Abstract: To the Editor, We read with great interest Yang et al.'s study [1], which reveals a survival gap that our field can no longer accept as inevitable: a 3-year overall survival of only 50.8% among children with non-gestational choriocarcinoma (PNGC), compared with cure rates exceeding 90% among adults with gestational choriocarcinoma treated with modern multimodal therapy [1,2].This disparity should not be interpreted as a biological given, but rather as evidence of a treatment and access gap that the field has yet to address.Because PNGC is rare, accounting for only 3%-5% of pediatric germ cell tumors, the existing literature is derived largely from isolated case reports.The disease's bimodal age distribution peaking in children younger than 4 years and again between 11 and 18 years further complicates efforts to establish standardized care.In the absence of disease-specific guidelines, clinicians are left to extrapolate, often awkwardly, from adult gestational trophoblastic disease protocols and general pediatric germ cell tumor regimens.By pooling four institutional cases with 70 cases drawn from 19 previously published studies, Yang et al. [1] assembled the largest cohort of PNGC reported to date.Their central finding that on multivariate analysis, single-modality therapy and no therapy at all were the only independent predictors of poor prognosis reframes the priorities of the field.It underscores the need not only for a deeper understanding of PNGC but also for treatment strategies tailored specifically to the disease.However, several aspects of the study's design and interpretation warrant closer scrutiny.The cohort assembled by Yang et al. [1] combined four institutional patients with cases drawn from previously published literature.Because published case reports and case series disproportionately describe typical or fatal presentations rather than rare or atypical ones, this approach is inherently susceptible to selection bias.As Murad et al. [3] have highlighted, case reports and case series are prone to such bias by nature, and since not every patient with PNGC is captured in the published literature, the generalizability of the pooled cohort's findings may be diminished.Future research should aim to incorporate more complete,
