Ciliated gastric cells among Japanese living in Hawaii.

A total of 129 consecutive gastrectomy specimens from Japanese (99), Philippinos (11), Hawaiians (8), Koreans (5), Chinese (4) and Caucasians born in Hawaii (2) were examined under high-power light microscopy (1000 x) for the presence of ciliated gastric cells. Fifty-two of the 129 gastrectomy specimens (40.3%) contained ciliated cells. Ciliated cells were found in the basal segments of antral glands (usually cystically dilated) whose superficial segments had undergone intestinal metaplasia. The presence of ciliated cells in the gastric mucosa was influenced by the age of the patient and by the degree of intestinal metaplasia: the older the patient, the greater the degree of intestinal metaplasia and the greater the frequency of specimens with ciliated cells. The presence of ciliated cells was also influenced by the type of lesion in the specimen. Although the highest frequency (47.2%) was found in stomachs removed for adenocarcinoma, a substantial number of stomachs removed for gastric ulcer also showed that change (36%). The data suggest that increasing age and advanced atrophic gastritis, especially of the antrum, provide the necessary conditions that lead to the development of cilia, not only in Japanese subjects, but in other Hawaiian ethnic groups as well.
