3D Specimen Maps for RT Planning

The primary objective of this study is to measure the impact of patient-specific 3D specimen maps on adjuvant radiation treatment volumes and doses to critical organs. All patients will receive standard-of-care post-operative radiotherapy not impacted by the experimental 3D specimen maps. The secondary objective is to demonstrate the feasibility of incorporating 3D specimen mapping tools into post-operative communication, and to determine if utilization of the 3D specimen map improves post-operative communication between surgeons, pathologists, and radiation oncologists.
