摘要
目的探讨乳腺癌新辅助化疗后肿瘤和腋淋巴结及结外软组织病理缓解的影响因素及与预后的关系。方法选择2000年10月至2001年8月在天津肿瘤医院乳腺科接受新辅助化疗、化疗后手术的196例ⅡB~ⅢB期乳腺癌患者。观察肿瘤、腋淋巴结及结外软组织病理缓解的程度,分析影响病理缓解的因素,及病理缓解与预后的关系。随访率100%,中位随访期61个月(4~70个月)。结果新辅助化疗后肿瘤的病理完全缓解 pCR20例(10.2%),病理部分缓解 pPR108例(55.1%),病理无变化 pSD68例(34.7%),27.0%的转移淋巴结降期。病理缓解率与患者年龄、临床分期无关(P>0.05),与肿瘤大小、激素受体状况、病理类型相关(P<0.01)。5年总生存率62.8%(P<0.01),中位生存期为61个月(P<0.01)。结论病理缓解率与肿瘤大小、激素受体状况、病理类型相关。新辅助化疗后原发瘤和转移淋巴结的降期是重要的预后因素。
