Abstract
-
In this study of 64 cases of breast cancer with a clinical follow-up period of more than
5 years, several prognostic factors were evaluated. The purpose of this study was to
determine whether any one parameter or group of parameters serves as adequate
predictors of tumor behavior and patient's prognosis. Several prognostic factors included
clinicopathological variables (patient's age, histologic grade, status of lymph node (LN)
metastasis, and tumor size), expression of estrogen receptor (ER), progesterone receptor
(PR), p53, bcl-2 and CD44 by immunohistochemistry, and DNA ploidy pattern. The
results
showed that the expression of ER and PR had a significant inverse correlation
with the histologic grade (ER, p=0.05; PR, p<0.05). The expression of p53 protein
showed a significant relationship with high histologic grade of tumor (p<0.05). The
expression of bcl-2 protein was preferably seen in low histologic grade of tumor
(p<0.05) and significantly associated with ER positive or PR positive tumors (ER,
p<0.05; PR, p<0.05). This results suggest that bcl-2 protein might play significant
roles in ER and PR. The CD44 expression showed a significant relationship with tumor
size (p<0.05). The large size and aneuploidy pattern of tumor had a tendency to be
associated with shorter patient survival. Cox's multivariate analysis showed that overall
survival was affected by LN metastasis because of the shorter survival in patients with
LN metastasis. In conclusion, tumor size, DNA ploidy pattern, and LN metastasis were
themselves significant predictors of breast cancer survival rate.
