構(gòu)建轉(zhuǎn)移性胃癌患者的生存預(yù)測(cè)模型 ——基于SEER數(shù)據(jù)庫(kù)的回顧性研究
發(fā)布時(shí)間:2021-07-01 12:51
背景及目的:胃癌是最常見(jiàn)的惡性腫瘤之一,也是全世界范圍內(nèi)腫瘤死亡的主要原因之一。由于其早期癥狀隱匿且缺乏早期篩查,許多胃癌患者發(fā)現(xiàn)時(shí)已是晚期,甚至出現(xiàn)遠(yuǎn)處轉(zhuǎn)移。迄今為止,針對(duì)遠(yuǎn)處轉(zhuǎn)移性胃癌還未制定行之有效的診療指南和臨床研究,臨床醫(yī)師在制定相關(guān)治療策略時(shí)往往是基于以往經(jīng)驗(yàn),缺少科學(xué)依據(jù)。本研究回顧性分析遠(yuǎn)處轉(zhuǎn)移性胃癌患者的臨床病理特征,建立患者生存預(yù)后模型,旨在為臨床醫(yī)師制定個(gè)性化治療方案時(shí)提供參考依據(jù)。方法:本研究利用美國(guó)國(guó)立研究所監(jiān)測(cè)、流行病學(xué)和最終結(jié)果(The Surveillance,Epidemiology,and End Results,SEER)數(shù)據(jù)庫(kù),回顧性分析2010-2016年由組織學(xué)確診的遠(yuǎn)處轉(zhuǎn)移性胃癌(metastatic gastric cancer,mGC)患者的人口學(xué)及臨床病理特征和生存信息,按照納入和排除標(biāo)準(zhǔn)共得到3742例符合條件的患者。本研究分別建立預(yù)測(cè)mGC患者的總體生存期(overall survival,OS)和胃癌特異性死亡期(gastric cancer specific survival,CSS)的預(yù)測(cè)模型,然后利用列線圖將各預(yù)測(cè)模型進(jìn)行...
