Pancreatic Adenocarcinoma Neoadjuvant Chemotherapy Before Surgery

Официальное название

MFOLFIRINOX or Gemcitabine / Nab-paclitaxel Followed by Pancreatectomy for Patients with Borderline Resectable Pancreatic Adenocarcinoma. a Pilot Feasibility Study.

Обзор

This is a single-arm, single-center feasibility trial of patients with borderline resectable pancreatic adenocarcinoma receiving chemotherapy with mFOLFIRINOX or gemcitabine / nab-paclitaxel followed by pancreatectomy.

Подробное описание

Borderline resectable pancreatic adenocarcinoma infiltrates into adjacent vascular structures to an extent such that complete macroscopic resection is technically feasible, but an R0 resection poses a challenge when surgery is the primary therapy. Therefore, a different management strategy may be beneficial.

The primary outcome of the PANCREAS trial is defined as the proportion of eligible patients enrolled in the study over an 18-month period and the proportion of patients who complete the protocol (neoadjuvant therapy and pancreatectomy). Certain modifications of the neoadjuvant therapy protocol are expected and allowed, and the primary feasibility outcome will be one of the following: stop, main study non-feasible; continue with protocol modifications; or continue without modification. A safety analysis will be performed after first 15 patients are enrolled and complete neoadjuvant therapy and surgery. Patients enrolled in this trial will undergo interventions in the following order: neoadjuvant chemotherapy, re-staging CT scan, pancreatectomy and adjuvant chemotherapy. Postoperative mortality will be recorded up to 90 days after surgery. Patients will be followed every four months with a CT scan of the chest/abdomen for two years after resection or until evidence of disease recurrence. Patients who do not undergo surgical resection will be followed for two years after accrual (duration of study period) or until evidence of disease progression or death.
