No significant differences were noted in age, BMI, diabetes, stage, histologic subtype, differentiation, blood biochemical indexes (red blood cells, white blood cells, platelets, hemoglobin (HB), prealbumin, D-dimer (DD)), tumor markers (CA125, HE4, CA199) in the three groups (all p > 0.05) (Table 2). This evidence concerns the gene TTR and neoplasm.
