A small percentage of cells within an established solid tumor have the properties of stem cells. These solid tumor stem cells give rise both to more tumor stem cells and to the majority of cells in the tumor that have lost the capacity for extensive proliferation and the ability to give rise to new tumors. Thus, solid tumor heterogeneity reflects the presence of tumor cell progeny arising from a solid tumor stem cell. We have developed a xenograft model in which we have been able to establish tumors from primary tumors via injection of tumor cells in the mammary gland of severely immunodeficient mice. These xenograft assay have allowed us to do biological and molecular assays to characterize clonogenic solid tumor stem cells. We have also developed evidence that strongly implicates the Notch pathway, especially Notch 4, as playing a central pathway in carcinogenesis.

The present invention refers to a composition based on monoterpenes with chemopreventive and chemotherapeutic effects in malignant neoplasias of humans and animals containing from 0,03% to 30% of monoterpenes and 99,97% of solvents. Another objective of the present invention is an application of monoterpenes in inhibition of cell growth and metastasis control of primary tumors being applied in vitro and in vivo gliomas cell lines C6 and U 87 and A172. Further another objective of the present invention refers to a specific methods for applying the composition with chemopreventive and chemotherapeutic effects in humans and animals showing malignant neoplasias by inhalation and nebulization treatment, oral and intratumoral, followed or not by radiotherapy with dilutions from 0,03% to 30% of the monoterpene perillyl or its derived metabolites diluted in the solvents specified by the usual techniques.

S-band, C-band or X-band microwave powered linear accelerators capable of delivering therapeutic photon and electron beams are mounted to a gantry with extensions to hold multiple accelerators and are combined with a kV CT for 3-D conformal—IMRT and IGRT to treat a patient by SSD or SAD methods and in a full circle. The invention's tertiary collimator system consists of semi-automated reusable custom field shaping with tungsten powder or melted Cerrobend blocks. The beam's intensity modulation is by means of simultaneous but independently operating multiple accelerators. This system's multiple accelerators enable to avoid interrupted subfractionated radiation therapy to each treatment fields. Hence its effective dose rate at the tumor site is high. The improved radiobiology reduces the total radiation dose to treat a tumor, reducing the incidence of developing second primary tumors is also minimized.

Amplification and overexpression of theHER-2 oncogene in breast cancer is felt to be stable over the course of disease and concordant between the primary tumor and metastases. Therefore, patients with HER-2 negative primary tumors will rarely receive anti-HER-2 antibody therapy. A very sensitive blood test is used to capture circulating tumor cells (CTC's) and evaluate their HER-2 gene status by FISH evaluation. The HER-2 status of the primary tumor and corresponding CTC's is used to assess the ratio of CTC's as a reliable surrogate marker. HER-2 expression of 10 CTC's is sufficient to make a definitive diagnosis of the HER-2 gene status for the whole population of CTC's in patients with recurrent breast cancer.
