Studie som jämför negativt tryckförband med konventionellt hos patienter med resekerade STS efter strålbehandling (TPN-RAD)

10 november 2026 uppdaterad av: Centre Leon Berard

Randomiserad studie som jämför negativt tryckförband kontra konventionellt förband hos patienter med resekerade lem eller bål mjukvävnadssarkom (STS) efter extern strålbehandling

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)

Detaljerad beskrivning

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.

Deltagargrupp / Arm
Intervention / Behandling
Experimentell: Arm A : Surgery for STS and prevena

The 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)

PREVENA™ is a CE-marked class IIa medical device. The PREVENA™ Incision Management System is also intended to manage the environment of closed surgical incisions and surround intact skin in patients at risk for developing post-operative complications, such as infection, by maintaining a closed environment via the application of a negative pressure wound therapy system to the incision.

Inget ingripande: Arm B : Surgery for STS and standard postoperative wound management

The surgery for the STS lesion will be performed according to standard practices.

The dressing and drainage of the wound will be performed according to usual practices, with the exception of negative pressure dressings.
