Most lung cancer patients survived four months longer on an immunotherapy drug than those treated with chemotherapy, according to trial results published Monday.

Importantly, they also experienced fewer side-effects, researchers reported in The Lancet medical journal.

Patients with non-small-cell lung cancer -- which represents by far the majority -- survived for 13.8 months on average on the drug called atezolizumab, compared to 9.6 months for those on chemotherapy, the study authors said.
