Validation of knowledge-based and multicriterial optimization assistive auto-planning algorithms for prostate VMAT radiotherapy using biological optimization.
Article in Journal of applied clinical medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeExternal beam radiotherapy for cancer treatment historically has faced the challenge of delivering sufficient dose to the target while minimizing dose to critical organs. Inverse planning techniques in modulated therapy can improve organ-at-risk (OAR) sparing but require significant human resources and can depend on planner experience. Advances in software and artificial intelligence (AI) have enabled the development of commercial treatment planning systems (TPS) with scripting and auto-planning capabilities, potentially reducing human resource demands and standardizing plan quality. This study aimed to create and validate knowledge-based planning (KBP) and multicriterial optimization (MCO) algorithms for assistive auto-planning of prostate volumetric modulated arc therapy (VMAT) plans using the Elekta Monaco TPS.
methodsOur methodology involved implementing and validating these algorithms retrospectively. We compared dose volume histogram (DVH), generalize equivalent uniform dose (gEUD), and plan quality scores with KBP and MCO algorithms to the clinical plans.
resultsKBP and MCO generated plans on average spared OARs better and on average had better conformity to the targets whilst not sacrificing target coverage. Additionally, algorithm generated plans could be produced within 30 min and were of clinical quality for 72% (KBP) and 78% (MCO) of plans. When comparing the KBP and MCO plans, MCO was dosimetrically slightly superior, slightly faster, and produced plans of clinical quality in more of the validation population than the KBP algorithm.
conclusionThis work showed that it is possible to build KBP and MCO based assistive auto-planning in the Elekta Monaco TPS focusing on gEUD based cost functions. When using the Monaco Scripting functionality, these algorithms could assist in reducing the clinical planning workload while maintaining a patient specific standard of quality.
