Objective: Bone is one of the most vulnerable sites for tumor metastasis, and 50% of malignant tumor patients will eventually develop bone metastasis of tumor, among which, some of them metastasize to the pelvis, which leads to a series of complications and seriously affects the survival quality of patients and even endangers their lives. The choice of treatment for metastatic bone tumors in the pelvis mainly depends on the life expectancy of the patients, and the goal of treatment is to improve the quality of survival, control local symptoms and treat the underlying lesions, and prolong their survival time as much as possible. Methods: At present, the intervention methods for metastatic pelvic tumors include: pharmacological interventions, such as chemotherapy drugs, endocrine therapy and targeted therapy drugs for controlling primary tumors, bisphosphonates, drugs for controlling and relieving tumor pain, etc.; radiotherapy for primary tumors or metastatic pelvic tumors; immunotherapy; simulation of the scope of radiofrequency and surgery according to the images of CT and MRI, CT-guided The design and fabrication of individualized hemi-pelvic prosthesis was completed based on the tumor boundary designed by CT and MRI images, complete surgical resection of pelvic tumor and individualized hemi-pelvic installation to control or relieve pain and restore basic weight-bearing function; psychological and limb rehabilitation, etc. We reviewed 10 patients with metastatic bone tumors in the pelvis with complete follow-up in the past 2 years, aged 35-80 years, 7 men and 3 women. Based on the comprehensive assessment of patients’ age, type of primary tumor, type and site and extent of metastatic tumor involving the pelvis, physical condition, patients’ treatment expectation and willingness, and treatment cost, 5 cases were operated on the basis of comprehensive treatment, among which, 2 cases in zone I+II+III+IV, 2 cases in zone I+II+III, and 1 case in zone III, the first 4 cases underwent hemipelvic prosthesis reconstruction; 2 cases underwent CT-guided Minimally invasive radiofrequency surgery was performed in 2 cases; 3 cases underwent pharmacological treatment and palliative treatment for the primary tumor. RESULTS: There were no deaths in all 10 patients, and the five operated patients had better pain and functional and quality-of-life scores than the non-operated patients. CONCLUSION: Based on the assessment of the results of the follow-up, we concluded that metastatic bone tumors in the pelvis pose a serious risk to the quality of life of patients and should be actively intervened, but the selection of the treatment plan should be evaluated comprehensively and strictly follow the principle of individualization in order to achieve satisfactory results.
