What Are the Side Effects of Mesothelioma Treatment?

Surgery Side Effects and Complications

Major mesothelioma surgeries such as EPP and P/D carry significant risks given their scope. Common postoperative complications include respiratory issues such as pneumonia or respiratory failure, cardiac arrhythmias (particularly atrial fibrillation), blood clots including deep vein thrombosis and pulmonary embolism, wound infection, and prolonged air leak from the lung surface.

After EPP, patients must adapt to breathing with one lung, which reduces exercise capacity. After P/D, patients may experience persistent pleural effusion requiring drainage. Palliative procedures such as thoracentesis and pleurodesis carry lower risks but may still cause pain, infection, or pneumothorax.

Chemotherapy Side Effects

Chemotherapy side effects result from the drugs’ effects on rapidly dividing healthy cells. The most common side effects of pemetrexed-cisplatin include fatigue, nausea and vomiting (managed with anti-emetic medications), decreased blood cell counts (neutropenia, anemia, thrombocytopenia), peripheral neuropathy (tingling or numbness in hands and feet), and kidney toxicity (primarily from cisplatin).

Folic acid and vitamin B12 supplementation, which are required during pemetrexed treatment, significantly reduce the severity of side effects. Patients receiving carboplatin instead of cisplatin generally experience less kidney toxicity and nausea but may have more bone marrow suppression. Most chemotherapy side effects improve within weeks after treatment ends.

Radiation Side Effects

Radiation therapy side effects depend on the treatment area, dose, and duration. Acute side effects include fatigue (the most common complaint), skin changes ranging from mild redness to peeling, esophagitis causing painful swallowing, and radiation pneumonitis presenting as cough and shortness of breath weeks to months after treatment.

Long-term radiation effects are less common but may include pulmonary fibrosis (scarring of lung tissue), rib fractures in the treated area, and cardiac effects if the heart was within the treatment field. Modern radiation techniques such as IMRT help minimize these risks by precisely targeting the tumor.

Immunotherapy Side Effects

Immunotherapy side effects differ fundamentally from those of chemotherapy. Because checkpoint inhibitors work by activating the immune system, their side effects are primarily autoimmune in nature — the overactivated immune system may attack healthy tissues. Common immune-related adverse events include skin rashes, colitis (diarrhea), hepatitis (liver inflammation), pneumonitis (lung inflammation), and thyroid dysfunction.

Most immune-related side effects are manageable and reversible when detected early. Treatment teams monitor patients closely with regular blood tests and symptom assessments. Severe reactions may require temporary treatment interruption and corticosteroid therapy.

Managing Side Effects and Getting Support

Proactive side effect management is essential to quality of life during mesothelioma treatment. Patients should report any new symptoms promptly to their medical team. Supportive care measures include anti-nausea medications, growth factors for low blood counts, pain management, nutritional counseling, and psychological support. Resources for patients and families can help navigate the emotional and practical challenges of treatment.

The financial toll of managing side effects adds to the overall cost of mesothelioma treatment. Compensation from asbestos exposure can help cover these expenses, including medications, home care, and lost income during treatment.
