Condition Overview

Mesothelioma is a rare and aggressive cancer that develops in the thin layer of tissue (mesothelium) lining the lungs (pleura), abdomen (peritoneum), or, rarely, the heart (pericardium). It is strongly associated with prior asbestos exposure, often occurring decades after the original exposure.

Types and Subtypes

Mesothelioma is classified by anatomical site and by histologic subtype, both of which influence treatment and prognosis.

Symptoms and Signs

Symptoms vary depending on the site involved and are often nonspecific in early disease.

Causes and Risk Factors

Asbestos exposure is the dominant and best-established risk factor for mesothelioma.

Diagnosis and Investigations

Diagnosis combines imaging, tissue biopsy, and specialized pathology review, as mesothelioma can be difficult to distinguish from other cancers.

Staging and Risk Groups

Pleural mesothelioma is staged using a TNM-based system (Stages I–IV); peritoneal disease is often described by extent of spread rather than formal TNM staging.

Standard Treatment

Treatment is multimodal where possible, combining surgery, chemotherapy, and sometimes radiation, tailored to stage, subtype, and overall fitness.

Advanced & Emerging Therapies

Immunotherapy has changed the treatment landscape for mesothelioma, and several other approaches are under active investigation.

  • Immunotherapy

    Nivolumab plus Ipilimumab

    A dual checkpoint inhibitor combination approved as a first-line option for unresectable malignant pleural mesothelioma.

    Approved
  • Hyperthermic Intraperitoneal Chemotherapy (HIPEC)

    Cytoreductive Surgery with HIPEC

    Used in selected peritoneal mesothelioma cases at specialized centers.

    Available
  • Cellular Therapy

    Mesothelin-Targeted CAR-T and TIL Approaches

    Investigational cellular therapies targeting mesothelin-expressing tumor cells are being studied in clinical trials.

    Clinical Trial
  • Antibody-Drug Conjugate

    Mesothelin-Targeted ADCs

    Emerging agents in trials aiming to deliver chemotherapy directly to mesothelin-expressing tumors.

    Investigational

Biomarkers & Precision Medicine

Pathologic and molecular markers help confirm diagnosis and may guide treatment selection.

When to Seek a Second Opinion

Because mesothelioma is rare and treatment approaches vary widely by center experience, a second opinion is often valuable.

Clinical Trials & Research

Prognosis & Outcomes

Prognosis varies considerably based on histologic subtype, stage at diagnosis, and treatment eligibility.

Supportive Care

Supportive care plays a major role in managing symptoms and improving quality of life throughout treatment.
