“…Contrast agents and metallic markers have been used commonly to demonstrate the anatomy during simulation to precisely delineate the target volume and to increase the probability of tumor control. 33 Valicenti et al 34 presented a study in which seven radiation oncologists delineated the prostate in groups of patients with and without contrast medium. The study concluded that the use of urethral and bladder contrast improved the reliability of localizing the prostate.…”

PURPOSE To evaluate and report the frequency of changes in radiation therapy treatment plans after peer review in a simulation review meeting once a week. MATERIALS AND METHODS Between July 1 and August 31, 2016, the radiation plans of 116 patients were discussed in departmental simulation review meetings. All plans were finalized by the primary radiation oncologist before presenting them in the meeting. A team of radiation oncologists reviewed each plan, and their suggestions were documented as no change, major change, minor change, or missing contour. Changes were further classified as changes in clinical target volume, treatment field, or dose. All recommendations were stratified on the basis of treatment intent, site, and technique. Data were analyzed by Statistical Package for the Social Sciences and are presented descriptively. RESULTS Out of 116 plans, 26 (22.4%) were recommended for changes. Minor changes were suggested in 15 treatment plans (12.9%) and a major change in 10 (8.6%), and only one plan was suggested for missing contour. The frequency of change recommendations was greater in radical radiation plans than in palliative plans (92.3% v 7.7%). The head and neck was the most common treatment site recommended for any changes (42.3%). Most of the changes were recommended in the technique planned with three-dimensional conformal radiation therapy (50%). Clinical target volume (73.1%) was identified as the most frequent parameter suggested for any change, followed by treatment field (19.2%) and dose (0.08%). CONCLUSION Peer review is an important tool that can be used to overcome deficiencies in radiation treatment plans, with a goal of improved and individualized patient care. Our study reports changes in up to a quarter of radiotherapy plans.

“…This conclusion was in consistency with previously published reports about pelvic RT for carcinoma uterus & prostate. [16][17][18] On analysis of the acute gastro-intestinal toxicities in the two arms, we found the toxicities were equal in both arms. Grade III/ IV toxicities were approximately 5% in both the arms.…”

“…Used in diagnostic radiology for over a century (1), contrast media has long been considered a valuable aid during radiation therapy simulation, which involves the acquisition of images for treatment planning purposes. For example, as part of radiation therapy simulation using plain film radiographs, contrast media were often administered by mouth, urethra, vagina, and rectum, to help delineate radiotherapeutic targets and avoidance structures (2). In the 1980s, the development of intravenous contrast-enhanced computed tomography (CT) allowed the acquisition of more sophisticated images at the time of simulation, which have in turn facilitated the application of more advanced radiation therapy techniques (3).…”

Purpose Intravenous contrast media (ICM) administration is recommended as part of radiation therapy (RT) simulation in a variety of clinical scenarios, but can cause adverse events. We sought to assess radiation oncology resident knowledge about ICM, and to determine if an educational intervention (EI) could improve this level of knowledge. In conjunction, we retrospectively analyzed risk factors and adverse events related to ICM use before and after the EI to determine whether any improvements in patient outcomes could be realized. Methods Over 2 years, 21 residents in radiation oncology at Memorial Sloan-Kettering Cancer Center (MSKCC) participated in a pretest-EI-posttest study based on the ACR’s Manual on Contrast Media. Medical and RT records were reviewed, and ICM use, risk factors and adverse events were recorded. Results There was no significant difference in resident understanding of ICM use in residents of different years of training (p=0.85). Understanding of ICM use increased in residents that attended the EI (p<0.05), but this was not sustained 1 year after the EI (p=0.48). Of the 6852 RT simulations that were performed at MSKCC, 1350 (19.7%) involved ICM. Mild adverse events occurred in a few patients (<5%) simulated with ICM, but there was no difference in the number of risk factors or adverse events before and after the EI. Conclusions The EI effectively improved short-term understanding of ICM use. However, the effect was not sustained. The frequency of adverse events related to ICM use was small and not significantly impacted by the EI.
