An elderly Asian man returned from Bangladesh with an 18-month history of intermittent hiccoughs, anorexia, weight loss and fever. He had type 2 diabetes on insulin therapy with deteriorating glycaemic control. Examination revealed a thin, pale man, with intermittent hiccoughs, darkening of palmar creases and mucous membranes, angular stomatitis, oral ulceration and mild epigastric tenderness. He appeared clinically dry. He was noted to have a spiking fever to 38.5ЊC and became notably hypotensive with a blood pressure 82/35 mm/Hg during his admission. Initial investigations are shown in Table 1. Chest radiography was unremarkable and an abdominal ultrasound noted a 13.5 cm splenomegaly. There was no evidence for a subphrenic abscess.
Autologous stem cell transplantation is an established treatment that leads to prolongation in overall and disease free survival in MM. BEAM and M have been widely used as conditioning regimen for autologous stem cell transplant (ASCT) in patients with MM. At our centre MM patients with low creatinine clearance (Crcl) and a low performance status were offered Melphalan only as conditioning regime for ASCT. We report on our experience of HDM in comparison with standard BEAM. Records of 53 consecutive patients who had ASCT for myeloma at our centre between 2000 and 2003 were examined. Patients were staged as per Salmon and Durie (SD) criteria and EBMT response criteria were used for assessment post transplant .35 patients had BEAM conditioning (SD criteria 31-IIIA, 3-IA, 1-IIA) and 18(SD criteria 14- IIIA, 4-IIIB) had M.).Patients who received BEAM had a median age of 55 (range 38–66), median follow up of 19 months and those who received HDM had a median age of 60 (range 45 –69), follow up of 20.5 months. Stem cell source was peripheral blood (PBSC) in 50 patients, 1 Bone marrow (BM), and 2 BM and PBSC. HDM at a Dosage of 140 –200 mg/m2was administered in all HDM cases except for 1 patient who had 70mg/m2 because of Crcl of 17.4 ml/min. BEAM group had Carmustine 300mg/m2 (−6), Ara- C 800mg/m2 (−5 to −2), Etoposide 800mg/m2 (−5 to −2), M 140mg/m2 (−1). Patients in the M group had significantly lower haemoglobin and higher serum creatinine levels in comparison with the BEAM group. The 100-day treatment related mortality (TRM) was 5.5 % in HDM group, which was comparable to 2.2 % in the BEAM group. 9 out of 18 patients who had HDM relapsed and 9 out of 35 patients who had BEAM relapsed at follow up with Median relapse free survival (RFS) being 575 days in HDM group and has not achieved yet in BEAM group (p= .017). This data confirm that BEAM ASCT lead to significant prolongation of disease free survival with low TRM.Our data also suggest the effectiveness of HDM in patients who because of poor performance status and/or abnormal renal function may not tolerate BEAM ASCT
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
