Epidemiological Analysis of Patients with Malignant Neoplasm of Larynx at São Jose Avaí Hospital
Introduction: The larynx is considered the largest site of occurrence of neoplasm in the head and neck, and deserves special assessment. It is more common in men between the sixth and seventh decades of life. More than 90% are squamous cell carcinomas and are directly associated with smoking and alcohol consumption.
Objective: Epidemiological study of patients with malignant neoplasm of the larynx treated at São Jose do Avai hospital from October 2012 to October 2013.
Methods: A retrospective study was conducted through pathological reports of patients submitted to larynx microsurgery with a diagnosis of malignancy, evaluated by a questionnaire and the results expressed as graphs.
Results: The results were evaluated for a total of 25 patients, 23 of whom were diagnosed with histopathologic squamous cell carcinoma, 1 with metastatic cancer, and 1 with a diagnosis of adenoid cystic carcinoma. The average age of these patients was 63 years, mostly male, smokers (20 pack/year on average), and alcohol consumers. The main symptoms that were reported included the following: hoarseness and odynophagia. All the patients were submitted to radiotherapy; some of them had more than one treatment, such as surgery and/or chemotherapy.
Conclusion: The results found confirm with the literature where the squamous cell carcinoma is the most common, majority of patients affected are men, and the risk factors are smoking and alcohol consumption. It is important to know the best approach for epidemiological profile of patients with this pathology.
