Greetings, dear reader! In this article, we will discuss the differences between pleural mesothelioma and peritoneal mesothelioma. Both are rare and fatal types of cancer caused by asbestos exposure. However, they affect different parts of the body and have distinct symptoms, treatments, and prognosis. If you or someone you know has been diagnosed with mesothelioma, it is crucial to understand the type and stage of the disease to make informed decisions about treatment, support, and legal options. We hope that this guide will help you to navigate the complex and challenging journey of mesothelioma with clarity and hope.
What is Mesothelioma?
Mesothelioma is a type of cancer that affects the mesothelium, a thin layer of tissue that covers and protects many organs and body cavities. The mesothelium produces a lubricant fluid that enables smooth movement and prevents friction between the organs and tissues. However, when asbestos fibers are inhaled or ingested, they can penetrate the mesothelium and cause inflammation, scarring, and genetic damage that may lead to cancerous cell growth. Mesothelioma can develop in various parts of the mesothelium, including the pleura (lining of the lungs), peritoneum (lining of the abdomen), pericardium (lining of the heart), and testicles (lining of the tunica vaginalis).
Mesothelioma is a rare and aggressive cancer, with a latency period of 20-50 years between exposure and symptoms. Most people who develop mesothelioma have worked or lived in environments with high levels of asbestos, such as construction sites, shipyards, factories, mines, and military bases. However, mesothelioma can also affect family members and bystanders who were exposed to asbestos fibers brought home on the clothes, skin, or hair of the workers. There is no cure for mesothelioma, but various treatments can help to relieve symptoms, improve quality of life, and extend survival.
What is Pleural Mesothelioma?
Pleural mesothelioma is the most common type of mesothelioma, accounting for about 75% of cases. Pleural mesothelioma affects the lining of the lungs, called the pleura. The pleura has two layers, the inner layer covering the lungs and the outer layer lining the chest wall. Between the two layers, there is a thin space called the pleural cavity, which contains a small amount of lubricant fluid that allows the lungs to expand and contract with breathing. When pleural mesothelioma develops, it usually starts as tiny nodules on the pleural surface and gradually spreads to form a thick, irregular, and invasive mass that compresses the lungs and other nearby organs.
Symptoms of Pleural Mesothelioma
Symptoms of pleural mesothelioma may not appear until several decades after asbestos exposure. The initial symptoms may be mild and unspecific, such as fatigue, cough, chest pain, and shortness of breath. However, as the cancer progresses, the symptoms may become more severe and debilitating, such as:
| Symptom | Description |
|---|---|
| Dyspnea | Shortness of breath, even at rest or with minimal exertion |
| Chest pain | Sharp, dull, or pressure-like pain in the chest, back, or shoulder |
| Cough | Dry or productive cough, hoarseness, or wheezing |
| Pleural effusion | Buildup of fluid in the pleural cavity, causing breathlessness or chest discomfort |
| Fatigue | Feeling tired, weak, or lethargic, even with adequate rest |
| Fever | Low-grade fever, night sweats, or chills |
| Weight loss | Unintentional loss of appetite, muscle mass, or body weight |
It is essential to note that these symptoms may resemble other respiratory or cardiac conditions and may not be specific to mesothelioma. Therefore, it is crucial to seek medical attention if you have been exposed to asbestos and experience any unusual or persistent symptoms.
What is Peritoneal Mesothelioma?
Peritoneal mesothelioma is a rare and aggressive cancer that affects the peritoneum, a thin layer of tissue that lines the abdominal cavity and covers many vital organs, such as the stomach, liver, and intestines. The peritoneum has two layers, the visceral layer that covers the organs and the parietal layer that lines the abdominal wall. The peritoneum produces lubricant fluid that enables the movement and digestion of the organs. When peritoneal mesothelioma develops, it usually starts as small nodules on the peritoneal surface and gradually spreads to form a thick, invasive, and diffuse coating that interferes with the organ function.
Symptoms of Peritoneal Mesothelioma
Symptoms of peritoneal mesothelioma may vary depending on the stage and extent of the cancer. In the early stages, peritoneal mesothelioma may not cause any noticeable symptoms, or the symptoms may be mild and unspecific, such as:
| Symptom | Description |
|---|---|
| Abdominal pain | Dull, cramping, or sharp pain in the abdomen, pelvis, or back |
| Abdominal swelling | Bloating, distention, or fluid retention in the abdomen |
| Nausea | Feeling of queasiness, vomiting, or indigestion |
| Bowel changes | Diarrhea, constipation, or changes in bowel habits |
| Anorexia | Lack of appetite, weight loss, or malnutrition |
| Fever | Low-grade fever, night sweats, or chills |
| Fatigue | Feeling tired, weak, or lethargic, even with adequate rest |
As peritoneal mesothelioma progresses, the symptoms may become more severe and debilitating, such as:
| Symptom | Description |
|---|---|
| Ascites | Excessive fluid buildup in the abdomen, causing discomfort, pressure, or hernia |
| Bowel obstruction | Blockage of the intestine, causing cramps, nausea, vomiting, or constipation |
| Malignant mesothelioma cell invasion of adjacent organs | Spread of cancerous cells to other organs in the abdominal cavity, such as the liver, spleen, or pancreas |
| Thrombosis | Formation of blood clots in the blood vessels, causing pain, swelling, or embolism |
What are the differences between Pleural Mesothelioma and Peritoneal Mesothelioma?
Although both pleural mesothelioma and peritoneal mesothelioma share some similarities in terms of causes, treatments, and prognosis, there are some essential differences that distinguish them:
| Parameter | Pleural Mesothelioma | Peritoneal Mesothelioma |
|---|---|---|
| Location | The pleura, lining of the lungs | The peritoneum, lining of the abdomen |
| Symptoms | Chest pain, shortness of breath, cough, pleural effusion, fatigue, fever, weight loss | Abdominal pain, swelling, nausea, bowel changes, anorexia, fever, fatigue, ascites, bowel obstruction, organ invasion, thrombosis |
| Diagnosis | Chest X-ray, CT scan, MRI, PET scan, biopsy, fluid analysis | Abdominal CT scan, PET scan, biopsy, fluid analysis |
| Treatment | Surgery, chemotherapy, radiation therapy, immunotherapy, palliative care | Debulking surgery, HIPEC, chemotherapy, radiation therapy, immunotherapy, palliative care |
| Prognosis | Median survival of 12-21 months, depending on the stage and response to treatment | Median survival of 6-12 months, depending on the stage and response to treatment |
As you can see, while pleural mesothelioma affects the lungs and causes respiratory symptoms, peritoneal mesothelioma affects the abdomen and causes digestive symptoms. Therefore, the diagnosis, treatment, and prognosis of the two types may differ to some extent. However, it is crucial to note that each case of mesothelioma is unique and may require a personalized and multidisciplinary approach.
