Breast cancer screening programs often encounter challenges related to high costs and limited accessibility, particularly in rural areas. Mobile mammography units (MMUs) have emerged as a potential solution to address these barriers. This study aimed to compare the outcomes of mammography screenings conducted in fixed units and MMUs, focusing on recall rates, follow-up adherence, and screen-detected breast cancer (BC) rates.
This retrospective study analyzed data from 790 women aged 50-69 years who underwent mammography screening between January and February 2023. Participants were divided into two groups: group A (525 women, screened at fixed units) and group B (265 women, screened at MMUs). Key metrics included recall rates, biopsy rates, screen-detected BC rates, and refusal rates for follow-up evaluations. Statistical comparisons were made between the two groups to assess differences in outcomes.
In group A (mean age 58.8 ± 5.7 years), the recall rate was 6.1%, with 32 recalls, 8 biopsies, and 7 confirmed BC cases, yielding a screen-detected BC rate of 1.33%. In group B (mean age 59.6 ± 5.8 years), the recall rate was higher at 10.6%, with 28 recalls, 5 biopsies, and 3 BC cases, resulting in a screen-detected BC rate of 1.13%. Notably, refusal rates for follow-up evaluations were significantly higher in group B (42.9%) compared to group A (9%).
While MMUs improve accessibility to underserved areas, they face challenges such as higher refusal rates for follow-up evaluations. The comparable screen-detected BC rates between MMUs and fixed units underscore the potential of combining both approaches in breast cancer screening programs. These findings highlight the importance of awareness campaigns to improve follow-up adherence and suggest that future research should focus on cost-effectiveness and sociocultural factors to optimize breast cancer prevention strategies.
乳腺癌筛查项目常常面临与高成本和可及性有限相关的挑战，尤其是在农村地区。移动乳腺摄影设备（MMU）已成为应对这些障碍的一种潜在解决方案。本研究旨在比较在固定设备和移动乳腺摄影设备上进行的乳腺摄影筛查结果，重点关注召回率、后续随访依从性以及筛查发现的乳腺癌（BC）率。
这项回顾性研究分析了2023年1月至2月期间接受乳腺摄影筛查的790名年龄在50 - 69岁女性的数据。参与者被分为两组：A组（525名女性，在固定设备上进行筛查）和B组（265名女性，在移动乳腺摄影设备上进行筛查）。关键指标包括召回率、活检率、筛查发现的乳腺癌率以及后续评估的拒绝率。对两组进行统计比较以评估结果差异。
A组（平均年龄58.8 ± 5.7岁）的召回率为6.1%，有32次召回，8次活检，7例确诊乳腺癌病例，筛查发现的乳腺癌率为1.33%。B组（平均年龄59.6 ± 5.8岁）的召回率较高，为10.6%，有28次召回，5次活检，3例乳腺癌病例，筛查发现的乳腺癌率为1.13%。值得注意的是，B组后续评估的拒绝率（42.9%）显著高于A组（9%）。
虽然移动乳腺摄影设备提高了服务不足地区获得筛查的机会，但它们面临诸如后续评估拒绝率较高等挑战。移动乳腺摄影设备与固定设备筛查发现的乳腺癌率相当，这凸显了在乳腺癌筛查项目中结合两种方法的潜力。这些发现强调了开展宣传活动以提高后续随访依从性的重要性，并表明未来研究应关注成本效益和社会文化因素，以优化乳腺癌预防策略。
