摘要
目的研究主要恶性肿瘤死亡率的地域分布有无规律性,为下一步寻找病因,为政府制定干预措施提供理论依据。方法利用山东省某县主要恶性肿瘤死亡率资料,进行地域趋势面分析。结果胃癌和鼻咽癌死亡率的分布有明显的地域规律性。其中,胃癌死亡率在该县呈由西向东逐渐增高,鼻咽癌则呈现由西向东逐渐降低的趋势。另外,有些地区的剩余值明显高于(或低于)剩余界值,呈现出规律外的特殊性。结论胃癌、鼻咽癌死亡率在山东省某县内有地域差异,应进一步研究具体生活习惯、经济状况等因素的差异及与相关肿瘤的关系,对于存在异常剩余值的地区,应作为重点研究对象,探讨这些地区可能存在的某种肿瘤保护或危险因素。
Objective To study the regularity in geographical distribution of the malignant tumor mortality. Methods Utilizing the tumor mortality data of different regions of some county in Shandong province, the trend-surface analysis, a statistical methed of fitting curved surface based on multivariate regression analysis, was performed. Results The mortality of gastric cancer and nasopharyngeal carcinoma had geographical distribution trends. Gastric cancer mortality escalated gradually from west to east, and nasopharyngeal carcinoma mortality decreased from west to east. In addition, the residual value in some areas exceeded the limited residual value, which indicated that some particular affecting factors maybe exist in those areas. Conclusion The mortality of stomach and nasopha ryngeal carcinoma varied geographically in some county of Shandong province Research should be performed on the difference of the living habit, the economic situation in different areas, and the retationship between these factors and the relative tumor mortality. Attention should also be paid to the areas whose residual values are anomalous to study the particular protecting or hazardous factors.
