In addition, the combination of microsatellite instability testing, MLH1 promoter methylation analysis, and BRAF (V600E) mutation analysis can distinguish a sporadic colorectal cancer from one associated with HNPCC, helping to avoid costly molecular genetic testing for germline mutations in mismatch repair genes.

The level of invasive front immune cell staining was significantly higher in mismatch-repair-deficient tumors compared to mismatch-repair-proficient tumors (p < 0.001), but no difference was observed among the different subtypes of mismatch-repair-deficient tumors: Lynch syndrome-associated vs. MLH1-methylated vs. unexplained.

The reference tumor group contained 28 HNPCC with proven germ-line mutations or positive Amsterdam I criteria (median age, 37 years) and loss of MLH1 expression, 14 sporadic MSI-H CRC tumors with loss of MLH1 expression and BRAF V600E mutation (median age, 80.5 years), and 16 sporadic MSS CRC (median age, 76.5 years).

For patients with Lynch Syndrome (LS) (formerly known as hereditary nonpolyposis colorectal cancer or HNPCC), inheritance of one of several mutated mismatch repair genes (MMR) results in an increased risk for a variety of malignancies including colon, rectal, endometrial, urinary tract, gastric, small bowel and others [1].
