The prognostic significance of immunohistochemically detected lymph node micrometastases in colorectal carcinoma
Abstract
Micrometastases have been detected by immunocytochemical means in the lymph nodes of patients with otherwise node‐negative cancer of the colon and rectum. This study examines the incidence and prognostic significance of nodal micrometastases in Dukes' B carcinoma. Five hundred and fifty‐nine lymph nodes from 77 cases of Dukes' B carcinoma were examined for lymph node micrometastases by immunocytochemical staining for cytokeratin AE1:AE3. Micrometastases were detected in 19 cases (25 per cent). Cell clusters were present in ten cases, the remaining nine cases displaying only single cells. The presence of micrometastases was unrelated to age ( P = 0·06), sex ( P = 0·32), tumour site ( P = 0·37), tumour size ( P = 0·67), or tumour differentiation ( P = 0·66). Ten‐year survival estimates by the Kaplan–Meier lifetable method was 47 per cent in patients with and without micrometastases (χ 2 = 0·35 and 1 df, P = ns). The presence of nodal micrometastases detectable only by immunocytochemistry in patients with Dukes' B colorectal cancer does not justify reassignment to a more advanced disease stage.

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.
