Toripalimab Plus TPF Chemotherapy and Radiotherapy for LA-HPSCC

Study Overview
=================
Brief Summary
-----------------
TPF is the standard regime of inductive chemotherapy for squamous carcinoma of head and neck. If the primary tumor shrinks obviously (complete remission or >75% partial remission )after inductive chemotherapy, CCRT is suggested as the definitive therapy, for the tumor is sensitive to chemotherapy. If the primary tumor shrinks a little or progresses after inductive chemotherapy, operation is suggested as the definitive therapy to get a longer survival.

Detailed Description
-----------------
Inductive chemotherapy plus CCRT or operation is an option of organ preservation for patients of hypopharyngeal carcinoma. Many clinical studies have demonstrated that inductive chemotherapy plus CCRT achieved the same prognosis as total laryngectomy, and minimized the damage of normal tissue. TPF is the standard regime of inductive chemotherapy for squamous carcinoma of head and neck. If the primary tumor shrinks obviously (complete remission or >75% partial remission )after inductive chemotherapy, CCRT is suggested as the definitive therapy, for the tumor is sensitive to chemotherapy. If the primary tumor shrinks a little or progresses after inductive chemotherapy, operation is suggested as the definitive therapy to get a longer survival. This is a prospective, phase II, cohort study. We designate TPF plus Toripalimab as the inductive regime, expecting a higher complete remission rate and longer PFS and OS. And we replace the CCRT with radiation plus Toripalimab to decrease the adverse events of CCRT.
