Multivariable analysis revealed that large tumor size (OR, 6.15; 95% confidence interval (CI), 3.34–12.0; p < 0.001), high WBC count (OR, 2.49; 95% CI, 1.40–4.57; p = 0.002), low Hb count (OR, 2.56; 95% CI, 1.36–4.77; p = 0.004), high CRP level (OR, 2.64; 95% CI, 1.51–4.59; p < 0.001), and high LDH level (OR, 4.94; 95% CI, 2.40–10.3; p < 0.001) were significant predictive factors for soft tissue sarcoma (Table 5). This evidence concerns the gene GSTM1 and neoplasm.
