Patients who have recovered from malignant lymphoma are at an increased risk of secondary acute leukemia (AL), and overt AL is frequently preceded by a myelodysplastic syndrome. Although the statistical risk is significant, only a minority of the patients will be so affected. We have reviewed peripheral blood counts of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) treated in the Departments of Hematology at the Edith Wolfson and Chaim Sheba Medical Centers, Israel. Included were only those who went into a complete remission and remained lymphoma free for extended periods. There were 85 patients with HD and 36 with NHL. In both groups peripheral blood counts at diagnosis were within the normal range. A prolonged follow-up (> 4 y), during which no further treatment was given, revealed a sustained increment over time of MCV (delta MCV) both in HD and NHL. A persistent monocytosis in HD patients was also evident. delta MCV was larger in HD. The difference at the end of the follow-up period was as follows: 10.1 fl + 11.8 in HD vs 5.0 fl + 6.2 in NHL, (P < 0.001). In addition, a significant loss of the normal correlation between the MCV and levels of hemoglobin was seen at the last follow-up. The change in MCV was present in all treatment groups, its magnitude increasing from radiotherapy to chemotherapy to combined radio chemotherapy. This trend is in analogy to the risk of secondary AL which is lower in NHL vs HD. Furthermore, it is lowest post radiotherapy and highest when both treatment modalities are used.(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted a multi-institutional (33 institutes), late phase II study with a 21-consecutive-day oral administration of etoposide for malignant lymphoma. Patient entry criteria were either those refractory to standard therapies or those for whom no appropriate therapy was available. A once-daily dose of 50 mg/body was administered for 21 consecutive days. Of the evaluable 83 among 88 entry patients, the overall response rate was 53.0% (44/83), including 10 CR; 52.5% (42/80, 9 CR) with non-Hodgkin's lymphoma and 100% (2/2, 1 CR) with Hodgkin's disease. Regarding abnormal laboratory findings, myelosuppression was observed; the incidence rates of leukopenia (23.3% with Grade 3), neutropenia (32.6%), hemoglobin decrease (17.4%) and thrombocytopenia (4.7%) were 70.9%, 65.1%, 54.7% and 19.8%, respectively. Major adverse reactions and their incidence were: anorexia 43.0%, alopecia 37.2%, nausea/vomiting 32.6%, fatigue 18.6%, stomatitis 15.1%, fever 7.0% and diarrhea 5.8%. Therefore, a 21-consecutive-day oral administration of 50 mg/body/day or 75 mg/body/day appears to be effective for the treatment of malignant lymphoma.

A multicenter study of CA549, a marker for breast cancer, was conducted using sera from 1721 patients with benign and malignant conditions by an immunoradiometric assay, BRESMARQ. Acceptable assay performance was demonstrated by studies of intra-assay (2.2% to 12% coefficient of variation [CV]), interassay (4.1% to 11.8% CV), and interlaboratory (4.8% to 8.7% CV) precision; sensitivity (.3 kU/L); linearity; recovery; high-dose hook effect (up to 10,000 kU/L); and interferences (human antimouse antibodies; protein, bilirubin, hemoglobin levels; lipid and cancer therapeutic agents). A reference interval of 0-12.5 kU/L (women) and 0-11.9 kU/L (men) was established from 746 healthy persons. The distribution of values exceeding the reference range for benign conditions was as follows: pregnant and lactating women (2%); benign breast disease (5%); and seven other benign diseases, including liver (24%), lung (19%), prostate (14%), colon, endometrial, gastric, and ovarian (< 10%). For nonbreast cancers, the distribution was Hodgkin's (7%), colon (10%), endometrial (15%), gastric (15%), lymphoma (15%), prostate (20%), ovarian (39%), and liver (45%). For breast cancer, the distribution was stage I (5%), stage II (14%), stage III (32%), and stage IV (74%). The receiver-operating characteristic analysis demonstrated the usefulness of CA549 as a marker in stage IV breast cancer.

