Bottom Line

A multicenter randomized controlled trial demonstrating that a virtual sustained tobacco treatment program consisting of telehealth counseling and nicotine replacement therapy significantly increased 6-month smoking quit rates compared to standard quitline referral among recently diagnosed cancer patients in community oncology settings.

Key Findings

1. A total of 306 recently diagnosed patients with cancer (70.9% female, 86.3% White, median age 57 years) who currently smoked were randomly assigned across 37 NCI Community Oncology Research Program (NCORP) community sites.
2. Patient-reported 7-day point prevalence abstinence at 6 months was nearly double in the virtual sustained treatment (VST) group at 28.4% (42 of 148) compared to 14.7% (21 of 143) in the enhanced usual care (EUC) group (OR 2.3 [99.8% CI, 1.07 to 4.97], P = .005).
3. At 3 months, 7-day point prevalence abstinence was 24.7% (38 of 154) for the VST group and 15.0% (22 of 147) for the EUC group.
4. Engagement in the telehealth intervention was robust: 80.8% (126 of 156) of VST participants engaged in counseling, and 85.7% (108 of 126) of those were dispensed nicotine replacement therapy (NRT).
5. A significant dose-response effect was observed in the intervention arm: VST participants who completed more than 8 counseling sessions were much more likely to be abstinent at 6 months compared to those who completed 1 to 4 sessions (46.4% vs. 13.3%; OR 4.91 [95% CI, 1.78 to 13.54]).

Setting
Multicenter, US
Population Recently diagnosed English- and Spanish-speaking adult patients with cancer who currently smoke tobacco.
Intervention Virtual sustained treatment (VST) comprising up to 11 synchronous telehealth counseling sessions (weekly, biweekly, and then monthly) plus up to 12 weeks of free nicotine replacement therapy (NRT).
Comparator Enhanced usual care (EUC) comprising a referral to the National Cancer Institute (NCI) quitline.
Outcome Patient-reported 7-day point prevalence smoking abstinence at 6 months.

Study Limitations

The study cohort lacked racial and ethnic diversity (86.3% White), which may limit the generalizability of the findings to broader and more diverse demographic populations.
The primary outcome relied on patient self-reported point prevalence abstinence without routine biochemical confirmation, introducing the possibility of social desirability or self-reporting bias.
Participants were individuals willing to enroll in a multi-session telehealth study, potentially introducing selection bias toward patients who were already highly motivated to quit smoking or those possessing adequate digital literacy and broadband access.
Follow-up was limited to 6 months; longer-term follow-up is necessary to evaluate lifelong sustained cessation and relapse rates in this high-risk population.

Clinical Significance

The Smokefree Support Study 2.0 demonstrates that integrating virtual, sustained counseling alongside free nicotine replacement therapy into community oncology settings is both practical and highly efficacious. This scalable telehealth framework addresses a critical gap in comprehensive cancer care, offering a robust, evidence-based model to deliver necessary tobacco cessation support to high-risk patients directly in their communities, regardless of geographic barriers.

Historical Context

Continuing to smoke following a cancer diagnosis is strongly associated with increased treatment toxicities, higher risks of secondary malignancies, diminished therapeutic efficacy, and decreased overall survival. Recognizing this, initiatives like the NCI Cancer Center Cessation Initiative (C3I) and the American College of Surgeons Commission on Cancer established standards for universal tobacco screening and treatment. However, the robust integration of these cessation services historically lagged in community oncology practices where the majority of patients in the US receive care. Building upon earlier efficacy studies of intensive behavioral counseling, the EAQ171CD trial was designed to bridge this implementation gap by testing a proactive, telehealth-based model uniquely optimized for scalability across the national community-based NCORP network.

Guided Discussion

High-yield insights from every perspective

Med Student
Medical Student

How does continued tobacco use pathophysiologically impact the efficacy and toxicity of systemic cancer therapies, and why does this make intensive cessation interventions critical for patients recently diagnosed with cancer?

