Question:

MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?

Discussion:

Answer:

For cases diagnosed 2007 or later:

No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
