摘要

背景与目的：我国胃癌的发病率和死亡率呈逐年上升趋势，以人群为基础的胃癌生存率资料反映了胃癌诊治效果，也可以为评价胃癌人群综合防治效果提供参考。方法：根据上海市肿瘤登记处收集的2002—2006年胃癌登记和生存随访报告资料，采用寿命表法和EdererⅡ法计算胃癌患者的观察生存率(observed survival，OS)和相对生存率(relative survival，RS)。结果：上海市2002—2006年共诊断胃癌病例28 243例，患者5年OS和RS分别为32.15%和45.81%。35~54岁年龄段患者生存率高于其他年龄组；Ⅰ期患者的生存率明显高于其他分期患者；管状腺癌的胃癌患者生存率显著高于其他类型；郊区患者5年OS高于市区患者。不同性别患者的生存率差异无统计学意义。2002—2006年与1972—1976年相比，男、女性胃癌患者的生存率均显著上升。结论：不同年龄、居住区域、诊断时期别、肿瘤组织学类型和病理学类型的患者生存率差异有统计学意义。上海地区胃癌的5年OS和RS在过去30年中显著升高，但仍低于发达国家。应提高胃癌患者早期诊断率，以改善胃癌患者的生存及预后情况。

Abstract

Background and purpose: Incidence and mortality of gastric cancer have increased gradually in China. Population-based cancer survival rate can reflect improvements in cancer diagnosis and treatment

as well as provide evidence for gastric cancer prevention and control. Methods: Data from gastric cancer incidence and followup between 2002 and 2006 were collected by the Shanghai Cancer Registry. Life table and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS). Results: A total number of 28 243 gastric cancer cases were documented between 2002 and 2006 in Shanghai. The 5-year OS and RS of gastric cancer were 32.15% and 45.81%

respectively. Survival rates of gastric cancer varied by age

residence

diagnostic stage

and tumor histological type

but not by gender. Patients aged 35-44 years who were diagnosed at stage Ⅰ or with tubular adenocarcinoma

had the highest survival rates. Moreover

patients in rural areas had higher 5-year OS than those in urban areas. During the period 2002-2006

both 5-year OS and RS of gastric cancer increased dramatically

as compared with 1972-1976. Conclusion: Survival rates of gastric cancer varied by age

residence

diagnostic stage

and tumor histological type. The 5-year OS and RS significantly increased in Shanghai over the past three decades

but are still far below developed countries. Early diagnosis of gastric cancer would be an effective strategy to improve survival and prognosis of patients with gastric cancer.
