目的
评价500 mg 氟维司群对绝经后激素受体阳性转移性乳腺癌患者的疗效和安全性。
方法
回顾性分析2012 年2 月至2014 年8 月复旦大学附属肿瘤医院收治的61 例接受500 mg 氟维司群治疗的绝经后ER 阳性转移性乳腺癌患者的临床资料。 评估氟维司群的临床疗效、影响因素和不良反应,并利用Kaplan-Meire 生存分析、Log-rank 检验、COX 比例风险回归模型进行生存分析。
结果
中位随访17.2 个月(2.0 ~32.7 个月)时,本组患者中位无进展生存期(PFS)为6.4 个月,临床获益率为37.7%(23/61),客观缓解率为8.2%(5/61),中位OS 为27.0 个月。 单因素分析(Log-rank 检验)显示,500 mg氟维司群治疗后,患者的PFS 与癌转移后接受内分泌治疗、既往使用他莫昔芬、仅有骨转移及内脏转移显著相关(χ2=3.963、5.197、5.115、5.479,P=0.047、0.024、0.023、0.019)。 COX 比例风险回归分析显示,治疗后患者的PFS 与癌转移后接受内分泌治疗及内脏转移有关(HR=3.1,95%CI: 1.1 ~8.8,P=0.036;HR=2.3,95%CI:1.2 ~4.3,P=0.013),癌转移后接受内分泌治疗者疾病进展的风险是未接受者的3.1 倍,伴内脏转移者疾病进展的风险是不伴者的2.3 倍。 本组患者使用500 mg 氟维司群后未出现Ⅲ度及以上不良反应,且未发生治疗相关性死亡。
结论
500 mg 氟维司群治疗绝经后ER 阳性转移性乳腺癌患者的疗效和安全性值得肯定。

Objective
To evaluate the efficacy and safety of 500 mg fulvestrant for the treatment of postmenopausal patients with ER-positive metastatic breast cancer.
Methods
We retrospectively analyzed the clinical data of 61 metastatic breast cancer patients treated with 500 mg fulvestrant in Fudan University Shanghai Cancer Center from February 2012 to August 2014. Clinical efficacy,influencing factors and adverse effect were evaluated. Kaplan-Meire analysis, Log-rank test and Cox proportional hazard regression model were used for survival analysis.
Results
After the median follow-up of 17.2 months (2.0 -32.7 months), median progression free survival (PFS) was 6.4 months, clinical benefit rate was 37.7%(23/61), objective response rate was 8.2% (5/61) and median OS was 27.0 months. Log-rank test showed that after the treatment of 500 mg fulvestrant, PFS was significantly correlated with endocrine therapy after metastasis, prior tamoxifen use, bone metastasis alone and visceral metastasis (χ2 = 3.963,5.197,5.115,5.479;P = 0.047,0.024,0.023,0.019). COX proportional hazard regression analysis indicated that PFS was correlated with relevant endocrine therapy after metastasis and visceral metastasis respectively (HR = 3.1,95% CI: 1.1 - 8.8,P=0.036;HR=2.3,95%CI:1.2-4.3,P=0.013). The patients receiving endocrine therapy had the risk of disease progression 3.1 times of that in those receiving no hormonal therapy. The patients with visceral metastasis had the risk of disease progression 2.3 times of that in patients without visceral metastasis.
Conclusion
The treatment of 500 mg fulvestrant has a favorable efficacy and safety for postmenopausal patients with ER-positive metastatic breast cancer.
