Study Population

patients with locally advanced rectal cancer who started neoadjuvant chemoradiotherapy and underwent radical surgery in West of China Hospital and completed the required MR examination before and after neoadjuvant treatment were included from March 2016 to December 2019.

You may qualify if:

  • pathological diagnosis of rectal cancer;
  • received neoadjuvant chemoradiotherapy before surgery;
  • before neoadjuvant therapy and before surgery, the patients received thin and high resolution MRI examination of the rectum.
  • before neoadjuvant therapy, colonoscopy, rectal contrast-enhanced ultrasound or MRI showed that the lower margin of the tumor was within 12cm from the anal margin;
  • pre-neoadjuvant clinical stage II/III (AJCC 7th edition);

You may not qualify if:

  • simultaneous distant metastatic tumor should be considered at the first diagnosis;
  • patients with distant metastasis were not considered at the initial diagnosis;
  • with other malignant tumors;
  • before neoadjuvant therapy, patients had received other relevant treatments;
  • to undergo palliative surgery or emergency surgery in the course of neoadjuvant therapy;
