Differentiated thyroid carcinoma: what the nonspecialists needs to know.

Differentiated thyroid carcinoma (DTC) accounts for most cases of thyroid cancer, and the heterogeneity of DTC requires that management decisions be taken by a multidisciplinary team involving endocrinologists, head and neck surgeons, nuclear medicine physicians, pathologists, radiologists, radiation oncologists, and medical oncologists. It is important for nonspecialists to recognize and refer patients with DTC who will benefit from a specialized approach. Recent advances in knowledge and changes in management of DTC call for the need to raise awareness on the part of these nonspecialist physicians, including general endocrinologists and medical oncologists at large.

Metformin plus lrinotecan in patients with refractory colorectal cancer: a phase 2 clinical trial.

Background: Patients with refractory colorectal (CRC) cancer have few treatment options. This trial tests the combination of metformin and irinotecan in this setting.

Methods: A phase 2 single-arm trial was conducted, patients received metformin 2500 mg orally a day plus irinotecan 125 mg/m intravenously weekly D1 and D8 every 21 days.

VEGF-A levels in bevacizumab-treated breast cancer patients: a systematic review and meta-analysis.

Bevacizumab may improve outcomes of patients with breast cancer, but the absence of an established biomarker hampers patient selection and researchers´ ability to demonstrate a clear survival benefit. Its putative target, circulating VEGF-A, emerged as the main candidate and we sought to identify the relationship between VEGF-A levels and outcomes through systematic review. We searched electronic databases and meeting proceedings for randomized controlled trials (RCTs) comparing the addition of bevacizumab to standard chemotherapy for breast cancer.

Prevention strategies for chemotherapy-induced hand-foot syndrome: a systematic review and meta-analysis of prospective randomised trials.

Purpose: Hand-foot syndrome (HSF) is a distinctive adverse event relatively frequent to some chemotherapeutic agents as capecitabine, pegylated liposomal doxorubicin, sorafenib and other tyrosine-kinase inhibitors. Since the prevention of HFS would be crucial to avoid treatment interruptions and delays, many studies have been conducted with this purpose.

Methods: The aim of this systematic review and meta-analysis was to analyze the clinical efficacy of prevention strategies for HFS, through a wide search of electronic databases as well as congress abstracts.

Imatinib-induced bone edema: case report and review of literature.

Imatinib mesylate represents a revolution in the management of patients with metastatic gastrointestinal stromal tumors (GISTs). More recently, postoperative imatinib has been shown to improve both disease-free and overall survivals in patients with a high risk of recurrence. This article presents a well-documented case of a patient with painful and reversible bone edema related to imatinib.

Ramucirumab monotherapy for previously treated advanced gastric or gastro-oesophageal junction adenocarcinoma (REGARD): an international, randomised, multicentre, placebo-controlled, phase 3 trial.

Background: Vascular endothelial growth factor (VEGF) and VEGF receptor-2 (VEGFR-2)-mediated signalling and angiogenesis can contribute to the pathogenesis and progression of gastric cancer. We aimed to assess whether ramucirumab, a monoclonal antibody VEGFR-2 antagonist, prolonged survival in patients with advanced gastric cancer.

Methods: We did an international, randomised, double-blind, placebo-controlled, phase 3 trial between Oct 6, 2009, and Jan 26, 2012, at 119 centres in 29 countries in North America, Central and South America, Europe, Asia, Australia, and Africa.

Neurokinin-1 receptor antagonists for chemotherapy-induced nausea and vomiting: a systematic review.

Background: The addition of neurokinin-1 receptor (NK1R) antagonists to antiemetic regimens has substantially reduced chemotherapy-induced nausea and vomiting (CINV). We sought to systematically review the overall impact of NK1R antagonists on CINV prevention.

Methods: We systematically searched the MEDLINE, EMBASE, and CENTRAL databases, and meeting proceedings for randomized controlled trials (RCTs) that evaluated NK1R antagonists plus standard antiemetic therapy for CINV prevention.

Is there a role for consolidative radiotherapy in the treatment of aggressive and localized non-Hodgkin lymphoma? A systematic review with meta-analysis.

Background: Chemotherapy is the mainstay of non-Hodgkin lymphoma (NHL) treatment. Based on expert opinion, the use of radiotherapy (RT) is currently preferred in some institutions as consolidative treatment for patients with localized disease. The lack of conclusive data coming from conflicting studies about the impact of treatment demands a systematic review, which could provide the most reliable assessment for clinical decision-making.

Independent radiologic review in metastatic colorectal cancer: systematic review and meta-analysis.

Purpose: To perform a meta-analysis addressing evaluation bias in local radiologic assessment (LRA) of lesions when compared with independent radiologic review (IRR) in randomized controlled trials (RCTs) testing chemotherapy for metastatic colorectal cancer (CRC).

Materials And Methods: MEDLINE, EMBASE, ClinicalTrials.gov, the Cochrane Library, and Web sites for major medical meetings were searched for RCTs of chemotherapy for metastatic CRC that reported response evaluation by both LRA and IRR.

Bevacizumab in metastatic colorectal cancer and carcino-embryonic antigen kinetics: case report and review of literature.

Bevacizumab-containing treatment is one of the approved first-line options for the management of metastatic colorectal cancer (CRC). Carcino-embryonic antigen (CEA) is a reasonable tumour marker for monitoring the efficacy of treatment. We report here a case of a 58-year-old male patient with metastatic CRC.

Japanese patients equally likely to benefit from aprepitant for chemotherapy-induced nausea and vomiting prevention.

Camptothecins compared with etoposide in combination with platinum analog in extensive stage small cell lung cancer: systematic review with meta-analysis.

Introduction: Superiority of camptothecin regimens over etoposide-both combined with platinum analogs-in extensive disease small cell lung cancer has been a matter of debate with contradictory findings in randomized trials. A systematic review was sought to elucidate this issue.

Methods: Randomized controlled trials comparing first-line camptothecin-platinum doublets versus etoposide-platinum doublets in patients with extensive disease small cell lung cancer were searched in MEDLINE, EMBASE, LILACS, and CENTRAL databases, European Society of Medical Oncology, American Society of Clinical Oncology, and International Association for the Study of Lung Cancer meeting sites.

Optimal duration of first-line chemotherapy for advanced non-small cell lung cancer: a systematic review with meta-analysis.

Background: The optimal duration of first-line chemotherapy for advanced non-small cell lung cancer (NSCLC) has been a matter for debate for nearly 20 years. In order to elucidate this issue, a meta-analysis comparing the different durations of same treatments was performed.

Methods: We searched for all published randomised controlled trials (RCTs) comparing different durations of first-line treatment of advanced NSCLC.
