Case 1 • The patient decides to proceed to myeloablative therapy + autologous stem cell transplant (AuSCT) • Therapy is held for 2.5 weeks and an attempt to harvest stem cells with G-CSG (filgastrim) alone is unsuccessful What would you do next? 1. Tell the patient that harvest was unsuccessful and continue chemotherapy 2. Attempt harvest after cyclophosphamide mobilization therapy (+/- mobizil) Case 1 • Autologous stem cell harvest is successful after cyclophosphamide chemomobilization and the patient proceeds with high-dose melphalan + autologous stem cell transplant (AuSCT) • 3 months post- AuSCT the patient is started on lenalidomide maintenance therapy 10 mg po daily Case • 3 months post- AuSCT the patient restarts zoledronic acid monthly after previously being cleared by the dentist • M-protein reduces to 0, but immunofixation remains positive at 6 months post-AuSCT Case • The patient develops right lower jaw pain and is evaluated by the dentist and has an abscess, which responds to antibiotic therapy, but the tooth needs extraction. What would you do regarding the extraction? 1. Have the tooth extracted immediately. 2. Stop zoledronic acid and have the tooth extracted immediately. 3. Hold zoledronic acid, treat the tooth, wait at least 1 month, if possible, and extract the tooth. Case • The patient has the tooth extracted and after 3 months zoledronic acid is restarted. • The patient continues on lenalidomide 10mg/d in near CR by SPEP • 1 year post-AuSCT the patient’s creatinine begins to rise and is 1.97mg/dL (creatinine clearance 33 ml/min) • 24 hr UPEP reveals a rise in total protein to 453 mg/d (Bence Jones protein 7 mg/d) : previous total proteinuria 87 mg/d with 5 mg Bence Jones protein What would you do regarding the creatinine? 1. Change therapy the patient’s disease is progressing 2. Stop zoledronic acid and repeat UPEP in 1 month 3. Dose adjust lenalidomide Lenalidomide Creatinine Clearance (m/min) Lenalidomide Dose (mg) > 30 - 50 10 mg/Day < 30, NOT on dialysis 15 mg q48 hours On dialysis 5 mg/D after dialysis Celgene Product Information available at www.
