The invention relates to the use of enzymes and nanorods to detect cysteine level in a patient sample and relates to the use of the detected cysteine level to predict cancer recurrence in the patient. The invention is directed to systems and methods of detecting cysteine level in a sample from a subject, wherein the systems or methods can further comprise measuring at least one additional parameter, such as PSA level, Gleason score and clinical stage. The invention is directed to systems and methods of predicting the probability of a recurrence of a cancer in a subject, wherein the systems or methods can further comprise measuring at least one additional parameter, such as PSA level, Gleason score and clinical stage. This invention is directed to systems and methods of predicting the probability of a recurrence of a cancer in a subject and treating the subject, wherein the systems or methods can further comprise measuring at least one additional parameter, such as PSA level, Gleason score and clinical stage. |
