Résumé

To evaluate the role of oxaliplatin in neoadjuvant chemotherapy delivered after short-course irradiation. Using oxaliplatin in the above setting is uncertain. A subgroup of 136 patients managed by short-course radiotherapy and 3 cycles of consolidation chemotherapy within the framework of a randomised study was included in this post-hoc analysis. Sixty-seven patients received FOLFOX4 (oxaliplatin group) while oxaliplatin was omitted in the second period of accrual in 69 patients because of protocol amendment (fluorouracil-only group). Grade 3+ acute toxicity from neoadjuvant treatment was observed in 30% of patients in the oxaliplatin group vs. 16% in the fluorouracil-only group ( Our findings do not support adding oxaliplatin to three cycles of chemotherapy delivered after short-course irradiation.
