Researchers looked at 250 lung cancer patients who were smokers and were referred to a program to help them stop smoking. Fifty had recently quit smoking, and 71 had quit smoking soon after being referred to the tobacco cessation program.
Those who quit smoking shortly before or after they learned they had lung cancer lived an average of 28 months. Those who continued to smoke lived an average of 18 months, the study found.
The researchers also found that patients who didn't quit smoking but continued their attempts to quit may also live longer. However, death rates for those who quit and then started smoking again were similar to those who didn't quit.
"To our knowledge, this is one of the first studies to examine the impact of tobacco cessation on survival among lung cancer patients who participated in a mandatory assessment and automatic referral to a tobacco cessation service," study senior author Mary Reid, director of cancer screening and survivorship, at Roswell Park Cancer Institute in Buffalo, N.Y., said in an institute news release.
"Establishing services to accurately screen for tobacco use and easily accessible cessation programs are essential in the cancer care setting to further improve the survival time and quality of life of patients," Reid said.
