摘要
本文基于福建省某医院对2003-2007年肿瘤患者的调查,按住院人数统计,对顺位前三类癌症患者的寿命分布模型进行了研究。研究发现:(1)40-50岁是女性子宫肿瘤发病的高峰期,并且有逐年增长的趋势;(2)剔除女性患子宫肿瘤人数的影响,肿瘤发病的高峰期转移到60-70岁这个年龄段,表现出其它肿瘤多发于老年人,而且肺癌、胃癌、肝癌患者人数尤为突出;(3)肺癌、胃癌、肝癌患者的寿命分布属同一分布族,并且均能通过随机截尾数据下的H-P检验。
Based on the survey of tumor patients in a hospital in Fujian Province from 2003 to 2007, this paper studied life distribution of cancer patients whose number is at top three. We find： Firstly, high-incidence period of uterine tumor is in 40 to 50 years old women, and incidence rate is increasing in recent years. Secondly, after removing the effect of uterine tumor, high- incidence period of the tumor is in 60 to 70 years old people and the number of patients suffering from lung cancer, gastric cancer, liver cancer are more than others. Lastly, the life distributions of lung cancer, gastric cancer and liver cancer belong to the same distribution family and the null hypothesis is not rejected by H-P test under random censored data.
