All men underwent radical cystectomy and women underwent anterior pelvic exentration. Most patients had postoperative radiation therapy. The log-rank test examined differences in OAS and DFS rates.Results: The medical records of 106 patients were analyzed. The median follow- up from the date of enrollment was 30 months and ranged from 2 to 73 months. For the entire group, three-year OAS rates were 46.9% and DFS rates were 44%. For patients with P2 (tumor invasion into the muscularis propria) the three-year OAS rate was 53%, for P3 (tumor invasion into perivesical fat) it was 45% and 9% for P4 (tumor invasion into adjacent organs, pelvic wall or abdominal wall) The OAS rate was statistically significant in favor of P2 disease (P=0.0041). The three-year DFS rate was 50% for P2, 45% for P3 and 9% for P4 disease (P=0.0125). Administration of post-operative radiotherapy did not result in statistically significant improvement in three-year OAS and DFS rates.Conclusion: Survival rates were statistically significant and higher in patients with P2 and P3 disease compared to P4 disease. Adjuvant radiotherapy did not result in statistically significant survival improvement UR - https://mejc.sums.ac.ir/article_41884.html L1 - https://mejc.sums.ac.ir/article_41884_c33168036cbfb67f5925cdb43fbb6c2b.pdf ER -
