NeoFOL-R Trial (Perioperative Versus Adjuvnat FOLFIRINOX in Resectable Pancreatic Cancer)

Prior treatment

• Those evaluated as borderline resectable or locally advanced pancreatic cancer in preoperative imaging examination (The resectability assessment depends on the presence of major vessel invasion, while invasion of adjacent organs is excluded from the criteria) B. Patients with a history of previous pancreatic surgery C. Patients with a history of previous chemotherapy or radiation therapy for pancreatic cancer D. Patients with distant metastases or recurrent pancreatic cancer E. Pancreatic body or tail cancer requiring combined resection of adjacent organs (stomach or kidney) (except for the adrenal gland) F. Patients within five years of diagnosis of other organ malignancies (with the exception of adequately treated non-melanoma skin cancer and carcinoma in situ without evidence of disease) G. Pregnant and lactating women H. Serious concomitant systemic disorders, including active or ongoing systemic infections, symptomatic congestive heart failure, unstable angina, clinically significant cardiac arrhythmias, psychiatric disorders, or uncontrolled comorbid conditions that may limit compliance with study requirements, or any medical condition that, at the discretion of the investigator, could compromise patient safety, interfere with the assessment of safety and efficacy, or hinder participation in the clinical trial.
