Personalising and Refining Neo-adjuvant Chemotherapy in Locally Advanced but Resecable Colon Cancer in the Elderly of 70 Years Old or More (FOxTROT2France)
Almost all of these patients undergo surgery, but many do not receive AC due to frailty (following surgery). This particularly affects patients over 70, who represent the majority of patients diagnosed with CC.
FOxTROT 2, a trial to test the role of NAC in older patients.

Biopsy-confirmed adenocarcinoma of the colon (or upper rectum if too high for radiotherapy), high-grade dysplasia is not acceptable ,
Patients with synchronous tumors are eligible, if the most advanced tumor meets the criteria above
Radiological stage T3/T4 and N0/N1/N2 and M0
