Bone Metastases - Pathophysiology, Diagnostic Testing and Therapy (Part 2).

The second part of this review deals with the several options for the surgical therapy of bone metastases according to their anatomical site and the patient's individual prognosis. Although metastases to the bone - with few exceptions - are normally given palliative therapy, patients nowadays reach survival times of several months to years, depending on the underlying tumour entity. Scoring systems are suitable to estimate the patient's prognosis and fracture risk. The indication for operation has to be adapted to these parameters. In order to preserve a high quality of life, a limb saving procedure has to be aimed at. The options include the resection of the metastasis with stabilisation, the sole stabilisation of the affected bone, and wide resection with limb reconstruction using a modular tumor endoprosthesis. With today's anaesthesiological peri- and intraoperative care, a vast number of surgical implants and bone augmentations are available. However, what is important is not the practicability of the procedure, but the oncological justification and patient-adapted selection of surgical therapy.
