JIANG Liang, E-mail: jiangliang@bjmu.edu.cn; LIU Zhong-jun, E-mail: zjliu@bjmu.edu.cn This work was supported by the Research Grant of Peking University Third Hospital (Y71508-01) [Abstract] Objective To observe the perioperative complications for metastatic cervical tumor, and explore their possible risk factors. Methods From January 2012 to January 2016, 57 patients undergoing surgery for cervical spine metastasis were retrospectively analyzed, who were followed-up for at least 12 months or until death. Data collected included pain (a 10-point visual analogue scale, VAS), Karnofsky performance status score, neurologic status according to Frankel scale, perioperative complications, postoperative mortality and so on. Results The VAS score decreased significantly postoperation (P<0.001). The Frankel grade was significantly improved (P=0.025). The Karnofsky score was also significantly improved (P<0.001). The rate of local recurrence was 12.3%. Perioperative mortality rate (30 days after surgery) was 3.5%. Perioperative complication incidence was 24.6%. Univariate analysis found that comorbidity, preoperative Karnofsky score <60, multisegmental resection, and intraoperative blood loss >300ml were significant risk factors for the complication. Multivariable analysis showed that iintraoperative blood loss >300ml and preoperative Karnofsky score <60 were the independent predictors for the complication. Conclusions Surgical management for cervical spinal metastasis is effective in terms of neurological recovery, pain control, and performance status recovery. However, the surgery had a high risk of complications that special attention should be paid to. Furthermore, complications might be related to preoperative Karnofsky score and intraoperative blood loss.
