[DNA flow cytometry: perspective prognostic parameters in carcinoma of the uterine cervix].
We studied the relation between the 5-year disease free interval and the flow cytometric DNA content in a group of 55 patients treated by radiation for squamous cell carcinoma of the uterine cervix, stages Ib-IIIb (FIGO). The diploid DNA content was associated with a better prognosis, while prognostically unfavourable tumours tended to be aneuploid. The relation was statistically significant in the whole group (p = 0.016), in stage II disease (p = 0.003) and in the subgroup formed by the combination of stages I and II (p = 0.000). In stage III we did not prove the relation. Analysis of the survival function revealed also a better prognosis of diploid tumours (p = 0.041) in the whole group. The division into clearly diploid and non-diploid tumours seems to be more suitable for evaluation (p = 0.012). The difference between the prognostically favourable and unfavourable groups is expressed more clearly. We consider the flow cytometric DNA content a perspective prognostic parameter in squamous cell carcinoma of the uterine cervix. Its significance is apparent especially in patients treated by radiotherapy, because the size of the tumour cannot be assessed reliably in these cases.
