Abstract:
Objective To explore the impact of different anesthesia methods and anesthesia-related factors in initial bladder cancer patients with partial cystectomy, and to provide a reference for clinical anesthesia choice and the questions that should be concerned. Methods Ambispective cohort study was performed in consecutive case of illness with initial occurrence bladder cancer patients treatedwith partial cystectomy from 2009 to 2012. A historical cohort was from January 5, 2009 to January 4, 2011. A prospective cohort was from January 5, 2011 to December 31, 2011. Follow-up was terminated in December 31, 2012. All cases were followed up to one full year after surgery. The 402 cases who were diagnosed of initial occurrence bladder cancer and partial cystectomy patients, according to different anesthesia method, were divided into general anesthesia group and intraspinal anesthesia group. Postoperative recurrence was determined within 1 year of follow-up. Multivariate analysis was carried out based on univariate analysis to analyze the causal connection factors for one year recurrence in initial occurrence bladder cancer patients with partial cystectomy. Variables included gender, age, blood type, smoking history, drinking history , number of tumors, tumor size, pathologic TNM stage, anesthesia method, duration of anesthesia, postoperative visual analog scale (VAS) score at 12 h, tumor-associated factor Ki67, P53, CK20, VEGF (whether two or more positive). Tumor recurrence was considered the dependent variable (outcome). Univariate analysis used χ2 or rank sum test, and multivariate analysis used Logistic regression model fitting analysis and the maximum likelihood method. SPSS 16.0 software package was used for data analysis and processing. Results Four hundred and two patients were followed up and got a result of 396 cases (98.51％). Two hundred and eleven cases showed recurrence within one year (53.28％). Univariate analysis showed that age, smoking history, drinking history, duration of anesthesia, pathologic stage, postoperative VAS scores at 12 h less than 3 scores, blood type, tumor-associated factor Ki67, P53, CK20, VEGF (two or more positive) were associated with one year recurrence in initial occurrence bladder cancer patients (P < 0.01) with partial cystectomy, while the difference of two anesthesia methods was not shown (P>0.05). Multivariate Logistic regression model analysis showed that the following factors were associated with postoperative recurrence within a year in initial occurrence bladder cancer patients with partial cystectomy: age (RR = 0.371, 95％ CI 0.183-0.752), drinking history (RR=0.348, 95％CI 0.161-0.752), postoperative VAS scores at 12 h less than 3 scores (RR=0.023, 95％CI 0.011-0.050), duration of anesthesia (RR=3.042, 95％CI 1.495-6.192), and tumor-associated factor Ki67, P53, CK20, VEGF of two or more positive(RR=8.676, 95％CI 4.018-18.733). Among these, duration of anesthesia and tumor-associated factors Ki67, P53, CK20, VEGF of two or more positive were risk factors, and drinking history, age, and postoperative VAS scores at 12 h less than 3 scores were protection factors. Conclusions The impact of general anesthesia and intraspinal anesthesia on one year recurrence in initial occurrence bladder cancer patients with partial cystectomy is not statistically significant. Duration of anesthesia depends on the part of the surgical time which is associated with the postoperative recurrence within a year. Postoperative analgesic perfect (VAS score at 12 h less than 3 scores) is the protective factor. Age and drinking history are also the protective factors for one year recurrence in initial occurrence bladder cancer patients of partial cystectomy.
