Aim. The aim of the study was to assess the rate of neuroendocrine malignancies in the gastrointestinal tract, other malignancies and mitotic processes, in type-2 diabetic patients. In particular, we tested the hypothesis that a poor metabolic control is associated with a higher rate of neoplasms and other co-morbid conditions, such as hypertension and peripheral neuropathy.
Methods. Forty-one consecutive asymptomatic type-2 diabetic outpatients were followed for 8 years and clustered in 2 groups, according to disease duration, insulin need, and dose of oral antidiabetic agents. Physical examination, blood pressure measurements, and neurophysiologic studies were serially performed during the follow-up. In each subject, a general biochemistry was performed, aspecific and specific antigens (α-fetoprotein, carcinoembrionic-antigen and prostate specific antigen PSA and F-PSA) levels were measured, and invasive and non-invasive procedures were carried out, when necessary, to detect a neoplastic process.
Results. The rate of malignancies and mitotic processes was significantly higher in patients with longer duration of disease and poor diabetes control (72% vs 13%, p=0.02). Hypertension (83% vs 54%) and peripheral neuropathy (67% vs 21%) were also more common in this group.
Conclusion. These data, although obtained in a relatively small population, highlight the importance of closely monitoring type-2 diabetic patients with poor diabetes control as this might be associated with the presence of malignancy or other co-morbid conditions. This may be particularly true when the poor glycemic control is characterised by a sudden onset or significant worsening despite streghtening of antidiabetic therapy.
