RESUMO

Chronic hepatitis C (CHC) patients often have altered quality of life. Few data are available about sexual impairment (SI) in CHC. From 2011 to 2013, we included consecutive CHC outpatients. Exclusion criteria were: antiviral therapy, co-infection, age <18 or >75, transplantation, alcohol consumption, Eastern Cooperative Oncology Group >1. Non-CHC subjects were healthy blood donors. Sexual questionnaires for men and women were adapted from the International Index of Erectile Function and Female Sexual Function Index, respectively, and concerned the past 30 days. Two hundred eighty-one patients were compared with 1086 blood donors. SI was more frequent in CHC patients. Men with CHC had worse desire, confidence, erections, climax and satisfaction (P<0.001). Women with CHC had worse desire, arousal, climax, satisfaction, lubrication and comfort (P<0.001). In multivariate analysis, factors associated with SI in men were CHC (odds ratio (OR)=4.45, 95% confidence interval (CI) 2.46-8.06), age (OR=1.06, 95% CI 1.03-1.09), no intercourse (OR=8.74, 95% CI 4.65-16.04) and unemployment (OR=2.14, 95% CI 1.16-3.95). Factors associated with a worse global sexual life in women were CHC (OR=7.96, 95% CI 4.07-15.58) and no intercourse (OR=21.39, 95% CI 11.03-41.48). The study results were corroborated by propensity score-matching analysis. Sexual life is impaired in men and women with CHC. In clinical practice, sexual quality of life should be evaluated and treated.

RESUMO

PURPOSE: A small proportion of patients with chronic myeloid leukemia (CML) achieve a complete cytogenetic response (CCR), defined as the disappearance of Philadelphia (Ph) chromosome-positive metaphases, after treatment with interferon alfa (IFN). In this population of patients, the question of whether treatment should then be withdrawn is not yet resolved. PATIENTS AND METHODS: In the present study, we followed 15 patients who stopped IFN after achieving CCR. In nine patients IFN was stopped in view of adverse reactions (n = 8) or patient's choice (n = 1). For the remaining six patients, the treatment was stopped because no BCR/ABL rearrangement could be detected by reverse transcriptase polymerase chain reaction (RT-PCR) in four successive analyses using peripheral-blood samples. RESULTS: Loss of CCR and survival were not statistically different (P =.48; P =.7) for the 15 patients who stopped IFN compared with 41 other CCR patients who continued IFN therapy in our institution. The median follow-up after discontinuation of IFN treatment was 36 months (range, 6 to 108 months). Seven patients (47%) (females, or CCR > 24 months and RT-PCR negative before IFN cessation; P <.0001) did not relapse. Eight other patients (53%) relapsed (lost CCR) within 3 to 33 months of treatment discontinuation. One of them relapsed in major cytogenetic remission (MCR) and was still in MCR 87 months after stopping therapy without any treatment. CONCLUSION: It is possible to stop IFN treatment at least in some patients with CML who achieve a prolonged period of CCR. This study also illustrates the hypothesis that persistence of low numbers of Ph-positive cells does not necessarily imply hematologic relapse.

RESUMO

PURPOSE: The aims of the current study were to evaluate in patients with high-risk multiple myeloma (MM) the feasibility and usefulness of high-dose chemotherapy or chemoradiotherapy followed by hematopoietic stem-cell support with autologous peripheral-blood progenitor cells (PBPC) harvested after high-dose cyclophosphamide (HDCYC). PATIENTS AND METHODS: Seventy-three patients with high-risk MM were entered onto the study. Before the procedure, all patients had received HDCYC to collect PBPC by leukapheresis. One patient died of infection after HDCYC. All other patients subsequently received high-dose melphalan (HDM) (140 mg/m2) either alone (n = 1) or associated with either busulfan (16 mg/kg; n = 4) or total-body irradiation (TBI) (8 to 15 Gy; n= 67). In addition, three of the latter patients received cyclophosphamide (120 mg/kg). Thereafter, PBPC were reinfused either alone in 61 patients or together with back-up bone marrow cells in 11 patients in whom the granulocyte-macrophage colony-forming unit (CFU-GM) cell content of the leukapheresis was low. RESULTS: One patient died of acute cardiac failure after reinfusion of PBPC; three patients did not respond after autologous blood progenitor cell transplantation (ABPCT), while the other 68 patients achieved either a complete response (CR; n = 32) or partial response (PR; n = 36). Thirty-six patients relapsed or progressed after a median response duration of 14.5 months (range, 3 to 43) and 19 of these subsequently died. Four other patients died while still responsive of lung cancer (n = 1) or infection (n = 3). The remaining 28 patients are currently alive and still responding with a median follow-up duration of 27 months (range, 6 to 66). The 3-year probability of survival was 66% +/- 12% (95% confidence interval [CI] after ABPCT and 77% +/- 51% (95% CI) from diagnosis. CONCLUSION: High-dose chemotherapy or chemoradiotherapy followed by autologous PBPC support in MM is feasible and efficient. Further studies are needed to confirm these encouraging, although preliminary, results and to compare this technique with other therapeutic strategies.

