Association of Imaging-Defined Deep Invasion and Tumor Volume With Clinical Cervical Lymph Node Metastasis in Hypopharyngeal Carcinoma
Objective: Deep tumor invasion is a recognized pathologic risk factor for cervical lymph node metastasis in patients with hypopharyngeal carcinoma, but the relationship between imaging findings of the primary tumor and clinical lymph node metastasis has not been fully defined. In this study, we assessed whether imaging-defined deep invasion and tumor volume are associated with clinical lymph node metastasis. Methods: This retrospective study included 142 consecutive patients with newly diagnosed hypopharyngeal squa …
