[Renal carcinoma: active detection in regular check-ups]

To improve early diagnosis of renal carcinoma (RC) in the course of check-ups.

Regular checkups performed in 1980-1999 detected 715 cases of renal carcinoma. Among the patients were 452 male (60.2%) and 263 female (39.8%) patients. Mean age was 66 years. Screening methods for healthy examinees and risk group examinees, RC incidence rate, 1 year lethality and survival were assessed.

Mean RC incidence rate in men was 80.9, in women 34.9 per 100,000. Early diagnosis of RC stage I and II made up 58.4 in men and 59.4% in women. Significantly more patients with RC stage I and II were diagnosed at checkup than among those seeking medical advice. 5-year corrected survival in males was 80%, 10-year survival--74%, in females--84 and 80%, respectively.

Check-up raised early diagnosis of RC stage I and II up to 82.3%. This, in its turn, improved survival of RC patients.
