2023 Annual Refresher Course - eContouring for Lung Cancer

This eContouring session will review best practices for lung cancer contouring, including the integration of 4DCT imaging and PET/CT. The cases covered will include a centrally located, early stage NSCLC and a locally advanced NSCLC. Participants will review generation of ITV from 4DCT data, best practices for CTV and PTV margins, and contouring of critical normal structures. They will also review how to incorporate findings from pathologic staging such as EBUS into treatment planning for locally advanced disease and best practices for nodal target volume delineation. The session will include 2 practice cases.

Target Audience

This program is designed to meet the interest of radiation oncologists and radiation oncology residents.

Learning Objectives

Upon completion of this activity, participants should be able to:

  • Accurately contour a centrally located, early stage NSCLC case planned for SBRT, including critical structures such as the proximal bronchial tree.
  • Accurately integrate radiographic and pathologic staging data to contour a locally advanced NSCLC case.
  • Integrate 4DCT data into their lung cancer contouring.
