 PHASE II preoperative component: Patients who are surgical candidates may opt to undergo surgical resection of the tumor. Beginning 5-7 days before surgery, these patients receive oral erlotinib once daily until surgery. Patients also receive temsirolimus IV over 30 minutes at the MTD and then undergo surgical resection of the tumor 3-24 hours later. Beginning 2-4 weeks after surgery, patients receive temsirolimus at the MTD and erlotinib as in phase I.
