Abstract
In recent years, the number of approved and investigational agents that can be safely administered for the treatment of lymphoma patients for a prolonged period of time has substantially increased. Many of these novel agents are evaluated in early-phase clinical trials in patients with a wide range of malignancies, including solid tumors and lymphoma. Furthermore, with the advances in genome sequencing, new "basket" clinical trial designs have emerged that select patients based on the presence of specific genetic alterations across different types of solid tumors and lymphoma. The standard response criteria currently in use for lymphoma are the Lugano Criteria which are based on [18F]2-fluoro-2-deoxy-D-glucose positron emission tomography or bidimensional tumor measurements on computerized tomography scans. These differ from the RECIST criteria used in solid tumors, which use unidimensional measurements. The RECIL group hypothesized that single-dimension measurement could be used to assess response to therapy in lymphoma patients, producing results similar to the standard criteria. We tested this hypothesis by analyzing 47 828 imaging measurements from 2983 individual adult and pediatric lymphoma patients enrolled on 10 multicenter clinical trials and developed new lymphoma response criteria (RECIL 2017). We demonstrate that assessment of tumor burden in lymphoma clinical trials can use the sum of longest diameters of a maximum of three target lesions. Furthermore, we introduced a new provisional category of a minor response. We also clarified response assessment in patients receiving novel immune therapy and targeted agents that generate unique imaging situations.

Abstract
CAR T-cells are autologous T-cells transduced with a chimeric antigen receptor (CAR). The CAR contains an antigen recognition part (originating from an antibody), a T-cell receptor transmembrane and cytoplasmic signalling part, and one or more co-stimulatory domains. While CAR T-cells can be directed against any tumour target, most experience thus far has been obtained with targeting of the B-cell antigen CD19 that is expressed by B-cell acute lymphocytic leukaemia, chronic lymphocytic leukaemia and other B-cell lymphomas. The first clinical results are promising, although there are profound differences in response between patients with different haematological malignancies. Treatment-related side effects have been observed that require specific management. This review will explain the mechanism of action, summarise the experience to date and point out future directions for this hopeful new addition to the therapeutic armamentarium in the treatment of lymphoproliferative B-cell malignancies.

Abstract
Radioimmunotherapy (RIT) represents an exciting new therapeutic option for the treatment of B-cell non-Hodgkin's lymphoma (NHL), emerging at a time when significant advances have been made in NHL classification, molecular genetics and treatment. Despite recent treatment advances, including the use of fludarabine phosphate-based combination chemotherapies, able to eradicate minimal residual disease, there remains much room for improvement. The incorporation of RIT into treatment schedules is an attractive option to exploit the extreme sensitivity of lymphoma cells to irradiation. In this supplement, we examine the potential future roles for RIT in the light of past and present therapies, existing RIT clinical data and the unique attributes of radiolabeled monoclonal antibodies.

Abstract
Targeting the CD20 antigen on B lymphocytes with the monoclonal antibody rituximab has greatly improved the outcome of patients with B-cell malignancies. Despite the success of rituximab, resistance occurs in about half of the patients, resulting in non-response to treatment or early relapse of the original disease. A better understanding of the mechanism of rituximab resistance has lead to the development of novel, improved anti-CD20 antibodies. This review describes the development of CD20-targeted therapy from its historical background towards the next generation of anti-CD20 monoclonal antibodies and explains new strategies to overcome resistance.

Abstract
Adoptive transfer of T lymphocytes is an attractive strategy for many experimental treatment strategies for cancer. Unfortunately, manipulated T cells could be responsible for serious adverse events. Retroviral CD20-transduced T cells may be able to control these unwanted effects. CD20-positive cells are sensitive to rituximab (RTX), a monoclonal antibody specific for CD20. This permits their selective elimination in vivo in case of adverse events. To this end, a system is required that permits efficient and safe transduction of donor T cells and effective elimination of CD20-positive T cells. We constructed different CD20-encoding retroviral vectors and investigated the impact of inclusion of the woodchuck post-transcriptional regulatory element (WPRE) and the chicken hypersensitivity site 4 insulator elements on the levels, homogeneity and stability of CD20 expression. Importantly, inclusion of either WPRE or insulator elements in the retroviral vector resulted in a dramatic improvement in the stability of CD20 expression. The insulator element also led to a much more homogeneous level of CD20 expression. We also show the efficient elimination of the CD20-transgenic T cells via RTX by different effector mechanisms. In conclusion, we have constructed CD20-encoding retroviral vectors with improved efficiency and safety profiles, which can be used as a suicide strategy.

Abstract
7507 Background: Standardized response criteria are needed to interpret and compare clinical trials, and for approval of new therapeutic agents by regulatory agencies. Methods: The International Working Group (IWG) criteria (Cheson et al, JCO 17:1244, 1999) were widely adopted but were reevaluated because of limitations identified, and recent advances, notably FDG-PET, immunohistochemistry (IHC) and flow cytometry. Results: We propose the following modifications for non-Hodgkin’s lymphoma (NHL) and Hodgkin lymphoma (HL). For predictably PET avid histologies (PA)(e.g., diffuse large B-cell NHL (DLBCL), HL, follicular (FL) and mantle cell lymphoma (MCL), PET pretreatment is strongly encouraged to define sites of disease, but not required. For histologies not predictably PET+ (NPA), PET should only be done if response is an endpoint. Although PET performed after ≥1 cycles of chemotherapy correlates with treatment efficacy, in the absence of data that altering therapy because of PET results improves outcome, mid-treatment PET should only be done in a clinical trial. PET is essential to assess response in DLBCL and HL, but only in FL and MCL if response is the endpoint. For NPA histologic subtypes, PET should only be used if PET+ prior to therapy and response is a major endpoint. Present data are inadequate to recommend PET for routine post-treatment surveillance. The new definition for CR includes: 1) no signs or symptoms of disease; 2) PET- in a PA lymphoma, or negative CT in NPA lymphoma. 3) Normal bone marrow by morphology, or if indeterminate, negative by IHC, flow and/or molecular genetic studies. CR unconfirmed (CRu) is no longer included. PR is defined as 1) ≥ 50% decrease in tumor size, but PET+ at prior PA sites, or 2) ≥ 50% decrease in tumor size, but CT+ and PET- if PET- prior to treatment. Bone marrow is irrelevant if positive pre-treatment. Stable disease is neither PR nor progressive disease, PET+ only at prior sites of disease. Progressive/ relapsed disease requires ≥ 50% increase in disease or new lesions that are PET+ if PA lymphoma. PET does not replace a biopsy before initiating new therapy. Conclusions: We hope these revised recommendations will be adopted by study groups and regulatory agencies to facilitate the development of new and more effective therapies to improve patient outcome. No significant financial relationships to disclose.

