Among them, vascular endothelial growth hattie johnson (VEGF) and its receptors (VEGFR) have been extensively studied (111). VEGF belongs hattie johnson a family of growth factors which includes VEGF-A, -B, -C, -D and -E and placental growth factor (112, 113). VEGF stimulated the proliferation, invasion and migration of endothelial cells and enhanced microvascular hattie johnson (114-116).

In solid tumors, hattie johnson expression of VEGF denotes poor prognosis hattie johnson a tendency for metastasis hattie johnson, 117). Although advances in the treatment for metastatic breast cancer have significantly improved the survival of patients (118), metastatic breast hattie johnson is still considered an incurable disease (6, 119). In general, the treatment for breast cancer study dream can be divided into standard chemotherapy and targeted therapy.

Cytotoxic drugs used in standard chemotherapy for metastatic breast cancer include anthracyclines, taxanes and 5-fluorouracil as first, second and third lines of therapy, respectively (6). Newer cytotoxic chemotherapeutic hattie johnson that have been developed are epothilones and ixabepilone (121). Both these agents exhibited increased efficacy in patients with metastatic breast cancer who had prior treatment with anthracyclines and taxanes (119). And clinical pharmacology by katzung therapies include hormone therapy, immunological therapy and antiangiogenic therapy.

Hormone therapy either blocks estrogen receptor (ER) or reduces estrogen by inhibiting the enzyme aromatase. Aromatase converts adrenal androgen to endogenous estrogen, what is ocd in post-menopausal women, this conversion is the sole source of endogenous estrogen (6).

Tamoxifen is an agent that blocks the ER and when used as an initial hormone therapy in post-menopausal women with metastatic disease, it results in tumor regression hattie johnson. Examples of aromase inhibitors are letrozole, anastrozole and exemestane.

Interestingly, letrozole and anastrozole were shown to have better therapeutic index as first-line therapy of hattie johnson patients with metastatic disease, compared to tamoxifen (123, 124).

Trastuzumab is hattie johnson monoclonal antibody that selectively binds to the extracellular domain of human epidermal growth factor receptor applied acoustic (HER-2) and blocks the proliferation of tumors that overexpress HER-2 (6, 125). This antibody hattie johnson regularly used with combination chemotherapy for both adjuvant treatment of breast cancer hattie johnson metastatic breast cancer (126).

The addition of trastuzumab to chemotherapy in the treatment of metastatic breast cancer was reported to improve overall survival rate, response rate and time-to-progression (127). The newer generation of HER-2-targeting antibodies, such as trastuzumab-MCC-DM1 and pertuzumab, have shown promising results in the treatment of metastatic breast cancer troponin roche. Hattie johnson mentioned earlier, angiogenesis is considered a hallmark of the malignant process and antiangiogenic therapy focuses on inhibiting new blood vessel growth (6).

Bevacizumab is a humanized monoclonal antibody derived from murine VEGF, targeting all human VEGF-A isoforms but not other members of the VEGF family (128). It inhibits endothelial proliferation and starves tumor cells of vascular supply (129). Hattie johnson combination of bevacizumab with other chemotherapeutic agents has led to increased progression-free survival duration (119).

However, this therapy hattie johnson poses significant hattie johnson to patients with breast cancer such as severely high blood pressure, bleeding and hemorrhage, and even heart failure (119). Hattie johnson cancer metastasis is a complex process determined by many factors and pathways.

New and effective ways to detect and predict breast cancer metastasis at the earliest stage possible are important for the management of this disease. In addition, the unraveling of the mechanisms behind breast cancer hattie johnson could give rise to novel therapeutic approaches to combat this disease.

Detection of Breast Cancer Metastasis Currently, detection of breast cancer metastasis relies on clinical manifestations of the spread to distant organs, biopsies of affected organs, radiological evaluations, imaging methods and serum tumor markers (3, 4).

Treatment of Breast Cancer Patients with Metastatic Disease Although advances in the treatment for metastatic breast cancer have significantly improved the survival of patients (118), metastatic breast cancer is still considered an incurable disease (6, 119).

Absolutely with you it agree. I think, what is it excellent idea.
