Value of p63 and Cytokeratin 5/6 as Immunohistochemical Markers for the Differential Diagnosis of Poorly Differentiated and Undifferentiated Carcinomas

Abstract

Microsatellite instability (MSI), characterized by contraction or expansion in microsatellite length or short tandem repeats compared with germline lengths, is found in 85% to 90% of colon cancer arising in hereditary nonpolyposis colorectal cancer families. These cancers commonly have characteristic histologic appearances, including medullary features with intense lymphoid infiltrates. In pancreatic cancer, a rare medullary histologic subtype more often demonstrates MSI than the more common adenocarcinoma subtype. We hypothesized that the medullary histologic pattern might correlate with MSI in additional tumor types and analyzed 8 cases of typical and atypical medullary carcinoma of the breast. Tumor and normal DNA was extracted from paraffinized tissue blocks of tumor and histologically uninvolved axillary lymph nodes, respectively. We analyzed the tumors for instability in 5 primary (BAT25, BAT26, D17S250, D5S346, D2S123) and 3 alternative (BAT40, D18S55, D18S58) microsatellites recommended at the National Cancer Institute--sponsored conference for diagnosis of MSI in colorectal cancer. All 8 tumors were microsatellite stable at the 8 loci, suggesting that MSI is not commonly associated with medullary or atypical medullary breast carcinoma, in contrast with the reported association with medullary tumors of the colon and pancreas.

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.
