[Colorectal adenocarcinoma in patients with familial anamnesis positive for malignant neoplasms of the large intestine].
Familial aggregation of colorectal cancer occurs also among sporadic cases that are not part of defined genetic syndromes. First degree relatives of patients with "sporadic" colorectal cancer have a 3-4 fold increased risk of the same cancer. The aim of the present study is to investigate the relationship between a first degree family history of colorectal cancer and pathological and clinical features of the tumor (site, Dukes' stage, age at diagnosis, sex and survival of patients). 461 patients with colorectal cancer were evaluated (250 males and 211 females) after obtaining informations about their family history of cancer. 52 (11.25%) of them reported to have at least one close relative affected by intestinal cancer. Sex, age and stage of the disease are the only parameters that significantly affect survival. No relationship between family history of colorectal cancer and prognostic variables was observed.
