[Experience in cancer of the uterine cervix treated with surgery--an analysis of 820 cases].

From 1962 to November 1985, 1000 cases of cervical cancer were treated surgically, of whom 820 (37 Stage 0, 371 Stage I, 399 Stage II, 10 Stage III and 3 Stage IV lesions) had been operated before 1982. In the 820 cases, squamous cell cancer comprised 90.5%, adenocarcinoma 8.8% and adenoacanthoma or adenosquamous cancer 0.7%. Pelvic lymph node metastasis rate was 8.9% and 24.1% in Stages I and II. The obturator region was the most vulnerable to metastasis. The 5-year survival rate was 86.7% in 173 cases of infiltrative cancer treated during 1978-1982. The 10-year survival rate was 85.25% (520/610) in the infiltrative cancer, 95.9% in Stage I and 75.3% in Stage II. Two cases with Stage IV without pelvic lymph node metastasis treated with surgery have survived for over 10 years. All thirty-seven cases of cervical cancer in situ treated with surgery are still alive. Pelvic lymph node metastasis is the major factor influencing operation and survival.
