Serum beta-2-microglobulin (S-beta 2M) was measured at diagnosis in 44 patients with lymphocytic leukemias and 47 with malignant lymphomas. Among patients with chronic lymphocytic leukemia (CLL) S-beta 2M was raised (greater than 3 mg/l) in 74% and in 23.5% of those with acute lymphoblastic leukemia (ALL). The frequencies for non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) were 59.2% and 40%, respectively. In CLL patients high serum values correlated with large tumor mass, as estimated by Rai's clinical criteria (P less than 0.001), by total peripheral lymphocytes (r = 0.41, P less than 0.05) and by the percentage of bone marrow infiltration of the lymphocytes (P less than 0.01). A significant relation was also found in CLL patients between S-beta 2M level and survival (P less than 0.05). In ALL no association was found between S-beta 2M level with peripheral lymphoblast concentration, French-American-British (FAB) subclassification, splenomegaly, and survival. In NHL patients a significant association was found between S-beta 2M levels and stage of disease (P less than 0.01) and an obscure relation (P less than 0.1) with the presence of lymph nodes greater than 3 cm in diameter, splenomegaly, and hepatomegaly. No significant association was found between S-beta 2M level and histologic subtypes, presence of B symptoms, bone marrow involvement, and survival. In HD patients a significant association was found between the level of S-beta 2M and stage of disease (P less than 0.05) and presence of splenomegaly (P less than 0.05). No association was found between S-beta 2M level and histologic subtypes, lymph nodes greater than 3 cm in diameter, bone marrow involvement, and B symptoms. A significant relation was found between S-beta 2M level and survival in HD patients with widespread disease (P less than .025).

Prognostic factors in a group of 90 patients with chronic lymphocytic leukemia were studied by methods of survival analysis. The relationship between survival and a set of demographic, clinical and laboratory variables, and identification of subsets of variables that are associated with survival, was tested by multivariate analysis, which is based upon Cox proportional hazards regression models in a stepwise procedure. Six variables showed significant correlation with survival: lymph node enlargement, splenomegaly, hepatomegaly, increased percentage (greater than 80%) of lymphocytes, hyperuricemia, and anemia. Stepwise analysis showed that the number of coexistent risk factors was a better predictor of survival than any single risk marker (P less than 0.001). Median survival of patients with 0 or 1 risk marker was 120 months; with 2 or 3, 96 months; with 4, 36 months; and with 5 or 6, only 24 months. Comparison of staging by number of risk markers with staging of the same patients by the Rai system showed a significant trend of decreasing survival with increasing number of risk markers within the same Rai stage. Staging by the number of coexistent risk markers is a simple and readily available method, which may complement existing methods to provide a more accurate assessment of prognosis in patients with chronic lymphocytic leukemia.

In previous studies, the prognostic value of bone marrow (BM) histologic patterns in chronic lymphocytic leukemia (CLL) has been demonstrated. In order to investigate whether such a value is independent of other prognostic parameters, a multivariate survival analysis (Cox's regression model) was undertaken in a series of 329 CLL patients in whom a BM had been performed. The following binary variables were included in the analysis: age (more than 60 years), lymphadenopathy (more than two areas involved), splenomegaly, hepatomegaly, absolute lymphocyte count (more than 30,000 microL), anemia (hemoglobin less than 10 g/dL), thrombocytopenia (less than 100,000 microL), and BM pattern (diffuse v nondiffuse). Three variables entered the regression at significant level: BM pattern (P less than .001), anemia (P less than .001), and hepatomegaly (P = .03). The model was also tested by expressing the variables in a continuous way when possible. Again, BM pattern entered first in the regression (P less than .001), followed by the hepatomegaly (P = .002), hemoglobin level (P = .02), and lymphadenopathy (P = .04). When both the binary and the continuous models were tested separately in 227 patients with BM as initial staging procedure and in 102 patients in whom this was performed later during the course of the disease, in all instances, BM pattern entered first in the regression at a highly significant level. BM histologic pattern appears to be a better single prognostic parameter than any one of the variables employed in current clinical staging systems. A combined clinicopathologic system incorporating the BM pattern, together with the usual clinical variables, is presented.

Fifty-two patients with different types of leukemia [27 chronic lymphocytic leukemia (CLL), 10 acute myeloblastic leukemia (AML), eight acute lymphoblastic leukemia (ALL), four chronic myelogenous leukemia (CML), and three hairy cell leukemia (HCL)] had abdominal and pelvic CT. The radiographic features are reviewed to evaluate the role of CT in diagnosis and management of these patients. The highest incidence of lymphadenopathy was observed in CLL followed by HCL and ALL. Other findings included splenomegaly, hepatomegaly, ascites, pleural effusion, microabscesses in liver and kidney, and visceral involvement, i.e. intestine, bladder, and bone.

