Currently, the four-drug combination of methotrexate, vinblastine,doxorubicin (Adriamycin), and cisplatin (MVAC) or the two-drug combinationof gemcitabine and cisplatin (GC) represents the standard ofcare for patients with locally advanced and metastatic transitional cellcarcinoma of the urothelium. Recently, there has been a plethora ofdata from other chemotherapeutic regimens. Promising new agents,such as the multitargeted antifolate pemetrexed (Alimta), and new drugcombinations have demonstrated increased efficacy and/or decreasedtoxicity compared with current regimens. Currently, data are availablefrom three phase II studies utilizing pemetrexed or the combination ofpemetrexed/gemcitabine (Gemzar) in patients with locally advanced andmetastatic transitional cell carcinoma of the urothelium. Further investigationof combinations of pemetrexed and other active drugs inthe treatment of patients with locally advanced and metastatic diseaseis warranted.
