Complete response in a patient with granulosa cell tumor treated with a combination of leuprolide and tamoxifen.

Background: Adult granulosa cell tumors (GCTs) are frequently hormonally active. Thus, hormonal agents have been evaluated for the treatment of advanced-stage or recurrent disease.

Case Report: A 39-year-old patient presented with recurrent GCT. The patient received multiple treatment modalities, including surgery and 2 different chemotherapy regimens (cisplatin- and taxanebased). Abdominal computed tomography following these treatments showed local recurrence with multiple implants. The patient's inhibin B level increased to 187 pg/ml at this time. The patient was treated with leuprolide 11.25 mg every 3 months and tamoxifen 20 mg twice daily. The patient's inhibin B level began to decrease after 1 month and returned to normal after 4 months. The patient has been maintained on this treatment for 2 years and has tolerated the drugs well.

Conclusion: The combination of leuprolide and tamoxifen had limited side effects in the presented patient and might be a viable treatment option for women with advanced-stage or recurrent adult ovarian GCTs.
