Morbidity among long-term survivors after pancreatoduodenectomy for pancreatic adenocarcinoma.
BACKGROUND
Because pancreatoduodenectomy for pancreatic adenocarcinoma is focused on disease-free and overall survival, morbidity among long-term survivors is not well described. This study sought to evaluate outcomes for long-term survivors of pancreatic cancer after pancreatoduodenectomy.


METHODS
The authors identified 29 patients from their prospectively collected database of patients with pancreatic adenocarcinoma who had undergone pancreatoduodenectomy and were without evidence of disease during at least 3 years of follow-up evaluation. Demographics, treatment, and pathologic characteristics were collected for review. Data with regard to long-term sequelae also were collected, focusing on those complications requiring additional procedures and on the development of metachronous cancers.


RESULTS
The median follow-up period was 83 months, with 62 % of patients still alive. All patients received an R0 resection, and 34 % of the patients had N1 disease. For 42 % of the patients, no significant subsequent sequelae occurred. In the four remaining patients (14 %), ascites developed, requiring repeated paracentesis or Denver shunt, with a median time to development (MTD) of 63 months. Six patients (21 %) experienced a biliary stricture requiring stent placement (MTD, 56 months). One patient experienced portal venous thrombosis requiring a venous stent (MTD, 52 months), and four patients (14 %) experienced clinically significant ulcers (MTD, 52 months). With regard to metachronous cancers, two patients experienced subsequent lymphomas (MTD, 92 months).


CONCLUSIONS
Long-term survivors among patients who undergo pancreatoduodenectomy for pancreatic adenocarcinoma can experience significant late sequelae, which often manifest more than 3 years after surgery. As such, continued follow-up evaluation and counseling are warranted.
