However, its role as a prognostic marker of overall survival independent of anti-EGFR therapy remains less clear.2 This is especially true for rectal cancer where studies have shown conflicting results on the predictive value of KRAS mutation status on response to neoadjuvant chemoradiation therapy. ...
For example, in the last few years, we've observed that mutations in KRAS predict resistance to anti-EGFR therapeutics in colon cancer. Earlier this year, the US Food and Drug Administration approved the first ever KRAS inhibitor for use in patients, in this case non-small cell lung cancer...
Impact of KRAS Mutation Status on Outcomes in Metastatic Colon Cancer Patients without Anti-Epidermal Growth Factor Receptor Therapy Purpose;Activating mutation of the KRAS oncogene is an established negative predictor for anti-epidermal growth factor receptor (anti-EGFR) therapies in me...

27,28. EachKRASmutation allele subtype has unique biochemical and clinicopathological features, and the differences between the mutation subtypes and co-mutations in pancreatic cancer have not been well studied26,27,28,29. TheKRASG12Dmutation has an intrinsic wildtype and SOS1 guanine exchange...
Colorectal cancer (CRC) is among the most commonly diagnosed cancers affecting both genders in the world. It is characterized by genetic instability, which drives tumor formation via the activation of oncogenes, such as KRAS and B-RAF. Approximately 40%

Approximately 30% to 50% of colorectal tumors are known to have a mutated (abnormal) KRAS gene, indicating that up to 50% of patients with colorectal cancer (CRC) might respond to anti-epidermal growth factor receptor (EGFR) antibody therapy. However, 40
It remains uncertain, however, whether KRAS mutation predicts prognosis or clinical outcome of colon cancer patients independent of anti-EGFR therapy.Methods: We conducted a study of 508 cases identified among 1,264 patients with stage III colon cancer who enrolled in a randomized adjuvant ...
Kyung Chu, RN, NYU Langone Perlmutter Cancer Center, discusses treating patients with different subtypes of KRAS mutation. Typically, EGFR inhibitors are used in lung and colon cancer to treat patients with KRAS mutations. However, this therapy has mixed clinical outcomes for the patients, varying ...
