Abstract
AML-M0 is an infrequent form of acute myeloblastic leukemia characterized by negative reaction with myeloperoxidase (MPO), Sudan Black and lymphoid antigens and positivity for CD13 or CD33. In the present study we describe the immunophenotypical and ultrastructural characteristics of a group of AML-M0 in adult patients. Nine out 218 AML leukemias (4.1%) fulfilled the AML-M0 criteria. CD13 or CD33 were positive in eight out nine cases, with two or more positive myeloid antigens being present in 82% of the cases. Immunological MPO was positive in 57% of the cases and CD68 in 33%. In no case megakaryocytic and erythroid markers present. Four cases (44%) expressed CD7 and TdT but only two coexpressed both antigens. In none of the cases was CD3 or CD22 cytoplasmic expression found. Ultrastructurally, a low number of granules was seen in all cases whereas ferritin particles or rhopheocytosis were not observed. Ultrastructural MPO was positive in one out of five cases and platelet peroxidase (PPO) was negative in the four cases studied. Two out of six cases showed karyotypic abnormalities (hypotetraploidy and a complex karyotype, respectively). In two out three cases a rearranged pattern for JH gene was observed. TCR (Cbeta and Jgamma) rearrangements were not detected in any case. AML-M0 is an infrequent form of acute myeloblastic leukemia. A large panel of myeloid monoclonal antibodies (MoAb) and the study of the cytoplasmic expression of myeloid antigens is necessary to diagnose this form of leukemia. AML-M0 usually coexpress lymphoid markers. Ultrastructural studies may be of help to discard an immature erythroid proliferation.

Abstract
BACKGROUND AND OBJECTIVE The management of non-Hodgkin's lymphomas (NHL) in AIDS is difficult because of the poor bone marrow reserve and immunosuppression of these patients. Combination chemotherapy is the treatment of choice in the subset of patients with good performance status and mild immunosuppression. Several combination chemotherapy regimens have been used in these patients but the results have been poor. We have studied the clinical and biological features, response to treatment, outcome and prognostic factors of 46 patients with NHL and HIV infection, diagnosed in a single institution between January 1988 and June 1997. DESIGN AND METHODS Forty-six patients with NHL and HIV infection were treated with CHOP. Patients with previously treated systemic NHL, primary CNS NHL, performance status > 2 and active AIDS-defining opportunistic or neoplastic diseases were excluded. The parameters evaluated were: age, sex, risk activity, basic hematologic and biochemical parameters, CD4 lymphocyte count, B symptoms, stage (Ann Arbor), histologic subtype (REAL classification), International Prognostic Index (IPI), response to treatment, relative dose intensity (RDI), relapse free survival (RFS) and overall survival (OS). Uni- and multivariate analyses of prognostic factors were performed. RESULTS Median age was 35 years and 40 patients were male. CD4 lymphocyte count was lower than 0.1 x 10(9)/L in 18 out of 38 cases, hypoalbuminemia was registered in 24 (52%), serum LDH was higher than 400 U/L in 20 (43%) and beta 2-microglobulin was higher than the normal range in 9 out of 20 patients (45%). Complete response was achieved in 18 patients (40%). Twenty-six patients received G-CSF after chemotherapy. Grade 4 neutropenia and fever were significantly more frequent in patients who did not receive G-CSF. Serum LDH > 400 U/L and hypoalbuminemia were the only parameters associated with a lower probability to achieve complete response (p = 0.015 and p = 0.025, respectively). The median RFS was 26 (6-47) months and no variable was found to have statistically significant influence on it. The median OS was 9.2 (4.5-14) months, and IPI score 1 and ESR < 60 mm/h were the only parameters identified as good prognostic factors in the multivariate analysis (p = 0.03 and 0.049, respectively). INTERPRETATION AND CONCLUSIONS In spite of patient selection, the response to CHOP treatment in patients with NHL and HIV infection remains poor. Episodes of neutropenic fever are less frequent when G-CSF is administered after CHOP. The IPI score 1 is the most important favorable prognostic factor for survival.

