A retrospective study of 27 ovarian tumors of low malignant potential.
Eur J Gynaecol Oncol. 2002; 23(5):415-8.EJ

Abstract

INTRODUCTION

This study was undertaken to retrospectively review the fertility-sparing surgical treatment and long-term outcome of 27 patients with ovarian tumors of low malignant potential treated at the 1st Department of Obstetrics and Gynecology of Semmelweis University Faculty of Medicine between 1990 and 2000.

MATERIALS AND METHODS

Between 1990 and 2000, 163 patients with epithelial ovarian tumors were diagnosed and treated. Of these, 27 patients were diagnosed as having low malignant potential (LMP) ovarian tumors. The authors evalutated the effect of histopathologic parameters (histologic type, grade of nuclear atypia, tumor size and tumor growth on the ovarian surface) and clinical parameters (age at diagnosis, stage of disease, and treatment modalities) on prognosis in this group of patients with a long observation time. We reviewed our experience to assess the safety of conservative surgical management of patients younger than age 40 with early stage disease, and to determine the long-term outcome of low malignant potential ovarian tumors. Medical records were reviewed on all 27 patients to determine age, gravidity, size of tumor, bilaterality, sites of extraovarian involvement, stage of disease and the operative procedure. Follow-up information was obtained from hospital records, and in some cases, by direct patient contact. Statistical comparisions were made by the chi2 test.

RESULTS

The incidence of LMP tumors in our patient population was 16.5%. The patients ranged in age from 15 to 82 years (median, 45 years). The lesions were staged according to FIGO. The stage distribution was Stage IA in 20 patients, Stage IB in one patient, Stage IC in one patient, Stage IIA in one patient, Stage IIB in one patient, Stage IIC in one patient and Stage IIIA in two patients. The ovarian tumors ranged in size from 3 to 19 cm (median 9 cm) and 15% of the tumors were bilateral. All patients with LMP ovarian tumors were treated with primary surgery; those who were older than 40 (14 patients) were treated with total trans-abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH and BSO), while patients younger than 40 with early stage disease (12 patients) who wished to retain their fertility potential were treated with fertility-sparing surgery, namely unilateral salpingo-oophorectomy (USO). One patient who was younger than 40 with a Stage IIIA LMP ovarian tumor was also treated with TAH and BSO. Follow-up information was available for all 27 patients with LMP ovarian tumors. Only those patients with a minimum of two years of follow-up were included. Follow-up information from two to ten years (median, 6 years; mean, 6.5 years) revealed that all 27 patients were alive. During the period of follow-up one patient who initially had stage IIIA disease developed recurrent tumor. Fifty percent of patients who underwent conservative fertility-sparing surgical treatment (6/12) subsequently conceived.

CONCLUSIONS

This study confirms the excellent prognosis for patients with low malignant potential ovarian tumors. Conservative fertility-saving surgical treatment can be offered to young patients (< 40 years) with early stage (stage I-II) disease who wish to retain their fertility potential. Up to 50% of women in this study who underwent conservative surgery subsequently conceived. The long-term outcome of LMP ovarian tumors is extremely favorable, even when long-term follow-up is extended to ten years.