Abstract
Identification of a broad array of leukaemia-associated antigens is a crucial step towards immunotherapy of haematological malignancies. However, it is frequently hampered by the decrease of proliferative potential and functional activity of T cell clones used for screening procedures. Transfer of the genes encoding the T cell receptor (TCR) alpha and beta chains of leukaemia-specific clones into primary T cells may help to circumvent this obstacle. In this study, transfer of two minor histocompatibility antigen (minor H antigen)-specific TCRs was performed and the feasibility of the use of TCR-transgenic T cells for identification of minor H antigens through cDNA library screening was investigated. We found that TCR-transgenic cells acquired the specificity of the original clones and matched their sensitivity. Moreover, the higher scale of cytokine-production by TCR-transgenic T cells permits the detection of either small amounts of antigen-positive cells or cells expressing low amounts of an antigen. When applied in equal numbers, TCR-transgenic T cells and the original T cell clones produced similar results in the screening of a cDNA library. However, the use of increased numbers of TCR-transgenic T cells allowed detection of minute amounts of antigen, barely discernible by the T cell clone. In conclusion, TCR-transfer generates a large amount of functional antigen-specific cells suitable for screening of cDNA expression libraries for identification of cognate antigens.

Abstract
BACKGROUND CD40-activated B lymphocytes have been used successfully as potent APC for the induction of T-cell responses. However, the 3T3-CD40L cell line, regularly used for engagement of CD40 on the B-cell surface, is a potential source of xenoantigens. This may affect the specificity of T cells stimulated with CD40-activated B cells, especially when generation of T-cell lines specific for endogenously processed Ag is desired. METHODS To develop a system that allows efficient expansion of B cells in the absence of sources of xenoantigens, we created a human 293-CD40L-sCD40L cell line that produces soluble CD40L and expresses CD40L on the cell surface. B cells from patients with hematologic malignancies were expanded on the 293-CD40L-sCD40L cells and used for stimulation of either naive or in vivo primed donor T cells in three HLA-identical patient-donor combinations. RESULTS The 293-CD40L-sCD40L cell line was able to stimulate B-cell growth with an efficiency superior to that of the commonly used 3T3-CD40L cell line. In all cases T-cell lines and, subsequently, T-cell clones were generated that showed reactivity against patient and not donor B cells, suggesting their specificity for minor histocompatibility antigens (mHAg). DISCUSSION B cells activated with GMP grade 293-CD40L-sCD40L can be used in a variety of applications. In particular, they may be suitable for ex vivo stimulation of T cells prior to donor lymphocyte infusion (DLI), which may enhance its graft versus leukemia (GvL) effect.

In all cases T-cell lines and, subsequently, T-cell clones were generated that showed reactivity against patient and not donor B cells, suggesting their specificity for minor histocompatibility antigens (mHAg). DISCUSSION B cells activated with GMP grade 293-CD40L-sCD40L can be used in a variety of applications. In particular, they may be suitable for ex vivo stimulation of T cells prior to donor lymphocyte infusion (DLI), which may enhance its graft versus leukemia (GvL) effect.

Abstract
BACKGROUND Non-Hodgkin's lymphoma (NHL) comprises a group of related haematological malignancies, predominantly of B-cell origin, which have been described as indolent or aggressive according to their clinical course. Standard treatment for indolent NHL consists of conventional chemotherapy, but, although long-term remissions may occur, most patients will die of their disease. Radioimmunotherapy (RIT) is a novel modality for treating indolent NHL, using monoclonal antibodies to target tumour cells with systemic, low-dose radiation. (90)Y-Ibritumomab tiuxetan (Zevalin); Schering AG, Berlin, Germany), the first RIT approved for use in relapsed/refractory indolent NHL, comprises the murine anti-CD20 monoclonal antibody ibritumomab, covalently linked to the high-energy beta-emitter, yttrium-90, by the chelator, tiuxetan. MATERIALS AND METHODS A multidisciplinary consensus workshop of European clinicians who had taken part in clinical trials of (90)Y-ibritumomab tiuxetan was convened to develop recommendations for the clinical preparation and administration of (90)Y-ibritumomab tiuxetan in Europe. The workshop was held in anticipation of European Medicines Agency approval of this agent, which was gained in 2004 for adult patients with rituximab-relapsed or refractory CD20(+) follicular B-cell NHL. RESULTS AND CONCLUSIONS This article summarises the consensus recommendations developed for hemato-oncologists.

Abstract
Purpose To determine whether interferon (IFN) -α2, when given with or following chemotherapy, influences response rate, remission duration, and survival in newly diagnosed patients with follicular lymphoma. Patients and Methods Ten phase III studies evaluating the role of IFN-α2 in 1,922 newly diagnosed patients with follicular lymphoma were analyzed. Updated individual patient data were used to perform meta-analyses for response, survival, and remission duration. Results The addition of IFN-α2 to initial chemotherapy did not significantly influence response rate. An overall meta-analysis for survival showed a significant difference in favor of IFN-α2, but also showed significant heterogeneity between studies. Further analyses were carried out in order to explain this heterogeneity, and to define the circumstances in which IFN-α2 prolonged survival. The survival advantage was seen when IFN-α2 was given: (1) in conjunction with relatively intensive initial chemotherapy (2P = .00005), (2) at a dose ≥ 5 million units (2P = .000002), (3) at a cumulative dose ≥ 36 million units per month (2P = .000008), and (4) with chemotherapy rather than as maintenance therapy (P = .004). With regard to remission duration, there was also a significant difference in favor of IFN-α2, irrespective of the intensity of chemotherapy used, IFN dose, or whether IFN was given as a maintenance strategy or with chemotherapy. Conclusion When given in the context of relatively intensive initial chemotherapy, and at a dose ≥ 5 million units (≥ 36 × 106 units per month), IFN-α2 prolongs survival and remission duration in patients with follicular lymphoma.

