Peer Review in Radiation Oncology: Where Does the Middle East, North Africa, and Türkiye Region Stand?

PURPOSE: This study aims to assess the status of radiation oncology peer review procedures across the Middle East, North Africa, and Türkiye (MENAT) region. METHODS: A cross-sectional electronic survey was conducted among radiotherapy centers in the MENAT region in March 2024. It assessed peer review practices, departmental demographics, perceived importance of peer review, and potential barriers. RESULTS: Data from 177 radiation oncology centers revealed varying peer review implementation across the MENAT region. Egypt had the highest participation (16.4%) among all responders. Most centers (31%) treated 500-1,000 cases annually. The majority (77.4%) implemented peer review, with varying levels between countries and across different centers. Advanced radiotherapy techniques significantly correlated with implementation of peer review (P < .05). Peer review meetings were mostly scheduled on a weekly basis (46%) and organized by radiation oncologists (84.7%). Target volume contouring (89%) and radiotherapy prescription (82%) were frequently peer-reviewed. Respondents with peer review at their institutions significantly valued peer review for education, adherence to guidelines, improving planning protocols, and reducing variation in practice institutions without peer review (P < .05). The most frequently reported barriers to peer review were having a high number of patients (56%) and shortage of time (54%). CONCLUSION: Peer review is essential for improving the quality of practice in radiation oncology. Despite some discrepancies, numerous obstacles, and challenges in implementation, it is instrumental in the improvement of patient care in most centers throughout the region. Raising awareness among radiation oncologists about the importance of peer review is paramount to lead to better outcomes.

Life-Threatening Event Risk in Children With Wolff-Parkinson-White Syndrome: A Multicenter International Study.

OBJECTIVES: This study sought to characterize risk in children with Wolff-Parkinson-White (WPW) syndrome by comparing those who had experienced a life-threatening event (LTE) with a control population. BACKGROUND: Children with WPW syndrome are at risk of sudden death. METHODS: This retrospective multicenter pediatric study identified 912 subjects ≤21 years of age with WPW syndrome, using electrophysiology (EPS) studies. Case subjects had a history of LTE: sudden death, aborted sudden death, or atrial fibrillation (shortest pre-excited RR interval in atrial fibrillation [SPERRI] of ≤250 ms or with hemodynamic compromise); whereas subjects did not. We compared clinical and EPS data between cases and subjects. RESULTS: Case subjects (n = 96) were older and less likely than subjects (n = 816) to have symptoms or documented tachycardia. Mean age at LTE was 14.1 ± 3.9 years of age. The LTE was the sentinel symptom in 65%, consisting of rapidly conducted pre-excited atrial fibrillation (49%), aborted sudden death (45%), and sudden death (6%). Three risk components were considered at EPS: SPERRI, accessory pathway effective refractory period (APERP), and shortest paced cycle length with pre-excitation during atrial pacing (SPPCL), and all were shorter in cases than in control subjects. In multivariate analysis, risk factors for LTE included male sex, Ebstein malformation, rapid anterograde conduction (APERP, SPERRI, or SPPCL ≤250 ms), multiple pathways, and inducible atrial fibrillation. Of case subjects, 60 of 86 (69%) had ≥2 EPS risk stratification components performed; 22 of 60 (37%) did not have EPS-determined high-risk characteristics, and 15 of 60 (25%) had neither concerning pathway characteristics nor inducible atrioventricular reciprocating tachycardia. CONCLUSIONS: Young patients may experience LTE from WPW syndrome without prior symptoms or markers of high-risk on EPS.
