Abstract:
In Japan, it is predicted that mesothelioma will rapidly increase in the future. Malignant pleural mesothelioma that accounts for approximately 90% of mesothelioma as a whole has a median survival time of approximately nine months which is considered a poor prognosis. As for the treatment of this disease,extrapleural pneumonectomy or pleurectomy/decortication are available for those patients who can be surgically operated on. However, since a complete cure rate is low when only surgical treatment is performed, generally a multimodality treatment is performed wherein chemotherapy and/or radiotherapy are combined. For chemotherapy, a large-scale randomized phase III study demonstrated that a treatment using two agents: pemetrexed, which is a new multitargeted antifolate, and cisplatin is effective. Pemetrexed will be the drug of first choice for mesothelioma in the future. As other treatment methods, chemohyperthermia, treatments using various kinds of cytokines and angiogenesis inhibitors, genetic treatment and photodynamic therapy have been attempted. The current treatment results for this disease are very poor, and there has been a strong demand for establishing an effective treatment method.
Insights
Malignant pleural mesothelioma has a poor prognosis, with a median survival of nine months. Pemetrexed combined with cisplatin shows promise as a future first-choice chemotherapy for this aggressive cancer.
Area of Science:
- Oncology
- Pulmonology
Context:
- Mesothelioma incidence is rising in Japan.
- Malignant pleural mesothelioma (MPM) accounts for 90% of mesothelioma cases.
- MPM has a poor prognosis with a median survival of approximately nine months.
Purpose:
- To review current and emerging treatment strategies for malignant pleural mesothelioma.
- To highlight the efficacy of pemetrexed and cisplatin chemotherapy.
Summary:
- Surgical options like extrapleural pneumonectomy or pleurectomy/decortication are available but often insufficient for a cure.
- Multimodality treatment combining surgery with chemotherapy and/or radiotherapy is standard.
- A phase III study confirmed the effectiveness of pemetrexed and cisplatin chemotherapy, positioning pemetrexed as a future first-line agent.
- Investigational therapies include chemohyperthermia, cytokine treatments, angiogenesis inhibitors, gene therapy, and photodynamic therapy.
Impact:
- Establishes pemetrexed-based chemotherapy as a key treatment for mesothelioma.
- Underscores the urgent need for more effective mesothelioma treatment modalities.
- Provides a comprehensive overview of therapeutic options for a challenging malignancy.

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.
