Customizing chemotherapy in lung cancer: New phase II data reported

Measuring the expression levels of an enzyme involved in DNA synthesis can help predict the response of lung cancers to certain treatments, a Korean study has shown. In a randomized phase II study, researchers showed that patients whose lung cancers expressed low levels of an enzyme called thymidylate synthase experienced a greater benefit from treatment with the combination of pemetrexed and cisplatin than those whose tumors expressed high levels.
