It is yet undetermined whether patients with different hematological malignancies have different propensities to infectious complications after high-dose chemotherapy (HDC) and autologous hematopoietic stem cell transplantation (HSCT). We retrospectively analyzed 136 cycles of HDC and autologous HSCT in 114 patients with acute myeloid leukemia (AML, 24 cycles), non-Hodgkin's lymphoma/Hodgkin's disease (NHL/HD, 55 cycles), and multiple myeloma (MM, 57 cycles) with respect to early infectious complications. Median duration of neutropenia was longer in patients with AML and NHL/HD than in patients with MM (11 days vs 8 days) and after conditioning including total body irradiation (TBI) compared with chemotherapy only preparative regimens (11 days vs 7 days). Fever requiring antimicrobial therapy was observed in 88 percent of cycles, with fever of unknown origin (FUO) accounting for 60 percent of febrile episodes. There was no proven fungal infection, but one case of probable invasive pulmonary aspergillosis. Microbiologically documented infections were seen in 29 percent and clinically documented infections in 11 percent. Response to first-line empirical antibiotic therapy was better for FUO than for documented infections (70 percent vs 40 percent). Patients with TBI as part of their conditioning regimen had more overall infections than patients without TBI (96 percent vs 82 percent). There were no differences with respect to the type or incidence of infections between patients with AML, NHL/HD, and MM. Patients with different hematological malignancies have similar rates of early infectious complications after HDC and autologous HSCT. TBI may be associated with an increased risk for infections in the early post-transplant period.

We describe the toxicity and efficacy of donor lymphocyte infusions (DLIs) given to 81 patients (median age, 50 years) after reduced-intensity conditioning (RIC) transplantations performed at 16 centers in the United Kingdom. The diseases treated included non-Hodgkin lymphoma (NHL; n = 29), chronic myeloid leukemia (CML; n = 12), myeloma (n = 11), acute myeloid leukemia (AML; n = 10), and chronic lymphocytic leukemia (CLL; n = 9). Eighty-eight percent received stem cells from sibling donors. The patients received 130 infusions (median, 1; range, 1-4). Indications for DLI were unsatisfactory response/disease progression in 51 patients, mixed chimerism in 18, preemptive in 10, and other in 2. Graft hypoplasia was uncommon (11%). Grade II to IV graft-versus-host disease (GVHD) occurred in 23 of 81 patients (28%) and limited and extensive chronic GVHD in 5 of 69 and 18 of 69 evaluable patients (total incidence 33%). Conversion from mixed to full donor chimerism occurred in 19 of 55 evaluable patients (35%) at a median of 48 days after the DLI; partial responses occurred in 6 patients (total response rate 45%). Eighteen of 51 (35%) patients with measurable disease after stem cell transplantation had a complete response (2 molecular), and 5 a partial response (total response rate 45%). Eleven of 17 evaluable complete responders had full donor chimerism. Eight of 13 patients with follicular NHL had complete responses as did 4 of 12 patients with CML. Clinical and chimeric responses correlated strongly with acute and chronic GVHD. Forty-seven patients (58%) survive at a median of 508 days after transplantation (range, 155-1171 days) with a median Karnofsky score of 90. Thirty-four patients (42%) died at a median of 211 days after transplantation with the major causes being progressive disease (26%) and GVHD (9%). Further systematic studies are required to determine the efficacy and optimum use of DLI for patients with each disease treated by nonmyeloablative stem cell transplantation.

Cytogenetic studies of patients with therapy-induced acute myeloid leukemia (t-AML) have demonstrated whole chromosome loss or q-arm deletion of chromosomes 5 and/or 7 in a majority of cases. We have established two cell lines, SAML-1 and SAML-2, from two patients who developed t-AML after radiation and chemotherapy for Hodgkin disease. In both cases, the leukemia cells contained 5q deletions. SAML-1 has 58 chromosomes and numerous abnormalities, including der(1)(1qter-->1p22::5q31-->5qter), der(5)(5pter-->5q22::1p22-->1pter), +8, der(13)i(13)(q10)del(13)(q11q14.1), and t(10;11). Fluorescence in situ hybridization (FISH) with unique sequence probes for the 5q31 region showed loss of IL4, IL5, IRF1, and IL3, and translocation of IL9, DS5S89, EGR1, and CSFIR to 1p. SAML-2 has 45 chromosomes, del(5)(q11.2q31) with a t(12;13)ins(12;5), leading to the proximity of IRF1 and RB1, and complex translocations of chromosomes 8 and 11, resulting in amplification of MYC and MLL. Comparative genomic hybridization and spectral karyotyping were consistent with the G-banding karyotype and FISH analyses. Because a potential tumor suppressor(s) in the 5q31 region has yet to be identified, these cell lines should prove useful in the study of the mechanisms leading to the development of t-AML.

