[Pathological study of ovarian metastasis in cervical cancer]

During the period from 1977 to 1986, 860 patients with cervical cancer were examined ovarian metastasis in our department. Four hundred and seventy seven patients of stage 0 and Ia were treated by a simple hysterectomy without oophorectomy. Follow-up examinations on these stages revealed no recurrence in the ovaries and 5 year survival rate is 100%(239/239). In 383 patients with invasive carcinoma in stage Ib to stage III, who were treated by radical hysterectomy, histological examinations were performed to detect ovarian metastasis. In invasive cases of epidermoid carcinoma(stage Ib to stage III), no ovarian metastases were detected, despite discovery of metastases to the pelvic lymph node in 22.3% of the cases. Conversely, in the cases of cervical adenocarcinoma(pure adenocarcinoma and mixed carcinoma), 9 of 74 cases(12.2%) showed ovarian metastases even in early histologic stages. It is noteworthy that seven of nine cases had no lymph node metastasis. Only endocervical type had ovarian metastasis in pure adenocarcinoma. In mixed carcinoma, metastatic lesion of ovary is adenocarcinoma.
