Histoprognostic markers role in colorectal cancer

Malignant tumors with digestive location are, according to the World Health Organization (WHO), a major cause of morbidity and mortality worldwide. In Romania, the constant increase of prevalence and incidence of colorectal cancer awarded it the status of priority public health problem. The study aimed to identify specific aspects of colorectal cancer histoprognosis that may be associated with a higher frequency of the disease. Data were collected from records and registers within Clinic of Medical Oncology, Emergency County Hospital, Craiova, Romania. Were analyzed and associated demographics and epidemiological data, clinical features, anatomotopographical, histopathological and immunohistochemical. The cases studied were adenocarcinomas with a balanced gender distribution and a worrying incidence for Craiova. The age group with the highest incidence was that of 55-64 years. Topographic, rectum and rectosigmoidian junction are the first two locations. More than half of the cases (55.55%) are adenocarcinomas with moderate differentiation and belong to the pT3 category, as extension of colorectal tumor degree. 32.5% of patients were identified with mutations in the K-Ras oncogenes and were found Ki67 positive immunoreacted and heterogeneity of antigen expression in tumor areas studied. Colorectal cancer recorded a worldwide steady increase in the incidence; growth trend in our country is above the European average. Dolj County faces with an increased incidence and mortality rates by this disease. To limit the disease at the population level and pre-malignant diagnosis is necessary to establish histoprognostic value and predictive of tumor markers.
