Endobiliary Photodynamic Therapy in Cholangiocarcinoma: Clinical Outcomes, Patient Selection, and Procedural Context.
Review in Current oncology (Toronto, Ont.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Endobiliary photodynamic therapy (PDT) in cholangiocarcinoma (CCA) is used mainly for local palliation of malignant biliary obstruction, particularly in extrahepatic and perihilar disease. This Review synthesizes the clinical evidence on endobiliary PDT while using drainage, infection control, stent strategy, light delivery, and systemic-therapy context as an interpretive framework rather than as practice recommendations. This narrative review was informed by targeted searching of PubMed/MEDLINE, Embase, and Web of Science from database inception through to 31 December 2025, supplemented by reference-list screening. We prioritized prospective studies, comparative cohorts, systematic reviews, and relevant guidance documents. Across the literature, the clearest support for PDT concerns selected local biliary palliation, including decompression, stent patency or delayed dysfunction, and symptom relief. Survival signals remain inconsistent: early positive studies contrast with the negative PHOTOSTENT-02 randomized trial and are highly confounded by drainage adequacy, infection control, retreatment strategy, and systemic-therapy access. We therefore interpret PDT as a context-dependent local biliary strategy rather than an established survival-prolonging treatment, and we highlight the clinical variables that make published outcome signals more or less interpretable.
