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.

【Objective】 To investigate the relationship between preoperative albumin-to-alkaline phosphatase ratio (AAPR) and postoperative recurrence of localized penile cancer (T1-3N0M0). 【Methods】 Clinical data of patients with limited penile cancer admitted to our hospital during Jan.2012 and Jan.2017 were collected to compare the differences in age, body mass index (BMI), AAPR, hypertension, diabetes mellitus, tumor diameter, postoperative pathological grading and staging between the postoperative recurrence group and the non-recurrence group. 【Results】 The differences in AAPR(P=0.001), WHO/ISUP pathological grading(P=0.018), and pathological stage(P=0.012)between the recurrence and non-recurrence groups were statistically significant. Cox regression results showed that AAPR was an independent risk factor for recurrence (P=0.041). Survival curve results showed that patients in the high and low AAPR groups had an inverse relationship with recurrence-free survival (P=0.028). 【Conclusion】 Preoperative AAPR is an independent risk factor for recurrence after surgery for limited penile cancer and is associated with recurrence-free survival. As AAPR increases, the incidence of recurrence decreases and progression-free survival increases.

Objective To investigate the relationship between preoperative albumin-to-alkaline phosphatase ratio and overall survival (OS) after radical cystectomy of bladder cancer.Methods The clinical date of patients with bladder cancer who underwent radical cystectomy and urinary diversion and confirmed by pathology from Jan 2007 to Dec 2015 were analyzed retrospectively,with 140 cases undergoing laparoscopic surgery and 26 cases undergoing open surgery.There were 148 males and 18 females,aged was 33-85 years,with an ayerage ageof (65.1 ± 9.4) years.There were 55 cases of cutaneous ureterostomy,96 cases of Brick diversior with ileum,and 15 cases of ileal neobladder.The AAPR range 0.03-1.67,with an average 0.62 ± 0.23,and body mass index (BMI) was 16.79-32.65 kg/m2,with an average of (24.00 ± 3.32) kg/m2.There were 33 cases with hydronephrosis and 133 no hydronephrosis,31 cases with hypertension and 135 cases no hypertension,and 14 cases with diabetes and 152 cases no diabetes.Four cases were classified as grade0,65 cases as grade 1,86 cases as grade 2,and 11 cases as grade 3.Based on the preoperative AAPR(0.62 ±0.23),they were divided into three groups,with 55 cases in the low AAPR (0.42 ± 0.09) group,55 cases in the middle AAPR (0.58 ± 0.05) group,and 56 cases in the high AAPR (0.86 ± 0.21)group.Cox proportional hazards regression methodology were used to evaluate the relationship between preoperative AAPR and overall survival.Survival analysis was conducted using the Kaplan-Meier method and compared with the log-rank test.Results 166 patients were followed up for 1-144 months,with a median of 63 months,and 71 cases died and 95 survived.The median serum AAPR level in all cases was 0.59 (range 0.03-1.67).Results of univariate Cox regression model revealed that AAPR(HR =0.09,95％ CI 0.022-0.391,P =0.001),high AAPR (HR=0.40,95％CI0.216-0.742,P=0.003),age (HR =2.42,95％ CI 1.294-4.531,P =0.006),tumor size (HR =2.11,95％ CI 1.112-4.014,P =0.023),pT3 stage (HR=8.93,95％CI3.173-25.114,P＜0.001),pT4 stnge(HR =10.39,95％ CI 3.110-34.707,P ＜0.001),pN1 stage(HR =2.80,95％ CI 1.422-5.531,P =0.003),pN3 stage (HR =17.06,95％ CI2.192-132.863,P =0.007),pathological grade (HR =0.30,95％ CI 0.113-0.817,P =0.019),hydronephrosis (HR =2.36,95 ％ CI 1.406-3.939,P =0.001),adjuvant chemotherapy (HR =2.66,95％ CI 1.674-4.247,P ＜ 0.001)were associated with OS.Compared with patients in the lowest of AAPR,the risk for death in the highest AAPR group decreased about 59％ (HR =0.406,95％ CI 0.200-0.822,P =0.012)after adjustment for age,BMI,tumor size,number of tumor,T category,N category,pathological grade,hydronephrosis,ASA level,adjuvant chemotherapy in multiple Cox regression models.Each unit increase in the AAPR was associated with about 80％ decreased risk of death (HR =0.199,95％ CI 0.051-0.779,P =0.020) after adjusting for the confounding variables.After adjusting for age,BMI,tumor size,number of tumor,T category,N category,pathological grade,hydronephrosis,ASA level,adjuvant chemotherapy,the curve fitting results showed that with the increase of AAPR,the risk of death decreased and the overall survival prolonged.Consistent with the linear trend test results,the relationship between AAPR and OS is linear.Conclusions AAPR was associated with overall survival of patients who underwent radical cystectomy of bladder cancer.
Résumé
PURPOSE: We first analyzed the prognostic power of albumin-to-alkaline phosphatase ratio (AAPR) before radical radiotherapy (RT) in non-metastatic nasopharyngeal carcinoma (NPC) patients. MATERIALS AND METHODS: The records of 170 patients with biopsy-proven, non-metastatic NPC treated by radical RT between 1998 and 2016 at our institution were retrospectively reviewed. Median follow-up duration was 50.6 months. All patients received intensity-modulated RT and cisplatin based chemotherapy before, during, or after RT. The major treatment of patients was based on concurrent chemoradiotherapy (92.4%). The AAPR was calculated by the last value of both albumin and alkaline phosphatase within 1 month immediately preceding RT. The optimal cut-off level of AAPR was determined by using Cutoff Finder, a web-based system. Propensity score matching (PSM) analysis was performed. RESULTS: The optimal cut-off level of AAPR was 0.4876. After PSM analysis of whole cohort, an AAPR was not related to survival outcomes. In PSM analysis for patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC), an AAPR ≥ 0.4876 was related to better overall survival (OS), progression-free survival (PFS), and locoregional relapse–free survival (LRRFS) (OS: hazard ratio [HR], 0.341; 95% confidence interval [CI], 0.144 to 0.805; p=0.014; PFS: HR, 0.416; 95% CI, 0.189 to 0.914; p=0.029; and LRRFS: HR, 0.243; 95% CI, 0.077 to 0.769; p=0.016, respectively). CONCLUSION: The AAPR, inexpensive and readily derived from a routine blood test, could be an independent prognostic factor for patients with LA-NPC. And it might help physicians determine treatment plans by identifying the patient's current status. Future prospective clinical trials to validate its prognostic value are needed.