Abstract
Phenotypic changes in neutrophil granulocytes (NG) after G-CSF have been scarcely studied. Using flow cytometry, we analyzed the changes of CD11b, CD14, CD33, CD71, HLA-DR, CD10, CD16 and CD15 on NG after G-CSF treatment in 6 patients with ALL receiving intensification chemotherapy and in 10 control subjects. After G-CSF we found: expression of HLA-DR, a higher expression of CD11b, CD71 and CD14, a decrease in CD10 positivity, and fluoresence Intesity in CD15 and CD16. After administration of G-CSF, the NG of patients with ALL express an immature phenotype as well as markers of proliferation.

Abstract
BACKGROUND AND OBJECTIVE Intensive induction and post-remission therapies have improved the prognosis in adult acute lymphoblastic leukemia (ALL). However, different from children, the impact of late intensification therapy in the overall results of treatment has not been consistently evaluated. The objective of this study was to analyze the results of a multicenter prospective protocol, PETHEMA ALL-89, in which, after intensive induction and consolidation therapy, randomization to receive delayed intensification treatment was performed. DESIGN AND METHODS One hundred and eight adults (age > or = 15 years) diagnosed with ALL (ALL L3 excluded) in 22 Spanish hospitals from 1989 to 1994 were treated with a five-drug induction therapy, followed by four cycles of early post-remission treatment during four months, and maintenance therapy for two years. Patients in remission at the end of the first year were randomized to receive one six-week cycle of late intensification therapy. Uni- and multivariate analyses of early response to treatment, complete remission (CR), leukemia-free survival (LFS) and overall survival (OS) were performed. RESULTS The median (range) age of the series was 28 (15-74) years and leukocyte count 26 x 10(9)/L (1-600). ALL L1/L2 was present in 38/70 patients, early pre-B in 13, common in 53, pre-B in 12 and T in 30 cases. The CR rate was 86%, and refractory disease 9%. Median LFS was 34 months, with a 5-yr probability of 41% (95% CI, 29-53), whereas median OS was 51 months and 5-year probability 47% (34-59%). There were no differences in either LFS and OS between patients who did or did not receive delayed intensification therapy. Prognostic factors for CR attainment were advanced age and slow response to therapy. These two features were, in addition to high leukocyte counts, the parameters with negative influence in both LFS and OS. INTERPRETATION AND CONCLUSIONS The results of PETHEMA ALL-89 are similar to those referred in other chemotherapy-based protocols in adult ALL. Delayed intensification has not improved the length of remission and survival. Efforts to improve the prognosis of adult ALL patients must be mainly focused in early intensification treatment.

Abstract
A patient with apparent anaemia and thrombocytopenia caused by a monoclonal paraprotein is described. The patient's serum contained a monoclonal IgM kappa, a cryoglobulin and a cold agglutinin. The cryoglobulin, similar to the serum paraprotein, was a monoclonal IgM kappa. Serum was studied to determine the relationship of the cryoglobulin with the cold agglutinin. The cryoglobulin and cold agglutinin were found to be the same paraprotein. Moreover, with absorption and elution techniques the reactivity of the autoantibody with both erythrocytes and platelets was demonstrated. Reports of cryoprecipitable cold agglutinins are rare and therefore this case is exceptional given that the IgM kappa paraprotein was found to be a cold agglutinin which was also reactive with platelets.

Abstract
BACKGROUND The goal of this study was to analyze the presenting features, natural history, and prognostic factors in 59 patients with well characterized mantle cell lymphoma (MCL). METHODS Cases were classified as nodular or diffuse and as typical or blastic variants. Age, performance status (PS), histologic variants, mitotic index (MI), hematologic parameters, tumor extension data, and International Prognostic Index (IPI) were recorded and evaluated for prognosis. RESULTS The median age of the patients was 63 years (range, 39-83 years), and the male to female ratio was 3:1. Fifty-three patients had typical histology (3 nodular and 50 diffuse), and 6 had the blastic variant. Approximately 95% of patients presented with advanced stage disease (Ann Arbor Stage III-IV). Leukemic expression was observed in 58%. Complete and partial response rates were 19% and 46%, respectively. Parameters associated with lower response rate were Stage IV, high/intermediate or high risk IPI, and increased lactate dehydrogenase (LDH) level. In the logistic regression analysis, high LDH level and Stage IV disease were associated independently with lower response rate. Median survival was 49 months. Parameters associated with a short survival were: poor PS, splenomegaly, B-symptoms, MI > 2.5, leukocyte count > 10 x 10(9)/L, high LDH level, blastic variant, and high/intermediate or high risk IPI. In the Cox proportional hazards regression model, only poor PS (relative risk [RR] = 3.3; P = 0.002), splenomegaly (RR = 2.8; P = 0.007), and MI > 2.5 (RR = 2.4; P = 0.012) were associated with short survival. CONCLUSIONS In this series, patients with MCL presented with advanced stage and extranodal involvement. Only a minority of patients achieved a complete response. The median survival was 4 years, with PS, splenomegaly, and MI being the most important factors predicting survival. These results show clearly that more effective therapies for MCL are needed.

