ALK

ALK, or Anaplastic Lymphoma Kinase, is a gene that encodes a protein involved in cell growth and development. Genetic alterations in ALK, such as rearrangements and fusions, are found in various cancers, including non-small cell lung cancer, anaplastic large cell lymphoma, and some pediatric neuroblastomas. These alterations lead to the production of abnormal ALK proteins that drive uncontrolled cell proliferation and tumour growth. Detecting ALK alterations is crucial for guiding treatment decisions, as ALK inhibitors are specifically designed to target and block the activity of these abnormal proteins. These targeted therapies have shown significant effectiveness in shrinking tumours and improving patient outcomes. Understanding ALK's role in cancer biology enables personalized treatment approaches, offering more precise and effective options for patients with ALK-positive cancers.
