Malignant carcinoid syndrome. Failure of anti-oestrogenic therapy

A pre-menopausal patient with a six-year history of symptoms of the metastatic carcinoid syndrome leading to progressively worsening carcinoid heart disease is described. The failure of anti-oestrogenic therapy (sequential bilateral oophorectomy and Tamoxifen therapy) to halt progression of disease was documented. Death resulted from right ventricular failure associated with pulmonary and tricuspid valvular disease.
