Preventive Application of Single-use Negative Pressure Wound Therapy (sNPWT) in the Postoperative Course of Radiotreatated Limb Sarcoma Surgery

Patients will be recruited at the time of the pre-admission visit. During the screening visit the patient will undergo a physical examination and his medical history will be collected. Oncological history and tumor characteristics will be considered and CT-scan imaging will be analysed. ECOG performance status will be reported. If inclusion criteria are respected, the patient will be randomized. The application of the PICO14 study device or standard dressing (dry gauze and plaster) will then be carried out on the day of surgery. For subjects randomized to the treatment arm (Arm A), dressing change with the application of the new PICO14 will occur at day 4+1, day 8±1, and day 14±2. For subjects randomized to the control arm (Arm B), the standard dressing with gauze and plaster is applied. Regardless of the randomization arm the wound assessment via ASEPSIS score will occur at day 4+1, 8±1 and 14±2. During FUP, the dressing can be changed autonomously by the patient if necessary. The information will be recorded on the occasion of the next visit or an extraordinary visit. On day 21, sutures will be removed. On day 30±2, the total ASEPSIS score will be calculated, in order to evaluate the wound healing. From day 14±2, regardless of the randomization arm all patients will be treated with standard dressing. Follow-up visits can be scheduled up to 90 days after surgery.
