This study aimed to indirectly examine whether the implementation of clinical breast examination-based screening program in Morocco has been successful in downstaging and improving survival rates. Breast cancer patients detected through the screening pathway were compared with those detected through self-referral over the same period in terms of cancer stage at diagnosis, tumor characteristics, care delays, and survival.
A prospective observational study was conducted between April 2019 and August 2020 at two major public oncology centers.
A total of 896 women with confirmed breast cancer were recruited (483 were program-referred and 413 were self-referred). The authors did not report any significant difference between the two groups in terms of stage at diagnosis, molecular profile, or histopathological grade. Early-stage cancer (stage I-II) was detected in 55.7% of self-referred participants compared to 55.5% of program-referred participants. Median intervals between symptom recognition, pathological diagnosis, and treatment initiation were not significantly different between the two groups. Similarly, survival after treatment showed no significant difference between patients screened by the program and self-referred patients. The 3-year survival rate after treatment was 94.5% for patients referred through the program and 88.6% for patients not referred through the program (p = .16).
This study highlights the importance of equitable and timely access to high-quality diagnosis and treatment facilities, leading to substantial downstaging and enhanced survival rates. Continued efforts to improve quality and expand coverage to include asymptomatic women will consolidate the health infrastructure gains achieved by the Moroccan breast cancer screening program.
本研究旨在间接检验摩洛哥实施基于临床乳房检查的筛查计划是否成功实现了降期和提高生存率。在诊断时的癌症分期、肿瘤特征、护理延迟和生存方面,通过筛查途径发现的乳腺癌患者与同期通过自我转诊发现的患者进行了比较。
这是一项于 2019 年 4 月至 2020 年 8 月在两家主要公立肿瘤中心进行的前瞻性观察性研究。
共纳入了 896 名确诊为乳腺癌的女性(483 名来自计划转诊,413 名来自自我转诊)。两组在诊断时的分期、分子谱或组织病理学分级方面均无显著差异。自我转诊组中早期癌症(I 期-II 期)的检出率为 55.7%,而计划转诊组为 55.5%。两组在症状识别、病理诊断和治疗开始之间的中位间隔时间没有显著差异。同样,治疗后的生存情况在通过计划筛查的患者和自我转诊的患者之间也没有显著差异。治疗后 3 年的生存率在通过计划转诊的患者中为 94.5%,在未通过计划转诊的患者中为 88.6%(p=0.16)。
本研究强调了公平和及时获得高质量诊断和治疗设施的重要性,这导致了显著的降期和提高了生存率。继续努力提高质量并扩大覆盖范围,包括无症状女性,将巩固摩洛哥乳腺癌筛查计划所取得的卫生基础设施收益。
