Mesothelioma Treatment: Surgery, Chemotherapy, Radiation Therapy and Emerging Treatments

Mesothelioma is a rare and aggressive cancer primarily caused by exposure to asbestos. It typically affects the lining of the lungs (pleural mesothelioma) or the abdomen (peritoneal mesothelioma), although it can also impact the heart (pericardial mesothelioma) or testes. If you or a loved one has been diagnosed with this condition, understanding the available treatment options is crucial. This detailed guide breaks down everything you need to know about mesothelioma treatment, empowering you with knowledge to make informed decisions.

What Is Mesothelioma?


Mesothelioma is a malignant cancer that forms in the thin layer of tissue covering most internal organs. Its primary cause is asbestos exposure, with symptoms often appearing decades after exposure. Due to its late diagnosis, the disease is challenging to treat but not impossible. Advances in medical science are providing new hope for patients.

Mesothelioma Treatment Options (A Comprehensive Guide) 

Mesothelioma demands an informed and comprehensive approach to treatment. The treatment journey varies depending on the cancer's stage, location, and the patient’s overall health. This section delves deep into the four primary treatment modalities: surgery, chemotherapy, radiation therapy, and emerging treatments and clinical trials, providing detailed insights into how each works, its benefits, challenges, and advancements.

1. Surgery: Removing the Tumor

Surgery plays a pivotal role in mesothelioma treatment, especially in early-stage cases where the tumor remains localized. The goal is to remove as much of the cancer as possible, alleviate symptoms, and improve survival rates. Surgery is often part of a multimodal approach, combined with chemotherapy and/or radiation therapy.

Types of Surgeries for Mesothelioma

a. Extrapleural Pneumonectomy (EPP)

What It Involves: This aggressive surgery removes an entire lung, the pleura (lining of the lungs), part of the diaphragm, and the pericardium (lining of the heart).

Who It’s For: Patients with pleural mesothelioma in early stages.

Pros: Removes most of the cancerous tissue, potentially extending survival.

Cons: High-risk procedure with significant recovery time and potential complications, such as respiratory issues.

b. Pleurectomy with Decortication (P/D)

What It Involves: Removes the pleura and any visible tumors while preserving the lung.

Who It’s For: Patients unable to undergo more radical surgeries like EPP.

Pros: Less invasive than EPP, better quality of life post-surgery.

Cons: May not remove all cancer cells, requiring additional treatments.

c. Cytoreductive Surgery with HIPEC

What It Involves: Commonly used for peritoneal mesothelioma, this procedure removes cancerous tissue in the abdomen, followed by heated intraperitoneal chemotherapy (HIPEC).

Who It’s For: Patients with peritoneal mesothelioma confined to the abdominal cavity.

Pros: Combined with HIPEC, it offers promising survival rates.

Cons: Lengthy procedure with potential complications.

Recovery and Risks

Recovery can take weeks to months, depending on the surgery type and patient’s health.

Risks include infection, bleeding, respiratory problems, and recurrence of mesothelioma.

2. Chemotherapy: Systemic Cancer Treatment

Chemotherapy is one of the most widely used treatments for mesothelioma. It uses drugs to kill or slow the growth of cancer cells, either as a standalone treatment or in combination with surgery and radiation therapy.

How Chemotherapy Works

Chemotherapy drugs target rapidly dividing cells, including cancer cells. While effective, they also affect healthy cells, leading to side effects.

Types of Chemotherapy Used in Mesothelioma


a. Standard Intravenous Chemotherapy

Drugs Used:

Pemetrexed (Alimta): Often paired with cisplatin for pleural mesothelioma.

Carboplatin: An alternative for patients who cannot tolerate cisplatin.

How It Works: Administered intravenously to target cancer cells throughout the body.
b. Heated Intraperitoneal Chemotherapy (HIPEC)

What It Involves: Delivers heated chemotherapy drugs directly to the abdominal cavity post-surgery.

Who It’s For: Exclusively for peritoneal mesothelioma.

