Inquiry Details
References:
2007 MP/H Rules
Question:
MP/H/Multiple Primaries--Urinary: Is this one primary with a C689 primary code and morphology 8130/3? Or is this 2 primaries: 1. C679 8130/3 and 2.C680 8120/2. See discussion.
Discussion:
Urinary: Transitional Cell Carcinoma and open prostatectomy: Path from Bladder: Papillary and solid transitional cell carcinoma of bladder - grade II and III Stage A.
Path from prostatectomy: The prostatic tissue samples shows areas of urothelia carcinoma in situ - related to the tumor present in the bladder.
Conclusion: Prostatectomy showing foci of transitional cell carcinoma in situ of prostatic urethra.
Answer:
Abstract a single primary, C679 8130/3. Rules M2 and H4 apply. Transitional cell/urothelial carcinoma in the prostatic urethra is likely an extension from the known bladder TCC in this case, not a separate primary. See prostatic urethra on page 63 in the Urinary Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
