Background And Objective: The use and duration of androgen deprivation therapy (ADT) with postoperative radiotherapy (RT) have been uncertain. RADICALS-HD compared adding no ("None"), 6-months ("Short"), or 24-mo ("Long") ADT to study efficacy in the long term.
Methods: Participants with prostate cancer were indicated for postoperative RT and agreed randomisation between all durations.
Article Synopsis
- A clinical trial called RADICALS-HD studied the effects of adding short-course androgen deprivation therapy (ADT) to postoperative radiotherapy in patients with localized prostate cancer after surgery.
- It involved 1480 patients, examining how ADT impacts metastasis-free survival compared to radiotherapy alone, and measured outcomes like distant metastasis and overall survival.
- The trial aimed to see if combining ADT with radiotherapy could improve the 10-year metastasis-free survival rate, potentially increasing it from 80% to 86%.
Article Synopsis
- The study investigates the effectiveness and optimal duration of androgen deprivation therapy (ADT) combined with postoperative radiotherapy for patients with localized prostate cancer following radical prostatectomy.
- A randomised controlled trial, RADICALS-HD, compared short-course ADT (6 months) to long-course ADT (24 months) among participants who met specific criteria, including PSA levels and absence of metastatic disease.
- The primary outcome measured was metastasis-free survival, with the trial aiming to determine if longer ADT duration leads to better survival rates, involving over 1,500 patients from 2008 to 2015.
Background: The optimal timing of radiotherapy (RT) after radical prostatectomy for prostate cancer has been uncertain. RADICALS-RT compared efficacy and safety of adjuvant RT versus an observation policy with salvage RT for prostate-specific antigen (PSA) failure.
Patients And Methods: RADICALS-RT was a randomised controlled trial enrolling patients with ≥1 risk factor (pT3/4, Gleason 7-10, positive margins, preoperative PSA≥10 ng/ml) for recurrence after radical prostatectomy.
Most environments exhibit predictable yearly changes, permitting animals to anticipate them. The hypothalamic-pituitary-adrenal (HPA) axis is a key physiological pathway that enables animals to cope with such changes. Monitoring glucocorticoid (the end products of the HPA axis) levels in wild animals throughout the year can improve our understanding of how this pathway responds to different conditions.
