[Clinical and pathological analysis of 114 cases with non-ductal pancreatic adenocarcinoma occupying lesions].
ABSTRACT To improve the diagnosis and treatment of non-ductal pancreatic adenocarcinoma-occupying lesions.
A retrospective analysis was made for 114 cases of pancreatic non-ductal adenocarcinoma-occupying pathologically confirmed lesions.
(1) There were 36 males (31.6%) and 78 females (68.42%); (2) presenting symptoms and signs were abdominal pain (n = 56, 49.1%), back pain (n = 24, 21.1%), weight loss (n = 18, 15.8%) and obstructive jaundice (n = 8, 0.07%); (3) the positive rates of CA19-9, CA242 and CEA were 21.1%, 19.7% and 5.6% respectively; (4) pancreaticoduodenectomy was performed in 26 patients, distal pancreatectomy in 53, tumor enucleation in 15, segmental pancreatectomy in 9, partial resection in 3, duodenum-preserving pancreatic head resection in 1 and palliative surgery (either cholecystojejunostomy anastomosis or gastrojejunostomy) in 7; (5) pathologic analysis revealed 35 solid pseudopapillary neoplasm of pancreas, 28 pancreatic endocrine tumors, 18 focal chronic pancreatitis, 11 serous cystic neoplasms, 9 mucinous cystic neoplasms, 4 pancreatic cysts, 3 acinar cell carcinomas, 2 pancreatic cavernous hemangiomas, 1 sarcoma of pancreas, 1 sarcomatoid carcinoma of pancreas, 1 pancreatic schwannoma and 1 pancreatic neuroblastoma.
The non-ductal pancreatic adenocarcinoma-occupying lesions have no specific clinical presentation or serum tumor marker. An understanding of the natural history of these lesions is important for optimal management.
