Dr. Rishi Agrawal discusses lung cancer staging in the context of the 8th edition of the TNM staging system by IASLC. Staging is crucial for categorizing disease extent, guiding treatment decisions, and estimating prognosis in lung cancer. Dr. Agrawal focuses on the T category (tumor size and location) within the staging system, emphasizing the importance of accurate measurement, using various views and reconstructions, and distinguishing between ground glass and solid components. He elaborates on T1 to T4 categories based on size and invasion criteria. The presentation also briefly touches on nodal and metastatic staging, highlighting the relevance of differentiating between surgical and nonsurgical candidates based on specific criteria. Dr. Agrawal concludes by discussing oligometastatic disease and the role of local ablative therapy for such cases.
