Brief Summary
The purpose of this prospective, single-center, single-arm, open-label II phase observation clinical trial is to evaluate the efficacy and safety of Pembrolizumab immunoadjuvant therapy in patients with stage III-IVA oral squamous cell carcinoma. The primary end point is the pathological tumor remission rate of the primary tumor and regional lymph nodes after neoadjuvant immunotherapy (pTR-2: the proportion of necrotic tumor cells, keratin fragments and giant cells in tissue sections \> 50%). The secondary endpoints are 1-year disease-free survival (DFS), 1-year overall survival (OS) and the incidence of adverse events, compared with historical data. In addition, we will check the relevant immune indicators, such as PD-L1 and CPS scores.

Outcome Measures
Primary Outcomes (1)
Rate of pathologic tumor response-2(pTR-2)
The proportion of participants with a pathologic tumor response-2(pTR-2)as assessed by the Central Pathologist at the time of definitive surgery. pTR-2 is defined as the proportion of necrotic tumor cells, keratin fragments and giant cells in tissue sections \> 50%
Up to 30 days post-sugery
Secondary Outcomes (3)
Disease-free Survival (DFS)
Up to 1 year
Overall Survival (OS)
Up to 1 year
Adverse Events (AEs)
From time of first dose of study treatment until the end of follow-up (up to 1 year)
Study Arms (1)
Pembro Neoadjuvant + SOC Adjuvant
Interventions
Participants receive 200 mg pembrolizumab as a neoadjuvant by intravenous (IV) infusion administered on Day 1 of a 21-day cycle for 2 cycles before surgery.

- Currently receiving any other investigational agents
- Has a history of allergic reactions attributed to compounds of similar chemical of biologic composition to pembrolizumab or other agents used in the study
- Patients with ongoing or active infectoin requiring systemic therapy, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, underlying pulmonary disease, or psychiatric illness/social situations that would limit compliance with study requirements
- Has a or more active autoimmune disease
- Has a history( non-infectious ) pneumonitis that required steroids or current pneumonitis
