双侧原发性乳腺癌的预后影响因素分析

目的 :研究双侧原发性乳腺癌的预后及其影响因素。方法 :对经病理证实的 30例双侧原发性乳腺癌患者进行分析。结果 :腋淋巴结无转移患者的 5年生存率 ( 64 7% )明显高于腋淋巴结转移的患者 ( 30 8% )。肿瘤直径 <2cm的患者 5年生存率 ( 62 5% )明显高于肿瘤直径≥ 2cm的患者 ( 4 5 5% )。ER受体阳性患者的 5年生存率 ( 66 7% )明显高于ER受体阴性患者 ( 38 9% )。结论 :双侧原发性乳腺癌的预后取决于腋窝淋巴结有无转移 ,肿瘤大小以及ER受体是否阳性。其中腋淋巴结有无转移是影响预后的一个重要指标。

Diagnosis of Bilateral Primary Mammary Cancer and Analysis of Its Prognosis

Objective To discuss the bilateral primary mammary cancer and analyze its prognosis.Methods Analysis to 30 cases of patients with bilateral primary mammary cancers under pathological confirmation.Results The surviving rate of the patients without transfer of lymph node (64.5%) is obviously higher than that of patients with transfer of axilla lymph node (30.8%).The surviving rate of the patients with tumors smaller than 2 cm in diameter (62.5%) is higher than that of patients with tumors not smaller than 2 cm in diameter (45.5%).The five year up surviving rate of patients with ER positive receptor (66.7%) is obviously higher than that of the patients with ER negative receptor (38.9%).Conclusions The prognosis of bilateral primary mammary cancer is decided by whether axilla lymph node has transferred,whether the tumor is big or small,and whether the ER receptor is positive.Above all,whether there's axilla lymph node is a major factor to influence its prognosis.
