Tobacco Smoking Cessation and Cancer Stage
Menée à partir de données américaines portant sur 729 906 patients atteints d'un cancer (âge médian : 65 ans ; 54,4 % de femmes), cette étude analyse l'association entre le statut tabagique (fumeur actuel ou ancien fumeur) et le stade du cancer au diagnostic
Tobacco smoking is a well-studied risk factor for the development of numerous malignant neoplasm types, including leukemia and bladder, colon, rectal, esophageal, kidney, laryngeal, liver, lung, mouth, pancreatic, stomach, uterine, and cervical cancer. While many oncologic studies have focused on cancer incidence, survival, and treatment implications among ongoing tobacco users, tobacco smoking cessation is another important area of investigation. Quitting tobacco smoking lowers the risk of developing the aforementioned malignant neoplasms, and tobacco smoking cessation both improves prognosis and decreases mortality risk. Yet whether cancer severity differs for former smokers has not been completely evaluated. This study examined the association between tobacco smoking status (current or former) and cancer stage.
