Treatment of Mesothelioma
Treatment of mesothelioma depends on the stage of the cancer, its location, cell type, and the patient’s overall health.
Mesothelioma is a rare and aggressive cancer, usually linked to asbestos exposure. It is often diagnosed late, which makes cure uncommon. Still, medical advances have created more treatment options. Main treatments include surgery, chemotherapy, radiation, targeted therapy, and immunotherapy.
A team of specialists—oncologists, surgeons, radiologists, and palliative care experts—works together to plan care. The goal may be curative for early stages or palliative to reduce symptoms and improve quality of life.
1. Surgery
Surgery aims to remove as much of the tumour as possible. It works best for patients with early-stage disease and good health. The type of surgery depends on where the cancer is located.
Pleurectomy/Decortication (P/D)
This procedure removes the lung lining and visible tumours while keeping the lung intact. It is offered to patients who cannot have more radical surgery. Benefits include lowering tumour mass, reducing fluid in the lungs, and helping breathing. Recurrence is still common.
Extrapleural Pneumonectomy (EPP)
EPP removes the affected lung, pleura, diaphragm, and heart lining. It is only for carefully selected patients with early-stage epithelioid mesothelioma. Though risky, it can extend life in the right candidates.
Cytoreductive Surgery with HIPEC
Used in peritoneal mesothelioma, this surgery removes abdominal tumours, followed by heated chemotherapy in the abdominal cavity. It has improved survival in select patients.
2. Chemotherapy
Chemotherapy destroys or shrinks tumour cells. It is a main treatment for patients who cannot have surgery.
First-line chemotherapy usually combines pemetrexed and cisplatin, though carboplatin may be used for kidney-sensitive patients. This combination can extend survival and relieve symptoms.
Second-line chemotherapy is for cancers that progress after first-line therapy. Options include vinorelbine, gemcitabine, and experimental drugs from clinical trials. These can help control disease and ease symptoms.
3. Radiotherapy
Radiation uses high-energy rays to kill cancer cells. It usually does not cure mesothelioma but can reduce pain and slow local recurrence.
External Beam Radiation Therapy (EBRT) controls chest pain, shrinks tumours, and prevents local regrowth after surgery. Intensity-Modulated Radiation Therapy (IMRT) targets tumours more precisely while protecting healthy tissue.
4. Immunotherapy
Immunotherapy uses the body’s immune system to fight cancer.
Checkpoint inhibitors like nivolumab and ipilimumab show promise, especially in subtypes less responsive to chemotherapy. These drugs are now approved in many countries for unresectable mesothelioma. Experimental approaches, including CAR-T cells, cancer vaccines, and monoclonal antibodies, are being studied in trials.
5. Targeted Therapy
Targeted therapy attacks specific genes or proteins that drive tumour growth. Research is ongoing in mesothelioma, with agents like angiogenesis inhibitors, mesothelin-targeted drugs, and gene therapy. Patients may access these therapies through clinical trials.
6. Multimodal Therapy
Combining treatments can improve outcomes. Multimodal therapy often includes surgery, chemotherapy, and radiation. It is effective in early-stage pleural mesothelioma but carries higher risk and requires careful patient selection.
7. Palliative Care and Symptom Management
When cure is not possible, palliative care focuses on comfort and quality of life. Treatments can relieve fluid buildup, manage pain with medications or radiation, provide nutrition support, and offer counseling. Early palliative care enhances both comfort and emotional well-being.
8. Clinical Trials
Clinical trials give patients access to new therapies and help advance science. Trials may involve immunotherapy combinations, targeted drugs, new chemotherapy protocols, or gene and virus-based therapies. Oncologists help patients find trials that match their diagnosis and location.
9. Complementary and Alternative Therapies
Some patients use acupuncture, meditation, massage, or nutritional supplements. These do not replace standard treatment but may ease stress and improve comfort. Always discuss complementary therapies with the medical team to avoid risks.
10. Decision-Making and Personalised Care
Treatment must be personalised. Patients, families, and the medical team should make shared decisions. Consider the disease stage, cancer subtype, physical health, side effects, and availability of trials. Seeking second opinions or consulting specialist centres is encouraged.
Final Thoughts
The treatment of mesothelioma is complex and always evolving. While most cases are not curable, new therapies, especially immunotherapy and combined strategies, improve survival and life quality. Early diagnosis and expert care give patients the best chance to benefit from all available treatments.
