Question:
Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
Discussion:
Answer:
If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries.
The primary site is probably ovarian, unless:
--Ovaries have been previously removed
--Ovaries are not involved (negative)
--Ovaries have no area of involvement greater than 5mm.
Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary.
Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary.
