[Malignant mesothelioma of the pleura]
Abstract:
Forty cases of malignant mesothelioma diagnosed from 1989 to 1994 at the Department of Pulmonology, Semmelweis Medical School were reviewed retrospectively. In 6 patients (15%) had a history of exposure to asbestos. The possibility of the malignant mesothelioma was raised by the clinical signs and the results of chest X-ray, chest computed tomography and sonography of the chest at their patients. Diagnosis was made by hystological examination of thoracoscopic or needle pleural biopsy in 15 and 8 cases, respectively, by cytological examination of fine needle pleural biopsy or pleural fluid in 7 and 6 cases, respectively, and by thoracotomy in 5 patients. Diagnosis was confirmed by multiple procedures in 11 patients. In six patients, diagnosis of malignant mesothelioma was made only by autopsy. The patients were staged according to Butchart et al. Longer survival was noted in the patients with earlier stages. Single or combined therapeutic modalities such as surgery (in 5 patients), chemotherapy (in 10 patients) and radiotherapy (in 3 patients) were used with additional symptomatic treatment in the majority of the cases. Pleurodesis also was done in 7 cases. There was no difference in survival among patients had received different treatment.
Insights
This retrospective study of malignant mesothelioma cases found that earlier disease staging correlated with longer patient survival. Treatment modalities, including surgery, chemotherapy, and radiotherapy, did not significantly impact survival rates in this cohort.
Area of Science:
- Pulmonology
- Oncology
- Pathology
Context:
- Retrospective review of 40 malignant mesothelioma cases diagnosed between 1989 and 1994.
- Investigated clinical presentation, diagnostic methods, staging, and treatment outcomes.
- Highlighted the role of asbestos exposure in a subset of patients (15%).
Purpose:
- To analyze diagnostic approaches and clinical characteristics of malignant mesothelioma.
- To evaluate the impact of staging and treatment on patient survival.
- To provide insights into the management of malignant mesothelioma.
Summary:
- Diagnosis involved a combination of imaging (X-ray, CT, sonography), histological examination (biopsy), cytology, and autopsy.
- Malignant mesothelioma was staged using the Butchart classification.
- Survival was positively associated with earlier disease stages; treatment modalities showed no significant survival difference.
Impact:
- Emphasizes the prognostic significance of early staging in malignant mesothelioma.
- Suggests that current therapeutic strategies may not substantially alter survival outcomes in advanced disease.
- Informs clinical practice regarding diagnostic workup and prognostic assessment for malignant mesothelioma.