RESUMO

To improve the management of chronic myeloid leukemia (CML) in a single center, we used interferon alpha (IFN alpha) to treat newly diagnosed CML patients and investigated the factors predictive of a major cytogenetic response. Fifty-two patients (pts) with a median age of 51.5 years (16-68), were given interferon alpha (IFN alpha) (5 millions/m2/day, subcutaneously). The median interval between diagnosis and IFN alpha was 41.5 days (0-160). The doses of INF alpha were adjusted to maintain the white blood cell (WBC) count between 1.5 and 5 x 10(9)/l and the platelet count between 50 and 100 x 10(9)/l. At diagnosis, Sokal's criteria were used to classify patients into three groups: low (n = 24), intermediate (n = 19) and high risk (n = 9). A complete hematological response (CHR) was achieved in 42 cases (80.7%). A partial response was present in nine; only one patient did not respond. By multivariate logistic regression analysis, only the age at diagnosis was found to influence the CHR rate (P = 0.06). Cytogenetic response was evaluated in 46 responder patients. Twenty-three patients achieved a major cytogenetic response (MCR) which was either partial ( > or = 65% pH negative cells) (n = 3) or complete (CCR) (n = 20). By univariate analysis, two disease-related variables were found to influence the MCR rate in 40 evaluable CHR patients: spleen size at diagnosis and peripheral blood blast percentage. However, using either univariate or multivariate analysis, the most significant factor was the achievement of CHR within 3 months (P < 0.0004 and P < 0.0002, respectively). These results show that IFN alpha can induce high rates of hematological and cytogenetic responses when administered in doses leading to myelosuppression. The achievement of CHR within 3 months could be useful to identify early, those patients who will not respond to IFN alpha and who need alternative treatments such as allogeneic or autologous stem cell transplantation.

RESUMO

Autografting could become a promising treatment for patients with chronic myeloid leukemia (CML) who cannot undergo allogeneic bone marrow transplantation or failed to respond to recombinant alpha-interferon (IFN). In this review, we analyze the results which have been published for patients transplanted in chronic phase and which suggest that autografting could prolong survival, at least in some patients. We also discuss the different methods of purging whose clinical efficacy remains to be assessed.

RESUMO

The aim of the study was to analyze the factors influencing peripheral blood progenitor cell (PBPC) collection after high-dose cyclophosphamide (HDCYC) (7 g/m2) and hematopoietic recovery after autologous transplantation of HDCYC-mobilized PBPC (ABPCT) in 116 patients with aggressive multiple myeloma (MM). Following HDCYC 74 patients received hematopoietic growth factors (HGF), either G-CSF (n = 19) or GM-CSF (n = 55). All the patients were subsequently planned to undergo ABPCT. PBPC collection was possible for 106 patients. The most important prognostic factor for collection of more than 25 x 10(4) CFU-GM cells/kg and 2 x 10(6) CD34+ cells/kg was the use of HGF (P = 0.002 and 0.009, respectively). Previous use of an alkylating agent, response to treatment before HDCYC, and interval between diagnosis and HDCYC were also significant factors (P = 0.004, 0.025 and 0.001, respectively). The number of CFU-GM cells infused was the most important parameter for rapid and complete hematological recovery after ABPCT (P < 0.0001). Thus the use of HGF post-HDCYC is the major factor which, associated with reduced time between diagnosis and HDCYC and the use of an alkylating agent, could increase the numbers of hematopoietic progenitors collected, and subsequently improve hematopoietic recovery following ABPCT in MM patients.

