Abstract

Background/Objectives: This retrospective study evaluates the predictive role of magnetic resonance imaging (MRI) in complications and recurrence in rectal cancer patients undergoing surgery and neoadjuvant therapy, highlighting the impact of structured reporting templates on MRI quality. Compared to traditional free-text reports, structured radiology reports offer a point-by-point evaluation, improving clarity and completeness by thoroughly addressing all relevant findings. MRI is critical in rectal cancer staging, guiding treatment based on tumor characteristics like T stage, sphincter involvement, vascular invasion, and lymph node status. Methods: A retrospective analysis of MRI and reports from 67 rectal cancer patients at the time of diagnosis, who were subsequently treated with neoadjuvant radiochemotherapy and surgery, was conducted. MRI report features, including tumor location, morphology, T stage, sphincter infiltration, mesorectal fascia involvement, lymph nodes, and extramural vascular invasion, were evaluated against European Society of Gastrointestinal and Abdominal Radiology (ESGAR) recommendations. Multivariate and univariate analyses were performed to correlate MRI findings with postoperative outcomes such as complications, local recurrence, bleeding, and 30-day anastomotic leaks. Results: Sphincter involvement showed a strong association with increased complications (multivariate β = 0.410, univariate r = 0.270). Extramural vascular invasion was linked to higher rates of local recurrence (multivariate β = 0.199, univariate r = 0.127). Lymph node involvement correlated with an elevated risk of postoperative bleeding (multivariate β = 0.133, univariate r = 0.293). Additionally, advanced T staging predicted a higher incidence of 30-day anastomotic leaks (multivariate β = 0.210, univariate r = 0.261). These findings may provide clinically relevant insights to support personalized surgical planning and improve preoperative risk stratification. Conclusions: Detailed MRI reporting, aligned with structured templates, significantly guides surgical and therapeutic strategies in rectal cancer management. However, the retrospective nature of the study and the limited sample size may affect the generalizability of the results.

结构化MRI报告对直肠癌预后的预测效用。
背景/目的:本回顾性研究评估磁共振成像(MRI)对直肠癌手术及新辅助治疗患者并发症和复发的预测作用,强调结构化报告模板对MRI质量的影响。与传统的自由文本报告相比,结构化放射学报告提供逐点评估,通过彻底解决所有相关发现,提高了清晰度和完整性。MRI在直肠癌分期中至关重要,根据肿瘤特征如T分期、括约肌受累、血管侵犯、淋巴结状态等指导治疗。方法:回顾性分析67例直肠癌患者在诊断时的MRI和报告,这些患者随后接受了新辅助放化疗和手术治疗。MRI报告的特征,包括肿瘤位置、形态、T分期、括约肌浸润、直肠系膜筋膜受累、淋巴结和外血管侵犯,根据欧洲胃肠和腹部放射学会(ESGAR)的建议进行评估。进行多因素和单因素分析,将MRI结果与术后结果(如并发症、局部复发、出血和30天吻合口渗漏)联系起来。结果:括约肌受累与并发症增加密切相关(多因素β = 0.410,单因素r = 0.270)。外血管侵袭与较高的局部复发率相关(多变量β = 0.199,单变量r = 0.127)。淋巴结受累与术后出血风险升高相关(多因素β = 0.133,单因素r = 0.293)。此外,晚期T分期预测30天吻合口瘘发生率较高(多变量β = 0.210,单变量r = 0.261)。这些发现可能为支持个性化手术计划和改善术前风险分层提供临床相关的见解。结论:详细的MRI报告,与结构化模板相一致,对直肠癌治疗的手术和治疗策略有重要指导作用。然而,该研究的回顾性性质和有限的样本量可能会影响结果的普遍性。
