Objective: To retrospectively assess the size change of hepatic hemangiomas（HH） in hormone receptor positive (HR+) breast cancer patients after comprehensive treatment. Methods: Totally 364 confirmed invasive breast cancer cases with HH were diagnosed at the Breast Cancer Center of Yunnan Cancer Hospital in 2013-2018 by abdominal color Doppler ultrasound (ADUS) + contrast enhanced ultrasound (CEUS) and at least one upper abdominal CT imaging examination. Follow-up was 6-78 months, and changes in location, number and size of HH at different treatment stages were compared between the HR+ and 85 HR- groups. Subgroup analysis of patients receiving chemotherapy and endocrine therapy was also performed. Results: Totally 323 patients were enrolled, including 238 HR+ (73.7%) and 85 HR- (26.3%) cases. Changes in the longest diameter were similar in both groups (P=0.556), and size change of HH was not associated with axillary lymph node metastasis of breast cancer (P>0.05). HH showed no change during chemotherapy but was significantly enlarged after chemotherapy (P<0.01). There was no significant difference between the tamoxifen (TAM; endocrine drug) only and combination or sequential endocrine treatment (P>0.05) groups. Only the aromatase inhibitor group showed statistical significance (P<0.05) in the AI (letrozole, anastrozole and exemestane) group at the t1 time point. Conclusion: During chemotherapy and endocrine therapy for breast cancer patients with HH, the size of HH changes in some patients, while others develop new HH. No significant effect on size change of HH was observed in this study.
