Purpose In some countries, community access to breast cancer (BC) screening services can be limited for high costs or inaccessibility of fixed clinics, especially in underserved rural areas. To overcome these limitations, care providers introduced mobile mammography units (MMUs): vans or other travelling clinics staffed by healthcare workers and outfitted with equipment for early detection. This study aimed to evaluate the performance and outcomes of MMUs compared to fixed ones in a BC screening program. This evaluation focused on accessibility, diagnostic outcomes,...
Read more Methods and materials We retrospectively analyzed 790 women aged 50–69 years who underwent breast cancer screening using digital breast tomosynthesis (DBT) and 2D synthetic views, between January to February 2023. [fig 1] Participants were divided into two groups: Group A: 525 women screened at fixed units equipped with Hologic Selenia Dimensions Mammographs. Group B: 265 women screened at MMUs equipped with IMS Giotto Class Mammographs. Data collection focused on: Recall rates: The proportion of screenings requiring additional evaluation due to abnormalities. Detection rates: The percentage of screen-detected breast cancer...
Read more Results Detection Rates and Biopsies. Both groups demonstrated comparable breast cancer detection rates: 1.33% for Group A and 1.13% for Group B. Biopsy rates were higher in Group A (25% of recalls) than in Group B (17.9%). Positive predictive values (PPVs) for biopsies were also higher in Group A (87.5%) compared to Group B (60%). [fig 1] Histopathological Findings. Group A identified 7 cases of breast cancer and 1 case of atypical ductal hyperplasia (ADH), while Group B identified 3 BC and 1...
Read more Conclusion This study highlights the effectiveness of MMUs in increasing access to breast cancer screening for underserved populations. While MMUs demonstrated diagnostic performance comparable to fixed units, their higher recall and refusal rates present challenges. These findings underscore the importance of addressing barriers to follow-up care and adherence, particularly in rural or remote areas.To optimize the impact of MMUs, the following recommendations are proposed: Launch targeted awareness campaigns to educate communities about the importance of breast cancer screening and adherence to follow-up...
