Purpose
To examine whether patients with a documented family history of breast or colorectal cancer, either positive or negative, were more likely to receive breast or colorectal cancer screening services than those with no documentation.
Methods
Medical record reviews were conducted on 3,433 patients aged 55 and older from four primary care practices in two rural Oregon communities. Data collected included patient demographic and risk information and receipt of screening mammography and/or one of four modalities to screen for colorectal cancer.
Results
Mammography and colorectal cancer screening rates were low in these rural communities, with 50% of average risk women being up-to-date for mammography and 37% of women and 38% of men being up-to-date for colorectal cancer screening according to their risk level. A positive family breast cancer history was associated with an increased likelihood of being up-to-date for mammography screening (OR 2.09, 95% CI 1.45-3.00 relative to a recorded negative history). A positive family history for colorectal cancer was associated with an increased likelihood of being up-to-date with colorectal cancer screening according to U.S. Preventive Services Task Force (USPSTF) low risk guidelines for males (OR 2.89, 95% CI 1.15-7.29) and females (OR 2.47, 95% CI 1.32-4.64) relative to a recorded negative family history. Forty-four percent of the charts of female patients and 56% of the charts of male patients contained no documentation of a family cancer history having been taken. The absence of any recorded family cancer history was associated with a decreased likelihood of being up-to-date for mammography screening (OR 0.70, 95% CI 0.56-0.88 relative to recorded negative history) or for colorectal cancer screening OR 0.75, 95% CI 060-0.96 in females, 0.68, 95% CI 0.53-0.88 in males relative to recorded negative history).
Conclusion
Recording family history of cancer was associated with up-to-date cancer screening, even if the family history was negative. Establishing clinical routines to obtain family history could improve appropriate use of cancer screening.
