Abstract Somatic hypermutations (SHMs) in the variable region (VH) of the immunoglobulin heavy chain (IgH) gene are common in diffuse large B‐cell lymphoma (DLBCL). Recently, IgH VH SHMs have become known as immunogenic neoantigens, but few studies have evaluated the prognostic impact of the frequency of VH SHMs in DLBCL. The BIOMED‐2 protocol is the gold standard polymerase chain reaction (PCR) for clonality analysis in lymphoid malignancies, but can produce false negatives due to the presence of IgH VH SHMs. To overcome this problem, three primer sets were designed for the three framework regions (FR1, FR2, and FR3). We evaluated the predictive value of this PCR pattern in patients with DLBCL. To evaluate the prognostic impact of complete detection of the clonal amplifications (VHFR1–JH, VHFR2–JH, and VHFR3–JH) in the BIOMED‐2 protocol, we retrospectively analyzed 301 DLBCL patients who were initially treated with anthracycline‐based immunochemotherapy. Complete detection of the FR1 to FR3 primer‐based IgH VH PCR patterns in the BIOMED‐2 protocol was associated with low frequency of VH SHMs (p |
