MRI plays a pivotal role in the staging of early rectal cancer, resulting in allocation of patients to surgery or organ-sparing treatment. In this large population-based retrospective cohort study, MRI substantially understaged pT3 and overstaged pT1 rectal cancer, in addition to unreliable nodal staging. Based on these findings, MRI is not adequate in allocating patients with rectal cancer to organ-sparing treatment.
MRI 在早期直肠癌的分期中起着关键作用,可将患者分配至手术或保留器官的治疗。在这项大型基于人群的回顾性队列研究中,MRI 显著低估了 pT3 期直肠癌而高估了 pT1 期直肠癌,此外对淋巴结分期也不可靠。基于这些发现,MRI 不足以将直肠癌患者分配至保留器官的治疗。
