Accuracy of selfreported cancer-screening histories: a meta-analysis. Cancer Epidemiol Biomarkers Prev 2008; 17: 748–57

Abstract

Abstract Background: Survey data used to study trends in cancer screening may overestimate screening utilization while potentially underestimating existing disparities in use. Methods: We did a literature review and meta-analysis of validation studies examining the accuracy of selfreported cancer-screening histories. We calculated summary random-effects estimates for sensitivity and specificity, separately for mammography, clinical breast exam (CBE), Pap smear, prostate-specific antigen testing (PSA), digital rectal exam, fecal occult blood testing, and colorectal endoscopy
