ABSTRACT
OBJECTIVE: To explore the relationship between Type 2 diabetes and primary liver cancer. MATERIALS AND METHODS: In the period from December 2008 to December 2014, all blood sugar data of patients in our hospital was collected, and the total number is 18213. Except for repeatedly hospitalized diabetic person, newborn stress status, or venous transfusion blood glucose, gestational diabetes, etc., By retrieving the medical record information of patients in the hospital, and using telephone or letter follow-up the patients, we collected 127 people with type 1 diabetes and found no liver cancer patients; Type 2 diabetes, 10,794 cases of patient information, 59 with primary liver cancer. For data analysis, Stata11.0 ratio was used as the main analysis indicators, using Chi‑square test and statistical analysis. RESULTS: About 10,794 Type 2 diabetes cases with 59 primary liver cancer, the incidence is 54.66/10,000, men liver cancer incidence (92.78/10,000) than women (27.13/10,000), with significant difference (χ2 = 26.621, P < 0.001). As the growth of the age, the possibility of liver cancer in patients with diabetes increased significantly (χ2 = 19.961, P = 0.001). The rate was highest for 50–60‑year‑old men, and the women at age 70, and older incidence is highest. Irrespective of men or women with diabetes as the growth of the age, the possibility of liver cancer had significantly increased (P = 0.001, P = 0.002). Hepatitis B or hepatitis C incidence was 2.94%, but diabetes incidence of hepatitis men (3.98%) and women (2.01%) did not find significant differences (χ2 = 0.3361, P = 0.562). Three hundred and seventeen cases of Type 2 diabetes with hepatitis, the incidence of primary liver cancer was 11.67%, the liver cancer incidence of diabetes patients with hepatitis men (17.78%) than women (3.97%), with significant difference (χ2 = 37.429, P < 0.001). With the growth of age, the overall risk of getting liver cancer (χ2=15.023, P = 0.01) of diabetes and hepatitis patients is significantly increased, and with the growth of age, the risk of getting liver cancer of male patients showed significant (P < 0.05), but not the female patients. Without merge hepatitis, the morbility of primary liver cancer in 10477 cases of type2 diabetes incidence is 0.21%, the liver cancer incidence men (0.34%) than women (0.11%), with significant difference (χ2 = 6.471, P = 0.011).As the growth of age, the overall risk of getting liver cancer of diabetes patients without hepatits is significantly increased (χ2 =15.612, P = 0.008) ,and the risk of getting liver cancer of male patients showed significant (P < 0.05) as the growth of the age, but not the female patients. Diabetic persons according to the illness time can be divided into 0–5 years, 5–10 years, 10–20 years, and over 20 years of four stages, including 5–10 years and 10–20 years is liver cancer patients with diabetes incidence peak, male diabetic hepatitis in patients with liver cancer incidence than women, with significant difference (χ2 = 22.757, P < 0.001). The possibility of liver cancer in patients with diabetes increased significantly (χ2 = 15.023, P = 0.01) for longer duration of illness, but only the male patients with liver cancer incidence showed significant difference with longer duration of illness, women showed no significance. CONCLUSION: Diabetes was associated with the primary liver cancer, most likely is one of the causes of primary liver cancer.
