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.

2 · The registry

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

Aim: Carbon-ion radiotherapy (CIRT) provides superior dose distribution and higher biological effectiveness than conventional X-ray radiotherapy and has emerged as a promising component of multidisciplinary treatment for advanced pancreatic ductal adenocarcinoma (PDAC). However, evidence regarding surgical resection after CIRT remains limited. In this study, we aimed to evaluate the feasibility, histopathological therapeutic response, and oncological outcomes of pancreatic resection after CIRT-based multimodal treatment. Methods: We retrospectively analyzed 12 patients with borderline resectable pancreatic cancer with arterial involvement (BR-A) or unresectable locally advanced PDAC (UR-LA), who underwent surgical resection following CIRT at our institution between January 2016 and June 2025. The surgical outcomes, perioperative morbidity, pathological therapeutic responses, and survival outcomes were assessed. Results: Surgical resection after CIRT was feasible in all patients. The procedures included pancreaticoduodenectomy ( Conclusions: Surgical resection following CIRT-based multimodal treatment is feasible and safe, achieving a favorable histopathological response and durable local control in selected patients with PDAC with arterial involvement.
