Purpose : We investigated the prognostic impacts of p53, c-erbB-2, nm23 and Ki-67
expression in patients with stage ¥± and ¥²A gastric carcinoma who underwent curative
(R0) resections.
Materials and Methods : 261 paraffin-embedded gastric carcinoma tissues (stage ¥±,
121 ; stage ¥²A, 135) were stained with the monoclonal antibodies, p53, c-erbB-2, nm23
and Ki-67 using the labelled streptovidin biotin method. The positivity was determined
by two pathologists who were kept blind for the patients' outcome.
Results : The overexpression was seen in 51.7% for p53, 11.9% for c-erbB-2, and
70.1% for nm23. The mean Ki-67 labelling index was 25.5¡¾16.7. The rates of
overexpression between the stage ¥± and stage ¥²A were not significantly different in
all these molecules. Overexpression of p53 was more likely to be associated with old
age and lymph node metastasis. Overexpression of c-erbB-2 was more likely to be
associated with Borrmann type ¥°, ¥± and well-differentiated tumor However, nm23 was
more frequently expressed in patients with older age and well-differentiated tumor. In
survival analysis, the overexpressions of p53 and Ki-67 were significantly associated
with poor prognosis of the patients (p<0.01), but c-erbB-2 and nm23 were not related
to the patients' outcome. In a multivariate analysis of prognostic factors, only the lymph
node metastasis was an independent prognostic factor.
Conclusion : Although the values did not reach statistical significance in a multivariate
analysis, the overexpression of p53 and Ki-67 tended to have adverse effects on the
prognosis of patients with gastric cancer.
