Study Arms:
- Intervention group (varenicline and behavioral intervention) (Type: EXPERIMENTAL): Patients receive varenicline PO QD on days 1-3 and BID on days 4-84 for 12 weeks in the absence of disease progression or unacceptable toxicity. Patients also complete behavioral intervention consisting of no smoking message from surgical team member and how to use NCI quitline at surgical consult.
- Control group (placebo and behavioral intervention) (Type: PLACEBO_COMPARATOR): Patients receive placebo PO QD on days 1-3 and BID on days 4-84 for 12 weeks in the absence of disease progression or unacceptable toxicity. Patients also complete behavioral intervention consisting of no smoking message from surgical team member and how to use NCI quitline at surgical consult.

Based on this trial design, predict the completion outcome and termination type (if applicable).
