Säo Paulo med. j; 137 (1), 2019
ABSTRACT CONTEXT: Non-islet-cell-tumor-induced hypoglycemia (NICTH) is caused on rare occasions by secretion of insulin from tumor cells that are reported to have a single tissue origin. CASE REPORT: A 67-year-old male patient had cardia adenocarcinoma and concomitant lung adenocarcinoma with extensi...

Immunoexpression of TS, p53, COX2, EGFR, MSH6 and MLH1 biomarkers and its correlation with degree of differentiation, tumor staging and prognostic factors in colorectal adenocarcinoma: a retrospective longitudinal study

Säo Paulo med. j; 137 (1), 2019
ABSTRACT BACKGROUND: There are cases of colorectal tumors that, although small, show more aggressive evolution than large tumors. This motivated us to study whether there are any proteins capable of alerting about these changes. The aim here was to correlate the immunoexpression of the TS, p53, COX2, E...
