Results:

The study was conducted over a period of total 6 months, we have 249 patients whose plans were presented and reviewed in PRM. Out of 249, 139 (55.8%) were male and 110 (44.2%) were female. The setting of treatment was definitive in 101 (40.6%) patients, adjuvant in 144 (57.8%) and neoadjuvant in 4 (1.6%) patients. The majority of our patients were treated with radical intent, i.e., 212 (85.1%). A larger volume of discussed plans comprised of head & neck cancers n= 79 (31.7%), thorax 55 (22.1%) and brain and pelvis each 39 (15.7%). Most of the plans i.e., 190 (76.3%) were based on IMRT/VMAT. The results gathered from our institution showed that changes in 132 (53.1%) of the plans were not suggested changes during PRM. However, in 114 (45.7%) cases, PRM changes were suggested where 78 (31.3%) were minor and 36 (14.5%) were major changes. In majority of cases the changes were suggested in CTV i.e., 62 (24.9%) while PTV was suggested modifications in 21 (8.4%) of the cases during PRM discussion. Among all, head and neck was the region with most frequent PRM changes suggestions 53 (57.6%) followed by pelvis 18 (19.5%).
