Abstract
The aim of the retrospective study was to analyze the effect of pioglitazone on the expression of tumor tissue inflammation factor interleukin (IL)-8, macrophage colony-stimulating factor (M-CSF) and vascular endothelial growth factor (VEGF) of type II diabetes in bladder cancer patients. In addition, whether there was a correlation between pioglitazone and the occurrence of male bladder cancer was also investigated. In total, 42 male cases diagnosed with type II diabetes secondary to bladder cancer were selected. Forty male cases, with simplex type II diabetes but not with bladder cancer, served as the control. Tumor biopsy specimens were collected to detect the expression levels of IL-8, M-CSF and VEGF. The results showed that the expression of IL-8, M-CSF and VEGF of the simplex diabetes group was significantly lower than that of the secondary to tumor group (P<0.05). The comparison of the two groups in terms of daily dose and time of oral pioglitazone, duration of diabetes, average fasting blood sugar and glycated hemoglobin levels, was not statistically significant. Multivariable logistic regression analysis revealed that the expression levels of IL-8, M-CSF and VEGF were independent risk factors for the occurrence of bladder cancer (P<0.05), but were not associated with daily dose and time of oral pioglitazone (P>0.05). In conclusion, oral pioglitazone may not increase the risk of type II diabetes patients with bladder cancer. However, the occurrence of bladder cancer be associated with the increasing expression levels of IL-8, M-CSF and VEGF.
