Review of second-line chemotherapy for advanced gastric adenocarcinoma.

Palliative chemotherapy has been shown to improve survival compared with best supportive care alone in patients with unresectable or recurrent gastric cancer. However, patients receiving chemotherapy eventually develop progressive disease. At this stage, no standard second-line chemotherapy can be offered. No randomised-controlled trial data suggest a benefit of second-line chemotherapy compared with supportive care alone. We review the published data concerning the use of second-line chemotherapy in gastric adenocarcinoma. Response rates to second-line therapy in phase II trials are similar to those seen for other cancers that are more commonly retreated. In addition, data suggest that patients who respond to second-line therapy consistently survive longer compared with non-responders, and, perhaps more importantly, symptomatic benefit may be obtained from second-line therapy.
