Review Meta AnalysisRisk of bleeding with vascular endothelial growth factor receptor tyrosine-kinase inhibitors sunitinib and sorafenib: a systematic review and meta-analysis of clinical trials.
Sunitinib and sorafenib are oral vascular endothelial growth factor receptor (VEGFR) tyrosine-kinase inhibitors used in various cancers. Bleeding has been described with these agents, although the overall risk remains unclear. We did a systematic review and meta-analysis to calculate the incidence and relative risk associated with use of sunitinib and sorafenib. ⋯ None.

At least 15% of human malignant diseases are attributable to the consequences of persistent viral or bacterial infection. Chronic infection with oncogenic human papillomavirus (HPV) types is a necessary, but insufficient, cause in the development of more cancers than any other virus. ⋯ However, because a proportion of intraepithelial HPV-associated disease undergoes immune-mediated regression, the development of immunotherapeutic strategies is an opportunity to determine proof-of-principle for therapeutic vaccines. In this Review, we discuss recent progress in this field and priorities for future clinical investigations.

ReviewTreatment advances for medically inoperable non-small-cell lung cancer: emphasis on prospective trials.
Advances in technology have changed the treatment of patients with early stage non-small-cell lung cancer who are not healthy enough for standard surgical resection. Previously, patients with severe underlying cardiopulmonary dysfunction were often dissuaded from pursuing definitive therapy, even though most patients died from their lung cancer and not as a result of comorbid medical illness. ⋯ This Review focuses on the management of these patients, including use of conformal radiotherapy, stereotactic body radiation therapy, sublobar resection, intraoperative brachytherapy, and radiofrequency ablation. Ongoing challenges are presented and prospective data are emphasised.

ReviewGenotype-guided tamoxifen therapy: time to pause for reflection?
Tamoxifen remains a cornerstone of adjuvant therapy for patients with early stage breast cancer and oestrogen-receptor-positive tumours. Accurate markers of tamoxifen resistance would allow prediction of tamoxifen response and personalisation of combined therapies. Recently, it has been suggested that patients with inherited non-functional alleles of the cytochrome P450 CYP2D6 might be poor candidates for adjuvant tamoxifen therapy, because women with these variant alleles have reduced concentrations of the tamoxifen metabolites that most strongly bind the oestrogen receptor. ⋯ None of the explanations proposed for the heterogeneity of these results adequately account for the variability and no design feature sets apart any study or subset of studies as most likely to be accurate. The studies reporting a positive association might receive the most attention, because they report a result consistent with the profile of metabolite concentrations; not because they are more reliable by design. We argue that a recommendation for CYP2D6 genotyping of candidates for tamoxifen therapy, and its implicit conclusion regarding the association between genotype and recurrence risk, is premature.
