Abstract Purpose Our purpose was to evaluate the influence of obesity on clinicopathological characteristics of breast cancer. Secondly we wanted to explore the effect of obesity on the performance of endocrine therapy in Chinese breast cancer patients. Methods Patients with luminal/human epidermal growth factor receptor 2 (HER2)-negative early breast cancer were included and categorized into the non-obese (BMI < 28 kg/m²) and obese (BMI ≥ 28 kg/m²) groups according to body mass index (BMI). Clinicopathological characteristics and treatment modalities were compared among two groups. Furthermore, the interaction of adjuvant endocrine therapy and efficacy between non-obese and obese groups were analyzed. Results A total of 2875 patients were included: 2598 in the non-obese group and 277 in the obese group. A higher rate of patients with comorbidities (OR: 2.83, 95%CI 2.13–3.74, P < 0.001) or PR positive tumor (OR: 1.63, 95%CI 1.03–2.58, P = 0.037) were identified in the obese group. Obesity was not associated with disease recurrence (P = 0.839) or overall survival (P = 0.140) in the whole population. Subgroup analysis did show an association with worse relapse-free survival (RFS, HR 3.48, 95%CI 1.31–9.22, P = 0.012) and overall survival (OS, HR 4.67, 95%CI 1.28–16.95, P = 0.019) in luminal A breast cancer. These results could not be reproduced in the luminal B subtype with a RFS (HR 0.78, 95%CI 0.41–1.49, P = 0.454) or OS (HR 1.17, 95%CI 0.50–2.74, P = 0.727). Furthermore, obesity didn’t impact endocrine therapy effectiveness, neither in Tamoxifen nor aromatase inhibitor group (RFS: interact P = 0.381; OS: interact P = 0.888). Conclusion The impact of obesity on prognosis interacted with luminal subtype status in Chinese breast cancer patients, which was not related with endocrine treatment modality.
