Clinicopathological Features and Prognosis of Metaplastic Breast Carcinoma: Experience of a Major Chinese Cancer Center

Metaplastic breast carcinoma (MBC) is a rare heterogeneous group of primary breast malignancies, with low hormone receptor expression and poor outcomes. To date, no prognostic markers for this tumor have been validated. The current study was undertaken to evaluate the clinicopathologic characteristics, the response to various therapeutic regimens and the prognosis of MBCs in a large cohort of patients from Tianjin Medical University Cancer Hospital in China. Ninety cases of MBCs diagnosed in our hospital between January 2000 and September 2014 were retrieved from the archives. In general, MBCs presented with larger size, a lower rate of lymph node metastasis, and demonstrated more frequent local recurrence/distant metastasis than 1,090 stage-matched cases of invasive carcinoma of no specific type (IDC-NST), independent of the status of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 expressions. The five-year disease-free survival (DFS) of MBC was significantly worse than IDC-NST. Using univariate analysis, lymph node metastasis, advanced clinical stage at diagnosis, high tumor proliferation rate assessed by Ki-67 labeling, and epidermal growth factor receptor (EGFR) overexpression/gene amplification were associated significantly with reduced DFS, while decreased OS was associated significantly with lymph node metastasis and EGFR overexpression/gene amplification. With multivariate analysis, lymph node status was an independent predictor for DFS, and lymph node status and EGFR overexpression/gene amplification were independent predictors for OS. Histologic subtyping and molecular subgrouping of MBCs were not significant factors in prognosis. We also found that MBCs were insensitive to neoadjuvant chemotherapy, routine chemotherapy, and radiation therapy. This study indicates that MBC is an aggressive type of breast cancer with poor prognosis, and that identification and optimization of an effective comprehensive therapeutic regimen is needed.     

SYK expression in human breast cancer

BACKGROUND: Syk (Splenic Tyrosine Kinase) is an intracellular receptor protein kinase involved in cell proliferation, differentiation and phagocytosis. It has been studied in T and B lymphocytes, NK cells and platelets. The strong expression of Syk in mammary gland prompted research into its potential role in mammary carcinogenesis. There have been very few studies about its role in breast cancer with conflicting results. This study aims to investigate the hypothesis that Syk expression is down-regulated in breast cancer compared with ANCT and the association between its expression and clinicopathological parameters. MATERIALS AND METHODS: mRNA was extracted from 48 breast cancer specimens. Relative Syk to ribosomal RNA expression was determined by RT-PCR and Taqman methodology. Mann-Whitney U test was used to examine the association between Syk expression in cancer and ANCT. Spearman's rank correlation test was used to examine the association between Syk expression in tumours and patients' age, tumour size, tumour grade, estrogen and progesterone receptor status, lymph node metastasis, vascular invasion and clinical outcome. RESULTS: The median for the relative value of Syk expression was 0.17 and 0.18 (range: 0.12 - 0.56 and 0.0 - 1.77) for tumours and ANCT respectively. There was no significant association between Syk expression in cancers and ANCT (p= 0.598) nor between Syk expression in tumours and patients' age, tumour size, tumour grade, estrogen and progesterone receptor status, lymph node metastasis, vascular invasion or prognosis. CONCLUSION: This study shows that Syk mRNA expression does not seem to vary between breast tumours and ANCT. Furthermore, we observed no significant association between Syk expression and clinicopathological parameters.     

妊娠哺乳期乳腺癌患者的预后情况及其影响因素分析

目的:分析妊娠哺乳期乳腺癌患者的预后情况及其影响因素。方法:将2010年1月至2012年12月期间贵州省贵阳市妇幼保健院、贵州省医科大学和贵州省肿瘤医院收治的妊娠哺乳期乳腺癌患者60例作为研究组,选择同期收治的非妊娠哺乳期乳腺癌患者60例作为对照组,比较两组5年生存率和临床病理特征,并应用单因素和多因素Logistic回归分析患者预后的影响因素。结果:研究组5年生存率为61.67%(37/60),5年无病生存率为46.67%(28/60),均低于对照组的81.67%(49/60),73.33%(44/60)(P0.05)。研究组肿瘤最大直径、腋淋巴结转移率、TNM分期为III期的比例、雌激素受体阳性率、Ki67细胞阳性率≥20%的比例均高于对照组(P0.05),两组孕激素受体阳性率比较无统计学差异(P0.05)。单因素分析显示妊娠哺乳期乳腺癌患者总生存期与肿瘤最大直径、TNM分期、Ki67细胞阳性率≥20%的比例、腋淋巴结转移率有关(P0.05)。多因素Logistic回归分析显示,TNM分期为III期、Ki67细胞阳性率≥20%、腋淋巴结转移是影响妊娠哺乳期乳腺癌患者预后的独立危险因素(P0.05)。结论:妊娠哺乳期乳腺癌患者的预后较差,TNM分期为III期、Ki67细胞阳性率≥20%、腋淋巴结转移是影响患者预后的危险因素,对于临床防治具有重要的启示作用。     

