GSTM1 and thrombocytosis disease: Conversely, the median OS was significantly different according to ECOG-PS (0 vs. 1 vs. ≥2; 30.71 months vs. 10.95 months vs. 2.96 months, p < 0.001, Figure 2), Hb ≥12 g/dL vs. <12 g/dL (30.71 vs. 8.42 months, HR = 0.24, 95% CI 0.10–0.44, p < 0.001, Figure 2), thrombocytosis (15.52 vs. 10.95 months, HR = 0.42, 95% CI 0.09–0.90, p = 0.032, Figure 2) and hypercalcemia (11.08 vs. 4.37 months, HR = 0.32, 95% CI 0.04–0.60, p = 0.008, Figure 2).
