Trial Outcomes & Findings for Neoadjuvant PD-1 Blockade in Resectable Oral Squamous Cell Carcinoma (NCT NCT04649476)

NCT ID: NCT04649476

Last Updated: 2025-01-10

Results Overview

Pathologic response of resected tumors and lymph nodes to neoadjuvant PD-1 blockade alone or neoadjuvant PD-1 blockade plus TPF induction chemotherapy. Hematoxylin and eosin (H\&E)-stained slides of entire tumor and all sampled lymph nodes were scanned and assessed by two independent pathologists. The entire tumor bed and all sampled lymph nodes were examined histologically in patients who had pathological complete response (pCR), which was defined as the absence of viable tumor in all slides. MPR was defined as the presence of 10% or less viable residual tumor in the resected tumor specimens. Pathological partial response (pPR) was defined as presence of more than 10% and less than 50% viable residual tumor and pathological non-response (pNR) was defined as presence of more than 50% viable residual tumor in the resected tumor specimens. Pathologic response was defined as sum of pCR and MPR.

SECONDARY outcome

Timeframe: 8 weeks.

Radiographic response of tumors and lymph nodes to neoadjuvant PD-1 blockade alone or neoadjuvant PD-1 blockade plus TPF induction chemotherapy were evaluated by enhanced computed tomography examinations and defined by Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. Complete Response (CR) was defined as disappearance of all target lesions. Partial Response (PR) was defined as \>=30% decrease in the sum of the longest diameter of target lesions. Stable disease (SD) was defined as \<20% increase and \<30% decrease in the sum of the longest diameter of target lesions. Progressive disease (PD) was defined as \>=20% increase in the sum of the longest diameter of target lesions. Overall Response (OR) = CR + PR.
