Question:

Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?

Discussion:

Answer:

One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
