A medicament based on antibodies contains an activated form of ultra-low doses of monoclonal, polyclonal, or natural antibodies to the prostate-specific antigen, the activated form being prepared by multiple consecutive dilutions and exposure to external factors, preferably according to homeopathic technology. In order to obtain the antibodies, the prostate-specific antigen isolated from the prostatic tissues of cattle or prepared synthetically is employed; a mixture of various, mostly centesimal, homeopathic dilutions is used. The method of treating diseases of the urogenital sphere consists in using activated forms of ultra-low doses of antibodies to prostate-specific antigen prepared by multiple consecutive dilutions and exposure to external factors.

The development of a high-throughput multi-antigen microfluidic fluorescence immunoassay system is illustrated in a 100-chamber PDMS (polydimethylsiloxane) chip which performs up to 5 tests for each of 10 samples. Specificity of detection is demonstrated and calibration curves produced for C-Reactive Protein (CRP), Prostate Specific Antigen (PSA), ferritin, and Vascular Endothelial Growth Factor (VEGF). The measurements show sensitivity at and below levels that are significant in current clinical laboratory practice (with SIN>8 at as low as 10 pM antigen concentration). The chip uses 100 nL per sample for all four tests and provides an improved instrument for use in scientific research and “point-of-care” testing in medicine.

Methods of prognosis of prostate cancer
The present invention applies classical survival analysis to genome-wide gene expression profiles of prostate cancers and preoperative prostate-specific antigen levels from prostate cancer patient, to identify prognostic markers of disease relapse that provide additional predictive value relative to prostate-specific antigen concentration. The present invention provides a method of determining prognosis of prostate cancer and predicting prostate cancer outcome of a patient. The method comprises the steps of first establishing the threshold value of at least one prognostic gene of prostate cancer. Then, the amount of the prognostic gene from a prostate tissue of a prostate cancer patient is determined. The amount of the prognostic gene present in that patient is compared with the established threshold value of the prognostic gene, whereby the prognostic outcome of the patient is determined.

We have discovered a protein in humans, herein referred to as thymosin R16 (SEQ ID NO: 1), that is expressed in human prostate cancer tumors but not in specimens of benign prostate hyperplasma (BPH) tissues. In contrast, prostate specific antigen (PSA), the gold standard of prostate cancer diagnosis, is highly expressed in BPH tissues. Increased expression of thymosin (316 has a high correlation to disease state in a number of cancers including prostate cancer and cancers of epithelial origin.

Enhanced diagnostic potential of prostate-specific antigen expressing cells
The present invention is directed to sensitive and specific methods and kits for the detection of prostate cancer in a patient. The invention uses RT-PCR to detect the expression or change in expression of PSA in epithelial cells enriched from whole blood. The methods and kits on the invention represent a a significant improvement over previous methods of CaP diagnosis. According to one embodiment, prostate epithelial cells are isolated from blood and the RNA subjected to RT-PCR. The resulting cDNA is subjected to traditional PCR amplification with primers able to distinguish between the genomic copy of the gene and the cDNA copy resulting from CaP gene expression. This method provides an assay which is more sensitive, specific and reproducible as compared to conventional methods. Results disclosed herein demonstrate a correlation between the presence of PSA-expressing prostate epithelial cells with cancer recurrence which provides a diagnostic tool for the early detection of prostate disease.
