RESUMO

OBJECTIVE: The authors had for aim to define the threshold of nephrotoxicity before switching to other antifungal treatment in hematological patients treated by conventional amphotericin B (AmB) as an empiric antifungal treatment. DESIGN: A prospective randomised multicenter study was made on 32 neutropenic hematological patients receiving conventional AmB for empirical antifungal treatment. The patients were randomised after a greater than or equal to 30% increase of serum creatinine (sCr). Patients in the early-switch group received liposomal AmB just after randomisation and patients in the late-switch group received liposomal AmB only when serum creatinine increase was greater or equal to 100% or sCr reached 170mumol/L. RESULTS: Thirty-one patients were analysed: 16 patients in the early-switch group and 15 patients in the late-switch group (seven switched to liposomal AmB and eight continued conventional AmB treatment). The mean age of patients was 48 years and 68% were men. The most frequent underlying haematological malignancy was acute leukemia (94%). In the late-switch group, the degradation of renal function continued after randomisation contrary to the early-switch group: median variations of calculated sCr clearance in early- and late-switch groups were -16.8 and -1.5%, respectively (P=0.03). Moreover, an early switch was cost-effective with a sCr lower duration of hospitalisation in comparison with a late switch. CONCLUSIONS: This randomised trial suggests that an early switch to Liposomal AmB improves and preserves renal function in comparison with a late switch.

RESUMO

Our objective was to study the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) for Shwachman-Diamond Syndrome (SDS). Among 71 SDS patients included in the French Severe Chronic Neutropenia Registry, 10 received HSCT between 1987 and 2004 in five institutions. The indications were bone marrow failure in five cases, and myelodysplastic syndrome (MDS) or leukemia in five cases. The median follow-up of patients who survived without relapse is 6.9 years (3.1-16.8 years). The conditioning regimen consisted of a busulfan-cyclophosphamide combination (n=6) or total body irradiation plus chemotherapy (n=4). Six patients received stem cells from unrelated donors and four from identical siblings. Engraftment was complete in eight patients and unassessable in two patients. These latter two patients died of infections 32 and 36 days after HSCT, with grade IV graft-versus-host disease and multiorgan dysfunction. A third patient died from an acute respiratory distress syndrome 17 months after HSCT with progressive granulocytic sarcoma. One patient had an MDS relapse 4 months after HSCT and died 10 months later. The overall 5-year event-free survival rate is 60+/-15%. We conclude that HSCT is feasible for patients with SDS who develop bone marrow failure or malignant transformation.

RESUMO

A hundred and eight patients less than 60 years old with de novo acute myeloid leukemia were treated between 1982 and 1994 by protocols including final intensification with a transplant using autologous bone marrow purged by mafosfamide in first remission in the absence of an HLA-matched sibling donor available for allograft. From 1989, we attempted to improve tumor control by using high-dose anthracyclines in induction, by increasing from one to two the number of consolidation courses pre-transplant and by introducing intermediate doses of cytarabine in the first consolidation course. The CR rate was 77% (33/43) before 1989 and 90% (59/65) after 1989 (P = 0.06). Forty-five out of the 59 patients (76%) who achieved CR after 1989 could undergo bone marrow grafting in CR1 vs 16/33 (48%) before 1989 (P = 0.01). In spite of the higher proportion of patients above 50 years after 1989 (32%) toxicity was mild and an adequate graft was obtained more frequently after one collection. The principal factor relating to improvement in graft feasibility was the post-1989 modification of induction and consolidation regimens. This improvement in graft feasibility was associated with a better disease-free survival (DFS) (48 +/- 7% vs 32 +/- 8%, P = 0.04) and overall survival (OS) (53 +/- 6% vs 30 +/- 7%, P = 0.007) at 5 years. By multivariate analysis four factors were associated with overall survival (OS): karyotype, white blood cell count at diagnosis, treatment regimen and bone marrow grafting in CR1. This global approach should be prospectively compared with intensive chemotherapy.

