Abstract:Bone metastases represent an important complication of malignant tumours. Despite improvement in surgical techniques and advances in systemic therapies, management of patients with bone metastatic disease remains a powerful cornerstone for the radiation oncologist. The primary goal of radiation therapy is to provide pain relief, preserving patients quality of life.
“…Radiation therapy induced edema, necrosis, dystrophic calcifications within tumor, decreased inflammatory response and osteoclast activity. However patients will experience complete to partial pain relief, typically within 4 weeks after RT [17]. Vertebroplasty compare to RT offer immediately anterior column support and restore spine stability [18,19].…”
Introduction. The pathological vertebral compression fracture (VCF) in course of cancer range from 5 to 39% among oncological patients. Main symptom is a back pain, that is refractory to medical therapy. Treatment of stable pathological VCF include radiotherapy, bisphosphonate medication and bracing. Nonoperative modalities are effective in pain management. However their results are delayed or require immobilization of patient. Additional they influence on the spine stability is small. Instabile VCF led to progressive kyphotic deformation, that reduce lung capacity, physical and social function of patient and decreased quality of life. Vertebroplasty (VP) is mini-invasive surgical technique of the vertebral body augmentation with methyl methacrylate. The first percutaneous vertebroplasty was performed in 1984 be Galibert since then VP prove to be effective in treatment of VCF. Material and methods. Retrospective analysis of 72 patients with solid tumor metastasis and myeloma multiplex which underwent VP in the Oncological Orthopedic Department of the Podkarpackie Oncological Center were made. Patients were operated since 2015 to 2016. Mean age of study population were 60.4 ± 12.6 years. The amount of cement which was injected was 3.98 ± 1.5 ml. The procedure last on average 22 ± 5 minute. The most common primary tumor type was breast cancer and myeloma multiplex. Results. Over 100 levels in 72 patients were stabilized with VP. In 69% one level was augmented. Mean VAS reduction was 3.98 ± 1.56 point and Karnofsky score increase of 11.2 ± 4.3 point. Effectiveness of VP was independent from site of primary tumor, Tomita score, localization, and number of metastasis, and amount of injected cement. Patients with myeloma multiplex had smaller reduction of VAS compare to solid tumor group and require additional procedure at different level. In postoperative period in 42% case asymptomatic cement leakage occur. In one case (1.4%) leakage to the spinal canal was noted and laminotomy was required. Conclusions. Vertebroplasty is effective noninvasive technique for pain reduction in patients with pathological compression fracture of the vertebral body. Patients with myeloma multiplex had lower VAS reduction and are more likely to need second VP at different level. The most common complication is cement leakage which is asymptomatic.

“…[1,14] Majority of patients with bone metastasis requires an urgent treatment, due to pain, pathological fractures, spinal cord compression, hypercalcaemia and neurologic deficits. [15] Therefore, the aim of palliative RT is to provide complete pain relief, recalcification and stabilisation of the bone, reduction in the risk of complications (e.g. bone fractures, spinal cord compression) and reduce analgesic requirements.…”

“…Complete to partial pain relief is said to occur within 4 weeks after RT with a mean duration of remission in 19 weeks. [15] Keeping this in mind, we re-assessed pain scores after 3 months of RT.…”
BACKGROUNDRadiation therapy plays an important role in the treatment of breast cancer patients with bone metastasis. Approximately 70% of patients are likely to achieve complete pain relief after palliative external beam radiotherapy (RT). The aim of current study is to determine the role of RT in palliation of symptomatic bone metastases from invasive breast cancer.
“…Radyasyon tedavisi etkinliğini, direkt olarak DNA'da hasar yaratarak, indirekt olarak ise çeşitli serbest radikaller oluşturup bunlar üzerinden hücre DNA hasarı yaparak gösterir. [5] Klinik radyoterapi uygulaması üç şekilde olur: 1) Eksternal ışıma radyasyonu (konvansiyonel X ışını kullanılarak yapılan radyoterapi) 2) Brakiterapi 3) Radyonükleotid tedavisi Kemik metastazı olan hastalara uygulanan radyoterapinin hedefi; hastanın hayat kalitesini arttırmak, iskelet fonksiyonlarının devamını sağlamak, ağrı kesici kullanımını azaltmak ve mümkünse ortadan kaldırmaktır. Bunları başarmak için; tümörün ilerlemesini, patolojik kırık oluşumunu ve spinal kord basısını engellemek ya da ortadan kaldırmak gerekir.…”

“…Her bir fraksiyonda yüksek doz, yani 10 Gy'den fazla enerjinin hedef noktada birleştirilerek uygulanmasıyla, tümör hücrelerindeki DNA hasarının yanı sıra tümör vaskülaritesindeki azalma için direkt etki sağlanmış olur. [5] Stereotaktik radyoterapi endikasyonları arasında; vertebra gövde lezyonları, lezyon çapının 5 cm'den az olması, semptomatik spinal kord basısının bulunmaması ve hedef radyoterapi hacminde en fazla üç vertebra bulunması yer alır. Semptomatik spinal kord basısı varsa, stereotaktik radyoterapi ancak cerrahi olarak dekompresyon yapıldıktan sonra verilebilir; çünkü, spinal kordu hedef alan stereotaktik radyoterapide, geri dönüşümsüz miyelopati ve sinir arazı riski vardır.…”
