Abstract:
【Objective】 To investigate the effects of radical prostatectomy (RP) or brachytherapy (BT) on the prognosis of patients with high-risk prostate cancer as initial treatment, in order to provide a reference for the selection of clinical treatment options. 【Methods】 The clinical data of 133 191 patients diagnosed with high-risk prostate cancer and treated with RP or BT during 2005 and 2014 were extracted from the SEER database.The 5-year and 10- year cancer-specific survival (CSS) and overall survival (OS) were compared with K-M analysis and univariate and multivariate Cox regression.The clinical data of another 253 patients diagnosed with high-risk prostate cancer in Subei People’s Hospital during 2015 and 2020 were collected, including 153 patients who received RP and 100 patients who received BT.The 5-year biochemical progress-free survival (bPFS) and CSS were compared with K-M analysis. 【Results】 Univariate analysis of SEER data showed that BT was associated with a higher risk of death (HR=1.319, 95%CI: 1.256-1.386, P<0.001); age, marital status and TNM stage were associated with higher risk of death (P<0.001).Multivariate analysis, adjusted for relevant variables, showed that BT did not result in a higher risk of death compared with RP (HR=0.964, 95%CI:0.924-0.996, P=0.808). The OS curve showed that the longer the observed survival time, the better OS of RP as compared to BT (P<0.001); however, the CSS survival curve showed that the longer the observed survival time, the better CSS of BT compared to RP (P<0.001).The single-center data analysis showed no significant difference between BT and RP in the 5-year bPFS (P=0.263) and CSS (P=0.946). 【Conclusion】 For patients with high-risk prostate cancer, there is a significant difference in the prognosis of the two treatments if there is no adjustment of age, marital status, TNM stage and other factors, and the efficacy of RP is better than that of BT, especially in patients with survival more than 10 years.However, there is no statistically significant difference in the prognosis after the possible confounding factors are adjusted.Therefore, the initial treatment choice for these patients should be weighed from multiple perspectives, and patients’ choices must be respected after they are fully informed.
