数据库研究第十一部分:结直肠癌的随访

Database research partⅪ:follow-up of colorectal cancer

目的分析华西肠癌数据库(Database from Colorectal Cancer,DACCA)中结直肠癌患者的随访相关数据。方法对DACCA数据库中的信息进行筛选,选择总数据中手术日期及随访日期中任一项不为空者,并对随访相关数据进行分析,包括随访时长、生存结果、应对方式(医生随访行为的应对方式)、随访途径(是否选择门诊、微信、QQ、电话、短信、APP随访、病房)以及随访次数(门诊随访次数、电话随访次数、术后5年内每年随访次数)。结果本研究最终获得符合筛选条件的数据6437条。(1)已满5年随访期(2004–2015年)的数据占总数据的56.6%(3642/6437),随访时间为0~201个月、中位随访时间(四分位数)为67(26,97)个月。(2)生存结果中,"生存"的数据构成比最高,为79.7%(4611/5787);已满5年随访期(2004–2015年)的数据中"生存"的数据构成比最高,为75.0%(2550/3401),其中2008年满5年随访期的生存率最高,为91.4%(235/257)。(3)医生随访行为的应对方式中,医生能主动进行随访的数据构成比最高,为76.8%(2121/2762)。(4)随访途径中采用门诊方式进行随访的数据构成比最高,为90.6%(4236/4676)。(5)门诊随访次数中原手术团队进行的门诊随访数据构成比最高,为100%(4380/4380),具体次数为0~130次、中位数(四分位数)为5(2,10)次。电话随访次数的数据占比为86.9%(3808/4380),具体次数为0~68次、中位数(四分位数)为0(0,1)次。第1年随访次数最高,占比89.9%(3044/3386),具体次数为0~73次、中位数(四分位数)为5(3,9)次。结论通过对目前华西DACCA数据库中结直肠癌随访真实世界数据的展示,可为利用大数据决策预后提供一些参考依据。

Objective To analyze the follow-up data of colorectal cancer in the Database from Colorectal Cancer(DACCA).Methods The information in the Dacca database was screened,and the one whose operative date and follow-up date were not blank in the total data was selected.The follow-up data were analyzed,including length of follow-up,survival outcomes,coping styles(doctors’attitude and reaction for follow-up),follow-up path(whether to choose out-patient,Wechat,QQ tools,phone call,text message,mobile application,face-to-face),the number of follow-up(the number of out-patient follow-up,the number of telephone follow-up,and the number of follow-up within 5 years).Results A total of 6437 data items were analyzed for colorectal cancer adjuvant follow-up.(1)The follow-up period of five years(2004–2015)was 56.6%(3642/6437),and the follow-up time was 0–201,67(26,97)months.(2)The highest data composition ratio of survival outcomes was“Survival”(79.7%,4611/5787),and in the data with five-year follow-up period(2004–2015),the highest data composition ratio of survival outcomes was“Survival”(75.0%,2550/3401),and the survival rate of the five-year follow-up period in 2008 was the highest(91.4%,235/257).(3)The highest data composition ratio of the coping styles was the doctors’active follow-up(76.8%,2121/2762).(4)The highest data composition ratio of the follow-up path was out-patient service(90.6%,4236/4676).(5)The highest data composition ratio of the number of out-patient follow-up was conducted by the original surgical team(100%,4380/4380),the specific number was 0–130、5(2,10)times.The data composition ratio of telephone follow-up was 86.9%(3808/4380)and the specific number was 0–68、0(0,1)times.The highest frequency of follow-up was in the first year(89.9%,3044/3386)and the specific number was 0–73、5(3,9)times.Conclusion By expounding the characteristics of the colorectal cancer follow-up from colorectal cancer in DACCA,it provides some references for using big data to determine prognosis.
