KRAS oncogenic mutations, present in approximately 30-50% of colorectal carcinomas (CRC), result in a lack of response to EGFR inhibitors. The aim of this study was to confirm with a multivariate analysis the correlations observed in our initial univariate approach between KRAS mutational status and […]

Background: Micropapillary carcinoma (MC) is accepted as an aggressive variant of colorectal adenocarcinoma, described for the first time in the breast and later in other organs. At present, there are a limited number of colorectal MC series reported, not enough to define […]

Background:

KRAS mutations, present in approximately 30-50% of colorectal carcinomas (CRC) has been recently associated with lack of response to anti-EGFR therapy, poor prognosis and high mitotic activity. Nevertheless, its relation to other histopathological and molecular parameters has not been well established.

Our first approach was to determine […]
