Predicting Neoadjuvant Therapy Response of Rectal Cancer With MRI

June 19, 2023 updated by: Sun Ying-Shi
The purpose of this study is to investigate if MRI scans performed after neoadjuvant radiotherapy can predict the therapeutic response of rectal cancer following preoperative chemo-radiotherapy. This will help doctors to better tailor treatments for rectal cancer in the future.

Detailed Description

We proposed to constructed multi-parameter predictive model for predicting therapeutic response and pathological complete response(pCR) of patients with rectal cancer who received neoadjuvant chemoradiation. MR radiomics,convolutional neural networks, morphological parameters and quantitative functional parameters derived from diffusion-weighted MR images will be integrated for model construction.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Assessing response with MRI

Preoperative chemo-radiotherapy as standard treatment. Neoadjuvant therapy (long course intensity modulated radio-chemotherapy, GTV 50.6Gy, totally 22 fractions; Capecitabine 825mg/m2 /bid by oral administration).

Three MR examinations: first MRI taken within 1 week before preoperative chemo-radiotherapy; second MRI taken between 14-16days after the initiation of radio-chemotherapy; third MRI taken 7-9 weeks after the completion of preoperative chemo-radiotherapy.

All patients are scheduled to receive total mesorectal excision surgery 12-14 weeks after the completion of preoperative chemo-radiotherapy.

Three MR examinations: first MRI taken within 1 week before preoperative chemo-radiotherapy; second MRI taken between 14-16days after the initiation of radio-chemotherapy; third MRI taken 7-9 weeks after the completion of preoperative chemo-radiotherapy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Predictive value of eary MRI (14-16 days MRI) for assessing pathological complete response(pCR) at surgery
Time Frame: 2 years
A scoring system for predicting pCR will be developed based on MRI parameters and their changes between baseline and early MRI. No viable cancer cells seen in the resection specimen is regarded as pCR
2 years
Predictive value of preoperative MRI(7-9 weeks after the completion of preoperative chemo-radiotherapy) for assessing pCR
Time Frame: 2 years
A scoring system for predicting pCR will be developed based on MRI parameters
2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Predictive value of eary MRI (14-16 days after initiation of preoperative radio-chemotherapy) for assessing pathological response according to Tumour Regression Grade (TRG)
Time Frame: 2 years
A scoring system for predicting pathological response will be developed based on MRI parameters and their changes between baseline and early MRI.TRG1 is regarded as responder, and TRG2/3 is regarded as non-responder.
2 years
Feasibility of conducting MRI scans at 7-9 weeks after preoperative radio-chemotherapy
Time Frame: 2 years
This will be assessed in terms of whether MR imaging at 7-9 weeks after preoperative radio-chemotherapy adds any additional predictive value to imaging performed 14-16 days after initiation of preoperative radio-chemotherapy.
2 years
MRI-predicted pCR and MRI-predicted response on long-term disease control and survival
Time Frame: 3 years
3 years disease-free survival and overall survival will be assessed
3 years
Predictive value of preoperative MRI(7-9 weeks after the completion of preoperative chemo-radiotherapy) for assessing pathological response according to Tumour Regression Grade (TRG)
Time Frame: 2 years
A scoring system for predicting pathological response will be developed based on MRI parameters and their changes between baseline and early MRI.TRG1 is regarded as responder, and TRG2/3 is regarded as non-responder.
