Its long duration and high false-negative rate question its reliability and efficacy. This encouraged us to search for a much quicker and easier method.</p><p><strong>Methods: </strong>The infrared (IR) imaging approach uses the differences in optical density between tumor and healthy tissue to create the sharp contrast in the IR images. The cancerous kidneys were examined after a radical nephrectomy.

Our software highlighted the areas of the IR image that were associated with the healthy and malignant portions, computed their average brightness, and calculated the ratio of the average illumination (RAI) of the malignant area to that of the healthy area. RAI is an interval of numbers obtained as a result of dividing the average brightness of all dark areas in all examined samples by all light areas of all examined samples.

However, the criteria for determining resectability after completion of neoadjuvant therapy (NAT) remain poorly defined. Therefore, this study aimed to investigate the indications for surgical resection as a prognostic factor following NAT with gemcitabine and S-1 (NATGS).</p><p><strong>Methods: </strong>In this retrospective cohort study, we examined patients who underwent curative pancreatic resection following NATGS at our institution between April 2018 and December 2023. After excluding six patients who did not undergo pancreatectomy, the remaining 50 patients were included in the study. Univariate and multivariate analyses were conducted to identify factors potentially associated with survival after NATGS.</p><p><strong>Results: </strong>Post-NATGS CA19-9 levels (< 100 U/mL) were identified as a significant prognostic factor for disease-free survival (DFS) in both univariate and multivariate analyses (hazard ratio (HR) = 11.72251, P < 0.001). For overall survival (OS), both CA19-9 levels (< 100 U/mL) and Duke pancreatic monoclonal antigen type 2 (DUPAN-2) levels (< 150 U/mL) were significant prognostic factors in univariate and multivariate analyses (CA19-9: HR = 17.88, P = 0.002; DUPAN-2: HR = 2.667, P = 0.03). The median DFS was 24.1 months in the low CA19-9 group compared with the 7.1 months in the high CA19-9 group (P = 0.002). The median OS in the low CA19-9 group was not reached, whereas it was 14.7 months in the high CA19-9 group (P = 0.001).</p><p><strong>Conclusions: </strong>The CA19-9 cut-off value is clinically significant for patients undergoing NATGS regimens.

There are no significant differences between actionable mutation carriers and non-carriers concerning histological tumor type, tumor stage, metastasis, smoking habits, and gender.
