More than 90% of the bladder cancers are transitional cell carcinoma types and 80% of superficial tumors recur after treatment. In order to determine the recurrence rate and prognostic factors of superficial bladder cancer (SBC), this study was conducted. </span><br> <strong><span style="font-size:18px;"><span style="color:#ffffff;"><span style="background-color:#16a085;">Materials and Methods:</span></span></span></strong><span style="font-size:16px;"> The information of this historical cohort study was obtained from files of the patients admitted to Shiraz Shahid Faghihi Hospital from 1998-2001. The 76 cases of bladder cancer were diagnosed for the first time as new cases. Variables included in the analysis were age, sex, residential place, job, tumor pathologic grade and stage, BCG therapy, date of diagnosis and time of recurrence. All data were analysed by SPSS-10 software. For assessing prognostic factors of recurrence, the Cox regression multivariate analysis was used and the survival curves were analysed by Kaplan Mayer procedure. </span><br> <strong><span style="font-size:18px;"><span style="color:#ffffff;"><span style="background-color:#16a085;">Results:</span></span></span></strong><span style="font-size:16px;"> Out of 76 cases of bladder cancer, 72 cases (94.74%) had transitional cell carcinoma and the ratio of male to female was 4.5:1. Twenty-seven (45%) of all SBC cases experienced recurrence. The mean length of follow-up was 14.8 months. In the Kaplan-Mayer survival analysis, the mean length of the recurrence-free period with 95% confidence interval was 24.2 months(18.3- 30.1). For every 10 years of age, the probability of SBC recurrence will increase about 0.5 fold. Also, the probability of recurrence in grade II and III patients was 4.5 and 11 fold higher than in grade I patients, respectively. </span><br> <span style="color:#ffffff;"><span style="font-size:18px;"><strong><span style="background-color:#16a085;">Conclusion:</span></strong></span></span><span style="font-size:16px;"> Considering the differences between our results and others, we suggest further regional studies to be conducted in this context in order to predict precisely the patient&#39;s status.</span></span></td> </tr> <tr> <td colspan="2" style="text-align: justify;"><span style="font-family:Times New Roman;"><span style="font-size:16px;">&nbsp;</span></span></td> </tr> </tbody> </table> <div style="text-align: justify;"></div> BLADDER CANCER, RECURRENCE RATE, PROGNOSTIC FACTORS 1 9 http://journal.zums.ac.ir/browse.php?a_code=A-10-1-29&slc_lang=fa&sid=1 Ejaz Ahmadi اعجاز احمد 5200319475328460070035 5200319475328460070035 Yes Omid Ghasemkhani امید قاسم خانی 5200319475328460070036 5200319475328460070036 No Parisa Dastori پریسا دستوری 5200319475328460070037 5200319475328460070037 No
