The aim of this study is to report the epidemiologic characteristics of tumors of the cerebellopontine angle (CPAT) and internal acoustic meatus in adult Polish population throughout the second decade of XXI century and to analyze their treatment.
A retrospective analysis of patients with cerebellopontine angle (CPA) and internal acoustic meatus tumors diagnosed in Poland in 2011-2020 was performed. Data recorded in the National Health Fund (NHF) database were analyzed. International Classification of Diseases codes (ICD-9 and ICD-10) were used to identify study group patients and treatment procedures.
From 2011 to 2020 6,173 Polish adult patients were diagnosed with cerebellopontine angle and internal acoustic meatus tumors. The average incidence in Poland is 1.99 per 100,000 residents/year. It mostly affects women (61.64%), and the average age of patients is 53.78 years. The incidence has steadily increased over the past decade. Treatment has changed significantly over the years, with a definite increase in the number of patients treated with radiotherapy (from 0.54 to 19.34%), and a decrease in surgical therapies (from 41.67 to 6.8%). The most common symptoms were vertigo and/or dizziness (43.48%) and sensorineural hearing loss (39.58%). 4.65% of patients suffered from sudden deafness, in this group of patients the risk of CPAT detection was the highest (6.25 / 1000 patients).
The total incidence of CPAT and demographic characteristics of patients were comparable to other studies. Our study demonstrated the increased number of patients are being treated with radiotherapy and fewer with microsurgery. Sudden sensorineural hearing loss (SSNHL) is an uncommon manifestation of CPAT but proper diagnosis should be undertaken because the risk of diagnosis such tumors is greater in this group.
本研究旨在报告 21 世纪第二个十年期间波兰成年人桥小脑角（CPAT）和内听道肿瘤的流行病学特征，并分析其治疗方法。
对 2011 年至 2020 年在波兰诊断为 CPAT 和内听道肿瘤的患者进行回顾性分析。对国家卫生基金（NHF）数据库中的数据进行分析。使用国际疾病分类（ICD-9 和 ICD-10）代码识别研究组患者和治疗程序。
2011 年至 2020 年，6173 名波兰成年患者被诊断为 CPAT 和内听道肿瘤。波兰的平均发病率为每 10 万人 1.99 例。女性发病率（61.64%）高于男性，患者平均年龄为 53.78 岁。过去十年发病率呈稳步上升趋势。治疗方法在过去几年发生了显著变化，放射治疗患者数量明显增加（从 0.54 例增加到 19.34 例），手术治疗减少（从 41.67 例减少到 6.8%）。最常见的症状是眩晕和/或头晕（43.48%）和感音神经性听力损失（39.58%）。4.65%的患者患有突发性耳聋，在这组患者中，CPAT 检测的风险最高（6.25/1000 例）。
CPAT 的总发病率和患者的人口统计学特征与其他研究相似。我们的研究表明，越来越多的患者接受放射治疗，接受显微手术治疗的患者越来越少。突发性感音神经性听力损失（SSNHL）是 CPAT 的一种罕见表现，但应进行适当诊断，因为在这组患者中诊断此类肿瘤的风险更高。
