Executive Summary
Chemotherapy is a cornerstone of mesothelioma treatment and, for many patients, the primary treatment. It uses drugs that circulate through the bloodstream to kill cancer cells throughout the body, making it especially important for a cancer like mesothelioma that spreads along the lining of the lung or abdomen and is often not fully removable by surgery.[1]
The standard first-line regimen combines a platinum drug — cisplatin (or carboplatin) — with pemetrexed. According to PubMed, the landmark 2003 phase III trial that established this combination found that pemetrexed plus cisplatin extended median survival to 12.1 months versus 9.3 months with cisplatin alone, with a response rate of 41.3% versus 16.7%.[2] That trial reshaped mesothelioma care and made pemetrexed/platinum the global standard of care for two decades. Adding folic acid and vitamin B12 significantly reduces the toxicity of pemetrexed.[2]
Chemotherapy is used in several settings: as the main treatment for patients who cannot have surgery, before or after surgery in combination approaches, and increasingly alongside or compared with immunotherapy, which is now a first-line option for some patients.[3] For peritoneal mesothelioma, chemotherapy is often delivered directly into the abdomen during surgery, and newer approaches such as pressurized intraperitoneal aerosol chemotherapy (PIPAC) are being studied for abdominal disease.[4] Regardless of the treatment plan, a mesothelioma diagnosis carries full rights to compensation, and treatment costs are recoverable as damages.[5]
At-a-Glance
Mesothelioma chemotherapy at a glance:
- Cisplatin + pemetrexed is the standard first-line regimen — established by a landmark 2003 phase III trial and used worldwide for two decades[2]
- Median survival reached 12.1 months in the pivotal trial — versus 9.3 months with cisplatin alone, a statistically significant improvement[2]
- Combination response rate was about 41% — versus 17% for single-agent cisplatin[2]
- Carboplatin can replace cisplatin — for older or less-fit patients, carboplatin plus pemetrexed is gentler with similar benefit[1]
- Vitamin supplementation reduces side effects — folic acid and vitamin B12 significantly cut pemetrexed toxicity without reducing its benefit[2]
- Chemotherapy is given intravenously every 21 days — typically for four to six cycles, then reassessment[6]
- Immunotherapy is now a first-line alternative for some patients — nivolumab plus ipilimumab extended survival versus chemotherapy in a phase 3 trial, especially for non-epithelioid disease[3]
- Peritoneal mesothelioma often uses heated chemo in the abdomen — cytoreductive surgery with HIPEC delivers chemotherapy directly to the abdominal cavity[7]
- Chemotherapy does not change legal rights — treatment costs are recoverable as damages in an asbestos claim[5]

How Does Chemotherapy Treat Mesothelioma?
Chemotherapy uses cytotoxic drugs to kill rapidly dividing cancer cells. Because it travels through the bloodstream, it reaches cancer cells throughout the body — an advantage for mesothelioma, which grows as a diffuse rind along the pleura or peritoneum rather than as a single removable mass.[1] This systemic reach is why chemotherapy is the primary treatment for patients whose disease cannot be completely removed by surgery.
Chemotherapy is used in several roles. As first-line therapy, it is the main treatment for unresectable disease. As part of multimodal therapy, it may be given before surgery (neoadjuvant) to shrink tumors or after surgery (adjuvant) to kill remaining cells. And in peritoneal mesothelioma, chemotherapy is often delivered directly into the abdomen as heated intraperitoneal chemotherapy during surgery — see Pleural vs Peritoneal Mesothelioma.[7]
What Is the Standard Chemotherapy Regimen for Mesothelioma?
The standard first-line regimen pairs a platinum drug with pemetrexed (brand name Alimta). According to PubMed, the pivotal 2003 phase III trial randomly assigned 456 patients to pemetrexed plus cisplatin or cisplatin alone. Median survival was 12.1 months with the combination versus 9.3 months with cisplatin alone, time to progression improved to 5.7 months, and the response rate more than doubled to 41.3%.[2] This established pemetrexed plus cisplatin as the standard of care and remains a foundation of treatment today. See also Pemetrexed.
