ABSTRACT
INTRODUCTION:
Smoking cessation has been reported to benefit patients even after a diagnosis of lung cancer. We studied the smoking behavior of patients who participated in a phase 3 trial of adjuvant therapy following resection of stages IB-IIIA NSCLC.METHODS:
The ECOG-ACRIN 1505 was conducted to determine whether the addition of bevacizumab to adjuvant chemotherapy would improve overall survival (OS) for patients with early-stage NSCLC. Studying the association between smoking status and OS was a secondary end point. Patients completed a questionnaire on their smoking habits at baseline, 3, 6, 9, and 12 months.RESULTS:
A total of 1501 patients were enrolled, and 99.8%, 95%, 94%, 93%, and 93% responded to the questionnaire at baseline, 3, 6, 9, and 12 months, respectively. A total of 90% reported a current or previous history of cigarette smoking. In addition, 60% of nonsmokers at enrollment reported smoking after diagnosis (before randomization); however, 1% of them reported smoking at 12 months. Furthermore, 94% of the respondents smoked none/fewer cigarettes daily at 12 months. The incidence of grades 3-5 toxicity on treatment was 68%, 76%, and 72% in never, former, and current smokers, respectively (p = 0.05). The disease-free survival for never-smokers relative to current and former smokers was (hazard ratio [HR] 0.93, p = 0.64 and HR 1.05, p = 0.72), and OS was (adjusted HR for death 0.54, p = 0.005 and adjusted HR for death 0.68, p = 0.03), respectively.CONCLUSIONS:
This is the first comprehensive, prospective report of smoking habits in patients with NSCLC patients from a phase III early-stage trial. There was a high rate of smoking reduction and cessation following study entry. The disease-free survival did not differ significantly between smokers and never smokers, though there were less grade 3-5 toxicities and more favorable OS in never-smokers.Palavras-chave
