摘要

多种倡议旨在开发无症状个体早期癌症检测的循环肿瘤DNA(CTDNA)测试。少数描述无症状和有症状患者CTDNA测试的研究报告了无症状患者的CTDNA检测较低。在这里,我们探讨了无症状患者是否与有症状的患者不同,例如通过在两次独立招募的无症状结直肠癌(CRC)(CRC)(队列#1:n = 215,队列#2:n = 368)和症状CRC(症状CRC(COMANTOMANT CRC(COMANTOMANT CRC))中,在两种独立招募的被招募的无症状结直肠癌(CRC)的患者中进行了两种独立招募的患者,进行了两种独立招募的患者,进行了两种独立招募的患者,并进行了两种独立的招募患者,并进行了两种独立的同类,并进行了#1:N = 117,对于肿瘤阶段和大小,与有症状的患者相比,无症状患者的CTDNA检测的几率显着降低(OR:0.4,95%CI:0.2-0.8:0.2-0.8,队列#2:OR:0.7,95%CI:0.5-0.9)。此外,无症状患者的复发风险较低(队列#1:SHR:0.6,95%CI:0.3-1.2,队列#2:SHR:0.6,95%CI:0.4-1.0)。值得注意的是,与有症状的患者相比,ctDNA阴性的无症状患者的复发风险最低(队列#1:SHR:0.2,95%CI:0.1-0.6:0.1-0.6,同伴2:SHR:0.3,95%CI:0.2-0.6)。需要进行此类见解来指导基于CTDNA的早期检测计划,并应促使讨论有关降低治疗的降级和CTDNA阴性无症状CRC患者的随访。

Abstract

Multiple initiatives aim to develop circulating tumour DNA (ctDNA) tests for early cancer detection in asymptomatic individuals. The few studies describing ctDNA-testing in both asymptomatic and symptomatic patients report lower ctDNA detection in the asymptomatic patients. Here, we explore if asymptomatic patients differ from symptomatic patients e.g. by including a 'low-ctDNA-shedding' and 'less-aggressive' subgroup.ctDNA assessment was performed in two independent cohorts of consecutively recruited patients with asymptomatic colorectal cancer (CRC) (Cohort#1: n = 215, Cohort#2: n = 368) and symptomatic CRC (Cohort#1: n = 117, Cohort#2: n = 722).After adjusting for tumour stage and size, the odds of ctDNA detection was significantly lower in asymptomatic patients compared to symptomatic patients (Cohort#1: OR: 0.4, 95%CI: 0.2-0.8, Cohort#2: OR: 0.7, 95%CI: 0.5-0.9). Further, the recurrence risk was lower in asymptomatic patients (Cohort#1: sHR: 0.6, 95%CI: 0.3-1.2, Cohort#2: sHR: 0.6, 95%CI: 0.4-1.0). Notably, ctDNA-negative asymptomatic patients had the lowest recurrence risk compared to the symptomatic patients (Cohort#1: sHR: 0.2, 95%CI: 0.1-0.6, Cohort#2: sHR: 0.3, 95%CI: 0.2-0.6).Our study suggests that asymptomatic patients are enriched for a 'low-ctDNA-shedding-low-recurrence-risk' subgroup. Such insights are needed to guide ctDNA-based early-detection initiatives and should prompt discussions about de-escalation of therapy and follow-up for ctDNA-negative asymptomatic CRC patients.
