Association between family history of malignant neoplasm with colorectal adenomatous polyp in 40s aged relative person
Menée à partir de questionnaires auprès de 2 275 participants âgés de 40 à 49 ans et ayant subi une coloscopie, cette étude évalue l'association entre des antécédents familiaux de cancer colorectal et le risque de polypes adénomateux du côlon-rectum
Purpose : We assessed the association between a family history of malignancy and risk of colorectal adenoma among individuals aged 40–49 years. Methods : The study population consisted of subjects, aged in their 40s, who underwent colonoscopy. Their family histories of cancer were collected with a self-administered questionnaire. A logistic regression model was used to assess the association between a family history of cancer and the risk of colorectal polyp. Results : In total, 2275 participants were included in the study. Univariate analysis showed that old age, male sex, current cigarette smoking, BMI > 25 kg/m2, and a family history of colorectal cancer (CRC) were risk factors for the development of sporadic colorectal adenomatous polyps in these patients. A multivariate analysis showed that a family history of CRC or kidney cancer was associated with adenoma development. A family history of CRC was also a risk factor for advanced and multiple adenoma. Conclusions : This study shows that a family history of CRC is a risk factor for advanced and multiple colorectal adenoma in people in their 40s. These results support earlier screening for colorectal neoplasms in individuals with a family history of CRC.
