We have designed a multiplex PCR, which allows for fast and high throughput demonstration of the BCL-1/IGH and BCL-2/IGH fusion DNA observed primarily in mantle cell- and follicular non-Hodgkin's lymphoma (NHL). Blood (PB) and/or bone marrow (BM) from 258 patients suspected of NHL have prospectively been evaluated. Eleven patients (4%) were found t(11;14)+ and 37 patients (14%) t(14;18)+. Comparing these results to standard diagnostic methods of PB and/or BM identified PCR+ samples that were normal by morphology (BCL-1/IGH: 1/11; BCL-2/IGH: 17/37). Equally important, patients who were not clonal in PB and/or BM by flow cytometry were identified as PCR+ (BCL-1/IGH: 3/11; BCL-2/IGH: 23/37). We conclude that this multiplex approach allows for easy and sensitive molecular determination of molecular lesions in NHL, which have diagnostic and prognostic importance.
