Özet

Objective: To determine the associated risk factors for isolated liver metastasis in breast cancer patients and to detect the prognostic factors related to survival. Study Design: Analytical study. Place and Duration of the Study: Department of General Surgery, The University of Health Sciences, Istanbul, Turkiye, from January 2011 to November 2020. Methodology: Patients with breast cancer liver metastasis who experienced surgery were retrospectively analysed for breast cancer and metastases-related characteristics. Descriptive statistical methods were used in the evaluation of data. Survival analyses were estimated by the Kaplan-Meier method. Log-rank and univariable Cox regression tests were utilised to search for prognostic factors' impact on survival. Results: Out of 12 patients, 11 had recurrent disease after a median of 36 months of disease-free survival (DFS) and one patient had de novo metastasis. Grade 3 tumours and increased expression of Ki-67 had a negative effect on DFS. The median follow-up period was 66 months. Survival analysis showed 2- and 3-year progression-free survival (PFS); overall survival rates were 82%, 69%, 92%, and 82%, respectively. Development of liver metastasis in 3 years following breast cancer treatment was linked to worse PFS (p = 0.040). Conclusion: Long-term survival is possible for breast cancer survivors with liver metastasis. Disease-free interval is an important determinant. Longer progression-free survival was detected in patients who had developed metastasis after three years of breast cancer treatment.
