Experts: Smoking Status Crucial in Cancer Trials to Improve Survival
Doctors from around the world are saying that when people with cancer join studies for new treatments, it's really important to know if they smoke.
Smoking can make cancer treatments not work as well and make people less likely to survive.
Reports have shown that smoking makes cancer worse.
Quitting smoking can help people live longer after a cancer diagnosis, sometimes even more than the treatments themselves.
However, studies often don't ask about smoking, making it hard to understand how treatments work.
Doctors want to change this so that they can help people with cancer as much as possible.
Experts urge recording smoking status in cancer trials, as tobacco use reduces treatment efficacy.
The 2014 US Surgeon General's report linked smoking to adverse cancer outcomes and higher mortality.
Continued smoking worsens outcomes for patients undergoing surgery, radiotherapy, or systemic therapies.
Quitting smoking after a cancer diagnosis can lead to longer survival rates.
Lack of standardized tools and resources hinders consistent smoking data collection in trials.
