Slightly increased urinary albumin excretion rates (UAE) have been reported in patients with various types of human cancer. We measured UAE in 24 h urine samples from 48 untreated patients with non-Hodgkin's lymphoma at diagnosis. In patients with a pretreatment UAE >/=20 microgram/min, post-treatment value of UAE was determined following completion of the last treatment. The median UAE was 15.0 microgram/min and the prevalence of microalbuminuria (UAE >/=20 microgram/min) was 39.6%. Increased UAE was significantly associated with Ann Arbor stage, performance status, serum lactate dehydrogenase (LDH) level, and the International Prognostic Index (IPI). The median posttreatment value of UAE was significantly lower than the pretreatment value (P < 0.0001). Our data suggest a clinical and prognostic significance of UAE in patients with non-Hodgkin's lymphoma.

Ann Arbor staging classification (with Cotswolds modifications) is widely used to evaluate the cases of non-Hodgkin's lymphoma(NHL). Contrary to Hodgkin's disease, most patients with NHL have advanced and extranodal disease, and therefore Ann Arbor staging system is not satisfactory in all the cases of NHL. However, Ann Arbor clinical stage is a powerful prognostic factor when it is used with other prognostic factors, such as serum lactate dehydrogenase and performance status(International Prognostic Index). Clinical features of NHL are closely related to histologic subtypes, so newer staging system will be based on pathological diagnosis and clinical parameters.

The enzyme lactate dehydrogenase (LDH) activity of peripheral blood mononuclear cells (PBMC), LDH isotype H and M pattern and PBMC spontaneous LDH release activity were examined in 55 non-Hodgkin's lymphoma (NHL) patients, 46 Hodgkin's disease (HD) patients and 47 controls. The intracellular LDH and M isotype activity of PBMC, their spontaneous LDH release activity significantly increase (p < 0.01) in NHL with progressing histological grade of malignancy. Contrary to this, all classical HD patients have a significant elevation (p < 0.05) of each of these parameters. Furthermore, unlike HD, in NHL clinical stage is associated with significant (p < 0.05) increase in the level of spontaneous LDH release activity in each histological form. It is also shown that spontaneous LDH release activity of PBMC for HD and NHL patients demonstrates significant positive correlation (p < 0.005) with serum LDH level, although elevation of spontaneous LDH release precedes serum LDH increase in both diseases. The results obtained regarding alterations in intracellular, isotype and spontaneously released LDH activity of circulating PBMC show that these parameters are dependent, in NHL patients, on the grade of malignancy and tumor burden, while they are persistently present in HD patients.

From July 1990 to March 1996, 112 children with stage III or IV B-cell non-Hodgkin's lymphoma (B-NHL) with up to 70% FAB L3-type blasts (n = 42) in the bone marrow without central nervous system (CNS) disease were treated on the United Kingdom Children Cancer Study Group (UKCCSG) 9002 protocol (identical to the French LMB 84). The median age was 8.3 years. There were 81 boys and 31 girls. According to the extent of the primary disease, patients were sub-staged into three groups: IIIA with unresectable abdominal tumour (n = 39); IIIB with abdominal multiorgan involvement (n = 57) and IIIX with extra-abdominal primary lymphoma often presenting as pleural effusion (n = 16). Univariate and multivariate analyses were carried out to evaluate the prognostic significance of lactate dehydrogenase (LDH) level at diagnosis, the sub-stage and the time to achieve complete remission (CR). With a median follow up of 48 months (range 12-92), the overall and event free survival (EFS) is 87% (95% confidence interval (CI) 79.2-92.1 %) and 83.7% (95% CI 76.3-89.2%) respectively. Six patients (5.4%) never achieved CR, of whom one is alive following high-dose therapy. Eight patients (7.1%) relapsed after achieving CR, three are alive after second-line therapy. There were three early toxic deaths (2.7%), mainly from infection, and one late death from a second cancer. There was no significant difference in EFS according to LDH level at diagnosis, the sub-stage or the time to CR. This study confirms the overall good prognosis and low rate of toxic deaths in patients with advanced B-NHL treated with this intensive regimen. No significant difference in EFS according to the sub-stage, the time to achieve CR or LDH level at diagnosis making it difficult to identify a group that should not receive intensive therapy.

Soluble Fas (sFas) blocks apoptosis induced by Fas ligand in vitro. The serum concentration of sFas is elevated in lympho-proliferative diseases. We hypothesized that higher levels of sFas worsen the clinical symptoms and outcome of patients with aggressive non-Hodgkin's lymphoma (NHL). We prospectively measured the serum concentrations of sFas in 67 consecutive patients with aggressive NHL (59 with diffuse large cell lymphoma and 8 with diffuse small cleaved cell lymphoma). sFas was significantly elevated in patients with aggressive NHL compared to healthy controls (N = 36, P< 0.005), while sFas in patients with B symptoms (4.20 +/- 2.12 microg/l) was significantly higher than in those without B symptoms (2.66 +/- 1.08 microg/l, P < 0.005). No significant difference was observed between B-cell lymphoma and T-cell lymphoma or between patients with clinical stage I or II and those with clinical stage III or IV. Significant correlations were found between sFas concentration and both soluble interleukin-2 receptor (R = 0.400, P < 0.001) and C-reactive protein (R = 0.340, P < 0.01) levels in patients with aggressive NHL. No correlation was observed between sFas and either white blood cell count or lactate dehydrogenase. Generalized Wilcoxon analysis revealed that NHL patients with sFas less than 4 microg/l had better overall survival than those with sFas above 4 microg/l (P < 0.001). The serum concentration of sFas might be associated with clinical symptoms and the prognosis of patients with aggressive NHL.

