[Skin sparing mastectomy with autologous immediate reconstruction: oncological risks and aesthetic results]

Is the oncological safety of skin sparing mastectomy (SSM) with immediate autologous reconstruction and improved aesthetic results comparable to postoperative findings in patients treated with modified radical mastectomy (MRM)?

Sixty patients with T1-2 breast carcinomas and contraindications for breast conserving therapy were treated by SSM and compared to 81 patients of the same age groups and MRM with regard to oncological and aesthetic data. In 33 (55%) patients the nipple areola complex (NAC) could be spared. For autologous tissue TRAM- and Latissimus dorsi-flaps were used. The mean follow-up was 40 (range 20-71) months.

The observed local recurrence rates were not significantly different (p = 0.443) after SSM (n = 3; 5.0%) or MRM (n = 5; 6.2%). Distant metastases and death were seen in 26.7% and 15.0% (SSM), respectively, and in 25.9% and 13.5% (MRM), respectively. Body mass index, operation time and postoperative haemoglobin concentration differed between both groups significantly (p < 0.001) but not the rate of complications (p = 0.232). Aesthetic results of SSM were judged as excellent or good in 90.0% of patients and in 83.4% of surgeons. Nine patients (11.1%) underwent a secondary breast reconstruction after MRM. Furthermore, 12 (14.8%) patients with MRM would prefer a SSM with immediate reconstruction in a similar situation.

Skin-sparing mastectomy improves aesthetic results to a high degree without increasing of local or distant recurrence rates. Skin-sparing mastectomy should be offered to selected patients with breast cancer as an alternative to modified radical mastectomy.
