Neoadjuvant Chemoradiation With 5-FU(or Capecitabine) and Oxaliplatin Combined With Hyperthermia in Rectal Cancer

• Status: Recruiting
• Trial end date: 2023-06-01
• Target enrollment: 0
• Participant gender: All

Summary

This trial examines the feasibility, effectiveness and safety of a combination of radiotherapy (over a period of five weeks) and chemotherapy (with 5-FU or Capecitabine and Oxaliplatin) and 10 fractions of deep regional hyperthermia in patients with primary locally advanced or locally recurrent rectal cancer. Previous pelvic irradiation in case of a local recurrence is not excluded from the trial. The treatment protocol aims on a preoperatively improved tumor regression allowing less aggressive surgery in primary locally advanced rectal cancer and a higher rate of curative resections in heavily pretreated locally recurrent rectal cancers.

Primary endpoint of the trial is the feasibility rate of a multimodal regimen consisting of radiochemotherapy and hyperthermia. Secondary endpoints are local control, survival rates, and toxicity. It is planned to include a total number of 59 patients over a period of 2.5 years.

Criteria

Inclusion Criteria:
