The review also concludes that the best combination is 5-FU, one of the oldest and most commonly used chemotherapy drugs, along with powerful antibiotics called anthracyclines and a platinum-based drug called cisplatin. The benefit, however, is small and may cause a patient to experience more discomfort from the higher toxicity.
The review was conducted by Dr. Anna Dorothea Wagner of the Martin-Luther-University Halle-Wittenberg in Germany and colleagues. It appears in the April 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.
Despite recent progress, stomach cancers remain the second highest cause of cancer death worldwide, in large part because the majority of stomach cancer patients are diagnosed at a late stage of the disease when tumors are inoperable. Although small tumors can be surgically removed in the earliest stages of the disease, the only cure for advanced stomach cancer is complete removal of the stomach.
When Wagner and colleagues compared survival rates among 1,338 patients receiving combination versus single-drug care, they found that half the patients receiving combination treatment were still living seven months later, while half of those taking a single drug were still living 5.9 months later. Most of the patients in the studies were age 56 to 64.
Combination therapies were more toxic than single-drug therapies, however, so "it remains an open question, whether the benefit in survival does indeed compensate for the burden of additional toxicity to be endured by the patien
