DNA ploidy analysis of mucinous cystic tumors of the pancreas. Correlation of aneuploidy with malignancy and poor prognosis.

Abstract:

BACKGROUND:Benign and malignant pancreatic mucinous tumors differ in proliferative activity, production of tumor markers, and expression of growth factors. DNA ploidy is a useful index of aggressiveness and poor survival in ductal adenocarcinoma, but has not been studied in pancreatic cystic tumors. METHODS:The DNA ploidy status of Fuelgen-stained tissue sections of pancreatic mucinous cystic tumors was evaluated by image cytometry and related to clinical outcome obtained by case record review. RESULTS:Ploidy status correlated with malignancy and poor clinical outcome. All benign mucinous cystadenomas (n = 13) were diploid and cured by resection. Patients with diploid cystadenocarcinomas (n = 6) had an 83% survival rate following resection, while patients with aneuploid cystadenocarcinomas (n = 5) all died (four of disease and the fifth of another cause). The difference in survival between the diploid and aneuploid carcinomas was significant (P = 0.04). CONCLUSIONS:DNA ploidy status of pancreatic mucinous tumors by image analysis provides quantifiable information that may be predictive of clinical outcome. DNA aneuploidy appears to be a significant differential factor in pancreatic mucinous tumors and is associated with shortened survival in mucinous cystadenocarcinomas.
