2010 SEER Manual. Appendix C
Question:
MP/H Rules/Multiple primaries--Bladder: How many primaries are to be abstracted and how are the histologies coded when a bladder resection demonstrates tumor with invasive small cell neuroendocrine carcinoma [8041/3], high grade papillary urothelial carcinoma in situ [8130/2], adenocarcinoma in situ [8140/2], and multifocal flat urothelial carcinoma in situ? See Discussion.
Discussion:
Are the areas of in situ tumor to be ignored or would MP/H Rule M9 apply?
Answer:
Ignore the in situ histologies. This is a single primary. Code the histology to invasive small cell neuroendocrine carcinoma [8041/3].
