In oncology practice bone metastases are quite common. Of particular penchant for the defeat of the bones show breast cancer, prostate cancer, thyroid cancer, and lung and kidney. Pain is the main feature of metastatic tumors in bone. Initially, aching and casual, in the future takes persistent painful nature. This is a manifestation of tumor significantly reduces the quality of life. Treatment bisphosphonates.
They allow you to restore the mineral composition of bone and strengthen it, preventing the development of fractures. 3. Radiation therapy often can not only reduce pain but also stop tumor growth and reduce it. receive just 5% of patients outside the hospital. It is for these cases by InSightec developed a unique new system to treat tumors ExAblate focused ultrasound under the control of magnetic resonance imaging (MRI-FU). In 2004, the system ExAblate allowed for use in the Russian Federation.
Since May 2007, it is used in the Oncology Research Institute. NN Petrov in St Petersburg for the non-surgical treatment of uterine fibroids. And this year started a clinical Study on Therapy of bone metastases. This treatment is currently provided free of charge to the patient. FU-MRI procedure performed on an outpatient basis, the duration of its 1.5 -2 hours. Pronounced analgesic effect occurs within one week, and sometimes immediately after the procedure. Ultrasound heats bone, coagulate tissue periosteum adjacent to the tumor. Thus, sensory nerve endings are removed, which are the source of pain. This method of pain therapy for bone metastases may be the main treatment for patients who have not received a positive effect of irradiation. Selection of patients for Procedure 1. Men and women aged 18 years 2. Patients who are able and willing to give their consent to participate and are able to arrive at all follow-up visits to the doctor during the study. 3. Patients who suffer from symptoms associated with metastases in the bones, and are not suitable radiation therapy. 4. Tumor size less than 8 cm in diameter. 6. The tumor is visible on the MRI image and is located in the area of availability of the ultrasound beam FU-MRI. 8. Patients are able to communicate their feelings during the procedure ExAblate 9. After the chemotherapy must be at least 2 weeks 10. In the past two weeks has not been radiation therapy to kill (most painful) to be impact-FU MRI. For consultations must be MRI-study area of bone metastasis, or x-ray.
