Abstract:
Malignant pleural mesothelioma (MPM) is a rare and aggressive malignant disease affecting the mesothelium, commonly associated to asbestos exposure. Therapeutic actions are limited due to the late stage at which most patients are diagnosed and the intrinsic chemo-resistance of the tumor. The recommended systemic therapy for MPM is cisplatin/pemetrexed regimen with a mean overall survival of about 12months and a median progression free survival of less than 6months. Considering that the incidence of this tumor is expected to increase in the next decade and that its prognosis is poor, novel therapeutic approaches are urgently needed. For some tumors, such as lung cancer and breast cancer, druggable oncogenic alterations have been identified and targeted therapy is an important option for these patients. For MPM, clinical guidelines do not recommend biological targeted therapy, mainly because of poor target definition or inappropriate trial design. Further studies are required for a full comprehension of the molecular pathogenesis of MPM and for the development of new target agents. This review updates pre-clinical and clinical data on the efficacy of targeted therapy and immune checkpoint inhibition in the treatment of mesothelioma. Finally, future perspectives in this deadly disease are also discussed.
Insights
Malignant pleural mesothelioma (MPM) is a rare cancer with limited treatment options. This review explores targeted therapies and immune checkpoint inhibitors, highlighting the urgent need for novel approaches to improve survival for this aggressive disease.
Area of Science:
- Oncology
- Mesothelioma Research
- Cancer Therapeutics
Background:
- Malignant pleural mesothelioma (MPM) is an aggressive cancer linked to asbestos exposure.
- Current treatments like cisplatin/pemetrexed offer limited survival benefits (12 months OS, <6 months PFS).
- The incidence of MPM is rising, necessitating urgent development of new therapies.
Purpose of the Study:
- To review current pre-clinical and clinical data on targeted therapy for MPM.
- To evaluate the efficacy of immune checkpoint inhibition in mesothelioma treatment.
- To discuss future perspectives for novel therapeutic strategies in MPM.
Main Methods:
- Comprehensive literature review of pre-clinical studies.
- Analysis of clinical trial data for targeted agents and immunotherapies.
- Synthesis of information on molecular pathogenesis and target identification.
Main Results:
- Targeted therapy is not standard for MPM due to challenges in target definition and trial design.
- Emerging data suggests potential for targeted agents and immune checkpoint inhibitors.
- Further research is crucial for understanding MPM's molecular drivers.
Conclusions:
- Novel therapeutic approaches, including targeted therapy and immunotherapy, are critically needed for MPM.
- Improved understanding of MPM's molecular landscape is essential for developing effective treatments.
- Future research should focus on better target identification and optimized clinical trial designs.

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.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