RESUMO

A 35 y old woman with severe and progressive systemic lupus erythematosus (SLE) received high-dose chemotherapy followed by a T cell depleted autologous stem cell transplantation. Peripheral blood stem cell were mobilised with Cyclophosphamide 4.5 g/m2 followed by Granulocyte-Colony Stimulating Factor (G-CSF). A CD34 positive selection provided a 3 log T cell depletion. High-dose immunosuppression consisted of the BEAM regimen. The purified autograft was reinfused on day 0. In the post transplant period, hemopoietic growth factors, G-CSF, Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) and Erythropoietin, were administered, engraftment was rapid. Both the mobilisation and the transplant procedures were easily performed and well tolerated. One year later, the patient is in clinical remission. The ANA and anti-SSA-antibodies were undetectable at 1 and 6 months after intensification, but reappeared at low levels at 9 months. Corticosteroid requirement has gradually decreased. In conclusion, we report here the favourable evolution of a patient with a severe SLE, who clinically improved with high-dose immunosuppressive therapy and autologous stem cell transplantation, and showed a 9 month serological remission.

RESUMO

Progressive multifocal leucoencephalopathy is an opportunistic JC virus-related pathology occurring in immunocompromised patients. We report a case of severe cellular immunodeficiency in a patient who underwent autologous bone marrow transplantation for acute myeloblastic leukemia, and who subsequently developed progressive multifocal leucoencephalopathy, an unusual pathology in this context. Progressive multifocal leucoencephalopathy was preceded by a peripheral demyelinating neuropathy. We discuss the possible link between these two neuropathies, the possible aggravation or activation from CMV infection, as well as the possible contribution of bone marrow purging in the resultant cellular immunodeficiency.

RESUMO

Several prospective randomized trials in acute myelocytic leukemia (AML) documented a lower relapse rate with autologous bone marrow transplantation (ABMT) than with conventional chemotherapy. However, they also identified some transplant difficulties, such as failure to collect sufficient numbers of stem cells, slow kinetics of engraftment, and a high transplant-related mortality that diminished or negated positive impact on overall survival. Data for ABMT are inconclusive in acute lymphocytic leukemia (ALL) in adults. We retrospectively analyzed patients with acute leukemia autografted with marrow purged with mafosfamide after January 1983 in our institution. The population comprised 229 consecutive patients; 165 with AML [123 in first remission (CR1), 32 in second remission (CR2)]; 61 with ALL (46 in CR1, 4 in CR2); and 3 with undifferentiated acute leukemia. All patients were autografted with marrow purged with mafosfamide. Mafosfamide was given at a constant dose of 50 microg/mL in 103 and adjusted individually to produce a CFU-GM LD 95 (5% residual CFU-GM post purging) in 126. The outcome was analyzed for correlation with patient characteristics, the disease including cytogenetics, and the graft itself. Prognostic factors identified by multivariate analysis were used to derive a prognostic classification. Patients receiving higher doses of marrow submitted to purging (>5.46 x 10(4) CFU-GM/kg) experienced a lower treatment-related mortality (RR = 0.11, p = 0.005) and a higher leukemia-free (RR = 0.5, p = 0.005) and overall survival (RR = 0.4, p = 0.001). Patients receiving <0.004% CFU-GM of marrow actually infused post purging had a lower relapse rate (RR = 0.51, p = 0.003). Modeling of prognostic groups identified good-, intermediate-, and poor-risk categories. Patients receiving a stem cell dose evaluated before purging of >5.46 x 10(4) CFU-GM/kg and doses actually infused post purging of < or =0.02 x 10(4)/kg had a treatment-related mortality of only 2+/-2%, a leukemia-free survival of 70%, and an overall survival of 77+/-7% at 10 years. In this study of autotransplantation for acute leukemia using mafosfamide-purged marrow, the stem cell dose used for purging and the intensity of purging were the most important factors predicting outcome.

