chemotherapy. Mean prescribed dose 52 Gy (25–76); all prostate patients received androgen-deprivation therapy. Patient understanding improved: mean score for “I understood how to prepare for radiotherapy” increased from 6 to 9 (p<0.001).Difficulty holding the bladder increased from 5 to 7 (p=0.02) consistent with the development of irritative urinary symptoms during treatment. Preparation-related anxiety remained stable around 6 (p=0.41). General anxiety (PHQ-4 ≥ 3) decreased from 60% to 47% (p=0.04); depressive symptoms remained low (34% vs 33%, p=0.89). In the prostate subgroup, 33% reported urgent or positive bowel movements during treatment, generally rated as moderate in severity. Multivariable analysis: older age was associated with lower understanding (p=0.009) and greater bladder difficulty (p<0.01); prior pelvic surgery increased difficulty, especially at RT end (p=0.05). Concurrent chemotherapy showed no significant association. Conclusion: Patients generally gain understanding of pelvic radiotherapy preparation over time, but bladder filling remains challenging for older patients and those with prior pelvic surgery, highlighting the importance of tailored support.

The study primary aim was to quantify the distribution and change in pain scores using the Numeric Rating Scale (NRS) [1], providing insight into the effectiveness of RT in alleviating metastatic pain. Material/Methods: Patients referred for palliative RT with prescribed doses of 8, 16, or 20 Gy for painful bone metastases were prospectively evaluated. Pain intensity at the irradiated site was self-reported using an 11-point Numerical Rating Scale (NRS; 0/1 = no pain, 10 = worst imaginable pain) prior to RT and at six weeks post- treatment. Data were collected from structured clinical follow-up forms. Descriptive statistics were used to Digital Poster 4185

The hidden challenge of pelvic radiotherapy: When bladder filling and rectal emptying meet patient anxiety Ghada Abdessatar, Farah Benaissa, Siwar Abdessaied, Mouna Ben Rejeb, Lotfi Kochbati Radiation Oncology, Abderahmane Mami Hospital, Ariana, Tunisia Purpose/Objective: Pelvic irradiation requires specific patient preparation, including an optimally filled bladder and an empty rectum, to ensure reproducible target volume positioning and optimal sparing of organs at risk. Although this preparation may appear simple in theory, it can be difficult for patients to achieve and maintain consistently, particularly in complex clinical and psychological contexts.The objective of this study was to evaluate patients’ experience of pelvic radiotherapy preparation in terms of understanding, perceived difficulty, anxiety, and perceived effectiveness at the beginning and at the end of treatment, and to identify clinical factors influencing this evolution. Material/Methods: This prospective observational study was conducted at Abderrahmane Mami Hospital among patients receiving pelvic radiotherapy for gynecologic, prostate, or rectal cancers requiring specific preparation. Patients completed a 7-item self-administered questionnaire before the first and after the last fraction of radiotherapy (7-point Likert scale) assessing understanding, preparation-related anxiety, and preparation difficulty. Anxiety and depression were assessed using the validated Arabic version of the PHQ-4 (score range 0–12), categorized as normal (0–2), mild (3–5), moderate (6–8), and severe (9–12); scores ≥ 3 indicated the presence of anxiety or depression. The EPIC questionnaire was additionally used for patients with prostate cancer. All participants provided oral informed consent. Results: A total of 76 patients were included (152 questionnaires). Tumor sites: cervix 18% (n=14), endometrium 42% (n=32), rectum 29% (n=22), prostate 11% (n=8). Mean age 62 years (28–87); 51% had prior pelvic surgery, 58% received concurrent