Abstract
Killer lymphocytes play a central therapeutic role in graft-versus-leukemia following allogeneic hematopoietic stem cell transplantation (HSCT). The Perforin/Granzyme and FAS/CD95 pathways are of crucial importance in tumor cell elimination by killer cells. In this study, we have examined whether hematological malignancies are resistant to perforin and anti-FAS antibodies. Leukemic cells were studied from 29 patients suffering either from acute or chronic myeloid leukemia (AML or CML), acute or chronic lymphoid leukemia, or non-Hodgkin's lymphoma. An average of 49 vs 5% of specific cell killing was found when using perforin vs anti-FAS antibodies, respectively. Interestingly, resistance towards both perforin and anti-FAS antibodies was found exclusively in leukemic cells from patients with myeloid leukemia. Analysis of leukemic cells from patients with CML, suffering from leukemia relapse after HSCT and given donor lymphocyte infusion (DLI) to induce remission, indicated that the effectiveness of treatment with DLI was not associated with sensitivity of leukemic cells to perforin. In conclusion, resistance towards anti-FAS antibodies is a common phenomenon in leukemia/lymphoma, whereas perforin resistance occurs only in myeloid leukemia. However, as a single parameter, perforin resistance does not appear to be suitable to predict the outcome of DLI.

Abstract
The use of bone marrow derived stromal cells (BMSC's) for bone tissue engineering has gained much attention as an alternative for autologous bone grafting. Little is known however, about the survival and differentiation of the cells, especially in the clinical application. The aim of this study was to develop a method to trace goat BMSC's in vivo. We investigated retroviral genetic marking, which allows stable expression of the label with cell division. Goat BMSC's were subjected to an amphotropic envelope containing a MoMuLV-based vector expressing the human low affinity nerve growth factor receptor (DeltaLNGFR). Labeling efficiency and effect on the cells were analyzed. Furthermore, transduced cells were seeded onto porous ceramic scaffolds, implanted subcutaneously in nude mice and examined after successive implantation periods. Flow cytometry indicated a transduction efficiency of 40-60%. Immunohistochemistry showed survival and subsequent bone formation of the gene-marked cells in vivo. Besides, marked cells were also found in cartilage and fibrous tissue. These findings indicate the maintenance of the precursor phenotype following gene transfer as well as the ability of the gene to be expressed following differentiation. We conclude that retroviral gene marking with DeltaLNGFR is applicable to trace goat BMSC's in bone tissue engineering research.

Abstract
Expression of Bcl-2 in multiple myeloma is associated with resistance to chemotherapeutic drugs. Conversely, suppression of Bcl-2 enhanced the chemosensitivity of myeloma cells in vitro. G3139 is an antisense oligodeoxynucleotide targeted to the first six codons of the Bcl-2 mRNA open reading frame. In this study, G3139 was delivered as a continuous intravenous infusion for 7 days at a fixed dose of 7 mg/kg/day in combination with VAD (vincristine, adriamycin, and dexamethasone) chemotherapy. In total, 10 heavily pretreated patients with refractory myeloma participated in this trial, including eight patients with VAD refractory disease. The combination of G3139 and VAD was feasible and well tolerated. Seven patients (70%) responded including four patients (40%) with a partial response and three patients (30%) with a minor response. Median progression-free survival was 6 months (range, 2-7+ months) and median overall survival has not been reached. G3139 downregulated Bcl-2 protein levels in peripheral blood circulating myeloma cells, B cells, T cells, and monocytes. These results indicate that G3139 may overcome classical resistance and restore sensitivity of myeloma tumor cells to VAD chemotherapy.

Abstract
The presence of replication-competent retrovirus (RCR) in retroviral-based gene therapy products poses a potential safety risk for patients. Therefore, RCR testing of clinical gene therapy products and monitoring of patients enrolled in gene therapy trials is required to assure viral safety. The requirement to test ex vivo-transduced cells originates from the presumed amplification of adventitious RCR during the transduction procedure. However, data on the capacity of different cell types to do so are lacking. In this study, we sought to analyze the amplification potential of primary human T lymphocytes after infection with amphotropic MLV-based RCR. The total number of viral particles produced after 1 or 2 weeks was measured by a quantitative 4070A env-specific RT-PCR assay. The fraction of infectious replication-competent viral particles was analyzed in the PG-4 S+L- assay. From this study, we conclude that the total number of viral particles RCR produced by T lymphocytes is 2-4 logs lower than the number produced by NIH-3T3 cells. Surprisingly, less than 1% of the viral particles produced by primary T lymphocytes appeared to be infectious, while nearly all virions produced by NIH-3T3 were. We conclude that primary human T lymphocytes are low producers of MLV-based amphotropic RCR.

Abstract
The objectives of this study were to estimate the incidence of idiosyncratic neutropenia and agranulocytosis in England and Wales and to evaluate their risk factors and outcomes. The study was conducted using data from the General Practice Research Database. All cases of idiosyncratic neutropenia or agranulocytosis were identified and the incidence was estimated. This was followed by a nested case-control study, estimating odds ratios with drug exposure from conditional logistic regression. From 1987 to 1999, 3,224 patients with idiosyncratic neutropenia (50 with agranulocytosis) were identified. The incidences of neutropenia and agranulocytosis were estimated to be 120 and 7 cases per million people per year, respectively. The adjusted odds ratios for neutropenia were 34.7 (95% confidence interval 12.0-99.7) for current users of thyroid inhibitors, 9.5 (4.4-20.8) for users of disease-modifying antirheumatic drugs, and 7.6 (4.9-11.9) for users of aminosalicylates. Other drugs with statistically significantly increased risks of neutropenia included antibacterial drugs, non-opioid analgesics, NSAIDs, antidepressants, ulcer-healing drugs, and anti-epileptics. The increase in risk of neutropenia predominantly occurred during the first months of treatment. For most drugs investigated in this study, there was no relationship to daily dose. The excess 1-year mortality was low among neutropenia and agranulocytosis cases and mostly explained by the underlying disease state. In conclusion, the highest risks of neutropenia were generally found in patients starting treatment. The excess 1-year mortality was low among neutropenia and agranulocytosis cases and can be mostly explained by the underlying disease state.

