EPIDEMIOLOGICAL PROFILE AND EVOLUTION OF ANKLE MUSCULOSKELETAL TUMORS

ABSTRACT Objective: Characterizing ankle tumors, presenting the epidemiological profile of these lesions. Methods: Retrospective observational case series study to evaluate the results of clinical and/or surgical treatments of patients with ankle tumors whose first visit occurred from 1990 to 2020. The dependent variables were: benign bone tumor, malignant bone tumor, benign soft tissue tumor, malignant soft tissue tumor, and infection. The independent variables were: sex, age; presence of symptoms (pain/local volume increase/fracture), duration of symptoms until treatment, diagnosis, treatment, and recurrence. Results: In total, 70 patients were included-58.5% were women, with a mean age at the time of diagnosis of 21.66 years. Among all cases, 76% were bone tumor, 14% were soft tissue tumor, and 10% were infection. The mean age at the time of diagnosis was 21.7 ± 2.29 years. The overall prevalence of pain was 77.1%. In total, 55.6% patients had a general local volume increase 13.4% had fractures. The mean time from symptoms to treatment was 17.4 ± 4.61 months and the mean diagnosis time was 10.13 ± 0.86 months. Of all cases, 73.44% underwent surgical treatment and 22.64% had recurrence. Conclusion: In this series, ankle tumors corresponded mainly to bone tumors. Benign tumors were the most prevalent type of tumor and the highest occurrence was among young people. Level of Evidence IV, Case Series.

摘要 研究目的：明确踝关节肿瘤的特征，阐明此类病变的流行病学特征。方法：本研究为回顾性观察性病例系列研究，旨在评估1990年至2020年初次就诊的踝关节肿瘤患者的临床及/或外科治疗效果。本研究的因变量包括：良性骨肿瘤、恶性骨肿瘤、良性软组织肿瘤、恶性软组织肿瘤以及感染性病变；自变量包括：性别、年龄、症状表现（疼痛/局部肿胀/骨折）、症状出现至接受治疗的时长、诊断结果、治疗方案以及复发情况。结果：本研究共纳入70例患者，其中女性占比58.5%，确诊时的平均年龄为21.66岁。全部病例中，76%为骨肿瘤，14%为软组织肿瘤，10%为感染性病变。确诊时的平均年龄为21.7±2.29岁。整体疼痛患病率为77.1%。总计55.6%的患者存在局部肿胀，13.4%的患者出现骨折。症状出现至接受治疗的平均时长为17.4±4.61个月，平均诊断耗时为10.13±0.86个月。全部病例中，73.44%的患者接受了外科治疗，22.64%的患者出现复发。结论：本病例系列研究显示，踝关节肿瘤以骨肿瘤为主，良性肿瘤为最常见的肿瘤类型，且高发人群为青年群体。证据等级：IV级，病例系列研究。