RESUMO

In 204 adult patients with de novo acute myeloid leukemia (AML), we prospectively compared allogeneic bone marrow transplantation (alloBMT), autologous stem cell transplantation (ASCT) and chemotherapy (Chemo). 162 patients (79.4%) achieved a complete remission (CR). Of the 135 patients who were still in CR after consolidation, 96 patients were less than 46 years of age: 36 patients had an HLA-identical sibling donor and were allocated for alloBMT (group I); they were compared to the 60 other patients who did not have an HLA-identical sibling donor and were treated with either ASCT or chemotherapy (group II). The 3-year disease-free survival was higher for group I patients (66.5 +/- 16%) than for the 60 group II patients (42.4 +/- 13%) (P < 0.05). The actuarial risk of relapse at 3 years was significantly lower for group I patients (24 +/- 15%) than for the other 60 group II patients (56 +/- 13%; P < 0.009). By multivariate analysis, the disease-free survival and risk of relapse were influenced by the initial WBC count (P < 0.02 and P < 0.006), the number of chemotherapy courses for CR (P < 0.001 and P < 0.01) and the type of post-induction treatment (alloBMT vs no alloBMT; P < 0.1 and P < 0.02). The 99 patients who did not fulfill the inclusion criteria for alloBMT were given intensive chemotherapy including high-dose aracytine. When they were still in CR (n = 77), these patients were then randomized for either ASCT (n = 39) or Chemo (n = 38). We were unable to detect any statistical difference between ASCT and Chemo for either disease-free survival, risk of relapse or survival. These results indicate that alloBMT seems to produce results which are at least superior to those of other therapeutic modalities. The results of either ASCT or Chemo look similar.

RESUMO

A prospective randomized study was conducted comparing the efficacy and toxicity of two anthracyclines for the treatment of patients with acute myeloid leukemia (AML) between 55 and 75 years. A total of 220 patients were randomized to receive as induction chemotherapy cytosine arabinoside (Ara-C: 100 mg/m2/day; continuous infusion for 7 days) combined with either daunorubicin (DNR: 50 mg/m2/day, i.v. bolus for 3 days) (n=108) or idarubicin (IDA: 8 mg/m2/day, i.v. bolus for 5 days) (n=112). The complete remission (CR) rate was similar (P=0.296) after IDA (76/112; 68%) and DNR (66/108; 61%) (P=0.3). For patients aged 55-65, the CR rate was significantly higher after IDA (39/47; 83%) than after DNR (29/50; 58%) (P=0.007). Persistent leukemia was more frequent after DNR (26/108) than after IDA (13/112; P=0.015). Hematological and extra-hematological toxicities were similar. The CR patients were given a consolidation course of chemotherapy with Ara-C: 50 mg/m2/12 h, subcutaneously for 5 days, combined with either DNR:30 mg m2/day, i.v. bolus for 3 days or IDA:8 mg/m2/day i.v. bolus for 3 days according to the initial randomization, and then received a continuous maintenance treatment for 2 years. The survival and disease-free survival (DFS) were similar in both groups; there was no difference in the risk of relapse. However, there was a trend for a longer event-free survival (EFS) in the IDA group than for the DNR patients (P=0.07). Our results seem to indicate that IDA is probably more efficient than DNR for AML patients between 55 and 75 years, and confirm the data published in other studies comparing prospectively IDA and DNR in adults.

RESUMO

Autologous stem cell transplantation (ASCT) was performed in 95 patients with chronic myelogenous leukemia (CML) in chronic phase and their data were reported to the European Bone Marrow Transplant Registry. Most patients presented bad prognostic factors. The results were analysed by September 1, 1993. The actuarial proportion of patients who achieved a complete hematological response at one year was 87.3+/-7.5% (95% CI). The 3-year percentage of major cytogenetic response was 38.6+/--13% (95% CI). The actuarial risk of transformation for the evaluable patients was 31.5+/-14% (95% CI) and the actuarial survival at four years was 83.3+/-10% (95% CI). These encouraging results suggest that ASCT by itself could play a role to prolong survival in CML patients.

