\title{TCGA-STAD Clinical and Molecular Annotation Data}
\format{
A data frame with samples as rows and variables as columns:
\itemize{
  \item ID – TCGA sample barcode
  \item stage – tumor stage (Stage_I, Stage_II, etc.)
  \item status – vital status (Alive/Dead)
  \item Lauren – histological classification
  \item subtype – molecular subtype (EBV, MSI, GS, CN, ...)
  \item EBV – EBV infection status
  \item TMEscore_plus – continuous tumor-micro-environment score
  \item TMEscore_plus_binary – High/Low TME classification
  \item time – follow-up time (months)
  \item OS_status – 0 = alive, 1 = dead
  \item ARID1A, PIK3CA – driver-gene mutation status
  \item MALAT1 – lncRNA expression
  \item remaining columns – gene-expression values and additional
  clinical/molecular annotations
