Abstract:
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.An 84-year-old woman presented with bone pain and lytic bone lesions in April 2010. Diagnosis of multiple myeloma was based on the presence of an immunoglobulin G lambda serum M protein (4,784 mg/dL) and confirmed by the findings of bone marrow plasma cell infiltration, with t(11;14) chromosomal abnormality detected by fluorescence in situ hybridization analysis. The patient's medical history was significant for hypertension; she had an Eastern Cooperative Oncology Group performance status of 1, International Staging System (ISS) stage of 1, and Durie-Salmon stage of IIIA. In May 2010, the patient was enrolled in a randomized phase III trial comparing different lenalidomide-based treatments and received induction with lenalidomide plus dexamethasone (nine cycles) followed by lenalidomide maintenance. The patient started treatment with lenalidomide 25 mg per day for 21 days and reduced-dose dexamethasone 20 mg per week per protocol because of age. Induction was well tolerated; no relevant complications occurred, except for grade 1 fatigue and grade 1 diarrhea. Best response was partial response. In March 2011, she started maintenance with lenalidomide 10 mg per day. A dose reduction of lenalidomide 5 mg per day was required because of grade 2 diarrhea. In July 2015, the patient experienced relapse, with painful collapse of L3 vertebral body.
