[Tolerance of latissimus dorsi without implant to radiotherapy in immediate breast reconstruction].

Objectives: Rates of immediate breast reconstruction (IBR) after mastectomy are currently increasing, leading us to evaluate outcomes of breast reconstruction with latissimus dorsi without implant followed by adjuvant radiotherapy.
Materials and Methods: From January 1999 to August 2013, 31 breast reconstructions with latissimus dorsi have been irradiated. Patients have been selected from a prospective database and contacted to evaluate outcomes of breast reconstruction, and 2 patients have been lost.
Results: Median follow-up was 6.5 years. Breast reconstruction outcomes were evaluated as very good or good in 86% of cases, with breast reconstructed consistency as very good or good in 93% of cases. An additional fat grafting has been performed for 58% of cases (mean volume transferred of 250 cc) and was associated with contralateral breast reduction in 32% of the whole population. IBR was judged as essential for 79% of women a posteriori.
Conclusion: In our experience, latissimus dorsi has a good tolerance to adjuvant irradiation, and may be offered to patients willing to benefit of an IBR even if postoperative radiotherapy is scheduled.
