Prevalence of diabetes in a cancer population in a Malaga hospital.

BACKGROUND

There are multiple risk factors for cancer, including obesity, sedentary lifestyle, diabetes (DM). Hormon Insulin is a growth factor that promotes cellular differentiation.

AIMS

The aim of our study is to observe impaired glycaemia in cancer population compared with control.

METHODS

We studied the prevalence of diabetes (DM) and impaired fasting glycaemia (IFG) in 374 patients with different types of cancer before treatment, by medical records in a Malaga hospital (Spain). We compared the prevalence of basal hyperglycaemia in these patients with general population, within an age range and by gender.

RESULTS AND DISCUSSION

The prevalence of diabetes was 32.35% in our cancer patients. The comparison depends of age range, and by gender prevalence was: 45-54 years, DM: 40.91% in men cases, versus (vs.) 14.5% in men control (p = 0.005). 55-64 years, IFG: 23.08% in women cases, vs. 5.9% in women control (p = 0.001). 65-74 years, DM: 47.13% in men cases, vs. 25.4% in men control (p = 0.000), and IFG: 23.81% in women cases, vs. 9.5% in women control (p = 0.019). We found a higher prevalence of diabetes in specific types of cancer such as prostate (p < 0.005). Moreover, men had a higher prevalence of diabetes or less diabetes control than women in our cancer sample.

CONCLUSIONS

We recommend an OGTT (oral glucose tolerance test) for better diagnosis of possible DM in patients with cancer, and an appropriate treatment. It may be an independent risk factor for cancer to have decreased insulin activity, or DM.
