摘要
目的回顾性分析宁夏地区回、汉族三种上消化道肿瘤患者的流行特征,为更好地开展肿瘤防治工作提供参考依据.方法收集整理2003-01-01/2012-12-31十年间在宁夏医科大学总医院住院治疗的5616例回、汉族上消化道肿瘤(食管癌、贲门癌、胃癌)患者临床资料.以患者确诊日期作为观察起点,以因上消化道肿瘤死亡的日期作为观察终点,对上消化道肿瘤手术患者(3634例)进行电话随访,随访成功1454例患者,生存时间的计算截止到2016-01-26.建立数据库,采用描述性统计方法分析患者年龄、性别、民族、入院时间、结局变量、生存时间等指标的分布特征,用寿命表法分时期和民族求出1年、3年和5年的生存率.用KaplanM e i e r法计算中位生存时间,生存率比较用Log-rank检验.结果共有5616例患者资料纳入分析,其中汉族患者4695例(83.5%),回族921例(16.5%),汉族vs回族比例为5.10 vs 1;男性患者共计4325例(77.0%),女性患者1291例(23.0%),男性vs女性比例为3.35 vs 1;食管癌患者1563例(27.8%),贲门癌患者1478例(26.3%),胃癌患者2575例(45.9%);食管癌与贲门癌均以≥60岁组(67.7%vs 63.9%)患者为主,胃癌以40-60岁组(45.9%)及≥60岁组(45.1%)患者为主.上消化道肿瘤手术患者3634例,其中食管癌手术患者794例,回、汉族中位生存时间分别为29 mo vs 38 mo,回、汉族1、3、5年生存率分别为72.3%vs 74.7%、46.8%vs50.9%、23.4%v s 30.9%.贲门癌手术患者734例,回、汉族中位生存时间分别为62 mo vs 33 mo,回、汉族1、3、5年生存率分别为73.9%vs 76.3%、58.7%vs 48.0%、54.3%vs39.9%.胃癌手术患者2106例,回、汉族中位生存时间分别为98 mo vs 81 mo,回、汉族1、3、5年生存率分别为77.3%vs 77.0%、50.7%vs 48.1%、24.7%vs 22.7%,食管癌、贲门癌、胃癌患者回、汉族间1、3、5年生存率差异均无统计学意义(P>0.05).结论宁夏地区三种上消化道肿瘤患者在性别与年龄的分布与我国其他区域相同病种患者的分布近似;宁夏地区胃癌与贲门癌患者数量呈现逐年递增趋势;包括宁夏在内的几个北方地区的胃癌人群5年生存率低于南方地区人群.
AIM To retrospectively analyze the epidemiological characteristics and survival of Chinese Hui and Han patients with three types of upper gastrointestinal cancer in Ningxia.METHODS A total of 5616 hospitalized Hui and Han patients with upper gastrointestinal cancer(esophageal cancer, cardia cancer or gastric cancer) treated at the General Hospital of Ningxia Medical University from January 1, 2003 to December 31, 2012 were included in this study. The date of diagnosis was set as a starting point for observation and the date of death due to upper gastrointestinal cancer was set as the end of the observation, with a calculated survival time as of January 26, 2016. All patients who underwent surgery for upper gastrointestinal cancer(3634 cases) were followed by telephone, and a final successful follow-up was achieved in 1454 patients. A database was created to analyze the clinical characteristics including patients' age, sex, ethnicity, hospitalization time, out come variables, and survival time by descriptive statistical method. The 1-, 3-, and 5-year survival rates were calculated using the lifetable method. The median survival time was calculated by Kaplan-Meier method. Survival rates were compared using the Log-rank test.RESULTS Of the 5616 hospitalized patients included, 4695(83.5%) were Han Chinese, and 921(16.5%) were Hui Chinese. The ratio of Han to Hui patients was 5.10:1. There were 4325 male patients(77.0%) and 1291 female patients(23.0%). The ratio of male to female patients was 3.35:1. There were 1563(27.8%) cases of esophageal cancer, 1478(26.3%) cases of cardia cancer, and 2575(45.9%) cases of gastric cancer. Esophageal cancer and cardiac cancer were mainly seen in patients aged ≥ 60 years(67.7% and 63.9%, respectively). Gastric cancer was mainly seed in patients aged 40-60 years(45.9%) and ≥ 60 years(45.1%). Of 3634 patients who underwent surgery for upper gastrointestinal cancer, 794 had esophageal cancer, in which the median survival time of Hui and Han patients was 29 mo vs 38 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 72.3% vs 74.7%, 46.8% vs 50.9%, and 23.4% vs 30.9%, respectively; 734 had cardia cancer, in which the mediansurvival time of Hui and Han patients was 62 mo vs 33 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 73.9% vs 76.3%, 58.7% vs 48.0%, and 54.3% vs 39.9%, respectively; 2106 had gastric cancer, in which the median survival time of Hui and Han patients was 98 mo vs 81 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 77.3% vs 77.0%, 50.7% vs 48.1%, and 24.7% vs 22.7%, respectively. There was no signifi cant difference in the 1, 3, 5-year survival rates between Hui and Han patients with esophageal cancer, cardia cancer or gastric cancer(P > 0.05).CONCLUSION The distribution of sex and age in patients with the three types of upper gastrointestinal cancer in Ningxia is similar to that in other regions of China. The number of patients with gastric cancer and cardia cancer had an increasing trend during the past years. The 5-year survival rate of patients with gastric cancer in the northern regions including Ningxia is lower than that of the southern population.
