OVARIAN METASTASES IN STAGE-IB CARCINOMA OF THE CERVIX - A GYNECOLOGIC ONCOLOGY GROUP-STUDY

Surgical and pathologic findings at laparotomy for radical hysterectomy in 990 patients with clinical stage IB caricimona of the cervix were analyzed to determine the frequency of metastases to the ovary. Ovarian spread was identified in 4 of 770 (0.5%) patients with squamous carcinoma and 2 of 121 (1.7%) with adenocarinoma. No patients with adenospuamous carcinoma (n = 82) or other histologic types (n = 17) had ovarian metasteses. Although the frequency of metastases was greater among patients with adenocarcinoma, this was not statistically significant (p = 0.19, Fisher's exact test). All 6 patients with ovarian metastases had other evidence of extracervical disease. Three underwent radical hysterectomy and bilateral salpingo-oophorectomy. Of these, one patient received extended field radiotherapy and died of diseas 18 months after diagnosis. Two patients, one treated with combination chemotherapy and one with no adjunctive therapy, are alive without evidence of disease at 59 and 62 months, respectively. Three patients underwent exploratory laparotomy with salpingo-oophorectomy and lymphadenectomy without hysterectomy. All three died of disease at 2, 3, and 30 months; the first and last patient received adjunctive radiotherapy. Not all patients underwent oophorectomy. Of 347 patients with at least unilateral ovarian preservation, no postoperative pelvic radiotherapy, and no gross extracervical disease or metastasis to the paraaortic nodes, pelvic recurrence devoloped in 16. There was no excess of pelvic recurrences in patients with adenocarcinoma (0/41) or adenoswuamous carcinoma (1/29, 3.4%) when compared with those with swuamous carcinoma (15/270, 5.6). This suggest no excess of occult ovarian metastases in nonswuamous tumors of the cervix. There is no evidence in these data of an increased risk of ovarian preservation in patients with stage IB carcinoma of the cervix no gross extracervical disease.
