Versatility of Pedicled Perforator-Based V-Y Advancement Flaps for Reconstruction of the Upper Limb: A Case Series and Review of the Literature.

Introduction: The aim of any reconstruction is to provide a robust and cosmetically pleasing result that does not significantly alter function. We describe our experience of using the V-Y principle in advancement flaps designed around a distinct perforator to reconstruct soft tissue defects of the upper limb. The shortcomings of fasciocutaneous and fascial flaps requiring skin grafting can be eliminated.

Treatment completion, treatment compliance and outcomes of old and very old patients treated by dose adapted stereotactic ablative radiotherapy (SABR) for T1-T3N0M0 non-small cell lung cancer.

Aim: This is a retrospective single-institution review of the treatment completion and clinical outcomes of patients aged 75 and older, treated with stereotactic ablative body radiotherapy (SABR) for T1-T3 N0 M0 non-small cell lung cancer (NSCLC).

Methods: From April 2008 to September 2015, 200 patients, aged 75-93, received respiratory-managed, intensity-modulated-based SABR. Dose fractionation was risk-adapted and delivered in 2-3 weekly treatments.

Gene expression and epigenetic discovery screen reveal methylation of SFRP2 in prostate cancer.

Aberrant activation of Wnts is common in human cancers, including prostate. Hypermethylation associated transcriptional silencing of Wnt antagonist genes SFRPs (Secreted Frizzled-Related Proteins) is a frequent oncogenic event. The significance of this is not known in prostate cancer.
