284例朝鲜族儿童肿瘤临床病理特点分析

Statistic analysis of pathological biopsies from 284 cases of Korean child tumors

目的探讨朝鲜族儿童肿瘤的发病特点和规律，为少数民族儿童肿瘤的有效防治提供科学依据。方法对284例朝鲜族儿童肿瘤的病理资料进行统计分析。结果肿瘤的检出率随年龄增长逐渐增加，各年龄段之间差异有统计学意义（P〈0．05），好发年龄为7～14岁；良恶性之比9．52：1；某些肿瘤存在性别特点；良性肿瘤的分布具有较明显的年龄特点，以脉管性肿瘤（26．85％）、骨软骨肿瘤（23．23％）和表皮囊肿（11．68％）多见；恶性肿瘤以恶性淋巴瘤、软组织肉瘤和神经母细胞瘤（均占14．82％）较多见；在学龄期所占比例最大。结论朝鲜族儿童肿瘤的某些临床病理指标具有较明显的种族和群体特征。应当根据本地区小儿肿瘤的发病规律和特点，制定相应的防治措施。

Objective To explore the Clinical features and discipline of Korean child tumor, and provide a scientific basis for the effective prevention and treatment of minority children tumors. Methods A statistic study was based on 284 cases of child tumor which were confirmed by pathological examinations. Results Tumor detection rate gradually increased with age with a significant difference between ages （ P 〈 0. 05 ）, and tumor often appeared from 7 to 14 years old. The ratio of benign to malignant tumors was 9.52： 1. There were gender characteristics in certain tumors. There were obvious age characteristics in distribution of benign tumors. The vascular tumors （26. 85% ）, the chonodroid tumors （23.23%）, and epidermal cysts （11.68%） were more common in benign tumors. Malignant lymphoma, soft tissue sarcoma, and neuroblastoma cells tumor （ 14. 82% ） were more common in malignant tumors, and often appeared in school age. Conclusions Obvious racial and group identity existed in some tumor clinicopathological indi- cators of Korean children. Appropriate prevention and control strategies should be developed according to the local discipline and characteristics of child tumors.
