RESUMEN
In analogy to Kühnle et al. (1984) the role of etoposide in patients with cisplatin-refractory ovarian cancer was evaluated. 45 patients were treated with 150-200 mg of etoposide per sa. m. on days 1-3. Acute toxicity was tolerable except alopecia grade III. Remarkable, however, was the induction of two fatal cases of leukaemia following etoposide treatment. The first patient, who was 27 years old, with FIGO stage IIb serous cystadenocarcinoma, which was treated with cisplatin/epirubicin and after a latent period of 45 months, a local recurrence was treated with 8 cycles of etoposide. Twenty-three months after discontinuation of etoposide therapy, the patient showed acute myelogenous leukaemia (AML) of M5b-subtype according to the FAB classification. Two days after diagnosis, the patient died of the disease. The second patient, a 55-year old woman with FIGO stage IIa serous cystadenocarcinoma, was treated with cisplatin/cytoxan; 8 cycles of etoposide were given as a second line therapy. This patient, 21 months after discontinuation of etoposide therapy showed a pre-pre-B-acute lymphocytic leukaemia with coexpression of the myeloid antigens. Two months after diagnosis, the patient died of the disease. In 4 out of 38 patients, a complete and in 7 patients a partial remission was induced by etoposide treatment and survival of these responding patients was prolonged in comparison with the nonresponder. The survival was also dependent on CA-125 serum level and the cumulative dose of etoposide administered. Etoposide treatment is an acceptable option as salvage therapy in refractory ovarian cancer.(ABSTRACT TRUNCATED AT 250 WORDS)
