Conditions
Summary
This study investigates integrated epigenetic and epitranscriptomic features of appendiceal cancer using archived tumor tissue specimens from the same patient cohort. The study includes DNA methylation profiling and m6A epitranscriptomic profiling to define molecular subtypes, evaluate associations with clinicopathologic features, and develop molecular risk scores for prognostic stratification. The primary goal is to determine whether DNA methylation- and m6A-based molecular features can complement conventional histopathologic grading and improve risk stratification.

Interventions
Archived tissue specimens undergo DNA methylation profiling to characterize tumor-associated methylation alterations and identify methylation-based molecular features associated with clinicopathologic variables and survival outcomes. The profiling is performed for research purposes only and does not assign treatment.
Archived tissue specimens undergo m6A methylated RNA immunoprecipitation sequencing with matched input RNA sequencing to quantify transcriptome-wide m6A enrichment. The resulting molecular data are used for subtype discovery, m6A score construction, reduced-panel development, and association with clinicopathologic and survival outcomes.
