Since the publication of this paper, the authors have noticed errors on pages 167 and 168 of their article. The correct sentences are shown below.

‘The major translocation cluster on BCL-1/JH consensus primer was used for MCL as reported by Andersen et al.4 Also, patient-specific clonally rearranged immunoglobulin heavy chain genes were evaluated using primer sets of Fr2A and LJH/VLJH.10 First, we performed semi-nested PCR using lymphoma cell lines with dilution series and found that maximum sensitivity of PCR was 1.0 × 10−5. Six patients could not be tested for PCR assessment owing to lack of available primary samples. Four patients were excluded because of negative results of PCR analysis for primary samples. Finally, PCR analysis was performed in a total of 20 patients (Table 2). Fourteen FL patients had the detectable MBR/JH rearrangement and five MCL patients could be evaluated using primer sets of immunoglobulin heavy chain rearrangement. Three MCL patients had the t(11;14) breakpoints detected by PCR, two of which could be evaluated with both the t(11;14) breakpoints and immunoglobulin heavy chain rearrangement.’
