Symptomatic spinal metastasis: A systematic literature review of the preoperative prognostic factors for survival neurological functional and quality of life in surgically treated patients and methodological recommendations for prognostic studies

摘要

PurposeWhile several clinical prediction rules (CPRs) of survival exist for patients with symptomatic spinal metastasis (SSM), these have variable prognostic ability and there is no recognized CPR for health related quality of life (HRQoL). We undertook a critical appraisal of the literature to identify key preoperative prognostic factors of clinical outcomes in patients with SSM who were treated surgically. The results of this study could be used to modify existing or develop new CPRs.
