Photodynamic therapy with local-targeted perfusion for recurrent tracheal adenoid cystic carcinoma achieving 12-year survival: A case report.
Article in Oncology letters, 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
Adenoid cystic carcinoma (ACC) is a malignant tumor that originates from the ductal epithelium of the secretory glands and has a tendency for perineural invasion. Primary tracheal ACC is a clinically rare subtype, with an annual incidence rate of 0.04-0.2%, accounting for <1% of all tracheal malignant tumors. Surgery and radiotherapy remain the standard treatments, but there are clinical challenges with the high recurrence rate. The present article reports the case of a patient who relapsed after partial tracheal resection and was considered inoperable. Bronchoscopy was used for airway assessment and interventional treatment, including submucosal injection and photodynamic therapy. After this intervention, the overall survival of the patient exceeded 12 years.
