Big BU/CY is associated with a favorable long-term outcome in patients allotransplanted for chronic myelogenous leukemia in chronic phase.

Twenty-six adult patients, median age 36 years (range 21-53) with chronic myeloid leukemia in first chronic phase were allotransplanted between October 1989 and May 1995. The preparative regimen consisted of busulphan 16 mg/kg and cyclophosphamide 200 mg/kg (big BU/CY). Cyclosporin A and methotrexate were used for GVHD prophylaxis. Twenty-two donors were HLA-identical siblings and four donors were mismatched for one antigen of class I. The global incidence of acute GVHD was 50%, that of severe aGVHD (grades 3-4) was 11%; the global incidence of chronic GVHD was 30%. No patients developed veno-occlusive disease of the liver or interstitial pneumonia. Five patients died, one of relapse, four of transplant-related causes, mostly related to aGVHD; thus, the transplant-related mortality was 16%. Twenty-one patients are alive, in remission, with a median follow-up of 55 months (range 24-90); actuarial probability of survival is 78% (CI 64-96). Our study shows that this conditioning regimen is relatively easy to administer and seems to be as effective as, if not superior to, regimens containing TBI, in patients with chronic myeloid leukemia in chronic phase and the transplant-related mortality is not excessive even in older patients.

High-dose busulfan and cyclophosphamide are an effective conditioning regimen for allogeneic bone marrow transplantation in chemosensitive multiple myeloma.

The present clinical trial was undertaken to investigate the toxicity and antimyeloma activity of busulfan (BU) and cyclophosphamide (CY) at the maximum tolerated doses of, respectively, 16 mg/kg and 200 mg/kg (BU-CY 4) as conditioning therapy for allogeneic bone marrow transplantation (BMT) in 19 consecutive patients with multiple myeloma (MM). Twelve (63%) had failed to respond to prior chemotherapy, while the remaining 37% had chemosensitive disease. No life-threatening or fatal regimen-related complications were observed. The incidence of veno-occlusive disease of the liver was zero according to Jones' criteria and 21% according to McDonald's system. Transplant-related mortality was 37%. Using stringent criteria, the frequency of complete remission (CR) was 42% among all patients and 53% among those who could be evaluated. With a median follow-up of 21 months for all patients and 66 months for survivors, the actuarial probability of survival and event-free survival at 4 years from BMT was 26% (95% CI: 7-46) and 21% (95% CI: 3-39), respectively. A more favorable outcome of transplantation was observed in the subgroup of patients with chemosensitive disease who had a transplant-related mortality of 14%, an overall CR rate of 86% (95% CI: 49-97) and a 4-year projected probability of event-free survival of 57% (95% CI: 20-93). Four of these patients are currently alive in continuous CR after 54, 66, 80 and 94 months, respectively. It is concluded that BU-CY 4 as conditioning for allogeneic transplantation for MM is associated with acceptable morbidity and relatively low mortality. This regimen exerts substantial antimyeloma activity, resulting in a high CR rate and durable responses, especially in patients with chemosensitive disease. Long-lasting remission and probable cure is possible following allogeneic stem cell transplantation for MM.

Unrelated donor marrow transplantation for chronic myelogenous leukaemia.

