According to a new Italian scientific study published in the Journal of Thoracic Oncology of the International Association for the Study of Lung Cancer, patients with lung cancer who quit smoking after being diagnosed with the disease have a significant improvement in survival 29% compared to those who continue to smoke despite being diagnosed.
Twenty-one articles published between 1980 and 2021 were included, which encompassed a total of over 10,000 Lung Cancer patients. There was substantial variability across studies in terms of design, patients’ characteristics, treatments received, criteria used to define smoking status (quitters or continued), and duration of follow-up.
The researchers concluded that quitting smoking at or around diagnosis is associated with a beneficial effect on the survival of Lung Cacncer patients. Treating physicians should educate LC patients about the benefits of quitting smoking even after diagnosis and provide them with the necessary smoking cessation support.
