Formestane (4-hydroxyandrostenedione) is an aromatase inhibitor which significantly reduces plasma levels of estrogen and has shown antitumour activity in postmenopausal women with breast cancer. Objective response rates in heavily pretreated patients with advanced breast cancer generally range between 20 and