This is a case report of a patient with invasive thymoma. Subsequently to radiotherapy and steroids, a combination chemotherapy of cis-platinum (CDDP) and doxorubicin was tested with good results. The patient later developed a chronic lymphocytic leukemia (CLL); morphologically and cytochemically a T-CLL with skin localizations, hepatomegaly, and a high leukocyte count.

Using affinity-purified 125I-F(ab')2 anti-human C3, we have investigated the ability of various leukemic cells to activate complement. Lymphocytes from patients with chronic lymphocytic leukemia (CLL) activated the alternative pathway, but cells from patients with other forms of leukemia or normal lymphocytes did not do so. The amount of C3 deposited on the CLL cells was significantly higher in patients with organomegaly (i.e., splenomegaly and/or hepatomegaly). Activation of complement by CLL cells as assessed by C3 deposition on the membrane occurred both in vivo and in vitro and was not related to the N-acetylneuraminic acid content of the membrane.

Over an 18-year period a distinctive large cell lymphoreticular neoplasm (Richter's transformation) developed in 9 patients with chronic lymphocytic leukemia. Clinical findings at the onset of Richter's transformation were remarkably uniform and consisted of the abrupt onset of fever, marked asymmetric lymphadenopathy with the formation of masses, splenomegaly, and hepatomegaly. All patients underwent rapid clinical deterioration followed by death within six and a half months. Earliest infiltrates of large lymphoreticular cells were identified in the lymph nodes in 3 of 4 patients and the bone marrow in 3 of 9 patients, while no patient had peripheral blood involvement. Autopsy examinations revealed extensive infiltrates of large lymphoreticular cells, predominantly in bone marrow, lymph nodes, liver, spleen, but also in kidney, lung, and gastrointestinal tract. In each case, these large lymphoblast-like and pleomorphic lymphoreticular cells were admixed with mature-appearing lymphocytes and intermediate forms (prolymphocytes). Electron microscopic and immunoperoxidase studies provided additional evidence that this highly aggressive lymphoreticular neoplasm represents a transformation or dedifferentiation of chronic lymphocytic leukemia.

Forty-seven consecutive patients with chronic lymphocytic leukemia (CLL) followed in the Clinica Medica and the Sezione di Ematologia of Ferrara from January 1966 to June 1979 were classified according to the staging system of Rai and to age, sex and the occurrence of enlarged spleen or liver or both. Analysis of actuarial survival curves revealed the following: 1) the method of staging proposed by Rai was confirmed to be a reliable predictor for prognosis of CLL; 2( neither age nor sex do appear to be prognostic factor; 3) the enlarged liver did not appear to make worse the prognosis of CLL, probably by hepatomegalies due to other aetiologies. Furthermore the bound of peripheral lymphocytosis of 15,000/mm3, also according to other authors, seems to be too high: numerous cases of undoubted CLL with smaller lymphocytosis ae left out of this and other statistics published on CLL.

We report 26 elderly patients (median age 68.3 years) who met diagnostic criteria for B-cell chronic lymphocytic leukaemia (B-CLL) but whose lymphocytes lacked CD5 expression. Haematological and clinical features of this CD5- series were compared with those of 333 CD5+ B-CLL patients from the same institute. No significant differences were observed regarding peripheral blood (PB) and bone marrow (BM) lymphocytosis, Hb level, platelet count, incidence of adenomegaly, hepatomegaly or splenomegaly or diffuse BM pattern. Due to an absence of nodal enlargements or to general clinical condition, lymph node biopsy was performed in only three patients, while spleen histology was examined in two cases following splenectomy. All histological results confirmed the clinical diagnosis of CLL. The distribution of the CD5- subjects according to the different staging categories proposed by Rai, Binet and Mandelli was similar to that of CD5+ subjects. Ten patients received standard chemotherapy with Chlorambucil (CHL) and Prednisone (PDN). All achieved partial remission, although one of these patients later died of disease progression; 80 months after diagnosis. We conclude that rare cases of CD5- lymphocytosis fulfilling all criteria for B-CLL may occur. Haematological and clinical features at presentation and the response to conventional treatment with Chlorambucil support our hypothesis of considering this disease as a less frequent subgroup of B-CLL.

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.
