MP/H Rules/Behavior--Breast: How are behavior and histology coded when the pathology report final diagnosis is "ductal carcinoma in situ and lobular carcinoma in situ" if the microscopic examination section of the same pathology report states there are "foci suspicious for microinvasive carcinoma"? See Discussion.
MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion.
MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries?
MP/H Rules--Melanoma: How many primaries are represented if subsequent to a diagnosis of malignant melanoma of skin of left thorax in April 2006, a metastatic melanoma is discovered in the soft tissue of the abdomen and in the skin and subcutaneous tissue of the groin in late 2007? See Discussion.
MP/H Rules--Lung: Why the term "nodule" is not included as an equivalent term along with tumor, mass, lesion and neoplasm in the 2007 lung multiple primary rules?
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
