OBJECTIVE: To evaluate the audiological profile of cancer patients. METHODS: Thirty-three patients who underwent chemotherapy and/or radiotherapy in the oncology sector of the Hospital de Urgências de Sergipe were included. An anamnesis was taken and meatoscopy and tonal and vocal audiometry were performed. Outcomes: The majority of the patients were women (87.9%), and the average age of the patients was 48.4 years. The most common type of cancer was breast cancer (72.7%), followed by head and neck cancer (15.2%), and 87.9% of the patients underwent surgical treatment. After surgery, 69.7% and 63.6% of the patients underwent radiotherapy and chemotherapy, respectively, whereas only 9.1% underwent both radiotherapy and chemotherapy. At the time of the audiological evaluation, 48.5% were undergoing chemotherapy and/or radiotherapy courses and 48.5% had completed treatment. Approximately half of the patients (57.6%) reported good hearing, but only 27.3% underwent audiometry. Tinnitus was found in 69.7% of the patients and hearing complaints became worse after chemotherapy in 36.4% of the patients. Audiometry revealed sensorineural hearing loss in 28.8%, mixed hearing loss in 3.0%, and a normal hearing threshold in 68.2%. CONCLUSION: Patients who underwent chemotherapy expressed hearing complaints and audiological changes. It is possible to monitor hearing features with an audiological evaluation in order to provide quality of life improvement.
