Association between family history of malignant neoplasm with colorectal adenomatous polyp in 40s aged relative person.
We assessed the association between a family history of malignancy and risk of colorectal adenoma among individuals aged 40-49 years.
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.
In total, 2275 participants were included in the study. Univariate analysis showed that old age, male sex, current cigarette smoking, BMI>25kg/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.
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.
