Neoadjuvant Modified FOLFIRINOX and Stereotactic Body Radiation Therapy in Borderline Resectable Pancreatic Adenocarcinoma

Phase II Study to Evaluate Neoadjuvant Modified FOLFIRINOX and Stereotactic Body Radiation Therapy in Borderline Resectable Pancreatic Adenocarcinoma

Outcome
Stopped earlyPaused due to COVID. A determination was made to stop the study because it would be impossible to reach the 65% resection rate as outlined in the protocol. (Other)

Brief summary public domain (ClinicalTrials.gov)

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.

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.
