Question:
MP/H Rules/Multiple Primaries--Bladder/Renal Pelvis: Is a non-invasive papillary transitional cell carcinoma of the bladder diagnosed one year after the occurrence of an invasive papillary transitional cell carcinoma of the renal pelvis reported as one or two primaries?
Discussion:
Answer:
For cases diagnosed 2007 or later:
This is a single primary with renal pelvis as primary site.
Use the 2007 MP/H rules to determine if the 2007 diagnosis is a new primary. Use the Urinary rules, multiple tumors module. Start with rule M3. Follow the rules down to Rule M8 and stop. This is an example of implantation effect.
