We present four cases of patients who had durable responses from pemetrexed-based chemotherapy who were retreated with a similar regimen upon progression of their mesothelioma. This case series explores the possible role of retreatment with pemetrexed-based chemotherapy as a second line therapeutic option in MPM.
