In the October 2008 issue of Nature Clinical Practice Gastroenterology and Hepatology, two errors were published in the Review article by Wendy S. Rubinstein and Scott M. Weissman. In Figure 1, in one of the lower boxes discussing the patient's history of lower gastrointestinal adenomas or hyperplastic polyps, the footnote symbol (a) should have been included next to ≤10 ADs. aRecommendation based on clinical judgment; consider reviewing the case with a genetic counselor. In addition, on page 575, left hand column, last paragraph, the second sentence implies that MSI and IHC testing are both unreliable after chemoradiation. The sentence should have read, “Taking multiple biopsies is critical for MSI and IHC studies of rectal cancers as MSI testing is unreliable after chemoradiation, and rectal cancer treatment schemata often involve neoadjuvant therapy.”
