was $8571 higher at academic medical centers (95% CI, $2340–$14,802; P =.007). The adjusted median cost was $1559 higher at academic medical centers; this difference was not found to be statistically significant (95% CI, −$5239 to $2122; P =.41). A small percentage of patients who received very expensive care skewed the difference in mean cost; the only statistically significant difference in adjusted costs in quantile regressions was at the 99.9th percentile of costs (P<.001). CONCLUSIONS Among Medicare beneficiaries with stage IV colon cancer, treatment by a provider affiliated with an academic medical center was associated with a 2 month improvement in overall survival. Except for patients in the 99.9th percentile of the cost distribution, costs at academic medical centers were not found to be significantly

    Breast cancer is a malignant tumor from normal breast epithelial. In recent years, many literature reports sought to determine the expression of predicted target genes of microRNA and their potential function, pathways and networks, which are involved in the tumorigenesis, metastasis and prognosis of breast cancer. The miR-21 has recently been found to be highly expressed in solid tumors than normal tissue, and it has exposed some layers of gene expression regulation that becomes a hot topic of breast cancer. This paper briefly reviews advances in research on miR-21 in breast cancer.

    Cancer is one of the most common devastating disease affecting millions of people per year worldwide. To fight against cancer, a number of natural plant compounds have been exploited by researchers to discover novel anti-cancer therapeutics with minimum or no side effects and plants have proved their usefulness in anti-cancer therapy in past few years. Ricin, a cytotoxic plant protein isolated from castor bean seeds, is a ribosome-inactivating protein which destroys the cells by inhibiting proteins synthesis. Ricin presents great potential as anti-cancer agent and exerts its anti-cancer activity by inducing apoptosis in cancer cells. In this review, we summarize the current information on anti-cancer properties of plant toxin ricin, its potential applications in cancer therapy, challenges associated with its use as therapeutic agent and the recent advances made to overcome these challenges. Nanotechnology could open the doors for quick development of ricin-based anti-cancer therapeutics. Conceivably, ricin may serve as a chemotherapeutic agent against cancer by utilizing nanocarriers for its targeted delivery to cancer cells.

    There are no simple solutions to difficult ethical problems. Advance directives, however, offer a way to help prevent ethical dilemmas from occurring in the care of older cancer patients. Studies show that there is overwhelming support from both older patients and physicians for advance treatment planning through the use of living wills, durable powers of attorney for health care, and less formal means. Despite this support, few physicians and patients discuss advance directives. This paper discusses potential barriers to this dialogue and suggests specific ways to incorporate advance directive into routine cancer care of older patients. The Patient Self-Determination Act of 1990 represents additional pressure from society on the medical profession to carry out advance directive discussions.

    Gastric cancer is one of the most frequently diagnosed cancers worldwide. Although the rate of gastric cancer has declined dramatically over the past decades in most developed Western countries, it has not declined in East Asia. Currently, a radical gastrectomy is still the only curative treatment for gastric cancer. Over the last twenty years, however, surgery alone has been replaced by a multimodal perioperative approach. To achieve the maximum benefit from the perioperative treatment, a thorough evaluation of the tumor must first be performed. A complete assessment of gastric cancer is divided into two parts: staging and histology. According to the stage and histology of the cancer, perioperative chemotherapy or radiochemotherapy can be implemented, and perioperative targeted therapies such as trastuzumab may also play a role in this field. However, perioperative treatment approaches have not been widely accepted until a series of clinical trials were performed to evaluate the value of perioperative treatment. Although multimodal perioperative treatment has been widely applied in clinical practice, personalization of perioperative treatment represents the next stage in the treatment of gastric cancer. Genomic-guided treatment and efficacy prediction using molecular biomarkers in perioperative treatment are of great importance in the evolution of treatment and may become an ideal treatment method.

    OBJECTIVE. This article compares judgments about the treatment of Dukes' B2 and C colon cancer made by general surgeons to those of internists and family practitioners. Physician and practice variables were specialty, affiliation with a Community Clinical Oncology Program (CCOP) hospital, time in practice, professional centrality (level of participation in cancer information networks), solo practice, and number of colon cancer patients. DATA COLLECTION METHODS. Data are combined from national probability samples of CCOP- and non-CCOP-affiliated physicians. This study focused on 1,138 internists, family physicians, and general surgeons who participated in decision making for patients diagnosed with Dukes' B2 or C stage colon cancer. Judgments were elicited using brief vignettes. METHODS OF ANALYSIS. Judgments of adjuvant therapy are classified as (a) consistent with the National Institutes of Health Consensus Conference recommendations (experimental for Dukes' B2, accepted for Dukes' C); (b) accepted treatment for both stages; or (c) experimental for both stages. Multinomial logit analyses were used to examine the association of practice setting and physician characteristics to judgments of treatment. RESULTS. Surgeons and CCOP-affiliated physicians were more likely to endorse the NIH consensus conference position. Surgeons, younger physicians, and those in group practice were more likely to approve of chemotherapy for both cancer stages. The most common position (chemotherapy experimental) was more likely from nonsurgeons, solo practitioners, and non-CCOP physicians. CONCLUSION. Physician and practice setting characteristics, including organized structures such as the CCOP, are possible mediating structures that can facilitate dissemination of standards of treatment.

    Purpose: Creating an effective platform for multidisciplinary tumor conferences can be challenging in the rural community setting. The Duke Cancer Network created an Internet-based platform for a multidisciplinary conference to enhance the care of patients with lung cancer. This conference incorporates providers from different physical locations within a rural community and affiliated providers from a university-based cancer center 2 hours away. An electronic Web conferencing tool connects providers aurally and visually. Methods: Conferences were set up using a commercially available Web conferencing platform. The video platform provides a secure Web site coupled with a secure teleconference platform to ensure patient confidentiality. Multiple disciplines are invited to participate, including radiology, radiation oncology, thoracic surgery, pathology, and medical oncology. Participants only need telephone access and Internet connection to participate. Results: Patient histories and physicals are presented, and the Web conferencing platform allows radiologic and histologic images to be reviewed. Treatment plans for patients are discussed, allowing providers to coordinate care among the different subspecialties. Patients who need referral to the affiliated university-based cancer center for specialized services are identified. Pertinent treatment guidelines and journal articles are reviewed. On average, there are 10 participants with one to two cases presented per session. Conclusion: The use of a Web conferencing platform allows subspecialty providers throughout the community and hours away to discuss lung cancer patient cases. This platform increases convenience for providers, eliminating travel to a central location. Coordination of care for patients requiring multidisciplinary care is facilitated, shortening evaluation time before definitive treatment plan. PMID:23942505

    Traditional Chinese medicine (TCM) syndrome, also known as TCM ZHENG or TCM pattern, is an integral and essential part of TCM theory that helps to guide the design of individualized treatments. A TCM syndrome, in essence, is a characteristic profile of all clinical manifestations in one patient that can be readily identified by a TCM practitioner. In this article, the authors reviewed the presentations of TCM syndromes in seven common malignancies (liver, lung, gastric, breast, colorectal, pancreatic and esophageal cancers), the objectivity and the standardization of TCM syndrome differentiation, the evaluation of TCM syndrome modeling in cancer research, and syndrome differentiation-guided TCM treatment of cancers. A better understanding of TCM syndrome theory, as well as its potential biological basis, may contribute greatly to the clinical TCM diagnosis and the treatment of cancer.

    The PP2A signaling axis regulates multiple oncogenic drivers of castration resistant prostate cancer (CRPC). We show that targeting the endogenous PP2A regulator, SET (I2PP2A), is a viable strategy to inhibit prostate cancers that are resistant to androgen deprivation therapy. Our data is corroborated by analysis of prostate cancer patient cohorts showing significant elevation of SET transcripts. Tissue microarray analysis reveals that elevated SET expression correlates with clinical cancer grading, duration of neoadjuvant hormone therapy (NHT) and time to biochemical recurrence. Using prostate regeneration assays, we show that in vivo SET overexpression is sufficient to induce hyperplasia and prostatic intraepithelial neoplasia. Knockdown of SET induced significant reductions in tumorgenesis both in murine and human xenograft models. To further validate SET as a therapeutic target, we conducted in vitro and in vivo treatments using OP449 - a recently characterized PP2A-activating drug (PAD). OP449 elicits robust anti-cancer effects inhibiting growth in a panel of enzalutamide resistant prostate cancer cell lines. Using the Pten conditional deletion mouse model of prostate cancer, OP449 potently inhibited PI3K-Akt signaling and impeded CRPC progression. Collectively, our data supports a critical role for the SET-PP2A signaling axis in CRPC progression and hormone resistant disease.

