Primary reconstruction after extensive chest wall resection.

Abstract

Chest wall resection and reconstruction has been proven to be a safe surgical procedure. This is particularly useful for breast cancer patients with chest wall recurrences or for those who first present with locally advanced cancer in the chest wall where there is both a large soft tissue and bony defect that need repair. In addition, many of these patients have had irradiation or chemotherapy, which can significantly impair wound healing. Thirty-four patients underwent chest wall resection and primary reconstruction over an 8-year period. Twenty-three patients had breast carcinomas and six had breast and chest wall sarcomas. Of the breast carcinoma patients, 12 had local recurrences and 11 presented with locally advanced primary disease. Bony resection of the chest wall was required in 16 (47%) cases. Thirty myocutaneous flaps (18 rectus abdominis, four pectoralis major, eight latissimus dorsi) and three omental flaps were used for reconstruction. One required a deltovertebral skin flap. Skeletal reconstruction was necessary in four cases. All except one (97%) achieved primary wound healing. There was one mortality (3%) and three patients required further surgery for complications that were related to the reconstruction. Post-resection metastases occurred in 13 (42%) patients and only 2 (6%) had local recurrences. The 2-year survival rate was 78% with a mean survival time of 25.5 months. Primary reconstruction for curative or palliative purposes is a useful and safe surgical procedure for patients with recurrent or locally advanced chest malignancies after extensive chest wall resection. Pedicled myocutaneous flap is the preferred option for skeletal and soft-tissue coverage.