Acquired pure red cell aplasia (PRCA) has been associated with various lymphoproliferative conditions but its occurrence with Hodgkin's disease is rare. We report a case of PRCA occurring immediately following the completion of induction chemotherapy in a patient with Stage IIIB nodular sclerosing Hodgkin's disease. In vitro erythroid colony studies documented evidence for T cell mediated suppression of erythropoiesis and lack of a serum inhibitor. Addition of cyclosporin to the in vitro cultures stimulated erythroid colony growth. Following in vivo treatment with cyclosporin peripheral blood CD4/CD8 ratios returned to normal. However, serum erythropoietin levels were inappropriately low. Subsequent treatment with erythropoietin induced a reticulocytosis and transfusion independence. Since discontinuing the erythropoietin, the patient has been able to maintain a hemoglobin of 100 g/L. This case illustrates that red cell aplasia occurring in the setting of Hodgkin's disease may be due to T cell mediated suppression of erythropoiesis. A response to cyclosporin may be masked by inappropriately low erythropoietin levels.

The outcomes were analyzed retrospectively of 59 cases of non-Hodgkin lymphoma (NHL) that included prominent splenic involvement (LPS). Forty-three patients had low-grade NHL, and 16 had intermediate or high-grade NHL. Forty of the 59 patients underwent splenectomy. Four patients died postoperatively before any treatment, and 10 others received no chemotherapy or radiation therapy. Twenty-nine splenectomized and 16 patients whose spleens were not removed received chemotherapy or radiation therapy. One or more cytopenias were present in 45 patients (77%). Five (18%) of the 28 patients who initially were cytopenic underwent splenectomies that did not correct their blood disorders. The median actuarial survival was 108 months in splenectomized patients and 24 months in those not treated surgically (P = 0.0001). For the 40 splenectomized patients, a normal postoperative platelet count, an initial hemoglobin level of 110 g/l or more, and a postoperative hemoglobin level 110 g/l or more were associated with prolonged survival. These results suggest that cytopenias are frequent in LPS and that their reversal is observed after early splenectomy in 82% of cases. The absence of cytopenia after early splenectomy is associated with prolonged survival.

The ready access to blood (plasma and formed cellular elements) makes it unusually susceptible to the deleterious effects of pollutants whose origins may be in the air. The red blood cells' hemoglobin may be rendered useless for oxygen transport by combination with carbon monoxide or conversion to methemoglobin or sulfhemoglobin. Lead and arsine can damage the erythrocytes' membranes, resulting in anemia. Metabolites of benzene and other volatile polycyclic hydrocarbons are implicated in the causation of leukemias. The extensive use of pesticides and herbicides may be associated with the development of Hodgkin's disease, non-Hodgkin's lymphoma, and aplastic anemia. The carcinogenic risks from ionizing radiation, especially for leukemia, are well known. More information is needed concerning the epidemiology of environmental factors responsible for damage to blood. Enhanced knowledge about the molecular biology of toxins' effects on the hematopoietic system and improved detection and prevention technologies are needed to answer environmentally related health questions.

The erythrocyte lysate samples obtained from 10 healthy donors (aged of 23 +/- 12 years) and 16 patients with Hodgkin's disease (aged of 39 +/- 25 years) with the following histological types: 12 mixed cellularity and 4 nodular sclerosis, were studied. Patients with Hodgkin's disease (HD) were randomly selected before, during or after the completion of combined chemotherapy. A comparative analysis of peptide components of erythrocyte lysate samples of HD patients and healthy donors was carried out. The amino acid sequences of 4 peptides, corresponding to fragments 1-33, 1-32, 1-31 and 1-30 of human hemoglobin (Hb) alpha-chain were determined. Increase of the content of two fragments corresponding to 1-31 and 1-32 amino acid residues of alpha-globin were detected for HD patients. The link between the normal process of proteolytic degradation and those occurring during HD is proposed. The possibility of using the identified alterations recorded during HD diagnosis is discussed.

