Advanced Non-Small Cell Lung Cancer

HIGH SEVERITY

The most common type of lung cancer (85% of cases) diagnosed at stage III or IV when cure is generally not possible. Major subtypes: adenocarcinoma, squamous cell carcinoma, large cell carcinoma. Strongly associated with smoking but occurs in never-smokers.

3Genetic mutations
4Smoking
5Alcohol consumption
6Obesity
7Physical inactivity
8Environmental exposures
9Infections (HPV, HBV, HCV, H. pylori)

Diagnostic Methods

  • 1Biopsy
  • 2Imaging (CT, MRI, PET)
  • 3Tumor markers
  • 4Genetic testing
  • 5Endoscopy
  • 6Blood tests
  • 7Screening programs

Prognosis

Untreated metastatic NSCLC has median survival of 4-6 months. With platinum chemotherapy, survival extends to 8-12 months. Targeted therapies for driver mutations (EGFR, ALK, ROS1, BRAF) offer 18-36 months median survival. Immunotherapy (pembrolizumab, nivolumab) in PD-L1 high tumors offers 24-30+ months median survival. Combination chemo-immunotherapy in non-squamous NSCLC offers 22-24 months. Brain metastases common; prophylactic cranial irradiation debated.

Prevention

  • Smoking cessation
  • Sun protection
  • Healthy diet
  • Regular exercise
  • Vaccination (HPV, HBV)
  • Screening programs
  • Limit alcohol
  • Maintain healthy weight

Research Status

Immunotherapy (PD-1/PD-L1 inhibitors: pembrolizumab, nivolumab, atezolizumab) first-line for many. Targeted therapies for EGFR, ALK, ROS1, BRAF, MET, RET, KRAS G12C mutations. Liquid biopsy for resistance monitoring.
