Radiotherapy should be recommended for patients with metastatic castration-sensitive Prostate Cancer, summarized by Gustavo Viani

Gustavo Viani, Associate Professor at Hospital das Clínicas, shared an article by Alberto Bossi on LinkedIn:

” Radiotherapy should be recommended for with metastatic castration-sensitive prostate cancer, independently of their metastatic burden.

Objective:
• To evaluate the efficacy and safety of adding to standard of care in with de novo metastatic castration-sensitive prostate cancer (mCSPC), focusing on radiographic progression-free survival (rPFS) and overall survival (OS)

Methods:
• Study Design: Open-label, randomised, phase 3 trial (PEACE-1) with a 2 × 2 factorial
• Participants:
• aged ≥18 years with de novo mCSPC.
• Confirmed by bone scan, CT, or MRI; Eastern Cooperative Oncology Group performance status of 0–1
• Interventions:
• 4 groups:
1. Standard of care (androgen-deprivation therapy with or without docetaxel).
2. Standard of care + abiraterone (oral 1000 mg daily with prednisone).
3. Standard of care + (74 Gy in 37 fractions).
4. Standard of care + abiraterone.
• Endpoints:
• : Radiographic progression-free survival and overall survival.
• Analysis: Intention-to-treat for low-volume disease and overall population.

Results:
• : 1173 enrolled;
• Fu: Median 6.0 years (IQR 5.1–7.0)

Key Findings:
• Adding rPFS in with low-volume disease treated with abiraterone (median 7.5 years vs 4.4 years; HR 0.65; p=0.019).
• No benefit in low-volume not treated with abiraterone (median 2.6 years vs 3.0 years; HR 1.08; p=0.61).
• No significant difference in OS for low-volume disease with (median 7.5 years vs 6.9 years; HR 0.98; p=0.86).
• Adverse events (grade ≥3) 56.1% of without 58.8% of with.”
