INPWT on Wound Complications & Clinical Outcomes After Lower Extremity Sarcoma Surgery Preop Radiation Therapy Patients

Official Title

The Effect of INPWT on Wound Complications and Clinical Outcomes Following Lower Extremity Sarcoma Surgery in Patients Treated With Preoperative Radiation Therapy: A Multicentre Randomized Controlled Trial


Project Summary - Aggressive soft tissue cancers are commonly treated with radiation followed by surgery. These wounds have a very high rate of wound complications and infection (30%), resulting in more surgeries, longer hospital stays and complex nursing care. Previous research shows that negative pressure (vacuum) dressings applied to the incision at the end of surgery can reduce these complications. The Investigator and his team across Canada will perform a clinical trial comparing standard dressings to these vacuum dressings. The results of this study have the potential to immediately improve the quality of life of soft tissue cancer patients. It can also decrease the amount of time required in hospital and reduce the cost to the Canadian healthcare system.

Trial Description

Primary Outcome:

  • Wound Complication including re-operation for superficial or deep site infection
Secondary Outcome:
  • patient satisfaction
  • Functional outcome
  • Overall cost
This is a Canadian multi-centre randomized clinical trial lead by the Investigator from the Ottawa Hospital and six other orthopedic cancer centres across Canada. The Investigator and the team will be recruiting 248 patients diagnosed with soft tissue cancer who will be treated with radiation therapy followed by surgery. Each of these patients will be randomly assigned to receiving either 14 days of vacuum dressing (Incisional Negative Pressure Wound Therapy) or a standard dressing. Besides this, patients will receive as identical care as possible. The team will then closely follow these patients over a 4 month period to examine for differences in wound complications, length of hospital stay, patient quality of life, patient satisfaction and function. Statistical analysis will be completed by The Ottawa Methods Centre and ethical approval will be obtained at each participating site.