    Cervical cancer is one of the most common cancers in women worldwide. The outcome of patients with metastatic cervical cancer is poor. We reviewed the relevant literature concerning the treatment and diagnosis of metastatic cervical cancer. There are two types of metastasis related to different treatments and survival rates: hematogenous metastasis and lymphatic metastasis. Patients with hematogenous metastasis have a higher risk of death than those with lymphatic metastasis. In terms of diagnosis, fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and PET-computed tomography are effective tools for the evaluation of distant metastasis. Concurrent chemoradiotherapy and subsequent chemotherapy are well-tolerated and efficient for lymphatic metastasis. As for lung metastasis, chemotherapy and/or surgery are valuable treatments for resistant, recurrent metastatic cervical cancer and chemoradiotherapy may be the optimal choice for stage IVB cervical cancer. Chemotherapy and bone irradiation are promising for bone metastasis. A better survival is achieved with multimodal therapy. Craniotomy or stereotactic radiosurgery is an optimal choice combined with radiotherapy for solitary brain metastases. Chemotherapy and palliative brain radiation may be considered for multiple brain metastases and other organ metastases. PMID:27171673

    Cancer vaccines are designed to expand tumor antigen-specific T cells with effector function. However, they may also inadvertently expand regulatory T cells (Treg), which could seriously hamper clinical efficacy. To address this possibility, we developed a novel assay to detect antigen-specific Treg based on down-regulation of surface CD3 following TCR engagement, and used this approach to screen for Treg specific to the NY-ESO-1 tumor antigen in melanoma patients treated with the NY-ESO-1/ISCOMATRIX™ cancer vaccine. All patients tested had Treg (CD25(bright) FoxP3(+) CD127(neg)) specific for at least one NY-ESO-1 epitope in the blood. Strikingly, comparison with pre-treatment samples revealed that many of these responses were induced or boosted by vaccination. The most frequently detected response was toward the HLA-DP4-restricted NY-ESO-1(157-170) epitope, which is also recognized by effector T cells. Notably, functional Treg specific for an HLA-DR-restricted epitope within the NY-ESO-1(115-132) peptide were also identified at high frequency in tumor tissue, suggesting that NY-ESO-1-specific Treg may suppress local anti-tumor immune responses. Together, our data provide compelling evidence for the ability of a cancer vaccine to expand tumor antigen-specific Treg in the setting of advanced cancer, a finding which should be given serious consideration in the design of future cancer vaccine clinical trials.

    Taxanes are chemotherapeutic agents with a large spectrum of antitumor activity when used as monotherapy or in combination regimens. Paclitaxel and docetaxel have poor solubility and require a complex solvent system for their commercial formulation, Cremophor EL(R) (CrEL) and Tween 80(R) respectively. Both these biological surfactants have recently been implicated as contributing not only to the hypersensitivity reactions, but also to the degree of peripheral neurotoxicity and myelosuppression, and may antagonize the cytotoxicity. Nab-paclitaxel, or nanoparticle albumin-bound paclitaxel (ABI-007; Abraxane(R)), is a novel formulation of paclitaxel that does not employ the CrEL solvent system. Nab-paclitaxel demonstrates greater efficacy and a favorable safety profile compared with standard paclitaxel in patients with advanced disease (breast cancer, non-small cell lung cancer, melanoma, ovarian cancer). Clinical studies in breast cancer have shown that nab-paclitaxel is significantly more effective than standard paclitaxel in terms of overall objective response rate (ORR) and time to progression. Nab-paclitaxel in combination with gemcitabine, capecitabine or bevacizumab has been shown to be very active in patients with advanced breast cancer. An economic analysis showed that nab-paclitaxel would be an economically reasonable alternative to docetaxel or standard paclitaxel in metastatic breast cancer. Favorable tumor ORR and manageable toxicities have been reported for nab-paclitaxel as monotherapy or in combination treatment in advanced breast cancer.

    Medical diagnosis processes vary in the degree to which they attempt to deal with different complicating aspects of diagnosis such as relative importance of symptoms, varied symptom pattern and the relation between diseases themselves. Rough set approach has two major advantages over the other methods. First, it can handle different types of data such as categorical, numerical etc. Secondly, it does not make any assumption like probability distribution function in stochastic modeling or membership grade function in fuzzy set theory. It involves pattern recognition through logical computational rules rather than approximating them through smooth mathematical functional forms. In this paper we use rough set theory as a data mining tool to derive useful patterns and rules for kidney cancer faulty diagnosis. In particular, the historical data of twenty five research hospitals and medical college is used for validation and the results show the practical viability of the proposed approach.

    The Prevent Cancer Foundation Lung Cancer Workshop XI: Tobacco-Induced Disease: Advances in Policy, Early Detection and Management was held in New York, NY on May 16 and 17, 2014. The two goals of the Workshop were to define strategies to drive innovation in precompetitive quantitative research on the use of imaging to assess new therapies for management of early lung cancer and to discuss a process to implement a national program to provide high quality computed tomography imaging for lung cancer and other tobacco-induced disease. With the central importance of computed tomography imaging for both early detection and volumetric lung cancer assessment, strategic issues around the development of imaging and ensuring its quality are critical to ensure continued progress against this most lethal cancer.

    Net survival is the survival that would be observed if the only possible underlying cause of death was the disease under study. It can be estimated with either cause-specific or relative survival data settings, if the informative censoring is properly considered. However, net survival estimators are prone to specific biases related to the data setting itself. We examined which data setting was the most robust against violation of key assumptions (erroneous cause of death and inappropriate life tables). We identified 4285 women in the Geneva Cancer Registry, diagnosed with breast, colorectal, lung cancer and melanoma between 1981 and 1991 and estimated net survival up to 20 years using cause-specific and relative survival settings. We used weights to tackle informative censoring in both settings and performed sensitivity analyses to evaluate the impact of misclassification of cause of death in the cause-specific setting or of using inappropriate life tables on net survival estimates in the relative survival setting. For all the four cancers, net survival was highest when using the cause-specific setting and the absolute difference between the two estimators increased with time since diagnosis. The sensitivity analysis showed that (i) the use of different life tables did not compromise net survival estimation in the relative survival setting, whereas (ii) a small level of misclassification for the cause of death led to a large change in the net survival estimate in the cause-specific setting. The relative survival setting was more robust to the above assumptions violations and is therefore recommended for estimation of net survival.

    A phase I study of a new cancer vaccine (KRM-10), consisting of a mixture of 10 different short peptides, was conducted for patients with advanced gastrointestinal cancers. Primary or secondary endpoints included the dose-limiting toxicity (DLT), or safety and immune responses, respectively. Peptide-specific cytotoxic T lymphocytes (CTL) and immunoglobulin G (IgG), together with soluble inflammatory factors, were measured before and after vaccination. Twenty-one patients were vaccinated with KRM-10 at dose levels of 10 (n = 6), 20 (n = 8) or 30 mg (n = 7) of peptides every week for 6 weeks. No DLT were observed in the dose range evaluated. Common treatment-related adverse events were a grade 1 injection site reaction in 15 patients, and fever in three patients (grade 1 in two patients and grade 2 in one patient). CTL activity to at least one peptide at the time of the third and sixth vaccination increased in 2 and 3 of 6 (10 mg), 2 of 8 and 4 of 6 (20 mg), or 2 and 1 of 6 (30 mg) patients, respectively. IgG levels, at the third and sixth vaccination, were also increased in 1 and 1 of 6 (10 mg), 2 of 8 and 4 of 6 (20 mg), or 1 and 3 of 6 (30 mg) patients, respectively. The KRM-10 vaccine consisting of 20 mg of peptides was determined as the optimal dose for a coming phase II trial because of its safety, and also for demonstrating the most potent activity for augmenting the immune response of the three doses tested. This trial was registered at the UMIN Clinical Trials Registry as UMIN000008820.

    Background The prognostic and predictive significance of the high-level microsatellite instability (MSI-H) phenotype in various malignancies is unclear. We describe the characteristics, clinical course, and outcomes of patients with MSI-H malignancies treated in a real-life hospital setting. Patients and methods A retrospective analysis of MSI-H cancer patient files was conducted. We analyzed the genetic data, clinical characteristics, and oncological treatments, including chemotherapy and surgical interventions. Results Clinical data of 73 MSI-H cancer patients were available. Mean age at diagnosis of first malignancy was 52.3 years. Eight patients (11%) had more than four malignancies each. Most patients (76%) had colorectal cancer (CRC). Seventeen patients (23%) had only extracolonic malignancies. Eighteen women (36%) had gynecological malignancy. Nine women (18%) had breast cancer. Mean follow-up was 8.5 years. Five-year overall survival and disease-free survival of all MSI-H cancer patients from first malignancy were 86% and 74.6%, respectively. Five-year overall survival rates of stage 2, 3, and 4 MSI-H CRC patients were 89.5%, 58.4%, and 22.9%, respectively. Conclusion Although the overall prognosis of MSI-H cancer patients is favorable, this advantage may not be maintained in advanced MSI-H CRC patients.

