Phase I/II Study of Postoperative Adjuvant Chemoradiation for Advanced-Stage Cutaneous Squamous Cell Carcinoma of the Head and Neck (cSCCHN)

This phase I/II trial studies the side effects and best dose of linsitinib when given together with erlotinib hydrochloride and radiation therapy after surgery in treating patients with advanced or recurrent head and neck cancer. Erlotinib hydrochloride and linsitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy together with erlotinib hydrochloride and linsitinib may kill more tumor cells. Giving these treatments after surgery may kill any tumor cells that remain after surgery.
