单中心肩胛骨肿瘤166例流行病学分析

An one-center epidemiological analysis of scapular tumors:166 cases report

目的分析肩胛骨肿瘤的流行病学特征及影像学特点,提高对肩胛骨肿瘤的认知及疾病诊断水平。方法回顾1980年至2014年,北京积水潭医院骨肿瘤科收治的资料完整的166例肩胛骨肿瘤病例。总结分析患者的性别、年龄、病理类型、肿瘤部位及影像学特点。结果原发肿瘤133例,转移瘤33例。男111例,女55例,男女比例2.02∶1,年龄5-80岁。原发恶性肿瘤74例,占44.58%;转移瘤33例,占19.88%;中间型肿瘤18例,占10.84%;良性肿瘤41例,占24.70%。原发恶性肿瘤中位发病年龄为31（6-80）岁,常见肿瘤有软骨肉瘤、Ewing肉瘤、骨肉瘤;转移瘤中位发病年龄为54（36-79）岁,常见原发部位为肺癌、乳腺癌、前列腺癌;中间型肿瘤中位发病年龄为18（5-62）岁,常见病种有软骨母细胞瘤、朗格汉斯细胞组织细胞增生症、骨巨细胞瘤;良性肿瘤中位发病年龄25（10-62）岁,常见病种有骨软骨瘤、内生软骨瘤、单纯性骨囊肿。结论肩胛骨肿瘤中,恶性占大多数,转移瘤、软骨肉瘤、Ewing肉瘤、骨肉瘤较常见,良性肿瘤中以骨软骨瘤最多。

Objective To deepen the understanding of scapular tumors and to improve the diagnosis by analyzing the epidemiological and radiological features of scapular tumors.Methods Data of our tumor database were reviewed.There were 166 cases of scapular tumors whose demographic data,medical images and pathological data were intact between 1980 and 2014.The pathological types,age and gender of patients,and lesion location were recorded.The radiological data were examined by 2 veteran bone tumor specialists to determine the anatomic sites and radiological features of tumors.Based on the data stated above,epidemiological features of all kinds of scapular tumors were analyzed,with statistical analysis of gender,age,tumor types,locations and radiological features.Results There were 133 cases of primary tumors and 33 cases metastatic tumors.One hundred and eleven cases of them were male patients and 55 were female,and the ratio of males to females was 2.02 ：1.Age of onset varied from 5 to 80 years.There were 74 cases（ 44.58%） of primary malignancy,33 cases（ 19.88%） of metastatic malignancy,18 cases（ 10.84%） of intermediate tumors and 41 cases（ 24.70%） of benign tumors.The median age of primary malignancy was 31 years old（ range：6-80 years）.The most common tumor types were chondrosarcoma,Ewing＇s sarcoma and osteosarcoma.The median age of metastatic malignancy was 54 years（ range：36-79 years）.The most common primary tumor types were lung cancer,breast cancer and prostate cancer.The median age of intermediate tumors was 18 years（ range：5-62 years）.The most common tumor types were chondroblastoma,Langerhans cell histiocytosis and giant cell tumors.The median age of benign tumors was 25 years（ range：10-62 years）.The most common tumor types were osteochondroma,enchondroma and simple bone cyst.Conclusions Malignant tumors are more common than the benign ones among scapular tumors.Metastatic tumors,chondrosarcoma,Ewing＇s sarcoma and osteosarcoma are common malignant types,and osteochondroma is the most common benign tumors located in scapula.
