Randomized Controlled Trial Multicenter StudyMetformin in patients with advanced pancreatic cancer: a double-blind, randomised, placebo-controlled phase 2 trial.
In preclinical work and retrospective population studies, the anti-diabetic drug metformin has been associated with antineoplastic activity and decreased burden of many cancers, including pancreatic cancer. There is therefore interest in the hypothesis that this drug might be repurposed for indications in oncology. We aimed to assess the efficacy of the addition of metformin to a standard systemic therapy in patients with advanced pancreatic cancer, and provide the first report of a clinical trial with a survival endpoint of metformin for an oncological indication. ⋯ Academic Medical Centre, Amsterdam, and The Terry Fox Foundation, Vancouver, Canada.

Randomized Controlled Trial Comparative StudyPatient-reported outcomes with adjuvant exemestane versus tamoxifen in premenopausal women with early breast cancer undergoing ovarian suppression (TEXT and SOFT): a combined analysis of two phase 3 randomised trials.
The combined efficacy analysis of the TEXT and SOFT trials showed a significant disease-free survival benefit with exemestane plus ovarian function suppression (OFS) compared with tamoxifen plus OFS. We present patient-reported outcomes from these trials. ⋯ Pfizer, International Breast Cancer Study Group, and US National Cancer Institute.

ReviewContinued value of adjuvant anthracyclines as treatment for early breast cancer.
Anthracyclines are frequently used in the adjuvant treatment of early-stage breast cancer. However, with the increasing use of other active drugs--mainly taxanes and trastuzumab in HER2-positive disease--coupled with concerns about anthracycline-associated toxic effects, there is debate about whether anthracyclines are still needed. Three major factors should be taken into consideration with the investigation of the role of anthracyclines in management of early breast cancer; specifically, the proven efficacy of anthracyclines in breast cancer, the absence of superiority of non-anthracycline-based chemotherapy over anthracycline-taxane regimens, and the low risk of toxic effects associated with the cumulative doses of anthracyclines used in contemporary regimens. The risks remain substantially outweighed by the benefits of treatment with anthracyclines, and thus, they maintain an important role in adjuvant treatment of breast cancer, particularly in women with high-risk disease.

Treatment for non-small-cell lung cancer is evolving from the use of cytotoxic chemotherapy to personalised treatment based on molecular alterations. This past decade has witnessed substantial progress in the treatment of patients with EGFR mutations and ALK rearrangements, and it is now possible to study complex genomic alterations in cancer using next-generation sequencing. ⋯ These data clearly suggest that lung adenocarcinoma is associated with distinct genomic alterations compared with other lung cancer subtypes, and highlight the widespread molecular heterogeneity that underlies the disease. In this Review, we discuss some of the key findings from genomic studies of lung adenocarcinoma.

Comparative Study Clinical TrialLocal radiotherapy and granulocyte-macrophage colony-stimulating factor to generate abscopal responses in patients with metastatic solid tumours: a proof-of-principle trial.
An abscopal response describes radiotherapy-induced immune-mediated tumour regression at sites distant to the irradiated field. Granulocyte-macrophage colony-stimulating factor is a potent stimulator of dendritic cell maturation. We postulated that the exploitation of the pro-immunogenic effects of radiotherapy with granulocyte-macrophage colony-stimulating factor might result in abscopal responses among patients with metastatic cancer. ⋯ New York University School of Medicine's Department of Radiation Oncology and Cancer Institute.
