With improved target conformality, the transition to IMRT for nasopharyngeal cancer (NPC) has moved contouring accuracy and consistency to the forefront. At NUH, IMRT for NPC was implemented in 2005, with more than 70 patients treated since then. The objective was to measure the accuracy and variability of contouring organs at risk (OAR) over time. The first 10 patients, 5 from each of the two head and neck (H&N) Radiation Oncologists, treated by IMRT in 2005 formed cohort A. Ten patients… CONTINUE READING
