A cancer test having prognostic utility in predicting time to disease progression, overall survival, and response to therapy in patients with MBC based upon the presence and number of CTC's. The Cell Spotter® System is used to enumerate CTC's in blood. The system immunomagnetically concentrates epithelial cells, fluorescently labels the cells and identifies and quantifies CTC's. The absolute number of CTC's detected in the peripheral blood tumor load is, in part, a factor in prediction of survival, time to progression, and response to therapy. The mean time to survival of patients depended upon a threshold number of 5 CTC's per 7.5 ml of blood. Detection of CTC's in metastatic cancer represents a novel prognostic factor in patients with metastatic cancers, suggests a biological role for the presence of tumor cells in the blood, and indicates that the detection of CTC's could be considered an appropriate surrogate marker for prospective therapeutic clinical trials.

Neutropenia is the dose-limiting toxicity of the tri-weekly docetaxel (Taxotere®) schedule. Here, we evaluate in Metastatic Breast Cancer (MBC) patients (N=38) a computerized method for predicting docetaxel-induced neutropenia, and use the model to identify improved docetaxel and Granulocyte Colony Stimulating Factor (G-CSF) regimens. Pharmacokinetics / pharmacodynamics (PK / PD) models were created and simulated concomitantly with a mathematical granulopoiesis model. Individual baseline neutrophil counts and docetaxel schedules served as inputs. Our trial validated the model accuracy in predicting nadir timings (r=0.99), grade 3 / 4 neutropenia (86% success) and neutrophil profiles (r=0.62). Model was robust to CYP3A-induced variability, except for slightly less accurate grade 3 / 4 neutropenia predictions. Simulations confirm smaller toxicity of the weekly docetaxel regimen than the tri-weekly one, and suggest an optimal G-CSF support for alleviating neutropenia, 60 μg / day QD×3, 6-7 days post-docetaxel, administered tri- and bi-weekly, and 4 days post weekly docetaxel>33 mg / m2.

A novel inhibitor of Rac activity based on the structure of the established Rac / Rac-GEF inhibitor NSC23766 is discloses. The compound EHop-016, with an IC50 of 1.1 μM, is a 100-fold more efficient inhibitor of Rac activity than NSC23766. EHop-016 is specific for Rac1 and Rac3 at concentrations ≦5 mM. At higher concentrations, EHop-016 inhibits the close homolog Cdc42. In MDA-MB-435 cells, EHop-016 (≦5 mM) inhibits the association of the Rac-GEF Vav2 with a nucleotide-free Rac1(G15A), which has a high affinity for activated GEFs. EHop-016 does not affect the association of the Rac-GEF Tiam-1 with Rac1(G15A) at similar concentrations. EHop-016 also inhibits the Rac activity of MDA-MB-231 metastatic breast cancer cells and reduces Rac-directed lamellipodia formation in both cell lines. EHop-016 decreases Rac-downstream effects of p21-activated kinase (PAK)1 activity and directed migration of metastatic cancer cells. At low concentrations (<5 μM), EHop-016 does not affect cell viability.

An extract of Scutellaria Barbata D. Don is effective in the arrest of cancer cell growth. The extract of Scutellaria Barbata D. Don may be used as a therapeutic treatment for patients who have been identified as having cancer. In some situations, a patient is identified as having a type of cancer by detecting the presence of a biomarker for that cancer in the patient's system and by further determining the level of that biomarker in the patient's system. If the level of the biomarker is above a predetermined threshold level for that biomarker, the patient may be diagnosed with cancer. Subsquently, treatment using an extract of Scutellaria Barbata D. Don may begin. Biomarkers of interest in the detection of the presence of metastitic breast cancer include 8-oxoguanine and lactate dehydrogenase.

This patent describes a method and materials to treat cancer diagnosed at an early stage, particularly breast cancer. It considers that metastatic breast cancer growth includes periods of dormancy, that surgery to remove a primary tumor can induce metastatic growth, and that women with Down Syndrome rarely get breast cancer. It elevates the level of an antiangiogenic drug produced by chromosome 21 preferably Endostatin in plasma preferably at least one day prior to surgery and kept at that high level preferably indefinitely. The therapy specifically excludes drugs that significantly inhibit the VEGF pathway since that is important for wound healing. This method will prevent results of surgery from stimulating tumor growth and angiogenesis of micrometastatic disease that is much easier to prevent than control after the fact. This can be done indefinitely since there is no acquired resistance that develops, as happens in most cancer therapies.