    Tumor vascular patterns of advanced breast cancers are complex and heterogeneous. Two typical light absorption patterns of periphery enhancement and posterior shadowing have been observed when imaging these advanced cancers using optical tomography guided by ultrasound. We perform a series simulation and phantom experiments to systemically evaluate the effects of target parameters, target locations, and target optical properties on imaging periphery enhancement absorption distribution using reflection geometry. Large tumors are modeled as concentric semiellipsoidal targets of different outer shell and inner core optical properties. We show that larger targets of more than 3 to 4 cm diameter with outer shell thicknesses less than 1 cm can be resolved at a depth less than 3 cm. A clinical example is given to show the complex vasculature distributions seen from an advanced cancer. PMID:21198181

    To complement the existing treatment guidelines for all tumour types, ESMO organises consensus conferences to focus on specific issues in each type of tumour. The 2nd ESMO Consensus Conference on Lung Cancer was held on 11-12 May 2013 in Lugano. A total of 35 experts met to address several questions on non-small-cell lung cancer (NSCLC) in each of four areas: pathology and molecular biomarkers, first-line/second and further lines of treatment in advanced disease, early-stage disease and locally advanced disease. For each question, recommendations were made including reference to the grade of recommendation and level of evidence. This consensus paper focuses on locally advanced disease.

    The natural history of HR+ breast cancer tends to be different from hormone receptor-negative disease in terms of time to recurrence, site of recurrence and overall aggressiveness of the disease. The developmental strategies of hormone therapy for the treatment of breast cancer have led to the classes of selective estrogen receptor modulators, selective estrogen receptor downregulators, and aromatase inhibitors. These therapeutic options have improved breast cancer outcomes in the metastatic setting, thereby delaying the need for chemotherapy. However, a subset of hormone receptor-positive breast cancers do not benefit from endocrine therapy (intrinsic resistance), and all HR+ metastatic breast cancers ultimately develop resistance to hormonal therapies (acquired resistance). Considering the multiple pathways involved in the HR network, targeting other components of pathologically activated intracellular signaling in breast cancer may prove to be a new direction in clinical research. This review focuses on current and emerging treatments for HR+ metastatic breast cancer.

    Robotic technology, which has recently been introduced to the field of surgery, is expected to be useful, particularly in treating rectal cancer where precise manipulation is necessary in the confined pelvic cavity. Robotic surgery overcomes the technical drawbacks inherent to laparoscopic surgery for rectal cancer through the use of multi-articulated flexible tools, three-dimensional stable camera platforms, tremor filtering and motion scaling functions, and greater ergonomic and intuitive device manipulation. Assessments of the feasibility and safety of robotic surgery for rectal cancer have reported similar operation times, blood loss during surgery, rates of postoperative morbidity, and circumferential resection margin involvement when compared with laparoscopic surgery. Furthermore, rates of conversion to open surgery are reportedly lower with increased urinary and male sexual functions in the early postoperative period compared with laparoscopic surgery, demonstrating the technical advantages of robotic surgery for rectal cancer. However, long-term outcomes and the cost-effectiveness of robotic surgery for rectal cancer have not been fully evaluated yet; therefore, large-scale clinical studies are required to evaluate the efficacy of this new technology.

    Colorectal cancer is essentially an environmental and genetic disease featured by uncontrolled cell growth and the capability to invade other parts of the body by forming metastases, which inconvertibly cause great damage to tissues and organs. It has become one of the leading causes of cancer-related mortality in the developed countries such as United States, and approximately 1.2 million new cases are yearly diagnosed worldwide, with the death rate of more than 600,000 annually and incidence rates are increasing in most developing countries. Apart from the generally accepted theory that pathogenesis of colorectal cancer consists of genetic mutation of a certain target cell and diversifications in tumor microenvironment, the colorectal cancer stem cells (CCSCs) theory makes a different explanation, stating that among millions of colon cancer cells there is a specific and scanty cellular population which possess the capability of self-renewal, differentiation and strong oncogenicity, and is tightly responsible for drug resistance and tumor metastasis. Based on these characteristics, CCSCs are becoming a novel target cells both in the clinical and the basic studies, especially the study of CCSCs vaccines due to induced efficient immune response against CCSCs. This review provides an overview of CCSCs and preparation technics and targeting factors related to CCSCs vaccines in detail.

  2. Trastuzumab: a novel standard option for patients with HER-2-positive advanced gastric or gastro-oesophageal junction cancer

    PubMed Central

    Cunningham, David

    2012-01-01

    The human epidermal receptor-2 (HER-2) is amplified in up to 25% of patients with gastroesophageal adenocarcinomas. Although the presence of this amplification does not appear to confer a poor prognosis, it provides a valuable novel therapeutic target for this group of patients. Trastuzumab is a fully humanized monoclonal antibody directed at HER-2 which binds the external domain of the receptor and exerts its action via a combination of antibody-dependent cytotoxicity, reduced shedding of the extracellular domain, inhibition of dimerization and possibly receptor downregulation. The ToGA trial was an international multicentre randomized phase III study which evaluated the addition of trastuzumab to a cisplatin plus fluoropyrimidine chemotherapy doublet in 594 patients with HER-2-positive advanced gastric or oesophagogastric junction adenocarcinoma. The combination of the antibody with chemotherapy significantly improved response rate, median progression-free survival and median overall survival without additional toxicity or adversely affecting quality of life. Accordingly, trastuzumab plus chemotherapy is now a standard first-line treatment option for patients with advanced HER-2-positive gastroesophageal cancer. Unfortunately, many patients with HER-2-positive cancer exhibit primary resistance to trastuzumab and the remainder will acquire resistance to the antibody; therefore, urgent investigation into novel agents which may circumvent resistance mechanisms is warranted. Small molecule inhibitors of HER-2, which commonly also target other members of the HER family of receptors, such as EGFR and HER-3, are currently undergoing evaluation in gastroesophageal cancer as first-line alternatives to trastuzumab and second-line salvage treatments for trastuzumab-resistant disease. Extrapolating the successful use of trastuzumab in the advanced disease setting, clinical trials are underway to assess the role of this antibody in the perioperative and adjuvant settings

    The last decade has witnessed remarkable technological advances in mass spectrometry-based proteomics. The development of proteomics techniques has enabled the reliable analysis of complex proteomes, leading to the identification and quantification of thousands of proteins in gastric cancer cells, tissues, and sera. This quantitative information has been used to profile the anomalies in gastric cancer and provide insights into the pathogenic mechanism of the disease. In this review, we mainly focus on the advances in mass spectrometry and quantitative proteomics that were achieved in the last five years and how these up-and-coming technologies are employed to track biochemical changes in gastric cancer cells. We conclude by presenting a perspective on quantitative proteomics and its future applications in the clinic and translational gastric cancer research. PMID:27729735

    Surgeons occasionally encounter a patient with a gastric cancer invading an adjacent organ, such as the pancreas, liver, or transverse colon. Although there is no established guideline for treatment of invasive gastric cancer, combined resection with radical gastrectomy is conventionally performed for curative purposes. We recently treated a patient with a large gastric cancer invading the abdominal wall, which was initially diagnosed as a simple abdominal wall abscess. Computed tomography showed that an abscess had formed adjacent to the greater curvature of the stomach. During surgery, we made an incision on the abdominal wall to drain the abscess, and performed curative total gastrectomy with partial excision of the involved abdominal wall. The patient received intensive treatment and wound management postoperatively with no surgery-related adverse events. However, the patient could not receive adjuvant chemotherapy and expired on the 82nd postoperative day. PMID:26468420

    2013-01-01

    Signal transducer and activator of transcription 3 (STAT3) is a latent cytoplasmic transcription factor, originally discovered as a transducer of signal from cell surface receptors to the nucleus. It is activated by tyrosine phosphorylation at position 705 leading to its dimerization, nuclear translocation, DNA binding, and activation of gene transcription. Under normal physiological conditions, STAT3 activation is tightly regulated. However, compelling evidence suggests that STAT3 is constitutively activated in many cancers and plays a pivotal role in tumor growth and metastasis. It regulates cellular proliferation, invasion, migration, and angiogenesis that are critical for cancer metastasis. In this paper, we first describe the mechanism of STAT3 regulation followed by how STAT3 is involved in cancer metastasis, then we summarize the various small molecule inhibitors that inhibit STAT3 signaling.

