Abstract

The objective of this study is to determine whether the likelihood of returning for routine breast cancer screening differed for false-positive cases depending on the diagnostic work-up. Using the original data from a French population-based breast cancer screening program, we compared the attendance rates at the subsequent round of screening for 16,946 and 1,127 participants who received negative (i.e., American College of Radiology, ACR, categories 1-2) and false-positive mammograms, respectively. False-positive mammograms were categorized ACR 0 (i.e., warranting additional imaging evaluation), 3 (i.e., warranting clinical and imaging follow-up), and 4-5 (i.e., warranting biopsy). We estimated the odds ratios of attendance at subsequent screening round using logistic regression, adjusting for age and history of previous mammography. The attendance rates at the subsequent screening round were 80.6% for women who received negative mammograms versus 69.6, 74.3, and 70.1% for women who received false-positive mammograms warranting additional imaging evaluation, clinical and imaging follow-up, or biopsy, respectively. In comparison to women who received negative mammograms, the corresponding adjusted odds ratios of returning for routine screening were 0.6 [95% confidence interval (CI) 0.4-0.8], 0.8 (95% CI 0.6-0.9), and 0.6 (95% CI 0.4-0.8). No significant differences were found in odds ratios of attendance across ACR categories among women who received false-positive mammograms. Similar figures were observed for attending at least one of the two subsequent screening rounds. In conclusion, in comparison to women with normal or benign findings on index mammograms, false-positive cases warranting additional imaging evaluation, clinical and imaging follow-up, or biopsy had uniformly decreased odds of attending subsequent routine screening rounds.
