The results of treatment of microinvasive carcinoma (stage iA) of the uterine cervix by means of simple and extended hysterectomy.
At the Department of Obstetrics and Gynecology of Tohoku University, radical hysterectomy with pelvic lymphadenectomy had been performed on patients with microinvasive carcinoma of the uterine cervix before 1966. Investigation of lymph nodes of 90 patients treated in this manner has shown no lymph node metastasis of tumor cells in any of them. Since 1967, microinvasive carcinoma has been treated as a matter of principle by extended hysterectomy without lymphadenectomy. From that time until 1974, 119 cases of microinvasive carcinoma have been treated by extended hysterectomy and 69 such cases by simple hysterectomy. The 5-year relative survival rate was 0.989 for extended hysterectomy patients and 1.008 for simple hysterectomy patients. Together, a 5-year relative survival rate of 0.992 was obtained.
