目的：了解新疆地区肺部原发性肿瘤发病情况及其民族分布。方法：对９７３ 例肺部原发性肿瘤分别按民族、病变组织学类型、性别、年龄进行了统计分析。结果：９７３ 例中，恶性肿瘤（９７．２２％ ）明显多于良性肿瘤（２．７８％ ），肺癌占恶性肿瘤的９９．４７％ ；不同民族肺部原发性肿瘤就诊率之间有差异，汉族的较高而维吾尔族的较低；９４６ 例恶性肿瘤中肺鳞癌所占的比例最高；各民族病例在不同组织学类型之间的分布无显著性差异（Ｐ＞ ０．０５）；恶性肿瘤男女比例为５．８∶１。结论：肺部原发性肿瘤在新疆地区发病情况及其民族分布有所特殊，在肺部原发性肿瘤，尤其是肺癌发病中有无不同遗传基因因素和致癌因素待进一步研究
Objective: To understand the incidence and ethnic distribution of primary tumors in the lungs in Xinjiang. Methods: A total of 973 lung primary tumors were statistically analyzed according to nationality, histological type, gender, and age. Results: Of the 973 cases, malignant tumors (97.22%) were significantly more than benign tumors (2.78%), and lung cancer accounted for 99.47% of malignant tumors; there was a difference between visit rates of primary tumors of different national lungs. The proportion of Han nationality is higher and that of Uygur is lower; among 946 cases of malignant tumors, the proportion of lung squamous cell carcinoma is the highest; there is no significant difference in the distribution of different histological types among ethnic groups (P> 0.05); The male to female ratio of malignant tumors was 5.8:1. Conclusion: The incidence and ethnic distribution of lung primary tumors in Xinjiang region are special. Whether there are different genetic factors and carcinogenic factors in the primary lung tumors, especially the incidence of lung cancer, need further study.