Key Response

Continued smoking can induce hepatic CYP450 enzymes (e.g., CYP1A2), increasing the clearance of certain chemotherapeutics like erlotinib or irinotecan, thereby reducing their efficacy. It also increases tissue hypoxia which reduces the efficacy of radiotherapy, and exacerbates pulmonary, wound healing, and cardiovascular toxicities, underscoring the urgent need for cessation at diagnosis.

When initiating Nicotine Replacement Therapy (NRT) in a newly diagnosed cancer patient who smokes 1.5 packs per day, what is the optimal initial NRT strategy according to current best practices, and how does the virtual counseling component complement this medical management?

Key Response

Evidence supports combination NRT (a long-acting patch for baseline craving control plus a short-acting form like gum or lozenge for breakthrough cravings) rather than monotherapy. Virtual counseling complements this by improving adherence to the NRT regimen, managing side effects in real-time, and addressing behavioral triggers, overcoming the notoriously low adherence rates seen with standard quitline referrals.

Given that cancer patients often face overwhelming treatment burdens and frequent clinic visits, how does a virtual, sustained tobacco treatment model mitigate the 'competing demands' barrier commonly seen in oncology practices compared to standard proactive quitline referrals?

Key Response

Standard quitlines often fail in oncology because they operate in a silo, requiring patients to coordinate extra care during an overwhelming cancer diagnosis. A sustained, integrated virtual model proactively delivers continuous behavioral support and medication management without adding travel burden, effectively integrating cessation into the longitudinal continuum of cancer care.

If we adopt the ECOG-ACRIN EAQ171CD virtual sustained model in our community oncology practice, what structural changes are required to shift our current 'ask and advise' workflow to an 'opt-out' integrated virtual treatment model, and what are the clinical workflow implications?

Key Response

Shifting from standard quitline referral to integrated virtual sustained treatment requires EHR integration for automatic referrals (opt-out), establishing telehealth workflows for counseling, and ensuring dedicated staff can manage longitudinal NRT prescribing and follow-up without disrupting standard oncology workflows. It requires viewing cessation as a concurrent cancer treatment rather than a primary care preventive measure.

In evaluating the ECOG-ACRIN EAQ171CD trial, how does the choice of standard quitline referral as an active control, rather than standard-of-care 'usual practice', impact the interpretation of the effect size, and what statistical methods are necessary to account for cluster effects in community oncology (NCORP) settings?

Key Response

Using an active control (quitline) instead of 'usual care' (often just brief advice) sets a higher bar for superiority, meaning the observed effect size is likely a conservative estimate of real-world benefit. Furthermore, as a multicenter NCORP study, mixed-effects models or generalized estimating equations (GEE) are essential to account for intra-cluster correlation among patients treated at the same community site.

As a peer reviewer, how would you critically evaluate the study's reliance on self-reported 6-month quit rates versus biochemically verified abstinence, particularly in a population of recently diagnosed cancer patients where social desirability bias might be exceptionally high?

Key Response

A rigorous reviewer would flag that cancer patients may underreport smoking due to stigma or fear of judgment from their oncologists (social desirability bias). While biochemical verification (e.g., cotinine, exhaled CO) is the gold standard, it is logistically challenging in a virtual, multicenter community trial. The study must adequately address whether the magnitude of the difference between arms could be entirely explained by differential misclassification.

Guideline Committee
Guideline Committee

How should the findings of the EAQ171CD trial influence the next iteration of ASCO and NCCN guidelines regarding the recommended standard of care for tobacco cessation delivery in community oncology, and does this evidence upgrade the strength of recommendation for telehealth-based continuous interventions?

Key Response

Current NCCN guidelines strongly recommend combination pharmacotherapy and behavioral counseling, but practical implementation remains poor. This RCT provides Level 1 evidence that virtual, sustained, integrated treatment outperforms standard quitlines. The committee should consider upgrading recommendations to explicitly advocate for dedicated virtual longitudinal cessation programs over passive quitline referrals as the preferred care delivery model in community oncology settings.
