Anemia (OR 1.56, 95%CI 1.05–2.31), leukocytopenia (OR 3.45, 95%CI 1.15–10.39), leukocytosis (OR 2.38, 95%CI 1.62–3.50), thrombocytopenia (OR 3.47, 95%CI 1.77–6.81), thrombocytosis (OR 1.89, 95%CI 1.16–3.07) and elevated ESR (OR 1.82, 95%CI1.05–3.15), CRP (OR 2.70, 95%CI 1.84–3.97) and LDH (OR 1.90, 95%CI 1.30–2.79) were significantly associated with a cancer diagnosis in a univariate analysis (Table 3). This evidence concerns the gene ESR1 and thrombocytosis disease.
