The chemotherapeutic drug gemcitabine is most often used to treat pancreatic, ovarian and breast cancers. Doctors also found success treating pleural and peritoneal mesothelioma and certain types of lung cancer. It's often used in combination with another chemotherapy drug.

Gemcitabine is a chemotherapy drug. It blocks DNA replication in cancer cells to slow pleural mesothelioma. Scientists at Eli Lilly discovered it and marketed it as Gemzar for injection.
Before starting gemcitabine, patients must inform their doctor of any medications they take. This includes all prescriptions, vitamins, supplements, and OTC drugs.

Patients with mesothelioma may do well on gemcitabine. This drug is often used for people who can’t tolerate platinum drugs, like cisplatin or carboplatin.
Gemcitabine chemotherapy is usually done on an outpatient basis. It’s given via IV. Treatment typically involves a trip to a doctor’s office, clinic or hospital. The procedure usually takes a few hours. The drug administration lasts about 30 minutes.
It’s usually given on various schedules. The most common is once a week for 3 weeks, then 1 week off. Your cancer doctor will set the best treatment length and dosage for you.
Gemcitabine, or Gemzar, is a chemotherapy drug for mesothelioma. It can be used alone or with platinum drugs. Gemcitabine is often more effective as a second- or third-line option after other treatment options have failed.
The drug may be given alone or with another chemo agent or anti-cancer drugs. It may be used in first-line or second-line chemotherapy regimens for mesothelioma. The FDA has approved gemcitabine for breast, ovarian, pancreatic and non-small cell lung cancers.
First-line chemotherapy with gemcitabine often combines it with another drug, like cisplatin. This drug may be given as second-line chemo. It can be used alone or in combination, depending on the patient’s response to first-line chemo. Gemcitabine is used more in second-line chemo for mesothelioma than in first-line. This is because cisplatin and pemetrexed have better survival rates.
Pairing gemcitabine with other anti-cancer drugs improves outcomes for people with mesothelioma. Recent research on gemcitabine for mesothelioma combines it with immunotherapy, as well as with targeted and gene therapies.
Gemcitabine has helped many people with pleural mesothelioma. It eased symptoms like chest pain, cough and shortness of breath. It can also help delay cancer growth and progression for some patients. A study in the Journal of Thoracic Oncology found that gemcitabine could nearly double progression-free survival after first-line treatment.
Chemotherapy aims to slow or kill the rapidly growing cancer cells in the patient. However, those agents that are used can sometimes also kill rapid growing healthy cells. I always encourage patients to understand that there may be side effects, but not all the time.
The most common side effects of gemcitabine are nausea and flu-like symptoms. It also increases the risk of infection.
Chemotherapy drugs can harm the immune system. They kill specific immune cells. If you take gemcitabine for mesothelioma, avoid people who might be sick. They may have colds or other infections. A medical face mask may be worn to protect you from contact with germs.
Gemcitabine Side Effects
Those with impaired liver or kidney function shouldn’t use gemcitabine. It can cause severe liver and kidney damage.
Gemcitabine and most chemotherapy drugs can also harm unborn babies. Pregnant women should discuss their options with their doctors.

Several phase II clinical trials have investigated gemcitabine’s effectiveness on mesothelioma. Some phase II trials report higher response or overall survival rates than others. Despite inconsistent results, the consensus is that the drug benefits people with mesothelioma.
An active 2024 clinical trial is testing a mix of gemcitabine and ramucirumab for mesothelioma. This is after disease progression on platinum and pemetrexed chemotherapy. Early results show ramucirumab plus gemcitabine is better than gemcitabine plus placebo. It improved overall survival and had a good safety profile.
The results [of a 2021 study] show that the addition of ramucirumab to gemcitabine can provide a notable improvement in overall survival. This combination could be a new option in this setting.
Past studies have tested variables such as prolonged low-dose administration vs. typical doses and length. A 6-hour low-dose was one of the longest reported times for chemotherapy and was more effective than 30-minute infusions. Another study combined gemcitabine and cisplatin, which shrank tumors more than 30%. However, mesothelioma expert Dr. Hedy Kindler led a trial testing a gemcitabine, cisplatin and bevacizumab combo with results not significant enough to warrant further study.
Studies continue to investigate the best ways to administer gemcitabine to treat mesothelioma. The drug may work better with other chemotherapy drugs, targeted therapies or nutrition. Trials are ongoing to improve outcomes for patients.
