The authors describe the frequency, incidence, number of deaths and mortality from malignant tumours of the uterine corpus in the Czech Republic in 1961-1988. The mean incidence of 13.06 during the five-year period 1961-1965 rose to a mean incidence of 25.12 during the five-year period 1984-1988, while during this period a paradoxical decline of the mortality from 9.00 to 6.7 occurred. This implies a decline of the lethality during 1961-1965 from 76.56% to 28.98%, i.e. to 37.85% of the original value. The reasons of the decline in lethality may be earlier detection of the disease and possibly a rise in the incidence of less aggressive forms of hormone-dependent carcinomas only, because therapy did not change essentially during the mentioned period.
