Introduction: Risk Factors and Characteristics Defining SCLC

Key Takeaways

• SCLC is more aggressive than NSCLC, characterized by rapid growth and early metastasis, leading to poorer outcomes.
• Limited-stage SCLC is confined to one hemithorax, while extensive-stage involves distant metastasis, affecting prognosis significantly.
• Smoking is the primary risk factor for SCLC, with prevention strategies centered on smoking cessation and public health initiatives.
• Staging of SCLC relies on imaging and clinical evaluation, with potential future enhancements from advanced imaging and molecular diagnostics.