Abstract
BACKGROUND To analyze the response to eradicative therapy and prognostic factors in 52 patients with primary gastrointestinal lymphoma (PGIL) diagnosed at a single institution in a 13 year period. PATIENTS AND METHODS The main clinical, biological and evolutive data were recorded. Pathologic diagnosis of PGIL was made according to the Working Formulation. Clinical stage was determined by the Ann Arbor system modified by Mushoff. The results of therapy as well as the influence of such characteristics on complete remission (CR), disease-free survival (DFS) and overall survival (OS) were studied. RESULTS Mean age of the series was 53 years (SD 15). Thirty patients were males. HIV infection preceded PGIL diagnosis in 10 cases. Seventeen had bad performance status (ECOG 2-4) and 30 B symptoms. The PGIL localization was gastric in 31 cases and 29 had a low grade malignant lymphoma. B phenotype was demonstrated in 98% and 22 patients presented advanced stages (IIE2-IV). Treatment was radical surgery followed by intensive chemotherapy in 32 cases, intensive chemotherapy alone in 17, and surgical resection in 3. CR was obtained in 34 patients and 6 of them relapsed. The projected DFS from CR at 9 years was 72% and OS was 26%. CR and survival were not influenced by PGIL localization and treatment type. The main unfavourable prognostic factors were advanced stage (CR and OS), B symptoms (DFS and OS) and advanced ECOG score (CR, DFS and OS). Previous HIV infection had an independent prognostic influence on both CR and OS. CONCLUSIONS In patients with PGIL, the achievement of CR, DFS and survival have been independent of the type of eradicative treatment used. Performance status, B symptoms and clinical stage have been the main prognostic factors. HIV infection carried an independent prognostic significance.

Abstract
Although primary ocular lymphomas may be found in the conjunctiva, eye lids and lacrimal glands, the majority nevertheless occur in the orbit. Only a few cases of primary conjunctival lymphoma have been described in the literature. A 68-year-old man presented with a painless swelling of the epibulbar conjunctiva of the right eye. A diffuse lymphoid infiltrate consisting of small-sized lymphoid cells with the morphology and distribution characteristics of mucosa-associated lymphoid tissue was observed. Immunohistological study demonstrated the B lymphocyte lineage of tumor cells and Bcl-1 and bcl-2 rearrangements were negative. After clinical staging including thoracic, abdominal, brain and orbital CT scans, fiberoptic gastroscopy and bone marrow biopsy, no other foci of this lymphoma were found. Radiation therapy was given and the patient currently remains free of lymphoma 30 months after diagnosis.

