[Problems in diagnosis and therapy of malignant pleural mesothelioma]
Abstract:
The incidence of malignant pleural mesothelioma increased continuously during recent years. This is related to widespread use and processing of asbestos in the last decades. Characteristical symptoms like dyspnea, cough and thoracic pain are common in almost all pulmonal diseases. Therefore the possible occurrence of a pleural tumor is often neglected. This leads to a delay between onset of symptoms and the establishment of diagnosis. With X-ray and computed tomography 80% of the pleural tumors can be proved. Only in few cases the histopathological analysis of the pleural fluid leads to diagnosis. However, thoracoscopy or thoracotomy remain the most reliable means of obtaining a definitive tissue diagnosis. At the time of operation advanced stages are found in many cases, therefore palliative surgery is indicated. Due to high morbidity and mortality pleuropneumonectomy should be done only in selected patients. Pleurectomy or pleurodesis is often sufficient to release patients' symptoms. Chemotherapy and radiation have not proven effective in controlling malignant mesothelioma. In conclusion pleural mesothelioma remains a tumor with a very poor prognosis. Long term survival is occasional even in case of multimodal treatment.
Insights
Malignant pleural mesothelioma, linked to asbestos, is increasing. Diagnosis is often delayed due to non-specific symptoms, leading to poor prognosis despite treatment.
Area of Science:
- Oncology
- Pulmonology
- Pathology
Context:
- Rising incidence of malignant pleural mesothelioma globally.
- Association with historical asbestos exposure and processing.
- Non-specific symptoms delaying diagnosis.
Purpose:
- To review the diagnostic challenges and treatment outcomes for malignant pleural mesothelioma.
- To highlight the importance of early diagnosis and appropriate management strategies.
- To discuss the prognostic factors and current therapeutic limitations.
Summary:
- Malignant pleural mesothelioma diagnosis is often delayed due to overlapping symptoms with common lung diseases.
- Imaging techniques like CT scans detect most pleural tumors, but definitive diagnosis requires tissue analysis via thoracoscopy or thoracotomy.
- Advanced stages are frequently found at diagnosis, necessitating palliative surgical interventions.
- While pleurectomy/pleurodesis can alleviate symptoms, pleuropneumonectomy is reserved for select cases due to high risks.
- Current chemotherapy and radiation therapies show limited efficacy in controlling malignant mesothelioma.
- The overall prognosis for malignant pleural mesothelioma remains poor, with long-term survival being rare even with multimodal approaches.
Impact:
- Emphasizes the need for increased awareness among clinicians regarding asbestos-related pleural tumors.
- Underscores the diagnostic utility of advanced imaging and invasive procedures.
- Highlights the limited effectiveness of current systemic therapies and the importance of palliative care.
- Informs prognosis and treatment planning for patients diagnosed with this challenging malignancy.
