Older Age Does Not Predict Inadequate Pain Management in Cancer Patients: A Multicenter Prospective Analysis from Italian Radiotherapy Departments (ARISE-Study)

Abstract: BACKGROUND: Previous studies have often reported a link between advanced age and inadequate cancer pain management. Given Italy's demographic profile as the country with the oldest population in Europe, it offers an ideal setting to explore whether this association remains valid today. AIM: This study aimed primarily to assess the influence of advanced age on the adequacy of pain management among patients receiving treatment in Italian radiotherapy (RT) departments, and secondarily, to identify age-specific determinants of analgesic undertreatment. METHODS: = 1353) were included in the analysis. Pain management adequacy was assessed using the Pain Management Index (PMI), with negative values indicating undertreatment. A two-step statistical approach was employed: variable selection via Least Absolute Shrinkage and Selection Operator regression, followed by Classification and Regression Tree analysis to identify key predictors. Separate analyses were performed for the overall population, older adults (≥65 years), and younger adults (18-64 years). RESULTS: Overall, 42% of patients were undertreated (PMI < 0), without significant differences between older (41.0%) and younger patients (43.1%). However, factors contributing to undertreatment varied according to age. For the entire cohort, non-cancer pain was associated with substantially higher rates of undertreatment (74.3%) compared to cancer-related pain (34.2%). Among cancer patients, those receiving curative RT had poorer pain control (49.4%) than those receiving palliative RT (28.8%). In older patients, geographic location strongly influenced pain management, with higher rates of undertreatment in central and southern Italy compared to the north (e.g., palliative RT: 64.0% vs. 15.4%, respectively). Conversely, younger patients showed no geographical differences; instead, timing of assessment (beginning vs. end of RT) influenced outcomes, with improved PMI values towards the end of treatment. CONCLUSIONS: Unlike previous studies, advanced age itself was not associated with inadequate analgesia. However, the determinants of inadequate pain management differed significantly by age: geographic disparities were predominant among older patients, while assessment timing influenced outcomes for younger patients. Further longitudinal research and targeted interventions are needed to address these age-dependent challenges.
