Patients who recur in the lung while on-study and who are thought to be amenable to complete surgical resection will be able to find out if they were receiving placebo or saracatinib. Those patients who were receiving placebo may then have the option of undergoing surgical resection. If fully resected of all recurrent disease,they will be given the option of receiving oral therapy with saracatinib. Saracatinib will be administered as a once daily, oral dose of 175 mg, for a 28-day cycle, with no breaks between cycles. The duration of treatment with saracatinib will be thirteen 28-day cycles (364 days total). If complete resection of all lung nodules is not achieved, the patient will be removed from the study.
