NRG Oncology Protocol Development Template for Radiation Therapy — Gastrointestinal Cancer: Lower Gastrointestinal Cancer
Yock A, Parker W · NRG Oncology Medical Physics Subcommittee / Radiation Oncology Committee
DoseLab summary
The template NRG Oncology gives investigators for the radiation therapy section of a lower GI (rectal) trial. Its example uses 45 Gy in 25 fractions with a 5.4 Gy sequential boost, or a single-phase simultaneous integrated boost, and recommends rigid registration of MRI and PET with the planning CT. Values in it are examples to be edited for each trial.
Why this is useful
NRG's model radiation section for a rectal trial — simulation, MRI and PET fusion, target definitions, structure names and example compliance criteria for sequential-boost or SIB plans.
