摘要
With the growing threat of malignancy to health,it is necessary to analyze cancer incidence and patient survival rates among the residents in Pudong New Area of Shanghai to formulate better cancer prevention strategies.A total of 43,613 cancer patients diagnosed between 2002 and 2006 were recruited from the Pudong New Area Cancer Registry.The incidence,observed survival rate,and relative survival rate of patients grouped by sex,age,geographic area,and TNM stage were calculated using the Kaplan-Meier,life table,and Ederer II methods,respectively.Between 2002 and 2006,cancer incidence in Pudong New Area was 349.99 per 100,000 person-years,and the 10 most frequently diseased sites were the lung,stomach,colon and rectum,liver,breast,esophagus,pancreas,brain and central nervous system,thyroid,and bladder.For patients with cancers of the colon and rectum,breast,thyroid,brain and central nervous system,and bladder,the 5-year relative survival rate was greater than 40%,whereas patients with cancers of the liver and pancreas had a 5-year relative survival rate of less than 10%.The 1-year to 5-year survival rates for patients grouped by sex,age,geographic area,and TNM stage differed significantly(all P<0.001).Our results indicate that cancer incidence and patient survival in Pudong New Area vary by tumor type,sex,age,geographic area,and TNM stage.
With the growing threat of malignancy to health, it is necessary to analyze cancer incidence and patient survival rates among the residents in Pudong New Area of Shanghai to formulate better cancer prevention strategies. A total of 43,613 cancer patients diagnosed between 2002 and 2006 were recruited from the Pudong New Area Cancer Registry. The incidence, observed survival rate, and relative survival rate of patients grouped by sex, age, geographic area, and TNM stage were calculated using the Kaplan-Meier, life table, and Ederer II methods, respectively. Between 2002 and 2006, cancer incidence in Pudong New Area was 349.99 per 100,000 person-years, and the 10 most frequently diseased sites were the lung, stomach, colon and rectum, liver, breast, esophagus, pancreas, brain and central nervous system, thyroid, and bladder. For patients with cancers of the colon and rectum, breast, thyroid, brain and central nervous system, and bladder, the 5-year relative survival rate was greater than 40%, whereas patients with cancers of the liver and pancreas had a 5-year relative survival rate of less than 10%. The 1-year to 5-year survival rates for patients grouped by sex, age, geographic area, and TNM stage differed significantly （all P 〈 0.001）. Our results indicate that cancer incidence and patient survival in Pudong New Area vary by tumor type, sex, age, geographic area, and TNM stage.
