简要总结
This single-center, prospective proof-of-concept study is designed to evaluate the surgical outcomes and clinicopathologic results of neoadjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) in conjunction with perioperative systemic chemotherapy (SCT; neoadjuvant and adjuvant) and pancreaticoduodenectomy (PD) in a small cohort of patients having T1-T3 resectable pancreatic ductal adenocarcinoma (PDAC) with one or more high-risk clinical features. The investigators hypothesize that HIPEC administered in this clinical course will reduce postoperative peritoneal disease recurrence. The investigators also expect that local recurrence of disease will be reduced. The primary aim of this study is to compare 2-year peritoneal disease-free survival between patients receiving the experimental therapy (neoadjuvant HIPEC + SCT + PD) with historical controls receiving standard therapy (SCT + PD). Secondary aims are to determine the clinical feasibility and outcomes of neoadjuvant HIPEC for resectable PDAC using patient demographics and disease characteristic data.

研究组 & 干预措施
HIPEC
Immediately following laparoscopy for diagnosis and staging of disease, closed neoadjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) will be performed using the anatomical site of the laparoscopic procedure in the same operative encounter. Perfusion will be initiated with 4-6 L of 1.5% dextrose at a 500 mL/min flow rate with manual agitation of the abdominal wall. Once the temperature in the abdomen becomes stable above 40°C, perfusate volume will be reduced to 1.5 L/m sq, and gemcitabine (GEMZAR®) will be instilled into the abdomen (1000 mg/m sq) for 90 min. Neoadjuvant chemotherapy with gemcitabine will be administered prior to open pancreaticoduodenectomy by the standard Whipple or pylorus-preserving approach. Adjuvant systemic chemotherapy with gemcitabine will be administered for 6 months (including period of neoadjuvant therapy) according to established institutional protocol.

Historical Control
Case-matched historical controls will have received neoadjuvant chemotherapy with gemcitabine prior to open pancreaticoduodenectomy (PD) by the standard Whipple or pylorus-preserving approach. Adjuvant systemic chemotherapy (SCT) with gemcitabine will be administered for 6 mo (including period of neoadjuvant therapy) according to established institutional protocol.

结局指标
主要结局
Peritoneal disease-free survival
时间窗: 2 years
Peritoneal disease-free survival is defined as the time between staging laparoscopy confirming no peritoneal disease (at the time of HIPEC treatment) and regional recurrence of pancreatic ductal adenocarcinoma on the peritoneal surfaces as determined by diagnostic imaging. This definition is exclusive of recurrence status in the pancreatic remnant after resection.
次要结局
- Overall survival(1, 2, 3, 5 years)
- Postoperative morbidity(1 and 3 months)
- Local disease-free survival(2 years)
- Postoperative mortality(1 and 3 months)
