Abstract:
Malignant mesothelioma is an aggressive tumour of the serosal surfaces with poor prognosis and increasing incidence due to widespread previous asbestos exposure. Relative chemotherapeutic and radiotherapeutic resistance makes malignant pleural mesothelioma (MPM) difficult to manage, even though encouraging results were achieved with multimodality treatment. Better knowledge of angiogenesis and molecular pathways involved in MPM seems to be the right way to define new targets for systemic treatment. Neoangiogenesis may be considered as a critical step in the development of mesothelioma. Vascular endothelial growth factor (VEGF) and platelet derived growth factor (PDGF) are autocrine growth factors in MPM and epidermal growth factor receptor (EGFR) appears highly expressed in this tumour. Tyrosine kinase inhibitors (TKIs) targeting growth factors like vandetanib, dasatinib, and angiogenesis inhibitors like bevacizumab, are among the most promising agents under evaluation in clinical trials. Mesothelioma is a malignancy which owes its chemoresistance to an apoptotic defect. Thus the introduction of new biologic drugs like vorinostat, bortezomib, everolimus and temsirolimus, in the treatment of MPM finds a strong rationale. This review focuses on the current target therapies and evaluates future biologic approaches for the systemic management of MPM.
Insights
Malignant pleural mesothelioma (MPM) is a challenging cancer due to resistance to traditional therapies. New targeted drugs focusing on angiogenesis and molecular pathways offer promising systemic treatment options for this aggressive tumor.
Area of Science:
- Oncology
- Cancer Biology
- Molecular Medicine
Background:
- Malignant mesothelioma, particularly malignant pleural mesothelioma (MPM), is an aggressive cancer with increasing incidence linked to asbestos exposure.
- MPM exhibits resistance to chemotherapy and radiotherapy, necessitating novel treatment strategies.
- Understanding the molecular pathways, including angiogenesis, is crucial for developing effective systemic therapies.
Purpose of the Study:
- To review current targeted therapies for malignant pleural mesothelioma.
- To evaluate future biologic approaches for the systemic management of MPM.
- To highlight the role of angiogenesis and molecular targets in MPM treatment.
Main Methods:
- Review of current literature on targeted therapies and biologic agents for MPM.
- Analysis of molecular pathways involved in MPM, including growth factors and apoptotic defects.
- Evaluation of clinical trial data for promising agents targeting angiogenesis and molecular pathways.
Main Results:
- Vascular endothelial growth factor (VEGF), platelet derived growth factor (PDGF), and epidermal growth factor receptor (EGFR) are key molecular targets in MPM.
- Tyrosine kinase inhibitors (TKIs) and angiogenesis inhibitors show promise in clinical trials.
- Biologic drugs targeting apoptotic defects are being explored for MPM treatment.
Conclusions:
- Targeted therapies and biologic agents represent a promising future for MPM systemic management.
- Further research into molecular pathways and angiogenesis is essential for defining new therapeutic targets.
- Multimodality treatment combined with novel systemic approaches may improve outcomes for MPM patients.
