(STRASBOURG, France) -- Lung cancer is the number-one cause of cancer deaths in the United States.
Now, a new study in the journal Lancet Oncology finds that a lung-cancer vaccine could be on the way.
Researchers at the Université de Strasbourg in Strasbourg, France, divided 148 lung cancer patients into two groups. One group got chemotherapy plus a new cancer vaccine called TG4010. The rest were given chemotherapy alone.
After six months, 43 percent of those who got both treatments had slower progression of their cancer, compared to 35 percent of those who had only chemotherapy. Overall, survival was similar in both groups.
The study found that the combination therapy worked better in patients who had normal levels of so-called "natural killer cells" that work to kill cancer cells and keep healthy cells alive.
Another trial study is now underway.
