Abstract

The isoenzyme creatine kinase muscle/brain (CK-MB) still plays an important role for the differential diagnosis of CK elevations and the clarification of their origin from heart or skeletal muscle. Therefore, it is necessary to know the diagnostic pitfalls in interpreting CK-MB results. We demonstrate a case of macro-CK type 2 in a 75-year-old patient with metastatic castration-resistant prostate cancer and its identification by isoenzyme electrophoresis, which can be typical for cancer diseases.

Keywords: agarose gel electrophoresis; castration-resistant; CK; CK isoenzyme; CK-MB; creatine kinase; immunoinhibition assay; macro-CK; metastatic; prostate cancer
