TROG 2019 SBRT Pancreas Plan Study (High Performer Summary)

ProKnow and TROG offer our sincere thanks and congratulations to all those who participated in this latest international plan study. This was an SBRT pancreas case with challenging metrics and plan scoring based on the MASTERPLAN protocol.

In this article, we present a list of participant names, institutions, and plan details for some of the highest performers for this study. The TROG team presented results on March 15 at their meeting in Australia, but there they announced only the names of the top scorers in the Australia and New Zealand regions. Here, we publish the following:

1. Top 20% overall by total plan score
2. Top 10 VMAT
3. Top 3 IMRT
4. Top 3 Robotic
5. Top 3 Proton
6. Top 5 Students

Table 1. Top 20% across all submitted plans, based on total plan score.

Planner information, plan details, and performance summary are given. The #TH1 and #TH2 columns represent the number of metrics (out of 25) where the minimum threshold for scoring and ideal threshold were met, respectively (see note, below), and the final column is the total plan score.

Note: We heard that some participants were confused by the “min req” terminology printed on the plan scorecard summaries in each row, i.e. per metric. For each metric, that was meant as the minimal threshold for scoring for that metric but did not imply that threshold absolutely had to be met for the plan to be considered. Each metric’s relative importance/priority was captured by each metric’s weight (max points) and score function. We will make this more clear in future plan studies, and we will also introduce the option for plan study clinical teams to specify “critical metrics” for which the lower threshold value must be met or else the total plan score will be zero.
