In addition, B-cell monoclonality was analyzed for immunoglobulin heavy chain (IgH) gene rearrangement using the polymerase chain reaction at the site of the lymphoma lesion, transitional lesion, and the non-lymphoma lesion. Specimens resected from 31 primary gastric lymphomas were examined. There were 28 cases (90.3%) of B-cell lymphoma and three cases (9.7%) of T-cell lymphoma. The B-cell lymphomas were classified as low-grade mucosa-associated lymphoid tissue (MALT) lymphoma (LGML) (9%), high-grade MALT lymphoma (HGML) (42%), and diffuse large B-cell lymphoma (DLBCL) (29%). Histopathologically, lymphoepithelial lesions (LEL) were higher in LGML (100%) than in DLBCL (22%), with statistical significance (p < 0.05). A monoclonal pattern of IgH rearrangement was detected in LGML (50.0%), HGML (60.0%), and DLBCL (80.6%), with a statistically significant difference between LGML and DLBCL (p < 0.01). The IgH monoclonal pattern may reflect the gross appearance of lymphoma or the lymphoma infiltration depth. Superficial spreading and shallow growth in LGML may correspond to an oligoclonal pattern, and mass-forming and deep invasive growth in DLBCL may correspond to a more monoclonal pattern.","is_dataset_classified":null,"base_score":1.9459101490553132,"endowment":1.9459101490553132,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"14666967","pmcid":null,"openalex_id":"https://openalex.org/W2084703359","authors":[],"funders":[],"total_grants":0,"fwci":0.1994,"citation_percentile":0.58440053,"influential_citations":0,"citation_trend":[{"year":2014,"count":1},{"year":2015,"count":1},{"year":2016,"count":1},{"year":2024,"count":1},{"year":2025,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0344033804704744?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0344033804704744?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1078/0344-0338-00476","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/14666967","host_type":"repository"},{"url":"https://saga-u.repo.nii.ac.jp/records/13493","host_type":"repository"}],"fields_of_study":["Lymphoma Diagnosis and Treatment","Gastrointestinal Tumor Research and Treatment","Viral-associated cancers and disorders","Adult","Aged","Aged, 80 and over","Biomarkers, Tumor","Clone Cells","DNA, Neoplasm","Female","Gene Rearrangement","Humans","Immunoenzyme Techniques","Immunoglobulin Heavy Chains","Lymphoma, B-Cell","Lymphoma, T-Cell","Male","Middle Aged","Polymerase Chain Reaction","Stomach Neoplasms"],"mesh_terms":["Adult","Aged","Aged, 80 and over","Clone Cells","DNA, Neoplasm","Female","Humans","Immunoenzyme Techniques","Immunoglobulin Heavy Chains","Male","Middle Aged","Stomach Neoplasms","Biomarkers, Tumor","Gene Rearrangement","Polymerase Chain Reaction","Lymphoma, B-Cell","Lymphoma, T-Cell"],"keywords":["Lymphoma","MALT lymphoma","Pathology","Immunoglobulin heavy chain","Gene rearrangement","Gastric lymphoma","Monoclonal","Immunoglobulin light chain","Large-cell lymphoma","B cell","B-cell lymphoma","Diffuse large B-cell lymphoma","Biology","Lymphatic system","Mucosa-associated lymphoid tissue","Lesion","Antibody","Monoclonal antibody","Medicine","Immunology","Gene"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life below water"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-04T17:53:49.901153Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
