SEER Inquiry System - Question 20140030 Details

MP/H Rules/Multiple primaries--Bladder: Is this a single primary or multiple primaries? Transurethral resection of the bladder identifies two bladder tumors. Pathology states one is high grade papillary carcinoma (8130/3) and the other is lymphoepithelioma-like urothelial carcinoma (8082/3). Lymphoepithelioma-like is listed as a urothelial type in Table 1 but rule M6 does not include it in the list of histologies and we are not told to refer to Table 1. M8 refers to Table 1 but does not include multiple bladder tumors (C67_). Specify which rule would apply and why.