Abstract
BACKGROUND To evaluate the degree of satisfaction of the resident physicians in an university hospital by the election of the speciality and the hospital, after the takeover of the workplace and in the course of their period of residence. SUBJECTS AND METHODS An anonymous questionnaire was distributed to the 164 residents of the hospital to know the concordance between the initial expectations of the residents and the degree of current satisfaction, about the specialty and the chosen hospital. RESULTS 149 out of 164 residents (90.8%) answered the survey. In what is referring to the elected speciality, 57% (85 residents) expressed to be satisfied or very satisfied by their election; 22% (33 residents) felt indifferent, and 21% (31 residents) were unsatisfied or very unsatisfied. In what concerns to the chosen hospital, 43% (64 residents) were satisfied or very satisfied; 29% (43 residents) indifferent, and 28% (42 residents) were unsatisfied or very unsatisfied. With respect to the degree of satisfaction by the exercise of the profession at the moment of accomplishing the survey, 98% (143/149) of the residents answered, and of these, 30% (43 residents) expressed to be satisfied or very satisfied; 28% (40 residents), indifferent, and 42% (60 residents), unsatisfied or very unsatisfied. In the degree of satisfaction influenced in a statistically significant way the group of speciality chosen (medical, surgical or central services) after the examination and the moment of accomplishing the survey; the number of order of the residents examination; to have or not to have a speciality wished before of the residents examination, and the year of residence underway. CONCLUSIONS The degree of satisfaction of the resident physicians by the election of the speciality and of the hospital is relatively low. This fact outlines the suitability of the election system of the specialty.

Abstract
Invasive tracheobronchial aspergillosis is an uncommon form of Aspergillus lung infection observed in immunocompromised patients. A 43-year-old patient diagnosed with acute lymphoblastic leukemia presented prolonged fever and hemoptysis during remission induction chemotherapy. The bronchoscopic examination showed pale mucosa with multiple raised white-colored nodules of 3 to 5 millimeters in diameter in all the bronchi. Hyphae of Aspergillus sp were observed in the biopsy of one of the nodules and in the examination of the bronchoalveolar lavage. Despite amphotericin B therapy, the patient developed bilateral necrotizing pneumonia and multiple abscesses in the brain and in the thyroid gland, and died. From a review of the literature in the Medline database, four similar cases (two in AIDS patients, one in lymphoma and the remaining case in an acute myeloid leukemia patient) have been reported.

Abstract
Spinal cord compression is an infrequent event in patients with non-Hodgkin's lymphomas (NHL) and early diagnosis and therapy are required. The main clinical and histologic characteristics as well as the response to therapy in 10 NHL patients with spinal cord compression diagnosed at a single center in a 7-year period are referred. The main initial clinical manifestations were pain in dorsal or lumbar regions (5 cases) and paraparesia or paraplegia (5 patients). Infection by human immunodeficiency virus (HIV) was present in four cases. In 8 patients spinal cord compression was the initial manifestation of NHL. Pathologic diagnosis showed intermediate or high-grade lymphoma in 8 out of 10 cases and immunologic phenotype was B-cell in all cases. Laminectomy followed by radiation therapy and chemotherapy was performed in 4 cases, radiotherapy and chemotherapy in two, isolated chemotherapy in 3 and radiation therapy was administered to the remaining case. Complete response was observed in 4 cases and 6 cases were resistant to treatment. No patient with HIV infection responded to treatment. Six patients had died, median survival time for the whole series being 4 months, and the actuarial probability of survival was 40% at the first year.

Abstract
Acute myeloid leukemia (AML) is infrequent in patients with human immunodeficiency virus (HIV) infection. Among AML, acute promyelocytic leukemia (APL) has been rarely described in such patients, with only one case being published. We report a 30 years-old intravenous drug abuser HIV-infected male with APL who attained complete clinical, morphological, and molecular remission after differentiation therapy with all-trans-retinoic acid (ATRA) followed by intensive chemotherapy. The results of treatment in this patient and in other AML published cases suggest that therapy for AML should not be modified because of HIV infection if patients have an adequate performance status.

