术中自体血回输用于肿瘤患者的研究进展

术中自体血回输目前已广泛应用于各类手术患者的围术期血液保护。对于肿瘤患者，术中回收的自体血中可能存在循环肿瘤细胞，应用自体血回输具有潜在的肿瘤复发、转移的风险。因此，术中自体血回输能否用于肿瘤患者尚存争议。本文主要从术中自体血回输的应用现状、术中自体血回输在肿瘤患者手术中的应用、术中自体血回输对肿瘤患者预后的影响等方面进行综述，为肿瘤患者术中使用自体血回输提供参考。

Advances in the use of intraoperative cell salvage in tumor patients

Intraoperative cell salvage has been widely used in the perioperative blood conservation of various surgeries. Tumor patients may have circulating tumor cells in the autologous blood salvaged during surgery, which may potentially cause recurrence and metastasis. Therefore, whether intraoperative cell salvage can be used in tumor patients is controversial. This review mainly focuses on the application status of intraoperative cell salvage, the application of intraoperative cell salvage in surgery of tumor patients and the impact of intraoperative cell salvage on the prognosis of tumor patients. It is expected that this review will provide a reference for the use of intraoperative cell salvage in tumor patients.
