Abstract

The molecular pathogenesis of tumors outside the usual tumor spectrum for hereditary nonpolyposis colorectal cancer (HNPCC) is currently controversial. Specifically, it is not known whether these tumors are related to defects in DNA mismatch repair or arise independently of this defect in these patients. Here, we report two young patients, each with a known MSH2 mutation in the family, who developed rare tumors (adrenal cortical carcinoma and anaplastic carcinoma of the thyroid) that are not usually associated with HNPCC. Both of these patients were members of families that fulfilled modified Amsterdam (Amsterdam II) criteria for this familial cancer syndrome. Both the adrenal tumor and the thyroid tumor showed complete loss of immunohistochemical expression for MSH2 protein. Neither tumor was considered microsatellite instability-high following microsatellite instability analysis using the established National Cancer Institute panel of five microsatellite markers. To our knowledge, MSH2 defects in these types of tumors have not been previously reported in patients with the HNPCC syndrome. Our results suggest that microsatellite instability analysis using the National Cancer Institute panel of five microsatellite markers may not detect microsatellite instability in tumors that fall outside the usual tumor spectrum of this syndrome. Therefore, when analyzing unusual tumors in patients with known or suspected HNPCC syndrome, we advocate the performance of immunohistochemistry for mismatch repair gene products in addition to microsatellite instability analysis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
