目的探讨副乳腺癌的诊断和治疗方法。 方法回顾性总结我院收治的1例副乳腺癌患者的临床病理资料，并结合相关文献进行分析。 结果该例患者临床表现为左腋下肿块，彩超及钼靶检查均提示恶性可能性大，病理报告证实为副乳腺癌。 行左副乳腺和左乳腺切除加左腋窝低位淋巴结清扫术，术后病理报告： 左副乳腺浸润性导管癌Ⅱ级，左副乳腺内见浸润性导管癌组织，淋巴结无转移。术后给予化疗（EC×4序贯T×4），生存9个月，现仍在随访中。 结论对腋下肿块而双乳未见确切肿块的患者应警惕副乳腺癌的存在，以免延误诊治。
ObjectiveTo explore the clinical application of oncoplastic surgery in breast-conserving surgery after neoadjuvant chemotherapy.MethodsFrom May 2016 to May 2018, 32 breast cancer patients (cT2–3N0–3M0) who were scheduled for neoadjuvant chemotherapy (NAC) and agreed to accept breast-conserving surgery after NAC in the Henan Tumor Hospital were enrolled into the retrospective study. These patients were originally unable to perform traditional breast conserving surgery because of the size or location of the tumor. We observed the success rate, safety and cosmetic effects of breast-conserving therapy, which were applicated of tumor down-staging after neoadjuvant chemotherapy combined with oncoplastic surgery.ResultsIn this study, after neoadjuvant chemotherapy, 31 patients achieved CR or PR, and 1 patient had SD. All 32 patients underwent breast-conserving surgery successfully, 3 patients underwent breast-conserving combined with volume replacement, and 29 patients underwent breast-conserving combined with volume displacement. One patient was not satisfied with the cosmetic effects, the other patients were satisfied or basically satisfied with the cosmetic effects. The median follow-up was 18 months (5–24 months), and no local recurrence or distant metastasis was found in 32 patients.ConclusionsBy tumor down-staging after neoadjuvant chemotherapy combined with oncoplastic surgery, we can make some patients who are originally not suitable for breast conserving due to tumor size and tumor location succeed in breast-conserving therapy, and the safety and cosmetic effect are basically satisfied.
