目前,T3N0直肠癌的新辅助放化疗的应用仍存在争议。此研究的目的在于应用临床表现、核磁共振以及病理参数来确定可免除新辅助放化疗的局部复发风险低的直肠癌患者。研究人员主要以3年及5年局部复发率作为衡量标准,回顾性分析了经过根治术的连续直肠癌患者的病例数据资料,包括166例病理学检查证实的肿瘤距肛门5~12 cm,术前环周切缘>1 mm的T3N0直肠癌患者。结果表明:随访期间有5患者出现肿瘤局部复发,总的3年及5年复发率分别为2.5%和3.4%。清扫的 Currently, the use of neoadjuvant chemoradiation in T3N0 rectal cancer remains controversial. The aim of this study was to identify clinical and nuclear magnetic resonance (MR) and pathological parameters in patients with rectal cancer who are at a lower risk for local recurrence of neoadjuvant chemoradiation. The researchers mainly used the 3-year and 5-year local recurrence rates as a measure to retrospectively analyze the case data of patients undergoing radical resection of colorectal cancer including 166 pathologically confirmed tumors ranging from 5 to 12 cm anus T3N0 rectal cancer patients with anterior margin> 1 mm. The results showed that there were 5 patients with local tumor recurrence during follow-up, the total 3-year and 5-year recurrence rates were 2.5% and 3.4% respectively. Sweeping
