Results of endoscopic treatment of early colorectal cancer
Abstract
Aim of investigation. To estimate results of diagnostics and endoscopic treatment of patients with suspicion for early colorectal cancer (ECRC).
Material and methods. Overall 46 patients were included in original study with suspicion for ECRC in the period from 2006 to 2010.
Results. Lesions were localized in the left side of the large intestine (45,6%) more frequently, referred into to the type Is (52,2%). The average size was 17,1±6 mm. The «none-lifting sign» had the greater sensitivity and specificity (88 and 100%) for differentiation of penetrating and superficial/no invasion, than intestinal fossas pattern (68 and 92%). At following accepted criteria (high or moderate grade of tumor differentiation, absence of malignant cells at the crust line, absence of vessel invasion, absence of secondary foci, submucosal invasion of no more than 1000 µm or 2-nd Haggit level) no local relapses or metastatic lesions after endoscopic tumor removal were detected.
Conclusions. Endoscopic erasion of early neoplasms of the large intestine is an effictive method of treatment at strict following of radical surgery criteria.
