Mesothelioma, a rare but aggressive form of cancer that occurs in the lining of the lungs, heart and abdomen, is associated with exposure to asbestos. There is no known cure.
In the study, patients receiving pemetrexed and cisplatin ?along with the vitamin supplements folic acid and B12 ?survived nearly three months longer than patients getting cisplatin alone.
Researchers led by John Green, M.D., at the Clatterbridge Center for Oncology in England, reviewed a study of 448 patients with advanced mesothelioma who were treated with either the single drug or the combination.
"Pemetrexed used in combination with cisplatin significantly increases the length of survival, when compared with cisplatin alone," the researchers say. "Further research is needed into the optimum treatment regimen for pleural mesothelioma."
The review appears in the current issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.
The researchers examined data from a clinical trial of 20 treatment centers in Europe, the Americas, Australia and Asia. Eighty-one percent of the patients were men, with an average age of 61. Patients who received the combination treatment survived an average 2.8 months longer.
Patients receiving both medications also reported improved quality of life in terms of fatigue, loss of appetite, pain and cough.
During the early stages of the trial, patients receiving pemetrexed had serious symptoms of toxicity, including drug-related death. Other side effects included blo
