“…The principle of treatment is to perform an extended local resection; otherwise, the disease is likely to relapse and the lesion will then deteriorate. The change may present as fibrosarcomatoid degeneration, which is also called fibrosarcomatoid DFSP in the literature (11)(12)(13). For such patients, we resect as much surrounding tissue as possible and conduct a postoperative frozen section analysis to determine the range of resection, followed by radiotherapy.…”

Background: After thoracic tumor resection, there is often a large area of soft tissue defect left, even with exposed ribs and sternum, which needs to be repaired by skin flap transplantation. This study aims to introduce lateral thoracic flaps combined with local flaps to repair the soft tissue defect of the chest wall after the repair of malignant tumors, and try to retain the latissimus dorsi myocutaneous flap as a spare repair myocutaneous flap to avoid subsequent tumor recurrence and lack of local flaps for supply body source.Methods: A total of 26 patients with chest wall soft tissue defect with or without exposed rib and sternum after tumor resection at presentation from January 2017 to October 2021 were included in this study. None of the patients required breast reconstruction. Patients ranged in age from 34 to 56 years old. The above patients were treated with lateral thoracic flaps combined with local rotational advancement flaps to repair chest wall soft tissue defects. The postoperative wound healing, scar hyperplasia and recurrence of the patients were followed up.Results: Among the patients in this study, 25 incisions healed by primary incision, 1 incision was delayed, and healed after 10 days of dressing change. Postoperatively, the incisions of the patients were all intact, and there were no complications such as skin necrosis and infection. All patients were followed up for 6-18 months, and the incision healed well without complications such as skin necrosis and infection. Of the patients, 2 males developed dermatofibrosarcoma carina recurrence 6 and 10 months after surgery, respectively. After extensive excision, an ipsilateral latissimus dorsi myocutaneous flap was used to repair the defect. The Vancouver scar scale was used to evaluate the hyperplasia of all incisions at 6 months postoperatively. The mean score was 5.92±1.6. Conclusions:The lateral thoracic flap combined with the local flap to repair the chest wall soft tissue defect after tumor surgery is a strategic decision for surgical treatment, which is beneficial to the sequential surgical treatment of tumor patients.
