Home> Malignant Mesothelioma> Diagnosis and Treatment

Both diagnosing and treating malignant mesothelioma demand a meticulous and comprehensive approach, including imaging tests and biopsies. Treatment strategies, such as surgery, chemotherapy, and targeted therapies, are customized to individual case parameters, striving for optimal outcomes.

Malignant Mesothelioma Diagnosis Tests

Doctors recommend various tests for malignant mesothelioma diagnosis. Commonly recommended tests for malignant mesothelioma include blood tests, imaging tests, and biopsies. Along with the diagnosis, some of these tests also help with disease staging, treatment planning, and treatment monitoring. The following are the different tests recommended for malignant mesothelioma diagnosis:

Medical History and Physical Examination

During a malignant mesothelioma diagnosis, a thorough medical history review and physical examination are recommended as initial steps. Gathering information about asbestos exposure, occupational history, and any presenting symptoms is crucial. The physical examination aims to identify potential signs, such as chest or abdominal abnormalities, that may warrant further investigation.

Imaging Tests

Imaging tests help obtain detailed images of the internal structures through various techniques. Imaging tests play a pivotal role in malignant pleural mesothelioma diagnosis and sarcomatoid mesothelioma diagnosis. The following are the different imaging tests recommended for malignant mesothelioma diagnosis:

Chest X-ray

A chest X-ray is often the first imaging test conducted to detect abnormalities in the lungs or pleura. While it can reveal the presence of pleural effusion or thickening, additional imaging tests are usually required for a comprehensive diagnosis.

Computed Tomography (CT) Scan

CT scans provide detailed cross-sectional images of the chest or abdomen, offering a more comprehensive view than X-rays. They are instrumental in identifying the extent of tumor growth, assessing lymph nodes, and guiding further diagnostic procedures.

Echocardiogram

For suspected pericardial mesothelioma, an echocardiogram is employed to evaluate the heart and pericardium. This imaging test helps detect abnormalities, such as fluid accumulation around the heart, aiding in the diagnostic process.

Positron Emission Tomography (PET) Scan

A PET scan involves the injection of a radioactive substance to highlight areas with increased metabolic activity. As a test recommended for malignant mesothelioma diagnosis, a PET scan is effective in locating malignant cells and determining the spread of mesothelioma to distant organs or tissues.

Magnetic Resonance Imaging (MRI) Scan

MRI scans utilize magnetic fields and radio waves to generate detailed images. During malignant mesothelioma diagnosis, MRIs help in assessing soft tissues, providing valuable information about the extent of tumor involvement, and aiding in treatment planning.

Blood Tests

In the diagnostic journey for malignant mesothelioma, blood tests play a supportive role. While there is no specific blood test exclusively for mesothelioma, certain markers, such as mesothelin-related proteins, may be elevated in individuals with the disease. Blood tests can aid in identifying potential abnormalities and contribute to a comprehensive diagnostic assessment when considered alongside other diagnostic methods.

Tests of Fluid and Tissue Samples

To confirm a mesothelioma diagnosis, tests involving fluid and tissue samples are imperative. A biopsy, which involves extracting a small tissue sample for examination, is a definitive method. For pleural mesothelioma, thoracentesis collects fluid from the chest cavity, while peritoneal mesothelioma may involve paracentesis for abdominal fluid. These tests provide crucial insights into the cellular composition, confirming the presence of mesothelioma and guiding treatment decisions.

Biopsy

A biopsy is a fundamental diagnostic procedure for confirming malignant mesothelioma. It involves the removal of a small tissue sample from the suspected tumor site for microscopic examination. Biopsies are crucial for determining the mesothelioma subtype and guiding treatment decisions.

Needle Biopsies

Needle biopsies are minimally invasive procedures that use a thin needle to extract tissue samples from the affected area. These biopsies, including fine-needle aspiration and a core needle biopsy, are commonly performed under imaging guidance for precision.

Endoscopic Biopsies

Endoscopic biopsies utilize a flexible tube with a camera (an endoscope) to visualize and obtain tissue samples from the affected areas. This less invasive approach is particularly effective for diagnosing peritoneal or pleural mesothelioma.

Thoracoscopy

Thoracoscopy involves the insertion of a thin tube with a camera through a small incision in the chest to examine and biopsy the pleura. This procedure provides a direct visual assessment of the affected area and aids in obtaining targeted tissue samples.