RESUMO

263 patients (median age 65+/-10 years) with multiple myeloma were treated with cyclophosphamide-prednisone. Out of this cohort, 103 patients had progressive disease and were randomly assigned to either VAD (vincristine, doxorubicin, dexamethasone; 50 cases) or VMBCP (vincristine, BCNU, cyclophosphamide, melphalan and prednisone; 53 cases). There were no statistical differences between the two groups with the respect to clinical, biological and radiological parameters. There was no difference in survival between the VAD and VMBCP groups. The 4 months response rate was similar in the two groups (50% VAD, 56% VMBCP). With multivariate analysis for survival (Cox model), two factors had a statistically significant impact: Karnofsky index (> 60) and albuminaemia (< 34 g/l). With both Karnofsky index > 60 and albuminaemia > or = 34 g/l, the median survival was 29 months v 2 months with a Karnofsky index < or = 60 and albuminaemia < 34 g/l (P<0.05). In conclusion, VAD or VMBCP had similar activity for salvage treatment in MM refractory or relapsing to first-line treatment with cyclophosphamide-prednisone.

RESUMO

Bone marrow (BM) samples from 24 patients with acute leukaemia (AML 17, ALL seven) in first complete remission were compared to samples from 10 normal donors with regard to their content in long-term culture-initiating cells (LTC-IC) as assessed by a limiting dilution assay and the clonogeneic capacity of these cells, in order to determine whether remission marrow cells displayed any specific defect at the primitive stem cell level. The frequency of LTC-IC in the whole patient group was 1 in 3487 +/- 3125 mononuclear cells (MNC) as compared to 1 in 794 +/- 492 MNC in normal controls (P = 0.0009), with no difference between AML and ALL. Moreover, the clonogeneic capacities were 2.66 +/- 0.7 (range 1.8-1.6) and 4.0 +/- 1.6 (range 2.2-7.9) CFC per LTC-IC in patients and controls respectively (P = 0.0015). These quantitative and qualitative defects were aggravated by treatment with mafosfamide at a dose of 50 microg/10(7) MNC/ml, where the mean recovery of LTC-IC after in vitro purging was 42%. In nine patients autografted with purged marrow following high-dose radiochemotherapy, no correlation could be detected between the dose of LTC-IC (mean 6742 +/- 7877/kg) and the kinetics of recovery of haemopoiesis. We concluded that, in acute leukaemia patients in complete remission, the presumably normal residual stem cell pool was not only quantitatively diminished but also qualitatively altered in its capacity to give rise to clonogeneic progenitor cells.

RESUMO

PURPOSE: To analyze retrospectively survival and prognostic factors of patients with non-Hodgkin's lymphoma (NHL) autografted from 1979 to 1995 in a single institution. PATIENTS AND METHODS: A total of 120 patients, 64 with aggressive and 56 with low-grade NHL, were autografted. The carmustine (BCNU), etoposide, cytarabine, and melphalan (BEAM) regimen was used in 104. The autograft was marrow in 101 patients. Marrow was purged in vitro by mafosfamide for 63 patients (adjusted dose [AD] in 32; unique dose [UD] in 31); 27 patients received a CD34+-selected graft. Following intensification, 45 patients received additional radiotherapy on previous sites of involvement. RESULTS: Outcome at 5 years for patients transplanted with low-grade NHL in first complete remission (CR1), in first partial remission (PR1), and in second complete remission (CR2) or beyond showed an event-free survival (EFS) of 75% +/- 12%, 46% +/- 18%, and 57% +/- 24%, a relapse incidence (RI) of 21% +/- 12%, 49% +/- 19%, and 43% +/- 25%, and a transplant-related mortality (TRM) of 5% +/- 5%, 10% +/- 7%, and 0%, respectively. For patients with aggressive NHL transplanted in CR1, in PR1, in CR2 or beyond, and in resistant relapse or in primary refractory disease, the EFS was of 73% +/- 9%, 58% +/- 19%, 29% +/- 16%, and 10% +/- 9%, the RI 22% +/- 9%, 14% +/- 9%, 77% +/- 18%, and 66% +/- 20%, and the TRM 6% +/- 6%, 32% +/- 21%, 11% +/- 10%, and 71% +/- 22%, respectively. In patients autografted upfront in first remission, additional radiotherapy was associated with a higher EFS, in univariate (P = .03) and multivariate analysis (P = .02, relative risk [RR] = .021). The role of graft purging with mafosfamide on the outcome reflected by the dose of colony-forming unit-granulocyte-macrophage (CFU-GM) per kilogram infused postpurging was assessed by univariate analysis: patients in first remission who received lower doses of CFU-GM had a lower RI and a higher EFS. CONCLUSION: This retrospective analysis suggests that marrow purging and posttransplant radiotherapy improve the outcome of patients with NHL autografted in first remission.

