Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with confirmed locally recurrent rectal cancer that is deemed resectable.

Probably not a fit

Patients with evidence of metastatic disease or those who have had recent chemotherapy or radiotherapy may not benefit from this study.

What this trial studies

This multicenter, open-label, phase III study aims to evaluate the effectiveness of induction chemotherapy followed by neoadjuvant chemoradiotherapy and surgery in patients with locally recurrent rectal cancer. Participants will be randomly assigned in a 1:1 ratio to either the experimental arm receiving induction chemotherapy or the control arm receiving standard neoadjuvant chemoradiotherapy and surgery. The study seeks to determine if the addition of induction chemotherapy improves surgical outcomes and resection margins. The trial will involve multiple locations and will assess patient responses through imaging and clinical evaluations.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and increase the chances of complete resection in patients with recurrent rectal cancer.

How similar studies have gone: Other studies have explored similar neoadjuvant approaches, showing promising results, but this specific combination is being tested for the first time in this context.

* Known homozygous DPD deficiency
* Any chemotherapy in the past 6 months.
* Any contraindication for the planned chemotherapy, as determined by the medical oncologist.
* Radiotherapy in the past 6 months for primary rectal cancer.
