[An application value of detecting K-ras and p53 gene mutation in the stool and pure pancreatic juice for diagnosis of early pancreatic cancer].
Zhonghua Yi Xue Za Zhi 2001; 81(17):1050-3ZY

Abstract

OBJECTIVE

To explore new methods for the early diagnosis of pancreatic cancer through detecting of K-ras, p53 mutations in pancreatic juice and stool.

METHODS

201 patients in PUMC Hospital from 1994-2000. 5 and 60-control individuals were enrolled. K-ras point mutations were detected by PCR-RFLP, however p53 mutation was detected by PCR-SSCP.

RESULTS

K-ras mutations in pancreatic juice were found in 87.8% (36/41) of pancreatic cancer, 23.5% (4/17) of benign pancreatic disease. Of 261 stools specimens, amplification was successful in 235 (90.0%). K-ras mutation in stool were found in 88.0% (66/75) of pancreatic cancer 51.1% (24/47) of benign pancreatic disease, 19.6% (9/46) of normal individuals. p53 mutation in pancreatic juice were found in 47.4% (18/38), 12.5% (2/16) of benign pancreatic disease, p53 mutation in stool were found in 37.1% (23/62), 19.1% (4/12) of chronic pancreatitis.

CONCLUSION

K-ras mutation in pancreatic juice has high sensitivity and specificity, so it can be used as a adjunct in the diagnosis of pancreatic cancer. Detection of K-ras mutation combined with p53 mutation in stool can be helpful to screen for pancreatic carcinoma. Combined with serum CA19-9 detection, it might increase the early diagnostic rate of pancreatic carcinoma.
