Three-week hypofractionated radiotherapy in early glottic cancer-a single institution retrospective study.

Background: Radiotherapy is a standard treatment option for early glottic carcinoma (stage I and II) with a fraction size of 2-2.2 Gy over 5-7 weeks. This study evaluates the outcome and prognostic factors of a 3-week hypofractionated treatment in early glottic malignancy.

Tumor collection/processing under physioxia uncovers highly relevant signaling networks and drug sensitivity.

Preclinical studies of primary cancer cells are typically done after tumors are removed from patients or animals at ambient atmospheric oxygen (O, ~21%). However, O concentrations in organs are in the ~3 to 10% range, with most tumors in a hypoxic or 1 to 2% O environment in vivo. Although effects of O tension on tumor cell characteristics in vitro have been studied, these studies are done only after tumors are first collected and processed in ambient air.

A Priori Activation of Apoptosis Pathways of Tumor (AAAPT) technology: Development of targeted apoptosis initiators for cancer treatment.

Cancer cells develop tactics to circumvent the interventions by desensitizing themselves to interventions. Amongst many, the principle routes of desensitization include a) activation of survival pathways (e.g.

Sarcopenia in cancer: Risking more than muscle loss.

Sarcopenia is characterised by progressive and extensive skeletal muscle degeneration and is associated with functional decline. Sarcopenia has primary and secondary aetiology, arising as a result of the ageing process or through chronic cytokine-mediated inflammation (associated with health conditions including cancer), respectively. Diagnosis of sarcopenia is dependent upon detection of reduced skeletal muscle strength, mass and performance.

Breast Heterogeneity: Obstacles to Developing Universal Biomarkers of Breast Cancer Initiation and Progression.

Background: Predicting outcomes and response to therapy through biomarkers is a major challenge in cancer research. In previous studies, we suggested that inappropriate "normal" tissue samples used for comparison with tumors, inter-individual heterogeneity in gene expression, and genetic ancestry all influence biomarker expression in tumors. The aim of this study was to investigate these factors in breast cancer using breast tissues from healthy women and normal tissue adjacent to tumor (NAT) with matrix metalloproteinase 7 (MMP7) as a candidate biomarker.