    Background: The definition of health for people with cancer is not focused solely on the physiology of illness and the length of life remaining, but is also concerned with improving the well-being and the quality of the life (QOL) remaining to be lived. This study aimed to identify the constructs most associated with QOL in people with advanced cancer. Methods: Two hundred three persons with recent diagnoses of different advanced cancers were evaluated with 65 variables representing individual and environmental factors, biological factors, symptoms, function, general health perceptions and overall QOL at diagnosis. Three independent stepwise multiple linear regressions identified the most important contributors to overall QOL. R2 ranking and effect sizes were estimated and averaged by construct. Results: The most important contributor of overall QOL for people recently diagnosed with advanced cancer was social support. It was followed by general health perceptions, energy, social function, psychological function and physical function. Conclusions: We used effect sizes to summarise multiple multivariate linear regressions for a more manageable and clinically interpretable picture. The findings emphasise the importance of incorporating the assessment and treatment of relevant symptoms, functions and social support in people recently diagnosed with advanced cancer as part of their clinical care.

    Objective: The objective of this study was to describe the experiences of Zambian nurses caring for women with advanced breast cancer. Methods: We used a qualitative descriptive design and purposive sampling. Seventeen in-depth interviews were conducted with registered nurses practicing in the Cancer Diseases Hospital and the University Teaching Hospital, Lusaka, Zambia, and analyzed using thematic analyses. Results: Two themes emerged from the data - caring for women with advanced breast cancer is challenging and the good outweighs the bad. The majority of the participants agreed that caring for women with advanced breast cancer and witnessing their suffering were challenging. Not having formal education and training in oncology nursing was disempowering, and one of the various frustrations participants experienced. The work environment, learning opportunities, positive patient outcomes, and the opportunity to establish good nurse–patient experiences were positive experiences. Conclusions: Although negative experiences seemed to be overwhelming, participants reported some meaningful experiences while caring for women with advanced breast cancer. The lack of formal oncology nursing education and training was a major factor contributing to their negative experiences and perceived as the key to rendering the quality of care patients deserved. Ways to fulfill the educational needs of nurses should be explored and instituted, and nurses should be remunerated according to their levels of practice. PMID:28217726

    Background. Despite the great achievements in the treatment of advanced-stage ovarian cancer, it is still a severe condition with an unfavorable 5-year survival rate. Statins have been suggested to reduce the risk of several cancers beyond their cholesterol-lowing effects. However, the prognostic significance of statins in patients with advanced-stage ovarian cancer remains controversial. Methods. A retrospective study was performed to evaluate the association between statin intake and overall survival (OS) among patients with advanced-stage ovarian cancer. Patients who underwent cytoreductive surgery followed by courses of intravenous chemotherapy were matched through a propensity score analysis. Results. A total of 60 propensity-matched patients were included. Women in statin group showed a similar OS than the nonstatin counterparts (P = 0.966), whereas residual tumor was significantly associated with better OS (P = 0.013) and was an independent factor that associated with OS (P = 0.002, hazard ratio = 5.460, and 95% confidence interval: 1.894 to 15.742) in multivariable analysis. Conclusions. Our results suggested that statin usage was not associated with improved OS in patients with advanced-stage ovarian cancer undergoing surgery and chemotherapy. Considering the retrospective nature and the relative small sample size of the study, further prospective studies and random control trials are needed. PMID:27975064

    Metabolic demand and altered supply of essential nutrients is poorly characterised in patients with advanced cancer. A possible imbalance or deficiency of essential fatty acids is suggested by reported beneficial effects of fish oil supplementation. To assess fatty acid status (composition of plasma and neutrophil phospholipids) in advanced cancer patients before and after 14 days of supplementation (12+/-1 g day(-1)) with fish (eicosapentaenoic acid, and docosahexaenoic acid) or placebo (olive) oil. Blood was drawn from cancer patients experiencing weight loss of >5% body weight (n=23). Fatty acid composition of plasma phospholipids and the major phospholipid classes of isolated neutrophils were determined using gas liquid chromatography. At baseline, patients with advanced cancer exhibited low levels (<30% of normal values) of plasma phospholipids and constituent fatty acids and elevated 20 : 4 n-6 content in neutrophil phospholipids. High n-6/n-3 fatty acid ratios in neutrophil and plasma phospholipids were inversely related to body mass index. Fish oil supplementation raised eicosapentaenoic acid and docosahexaenoic acid content in plasma but not neutrophil phospholipids. 20 : 4 n-6 content was reduced in neutrophil PI following supplementation with fish oil. Change in body weight during the supplementation period related directly to increases in eicosapentaenoic acid in plasma. Advanced cancer patients have alterations in lipid metabolism potentially due to nutritional status and/or chemotherapy. Potential obstacles in fatty acid utilisation must be addressed in future trials aiming to improve outcomes using nutritional intervention with fish oils.

    2010-01-01

    Although the introduction of novel therapies and drug combinations has improved the prognosis of metastatic breast cancer, the disease remains incurable. Increased knowledge of the biology and the molecular alterations in breast cancer has facilitated the design of targeted therapies. These agents include receptor and nonreceptor tyrosine kinase inhibitors (epidermal growth factor receptor family), intracellular signaling pathways (phosphatidylinositol-3-kinase, AKT, mammalian target of rapamycin) angiogenesis inhibitors and agents that interfere with DNA repair (poly(ADP-ribose) polymerase inhibitors). In the present review, we present the most promising studies of these new targeted therapies and novel combinations of targeted therapies with cytotoxic agents. PMID:21050422

    Cancer cells uptake glucose at a higher rate and produce lactic acid rather than metabolizing pyruvate through the tricarboxylic acid cycle. This adaptive metabolic shift is termed the Warburg effect. Recently progress had been made regarding the mechanistic understanding of glucose metabolism and associated diagnostic and therapeutic methods, which have been investigated in colorectal cancer. The majority of novel mechanisms involve important glucose metabolism associated genes and miRNA regulation. The present review discusses the contribution of these research results to facilitate with the development of novel diagnosis and anticancer treatment options. PMID:27602209

    Subramaniam, Prasad

    Nanotechnology offers tremendous potential for use in biomedical applications, including cancer and stem cell imaging, disease diagnosis and drug delivery. The development of nanosystems has aided in understanding the molecular mechanisms of many diseases and permitted the controlled nanoscale manipulation of biological phenomena. In recent years, many studies have focused on the use of several kinds of nanomaterials for cancer and stem cell imaging and also for the delivery of anticancer therapeutics to tumor cells. However, the proper diagnosis and treatment of aggressive tumors such as brain and breast cancer requires highly sensitive diagnostic agents, in addition to the ability to deliver multiple therapeutics using a single platform to the target cells. Addressing these challenges, novel multifunctional nanomaterial-based platforms that incorporate multiple therapeutic and diagnostic agents, with superior molecular imaging and targeting capabilities, has been presented in this work. The initial part of this work presents the development of novel nanomaterials with superior optical properties for efficiently delivering soluble cues such as small interfering RNA (siRNA) into brain cancer cells with minimal toxicity. Specifically, this section details the development of non-toxic quantums dots for the imaging and delivery of siRNA into brain cancer and mesenchymal stem cells, with the hope of using these quantum dots as multiplexed imaging and delivery vehicles. The use of these quantum dots could overcome the toxicity issues associated with the use of conventional quantum dots, enabled the imaging of brain cancer and stem cells with high efficiency and allowed for the delivery of siRNA to knockdown the target oncogene in brain cancer cells. The latter part of this thesis details the development of nanomaterial-based drug delivery platforms for the co-delivery of multiple anticancer drugs to brain tumor cells. In particular, this part of the thesis focuses on

    2017-02-01

    Corticosteroids have been widely used for decades in cancer therapy, predominantly due to their anti-inflammatory activity. In the treatment of metastatic castration-resistant prostate cancer (mCRPC), corticosteroids play an important role both in the management of tumor-related symptoms, especially bone metastasis-related pain, and as concomitant treatment to counteract side effects associated with approved active prostatic anticancer agents such as docetaxel, cabazitaxel, and abiraterone acetate. In association with abiraterone acetate, low-dose corticosteroids (prednisone or prednisolone) reduce the mineralocorticoid side effects of abiraterone. In addition, corticosteroids may exert direct antitumoral activities, resulting in PSA decline.

    Advanced cancer patients are polysymptomatic and often receive multiple medications for symptom relief. Common symptoms include anorexia, weight loss, delirium and depression. Olanzapine and mirtazapine may have several advantages over older agents despite increased acquisition costs. Both medications can treat several symptoms with a low risk for drug-drug interactions and with only once- or twice-daily dosing. Drug side effects are low, compared with more conventionally used agents. The pharmacokinetics and pharmacodynamics of both agents are unique and explain many of the benefits. More research and clinical experience will be necessary to define their role in the palliation of advanced cancer.

