Implementation of a Tumor Response Assessment Program Integrating the Shared Medical Decision Into the Organ Preservation Strategy for Rectal Cancer Patients
Sponsor: Centre Hospitalier Universitaire Dijon
Summary
The adoption of total mesorectal excision (TME) has standardized rectal cancer surgery and improved oncological outcomes. In locally advanced rectal cancer, neoadjuvant radio chemotherapy (NACRT) has further improved oncological benefit. Although these strategies result in good 5-year disease-free survival rates, they are associated with significant morbidity, in particular permanent long-term bowel, urinary and sexual dysfunction. In rectal cancer management, the main objective of organ preservation is to avoid or reduce morbidity and impact on quality of life after rectal resection, without compromising oncological outcomes. The aim of this project is to evaluate the efficacy of a defined response monitoring program, including a shared decision process, as a strategy for assessing tumor response in locally advanced rectal cancer after neoadjuvant therapy. This is a national, phase III, randomized, open-label, multicenter clinical trial comparing the tumor response monitoring program with shared decision-making, versus standard tumor response assessment in organ preservation strategies in rectal cancer.

Conditions
Interventions
Tumor response monitoring program
three steps of tumor response evaluation (STEP 1 at 2 months, STEP 2 at 4 months, STEP 3 at 6 months after completion of neoadjuvant treatment): STEP 1: digital rectal examination, pelvic MRI, rectoscopy, TAP scan STEP 2: DRE, pelvic MRI, rectoscopy STEP 3: DRE, pelvic MRI, rectoscopy, TAP or PET scan
Standard evaluation of tumor response
Assessment at 2 months (+/- 7 days) after neoadjuvant treatment: digital rectal exam, pelvic MRI, rectoscopy, TAP scan
Shared decision-making
At each stage of the monitoring program and depending on the clinical and oncological results, the decision to preserve the rectum will be discussed with the patient according to a shared-decision program.
Decision-making according to national recommendations
The decision to preserve the rectum is based on assessment at 2 months after completion of neoadjuvant treatment (standard of care since the GRECCAR2 trial).
Follow-up
Every 3 months for 2 years, then every 6 months for the third year
