Background: Pancreatic adenocarcinoma still has an excessively high mortality rate and resection is the only potentially curative treatment. The postoperative 5-year survival rate is approximately 20% and recurrence develops generally within 2 years. We report a case of a localized recurrent pancreatic adenocarcinoma in the remnant pancreas, 7 years after initial resection.
Case presentation: In 2008 an abdominal computed tomography scan showed a mass in the pancreas of a 70-year-old white woman, who presented with occlusive jaundice and abdominal pain in her right upper quadrant. A pancreatoduodenectomy was performed for a clinically suspected pancreatic adenocarcinoma. Histology confirmed a ductal adenocarcinoma. Afterwards, she received adjuvant chemotherapy with gemcitabine. In 2015 a follow-up positron emission tomography-computed tomography scan showed a single lesion in her remnant pancreas. Subsequently, a partial re-resection was performed. Histology confirmed once again a ductal adenocarcinoma. She received adjuvant chemotherapy with gemcitabine again and is still alive almost 9 years after she had first been diagnosed as having pancreatic cancer.
Conclusions: In selected cases re-resection for pancreatic recurrence is feasible and provides a survival benefit. In cases involving late recurrence, it is difficult to distinguish between true recurrence and the development of a new tumor. In order to detect recurrences at an early stage in long-term survivors, follow-up needs to occur on a regular and long-term basis.
