A 55-year-old patient is found to have a 3-cm pancreatic head mass with bile duct and pancreatic duct dilation (double duct sign) on MRCP. CA 19-9 is 1200 U/mL. CT staging shows no vascular involvement and no distant metastases. What is the next best step?
- A Proceed directly to pancreaticoduodenectomy (Whipple procedure) without tissue biopsy if imaging is consistent with resectable cancer ✓
- B Neoadjuvant FOLFIRINOX chemotherapy before resection
- C Endoscopic biliary stenting and preoperative tissue diagnosis followed by Whipple procedure
- D Exploratory laparotomy with intraoperative biopsy and Whipple if margins are negative
Correct answer: A. Proceed directly to pancreaticoduodenectomy (Whipple procedure) without tissue biopsy if imaging is consistent with resectable cancer
Explanation
For resectable pancreatic head cancer with characteristic imaging features (double duct sign, mass, elevated CA 19-9) and no vascular involvement, current NCCN/ESMO guidelines recommend proceeding directly to pancreaticoduodenectomy without mandatory pre-operative tissue biopsy, as biopsy adds risk and rarely changes the surgical decision. Biliary stenting is only indicated if surgery is delayed >2 weeks or the patient is jaundiced and symptomatic. Neoadjuvant therapy is reserved for borderline-resectable or locally advanced disease.
