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.

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.

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.
