Predictive role of hand-foot syndrome in patients receiving capecitabine plus bevacizumab for HER2-negative locally recurrent/metastatic breast cancer / 肿瘤

ABSTRACT

Objective: To observe the correlation between hand-foot syndrome (HFS) and prognosis of patients with human epidermal growth factor receptor 2 (HER2)- negative locally recurrent/metastatic breast cancer (LR/mBC) receiving chemotherapy with capecitabine (CAP) plus bevacizumab (BEV). Methods: One hundred patients with HER2-negative LR/mBC receiving first-line CAP plus BEV were divided into HFS group and non-HFS group, then the relationship between HFS and clinicopathologic characteristics of patients with HER2-negative LR/mBC and the related factors influencing the progression-free survival (PFS) and overall survival (OS) were analyzed by COX proportional hazards model. Results: There were statistically significant differences in menopausal status and the number of metastatic organs between HFS group and non-HFS group (all P < 0.05). The median PFS of the HFS group was significantly longer than that of the non-HFS group (10.7 months vs 5.8 months, P = 0.007). The median survival time of the HFS group was also significantly longer than that of the non-HFS group (22.8 months vs 14.9 months, P < 0.001). There was an association of Eastern Cooperative Oncology Group (ECOG) performance status (PS) score, hormone receptor status, metastasis at first diagnosis, metastatic organ site, the number of metastases and HFS with PFS (all P < 0.05). ECOG PS score, hormone receptor status, metastasis at first diagnosis, metastatic organ site and HFS were independent risk factors for PFS (all P < 0.05). There was an association of menopausal status, ECOG PS score, hormone receptor status, metastasis at first diagnosis, the number of metastatic organ and HFS with OS (all P < 0.05). Menopausal status, hormone receptor status, metastasis at first diagnosis, and HFS were independent risk factors for OS (all P < 0.05). Conclusion: HFS can be used as a predictor of therapeutic effect of HER2-negative LR/mBC patients receiving CAP-BEV. The patients with HFS have a better prognosis than patients without HFS.
