Summary
Brief summary (as posted)
This study aims to evaluate the efficacy of adjuvant docetaxel chemotherapy following radical radiotherapy in patients with localized high-grade prostate cancer. Eligible participants include those diagnosed with prostate cancer confirmed by biopsy or surgical pathology, with a Gleason score of 9-10 or containing a Gleason 5 component, and no evidence of distant metastasis. Patients will be divided into two groups: the standard treatment group receiving only radical treatment (radiotherapy or surgery), and the standard treatment plus chemotherapy group, receiving four to six cycles of docetaxel chemotherapy after standard treatment. The primary endpoint is Failure-Free Survival (FFS), with secondary endpoints including Biochemical Relapse-Free Survival (BRFS), Metastasis-Free Survival (MFS), Overall Survival (OS), and assessment of adverse events The study aims to better understand the impact of adjuvant chemotherapy on the prognosis of patients with high-risk prostate cancer and determine whether it improves survival outcomes.

Arms (2)
- label
- Standard Treatment Plus Chemotherapy Group
- description
- This group will receive the standard radical treatment as in Arm 2, followed by adjuvant chemotherapy with docetaxel. Chemotherapy will start 4-8 weeks after the completion of radiotherapy. The chemotherapy regimen will consist of docetaxel 75 mg/m² administered intravenously on Day 1, repeated every 21 days for a total of 4-6 cycles. In cases of significant neuroendocrine differentiation and if well-tolerated, a combination of docetaxel and carboplatin (docetaxel 75 mg/m² and carboplatin AUC 4-6) will be used. Pre-treatment with dexamethasone will be administered to reduce potential side effects.

- Standard Treatment Group
- description
- This group will receive the standard radical treatment for high-grade localized prostate cancer. Patients will undergo definitive or post operative radiotherapy. Endocrine therapy will be provided for high-risk patients as per NCCN guidelines, with a duration of 2 to 3 years with definitive radiotherapy . For postoperative patients, endocrine therapy will be given for salvage setting.
