隐性乳癌(OBC)十分少见,极易误诊、误治,延误病情。目的:为了尽早对OBC确诊,及时处理。方法:我们总结了15年来收治的17例病例,约占乳癌总数的0.34％。首发症状为腋块,1例为锁骨上肿块。术后乳腺标本均作连续切片,检出率为47％。结果:5年生存率为76.4％。结论:(1)OBC首发肿块大多位于腋下,偶可在锁骨上。(2)排除其他系统肿瘤后,腋块一经病理证实为转移腺癌,OBC诊断即可确立。(3)推荐OBC作乳癌改良根治术,同时注意个体化处理、术后放、化疗和综合治疗。
Occult breast cancer (OBC) is very rare, it is easy to misdiagnose, mistreatment, and delay the disease. Purpose: To diagnose OBC early and deal with it as soon as possible. Methods: We summarized 17 cases that were treated in 15 years, accounting for about 0.34% of the total number of breast cancers. The first symptom was a hernia block, and one case was a supraclavicular mass. Postoperative breast specimens were continuously sectioned and the detection rate was 47%. Results: The 5-year survival rate was 76.4%. Conclusions: (1) Most of the first tumors of OBC are located in the axilla, even on the clavicle. (2) After the exclusion of other systemic tumors, the metastatic adenocarcinoma was confirmed by the pathology of the fistula lumps, and the OBC diagnosis can be established. (3) It is recommended that OBC be used for modified radical mastectomy, with individual treatment, postoperative radiotherapy, chemotherapy, and comprehensive treatment.
