Title:
Efficacy and safety analysis of bevacizumab combined with capecitabine in the maintenance treatment of RAS-mutant metastatic colorectal cancer
Published date:
02/25/2022
Excerpt:
CONTRADICTING EVIDENCE: The median progression-free survival (mPFS)of patients was 9.0 months (95% CI 8.0-10.0) in the observation group and 7.2 months (95% CI 6.0-8.4) in the control group, with a statistically significant difference (p < 0.05)….Bevacizumab combined with capecitabine was well tolerated and contributed to a longer PFS time than capecitabine alone, and it is worthy of popularization in clinical practice.

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.
