Systemic therapy in malignant mesothelioma: treat it or leave it

Gemcitabine was examined as switch maintenance therapy after standard first line chemotherapy in the NVALT19 trial, which provided the first conformation of gemcitabine activity in malignant mesothelioma (MM). We describe additional analyses to confirm the prognostic value of CYFRA 21-1 and examine the prognostic value of CYFRA 21-1 in MM patients treated with gemcitabine. We also searched how gemcitabine could improve antitumor immune responses by positively modulating the immune system.In this thesis we describe a cohort of 107 malignant mesothelioma patients treated with nivolumab in the Netherlands. The real- world data of single agent PD-1 blocking were disappointing compared to previous reported single arm phase II trials. To examine clinical and peripheral blood biomarkers univariable and multivariable analyses were performed.As malignant peritoneal mesothelioma is even rarer then pleural mesothelioma, we hypothesized that centralization of care for peritoneal mesothelioma could benefit patients as they would likely receive treatment more often.Prognosis has a significant influence on the treatment preferences of patients, but prognosis of individual MM patients is variable and is hard to predict. We presented the MESOPRO score for patient with MM which are about the start with any systemic treatment.
