Lung cancer expert Dr. Klaus Kirchbacher from the Wilhelminenspital hospital in Vienna said the condition had previously been treated via chemotherapy, that could reduce the tumor burden in 30 to 40 percent of cases, and stabilize the disease in a further 40 percent of persons. Despite this, only 30 to 40 percent of patients lived a year past their initial diagnosis.

From about 2010 onwards there has been a shift toward more personalized therapies, he said, and while an improved response rate has been observed compared to chemotherapy treatment, only about 15 percent of people with advanced forms of lung cancer are suited to such a treatment.

Most notable is also that the majority of these people have never smoked, Kirchbacher said.

His hospital colleague and fellow expert Dr. Meinhard Kneussl said the "most sensible and effective measure" to reduce the mortality rate, the avoidance of smoking, is not stressed enough.

He said about 80 percent of lung cancer cases are connected to the habit, and added that it is never too late to quit smoking and thereby reduce the risk of cancer.
