We report a case of a female patient with Durie-Salmon stage 3A/ISS stage I IgG kappa multiple myeloma (MM) who developed encephalopathy after high-dose melphalan and hematopoietic stem cell transplant (HSCT). The most common etiologies for encephalopathy such as infection, narcotic medications, metabolic-electrolyte disturbance, stroke, and central nervous system (CNS) hemorrhages were ruled out. The patient recovered from the altered mental status spontaneously. The possibilities of melphalan-induced encephalopathy versus critical-state delirium versus hypercytokinemia induce encephalopathy were contemplated.

High Dose Melphalan

Abstract Abstract 2400 Background: Approximately 10% of patients with multiple myeloma (MM) have clinically overt primary systemic light-chain (AL) amyloidosis, and about 30% have concurrent occult AL amyloidosis. The impact of concurrent AL amyloidosis on the prognosis of myeloma is not well known. High-dose melphalan followed by autologous hematopoietic stem cell transplant (auto HCT) has shown significant activity in both MM and AL amyloidosis. Methods: We performed a retrospective analysis of patients who had concurrent MM and AL amyloidosis and underwent auto HSCT with high dose Melphalan at MDACC between 01/1998 to 05/2010. We identified 41 patients with concurrent MM and AL amyloidosis. Patient characteristics are summarized in Table 1. Twenty -six patients had occult AL amyloid, while 15 had clinically overt disease. Results: Median age at auto HSCT was 56 years (39-77), 58.5% being male with median follow up of 58.7 months from the time of diagnosis and 42.5 months from auto HCT. The median time from diagnosis to auto HCT was 8.9 mos (2.7-102.4 mos). 39% had Salmon Durie Stage III disease and 36.6% had more than one involved site at the time of transplant.Cytogenetic abnormalities were detected in 24.4% of patients. Post transplant hematologic responses were as follows: ≥CR=10 (24%), ≥VGPR=16 (39%), >PR=33 (80.5%), ≥stable disease= 40 (97.6%). Among the patients with overt organ involvement, one had early death. Of the 15 evaluable patients, organ responses were scored using the published consensus guidelines for amyloidosis and were as follows: PR=5 (33.3%), ≥SD=7 (46.7%). No correlation was seen between organ response and hematologic response. The 100-day treatment related mortality (TRM) was 0 and 1-year TRM of 2.4% which is comparable to patients transplanted for MM alone at our center. The median progression-free (PFS) and overall survival (OS) from auto HCT were 33.8 and 58.3 months, respectively.The median PFS and OS from diagnosis were 49.8 and 96 mos, respectively. In multivariate analysis, creatinine ≥ 2mg/dl was associated with a shorter PFS (p=0.043) and hemoglobin <10g/dl showed a trend towards a shorter PFS (p=0.093). None of these variables (Hb <10g/dl, Age>60yrs, Creatinine≥2mg/dl, B2M >3.5mg/l, BM plasma cells>30%) emerged as significant predictors of OS. There was no significant difference in outcome between patients with occult or symptomatic AL amyloidosis for OS (p=0.24) or PFS (P=0.9) Conclusion: In this analysis the outcome of patients with concurrent MM and AL amyloidosis was comparable to patients with MM alone. We believe these patients are acceptable candidates for auto HCT.

Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0–4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.
