Question:

Multiple Primaries (Pre-2007)/EOD-Extension--Bladder/Prostatic Urethra: When noninvasive papillary transitional carcinoma of the bladder and invasive papillary transitional cell carcinoma of the prostatic urethra are diagnosed at the same time, and staged by the pathologist as two primaries, should they reported as two primaries? If reportable as a single primary what site code should be used?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

No. This is one primary. Mucosal spread of noninvasive cancer from a hollow organ (bladder) into another hollow organ (prostatic urethra) is coded as a single primary. The prostatic urethra is seldom a primary site. The cancer usually starts in the bladder and spreads to the prostatic urethra via the mucosa. In this case the cancer in the prostatic urethra became invasive. Code primary site as bladder, NOS [C67.9].

For cases diagnosed 1998-2003: Code EOD Extension using the invasive information (prostatic urethra).

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.
