Abstract excerpt
PURPOSE: Individuals affected by rheumatoid arthritis (RA) occasionally develop lymphoproliferative disorders (RA-LPD). To study the molecular changes underscoring the RA-LPD, mutations of p53 and Bak gene were analyzed in RA-LPD with (MTX-LPD) or without methotrexate treatment for RA (non-MTX-LPD). METHODS: Histology and immunophenotype were immunohistochemically examined in 32 cases of MTX-LPD and 21 of...
