[Has echography modified the occurrence of kidney carcinoma? Considerations on 316 cases].
An analysis of 316 renal carcinomas over an 11-year period has shown an increase in the incidence of tumors per year, together with a progressive decrease in the size of the lesions at the time of diagnosis. This effect occurred especially after the introduction of renal ultrasonography in diagnostic practice. The tumor size is an important prognostic factor, because the 5-year survival rate was 80% for tumors less than 5 cm and 30% for tumors greater than 10 cm. Ultrasonography might thus represent a screening method for renal carcinoma in patients over 50 years of age, if it were possible to define risk groups.
