Overview
Brief Summary
The goal of this observational study is to investigate the effectiveness of neoadjuvant chemoimmunotherapy (NACI) regimens in treating advanced oral squamous cell carcinoma (OSCC) patients. We analyzed clinicopathologic features of advanced OSCC patients who received PD-1 inhibitors in combination with carboplatin and paclitaxel before surgical tumor resection between 2020 and 2022. The Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) and pathologic response were used to evaluate the efficacy of the NACI treatment. Adverse events apparently related to NACI treatment were graded according to the Common Terminology Criteria for Adverse Events, version 4.0. Disease-free survival (DFS) and overall survival (OS) were calculated using the Kaplan-Meier survival curves and compared using the log rank test. Additionally, we calculated the area under curve (AUC) to compare the predictive value of PD-L1 expression with baseline serum lipid biomarkers for patient response.

Outcomes
Primary Outcomes
Overall survival (OS)
Time Frame: 2 years
The time(years) from day 1 of study treatment until death from any cause.
Disease-free survival （DFS）
Time Frame: 2 years
DFS(by months) is defined as the time from treatment until the date of the first relapse (local/regional recurrence or distant metastasis) or death (from any cause) whichever comes firsts and regardless of whether the patient withdraws from treatment or receives another anti-cancer therapy prior to disease DFS is defined as the time from treatment until the date of the first relapse (local/regional recurrence or distant metastasis) or death (from any cause) whichever comes firsts and regardless of whether the patient withdraws from treatment or receives another anti-cancer therapy prior to disease relapse.
