Real-world Analysis on the Efficacy and Safety of Neoadjuvant Therapy for Head and Neck Squamous Cell Carcinoma （neoHNSCC）

Study Overview
=================
Brief Summary
-----------------
This is a retrospective, single-arm study that assesses the efficacy and safety of neoadjuvant immunotherapy combined with platinum-based chemotherapy for Head and Neck Squamous Cell Carcinoma. This trial will also explore the biomarkers of neoadjuvant immunochemotherapy.

Detailed Description
-----------------
This is a retrospective, single-arm study that assesses the efficacy and safety of neoadjuvant immunotherapy combined with platinum-based chemotherapy for Head and Neck Squamous Cell Carcinoma. This trial will also explore the biomarkers of neoadjuvant immunochemotherapy. Patients with untreated, operable, or potentially resectable HNSCC will be included.The pathological results, adverse events and other information of eligible patients will be collected.
