Objective To explore the expression of TRIB2 in colon cancer and its relationship with prognosis and immune cell infiltration. Methods TIMER database was used to analyse the expression of TRIB2 in pan-cancer．RNA-seq data and clinical information of colon cancer patients were downloaded from TCGA and GSE17538 to assess the correlation between TRIB2 with clinicopathological features．Survival curves,univariate and multivariate COX regression analysis were performed to explore the correlation between TRIB2 and prognosis,and a nomogram was constructed．Gene enrichment analyses were performed for TRIB2．Correlations between TRIB2 expression and immune cell infiltration,immune checkpoints,tumor mutation burden（TMB）,and immunotherapy sensitivity were analyzed．Results TRIB2 was highly expressed in colon cancer tissues（P<0.05）．The highest level of TRIB2 mRNA expression was found in CMS1．TRIB2 was an independent prognostic factor for colon cancer patients（univariate Cox regression analysis：HR=1.397,95%CI：1.100-1.774,P=0.006;multivariate Cox regression analysis：HR=1.502,95%CI：1.158-1.947,P=0.002）．TRIB2 was closely associated with immune cell infiltration and positively correlated with the expression level of immune checkpoint molecules as well as TMB（r=0.39,P<0.001）．The expression of TRIB2 was correlated with the efficacy of immune checkpoint inhibitors．Conclusions TRIB2 is highly expressed in colon cancer and is closely associated with poor prognosis and the immune microenvironment of colon cancer patients．

通过筛查和早期发现,可以降低结直肠癌（CRC）的发病率,有效切除肿瘤病变可以降低CRC的病死率。虽然对CRC的危险因素、发病机制和前体病变的了解已经取得进展,但最近年轻人群CRC发病率升高,原因尚不清楚。在过去十年中,出现了多种侵入性、半侵入性和非侵入性筛查方式。目前对结肠镜检查质量的重视提高了筛查的有效性,人工智能等影像新技术在肿瘤检测中的作用正在迅速显现。而且,CRC有效干预措施,如保肛治疗新术式、靶向治疗及免疫治疗领域的新进展,被证明可以提高CRC患者的生存率。该文旨在总结目前国内外CRC筛查方式和指南的证据,并综述CRC治疗领域的进展。

The incidence of colorectal cancer（CRC）can be reduced through screening and early detection．Effective resection of tumor lesions reduces mortality from CRC．Although progress has been made in understanding the risk factors,pathogenesis and precursor lesions of CRC,the reasons for the recent increase in the incidence of CRC in young adults are largely unknown．A variety of invasive,semi-invasive and non-invasive screening modalities have emerged in the last decade．The current emphasis on the quality of colonoscopy has improved the effectiveness of screening,and the role of new imaging technologies such as artificial intelligence in tumor detection is rapidly emerging．Moreover,there are effective interventions for CRC,such as new surgical modalities for anal preservation therapy,and new advances in the field of targeted therapy and immunotherapy,which have been shown to improve the survival rate of CRC．The aim of this article is to summarize the current evidence on CRC screening modalities and guidelines both nationally and internationally,and to provide an overview of advances in the field of CRC treatment．
