Comparative StudyPrognostic value of a microRNA signature in nasopharyngeal carcinoma: a microRNA expression analysis.
MicroRNAs (miRNAs) can be used as prognostic biomarkers in many types of cancer. We aimed to identify miRNAs that were prognostic in patients with nasopharyngeal carcinoma. ⋯ Science Foundation of Chinese Ministry of Health, National Natural Science Foundation of China, Pearl River Scholar Funded Scheme, Guangdong Key Scientific and Technological Innovation Program, Guangdong Natural Science Foundation, Fundamental Research Funds for the Central Universities.

Randomized Controlled Trial Multicenter Study Comparative StudyChemoradiotherapy with capecitabine versus fluorouracil for locally advanced rectal cancer: a randomised, multicentre, non-inferiority, phase 3 trial.
Fluorouracil-based chemoradiotherapy is regarded as a standard perioperative treatment in locally advanced rectal cancer. We investigated the efficacy and safety of substituting fluorouracil with the oral prodrug capecitabine. ⋯ Roche Pharma AG (Grenzach-Wyhlen, Germany).

Since the identification of microRNAs (miRNAs) in 1993, and the subsequent discovery of their highly conserved nature in 2000, the amount of research into their function--particularly how they contribute to malignancy--has greatly increased. This class of small RNA molecules control gene expression and provide a previously unknown control mechanism for protein synthesis. As such, it is unsurprising that miRNAs are now known to play an essential part in malignancy, functioning as tumour suppressors and oncogenes. This Review summarises the present understanding of how miRNAs operate at the molecular level; how their dysregulation is a crucial part of tumour formation, maintenance, and metastasis; how they can be used as biomarkers for disease type and grade; and how miRNA-based treatments could be used for diverse types of malignancies.

ReviewShort-term androgen deprivation therapy for patients with intermediate-risk prostate cancer undergoing dose-escalated radiotherapy: the standard of care?
What is the best way to manage patients with intermediate-risk prostate cancer? One of the most controversial aspects of treatment is the role of short-term androgen deprivation therapy in combination with definitive radiotherapy. In two randomised trials of patients with mostly intermediate-risk prostate cancer, increased overall survival was reported when short-term androgen deprivation therapy was added to radiotherapy. ⋯ This limitation, in combination with the heterogeneous nature of the cancers classified as intermediate risk, has complicated the application of these trial results to modern clinical practice. In this Review, we discuss clinical evidence for and against use of short-term androgen deprivation therapy with dose-escalated radiotherapy for patients with intermediate-risk prostate cancer.