Abstract
BACKGROUND Hemopoietic progenitor cell transplantation (HPCT) is acquiring an increasing role in the therapy for a variety of disorders. In this study, main characteristics and results of HPCT along 20 years are analyzed from the experience of Postgraduate School of Hematology "Farreras-Valentí" at the Hospital Clínic in Barcelona. PATIENTS AND METHODS Six-hundred ninety-five patients transplanted between June 1976 and January 1996 were analyzed. Median age (range) were 33 (4-63) years. The following aspects were considered: donor type, source or progenitor cells, type of disease and disease-stage at transplantation, transplant related mortality and survival. RESULTS A total of 714 HPCT were performed (448 allogeneic, 13 isogeneic, 253 autogeneic). Allogeneic HPCT were from an HLA-identical sibling in 408 cases, from other familial donors in 10, and from non-familial donors in 30. Most HPCT from non-familial donors (93%) were performed during the last five years of the study (1991-1995). The source of hemopoietic progenitor cells was bone marrow in 625 instances (88%), peripheral blood in 88 (12%), and fetal liver in one. During more than 15 years, the only source of progenitors was the bone marrow; in contrast, in the last 3 years (1993-1995) transplants using peripheral blood were predominant. Main indications for HPCT were the following: acute leukemias (n = 387) (54%), chronic leukemias (n = 134) (19%), severe aplastic anemia (n = 58) (8%), lymphomas (n = 80) (11%), multiple myeloma (n = 39) (5%) and myelodysplastic syndromes (n = 14) (2%). In patients with hematological malignancies (n = 656), HPCT was performed in first complete remission or in first chronic phase in 321 instances (49%), in subsequent remissions in 144 (22%), and in more advanced stages in the remaining 191 (29%). In the more recent years, a progressive decrease in the number of HPCT for acute leukemia or aplastic anemia was observed, contrasting with an increase in transplants for lymphoma, multiple myeloma and myelodysplastic syndromes. Of note, a significant decrease in transplant related mortality was evident along the years, both after autogeneic HPCT (21% during 1985-1992 and 6% thereafter) (p = 0.001) and after allogeneic transplantation (54%, 44%, and 20% during the periods 1976-1984, 1985-1992 and 1993-1995, respectively) (p = 0.004). The fact translated into an increase in the actuarial probability of survival after allogeneic HPCT (25%, 33% and 58% in the three mentioned periods, respectively) (p = 0.0003), and after autogeneic HPCT (33% in the interim 1985-1992, and 55% in the period 1993-1995) (p = 0.001). CONCLUSIONS During the last 20 years, HPCT has significantly evolved in aspects such as type of donor, source of progenitor cells and indications. Remarkably, a progressive decrease in transplant related mortality has been observed translating into a improvement in survival after the procedure.

Abstract
BACKGROUND enzymatic polymorphisms affecting the metabolic disposition of xenobiotics may modulate the rate of activation or deactivation of carcinogens and other toxic environmental chemicals. Hence, these polymorphisms may influence the risk of suffering some types of cancer and other degenerative diseases that are incompatible with extreme longevity. AIMS to establish the distribution of three well known enzymatic polymorphisms that affect the CYP2D6, NAT-2 and CYP2E1 genes and the activity of their enzymatic gene products, involved in the disposition of many xenobiotics, in a group of nonagenarians and in much younger controls. PATIENTS the three genotypes were determined in 41 nonagenarians (10 males, mean age 92.2 years, range 90-98) free of known malignancies or neurodegenerative diseases. The control groups comprised 217 healthy volunteers (128 males, mean age 36.3 years; SD, 12.7) for the CYP2D6 and NAT2 genotypes and 137 (116 males, mean age 32 years; SD, 18.8) for the CYP2E1 genotype. METHODS after extraction of DNA from white blood cells, polymerase chain reaction and restriction fragment polymorphism methods were used to identify the allelic variants of the three genotypes. RESULTS we found no qualitative or quantitative difference in the mutations underlying the three genetic polymorphisms studied, nor in the expected enzymatic phenotypes. Instead, a close parallelism exists between advanced age and younger groups. CONCLUSION longevity does not seem to be related to any special configuration of these three polymorphic traits. Comparisons with younger controls may be adequate when studying the distribution of these polymorphisms in diseases affecting old people. No genetically determined differences in the activation of drugs metabolized by these enzymes are to be expected in very old people.