To evaluate the frequency and cytogenetic and immunophenotypic features of therapy-related, precursor B-cell acute lymphoblastic leukemia (ALL), 152 cases of immature B-cell ALL were reviewed. These were compared to the frequency of therapy-related acute myeloid leukemia (t-AML) during the same time period. Eight ALL cases with a prior diagnosis of malignancy were identified, including six (4.0%) with prior therapy considered to be therapy-related ALL (t-ALL). The t-ALL cases followed treatment for breast carcinoma (two cases), lung carcinoma (two cases), lymphocyte predominance Hodgkin's disease and follicular lymphoma with a latency period of 13 months to 8 years. All t-ALL cases had a pro-B (CD10-negative) immunophenotype with significantly higher expression of CD15 and CD65, compared to the de novo CD10-positive ALL cases. All six t-ALL cases had MLL abnormalities by fluorescence in situ hybridization, and four showed t(4;11)(q21;q23). These represented half of all 11q23-positive adult ALL cases. During the same time period, 4.9% of all AML cases were considered t-AML. There was a 16.7% frequency of 11q23 abnormalities in the t-AML group. Despite the similar frequency in therapy-related disease among ALL and AML cases, there were differences in the frequency of the diseases and t-ALL represented 12% of all therapy-related leukemias. However, t-ALL represented 46% of all 11q23-positive therapy-related leukemias. The immunogenetic features of t-ALL appear distinct and may aid in identifying more cases of this disease type in the future.

The purpose of this study is to examine the relationship of t(11;16)(q23;p13) to the type of myeloproliferative disorder noted by hematopathology. Previously, t(11;16) has been reported in fewer than 20 patients, all with the diagnosis of therapy-related (secondary) acute myelogenous leukemia (sAML) or myelodysplastic syndrome (MDS). Putative involved genes are the MLL on 11q23 and CBP at 16p13. Data from The University of Texas M. D. Anderson Cancer Center (UTMDACC) Cytogenetics Laboratory revealed 3 patients with t(11;16) observed during the past 5 years. Two of the patients had a prior diagnosis of non-Hodgkin lymphoma (NHL) and had been treated with chemotherapy, which included cyclophosphamide. The other patient presented with de novo AML and no history of cancer or chemotherapy. Two of the 3 patients had t(11;16) as the sole cytogenetic abnormality. One patient had a t(11;16) clone that included t(9;21) and t(10;21) as additional changes. Translocation (11;16) has previously been reported only as being therapy-related. In this study, the t(11;16) was seen in 2 patients with previous lymphomas treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). A single patient with apparently de novo AML constitutes the first reported instance of non-treatment associated t(11;16) AML.

The survival of patients with aggressive non-Hodgkin lymphoma (NHL) is increasing, but the incidence of secondary cancer and late toxicity is poorly defined for those treated with cyclophosphamide-hydroxydaunomycin/doxorubicin-Oncovin-prednisone (CHOP)-like chemotherapy. From February 1984 to January 1998, 2837 patients with aggressive NHL received the control-arm chemotherapy adriamycin-cyclophosphamide-vindesine-bleomycin-prednisone (ACVBP) in 3 consecutive Groupe d'Etude des Lymphomes de l'Adulte (GELA) studies. With a median follow-up time of 74 months, the 5-year overall and event-free survival rates were 60% and 52%. Two hundred two occurrences of nonneoplastic late toxicity were reported, resulting in a 5.35% cumulative probability of incidence at 7 years. Eighty-one second tumors developed, for which the 7-year cumulative incidence rate was 2.75%; 64 were solid tumors, and 17 were hematologic malignancies. In multivariate analysis, age was the only risk factor for the second development of cancer. Epidemiologic analysis allowed a comparison of this NHL group with the general population. Considering all tumors, no excess of second cancer was observed. In the male population, however, there was an excess of lung cancer (standardized incidence ratio [SIR], 2.45; P <.001) and myelodysplastic syndrome/acute myelocytic leukemia (MDS/AML) (SIR, 5.65; P =.006), and in the female population there was an excess of MDS/AML (SIR, 19.9; P <.001). With a long follow-up, the ACVBP regimen was highly effective for the treatment of aggressive NHL. Increases occurred in secondary MDS/AML and in lung cancer among men.

We assessed the prognostic importance of the platelet count 100 days post transplant of 107 consecutive patients receiving ablative allogeneic bone marrow transplant (BMT) between 7/96 and 12/00 who survived at least 100 days. Diagnoses included AML (n=36), chronic myelogenous leukemia (n=27), NHL (n=14), ALL (n=16), MDS (n=9), aplastic anemia (n=3), and one Hodgkin's disease and myelofibrosis each. In total, 64% were in remission or in chronic phase or had aplastic anemia (good risk), and 36% had active disease at the time of transplant (bad risk). In all, 70% were matched sibling transplants and 30% were matched unrelated donor transplants. The mean follow-up for the patients remaining alive is 48 months. Survival was powerfully influenced by the 100-day platelet count: 4-year survival was 19% for patients with a platelet count <30 x 10(9)/l; 41% for patients with a platelet count of 30-50; and 72% for those with a platelet count >50 (P<0.001; log-rank test). In a multivariable analysis, the most powerful risk factors for mortality after allogeneic BMT were low 100-day platelet count (P<0.001) and bad risk disease (P=0.009). We conclude that the platelet count 100 days post transplant is a powerful predictor of overall survival.