RESUMO

In our institution, total body irradiation (TBI) is performed by means of a sweeping beam technique. Toxicity of the procedure was evaluated according to the only grading system designed for high dose chemoradiotherapy. One hundred patients undergoing TBI and conditioned with a standard cyclophosphamide regimen before BMT were evaluated. Regimen-related toxicity was graded according to the Seattle transplantation toxicity system, from 0 to IV (fatal toxicity), in eight organs on days 0, 7, 14, 28 and 100 for lungs. Eighteen patients did not develop any toxicity. Grades III, IV toxicities were uncommon (9%) and were not influenced by dose of TBI, GVHD prophylaxis, disease status and allogenicity although no grade IV toxicity was observed among autologous marrow recipients. However, grade II toxicity was more common in patients receiving allogeneic vs autologous grafts (p < 0.01) because of increased mucosal (p = 0.002) and liver (p = 0.12) toxicities. Renal toxicity was unevaluable. When cumulative toxicity was equal or higher than 4, day 100 survival was worse (p = 0.05). These data confirm the safety of our TBI procedure and the validity of the grading system except for renal toxicity. We suggest that a more aggressive conditioning regimen may be tolerated by patients receiving autologous grafts.

RESUMO

High-dose cyclophosphamide (HD-CY; 7 g/m2) was administered to patients suffering from high risk multiple myeloma (MM). The safety of this procedure, the recirculation and collection of peripheral blood stem cells (PBSC) and the effect of rhGM-CSF and HD-CY were studied. Group I patients (n = 21) were treated with HD-CY alone. Group II patients (n = 10) received 5 micrograms/kg/day rhGM-CSF iv after HD-CY. Neutropenia was shorter in group II (p = 0.01). In group II, the number of circulating colony forming units (CFU-GM) after 14 days was correlated with the number of circulating CFU-GM after 7 days (r = 0.85, p < 0.0001) and with the number of CD34+ cells (r = 0.839, p = 0.01). The total number of mononuclear cells (MNC) and CFU-GM collected per patient was two and seven-fold higher, respectively, in group II (p = 0.01 and p = 0.03). Recovered MNC and CFU-GM were 1.7 and 7-fold higher, respectively, in group II (p = 0.01 and p = 0.004). Our data show that HD-CY is an efficient means of collecting functional PBSC in MM. We suggest that rhGM-CSF is able to further enhance this yield in MM.

RESUMO

To improve the management of chronic myeloid leukemia (CML) in a single center, we have used interferon-alpha (IFN-alpha) to treat newly diagnosed Ph-positive CML patients and investigated the factors predictive of a major cytogenetic response. Eighty-one patients with a median age of 50.5 y (17-70) were given IFN-alpha (5 x 10(6)/sqm/day, s.c.). The median interval between diagnosis and IFN-alpha was 45 days (0-160). IFN-alpha doses were adjusted to maintain the white blood cell (WBC) count between 1.5 and 5 x 10(9)/l and the platelet count between 50 and 100 x 10(9)/l. At diagnosis, Sokal's criteria were used to classify patients into three groups: low (n = 39), intermediate (n = 32) and high risk (n = 10). A complete hematological response (CHR) was achieved in 66 cases (81.5%). Cytogenetic response was evaluated in these 66 responders. Thirty-six patients (44.4%) achieved a major cytogenetic response (MCR) (> or = 65% Ph-negative cells), 31 of them having a complete cytogenetic response. The 5-y transformation-free survival (TFS) of the 81 patients was 77 +/- 14% (95% CI) and was statistically influenced by the CHR rate at three months (p = 0.008) and the achievement of MCR or CCR (p < 0.0009 and p < 0.0005, respectively). Moreover, we found that the MCR or CCR were significantly influenced by the obtaining of CHR at three months (p < 0.001 and p < 0.0001, respectively). These results show that IFN-alpha can induce high rates of hematological and cytogenetic responses when administered in doses leading to myelosuppression. The achievement of CHR within three months could be useful to identify early those patients who will not respond to IFN-alpha and who need alternative treatments such as allogeneic or autologous stem cell transplantation.

