目的

探讨激素受体(HR)阳性、HER-2阴性(HR+/HER-2-)首发单纯骨转移(BOM)乳腺癌患者的不同一线治疗方式及预后分析。

方法

回顾性分析2001年10月至2018年11月中国人民解放军总医院肿瘤医学部收治的373例女性HR+/HER-2- 乳腺癌BOM患者的临床资料。根据一线初始方案不同,分为首选化疗组(165例,采用化疗方案)和首选内分泌组(208例,采用内分泌治疗方案);初始治疗后无疾病进展生存期≥3个月的患者根据维持方案不同,分为持续化疗组(首选化疗组患者继续化疗)、化疗-内分泌组(首选化疗组患者采用内分泌维持治疗)和持续内分泌组(首选内分泌组患者继续内分泌治疗)。分析不同治疗组间患者的临床病理特征及预后差异,采用Log-rank检验进行预后单因素分析,Cox回归模型进行多因素分析。采用倾向评分匹配及逆概率加权法评估组间均衡性。采用Kaplan-Meier法进行生存分析。

结果

首选化疗组和首选内分泌组患者的中位无进展生存(PFS)分别为10个月(95%CI:6.76~13.23)、12个月(95%CI:10.33~13.66),中位总生存(OS)分别为61个月(95%CI:45.42~76.57)、52个月(95%CI:41.28~62.71),两组比较,差异均无统计学意义(χ2=1.057、1.044,P均>0.05)。倾向评分匹配后,首选化疗组和首选内分泌组均为106例,中位PFS分别为12个月(95%CI:8.70~15.29)、14个月(95%CI:11.48~16.51),差异有统计学意义(χ2=4.254,P=0.039);中位OS差异无统计学意义[68个月(95%CI:49.20~86.79)比64个月(95%CI:51.21~76.79),χ2=0.018,P=0.894]。初始治疗后至少3个月内无疾病进展的患者共332例,其中持续化疗组58例、化疗-内分泌组82例、持续内分泌组192例;3组患者的中位PFS分别为6个月(95%CI:6.74~11.20)、19个月(95%CI:21.60~30.43)、13个月(95%CI:15.45~19.62),差异有统计学意义(χ2=59.586,P<0.001);中位OS分别为48个月(95%CI:46.16~68.64)、72个月(95%CI:70.78~93.54)、54个月(95%CI:61.40~80.91),差异有统计学意义(χ2=5.984,P=0.050)。逆概率加权后,3组患者的中位PFS分别为7个月(95%CI:5.00~12.00)、20个月(95%CI:16.00~25.00)、13个月(95%CI:12.00~16.50),差异有统计学意义(χ2=51.493,P<0.001);中位OS分别为46个月(95%CI:32.00~未达到)、92个月(95%CI:61.00~114.00)、54个月(95%CI:48.00~67.00),差异无统计学意义(χ2=5.334,P=0.069)。Cox多因素分析结果显示,一线不同治疗方式(化疗-内分泌组比持续化疗组:HR=0.02,95%CI:0.01~0.06;持续内分泌组比持续化疗组:HR=0.57,95%CI:0.40~0.81)是PFS的独立影响因素;诊断至复发转移时间(≥24个月比<24个月,HR=0.64,95%CI:0.46~0.89)是OS的独立影响因素。

结论

对于HR+/HER-2-乳腺癌BOM患者,倾向评分匹配后一线首选内分泌治疗患者的中位PFS优于首选化疗,两组患者中位OS相似。对于一线初始治疗后未进展的患者,化疗后转为内分泌维持治疗的效果优于持续化疗或持续内分泌治疗。

Objective

To investigate the efficacy of different first-line treatment methods in hormone receptor-positive, HER-2-negative (HR+/HER-2-) breast cancer patients with bone-only metastases (BOM).

Methods

Clinical data of 373 HR+/HER-2- breast cancer patients with BOM between October 2001 and November 2018 in the Senior Department of Oncology Medicine, Chinese PLA General Hospital were retrospectively analyzed. Patients were divided into two groups according to the different initial treatment, including chemotherapy (CT) group (initial CT group, n=165) and endocrine therapy (ET) group (initial ET group, n=208). Patients without disease progression at least 3 months after initial treatment were divided into different groups based on their maintenance therapy, including continuous CT (CT cohort), maintenance ET following initial CT (CT-ET cohort) and continuous ET (ET cohort). The clinicopathological characteristics and prognostic factors were analyzed between different treatment groups. The log-rank test was used for univariate analysis, and Cox regression model for multivariate analysis. Propensity score matching and standardized mean difference with inverse probability weighting were adopted to evaluate the balance between groups. Survival analysis was performed using the Kaplan-Meier method.

Results

The median progression-free survival (PFS) of patients in the initial CT group and the initial ET group was 10 months (95%CI: 6.76-13.23) and 12 months (95%CI: 10.33-13.66), respectively, while the median overall survival (OS) was 61 months (95%CI: 45.42-76.57) and 52 months (95%CI: 41.28-62.71), respectively. No statistically significant difference was observed between the two groups (χ2=1.057, 1.044, both P>0.05). After propensity score matching, both initial CT and ET group had 106 cases, with median PFS of 12 months (95%CI: 8.70-15.29) and 14 months (95%CI: 11.48-16.51), indicating a significant difference (χ2=4.254, P=0.039); and the median OS was 68 months (95%CI: 49.20-86.79) and 64 months (95%CI: 51.21-76.79), indicating no significant difference (χ2=0.018, P=0.894). A total of 332 patients showed no disease progression for at least 3 months after initial treatment, including 58 in the CT cohort, 82 in the CT-ET cohort, and 192 in the ET cohort. The median PFS for the CT cohort, CT-ET cohort and ET cohort was 6 months (95%CI: 6.74-11.20), 19 months (95%CI: 21.60-30.43), and 13 months (95%CI: 15.45-19.62), indicating a significant difference (χ2=59.586, P<0.001). The median OS was 48 months (95%CI: 46.16-68.64), 72 months (95%CI: 70.78-93.54), and 54 months (95%CI: 61.40-80.91), indicating a significant difference (χ2=5.984, P=0.050). After inverse probability weighting, the median PFS was 7 months (95%CI: 5.00-12.00), 20 months (95%CI: 16.00-25.00), and 13 months (95%CI: 12.00-16.50) in the three corhort, with significant differences among groups (χ2=51.493, P<0.001). The median OS was 46 months (95%CI: 32.00 to not reached), 92 months (95%CI: 61.00-114.00), and 54 months (95%CI: 48.00-67.00), with no statistically significant difference (χ2=5.334, P=0.069). The Cox multivariate analysis results showed that different first-line treatment methods (CT-ET cohort vs CT cohort: HR=0.02, 95%CI: 0.01-0.06; ET cohort vs CT cohort: HR=0.57, 95%CI: 0.40-0.81) was an independent factor affecting PFS; the time from diagnosis to recurrence (≥24 months vs <24 months, HR=0.64, 95%CI: 0.46-0.89) was an independent influencing factor of OS.

Conclusions

In HR+/HER2- breast cancer patients with BOM, after propensity score matching, the median PFS of initial ET was better than that of initial CT among the patients in the front-line preferred endocrine group, and the median OS of the two groups of patients was similar. In patients without progression after initial first-line therapy, the CT-ET cohort yielded better outcomes than CT or ET cohort.
