Mucinous type of epithelial ovarian cancer (MuOC) is a unique subtype with a poor survival outcome in recurrent and advanced stages. The role of type-specific epigenomics and its clinical significance remain uncertain. We analyzed the methylomic profiles of six benign mucinous adenomas, 24 MuOCs, 103 serous type of epithelial ovarian cancers (SeOCs), and 337 nonepithelial ovarian cancers. MuOC and SeOC exhibited distinct DNA methylation profiles comprising 101 genes, 81 of which exhibited low methylation in MuOC and were associated with the response to glucocorticoid, ATP hydrolysis-coupled proton transport, proteolysis involved in the cellular protein catabolic process, and ion transmembrane transport...

Background: Germline mutations in succinate dehydrogenase (SDH) are associated with multifocal cancers: pituitary gland tumors, pheochromocytomas, paragangliomas, gastrointestinal stromal tumors, and renal-cell carcinomas (RCCs). SDH-deficient renal-cell carcinoma (SDH-RCC) was first identified in 2004 as an inherited kidney cancer with mutations in the SDH gene. SDH consists of A, B, C, and D units. Mutation in the SDHB gene is the most common mutation in SDH-deficient RCCs. Case Presentation: We report a case of a 51-year-old healthy man diagnosed with SDHB germline mutation and RCCs...

Gastric metastasis by solid tumor cancer is a rare event. Concomitant metastases to other organs are frequent, so that this condition is often associated to a poor prognosis. Upper gastrointestinal bleeding and anemia are the most common presenting symptoms. We present the case of a 81 years old women previously treated for cervix carcinoma showing later a stomach metastasis. The patient is alive and disease free 39 months after salvage gastrectomy. A radical surgery in selected patients could be useful for symptom palliation and prolonged survival...

Background: Capecitabine is an approved standard therapy for anthracycline- and taxane-pretreated locally advanced or metastatic breast cancer (BC). Vinflunine has demonstrated single-agent activity in phase II studies in this setting, and activity and tolerability when combined with capecitabine. We compared the combination of vinflunine plus capecitabine (VC) with single-agent capecitabine. Patients and methods: Patients with locally recurrent/metastatic BC previously treated or resistant to an anthracycline and resistant to taxane therapy were randomly assigned to either vinflunine (280 mg/m2, day 1) plus oral capecitabine (825 mg/m2 twice daily [bid], days 1-14) every 3 weeks (q3w) or single-agent oral capecitabine (1250 mg/m2 bid, days 1-14) q3w...

GnRH antagonists have several clinical applications in prostate cancer, regulation of ovulation induction in females, breast cancer, male contraception and others. Antagonists differ from natural GnRH decapeptide in having five or more amino acid substitutions. Whereas most of antagonists are available as subcutaneous (SC) formula for injection, some are formulated as a depot formulation for sustained release (e.g. Cetrarelix, Degarelix). Systemic delivery of cetrorelix acetate by intratracheal route can be achieved using dry powder for inhalation of adhesive mixture when the powder deposition reaches stage four...

BACKGROUND: Life expectancy at birth (LE) is a comprehensive measure that accounts for age-specific death rates in a population. Shanghai has ranked first in LE in China mainland for decades. Understanding the reasons behind its sustained gain in LE provides a good reflection of many other cities in China. The aim of this study is intended to explore temporal trend in age- and cause-specific gains in LE in Shanghai and the probable reasons lay behind. METHODS: Joinpoint regression was applied to evaluate temporal trend in LE and the long time span was then divided accordingly...

PURPOSE: Previous studies reported promising efficacy for celecoxib in the treatment of cancer cachexia. We designed this study to test the hypothesis that combination therapy with megestrol acetate (MA) plus celecoxib is superior to MA alone. METHODS: Ninety eligible gastrointestinal cancer patients randomly received either MA 320 mg/day plus placebo (arm1) or MA 320 mg/day plus celecoxib 200 mg/day (arm2). Patients were evaluated at baseline, then 1 and 2 months after starting interventions...

We evaluated the effect of continuous perfusion of esmolol on cardiovascular risk during curative laparoscopic surgery for gastrointestinal cancer in elderly patients. Sixty patients with gastrointestinal cancer, aged from 60 to 80 years, were divided into an esmolol group (ES, n = 30) and a control group (NS, n = 30). ES patients were treated with esmolol at a dose of 0.3 mg/kg 3 min before tracheal intubation, and received continuous perfusion of esmolol at a dose of 50 μg/kg/min during operation. In NS, esmolol was replaced by saline...

Immune checkpoint blockers have revolutionized cancer treatment in recent years. These agents are now approved for the treatment of several malignancies, including melanoma, squamous and non-squamous non-small cell lung cancer, renal cell carcinoma, urothelial carcinoma, and head and neck squamous cell carcinoma. Studies have demonstrated the significant impact of immunotherapy versus standard of care on patient outcomes, including durable response and extended survival. The use of immunotherapy-based combination therapy has been shown to further extend duration of response and survival...

Gastrointestinal (GI) tract metastasis of primary breast cancer is very rare. We present a patient with small bowel obstruction from distant metastasis of primary breast cancer. Each characteristic features of concern of GI tract distant metastasis from many pervious studies has been reported differently. We should remember that GI tract metastasis may coexist when patients with breast cancer have intermittent or recurrent abdominal pain with or without obstructive symptoms.

Cigarette smoking is a major risk factor for gastrointestinal disorders, such as peptic ulcer, Crohn's disease (CD), and several cancers. The mechanisms proposed to explain the role of smoking in these disorders include mucosal damage, changes in gut irrigation, and impaired mucosal immune response. Paradoxically, cigarette smoking is a protective factor for the development and progression of ulcerative colitis (UC). UC and CD represent the two most important conditions of inflammatory bowel diseases, and share several clinical features...

Evolution of targeted therapy has changed the spectrum of treatment in oncology since the past two decades as lots of newer agents are being added to the pharmacologic armamentarium of cancer therapy. Epidermal growth factor receptor inhibitors form one such advancing field with many newer agents being investigated and they are used in wide variety of malignancies such as head and neck cancer, lung cancer, and even gastrointestinal malignancies such as pancreatic cancer. Various troublesome side effects of these agents include diarrhea, severe fatigability, severe skin rashes, and deranged liver function tests which may require treatment interruption or dose reduction resulting in decreased response to treatment...

Background: Streptococcus gallolyticus ssp. gallolyticus (Sgg) is a commensal bacterium and an opportunistic pathogen. In humans it has been clinically associated with the incidence of colorectal cancer (CRC) and epidemiologically recognized as an emerging cause of infective endocarditis (IE). The standard therapy of Sgg includes the administration of a penicillin in combination with an aminoglycoside. Even though penicillin-resistant isolates have still not been reported, epidemiological studies have shown that this microbe is a reservoir of multiple acquired genes, conferring resistance to tetracyclines, aminoglycosides, macrolides and glycopeptides...

Pain is a common symptom in many types of cancer. Interdisciplinary team management, including pain assessment, explanation to the patient/family, treating the reversible, non-pharmacological treatments and reassessment are essential. This article focuses on the pharmacological management of cancer pain, and overviews and updates on the recent advances in this field. Both non-opioid and opioid analgesia as well as coanalgesics (adjuvants) are reviewed. Within non-opioid analgesia the risks of non-steroidal anti-inflammatory drugs (NSAIDs) are considered and recommendations for NSAIDs in patients at risk of gastrointestinal and cardiovascular toxicity are made...
