Title:

Mutations in DNA Repair Genes and Clinical Outcomes of Patients With Metastatic Colorectal Cancer Receiving Oxaliplatin or Irinotecan-containing Regimens

Excerpt:
DDR mutations occurred in 11 patients (22%). First-line treatment with an oxaliplatin-containing regimen was administered to 33 patients (31 FOLFOX, 2 XELOX), while 16 patients received FOLFIRI. Among DDR-mutated cases, first-line treatment with FOLFOX/XELOX correlated with a statistically significant improvement in median OS compared with FOLFIRI (3.4 vs.1.8 y; P=0.042) and numerically higher RR (50% vs. 33%; P=0.58)...Mutations in DDR genes were present in 22% of patients with mCRC. In patients with DDR-mutated tumors, initial treatment with FOLFOX/XELOX correlated with improved OS and a numerically higher RR compared with FOLFIRI.
