Intrapleural immunotherapy with Corynebacterium parvum in recurrent malignant pleural effusions
Thorax
|November 1, 1980
Summary
Corynebacterium parvum is a superior and well-tolerated treatment for recurrent malignant pleural effusions compared to mustine. This immunotherapy effectively suppressed fluid reaccumulation with minimal side effects.
Area of Science:
- Oncology
- Immunology
- Pulmonology
Background:
- Recurrent malignant pleural effusions present a significant challenge in patient care.
- Current treatment options often have limited efficacy and considerable side effects.
Purpose of the Study:
- To compare the efficacy and tolerability of intrapleural Corynebacterium parvum versus mustine for managing malignant pleural effusions.
- To evaluate the potential of Corynebacterium parvum as an immunotherapy for pleural fluid management.
Main Methods:
- A randomized trial involving 21 patients with recurrent malignant pleural effusions.
- Patients received either intrapleural Corynebacterium parvum (7 mg) or mustine (20 mg), with potential for a repeat dose.
- Efficacy was assessed by the suppression of pleural fluid reaccumulation.
Main Results:
- Corynebacterium parvum demonstrated superior efficacy in suppressing pleural fluid reaccumulation compared to mustine.
- Corynebacterium parvum was associated with minimal side effects (fever, nausea), while mustine caused significant nausea and vomiting.
- All patients who failed mustine therapy responded well to Corynebacterium parvum.
Conclusions:
- Intrapleural Corynebacterium parvum is an effective and well-tolerated agent for managing recurrent malignant pleural effusions.
- The immunological stimulant effect of Corynebacterium parvum may contribute to its therapeutic action, though this requires further investigation.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
01:13Pleura of the Lungs
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...
01:25Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.

Pleural Effusion Overview
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.

01:27Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
