Summary for Physicians:

The distinction between extensive-stage small cell lung cancer (ES-SCLC) and limited-stage SCLC (LS-SCLC) is critical in understanding differences in disease burden and prognosis.

• ES-SCLC involves disease that has spread beyond a single hemithorax and is not suitable for inclusion within a single, tolerable radiation field. It often includes distant metastases, such as to the liver, brain, or bones. This stage is associated with a higher tumor burden and a poorer prognosis, with median overall survival typically of approximately 8-13 months, even with systemic therapy.
• LS-SCLC is confined to one hemithorax and regional lymph nodes and can be encompassed within a single radiation field. It generally presents with a lower tumor burden and has a relatively better prognosis, with median survival ranging from 15-20 months. A subset of patients may achieve long-term survival with curative-intent chemoradiation.

Understanding this distinction is essential for accurate staging, therapeutic decision-making, and setting realistic expectations for outcomes.