    The field of therapeutic stem cell and oncolytic virotherapy for cancer treatment has rapidly expanded over the past decade. Oncolytic viruses constitute a promising new class of anticancer agent because of their ability to selectively infect and destroy tumor cells. Engineering of viruses to express anticancer genes and specific cancer targeting molecules has led to the use of these systems as a novel platform of metastatic cancer therapy. In addition, stem cells have a cancer specific migratory capacity, which is available for metastatic cancer targeting. Prodrug activating enzyme or anticancer cytokine expressing stem cells successfully inhibited the proliferation of cancer cells. Preclinical models have clearly demonstrated anticancer activity of these two platforms against a number of different cancer types and metastatic cancer. Several systems using therapeutic stem cells or oncolytic virus have entered clinical trials, and promising results have led to late stage clinical development. Consequently, metastatic cancer therapies using stem cells and oncolytic viruses are extremely promising. The following review will focus on the metastatic cancer targeting mechanism of therapeutic stem cells and oncolytic viruses, and potential challenges ahead for advancing the field.

    Introduction Gene-set analysis (GSA) is an approach using the results of single-marker genome-wide association studies when investigating pathways as a whole with respect to the genetic basis of a disease. Methods We performed a meta-analysis of seven GSAs for lung cancer, applying the method META-GSA. Overall, the information taken from 11,365 cases and 22,505 controls from within the TRICL/ILCCO consortia was used to investigate a total of 234 pathways from the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Results META-GSA reveals the systemic lupus erythematosus KEGG pathway hsa05322, driven by the gene region 6p21-22, as also implicated in lung cancer (p = 0.0306). This gene region is known to be associated with squamous cell lung carcinoma. The most important genes driving the significance of this pathway belong to the genomic areas HIST1-H4L, -1BN, -2BN, -H2AK, -H4K and C2/C4A/C4B. Within these areas, the markers most significantly associated with LC are rs13194781 (located within HIST12BN) and rs1270942 (located between C2 and C4A). Conclusions We have discovered a pathway currently marked as specific to systemic lupus erythematosus as being significantly implicated in lung cancer. The gene region 6p21-22 in this pathway appears to be more extensively associated with lung cancer than previously assumed. Given wide-stretched linkage disequilibrium to the area APOM/BAG6/MSH5, there is currently simply not enough information or evidence to conclude whether the potential pleiotropy of lung cancer and systemic lupus erythematosus is spurious, biological, or mediated. Further research into this pathway and gene region will be necessary. PMID:28273134

    Objective: The conformal nature of dose distribution produced by volumetric modulated arc radiotherapy (VMAT) increases the risk of geographic miss. Data regarding patterns of failure after VMAT in oral cavity cancers in resource-constrained settings are scarce. The aim of the present study was to ascertain the patterns of failure in patients receiving adjuvant VMAT intensity-modulated radiotherapy (IMRT) for oral cavity cancer in Malabar Cancer Center, Kerala, India. Methods: Data of patients with oral cavity cancer receiving adjuvant VMAT IMRT between April 2012 and March 2014 were collected. Recurrent volumes were delineated on the treatment planning images and classified as defined by Dawson et al (Dawson LA, Anzai Y, Marsh L, Martel MK, Paulino A, Ship JA, et al. Patterns of local-regional recurrence following parotid-sparing conformal and segmental intensity-modulated radiotherapy for head and neck cancer. Int J Radiat Oncol Biol Phys 2000; 46: 1117–26). Results: 75 patients with a median follow-up of 24 months were analysed. 41 (55%) patients had oral tongue cancers and 52 (69%) of the patients had Stage IVA cancers. The 2-year locoregional recurrence-free survival, disease-free survival and overall survival were 88.9%, 82.1% and 80.5%, respectively. With a median time to failure of 6.5 months, five infield and three outfield failures were identified. Conclusion: A relatively low rate of outfield failure and lack of marginal failure attests to the efficacy of VMAT in such patients. Modifications to our existing target delineation policy have been proposed. Advances in knowledge: The use of standardized target delineation methods allows safe use of VMAT IMRT even in resource-constrained settings. PMID:25645107

    SUMMARY Background Current guidelines do not recommend screening for nonalcoholic fatty liver disease (NAFLD) or advanced fibrosis. Patients with type 2 diabetes mellitus (T2DM) are known to be at increased risk for NAFLD and advanced fibrosis. Aim We aimed to assess the feasibility in diabetics in a primary care setting of screening for NAFLD and advanced fibrosis by using non-invasive magnetic resonance imaging (MRI) to estimate the hepatic proton density fat fraction (MRI-PDFF) and magnetic resonance elastography (MRE) to estimate hepatic stiffness. Methods We performed a cross-sectional analysis of a prospective study that included 100 (53% men) consecutively enrolled diabetics who did not have any other etiology of liver disease. All patients underwent a standardized research visit, laboratory tests, MRI-PDFF, and MRE. Results Mean (± SD) age and BMI was 59.7 (±11.2) years and 30.8 (±6.5) kg/m2, respectively. The prevalence of NAFLD (defined as MRI-PDFF ≥ 5%) and advanced fibrosis (defined as MRE ≥ 3.6 kPa) was 65% and 7.1%, respectively. One patient with advanced fibrosis had definite hepatocellular carcinoma. When compared to those without NAFLD, patients with NAFLD were younger (p=0.028) and had higher mean BMI (p=0.0008), waist circumference (p<0.0001) and prevalence of metabolic syndrome (84.6% vs. 40.0%, p<0.0001). Only 26% of those with NAFLD had elevated ALT. Conclusions This proof-of-concept study demonstrates that T2DM has significant rates of both NAFLD and advanced fibrosis. Concomitant screening for NAFLD and advanced fibrosis by using MRI-PDFF and MRE in T2DM is feasible and may be considered after validation in a larger cohort. PMID:26369383

    Neo-vascularization is a vital process for tumor growth and development which involves the interaction between tumor cells and stromal endothelial cells through several growth factors and membranous receptors which ultimately activate pro-angiogenic intracellular signaling pathways. Inhibition of angiogenesis has become a standard treatment option for several tumor types including colorectal cancer, glioblastoma and ovarian cancer. In gastric cancer, the therapeutic role of anti-angiogenic agents is more controversial. Bevacizumab and ramucirumab, two monoclonal antibodies, which target vascular endothelial growth factor-A and vascular endothelial growth factor receptor-2, respectively, have been demonstrated antitumor activity in patients with tumors of the stomach or esophagogastric junction. However, especially for bevacizumab, this antitumor activity has not consistently translated into a survival advantage over standard treatment in randomized trials. In this article, we provide an overview of the role of angiogenesis in gastric cancer and discuss the results of clinical trials that investigated safety and effectiveness of antiangiogenic therapies in this disease. A review of the literature has been done using PubMed, ClinicalTrials.gov website and the ASCO Annual Meeting Library. PMID:25538401

    Letrozole (Femara; Novartis Pharmaceuticals Corp., East Hanover, NJ) is a nonsteroidal inhibitor of aromatase enzyme complex. It inhibits the peripheral conversion of circulating androgens to estrogens. In postmenopausal women, letrozole decreases plasma concentrations of estradiol, estrone, and estrone sulfate by 75-95% from baseline with maximal suppression achieved within 2-3 days of treatment initiation. Suppression is dose related, with doses of >or=0.5 mg giving estrone and estrone sulfate values that were often below assay detection limits. At clinically used dosage, letrozole does not impair adrenal synthesis of glucocorticoids or aldosterone. In 1998, letrozole was approved by the United States Food and Drug Administration (FDA) for the treatment of advanced breast cancer in postmenopausal women, with hormone receptor positive or unknown breast cancer, who had failed one prior antiestrogen treatment (i.e., for "second-line" treatment). Approval was based on two randomized trials comparing tumor RRs of patients receiving 0.5 mg of letrozole, 2.5 mg of letrozole, and either megestrol acetate (MA) or aminoglutethimide. In the megestrol trial, 2.5 mg/day letrozole was superior to 0.5 mg of letrozole and MA (RRs 24, 13, and 16%, respectively), whereas in the aminoglutethimide trial, there was no significant difference in 2.5 mg of letrozole and 0.5 mg of letrozole RRs (20 and 17%). There was a trend toward RR superiority of 2.5 mg of letrozole over aminoglutethimide (P = 0.06). Letrozole (2.5 mg) was the dose chosen for comparison with tamoxifen in the first-line setting. In July 2000, a marketing application for first-line letrozole treatment of postmenopausal women with hormone receptor positive or hormone receptor unknown locally advanced or metastatic breast cancer was submitted to the FDA. A single double-blind, double dummy, randomized, and multicenter trial compared 2.5 mg of letrozole to 20 mg of tamoxifen (456 patients/arm). Letrozole was superior to

