Prostate Int 2021 Mar 13;9(1):54-59. Epub 2020 Aug 13.

Latin American Cooperative Oncology Group (LACOG), Genito-Urinary Section, Brazil.

Background: According to pathologico-clinical features, patients diagnosed with localized prostate cancer (PCa) are stratified into distinct risk groups (low-risk, intermediate-risk or high-risk). Data have demonstrated that Gallium-prostate-specific membrane antigen positron emission tomography (Ga-PSMA PET/CT) is superior to conventional radiological exams (CT or MRI and bone scintigraphy) in the primary staging of high-risk localized PCa. However, it is still unknown if in a population of high-risk PCa, there would be a subgroup of patients with a higher probability of identifying metastatic disease by the Ga-PSMA PET/CT. Read More

A cross-sectional study on gut microbiota in prostate cancer patients with prostatectomy or androgen deprivation therapy.

Prostate Cancer Prostatic Dis 2021 Apr 13. Epub 2021 Apr 13.

S.H. Ho Urology Centre, Department of Surgery, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong, China.

Background: Androgen deprivation therapy (ADT), either by medical or surgical castration, is the backbone for standard treatment of locally advanced or metastatic prostate cancer, yet it is also associated with various metabolic and cardiovascular complications. Recent evidence have shown that obesity, insulin resistance, or metabolic disturbances can be associated with changes in the gut microbiome, while animal studies also show that castration is associated with changes in the gut microbiome. This study aims to investigate whether the fecal microbiota in prostate cancer patients who had undergone prostatectomy or ADT are different, and explore changes in phylogeny and pathways that may lead to side effects from ADT.

Telomere Length Dynamics and Chromosomal Instability for Predicting Individual Radiosensitivity and Risk via Machine Learning.

J Pers Med 2021 Mar 8;11(3). Epub 2021 Mar 8.

Department of Environmental and Radiological Health Sciences, Colorado State University, Fort Collins, CO 80523, USA.

The ability to predict a cancer patient's response to radiotherapy and risk of developing adverse late health effects would greatly improve personalized treatment regimens and individual outcomes. Telomeres represent a compelling biomarker of individual radiosensitivity and risk, as exposure can result in dysfunctional telomere pathologies that coincidentally overlap with many radiation-induced late effects, ranging from degenerative conditions like fibrosis and cardiovascular disease to proliferative pathologies like cancer. Here, telomere length was longitudinally assessed in a cohort of fifteen prostate cancer patients undergoing Intensity Modulated Radiation Therapy (IMRT) utilizing Telomere Fluorescence in situ Hybridization (Telo-FISH).
