Question:
MP/H Rules/Multiple primaries--Urinary: Are diagnoses in bladder, ureter, renal pelvis, and other urinary made prior to 2007 used in determining multiple primaries? See Discussion.
Discussion:
Per the General Information for MPH, Rule #3, the rules are effective for cases diagnosed January 1, 2007 and after. Do not use these rules to abstract cases diagnosed prior to January 1, 2007.
Example: Is a 2006 diagnosis of a renal pelvis primary with the histology 8130/3 and a 2007 diagnosis of a bladder primary with histology 8130/3 "multiple tumors" or is the bladder tumor a new primary because it is a single tumor at the time of diagnosis in 2007?
Answer:
For cases diagnosed 2007 or later:
Use the 2007 MP/H rules for urinary sites to assess tumors diagnosed in 2007 or later.
For the example above, use the 2007 rules to determine whether or not the bladder tumor diagnosed in 2007 is a new primary. Use the Multiple Tumors module when comparing a 2007 or later diagnosis to an earlier diagnosis. Start with rule M3. Stop at rule M8. The 2007 bladder urothelial tumor is not a new primary since there is an existing 2006 renal pelvis urothelial primary.
