to optimize the use <strong>of</strong> erlotinib by adding other targeted<br />

agents. One phase II study <strong>of</strong> combined EGFR and vascular<br />

endothelial growth factor inhibition with erlotinib and bevacizumab<br />

showed promising results. 10 In 53 patients, six<br />

(12%) patients had confirmed partial responses. Median<br />

time to progression was 4.4 months and OS was 9.9 months.<br />

Other investigators have evaluated targeting different proteins<br />

downstream <strong>of</strong> EGFR for better results. Some evidence<br />

<strong>of</strong> activity has been seen with MEK inhibition and biliary<br />

tract cancers. 11 However, better understanding <strong>of</strong> these<br />

pathways in biliary tract cancer will help us to better use the<br />

new, targeted therapies for patients with biliary tract cancers.<br />

Conclusion<br />

Management <strong>of</strong> biliary tract cancers has previously been<br />

limited to fluoropyrimidines; however, over the last several<br />

years, new two-drug combinations have been developed with<br />

evidence <strong>of</strong> better activity than single-agent regimens. Although<br />

gemcitabine/cisplatin have been established as a<br />

standard option for these cancers, other two-drug regimens<br />

appear to have similar results. Now that the era <strong>of</strong> targeted<br />

agents for biliary tract cancers is starting, it is important<br />

that we improve our understanding <strong>of</strong> the biology <strong>of</strong> the<br />

disease and how best to use these new classes <strong>of</strong> agents to<br />

improve the outcomes for patients with these deadly diseases.<br />
