Introduction
What is Malignant Pleural Mesothelioma?
Malignant pleural mesothelioma is a type of cancer that affects the mesothelium, a protective lining that covers the lungs and chest wall. It is caused by exposure to asbestos, a naturally occurring mineral used in industries such as construction, shipbuilding, and automotive. When asbestos fibers are inhaled, they get lodged in the lungs and trigger an inflammatory response that leads to mesothelioma.
What are the Symptoms of Malignant Pleural Mesothelioma?
The symptoms of malignant pleural mesothelioma may not appear until several years after exposure to asbestos. The initial symptoms mimic those of other respiratory diseases and include coughing, shortness of breath, chest pain, and fatigue. As the disease progresses, the symptoms become more severe and include difficulty breathing, hoarseness, weight loss, and fever.
How is Malignant Pleural Mesothelioma Diagnosed?
Diagnosing malignant pleural mesothelioma is a challenging process as the symptoms are non-specific and overlap with other respiratory diseases. A combination of imaging tests such as X-rays, CT scans, and PET scans are used to detect abnormalities in the lungs. Biopsies, where a small tissue sample is extracted from the lungs, are performed to confirm the diagnosis.
What are the Treatment Options for Malignant Pleural Mesothelioma?
The treatment for malignant pleural mesothelioma depends on the stage and severity of the disease. Surgery, chemotherapy, and radiation therapy are the primary treatment options. Surgery involves removing the cancerous tissues, whereas chemotherapy and radiation therapy aim to destroy the cancer cells. Immunotherapy, a new treatment approach, involves boosting the body’s immune system to attack the cancer cells.
What is the Prognosis for Malignant Pleural Mesothelioma?
The prognosis for malignant pleural mesothelioma is poor, with a 5-year survival rate of less than 10%. This is because the disease is usually diagnosed at a late stage when the cancer has spread to other parts of the body. However, early detection and prompt treatment can improve the prognosis and increase the chances of survival.
What is the Objective of this Study?
The objective of this study is to analyze the postmortem findings of patients who had succumbed to malignant pleural mesothelioma. The study was conducted in two centers and includes 318 patients. The study aims to shed light on the causes, patterns, and distribution of malignant pleural mesothelioma and provide insights into the disease’s diagnosis, treatment, and prevention.
What are the Methods Used in this Study?
The study was conducted in two centers, and the patients’ medical records were analyzed to obtain the necessary data. The diagnoses were confirmed by postmortem examination of the lungs and pleura. The data obtained were analyzed to determine the causes, patterns, and distribution of malignant pleural mesothelioma.
What are the Key Findings of this Study?
The study found that malignant pleural mesothelioma was caused by exposure to asbestos in all the cases analyzed. The study also found that the disease is more prevalent in men than in women, with a male-to-female ratio of 4:1. The study further showed that the most common symptom of malignant pleural mesothelioma is shortness of breath, followed by chest pain and coughing. The study also revealed that the median survival time after diagnosis was less than a year.

Postmortem Findings of Malignant Pleural Mesothelioma: A Detailed Explanation
Pattern and Distribution of Mesothelioma
The study found that the malignant mesothelioma was mainly found in the pleural membranes covering the lungs. Several cases also showed the involvement of other organs such as the liver, spleen, and heart. The distribution of the cancerous tissues was localized in some cases, whereas it had spread to different parts of the body in others.
Exposure to Asbestos as a Major Cause of Mesothelioma
All the cases analyzed in this study had a history of exposure to asbestos. The exposure to asbestos was mainly occupational, with the majority of the patients having worked in industries such as construction, shipbuilding, and automotive. However, some patients had been exposed to asbestos through environmental sources such as living near asbestos mines or factories.
Gender and Age Distribution
The study found that malignant pleural mesothelioma was more prevalent in men, with a male-to-female ratio of 4:1. The age of the patients ranged from 23 to 87 years, with the majority being in the age group of 60-79 years.
Symptoms of Malignant Pleural Mesothelioma
The study found that the most common symptom of malignant pleural mesothelioma was shortness of breath, followed by chest pain and coughing. Other symptoms included fatigue, weight loss, and fever. The symptoms were non-specific and overlapped with other respiratory diseases, making the diagnosis challenging.
Diagnosis and Staging of Mesothelioma
The study found that the diagnosis of malignant pleural mesothelioma was confirmed by a combination of imaging tests such as X-rays, CT scans, and PET scans. Biopsies were performed to extract small tissue samples from the lungs and confirm the diagnosis. The disease was staged based on the extent of the cancerous tissues and the involvement of lymph nodes.
Treatment Options for Mesothelioma
The study found that the treatment options for malignant pleural mesothelioma included surgery, chemotherapy, radiation therapy, and immunotherapy. Surgery involved removing the cancerous tissues, whereas chemotherapy and radiation therapy aimed to destroy the cancer cells. Immunotherapy involved boosting the body’s immune system to attack the cancer cells.
Prognosis and Survival Rate
The study found that the prognosis for malignant pleural mesothelioma was poor, with a 5-year survival rate of less than 10%. The disease was usually diagnosed at a late stage when the cancer had spread to other parts of the body, making it difficult to treat. However, early detection and prompt treatment could improve the prognosis and increase the chances of survival.
Prevention and Awareness
The study underscores the need for creating awareness about the hazards of asbestos exposure and the importance of preventive measures. Workers in industries that use asbestos must be educated about the risks of exposure and provided with appropriate protective gear. The study also emphasizes the importance of early detection through regular health check-ups and screening.
