    Abstract:
    Apart from the stage of the tumour and the method of surgical approach, factors of special importance in prognosis are the histological type of tumour and the histological and cytological grading of malignant ovarian tumours. To supplement the prognostic factors, DNA flow cytometry has recently been introduced to determine parameters of cell kinetics such as ploidy (the status of the chromosome set in the karyotype) and the number of DNA-synthesized cells. In the present study 81 patients with a malignant tumour of the ovary--most of them classified according to FIGO stage III/IV--were followed up for 12 to 56 months (FIGO = Fédération Internationale de Gynécologie et d'Obstétrique). The survival times are correlated with clinical, morphological and cell kinetics data. The FIGO stage is the most important prognostic factor. None of the patients in stage I/II (FIGO) died during the study period, whereas of 63 women in stage III/IV (FIGO) 41 have already died. The histological tumour type is not so significant for prognosis. The survival curves show that of all the examined prognostic factors in stage III/IV (FIGO) the S-phase proportion (i.e. the proportion of DNA-synthesized cells) is the most important one. Statistically significant differences are also seen in ploidy and in grading. However, in histological grading of tumours the differences are noticeable only in grading G 1 and in grading G 3. G 2 carcinomas--which, by the way, account for one-third of all carcinomas-are a kind of collecting "pool" of tumours whose prognosis cannot be assessed.(ABSTRACT TRUNCATED AT 250 WORDS)
