ABSTRACT
Objective To assess whether survival differed among patients who had triple-negative breast cancers compared with patients who had non-triple-negative breast cancers.Methods The clinicopathologic data of 684 patients with operable breast cancer,who were treated with multimodal therapy from December 1998 to June 2007 were analyzed.Of these patients,107 cases were confirmed to have triple-negative tumor histology(triple-negative group),577 cases were confirmed to have non-triple-negative tumor histology(non-triple-negative group).The 7 years cumulative survival and disease-free survival were analyzed by Kaplan-Meier method and compared by Log-rank test.The prognosis Was analyzed by COX regression model.Results The 7 years overall survival rates for triple-negative group and non-triple-negative group were 51.4%(55/107),74.2%(428/577),respectively,there Was significant difference between the two groups(P＜0.01).However,the 7 years overall survival rates of patients with triple-negative group and those who with Her-2 positive were 51.4%(55/107)and 53.1%(43/81)respectively,there Was no significant difference between them (P＞0.05).Univariate analysis revealed that the factors affecting the disease-free survival included age,menopausal status,tumor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status.Multivariate analysis showed minor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status were independent prognostic factors.Conclusions This study has shown a trend towards a poorer outcome for patients with triple-negative breast cancer similarity to patients with Her-2 positive cancers.Triple-negative breast cancer is an independent predictor factor of survival.
ABSTRACT
Objective To study the expression of LRP16 and E-cadherin(E-cad),ER,PR in eutopic endometrium and ectopic endometrium of endometriosis(EM),as well as to study the relation one another and the possible clinical significance.Methods The expression of LRP16 and E-cadherin,ER,PR in endometrium was detected by immunohistochemical two step staining methods in 72 patients with endometriosis which was finally confirmed by laparoscopic operation.Results The expression of LRP16 in epithelioglandular endochylema in eutopic endometrium of EM was significantly higher than that in ectopic endometrium(P
