Abstract
BACKGROUND AND OBJECTIVES To analyze in patients with de novo acute promyelocytic leukemia (APL) treated with an ATRA plus anthracyclin-based protocol if the presence of additional cytogenetic aberrations to the t(15;17) influences: 1. clinical and biological presenting features; 2. disease outcome. DESIGN AND METHODS One hundred and thirteen patients with newly diagnosed APL enrolled in the APL-96 protocol of the Spanish PETHEMA group were studied by conventional karyotyping, FISH and RT-PCR for the PML-RARa fusion. Treatment was homogeneous in all cases and consisted of anthracyclines and ATRA. RESULTS Additional chromosome aberrations were observed in 30% of cases. The most frequent secondary changes were +8 (14 cases), and abnormalities of chromosomes 9 or 3 (4 patients each), and of chromosomes 1 and 8 (3 cases each). No clinical, biological, morphological, immunophenotypic or molecular differences were observed between the group of APLs with t(15;17) alone and the group of patients with additional changes. Patients with additional changes had a higher rates of complete remission (CR) and 4-year disease-free survival (DFS) (97%, and 97%, respectively) than patients with t(15;17) alone (CR, 70% and DFS, 84%) but these differences were not statistically significant. INTERPRETATION AND CONCLUSIONS Patients with APL and additional cytogenetic abnormalities do not show different clinical, biological, morphological or molecular features as compared to patients with t(15;17) alone. The prognosis of patients with APL and t(15;17) alone and those with additional changes is similar in both groups. This study indicates that there is no rationale for administering more intensive treatment in APL patients with additional cytogenetic abnormalities receiving ATRA plus anthracycline-based chemotherapy.

Abstract
Of 167 newly diagnosed acute promyelocytic leukaemia patients, 83 patients were long (L)-form (50%), eight variable (V)-form (5%) and 76 short (S)-form (45%). The V-form and S-form groups presented a significantly higher percentage of patients with white blood cell counts > 10 x 10(9)/l (P < 0.05). The S-form cases displayed a significantly higher number of cases with M3v microgranular features (P = 0.005) and CD34 expression (P < 0.0001). There were no differences between the three isoforms in complete remission (CR) rate (overall CR 90%), but the 3-year disease-free survival was lower for V-form cases than it was for L- and S-form cases (62% vs. 94% and 89%, P = 0.056). We conclude that the V-form and S-form types are associated with some negative prognostic features at diagnosis. However, our data were only able to demonstrate an association with adverse prognosis in the V-form type and, moreover, as the number of cases was limited, needs to be confirmed in large, uniformly treated series.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the impact of early and delayed consolidation chemotherapy on the outcome of children with acute lymphoblastic leukemia (ALL) stratified according to risk groups. DESIGN AND METHODS From 1989 to 1994, 195 children (< or = 15 years old) diagnosed as having ALL (ALL-L3 excluded) in 15 Spanish hospitals entered the prospective, randomized PETHEMA ALL-89 trial. Patients were stratified into low-risk (LR), intermediate-risk (IR) and high-risk (HR) groups according to their initial features and the rate of response to induction therapy. LR-ALL patients were randomized to receive or not early consolidation chemotherapy (C-1). After receiving C-1, IR patients were randomized to receive or not delayed consolidation chemotherapy (C-2). HR patients received C-1 and C-2 chemotherapy. Standard maintenance chemotherapy was administered to all patients for 2 years. High doses of intravenous methotrexate and 12 triple intrathecal doses were given as prophylaxis against central nervous system (CNS) disease. RESULTS The mean (and standard deviation) age was 6 (4) years and 120 patients were males. Fourteen patients had early pre-B-ALL, 149 common or pre-B-ALL, and 32 T-ALL. Complete remission (CR) was attained in 189 patients (97%), 11 of whom (6%) had a slow response. Risk group stratification after CR was: LR 89, IR 50 and HR 56 patients (including a subset of 26 patients at very high risk). Ten-year event-free survival (EFS) and overall survival (OS) probabilities for the whole series were 58% (95% CI: 52-64%) and 69% (61-77), respectively, with a median follow-up of 8.7 years. Dividing the patients according to risk group, the 10-year EFS and OS probabilities in the LR group were 71% (63-79) and 86% (80-92), respectively; in the IR group 69% (57-81) and 76% (64-88), respectively, and in the HR group 30% (18-42) and 44% (32-57), respectively. For LR patients receiving C-1, EFS and OS were 79% (57-92) and 90% (82-98), respectively, versus 62% (48-76) and 66% (51-81) in patients not receiving C-1 (p= 0.06). For IR patients, EFS and OS were significantly improved in those receiving early and delayed consolidation (EFS 87% (74-88) vs. 52% (41-70), and OS 92% (87-97) vs. 61% (51-71)(p=0.036). Prognostic factors for EFS identified in multivariable analyses were: age >10 years in the LR group (OR 3.5, 95% CI 1.3-9.5, p=0.01), and treatment with C-2 in IR patients (OR 5.0, 95% CI 1.4-17.8, p=0.01). The CNS relapse rate was 4% for all the series (including the HR subset). Tolerance to treatment was good. INTERPRETATION AND CONCLUSIONS In this study, early consolidation seemed to improve the prognosis of children with LR-ALL, but differences in EFS were not significant. Delayed consolidation had a favorable influence on the outcome of IR-ALL. CNS preventive treatment without cranial irradiation was effective in all the groups of ALL patients.

