There were no significant differences between the PH + DXMS group and the PH group in terms of gender, age, body mass index (BMI), history of smoking, history of underlying diseases, Eastern Cooperative Oncology Group (ECOG) score, tumor-node-metastasis (TNM) stage, liver function, duration of hospitalization, white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb), or platelets (PLT) (all p > 0.05). This evidence concerns the gene GSTM1 and neoplasm.
