Induction treatment with FOLFIRINOX or oxaliplatin-based doublet followed by long-course chemoradiotherapy and surgery in locally advanced rectal cancer. A systematic review and pooled analysis from phase II and III trials.

Induction with FOLFIRINOX showed better survival outcomes and pCR rates respect to CAPOX at the price of increased G3-4 neutropenia and nausea/vomiting. A randomized study comparing triplet and doublet chemotherapy in the frame of a total neoadjuvant treatment strategy is widely warranted.