RESUMO

We report on six cases of unrelated UCB transplant in adult patients with hematological malignancies: three chronic myelocytic leukemias and three acute leukemias. Their median age and body weight were respectively: 28 years (range 15.5-40) and 55.5 kg (range 46-90). The cord blood units were from the New York Blood Center. The median number of nuclear cells provided, evaluated before thawing, was 2.1 x 10(7)/kg (range 1 x 10(7)/kg-4.7 x 10(7)/kg). The degree of HLA disparity was 1/6: two patients, 2/6: three patients, 3/6: one patient. The patients received a pretransplant regimen including total body irradiation. They were given graft-versus-host disease prophylaxis which consisted of cyclosporin A and corticosteroids. They were all given a combination of G-CSF and erythropoietin. The median time of white blood cell and platelet reconstitution were respectively 24 days (range 12-43) and 60 days (range 23-90). All the patients had a full chimerism. A grade I acute GVHD was observed in four patients and two patients do not have any GVHD. No chronic GVHD has been observed yet. Three patients died from toxicity. Three patients are alive and well in complete remission at 2 years, 1 year and 11 months post-graft.

RESUMO

Human CD34+ selected cells are able to reconstitute hematopoiesis in patients receiving a myeloablative treatment. Although the role of reinfused tumor cells contaminating the grafts on the determination of postautograft relapses remains unclear, the major interest of CD34+ cell selection is to reduce the tumor contamination of the graft. This can be achieved if tumor cells do not express the CD34 antigen. We previously showed that this approach was effective with bone marrow (BM) collections in patients with non-Hodgkin's lymphoma (NHL). Because peripheral blood progenitor cells (PBPC) allow faster hematologic recovery than BM and are expected to contain less tumor contamination, we have compared the results of CD34+ cell selection in 35 BM and 16 PBPC from 48 patients with NHL. The PBPC were collected after a course of chemotherapy followed by granulocyte colony-stimulating factor (G-CSF) administration. The data showed that the final CD34+ cell purity achieved with PBPC was higher than with BM (medians, 70% v 50%; P = .02). The CD34+ cell recovery was also better for PBPC (medians, 42% v 24%; P = .001). Tumor contamination was assessed by detection of BCL2/JH rearrangement using polymerase chain reaction (PCR) in 38 of 48 patients (22 BM, 16 PBPC). In addition, immunoglobulin heavy chain gene (IgH) rearrangements were investigated using PCR with consensus IgH primers. At harvesting, 10 of 22 BM and two of 16 PBPC contained BCL2/JH+ cells, one of 22 BM and 14 of 16 PBPC contained abnormal IgH+ cells (one PBPC contained both BCL2/JH+ and abnormal IgH+ cells) at harvesting. However, because lymphoma tissue specimens from patients at diagnosis were not available, the malignant character of IgH rearrangements could not be confirmed by sequencing and probing with allele-specific nucleotides. After CD34+ cell selection, a reduction to below the level of detection of BCL2/JH+ cells of BM and PBPC was effective in seven of 12 informative selections. In contrast, a reduction to below the level of detection of abnormal IgH+ cells was effective in only three of 15 informative selections. However, the detection of cells with an abnormal IgH pattern in the context of chemotherapy plus G-CSF progenitor mobilization in patients with NHL and its correlation with actual tumor contamination needs further investigation.

