Resumo: | Objective: To assess the cellular DNA status of epithelial ovarian cancer cells for clinical stage identification and its effect on survival. Methods: Sixty-twopatients treated by primary surgery and six courses of platinum-based chemotherapy were enrolled. The surgical stage was analyzed in correlation with DNA ploidy, S-phase fraction and DNA index. DNA analysis was performed via image cytometry. Results: From the 62 cases,38 were International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d’Obstétrique, FIGO) stage I and II, 24 – stage III and IV. In the DNA histograms obtained, the DNA index ranged from 0.85 to 3.02. Sixteen were classified as diploid and 46 as aneuploid (18 multiploid). S-phase fraction ranged from 9.8 to 51%. The aneuploid cells with DNA content above 5C ranged from 0.0 to 77.2%. Patients diagnosed with FIGO III and IV (vs. I and II) were 3.3 times more likely to die. Only in FIGO stage I and II the survival differed significantly for the different groups of ploidy. The risk of death for the multiploid (vs. diploid) group is 6.4 times and for aneuploid (vs. diploid) 2.3 times. Overall survival was better in the group with low DNA index. The low percentage compared with a high percentage of 5C cells ploidy groups showed association with mortality. The death hazard for the S-phase >33 median group is 4.9 times the hazard in relation to the S-phase <33. Conclusions: DNA ploidy, DNA index, S-phase, and 5C cells are important prognosticators for epithelial ovarian cancer mainly in early stages. |

Metoda: Do badania zakwalifikowano 62 pacjentki leczone operacyjnie i za pomocą chemioterapii opartej na platynie (6 kursów). Stopień zaawansowania klinicznego nowotworu analizowano w odniesieniu do ploidalności DNA, frakcji fazy S oraz indeksu DNA. Analizę DNA przeprowadzono z zastosowaniem cytometrii obrazowej. Wyniki: Spośród 62 pacjentek 38 zakwalifikowano jako stopień zaawansowania I i II, natomiast 24 – jako stopień III i IV wg FIGO (International Federation of Gynecology and Obstetrics). W otrzymanych histogramach DNA indeks DNA wynosił 0,85–3,02. Szesnaście przypadków raka zaklasyfikowano jako diploidalne, natomiast 46 – jako aneuploidalne (18 multiploidalnych). Frakcja fazy S mieściła się w przedziale 9,8–51%. Odsetek komórek aneuploidalnych z zawartością DNA powyżej poziomu 5C wynosił 0,0–77,2%. Ryzyko śmierci było 3,3-krotnie większe w przypadku pacjentek z chorobą w stopniu zaawansowania FIGO III i IV (w porównaniu z I i II). Jedynie w przypadku stopni zaawansowania FIGO I i II odnotowano istotnie różnice w przeżywalności między poszczególnymi grupami ploidalności. Ryzyko śmierci było 6,4-krotnie większe w przypadku multiploidalności i 2,3-krotnie większe w przypadku aneuploidalności (w porównaniu z diploidalnością). Dłuższe przeżycie ogólne odnotowano w grupie o niskim indeksie DNA. Wykazano związek między niskim odsetkiem komórek 5C, w porównaniu z wysokim odsetkiem tych komórek w grupach poliploidalnych, a śmiertelnością. Ryzyko śmierci było 4,9-krotnie większe w grupie z medianą liczby komórek w fazie S >33 w porównaniu z medianą liczby komórek w fazie S <33. Wnioski: Ploidalność DNA, indeks DNA, faza S oraz obecność komórek 5C to ważne czynniki prognostyczne u pacjentek z nabłonkowym rakiem jajnika, głównie we wczesnym stadium.Veritati - Repositório Institucional da Universidade Católica PortuguesaTomé, AntónioLeal, IrenePalmeiras, CarlosMatos, EduardaAmado, JoãoAbreu, MiguelLopes, Carlos2018-09-17T16:35:18Z20182018-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.14/25705engTomé, A., Leal, I., Palmeiras, C., Matos, E., Amado, J,, Abreu, M,, ...
