目的：旨在了解乳腺癌术后局部复发相关因素的相关关系。方法：收集我院５０～８０年代手术治疗的乳腺癌８８２例的临床随访资料，其中１１５例为术后局部复发。采用多元回归（后退法）方法逐步将不显著因素剔除，留下显著性因素建立多元回归方程。结果：腋淋巴结转移、病理类型和ＡＢＯ血型与乳腺癌术后局部复发时间呈负相关性，临床分期和手术方式与乳腺癌术后局部复发时间呈正相关性。结论：腋淋巴结转移、病理类型和ＡＢＯ血型是乳腺癌术后局部复发加快、复发时间缩短的因素；临床分期和手术方式是延长乳腺癌术后局部复发时间的因素，其关系分别是：Ⅰ＞Ⅱ＞Ⅲ＞Ⅳ；扩大根治术＞经典根治术＞改良根治术＞单纯乳房切除术
OBJECTIVE: To investigate the correlation between factors associated with local recurrence after breast cancer surgery. METHODS: Clinical follow-up data of 882 cases of breast cancer surgically treated in our hospital from the 50th to the 80s were collected, 115 of which were local recurrences. Multiple regression (backward) method was used to gradually remove insignificant factors, leaving significant factors to establish multiple regression equations. RESULTS: Axillary lymph node metastasis, pathological type and ABO blood type were negatively correlated with local recurrence time after breast cancer surgery. Clinical staging and operation methods were positively correlated with local recurrence time after breast cancer surgery. Conclusion: Axillary lymph node metastasis, pathological type and ABO blood group are the factors that accelerate the local recurrence and shorten the time of recurrence after breast cancer surgery. Clinical staging and operation are the factors that prolong the local recurrence time of breast cancer surgery. The relationship is: I> II>III>IV; Extended radical surgery> Classical radical surgery> Modified radical mastectomy> Simple mastectomy