RESUMO

Intensive chemotherapy followed by autologous bone marrow transplantation (ABMT) may provide an alternative therapy for young patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia following MDS (sAML) lacking a suitable donor. We report the results for 79 patients with MDS/sAML transplanted with autologous marrow in first complete remission (CR). Within the total group of 79, a cohort of 55 patients for whom the duration of first CR was known were compared with a matched control group of 110 patients with de novo AML. The 2-year survival, disease-free survival (DFS), and relapse rates for the 79 patients transplanted in first CR were 39%, 34%, and 64%, respectively. The relapse risk was greater than 55% for all stages and all disease categories. Patients younger than 40 years had a significantly (P = .04) better DFS (39%) than patients older than 40 years (25%). The DFS at 2 years was 28% for the cohort of 55 patients transplanted for MDS/sAML and 51% for those transplanted for de novo AML (P = .025). Relapse rates were 69% for patients with MDS/sAML and 40% for those with de novo AML (P = .007). ABMT for MDS or secondary leukemia results in a lower DFS when compared with similarly treated patients with de novo AML due to a higher relapse rate. The DFS of 28% for these patients suggests that autotransplantation may be a valuable therapy for this disease. The low treatment-related mortality rate of less than 10% supports the view that sufficient numbers of hematopoietic stem cells are present in patients with MDS to allow adequate repopulation after autologous stem-cell transplantation.

RESUMO

BACKGROUND: Cord-blood banks have increased the use of cord-blood transplantation in patients with hematologic disorders. We have established a registry containing information on the outcome of cord-blood transplantation. METHODS: We sent questionnaires to 45 transplantation centers for information on patients receiving cord-blood transplants from 1988 to 1996. Reports on 143 transplantations, performed at 45 centers, were studied, and the responses were analyzed separately according to whether the donor was related or unrelated to the recipient. RESULTS: Among 78 recipients of cord blood from related donors, the Kaplan-Meier estimate of survival at one year was 63 percent. Younger age, lower weight, transplants from HLA-identical donors, and cytomegalovirus-negative serologic results in the recipient were favorable prognostic factors. Graft-versus-host-disease of at least grade II occurred at estimated rates of 9 percent in 60 recipients of HLA-matched cord blood and 50 percent in 18 recipients of HLA-mismatched cord blood. Neutrophil engraftment was associated with an age of less than six years (P = 0.02) and a weight of less than 20 kg (P = 0.02), and it occurred in 85 percent of patients receiving 37 million or more nucleated cells per kilogram of body weight. Among 65 patients who received cord blood from unrelated donors, the Kaplan-Meier estimate of survival at one year was 29 percent. Cytomegalovirus-negative serologic status in these recipients was associated with improved survival (P = 0.03) and was the most important predictor of graft-versus-host disease (P = 0.04). Neutrophil recovery occurred in 94 percent of the patients who received 37 million or more nucleated cells per kilogram from unrelated donors. CONCLUSIONS: Cord blood is a feasible alternative source of hematopoietic stem cells for pediatric and some adult patients with major hematologic disorders, particularly if the donor and the recipient are related.

RESUMO

PURPOSE: To evaluate the impact of granulocyte-macrophage colony-stimulating factor (GM-CSF) or placebo on the durations of intravenous (IV) antibiotic use, hospitalization, neutropenia, and fever, as well as remission rates, after high-dose melphalan (HDM) without stem-cell transplantation (SCT) in patients with multiple myeloma (MM). PATIENTS AND METHODS: One hundred two patients with high-risk MM were randomized 2:1 in a prospective multicenter trial to receive 5 microg/kg/d GM-CSF (69 patients) or placebo (33 patients) starting the day after 140 mg/m2 IV melphalan for up to 21 days. RESULTS: GM-CSF significantly reduced neutropenia after HDM (median, 23.5 v 29 days; P = .0468), with a trend to reduce the duration of hospitalization (median, 32 v 38 days; P = .0841). Nevertheless, GM-CSF did not significantly reduce infectious toxicity as regards the number of days with fever (median, 5 v 3; P = .359), the number of days with IV antibiotics (median, 22 v 27; P = .14), or early deaths, with an 11.5% treatment-related mortality rate in the GM-CSF group (eight of 69 v two of 32 patients in the placebo group; P = .686). There was no difference in response rates between the two groups of patients. CONCLUSION: GM-CSF after HDM without SCT is feasible and significantly shortens neutropenia with a trend toward reduction of hospitalization duration, but does not significantly reduce the morbidity and mortality of such therapy. Thus, when intensive therapy is indicated, given that the mortality of HDM followed by SCT reported in the literature is less than 5% and patients are discharged at approximately day 15, despite the risk of contamination by clonogenic malignant cells, SCT appears to be preferable to GM-CSF after HDM.

