  • Patients with colorectal cancer and liver-only metastases showed improved outcomes when treated with FOLFOXIRI and bevacizumab compared to FOLFIRI and bevacizumab or with panitumumab, especially regarding progression-free survival and resection rates.
  • The CAIRO5 trial involved 530 patients with initially unresectable liver metastases from colorectal cancer, evaluated across numerous centers in the Netherlands and Belgium, focusing on different treatment combinations based on tumor genetics.
  • While more effective responses were observed with certain treatments, there was an increase in toxic side effects, particularly in specific genetic tumor variants like RAS/BRAFV600E.
