Abstract:
The objective of this study was to analyze the outcome of patients with malignant pleural mesothelioma who were treated from 1993 to 2009. We analyzed a total of 28 patients with malignant pleural mesothelioma. All the patients were males, except for two females and the mean age was 64.5 years old. Twelve and 16 of the patients underwent an extrapleural pneumonectomy and a pleural biopsy, respectively. The histological types included 14 epithelial type, 8 biphasic type, and 6 sarcomatoid type. Three patients were classified as stage I, 8 as stage II, 9 as stage III, and 8 as stage IV. Fourteen and eight of the patients underwent systemic chemotherapy and radiotherapy, respectively. The 2-year survival rate of all the patients was 25.7%, and the 2-year survival of the patients with at least one more modalities of the treatments with chemotherapy, radiotherapy and extrapleural pneumonectomy were much higher than those without. We should therefore consider selecting a multimodality treatment for such patients because the administration of either systemic chemotherapy or radiotherapy was found to be associated with a favorable prognosis.
Insights
Multimodality treatment significantly improves survival for malignant pleural mesothelioma patients. Combining chemotherapy, radiotherapy, and surgery offers a better prognosis than single-modality approaches.
Area of Science:
- Oncology
- Thoracic Surgery
- Medical Research
Context:
- Malignant pleural mesothelioma is a rare and aggressive cancer.
- Treatment outcomes for this condition have historically been poor.
- Understanding the impact of different treatment modalities is crucial.
Purpose:
- To analyze the treatment outcomes of patients with malignant pleural mesothelioma.
- To evaluate the effectiveness of various therapeutic interventions, including surgery, chemotherapy, and radiotherapy.
- To identify factors associated with improved survival rates.
Summary:
- A retrospective analysis of 28 malignant pleural mesothelioma patients treated between 1993 and 2009.
- Patients received treatments including extrapleural pneumonectomy, pleural biopsy, systemic chemotherapy, and radiotherapy.
- The 2-year survival rate was 25.7%; multimodality treatment showed significantly higher survival than single-modality approaches.
Impact:
- Multimodality treatment, incorporating chemotherapy and/or radiotherapy with surgery, is associated with a favorable prognosis.
- Findings suggest that a combined therapeutic strategy should be considered for malignant pleural mesothelioma.
- This research contributes to optimizing treatment protocols for this challenging cancer.

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.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
