用物理或化学方法将新鲜或石蜡包埋的瘤组织制成单细胞悬液,用流式细胞仪测定其DNA 倍体状态。在卵巢肿瘤,倍体状态是一个客观、稳定的指标。DNA 异倍体多见于组织学分化差、临床晚期、有腹水存在、绝经后及术后残余瘤较大的病人,其生存期明显短于二倍体肿瘤病人,DNA 倍体可做为一个预测该肿瘤预后、指导合理化疗的可靠指标。 The fresh or paraffin-embedded tumor tissue was made into single cell suspension by physical or chemical methods, and the DNA ploidy state was determined by flow cytometry. In ovarian tumors, ploidy status is an objective and stable indicator. DNA aneuploidy more common in poorly differentiated histology, late clinical stage, the presence of ascites, postmenopausal and postoperative residual tumor larger patients, the survival was significantly shorter than the diploid tumor patients, DNA ploidy can be used as a prediction The prognosis of the tumor, a reliable indicator of rational chemotherapy.
