Disparities in the diagnosis and management of exocrine pancreatic insufficiency in resectable vs metastatic pancreatic cancer.
Article in The oncologist, 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
backgroundExocrine pancreatic insufficiency (EPI), a common complication of pancreatic cancer (PC), reduces quality of life and may shorten survival. While pancreatic enzyme replacement therapy (PERT) improves symptoms and outcomes, real-world patterns of EPI workup and PERT use across PC subtypes remain poorly described in the United States. PATIENTS AND
methodsWe retrospectively analyzed 250 patients with resectable or metastatic PC from a single institution's prospectively maintained registry (2013-2018), collecting data on clinical characteristics, EPI symptoms, fecal elastase testing, and PERT prescriptions. In addition to the retrospective analysis, a quality improvement intervention for EPI management was implemented (1/2021-1/2023), and outcomes were analyzed.
resultsAmong 250 patients, 97 underwent surgery for resectable disease and 153 received non-surgical management for metastatic PC. Exocrine pancreatic insufficiency symptoms occurred in 58% of metastatic and 68% of surgical patients. Fecal elastase testing was rarely performed (2% vs 9%, respectively). Pancreatic enzyme replacement therapy was prescribed to 46.5% of metastatic and 84% of surgical patients, but average doses were suboptimal (18 500 vs 20 000 USP units per meal; recommended: ≥40 000). Among those on PERT, symptom resolution was reported in 33% of metastatic and 44% of surgical patients. Contrasting with results from the retrospective analysis, the quality improvement intervention led to 90% of 41 participants being prescribed PERT at an average dose of 44 700 USP units per meal. Treated patients (74.1%) experienced complete resolution of EPI symptoms.
conclusionDespite prevalent EPI symptoms in PC patients, fecal elastase testing was infrequently utilized, and PERT was often underdosed. Educational initiatives are needed to improve guideline adherence and optimize outcomes.
