Epidemiological evaluation of the efficiency of treatment of pre-invasive cervical cancer in Warsaw, 1969-1988.

An analysis of 2,281 cases of pre-invasive cervical cancer registered in Warsaw Cancer Registry during the years 1969-1988, showed that the rate of cervical cancers detected at the pre-invasive stage declined from 46.8% in 1970, to 26.8% in 1988. New cases of this cancer were diagnosed mainly in the age group up to 49 years of age (86.1%). Conservative treatment was applied relatively rarely (in 43.0% of cases) while the uterus with adnexes were removed fairly frequently (26.0%). The results of treatment were good (100.0% of 5-year survivals.). The 5-year survivals seem not to differ in relation to any particular treatment method used.
