| Outline of Final Research Achievements |
We have detected MALT1, IgH and TRB rearrangements in bronchoalveolar lavage fluid and investigated the utility for the diagnosis of pulmonary lymphomas.The sensitivity and false positive rate of MALT1 gene rearrangements for mucosa associated lymphoid tissue (MALT) lymphoma was 60 and 0 %, respectively. The sensitivity of IgH gene rearrangements for MALT lymphoma and other B cell lymphomas was 90 and 88 %, respectively. TRB gene rearrangements were positive in many cases of non-lymphomas (57%).
These results suggest that detection of MALT1 and IgH gene rearrangements in bronchoalveolar lavage fluid are useful for the diagnosis of lung lymphomas.
