Scenario: 9-18-2018 TURBT : noninvasive papillary urothelial carcinoma with adjacent urothelial carcinoma in situ
Question: How would you assign the clinical T category?
- CAnswer Forum Post Tis is a higher T category than Ta, therefore this should always be assigned Tis. http://cancerbulletin.facs.org/forums/forum/ajcc-tnm-staging-8th-edition/urinary-tract/urinary-bladder-chapter-62/85952-prognostic-stage-group-for-ta-tis
- AJCC 8th Edition Chapter 62 [Under Prognostic Factors) Concurrent Urothelial Carcinoma in situ: The presence of urothelial carcinoma in situ has been associated with the presence of multifocal disease in the urinary tract and increased risk of invasive disease. Urothelial carcinoma in situ that occurs in association with high-grade papillary urothelial carcinoma should be reported and has been shown to be a negative prognostic indicator. In such cases, care must be taken to distinguish the “shoulder” (lateral extension) of a high-grade papillary carcinoma from a separate focus of urothelial carcinoma in situ. 21–23AJCC Level of Evidence: II
