Reconstruction des pariétectomies thoraciques effectuées pour récidive de cancer du sein

Some recurrences of breast cancer require wide chest wall resection as curative or palliative therapy. We report a retrospective review of 14 chest wall resections and reconstructions. The width of the anterior chest wall excision was 150 cm2 (80 to 360 cm2). Two defects were full-thickness ones, with sternal or costal resection. The reconstruction required synthetic mesh covered by a latissimus dorsi musculocutaneous flap. The 12 other resections were superficial ones, and have been covered by a skin graft in 5 patients, and by a regional flap in 7 patients (5 latissimus dorsi, 1 DIEP, and 1 bilobed flap). Two patients had a chest wall irradiation after the surgical procedure. We have analysed the factors, which had influenced our choice of the type of reconstruction. The reconstruction is performed by a regional flap, most commonly a latissimus dorsi pedicled flap, in case of full-thickness defect, of nodular isolated recurrence, or when a radiation therapy is provided after the surgical procedure. The coverage is made by a skin graft in case of palliative excision, or of multiple nodular chest wall recurrence (which have a high risk of recurrence in the same form).