Between January 1989 and July 1995 the search for an unrelated donor (UD) was started for 379 consecutive Italian patients with Philadelphia positive (Ph+) chronic myelogenous leukaemia (CML). 89 (23%) were transplanted. The overall probability of transplant before and after December 1991 was 16% and 49%, respectively (P=0.0001), and average interval between search activation and graft was 23 months and 13 months, respectively (P=0.0001). Disease-free survival (DFS) following 60 consecutive transplants performed before February 1996 was 41.5% at 48 months and was 64% for patients grafted after January 1993. In univariate analysis, five variables had a favourable effect on DFS: year of bone marrow transplantation (BMT) after 1993 (P=0.0002), HLA-DRB1 donor/recipient (D/R) match (P=0.0006), total body irradiation (TBI) containing regimen (P=0.0006), graft-versus-host disease (GvHD) prophylaxis including 'early' cyclosporin before the transplant, and a marrow cell dose > 3 x 10(8)/kg of recipient body weight (P=0.04). Multivariate analysis confirmed that HLA identity (P=0.006), TBI-containing regimen (P=0.0001) and 'early cyclosporin' (P=0.04) were associated with higher DFS. Transplant-related mortality (TRM) was 67% in patients grafted before January 1993 and 30% in patients grafted subsequently (P=0.002). Multivariate analysis confirmed DRB1 identity (P=0.03) and TBI-containing regimen (P=0.0005) to be independent factors predictive of low TRM. This suggests that the outcome of patients transplanted from an HLA DRB1 matched donor, after a TBI-containing preparative regimen, is similar to results recently reported in patients transplanted from geno-identical siblings. These results indicate that the search should be initiated at diagnosis for patients < 45 years of age and UD BMT should be considered early in the disease course for those with an available DRB1-matched unrelated donor.

CHOP is the standard regimen in patients > or = 70 years of age with intermediate-grade and high-grade non-Hodgkin's lymphoma: results of a randomized study of the European Organization for Research and Treatment of Cancer Lymphoma Cooperative Study Group.

PURPOSE: We report the results of a randomized study of the European Organization for Research and Treatment of Cancer (EORTC) Lymphoma Group, which compared a chemotherapy regimen specifically devised for elderly patients, ie, etoposide, mitoxantrone, and prednimustine (VMP), versus the standard regimen of cyclophosphamide, doxorobucin, vincristine, and prednisone (CHOP) in patients older than 70 years of age with intermediate- and high-grade non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Patients older than 70 years of age with stage II, III, or IV intermediate- and high-grade NHL, with an Eastern Cooperative Oncology Group (ECOG) performance status less than 4 and acceptable cardiac, renal, and liver function were randomized to receive six courses of VMP or six courses of CHOP. Between February 1989 and June 1994, 130 patients aged 70 to 93 years (median, 75) were enrolled and 120 were assessable for response, 60 patients in each arm. RESULTS: Overall objective response rates were 50% and 77% in VMP- and CHOP-treated patients, respectively (P = .01), while complete response (CR) rates were borderline significant (27% v 45%; P = .06). At 2 years, the progression-free survival (PFS) rate was 25% with VMP versus 55% with CHOP (P = .002) and the overall survival (OS) rate was 30% with VMP versus 65% with CHOP (P = .004). Statistically significant more alopecia and neurologic and gastrointestinal toxicities were reported with CHOP. CONCLUSION: CHOP is the standard regimen for patients > or = 70 years of age with stage II to IV intermediate- and high-grade NHL.

Allogeneic peripheral blood stem cell transplantation in patients with early-phase hematologic malignancy: a retrospective comparison of short-term outcome with bone marrow transplantation.

