对４１例卵巢恶性肿瘤，３０例卵巢良性肿瘤进行外周血Ｔ细胞亚群、ＮＫ细胞活性检测，并与３０例健康者对照。结果：①恶性组Ｔ４、Ｔ４／Ｔ８比值明显低于良性组及对照组（Ｐ＜０．０５），后两者之间无明显差异。肿瘤细胞减灭术后２周，水平上升，较术前有显著差异（Ｐ＜０．０５）。②恶性组ＮＫ细胞活性明显低于良性组及对照组。随病情进展进一步降低，临床Ⅲ～Ⅳ期明显低于Ⅰ～Ⅱ期（Ｐ＜０．０５）。提示检测上述指标具有重要临床意义。
In 41 cases of ovarian cancer and 30 cases of benign ovarian tumors, T lymphocyte subsets and NK cell activity were detected in peripheral blood and 30 healthy controls. Results: ① The ratio of T4, T4 / T8 in malignant group was significantly lower than that in benign group and control group (P <0.05), but there was no significant difference between the two groups. Tumor cytoreductive surgery two weeks after the rise, compared with the preoperative significant difference (P <0.05). The malignant group NK cell activity was significantly lower than the benign group and the control group. With the progression of the disease to further reduce the clinical stage Ⅲ ~ Ⅳ was significantly lower than Ⅰ ~ Ⅱ (P <0.05). Tip detection of the above indicators of great clinical significance.
