High-dose chemoradiotherapy with syngeneic bone marrow transplantation for multiple myeloma: a case report and literature review.
We had the opportunity to treat a patient with progressive heavily pretreated multiple myeloma with high-dose chemoradiotherapy with hematopoietic rescue by syngeneic bone marrow transplantation. The patient was a 53-year-old male who had previously received melphalan, prednisone, 1,3-bis (2-chloroethyl)-l-nitrosourea (BCNU), vincristine, and standard radiation therapy. At the time of bone marrow transplantation, he had increasing bone pain, increasing M-protein (IgG kappa), and a bone marrow diagnostic of myeloma. The transplant regimen consisted of cyclophosphamide, 60 mg/kg intravenously for 2 days, and total body irradiation--1,200 rads given as 200-rad fractions, twice daily for three days. The transplant course was complicated by confusion, herpes simplex mucositis, fever, and two episodes of idiopathic diffuse interstitial pneumonia. Over the next 2 years the patient did well and was in immunologic and bone marrow complete remission. Unfortunately, 3 years after treatment, the myeloma relapsed with detectable M-protein. Three and one-half years after transplant, clinical relapse occurred with bone pain and lytic lesions necessitating additional radiation and chemotherapy. Salvage therapy has produced clinical improvement and the patient is alive almost 4 years from transplant and almost 7 years from diagnosis. Although intense chemoradiotherapy did not cure this patient, substantial control of a refractory tumor was observed. This case, together with other cases of intense therapy for myeloma which are reviewed in this paper, support the concept of high-dose therapy and should foster further investigation of high-dose therapy.