RESUMO

Transplantation of peripheral blood progenitor cells (PBPCs) has largely replaced autologous bone marrow transplantation. The same might occur in the allogeneic setting if the favourable initial experience with allogeneic PBPCT is confirmed. We analysed all primary transplants utilizing unmodified PBPC from HLA-identical sibling donors reported to the European Group for Blood and Marrow Transplantation (EBMT) for 1994. 59 patients with a median age of 39 years received myeloablative therapy for acute myelogenous leukaemia (23 patients, acute lymphoblastic leukaemia (13), chronic myelogenous leukaemia (nine), lymphoma (seven), or other diagnoses (seven) mostly of advanced stages followed by transplantation of allogeneic PBPC. Three patients died soon after grafting, the others showed prompt haemopoietic recovery with median times to recover an absolute neutrophil count (ANC) above 0.5 and 1.0 x 10(9)/I of 15 (range 9-27) and 17d (range 10-28) respectively. Time to platelet recovery above 20 or 50 x 10(9)/I was 16 (range 9-76) and 18d (range 12-100) respectively. 27 patients (46%) developed no or mild acute graft-versus-host disease (GVIID). The incidence of moderate (grade II) disease was 27%; 24% of the patients developed severe acute GVHD (grades III or IV), 55% of patients who were alive 90d after transplantation developed chronic GVHD, the probability to develop extensive chronic GVHD was 32% (95% confidence interval 22-42) with a median follow-up of 14 months. Overall and event-free survival (EFS) at 1 year were 54% (CI 48-60) and 50% (CI 43-57), respectively, the relapse incidence was 23% (CI 17-29). EFS was 67% (CI 55-79) in patients transplanted for acute leukaemias in first complete remission, chronic myelogenous leukaemia in first chronic phase, or severe aplastic anaemia. Transplantation of allogeneic PBPC resulted in prompt and durable engraftment. The incidence and severity of acute and chronic GVHD seemed comparable to that observed after allogeneic BMT. Overall and event-free survival in this cohort of patients, most of whom suffered from advanced leukaemia or lymphoma, is encouraging, suggesting that the high numbers of T lymphocytes and/or natural killer cells contained in a typical PBPC collection product exert a vigorous graft-versus-leukaemia effect. Further evaluation of allogeneic PBPCT is highly desirable.

RESUMO

Preemptive therapy is a promising strategy for the prevention of serious cytomegalovirus (CMV) disease after bone marrow (BM) transplantation but requires relevant diagnostic tests. We compared the clinical value of a reverse transcription (RT)-PCR method, which detected a late viral mRNA in peripheral blood leukocytes (PBL), with a PCR method that detected the viral DNA in PBL and with viral culture from leukocytes and urine for the diagnosis of symptomatic CMV infection after BM transplantation. Forty-five consecutive BM recipients were prospectively tested at weekly intervals by the four methods. CMV infection, demonstrated either by the culture of CMV or by repeated detection of viral DNA, was observed in 28 patients, but only 14 developed CMV-related clinical symptoms. The clinical sensitivity and specificity of each technique for detection of symptomatic infection were, respectively, 36 and 74% for urine culture, 43 and 84% for leukocyte culture, 100 and 65% for PCR, and 71 and 94% for RT-PCR. Although PCR detection of DNA in PBL was the earliest and most sensitive technique for the diagnosis of CMV infection, RT-PCR was more predictive of the onset of CMV-related clinical symptoms. These data suggest that both molecular methods should be used for identifying BM recipients at highest risk of CMV disease.

