原癌基因gankyrin在乳腺浸润性导管癌中的表达研究

目的 探讨gankyrin在乳腺浸润性导管癌中的表达水平及其在乳腺癌发生发展中的作用机制。方法 采用蛋白免疫印记的方法 检测28例乳腺浸润性导管癌的癌与癌旁组织中gankyrin的表达水平；采用经典的分子克隆技术构建gankyrin的真核表达质粒；利用双报告基因技术检测p53活性的变化；利用蛋白免疫印记技术检测p53、p21和Bax的蛋白水平。结果 gankyrin在28例乳腺浸润性导管癌癌组织的表达明显高于癌旁组织，在MCF-7细胞中，过表达的gankyrin明显抑制了p53的转录活性，使p53、p21和Bax的蛋白水平最著降低。结论 gankyrin对p53的负调控在乳腺浸润性导管癌的发生过程中起重要作用。

Outcomes of breast-conservation therapy for invasive lobular carcinoma are equivalent to those for invasive ductal carcinoma

BACKGROUND: Breast-conservation therapy (BCT), including wide local excision and postoperative irradiation, is considered standard treatment for early-stage invasive ductal carcinoma (IDC). The use of BCT in patients with invasive lobular carcinoma (ILC) has been questioned because of concerns regarding ipsilateral breast recurrence and risk of bilateral breast cancer. We evaluated our institutional experience with BCT and compared treatment outcomes for ILC with those for IDC. METHODS: A review of our BCT database revealed 84 patients with ILC and 1,126 with IDC with stage I or II disease treated with BCT and radiation between 1976 and 1999. We evaluated local-regional recurrence, disease-specific survival, and contralateral breast cancer rates in both groups. RESULTS: The 5- and 10-year local-regional recurrence rates for the ILC group were 1% and 7%, respectively, and 4% and 9%, respectively, for the IDC group (P = .70). There were no significant differences in the 5- and 10-year disease-specific survival rates between the groups. Contralateral breast cancer occurred in 11.3% of patients with IDC and 11.9% of patients with ILC. CONCLUSIONS: BCT achieves similar local-regional control and survival outcomes in selected patients with ILC or IDC. Breast-conservation therapy is an appropriate treatment strategy for patients with early-stage invasive lobular carcinoma.

Prognosis of invasive micropapillary carcinoma compared with invasive ductal carcinoma in breast: A meta-analysis of PSM studies

BackgroundInvasive micropapillary carcinoma (IMPC) is a rare histological subtype of breast cancer. The outcome of IMPC remains controversial; we conducted a meta-analysis of propensity score matching (PSM) studies to evaluate the prognostic difference between IMPC and invasive ductal carcinoma (IDC).MethodsWe searched PubMed, EMBASE and the Cochrane library for PSM studies comparing survival data between IMPC and IDC. The summarized odds ratios (ORs) and 95% confidence interval (95% CI) are calculated by STATA software utilizing fixed-effect or random-effect models, depending on the heterogeneity of the eligible studies.ResultsEight PSM studies including 2102 IMPC patients are included in the meta-analysis. Compared with IDC, IMPC has a similar overall survival (OS) (estimated OR = 0.87, 95% CI: 0.61–1.25), but a shorter relapse free survival (RFS) (estimated OR = 1.31, 95% CI: 1.06–1.61); the shorter RFS might owe to the significantly higher loco-regional recurrence rate of IMPC (estimated OR = 3.60, 95% CI: 1.99–6.52). Funnel plots and Egger’s tests are used to evaluate publication bias and the p value for OS and RFS are 0.036 and 0.564 respectively.ConclusionsOur results demonstrate that compared with IDC, IMPC exhibits a similar, even favorite OS, but a shorter RFS; and the shorter RFS might owe to the significantly higher loco-regional recurrence rate of IMPC. These results could contribute to the individualized therapy and follow-up strategies for IMPC patients.     

Invasive ductal breast carcinoma with predominant intraductal component: Clinicopathological features and prognosis

PurposeInvasive ductal carcinoma with predominant intraductal component (IDCPIC) represents almost 5% of breast cancers. Nevertheless few data exist concerning their characteristics and prognostic behaviour. Our objective was to describe IDCPIC's clinicopathological and prognostic features and compare them to that of invasive ductal carcinoma without predominant intraductal component (IDC).MethodsRetrospective single centre study including all the localized invasive ductal carcinoma listed in our institutional database. Clinical, radiological and pathological criteria were collected as well as disease-free survival (DFS) data.ResultsFrom 1995 to 2008, 4109 invasive ductal breast cancers treated were included. Out of them 192 (4.7%) were IDCPIC. Most of IDCPIC (63%) were discovered by radiological screening whereas IDC suspicion was more often clinical (82.7% vs 49.5%, p < 0.001). Pathological lymph node involvement was less frequent in IDCPIC (35.8 vs 44.3%, p = 0.04). Invasive tumour median size was 2-fold smaller in IDCPIC (10 mm vs 20 mm, p<0.001). Hormone receptors expression was similar between both groups whereas HER2 overexpression was more frequent in IDCPIC (32% vs 14.3%, p<0.001). Mastectomy was more frequently performed for IDCPIC (67.7% vs 30.3%, p < 0.001) whereas chemotherapy and radiation therapy were less frequent (55.5% vs 68%, and 82.8% vs 95.5%, respectively, p < 0.001 for both). After matching for discriminant clinicopathological features (tumour size, lymph node involvement, vascular invasion, HER2), DFS was similar in both groups (5-year DFS of 87.4% vs 84.4%, p = 0.47).ConclusionIDCPIC and other IDC with invasive components showing similar clinicopathological features display a similar prognosis.     