For patients who are older or have reduced kidney function or performance status, carboplatin is frequently substituted for cisplatin. Carboplatin plus pemetrexed is better tolerated and produces comparable outcomes in routine practice, making it a common real-world choice.[1] An important refinement from the original trial: adding folic acid and vitamin B12 significantly reduced the toxicity of pemetrexed without reducing its survival benefit, and vitamin supplementation is now standard.[2]
How Is Chemotherapy Given, and What Are the Side Effects?
Chemotherapy for mesothelioma is given intravenously, typically on a 21-day cycle, for four to six cycles before doctors reassess the response with imaging.[6] Treatment is usually delivered in an outpatient infusion center.
Common side effects reflect chemotherapy's impact on healthy fast-dividing cells: fatigue, nausea, low blood counts (which raise infection and bleeding risk), and kidney effects with cisplatin. Modern supportive care — anti-nausea medication, growth factors, hydration, and the folic acid and B12 supplementation described above — makes these regimens far more tolerable than in the past.[2][6] Some patients also experience "chemo brain" — temporary changes in memory, concentration, and the ability to think clearly during and after treatment — which usually improves over time with rest, routine, and support.[8] Patients should report side effects promptly so doses can be adjusted.
How Does Chemotherapy Fit With Surgery and Immunotherapy?
Chemotherapy is one part of a broader treatment landscape. In selected patients with resectable disease, it is combined with surgery — see Mesothelioma Surgery — either before or after the operation, and for Epithelioid Mesothelioma this multimodal approach offers the best outcomes.
The rise of immunotherapy has reshaped first-line choices. According to PubMed, the CheckMate 743 phase 3 trial found that nivolumab plus ipilimumab extended median survival to 18.1 months versus 14.1 months with chemotherapy, with the largest benefit in non-epithelioid disease.[3] As a result, some patients now begin with immunotherapy rather than chemotherapy, while chemotherapy remains central for many others — particularly those with epithelioid histology. See Mesothelioma Immunotherapy. The right sequence depends on cell type, fitness, and individual factors, and is decided with a mesothelioma specialist.
Does Chemotherapy Affect a Mesothelioma Legal Claim?
No. Chemotherapy is a medical decision, not a legal one, and undergoing it does not change a patient's rights. A confirmed mesothelioma diagnosis establishes eligibility for asbestos trust fund claims, lawsuits, and VA benefits.[5][9] Importantly, the cost of chemotherapy and related care is recoverable as damages in an asbestos claim, along with lost income and pain and suffering.[10] Keeping records of treatment and expenses strengthens a claim.

Frequently Asked Questions
What is the standard chemotherapy for mesothelioma?
The standard first-line regimen is a platinum drug (cisplatin or carboplatin) combined with pemetrexed. This combination was established by a landmark 2003 phase III trial and remains a foundation of treatment.[2]
How much does chemotherapy extend survival in mesothelioma?
In the pivotal trial, pemetrexed plus cisplatin extended median survival to 12.1 months versus 9.3 months with cisplatin alone, and more than doubled the response rate to about 41%.[2] Outcomes vary widely by cell type, stage, and overall health.
What is the difference between cisplatin and carboplatin?
Both are platinum drugs. Cisplatin is more potent but harder on the kidneys and causes more nausea; carboplatin is gentler and often used for older or less-fit patients, with comparable real-world results.[1]
What are the side effects of mesothelioma chemotherapy?
Common side effects include fatigue, nausea, low blood counts, and kidney effects with cisplatin. Folic acid and vitamin B12 supplementation significantly reduces pemetrexed toxicity, and supportive medications manage most other effects.[2][6]
Is chemotherapy or immunotherapy better for mesothelioma?
It depends on the patient. Immunotherapy with nivolumab plus ipilimumab extended survival versus chemotherapy in a phase 3 trial, especially for non-epithelioid disease, while chemotherapy remains central for many patients with epithelioid histology. The choice is individualized.[3]
Does chemotherapy cost affect my compensation?
The cost of chemotherapy and related medical care is recoverable as damages in an asbestos claim, in addition to lost wages and pain and suffering. A mesothelioma diagnosis qualifies for compensation regardless of treatment choices.[5][10]
