Recurrence pattern in the presence of hepatosteatosis in breast cancer: does it facilitate liver metastasis?

Aim: We aimed to investigate the impact of hepatosteatosis (HS) severity on the recurrence pattern of breast cancer and to clarify whether HS causes affinity to recurrence with liver metastasis. Materials & methods: The median follow-up was 80.0 (4-217) months and the mean age was 47.9 ± 11.3 years. Among all, 181 (39.9%) patients were diagnosed with grades 2 and 3 HS. Of total, 158 (34.8%) patients have experienced recurrence. Results: While higher degree of HS was more common in patients presented with liver recurrence (odds ratio; 95% CI: 2.50; 1.27-4.92; p = 0.007), it was lesser in those with other metastatic sites (all were >0.05). Liver-recurrence-free survival was significantly worse in the group with higher degree of HS (hazard ratio; 95% CI: 2.46; 1.4-4.3; p = 0.002) together with younger age (hazard ratio; 95% CI: 2.44; 1.4-4.3; p = 0.002) in multivariate analysis. Conclusion: HS might have produced an affinity for liver metastasis in common types of breast cancer patients in remission independent from metabolic disorders or clinicopathologic features.