    ABSTRACT The use of nanocarriers as drug delivery systems for therapeutic or imaging agents can improve the pharmacological properties of commonly used compounds in cancer diagnosis and treatment. Advances in the surface engineering of nanoparticles to accommodate targeting ligands turned nanocarriers attractive candidates for future work involving targeted drug delivery. Although not targeted, several nanocarriers have been approved for clinical use and they are currently used to treat and/or diagnosis various types of cancers. Furthermore, there are several formulations, which are now in various stages of clinical trials. This review examined some approved formulations and discussed the advantages of using nanocarriers in cancer therapy. PMID:27074238

    Diabetic patients have increased levels of advanced glycation end products (AGEs) and the role of AGEs in regulating cancer cell proliferation is unclear. Here, we found that treating colorectal and liver cancer cells with AGEs promoted cell proliferation. AGEs stimulated both the expression and activation of a key transcription factor called carbohydrate responsive element binding protein (ChREBP) which had been shown to promote glycolytic and anabolic activity as well as proliferation of colorectal and liver cancer cells. Using siRNAs or the antagonistic antibody for the receptor for advanced glycation end-products (RAGE) blocked AGEs-induced ChREBP expression or cell proliferation in cancer cells. Suppressing ChREBP expression severely impaired AGEs-induced cancer cell proliferation. Taken together, these results demonstrate that AGEs-RAGE signaling enhances cancer cell proliferation in which AGEs-mediated ChREBP induction plays an important role. These findings may provide new explanation for increased cancer progression in diabetic patients.

    Lung cancer patients experience loss of physical capacity, dyspnea, pain, reduced energy and psychological distress. The aim of this study was to explore feasibility, health benefits and barriers of exercise in former sedentary patients with advanced stage lung cancer, non-small cell lung cancer (NSCLC) (III-IV) and small cell lung cancer (SCLC) (ED), undergoing chemotherapy. The intervention consisted of a hospital-based, supervised, group exercise and relaxation program comprising resistance-, cardiovascular- and relaxation training 4 h weekly, 6 weeks, and a concurrent unsupervised home-based exercise program. An explorative study using individual semi-structured interviews (n=15) and one focus group interview (n=8) was conducted among the participants. Throughout the intervention the patients experienced increased muscle strength, improvement in wellbeing, breathlessness and energy. The group exercise and relaxation intervention showed an adherence rate of 76%, whereas the patients failed to comply with the home-based exercise. The hospital-based intervention initiated at time of diagnosis encouraged former sedentary lung cancer patients to participation and was undertaken safely by cancer patients with advanced stages of disease, during treatment. The patients experienced physical, functional and emotional benefits. This study confirmed that supervised training in peer-groups was beneficial, even in a cancer population with full-blown symptom burden and poor prognosis.

    Lung cancer is one of the most common types of malignancies worldwide. The majority of patients are diagnosed with an incurable advanced/metastatic stage disease. Palliative treatment approaches improve the survival and the quality of life of these patients. Lung cancer is subdivided according to histology and molecular biology. The most important classification separates small cell from non-small cell lung cancer. In the subgroup of non-small cell lung cancer novel treatment approaches coming along with an improved prognosis have been established during the last decade. The current manuscript provides an overview on current treatment options for metastatic lung cancer. Furthermore, an outlook on promising future treatment options is provided.

    Patients with cancer often experience insomnia. Nightmares are also a strong factor that interferes with the maintenance of comfortable and satisfying sleep. However, the prevalence and standard treatment of nightmares in patients with cancer have not been established yet. We aimed to treat insomnia and nightmares with trazodone. From 2008 to 2011, trazodone was prescribed to 30 patients with cancer who reported experiencing insomnia with or without nightmares to the palliative care team in Osaka University Hospital. Effective treatment was seen in 15 patients (50%). Four patients with cancer reported having severe nightmares and 2 patients had beneficial effects, with frightening dreams transformed into acceptable ones. Trazodone may be an effective drug for the treatment of insomnia and nightmares in patients with advanced cancer.

    Dendritic cell (DC)-based vaccine strategies aimed at targeting cancer stem-like cells (CSC) may be most efficacious if deployed in the adjuvant setting. In this study, we offer preclinical evidence this is the case for a CSC-DC vaccine as tested in murine models of SCC7 squamous cell cancer and D5 melanoma. Vaccination of mice with an ALDHhigh SCC7 CSC-DC vaccine after surgical excision of established SCC7 tumors reduced local tumor relapse and prolonged host survival. This effect was augmented significantly by simultaneous administration of anti-PD-L1, an immune checkpoint inhibitor. In the minimal disease setting of D5 melanoma, treatment of mice with ALDHhigh CSC-DC vaccination inhibited primary tumor growth, reduced spontaneous lung metastases and increased host survival. In this setting, CCR10 and its ligands were downregulated on ALDHhigh D5 CSCs and in lung tissues respectively after vaccination with ALDHhigh D5 CSC-DC. RNAi-mediated attenuation of CCR10 blocked tumor cell migration in vitro and metastasis in vivo. T cells harvested from mice vaccinated with ALDHhigh D5 CSC-DC selectively killed ALDHhigh D5 CSCs, with additional evidence of humoral immunological engagement and a reduction in ALDHhigh cells in residual tumors. Overall, our results offered a preclinical proof of concept for the use of ALDHhigh CSC-DC vaccines in the adjuvant setting to more effectively limit local tumor recurrence and spontaneous pulmonary metastasis, as compared with traditional DC vaccines, with increased host survival further accentuated by simultaneous PD-L1 blockade.

    We undertook a phase I dose-escalation study of verteporfin photodynamic therapy (PDT) in 15 patients with locally advanced pancreatic cancer. Needle placement and laser delivery were technically successful in all patients. Thirteen patients were treated with a single laser fibre. Three treatments were carried out each at 5, 10 and 20 J/cm2; and 5 treatments (4 patients) at 40 J/cm2. A further 2 patients were treated with 2 or 3 laser fibres at 40 J/cm2. Tumour necrosis was measured on CT (computed tomography) by two radiologists 5 days after treatment. There was a clear dosedependent increase in necrosis with a median area of 20 x 16 mm (range 18 x 16 to 35 x 30 mm) at 40 J/cm2. In the 2 patients treated with multiple fibres, necrosis was 40 x 36 mm and 30 x 28 mm, respectively. There were no early complications in patients treated with a single fibre. Both patients treated with multiple fibres had evidence on CT of inflammatory change occurring anterior to the pancreas but without clinical deterioration. These results suggest that single fibre verteporfin PDT is safe in a clinical setting up to 40J/cm2 and produces a dose-dependent area of pancreatic necrosis.

    Most patients with non-small cell lung cancer (NSCLC) present with advanced disease requiring systemic chemotherapy. Treatment with the antiangiogenic agent bevacizumab in combination with standard platinum-based doublet chemotherapy has been shown to improve outcomes in patients with advanced NSCLC. Several multitargeted antiangiogenic tyrosine kinase inhibitors (e.g., sorafenib, sunitinib, cediranib, vandetanib, BIBF 1120, pazopanib, and axitinib) are also being evaluated in combination with standard chemotherapy. Here we review current clinical data with combination therapy involving antiangiogenic agents and cytotoxic chemotherapy in patients with advanced NSCLC. PMID:21469981

    Natural products are often used in drug development due to their ability to form unique and diverse chemical structures. Coumestans are polycyclic aromatic plant secondary metabolites containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. These natural compounds are known for large number of biological activities. Many of their biological effects can be attributed to their action as phytoestrogens and polyphenols. In the last decade, anticancer effects of these compounds have been described in vitro but there is only limited number of studies based on models in vivo. More information concerning their in vivo bioavailability, stability, metabolism, toxicity, estrogenicity, cellular targets and drug interactions is therefore needed to proceed further to clinical studies. This review focuses on coumestans exhibiting anticancer properties and summarizes mechanisms of their toxicity to cancer cells. Moreover, the possible role of coumestans in cancer prevention is discussed.

