AM2019 ECON03 eContouring for Oligometastatic SBRT
This session will involve the collaboration of three radiation oncologists with expertise in spine and lung SBRT. We will review the anatomy of the lung and spine including adjacent critical structures. With regards to the spine, we will review details of target delineation for intact vertebral bodies and then apply these same concepts to target delineation for post-operative spine SBRT in our example case. For the lung, we will review the chest anatomy and contouring technique of a central/ultracentral lung tumor. Throughout the session, existing consensus contouring guidelines for spinal metastases will be reviewed. Relevant guidelines for early stage lung cancer lung SBRT will be reviewed with reference to lung oligometastases. The attendees will be provided with the cases as homework prior to the meeting. We will review contouring homework and discuss areas of consensus and controversy. Finally we will review our contours for the same cases and allow students to revise their contours with input from the presenters. Review of select audience contours in comparison to the expert contours will be performed for the purposes of teaching and discussion of acceptable vs. unacceptable deviations.
The meeting is designed to meet the interests of radiation oncologists, radiation dosimetrists, physicists, and residents.
- Identify the anatomic compartments of the spine and apply this knowledge to contour the CTV and PTV for SBRT to both intact and post-operative spine metastases
- Delineate the spinal cord avoidance structure and understand the importance of precise contouring of this organ at risk
- Contour centrally locally lung metastasis and identify the appropriate organs-at-risk in the thorax.
