► Lung cancer remains the leading cause of cancer-related death in the United States, with a 5-year survival rate of approximately 18%. This video provides a comprehensive breakdown of the disease, from primary risk factors to the latest advancements in personalized medicine.
🧬 Pathophysiology and Risk Factors:
While smoking accounts for 85–90% of cases, environmental factors like radon, asbestos, and secondhand smoke also play a role. We explore how carcinogens cause p-53 mutations in smokers, while non-smokers often present with targetable EGFR mutations.
🔬 Types of Lung Cancer:
We dive into the major classifications, starting with Non-Small Cell Lung Cancer (NSCLC), which includes adenocarcinoma and squamous cell carcinoma. We also cover the highly aggressive Small Cell Lung Cancer (SCLC), detailing its neuroendocrine origin and distinct histological appearance.
⚠️ Clinical Presentation and Syndromes:
Learn to identify critical clinical signs, including paraneoplastic syndromes like SIADH and Cushing syndrome, as well as local spread manifestations like Pancoast syndrome and SVC syndrome.
🏥 Diagnosis and Personalized Treatment:
Discover the essential role of CT imaging, biopsy, and molecular testing. We discuss how identifying driver mutations (EGFR, ALK) and PDL1 expression allows for targeted therapies and immunotherapy, fundamentally changing the management of advanced disease.
