Screening for Hepatitis Virus B Protein X (HBx) in Colitis-associated Cancer (CAC)

FFPE tissue blocks from patients diagnosed with CAC, including low- and high-grade dysplasia and adenocarcinoma, obtained from pathological archives will be used. RNA will be extracted and analyzed using RT-PCR to detect and quantify HBx transcripts, with Sanger sequencing employed for further validation of the results.
