Urothelial carcinoma of the bladder with transmural and direct prostatic stromal invasion: does extent of stromal invasion significantly impact patient outcome?

Urothelial carcinoma of the bladder with transmural and direct prostatic stromal invasion: does extent of stromal invasion significantly impact patient outcome?

Yes and No: Survival by stage which correlates with invasiveness shows survival drop as stage increases. However, the staging system is going to calll 1mm into the prostate a t4a and 25mm into the prostate as the same. So, it is hard to tell that the exactly invasion depth into the prostate is proven to correlate with outcome. In general...The more aggressive it is, the worse patients do. ...Read more

Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?

Marker not prognosis: CK7 and calretinin are used to verify that the tumor is mesothelial in origin (versus adenocarcinoma of the lung). It does not provide information about prognosis. Factors associated with pleural mesothelioma prognosis include: functional status, blood counts, histology (epithelial best vs fibrosarcomatous poorest), and tumor size (degree of involvement of pleural cavity).