Abstract
BACKGROUND To analyse the etiology, diagnostic methods and response to therapy in 30 episodes of pneumonia diagnosed in 17 patients with chronic lymphocytic leukemia (CLL) between 1995 and 2000. PATIENTS AND METHOD In each episode of pneumonia the following data were analysed: age, gender, treatment of CLL, antiinfectious prophylaxis, granulocytopenia, CD4/CD8 lymphocytes ratio, hipogammaglobulinemia, origin of pneumonia (nosocomial or community-acquired), localisation, respiratory insufficiency, need for mechanical ventilation, antimicrobial therapy and response. Diagnostic methods included blood and sputum cultures, fiberoptic bronchoscopy and search for antigens in urine (Legionella pneumophila serogroup 1, galactomannan, and Streptococcus pneumoniae). RESULTS Median age of the series was 60 yr. (range 50-86) and 12 patients were male. Chlorambucil and prednisone were used in 13 cases and fludarabine in 8. Granulocytopenia was present in 14 episodes, hypogammaglobulinemia was seen in 22 and CD4/CD8 ratio was lower than 1 in 8 out of 14 evaluable cases. Etiology of pneumonia was established in 16 episodes (53%). Fiberoptic bronchoscopy was the most useful technique (83% of positive diagnoses) followed by blood cultures (38%). Two patients were diagnosed of aspergillosis at autopsy. Pneumococcus was the most frequent agent (5 cases) followed by Pseudomonas aeruginosa (4), Pneumocystis carinii (2) and Aspergillus fumigatus (2). One out of the two patients with P. carinii pneumonia had received fludarabin and the remaining was treated with prednisone for long time. Ten patients (30%) had died: P. aeruginosa (3 cases), P. carinii (2), A. fumigatus (2), Mycobacterium xenopi (1), and unknown microorganism (2). CONCLUSIONS In this series of CLL patients the frequency of etiologic diagnosis of pneumonias was good. Pneumococcus was the most frequent microorganism. Pneumonias caused by opportunistic microorganisms were associated to the treatment with fludarabin or prednisone and were associated to a high mortality rate.