Abstract
Allogeneic stem cell transplantation (SCT) is one of the most expensive medical procedures. However, only a few studies to date have addressed the costs of HLA-identical sibling transplantation and only one study has reported costs of unrelated transplantation. No recent cost analysis with a proper follow-up period and donor identification expenses is available on related or voluntary matched unrelated donor (MUD) SCT for adult AML or ALL. Therefore, we calculated direct medical (hospital) costs based on 97 adults who underwent HLA-identical sibling bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT), and patients who received a graft from a MUD between 1994 and 1999. The average costs per transplanted patient were Euro 98,334 (BMT), Euro 151,754 (MUD), and Euro 98,977 (PBSCT), including donor identification expenses, 2 years follow-up and costs of patients who were not transplanted after they had been planned to receive an allograft. The majority of these costs was generated during the hospitalisation for graft infusion. For MUD transplants, nearly one-third of these costs was spent on the search for a suitable donor. For patients who were alive after 2 years, cumulative expenses were calculated to be Euro 103,509 (BMT), Euro 173,587 (MUD), and Euro 105,906 (PBSCT).

Abstract
Hereditary mutations associated with hematologic malignancies are rare. Heterozygous mutations affecting the hematopoietic transcription factor CBFA2 (also AML1/RUNX1) were recently reported to be associated with familial platelet disorder with predisposition to acute myeloid leukemia (FPD/AML, MIM 601399). A new 3-generation family with FPD/AML with a novel CBFA2 mutation is described. In this family, AML was diagnosed in a second-generation male. After allogeneic stem cell transplantation from his human leukocyte antigen-identical sister, a donor-derived, genetically identical leukemia developed in the recipient and the donor. Sequencing analysis identified a G-to-T transition within the CBFA2 gene, which involves codon 198, encoding a conserved aspartic acid within the DNA- binding Runt domain. Three of 5 siblings affected with the FPD/AML trait harbored the mutation in a heterozygous form. This experience underscores the necessity of performing mutation analysis of the CBFA2 gene before sibling allogeneic transplantation in families with FPD/AML.

Abstract
BACKGROUND Multiple myeloma is an incurable disease and after several lines of chemotherapy, patients enter a phase in which no standard treatment options are available. The poor outlook of these patients requires mild, palliative therapy with low toxicity. Previously used regimens either require frequent hospital attendance, lack efficacy or have significant toxicity. METHODS In the current study, daily low dose, oral cyclophosphamide (100 mg) and prednisone (10-20 mg; CP) were administered to patients with advanced myeloma. Forty-two patients with progressive disease after melphalan-based and VAD treatment were enrolled. RESULTS Objective responses were observed in 29 of 42 (69%) patients. In responding patients, median overall survival and progression-free survival were 22.2 months and 15.0 months, respectively. In non-responders, median OS was 3.5 months only. Side-effects were limited. Cytopenia was the most frequent event (8/29) prompting dose reduction. CP had to be stopped permanently in four patients (two cytopenia, two infections). CONCLUSION Orally administered, low dose continuous CP is a feasible, effective and well-tolerated regimen in the management of advanced multiple myeloma.

Abstract
Introduction of the Herpes simplex virus thymidine kinase (HSV-tk) gene into target cells renders them susceptible to killing by ganciclovir (GCV). We are studying the use of HSV-tk-transduced T lymphocytes in the context of hematopoietic stem cell transplantation. We have previously shown, in vitro and in vivo, the occurrence of transduced cells resistant to GCV due to a deletion within HSV-tk. This deletion, a consequence of the presence of cryptic splice donor and acceptor sites, originates in the retroviral producer cell. Here we adopt two different methods that introduce third-base degenerate changes at the cryptic splice sites and so prevent splicing. Consequently, the HSV-tk protein is unaltered and the sensitivity of the target cells to GCV is preserved. The use of this mutated HSV-tk should reduce the likelihood of the development of resistant genetically modified cells during clinical trials.

Abstract
PURPOSE Long-term survivors of Hodgkin's disease who received mantle-field irradiation at a young age have a strongly increased risk of developing breast cancer. The purpose of this study was to investigate whether this increased risk was substantially greater among women heterozygous for a germline mutation in the ataxia-telangiectasia gene (ATM). MATERIALS AND METHODS Thirty-two patients were selected who had developed breast cancer at least 10 years following irradiation for Hodgkin's disease before the age of 45 years. In these patients, the complete open reading frame of the ATM gene was analysed for the presence of germline mutations using the protein truncation test and two mutation-specific tests, followed by genomic sequencing. RESULTS No A-T disease causing germline mutations were found in these selected Hodgkin patients. However, several alternative splicing events were detected which might influence protein expression levels. CONCLUSIONS The data suggest that truncating mutations in the ATM gene are not a major component underlying the increased risk of breast cancer following Hodgkin's disease.

Abstract
PURPOSE To quantify the long-term risk of second primary cancers (SCs) in patients diagnosed with Hodgkin's disease (HD) during adolescence or young adulthood. PATIENTS AND METHODS The risk of SCs was assessed in 1,253 patients diagnosed with HD before the age of 40 years and treated in two Dutch cancer centers between 1966 and 1986. The median follow-up duration was 14.1 years. RESULTS In all, 137 patients developed SCs, compared with 19.4 cases expected on the basis of incidence rates in the general population (relative risk [RR] = 7.0; 95% confidence interval, 5.9 to 8.3). The 25-year actuarial risk of SC overall was 27.7%. The RR of solid tumors increased greatly with younger age at the first treatment of HD, not only for breast cancer but also for all other solid tumors, with RRs of 4.9, 6.9, and 12.7 for patients first treated at ages 31 to 39 years, 21 to 30 years, and </= 20 years, respectively. Among patients first treated at the age of 20 years or younger, the RR of developing a solid tumor before the age of 40 years was significantly greater than the RR of solid tumor development at ages 40 to 49 years (RR = 27.9 v RR = 4.2; P =.0001). Patients who received salvage chemotherapy had significantly greater risk of solid cancers other than breast cancer than did patients whose treatment was restricted to initial radiotherapy or initial combined-modality treatment (RR = 9.4 and 4.7, respectively; P =. 004). CONCLUSION After more than 20 years of follow-up, the risk of solid tumors is still much greater in survivors of HD than in the population at large. Reassuringly, the greatly increased risk of solid tumors in patients who were young (</= 20 years of age) at the first treatment seems to decrease as these patients grow older. Our data suggest that chemotherapy may increase the risk of solid tumors from radiotherapy.

