Adding-on nivolumab to chemotherapy-stabilized patients is associated with improved survival in advanced pancreatic ductal adenocarcinoma

Background Immune checkpoint inhibitors (ICIs) are rarely used to treat advanced pancreatic ductal adenocarcinoma (PDAC) due to marginal efficacy. Patients and methods This study included 92 consecutive patients diagnosed with advanced or recurrent PDAC who received nivolumab-based treatment. Univar...

description Background Immune checkpoint inhibitors (ICIs) are rarely used to treat advanced pancreatic ductal adenocarcinoma (PDAC) due to marginal efficacy. Patients and methods This study included 92 consecutive patients diagnosed with advanced or recurrent PDAC who received nivolumab-based treatment. Univariate and multivariate analyses were used to identify prognostic factors. A control group of 301 patients with PDAC who achieved disease control with palliative chemotherapy but without ICIs was selected for comparison using propensity score matching (PSM). Results The median overall survival (OS) since nivolumab treatment was 15.8 (95% confidence interval [CI], 12.5–19.0), 2.4 (95% CI 1.2–3.6), and 1.1 (95% CI 1.0–1.2) months in patients who received add-on nivolumab after achieving disease control with chemotherapy, in those who received concomitant nivolumab and chemotherapy without prerequisite confirmation of disease control, and in those who received nivolumab without concomitant chemotherapy, respectively ( P
