Preoperative Risk Assessment of Pancreatic Fistula Impact on Adjuvant Chemotherapy Delivery After Pancreatoduodenectomy.
Article in Annals of surgical 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
backgroundUp to 40% of patients undergoing pancreatoduodenectomy (PD) for resectable pancreatic ductal adenocarcinoma do not receive adjuvant chemotherapy (aCT). This study aimed to evaluate the impact of postoperative pancreatic fistula (POPF) on aCT delivery and timing and to explore how preoperative variables influence these outcomes according to the occurrence of a POPF.
methodsThis multicenter retrospective study included patients from 25 pancreatic centers. Propensity score matching was performed based on anatomical, biological, and conditional variables. Multivariable regression analyses were used to identify independent predictors of aCT omission and delay.
resultsAmong 1590 patients, 267 (16.8%) developed a POPF. Overall, aCT was administrated in 1,146 patients (72.1%) with a median time to first dose delivery of 56 days (26). After matching, POPF was associated with a significantly lower likelihood of aCT delivery (p < 0.001) and a significant delay in its initiation (p < 0.001). Independent predictors of aCT omission were age ≥ 70 (odds ratio [OR] 2.480, 95% confidence interval [CI] 1.439-4.274; p < 0.001), chronic renal failure (OR 4.554, 95% CI 1.320-15.708; p = 0.016), and chronic obstructive pulmonary disease (OR 2.775, 95% CI 1.021-7.546; p = 0.045) when POPF occurred. In the absence of POPF, apart from age ≥ 70, venous contact (OR 1.574, 95% CI 1.114-2.224; p = 0.010) and tumor size > 20 mm (OR 0.713, 95% CI 0.523-0.972; p = 0.032) were predictors of aCT delivery.
conclusionsPostoperative pancreatic fistula is a key driver of aCT delivery after pancreatoduodenectomy. Its interaction with patient frailty highlights the need for preoperative risk assessment to better select candidates for upfront surgery in resectable pancreatic ductal adenocarcinoma.