Abstract
The in vivo elimination of suicide gene-expressing tumor cells with prodrug treatment can induce protective immunity against wild-type tumors. In this study, we determined the efficacy and safety of the in vivo elimination of HSVtk expressing cells with ganciclovir treatment of a bystander cell killing-insensitive leukemic cell line. The retroviral construct pLTk+NeoDeltaMo, containing the HSVtk gene and the NeoR gene in a bicistronic unit, was introduced into rat leukemic LT12 cells. LT12/Tk+N cells showed a 1000- to 10 000-fold increased sensitivity to ganciclovir in vitro. In vitro mixing experiments demonstrated that LT12 cells were not susceptible to bystander cell lysis by LT12/Tk+N-2 cells exposed to ganciclovir. Rats injected s.c. with cloned LT12/Tk+N-2 cells developed tumors reaching a diameter of 3-4 cm after 40 days. Rats treated with gan- ciclovir twice daily for 5 consecutive days starting at day 7 did not develop s.c. tumors. Large established s.c. LT12/Tk+N-2 tumors completely regressed after ganciclovir treatment. However, recurrences of s.c. tumors were observed that were no longer sensitive to ganciclovir treatment. In vitro analysis of aspirates from the recurrent tumors demonstrated loss of HSVtk expression. In vitro culture of LT12/Tk+N-2 cells in soft agar in the presence of ganciclovir indicated that the frequency with which HSVtk-loss variants occurred is approximately one per 104 cells. The in vivo occurrence of HSVtk-loss variants escaping ganciclovir-induced elimination may have important implications for vaccination protocols using HSVtk gene expressing tumor cells that are not susceptible to bystander cell killing.

Abstract
The clinical use of autologous marrow transplantation in acute myeloid leukemia (AML) has been hampered by the inability to collect adequate numbers of cells after remission induction chemotherapy and the notably delayed hematopoietic regeneration following autograft reinfusion. Here we present a study in which the feasibility of mobilizing stem cells was investigated in newly diagnosed AML. Among 96 AML patients, 76 patients (79%) entered complete remission. Mobilization was undertaken with low dose and high dose schedules of G-CSF in 63 patients, and 54 patients (87%) were leukapheresed. A median of 2.0 x 10(6) CD34+ cells/kg (range 0.1-72.0) was obtained in a median of three leukaphereses following a low dose G-CSF schedule (150 microg/m2) during an average of 20 days. Higher dose regimens of G-CSF (450 microg/m2 and 600 microg/m2) given during an average of 11 days resulted in 28 patients in a yield of 3.6 x 10(6) CD34+ cells/kg (range 0-60.3) also obtained following three leukaphereses. The low dose and high dose schedules of G-CSF permitted the collection of 2 x 10(6) CD34-positive cells in 46% and 79% of cases respectively (P = 0.01). Twenty-eight patients were transplanted with a peripheral blood stem cell (PBSC) graft and hemopoietic repopulation was compared with the results of a previous study with autologous bone marrow. Recovery of granulocytes (>0.5 x 10(9)/l, 17 vs 37 days) and platelets (>20 x 10(9)/l; 26 vs 96 days) was significantly faster after peripheral stem cell transplantation compared to autologous bone marrow transplantation. These results demonstrate the feasibility of PBSCT in the majority of cases with AML and the potential advantage of this approach with respect to hemopoietic recovery.

Abstract
Standardized guidelines for response assessment are needed to ensure comparability among clinical trials in non-Hodgkin's lymphomas (NHL). To achieve this, two meetings were convened among United States and international lymphoma experts representing medical hematology/oncology, radiology, radiation oncology, and pathology to review currently used response definitions and to develop a uniform set of criteria for assessing response in clinical trials. The criteria that were developed include anatomic definitions of response, with normal lymph node size after treatment of 1.5 cm in the longest transverse diameter by computer-assisted tomography scan. A designation of complete response/unconfirmed was adopted to include patients with a greater than 75% reduction in tumor size after therapy but with a residual mass, to include patients-especially those with large-cell NHL-who may not have residual disease. Single-photon emission computed tomography gallium scans are encouraged as a valuable adjunct to assessment of patients with large-cell NHL, but such scans require appropriate expertise. Flow cytometric, cytogenetic, and molecular studies are not currently included in response definitions. Response rates may be the most important objective in phase II trials where the activity of a new agent is important and may provide support for approval by regulatory agencies. However, the goals of most phase III trials are to identify therapies that will prolong the progression-free survival, if not the overall survival, of the treated patients. We hope that these guidelines will serve to improve communication among investigators and comparability among clinical trials until clinically relevant laboratory and imaging studies are identified and become more widely available.

Abstract
The in vivo effect of the radiochemoprotectant Amifostine on the therapeutic efficacy of marrow ablative treatment with cyclophosphamide (CP) and total body irradiation (TBI) followed by bone marrow transplantation (BMT) was studied in normal rats as well as in the Brown Norway rat acute myelocytic leukaemia (BNML) model. In normal rats, when the dose of TBI was escalated and the CP dose was kept constant, pretreatment with Amifostine yielded a positive dose modification factor of 1.26. No significant improvement was found after Amifostine pretreatment when the TBI dose was kept constant and CP dose escalated. When leukaemic rats received CP as the only antileukaemia treatment, Amifostine pretreatment did not lead to a reduction in the antileukaemic efficacy of CP, although protection against treatment-related mortality was observed. In the CP only groups, 9 out of 40 animals died of treatment-related toxicity, compared with none of the 40 animals in the Amifostine pretreatment groups. When applying the maximum tolerated treatment of CP and TBI in various combinations to leukaemic rats, 25 out of 36 rats died from treatment-related toxicity, whilst pretreatment with Amifostine reduced this to 11 out of 36, (P = 0.002). Of those animals which survived the CP + TBI conditioning treatment, 10 out of 25 in the Amifostine pretreatment group were cured, versus 8/11 in the CP + TBI only control group (P = 0.146). In conclusion, incorporation of Amifostine as a radiochemoprotectant in a marrow-ablative conditioning regimen allows the use of escalated doses of chemoradiotherapy without reducing the antileukaemic efficacy.