Abstract
BACKGROUND To analyse the results of the treatment with 2-chlorodeoxyadenosine (2CdA) in 9 patients with refractory or relapsed Langerhans cell histiocytosis (LCH) tracted in 8 Spanish hospitals between 1993 and 1999. PATIENTS AND METHOD In the 9 patients the following data were recorded: age, sex, organ involvement by LCH, first treatment and response, dose, number of cycles and schedule of administration 2CdA, response to 2CdA treatment, toxicity, disease-free survival (DFS) and overall survival (OS). RESULTS Median age was 25 years (range, 6-63). All patients had multiorganic involvement by LCH, with severe organ dysfunction in 4. 2CdA was administered as second line treatment in 7 cases and as third line in 2. The 2CdA dose was 0.1 mg/kg per day during 5 days in the majority of patients, and interval between cycles was 4 weeks. In 2 cases a complete remission (CR) was achieved and 4 cases attained a partial remission (PR) (overall response rate 66%). The main toxicity was hematologic, with neutropenia grade > 2 in 5 cases and thrombocytopenia > 2 in 5. Four patients had infections, with fatal evolution in one of them. After a median follow-up of 8 months (range 2-17), 2 patients remained in CR (12 months both), 4 in PR (range 2-12 months) and one had active disease (17 months). The other two died due to progressive disease and Aspergillus spp. sepsis, respectively. The actuarial probabilities of DFS and OS were 58% (95% CI, 38-78%) and 71% (95% CI, 54-88%), respectively. CONCLUSIONS 2CdA is an active drug for patients with refractory or relapsed LCH, and its main toxicity is myelosuppression. The usefulness of 2CdA, isolated or in combination with other drugs, in patients with refractory or relapsed LCH must be assessed in controlled studies.

Abstract
Combined highly active anti-retroviral therapy (HAART) with protease and reverse transcriptase inhibitors has modified the natural history of opportunistic infections and neoplasms in human immunodeficiency virus (HIV)-infected patients. We analysed the influence of HAART on the response to treatment and survival in a series of 58 patients with acquired immune deficiency syndrome (AIDS)-related non-Hodgkin's lymphoma (NHL) treated with CHOP (cyclophosphamide, hydroxydoxorubicin, vincristine and prednisone). Two groups of patients were included: (i) forty-one patients diagnosed with NHL between 1988 and 1996 who were not treated with HAART; (ii) seventeen patients diagnosed since 1996, who were receiving or commenced HAART when NHL was diagnosed. The response rate to CHOP was higher in group 2 (13 out of 17 cases; 75%) than in group 1 (14 out of 41 cases; 34%) (P = 0.003). The 2-year probability of event-free survival (EFS) [95% confidence interval (CI)] for group 1 was 0.5 (0.24-0.74), whereas for group 2 it was 0.85 (0.61-0.90) (P = 0.024). The lymphoma-free survival (LFS) was also significantly different for both groups (2-year LFS probability 0.53 vs. 1.0, P = 0.04). The median (95% CI) overall survival (OS) for group 1 was 7 months (range, 3-10.8 months), whereas it was not reached in group 2 (P = 0.0015). In the multivariate analysis for remission attainment, the only variables with a higher probability to achieve complete remission (CR) were HAART (P = 0.01) and International Prognostic Index score 1 (P = 0.02). The only statistically significant variable in the multivariate analysis for EFS was HAART (P = 0.049) and the variables with prognostic value for OS in the multivariate analysis were B symptoms (P = 0.01) and HAART (P = 0.003). Patients with AIDS-related NHL treated with CHOP and HAART had a higher CR rate than those treated only with CHOP. In this study, HAART was an independent prognostic factor for CR, OS and EFS in patients with AIDS-related NHL.

Abstract
A 83 year old diabetic woman was admitted to our hospital with the diagnosis of subacute inferoposterior myocardial infarction. Four days later physical examination revealed a new systolic murmur at the left sternal border and apex. Transthoracic echocardiogram showed inferoposterior akinesis and a dissection tract in the posterior wall of the left ventricle arising from the distal to mid-segment with an entrance tear of 7 mm. Doppler color showed a systolic jet with a mosaic flow pattern inside the right atrium which appeared to originate in the coronary sinus. Transesophageal echocardiogram confirmed the intramyocardial dissection of the posterior wall and its communication with the coronary sinus, and identified the latter as the origin of the mosaic flow inside the right atrium. Medical treatment was initiated and the patient has been followed up for two years. The diameter of the entrance tear remains unchanged although the dissection tract and coronary sinus have enlarged, no significant enlargement has been observed in the right chamber on follow up.

