Abstract
Introduction
Head and neck cancer is the commonest cancer among male patients & third commonest cancer
in females in a study done at Tikur Anbessa specialized hospital but there is no research done to
assess imaging patterns of laryngeal cancer and this is the first study done at Tikur Anbessa
specialized hospital as well as in Ethiopia to assess imaging patterns of laryngeal cancer.
Methods
Hospital based descriptive cross-sectional study was used at Tikur Anbessa specialized hospital
from 2016-2019. The study participants were all patients with laryngeal mass who came to
oncology department & radiology department at TASH. Data was collected from cancer registry
in the oncology department as well as by reviewing imaging reports of patients with laryngeal
mass who came to radiology and oncology department using structured questionnaire. The data
was analyzed using SPSS software version 24.4 and results presented using text, tables and
graphs.
Result
The study showed that of the 90 patients who were included in the study had age range from 24
yrs. to a maximum of 85 yrs. with a mean age of 51.5 years with (±14 SD).
77 (85.6% presented with hoarseness of voice and Among those 34 cases for which risk factors
were specified 23 (67.6%) had cigarette smoking as risk factor while 12 (35.3%) had alcohol as
risk factor.
Out of the 79 cases with laryngeal sub sites described, 38 (48.1%) were transglottic, 27 (34.2%)
glottic and 12 (15.2%) were supraglottic.
46 (51.1%) patients had extra laryngeal spread, 18 (20%) had no extra laryngeal spread, and for
26 (28.9%) cases it was not specified.
Laryngoscopic cases of glottic location correlates with 46.2% of imaging cases of glottis
cancer with the rest 46.2% being transglottic and 7.7% being supraglotic on imaging.
