Abstract

Background/Aim: Malignant mesothelioma is a rare malignancy with limited therapeutic options. Exome-based next-generation sequencing (NGS) techniques may direct the future of molecular targeting and improve systemic therapies for patients with mesothelioma. Materials and Methods: Eleven patients with NGS testing were selected, with a total of 236 somatic cancer-related mutations analyzed. Descriptive and Kaplan-Meier statistics were applied. Results: The median age was 65 years (range=27-73 years); 4 (36%) patients were females. Seven (64%) and four patients (36%) had pleural and peritoneal mesothelioma, respectively. Detectable mutations were found in 86% of the pleural and 50% of the peritoneal mesothelioma patients (overall, 73% of patients). The families of BAP1 (36%), CDKNA2A/B (27%) and NF2 (27%) represented the most frequently mutated genes. The median overall survival for all patients was 20.8 months, with 1- and 2-year survival rates of 91% and 40%, respectively. Conclusion: Genomic alterations as potential therapeutic targets were found by NGS. These findings will help in the development of new screening tools and targeting therapies, and in turn impact the standard-of-care and potentially lengthen disease control and survival periods in the future.
