Correlation between tumor markers and type 2 diabetes mellitus complications and their related influencing factors

This study aims to investigate the correlation between type 2 diabetes mellitus (T2DM) and the tumor markers/biochemical parameters of patients, as well as the related factors leading to complications.

A total of 150 T2DM patients in our hospital were included as the research group, and 80 healthy persons were matched in the normal control group. The levels of tumor markers (CA199, CEA, CA153, CA125, AFP) and body mass index (BMI), waist-to-hip ratio (WHR), blood pressure (BP), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), urine microalbumin (M-ALB), and triglyceride (TG) in the two groups were determined. Based on the complications status of T2DM patients, the patients were further divided into a complication-free group (patients with simple diabetes) and complication group. Univariate analysis was performed between patients with and without complications.

The levels of serum CA199, CEA, and CA125 in the study group were significantly higher than those in the normal control group (all P<0.0001), and the levels of BMI, WHR, systolic BP (SBP), diastolic BP (DBP), FPG, HbA1c, M-ALB, and TG in the study group were significantly higher than those in the control group (all P<0.05). Tumor markers CA199, CEA, and CA125 were positively correlated with BMI, WHR, BP, FPG, HbA1c, M-ALB, and TG. Smoking, family history of diabetes, combined hypertension, hyperlipemia, course of disease, CA199, CEA, CA153, CA125, AFP, SBP, DBP, FPG, HbA1c, M-ALB, and TG were the influencing factors of complications in T2DM patients.

Relevant indicators of T2DM patients with complications should be fully evaluated clinically, and long-term follow-up observation should be conducted, so as to reduce the occurrence of complications.
