Pancreatic gastrointestinal stromal tumour with liver metastasis five years after Whipple?s procedure: A rare case with management challenges

Pancreatic gastrointestinal tumour is an unusual primary tumour of the pancreas. A 31-year-old male came to the clinic with jaundice and weight loss. Cross-sectional imaging showed a mass in the pancreatic uncinate process. Image-guided biopsy revealed gastrointestinal stromal tumour, so pancreaticoduodenectomy was performed, followed by adjuvant Imatinib. The patient had oligo-metastasis in the liver five years post-surgery and underwent liver resection. This is an unusual case where pancreatic GIST presented with metastasis while on adjuvant treatment. Hepatectomy and multimodal therapy increases the survival if the disease is confined to the liver.
