Bone tissue is the third most common tissue for metastasis after lung and liver. Pelvis is the most common site of metastatic bone after vertebral column. The aim of treatment of lesions in these locations is to reduce the pain of the patient, to overcome immobility, and provide lower extremity functions. In the treatment of these lesions, a multidisciplinary team consisting of an orthopedic surgeon, a medical oncologist, a radiation oncologist, and an interventional radiologist should be formed, taking into account the general condition of the patient. Many surgical methods including curettage, cementation, resection, various arthroplasty applications and hemipelvectomies; non-surgical procedures such as radiotherapy; minimally invasive procedures such as radiofrequency ablation, cryoablation, percutaneous cement applications are available. In this review article, we aimed to present the current classifications and treatment methods used in the management of pelvic metastatic lesions. The general condition of the patient, response of the primary disease to neoadjuvant therapies, expected survival times, number and location of lesions; all are important in treatment planning. It is possible to prevent under or over treatment arrangements in the treatment planning of patients with limited life expectancies by using the classification systems mentioned in this review.
