BACKGROUND: In the adjuvant treatment of breast cancer, anthracycline and taxane based regimens can be used concomitantly or sequentially. The best order in the sequential regimens has yet to be well established. This study evaluated the feasibility of 4 cycles of adjuvant taxotere (100mg/m2) every 3 weeks followed by 4 cycles of doxorubicin (60 mg/m2) and cyclophosphamide (600mg/m2) every 3 weeks. The primary outcome was the safety profile. Secondary outcomes were disease free survival (DFS) and overall survival (OS)...

Studies have raised concern about the safety of generic compared with branded drugs. Febrile neutropenia (FN) resulting in hospital admission was compared between the branded docetaxel (Taxotere®, Sanofi) and two generic formulations (docetaxel Ebewe and docetaxel Hospira) in patients with breast cancer. This was a retrospective study that included patients with breast cancer who received docetaxel between January, 2012 and December, 2014. Patients who had an admission diagnosis of FN and had received docetaxel within 14 days prior to admission were evaluated...

The design of nanomedicines with suitable physicochemical characteristics for the lymphatic targeting of drugs is critical in order to reach the lymph nodes, where metastatic cells often accumulate. Based on the known effect of particle size and surface hydrophilicity on the capacity of nanocarriers to reach the lymph nodes, here we report the formation and characterization of 100nm polyglutamic acid-polyethylene glycol (PGA-PEG) nanocapsules together with the assessment of their potential for the treatment of cancer with lymphatic metastatic spread...

Accumulating data suggests that the initiation and progression of human breast tumors is fueled by a rare subpopulation of tumor cells, termed breast tumor-initiating cells (BTIC), which resist radiotherapy and chemotherapy. Consequently, therapies that abrogate BTIC activity are needed to achieve durable cures for breast cancer patients. To identify such therapies we used a sensitive assay to complete a high-throughput screen of small molecules, including approved drugs, with BTIC-rich mouse mammary tumor cell populations...

OBJECTIVE: Chemoresistance remains a major challenge in the treatment of ovarian cancer. As part of a survival mechanism, tumor cells have been shown to release proangiogenic factors, such as vascular endothelial growth factor (VEGF), through a mechanism that involves the upregulation of hypoxia-induced factor (HIF)-1α. The objective of this study was to compare the expression of VEGF and its receptors (R1 and R2) as well as HIF-1α in chemoresistant epithelial ovarian cancer (EOC) cells to their chemosensitive counterparts and determine their impact on angiogenesis...

PURPOSE: Recently, efficacy studies in mice have shown that amine-terminated cationic (CNP) nanoparticulate carriers of DTX offer an improved formulation of the drug for intravesical delivery. It is hypothesized that this improved efficacy may arise from a carrier mediated bladder exfoliation process that removes the urothelial barrier allowing for increased drug uptake into bladder tissue. The objective of this study was to investigate exfoliation processes in fresh pig's bladders (ex vivo) exposed to three cationic polyglycerols with increasing degrees of amination (denoted 350, 580 and 780)...

There is a strong desire to develop docetaxel (DTX) formulation with good therapeutic effectiveness in view of serious adverse reactions of the commercial formulation of DTX (Taxotere®). In this study, a redox-responsive DTX-vitamin E prodrug was successfully formulated into liposomes with the drug loading of 4.14% ± 0.10%. Compared with DTX liposomes, the DTX prodrug liposomes (DPLs) showed good stability for 30-d shelf life and during dilution with different media. In vitro antitumor activity of DPLs on human prostatic carcinoma PC-3 cells and human lung cancer A549 cells was evaluated using cytotoxicity and apoptosis assays...

Male breast cancer is an extremely rare malignancy. We treated three male breast cancer patients. All three patients showed clinical N0 and received sentinel lymph node biopsy. Because the sentinel lymph node was positive for metastasis in one patient, a total mastectomy with axillary lymph node dissection was performed. The other two patients were negative for sentinel lymph node metastasis, and a simple mastectomy was performed. Two of the patients were postoperatively treated with tamoxifen; another patient was treated with adjuvant chemotherapy using taxotere and cyclophosphamide before tamoxifen...

In this study, we reported a simple polydopamine (pD)-based surface modification method to prepare novel nanoparticle-aptamer bioconjugates (Apt-pD-DTX/NPs) for in vivo tumor targeting and enhanced therapeutic effects of breast cancer. With simple preparation procedures, the new functionalized Apt-pD-DTX/NPs could maximumly increase the local effective drug concentration on tumor sites, achieving enhanced treatment effectiveness and minimizing side effects. The dopamine polymerization and aptamer conjugation barely changed the characters of NPs...

PURPOSE: The combination of taxanes and anthracyclines has proven efficacy in node-positive (N+) premenopausal primary breast cancer patients. Ovarian ablation is also associated with better survival outcomes in premenopausal hormone-receptor positive (HR+) patients. Therefore, this trial aims to determine the superiority of combined hormonal treatment of ovarian ablation with tamoxifen (TMX) versus TMX alone, in premenopausal N+, HR + patients receiving adjuvant chemotherapy (AC) with taxane and anthracycline...

Nasopharyngeal carcinoma (NpC) is rare in the west but common in Southeast Asia and only a few other locations. With the limited geographic incidence, it is relatively under-studied. It also has as co-determinant the Epstein-Barr virus (EBV), which may adapt to NpC therapies, so not only must a therapeutic compound be found, the discovery process must be rapid, to cope with the changing basis of the EBV. An R-based computer workbench, Mendel, was developed so biologists could quickly upload genomic data, pre-process them, and identify upregulated and downregulated genes...
