LOINC long common name : Synchronous tumor site Cancer;
LOINC short name : Synchronous tumor site Cancer;
LOINC description : Patients presenting with more than one histologically distinct malignancy may be classified
as having synchronous tumors. Multiple primary malignancies (MPMs) are divided into
2 categories: 'synchronous', when tumors arise independently and within 6 months from
the primary malignant tumor or 'metachronous', when the interval is longer (greater
than 6 months). This term is used to report the location of the other synchronous
tumor(s). This term was created for, but not limited in use to, the Colorectal Cancer
Structured Reporting Protocol (2nd Edition, 2012) developed by the Royal College of
Pathologists of Australasia (RCPA).;
