[Clinical-pathological characterization of laryngeal cancer in the Mexican population].

BACKGROUND

Cancer of the larynx occupies the first frequency site of cancer of the upper digestive tract and represents 42% of malignant neoplasms of the upper aero-digestive tract. It is a potentially curable entity if it is diagnosed in early stages.

OBJECTIVE

Characterize the clinical pathological features of patients with laryngeal cancer, which can serve as a guide for diagnostic suspicion in primary and secondary care.

METHOD: Descriptive study. All the records of patients with an initial diagnosis of primary laryngeal carcinoma undergoing direct micro-laryngoscopy plus biopsy from January 1, 2014 to December 31, 2018 were analyzed.

RESULTS

173 new cases of laryngeal carcinoma were diagnosed, the male sex predominated (86%). With an average age of presentation of 65 ± 11 years and a history of smoking in 78.6% (n 136). Dysphonia was the initial symptom in 81% (140) of the patients.

CONCLUSIONS

The profile of the patient with laryngeal cancer corresponds to a patient older than 60 years, male, a history of smoking and a history of dysphonia greater than 30 days. Clinically, we will find an epithelial epidermoid moderately differentiated tumor limited to the glottis.
