Abstract
This study aims at evaluation of the patterns of laryngeal carcinoma in EL-Minia governorate which concern to its prevalence, basic knowledge, nature of the disease, diagnostic aspects, therapeutic options, outcome, survival rates, and recurrence rates, and to compare the results of this study with recent studies in the literature.
Conclusion:
Differences in distribution of smoking habits and occupation according to sex were statistically significant while alcohol was not statically different. The main presenting symptoms of laryngeal carcinoma were hoarseness of voice (100%), swelling (24%), Dyspnoea (18%), and dysphagia (6%). Laryngeal mass was in the right side in 26 patients (52%), left side in 21 patients (42%), and bilateral in 3 patients (6%). Most of the laryngeal masses were located in supraglottic region in 36 patients (72%), while 7 patients (14%) had laryngeal masses in the glottic region, and 7 patients (14%) had laryngeal masses in the sub glottic region. Laryngeal masses were < 1 cm in 32 patients (64%), 1-3 cm in 14 patients (28%), and > 3 cm in 4 patients (8%). Laryngeal masses showed extension to the supraglottic region in 3 patients (6%), to the glottic region in 5 patients (10%), to the sub glottic region in 3 patients (6%), and to the related structures in one patient (2%), while 38 patients (76%) showed no extension. Lymph node enlargement was found in 17 patient (34%). These LNs were in the right side in 13 patients (26%), and in the left side in 4 patients (8%), were solitary in 2 patients (4%) and multiple (> 1) in 15 patients (30%). These LNs were upper deep cervical LNs in 12 patients (24%), and lower deep cervical LNs in 5 patients (10%).
The size of these LNs was > 1 cm in all patients (100%) with enlarged LNs.
The incidence of cancer larynx in EL-Minia governorate is within the world wide incidence. It has the same characteristics of risk factors, clinical pictures and cure rates. More attention should be paid for its epidemiological, diagnostic, curative and preventive aspects. This may be done in local national researches and projects to clarify its risk factors and find out the most suitable preventive and curative methods.
