Question:

Multiple Primaries (Pre-2007)--Kidney/Bladder/Renal Pelvis: Would transitional cell carcinoma of the left renal pelvis, diagnosed two years after a diagnosis of invasive bladder cancer, be a second primary when the discharge is "recurrent transitional cell carcinoma, left kidney"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

This is an example of the term "recurrent" being used loosely to refer to another primary in the urinary tract. It is highly unlikely that a bladder tumor would metastasize to the kidney. Much more likely is the field defect or regional breakdown of the urothelial tissue that lines the tract from the renal pelvis to the urethra. Furthermore, bladder tumors don't spread retrograde to the kidney. Code as two 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.
