Reconstructive Outcomes of Extensive Soft-Tissue Defects after Palliative Mastectomy for Advanced Breast Cancer

Abstract

Background: In advanced breast cancer, reconstruction can be performed depending on the patient’s situation, and can improve the subsequent treatment and quality of life. We examined the effect of reconstruction after palliative mastectomy on survival and quality of life.Methods: Between April 2010 and April 2021, 40 patients underwent reconstruction after palliative mastectomy for stage-IV breast cancer. To evaluate postoperative satisfaction, changes in the global health and quality-of-life scores after reconstruction were evaluated using questionnaires by the European Organisation for Research and Treatment of Cancer. The survival rate according to reconstructive surgery was estimated by the Kaplan-Meier survival analysis.Results: Reconstruction methods included free transverse rectus abdominis musculocutaneous (TRAM) flap (n=3), pedicled latissimus dorsi (LD) flap (n=3), pedicled TRAM flap (n=2), pedicled LD with pedicled vertical rectus abdominis musculocutaneous flap (n=1), tissue expander insertion (n=3), and split-thickness skin graft (n=28). There were no major complications or decreased life expectancy due to reconstruction. All patients healed well and started conventional chemoradiotherapy at 31.3 days postoperatively. The quality-of-life scores increased from 37 to 83 after reconstruction. There was no difference in the survival rates between those who underwent reconstruction with split-thickness skin graft and flap operation (P>0.05). The mean survival time postoperatively was 43.9 months.Conclusion: Compared to primary closure, reconstruction of extensive soft-tissue defects after palliative mastectomy did not affect life expectancy or delay postoperative chemoradiotherapy; it led to an improved quality of life. Therefore, the extensive defects expected after palliative mastectomy should not influence indications for reconstruction surgery.
