Abstract

Invasive micropapillary carcinoma is associated with frequent lymph node metastasis and adverse clinical outcome. Initially described as a variant of breast and ovarian carcinoma, it has subsequently been found in other organs, most recently the colon. Reports of […]

INTRODUCCIÓ I OBJECTIU

Les mutacions de l’oncogen KRAS, presents al 30-50% dels carcinomes colorectals, expliquen la manca de resposta a inhibidors dels receptors EGF. L’objectiu de l’estudi és confirmar, mitjançant un estudi multivariant, les correlacions observades en un estudi univariant inicial entre l’estat mutacional de KRAS […]

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 […]