RESUMO

PURPOSE: Radiation-induced emesis is one of the most disturbing side effects of total body irradiation (TBI). To evaluate the efficacy and to determine the best schedule of granisetron (a selective 5-hydroxytryptamine3 serotonin receptor antagonist) administration in the prevention of radiation-induced nausea and vomiting, we conducted a trial involving patients receiving single-dose TBI before bone marrow transplantation (BMT). METHODS AND MATERIALS: Thirty-six patients with non-Hodgkin's lymphoma (n = 12), multiple myeloma (n = 8), acute lymphoblastic leukemia (n = 7), acute nonlymphoblastic leukemia (n = 6), and chronic myeloid leukemia (n = 3) referred to our department between March 1992 and February 1994 were enrolled in this study to assess the efficacy of granisetron during single-dose TBI before autologous BMT (n = 26), allogeneic BMT (n = 8), or syngeneic BMT (n = 2). The male-to-female ratio was 22:14 (1.57), and the mean age was 41 +/- 11 years (range 16-58). Before TBI, conditioning chemotherapy consisted of cyclophosphamide (CY) alone (60 mg/kg per day on 2 successive days) in 24 patients, CY combined with other drugs in 6, and combinations without CY in 6. All patients received single-dose TBI (10 Gy administered to the midplane at L4, and 8 Gy to the lungs). The mean instantaneous and average dose rates were 0.039 +/- 0.012 Gy/min (range 0.031-0.058), and 0.025-0.006 Gy/min (range 2.08-3.96), respectively. Granisetron was administered 30-45 min before TBI according to two different modalities: a total dose of 3 mg as a 5-min intravenous (i.v.) infusion (Treatment A, n = 15; 42%) or the same treatment plus 3 mg of granisetron as a 24-h continuous i.v. infusion (total dose: 6 mg, Treatment B, n = 21; 58%). Depending on the BMT teams, hyperdiuresis was continued (n = 19, 53%) or suspended (n = 17, 47%) during TBI. Nausea and vomiting were assessed during the TBI session and the following 12 h, and were scored as follows: S1 = no nausea or vomiting; S2 = moderate nausea; S3 = severe nausea and/or single episode of vomiting; and S4 = multiple episodes of vomiting. RESULTS: During TBI, 18 (50%) patients were scored as complete responders (S1), 1 (3%) as a major responder (S2), 9 (25%) as minor responders (S3), and 8 (22%) as nonresponders (S4). During the following 12 h, 28 (78%) patients were free of severe nausea and vomiting (S1 or S2), whereas 8 (22%) vomited (S3 or S4). In univariate analyses, the 12-h probability of emesis was significantly higher in patients undergoing hyperdiuresis (63% vs. 30%; p = 0.05), and in patients older than 45 years (65% for age > 45 vs. 33% for age < or = 45; p = 0.05). The probability of S3 or S4 emesis was 50% with Treatment A and 47% with Treatment B (p = 0.86). Sex, body weight, and type of conditioning chemotherapy did not influence the 12-h probability of emesis. Multivariate analysis revealed that hyperdiuresis (p = 0.02) and Treatment A (p = 0.04) were independently associated with radiation-induced emesis, whereas sex (p = 0.85), body weight (p = 0.13), age (p = 0.12), and type of conditioning chemotherapy (p = 0.92) were not. No early toxicity related to granisetron was observed. CONCLUSION: Granisetron is a well-tolerated and effective antiemetic agent that can be used as monotherapy during single-dose TBI. Good control of nausea and vomiting is obtained with this antiemetic drug, and its effect is increased when hyperdiuresis is suspended during TBI.

RESUMO

We report on seven adult leukemic patients who were autografted in spite of a prior history of invasive pulmonary aspergillosis (IPA). Their median age was 41 years (range: 19-61); six patients were male and one female. All seven had acute myeloblastic leukemia (AML) and underwent an autologous marrow transplantation (ABMT) with a marrow purged in vitro by mafosfamide. IPA was suspected prior to ABMT on clinical and radiological features. CT scan confirmed nodular infiltrates and cavitations in six cases. Microbiological documentation consisted of: identification of the fungus from bronchoalveolar lavage: one case, positive antigenemia: one case, positive antibodies: two cases. Prior ABMT patients received amphotericin B for a median total dose of 1915 mg (range: 970-3300). No patient underwent surgery. The median time from diagnosis of IPA to ABMT was 7.3 months (range: 3-10). During ABMT all patients received prophylactic amphotericin B and itraconazole. No patient died from toxicity and no IPA reactivation was observed in any patients. Post-graft, itraconazole was kept on for a median of 3 months (range: 3-5). This study demonstrates that IPA occurring during the management of AML patients is not necessarily a contraindication to subsequent ABMT.
