  Individualized care, we on a roll
  Molecular targets for lung cancer, you see
  Non-small cell type, that's the key
  
  Anaplastic lymphoma kinase, known as ALK
  Inhibitor's the game, it attacks
  For patients with NSCLC, ALK-positive
  It's effective, keeps 'em alive, no surprises
  
  But hold up, resistance starts to creep
  Inevitable, like counting sheep
  Real-time surveillance, that's the way
  Liquid biopsy, potential in play
  
  Circulating tumor cells, they roam
  Circulating DNA, free to roam
  Exosomes in body fluids, they show
  These markers detect resistance, here we go
  
  Sequencing and counting, the methods clear
  To catch resistance, make it disappear
  Guide the treatment, the follow-up plan
  Real-time insights, we take a stand
