Prognostic Significance of Hypoalbuminemia in Patients with Relapsed/Refractory Hodgkin’s Lymphoma (R/R-HL) Undergoing Salvage Autologous Bone Marrow/Peripheral Stem Cell Transplantation (auto-BM/PSCT).

Background : Management of R/R-HL has been disappointing with salvage chemotherapy alone. Although controversy remains over the best time to perform a transplant, auto-BM/PSCT is considered an acceptable salvage therapeutic option for patients (pts) with R/R-HL. Hypoalbuminemia is one of the seven adverse prognostic factors for newly diagnosed pts with HL who receive chemotherapy according to the international prognostic factors project on advanced HL. The prognostic significance of hypoalbuminemia in pts with R/R-HL undergoing salvage auto-BM/PSCT is less clearly defined at the present time. Objective: To evaluate the prognostic significance of hypoalbuminemia in pts with R/R-HL who undergo salvage auto-BM/PSCT. Methods: A retrospective, single-institution study of consecutive pts with R/R-HL who received auto-BM/PSCT at the University of Oklahoma over the last 19 years (1985– 2004) was performed. The serum albumin level during hospital admission for transplant that was closest to, but before, high-dose chemotherapy was recorded and used for this analysis. Hypoalbuminemia was defined as a serum albumin level ® sofware (version 8.0; Carry, NC) was used for statistical analysis. Results: 66 patients (40 males, 26 females) were identified, who were 13–69 years old (median 29 years) at the time of transplant. 40 pts (61%) died during follow-up, 4 pts (6%) were lost to follow-up at 15, 27, 58 and 103 months after transplant, and 22 pts (33%) are alive at the time of this analysis (7/30/04), 2–187 months (median 68 months) after transplant. Median survival for the control group (n 1 =27, 13/27 died) was 78 months (95% CI: 23 - N/A months) and for the low-albumin group (n 2 =39, 27/39 died) was 22 months (95% CI: 13– 44 months). The difference between overall survival curves (figure) and also the difference between median survivals approached, but did not reach statistical significance (p-values for log-rank and Wilcoxon-Mann-Whitney tests, 0.0632 and 0.0565, respectively). Conclusion: Our results suggest a trend for a worse outcome among pts who undergo salvage auto-BM/PSCT for R/R-HL with low serum albumin (
