In the last years, a dramatic increase in colorectal cancer (CRC) diagnoses in early-onset (EO) patients has been observed. The prognosis of EO-CRC compared to late-onset (LO) patients is still unclear. This meta-analysis aims to clarify whether there is any difference in the prognosis between the two groups.
A systematic review was conducted on EMBASE-Medline, Pubmed and Cochrane Library in March 2024 to identify studies comparing overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), local recurrence (LR) and distant recurrence (DR) risk outcomes between EO-CRC (<50 years old) and LO-CRC (>50 years old) with at least 50 patients per group and one year of follow-up. The risk of bias was assessed with the ROBINS-E tool. Data from stage prevalence and survival were extracted and meta-analysed. Meta-regression was used to identify impacting effect modifiers. The PROSPERO registration number was CRD42024573264.
Twenty-six studies were identified; 1,062,037 patients (13.4% EO-CRC and 86.6% LO-CRC) were included in the stage prevalence and 567,689 in the prognostic meta-analysis. Overall, 60% of the EO-CRC and 49% of the LO-CRC were diagnosed with an advanced stage (III-IV) of disease (RR 1.26, 95%CI 1.19-1.35, I=87%). EO-CRC had a better OS than LO-CRC (HR 0.89, 95%CI 0.81-0.99, I=89%) but equal CSS (HR 0.94, 95%CI 0.83-1.06, I=82%), DFS (HR 1.05 95%CI 0.94-1.16, I=76%), LR (HR 1.41, 95%CI 0.62-3.18, I=49%) and DR (HR 1.51, 95%CI 0.79-2.89) risk. Meta-regression analysis identified a worse DFS in the EO-CRC rectal cancer subgroup (HR 1.14, 95%CI 1.00-1.30, I=0%).
Despite the high heterogeneity of existing studies, EO-CRC patients are diagnosed with significantly more advanced stages than LO-CRC, although this is not reflected in any difference in cancer-related survival. There is an urgent need for increased vigilance in the early detection of CRC in young patients.
在过去几年中,早发性(EO)结直肠癌患者的诊断数量急剧增加。与晚发性(LO)患者相比,EO-CRC的预后仍不清楚。本荟萃分析旨在阐明两组之间的预后是否存在差异。
2024年3月对EMBASE-Medline、Pubmed和Cochrane图书馆进行了系统评价,以确定比较EO-CRC(<50岁)和LO-CRC(>50岁)之间总生存期(OS)、癌症特异性生存期(CSS)、无病生存期(DFS)、局部复发(LR)和远处复发(DR)风险结果的研究,每组至少50例患者,随访1年。使用ROBINS-E工具评估偏倚风险。提取并对来自阶段患病率和生存期的数据进行荟萃分析。使用荟萃回归来确定影响效应修饰因素。PROSPERO注册号为CRD42024573264。
共纳入26项研究;1,062,037例患者(13.4%为EO-CRC,86.6%为LO-CRC)纳入阶段患病率分析,567,689例纳入预后荟萃分析。总体而言,60%的EO-CRC和49%的LO-CRC被诊断为疾病晚期(III-IV期)(RR 1.26,95%CI 1.19-1.35,I=87%)。EO-CRC的OS优于LO-CRC(HR 0.89,95%CI 0.81-0.99,I=89%),但CSS(HR 0.94,95%CI 0.83-1.06,I=82%)、DFS(HR 1.05,95%CI 0.94-1.16,I=76%)、LR(HR 1.41,95%CI 0.62-3.18,I=49%)和DR(HR 1.51,95%CI 0.79-2.89)风险相当。荟萃回归分析发现EO-CRC直肠癌亚组的DFS较差(HR 1.14,95%CI 1.00-1.30,I=0%)。
尽管现有研究存在高度异质性,但EO-CRC患者被诊断为晚期的比例明显高于LO-CRC,尽管这在癌症相关生存期方面没有任何差异。迫切需要提高对年轻患者CRC早期检测的警惕性。
