Results: All trials compared single-fraction (8 Gy) with multiple fractions RT (20 Gy in 5 fractions or 30 Gy in 10 fractions). Pain relief efficacy was measured using the Visual Analog Scales (VAS) in two trials, the Numeric Rating Scales (NRS) in one trial, and a 4-level pain scale in another trial. The parameter of non-response rate was assessed at 1 month in three trials and at 3 months in one trial. The comparative analysis of the non-response rates between single and

multiple fractions revealed no significant difference (Relative Risk [RR] = 1.07; 95% CI: 0.68-1.68). Figure 1. Forest plot of no response rate between multiple fractions versus single fraction

Conclusion: The findings show that single-fraction RT is as effective as multi-fraction RT in pain management for BM patients also in LMICs. Given the resource constraints in LMICs, the adoption of single-fraction RT could mitigate resource utilization and expedite patient treatment timelines.

Digital Poster Healthcare professionals and smoking cessation: Knowledge, attitudes, and practices Hajer Zelaiti, Nejla Fourati, Omar Nouri, Nourdine Cheikh Mohamed Ahmed, Wicem Siala, Wafa Mnejja, Jamel Daoud Radiation Oncology, University of Sfax – Faculty of Medicine, EPS Habib Bourguiba, Sfax, Tunisia Purpose/Objective: Smoking is a major, yet preventable, risk factor for cardiovascular, respiratory, and malignant diseases. Despite national prevention campaigns, smoking prevalence remains alarmingly high in Tunisia. Healthcare professionals play a pivotal role in smoking cessation education, making their engagement essential for effective public health interventions. This study aimed to assess the knowledge, attitudes, and practices of healthcare professionals regarding smoking cessation. Material/Methods: An anonymous online survey via Google forms comprising 27 questions was distributed to the medical and paramedical staff of our department. The survey explored four domains: 1) demographic data (5 questions), 2) personal smoking history (2 questions, with 7 additional questions for smokers), 3) knowledge of smoking as a risk factor (2 questions), and 4) healthcare professionals' role in smoking cessation education (11 questions). Results: A total of 28 responses were received. The median age of participants was 37 years [26–62], with a sex ratio of 0.5. Participants included senior doctors (36%), residents (14%), technicians (29%), and nurses (21%).
