Incidence ofras oncogene activation in lung carcinomas in Hong Kong

Abstract

The incidence of Ki-ras codon 12 point mutational activation in Chinese patients with adenocarcinomas was 6 of 63 (9.5%). The incidence of Ki-ras 12 point mutational activation among men with lung adenocarcinomas in Hong Kong (6 of 32 patients, 18.8%) is significantly different from that in women in Hong Kong (0 of 31 patients, 0%). Although ras oncogenes are implicated as having a role in the development of lung adenocarcinomas, especially among smokers, it is clear from these data that they are not associated with the unusually high incidence of lung adenocarcinomas among women in Hong Kong.
