Objectives
Narrative objectives1
Fluorescence in situ hybridization (FISH) plays an important role in the diagnosis of gastrointestinal lymphomas. Typically, five endoscopic biopsy specimens are collected for FISH analysis; however, the optimal number of biopsy specimens required for sufficient FISH testing has not been investigated. This study aims to establish the optimal submission method for FISH specimens from gastrointestinal mucosa.
Basic objectives2
Others
Basic objectives -Others
FISH analysis will be performed using one to four endoscopic biopsy specimens, and the results will be evaluated to determine whether they correspond to the known FISH findings previously obtained for each patient (e.g., t(11;18) positivity in MALT lymphoma, t(14;18) positivity in follicular lymphoma).
