Pain response after palliative-intent radiotherapy for pancreatic cancer: a systematic review.
Synthesis in International journal of clinical oncology, 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
backgroundTo date, no review has specifically focused on palliative-intent radiotherapy (RT) for pancreatic cancer (PC)-related pain. This study aimed to evaluate the pain response after palliative-intent RT for PC-related pain.
methodsA comprehensive literature search was conducted using PubMed, Ichushi-Web, and the Cochrane Library for studies published between 1971 and 2024. Studies in which palliative-intent RT was administered for PC-related pain were included. Extracted Data were independently assessed by three reviewers.
resultsOf the 629 studies identified through the database search, 11 met the inclusion criteria. The most frequently used palliative-intent RT schedules were 30 Gy in 10 fractions for conventional RT and 25 Gy in a single fraction for stereotactic body radiotherapy (SBRT). In addition, 8 Gy once weekly (24 Gy in 3 fractions) RT has also been reported. Because the methods used for pain assessment varied across the included studies, a meta-analysis was considered inappropriate. Pain associated with PC improved following palliative-intent conventional RT (pain response rate, 69-94%), palliative-intent SBRT (pain response rate, 53-90%), and 8 Gy once weekly RT (pain response rate, 80%). A few grade ≥ 3 gastrointestinal adverse events were reported (< 10%).
conclusionPalliative-intent RT appears to be a promising approach for alleviating PC-related pain. However, the current evidence is heterogeneous in terms of target selection and dose-fractionations. Further studies, including randomized controlled trials, may help identify optimal treatment strategies.
