Objectives: In this study, the existence, distribution and
characteristics of cervical lymph nodes metastases in
patients with laryngeal, hypopharyngeal and intraoral
squamous cell cancer were investigated.
Patients and Methods: A retrospective review of the
charts of 81 laryngeal, hypopharyngeal and intraoral
cancer patients (10 females, 71 males; mean age 55.9
years; range 30 and 81 years) surgically treated and
followed up in Haseki Training and Research Hospital
Ear, Nose and Throat Clinic between January 2004
and October 2007 was evaluated. The demographic
data of the patients, tumor localization sites, surgical
techniques, TNM stages and regional neck metastases
Results: In laryngeal cancer patients, metastatic
lymph nodes were found in 36 of 83 (43%) neck specimens.
Patients with intraoral tumors had metastases
in six (36.4%) of 20 neck specimens. In hypopharynx
tumor patients in six of seven (85.7%) showed metastasis.
Conclusion: These results suggest that elective neck
treatment in patients with head and neck squamous
cell cancers, should include neck levels I, II, III, IV and
V. Upper aerodigestive system squamous cell cancers
have specific patterns of invasion in cervical region.
According to the localization of the primary tumor, high
risk sites of metastases were detected. Selective neck
dissections were planned according to these invasion
patterns of tumors.
