Detection of MALT1 Gene Rearrangements in BAL Fluid Cells for the Diagnosis of Pulmonary Mucosa-Associated Lymphoid Tissue Lymphoma

These results suggest that the detection of MALT1 gene rearrangements in BALF cells is useful for the diagnosis of pulmonary MALT lymphoma, as it is a specific method that is less invasive than surgical biopsy. Because of the small number of patients in this study, further investigations are necessary to evaluate the detection rate of MALT1 gene rearrangements in BALF cells from patients with pulmonary MALT lymphoma.
