[Analysis of Ki-ras in pancreatic fluid aspirate. A new diagnostic possibility in investigation of pancreatic cancer].
The prognosis for pancreatic carcinoma is generally poor. The chance of survival could be improved if curative surgery were performed, but early diagnosis is then essential. Fine-needle aspiration cytology and endoscopic retrograde cholepancreaticography (ERCP) are widely used in order to obtain a precise diagnosis before laparotomy. In almost all patients with pancreatic adenocarcinomas, the oncogene Ki-ras is activated by point mutation. We describe a patient where conventional diagnostic procedures were inconclusive. However, DNA-analysis of aspirate from the pancreatic duct and from a pancreatic cyst showed activated Ki-ras oncogene. A malignant diagnosis was later confirmed. We propose that DNA-analyses of pancreatic fluid or tissues should be used whenever facing problems with an early and accurate diagnosis of pancreatic lesions.
