Abstract:

Objective To explore the risk of incidence of over all cancer and site-specific cancers in patients with pre-diabetes. Methods From 2011 to 2018, 31 568 pre-diabetes patients aged 20 years and above who were newly diagnosed and registered in the community diabetes management information system of Shanghai were used as the unique identifier to link data with the Shanghai Malignant Tumor Registration System to obtain their malignant tumor incidence, to calculate the incidence of all causes and the top ten malignant tumors of pre-diabetes patients of different sexes and ages standardized incidence rate and standardized incidence ratio (SIR). Results The crude incidence rate of all cause tumors in pre-diabetes patients was 868.1/100 000 person years, 1 099.48/100 000 person years for male and 729.19/100 000 person years for female. The standardized incidence rate was 567.49/100 000 person years, 512.15/100 000 person years for male and 597.91/100 000 person years for female. The SIR of all cause tumors was 0.97, 0.99 for male and 0.99 for female, respectively. The relative incidence risk of all cause tumors in pre-diabetes patients gradually decreased with age, and the SIR of pre-diabetes patients in the 20-49, 50-59, 60-69, 70-79 and ≥80 age groups was 3.04, 1.21, 1.00, 0.92 and 0.66, respectively. The incidence risk of thyroid cancer in the 20-49 and 50-59 year old pre-diabetes patients were 4.85 and 1.86 times higher than that of the total population of the same age, respectively, and the incidence risk of thyroid cancer in the 20-49 and 50-59 year old female pre-diabetes patients were 4.46 and 1.53 times higher than that of the total population of the same sex and age, respectively. The risk of bladder cancer and kidney cancer in male under 50 years of age with pre-diabetes were 36.34 and 13.49 times higher than that in the total population of the same sex and age, respectively. The risk of prostate cancer in male aged 60 to 69 years in pre-diabetes was 2.66 times higher than that in total population of the same sex and age. Conclusions The risk of all-cause cancer in pre-diabetes patients was not significantly higher than that in the total population. The relative risk of all-cause cancer and site-specific cancers of the population decreased with age. It is necessary to increase the screening of specific cancer species in specific gender and age groups. For newly diagnosed pre-diabetes patients over 80 years old, it is recommended to reevaluate the risk of disease diagnosis and prognosis.