Abstract
The purpose of this study has been to refer the main clinico-biologic characteristics, the evolution and the response to therapy in 6 patients with acute myelomonocytic leukemia with eosinophilia and inversion of chromosome 16 (AML4Eo inv[16]) belonging to a series of 92 patients with acute myeloblastic leukemia diagnosed in a single hospital between 1987 and 1995. The main clinical manifestations were anemic syndrome and hemorrhage. Anemia and thrombocytopenia were present in all cases, high white blood cell count in 4, monocytosis in 5 and eosinophilia in one. Bone marrow aspirate showed myeloid and monocytic blast infiltration (43-62%), eosinophilia (5-19%) and atypical monocytic precursors (6-18%). Induction therapy consisted in one or two cycles of daunorubicin (or idarubicin), cytosine arabinoside and etoposide, followed by two cycles of consolidation treatment, the first with mitoxanthrone and cytosine arabinoside and the second with amsacrine and cytosine arabinoside. One patient died in the induction phase, while complete remission was obtained in the remaining 5. One patient died during the consolidation therapy. Allogeneic bone marrow transplant (BMT) was performed to one patient and autologous BMT to another. The first patient remains in complete remission (CR) at 68 months from diagnosis, and the second relapsed 12 months after BMT. Another patient relapsed at 13 months from diagnosis and the remaining persists in CR 13 months from diagnosis. Actuarial probabilities of CR duration and survival were 50% at 5 years. The clinico-biologic characteristics and the response to therapy of patients with AML4Eo inv(16) are similar to those referred in other series. There is a high probability of CR attainment and, probably, the relapse rate is lower than that of other subtypes of AML.

Abstract
This study characterizes the early steps of T lymphocyte activation in elderly subjects. The expression of CD69, the earliest inducible antigen which appears with T lymphocyte activation, was assessed in T cells cultured with medium, anti-CD3 or PMA. The proliferative responses of T cells stimulated through CD69 and CD3 pathways were also studied. Donors included 31 healthy elderly [age mean (SD) 80(8) years] and 33 healthy young [age 30(5) years] subjects. In elderly people, the expression of CD69 was lower in T cells cultured with medium [3.4% (1.65-5.9; 25-75 percentiles) vs. 10% (6-18), p < 0.0003] and anti-CD3 activated [28.1% (16.5-53.8) vs. 79.5% (73-89), p < 0.0002] T cells. With PMA at 10 ng/ml, CD69 expression was higher in both groups of T cells, though still lower in the aged [84.5% (70.9-94.9) vs. 99% (65.7-100), p = 0.051]. CD69 T cells expression was equal in both groups with 2 ng/ml of PMA, but the co-stimulatory responses to CD69 under these conditions and in the presence of anti-CD3 were lower in the aged (16914 vs. 28904 cpm, p < 0.02) and (6944 vs. 14370 cpm, p < 0.02) respectively. Aged T cells failed to express CD25 at the same levels of young T cells when stimulated with CD69. These results suggests an age-associated defect in the very early steps of T lymphocyte activation that might influence later stages of lymphocyte function. An alteration in the transmission of the activation signal from the cell surface to protein kinase C may play a primary role in this defect.

Abstract
BACKGROUND The aim of this study was to analyze the influence of age on the clinical and biological features as well as the results of treatment in 41 adult patients with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS The patients diagnosed with ALL from January 1989 to October 1995 in a single center were studied. Two groups of patients were analyzed based on age. The main clinical, hematologic and biochemical parameters, morphologic subtype and immunologic phenotype and the results of the cytogenetic study were analyzed. Likewise, the attainment of complete remission (CR), its duration and overall survival (OS) were also studied. Comparison of the cited variables and the results of treatment among the two groups of patients was performed. RESULTS Group I was made of 19 (11 males, 8 females) patients > or = 50 years of age (mean age 65 +/- 9 years). Group II included 22 patients (11 males and 11 females) with a mean age of 28 +/- 11 years. Significant differences were only observed between the two groups in regard to the proportion of peripheral blood blasts (p < 0.02), serum LDH values (p = 0.05) and the performance status at the time of diagnosis ( p < 0.00007). In the patients in group 1 cytogenetic alterations were more frequent (10/16 vs 4/20, p < 0.02), being mainly pseudodiploid. Complete remission was achieved in 7/16 patients in group I and in 17/22 in group II (p < 0.02). The median duration of CR was 34 and 18 months, respectively. The median OS was 7 months in group 1 and 15 months in group II with an estimated survival at 5 years of 0% in group I and 38% in group II (p < 0.05). CONCLUSIONS Patients with acute lymphoblastic leukemia over the age of 50 years have a worse general status and more cytogenetic alterations (particularly structural) than younger adult patients, presenting a lower probability of achieving complete remission and a shorter survival.
