Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi-center randomized clinical trial lead by the Investigator from the Ottawa Hospital and six other orthopedic cancer centers. 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 7 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 period of 4 month to examine 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 Center and ethical approval will be obtained at each participating site.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This is a Canadian multicenter superiority randomized clinical trial in patients who are scheduled to undergo surgical resection of a soft tissue sarcoma treated with either preoperative or postoperative radiation therapy and a primary closure. The participants are randomized to Incisional Negative Pressure Wound Therapy (Acelity) or conventional gauze dressing; the current standard of care.

Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Outcome Assessors

The operative team will remain blinded to the dressing until the time of application. Since wound failure requires the need of medical or surgical intervention, primary outcome of this study is not blinded. However, the treatment arm will be blinded to the Research Coordinator/Outcomes Assessor of secondary outcomes including scar assessment, QoL and Functional Assessment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

VAC Wound Dressing

Limb salvage surgery is performed on sarcoma patients 4-6 week post radiotherapy. These patients will be randomized to receive 7 days of Incisional Negative pressure wound therapy.

Group Type EXPERIMENTAL

Incisional Negative Pressure Wound Therapy (INPWT)

Intervention Type OTHER

A total of 291 patients will be randomized to receive 7 days of Incisional Negative pressure wound dressing. The dressing will be removed 1 week after surgery.

Control Wound Dressing

Limb salvage surgery is performed on sarcoma patients 4-6 week post radiotherapy. These patients will be randomized to receive standard gauze dressing with no negative pressure application.

Group Type ACTIVE_COMPARATOR

Wound Dressing

Intervention Type OTHER

A total of 291 patients will be randomized for standard gauze dressing. This dressing requires no pressure and is applied according to the current standard dressing procedures of the institution. The dressing will be changed every 2-3 days.
