Total Neoadjuvant Treatment Without Surgery For Locally Advanced Rectal Cancer: Prospective Clinical Trial To Assess Tumor Complete Response, Circulating Tumor Genetic And Epigenetic Biomarkers, And Stromal Transcriptome To Interpret Clinical Outcome

2017-003671-60

NO-CUT is a one-stage phase II trial seeking to establish whether an oxaliplatin-based chemotherapy preceding standard neo-adjuvant fluoropyrimidines-based chemo radiotherapy, can safely spare demolitive surgical intervention in patients with operable rectal cancer, without increasing the risk of distant relapse. The trial also has a translational component aimed at establishing whether selected genomic, epigenetic, and transcriptomic markers are predictive of tumor and patient outcome.

Patients who are anticoagulated for atrial fibrillation or other conditions may participate, provided they are on stable doses of anticoagulant therapy. * Patients receiving other anticancer or experimental therapy.
