title: Characteristics of cystic neoplasms of the pancreas and results of aggressive surgical treatment.
abstract: Twenty-one patients with pancreatic cystic neoplasms (PCNs) were treated from 1970 to 1991. Their mean age was 54 years (range: 30 to 78 years), and 15 (71%) were women. Symptoms were present for a mean of 18 months (range: 5 to 60 months) and included pain (95%), abdominal mass (52%), weight loss (38%), and jaundice (14%). Nine patients had had previous operations and were either misdiagnosed or incorrectly treated; another seven patients had preoperative misdiagnoses of pseudocysts. There were six (29%) serous cystadenomas and two (10%) mucinous cystadenomas. These were treated by excision (n = 2), distal pancreatectomy (n = 5), or pancreatoduodenectomy (n = 1). No recurrence or malignant degeneration occurred during the mean follow-up of 9 years (range: 1 to 19 years). There were 13 (62%) patients with mucinous cystadenocarcinomas. Of these 13 patients, 3 had unresectable tumors, underwent palliative procedures, and died at 4, 7, and 9 months, respectively. Ten patients underwent pancreatoduodenectomy (n = 4), distal (n = 4) pancreatectomy, or total (n = 2) pancreatectomy: 1 died of recurrence (survival: 8 months), and the remaining 9 patients had a mean survival of 6 years (range: 2 to 20 years) without recurrence. This experience suggests that patients with PCNs have a good prognosis and are curable if the cysts are diagnosed early and completely resected.