乳腺浸润性导管癌SLeX和BRCA1表达研究

目的探讨唾液酸路易斯X抗原（SLeX）和乳腺癌1号基因（BRCA1）表达与乳腺浸润性导管癌（BIDC）临床病理指标及预后的关系。 方法收集2014年5月至2015年12月手术切除的BIDC标本80例及距癌灶3 cm的癌旁乳腺组织30例,应用EliVision^TM plus免疫组织化学2步法检测SLeX和BRCA1在癌组织及癌旁乳腺组织中的表达。运用SPSS 22.0软件分析,SLeX和BRCA1阳性率、临床病理指标等计数资料用例（%）表示,组间比较进行χ²检验及相关性分析,P<0.05为差异有统计学意义。 结果癌组织SLeX和BRCA1阳性率分别为86.3%（69/80）、60.0%（48/80）,癌旁乳腺组织分别为20.0%（6/30）和100%（30/30）,差异均有统计学意义（P<0.05）。SLeX在TNM分期（T3+T4）、低分化、有淋巴结宏转移和随访5年间有复发转移患者中高表达;BRCA1在年龄>53岁、TNM分期（T3+T4）、低分化、有淋巴结宏转移和随访5年间有复发转移患者中低表达。 结论SLeX和BRCA1与BIDC的发生发展显著相关,前者表达上调和（或）后者表达下调均预示癌组织分化差、进展快、预后不良。     

Adequacy of diagnostic tests and surgical management of symptomatic invasive lobular carcinoma of the breast

Introduction

Invasive lobular carcinoma (ILC) presents diagnostic and therapeutic challenges as it produces subtle radiological changes. It has been suggested that it is not suitable for breast conserving surgery (BCS). The aim of this study was to ascertain the diagnostic adequacy of modern mammography and ultrasonography in the context of a fast track symptomatic diagnostic clinic in the UK. It also sought to compare the mastectomy, re-excision and BCS rates for ILC with those for invasive ductal carcinoma (IDC).

Methods

A retrospective analysis of prospectively collected data was carried out on all new symptomatic cancers presenting to the one-stop diagnostic clinic of a single breast unit between 1998 and 2007.

Results

Compared with IDC, ILC was significantly larger at presentation (46mm vs 25mm), needed re-excision after BCS more often (38.8% vs 22.3%) and required mastectomy more frequently (58.8% vs 40.8%). Although mammography performs poorly in diagnosing ILC compared with IDC, when combined with ultrasonography, sensitivity of the combined imaging was not significantly different between these two histological types.

Conclusions

Provided ultrasonography is performed, standard radiological imaging is adequate for initial diagnosis of symptomatically presenting ILC but some additional preoperative workup should clearly be employed to reduce the higher number of reoperations for this histological type.     

Accompanying DCIS in breast cancer patients with invasive ductal carcinoma is predictive of improved local recurrence-free survival

BackgroundDuctal carcinoma in situ (DCIS) often accompanies invasive ductal carcinoma (IDC). The presence of co-existing DCIS is postulated to present as a less aggressive phenotype than IDC alone.Patients and methodsPatients diagnosed with hormone receptor-positive breast cancer receiving mastectomy were evaluated. Only patients without adjuvant radio- and chemotherapy were included to decrease treatment bias on local recurrence (LR).ResultsOf 2239 breast cancer patients, 198 fulfilled the inclusion criteria. The overall LR rate was 11.6%. Tumor stage (p = 0.002), nodal status (pN2 vs. pN0, p = 0.023) and pure IDC compared with IDC-DCIS (p = 0.029) were multivariate independent factors for increased LR risk. Patients with IDC-DCIS were significantly younger (p < 0.001), had smaller tumors (p = 0.001), less lymph node involvement (p = 0.012). The LR rate was significantly increased in patients with pure IDC (p = 0.012). The time to distant metastases was decreased in patients with pure IDC compared with that observed in patients with IDC-DCIS (log rank = 0.030).ConclusionInvasive ductal carcinoma accompanied by DCIS is associated with lower LR. The prognostic value of co-existing DCIS in the adjuvant decision-making process may be considered a new independent prognostic marker. This finding needs further studies to evaluate its usefulness in premenopausal women.
