Advancements in Targeted Therapy for EGFR Positive Lung Cancer – A Comprehensive Overview

Overview of EGFR Positive Lung Cancer

EGFR (Epidermal Growth Factor Receptor) positive lung cancer is a specific type of lung cancer where cancer cells have a mutation in the EGFR gene. This mutation makes the cancer cells more dependent on the EGFR pathway for their growth and survival.

Key Points:

  • EGFR positive lung cancer accounts for approximately 10-15% of non-small cell lung cancer cases.
  • The mutation is more common in non-smokers and in individuals of Asian descent.
  • Patients with EGFR positive lung cancer tend to be younger and have a better prognosis compared to those with EGFR negative lung cancer.
  • Testing for EGFR mutations is essential for the appropriate treatment selection.

Patients with EGFR positive lung cancer may experience symptoms such as persistent cough, chest pain, weight loss, and shortness of breath. It is crucial to consult a healthcare provider for proper diagnosis and treatment.
