Chinese Multicenter Registry for Peutz-Jeghers Syndrome

Brief summary (registry, in English)

This prospective, observational patient registry will enroll approximately 1,000 individuals with a clinical or molecular diagnosis of Peutz-Jeghers syndrome (PJS) at participating hospitals in China. The registry will collect standardized clinical information, existing genetic test reports, family history, and longitudinal outcomes. The primary objective is to estimate the 10-year cumulative incidence of a first invasive malignancy after enrollment among participants without a previous malignancy or an unresolved suspected malignancy at baseline, accounting for death as a competing event. Secondary objectives address organ-specific malignancies, new primary cancers in participants with a cancer history, mortality, major polyp-related complications, and clinical and STK11 variant characteristics. Participants may be followed for up to 20 years. Biospecimen donation, additional baseline sampling, research sequencing, and patient-derived organoid studies are optional and require the corresponding consent. Refusal of an optional component does not preclude participation in the clinical registry. No treatment or clinical surveillance strategy is assigned by the study.