Benefits: Localized application minimizes systemic side effects and maximizes drug efficacy.

Benefits of Chemotherapy

  • Reduces tumor size, making surgery more effective.
  • Alleviates symptoms like pain and shortness of breath.
  • Prolongs survival in some cases.

Challenges and Side Effects

Chemotherapy has systemic effects, leading to side effects such as:
  • Fatigue and weakness.
  • Nausea, vomiting, and appetite loss.
  • Hair loss.
  • Increased risk of infections due to low white blood cell count.

Advances in Chemotherapy

a. Maintenance Chemotherapy: 

Administered over an extended period to prevent recurrence.

b. Targeted Chemotherapy: 

Drugs are tailored to attack specific cancer cells, reducing damage to healthy tissues.


3. Radiation Therapy: Targeting Cancer with Precision

Radiation therapy is a localized treatment that uses high-energy rays to destroy cancer cells or slow their growth. It is often used in combination with surgery or chemotherapy to improve outcomes.

Types of Radiation Therapy for Mesothelioma


a. External Beam Radiation Therapy (EBRT)

How It Works: A machine delivers radiation beams to the affected area.

Who It’s For: Patients with pleural mesothelioma, especially after surgery.

Pros: Non-invasive and effective in managing symptoms.

Cons: Requires multiple sessions over weeks.

b. Brachytherapy

How It Works: Radioactive material is placed inside or near the tumor.

Who It’s For: Less common for mesothelioma but can be used in specific cases.

Pros: Directly targets the tumor, sparing nearby healthy tissues.

Cons: Requires precise placement by skilled specialists.

Benefits of Radiation Therapy

  • Reduces the size of tumors, making surgery more effective.
  • Controls symptoms like chest pain and breathing difficulties.
  • Prevents recurrence after surgery.

Side Effects of Radiation Therapy

  • Radiation therapy can lead to localized side effects, including:
  • Skin irritation and redness.
  • Fatigue.
  • Difficulty swallowing (for pleural mesothelioma).

Advances in Radiation Therapy

Intensity-Modulated Radiation Therapy (IMRT): 

Delivers precise radiation doses while minimizing damage to surrounding tissues.

Proton Therapy:

Uses protons instead of X-rays, offering better precision and fewer side effects.

4. Emerging Treatments and Clinical Trials: Hope for the Future

Innovations in mesothelioma treatment are providing new hope for patients. Emerging therapies and clinical trials aim to improve survival rates, manage symptoms, and reduce side effects.

a. Immunotherapy

Immunotherapy enhances the body’s natural immune system to fight cancer.

Checkpoint Inhibitors: Drugs like nivolumab (Opdivo) and ipilimumab (Yervoy) block proteins that prevent the immune system from attacking cancer cells.

CAR-T Cell Therapy: Involves engineering a patient’s immune cells to target mesothelioma cells.

b. Targeted Therapy

Targeted therapy focuses on specific molecules or pathways involved in cancer growth.

Mesothelin-Targeted Therapies: Drugs targeting mesothelin, a protein found on mesothelioma cells, show promise.

Angiogenesis Inhibitors: These drugs block the formation of new blood vessels that tumors need to grow.

c. Gene Therapy

Gene therapy introduces or modifies genetic material within cells to combat cancer. Techniques include:
  • Replacing faulty genes.
  • Introducing genes that enhance the immune system’s ability to fight cancer.

Photodynamic Therapy (PDT)

PDT uses light-activated drugs to destroy cancer cells. A photosensitizing agent is injected into the patient, which is then activated by light during surgery.

Tumor Treating Fields (TTF)

TTF uses electric fields to disrupt cancer cell division. This non-invasive therapy is being studied as an adjunct to chemotherapy.

The Role of Clinical Trials

Clinical trials are critical in testing the safety and efficacy of new treatments. They offer patients access to cutting-edge therapies that are not yet widely available.

Phase I Trials: Focus on safety and dosage.m
