摘要

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.
