Targeted therapy is a crucial advancement in treating non-small cell lung cancer (NSCLC), focusing on specific molecular targets.

What is Targeted Therapy?

Targeted therapy refers to drugs that specifically target the molecular changes in cancer cells. Unlike traditional chemotherapy, which affects all rapidly dividing cells, targeted therapy aims to inhibit the growth of cancer cells while sparing normal cells.

QA: The Role of Targeted Therapy in NSCLC

• Q1: How does targeted therapy work?
  • A1: Targeted therapies work by identifying and attacking specific genes or proteins that contribute to cancer growth and survival.
• Q2: What are common targeted therapies used in NSCLC?
  • A2: Common targeted therapies for NSCLC include EGFR inhibitors (e.g., Erlotinib, Gefitinib), ALK inhibitors (e.g., Crizotinib, Alectinib), and angiogenesis inhibitors (e.g., Bevacizumab).
• Q3: Who is a candidate for targeted therapy?
  • A3: Candidates often include patients with specific genetic mutations, such as EGFR mutations or ALK rearrangements, identifiable through biomarker testing.
• Q4: What are the benefits of targeted therapy?
  • A4: Benefits include improved survival rates, fewer side effects compared to chemotherapy, and tailored treatment approaches based on individual tumor genetics.
• Q5: What are the potential side effects of targeted therapy?
  • A5: Potential side effects can include skin rash, diarrhea, liver problems, and effects on heart function, but they are generally less severe than those from chemotherapy.

Targeted Therapy Mechanisms

• EGFR Inhibition: Alters pathways critical for cell proliferation.
• ALK Inhibition: Targets abnormal ALK proteins, effectively halting cancer growth.
• Angiogenesis Inhibition: Prevents the formation of new blood vessels required for tumor growth.