Abstract
The treatment of choice for patients over 60 years of age with aggressive non-Hodgkin's lymphoma (NHL) consists of chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP). Because of poor tolerance, dose reductions and delays occur frequently. However, because of the relatively low dose intensity significantly more patients die of refractory or relapse lymphoma. If it is intended to cure these patients, unmitigated CHOP chemotherapy should be applied. When needed additional supportive care can be provided.

Abstract
BACKGROUND Chromosome banding techniques and in situ hybridization reveal the majority of chromosomal aberrations. However, difficulties remain in cases of highly contracted chromosomes, poor quality of the metaphases or the presence of markers with the involvement of several chromosomes. Here, it is demonstrated that reverse painting can be applied successfully starting with bone marrow cells from primary acute myelocytic leukemias (AML). METHODS This was accomplished by culturing the leukemic cells with a cocktail of various growth factors, which yielded sufficient numbers of cells in cycle to harvest chromosomes for sorting. Aberrant chromosomes were flow-sorted and amplified by degenerate oligonucleotide-primed PCR. The resulting products were labeled by nick-translation and hybridized on normal metaphase spreads. RESULTS Two patients with marker chromosomes in their leukemia cells were analyzed in detail. The hybridization pattern displayed the composition of the aberrant sorted chromosome. Results were compared with conventional cytogenetic analyses that were performed on material obtained from the same aspirate. The reverse-painting technique enabled identification of aberrations that were not detected by conventional cytogenetic analysis. CONCLUSIONS Primary AML cells can be cultured in vitro, using optimal culture conditions, facilitating the production of high quality flow karyotypes, suitable for sorting of marker chromosomes to produce DOP-PCR derived chromosome painting probes for reverse painting. Valuable additional cytogenetic information can thus be obtained about complex chromosomal rearrangements or structural aberrations that could not be completely resolved by conventional cytogenetic analysis.

Abstract
The severe combined immunodeficient (SCID) mouse model may be used to evaluate new approaches for the treatment of acute myeloid leukemia (AML). We have previously demonstrated the killing of SCID mouse leukemia initiating cells by in vitro incubation with human GM-CSF fused to Diphtheria toxin (DT-huGM-CSF). In this report, we show that in vivo treatment with DT-huGM-CSF eliminates AML growth in SCID mice. Seven cases of AML were studied. SCID mice were treated intraperitoneally with the maximally tolerated dose of 75 microg/kg/day for 7 days. Antileukemic efficacy was determined at days 40 and 80 after transplantation, by enumerating the percentages of human cells in SCID bone marrow using flow cytometry and short tandem repeat polymerase chain reaction (STR-PCR) analysis. Four out of seven AML cases were sensitive to in vivo treatment with DT-huGM-CSF at both evaluation time points. In three of these cases, elimination of human cells was demonstrated by flow cytometry and STR-PCR. One AML case showed moderate sensitivity for DT-huGM-CSF, and growth of the two remaining AML cases was not influenced by DT-huGM-CSF. Sensitivity was correlated with GM-CSFR expression. Our data show that DT-huGM-CSF can be used in vivo to reduce growth of AML and warrant further development of DT-huGM-CSF for the treatment of human AML.

Abstract
In this study, we describe the efficiency of second gene translation in bicistronic constructs containing either a short (36bp) synthetic intercistron or known internal ribosomal entry sites (IRES). Experiments were performed using two different gene combinations: Herpes simplex virus-thymidine kinase (HSV-TK) and neomycine (NEO) or human glucocerebrosidase (hGC) and a methotrexate (MTX) resistant mutant dihydrofolate reductase (DHFR). We demonstrate that upon transfection, second gene translation is efficient using either an IRES or a 36-bp intercistron. Infection with retrovirus carrying the TK and NEO genes linked via a 36-bp intercistron resulted in both G418R (NEO expression) and gancyclovir (GCV) sensitivity (TK expression), indicating that both genes were expressed and thus that the genomic DNA and RNA of this bicistronic construct were intact. Likewise, retrovirus carrying the hGC and mutant DHFR gene separated by a short intercistron was harvested from MTXR murine PsiCRE cells. However, infection of PA317 cells with this virus supernatant did not result in the presence of hGC enzyme activity in these murine cells. Proviral DNA and RNA analyses indicated that the hGC coding region was lost from the original construct in the infected PA317 cells. In contrast, retrovirus carrying the hGC and DHFR cDNAs was linked via an IRES functioned as expected. Based on these results, we conclude that the efficiency of second gene translation using short synthetic intercistrons might prove useful in bicistronic constructs, depending on the gene combination used.

Abstract
The objectives of the present study were to investigate the prognostic value of the International Prognostic Index (IPI) at relapse in the 215 patients with intermediate- or high-grade non-Hodgkin's lymphoma (NHL) included in the PARMA trial. The IPI at relapse was available in 204 (95%) of these patients. Response rates to 2 courses of DHAP were 77%, 54%, 55%, and 42% in patients with an IPI of 0, 1, 2 and 3, respectively (P <.02), whereas complete response (CR) rates were 33%, 29%, 20%, and 0% in the same groups of patients (P <.03). With a median follow-up period of 79 months, overall survival (OS) at 5 years was 46%, 25%, 25%, and 11% in these four groups (P <.001). One hundred nine patients responding to 2 courses of DHAP were randomized to receive either BEAC (carmustine, etoposide, cytarabine, cyclophosphamide and mesna) followed by autologous bone marrow transplantation (ABMT) or 4 additional courses of DHAP: IPI at relapse was found highly correlated to OS in patients treated in the DHAP arm (5-year OS: 48%, 21%, 33%, and 0% for IPI 0, 1, 2, and 3, respectively; P =.006), but not in the BEAC arm (5-year OS: 51%, 47%, 50%, and 50% for IPI 0, 1, 2, and 3, respectively; P =.90). OS was significantly superior in the BEAC arm as compared with the DHAP arm in patients with an IPI >0 (P <.05), but not in patients with an IPI of 0. In conclusion, these results show that IPI correlates to response and overall survival in patients with aggressive NHL in relapse and enables us to identify patients with a significantly different outcome among those treated with conventional chemotherapy alone.

