简要总结
Surgical resection is the only potentially curative treatment for patients with pancreatic cancer. Patients with BRPC have tumors in close contact with the vasculature but not to the extent that resection is prohibited. Nonetheless, retrospective studies have shown that immediate resection in these patients is associated with an increased risk of positive margins, and a margin positive resection does not improve survival over that of patients with unresectable disease. Moreover, even in those patients where a successful resection is achieved, there is a high rate of early metastatic progression suggesting that micrometastatic disease is often present at diagnosis. Therefore neoadjuvant therapy is likely to improve outcomes in patients with BRPC to increase the likelihood of achieving a margin negative resection, provide early control of occult micrometastatic disease, and select those patients without systemic progression who would benefit from surgical resection.
详细描述
Given the superior outcomes with FOLFIRINOX and the potential for improved local response with SBRT, the investigators propose to evaluate the efficacy of pre-operative modified FOLFIRINOX followed by SBRT in patients with borderline resectable pancreatic adenocarcinoma. The investigators hypothesize that pre-operative modified FOLFIRINOX followed by SBRT will improve the rate of R0 resections compared to historical controls treated with standard gemcitabine-based chemotherapy and fractionated radiation prior to surgery.

结局指标
主要结局
Number of Participants With and Without R0 Resection
时间窗: Up to 40 weeks
The primary outcome of this study is the R0 resection count of patients with BRPC treated with neoadjuvant mFOLFIRINOX and SBRT. R0 resection indicates a microscopically margin-negative resection, in which no gross or microscopic tumor remains in the primary tumor bed. When the study results were entered, rate was replaced with count as the manner in which these data were summarized.
次要结局
- Number of Participants With and Without Pathologic Response to Neoadjuvant Therapy(Up to 40 weeks)
- Number of Participants With and Without Recurrence(Up to 40 weeks)
- Number of Participants: Overall Survival(Up to 2 years)
- Number of Participants Response to Neoadjuvant Therapy Using RECIST(Up to 40 weeks)
- Number of Participants: Progression Free Survival(Up to 2 years)
- Grade 3 or Greater Acute and Late Gastrointestinal Toxicity(Up to 40 weeks)
