Background Due to its high incidence, prostate cancer (PC) imposes a burden on Western societies. Individualized treatment decision for nonmetastatic PC (eg, surgery, radiation, focal therapy, active surveillance, watchful waiting) is challenging. The range of options might make affected persons seek peer-to-peer counseling. Besides traditional face-to-face support groups (F2FGs), online (OSGs) became important, especially during COVID-19. Objective This study aims investigate utilization...

Proton radiotherapy has been implemented into the standard-of-care for cancer patients within recent years. However, experimental studies investigating cellular and molecular mechanisms are lacking, prognostic biomarkers needed. Cancer stem cell (CSC)-related biomarkers, such as aldehyde dehydrogenase (ALDH), known to influence radiosensitivity through inactivation of reactive oxygen species, DNA damage repair, death. In a previous study, we found that ionizing radiation itself enriches...
