Background: Breast cancer, is increasing in prevalence amongst South East (SE) Asian women, highlighting the need for high quality, early diagnoses. This study investigated radiologists’ detection efficacy in a developing (DC) and developed (DDC) SE Asian country, as compared to Australian radiologists. Methods: Using a test-set of 60 mammographic cases, 20 containing cancer, JAFROC figures of merit (FOM) and ROC area under the curves (AUC) were calculated as well as location sensitivity, sensitivity and specificity. The test set was examined by 35, 15, and 53 radiologists from DC, a DDC and Australia, respectively. Results: DC radiologists, compared to both groups of counterparts, demonstrated significantly lower JAFROC FOM, ROC AUC and specificity scores. DC radiologists had a significantly lower location sensitivity than Australian radiologists. DC radiologists also demonstrated significantly lower values for age, hours of reading per week, and years of mammography experience when compared with other radiologists. Conclusion: Significant differences in breast cancer detection parameters can be attributed to the experience of DC radiologists. The development of inexpensive, innovative, interactive training programs are discussed. This nonuniform level of breast cancer detection between countries must be addressed to achieve the World Health Organisation goal of health equity.
乳腺癌在东南亚女性中的患病率正在上升，这凸显了高质量早期诊断的必要性。本研究调查了与澳大利亚放射科医生相比，一个发展中东南亚国家（DC）和一个发达东南亚国家（DDC）的放射科医生的检测效能。方法：使用包含60例乳腺钼靶病例的测试集，其中20例含有癌症，计算了JAFROC优值（FOM）和ROC曲线下面积（AUC）以及定位敏感性、敏感性和特异性。分别由来自DC、DDC和澳大利亚的35名、15名和53名放射科医生对测试集进行检查。结果：与两组同行相比，DC放射科医生的JAFROC FOM、ROC AUC和特异性得分显著更低。DC放射科医生的定位敏感性显著低于澳大利亚放射科医生。与其他放射科医生相比，DC放射科医生在年龄、每周阅读小时数和乳腺钼靶检查经验年限方面的值也显著更低。结论：乳腺癌检测参数的显著差异可归因于DC放射科医生的经验。讨论了开发廉价、创新、交互式培训项目的问题。必须解决各国之间乳腺癌检测水平不一致的问题，以实现世界卫生组织的健康公平目标。
