Oncologic safety of skin-sparing mastectomy followed by immediate breast reconstruction: rate and localization of recurrences, and impact of reconstruction techniques

Oncologic safety of skin-sparing mastectomy followed by immediate breast reconstruction: rate and localization of recurrences, and impact of reconstruction techniques Introduction: Oncological safety of skin-sparing mastectomy followed by immediate breast reconstruction is widely debated. Current evidence is relatively poor since it is based mostly on short-term follow-up data of highly selected patient populations. Aim: Recurrence rates of a large cohort of non-selected patients, i.e. "all-comers" were analyzed during a 10-year follow up. Methods: Patient records and follow-up data of 253 consecutive cases treated with of skin-sparing mastectomy and immediate breast reconstruction between 1995 and 2000 were studied. During this time period "all-comers" policy was applied, which meant that all patients treated with mastectomy were offered immediate breast reconstruction regardless of tumour stage. Results: "All-comers" approach resulted in a large proportion of patients with more advanced disease. During the 112 months mean follow-up 8.2% locoregional, 2.9% local, 10.6% distal and 18.8% overall recurrence rates were detected. Breast cancer specific survival rate was 90.9%. Autologous breast reconstruction was applied more frequently in patients with higher tumour stage; therefore recurrence rate was higher compared to patients undergoing implant-based reconstruction. Conclusion: Based on these long-term follow-up data skin-sparing mastectomy combined with immediate breast reconstruction is an oncologically safe treatment option. Therefore, application of "all-comers" policy for breast cancer patients treated with skin-sparing mastectomy followed by immediate breast reconstruction is feasible. Orv. Hetil., 2013, 154, 163-171.
