Abstract:

Objective The aim of this study was to investigate the potential clinical prognosis significance of progesterone receptor membrane component 1(PGRMC1) for breast cancer patients. Methods Fifty cases of breast cancer patients were derived from the Beijing Obstetrics and Gynecology hospital, Capital Medical University from Jan. 2008 to Dec 2014. Clinical and pathological data in details, such as date of primary diagnosis date, age, histologic grade, tumor size, lymph node metastasis, and patient follow-up information were collected and retrospectively analyzed. Immunohistochemical staining were carried out manually to evaluated the expression of estrogen receptor α(ERa)、progesterone receptor(PR)、Ki67 and PGRMC1 in breast cancer samples. Results For all the 50 tissues, the hormonal receptor status was 48.0% ERα positive(n=24), 42.0% PR positive(n=21), 4% Ki67 positive(n=2). Of the samples, 70.0%(n=35) were PGRMC1 positive. The result showed one statistically significant correlation, between PGRMC1 and tumor size, lymph node metastas(OR=1.60, 95%CI: 1.11-2.29; OR=1.12, 95%CI: 1.02-1.23). The association between conventional clinicopathological features and prognosis in breast cancer patients were evaluated. PGRMC1 expression would be used as predictors of recurrence(P=0.011) and poor overall survival(P=0.028) in breast cancer patients in Cox's proportional hazard model. Conclusion The high PGRMC1 level was associated with poor disease free survival rate and overall survival rate. PGRMC1 might be a independent prognostic factor breast cancer in the future.
