What this Trial Is About

The goal of this prospective phase II feasibility study is to evaluate two additional local treatment options in rectal cancer patients with a good clinical response after neoadjuvant (chemo)radiation: contact x-ray brachytherapy versus extension of the waiting interval with or without local excision, and to investigate which rate of organ preservation can be achieved.

Eligibility Criteria

Eligible

You may qualify if you...

  • Histologically confirmed adenocarcinoma located above the dentate line and within 10 cm of the anal verge

  • Radiation dose greater than 50.4 Gy or boost dose on the primary tumor
  • Presence of suspicious lymph nodes (yN1/N2) at first response evaluation
  • Residual tumor 3 cm or larger or involving over half the circumference of the rectal lumen
