Prostate Cancer: MR Imagingguided GalvanotherapyTechnical Development and First Clinical Results
Table E1. PSA Values during Study Course, Size Reduction of Prostate, and Results of Three Posttherapy Follow-ups

Note.PSA values were obtained before MR imaging–guided galvanotherapy (PSA 1), 3 months after therapy (PSA 2), 6 months after therapy (PSA 3), and 12 months after therapy (PSA 4). CR = complete remission (decrease in tumor size of 100%), PD = progressive disease (increase in tumor size), PR = partial remission (decrease in tumor size of more than 30%), SD = stable disease (decrease in tumor size of up to 30%).
* Percentage decrease in tumor volume after 12 months.
