Abstract

Pancreatic ductal adenocarcinoma (PDAC) remains one of the most challenging malignancies, with poor survival rates due to late-stage diagnosis and limited treatment options. Neoadjuvant therapy (NAT), which involves chemotherapy or chemoradiation prior to surgical resection, has emerged as a promising approach to improve resectability and overall survival (OS). The integration of advanced imaging techniques and biomarkers for evaluating the response to NAT is crucial for optimizing therapeutic strategies and surgical outcomes. However, challenges related to the heterogeneity of treatment protocols and the need for predictive biomarkers remain, highlighting the necessity for further clinical trials. The aim is to evaluate the impact of NAT on surgical outcomes and predictive markers in pancreatic cancer. A comprehensive review of the literature was conducted to evaluate the impact of NAT on surgical resectability, survival outcomes, and the role of imaging and biomarkers in assessing therapeutic response. Studies examining the efficacy of NAT in patients with PDAC, the predictive value of serum biomarkers such as carbohydrate antigen 19-9 (CA 19-9), and the utility of advanced imaging modalities such as positron emission tomography/computed tomography with 18F-fluorodeoxyglucose (FDG-PET/CT) were included. NAT has demonstrated significant benefits in downstaging tumors, increasing margin-negative (R0) resection rates, and reducing micrometastatic disease. The use of serum CA 19-9 Levels as a biomarker for response evaluation and imaging modalities such as FDG-PET/CT and magnetic resonance imaging has proven valuable in predicting therapeutic efficacy and guiding surgical planning. Studies have shown that significant reductions in CA 19-9 Levels and favorable metabolic responses on imaging are associated with higher R0 resection rates and longer survival. Furthermore, the integration of multimodal imaging and biomarker assessment has enabled better stratification of patients and more personalized treatment strategies. NAT significantly improves surgical outcomes and survival in patients with resectable and borderline resectable PDAC. Advanced imaging techniques and biomarkers such as CA 19-9 play pivotal roles in evaluating the response to therapy and guiding surgical decision-making. Future research should focus on addressing variability in treatment strategies and developing more reliable predictive biomarkers.

Core Tip: This review highlights the transformative role of neoadjuvant therapy in managing pancreatic ductal adenocarcinoma (PDAC), emphasizing its benefits in improving resectability, enhancing margin-negative resection (R0) rates, and addressing micrometastatic disease. The integration of advanced imaging modalities, such as positron emission tomography/computed tomography with 18F-fluorodeoxyglucose, and biomarkers like carbohydrate antigen 19-9 enables personalized treatment strategies and better surgical planning. By synthesizing recent evidence, the study underscores the critical importance of multimodal approaches, tailored regimens, and emerging therapies in optimizing outcomes for patients with resectable and borderline resectable PDAC.
