Background:
To investigate the relationship between paraglottic space (PGS) invasion and lymph node metastasis in patients undergoing supracricoid partial laryngectomy.
Methods:
The study included 98 subjects with squamous cell carcinoma of the glottis.
Results:
The PGS invasion rate was 60.2% (59/98), and a significant correlation was found between PGS invasion and cervical lymph node metastasis (p = .022). Fifteen of the 59 patients (25.4%) with PGS invasion, only 3 of the 39 patients (7.7%) without any evidence of PGS invasion had lymph node metastasis. Furthermore, a significant correlation was also found between PGS invasion and T classification (p < .001), vocal cord mobility (p < .001), and subglottic extension (p = .014), and patients with no evidence of PGS invasion possibly had a survival benefit (5-year disease-specific survival rate, 84% vs 64%; p = .118).
Conclusion:
This study shows that PGS invasion is significantly related to cervical lymph node metastasis in patients undergoing supracricoid partial laryngectomy.
