Most radiologists recommend follow-up mammography in 3 to 6 months for asymptomatic patients with mammographic lesions that do not appear suspicious enough to warrant immediate biopsy. In this retrospective cohort study, the medical records of 776 patients were audited 24 to 35 months after mammography to estimate the frequency of indeterminate lesions, the probability of malignancy, and the rate of patients' compliance with recommendations. Almost 2% of patients retested after an indeterminate mammogram were found to have breast cancer (95% confidence limits 0.2% and 5.9%). Only 26% of the patients retested during the audit period had the test within the suggested upper limit of 6 months. We conclude that timely follow-up after an indeterminate mammogram is advisable and that for the population we studied, compliance with this recommendation is low.
大多数放射科医生建议，对于乳房X光检查发现有病变但又不足以可疑到需要立即活检的无症状患者，应在3至6个月后进行乳房X光复查。在这项回顾性队列研究中，对776例患者乳房X光检查后24至35个月的病历进行了审核，以评估不确定病变的发生率、恶性肿瘤的概率以及患者对建议的依从率。在乳房X光检查结果不确定后再次接受检查的患者中，近2%被发现患有乳腺癌（95%置信区间为0.2%至5.9%）。在审核期间再次接受检查的患者中，只有26%在建议的6个月上限内进行了检查。我们得出结论，乳房X光检查结果不确定后及时进行随访是可取的，而且对于我们研究的人群来说，对这一建议的依从性较低。
