Main objective: To evaluate the role of High - Resolution U/S in detecting metastatic
neck nodes metastases in patients with head and neck cancer.
Study design: Descriptive Cross - Sectional Study
Setting: Kenyatta National Hospital - Nairobi
Methods and materials: Patients with head and neck cancer presenting at Ear, Nose and
Throat, Head and Neck Surgery Department - Kenyatta National Hospital, were evaluate
for cervical lymphadenopathy by physical, examination, contrast enhanced CT
and U/S. The neck findings were correlated with cytopathological findings of lymph
node biopsies.
Results: A total of 152 consecutive patients were included in the study 111(73%)
patients were males and 41 (27%) were females. The mean age ratio was 54.9 years.
General examination and detailed otolaryngological evaluation was done. Neck findings
were documented patients were also evaluated using contrast- enhanced CT & U/S 69
patients underwent FNA biopsy of neck nodes. 71 (46.7%) of the patients had palpable
clinical lymph nodes, 59 out of 69 patients done FNA were confirmed to have metastatic
nodes. CT detected nodes in 54(35.5%) patients; 48 out of the 54 patients were noted to
have metastasis after FNA cytology. U/S detected lymph nodes in necks of all patients
had nodes which exhibited features of metastasis. 55 (36.2%) patients were correctly
diagnosed with nodal metastasis on U/S. Overall agreement between cytopathological
findings and PIE, CT, and-U/S IN detecting neck nodal metastasis was 85.5%, 8l.4%,
and 93.6% respectively.
CONCLUSION
U/S proved more accurate in staging cervical lymph node metastases compared with PIE
and CT
