The Glasgow Prognostic Score as a pre-transplant risk assessment for allogeneic hematopoietic cell transplantation.

Evaluation methods, such as scoring systems for predicting complications in advance, are necessary for determining the adaptation of allogeneic hematopoietic cell transplantation (HCT) and selecting appropriate conditioning regimens. The Hematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI), which is based on functions of main organs, is a useful tool for pre-transplant risk assessments and has been widely applied in determining treatment strategies for patients with hematological diseases. However, as allogeneic HCT is performed on patients with diverse backgrounds, another factor, which reinforces the HCT-CI, is required to evaluate pre-transplant risk assessments. The Glasgow Prognostic Score (GPS), which assesses the combined C-reactive protein and albumin, was reported to predict survival of patients with solid-organ malignancies independently of receiving chemo/radiotherapy and stages of cancer. In this study, we applied the GPS for pre-transplant risk assessments for allogeneic HCT. The GPS successfully stratified the patients into three risk groups of overall survival (OS) and non-relapse mortality (NRM). Moreover, the GPS could predict outcomes independently of the HCT-CI for OS and NRM in multivariate analysis. The GPS is considered to be a useful tool and reinforces the HCT-CI for determining adaptation of allogeneic HCT for patients with hematopoietic neoplasms.
