Pancreatic adenocarcinoma has a very poor prognosis resulting in part from the frequency
of micrometastases not detectable by conventional imaging at the time of diagnosis
or treatment. The activation of the K-ras oncogene by the point mutation at codon 12, found in more than 75% of cases of advanced
ductal adenocarcinoma of the pancreas, has been used by Hayashi et al
1
to detect micrometastases in lymph nodes histologically negative for metastasis.
We here report a patient with pancreatic adenocarcinoma exhibiting a solitary liver
metastasis macroscopically in whom K-ras gene mutation was also detected in other portions of the liver that were thought
to be free of cancer.To read this article in full you will need to make a payment
