MP/H Rules/Recurrence--Ovary: How many primaries are accessioned if a patient was diagnosed with ovarian serous carcinoma four years ago and currently has sacral and pelvic masses positive for serous carcinoma on biopsy? Should this be disease progression or a new primary? See Discussion.

MP/H Rules/Recurrence--Breast: If the pathologist and oncologist call a 2007 lobular carcinoma that appears in a skin nodule of a mastectomy scar a recurrence of a patient's 1975 primary breast duct carcinoma, should we abstract this as a new primary? See Discussion.

MP/H Rules/Primary site--Kidney, Renal Pelvis: Should the primary site be changed to C689 [Urinary system, NOS] for a primary renal pelvis tumor after additional tumors are found months later in different urinary sites (e.g., bladder or ureter) and the MP/H Rules indicate these are all the same primary? See Discussion.

MP/H Rules/Multiple primaries: Please clarify how rule M10 for Other Sites was developed and how a "recurrence" of the tumor after one year was determined to be a new primary? See Discussion.

MP/H Rules/Multiple Primaries: Is this counted as one or two primaries?

Patient is diagnosed with SCC esophageal cancer. Work-up reveals a lung nodule. Lung FNA (cytology) is read by the pathologist as SCC, favor metastatic esophageal SCC. However, the managing physicians are treating the patient as two separate primaries.

MP/H Rules/Multiple primaries: How many primaries are to be abstracted when a patient was initially diagnosed with epithelioid sarcoma in 2003, underwent multiple resections, radiation, and ultimately partial amputation of the limb in 2010, each with margins positive for residual epithelioid sarcoma? See Discussion.

MP/H Rules/Multiple primaries/Histology: What histology and how many primaries are coded for a mixed germ cell tumor with a somatic type malignancy (rhabdomysarcoma) if the patient was diagnosed with seminoma of the testis in 2009 followed by a 2015 metastatic germ cell tumor in a retroperitoneal lymph node, stated to be a recurrence of the testicular cancer? See Discussion.

MP/H Rules/Multiple primaries/Histology--Rectum: How many primaries does this person have and what is the correct histology? See discussion.

MP/H Rules/Multiple primaries/Cancer-directed treatment--Lung: Is a 2008 occurrence of non-small cell carcinoma in the left lower lobe following a 1998 occurrence of the same histology in the left lung to be counted as a new primary if the 1998 primary was treated with chemotherapy and/or radiation but not surgery? See Discussion.

MP/H Rules/Multiple primaries--Urinary: Is a renal pelvis diagnosed 5/2016 a separate primary when the first invasive bladder was 12/2011? Per rule M7, the 5/2016 renal pelvis is more than 3 years later. Does Multiple Primary/Histology (MP/H) rule M7 refer back to the original diagnosis date or to the last occurrence? See Discussion.
