In Mexico and the world, breast cancer is the cancer type with the highest incidence and mortality for women. Its incidence has increased due to a higher life expectancy and a higher exposure to risk factors. Screening is done by mammography using the BIRADS (Breast Imaging Reporting and Data System) system, the standard for mammography screening report which classifies lesions assigning recommendations for patient follow-up. The system goes from 0 (not conclusive) to 6 (demonstrated malignancy), being of interest for this study the BIRADS 0 category.
To describe patients classified as BIRADS 0 by mammography and their reclassification in a first-level hospital during 2021.
Retrospective, descriptive, cross-sectional, observational study. Women over 40 years with a BIRADS 0 result were studied. The following databases were used: Institutional Cancer Registry, Family Medicine Information System, Electronic Clinical File, and the mammography and patient list from preventive medicine.
Reclassification by ultrasound (US) was achieved in 100% of patients, in all of the BIRADS US categories. In 3.8% of BIRADS 0 patients, ductal adenocarcinoma was found and confirmed by histological testing.
All of the reassessed lesions with US were adequately reclassified.
在墨西哥乃至全球，乳腺癌是女性中发病率和死亡率最高的癌症类型。由于预期寿命延长和风险因素暴露增加，其发病率有所上升。筛查通过使用乳腺影像报告和数据系统（BIRADS）的乳房X线摄影进行，该系统是乳房X线摄影筛查报告的标准，对病变进行分类并为患者随访提供建议。该系统从0（不确定）到6（确诊为恶性），本研究关注的是BIRADS 0类别。
描述2021年在一家一级医院中被乳房X线摄影分类为BIRADS 0的患者及其重新分类情况。
回顾性、描述性、横断面观察性研究。研究对象为40岁以上BIRADS 0结果的女性。使用了以下数据库：机构癌症登记处、家庭医学信息系统、电子临床档案以及预防医学的乳房X线摄影和患者名单。
所有患者均通过超声（US）实现了重新分类，涵盖所有BIRADS超声类别。在3.8%的BIRADS 0患者中发现了导管腺癌，并经组织学检测确诊。
所有经超声重新评估的病变均得到了充分的重新分类。
