Background: Agent targeting HER-2 pathway plus chemotherapy has represented a major progress in the management of patients with breast cancer. However, the role of late-line treatment in heavily pretreated patients is still largely unclear. In the last decade, nab-paclitaxel has shown significant activity and good toxicity profile in metastatic breast cancer. Case Presentation: We report the case of a 76-year-old Caucasian woman with metastatic HER-2 positive ductal infiltrating breast carcinoma treated with a combination of weekly nab-paclitaxel and trastuzumab as fifth-line therapy. She had previously received first-line paclitaxel and trastuzumab, second-line vinorelbine and trastuzumab, third-line TDM1 and fourth-line oral capecitabine and lapatinib. Clinical and radiological staging showed progression at bone, skin and soft-tissue. The patient received weekly nab-paclitaxel plus trastuzumab. Massive objective response was clinically and PET documented which lasted 8 months. Tolerance to treatment was fairly good as well as cardiac safety. Conclusion: To the best of our knowledge, this is the first reported case of efficacy of nab-paclitaxel in combination with trastuzumab as fifth-line of treatment in a patient with metastatic HER-2 positive breast cancer. 展开更多

Breast cancer (BC) is the most common cancer in women and second only to lung cancer in terms of mortality. Among the three different BC subtypes, the oestrogen receptor positive represents nearly 70% of all cases and it is usually treated with anti-oestrogen drugs. However, the majority of hormone receptor positive metastatic BC patients develop resistance to anti-oestrogen treatments.The need for more down-stream therapies brought to the development of therapeutic strategies inhibiting the phosphatidylinositol 3-kinase-mammalian target of rapamycin (mTOR) pathway. Inhibitors of the mTOR have been tested in different clinical trials; everolimus has been Food and Drug Administration approved for the treatment of oestrogen receptor positive/human epidermal growth factor receptor 2 negative BC patients in combination with exemestane in patients who have progressed to anastrozole or letrozole after the encouraging results coming from BOLERO-2 trial. Similar results were obtained by the TAMRAD investigatory study testing tamoxifen in combination with everolimus in advanced BC. This editorial focuses on the results from BOLERO-2, BOLERO 4 and BOLERO-6, which tested the clinical importance of mTOR inhibition. We comment also on the role of phosphatidylinositol 3-kinase-mTOR inhibition as reported in the BELLE-2 and BELLE-3 trials and the future directions for the inhibition of this tumour metabolic axis. 展开更多

In this editorial,we comment on the article by Chen et al.We specifically focus on the risk factors,prognostic factors,and management of brain metastasis(BM)in breast cancer(BC).BC is the second most common cancer to have BM after lung cancer.Independent risk factors for BM in BC are:HER-2 positive BC,triplenegative BC,and germline BRCA mutation.Other factors associated with BM are lung metastasis,age less than 40 years,and African and American ancestry.Even though risk factors associated with BM in BC are elucidated,there is a lack of data on predictive models for BM in BC.Few studies have been made to formulate predictive models or nomograms to address this issue,where age,grade of tumor,HER-2 receptor status,and number of metastatic sites(1 vs>1)were predictive of BM in metastatic BC.However,none have been used in clinical practice.National Comprehensive Cancer Network recommends screening of BM in advanced BC only when the patient is symptomatic or suspicious of central nervous system symptoms;routine screening for BM in BC is not recommended in the guidelines.BM decreases the quality of life and will have a significant psychological impact.Further studies are required for designing validated nomograms or predictive models for BM in BC;these models can be used in the future to develop treatment approaches to prevent BM,which improves the quality of life and overall survival. 展开更多

Overexpression and activation of HER-2/neu (also known as c-erbB-2), a proto-oncogene, was found in about 30% of human breast cancers, promoting cancer growth and making cancer cells resistant to chemo- and radio-therapy. Wild-type p53 is crucial in regulating cell growth and apoptosis and is found to be mutated or deleted in 60-70% of human cancers. And some cancers with a wild-type p53 do not have normal p53 function, suggesting that it is implicated in a complex process regulated by many factors. In the present study, we showed that the overexpression of HER-2/neu could decrease the amount of wild-type p53 protein via activating PI3K pathway, as well as inducing MDM2 nuclear translocation in MCF7 human breast cancer cells. Blockage of PI3K pathway with its specific inhibitor LY294002 caused Gl-S phase arrest, decreased cell growth rate and increased chemo- and radio-therapeutic sensitivity in MCF7 cells expressing wild-type p53. However, it did not increase the sensitivity to adriamycin in MDA-MB-453 breast cancer cells containing mutant p53. Our study indicates that blocking PI3K pathway activation mediated by HER-2/neu overexpression may be useful in the treatment of breast tumors with HER-2/neu overexpression and wild-type p53. 展开更多

