Impact of Biopsy Attempts, Race, and Access on Time to Initiation of Treatment for Pancreatic Cancer.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundBiopsy of suspected pancreatic cancer (PDAC) in surgical candidates is informative however not always necessary. Biopsies impact treatment options as histological diagnosis are presently required for neo-adjuvant therapy, but not surgical resection. We explored the impact of pursuing tissue diagnosis by endoscopic ultrasound (EUS) biopsy on time to treatment in patients with resectable and borderline resectable PDAC.
methodsA retrospective review of surgical patients with ultimately proven PDAC was performed (2011-2021). Milestone dates (cancer suspected, biopsy(ies), surgical or neo-adjuvant treatment) were collected. Mann-Whitney-Wilcoxon tests, Pearson's chi-squared tests, Fisher's exact tests, linear regressions, and Cox proportional hazard models were used for data analysis.
resultsAmong 131 resectable and 58 borderline resectable patients, the borderline resectable group underwent more biopsies (1.2 vs 0.7, p < 0.0001), were more likely to undergo biopsy at tertiary care centers (67.2% vs 30.5%, p < 0.0001), and trended toward longer time to treatment (49 vs 44 days, p = 0.070). Significant increases in days to treatment were seen in patients with Black race (29 days, p = 0.0002) and Medicare insurance (22 days, p = 0.038) and no biopsies at a tertiary care center (10 days, p = 0.039). After adjusting for covariates, additional biopsies significantly delayed treatment (1 biopsy: 21 days, p = 0.0001; 2 biopsies: 44 days, p < 0.0001; 3 biopsies: 68 days, p < 0.0001).
conclusionsEUS biopsy significantly impacts time between suspicion and treatment of PDAC. This may be exacerbated by clinical practices increasingly favoring neo-adjuvant therapy that necessitates biopsy-proven disease. Time to treatment may also be impacted by access to tertiary centers and racial disparities.
