- Description
- This was a retrospective clinical study of 97 metastatic colorectal cancer patients who received bevacizumab in conjunction with first-line chemotherapy (composed of 5-fluorouracil (5-FU) only, 5-FU + oxaliplatin, 5-FU + irinotecan, or 5-FU + oxaliplatin + irinotecan). It assessed the relationship between KRAS mutation status in primary tumors and response to bevacizumab-containing first line chemotherapy, as measured by PFS. Of the 97 patients, 58 had wildtype KRAS and 39 had mutations in KRAS—including G12A, G12C, G12D, G12R, G12S, G12V, and G13D. The study found that patients with KRAS-mutated tumors were not significantly more resistant to bevacizumab-containing first-line chemotherapy than patients with wildtype KRAS, as evidenced by a non-significant difference in PFS between the two groups (12.1 and 11.7 months, respectively).
