Lenalidomide is commonly used as induction or maintenance therapy in multiple myeloma. We report a case of 71-year-old female presenting with tardive dyskinesia-like symptoms one month after starting her lenalidomide maintenance therapy after high-dose chemotherapy and autologous hematopoietic stem cell rescue. Her symptoms evolved over days to pronounced uncontrollable limb movements, tongue smacking, lip-smacking, abnormal sounds, and tongue biting. The patient categorically denied any exposure to other drugs which are known to cause symptoms of tardive dyskinesia. The patient underwent a thorough evaluation, stopped the lenalidomide, and received therapy to control her symptoms with a gradual improvement over a six-week period. There is a paucity of literature on the association of lenalidomide with tardive dyskinesia. Common central nervous system-related side effects include peripheral neuropathy, dizziness, dysgeusia, headache, tremor, somnolence, and memory impairment. Very few studies in the existing literature have reported an association of tardive dyskinesia with lenalidomide therapy. Here, we present a case of an elderly female with multiple myeloma who developed severe tardive dyskinesia while she was on lenalidomide maintenance therapy.

The prognosis of elderly patients with acute myeloid leukemia (AML) is poor. Intensive chemotherapy with the combination of cytarabine and anthracyclines is typically used as the first-line treatment in the elderly with newly diagnosed AML who are able to tolerate this regimen. Unfortunately, many patients are refractory to this treatment approach. The role of hypomethylating agents in the treatment of elderly patients with refractory AML has not been clearly defined. Therefore, we conducted a focused literature review to assess the role of hypomethylating agents in elderly patients with refractory AML. In addition, we present a case report of a patient with refractory AML, who was subsequently treated with azacytidine and showed an immediate response after one treatment cycle. He then proceeded to undergo nine more cycles. Ten months after the start of treatment with azacytidine, he remains in complete remission with incomplete hematologic recovery. Given the positive results noted in multiple retrospective studies and in the presented case report, large-scale, prospective studies are needed to further define the role of hypomethylating agents in the treatment of elderly patients with refractory AML.

We report a case of a patient with relapsed Ewing’s sarcoma (ES). After receiving conventional chemotherapy (CC) and noticing chemosensitivity of the disease, we proceeded to give the patient two separate cycles of HDCT consisting of a melphalan/busulfan regimen in the first cycle and etoposide/melphalan in the second cycle. The patient proceeded to get an autologous stem cell transplant (ASCT) after each cycle of HDCT. Our patient, despite multiple poor prognostic factors, including advanced age and multiple sites of disease relapse, showed a one-year event-free survival. Relapsed ES is associated with a poor prognosis. No treatment regimen has yet been established as a standard of care in patients with relapsed ES. We conducted a focused literature review to assess the efficacy of high-dose chemotherapy (HDCT) followed by ASCT in patients with relapsed ES. Given the improved survival outcome with HDCT followed by ASCT in our patient, we propose that its role in relapsed ES needs further assessment through large prospective, randomized controlled studies.
