Overview
Laboratory findings consistent with the diagnosis of hereditary nonpolyposis colorectal cancer are mainly related with the evaluation of genetic mutations; such as the germline testing for MMR (MLH1, MSH2, MSH6, and PMS2) or EPCAM gene testing. Other laboratory findings include: GCBC, FOBT, serum CEA, CA 19-9 concentration and CA 125, serum iron concentrations, serum vitamin B12 and folate concentrations, liver function tests, and pulmonary function tests.[1]
Laboratory tests
Germline testing
- EPCAM gene is required to establish the diagnosis of HNPCC.[1]
CEA
- CEA are glycosyl phosphatidyl inositol (GPI) cell surface anchored glycoproteins whose specialized sialofucosylated glycoforms serve as functional colon carcinoma L-selectin and E-selectin ligands, which may be critical to the metastatic dissemination of colon carcinoma cells.
CA 125
- CA 125 test may be used to look for early signs of ovarian cancer in women with a very high risk of the disease.
