Malignant peritoneal mesothelioma (MPM) who responded to rechallenge with cisplatin and pemetrexed with current literature review.

Peritoneal mesothelioma is an aggressive malignancy which is indeed very rare. Due to rarity, experience among many physicians surrounding the treatment of peritoneal mesothelioma is limited. Recently, we have received a patient who was initially treated palliatively with a combination of pemetrexd and cisplatin showing good response. On progression of his disease, he was again treated with the same drugs. This is not the strategy commonly used. We consider rechallenging cisplatin and pemetrexd to such patients who respond for the first time.
