Key Takeaways
- Chemotherapy is the standard treatment for mesothelioma. It works by disrupting the life cycles of all cells in the body — both cancerous and healthy — making it effective against cancer that has spread (metastasized) beyond a single location.
- The most widely used chemotherapy regimen for mesothelioma is pemetrexed combined with cisplatin, which has been validated through FDA approval and multiple clinical trials. Studies show that 40–50% of mesothelioma patients saw improvement in symptom management and cancer spread after pemetrexed treatment.
- Chemotherapy is a systemic treatment — it affects the entire body. This makes it effective against metastasized cancer but also causes side effects including digestive problems, hair loss, skin and mouth lesions, and fatigue.
- Doctors choose between systemic treatment (targeting the whole body) and localized treatment (targeting a specific area with surgery, specialized radiation, or cryosurgery) based on the cell type, stage, and extent of spread revealed by imaging and diagnostics.
- Not all patients are candidates for chemotherapy. Those with poor health prior to diagnosis or underlying medical complications may receive palliative care instead, because the risks of chemotherapy could outweigh its benefits.
- The decision to use chemotherapy depends on the stage, spread, cell subtype, and overall health of the patient — treatment plans are individualized.
What is Chemotherapy for Mesothelioma?
Chemotherapy is the standard for mesothelioma treatment, as it works to disrupt the life cycles of
all cells. There are different drugs with varying chemical structures and biological functions that
fall under the umbrella term of “chemotherapeutic;” if you’re interested in learning about the
technicalities of chemo differences, you can check this out. For our purposes, though, we’re
going to assume chemotherapy is one kind of “drug.” Chemotherapy refers to a class of
differently-acting drugs whose singular goal is to interfere with and stop unchecked cellular
growth.
Pemetrexed coupled with cisplatin is currently the most widely used treatment plan for
mesothelioma, as FDA approval and various clinical trials have affirmed its efficacy. In a review
study, researchers found that 40-50% of mesothelioma patients improved–in regards to symptom
management and cancer spread–after receiving a pemetrexed treatment.
Normally, chemotherapy is discussed in tandem with its side effects, including impacted
digestion, hair loss, skin and mouth lesions, and general fatigue. Despite these side effects,
though, chemotherapy is widely successful at killing cancerous cells and is still the most
common form of treatment. As doctors and researchers look towards the future of mesothelioma
care, given new treatment and diagnostic developments, the benefit-risk analysis of
chemotherapy is likely to be scrutinized.
Systemic Vs. Localized Treatment
Diagnostic and imaging techniques help visualize the cell type and spread of mesothelioma.
Depending on these findings, doctors might pursue a systemic treatment over a localized
treatment (or vice versa). For instance: if a patient has biphasic mesothelioma with minimal
metastasis, doctors might try to remove the tumors locally–healthy cells won’t be impacted. This
could look like specialized radiotherapy, surgery, or cryosurgery. If another patient has the same
diagnosis but with a significant amount of metastasis, then doctors might opt for a systemic plan,
or one that targets all bodily cells in hopes of killing the cancer cells
Do Mesothelioma Patients Need a Systemic Treatment Plan?
.
Because mesothelioma is diagnosed relatively late–its symptomatic and histological presentation
isn’t unique, and is therefore subject to differential diagnoses–treatment plans need to reflect the
stage, spread, and prognosis of its progression. For instance, if a patient had poor health prior to
diagnosis, they will likely receive palliative care instead of chemotherapy. Their bodies might
not respond well enough to chemotherapy, and the risks outweigh potential benefits.
Chemotherapy has serious ramifications for all bodily cells: it’s fantastic that cancerous cell
growth can be hampered, but it can be dangerous for healthy cells if a patient has underlying
complications. Ideally, future treatment plans will target only cancerous cells while leaving
healthy cells intact. If chemotherapy is still widely used, then certain prerequisites should be in
place prior to administration; doctors need to ensure patient safety and general health prior to
chemotherapy.

Frequently Asked Questions
What is chemotherapy and how does it treat mesothelioma?
Chemotherapy is a class of drugs designed to interfere with and stop unchecked cellular growth. Because it is a systemic treatment — affecting all cells in the body — it is effective against mesothelioma that has spread beyond a single location. Different chemotherapy drugs work through different biological mechanisms, but they share the goal of disrupting the cancer cell life cycle to slow or stop tumor growth.
What is the standard chemotherapy regimen for mesothelioma?
The most widely used chemotherapy combination for mesothelioma is pemetrexed combined with cisplatin. This regimen has been validated through FDA approval and multiple clinical trials, including a landmark study that showed the combination improved median survival from 9.3 months to 12.1 months compared to cisplatin alone. A review study found that 40–50% of mesothelioma patients showed improvement in symptom management and cancer spread after receiving pemetrexed-based treatment.
What are the side effects of chemotherapy for mesothelioma?
Because chemotherapy affects all cells — not just cancerous ones — it comes with a range of side effects:
- Digestive problems — nausea, vomiting, loss of appetite
- Hair loss
- Skin and mouth lesions
- General fatigue and weakness
- Weakened immune system — increased susceptibility to infections
Despite these side effects, chemotherapy remains the most common and broadly effective treatment for mesothelioma. Doctors carefully weigh the benefits against the risks for each individual patient before recommending a treatment plan.
What is the difference between systemic and localized treatment?
Systemic treatment — like chemotherapy — affects the entire body and is used when cancer has spread or metastasized to multiple areas. Localized treatment targets a specific area and is used when tumors are contained. Localized options include surgery, specialized radiotherapy (like IMRT), and cryosurgery. The choice between systemic and localized treatment depends on the cell type, stage, and extent of metastasis as revealed by imaging and diagnostic testing.
Who is not a candidate for chemotherapy?
Not all mesothelioma patients are suitable candidates for chemotherapy. Patients with poor overall health prior to diagnosis, significant underlying medical conditions, or compromised organ function may not be able to tolerate chemotherapy’s effects on healthy cells. In these cases, doctors typically recommend palliative care — treatments focused on managing symptoms and improving quality of life — rather than aggressive systemic treatment. The decision is always individualized based on the patient’s complete health picture.
Are there alternatives to chemotherapy for mesothelioma?
Yes. While chemotherapy remains the standard, several other treatment options are available depending on the patient’s diagnosis and health:
- Surgery — pleurectomy decortication or extrapleural pneumonectomy for resectable tumors
- Radiation therapy — IMRT or EBRT, used as adjuvant treatment or for palliative care
- Immunotherapy — checkpoint inhibitors like nivolumab and ipilimumab (CheckMate 743 trial)
- Targeted therapies and clinical trials — including vaccines, epigenetic therapies, and Tumor Treating Fields (NovoTTF)
Many patients receive a multimodal approach combining two or more of these treatments.
What should I do if I’ve been diagnosed with mesothelioma and want to understand my chemotherapy options?
If you or a loved one has been diagnosed with mesothelioma, understanding the full range of treatment options — including chemotherapy, surgery, immunotherapy, and clinical trials — is an important step.
