Comparative efficacy of radical prostatectomy and radiotherapy in the treatment of high-risk prostate cancer.

Background: Both radical prostatectomy and radiation therapy are effective in controlling the condition of patients with hormone-resistant prostate cancer (HRPCa). However, there is limited research on the prognosis and quality of life of HRPCa patients after different treatment modalities.

Objective: To explore the efficacy of radical prostatectomy (RP) and radiotherapy (RT), when treating high-risk prostate cancer (HRPCa).

Methods: Overall 103 HRPCa patients were included and were divided into RP group and RT group according to different treatment methods. The propensity score matching method (PSM) was used to balance the baseline data of the two groups and match 34 patients in each group. The prognosis, quality of life, and basic efficacy of patients were compared.

Results: After intervention, the disease-free survival rate of the RT group was higher than that of the RP group (79.41% vs. 55.88%, p= 0.038). Quality of life scores between the two treatment methods had no difference before intervention (p> 0.05), but higher in RT group than that of the RP group after intervention (p< 0.05). After treatment, there was no statistically significant difference in total effective rate of treatment between two groups (44.12% vs. 58.82%, p> 0.05), but the disease control rate was significantly higher in RT group (94.12% vs. 76.47%, p= 0.040).

Conclusion: Radical radiotherapy is effective in the clinical treatment of HRPCa patients, with a higher disease-free survival rate and improved quality of life after treatment, and is worth promoting.
