About this trial
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.
Eligibility criteria
Qualifiers
Patients with histologically confirmed appendiceal adenocarcinoma or appendiceal cancer.
Availability of archived tumor tissue suitable for molecular profiling.

Disqualifiers
Insufficient tissue quantity or quality for molecular profiling.
Inadequate DNA or RNA quality for sequencing or molecular assay preparation.
Missing essential clinicopathologic information required for analysis.
Non-appendiceal primary tumor or metastatic tumor to the appendix from another primary site.
