Mass Survery System Formation of Breast Cancer Detection by Visual Lights and Conservation Surgery and Irradiation of Early Breast Cancer

利用可视化手段，做好早期乳腺癌普查工作，是非常重要的。从5705名居民中，采用集体调查和个人检查的方法，从可触及肿块或高危人群中获得次级应征对象88人。激光透射式光扫描(LTPS)技术被发明并在这项研究中用于88例中的33例。同时行X线钼靶摄影(XMG)和超声检查(US)。US被选择来标准化最终的肿瘤评估。LTPS的异常表现为：1)孤立的异常透光区；2)双侧乳房差异异常；3)乳房组织形态异常或不均匀。LTPS检测肿瘤的灵敏度和特异度分别为50%和83%，与XMG相同。LTPS具有无辐射危害的优点，适合于乳房的重复精确检查。超声引导下活检细胞学检查、XMG核芯活检和CytoGuide计算机辅助活检对最终病理诊断有很大帮助。对30例较早期乳腺癌患者行保乳手术加放疗。平均随访23个月，1例局部复发，2例远处转移，对侧乳腺癌效果较好，副作用少，并发症少。大多数患者对良好的生活质量感到满意。有必要进一步跟进。总结了乳腺癌普查系统与影像、病理诊断相结合，早期乳腺癌保乳手术与放射治疗相结合的重要性。

It is very important to make a good breast cancer mass survey system in the early stage by means of visual lights. From the residents of 5705, mass survey and individual examination were performed to obtain secondary candidates of 88 with palpable mass or from the high risk group. Laser Transmission Photo-Scanning (LTPS) technique was invented and used in this study for 33 out of 88. X-ray mammography (XMG) and Ultrasonography (US) were also performed. US is selected to standardize the final tumor evaluation. Abnormal findings of LTPS were due to 1) isolated abnormal translucency area, 2) abnormal difference between the both breasts and 3) abnormal feature or inhomogeneity of the breast tissue. Sensitivity and specificity of LTPS for tumor detection were 50% and 83% respectively, as in the cases of XMG.LTPS is suitable for repeated precise examinations of the breasts by the advantage of no radiation hazard. US guided aspiration by biopsy cytology and core biopsy with XMG and its conputer-aid by Cytoguide were very useful for the final pathology.Conservation surgery and irradiation was carried out in 30 cases of relatively early stage breast cancer. During the follow up period of average 23 months, one local recurrence, two distant metastasis and opposite side breast cancer revealed rather good result with less side effect and complications. Most of the patients were satisfied with good quality of life. Further follow up is necessary. It concludes the importance of breast cancer mass survey system with image and pathology diagnosis, and good combination of conservation surgery and irradiation of early breast cancer.
