Conditions

Stage III-IVA Resectable Locoregionall Advanced Head and Neck Squamous Cell Carcinoma (LA-HNSCC)

Brief summary

MPR as assessed by external independent pathology review (IPR) is defined as ≤10% invasive squamous cell carcinoma (SCC) within the resected primary tumor specimen and all sampled regional lymph nodes
