Pathological complete response in pancreatic adenocarcinoma with FOLFIRINOX.

The report describes a patient who presented to our centre with abdominal pain and significant weight loss due to adenocarcinoma of the tail of the pancreas. The cancer was deemed as 'resectable disease associated with morbid surgical outcomes' due to the local involvement of the vessels and adjacent organs. Given the patient's excellent performance status, the patient underwent neoadjuvant chemotherapy with folinic acid, fluorouracil, irinotecan and oxaliplatin to downstage the tumour for less morbid surgical resection. The patient underwent 12 cycles of chemotherapy with serial imaging which demonstrated positive response to treatment and surgical resection was performed. Surgical pathology revealed no residual tumour and imaging was negative for any extrapancreatic tumour metastasis. This is an unusual case as pancreatic malignancy is usually lethal with poor survival outcomes.