Laparoscopy

Laparoscopy is a similar procedure to thoracoscopy but involves accessing the abdominal cavity. It is commonly used for peritoneal mesothelioma diagnosis, allowing for direct visualization and biopsy collection.

Mediastinoscopy

Mediastinoscopy is employed to examine and biopsy lymph nodes and tissues in the central chest (mediastinum). This procedure is valuable for determining the extent of mesothelioma involvement and identifying potential spread.

Endobronchial Ultrasound Needle Biopsy

Endobronchial ultrasound needle biopsy is a specialized procedure to sample lymph nodes and lesions in the lungs using an ultrasound-guided needle. It is particularly useful for diagnosing pleural mesothelioma.

Open Surgical Biopsy

In certain cases, an open surgical biopsy may be necessary, involving a larger incision to access and collect tissue samples. This approach is reserved for situations where less-invasive methods may not yield sufficient diagnostic material.

Pulmonary Function Tests

Pulmonary function tests assess the functionality of the lungs and are essential in evaluating the impact of malignant mesothelioma on respiratory health. These tests measure lung capacity, airflow, and gas exchange, providing valuable information to guide treatment decisions and address respiratory symptoms associated with the disease.

What Are the Different Malignant Mesothelioma Treatments?

The landscape of malignant mesothelioma treatment is diverse, encompassing various modalities to address this aggressive cancer. The choice of treatment depends on factors such as cancer stage, location, and overall health. Common approaches include chemotherapy, immunotherapy, radiation therapy, surgery, targeted therapy, and tumor-treating fields.

Chemotherapy for Malignant Mesothelioma

Chemotherapy involves the use of drugs to kill or slow the growth of cancer cells. Malignant mesothelioma chemotherapy is a systemic treatment, meaning it circulates throughout the body. It is often employed in mesothelioma care, either as a primary treatment or in conjunction with other modalities, aiming to control and manage the disease.

Immunotherapy for Malignant Mesothelioma

Immunotherapy for malignant mesothelioma harnesses the body's immune system to fight cancer cells. This innovative approach is increasingly used in malignant mesothelioma treatment, with immune checkpoint inhibitors showing promise in enhancing the body's natural defenses against cancer.

Radiation Therapy

Radiation therapy uses high doses of radiation to target and destroy cancer cells. It is a localized treatment commonly employed to shrink tumors or alleviate symptoms. During malignant mesothelioma treatment, radiation therapy can be applied externally (external beam radiation) or internally (brachytherapy), depending on the case.

Surgery

Surgery is crucial in malignant mesothelioma treatment, aiming to remove tumors and affected tissue. Depending on the type of malignant mesothelioma, different types of surgical procedures are available:

Pleural Mesothelioma

Surgery for malignant pleural mesothelioma involves extrapleural pneumonectomy, which refers to the removal of the affected lung, the lining of the chest wall (pleura) on that side, the diaphragm muscle, and the nearby lymph nodes. Pleurectomy or decortication is recommended as another surgical treatment option for pleural mesothelioma, wherein the pleura and visible tumors are removed while preserving the lung.

Peritoneal Mesothelioma

Cytoreductive Surgery with Heated Intraperitoneal Chemotherapy (HIPEC) is recommended as a malignant peritoneal mesothelioma treatment. During this procedure, the doctor will surgically remove as many tumors as possible (cytoreduction) in the abdominal cavity. This is followed by the delivery of warmed anti-cancer drugs directly into the abdominal cavity.

Pericardial Mesothelioma

A pericardectomy is a surgical procedure that removes the sac that surrounds the heart. This procedure alleviates the pressure on the heart and manages symptoms.

Testicular Mesothelioma

For testicular mesothelioma, the removal of the affected testicle and a small portion of healthy tissue that surrounds it is recommended.

Targeted Therapy

Targeted therapy focuses on specific molecules involved in cancer growth. It is still not a standard malignant mesothelioma treatment; however, research studies are constantly exploring targeted therapies that may offer more personalized and effective options, particularly for individuals with specific genetic mutations.

Tumor Treating Fields

Tumor Treating Fields (TTFields) is an emerging treatment modality that uses electric fields to disrupt cancer cell division. Approved for pleural mesothelioma, TTFields involve the use of a portable device that delivers electric fields to the chest area, inhibiting cell division and potentially slowing tumor growth.
