Tomita et al. [18] measured preoperative white blood cell counts, hemoglobin (Hb) levels, and platelet counts in 289 consecutive patients with NSCLC who had undergone surgical resection and found that the 5-year survival rates of patients with leukocytosis, anemia, and thrombocytopenia were only 25.0%, which was significantly worse than that of patients with normal blood cell counts (78.23%). The gene discussed is GSTM1; the disease is anemia (phenotype).
