KRAS codon 61, 146 and BRAF mutations predict resistance to cetuximab plus irinotecan in KRAS codon 12 and 13 wild-type metastatic colorectal cancer

KRAS Codon 12 and 13 Mutations in Gastric Cancer in the Northeast Iran

Background & objective: KRAS mutations are reported in many types of cancers including pancreas, lung, colon, breast, and gastric (GC). High frequency of KRAS mutation is observed in the pancreas, colon, and lung cancers; they commonly arise in codon 12 and 13 of exon 2. Due to the lack of information about the frequency of KRAS</...

Mutations of KRAS/NRAS/BRAF predict cetuximab resistance in metastatic colorectal cancer patients

Approximately 45% of metastatic colorectal cancer (mCRC) patients with wild-type KRAS exon 2 are resistant to cetuximab treatment. We set out to identify additional genetic markers that might predict the response to cetuximab treatment. Fifty-three wild-type KRAS exon 2 mCRC patients were treated with cetuximab/irinotecan-based chemotherapy as a first- or third-line therapy. The mutational stat...

mutation and KRAS codon 13 mutations predict poor survival in Chinese colorectal cancer patients

Colorectal cancer: cetuximab, KRAS, BRAF, PIK3CA mutations and beyond.

With a long-term disease-free survival rate of 35% after multimodal treatment of stages II and III colorectal cancer (CRC) and mean overall survival (OS) of approximately 20 months in the metastatic setting, progress in the management of CRC is faster and the prognosis is better than for other gastrointestinal tumors [1]. Over the last 10 years systemic-targeted therapy has led to hope for furt...
