The log-rank method was used to compare the effects of sex, age, location, KPS score, spinal segment, primary tumor growth, organ metastasis, and surgical method on the survival rate of patients. Survival curves of the survival rates are shown in Table Survival time for 62 cases of lumbosacral vertebral osteoblastic metastasisKaplan–Meier analysis and the log-rank test comparing the influence of factors, such as sex, age, tumor metastases, viscera metastasis, KPS score, spine transfer section, and primary tumor growth, surgical approach on patients’ survivalThe results showed that there was no significant difference in the survival rate between male and female patients with lumbosacral osteoblastic metastases (The survival rate of patients with a preoperative KPS score of 60–70 was significantly lower than that of patients with a score of 80–100 (To determine the effects of different surgical methods on the progression-free survival rate of patients with lumbosacral osteoblastic metastases, we used the Kaplan–Meier log-rank method for comparison. The survival curves comparing the different surgical modalities are shown in Fig.
