Updates to Breast and Urinary MPH 2018 modules #42

Closed bekeles closed 5 years ago

Breast Changes Rule M13: Abstract a single primary when synchronous, separate/non-contiguous tumors are on the same row… Behavior restriction removed. Tumors do not need to be the same behavior.

NEW RULE: Rule M9: Abstract multiple primaries when the diagnosis is Paget disease with synchronous/simultaneous underlying tumor which is NOT duct.

Rule M10: Abstract a single primary when synchronous/simultaneous multiple tumors are carcinoma NST/duct and lobular. Behavior restriction removed. Histologies do not need to be the same behavior.

Urinary Changes Rules were added, deleted and moved- so check numbering.

Rule M6: Abstract multiple primaries when an invasive tumor occurs more than 60 days after an in situ tumor. Moved up in hierarchy (formerly M17)

Rule M7: Abstract a single primary when the patient has multiple occurrences of /2 urothelial carcinoma in the bladder. Clarified that any combination of 8120/2 and 8130/2 in the bladder is a single primary

Rule M8: Abstract multiple primaries when the patient has micropapillary urothelial carcinoma 8131/3 of the bladder AND a urothelial carcinoma 8120/3 (including papillary 8130/3) of the bladder. Moved up in hierarchy (formerly Rule M12) 8120/3 added to the rule Removed non-synchronous tumors requirement

Rule M9: Abstract a single primary when the patient has multiple invasive urothelial cell carcinomas in the bladder. Clarified that an occurrence of micropapillary and an occurrence of urothelial carcinoma would be multiple primaries

Rule M11: Abstract a single primary when there are urothelial carcinomas in multiple urinary organs. "Synchronous" removed- timing is now irrelevant

Rule M13 (Former): Abstract multiple primaries when the original tumor and subsequent tumor occur in different urinary sites. Rule deleted

NEW RULE: Rule M14: Abstract multiple primaries when the ICD-O site code differs at the second (CXxx) and/or third (CxXx) character.

Rule M15: Abstract a single primary when synchronous, separate/non-contiguous tumors are on the same row in Table 2 in the Equivalent Terms and Definitions. Behavior restriction removed; behavior is now irrelevant

The changes are made to the main 2018 rules branch. I am closing this,
