Title:
Chemotherapy (doublet or triplet) plus targeted therapy by RAS status as conversion therapy in colorectal cancer patients with initially unresectable liver-only metastases. The UNICANCER PRODIGE-14 randomised clinical trial
Published date:
01/06/2022
Excerpt:
PRODIGE 14 was an open-label, multicenter, randomised Phase 2 trial. CRC patients with initially defined unresectable liver-only metastases received either, 2-CTx (FOLFOX or FOLFIRI) or 3-CTx (FOLFIRINOX), plus bevacizumab/cetuximab by RAS status. We failed to increase from 50 to 70% the R0/R1 liver-resection rate with the use of 3-CTx combined with bevacizumab or cetuximab by RAS status in CRC patients with initially unresectable liver metastases.
