Abstract
Background: Blood loss is an important consideration in metastatic spine tumour surgery (MSTS). Allogeneic blood transfusion (ABT) is the current standard of blood replenishment for MSTS despite known complications. Salvaged blood transfusion (SBT) through intraoperative cell salvage addresses the majority of complications related to ABT. However, the use of SBT in MSTS still remains controversial. We aim to conduct a prospective propensity-score (PS) matched analysis to evaluate the long-term clinical outcomes of intraoperative cell salvage (IOCS) in MSTS.
Methods: Our study included 98 patients who underwent MSTS from 2014-2017. A PS matched cohort was created using the relevant and available predictors of treatment assignment and outcomes of interest. Clinical outcomes consisting of overall survival (OS), as well tumour progression (TP) that was evaluated using RECIST (v1.1) were compared in the matched cohort.
Results: Our study had a total of 98 patients with a mean age of 60 years old. A total of 33 patients received SBT. Overall median blood loss was 600 mL [interquartile range (IQR): 300-1,000 mL] and overall median blood transfusion (BT) was 620 mL (IQR: 110-1,600 mL). Group PS matching included 30 patients who received ABT and 28 patients who received SBT. There was also no significant difference between the OS of patients who underwent ABT or SBT (P=0.19). SBT did not show any significant increase in 4-year tumour progression [PS matched hazard ratio (HR) 3.659; 95% confidence interval (CI): 0.346-38.7; P=0.28].
Conclusions: SBT has been shown to have similar clinical outcomes to that of ABT in patients undergoing MSTS, with potential benefits of avoiding complications and costs of ABT. This will be the first long-term PS matched analysis to report on the clinical outcomes of SBT and affirms the clinical role of SBT in MSTS today.

The Chinese Clinical Oncology (Print ISSN 2304-3865; Online ISSN 2304-3873; Chin Clin Oncol; CCO) publishes articles that describe new findings in the field of oncology, and provides current and practical information on diagnosis, prevention and clinical investigations of cancer. Specific areas of interest include, but are not limited to: multimodality therapy, biomarkers, imaging, tumor biology, pathology, chemoprevention, and technical advances related to cancer. The aim of the Journal is to provide a forum for the dissemination of original research articles as well as review articles in all areas related to cancer. It is an international, peer-reviewed journal with a focus on cutting-edge findings in this rapidly changing field. To that end, Chin Clin Oncol is dedicated to translating the latest research developments into best multimodality practice. The journal features a distinguished editorial board, which brings together a team of highly experienced specialists in cancer treatment and research. The diverse experience of the board members allows our editorial panel to lend their expertise to a broad spectrum of cancer subjects.