BACKGROUND AND OBJECTIVE: Transplantation of mobilized allogeneic peripheral blood stem cells (PBSC) has recently been reported by several groups. However, few patients receiving an allograft in the early stage of their disease have been described so far. DESIGN AND METHODS: Fifteen patients with early stage hematologic malignancies were transplanted with cryopreserved allogeneic PBSC from HLA-identical siblings. PBSC were collected after priming with 10 micrograms/kg/day of glycosylated granulocyte colony-stimulating factor (G-CSF, lenograstim). Outcomes were compared to a historical control group of 15 patients who received conventional bone marrow transplantation (BMT) from HLA-identical sibling donors. The two groups were matched for diagnosis, stage of disease, age, preparative regimen, graft-versus host (GVHD) prophylaxis, patients' and donors' gender and cytomegalovirus (CMV) serology. Diagnoses in both groups were: chronic myelogenous leukemia (CML) in first chronic phase (= 5), acute leukemia in first complete remission (CR) (= 5), non-Hodgkin's lymphoma in CR (= 1) and multiple myeloma (MM) with sensitive disease (= 4). All patients were given cyclosporin-A (CsA) and methotrexate (MTX) for GVHD prophylaxis. Preparative regimens varied according to diagnosis and included either busulfan/cyclophosphamide combination (BU/Cy) or total body irradiation/cyclophosphamide +/- melphalan (TBI/Cy +/- Mel). RESULTS: The patients in the PBSC group showed a more rapid hematopoietic reconstitution with a significant difference in the median times to 1 x 10(9) neutrophils/L (19 days vs. 26 days; p = 0.03) and to platelet transfusion independence (18 days versus 22 days; p = 0.02). This finding was associated with a significantly shorter hospitalization (28 days versus 33 days after transplantation; p = 0.01). In the PBSC series, grade II-IV acute GVHD occurred in 3 patients (20%) and grade III-IV in 1 patient (7%). In the BMT control group, grade II-IV aGVHD was reported in 2 cases (13%; p = NS) and 1 case had grade III-IV GVHD. Chronic GVHD developed in 7 patients (47%) (limited = 6; extensive = 1) undergoing PBSC transplantation and 5 patients (33%) (limited = 4; extensive = 1) in the BMT series (p = NS). No difference was found in the incidence of grade II-IV (according to the World Health Organization) mucositis, whereas PBSC recipients did have a significantly lower incidence of additional severe (grade III-IV) organ toxicity. After a median follow-up of 300 days (range 180-630), all PBSC patients are still alive with a median Karnofsky score of 100% (range 80%-100%). Thirteen patients are in CR and 2 myeloma patient are in good partial remission (PR). Also, in the BMT group the peritransplant mortality was absent; two MM patients died due to progressive disease at day +796 and +1,023, respectively; one leukemic patient died of chronic GVHD 407 days after transplantation and one additional leukemic individual relapsed 1,140 days after BMT. INTERPRETATION AND CONCLUSIONS: This retrospective comparison suggests that allogeneic PBSC transplantation performed in the early stage of the disease is safe and may be associated with a more rapid hematopoietic reconstitution than BMT, as well as lower transplant-related toxicity and earlier hospital discharge with apparently no increased risk of acute and chronic GVHD.

Prior treatment with alpha-interferon does not adversely affect the outcome of allogeneic BMT in chronic phase chronic myeloid leukemia.

BACKGROUND AND OBJECTIVE: Controlled clinical trials have shown that Interferon-alpha (IFN-alpha) is able to control myeloid proliferation and to suppress the Ph+ clonal hemopoiesis in early chronic phase chronic myeloid leukemia (CML): a growing number of patients are treated with this agent from diagnosis. However, if a CML patient has an HLA-identical sibling, bone marrow transplant (BMT) represents the best choice of treatment. Since IFN-alpha is known to modify the immunologic response and to increase marrow fibrosis, information is needed on the outcome of patients transplanted after IFN-alpha treatment. DESIGN AND METHODS: We analyzed retrospectively 32 Ph+ CML patients submitted to BMT in the last 6 years in Institute "Serágnoli". All the patients were in 1st chronic phase, their median age was 37 years, the donors were HLA-identical (27/32) or 1 Ag-mismatched (5/32) siblings. Big BuCy was the conditioning regimen employed for all and GVHD prophylaxis was based on CsA in 4 patients and Csa+MTX in 28 patients; all patients received homogeneous pre and post-transplant supportive care, antimicrobial and antiviral prophylaxis. These patients were divided into 2 groups according to the treatment before BMT: 16 received IFN from diagnosis to BMT (mean dose 6.9 MU/daily) for at least 6 mos (mean 23 mos, range 8-75) and 16 received chemotherapy alone (hydroxyurea [HU]). RESULTS: Hematological recovery was comparable in the two groups: time to 0.5 x 10(9)/L PMN was 20.5 days (range 11-32) in the IFN group and 20 days (range 10-32) in the HU group; time to 50 x 10(9)/L platelets was 28 days (range 20-117) in the IFN group and 27 days (range 20-112) in the HU group. The incidence of acute GVHD was not different in the two groups for any grade of the disease; in patients who survived more than 100 days, chronic GVHD occurred in the two groups with the same frequency. Seven patients died of transplant related mortality (TRM), 4 in the IFN group and 3 in the HU group. Hematological relapse was observed in only one case in the HU group; no cytogenetic relapse occurred. Disease free survivals at 7 years are 61% and 72%, respectively; the difference is not significant. INTERPRETATIONS AND CONCLUSIONS: Notwithstanding the low number of patients included in this study, the data reported here confirm that prior treatment with alpha-IFN does not adversely affect transplant outcome.

