A recent study conducted by The University of Texas MD Anderson Cancer Center highlights the effectiveness of modifying smoking-cessation treatment for individuals struggling to quit. Published in JAMA, the study reveals that adjusting medication regimens and increasing doses significantly improves cessation rates, with varenicline demonstrating superior efficacy over combined nicotine replacement therapy (CNRT).
The double-blind, placebo-controlled trial involved 490 smokers randomized to receive either six weeks of varenicline or CNRT. Those who did not quit during the initial phase were re-randomized to continue, switch, or increase medication dosage for an additional six weeks.
Key findings from the study include:
- Smokers who failed to quit with varenicline initially were seven times more likely to quit after dose escalation.
- Switching from CNRT to varenicline resulted in nearly double the quit rate compared to maintaining the same treatment.
- Participants who received increased varenicline doses showed a 20% abstinence rate after six weeks, compared to 14% for those who switched from CNRT to varenicline or had CNRT doses increased.
- Patients who switched from varenicline to CNRT showed no improvement in quit rates.
- After six months, sustained abstinence was observed only in participants who had their varenicline doses increased.
Lead researcher Paul Cinciripini emphasized the importance of early intervention and treatment modification for smokers struggling with cessation. With tobacco use remaining the leading preventable cause of death and disease in the U.S., effective cessation strategies are crucial for improving public health outcomes.
MD Anderson's ongoing efforts to address barriers to cessation include evaluating alternative medication combinations for individuals unable to quit with initial varenicline or CNRT doses. By addressing individual and population-level challenges, such as cost, access to cessation services, and gaps in healthcare provider knowledge, MD Anderson aims to enhance smoking cessation outcomes and reduce the burden of tobacco-related illnesses.
Quitting tobacco not only improves overall health but also significantly enhances survival rates, particularly for cancer patients who smoke. As smoking cessation often involves multiple attempts, ongoing research seeks to optimize treatment approaches and support individuals in their journey towards tobacco-free living.
