Objective: The incidence and mortality of malignant tumours of the uterine cervix, uterine body and ovary are analysed. Design: Retrospective study. Setting: Department of Obstetrics and Gynecology, Medical Faculty and Faculty Hospital, Charles University, Plzeo. Methods: Analysis of relevant dates from the National Oncological Registry 1986 - 1995. Results: The incidence of the cervical carcinoma oscilated around 22 (22.7 - 21.6), the mortality slightly decreased (9.6 - 8.4). The incidence of the corpus carcinoma rose again (25.9 - 28.9), its mortality declined (7.4 - 6.9). The incidence of malignant ovarian tumours significantly increased (16.3 - 23.4), the mortality became slightly higher (14.8 - 16.2). The incidence of the ovarian carcinoma got ahead the incidence of the cervical carcinoma (23.4 : 21.6) and it occupied the second place after the corpus carcinoma. Conclusions: It is necessary to screen systematicaly gynecological malignant tumours and concen- trate its treatment to specialized centers. Correct reports of these tumours and their precise staging is needed, too.