RESUMO

Between 1980 and 1996, we transplanted 72 patients with CML using blood stem cells collected at diagnosis before treatment and without any mobilization. The median age of patients at diagnosis was 47.5 years (range 20.5-59.5). The median numbers of nucleated cells and CFU-GM transplanted were 10 x 10(8)/kg and 97 x 10(4)/kg, respectively. The median duration to reach more than 0.5 x 10(9)/l neutrophils and 50 x 10(9)/l platelets was 12 (range 5-19) and 11 days (range 0-79), respectively. Twenty patients (group I) were transplanted in chronic phase either for resistance to IFN (14 patients) (group IA) or because the Sokal index was more than 1.2 (six patients) (group IB). All those patients had preparative regimen with busulfan (4 mg/kg/day x 4) and melphalan (140 mg/m2). They were treated with recombinant alpha-interferon (IFN) after transplant. The cumulative incidence of major cytogenetic response (MCR) at 12 months was 25 +/- 21% (95% CI), the 5-year survival was 75 +/- 42% (95% CI). These results (observed in patients with bad prognosis factors) are similar to those usually observed in CML patients treated by IFN, whatever the Sokal risk. Thus autologous transplantation is able to reproduce for poor prognosis patients the results observed in standard risk patients treated with IFN. This suggests that it could prolong survival. Fifty-two other patients (group II) were transplanted for CML in transformation (accelerated phase = 32; blast crisis = 20) after a preparative regimen containing either total body irradiation (TBI) or busulfan. The median survival was short (10.4 months) and only 21 patients survived more than 1 year. The survival was longer for patients transplanted in accelerated phase (vs blast crisis), those who were due to receive a double transplant (vs single) (34 patients), those who were treated with IFN after transplant (vs hydroxyurea) and for the patients who obtained a complete hematologic response.

RESUMO

We retrospectively analysed the factors that influenced rate of haemopoietic recovery (HR) in 243 patients after transplantation with chemotherapy-mobilised autologous peripheral blood progenitor cells (PBPC). Approximately half the patients also received haemopoietic growth factors (HGF) for mobilisation. Conditioning for transplantation was with either chemotherapy alone or chemotherapy plus total body irradiation (TBI). Median time to recovery of granulocytes > or = 0.5 x 10(9)/l was 13 days (range 7-93 days) and of platelets > or = 50 x 10(9)/l 14 days (7-440). Speed of HR was greater, both for neutrophils and platelets for patients who received more rather than less CFU-GM than our median value of 18.9 x 10(4)/kg (P < 0.0001 in both instances) and more rather than less CD34-positive cells than our median value of 8.8 x 10(6)/kg (P < 0.0001 and P < 0.0005, respectively). For granulocyte recovery, in the multivariate analysis the dose of infused CFU-GM (P = 0.05) and the use of HGF for both mobilisation and post-transplantation (P < 0.0014) were significant positive factors. For platelet recovery in the multivariate analysis the dose of infused CFU-GM (P < 0.0016) was a positive factor. The use of busulphan and of TBI were significant adverse factors for rate of platelet recovery (P = 0.005 and 0.0004, respectively). When compared with non-HGF-mobilised PBPC, HGF-mobilised PBPC reduced the number of days of hospitalisation (28 vs 24, P = 0.0001) and of treatment with intravenous antibiotics (15 vs 11, P = 0.0004). These findings emphasise the importance of cell dose in accelerating haemopoietic recovery after autologous blood stem cell transplantation.

RESUMO

Autologous blood stem cell transplantation (ASCT) was performed in 32 patients with high risk chronic myelogenous leukemia (CML). Prior to ASCT, the patients were given Busulfan and high-dose Melphalan. Peripheral blood stem cells collected at diagnosis were used to rescue hematopoiesis. Recombinant Interferon was administered after ASCT. In 24 patients transplanted in transformation, 23 achieved a complete hematological response and nine are still alive 9 to 73 months after ASCT. Eight other patients were transplanted in chronic phase for either the presence of bad prognostic factors (Sokal's classification) or no response to IFN. Seven are alive without transformation 16 to 48 months after ASCT. Although few patients presented a cytogenetical response (10/28), the survival observed in this series of patients compares favorably with that of patients treated conventionally. Thus, the place of ASCT in CML could now be tested prospectively.

RESUMO

The DNR accumulation (DNR Acc) and the verapamil (VRP) index (percent increase of VRP on DNR accumulation) was studied by using flow cytometry. Fresh leukemic mononuclear bone marrow blasts from 80 unselected ANLL patients' samples were incubated with DNR in the presence or absence of VRP. The DNR accumulation was determined by flow cytometry. The median DNR Acc was 28 (range: 4-101) and the median VRP index was 4% (range 0-53). VRP significantly enhanced DNR Acc in 42 of the ANLL samples (52.5%). DNR Acc or VRP index were not influenced by age, sex, or WBC counts. Only the FAB subclassification and the blast immunophenotyping were found to influence the parameters studied here. The lowest DNR Acc was found in M0 and M6 blast cells (15 range 0-46 and 10.5 range 8-13 respectively). M4 and M5 ANLL samples accumulated significantly more DNR than M0 and M6 blast cells. The VRP index was significantly higher in M0 compared with M1 and M2 samples, as well as in M4 compared with M1 samples. A slightly positive correlation was found between the percentage of CD34-positive cells in the CD34-positive samples and DNR Acc. In this study, DNR Acc and the VRP index were not significantly correlated with the response to chemotherapy or survival. In conclusion, this study shows that ANLL leukemic cells differ in anthracyclin accumulation and response to VRP in vitro.

