Clinical Trial Summary

This study proposal includes a prospective clinical trial of bone sparing treatment planning in anal cancer patients. We seek to lower the risk of bone damage, while adhering with the constrains to the bowel, bladder and other conventional Organs At Risk, and finally to describe the fraction of pelvic insufficiency fractures in patients treated with optimized radiotherapy.

Description:

Patients will receive standard (chemo)-radiotherapy according to national Danish Anal Cancer Group (DACG) guidelines, but the bone-sparing focus will be added to the algorithm for dose-constrains and planning objectives. A bone specific magnetic resonance scan will be performed at 1 year post treatment. Additional substudies include collection of blood samples for translational research purposes.
