Stereotactic Ablative Radiotherapy for Oligometastatic Pericolonic Soft Tissue Metastases Using Daily Cone-Beam Computed Tomography-Guided Online Adaptive Radiotherapy.

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
A 74-year-old woman with pathologic T4a N1 M0 adenocarcinoma of the cecum, initially treated with right hemicolectomy, developed rising serum carcinoembryonic antigen levels while receiving adjuvant chemotherapy. Re-staging investigations demonstrated two soft tissue metastases in the right abdomen comprised of a retrocolic lesion immediately posterior to the colon and a retroperitoneal lesion with no other sites of metastases. The patient was treated with stereotactic ablative radiotherapy (SABR) to a dose of 40 Gy in five daily fractions to both pericolonic soft tissue metastases simultaneously. A standard volumetric modulated arc therapy (VMAT) plan had suboptimal dose coverage of the retrocolic metastasis adjacent to the colon, so cone-beam computed tomography (CBCT)-guided online adaptive radiotherapy (ART) was employed to maximize radiation dose to the tumors due to the radioresistant histology. An intensity-modulated radiotherapy (IMRT) plan was created using artificial intelligence tools integrated with the treatment unit. Median contouring and plan creation for each fraction was 21.5 minutes (range 14.9-28.1). For the retrocolic metastasis, compared to the standard VMAT plan, the CBCT-guided online ART plan improved coverage of the gross target volume by the prescription dose from 80.0% to 99.7%. SABR to pericolonic soft tissue metastases was feasible using CBCT-guided online ART and can significantly improve target volume coverage when targets are adjacent to mobile normal organs, which may be particularly important for radioresistant histologies for local control.
