First, we found that the overall prevalence of mutations within codons 12 and 13 of the K-ras gene was 25% in the nonrecurring group vs. 71% in the patients with recurrent disease (P < 0.0001) and, second, that mutations other than GGT to GAT occurred, with one exception, exclusively in recurring tumors.
