Question:
Multiple Primaries/Histology Rules/Multiple primaries--Kidney, renal pelvis: Are tumors diagnosed more than three years apart multiple primaries according to Rule M7 in a case with metastasis? See Discussion.
Discussion:
5/27/02 Transurethral resection of bladder tumor (TURBT)--papillary transitional cell carcinoma, +lamina propria, no muscle invasion. All urine cytologies in 2011 and 2012 (only follow up received) show no malignancy. 3/11/15 Lung fine needle aspirate--poorly differentiated carcinoma consistent with urothelial carcinoma. 4/30/15 Renal pelvis biopsy--low grade papillary urothelial carcinoma, no lamina propria invasion, no muscularis propria invasion.
Answer:
Rule M7 applies. Abstract the bladder diagnosis and the renal pelvis diagnosis as separate primaries.
The lung diagnosis is metastatic. The MP/H rules do not apply to metastatic tumors.
