EML4-ALK: Update on ALK Inhibitors.

Since the discovery of the first-generation ALK inhibitor, many other tyrosine kinase inhibitors have been demonstrated to be effective in the first line or further lines of treatment in patients with advanced non-small cell lung cancer with EMLA4-ALK translocation. This review traces the main milestones in the treatment of ALK-positive metastatic patients and the survival outcomes in the first-line and second-line settings with different ALK inhibitors. It presents the two options available for first-line treatment at the present time: sequencing different ALK inhibitors versus using the most potent inhibitor in front-line treatment.

Navigating Therapeutic Challenges in BRAF-Mutated NSCLC: Non-V600 Mutations, Immunotherapy, and Overcoming Resistance.

Although rare in non-small cell lung cancer (NSCLC), BRAF mutations present considerable therapeutic challenges. While the use of BRAF and MEK inhibitor combinations has significantly improved survival outcomes in patients with BRAF V600E mutations, no targeted therapies are currently available for class II and III mutations, leaving the optimal treatment strategy and prognosis for these patients uncertain. Additionally, despite immunotherapy typically showing limited benefit in patients with other activating genomic alterations, it appears to deliver comparable efficacy in BRAF-mutated NSCLC, emerging as a potentially viable treatment option, particularly in patients with a history of smoking.
