What this trial studies

This interventional trial evaluates the feasibility of preoperative chemotherapy combined with proton therapy for patients with borderline resectable pancreatic cancer. Participants will receive gemcitabine and nab-paclitaxel, followed by concomitant proton therapy and capecitabine, before undergoing surgery if feasible. The study aims to assess referral and enrollment procedures, as well as the technical challenges of delivering high doses of proton therapy to complex pancreatic cancer cases. Successful outcomes may lead to a larger study to confirm the effectiveness of this approach in improving surgical resectability and patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with histologically confirmed borderline resectable pancreatic cancer and no distant metastasis.

Not a fit: Patients with significant tumor infiltration of the stomach or duodenum may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and overall survival for patients with borderline resectable pancreatic cancer.

How similar studies have performed: While similar approaches have been explored, this specific combination of proton therapy and chemotherapy for borderline resectable pancreatic cancer is novel and has not been extensively tested.
