Pancreatic cancer is the fourth leading cause of cancer-related death worldwide. Gemcitabine is the mainstay treatment for advanced disease. However, almost all up-to-date trials, that evaluated the benefit of gemcitabine-combination schedules, failed to demonstrate an improvement in overall survival (OS). In this study, we performed a systematic review and a meta-analysis of randomised clinical trials (RCTs) to investigate the efficacy and safety of gemcitabine-based combination regimens as compared to gemcitabine alone in the management of pancreatic cancer. ⋯ The combination chemotherapy as compared to gemcitabine alone significantly improves OS in advanced pancreatic cancer (APC). However, this advantage is marginal whereas the treatment-related toxicity is increased, suggesting the use of gemcitabine-based combination regimens only in selected patient populations. New prospective trials, based on translational approaches and innovative validated biomarkers, are eagerly awaited on this topic.

Little is known about the prevalence and clinical significance of heterogeneity of positron emission tomography with (18)F-labelled fluorodeoxyglucose-positron emission tomography (FDG-PET) response. We aim to determine the prevalence, and clinicopathologic correlates of intra-patient heterogeneity of FDG-PET response in metastatic melanoma treated with dabrafenib, and to determine whether heterogeneity predicts clinical outcome. ⋯ Heterogeneous FDG-PET responses are common in metastatic melanoma treated with dabrafenib, and heterogeneity is associated with a shorter TTP. FDG-PET heterogeneity may predict molecular heterogeneity, and FDG-PET directed biopsies may facilitate investigation into mechanisms of resistance to signal pathway inhibitors.

Randomized Controlled Trial Multicenter Study
A double-blind, randomised, placebo-controlled, phase 2b study evaluating sorafenib in combination with paclitaxel as a first-line therapy in patients with HER2-negative advanced breast cancer.
We conducted a phase 2b, randomised, double-blind, placebo-controlled screening trial to evaluate the addition of the multikinase inhibitor sorafenib (antiproliferative/antiangiogenic) to first-line paclitaxel for human epidermal growth factor receptor 2 (HER2)-negative locally recurrent/metastatic breast cancer. ⋯ The addition of sorafenib to paclitaxel improved disease control but did not significantly improve PFS to support a phase 3 trial of similar design. Toxicity of the combination was manageable with dose reductions.

Randomized Controlled Trial Multicenter Study
Adjuvant therapy with pegylated interferon alfa-2b (36 months) versus low-dose interferon alfa-2b (18 months) in melanoma patients without macrometastatic nodes: an open-label, randomised, phase 3 European Association for Dermato-Oncology (EADO) study.
Both low-dose interferon (IFN) alfa-2b and pegylated interferon (Peg-IFN) alfa-2b have been shown to be superior to observation in the adjuvant treatment of melanoma without macrometastatic nodes, but have never been directly compared. Peg-IFN facilitates prolongation of treatment, which could provide additional benefit. This multicentre, open-label, randomised, phase 3 trial compared standard low-dose interferon IFN and prolonged treatment with Peg-IFN. ⋯ This trial did not show superiority for adjuvant Peg-IFN over conventional low-dose IFN in melanoma patients without clinically detectable nodes. ClinicalTrials.gov identifier: NCT00221702.

Multicenter Study
Cabazitaxel in patients with advanced solid tumours: results of a Phase I and pharmacokinetic study.
Although the taxanes paclitaxel and docetaxel are among the most active agents for the treatment of a wide range of cancers, tumours often develop resistance to these treatments. Cabazitaxel is a novel taxane active in both preclinical models of chemotherapy-sensitive and -resistant human tumours and patients with advanced prostate cancer that progressed following docetaxel treatment. ⋯ The 25mg/m(2) dose of cabazitaxel was recommended for use in future clinical studies. In this study, cabazitaxel had an acceptable tolerability profile and activity in cervical, colorectal, endometrial and lung cancers.
