[Clinical experience with chemotherapy of the malignant tumor of germinal cells (dysgerminoma) of the ovary].
OBJECTIVE
To evaluate two alternative plans of chemotherapy with EP (etoposide, platinum) and BEP (bleomycin, etoposide, platinum) after oncological surgery.


METHODS
A clinical, longitudinal and descriptive study was done, where the cases with pure dysgerminoma diagnosed in the gynecology-oncology service during the years from 1992 to 2003 were included. Information was recollected in a precoding survey that included sociodemographic characteristics, tumor size, free survival of disease, general survival, recurrence index and the index of fertility.


RESULTS
The age of the group studied was of 22.1 +/- 6.5 years, with stratification to 9 patients in phase I (50%), phase III in 7 patients (38.9%) and phase IV in 2 patients (11.1%). Histological study confirmed the pure dysgerminoma, with a mean duration of the symptoms of 5.2 months, the free survival of disease was of 39.6 months and general survival was of 49.5 months. It was administered early chemotherapy in 11 patients, from which 7 received EP and the other 4 received BEP. Eight patients were found in advanced phases and with metastasis. There were 4 (22.2%) recurrences, of which 3 corresponded to phase III and a case to phase IV with tumors all of them over 15 cm. There were 3 patients rescued with chemotherapy of second line and a patient with radiotherapy to central nervous system. The statistical analysis showed that size of tumor among the recurrent group (24.2 cm) and the group without recurrence (14.5 cm) had significant differences (p = 0.018), the size of the tumor and the free survival of disease did not have significant correlation (p = 0.99), but upon comparing the general survival with the phase of the disease, a significant correlation was found (p = 0.03), where the survival to 5 years was observed in 6 cases (33.3%), of which a case was treated with surgery and without chemotherapy, 4 cases with EP and a case with BEP. Out of the 11 cases treated with conservative surgery, two patients got pregnancy in three occasions.
