Experiencia De Tratamiento Paliativo en Metástasis Óseas

Abstract

bone metastases and palliative radiotherapy background: About 40-50% of cancer patients have indication of palliative radiotherapy during the course of their disease. Bone metastases are the most common cause of cancer-related pain. Evidence shows that there is no statistically significant difference between long and short treatments modalities in pain relief. The aim of this study is to review the experience in treatment of patients requiring palliative radiotherapy for bone metastases treated in Clinica IRAM during 2012. methods: Descriptive retrospective analysis of medical records of patients treated during 2012 at Clínica IRAM with palliative radiotherapy for painful bone metastases. results: 197 patients were included. The median time between onset of symptoms and initiation of treatment was 4 months (1-42 months). The scheme of 8 Gy in one fraction was the most prescribed. Sixty-two percent of patients had a very good/good response to treatment, and 10% had a poor response. The median survival was 10.5 months. One, 12 and 24 months survival was 91.8%, 46.3%, 28.7% respectively. Ten patients were re-irradiated, 7 of them had received 8 Gy in a single fraction as first treatment dose. conclusion: The palliative treatment of cancer patients is an important indication of radiotherapy. The most common indication for treatment was 8 Gy/1 fraction; however, there was a 40% multi fractionated treatments. Since pain relief is similar between different treatment modalities, to offer a shorter treatment appears to be a more reasonable option.Key words: Metastases, palliative therapy, radiotherapy.resumen introducción: Aproximadamente 40-50% de los pacientes con cáncer tiene indicación de radioterapia paliativa durante el curso de su enfermedad.
