Study: Immunotherapy better than chemotherapy in some hard-to-treat lung cancer cases

A new study concluded that immunotherapy is more effective than chemotherapy in extending the lives of some patients with advanced lung cancer. In the study, published Dec. 19 in The Lancet medical journal, researchers studied about 1,000 patients with non-small lung cancers who continued to battle tumors that had progressed despite having at least two rounds of chemotherapy.
