Cancer risk calculator demonstrates ‘good accuracy’
A risk calculator developed by the National Cancer Institute demonstrated accuracy in identifying high-risk colorectal cancer (CRC) patients, according to a study published in the Journal of the American Board of Family Medicine.
The online risk calculator was created using data from the multiethnic cohort study, which followed more than 180,000 patients for the development of CRC for up to 11.5 years through linkages with cancer registries. A statistical analysis was conducted to determine the most important variables linked to the disease, which varied by gender.
Patients in the cohort experienced 2,762 CRC incident cases, which the tool predicted to some level of accuracy.
“The calculator demonstrated good accuracy with a cross-validated c statistic of 0.681 in men and 0.679 in women, and it seems to be well calibrated graphically,” wrote lead author Brian J. Wells, MD, PhD, Cleveland Clinic.