Abstract
This study aims to establish the relative effectiveness and safety of low molecular weight heparin in elderly patients with venous thrombosis in order to find an alternative to oral anticoagulant therapy with less bleeding complications in the long-term treatment of deep venous thrombosis (DVT). One hundred consecutive elderly patients (>75 years old) with venographically demonstrated proximal DVT were included in a randomized trial. All patients were treated for ten days with adjusted doses of intravenous heparin. Informed consent was obtained and on the eight day, patients were randomly allocated to receive acenocoumarol (INR 2.0-3.0) or subcutaneous enoxaparin (4000 anti-Xa units once a day) for three months. All patients were followed-up clinically and venographically for a one year period. The results were analyzed with Fisher's exact test or chi-square test as appropriate. During the treatment and surveillance period, 6 of the 50 patients (12%) who received acenocoumarol and 8 of the 50 patients (16%) who received enoxaparin had new episodes of venous thromboembolism confirmed by objective testing (p = 0.6; 95% CI for the difference: -19.5 to 11.5). Hemorrhagic complications occurred in six of the 50 patients (12%) who received acenocoumarol and in one (2%) of those on enoxaparin (p = 0.1; 95% CI for the difference: -1.8 to 21.8). Vertebral fractures developed in 2 patients (4%) in the enoxaparin group (p = 0.5; 95% CI for the difference: -11.4 to 3.4). These results show that fixed dose enoxaparin seems to be effective and safe in the long-term treatment of proximal DVT in the elderly. In comparison with oral anticoagulants, the findings are inconclusive due to the wide confidence intervals for differences between outcomes, however they suggest that the former may have less bleeding complications with similar efficacy.

Abstract
Since the introduction of user fee systems in the government health facilities of most African countries, which shifted part of the burden of financing health care onto the community, affordability of basic health care has been a much discussed topic. It is sometimes assumed that in areas where high levels of spending for traditional treatments are common, people would be able to pay for basic health care at governmental facilities, but may not be willing to do so. However, examining willingness to pay and ability to pay in the broader context of different types of illness and their treatment leads us to a very different conclusion. In the course of a medical-ethnographic study in south-eastern Tanzania, we found evidence that people may indeed be willing, but may nevertheless not be able, to pay for biomedical health care--even when they can afford costly traditional medicine. In this article, we suggest that the ability to pay for traditional treatment can differ from ability to pay for hospital attendance for two main reasons. First, many healers--in contrast to the hospital--offer alternatives to cash payments, such as compensation in kind or in work, or payment on a credit basis. Secondly, and more importantly, the activation of social networks for financial help is different for the two sectors. For the poor in particular, ability to pay for health care depends a great deal on contributions from relatives, neighbours and friends. The treatment of the 'personalistic' type of illness, which is carried out by a traditional healer, involves an extended kin-group, and there is high social pressure to comply with the requirements of the family elders, which may include providing financial support. In contrast, the costs for the treatment of 'normal' illnesses at the hospital are usually covered by the patient him/herself, or a small circle of relatives and friends.

Abstract
Preliminary independent reports of the Italian GIMEMA and the Spanish PETHEMA trials for newly diagnosed acute promyelocytic leukemia (APL) indicated a similarly high antileukemic efficacy in terms of complete remission and disease-free survival rates. To better investigate these studies and the prognostic factors influencing relapse risk, this study analyzed the updated results of 217 patients with PML/RAR alpha-positive APL enrolled in GIMEMA (n = 108) and PETHEMA (n = 109). All patients received identical induction (AIDA schedule) and maintenance. For consolidation, GIMEMA patients received 3 courses including idarubicin/cytarabine, mitoxantrone/etoposide, and idarubicin/cytarabine/thioguanine, whereas PETHEMA patients received the same drugs and dose schedule of idarubicin and mitoxantrone with the omission of nonintercalating agents. Depending on whether molecular relapses were classified as censored or uncensored events, the 3-year Kaplan-Meier estimates of relapse-free survival (RFS) for the combined series were 90 +/- 2% and 86 +/- 2%, respectively. Minor differences observed between the 2 patient cohorts were negligible. Multivariate regression analysis of RFS showed that initial leukocyte (WBC) and platelet counts were the only variables with independent prognostic value. The resulting predictive model for RFS demonstrated its capability of segregating patients into low-risk (WBC count </= 10 x 10(9)/L, platelet count > 40 x 10(9)/L), intermediate-risk (WBC count </= 10 x 10(9)/L, platelets </= 40 x 10(9)/L), and high-risk (WBC count > 10 x 10(9)/L) groups, with distinctive RFS curves (P <.0001). The conclusions are that omission of nonanthracycline drugs from the AIDA regimen is not associated with reduced antileukemic efficacy and a simple predictive model may be used for risk-adapted therapy in this disease.