Diffuse large B-cell lymphoma (DLBCL) accounts for 30-40% of all adult non-Hodgkin's lymphomas, yet the understanding of its underlying genetic abnormalities remains poor. Our present study used the serological analysis of recombinant cDNA expression libraries (SEREX) technique to identify DLBCL-associated antigens. SEREX screening of testis libraries has previously identified cancer-testis antigens (CTAs) that may act as disease-specific targets for immunotherapy. Screening a testis cDNA expression library with serum from a DLBCL patient identified a total of 94 positive clones, representing 28 distinct antigens. Two of these antigens were novel, 8 were previously uncharacterised, and the remainder were proteins of known function. Screening of the antigens with sera from DLBCL (n = 10), acute myeloid leukaemia (AML, n = 10) and chronic myeloid leukaemia (CML, n = 10) patients, alongside normal healthy donor controls (n = 20), revealed that 7 of the antigens were recognised by DLBCL sera but not normal donor sera, whilst 2 of these antigens were also recognised by leukaemic sera. Some of the genes identified here were already known to be transcribed in DLBCL. The mRNA expression of the majority of the remaining antigens was confirmed in DLBCL cell lines using reverse-transcriptase PCR (RT-PCR). Our study identified a number of DLBCL associated antigens that may be suitable as prognostic/diagnostic markers and/or for the immunotherapy of haematologic malignancies.

In the present study, we have assessed, in a comparative manner, the in vitro proliferation and expansion potentials of hematopoietic progenitor cells (HPC) present in mobilized peripheral blood from normal subjects (MPB-n; n = 18) and cancer patients (MPB-c; n = 18). The latter included patients with breast cancer (BrCa; n = 8), Hodgkin disease (HD; n = 4), non-Hodgkin lymphoma (NHL; n = 3), and acute myeloid leukemia (AML; n = 3). Progenitor cells from normal bone marrow (BM) and umbilical cord blood (UCB) were included as controls. HPC, enriched by a negative selection procedure, were cultured for 25 days, in serum-free liquid media in the presence of a cytokine combination including early- and late-acting cytokines. Our results demonstrate that the in vitro biological properties of progenitor cells present in MPB differ, depending on whether they are derived from healthy individuals, from patients with solid tumors, or from patients with hematological neoplasias. Among all cell sources analyzed, UCB-derived progenitors showed the greatest proliferation and expansion potentials (1000-fold increase in total cell numbers on day 15, and a 22-fold increase in myeloid progenitor cell numbers, at day 10). Progenitor cells present in MPB from hematologically normal individuals showed proliferation and expansion potentials comparable to those of HPC from normal BM (500-fold increase in total cell numbers on day 15, and a 14-fold increase in myeloid progenitor cell numbers, at day 10). The proliferation/expansion potentials of MPB progenitors from BrCa patients were also within the normal range, although in the lower levels (327-fold increase in total cell numbers, on day 15, and 11.8-fold increase in myeloid progenitors, at day 10). In contrast, progenitors present in MPB from patients with HD, NHL, and especially AML, showed reduced in vitro capacities (119-, 102-, and 51-fold increase in total cell numbers, respectively; and 8-, 4-, and 2.6-fold increase in myeloid progenitor cells, respectively). To our knowledge, this is the first report in which the in vitro proliferation and expansion potentials of HPC from MPB from normal subjects and cancer patients are assessed simultaneously in a comparative manner.

We assessed late mortality in 854 individuals who had survived 2 or more years after autologous hematopoietic cell transplantation (HCT) for hematologic malignancies. Median age at HCT was 36.5 years, and median length of follow-up was 7.6 years. Overall survival was 68.8% +/- 1.8% at 10 years, and the cohort was at a 13-fold increased risk for late death (standardized mortality ratio [SMR] = 13.0) when compared with the general population. Mortality rates approached those of the general population after 10 years among patients at standard risk for relapse at HCT (SMR = 1.1) and in patients undergoing transplantation for acute myeloid leukemia (AML; SMR = 0.9). Relapse of primary disease (56%) and subsequent malignancies (25%) were leading causes of late death. Relapse-related mortality was increased among patients with Hodgkin disease (HD; relative risk [RR] = 3.6), non-Hodgkin lymphoma (NHL; RR = 2.1), and acute lymphoblastic leukemia (ALL; RR = 6.5). Total body irradiation (RR = 0.6) provided a protective effect. Nonrelapse-related mortality was increased after carmustine (RR = 2.3) and with use of peripheral blood stem cells (RR = 2.4). Survivors were more likely to report difficulty in holding jobs (RR = 9.4) and in obtaining health (RR = 7.7) or life insurance (RR = 8.4) when compared with siblings. Although mortality rates approach that of the general population after 10 years in certain subgroups, long-term survivors of autologous HCT continue to face challenges affecting their health and well-being.
