"Complication without context? Rethinking outcome attribution in pediatric oncologic surgery"

Jain et al. explored associations between surgical complications and survival in pediatric solid tumors, concluding that higher Clavien-Dindo grades are linked to recurrence and mortality. While the study offers timely insights into perioperative risk, critical methodological limitations-including lack of multivariate adjustment, cohort heterogeneity, imprecise blood loss estimation, and omission of ERAS protocols-undermine causal interpretations. We argue that biologic factors, tumor stage, and protocol adherence are stronger predictors of survival in pediatric oncology. This letter urges a re-evaluation of attribution models and calls for prospective, tumor-specific analyses with confounder adjustment and modern surgical quality measures.
