Abstract

BACKGROUND:

Tobacco smoking cessation interventions in the oncology population are an important part of comprehensive treatment plan.

OBJECTIVES:

To evaluate through a systematic review smoking cessation interventions and cessation rates in cancer patients.

SEARCH STRATEGY:

The literature was searched using Medline, EMBASE, and the Cochrane Library (inception to November 2010) by three independent review authors.

SELECTION CRITERIA:

Studies were included if tobacco smoking cessation interventions were evaluated and patients were randomized to usual care or an intervention. The primary outcome measure was cessation rates.

DATA COLLECTION AND ANALYSIS:

Two authors extracted data independently for each paper, with disagreements resolved by consensus.

MAIN RESULTS:

The systematic review found eight RCTs investigating smoking cessation interventions in the oncology patient population. Pooled relative risks were calculated from two groups of RCTs of smoking cessation interventions based on followup duration. In both groups, the pooled relative risk did not suggest a statistically significant improvement in tobacco cessation compared to usual care.

CONCLUSIONS:

Our review demonstrates that recent interventions in the last decade which are a combination of non-pharmacological and pharmacological approaches yield a statistically significant improvement in smoking cessation rates compared to usual care.
