Question:

Multiple Primaries (Pre-2007)--Head & Neck: How many primaries are represented when a1998 invasive squamous cell carcinoma of the true vocal cord is followed by a 1999 diagnosis of in situ squamous cell carcinoma of the true vocal cord (called "recurrent" by the clinician), and in 2001 there is another invasive squamous cell carcinoma of the true vocal cord (no statement of recurrence)? Would your answer be any different if no statement of "recurrent" had been made in 1999?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code this case as two primaries, an invasive true vocal cord primary in 1998 and another invasive true vocal cord primary in 2001.

If there had been no statement of recurrence for the 1999 in situ diagnosis and the 1999 diagnosis was more than two months following the 1998 diagnosis, this case would be coded as three primaries.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
