Opinion Statement:
Malignant pleural mesothelioma (MPM) is an aggressive asbestos-associated thoracic malignancy that is usually incurable. As demonstrated in the landmark MARS2 trial, surgical resection does not improve survival outcomes and its role in managing MPM is limited. Whilst platinum-pemetrexed chemotherapy in combination with bevacizumab was the standard first-line approach for unresectable disease, landmark phase 3 trials have now established the role of immune checkpoint inhibitors (CPIs) in the upfront management of unresectable disease: either nivolumab-ipilimumab or carboplatin-pemetrexed-pembrolizumab. Patient selection for optimal strategy remains an ongoing question. For relapsed disease novel genomic-based therapies targeting a range of aberrations including losses of the tumour suppressor genes BAP1, CDKN2A and NF2, are being evaluated. Nonetheless, the future of MPM therapeutics holds promise. Here we overview current treatment strategies in the management of MPM.
Insights
Malignant pleural mesothelioma (MPM) treatment is evolving. Immune checkpoint inhibitors are now standard for unresectable MPM, with ongoing research into genomic therapies for relapsed disease.
Area of Science:
- Oncology
- Thoracic Surgery
- Medical Oncology
Background:
- Malignant pleural mesothelioma (MPM) is an aggressive, asbestos-associated thoracic cancer with limited curative options.
- Surgical resection has shown limited survival benefit in MPM management.
- Previous first-line treatment for unresectable MPM involved platinum-pemetrexed chemotherapy with bevacizumab.
Purpose of the Study:
- To overview current treatment strategies for malignant pleural mesothelioma.
- To highlight the evolving landscape of MPM therapeutics.
- To discuss patient selection for optimal treatment strategies.
Main Methods:
- Review of landmark phase 3 clinical trials.
- Analysis of current first-line and relapsed disease treatment approaches.
- Discussion of emerging genomic-based therapies.
Main Results:
- Immune checkpoint inhibitors (CPIs) are now established in the upfront management of unresectable MPM.
- CPI regimens include nivolumab-ipilimumab or carboplatin-pemetrexed-pembrolizumab.
- Novel genomic-based therapies targeting tumor suppressor gene aberrations are under evaluation for relapsed MPM.
Conclusions:
- The treatment paradigm for MPM has shifted towards immunotherapy.
- Optimizing patient selection for specific therapeutic strategies is crucial.
- Future MPM therapeutics show promise with ongoing research and development.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
