Hormonal therapy for adjuvant treatment of ovarian cancer may provide a low toxicity option in some patients with refractory disease. A 53 year-old patient with stage IIIC papillary serous ovarian cancer previously treated with multiple chemotherapy regimens with platinum-resistant disease was treated with antiestrogen therapy for 28 months before requiring reinstitution of cytotoxic chemotherapy. Hormonal therapy may be effective in a subset of epithelial ovarian cancer patients with endocrine sensitivity and should be considered in the treatment of platinum-resistant patients.
