[Expression of cycline-dependent kinase p27 in the low differentiated gastric adenocarcinoma].
The authors investigated p27 expression in 21 cases of high-grade gastric adenocarcinoma with portions of signet ring cell differentiation, by comparing that in 11 cases of chronic atrophic gastritis with Helicobacter pylori and in 5 cases of the intact gastric mucosa. The mean age of patients with gastric adenocarcinoma was 67.7 years (35-86 years); there were 9 males and 12 females. All tumors were of T3 N1-2 M0 stage. Helicobacter pylori was found in 3 of the 21 patients. The investigations indicated a great difference (by 2.4-7.6 times) and a statistically significant decrease in p27 expression in the adenocarcinoma cells as compared to the comparison groups. However, there was no significant correlation between the lower level of p27 expression and the prognosis in patients with adenocarcinoma.
