BACKGROUND/AIMS: There has been no thorough clinicopathological analysis of a large number of cases with mucin-producing tumor of the pancreas. The aim of this study was to investigate the clinicopathological features of and therapeutic strategy for this ailment.
METHODOLOGY: Two hundred and fifty-nine cases of mucin-producing tumor of the pancreas were analyzed clinicopathologically.
RESULTS: Mucin-producing tumor of the pancreas was found in 177 males and 82 females (M:F=2.2:1). The mean age was 65.5 years. Jaundice, diabetes mellitus and a past history of pancreatitis were found in 15-19% of the cases. The tumor was most frequently (62%) found in the head of the pancreas. Pathologically, hyperplasia or adenoma was found in 58 cases, and adenocarcinoma in 160 cases. Five-year survival rate by the Kaplan-Meier method was 82.6% in all of the cases, and the post-operative survival curve was much better in cases with this type of carcinoma than in cases with ordinary pancreatic duct cell carcinoma (5-year survival rate: 17.3%). Organ-function preserving procedures, such as duodenum preserving subtotal resection of the head of the pancreas or spleen preserving distal pancreatectomy, might be recommended for this disease without infiltration.
CONCLUSIONS: Mucin-producing tumor has unique clinicopathological characteristics, such as the dilated main pancreatic duct or branches, dilatation of the orifice of the papilla of Vater, or a good prognosis. Organ-function preserving procedures should be recommended in some cases with this ailment.
