NCT03179540

Brief Summary

This is a 5 year Phase II study to evaluate the safety of non-operative management (NOM) in patients with low rectal cancer (LRC) who achieve a complete clinical response (cCR) following chemoradiotherapy (CRT). The safety of NOM will be evaluated by assessing (i) rate of local re-growth and (ii) rate of macroscopically positive resection margin (R2) when surgery is required due to local re-growth. NOM will be considered safe or as effective as surgery to achieve local control if the rate of local re-growth is equal to or less than 30% and the rate of a macroscopically positive margin is 0%.

Outcome Measures

Primary Outcomes (2)

  • Rate of local re-growth

    The safety of non-operative management will be evaluated by assessing the rate of local re-growth in the study population. This approach will be considered safe if the local re-growth rate is equal to or less than 30%.

    2 years

  • Rate of macroscopically positive resection margin

    The safety of non-operative management will be evaluated by assessing the rate of macroscopically positive resection margin following surgery in the study population. This approach will be considered safe if the rate is 0%.

Study Arms (1)

non-operative management

EXPERIMENTAL

Patients with low rectal cancer who have achieved a complete clinical response following chemoradiotherapy will undergo active follow-up with regular clinical visits, physical exam, endoscopy and imaging assessments at regular intervals for 2 years to assess for tumour re-growth or spread to the liver and lungs

Procedure: Non-operative management

Interventions

Patients who are eligible and provide informed consent to participate in the trial will undergo non-operative management (i.e., active surveillance for 24 months) according to the schedule outlined in the study protocol.
