Brief Summary:
The purpose of this research project is to improve the surgical treatment of Soft Tissue Sarcoma (STS) treatment based upon a Randomized Controlled Trial (RCT). We want to evaluate the effect of the use of Negative Pressure Wound Therapy (NPWT) versus a conventional wound dressing on postoperative wound complications after surgical removal of deep-seated high-malignant STS of the extremities or trunk wall.

Arm Intervention/treatment
No Intervention: Standard treatment
Group A: Standard wound closure with staples and conventional wound dressing.
Experimental: Prevena
Group B: Wound closure with staples and Negative Pressure Wound Therapy (PREVENA PLUS™ Incision Management System).
Device: Prevena
RCT (no blinding) where the patients will be randomized to wound closure with staples and either Negative Pressure Wound Therapy (PREVENA PLUS™ Incision Management System) for 7 days or a conventional wound dressing.

Primary Outcome Measures :
  1. Wound complication/healing [ Time Frame: 120 days postoperatively ]

    A major wound complication defined as in O'Sullivan et al. [11]:

    • A secondary surgery under anesthesia for wound repairs such as debridement, operative drainage and secondary wound closure.
    • Wound management without secondary surgery, this includes invasive procedure without anesthesia such as aspiration of seroma and readmission for wound care such as intravenous antibiotic or persistent deep packing within 4 months (120 days) after surgery.

Secondary Outcome Measures :
  1. Secondary outcome measures, hospital stay. [ Time Frame: 1 year postoperatively ]
    Length of hospital stay (measured in days)

  2. Secondary outcome measures, readmission. [ Time Frame: 1 year postoperatively ]
    Readmission to hospital for treatment of a wound complication (measured in days from primary surgery)

  3. Secondary outcome measures, primary wound healing. [ Time Frame: 1 year postoperatively ]
    Time to primary wound healing and removal of staples, ready for radiation therapy (measured in days from primary surgery)

  4. Secondary outcome measures, deep infection. [ Time Frame: 1 year postoperatively ]
    Deep infection (measured in days from primary surgery, any medical or surgical interventions will be described)

  5. Secondary outcome measures, seroma. [ Time Frame: 1 year postoperatively ]
    Postoperative seroma development (measured in days from primary surgery)

  6. Secondary outcome measures, MSTS. [ Time Frame: 1 year postoperatively ]

    Musculoskeletal Tumor Society Score (MSTS)

    MSTS score is a physician-completed score containing following categories:

    • Pain
    • Function
    • Emotional acceptance
    • Support/Assistive device
    • Walking
    • Gait

    Maximum score is 30 (the value will often be presented in percentage of total).

  7. Secondary outcome measures, TESS. [ Time Frame: 1 year postoperatively ]

    Toronto Extremity Salvage Score (TESS)

    TESS is a self-administrated questionnaire that evaluates physical disability, it consists of 29 questions for upper-extremity and 30 for lower-extremity. Each question is scored from 1-5, where 5 is given if there are no problems. Values will often be presented as a percentage of the total possible amount.

  8. Secondary outcome measures, 5Q-5D. [ Time Frame: 1 year postoperatively ]

    European Quality of Life - 5 Dimensions (EQ-5D)

    EQ-5D is a self-reported questionnaire to evaluate the quality of life, it has 5 dimensions:

    • Mobility
    • Personal hygiene
    • Usual activities
    • Pain
    • Anxiety/depression Each dimension is evaluated with a score of 1-5, where 1 is given to patients without problems. Each answer has a different weight in values and the values for a Danish population will be used in analysis.
