title: [DNA ploidy and results of first line chemotherapy in ovarian cancer patients].
abstract: OBJECTIVE
  The prognostic significance of DNA ploidy in ovarian cancer patients determined by flow cytometric analysis, in correlation with effectiveness of first line chemotherapy.
  
  
  METHODS
  DNA ploidy by FC was investigated in group of 102 ovarian cancer patients from fresh frozen samples (4 patients was excluded from the study).
  
  
  RESULTS
  Positive answer for first line treatment we notified in 64(62,75%) cases, lack of answer 34 (37,25%) patients. Aneuploidy was more frequent in negative group 31(91,18%), diploid tumours occurred in 3(8.82%) cases. In positive group aneuploid tumours occurred in 29(45,31%) and diploid in 35(54,69%) patients (p<0,001). Median survival in positive group--45 months, in negative group 12 months (p<0,0001). In positive group median survival in patients with aneuploid tumours--31 months, in patients with diploid tumours median survival was not reached (p=0,0102). In negative group DNA ploidy has no impact on survival (p=0,1027)
  
  
  CONCLUSIONS
  1. DNA ploidy determined by flow cytometry is prognostic factor in ovarian cancer patients who answered positively for first line treatment. 2. Aneuploid tumours appear much often then diploid in group of patient who did not answer for first line chemotherapy 3. Patients with diploid tumours have better prognosis. 4. Lack of positive answer for first line treatment is bad prognostic factor.
