The serum levels of soluble intercellular adhesion molecule 1 (ICAM-1) were significantly elevated (P < .001) in patients with chronic B-lymphocytic leukemia (B-CLL, n = 113) compared with healthy controls (n = 31). sICAM-1 levels in B-CLL were positively correlated to the tumor mass as reflected by the modified Rai and the Binet staging systems, lymphocyte counts, and isolated spleno/hepatomegaly. During disease progression or regression on cytoreductive therapy, the circulating sICAM-1 levels changed accordingly. sICAM-1 was also correlated to a kinetic parameter such as the lymphocyte doubling time. Furthermore, the serum sICAM-1 levels were inversely correlated to hemoglobin levels in patients with early clinical stage, and this may turn out to be of prognostic value. sICAM-1 was compared with other serum markers said to reflect disease activity in B-CLL, ie, soluble CD23, thymidine kinase, lactate dehydrogenase (LDH), and beta 2-microglobulin. sICAM-1 was equally well or better correlated to clinical stage and lymphocyte doubling time. In univariate regression analysis, all serum markers but LDH correlated with survival, and in multivariate analysis, sICAM-1 was the only marker approaching significance for additional prognostic information when included after clinical stage and lymphocyte doubling time. Based on the present observations, it appears that prospective studies repeatedly monitoring serum sICAM-1 in B-CLL are justified.

We present the clinical and immunological features of a rare case of chronic lymphoid leukaemia with lymphoplasmacytoid morphology. The patient was first admitted suffering from weakness, pallor, dyspnoea, marked splenomegaly, hepatomegaly and systemic lymphadenopathy and panhypogammaglobulinaemia. White blood cell count revealed important leukocytosis (220 x 10(9) WBC/l) with 2% neutrophils and 98% lymphoid cells showing lymphoplasmacytoid features, while lymphoid cells of identical morphology severely infiltrated the bone marrow and lymph nodes. The disease, initially controlled by non aggressive chemotherapy over a period of 30 months, later evolved to a clinical and haematological picture suggestive of Richter's syndrome. Immunophenotyping of the leukaemic cells demonstrated a monoclonal expansion of B-cells bearing surface markers of typical CLL (CD5, CD19, CD20, CD21, CD22, CD23, CD24, CD40 and low density IgM+IgD/kappa) and also the CD11c and CD38 antigens. A proportion of these cells expressed activation markers (CD25, CD69 and CD71). Following in vitro activation with TPA or PWM, the cells responded by weak incorporation of 3H-TdR but failed to secrete immunoglobulins. These findings confirm the broad morphological, phenotypical and clinical spectrum of chronic lymphoid leukaemias.

Fifty four cases of CLLB were studied from 1st of April. 1990 to October 30, 1993; 35 male and 19 female (M:F = 1.8:1) in age 39-76 years (median age = 62 years). 81% patients had lymphadenopathy, 30%--hepatomegaly, 31% splenomegaly, 24% had allergic symptoms, 24% had anaemia (7% AINH). 13% thrombopoenia (2% autoimmunologic thrombopoenia). In all cases immunological phenotype of peripheral blood lymphocytes was determined, 100% patients had B cells CD5+, 70% lymphocytes sIg+, 97%-CD19+, 73%-CD23+, 67%-CD22+, 82%-HLADr, 10%-71(TR90), CD10 was negative. There was negative correlation between B CD5+ cells and life span (p < 0.03). There was positive correlation, between CD23 and bulky diseases (p < 0.01). Percentage of T cells with CD2+, CD3+, CD4+, CD8+ and CD4:CD8 was diminished. Lymphocytosis T with antigens CD2+, CD3+, CD4+, CD8+ was enhanced. There was found a positive correlation between lymphocytosis CD2+ (p < 0.00009), CD4+ (p < 0.008), CD8+ (p < 0.0008) and blood lymphocytosis and positive correlation between T lymphocytosis CD2+ (p < 0.02), CD4+ (p < 0.002) and lymphocytosis bone marrow.

Mantle-cell lymphoma (MCL) is a B-cell malignancy with distinct molecular genetics and pathological features. Peripheral blood involvement has been reported with variable frequency, but information on the natural history of cases presenting with leukemia is lacking. This study aimed to determine the clinical and prognostic features of such cases. We studied clinical features, tumor characteristics, prognostic factors and outcome in 58 patients with leukemic presentation of MCL. Diagnosis was based on morphology, immunophenotype, presence of t(11;14), histology and cyclin D1 expression. The median age was 62 years and male:female 2.4:1. Presenting features included splenomegaly (74%), lymphadenopathy (45%), hepatomegaly (17%) and, in a minority, gastro-intestinal involvement or involvement of Waldeyer's ring; 10% had lymphocytosis alone. Six patients developed central nervous system disease. Median lymphocyte count was 58 x 10(9)/l, 55% had anemia and 17% had thrombocytopenia. Morphology of peripheral blood showed small-cell MCL in 15% of cases, typical MCL in 46% and blastoid MCL in 39%. Immunological markers showed a typical phenotype (CD5+ CD23 -) in 68%, and atypical phenotypes, CD5- CD23- in 17% or CD5+ CD23+ in 15%. CLL scores were 0, 1 or 2 in 96%. Median overall survival was 36 months. Good response to first-line treatment (P = 0.0008) and splenomegaly (P = 0.03) were favorable prognostic factors, while other features including morphology and CD38 expression had no impact on survival or treatment response. This analysis demonstrates that except for splenomegaly, survival of MCL patients presenting with leukemia is not significantly influenced by clinical or tumor characteristics. Splenectomy is a useful treatment option in this group of patients.

Hairy cell leukemia (HCL) has been mainly reported from the Western countries. Herein we describe a case of HCL diagnosed in a Thai patient. A 36-year-old man presented with abdominal discomfort, frequent gum bleeding and significant weight loss for 2 months. Physical examination revealed moderate anemia, petechial hemorrhage on the extremities and an enlarged spleen down to the umbilicus. No hepatomegaly or lymphadenopathy was detected. Complete blood counts revealed a hemoglobin (Hb) of 6.6 g/dL, a white blood cell (WBC) count of 1.6 x 10(9)/L (neutrophil 16%, lymphocyte 71%, monocyte 11%, atypical lymphocyte 1%), and a platelet (PLT) count of 17 x 10(9)/L. Abnormal large mononuclear cells with villous projections were seen in the blood smear. Although bone marrow (BM) aspiration resulted in a dry tap, abnormal lymphocytes with villous projections could again be identified in the touch preparation. Flow cytometric analysis showed a distinct population above the normal lymphocyte region on CD45/SSC gates with a strong expression of CD19, CD20, CD22, CD25, CD11c, and kappa. CD5, CD23, CD10, CD4, and CD8 were all negative. BM biopsy was consistent with HCL. The patient was treated with splenectomy followed by 8 cycles of fludarabine and cyclophosphamide chemotherapy. At 21 months after diagnosis, the patient was doing well with a Hb of 16.9 g/dl, a WBC count of 6.8 x 10(9)/L, neutrophil 49.9%, lymphocyte 39.6%, monocyte 8.6%, and a PLT count of 329 x 10(9)/L). No abnormal lymphoid cells were detected in the blood smear. This present report represents the first Thai HCL case that was immunophenotypically confirmed by flow cytometry and successfully treated at Siriraj Hospital.
