Analysis Of The Correlation Factor About The Predicting Recurrence And Progression In Nonmuscle Invasive Urothelial Bladder Carcinoma

[Object]To confirm the feasibility of the appraisal for the prognosis of patients with urinary bladder cancer in our country by means of the analyzing system of predicting the recurrence and progress factor of nonmuscle invasive bladder carcinoma provided by Richard J etc.[Method]In light of the analysis system of predicting the recurrence and development factor of nonmuscle invasive bladder carcinoma provided by Richard J etc, we analyzed the data of patients with urinary bladder cancer collected by the Urinary Surgery of Chang Hai Hospital. Then carry out the statistical analysis to the data obtained from the system with actual ratio of recurrence and progress, thus appraising whether this system is suitable for domestic prediction of recurrence and progress of patients with bladder cancer.[Results]The data including 481 cases of patients with nonmuscle invasive bladder carcinoma collected by Urinary Surgery of Chang Hai Hospital from Jan. 1992 to Jan. 2002 is divided into four groups according to the scores obtained from six items—number, size, recurrence or not, stage, carcinomatosis in situ or not, class using the system provided by Richard J. The calculation shows that the recurrence ratio in one year in group 0, group 1-4, group 5-9 and group 14-23 is 13.3%,21%,36%,38.8% respectively; the recurrence ratios in five years are 26.5%,44%,59.5%,82.4% respectively. And the data also shows that the actual progress ratio in one year in group 0, group 2-6, group 7-13 and group 14-23 is 0%,1.4%,5.1%,15.6% respectively; the actual progress ratio in five years is 1.1%,6.7%,14.8%,53.1% respectively. After the above-mentioned data is compared with the theoretical results offered by Richard J and analyzed statistically, it concludes that there exists no obvious statistical difference between two results(P>0.05). [Conclusion]The analyzing system of predicting the recurrence and progress factor of nonmuscle invasive bladder carcinoma provided by Richard J etc.is suitable for the analysis for the prognosis of patients with bladder cancer in our country and can assist the doctors of Urinary Surgery to make treatment and follow-up plan reasonably.
