Outcome of Surgery as Part of Palliative Care of Patients with Symptomatic Advanced or Metastatic Extra-Abdominal...

The modern multimodal treatment of malignant tumors has increased disease-specific survival and decreased the burden of tumor-associated complications. The main focus of palliative surgery is not based primarily on quantitative success parameters of tumor response but is instead mainly on the question of quality of life.

The current study was conducted to analyze the clinical and oncological outcomes of palliative patients with soft tissue sarcoma.

Of 309 patients with extra-abdominal high-grade soft tissue sarcoma treated between August 2012 and December 2014, our retrospective analysis revealed 33 palliative patients for this study. All patients were evaluated and managed by a multidisciplinary team with expertise and experience in sarcoma treatment. The survival analysis was made using the Kaplan-Meier method.

The main sarcoma symptoms were pain (27.3%) and ulcerated tumors or shortly before ulceration (24.2%). Thirteen patients (39.4%) were operated on with negative margins, 15 (45.5%) with positive margins, 2 with tumor debulking (6.1%), and 3 patients (9.1%) were treated only with palliative hyperthermic isolated limb perfusion. Ten pedicle flaps were performed after sarcoma resection. The median operation time was 85 minutes (range, 37-216 minutes). The median hospitalization stay was 9.5 days (range, 3-27 days). No patients died during hospitalization. Twelve-month disease-free survival was 48.5% (95% confidence interval: 45.4-51.6).

Palliative surgery of metastatic or advanced soft tissue sarcoma can improve the wound care and quality of life. Closed noninfected wounds enable further treatment options, such as chemotherapy, immunotherapy, and radiotherapy. This surgery should be considered during the discussion on interdisciplinary tumor boards.
