Summary
This study analyzed 15-year outcomes for prostate cancer patients treated with external radiation and radioactive gold grain (Au198) implantation. Results showed moderate locoregional control and survival rates, suggesting potential improvements with patient selection and radiation dosing.
Area of Science:
- Oncology
- Radiation Oncology
- Medical Physics
Context:
- Prostate adenocarcinoma treatment outcomes require long-term evaluation.
- Combined external beam radiotherapy and brachytherapy represent a treatment modality.
- Assessing 15-year survival and disease control is crucial for treatment efficacy.
Purpose:
- To evaluate the 15-year results of combined external irradiation and radioactive gold grain (Au198) implantation for prostate adenocarcinoma.
- To analyze therapeutic perspectives based on long-term outcomes.
Summary:
- A cohort of 23 patients with localized prostate carcinoma (Stage B and C) received combined therapy.
- Mean follow-up was 90.96 months, with Au198 implantation followed by external irradiation (Co-60 or 18-MV photons).
- 15-year locoregional control was 61%, disease-free survival 38%, and overall survival 25%. Stage B control was 61%, Stage C 83%.
Impact:
- The study suggests that combined therapy yielded slightly lower rates than radical external radiation alone.
- Findings indicate that suboptimal patient selection and radiation dose may have influenced outcomes.
- This research informs future treatment strategies for prostate cancer, emphasizing dose optimization and patient stratification.