Detection of bcr-abl transcript in chronic myelogenous leukemia patients by reverse-transcription-polymerase chain reaction and capillary electrophoresis.

BACKGROUND AND OBJECTIVE: Capillary electrophoresis (CE) has become an attractive alternative to SLAB gel analysis for direct and accurate detection of amplified product, and a few cycles of polymerase chain reactions (PCRs) could be sufficient for both quantitative and qualitative analysis. We try to assess: 1) whether CE could be a practical, non-isotopic method for direct detection of the presence of amplified bcr-abl obtained by a reverse transcription (RT)-PCR (qualitative analysis) and 2) whether it is possible to quantify PCR products using a competitive RT-PCR measuring peak areas of CE electropherograms (quantitative analysis). DESIGN AND METHODS: The two types of bcr-abl chronic myelogenous leukemia (CML) associated transcript products were generated by RT-PCR (qualitative analysis) from 1 microgram of total RNA extracted from bone marrow samples of 34 CML patients at diagnosis (median age 47.5; range 18-65; median Sokal's score 0.9; range 0.53-2.78). The PCR products were analyzed by SLAB-gel electrophoresis (SGE) on 2% agarose gels and by CE (128 runs; median 3.3 times for each sample). Furthermore, we assessed the amount of PCR product (quantitative analysis) by a competitive RT-PCR approach and by CE (bcr-abl transcripts were expressed as transcript per microgram of total RNA examined). RESULTS: CE separation of PCR products obtained by qualitative RT-PCR showed baseline resolution for the two peaks corresponding to the two types of bcr-abl junctions: the b2-a2 type (343 base pairs, 10 patients) was revealed at 9.33 min [standard deviation (SD) = 0.1] and the b3-a2 type (418 base pair, 24 patients) at 10.03 min (SD = 0.25). By quantitative analysis we found that there is great interpatient variability in bcr-abl expression at diagnosis: the median value of the amount of bcr-abl transcript was 78,000 bcr-abl transcript/microgram total RNA ranging from 17,300 to 750,000. The amount of bcr-abl transcript at diagnosis was related to the number of blast cells (mean value 128,859 vs. 331,722 in patients with 0% blast cells and > 1% blast cells, respectively; p = 0.004) and Sokal's score (mean value 156,865 vs. 408,800 in patients with Sokal's score < 0.8 and > 1.2, respectively; p = 0.003). INTERPRETATION AND CONCLUSIONS: Our results confirm that CE analysis offers greater resolution and enhanced sensitivity for detection and quantification of bcr-abl PCR product in the study of this leukemia. Qualitative analysis by CE of bcr-abl product provides a rapid technique (less than 20 min) for the analysis of subnanogram amounts of DNA fragments. CE run times are short, the capillary can be re-used and full automation may be feasible with data acquisition by a computer-controlled step. Competitive/quantitative analysis of bcr-abl as analyzed by CE allowed fewer reactions and more precise quantification.

1070 myeloablative megatherapy procedures followed by stem cell rescue for neuroblastoma: 17 years of European experience and conclusions. European Group for Blood and Marrow Transplant Registry Solid Tumour Working Party.

