RATIONALE: Contingency management is a behavioral treatment approach that provides immediate rewards for positive change in behavior such as quitting smoking. In this protocol, contingency management will be in the form of a cash reward. A smoking cessation (stop-smoking) program that combines contingency management with bupropion and counseling may be effective in helping cancer survivors stop smoking.

PURPOSE: Randomized clinical trial to compare the effectiveness of bupropion and counseling with or without contingency management in helping cancer survivors stop smoking.

OBJECTIVES:

Primary

• Compare the feasibility of a multi-component smoking cessation intervention comprising bupropion and counseling with or without contingency management (cash reward) for cancer survivors who continue to smoke.
• Compare 7-day point-prevalence abstinence rates in patients treated with these smoking cessation interventions.

Secondary

• Determine the characteristics of these patients that predict success at quitting smoking.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 smoking cessation intervention arms.

• Arm I: Patients receive oral bupropion twice daily on weeks 1-12 and brief practical counseling (i.e., problem-solving strategies, stimulus control, stress management, and social support) on weeks 1-6.
• Arm II: Patients receive treatment as in arm I and contingency management (i.e., monetary reinforcement for not smoking) on weeks 1-6.

In both arms, treatment continues in the absence of unacceptable toxicity.

Patients are followed at 12 and 24 weeks after the completion of the smoking cessation interventions.

PROJECTED ACCRUAL: A total of 100 patients (50 per intervention arm) will be accrued for this study within 8 months.