    For Monte Carlo simulations to be used as an alternative solution to perform scatter correction, accurate modelling of the scanner as well as speed is paramount. General-purpose Monte Carlo packages (Geant4, EGS, MCNP) allow a detailed description of the scanner but are not efficient at simulating voxel-based geometries (patient images). On the other hand, dedicated codes (SimSET, PETSIM) will perform well for voxel-based objects but will be poor in their capacity of simulating complex geometries such as a PET scanner. The approach adopted in this work was to couple a dedicated code (SimSET) with a general-purpose package (Geant4) to have the efficiency of the former and the capabilities of the latter. The combined SimSET+Geant4 code (SimG4) was assessed on the GE Advance PET scanner and compared to the use of SimSET only. A better description of the resolution and sensitivity of the scanner and of the scatter fraction was obtained with SimG4. The accuracy of scatter correction performed with SimG4 and SimSET was also assessed from data acquired with the 20 cm NEMA phantom. SimG4 was found to outperform SimSET and to give slightly better results than the GE scatter correction methods installed on the Advance scanner (curve fitting and scatter modelling for the 300-650 keV and 375-650 keV energy windows, respectively). In the presence of a hot source close to the edge of the field of view (as found in oxygen scans), the GE curve-fitting method was found to fail whereas SimG4 maintained its performance.

    Given the success of targeted agents in specific populations it is expected that some degree of molecular biomarker testing will become standard of care for many, if not all, cancers. To facilitate this, cancer centers worldwide are experimenting with targeted “panel” sequencing of selected mutations. Recent advances in genomic technology enable the generation of genome-scale data sets for individual patients. Recognizing the risk, inherent in panel sequencing, of failing to detect meaningful somatic alterations, we sought to establish processes to integrate data from whole-genome analysis (WGA) into routine cancer care. Between June 2012 and August 2014, 100 adult patients with incurable cancers consented to participate in the Personalized OncoGenomics (POG) study. Fresh tumor and blood samples were obtained and used for whole-genome and RNA sequencing. Computational approaches were used to identify candidate driver mutations, genes, and pathways. Diagnostic and drug information were then sought based on these candidate “drivers.” Reports were generated and discussed weekly in a multidisciplinary team setting. Other multidisciplinary working groups were assembled to establish guidelines on the interpretation, communication, and integration of individual genomic findings into patient care. Of 78 patients for whom WGA was possible, results were considered actionable in 55 cases. In 23 of these 55 cases, the patients received treatments motivated by WGA. Our experience indicates that a multidisciplinary team of clinicians and scientists can implement a paradigm in which WGA is integrated into the care of late stage cancer patients to inform systemic therapy decisions.

    2016-01-01

    With the development of industrialization and urbanization, heavy metals contamination has become a major environmental problem. Numerous investigations have revealed an association between heavy metal exposure and the incidence and mortality of gastric cancer. The mechanisms of heavy metals (lead, cadmium, mercury, chromium, and arsenic) contamination leading to gastric cancer are concluded in this review. There are four main potential mechanisms: (1) Heavy metals disrupt the gastric mucosal barrier by decreasing mucosal thickness, mucus content, and basal acid output, thereby affecting the function of E-cadherin and inducing reactive oxygen species (ROS) damage. (2) Heavy metals directly or indirectly induce ROS generation and cause gastric mucosal and DNA lesions, which subsequently alter gene regulation, signal transduction, and cell growth, ultimately leading to carcinogenesis. Exposure to heavy metals also enhances gastric cancer cell invasion and metastasis. (3) Heavy metals inhibit DNA damage repair or cause inefficient lesion repair. (4) Heavy metals may induce other gene abnormalities. In addition, heavy metals can induce the expression of proinflammatory chemokine interleukin-8 (IL-8) and microRNAs, which promotes tumorigenesis. The present review is an effort to underline the human health problem caused by heavy metal with recent development in order to garner a broader perspective.

    Highlights: •Identified stomach lineage specific gene set (SLSGS) was found to be under expressed in gastric tumors. •Elevated expression of SLSGS in gastric tumor is a molecular predictor of metabolic type gastric cancer. •In silico pathway scanning identified estrogen-α signaling is a putative regulator of SLSGS in gastric cancer. •Elevated expression of SLSGS in GC is associated with an overall increase in the survival of GC patients. -- Abstract: Stomach lineage specific gene products act as a protective barrier in the normal stomach and their expression maintains the normal physiological processes, cellular integrity and morphology of the gastric wall. However, the regulation of stomach lineage specific genes in gastric cancer (GC) is far less clear. In the present study, we sought to investigate the role and regulation of stomach lineage specific gene set (SLSGS) in GC. SLSGS was identified by comparing the mRNA expression profiles of normal stomach tissue with other organ tissue. The obtained SLSGS was found to be under expressed in gastric tumors. Functional annotation analysis revealed that the SLSGS was enriched for digestive function and gastric epithelial maintenance. Employing a single sample prediction method across GC mRNA expression profiles identified the under expression of SLSGS in proliferative type and invasive type gastric tumors compared to the metabolic type gastric tumors. Integrative pathway activation prediction analysis revealed a close association between estrogen-α signaling and SLSGS expression pattern in GC. Elevated expression of SLSGS in GC is associated with an overall increase in the survival of GC patients. In conclusion, our results highlight that estrogen mediated regulation of SLSGS in gastric tumor is a molecular predictor of metabolic type GC and prognostic factor in GC.

    Background Evidence that chemotherapy improves survival and quality of life in patients with stage IIIB & IV non small cell lung cancer (NSCLC) is based on large randomized controlled trials. The purpose of this study was to determine eligibility of patients with advanced NSCLC for major chemotherapy trials. Methods Physicians treating stage IIIB/IV NSCLC at Sydney Cancer Centre assessed patient eligibility for the E1594, SWOG9509 and TAX326 trials for patients presenting from October 2001 to December 2002. A review of the centre's registry was used to obtain missing data. Results 199 patients with advanced NSCLC were registered during the 14-month period. Characteristics of 100 patients were defined prospectively, 85 retrospectively: 77% males, median age 68 (range 32–88), 64% stage IV disease. Only 35% met trial eligibility for E1594 and 28% for SWOG9509 and TAX326. Common reasons for ineligibility were: co-morbidities 75(40%); ECOG Performance Status ≥2 72(39%); symptomatic brain metastasis 15(8%); and previous cancers 21(11%). Many patients were ineligible by more than one criterion. Conclusion The majority of patients with advanced NSCLC were ineligible for the large chemotherapy trials. The applicability of trial results to advanced lung cancer populations may be limited. Future trials should be conducted in a more representative population. PMID:19402889

    Objectives A fluoropyrimidine plus cisplatin combined with surgery is standard first-line treatment for advanced gastric cancer. We evaluated the effect of pravastatin on overall survival in patients with advanced gastric cancer in a prospective cohort study. Methods At the time of surgery, we assigned 60 patients with advanced gastric cancer (stage III or IV) to receive standard first-line treatment (control group) or standard first-line treatment plus pravastatin at a dose of 40 mg once daily (pravastatin group). The minimum follow-up period was 4 years and the maximum of 6 years. Results The mean of age was 66 years and the TNM stage was III and IV in 65% and 35% of patients, respectively. There was no significant difference between the two groups (control vs pravastatin) in median overall survival (15 vs 14 months; P = 0.8). Predictors of survival were the stage (hazard ratio of death stage IV (III stage as reference): 4.4; 95% CI: 2–9.7; p < 0.05) and older age (hazard ratio of death ≥ 65 years (< 65 years as reference): 2.8; 95% CI: 1.3–6; p < 0.05). Conclusions Pravastatin did not improve outcome in patients with advanced gastric cancer. PMID:26735890

    The process of formulating an accurate survival prediction is often difficult but important, as it influences the decisions of clinicians, patients, and their families. The current article aims to review the accuracy of clinicians' predictions of survival (CPS) in advanced cancer patients. A literature search of Cochrane CENTRAL, EMBASE, and MEDLINE was conducted to identify studies that reported clinicians' prediction of survival in advanced cancer patients. Studies were included if the subjects consisted of advanced cancer patients and the data reported on the ability of clinicians to predict survival, with both estimated and observed survival data present. Studies reporting on the ability of biological and molecular markers to predict survival were excluded. Fifteen studies that met the inclusion and exclusion criteria were identified. Clinicians in five studies underestimated patients' survival (estimated to observed survival ratio between 0.5 and 0.92). In contrast, 12 studies reported clinicians' overestimation of survival (ratio between 1.06 and 6). CPS in advanced cancer patients is often inaccurate and overestimated. Given these findings, clinicians should be aware of their tendency to be overoptimistic. Further investigation of predictive patient and clinician characteristics is warranted to improve clinicians' ability to predict survival.

