Brief Summary

This is a randomized (1:1 ratio), prospective, comparative, controlled, open-label study. The aim is to compare the efficacy of negative pressure therapy (PREVENA™) versus standard postoperative wound management on the wound healing after surgery for previously irradiated Soft Tissue Sarcoma (STS)

Detailed Description

The gold standard treatment for primary non-metastatic STS is complete surgical resection. Peri-operative Radiation Therapy (RT) has been proved to improve local control . Nevertheless, the timing of RT, whether preoperative or postoperative, remains a debate.

Both have similar local control efficacy, but preoperative RT results in lower rates of long-term fibrosis and lymphedema and improved joint mobility than postoperative RT. On the other hand, the adverse effect of pre-operative RT is a higher rate of wound post-operative complications and re-operations.

Any effort to reduce the high rate of postoperative complications could offer the advantage of preoperative RT in terms of reduced long-term sequelae compared with postoperative RT without a higher wound complication rate postoperatively. Short retrospective series of Negative Pressure Wound Therapy (NPWT) after surgical resection of Soft Tissue Sarcoma (STS) have reported very encouraging results in preventing wound complications: patients treated with NPWT were less likely to develop wound complications than those who did not receive it. Both groups did not report an increased rate of local recurrence. The use of NPWT would also reduce the cost of care by avoiding complications.

That's why the investigators propose this study comparing the use of a negative pressure dressing to a conventional dressing in patients with STS of the limbs or trunk resected after neo-adjuvant external radiotherapy.

Arm A : Surgery for STS and prevenaPrevenaThe surgery for the STS lesion will be performed according to standard practices. PREVENA™ Incision Management System should be applied immediately post-surgery to clean surgically closed wounds. It should be continuously applied for a minimum of 2 days and up to a maximum of 7 days (as per PREVENA user manual)
