NCT07326150
This study is a single-center, observational clinical trial designed to enroll a total of 70 pancreatic cancer patients. Tumor tissue sections from 60 patients will be retrospectively collected to establish a treatment response prediction model using spatial transcriptomics and other analyses. Fresh tumor tissue and blood samples from 10 patients will be prospectively collected to establish pancreatic cancer organoids and humanized immunocompetent mouse models for functional validation and exploration of the underlying molecular mechanisms.
NCT06496373
This study primarily aims to assess the safety and tolerability of XP-004 personalized mRNA vaccines encoding tumor neoantigens combined with PD-1 inhibitor as adjuvant therapy for chemotherapy-intolerant patients following radical pancreatic cancer resection. Secondary objectives focus on evaluating preliminary efficacy through three parameters: 1) XP-004-induced antigen-specific CD4+/CD8+ T cell activation levels, 2) recurrence-free survival (RFS), and 3) overall survival (OS) in post-operative pancreatic cancer patients receiving this combination therapy.
NCT07157605
The goal of this observational study is to determine how often lymph node metastases occur in the splenic hilum and surrounding fat in patients with left-sided pancreatic cancer. The main question the study aims to answer is: Is spleen removal necessary in all cases, or is the risk of lymph node metastases in the fat around the spleen low enough to reconsider this standard practice? Currently, spleen removal is part of the standard treatment for patients with left-sided pancreatic cancer to ensure that any potential lymph node metastases in the surrounding fat are also removed. However, the likelihood of metastases in this area is low, and spleen removal carries risks. This study is a first step toward changing the treatment approach. If the findings show that metastases in the fat around the spleen are rare, the next step will be a randomized trial to further investigate whether spleen removal is necessary.

Pancreatic cancer is one of the most treatment resistant malignancies, often diagnosed at a late stage and associated with poor survival. The 5-year overall survival rate remains around 10%. Prognosis is affected by multiple factors including tumor stage, biology, treatment response, and anatomical location. Distal (left-sided) pancreatic cancer, originating from the body or tail of the pancreas, accounts for approximately 20-25% of all pancreatic cancers and has been associated with worse survival than pancreatic head cancer, even when adjusted for stage. This may be due to histological, molecular, and embryological differences, and varied systemic therapy responses. Neoadjuvant chemotherapy has become increasingly important in managing pancreatic cancer. It may improve outcomes by reducing tumor size, allowing for more complete (R0) resections, treating micrometastatic disease early, and identifying patients unlikely to benefit from surgery. While neoadjuvant therapy is recommended for borderline resectable and locally advanced tumors, randomized trials have not shown benefit for patients with upfront resectable pancreatic head cancer. Importantly, no randomized controlled trials have investigated the benefit of neoadjuvant treatment specifically in patients with upfront resectable left-sided pancreatic cancer, despite its distinct biology and worse prognosis. Retrospective data suggest neoadjuvant therapy may improve survival in left-sided tumors. A recent multicenter study reported significantly longer overall survival in patients treated with neoadjuvant therapy compared to upfront surgery alone. However, prospective randomized data are lacking. This multicenter randomized trial aims to assess whether patients with resectable left-sided pancreatic cancer benefit from neoadjuvant chemotherapy compared to upfront surgery. The study will reflect real-world clinical practice by allowing both commonly used regimens-FOLFIRINOX and Gemcitaine-Nab-paclitaxel -as neoadjuvant options. Previous studies have shown these regimens to be similarly effective, and switching between them due to toxicity or progression is feasible and does not seem to impair surgical outcomes or survival. This study aims to evaluate the benefits of neoadjuvant chemotherapy before surgery in a prospective multicenter randomized setting for resectable left-sided pancreatic cancer patients.