Bone marrow necrosis is a rare finding in adult patients diagnosed with acute leukemia or non-Hodgkin's lymphoma. Previous reports have suggested that it is associated with a poor prognosis. It remains unclear however, whether improvements in patient care during the last decade have altered patient outcome. In a retrospective review of 581 bone marrow biopsies performed ante mortum on adult patients with acute leukemia or non-Hodgkin's lymphoma, we identified 10 cases of bone marrow necrosis (5 acute myeloid leukemia, 5 non-Hodgkin's lymphoma). Severe bone pain, elevated serum lactate dehydrogenase levels and leukoerythroblastic peripheral blood smears were common presenting features. Despite treating 8 of the 10 patients with curative intent, only 2 patients remain alive and disease-free. This study confirms that bone marrow necrosis in adults with acute leukemia and non-Hodgkin's lymphoma is a rare ante mortum finding and confers a poor prognosis. Whether these patients would benefit from more intensive therapy such as hematopoietic stem cell transplantation remains to be clarified.

Using DNA extracted from plasma samples of B-cell non-Hodgkin's lymphoma (B-NHL) patients, we attempted to detect the monoclonal rearrangement of immunoglobulin heavy chain gene by amplifying complementarity-determining region 3 (CDR3) by semi-nested polymerase chain reaction (PCR) method (plasma PCR). In 19 of 37 (51%) cases, clonal DNA was detected. With the same PCR method using DNA extracted from peripheral blood mononuclear cells, clonal DNA was detected in 8 of the 37 cases (22%). These 8 were in advanced stages with bone marrow (BM) invasion mostly. On the other hand, the 19 positive cases by plasma PCR included those in early stages without BM invasion or with normal soluble interleukin-2 receptor (sIL-2R) and lactate dehydrogenase (LDH) values. In 15 healthy volunteers, plasma PCR showed no clonal DNA. In cases in which tumor biopsy was difficult to perform, plasma PCR was helpful for determining whether or not the tumor was B-NHL. Plasma PCR is simple and has high specificity, although its sensitivity is insufficient.

A variant form of CD44 that has additional amino acids in the common protein backbone (CD44-v6) seems to play a role in the metastasis of malignancies. We measured soluble CD44-v6 (sCD44-v6) by ELISA in 201 patients with malignant lymphoma. The sCD44-v6 level was significantly elevated in patients with non-Hodgkin's lymphoma (NHL) (n = 184). The sCD44-v6 level was correlated significantly with the standard sCD44 and soluble interleukin-2 receptor levels, but only weakly with serum lactate dehydrogenase (LDH). In 149 patients with aggressive NHL, the sCD44-v6 level was elevated in the subgroups with a high LDH level, stage III/IV disease, T-cell lymphoma, and high-intermediate or high risk group as identified by the International Prognostic Index (IPI). When the sCD44-v6 level was > or = 800 ng/ml the overall survival rate was significantly decreased (p = 0.0001). In the low + low-intermediate risk group (IPI) both overall survival rates (log-rank p = 0.0005, Wilcoxon p =0.002) were significantly decreased when the sCD44-v6 level was > or = 800 ng/ml. In multivariate analysis, sCD44-v6 was shown to be independent of the five prognostic factors in the IPI (age, performance status, number of extranodal sites, Ann Arbor stage and LDH level), so it may be useful for predicting the outcome of aggressive NHL.

Acute renal failure due to diffuse renal infiltration is rarely the presenting manifestation of non-Hodgkin's lymphoma. We report a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a Burkitt's lymphoma. The presence of bilateral renal enlargement, an elevated serum lactate dehydrogenase (LDH), and lymphopenia should suggest the diagnosis, which can be confirmed by renal biopsy.

A case of angiotropic B-cell lymphoma associated with hemophagocytic syndrome (HPS) has been reported. In addition to fever, pancytopenia, hepatosplenomegaly, and lack of lymphadenopathy, unique clinical features, such as syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and pulmonary infarction, were manifested. Both soluble interleukin-2 receptor (sIL-2R) and IL-6 were elevated in the patient's sera in addition to an increase of serum lactate dehydrogenase and ferritin. In contrast, tumor necrosis factor-alpha and interferon-gamma were within normal ranges. Serum antibodies against Epstein-Barr virus and cytomegalovirus showed a past infection pattern. An autopsy examination revealed systemic intravascular proliferation of lymphoma cells with a B-cell phenotype, confirming the diagnosis of angiotropic B-cell lymphoma. Moreover, SIADH was suggested to result from the infiltration of tumor cells into the pituitary gland. Triple association of angiotropic B-cell lymphoma, HPS and SIADH is quite rare. Therefore, the present case seems to be helpful for clarifying the mechanism for HPS of non-Hodgkin's lymphoma with B-cell origin.
