Ovarian cancer continues to be a major cause of morbidity and mortality in women. Antiangiogenic treatments have emerged as a promising strategy to treat ovarian cancer. This article reviews the rationale supporting the use of antiangiogenic treatments in ovarian cancer, the clinical development of this group of drugs and the toxicities specific to this modality of treatment.

Disease progression on 2 consecutive lines of therapy should be used as a guide to discontinue cytotoxic treatment. A subset of patients with poor prognosis at the onset of platinum resistance, who may have little gain from anticancer treatment, can be identified.

The MTD of GSAO was 22.0 mg/m(2)/day. There was no biomarker evidence from DCE-MRI or circulating markers of angiogenesis of an anti-vascular effect of GSAO.
