INVESTIGATING LEVEL II-III-IV LYMPH NODES METASTASIS IN LARYNGEAL CANCER AT DA NANG HOSPITAL
Main Article Content
Abstract
Objectives: Investigating clinical, MRI, level II-III-IV lymph nodes metastasis in laryngeal cancer at Da nang hospital.
Methods: Prospective study. We describe 35 patients with laryngeal cancer who underwent laryngectomy from January 2021 to June 2023 at Da nang hospital.
Results: 35patients, 32 males, 3 female, mean age was 62.2 ± 8,9. 8,6% patients had T1a cancer, 54,1% patients had T1b cancer, 5,8% patients had T2 cancer, 28,6% patients had T3 cancer and 2,9% patients had T4 cancer. The incidence of nodal metastasis was 37,2%, of which N1 31,4%, N2a 2,9%, N2b 2,9%. MRI detected 37,2% cervical lymph nodes. In biopsy, the incidence of group III lymph node metastases 25,8%, group II 16,1% and group IV 6,5%.
Conclusion: The incidence of group III lympho node metastases was 25,8%, group II 14,2%, group IV 2,9%, which suggests that level II-III-IV neck dissection is a very important step in the laryngectomy.
