Method for diagnosis and treatment of prostate cancer

In a method for diagnosis and treatment of a patient with a tumor relating to prostate cancer, the following steps are implemented. A differential diagnosis of prostate cancer versus prostatitis and / or BPH is conducted on a patient using a cost-effective diagnosis method. If prostate cancer is diagnosed in the patient using a cost-effective measurement method, a characteristic value for the tumor aggressiveness of the prostate cancer is determined. A watchful waiting treatment is implemented with the patient given a characteristic value below a predeterminable first limit value. The size and position of the tumor is determined using a cost-effective method given a characteristic value above the first limit value. A cost-effective ultrasonic theranosis or a conventional therapy is conducted for a size below a second predeterminable limit value. The presence of metastases in the patient is checked, with a cost-intensive method generating image information, for a size above the second limit value. A metastasis treatment is implemented in the event that metastases are present. In the event that no metastases are present, a tumor treatment based on the aforementioned image information generated is implemented.

Blood test to monitor the genetic changes of progressive cancer using immunomagnetic enrichment and fluorescence in situ hybridization (FISH)

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.

CA IX-specific inhibitors

Therapeutic methods for inhibiting the growth of preneoplastic / neoplastic vertebrate cells that abnormally express MN protein are disclosed. Screening assays are provided for identifying compounds, preferably organic compounds, preferably aromatic and heterocylic sulfonamides, which inhibit the enzymatic activity of MN / CA IX and that are useful for treating patients with preneoplastic / neoplastic disease. Further, the CA IX-specific inhibitors when labeled or linked to an appropriate visualizing means can also be used diagnostically / prognostically for preneoplastic / neoplastic disease, and for imaging use, for example, to detect hypoxic precancerous cells, tumors and / or metastases, by selectively binding to activated CA IX, preferably CA IX activated under hypoxic conditions, and not to inactive CA IX. Such detection of hypoxic conditions can be helpful in determining effective treatment options, and in predicting treatment outcome and the prognosis of disease development. Still further, the CA IX-specific inhibitors can be used therapeutically to selectively target hypoxic cells expressing activated CA IX. The CA IX-specific inhibitors can be labelled or conjugated to radioisotopes for radiotherapy of hypoxic cells. Alternatively, the CA IX-specific inhibitors can be used for gene therapy coupled to vectors for targeted delivery to hypoxic preneoplastic / neoplastic cells expressing activated CA IX on their surfaces. In an alternative mode of the invention, CA IX-specific inhibitors may be used therapeutically to target acidic conditions of a tumor, e.g., to increase pHe in order to enhance the efficacy of weak base chemotherapeutic drugs.

Targeting metastasis stem cells through a fatty acid receptor (CD36)

Metastasis stem cells are targeted through a fatty acid receptor. Blockers or inhibitors of CD36 activity or expression are for the treatment of oral squamous cell cancer (OSCC), particularly for the treatment of generated metastases and for diminishing generation from primary tumors. Apart from shRNAs, anti-CD36 antibodies are provided as blockers or inhibitors, especially those that block the binding of CD36 to oxidized LDL and fatty acids and their incorporation into cells, because the promotion of their transport is indicated as the mechanism by which CD36 promote metastases dissemination and growth. A method identifies candidates to anticancer agents, particularly for OSCC metastasis, among those that promote in CD36+ cells, in vivo or in vitro, effects associated to CD36 depletion or blocking such as decrease of growth accumulation of lipid droplets and decrease of size in the case of metastases.
