Impact of Sarcopenia During Induction Treatment in Patients With Unresectable Locally Advanced Pancreatic Cancer.
Article in Annals of gastroenterological surgery, 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
Background: Chemotherapeutic advances have increased opportunities for conversion surgery (CS) in unresectable locally advanced (UR-LA) pancreatic cancer (PC). However, the optimal indications for CS remain unclear. Sarcopenia has been associated with poor outcomes in PC, except UR-LA PC. Herein, we aimed to evaluate the impact of sarcopenia on the prognosis of patients with UR-LA PC. Methods: In this retrospective study, we reviewed consecutive patients with UR-LA PC who had received chemo(radio)therapy as an initial treatment between 2015 and 2023. We examined relevant clinical variables and CT findings at initial diagnosis and at 6 months after starting treatment. Results: Ten of the 41 patients had undergone CS. Tumor size at 6 months, clinical lymph node metastasis at diagnosis, and changes in sarcopenia over 6 months were associated with overall survival (OS) (multivariate analysis: hazard ratio = 3.25, 2.79, and 3.51, respectively). In the entire cohort, patients without any of these three factors had significantly better OS than those with one or more (median OS: 30.3 months vs. 17.3 months, Conclusions: The impact of change in sarcopenia on prognosis was demonstrated in patients with UR-LA PC. Although, given the limited number of cases, CS might provide a survival benefit in carefully selected patients without prognostic factors such as tumor size at 6 months, clinical lymph node metastasis at diagnosis, and the rate of change of the psoas muscle mass index (PMI).
