《临床肿瘤学杂志》(JCO)5月31日在线发表的一项研究表明,使用β受体阻滞剂(BB)与乳腺癌患者无复发生存(RFS)而非总生存(OS)改善有关。
该研究回顾性分析了1995~2007年间接受新辅助化疗的1413例乳腺癌谁患者。研究对比了开始新辅助化疗时接受BB治疗的患者与未接受BB治疗的患者,采用χ2检验比较两组患者的病理学完全缓解(pCR)率,采用Cox比例风险模型确定BB摄入、RFS和OS的关联。
结果显示,使用BB治疗组(A组)和未使用BB治疗组(B组)分别纳入了102例和1311例患者。A组患者倾向于年龄偏大和肥胖(P<0.001)。两组患者pCR比例没有显著差异(P=0.48)。在校正了年龄、种族、肿瘤分期、肿瘤分级、受体状态、淋巴管浸润、体质指数(BMI)、糖尿病、高血压和血管紧张素转换酶抑制剂使用以后,BB摄入与更好的RFS显著相关[风险比(HR)为0.52,95%可信区间(CI)为 0.31~0.88]但与OS改善无关(P=0.09)。在三阴性乳癌(TNBC)患者中(377例),BB摄入与RFS改善有关(HR为 0.30,95%CI为0.10〜0.87,P=.027),但与OS改善无关(HR为0.35,95 %CI为0.12〜1.00,P=0.05)。
英文摘要:
Purpose To examine the association between beta-blocker (BB) intake, pathologic complete response (pCR) rates, and survival outcomes in patients with breast cancer treated with neoadjuvant chemotherapy.
Patients and Methods We retrospectively reviewed 1,413 patients with breast cancer who received neoadjuvant chemotherapy between 1995 and 2007. Patients taking BBs at the start of neoadjuvant therapy were compared with patients with no BB intake. Rates of pCR between the groups were compared using a χ2 test. Cox proportional hazards models were fitted to determine the association between BB intake, relapse-free survival (RFS), and overall survival (OS).
Results Patients who used BBs (n = 102) were compared with patients (n = 1,311) who did not. Patients receiving BBs tended to be older and obese (P < .001). The proportion of pCR was not significantly different between the groups (P = .48). After adjustment for age, race, stage, grade, receptor status, lymphovascular invasion, body mass index, diabetes, hypertension, and angiotensin-converting enzyme inhibitor use, BB intake was associated with a significantly better RFS (hazard ratio [HR], 0.52; 95% CI, 0.31 to 0.88) but not OS (P = .09). Among patients with triple-negative breast cancer (TNBC; n = 377), BB intake was associated with improved RFS (HR, 0.30; 95% CI, 0.10 to 0.87; P = .027) but not OS (HR, 0.35; 95% CI, 0.12 to 1.00; P = .05).
Conclusion In this study, BB intake was associated with improved RFS in all patients with breast cancer and in patients with TNBC. Additional studies evaluating the potential benefits of beta-adrenergic blockade on breast cancer recurrence with a focus on TNBC are warranted.
