Brief Summary:

This is a study comparing two methods of dressing a post operative wound that are currently in practice. One method is a traditional dry gauze dressing. The other method is using a negative pressure dressing that provides gentle suction on the wound.

The investigators will attempt to determine how well the use of post-operative negative pressure dressing reduces wound healing problems in patients who have surgery after radiation for a sarcoma in the thigh or leg.

Detailed Description:

Postoperative surgical site infections pose a significant challenge to the orthopaedic oncologist, especially in wounds that have been previously irradiated with neo adjuvant external beam radiation therapy (EBRT). There are many studies demonstrating the relatively high risk of wound complications after lower extremity sarcoma resection. Published data suggest that these preoperatively radiated wounds have a postoperative infection rate of 17%-44% with "traditional" dressings (e.g. dry gauze surgical dressings).

A prospective series of 190 patients and showed a wound complication risk of 35% in preoperative irradiated wounds. The morbidity associated with wound complications can range from moderate (prolonged dressing changes) to severe (life or limb threatening infection). Patients who develop wound complications have been shown to longer hospitalizations and higher costs [ref]. Anatomic location of the tumor has been shown to be a risk factor for the development of wound complications with lower extremities being higher risk than upper extremities. There are several published studies examining the effect of negative pressure wound therapy (NPWT) on high risk surgical wounds. Abdominal wound complications can be reduced with the use of incisional NPWT. In the orthopaedic literature the use of negative pressure incisional dressings have been shown to lower the risk of wound complications in total hip arthroplasty, acetabular fractures, and extremity fractures.

To our knowledge, there have not been any published studies on the utility of negative pressure wound therapy in previously irradiated soft tissue sarcoma wounds. The investigators feel that this high risk patient cohort could potentially benefit from reducing wound complications through NPWT and is an ideal population to study its effect.

Primary Outcome Measures :
  1. Wound Complication Rate [ Time Frame: longitudinally up to 6 months postoperatively ]
    To estimate the wound complication rate of post-operative negative pressure dressings and traditional dry dressings, and risk of secondary interventions after resection of soft tissue sarcoma in lower extremities that have received pre-operative radiation.

Secondary Outcome Measures :
  1. Total Costs [ Time Frame: 6 months ]
    To estimate the on total cost of care and resource utilization in patients treated with negative pressure wound therapy and traditional dry dressings.

Plan Description:

Data safety and monitoring will be provided by the Hollings Cancer Center DSMC. This committee will serve for all sites. The DSMC meets 6 times a year and reviews all MUSC IRB adverse events, protocol deviations/violations, early stopping rules and internal audit results. The PI will be responsible for identifying, reviewing monthly, and reporting adverse events.

Individual participant data will not be shared between the sites. All data will be deidentified and linked with a code.
