目的 :探讨如何降低乳腺癌术后患侧上肢功能障碍的发生率。方法 :对65例乳腺癌病人分别行根治术和改良根治术病例进行分组对比研究。结果 :根治术与改良根治术随访3年死亡率差异无显著性 ,而患侧上肢功能障碍存在差异显著。结论 :对早期乳腺癌手术方式尽可能选用改良根治术或其它缩小手术方式进行 ,减少并发症的发生 ,提高患者的术后生活质量。 Objective: To explore how to reduce the incidence of upper limb dysfunction in postoperative patients with breast cancer. Methods: 65 cases of breast cancer patients underwent radical mastectomy and modified radical mastectomy cases were compared. Results: There was no significant difference in the 3-year mortality rate between radical mastectomy and modified radical mastectomy. There was significant difference in upper limb dysfunction between the two groups. Conclusion: The method of modified radical mastectomy or other shrinking operation is the best choice for surgical treatment of early breast cancer, which can reduce the incidence of complications and improve the postoperative quality of life of patients.
