The prognostic significance of sarcopenia in patients treated with definitive radiotherapy: A systematic review.

Sarcopenia describes the degenerative loss of muscle mass and strength, and is emerging as a pan-cancer prognostic biomarker. It is linked with increased treatment toxicity, decreased survival and significant healthcare financial burden. Systematic analyses of sarcopenia studies have focused on outcomes in patients treated surgically or with systemic therapies.

Hypoxia-Associated Gene Signatures Are Not Prognostic in High-Risk Localized Prostate Cancers Undergoing Androgen Deprivation Therapy With Radiation Therapy.

Purpose: Men with high-risk prostate cancer (PCa) are treated with androgen deprivation therapy (ADT) and radiation therapy, but the disease reoccurs in 30% of patients. Biochemical recurrence of PCa after treatment is influenced by tumor hypoxia. Tumors with high levels of hypoxia are aggressive, resistant to treatment, and have increased metastatic capacity.

Brief report on the clinical characteristics of patients whose samples generate small cell lung cancer circulating tumour cell derived explants.

Introduction: Small cell lung cancer (SCLC) has a dismal prognosis. Circulating tumour cells (CTCs) can be used to generate CTC derived explants (CDX) for the study of SCLC biology and the development of novel therapeutics. We investigated whether there are demographic or clinical predictors of the success of CDX generation, and whether CDX models are representative of the SCLC patient population.

Does magnetic resonance imaging improve soft tissue sarcoma contouring for radiotherapy?

Objective: Soft tissue sarcomas (STS) are a rare, heterogeneous tumour group. Radiotherapy improves local control. CT is used to plan radiotherapy, but has poor soft tissue definition.

Utility of ctDNA to support patient selection for early phase clinical trials: the TARGET study.

Next-generation sequencing (NGS) of circulating tumor DNA (ctDNA) supports blood-based genomic profiling but is not yet routinely implemented in the setting of a phase I trials clinic. TARGET is a molecular profiling program with the primary aim to match patients with a broad range of advanced cancers to early phase clinical trials on the basis of analysis of both somatic mutations and copy number alterations (CNA) across a 641 cancer-associated-gene panel in a single ctDNA assay. For the first 100 TARGET patients, ctDNA data showed good concordance with matched tumor and results were turned round within a clinically acceptable timeframe for Molecular Tumor Board (MTB) review.