术前CA125、OPN、CXCL8、NLR联合检测对乳腺癌改良根治术患者术后复发转移风险的评估价值

摘要 目的：探讨术前糖类抗原125（CA125）、骨桥蛋白（OPN）、趋化因子配体8（CXCL8）、中性粒细胞与淋巴细胞比值（NLR）联合检测对乳腺癌改良根治术患者术后复发转移风险的评估价值。方法：选取2015年4月-2016年4月期间我院收治的乳腺癌改良根治术患者384例按照术后有无复发转移分为未复发转移组（n=345）和复发转移组（n=39）,对比复发转移组、未复发转移组CA125、OPN、CXCL8、NLR,乳腺癌改良根治术患者术后复发转移的影响因素采用多因素Logistic回归分析。采用受试者工作特征（ROC）曲线来判断CA125、OPN、CXCL8、NLR检测对乳腺癌改良根治术患者术后复发转移风险的评估价值。结果：复发转移组的CA125、OPN、CXCL8、NLR高于未复发转移组,组间对比差异有统计学意义（P<0.05）。乳腺癌改良根治术患者术后复发转移与肿瘤最大直径、临床分期、术前新辅助化疗、人表皮生长因子受体2（HER2）、淋巴结转移、组织学类型、细胞增殖标志抗原（ki-67）、雌激素受体（ER）/孕激素受体（PR）、P53、术后放疗、术后内分泌治疗有关（P<0.05）。多因素Logistic回归分析结果显示：OPN偏高、CXCL8偏高、NLR偏高、肿瘤最大直径≥2 cm、淋巴结转移阳性、ER/PR双阴性、临床分期为III期、术前未接受新辅助化疗是乳腺癌改良根治术患者术后复发转移的危险因素（P<0.05）。术前CA125、OPN、CXCL8、NLR联合检测评估复发转移的曲线下面积（AUC）为0.855均高于各指标单独检测。结论：乳腺癌改良根治术后复发转移与OPN、CXCL8、NLR、肿瘤最大直径、淋巴结转移、ER/PR、临床分期、术前接受新辅助化疗均存在一定联系,临床需据此采取针对性干预措施加以防范。且术前CA125、OPN、CXCL8、NLR联合检测辅助评估术后复发转移的价值较高。     

Lack of relationship between the expression of hsp27 heat shock estrogen receptor-associated protein and estrogen receptor or progesterone receptor status in male breast carcinoma

Estrogen, through estrogen receptors (ERs), may regulate the synthesis of progesterone receptors (PRs) and of a heat shock estrogen receptor-associated protein (hsp27). In female breast carcinoma (FBC) both proteins serve as surrogate indicators for the presence of functional ERs. In addition, the expression of these proteins was related to other prognostic indicators of value in female breast tumours. Endocrine disorders, hormone therapy and altered estrogen metabolism have been associated with the development of male breast cancer (MBC), suggesting that evaluation of the expression of ER, PR and hsp27 might improve our understanding of the biology of this tumour. ER and PR status and hsp27 expression were evaluated by immunohistochemistry in 16 primary MBC patients. The interrelationships between these parameters were established and compared with the clinicopathological data on the tumours. Ten (56%) MBC patients were ER-positive, 69% were PR-positive and all samples were hsp27-positive. Our series of MBC patients showed a positive correlation between ERs and PRs, however there was a lack of correlation between hsp27 and ERs or PRs. MBCs did not exhibit any correlation between the biomarkers studied and known prognostic indicators for females (e.g. Scarff-Bloom-Richardson (SBR) or modified SBR (MSBR) grade, T stage, lymph node status). This is the first published series reporting the incidence of hsp27 in MBC. The lack of association between the expression of ERs and hsp27 found in MBC differs from the results reported for FBC, moreover the expression of ERs, PRs or hsp27 did not correlate with the clinicopathological parameters that have prognostic value in females. Although the data were obtained from a relatively small sample population, our findings suggest that MBC and FBC are biologically different tumours with respect to the expression of the studied proteins.     

Lisinopril attenuates renal oxidative injury in l-NAME-induced hypertensive rats

Genetic factors related to cancer have been extensively studied and several polymorphisms have been associated to breast cancer. The FGFR4, MTHFR, and HFE genes have been associated with neoplastic diseases development. The current report outlines the analysis of the polymorphisms G388A (FGFR4), C677T (MTHFR), C282Y, and H63D (HFE) in Brazilian breast cancer patients. We studied 68 patients with invasive ductal and operable breast carcinoma and 85 women as a control group. The polymorphism frequencies in the breast cancer and control groups were analyzed, but no significant difference was observed by comparing the two groups. The presence of each polymorphism was analyzed according to the clinical features and markers already established as prognostic in the breast cancer group. The C677T, H63D, and G388A polymorphisms were not associated to histological grade, age of diagnosis, expression of HER2 receptor, or estrogen and progesterone receptor. The H63D polymorphism showed a significant association (P = 0.02) with the presence of p53 mutations, and C667T showed association to lymph node involvement (P = 0.05). Lymph node involvement, G388A polymorphism, and histological grade were independently associated to metastasis/death. Our data suggests that the polymorphisms G388A, C677T, and H63D are not useful in breast cancer diagnosis, but they may be significant additional prognostic markers related to breast cancer survival.
