Source 1: 2007 MP/H Rules
MP/H Rules/Multiple primaries: How many primaries are to be abstracted and what rule applies when a patient has a serous carcinoma of the right ovary treated with neoadjuvant chemotherapy followed by a debulking surgery that also revealed a serous tubal intraepithelial carcinoma of the left fallopian tube? See discussion.
Following the MP/H Rules, rule M11 indicates this would be a separate primary. Should rule M11 be applied in this case because the patient had preoperative chemotherapy and it is unknown whether the patientís ovarian primary initially involved the fallopian tube?
Rule M11 applies. Abstract two primaries for this case based on the information provided.
It could be helpful to know the extent of involvement noted prior to neoadjuvant therapy and debulking surgery.
