Hello and welcome to this journal article about the different types of mesothelioma. Mesothelioma is a rare form of cancer that primarily affects the lining of the lungs, heart, or abdomen. It is caused by exposure to asbestos, a naturally occurring mineral that was widely used in various industries until the late 20th century.
There are several types of mesothelioma, each with its own unique characteristics and treatment options. In this article, we will explore the different types of mesothelioma and provide you with the information you need to know about this rare form of cancer.
1. Pleural Mesothelioma
Pleural mesothelioma is the most common type of mesothelioma, accounting for approximately 75% of all cases. It affects the lining of the lungs and can cause symptoms such as chest pain, shortness of breath, and persistent coughing.
There are three main subtypes of pleural mesothelioma:
A. Epithelioid Pleural Mesothelioma
This subtype accounts for approximately 60% of all pleural mesothelioma cases. It is the most treatable subtype and has a better prognosis than the other subtypes.
B. Sarcomatoid Pleural Mesothelioma
This subtype accounts for approximately 10% of all pleural mesothelioma cases. It is the least treatable subtype and has the worst prognosis, with most patients surviving less than a year after diagnosis.
C. Biphasic Pleural Mesothelioma
This subtype accounts for approximately 30% of all pleural mesothelioma cases. It is a combination of both epithelioid and sarcomatoid subtypes and has a variable prognosis depending on the ratio of each subtype.
2. Peritoneal Mesothelioma
Peritoneal mesothelioma affects the lining of the abdomen and accounts for approximately 20% of all mesothelioma cases. It can cause symptoms such as abdominal pain, swelling, and digestive issues.
There are two main subtypes of peritoneal mesothelioma:
A. Diffuse Malignant Peritoneal Mesothelioma
This subtype is the most common type of peritoneal mesothelioma and accounts for approximately 85% of cases. It is characterized by widespread tumor growth throughout the abdominal cavity and is typically treated with a combination of surgery and chemotherapy.
B. Localized Malignant Peritoneal Mesothelioma
This subtype is the rarest form of mesothelioma and accounts for approximately 15% of cases. It is characterized by a single tumor mass in the abdominal cavity and is typically treated with surgery.
3. Pericardial Mesothelioma
Pericardial mesothelioma affects the lining of the heart and is the rarest form of mesothelioma, accounting for less than 1% of all cases. It can cause symptoms such as chest pain, heart palpitations, and shortness of breath.
There is no established staging system for pericardial mesothelioma, and treatment options are limited. Most patients receive palliative care to manage their symptoms and improve their quality of life.
