[目的]通过对1970年～1999年中山市鼻咽癌登记发病资料的动态分析 ,找出中山市鼻咽癌发病规律 ,为中山市开展肿瘤防治工作提供依据。[方法]收集中山市1970年～1999年间肿瘤登记的鼻咽癌新发患者资料 ,计算逐年的粗发病率及世界标化率 ,并对上述资料进行统计分析。[结果]1970年～1999年中山市鼻咽癌发病水平虽然存在一定的波动 ,但总的发病趋势呈明显上升 ,增长率为21 40% ,年平均增长速度为0 65%。[结论]1970年～1999年中山市鼻咽癌发病率总体水平呈上升趋势 ,这与以往报道的鼻咽癌发病率水平呈相对稳定不一致 ,是否提示80年代后期中山市鼻咽癌诊断水平的提高和(或)肿瘤登记质量的提高所致 ,还是环境因素改变所致 ,值得进一步研究。
[Objective] To analyze the dynamic data of registration of nasopharyngeal carcinoma in Zhongshan from 1970 to 1999 to find out the incidence of nasopharyngeal carcinoma in Zhongshan and provide evidence for the development of cancer prevention and control in Zhongshan City. [Methods] Data of newly diagnosed nasopharyngeal carcinoma patients registered in Zhongshan from 1970 to 1999 were collected to calculate the annual crude incidence rate and standardized rate in the world. The above data were statistically analyzed. [Results] Although there was some fluctuation in the incidence of nasopharyngeal carcinoma in Zhongshan from 1970 to 1999, the overall incidence trend showed a significant increase. The growth rate was 21 40%, and the average annual growth rate was 0 65%. [Conclusion] The overall incidence of nasopharyngeal carcinoma in Zhongshan City increased from 1970 to 1999. This was inconsistent with the previously reported incidence of nasopharyngeal cancer. It was suggested that the diagnosis level of nasopharyngeal carcinoma in Zhongshan in the late 1980s The increase in the quality of tumor registration and/or the increase in the quality of cancer registration, or the change in environmental factors, warrants further study.
