Intravascular large B-cell lymphoma (IVL) is a rare type of lymphoma characterized by tumor growth selectively within the vessels. The 5 th edition of the World Health Organization classification defines IVL as a large B-cell lymphoma, the same as diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Since the clinical manifestations of IVL are nonspecific, the diagnosis is time-consuming, and the course is often fatal. Serum soluble interleukin-2 receptor (sIL-2R) and serum lactate dehydrogenase (LDH) levels are known to be elevated in a variety of lymphomas. However, the mechanism of sIL-2R elevation in B-cell lymphomas is not fully understood. In this study, we analyzed the serum level of laboratory findings, including sIL-2R and LDH, as well as the presence of B symptoms in 39 patients with IVL, and compared them with 56 patients with stage IV DLBCL. Both sIL-2R and LDH levels were significantly higher in IVL than in DLBCL (p = 0.035 and p = 0.002, respectively). In IVL, there were no significant differences in both sIL-2R and LDH levels between patients with and without B symptoms (p = 0.206 and p = 0.441, respectively). However, in DLBCL, both sIL-2R and LDH levels were significantly higher in the presence of B symptoms (p = 0.001 and p < 0.001, respectively). The high sIL-2R and LDH levels in IVL may be related to the peripheral blood microenvironment, but further studies are needed to verify this.
