PathWays Case Study: Sept. 19

Following three years of disease-free status, a patient presented with a recurrent monoclonal IgGK immunoglobulin during a routine follow-up evaluation (PEL 1). Therapy was reinstated and consisted of daratumumab, lenalidomide, and dexamethasone. Despite clinical improvement, two detectable monoclonal proteins of IgGΚ isotype were found on follow-up a month later (PEL 2, and IFE). The primary clone had declined in concentration from 0.8 g/dL to 0.4 g/dL while the second (new) clone could not be quantitated.
