1 · What the graph read from it

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.

Abstract

purposeThis study reports the first-in-human use of a linear accelerator-based boron neutron capture therapy (BNCT) system and the first treatment of patients with scalp-angiosarcoma with accelerator-based BNCT. PATIENTS AND

methodsA single-center open-label phase I clinical trial has been conducted using the system since November 2019. Patients with a localized node-negative scalp-angiosarcoma along with the largest diameter of the tumor ≤ 15 cm who refused primary surgery and chemotherapy were enrolled. After administration of boronophenylalanine (BPA), a single treatment of BNCT with the maximum dose delivered to the skin being 12 Gy-Eq was performed. The safety and effectiveness of accelerator-based BNCT therapy for localized scalp angiosarcoma were evaluated.

resultsScalp-angiosarcoma of the two patients did not develop the dose-limiting toxicity in the clinical trial. They reached CR within half a year and did not exhibit in-field failure 20 months after BNCT without any severe treatment-related adverse events. Although a grade 3 adverse event of an asymptomatic but increased serum amylase level was noted in both patients, it relieved without any treatment. Additionally, no severe acute dermatitis was observed for both patients, which is typically seen with conventional primary radiotherapy.

conclusionsIt was suggested that BNCT would be a promising treatment modality for scalp-angiosarcoma, which is difficult to treat.
