The present invention provides methods of monitoring and measuring tumor-associated free PSA ('fPSA') with antibody polypeptides as an indication of androgen receptor signaling. In a particular embodiment, the methods may be used to assess the efficacy of anti-androgen and/or general anti-cancer treatments. The present invention also provides various methods and compositions relating to antibodies that are specific for tumor-associated or intratumoral fPSA. For example, the present invention provides compositions, including pharmaceutical compositions, comprising anti-fPSA antibodies, or fragments or characteristic portions thereof. The present invention further provides various therapeutic and/or diagnostic methods of using anti-fPSA antibodies and/or compositions.

Free PSA antibodies as diagnostics, prognostics and therapeutics for prostate cancer

The present disclosure describes a non-linear compartmental model using PET-derived data to predict, on a patient-specific basis, the optimal therapeutic dose of cargo carrying antibody (e.g., huA33) such as radiolabeled antibody, the antigen occupancy, residency times in normal and malignant tissues, and the cancer-to-normal tissue (e.g., colorectal cancer-to-normal colon tissue) therapeutic index. In addition, the non-linear compartmental model can be readily applied to the development of strategies such as multi-step targeting (MST) designed to further improve the therapeutic indices of RIT.

Systems and methods for determining optimum patient-specific antibody dose for tumor targeting

Methods for diagnosing prostate cancer, and differentiate prostate cancer from other prostate complications, and use of said method, and diagnosing and monitoring lymph gland metastasis, post operative examinations, and examinations during or after radiation, cytostatic, and androgen treatments are disclosed. The methods comprise injecting tracer-labelled PSA or hK2 specific antibodies, visualising PSA or hK2 producing tissue with the aid of a visualization method, and diagnosing prostate cancer from the difference in visualization.
