title: Influence of cellular DNA content on survival in advanced ovarian cancer.
abstract: Tumor cellular DNA content was measured by flow cytometry in 91 patients with advanced ovarian cancer, using a new and simple technique which allows archival paraffin-embedded tissue to be studied; 69% of the tumors were aneuploid, and 31% were diploid. Tumor ploidy was shown by multivariate Cox model analysis to be an independent prognostic variable and the major determinant of survival. Patients with diploid tumors survived significantly longer than did those with aneuploid tumors (p much less than 0.0001; X2 = 25.44; d.f. = 1).
