Stromal cells isolated from lymph nodes of adult T-cell leukemia/lymphoma (ATL) patients were cultured. Such lymph node stromal cells (LNSC) could be maintained for more than one year, whereas LNSC from other lymphoproliferative disorders ceased to proliferate within months. The rate of human T lymphotropic virus type I (HTLV-I) integration in these LNSC was examined by nested polymerase chain reaction (PCR) and estimated to be about 1 genome per 100 cells. These LNSC showed the same combination of cytokine production irrespective of the patient origin, granulocyte-macrophage (GM)-CSF, G-CSF, interleukin (IL)-1 beta, IL-6, interferon (IFN)-gamma and IL-8, being positive but not M-CSF, IL-1 alpha, IFN-alpha, tumor necrosis factor (TNF)-alpha, IL-2, LD78 and the IL-1 receptor antagonist (IL-1ra). The results show that LNSC from ATL patients have pronounced proliferation activity and constitutively secrete various cytokines. They therefore provide useful models for studying the microenvironment of lymph nodes in vitro, and especially the growth mechanism of ATL cells.

Interleukin-8 (LL-8) and granulocyte-macrophage colony-stimulating factor (GM-CSF) are cytokines/hematopoietic growth factor and are important mediators of inflammation and immune resoponse producing pathophysiological changes in human disease. Levels of IL-8 and GM-CSF in circulation of various hematologic diseases are unknown. To demonstrate their importance in lymphoproliferative disorders, we have measured the circulating levels of these two cytokines from patients with chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD). IL-8 and GM-CSF levels were determined by highly specific enzyme-linked immunosorbent assays. IL-8 levels were elevated in most patients with B-cell malignancies, B-cell CLL (B-CLL) and B-cell NHL (B-NHL) as well as in patients with HD. However, GM-CSF levels were higher in most patients with NHL (T-NHL and B-NHL) and HD. IL-8 was undetectable in T-cell malignancies (T-CLL and T-NHL), whereas GMCSF was undetectable from CLL (T-CLL and B-CLL). Of interest, IL-8 levels were correlated with white blood cell counts (WBC) in B-cell malignancies (B-CLL and B-NHL) but not in HD. These results suggest that both IL-8 and GMCSF may play an important role in pathophysiological changes in B-NHL and HD. IL-8 may be related with recruitment and activation of neutrophils, whereas, GM-CSF in proliferation and differentiation of hematopoietic progenitor cells and immune response in these malignancies. The clinical status of B-CLL patients in regards to WBC counts appeared to be associated with the serum levels of IL-8.

Histopathology alone cannot predict the outcome of patients with CD30+ primary cutaneous lymphoproliferative disorders (CD30CLPD) and early mycosis fungoides (MF). To test the hypothesis that serum cytokines/cytokine receptors provide prognostic information in these disorders, we measured soluble CD30 (sCD30), sCD25, and selected cytokines in cell cultures and sera of 116 patients with CD30CLPD and 96 patients with early MF followed up to 20 years. Significant positive correlation was found between sCD30 levels and sCD25, CD40L, IL-6, and IL-8, suggesting that CD30+ neoplastic cells secrete these cytokines, but not Th2 cytokines. In vitro studies confirmed that sCD30, sCD25, IL-6, and IL-8 are secreted by CD30CLPD-derived cell lines. CD30CLPD patients with above normal sCD30 and sCD25 levels had worse overall and disease-related survivals, but only sCD30 retained significance in Cox models that included advanced age. High sCD30 also identified patients with worse survival in early MF. Increased IL-6 and IL-8 levels correlated with poor disease-related survival in CD30CLPD patients. We conclude that (1) neoplastic cells of some CD30CLPD patients do not resemble Th2 cells, and that (2) high serum sCD30, sCD25, IL-6, and perhaps IL-8 levels may provide prognostic information useful for patient management.
