title: External beam irradiation in the palliation of bone metastases: a practice analysis among Sicilian Departments of Radiation Oncology.
abstract: BACKGROUND
  In the treatment of bone metastases, the choice of radiation fractionation, total radiation dose, delivery technique, and imaging studies before treatment varies among radiation oncologists. Surveys on this issue, using case scenarios, have been published by groups from Europe, North America, and Australia-New Zealand. Our objective was to analyze retrospectively the "real" practice in nine radiotherapy centers located in Sicily.
  
  
  METHODS
  A questionnaire including 17 items was distributed to 30 practicing radiation oncologists working in seven departments of four Sicilian cities (Messina, Catania, Ragusa and Palermo) during a meeting of the Sicilian Division of the Associazione Italiana Radioterapia Oncologica (AIRO). Participants were asked to answer the questions using a card for every patient treated with external beam irradiation from 1 January to 31 December, 2000.
  
  
  RESULTS
  Six centers returned the questionnaires; 332 cards were valuable for a total of 5644 responses. All six responding departments used linear accelerators for treatment delivery. The most common dose fractionation was 30 Gy in 10 fractions and the most common technique used was opposed parallel local fields. Before the start of irradiation a bone scan was performed in 325 of the 332 (98%) patients treated and CT and/or MRI was performed in 320 (96%); surprisingly, standard roentgenograms were used in only 142 of 332 patients (42.8%).
  
  
  CONCLUSIONS
  The "real" radiation practice for bone metastases in the region of Sicily confirms the results of the previously reported international surveys: there is a clear preference for fractionated treatment and local field therapy. The results of randomized studies, which demonstrated both the efficacy and the feasibility of a single 6-8 Gy fraction in the palliation of bone metastases, have little or no impact on the pattern of practice.
