Abstract:
The postoperative outcome of 108 patients with soft tissue sarcoma (STS) of the extremities, the retroperitoneum, or the trunk was investigated retrospectively to identify independent factors for the over all survival and local tumor control. Chi-square single factor analysis and a Cox model were used to identify independent postoperative risk factors. Single factor analysis revealed a significant correlation with negative effect on overall survival for the variables metastasis (p < 0.0001), chemotherapy (p < 0.0009), surgical procedures (0.001), tumor size > 10 cm (p < 0.003), localization (retroperitoneum, trunk) (p < 0.03), and grading (G3/G4) (p < 0.03). Local tumor control was significantly correlated with the variable tumor size > 10 cm (p < 0.01). The Cox model showed a significant negative impact on overall survival for the factors metastasis (p < 0.002), tumor size > 10 cm (p < 0.004), grading (G3/G4) (p < 0.005), and sex (male) (p < 0.008). For local tumor control the variables were age (p < 0.006), and surgical procedures (p < 0.01).
