MP/H/Multiple primaries--Urinary: In Aug 2008 Patient was diagnosed with Noninvasive Bladder Cancer. In Oct 2013 Patient was diagnosed with Transitional Cell Carcinoma of Right Ureter involving lamina propria, Noninvasive Transitional Cell Carcinoma Left Ureter and Invasive Transitional Cell Carcinoma of Prostatic Urethra. Is this a new primary and what is the primary site?
MP/H/Multiple Primaries--Urinary: Is this one primary with a C689 primary code and morphology 8130/3? Or is this 2 primaries: 1. C679 8130/3 and 2.C680 8120/2. See discussion.
MPH Rules/Multiple primaries--Melanoma: Does MP/H Rule M7 (diagnosed more than 60 days apart) apply to invasive melanoma cases with margins positive for in situ melanoma, or are these further excision of the original diagnosis and the same primary, even when it appears treatment was complete after the initial excision? See Discussion.
Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion.
Multiple Primaries (Pre-2007)--Breast: For a patient with a remote history of lobular breast carcinoma, would a new diagnosis of lobular breast carcinoma with DCIS be a new primary, even though the physician designates it as recurrent? See Description.
Multiple Primaries (Pre-2007)--Breast: When simultaneously diagnosed breast tumors of the same histology in the same breast are stated by the pathologist and/or clinician to be more than one primary, should these be reported as multiple primaries? See discussion.
Multiple Primaries (Pre-2007)--Breast: When two breast tumors with two different histologies, such as duct and mucinous are diagnosed in the same breast at the same time, are they reportable as two primaries? See discussion.
Multiple Primaries (Pre-2007)--Melanoma: Many melanoma patients have multiple occurrences over time that are not called recurrent and often are even in the same skin subsite, some in situ only and others alternating between in situ and invasive. Should these multiple occurrences really be new primaries?
Multiple Primaries (Pre-2007)--Ovary/Endometrium: Is endometrioid adenocarcinoma occuring simultaneously in the left ovary and the endometrium one primary or two? See discussion.
Multiple Primaries (Pre-2007)--Ovary: Are mucinous cystic tumors of low malignant potential diagnosed in the left ovary in 12/2000 and in the right ovary in 7/2001 reportable as two primaries? See discussion.