1070 myeloablative procedures followed by stem cell rescue for neuroblastoma are reviewed. These 1070 procedures are part of the European Group for Blood and Marrow Transplant (EBMTG) registry from the last 17 years (in 4536 patients). In 1070 neuroblastoma patients, survival at 2 years was 49%, at 5 years, 33% and relapses were observed as late as 7 years post-BMT (bone marrow transplant). However, 5-year survivors after megatherapy with BMT for stage 4 disease do have an 80% chance of becoming a long-term survivor. When BMT had been used in first complete response (CR1) no salvage was possible, whereas 15% survivors may be seen if BMT is used for the first time at relapse. Infants with stage 4 neuroblastoma had a 17% toxic death rate and indication in this group is exceptional and not recommended. In a matched cohort (17 allogeneic and 34 autologous), autologous stem cell rescue (SCR) was shown to be at least equal to allogeneic SCR. Multivariate analysis of clinical prognostic factors in children with stage 4 disease over 1 year showed that event-free survival was mainly influenced by two adverse factors before the megatherapy procedure: persisting skeleton lesions (99Tc and/or mIBG scan positive) as well as persisting bone marrow (BM) involvement.

Phase II study of intensive chemotherapy with carboplatin, ifosfamide and etoposide plus recombinant human granulocyte colony-stimulating factor and sequential radiotherapy in locally advanced, unresectable non-small-cell lung cancer.

From June 1991 to August 1994, 61 patients with stage III unresectable non-small-cell lung cancer (NSCLC; 16 cases of stage IIIA with N2 bulky disease and 45 cases of stage IIIB) were treated with ifosfamide given i.v. at 3 g/m2 on day 1, carboplatin given i.v. at 200 mg/m2 on days 1 and 2, etoposide given i.v. at 120 mg/m2 on days 1-3 (ICE) and recombinant human granulocyte colony-stimulating factor (rhG-CSF) given s.c. at 5 micrograms/kg on days 4-13. Chemotherapy was given every 3 weeks for up to three cycles and, unless the disease progressed, was followed by thoracic radiotherapy on the tumor volume (total dose 60 Gy) and mediastinum (40 Gy). All patients had measurable or evaluable unresectable disease and a performance status (Eastern Cooperative Oncology Group) of 0-1. Only 61% of the enrolled patients received the full program of chemoradiotherapy according to the study design. At the end of sequential chemo-radiotherapeutic treatment, 41% of the patients had an objective response (24 partial responses and 1 complete response), 31% showed no change and 28% had progressive disease. The response rate noted for patients in stage IIIA with N2 bulky disease and that recorded for patients in stage IIIB did not differ significantly. The median time to progression was 5.4 months and the median survival was 8.2 months, with the 1-year survival rate being 31%. Sites of progression were mostly intrathoracic. Haematological toxicity was the main side effect, with grade III-IV thrombocytopenia being reported in 24% of the 165 courses of intensive ICE chemotherapy given. Febrile neutropenia was described in six courses (three patients). Non-haematological toxicities and radiotherapy-related side effects were generally mild and easily manageable. In conclusion, in unresectable stage III NSCLC a short program of moderately intensified ICE chemotherapy with rhG-CSF protection followed by sequential radiotherapy failed to increase the percentage of objective responses and reached a median survival comparable with that previously achieved with standard doses.

Fingerprinting of HLA class I genes for improved selection of unrelated bone marrow donors.

The degree of matching of HLA genes between the selected donor and recipient is an important aspect of the selection of unrelated donors for allogeneic bone marrow transplantation (UBMT). The most sensitive methods currently used are serological typing of HLA class I genes, mixed lymphocyte culture (MLC), IEF and molecular genotyping of HLA class II genes by direct sequencing of PCR products. Serological typing of class I antigenes (A, B and C) fails to detect minor differences demonstrated by direct sequencing of DNA polymorphic regions. Molecular genotyping of HLA class I genes by DNA analysis is costly and work-intensive. To improve compatibility between donor and recipient, we have set up a new rapid and non-radioisotopic application of the 'fingerprinting PCR' technique for the analysis of the polymorphic second exon of the HLA class I A, B and C genes. This technique is based on the formation of specific patterns (PCR fingerprints) of homoduplexes and heteroduplexes between heterologous amplified DNA sequences. After an electrophoretic run on non-denaturing polyacrylamide gel, different HLA class I types give allele-specific banding patterns. HLA class I matching is performed, after the gel has been soaked in ethidium bromide or silver-stained, by visual comparison of patients' fingerprints with those of donors. Identity can be confirmed by mixing donor and recipient DNAs in an amplification cross-match. To assess the technique, 10 normal samples, 22 related allogeneic bone marrow transplanted pairs and 10 unrelated HLA-A and HLA-B serologically matched patient-donor pairs were analysed for HLA class I polymorphic regions. In all the related pairs and in 1/10 unrelated pairs, matched donor-recipient patterns were identified. This new application of PCR fingerprinting may confirm the HLA class I serological selection of unrelated marrow donors.

