1071 Background: Metronomic chemotherapy regimens have shown efficacy in patients with metastatic breast cancer by antiangiogenic mechanisms. When used metronomically the toxicity profile of capecitabine is low. Triple negative breast cancer is a common problem in India and developing countries. Approximately 30% of triple negative breast cancer express EGFR and its mutation. Methods: Since October 2003 to December 2011 we objectively tested response rates, clinical benefit, and safety of gefitinib and capecitabine administered with a metronomic schedule of 500 mg thrice daily in heavily pretreated metastatic breast cancer patients with gefitinib 250 mg once daily. 300 patients were screened for EGFR expression. Among 85 enrolled patients with EGFR positivity, 76 were evaluable. ECOG performance status (PS) was 0-2, median age 52 years (range 36-65), bone plus visceral metastasis in 40% of patients. Rest had only visceral metastasis. All the patients were pretreated with anthracyclines and taxanes. The combination was administered for a median duration of 32 weeks (range 12-166). Results: We observed 18 partial responses (PR: 24%), 42 (55%) stable disease (SD). Median time to progression was 53 weeks, (95% CI, range 12-166 weeks). Safety of metronomic capecitabine with gefitinib was excellent. Neither grade 2-4 haematological or clinical side effects were recorded. Only 12 patients experienced grade I (WHO) hand-foot syndrome. Conclusions: Treatment with metronomic capecitabine and gefitinib was effective and minimally toxic in heavily pretreated breast cancer patients.

Background Reports on the incidence and prognoses of lung metastases when diagnosing breast cancer patients with different subtypes are limited. Our study investigated the effect of molecular sub-typing stratification on the prognoses of lung metastatic breast caner patients. Methods Patients with breast cancer and lung metastases were identified from Surveillance, Epidemiology and End Results population-based data between 2010 and 2015. Univariate and multivariate Cox regression analyses were performed to identify risk factors and prognoses, overall survival (OS) and breast cancer-specific survival for patients with breast cancer lung metastases. Results We identified 6,516 patients with lung metastatic breast cancer, representing 1.7% of the entire cohort and 30.4% of the subset with metastatic disease. This included 2,940 hormone receptor (HR)+/HER2− patients, 852 HR+/HER2+ patients, 547 HR−/HER2+ patients and 983 triple-negative patients. The median OS for all lung metastatic patients was 13 months. Multivariate analysis revealed that those lung metastatic breast cancer patients of older age (>80), black race, with poorly differentiated tumors, carcinoma histology, triple-negative subtype, more metastatic sites and no surgery, and no chemotherapy showed significantly poor survival, both overall and breast cancer-specific. Conclusions Our findings show that molecular sub-type and more metastatic sites might have significant influence on the incidence and prognosis of breast cancer lung metastases. We also identified several prognostic factors that could guide therapy selection in the treatment of lung metastatic patients.

Abstract Background Breast cancer is the most common malignant tumor among females around the world. It represents 1.7 million new cases per year and 25% of all types of cancers. Objectives Assessment of median overall survival in most aggressive subtypes of metastatic breast cancer (Triple –Ve and HER2+Ve) & to compare survival of metastatic HER2+Ve breast cancer in group received targeted versus that did not receive. Patient and Methods Multi institutional retrospective study for assessment of median OS in metastatic breast cancer for themost aggressive subtypes (HER2+Ve &Triple-Ve) at Ain Shams University Hospitals and El-Matarya teaching Hospital. Results Seventy-three metastatic breast cancer patients were included (31 Triple-Ve & 42 HER2+Ve) in the period between January 2014 and December 2016 At Ain Shams University Hospitals and El-Matarya teaching Hospital, we found that median OS for Triple negative group is 16 months with (95% CI 8.8- 23.6) , that for HER2+Ve group is 17 months with (95% CI 13.9 – 20.6) & for patients did not receive targeted therapy, median OS is 10 months (95% CI. 4-19.4,P.000). Conclusion From our study,we highlight that metastatic breast cancer patients (HER2+Ve subtype) &received targeted therapy, had the most superior survival outcome. so,targeted therapy must be included in first line treatment.

