Inquiry Details

#1: 2007 MP/H Rules. Equivalent terms and definitions
#2: WHO Class Male Genital Tumors
Question:
MP/H Rules/Multiple primaries--Prostate: Is duct carcinoma of the prostate the same as an adeno/acinar carcinoma of the prostate? Specifically, does rule M3 apply when there is an adenocarcinoma of the prostate followed by a duct carcinoma of the prostate or a duct carcinoma followed by adenocarcinoma?
Discussion:
Answer:
Rule M3 does not apply to adenocarcinoma followed by duct carcinoma of the prostate or vice versa. Rule M3 pertains to cases of adenocarcinoma and acinar carcinoma. These two terms, adenocarcinoma and acinar carcinoma, are equivalent for the purpose of applying the MP/H rules to prostate cases. See page 77 of the Other Sites Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
