Lineage infidelity and expression of melanocytic markers in human breast cancer

Open access

Abstract

In previous analyses, dual expression of melanocytic and epithelial molecular markers have been described as indicators of lineage infidelity for breast cancer cells that lose their epithelial identity. Here we demonstrated that this is a much more frequent phenomenon in human breast carcinomas, usually affecting only a part of the tumor. Accordingly we detected, in 18 out of 100 breast carcinomas, immunohistochemically focally positive cells for the melanocytic marker Melan A. The presence and extent of Melan A expression was statistically significantly associated with a reduction in tumor cell differentiation, but not tumor type, size, lymph node metastasis, hormone receptor status or Her-2-neu expression. Microarrays of a further 159 breast cancers showed, in several samples, variably low expression levels of Melan A (and other melanocytic markers) that are consistent with focal expression in many tumors. One case strongly overexpressed Melan A. The transition from an epithelial to a melanocytic phenotype (lineage infidelity) appears to occur much more frequently than previously assumed and occurs in restricted areas of breast cancer during tumor progression, a possible association with a reduction in tumor cell differentiation.

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.
