Ovarian metastasis in stage IB and II cervical adenocarcinoma.

We performed the present study to identify those patients with adenocarcinoma of the cervix in whom ovarian preservation might be acceptable. Between January 1971 and December 1996, 82 patients with International Federation of Gynecology and Obstetrics stage IB and II cervical adenocarcinoma and adenosquamous carcinoma, treated by radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic node dissection, were identified. The mean age of the patients was 44.6 years (range 27-72). The incidence of ovarian metastasis was more frequent in stage II (19.0%) than in stage IB disease (2.5%), in which only 1 patient with apparent extrauterine disease at laparotomy had an ovarian metastasis. No patients with up to inner two-thirds of stromal invasion had ovarian metastasis; however, 5 of 24 patients with outer one-third stromal invasion (20.8%) and 4 of 20 with parametrial invasion (20.0%) had ovarian metastasis. A significantly higher incidence of ovarian metastasis was also observed in 5 of 20 cases with lymph node metastasis (25.0%) than in 4 of 62 patients without lymph node metastasis (6.5%). Multivariate analysis, however, found only deep stromal invasion to be an independent risk factor for ovarian metastasis. Although it would be reasonable to conserve normal-appearing ovaries in young women undergoing radical hysterectomy for treatment of stage IB cervical adenocarcinoma and adenosquamous carcinoma, gross intraoperative inspection of the radical hysterectomy specimen may identify deep cervical invasion or extrauterine spread in those who are at increased risk of ovarian metastases.

A multivariate analysis of blood vessel and lymph vessel invasion as predictors of ovarian and lymph node metastases in patients with cervical carcinoma.

To the authors' knowledge there are few available data regarding the influence of lymphovascular space invasion, which has been examined separately as two components (lymphatic vessel invasion [LVI] and blood vessel invasion [BVI]), in the metastasis of cervical carcinoma. LVI and BVI, which include capillary vessel invasion, were reviewed retrospectively based on the histopathologic slides of 239 women with cervical carcinoma who were treated with radical hysterectomy. The correlation between lymph node and/or ovarian metastases and LVI, BVI, and other histopathologic factors was investigated by multiple logistic regression analysis. The influence of LVI and BVI on survival was examined by Cox regression analysis. The rate of incidence of LVI was higher than that of BVI in all stages of cervical carcinoma (P < 0.0001 for International Federation of Gynecology and Obstetrics Stage IB and Stage II disease and P < 0.05 for Stage III disease). The incidence rate of BVI increased as LVI became more prominent and there was a significant correlation between the two findings (P < 0.0001). BVI was more frequent in adenocarcinoma/adenosquamous carcinoma than in squamous cell carcinoma (P < 0.05). LVI (P < 0.0001) and parametrial invasion (P < 0.0001) were significantly related to lymph node metastasis on multivariate analysis. Conversely, BVI (P < 0.05) and parametrial invasion (P < 0.0025), as well as adenocarcinoma or adenosquamous carcinoma (P < 0.0005), were significantly related to ovarian metastasis on multivariate analysis. With regard to the prognostic significance of these components, it was found that BVI (hazards ratio [HR] = 2.0), ovarian metastasis (HR = 6.5), and lymph node metastasis (HR = 5.5) were significantly related to a poor prognosis in women with cervical carcinoma. Ovarian metastasis may occur via hematogenous spread of cervical carcinoma. The results of the current study suggest that BVI, including capillary vessels, that is diagnosed separately from LVI using hematoxylin and eosin stained sections may be an important prognostic factor for patients with cervical carcinoma.