    2013-03-01

    Persistent hiccup can cause anorexia, weight loss, disabling sleep deprivation, anxiety, and depression. Therefore, relief of persistent hiccup is important for advanced cancer patients and their family. Most reports on this condition are case series reports advocating the use of baclofen, haloperidol, gabapentin, and midazolam. However, these medications are occasionally ineffective or accompanied by intolerable side effects. The sodium channel blocker lidocaine has been shown to be effective in treating a variety of disorders thought to involve neuropathic mechanisms. Intravenous administration of lidocaine is common but efficacy has also been reported for subcutaneous infusion. In advanced cancer patients, subcutaneous infusion is easy, advantageous, and accompanied by less discomfort. We report a case of severe and sustained hiccup caused by gastric cancer that was successfully treated with a continuous subcutaneous infusion of lidocaine (480 mg (24 ml)/day) without severe side effects.

    We planned to determine the relationship between angiogenesis and p53 mutational status in advanced-stage epithelial ovarian cancer. Using 190 tumor samples from patients with stage III and IV ovarian cancer we performed p53 sequencing, immunohistochemistry, and CD31 microvessel density (MVD) determination. MVD was elevated in tumors with p53 null mutations compared to p53 missense mutation or no mutation. Disease recurrence was increased with higher MVD in both unadjusted and adjusted analyses. In adjusted analysis, p53 null mutation was associated with increased recurrence and worse overall survival. Worse overall survival and increased recurrence risk were also associated with the combination of CD31 MVD values >25 vessels/HPF and any p53 mutation. P53 mutation status and MVD may have prognostic significance in patients with advanced-stage ovarian cancer. Tumors with p53 null mutations are likely to be more vascular, contributing to decreased survival and increased recurrence probability.

    The development of immune checkpoint inhibitors has altered the landscape of treatment of advanced cancers. These drugs are well tolerated and have shown clinical activity against a wide variety of solid tumors and hematological malignancies. The durability of response is particularly impressive when compared to other forms of systemic therapy. Nivolumab (Opdivo) is an IgG4 antibody that causes immune checkpoint blockade by diminishing inhibitory signaling through the programmed death receptor-1 pathway. It is approved for treatment of recurrent non-small cell lung cancer, melanoma, and renal cell carcinoma. Efforts to identify biomarkers of response to nivolumab are ongoing. Clinical trials are also being conducted to determine the benefits of combining nivolumab with other forms of treatment including chemotherapy, molecular-targeted therapy, radiation therapy, and other forms of immune therapy. This review outlines the clinical trials that have led to the emergence of nivolumab as a treatment option for patients with advanced cancers.

    The era of “Big Data” presents opportunities to substantively address cancer prevention and control issues by improving health behaviors and refining theoretical models designed to understand and intervene in those behaviors. Yet, the terms “model” and “Big Data” have been used rather loosely, and clarification of these terms is required to advance the science in this area. The objectives of this paper are to discuss conceptual definitions of the terms “model” and “Big Data”, as well as examine the promises and challenges of Big Data to advance cancer prevention and control research using behavioral theories.

    Immunotherapy has a great potential in advancing cancer treatment, especially in light of recent discoveries and therapeutic interventions that lead to complete response in specific subgroups of melanoma patients. By using the body’s own immune system, it is possible not only to specifically target and eliminate cancer cells while leaving healthy cells unharmed but also to elicit long-term protective response. Despite the promise, current immunotherapy is limited and fails in addressing all tumor types. This is probably due to the fact that a single treatment strategy is not sufficient in overcoming the complex antitumor immunity. The use of nanoparticle-based system for immunotherapy is a promising strategy that can simultaneously target multiple pathways with the same kinetics to enhance antitumor response. Here, we will highlight the recent advances in the field of cancer immunotherapy that utilize lipid-based nanoparticles as delivery vehicles and address the ongoing challenges and potential opportunities.

    Imaging in the evaluation and follow-up of patients with early or advanced breast cancer is an important aspect of cancer care. The role of imaging in breast cancer depends on the goal and should only be performed to guide clinical decisions. Imaging is valuable if a finding will change the course of treatment and improve outcomes, whether this is disease-free survival, overall survival or quality-of-life. In the last decade, imaging is often overused in oncology and contributes to rising healthcare costs. In this context, we review the data that supports the appropriate use of imaging for breast cancer patients. We will discuss: 1) the optimal use of staging imaging in both early (Stage 0-II) and locally advanced (Stage III) breast cancer, 2) the role of surveillance imaging to detect recurrent disease in Stage 0-III breast cancer and 3) how patients with metastatic breast cancer should be followed with advanced imaging.

    The increased prevalence of autism spectrum disorder and documented benefits of early intensive intervention have created a need for flexible systems for determining eligibility for autism-specific services. This study evaluated the effectiveness of a training program designed to enhance autism spectrum disorder identification and assessment within community pediatric settings across the state. Twenty-seven pediatric providers participated in regional trainings across a 3.5-year period. Trainings provided clinicians with strategies for conducting relatively brief within-practice interactive assessments following positive autism spectrum disorder screenings. Program evaluation was measured approximately 1.5 years following training through (a) clinician self-reports of practice change and (b) blind diagnostic verification of a subset of children assessed. Pediatric providers participating in the training reported significant changes in screening and consultation practices following training, with a reported 85% increase in diagnostic identification of children with autism spectrum disorder within their own practice setting. In addition, substantial agreement (86%-93%) was found between pediatrician diagnostic judgments and independent, comprehensive blinded diagnostic evaluations. Collaborative training methods that allow autism spectrum disorder identification within broader community pediatric settings may help translate enhanced screening initiatives into more effective and efficient diagnosis and treatment.

    Consecutive cancer referrals to a palliative medicine program were evaluated to assess nutritional status using a standard protocol. The study included 352 patients (180 men, 172 women; median age 61 years, range 22-94 years). The most common diagnosis was lung cancer. All had metastatic disease, 139 with gastrointestinal involvement. The most common gastrointestinal symptoms were weight loss ( n=307), anorexia ( n=285), and early satiety ( n=243). Of those with any weight loss, 71% had lost >or0% of their pre-illness weight. The most common factor identified which might have contributed to weight loss was hypophagia ( n=275/307). Men had lost weight more often and to a greater extent than women. Triceps skinfold (TSF) was measured in 337: 51% had values that suggested severe fat deficiency. Upper mid-arm muscle area (AMA) was measured in 349: 30% had evidence of significant muscle mass reduction. The body mass index (BMI) was normal or increased in most patients. Calculated resting energy expenditure (REE) ( n=324) was high in 41%. C-reactive protein was elevated in 74% of those measured ( n=50). We conclude that: (1).most of this group of cancer patients referred to palliative medicine had severe weight loss; (2).there was a gender difference in the severity and type of weight loss; (3).males lost more weight overall and more muscle than females; (4).males with any degree of weight loss had a higher REE than females; (5).a significant correlation existed between the time from diagnosis to death and the severity of weight loss in the prior month; (6).BMI was normal in most patients, suggesting precancer diagnosis obesity; and (7).both TSF and AMA correlated well with body composition of both fat and protein as determined by bioelectrical impedance.

    BACKGROUND Programmed death 1 (PD-1) protein, a T-cell coinhibitory receptor, and one of its ligands, PD-L1, play a pivotal role in the ability of tumor cells to evade the host’s immune system. Blockade of interactions between PD-1 and PD-L1 enhances immune function in vitro and mediates antitumor activity in preclinical models. METHODS In this multicenter phase 1 trial, we administered intravenous anti–PD-L1 antibody (at escalating doses ranging from 0.3 to 10 mg per kilogram of body weight) to patients with selected advanced cancers. Anti–PD-L1 antibody was administered every 14 days in 6-week cycles for up to 16 cycles or until the patient had a complete response or confirmed disease progression. RESULTS As of February 24, 2012, a total of 207 patients — 75 with non–small-cell lung cancer, 55 with melanoma, 18 with colorectal cancer, 17 with renal-cell cancer, 17 with ovarian cancer, 14 with pancreatic cancer, 7 with gastric cancer, and 4 with breast cancer — had received anti–PD-L1 antibody. The median duration of therapy was 12 weeks (range, 2 to 111). Grade 3 or 4 toxic effects that investigators considered to be related to treatment occurred in 9% of patients. Among patients with a response that could be evaluated, an objective response (a complete or partial response) was observed in 9 of 52 patients with melanoma, 2 of 17 with renal-cell cancer, 5 of 49 with non–small-cell lung cancer, and 1 of 17 with ovarian cancer. Responses lasted for 1 year or more in 8 of 16 patients with at least 1 year of follow-up. CONCLUSIONS Antibody-mediated blockade of PD-L1 induced durable tumor regression (objective response rate of 6 to 17%) and prolonged stabilization of disease (rates of 12 to 41% at 24 weeks) in patients with advanced cancers, including non–small-cell lung cancer, melanoma, and renal-cell cancer.