Combined use of growth factors to stimulate the proliferation of hematopoietic progenitor cells after autologous bone marrow transplantation for lymphoma patients.

We studied the kinetic response and concentration of bone marrow (BM) progenitor cells of patients with lymphoid malignancies submitted to autologous bone marrow transplantation (ABMT), treated with a granulocyte-colony-stimulating factor (G-CSF)/interleukin-3 (IL-3) combination. The results were compared with those of lymphoma patients receiving the same pretransplant conditioning regimen followed by G-CSF alone. Recombinant human (rh)G-CSF was administered as a single subcutaneous (s.c.) injection at the dose of 5 micrograms/kg/day from day + 1 after reinfusion of autologous stem cells, while rhIL-3 was added from day +6 at the dose of 10 micrograms/kg/day s.c. (overlapping schedule). In both groups (i.e. G-CSF- and G-CSF/IL-3-treated patients), cytokine administration was discontinued when the absolute neutrophil count was > 0.5 x 10(9)/l of peripheral blood for 3 consecutive days. Following treatment with the CSF combination, the percentage of marrow CFU-GM and erythroid progenitors (BFU-E) in the S phase of the cell cycle increased from 9.3 +/- 2 to 33.3 +/- 12% and from 14.6 +/- 3 to 35 +/- 6%, respectively (p < 0.05). The number of actively cycling megakaryocyte progenitors (CFU-MK and BFU-MK) also increased. Conversely, G-CSF augmented the proliferative rate of CFU-GM (22.6 +/- 6% compared to a baseline value of 11.5 +/- 3%; p < 0.05) but not of BFU-E, CFU-MK or BFU-MK, and the increase in S-phase CFU-GM was significantly lower than that observed in the posttreatment samples of patients receiving IL-3 in addition to G-CSF. The absolute number of both CFU-GM and BFU-E/ml of BM was significantly augmented after treatment with G-CSF/IL-3 but not G-CSF alone. Similarly, administration of the cytokine combination resulted in a higher number of CD34+ cells and their concentration was significantly greater than that observed in the posttreatment samples of G-CSF patients. We also investigated the responsiveness to CSFs, in vitro, of highly enriched CD34+ cells, collected after priming with G-CSF in vivo (i.e. after 5 days of G-CSF administration). Our results demonstrated that pretreatment with G-CSF modified the response of BM cells to subsequent stimulation with additional CSFs. When the hematological reconstitution of patients treated with G-CSF/ IL-3 was compared to that of individuals receiving G-CSF alone, the addition of IL-3 resulted in a significant improvement in granulocyte and platelet recovery, a lower transfusion requirement and shorted hospitalization. In conclusion, our results indicate that in vivo administration of two cytokines increases the proliferative our results indicate that in vivo administration of two cytokines increase the proliferative our results rate and concentration of BM progenitor cells better than G-CSF alone and support a role for growth factor combinations for accelerating hematopoietic recovery after high-dose chemotherapy.

Psychiatric and psychosocial concomitants of abnormal illness behaviour in patients with cancer.

