Abstract:
Oncogenic mutations in B-type Raf kinase (BRAF) occur in 7-10% of metastatic colorectal cancers (mCRC). Despite recent improvements in survival in the general population of patients with mCRC, patients with BRAF-mutant mCRC continue to have poor response to most systemic therapies, and prognosis remains poor. There is a substantial unmet need for novel therapeutic strategies to treat patients with BRAF-mutant mCRC. This review outlines the epidemiology, molecular pathogenesis, prognosis, and mechanisms of treatment resistance of BRAF-mutated CRC. Additionally, this review highlights novel therapeutic strategies aimed at enhancing response and improving outcomes.
Insights

- Molecular Biology
Background:
- BRAF mutations are found in 7-10% of metastatic colorectal cancers (mCRC).
- BRAF-mutant mCRC patients exhibit poor response to standard therapies and have a dismal prognosis.
- A significant unmet need exists for effective treatments for BRAF-mutant mCRC.
Purpose of the Study:
- To review the epidemiology, molecular pathology, prognosis, and treatment resistance mechanisms of BRAF-mutated CRC.
- To highlight emerging therapeutic strategies for BRAF-mutant CRC.
Main Methods:
- Literature review of epidemiological data.
- Analysis of molecular pathogenesis and resistance mechanisms.
- Synthesis of current and novel therapeutic approaches.
Main Results:
- BRAF mutations significantly impact CRC progression and treatment outcomes.
- Understanding resistance mechanisms is key to developing new therapies.
- Several novel therapeutic strategies show promise for improving patient response.
Conclusions:
- BRAF-mutant CRC presents unique challenges requiring targeted therapeutic strategies.
