Study Notes
Patient Information
- 62-year-old male
- Retired factory worker
- 40 pack-year smoking history
- Family history of lung cancer (father died of lung cancer at age 70)
Presenting Symptoms
- Persistent cough (over 3 months)
- Weight loss (7 kg over 3 months)
- Chest pain
- Shortness of breath
- Hemoptysis (coughing up blood)
Diagnostic Findings
- Chest X-ray: Mass in the right upper lobe of the lung
- CT Scan: Confirmed 4.5 cm mass in the right lung with enlarged mediastinal lymph nodes (suggesting possible metastasis)
- Bronchoscopy with Biopsy: Confirmed Non-Small Cell Lung Cancer (NSCLC), specifically adenocarcinoma
- PET Scan: Increased uptake in the lung mass and mediastinal lymph nodes (indicating potential spread)
Staging
- Stage IIIA lung cancer (large tumor with spread to nearby lymph nodes but no distant metastasis)
Pathophysiology of Lung Cancer
- Uncontrolled growth of mutated cells in the lungs forming a mass or tumor
- Adenocarcinoma originates from glandular cells lining the alveoli
Risk Factors for Lung Cancer
- Smoking: Primary cause (85-90% of cases), damages lung cell lining
- Secondhand Smoke: Increases risk even in non-smokers
- Occupational Exposures: Industrial pollutants, asbestos, carcinogens
- Radon Exposure: Accumulates in homes, known risk factor
- Family History: Genetic predisposition can increase risk
Advances in Lung Cancer Treatment
- Targeted Therapies: Drugs targeting specific mutations (EGFR, ALK, ROS1) for improved outcomes
- Immunotherapy: Enhances immune system to fight cancer, PD-1 inhibitors (nivolumab, pembrolizumab) for improved survival
- Minimally Invasive Surgery: Video-Assisted Thoracoscopic Surgery (VATS) reduces invasiveness, recovery time, and complications
Conclusion
- Importance of early detection and comprehensive treatment for lung cancer managment
- Smoking cessation is crucial for prevention and treatment
- Advances in treatment, including targeted therapies and immunotherapy, offer hope for improved outcomes, especially for patients with specific genetic mutations
