Abstract

Malignant pleural mesothelioma (MPM) is a rare malignancy characterized by a long latency period of 20–50 years after exposure to the main aetiology agent that is asbestos. MPM treatments include surgery, chemotherapy, and radiation therapy, with the combination pemetrexed and cisplatin being the standard chemotherapy approach. Despite this multimodality therapy one of the major issues after surgery is the high rate of local recurrence of the tumor. One possible approach would be the intrapleural application of implants loaded with anticancer drug to be applied during surgery to prevent local tumor recurrence. The implant proposed in the present work is a polymeric film of hyaluronic acid loaded with pemetrexed. The film developed is a hydrophilic, thin and flexible film sufficiently resistant to be applied intrapleurally adhering to the mesothelial surface. The release of pemetrexed from the film was found to be complete within 2 h in phosphate buffered saline. In an orthotopic model of mesothelioma recurrence in rats, pemetrexed loaded films showed the same antitumor efficacy of pemetrexed disodium solutions administered intravenously or intrapleurally, while when administered in combination with cisplatin-loaded hyaluronate film, the implants almost completely prevented tumor recurrence. The local administration of drug-loaded polymer implants appears an ideal chemotherapy strategy especially for patients in which surgery is already selected as a viable therapeutic option.
