Pretreatment Primary Tumor SUVmax Measured by FDG-PET and Pathologic Tumor Depth Predict for Poor Outcomes in Patients With Oral Cavity Squamous Cell Carcinoma and Pathologically Positive Lymph Nodes

The combination of the primary tumor SUVmax (≥19.3) and pathologic tumor depth (≥12 mm) identified a subgroup of OSCC patients at greatest risk of poor LC and death.
