RESUMO

Introduction: Rural‒urban smoking disparities have widened in recent years because smoking prevalence reductions have been experienced disproportionately among urban adults. Tobacco cessation programs that work in urban settings may not be reaching rural smokers or may need tailoring to be effective. Identifying smoking cessation preferences and barriers among rural smokers can facilitate the implementation of acceptable programs to address rural smoking-related disparities. Thus, the aim of this study was to examine tobacco cessation motivations, preferences, and barriers among rural smokers and to assess smokers' likelihood to use various types of tobacco cessation programs. Methods: Using a cross-sectional study design, we distributed a self-administered survey to 100 smokers during regularly scheduled healthcare appointments at 3 rural Michigan practices from June to August 2019. We examined differences in participant characteristics by the readiness to quit using chi-square/Fisher's exact tests and described cessation motivations, preferences, and barriers to tobacco cessation among rural smokers. Results: Participants reporting readiness to quit were less likely to have smoking allowed in their home (31.7% vs. 75.0%; p=0.003) and had a higher prevalence of anxiety (62.1% vs. 6.3%; p=0.0001) and depression (49.2% vs. 18.8%; p=0.04) than those not ready to quit. Preferences were higher for nicotine replacement medications and reward-based approaches, with only 10% of participants being likely to use telephone-based quitlines. Conclusions: These findings suggest that provider referrals to nicotine replacement medications and reward-based approaches can be used to enhance tobacco cessation among rural smokers.

RESUMO

INTRODUCTION: A widely held misperception contends that all elderly patients, even those with good performance status (PS 0-1), are unable to tolerate aggressive chemotherapy. The objective of these analyses was to evaluate the survival and safety of treatment with pemetrexed in elderly patients with nonsquamous non-small-cell lung cancer (NSCLC) and PS 0-1. PATIENTS AND METHODS: Two randomized studies, 1 reporting the activity of pemetrexed in combination with cisplatin vs. cisplatin and gemcitabine in chemotherapy-naive patients (N = 1725) and another comparing single-agent pemetrexed with placebo in the maintenance setting (N = 663) were retrospectively considered. Data from patients with nonsquamous advanced NSCLC with PS 0-1 in these studies were evaluated in 2 separate dichotomous analyses (< 65 years and ≥ 65 years and < 70 years and ≥ 70). Cox proportional hazard models were used to estimate covariate-adjusted between-arm hazard ratios (HRs) with 95% confidence intervals for each age group. RESULTS: In the first-line study, 32.7% of the 1252 patients with nonsquamous NSCLC were ≥ 65 years and 12.8% were ≥ 70 years old. In the maintenance study, 33.1% of the 481 patients with nonsquamous NSCLC were ≥ 65 years and 16.0% were ≥ 70 years old. In both studies, the adjusted HRs for overall survival (range, 0.62-0.89) favored pemetrexed and were similar between the older and younger age groups. Dose intensity delivered and toxicities observed for patients treated with pemetrexed were manageable and similar between the older and younger age groups. CONCLUSIONS: For elderly patients with nonsquamous advanced NSCLC and PS 0-1, pemetrexed therapy, with its favorable toxicity profile, is a viable option, either in combination with cisplatin in the first-line setting or as maintenance therapy after initial chemotherapy.

RESUMO

BACKGROUND: Patients with advanced non-small cell lung cancer (NSCLC) require care that emphasizes symptom palliation in addition to extending survival. The low response rates and minimal survival gains observed in second-line studies underscore the need to assess treatment efficacy with symptomatic end points. METHODS: To characterize the relationship between patient-reported health-related quality of life outcomes and efficacy end points (tumor response, overall survival [OS], progression-free survival [PFS]), retrospective analyses were performed on Lung Cancer Symptom Scale (LCSS) data (n = 488) from the phase III study of pemetrexed (500 mg/m2 once every 3 weeks) versus docetaxel (75 mg/m2 once every 3 weeks) in advanced NSCLC. The LCSS data consisted of patient ratings of six symptoms and three summary items using 100-mm visual analogue scales. The mean maximum improvement for each item was categorized according to best tumor response, with statistical analyses based on a two-factor interaction model (with treatment arm and response group as fixed factors). Additional analyses pooled data between treatment arms and examined correlation (nonparametric and Pearson's) of time to first worsening of symptoms (TWS) with PFS and OS. RESULTS: All LCSS items, except hemoptysis, showed mean maximum improvement over baseline for responders and patients with stable disease (p < 0.01), with greater improvement associated with response. Median TWS for each LCSS item ranged between 2.3 months (fatigue) and 7.0 months (cough), with correlation between TWS and PFS and OS (all p values

RESUMO

BACKGROUND: In a recent large phase III study, previously treated patients with advanced non-small cell lung cancer who received pemetrexed demonstrated a survival time similar to patients who received docetaxel (median, 8.3 months with pemetrexed versus 7.9 months with docetaxel), with a more favorable toxicity profile, and significantly fewer Common Toxicity Criteria grade 3/4 toxicities. This is a retrospective risk-benefit analysis of survival without grade 3/4 toxicity, defined as the time to the first occurrence of Common Toxicity Criteria grade 3 or 4 toxicity or death, in the prospective phase III study comparing pemetrexed with docetaxel. METHODS: A total of 541 patients (of 571 randomized) received either pemetrexed (500 mg/m intravenously [IV]) supplemented with vitamin B12 injections and oral folic acid or docetaxel (75 mg/m IV) on day 1 of 21-day cycles. Survival without grade 3/4 toxicity was analyzed using Kaplan-Meier and Cox methods. RESULTS: Pemetrexed demonstrated a statistically significantly longer survival without grade 3/4 toxicity compared with docetaxel (hazard ratio = 0.60, 95% confidence interval: 0.50-0.72; p < 0.0001). A supportive analysis based on selected grade 3/4 toxicities (neutropenia lasting >5 days, febrile neutropenia, infection with neutropenia, anemia, thrombocytopenia, fatigue, nausea, vomiting, diarrhea, stomatitis, and neurosensory events) also demonstrated an advantage for pemetrexed (hazard ratio = 0.53; 95% confidence interval: 0.44-0.64; p < 0.0001). CONCLUSION: This analysis of survival without grade 3/4 toxicity suggests a benefit-to-risk profile that favors pemetrexed over docetaxel in the second-line treatment of patients with non-small cell lung cancer.