BACKGROUND: Previous studies of medically ill patients suggest that abnormal illness behaviour (i.e. high hypochondriasis, disease conviction, dysphoria and irritability) is associated with depressive symptoms. The present study was carried out in order to examine more in detail the role of psychiatric and psychosocial variables in moulding abnormal illness behaviour in patients with cancer. METHODS: Two-hundred and one newly diagnosed cancer patients were submitted to a semistructured interview to assess past and current psychiatric disorders (DSM-III-R) and social support. Self-report questionnaires were also given in order to evaluate psychological stress symptoms (Symptom Check List-90-R-SCL-90-R), external locus of control (ELC) and illness behaviour (Illness Behaviour Questionnaire-IBQ). RESULTS: A pattern of abnormal illness behaviour was shown in patients with a life-time history of psychiatric disorders (n = 33) and in those with a current DSM-III-R diagnosis (n = 101). IBQ dimensions were associated with SCL-90-R, ELC and low social support. The patients' tendency to deny life events other than cancer was related both to the progression of the illness and to their receiving chemotherapy. CONCLUSIONS: The study confirms the association between psychological disorders and abnormal illness behaviour and points out a role for personality variables (external locus of control) and low social support in favouring maladaptive responses to cancer.

Concomitant and sequential administration of recombinant human granulocyte colony-stimulating factor and recombinant human interleukin-3 to accelerate hematopoietic recovery after autologous bone marrow transplantation for malignant lymphoma.

PURPOSE: To assess the safety, tolerability, and hematopoietic efficacy of sequential and concomitant administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) and recombinant human interleukin-3 (rhIL-3), to accelerate reconstitution of hematopoiesis following myeloablative chemotherapy and autologous bone marrow transplantation (ABMT) for heavily pretreated lymphoma patients. PATIENTS AND METHODS: Fifty-four consecutive patients with refractory or relapsed non-Hodgkin's lymphoma (NHL; n = 30) and Hodgkin's disease (HD; n = 24) were studied. Two different conditioning regimens were used for ABMT: carmustine, cyclophosphamide, etoposide, and cytarabine (BAVC) and carmustine, melphalan, etoposide, and cytarabine (BEAM) for NHL and HD, respectively. Patients were enrolled sequentially onto one of three treatment groups: group 1, G-CSF (5 micrograms/kg/d subcutaneously [SC]) from day +1 after reinfusion of autologous marrow (n = 23); group 2, G-CSF from day +1 combined with IL-3 (10 micrograms/kg/d SC) from day +6 (n = 22, overlapping schedule); and group 3, G-CSF treatment discontinued at day +6 before initiation of IL-3 administration (n = 9, sequential schedule). In the three groups, growth factor(s) was administered until the granulocyte count was greater than 0.5 x 10(9)/L for 3 consecutive days. RESULTS: The study cytokines were generally well tolerated. No side effects were observed when G-CSF was given alone. Four of 31 patients (12.9%) who received SC IL-3 had one severe adverse event defined as World Health Organization (WHO) grade 3 to 4 toxicity (fever, n = 2; pulmonary toxicity, n = 2) and were withdrawn from the study. Groups 2 and 3 did not differ as for treatment tolerability, whereas we observed a trend toward a faster hematopoietic recovery when IL-3 was administered concomitant with G-CSF from day 6 (ie, group 2). Pooled together, patients who received IL-3 showed a median time to achieve a granulocyte count greater than 0.1 and greater than 0.5 x 10(9)/L of 8 and 11 days, respectively. The median time to an unsupported platelet count greater than 20 and 50 x 10(9)/L was 15 and 20 days, respectively, and only one patient did not reach a normal platelet count. The median number of days to hospital discharge was 16 after ABMT (range, 12 to 29). When the hematologic reconstitution of patients in groups 2 and 3 was compared with that of patients in group 1, the addition of IL-3 resulted in a significant improvement of multilineage hematopoietic recovery, lower transfusion requirements, a lower number of documented infections, and shorter hospitalizations. CONCLUSION: We conclude that the combination of G-CSF and IL-3 is safe and well tolerated in intensively pretreated lymphoma patients, undergoing ABMT and results in rapid hematopoietic recovery following myeloablative chemotherapy.

Autologous bone marrow transplantation in late first complete remission improves outcome in acute myelogenous leukemia.

