Background:
To analyze the prognostic value of the clinicopathological parameters of primary lesions for predicting cervical lymph node metastasis in patients with hypopharyngeal and/or supraglottic carcinoma.
Methods:
We enrolled 127 patients with squamous cell carcinomas originating in the hypopharyngeal and/or supraglottic regions.
Results:
Multivariate analysis identified the tumor depth as an independent predictive factor for lymph node metastasis (odds ratio, 4.959; 95% confidence interval, 2.290-10.739; P < 0.0001) with a predictive value of 0.966. A cutoff value of 4.5 mm was determined.
Conclusion:
The tumor depth of the primary lesion is a potent predictor of cervical lymph node metastasis in hypopharyngeal and supraglottic carcinomas. In cases with clinically negative nodal status, elective neck dissection should be adopted for patients with a tumor depth reaching 4.5 mm. Regular outpatient follow-up is recommended for patients with a tumor depth less than 1.0 mm. Close follow-up or preventative therapy should be considered between 1.0 and 4.5 mm.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
