Incidence of angiolymphatic invasion in colorectal cancer

angiolymphatic invasion (ali) in colorectal cancer (crc) is considered as an important independent prognostic factor and may influence therapeutic decisions. objective: this aim of the study is to find the incidence of ali in histopathological reports of surgical specimens from patients who underwent surgical treatment of colorectal adenocarcinoma. results: one hundred and twenty seven patients were male (50.6%) and the mean age was 60 years old. the overall incidence of ali was 44.6%, and there was a significant association with age (p=0.016), lymph node involvement (n) (p<0.00001) and tumor differentiation (p=0.0039). conclusion: there was a higher probability of finding ali in younger patients, with a higher number of lymph node metastases and a lower tumor differentiation.
