We evaluated predictive factors that are routinely collected during clinical care with the aim to support an informed and shared decision.  \nMETHODS: In a prospective study across 35 German sites, 151 patients with PC previously treated with gemcitabine/nab-paclitaxel were enrolled and 146 patients received biweekly nanoliposomal irinotecan/5-fluorouracil/FA. We investigated whether time-totreatment-failure of 1st-line (TTF1) predicts 2nd-line treatment outcome. Patients were stratified into three equal cohorts based on TTF1 . Primary endpoint was TTF2, with secondary endpoints including overall survival (OS) and growth modulation index (GMI) . RESULTS: Median TTF2 was 3.71 months (95% CI 2.50–4.11) . Median OS was 7.72 months (95% CI 6.11–9.00) . TTF1 did not predict TTF2 or OS (HR 0.93, 95% CI 0.58-1.47 . Baseline parameters significantly associated with TTF2 and OS included neutrophil count, CRP levels, and liver metastases, whereas ECOG performance score (PS) was primarily associated with OS and to a lesser extent with TTF2 . During treatment, patients with a CA 19-9 reduction of ≥25% had significantly improved TTF2 and OS (p \u003C 0.001) . CONCLUSION: TTF1 is not predictive of TTF2 or OS. Therefore, 2nd-line treatment should not be withheld irrespective of duration of TTF1 . CA 19-9 dynamics can be used to predict further benefit to some extent.  \nCLINICAL TRIAL REGISTRATION: EudraCT: 2016-005147-17; [ClinicalTrials.gov:](ClinicalTrials.gov:) NCT03468335.  \nBritish Journal of Cancer (2026) 134:85–91; [https://doi.org/10.1038/s41416-025-03188-x](https://doi.org/10.1038/s41416-025-03188-x)  \nBACKGROUND  \nDuctal pancreatic adenocarcinoma (PC) is the fifth leading cause of cancer-related deaths worldwide, with ~411,600 fatalities each year [1] . At diagnosis, less than 30% of patients qualify for a surgical resection, which is the only chance for cure. Median survival for patients with unresectable disease ranges from 8 to 12 months, with even lower survival for those with metastases. In selected patients, 1st-line systemic chemotherapy is well established. It prolongs median survival up to 11.1 months [2–4], and about 40–50% of these patients are still able to continue to 2ndline therapy [5] . Targeted treatment options are available for a  \nsmall subset of patients after molecular profiling, with a high potential for future KRAS-directed therapies [6] .  \nFor advanced PC, 2nd-line chemotherapy with nanoliposomalirinotecan (Nal-IRI) in combination with 5-fluorouracil (5-FU)/folinic acid (FA) increases median overall survival (OS) from 4.2 months to 6.1 months compared to 5-FU/FA alone [7] after failure of agemcitabine-based regimen. However, some grade 3/4 toxicities are reported (e.g. 13% diarrhoea and 14% fatigue) . A novel formulation of liposomal irinotecan/5-FU/FA showed similar results, with an OS of 7 .4 months (95% CI 6 .1–8.4) in the PANHEROIC-1 trial [8] .  \n1Caritasklinikum St. Theresia and Saarland University Medical Center, Saarbrücken and Homburg, Germany. 2St. Elisabeth-Krankenhaus, Köln, Germany. 3AIO-Studien-gGmbH, Berlin, Germany. 4Staburo GmbH, München, Germany. 5Schwarzwald-Baar-Klinikum Villingen-Schwe","cbCaicjreTKMLjh9","https://ap.wps.com/l/cbCaicjreTKMLjh9","pdf",505433,"English","# Background\n## Methods and endpoints\n## Results\n## Conclusion","[{\"question\":\"What was the main goal of the study in patients with advanced pancreatic adenocarcinoma?\",\"answer\":\"To identify predictive factors, collected during routine clinical care, that can support informed decisions about 2nd-line chemotherapy outcomes.\"},{\"question\":\"Does time-to-treatment-failure of 1st-line therapy (TTF1) predict 2nd-line outcomes?\",\"answer\":\"No. TTF1 did not predict 2nd-line TTF2 or overall survival (OS).\"},{\"question\":\"Which baseline factors were associated with TTF2 and OS?\",\"answer\":\"Neutrophil count, CRP levels, and liver metastases were significantly associated with TTF2 and OS, while ECOG performance score was mainly associated with OS and to a lesser extent with TTF2.\"}]","Predictive criteria for overall survival and treatment duration of 2nd-line chemotherapy in patients with advanced pancreatic adenocarcinoma (AIO-PAK-0216) | PDF",1790651633,18]
