title: Pelvic lymph node metastasis of uterine cervical cancer.
abstract: The state of pelvic lymph node metastasis was observed in 627 cases of Okabayashi's radical hysterectomy performed from 1950 to 1984 of which 589 cases with a known 5-year survival rate were examined according to their relationship to prognosis. The incidence of lymph node metastasis was 29.7%, becoming progressively higher with succeeding clinical stages. The metastasis rates according to site were 6.9% hypogastric nodes, 4.9% obturator nodes, 4.4% iliac nodes, and 25.0% parametrial nodes. Among the factors considered in the postoperative classification, lymph node metastasis demonstrated high values in cervical infiltration cancer, positive parametrial infiltration, positive vaginal invasion, and infiltration into the uterine body and L type of CPL classification. The 5-year survival rate was 83.0% in negative cases of pelvic lymph node metastasis, while in positive cases, it was as poor as 45.8%. Considering the relationship of various factors, it is shown that the presence of lymph node metastasis has a great effect on prognosis.
