Course Description
Lung adenocarcinoma represents a histologically diverse tumor with challenges in classification and grading that have staging and prognostic impact. With the concept of pre-invasive neoplasia has come new approaches to measurement of invasive size, and these methods have been incorporated into AJCC staging. Invasive size assessments vary by observer and therefore standardization through review and education are vital to increase reliability and properly prognosticate. A new system of grading lung adenocarcinoma has been proposed, and this new system incorporates pattern-based classification.

Target Audience
Practicing academic and community pathologists, and pathologists-in-training

Learning Objectives
Upon completion of this educational activity, learners will be able to
  • Review patterns of pre-invasive and invasive adenocarcinoma as part of the upcoming update in the WHO classification system
  • Learn about the proposed grading system and how it is impacted by the pattern-based classification approach
  • Recognize invasive patterns and learn how to handle ambiguous or complex patterns into an invasive size for T-staging