RESUMO

Allogeneic transplantation is a well recognized treatment strategy of leukemia. However, its use in advanced leukemia patients is a subject of some debate especially when donors are not HLA-identical siblings because of the toxicity and cost of the procedure. We reviewed retrospectively the outcome of patients (pts) who received allogeneic transplantation for advanced acute leukemia in our center between 09/86 and 11/97. Thirty-six pts (study group) who lacked a matched sibling donor received partially matched related donor (n=14: PMRD group) or matched unrelated donor transplantation (n=22: MUD group). Fifteen pts had AML and 21 ALL. Seventeen pts (47%) were in CR>1, 13 pts (36%) had refractory disease and six pts (17.7%) were in untreated relapse. The outcome was compared to that of 56 patients (AML: 45.5 %, ALL: 55.5 %, CR>1: 49.9 %, refractory disease: 37.5 %, untreated relapse 19.6 %) who received allogeneic transplantation from a matched sibling donor (control group). Various conditioning regimens and GVHD prophylaxis were used. The actuarial incidence of grade II to IV acute GVHD was significantly higher in the study group (57%) than in the control group (34%) (p=0.047). The actuarial risk of relapse at three years was 21% +/- 22% in the study group versus 65% +/- 16% in the control group (p= 0.04). The actuarial probability of transplant-related mortality at 3 years is 64 +/- 16% for the study group and 25 +/- 11% for the control group (p=0.001). The leading cause of death in the study group was infection (30%) followed by acute GVHD and relapse. Relapse was the major cause of death in the control group (54%), followed by infection, interstitial pneumonia, veno-occlusive disease and GVHD. The OS and probability of leukemia-free survival at 3 years were 28 % +/- 15% (95% CI) and 27% +/- 15% (95% CI) in the study group. The overall survival and probability of LFS at 3 years were respectively 28 +/- 12% (95% CI) and 23 +/- 12% (95% CI) in the control group (p = 0.08 and p=0.11 respectively). In multivariate analysis, transplant-related mortality was higher in the study group (p=0.04) and lower if both donor and recipient were seronegative for CMV (p=0.007). OS was significantly higher for seronegative couples (p=0.0001), and when CR was achieved before BMT (p=0.0022). These results suggest that all efforts in this field should be directed on lowering the transplant related mortality for non geno-identical transplants and the relapse rate in geno-identical transplants.

RESUMO

Between 50 and 75% of adult patients with de novo acute myeloid leukemia achieve complete remission (CR) but 25 to 40% of them require more than one course of induction chemotherapy to achieve CR. In order to investigate the impact of this situation on the overall outcome of patients we conducted a retrospective analysis of 130 patients, resistant to a single induction course from among three consecutive protocols, using the same induction regimen employed by the BGMT study group. This group of patients has a particularly poor prognosis with relapse and survival rates of 70% and 14% respectively at 5 years. For these patients, being in CR after two induction courses appears to be a major prognostic factor for outcome, since the 5-year Kaplan-Meier survival probability is significantly better (29%, range 17-46) than of those patients with resistant disease (5%, range 2-13). However, results are worse than when complete remission is obtained after a single course. Thus, post remission treatment should have a powerful anti-leukemic effect in preventing relapse. Allogeneic bone marrow transplantation is a preferential strategy in this setting but to be effective this should be performed as early as possible. Furthermore, these results indicate that allogeneic bone marrow transplantation from an alternative donor should be considered in the absence of HLA identical sibling.

RESUMO

Autologous stem cell transplantation has increased in France over the last five years, mainly due to a marked increase in the number of autologous peripheral blood progenitor cell (PBPC) transplants, which represented about 66% of autologous transplants performed in 1994. This increase is related to the more rapid engraftment observed after PBPC transplantation than after bone marrow transplantation (BMT). The rate of haematopoietic recovery is significantly influenced by the dose of CFU-GM infused, by use of haematopoietic growth factors for mobilization and to a lesser extent after transplantation and by types of conditioning regimens. However, the outcome of patients does not seem to differ following PBPC as compared to bone marrow transplantation.