Abstract
BACKGROUND AND OBJECTIVE It has been established that cytogenetic findings at the time of diagnosis of acute myeloid leukemia (AML) are powerful prognostic indicators. Pericentric inversion of chromosome 16 and translocation t(16;16) resulting in chimeric fusion of CBFB and MYH11 genes are typically seen in the M4-Eo FAB classification subset of AML and are associated with low-risk disease. These subtle chromosomal abnormalities may be difficult to detect in poor-quality metaphase preparations and if missed could lead to incorrect assignment to risk groups and influence the therapy decision-making process. DESIGN AND METHODS We prospectively studied, at diagnosis, 10 patients with AML-M4 Eo by cytogenetics and fluorescent in situ hybridization (FISH) with two cosmids (36 and 40). As a control group, 7 patients (5 with a diagnosis of AML other than M4 Eo and two cases of reactive eosinophilia) were analyzed. In addition reverse transcriptase chain reaction (RT-PCR) studies were carried out in 6 cases. RESULTS Karyotypic analysis detected the inv(16) in all but one of the patients with M4-Eo while none of the control cases showed any abnormality on chromosome 16. FISH studies showed that all 10 patients had abnormalities on chromosome 16; the patient with normal karyotype showed an inv(16) by FISH, while a case with inv(16) by cytogenetics had a t(16;16) by FISH. RT-PCR demonstrated amplification of the CBFB/MYH11 product in all cases analyzed. INTERPRETATION AND CONCLUSIONS In patients with M4Eo and rearrangements of chromosome 16, FISH studies may afford more complete information than conventional cytogenetics and can be an alternative to RT-PCR studies.

Abstract
Posttransplantation T cell lymphomas (PTTLs) are rather unusual, and their etiology remains unclear. We describe a case of Epstein-Barr virus (EBV)-associated small bowel T cell lymphoma in a patient 5 years after kidney transplantation. EBV was detected in a biopsy sample by in situ hybridization, immunohistochemical staining, and polymerase chain reaction analysis. Eight previously reported cases of EBV-associated PTTL are reviewed, in which special attention is paid to the methods used for assessing EBV. This case of EBV-associated PTTL is believed to be the most completely studied from the point of view of the methods used for detection of EBV. The prognosis of PTTL is poor, but it has been reported that therapeutic approaches can be successful if they are given early in the course of the illness. Therefore, it is necessary to improve the diagnosis PTTL and to assess the precise involvement of EBV in posttransplantation lymphoproliferative disorders.

Abstract
BACKGROUND In spite of not being considered as an AIDS defining illness, Hodgkin's disease (HD) has specific clinical and biological features in HIV-infected patients. PATIENTS AND METHODS Study of clinicopathologic and analytic characteristics, Epstein-Barr virus (EBV) detection (polymerase chain reaction), and prognosis in 15 patients with HD and HIV infection. RESULTS Thirteen patients had B symptoms, 10 extranodal involvement and 12 advanced HD. The most frequent histologic subtypes were mixed cellularity (6) and lymphocyte depletion (6). The mean (SD) of CD4 lymphocytes was 0.10 (0.08) x 10(9)/l. The presence of EBV in lymph node biopsy was demonstrated in 3 out of 4 patients investigated. Complete remission (CR) was achieved in 7 out of 14 treated cases (50%), the median overall survival was 26 months and the 2 year event-free survival probability was 60%. CONCLUSIONS In HIV-infected patients, HD presents in advanced stages, unfavourable histologic subtypes, frequent extranodal involvement and B symptoms. The prognosis is poor, mainly because of a low CR rate.
