Pancreatic body and tail cancers are frequently diagnosed at an advanced stage and are associated with poor prognosis. Systemic chemotherapy remains the standard treatment for unresectable advanced pancreatic cancer, but its effectiveness is often limited by systemic toxicity and suboptimal intratumoral drug concentration.
Splenic artery infusion chemotherapy (SAIC) is a regional treatment strategy that delivers chemotherapeutic agents directly into the arterial supply of the pancreatic body and tail, potentially increasing local drug concentration while reducing systemic exposure. However, clinical evidence comparing SAIC with conventional systemic chemotherapy in patients with advanced pancreatic body and tail cancer remains limited.
This retrospective real-world study aims to compare the efficacy and safety of SAIC and systemic chemotherapy in patients with advanced pancreatic body/tail cancer treated at Sun Yat-sen Memorial Hospital. Clinical data from patients treated between January 2020 and December 2024 will be analyzed. Survival outcomes including overall survival (OS) and progression-free survival (PFS), radiological tumor response, biochemical response, surgical conversion rate, and treatment-related adverse events will be evaluated.
The findings of this study may provide evidence to support the potential clinical value of splenic artery infusion chemotherapy as an alternative treatment strategy for patients with advanced pancreatic body/tail cancer.
