What to Expect as a Participant

This is an observational study. You will not receive an experimental treatment; researchers will collect data based on your existing condition or standard treatment.

This trial targets 50 participants in total. It began in 2023-05-19 with a primary completion date of 2026-09-18.

⚠ This information is for research awareness only. Always consult your physician before joining any clinical trial. Participation is voluntary and you may withdraw at any time.

Brief Summary

With 50 patients included, this trial would be the largest pilot study evaluating the value of MRI PET in locally advanced rectal cancer. On the other hand, it would be the only pilot study performing several MRI PET during neoadjuvant treatment. Presumably, the response assessed at the 2nd MRI PET (before cycle 4 or induction chemotherapy) would be predictive of the overall response at the end of neoadjuvant treatment. Then, it would be possible to predict precociously the tumor response.
