RADICALS - Radiotherapy and Androgen Deprivation In Combination After Local Surgery

NCT00541047 ↗

RandomizedFactorialOpen-labelTreatment

Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Androgens can cause the growth of prostate cancer cells. Androgen deprivation therapy, such as goserelin, leuprolide, or bicalutamide, may lessen the amount of androgens made by the body. Giving radiation therapy together with androgen deprivation therapy may kill more prostate cancer cells. PURPOSE: This randomized phase III trial is studying how well giving radiation therapy together with androgen deprivation therapy works in treating patients who have undergone surgery for prostate cancer.

Outcome

Mixed primary results

paper With 80 distant metastasis events, 10-year FFDM was 93% for Adjuvant-RT and 90% for Salvage-RT: HR=0.68 [95% confidence interval (CI) 0.43-1.07, P=0.095]. PMID 38583574 ↗

paper Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. PMID 38763154 ↗

paper Compared with adding 6 months of ADT, adding 24 months of ADT improved metastasis-free survival in people receiving postoperative radiotherapy. PMID 38763153 ↗