To detect serum HER-2 oncoprotein levels in patients with operable and metastatic breast cancers, and to study the correlations between serum HER-2 level and lymph node status as well as other clinical parameters. Methods A total of 120 women were studied consisting of 10 healthy volunteers, 31 benign breast disease, 53 operable breast cancer, and 26 metastatic breast cancer patients. The levels of serum HER-2 were measured using an enzyme-liked im-munosorbent assay (ELISA). Results The mean serum HER-2 levels were 9.6 ± 1.5 ng/mL in healthy volunteers, 11.9 ± 1.6 ng/mL in benign breast disease, 13.2 ± 4.2 ng/mL in operable breast cancer, and 30.5 ± 30.8 ng/mL in metastatic breast cancer patients. The former is much lower than the latter three (P = 0.02, 0.001, 0.03, respectively). If using 15 ng/mL as a normal baseline, elevated serum HER-2 levels were observed in none of the healthy volunteers as well as patients with benign disease, but in 18.9% (10/53) operable breast cancer patients and 61.5% (16/26) metastatic patients. In patients with operable breast cancer, there was a positive correlation between serum concentrations of HER-2 and the size of primary tumor (P < 0.05), whereas there was no correlation between serum concentration and axillary lymph node or estrogen receptor status. In patients with metastatic dise-ase, there was no correlation with site of metastases (P > 0.05). Conclusion Serum HER-2 level was strongly correlated with tumor loads and clinical stages, thus acting as a promising predictor of cancer recurrence in breast cancer patients. 展开更多

Objective: our previous studies have demonstrated that HER-2/neu gene expression in human breast cancer MCF-7 cells promotes angiogenesis in MCF-7 cells xenograft tumors, and genistein inhibits angiogenesis in MCF-7 cells with HER-2/neu expression xenograft tumors. Here, the effects of genistein on the expression of vascular endothelial growth factor (VEGF) in MCR-7 cells with HER-2/neu expression were further studied for exploring the molecular mechanism of anti-angiogenesis in HER-2/neu-overexpressing breast cancer by genistein. Methods: HER-2/neu-overexpressing MCF-7 cells (MCF-7/HER-2) were established by transfecting HEg-2/neu gene into HER-2/neu negative expression breast cancer MCF-7 cells. Immunocytochemical staining, western blot and reverse transcription-polymerase chain reaction (RT-PCR) were adopted to measure the expression of VEGF in MCF-7/HER-2 cells treated by genistein for 24, 48 and 72h. Results: HER-2/neu expression up-regulated VEGF mRNA and protein in MCF-7 cells, genistein decreased VEGF mRNA and protein level in MCF-7/HER-2 cells in a time-dependent manner. Conclusion: These results suggest that VEGF plays an important role in HER-2/neu gene expression promoted antiogenesis in breast cancer and genistein induced down-regulation of the expression of VEGF may be one of the molecular mechanisms of its anti-angiogenesis in HER-2/neu-overexpressing breast cancer. 展开更多

The accurate assessment ofa proto-oncogene, human epidermal growth factor receptor-2 gene (HER-2), is extremely important for the therapy and prognosis of breast cancer. Currently, immunohistochemistry (IHC) is the method widely used for the detection of HER-2 protein. Fluorescence in situ hybridization (FISH) has been suggested to be a golden standard assay for HER-2 amplification. This study examined the expression and amplification of HER-2 in paraffin-embedded sections of breast cancer tissues, and compared the two methods on the measurement of HER-2 status. HER-2 gene and protein were determined in breast cancer samples from 52 Chinese women by FISH and IHC respectively. The findings indicated that the HER-2 gene amplification was found in 18 cases (34.6%) by FISH and the HER-2 protein over-expression (score 3+) in 15 cases (28.8%) by IHC. hnmunohistochemically, 28.6% of the cases scored as 2+ and 93.3% of the cases scored as 3+ were HER-2-positive by FISH. There was a significant correlation between the HER-2 gene amplification and HER-2 protein over-expression in breast cancer (P〈0.005). No correlation was noted between the HER-2 gene amplification and any of the clinicopathological parameters examined, including age, menopausal status, menarche age, tumor size, histological tumor type, histological grade, lymph node status, and the expression of ER and PR. It was concluded that the detection of HER-2 gene amplification in breast cancer by FISH is valuable and can compare with HER-2 protein detection by IHC. 展开更多
