title: [Registry-based analysis of cancer and diabetes combination: prevalence and features].
abstract: Neoplasia was established in 5.4% out of 15,813 patients with diabetes mellitus registered at the City Population-Based Cancer Register and Territorial Diabetic Center, St. Petersburg. Gender-unrelated decreasing order of tumor sites was as follows: breast, skin, uterus, colon and stomach. Broncho-pulmonary and gastric cancer incidence in male patients with diabetes was higher than in females (3.5 and 2.2 times, respectively). The relationship was reversed with thyroid cancer and skin melanoma (4.4 and 2.3 times, respectively). In patients with type 1 diabetes mellitus (10.3%), the cancer incidence pattern differed significantly from that in the whole diabetes-associated cohort of cancer patients: the former tended to involve such sites as pancreas, urinary bladder, stomach, cervix uteri, lung and skin. Data on age at diagnosis of cancer or diabetes, insulin therapy intensity and body mass were evaluated. The value of timely screening for both cancer and diabetes mellitus in such cohorts was confirmed.
