Luminal亚型浸润性乳腺癌

目的 研究Luminal亚型浸润性乳腺癌的临床特点和生存状况.方法 回顾性分析中国医学科学院肿瘤医院2002年1月1日至9月30日收治的162例接受手术治疗、资料完整的浸润性Luminal亚型乳腺癌的临床资料,对其临床特征、复发及生存情况进行分析.结果 162例患者随访4 ～98个月,中位随访时间92个月,41例患者(25.3％,41/162)出现局部复发或远处转移,包括远处转移32例(19.8％,32/162),局部复发2例(1.2％,2/162)及局部复发合并远处转移7例(4.3％,7/162).总的无病生存率为73.1％,5年无病生存率为79.6％；27例死亡(16.7％,27/162),总生存率为82.5％,5年生存率为85.3％.Kaplen-Meier单因素生存分析显示,肿瘤大小、淋巴结状况、临床分期影响患者的总生存时间(P＜0.05)；肿瘤大小、淋巴结状况、肿瘤分级、临床分期、PR影响患者无病生存时间(P＜0.05).多因素分析显示,TNM分期、PR和PCNA是影响总生存时间的独立影响因素(OR =0.633,95％ CI:0.411～0.976,P ＜0.05; OR =0.823,95％ CI:1.012～ 3.283,P＜0.05);TNM分期和PR是影响无病生存时间的独立影响因素(OR =3.273,95％CI:1.719 ～6.232,P＜0.01; OR=0.599,95％CI:0.423 ～0.850,P＜0.01).结论 在浸润性Luminal亚型乳腺癌中,PR、PCNA状况均能明显影响患者预后.

Luminal subtype invasive breast cancer

Objective To analyze clinical characteristics of invasive Luminal subtype breast cancer.Methods The data of 162 invasive Luminal subtype breast cancer patients receiving operation in Cancer Hospital of Chinese Academy of Medical Science from January 1 st to September 30th in 2002,were collected and the clinical characteristics,recurrences,metastasis and survivals were retrospectively analyzed.Results The median time of follow-up was 92 months,ranging from 4 to 98 months.41 cases (25.3％,41/162) presented local recurrence or metastasis including 32 cases with metastasis ( 19.8％,32/162),2 cases with local recurrences (1.2％,2/162) and 7 cases with both local recurrence and metastasis (4.3％,7/162) ;Disease-free survival (DFS) and the 5-year DFS were 73.1％ and 79.6％,respectively.27 patients ( 16.7％,27/162) died of breast cancer,the overall survival (OS) and 5-year OS were 82.5％ and 85.3％,respectively.According to Kaplen-Meier survival analysis,tumor size,lymph node status and clinical stage were correlated to overall survival time ( P ＜ 0.05 ) ; and rumor size,lymph node starus,grade,clinical stage and PR status were correlated to disease-free survival time ( P ＜ 0.05 ).By multivariate analysis,TNM stage,PR and PCNA were independent prognostic factors correlated to overall survival time (OR=0.633,95％ CI:0.411 -0.976,P＜0.05; OR =0.823,95％ CI:1.012-3.283,P ＜ 0.05) ; TNM stage and PR was independent prognostic factors correlated to disease-free survival time (OR =3.273,95％ CI:1.719 - 6.232,P ＜ 0.01 ; OR =0.599,95％ CI:0.423 - 0.850,P ＜ 0.01 ).Conclusions In invasive Luminal subtype breast cancers,PR is correlated to fine prognosis,and PCNA is correlated to overall survival time.