In a group of 73 patients with low-grade non-Hodgkin's lymphomas (LG NHL) a multivariate analysis of the following variables was performed: pathological types following the International Working Formulation, clinical stage, B-symptoms, erythrocyte sedimentation rate, hemoglobin level, white blood cell and lymphocyte count, serum gamma globulin level, serum total lactic dehydrogenase (LDH) level, mitotic and complete remission. The patients with lymphocytic lymphoma manifested the best survival in this group. Low-proliferative lymphomas showed better survival than high-proliferative lymphomas at 3 and 10 years. B-symptoms, serum total LDH level and complete remission were significant independent prognostic factors.

In 93 newly diagnosed lymphoma patients, tumor necrosis factor alpha (TNF alpha) and its p55 soluble receptor (p55-sR), were prospectively determined in plasma by IRMA and ELISA methods respectively. These 93 patients included 31 patients with low grade lymphoma, 55 with intermediate or high grade lymphoma and 7 with Hodgkin's disease. Median TNF alpha plasma values were 20 pg/mL (range 5-380 pg/mL) in patients versus 7 pg/mL (range 4-9 pg/mL) in healthy control subjects. Presence of TNF alpha level equal or greater than 20 pg/mL was significantly associated with elevated LDH level, serum beta 2-microglobulin level > or = 3 mg/L, hemoglobin < or = 12 g/dL, Ann Arbor stage III or IV disease, and with bulky tumor. High level of TNF alpha was also associated, although less strongly, with B symptoms, poor performance status, and serum albumin < or = 35 g/L, yet it was not associated with change in acute phase protein levels. Levels of p55-sR were also markedly elevated in these lymphoma patients (median of 3.5 ng/mL, range 0.8-18.8 ng/mL) versus 1.45 ng/mL in control subjects (range 1.1-2.3 ng/mL). Level of p55-sR equal or greater than 3.5 ng/mL was significantly associated with poor performance status, B symptoms, beta 2-microglobulin levels > or = 3 mg/L, serum albumin < or = 35 g/L, C-reactive protein > 6 mg/L, hemoglobin < or = 12 g/dL, and bulky tumor. In the whole group of 93 patients, both high TNF alpha and p55-sR levels strongly predicted short freedom from progression and overall survival. This study suggests that elevated TNF alpha and p55-sR plasma levels have a high correlation with other adverse prognostic factors in lymphoma patients and predict their poor outcome.

Antibodies against CD15, -30, and -20 are often used to support morphological diagnosis of Hodgkin's Disease (HD). The classical HD, i.e., the non-lymphocyte-predominance types, are CD15+, CD30+, and CD20- in general. However, the results for CD15 are less clear-cut in many studies, showing up to 40% of classical HD that lack positivity for this maker. Little is currently known about the relevance of antigen expression in relation to clinical outcome in HD. Therefore, the three markers were analyzed in 1751 cases from the German Hodgkin Study Group, using micro-wave epitope retrieval to optimize staining sensitivity. Eighty-three percent of the cases showed a classical immunophenotype (CD15+, CD30+, CD20-), twelve percent lacked CD15 positivity (CD15-, CD30+, CD20-), and five percent showed other combinations. For 1286 cases, clinical follow-up was available, which revealed significant differences for freedom from treatment failure (P = 0.0022) and overall survival (P = 0.0001) between cases with classical immunophenotype and CD15 negativity (CD30+, CD20-). Multivariate Cox regression using the three markers, age, sex, histology, stage, B-symptoms (fever, sweats, weight loss > 10% of body weight), hemoglobin, and erythrocyte sedimentation rate as factors showed that lack of CD15 expression in classical HD is an independent negative prognostic factor for relapses (P = 0.022) and survival (P = 0.0035). In conclusion, immunohistochemistry is able to identify classical HD cases with unfavorable clinical outcome.
