Abstract
- Introduction Urothelial carcinoma (UC) is the most common bladder cancer. The most censorious pathological aspect of UC is deep muscle invasion and tumor grade. In this study, we assessed the prognostic implications of tumor grade and deep muscle invasion in UC. Methods It was a retrospective cross-sectional study conducted at the Department of Histopathology, Liaquat National Hospital, from July to December 2019. The data were collected over five years from January 2014 till December 2018. Records from archives of the anatomic pathology were searched, clinical characteristics were recorded, and histopathological slides were reviewed. Histological parameters, including tumor grade and muscle invasion, were evaluated. Records of patient follow-up were assessed by reviewing clinical records. Recurrence of UC and overall survival was also recorded. Multivariate binary logistic regression was applied for variables that were significant on univariate logistic regression. Survival analysis was performed using the Kaplan-Meier method. Results The mean age of the patients was 63.39 ± 14.1 years. More than half (53%) cases were of low-grade papillary UC. Disease recurrence was observed in 53 (39.1%) patients, whereas the mortality rate was 16.6%. In our study, 49 (32.5%) patients were found to have deep muscle invasion. By multivariate analysis, we found that the deep muscle invasion was significantly associated with male gender and grade. In addition, a significant association of high-tumor grade with survival status of the patients was noted. Conclusions A high proportion of UC cases in our study were found to have deep muscle invasion and high-tumor grade. Moreover, a significant association of deep muscle invasion with tumor grade and an association of tumor grade with survival signify the prognostic value of these factors in UC.