Background. Breast tumors are composed of phenotypically diverse groups of cells; however, it is unclear which of these cells contribute to tumor development. Breast cancer management usually targets proliferating cells, but as breast cancer stem cells are slowly cycling, they may escape these targets whenever they are not actively proliferating. This may explain the occurrence of recurrences and failure of the treatment. Aim. To assess the impact of the BCSC expression on progression-free survival (PFS), overall survival (OS), and tumor response in metastatic breast cancer patients and to correlate the BCSC expression with different clinicopathological parameters. Material. This prospective study enrolled 76 de novo metastatic breast cancer patients recruited from the Oncology Center, Mansoura University, Egypt, with a minimum age 31 years and a maximum of 70 years. Pretreatment BCSC markers (CD44 and CD24) were assessed by immunohistochemistry on formalin-fixed paraffin-embedded tumor tissues from a primary or metastatic site. Patients received different lines of treatment, hormonal or chemotherapy, according to their biological subtypes. Anti-Her2 was added for Her2-positive patients. Results. Thirty-three patients (43.4%) were premenopausal and 43 patients (56.6%) were postmenopausal. Bone-only metastasis was seen in 12 patients (15.7%), however, visceral ± bone metastasis was seen in 64 patients (84.3%). BCSC markers (CD44+ve and CD24−ve) were expressed in 32 patients (42.1%), while 44 patients (57.9%) were not expressing BCSC markers. Out of 32 patients expressing BCSC, 22 patients (68%) were premenopausal and 28 patients (87.5%) were with high-grade (GIII) disease. BCSC was significantly presented in triple negative subtype breast cancer as there were 32 patients with the BCSC expression, and out of them, 15 patients (46.9%) had triple negative disease, 10 patients (31.3%) had luminal subtype, and seven patients (21.9%) were Her2-amplified, while there were 44 patients without BCSC expression, and out of them, 30 patients (68.2%) were of the luminal subtype, no patient (20.5%) had triple negative disease, and five patients (11.4%) were Her2-amplified (P 0.006). Twenty-four patients (31.5%) presented with visceral crisis; out of them, 17 patients (70.1%) were expressing BCSC which also denoted more aggressive disease. Seventy-four patients were candidates for the response assessment. BCSC-expressing patients showed poor response compared to non-BCSC (16.1% responsive versus 51.2%, respectively), with a significance relation (P 0.003). The BCSC expression was associated with both significant short PFS (median, 18 months vs. 35 months; P=0.001) and short OS (median, 26 months vs. 43 months; P=0.003). In multivariate analysis; BCSC expression was an independent prognostic factor for poor OS (P=0.055) along with the molecular subtype (P=0.012), Her2 status (P=0.011), and histologic grade (P=0.037). Conclusion. This study further validates the BCSC expression as a poor prognostic biomarker correlated with poor response, short PFS and OS. So, it could be used as a marker for tailoring treatment with different lines of therapies in further studies. The BCSC expression was highly presented in the triple negative subtype which is an aggressive disease that lacks different targets. So, targeting BCSC may carry a hope in future for this group of patients.

Abstract Background Identification of specific biological functions, pathways, and appropriate prognostic biomarkers is essential to accurately predict the clinical outcomes of and apply efficient treatment for breast cancer patients. Methods To search for metastatic breast cancer-specific biological functions, pathways, and novel biomarkers in breast cancer, gene expression datasets of metastatic breast cancer were obtained from Oncomine, an online data mining platform. Over- and under-expressed genesets were collected and the differentially expressed genes were screened from four datasets with large sample sizes (N > 200). They were analyzed for gene ontology (GO), KEGG pathway, protein-protein interaction, and hub gene analyses using online bioinformatic tools (Enrichr, STRING, and Cytoscape) to find enriched functions and pathways in metastatic breast cancer. To identify novel prognostic biomarkers in breast cancer, differentially expressed genes were screened from the entire twelve datasets with any sample sizes and tested for expression correlation and survival analyses using online tools such as KM plotter and bc-GenExMiner. Results Compared to non-metastatic breast cancer, 193 and 144 genes were differentially over- and under-expressed in metastatic breast cancer, respectively, and they were significantly enriched in regulating cell death, epidermal growth factor receptor signaling, and membrane and cytoskeletal structures according to the GO analyses. In addition, genes involved in progesterone- and estrogen-related signalings were enriched according to KEGG pathway analyses. Hub genes were identified via protein-protein interaction network analysis. Moreover, four differentially over-expressed (CCNA2, CENPN, DEPDC1, and TTK) and three differentially under-expressed genes (ABAT, LRIG1, and PGR) were further identified as novel biomarker candidate genes from the entire twelve datasets. Over- and under-expressed biomarker candidate genes were positively and negatively correlated with the aggressive and metastatic nature of breast cancer and were associated with poor and good prognosis of breast cancer patients, respectively. Conclusions Transcriptome datasets of metastatic breast cancer obtained from Oncomine allow the identification of metastatic breast cancer-specific biological functions, pathways, and novel biomarkers to predict clinical outcomes of breast cancer patients. Further functional studies are needed to warrant validation of their roles as functional tumor-promoting or tumor-suppressing genes.