We evaluated the role of ABMT in late 1st CR AML adult patients using busulfan plus cyclophosphamide as preparative regimen. Fifty-one adult patients (mean age 36 years, range 15-59) with AML underwent ABMT in 1st CR. Three of them had a prior diagnosis of myelodysplastic syndrome; one patient had a secondary leukemia. The median interval between CR and ABMT was 8 months (range 4-20). Patients received busulfan, 4 mg/kg/day for 4 days plus cyclophosphamide 50 mg/kg/day for 4 days or 60 mg/kg/day for 2 days. No maintenance chemotherapy was administered after ABMT. Median days to reach 0.5 x 10(9)/I PMN and 20 x 10(9)/I platelets were 26 (range 12-250) and 74 (range 16-740), respectively. No transplant-related deaths were observed. Five-year actuarial overall survival rate is 76.9%; actuarial leukemia-free survival rate is 70.6%. Mean follow-up from ABMT is 35 months. Leukemia-free survival of this group was compared with that of 38 non-transplanted patients younger than 60 years, who maintained a CR longer than 8 months in the same period. This analysis shows a statistically significant difference in favor of ABMT patients. These results suggest that, even if performed late after 1st CR as post-remission intensification, ABMT can improve the outcome of AML patients.

Unrelated donor marrow transplantation: initial experience of the Italian bone marrow transplant group (GITMO).

From 1 September 1988 to 30 September 1993, a search for an unrelated donor (URD) was started for 633 Italian patients. Eighty-five of them (13%) were transplanted. Despite the introduction of more strict criteria for the selection of compatible donors, the percentage of patients who reached transplant increased significantly after December 1992. For patients who started a search before and after January 1993, respectively the probability of transplant by 8 and 16 months from search activation was 4 and 10%, compared to 22 and 37% (P = 0.0001). The average intervals between search activation and graft were 15 and 8 months respectively, for the first and second group (P = 0.0001). Data of 75 consecutive transplants performed up to March 1994 were analyzed. Actuarial 2-year survival was 15% for patients grafted before 1992 and 40% for those grafted after January 1992. In this latter period, survival of patients with malignant and non-malignant disorders was 32 and 67%, respectively. In univariate analysis, patients younger than 16 years (P = 0.01), patients grafted after 1992 (P = 0.01) and patients receiving the marrow from a 6-antigen matched donor (P = 0.01) showed a higher survival probability. Multivariate analysis did not show any difference, probably due to the low number of patients and to short follow-up. The adoption of stricter and more accurate HLA-matching criteria and the consequent reduction of deaths related to acute GVHD were the main reasons for the improvement of survival observed in patients grafted after 1992.

Psychological stress symptoms before and after autologous bone marrow transplantation in patients with solid tumors.

This study sought to examine patterns of changes of psychological stress symptoms in autologous bone marrow transplantation (ABMT) recipients. Forty-nine patients affected by solid tumors were assessed using the Symptom Questionnaire on admission to hospital (before high-dose chemotherapy and ABMT) and before discharge. Symptoms of anxiety and anger tended to decrease and relaxation of improve over time. Nevertheless, on admission to hospital 30-50% of the patients reported severe to moderate symptoms of anxiety and depression. Before discharge, the prevalence was still high (20-35%). The implications of these findings are discussed in terms of the need to monitor the evolution of emotional functioning of cancer patients undergoing ABMT.

Interferon-alpha in the treatment of chronic myeloid leukemia. A summary and an update of the Italian studies.

Six-hundred patients were recruited between 1986 and 1991 for studies of the treatment of Ph positive chronic myeloid leukemia (CML) with interferon-alpha (IFN-alpha). The median survival of the patients who were assigned to treatment with IFN-alpha was 6 years or longer than 6 years, and was more than the survival of the patients who were assigned to conventional chemotherapy. Survival prolongation was significantly related with the achievement of a cytogenetic response. IFN-alpha treatment was not harmful for subsequent allogeneic or autologous bone marrow transplantation.
