在这项研究中,我们分析了p53在预测内脏转移性乳腺癌(VMBC)患者预后中的作用。对97例连续的VMBC患者进行了研究。P53蛋白阳性率为29.9%。在p53阴性组中,中位无瘤生存期(DFS)为25个月,中位无瘤生存期(DFS)为42.5个月,中位无瘤生存期(OS1)为13.5个月,中位无转移死亡时间(OS2)为13.5个月。P53阳性组分别为10个月、22个月和8个月。P53阴性亚型与P53阳性亚型的DFS和OS1差异有统计学意义。然而,P53似乎对OS2没有影响。COX回归分析显示,P53表达和TNM分期是DFS的预测因素。在多因素分析中,P53的表达和DFS的持续时间与OS1相关,而与OS2无关。综上所述,我们的数据表明,P53在VMBC的OS1中显示出预测作用,但对OS2没有预测作用。
In the study, we analyzed role of p53 in predicting outcome in visceral metastasis breast cancer (VMBC) patients. 97 consecutive VMBC patients were studied. P53 positivity rate was 29.9%. In the p53-negative group, median disease free survival (DFS) and time from primary breast cancer diagnosis to death (OS1), time from metastases to death (OS2) were 25, 42.5 and 13.5 months, respectively. In the p53-positive group, they were 10, 22 and 8 months, respectively. Statistically significant differences in DFS and OS1 were detected between the p53-negative and p53-positive subtypes. However, p53 appears to have no influence on OS2. In Cox regression analysis, p53 expression and TNM stage were predictive factors of DFS. In the multivariate analysis, p53 expression and the duration of DFS correlated with OS1, but not for OS2. Taken together, our data indicate p53 showing predicting role in OS1 for VMBC, but not for OS2.
