Carbohydrate antigen 19-9 (CA19-9) response after induction FOLFIRINOX for locally advanced pancreatic cancer identifies patients who may benefit from surgical exploration: multicentre, observational cohort study.
Observational study in The British journal of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundWhich patients with locally advanced pancreatic cancer may benefit from surgical exploration after induction treatment remains debated. The aim of this retrospective cohort study was to identify independent factors for overall survival after surgical exploration for locally advanced pancreatic cancer, which are available at restaging after induction therapy.
methodsConsecutive patients with locally advanced pancreatic cancer from the Trans-Atlantic Pancreatic Surgery cohort who underwent surgical exploration after FOLFIRINOX as induction chemotherapy were included. Multivariable Cox proportional hazards analyses with contour plots were used for the predicted 3-year overall survival in patients who underwent surgical exploration.
resultsOverall, 958 patients with locally advanced pancreatic cancer were treated with FOLFIRINOX as induction therapy. At restaging, 221 patients (23.1%) had metastatic disease (M1) and 724 patients (75.6%) did not have metastatic disease (M0)-234 patients (24.4%) with M0 disease underwent surgical exploration and 490 patients (51.1%) with M0 disease did not undergo surgical exploration; restaging information was not available for 13 patients (1%). The surgical exploration cohort included 213 patients with locally advanced pancreatic cancer, after excluding 21 carbohydrate antigen 19-9 non-producers. The independent prognostic factors for overall survival after surgical exploration were post-induction carbohydrate antigen 19-9 level (HR 1.14 (95% c.i. 1.01 to 1.29)), carbohydrate antigen 19-9 decrease (HR 0.89 (95% c.i. 0.79 to 0.99)), and a WHO performance status of greater than or equal to one (HR 1.71 (95% c.i. 1.21 to 2.42)). Baseline carbohydrate antigen 19-9 was not prognostic for overall survival after surgical exploration (HR 0.98 (95% c.i. 0.90 to 1.07)). The best predicted 3-year overall survival was achieved with a greater than 80% decrease in carbohydrate antigen 19-9 and a post-induction carbohydrate antigen 19-9 less than 50 U/ml.
conclusionCarbohydrate antigen 19-9 after induction therapy, carbohydrate antigen 19-9 decrease, and performance status are independent prognostic factors for overall survival after surgical exploration for locally advanced pancreatic cancer. Three-year overall survival is best in patients with a performance status of zero, a greater than 80% decrease in carbohydrate antigen 19-9, and a post-induction carbohydrate antigen 19-9 level less than 50 U/ml.
