Abstract:
Objective:To investigate the influencing factors of survival benefit of patients after radical cystectomy and its correlation with preoperative albumin-to-alkaline phosphatase ratio (AAPR).Methods:The clinical data of 116 patients after radical cystectomy were retrospectively analyzed from January 2011 to January 2020 in Handan First Hospital. The influencing factors of survival benefit of patients after radical cystectomy were analyzed and the correlation between preoperative AAPR and overall survival time were evaluated. Kaplan-Meier method was used for survival analysis, and Log-rank test was used for comparison between groups. Cox proportional regression model was used to analyze the influencing factors of survival and prognosis and the correlation with preoperative AAPR. Trend Chi-square test was used to evaluate the level of preoperative AAPR.Results:Univariate Cox regression analysis showed that age, tumor diameter, pT stage, pN stage, histopathological grade, hydronephrosis, postoperative adjuvant chemotherapy and preoperative AAPR level were related to the overall survival time of patients after radical cystectomy( P<0.05). Multivariate Cox regression analysis showed that in calibration model Ⅰ and Ⅱ, the risk of death in high AAPR group was 0.351 and 0.433 times higher than low AAPR group( P<0.05). The risk of death decreased to 85.9% and 84.6% for every one unit increase of preoperative AAPR. The overall survival time of patients with high AARP level were significantly longer than patients with low and medium AARP level( P<0.05). Conclusion:The survival benefit of patients after radical cystectomy was independently related to the preoperative AAPR level; the higher the preoperative AAPR level, the longer the overall survival time.