Abstract
PURPOSE The purpose of this study was to investigate the prognostic value of time to relapse in 188 adult patients with intermediate- or high-grade non-Hodgkin's lymphoma (NHL) included on the Parma trial at the time of their first relapse. PATIENTS AND METHODS The median follow-up of these patients is 102 months after registration onto the Parma study. Time to relapse was calculated from initial diagnosis, and a cutoff of 12 months was used to separate 77 patients defined as early relapse from 111 patients defined as late relapse. RESULTS Patients with early and late relapses had significantly different overall response rates to salvage therapy with two courses of dexamethasone, high-dose cytarabine, and cisplatin (DHAP; 40% v 69%; P=.00007) and different 8-year survival rates (13% v 29%; P=.00001). Features at relapse with a negative prognostic value in univariate analysis were higher than normal lactic dehydrogenase (LDH) levels, tumor size greater than 5 cm, Ann Arbor stages III to IV, and Karnofsky score less than 80%. Therefore, multivariate analyses were performed. Time to relapse (P=.001) and LDH levels at relapse (P=.003) had independent prognostic value, whereas tumor size did not reach statistical significance in the logistic model that predicted overall response after two courses of DHAP. The study of prognostic factors for overall survival (OS) and progression-free survival (PFS) confirmed the prognostic value of time to relapse (P < .0001 for OS and P=.005 for PFS) independent of response or treatment after two courses of DHAP. CONCLUSION Time to relapse may be used to stratify patients at time of first relapse of intermediate to high-grade non-Hodgkin's lymphoma.

Abstract
We have previously demonstrated that diphtheria toxin (DT) fused to human GM-CSF effectively eliminates human long-term leukemia initiating cells in SCID mice. However, because huGM-CSF does not react with the murine GM-CSF receptor possible side-effects to nonleukemic tissues could not be analyzed in the AML/SCID model. To overcome this problem, we used murine GM-CSF fused to DT and studied the therapeutic index in the rat leukemia model BNML/LT12. In DT-mGM-CSF dose escalation experiments, severe dose-dependent toxicity to organs such as liver, kidney and lung was observed. Therefore, the antileukemic effects were evaluated with the lower doses. Daily intraperitoneal bolus injections of 75 microg/kg/day for 7 days induced a 3 log leukemic cell kill. The dose of 75 microg/kg/day had no effect on the hemopoietic progenitor cell subsets. These in vivo studies show that the DT-GM-CSF fusion protein can be used for specifically targeting leukemic cells and thus has potential as a therapeutic agent in the treatment of AML.

Abstract
Ultraviolet-B (UVB) irradiation is known to inhibit lymphocyte activity and consequently to reduce the incidence of graft-versus-host disease (GVHD) in experimental models for allogeneic bone marrow transplantation (BMT). GVHD is frequently associated with morbidity and mortality, but also with the beneficial graft-versus-leukemia (GVL) effect, demonstrated by a reduction in the incidence of leukemia relapse. In this study, we investigated whether UVB treatment of allogeneic T cells could prevent GVHD while sparing the beneficial GVL effect following allogeneic BMT in the Brown Norway myelocytic leukemia (BNML) rat model analogous to human acute myelocytic leukemia (AML). The dose of UVB required to abolish lethal GVHD in the rat allogeneic BMT model (WAG/Rij donors into BN recipients) was 4000 J/m2. However, this UVB dose simultaneously abrogated all GVL activity mediated by the T cells in the graft, while the radio-protective capacity of rat BM cells was strongly reduced. The number of allogeneic BM cells required to protect lethally irradiated BN rats was increased 50 to 100-fold. It is concluded that UVB acts as a non-selective form of T cell inactivation, and that UVB pretreatment of an allogeneic marrow graft is unlikely to be useful clinically as a preventive measure for GVHD, since other means of reduction of the number of functional T cells are less damaging to bone marrow stem cells.

Abstract
PURPOSE Data of a multicenter study in non-Hodgkin's lymphoma (NHL) by the Dutch Hovon Group were reanalyzed to assess the risk of relapse in the central nervous system (CNS) related to the international risk index for NHL. In addition we assessed the risk for CNS disease in relation to the presence of bone marrow localisation at presentation. DESIGN We focused our analysis on those patients reaching a complete remission (CR). Two hundred eighty-six patients (histological subtypes D-H Working Formulation) and with stages II-IV were analyzed. One hundred ninety-three (67%) patients reached a CR. RESULTS Relapse occurred in 78 patients of whom 10 patients with concomitant or isolated CNS disease. According to the international risk index the following observations were made: low risk (n = 38) nine out of 34 CR relapsed, none had CNS involvement; low-intermediate risk (n = 115) 27 out of 83 CR relapsed, three had CNS involvement; high-intermediate risk (n = 110) 37 out of 68 CR relapsed, six had CNS involvement; high risk (n = 22) four out of seven CR relapsed, one had CNS involvement. Two out of 10 developed isolated CNS disease and eight out of 10 patients developed CNS disease with systemic relapse. CONCLUSION Our data show that the number of CNS relapses after CR is relatively low (10 out of 193 = 5%), with an increasing incidence in the high-risk groups according to the international risk index. The occurrence of CNS relapse seems to be related to the risk of systemic relapse after CR. No subgroup could be discriminated in which prophylactic treatment would be of substantial benefit.

