Gemcitabine for palliative treatment in metastatic breast cancer

Gemcitabine is one of the recently developed drugs with a high efficacy in various malignant tumours and a mild toxicity profile. As monochemotherapy in metastatic breast cancer, gemcitabine yielded response rates up to 46% as first- and second-line treatment. Neutropenia is the clinically most relevant unwanted effect. Haematological and nonhaematological toxicities are mild, making dose reductions, delays of treatment or withdrawal from treatment very rare. The first phase I and phase II studies of gemcitabine in combination with anthracyclines have shown a good toxicity profile and promising remission rates. Phase I experiences with long-time infusion schedules reveal good feasibility and high patient acceptance.