Abstract
PURPOSE Interferon alfa has shown significant activity in patients with low-grade malignant non-Hodgkin's lymphoma (NHL). In 1985, we initiated a prospective randomized study in which the potential benefit of interferon alfa given as maintenance treatment was investigated after tumor load reduction was achieved with chemoradiotherapy in patients with advanced low-grade malignant non-Hodgkin's lymphoma. PATIENTS AND METHODS The study involved 347 patients with stage III or IV disease, 315 satisfying the eligibility criteria. All were treated with a regimen of cyclophosphamide, vincristine, and prednisone (CVP) given every 3 weeks for eight cycles. Thereafter, patients were eligible for iceberg irradiation. Finally, all patients were completely restaged, and responding and stable-disease patients were then randomized, 122 to interferon alfa-2a maintenance, 3 million U three times weekly for 1 year; and 120 to no further treatment. RESULTS Seventy-nine percent of the patients response to CVP, ie, 45% complete remissions (CR) and 34% partial remissions (PR). In the group of randomized patients, the response rate after CVP plus or minus radiotherapy was 90%. As compared with control patients, patients in the interferon (IFN) maintenance group had a tendency toward a prolonged time to progression (TTP) (median, 132 v 87 weeks; P = .054, adjusted for response to CVP). However, overall survival was similar in both groups. Interferon was well tolerated. The median dose of IFN actually received corresponded to 90% of the planned cumulative dose. The treatment had to be stopped because of toxicity in 16 patients (15% of the patients in whom IFN was started). CONCLUSION Interferon maintenance treatment in the phase of minimal residual disease of patients with advanced low-grade malignant NHL increased TTP at the borderline of statistical significance, without remarkable toxicity. However, overall survival was not influenced.

Abstract
PURPOSE The hematopoietic growth factors (HGFs) introduced into induction chemotherapy (CT) of acute myeloid leukemia (AML) might be of benefit to treatment outcome by at least two mechanisms. HGFs given on days simultaneously with CT might sensitize the leukemic cells and enhance their susceptibility to CT. HGFs applied after CT might hasten hematopoietic recovery and reduce morbidity or mortality. MATERIALS AND METHODS We set out to evaluate the use of granulocyte-macrophage colony-stimulating factor (GM-CSF; 5 microg/kg) in a prospective randomized study of factorial design (yes or no GM-CSF during CT, and yes or no GM-CSF after CT) in patients aged 15 to 60 years (mean, 42) with newly diagnosed AML. GM-CSF was applied as follows: during CT only (+/-, n = 64 assessable patients), GM-CSF during and following CT (+/+, n = 66), no GM-CSF (-/-, n = 63), or GM-CSF after CT only (-/+, n = 60). RESULTS The complete response (CR) rate was 77%. At a median follow-up time of 42 months, probabilities of overall survival (OS) and disease-free survival (DFS) at 3 years were 38% and 37% in all patients. CR rates, OS, and DFS did not differ between the treatment groups (intention-to-treat analysis). Neutrophil recovery (1.0 x 10(9)/L) and monocyte recovery were significantly faster in patients who received GM-CSF after CT (26 days v 30 days; neutrophils, P < .001; monocytes, P < .005). Platelet regeneration, transfusion requirements, use of antibiotics, frequency of infections, and duration of hospitalization did not vary as a function of any of the therapeutic GM-CSF modalities. More frequent side effects (eg, fever and fluid retention) were noted in GM-CSF-treated patients predominantly related to the use of GM-CSF during CT. CONCLUSION Priming of AML cells to the cytotoxic effects of CT by the use of GM-CSF during CT or accelerating myeloid recovery by the use of GM-CSF after CT does not significantly improve treatment outcome of young and middle-aged adults with newly diagnosed AML.

Abstract
We studied the cell kill induced by granulocyte-macrophage colony-stimulating factor (GM-CSF ) fused to Diphtheria Toxin (DT-GM-CSF ) in acute myeloid leukemia (AML) samples and in populations of normal primitive hemopoietic progenitor cells. AML samples from three patients were incubated in vitro with 100 ng/mL DT-GM-CSF for 48 hours, and AML cell kill was determined in a proliferation assay, a clonogenic assay colony-forming unit-AML (CFU-AML) and a quantitative long-term bone marrow (BM) culture ie, the leukemic-cobblestone area forming cell assay (L-CAFC). To measure an effect on cells with in vivo leukemia initiating potential DT-GM-CSF exposed AML cells were transplanted into immunodeficient mice. In two out of three samples it was shown that all AML subsets, including those with long-term abilities in vivo (severe combined immunodeficient mice) and in vitro (L-CAFC assay) were reduced in number by DT-GM-CSF. Cell kill induced by DT-GM-CSF could be prevented by coincubation with an excess of GM-CSF, demonstrating that sensitivity to DT-GM-CSF is specifically mediated by the GM-CSF receptor. Therefore, binding and internalization of GM-CSF probably occur in immature AML precursors of these two cases of AML. The third AML sample was not responsive to either GM-CSF or DT-GM-CSF. The number of committed progenitors of normal bone marrow (burst-forming unit-erythroid, colony-forming unit granulocyte- macrophage, and cobble stone area forming cell [CAFC] week 2) and also the number of cells with long-term repopulating ability, assayed as week 6 CAFC, were unchanged after exposure to DT-GM-CSF (100 ng/mL, 48 hours). These studies show that DT-GM-CSF may be used to eliminate myeloid leukemic cells with long-term potential in vitro and in immunodeficient mice, whereas normal hemopoietic stem cells are spared.

Abstract
The potential to selectively eliminate acute myeloid leukaemia (AML) cells with the GM-CSF-diphtheria toxin fusion protein (DT-GM-CSF) was studied under conditions of autonomous proliferation in vitro with no growth factors (GFs) added and after growth stimulation with a mixture of human (hu)G-CSF, huIL-3 and huSCF. DNA synthesis was maximally inhibited after 48 h exposure to DT-GM-CSF. Cell viability and AML colony forming ability in vitro were reduced. 18/22 samples were found to be sensitive to DT-GM-CSF, with 50% inhibition of DNA synthesis (ID50) at concentrations ranging from 0.1 to 16 ng/ml, and four samples were minimally or not sensitive to DT-GM-CSF (ID50 > or = 99 ng/ml). From the 15 samples which showed autonomous proliferation, 13 were sensitive to inhibition of proliferation by DT-GM-CSF. The level of GM-CSF receptor (GM-CSFR) expression was determined by flow cytometry after labelling with specific antibodies for the alpha and beta subunits. Although the toxicity to DT-GM-CSF was specifically mediated by the GM-CSFR, no correlation was found between the level of expression of the GM-CSFR alpha or beta subunit and the sensitivity for DT-GM-CSF. These in vitro studies show that the DT-GM-CSF fusion protein can be used for specifically targeting and eliminating leukaemic cells in the majority of AML cases.
