Abstract
MicroRNA-mediated regulation is critical for the proper development and function of the small intestinal (SI) epithelium. However, it is not known which microRNAs are expressed in each of the cell types of the SI epithelium. To bridge this important knowledge gap, we performed comprehensive microRNA profiling in all major cell types of the mouse SI epithelium. We used flow cytometry and fluorescence-activated cell sorting with multiple reporter mouse models to isolate intestinal stem cells, enterocytes, goblet cells, Paneth cells, enteroendocrine cells, tuft cells, and secretory progenitors. We then subjected these cell populations to small RNA-sequencing. The resulting atlas revealed highly enriched microRNA markers for almost every major cell type (https://sethupathy-lab.shinyapps.io/SI_miRNA/). Several of these lineage-enriched microRNAs (LEMs) were observed to be embedded in annotated host genes. We used chromatin-run-on sequencing to determine which of these LEMs are likely cotranscribed with their host genes. We then performed single-cell RNA-sequencing to define the cell type specificity of the host genes and embedded LEMs. We observed that the two most enriched microRNAs in secretory progenitors are miR-1224 and miR-672, the latter of which we found is deleted in hominin species. Finally, using several in vivo models, we established that miR-152 is a Paneth cell-specific microRNA.NEW & NOTEWORTHY In this study, first, microRNA atlas (and searchable web server) across all major small intestinal epithelial cell types is presented. We have demonstrated microRNAs that uniquely mark several lineages, including enteroendocrine and tuft. Identification of a key marker of mouse secretory progenitor cells, miR-672, which we show is deleted in humans. We have used several in vivo models to establish miR-152 as a specific marker of Paneth cells, which are highly understudied in terms of microRNAs.

Abstract
The therapeutic landscape of chronic myeloid leukemia (CML) has profoundly changed over the past 7 years. Most patients with chronic phase (CP) now have a normal life expectancy. Another goal is achieving a stable deep molecular response (DMR) and discontinuing medication for treatment-free remission (TFR). The European LeukemiaNet convened an expert panel to critically evaluate and update the evidence to achieve these goals since its previous recommendations. First-line treatment is a tyrosine kinase inhibitor (TKI; imatinib brand or generic, dasatinib, nilotinib, and bosutinib are available first-line). Generic imatinib is the cost-effective initial treatment in CP. Various contraindications and side-effects of all TKIs should be considered. Patient risk status at diagnosis should be assessed with the new EUTOS long-term survival (ELTS)-score. Monitoring of response should be done by quantitative polymerase chain reaction whenever possible. A change of treatment is recommended when intolerance cannot be ameliorated or when molecular milestones are not reached. Greater than 10% BCR-ABL1 at 3 months indicates treatment failure when confirmed. Allogeneic transplantation continues to be a therapeutic option particularly for advanced phase CML. TKI treatment should be withheld during pregnancy. Treatment discontinuation may be considered in patients with durable DMR with the goal of achieving TFR.

Abstract
Translation of drug candidates into clinical settings requires demonstration of preclinical efficacy and formal toxicology analysis for filling an Investigational New Drug (IND) application with the US Food and Drug Administration (FDA). Here, we investigate the membrane-associated glucose response protein 78 (GRP78) as a therapeutic target in leukemia and lymphoma. We evaluated the efficacy of the GRP78-targeted proapoptotic drug bone metastasis targeting peptidomimetic 78 (BMTP-78), a member of the D(KLAKLAK)2-containing class of agents. BMTP-78 was validated in cells from patients with acute myeloid leukemia and in a panel of human leukemia and lymphoma cell lines, where it induced dose-dependent cytotoxicity in all samples tested. Based on the in vitro efficacy of BMTP-78, we performed formal good laboratory practice toxicology studies in both rodents (mice and rats) and nonhuman primates (cynomolgus and rhesus monkeys). These analyses represent required steps towards an IND application of BMTP-78 for theranostic first-in-human clinical trials.

Abstract
BACKGROUND Ponatinib is a potent oral tyrosine kinase inhibitor of unmutated and mutated BCR-ABL, including BCR-ABL with the tyrosine kinase inhibitor-refractory threonine-to-isoleucine mutation at position 315 (T315I). We conducted a phase 2 trial of ponatinib in patients with chronic myeloid leukemia (CML) or Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-positive ALL). METHODS We enrolled 449 heavily pretreated patients who had CML or Ph-positive ALL with resistance to or unacceptable side effects from dasatinib or nilotinib or who had the BCR-ABL T315I mutation. Ponatinib was administered at an initial dose of 45 mg once daily. The median follow-up was 15 months. RESULTS Among 267 patients with chronic-phase CML, 56% had a major cytogenetic response (51% of patients with resistance to or unacceptable side effects from dasatinib or nilotinib and 70% of patients with the T315I mutation), 46% had a complete cytogenetic response (40% and 66% in the two subgroups, respectively), and 34% had a major molecular response (27% and 56% in the two subgroups, respectively). Responses were observed regardless of the baseline BCR-ABL kinase domain mutation status and were durable; the estimated rate of a sustained major cytogenetic response of at least 12 months was 91%. No single BCR-ABL mutation conferring resistance to ponatinib was detected. Among 83 patients with accelerated-phase CML, 55% had a major hematologic response and 39% had a major cytogenetic response. Among 62 patients with blast-phase CML, 31% had a major hematologic response and 23% had a major cytogenetic response. Among 32 patients with Ph-positive ALL, 41% had a major hematologic response and 47% had a major cytogenetic response. Common adverse events were thrombocytopenia (in 37% of patients), rash (in 34%), dry skin (in 32%), and abdominal pain (in 22%). Serious arterial thrombotic events were observed in 9% of patients; these events were considered to be treatment-related in 3%. A total of 12% of patients discontinued treatment because of an adverse event. CONCLUSIONS Ponatinib had significant antileukemic activity across categories of disease stage and mutation status.

Abstract
BACKGROUND Granulocyte transfusions (GTXs) have been used successfully as an adjunctive treatment option for invasive infections in some neutropenic patients with underlying hematologic malignancy (HM). PATIENTS AND METHODS We sought to determine the impact of GTX as an adjunct to antifungal therapy in 128 patients with HM and prolonged neutropenia (≥14 days) with a proven or probable invasive aspergillosis (IA) infection by retrospectively reviewing our institutional database. RESULTS Fifty-three patients received GTX and 75 did not. By univariate analysis, patients with invasive pulmonary aspergillosis who received GTX were less likely to respond to antifungal therapy (P = 0.03), and more likely to die of IA (P = 0.009) when compared with the non-GTX group. Among patients who received GTX, 53% developed a pulmonary reaction. Furthermore, IA-related death was associated with the number of GTX given (P = 0.018) and the early initiation of GTX within 7 days after starting antifungal therapy (P = 0.001). By multivariate competing risk analysis, patients who received GTX were more likely to die of IA than patients who did not receive GTX (P = 0.011). CONCLUSIONS Our study suggests that GTX does not improve response to antifungal therapy and is associated with worse outcomes of IA infection in HM patients, particularly those with pulmonary involvement.

Abstract
Homoharringtonine is an alkaloid inhibitor of protein synthesis with activity in myeloid malignancies. We report a phase II pilot study of homoharringtonine in myelodysplastic syndrome (MDS). Induction consisted of homoharringtonine at 2.5 mg/m(2) via continuous infusion for 7 days. Maintenance was given every 4 weeks. Nine patients were enrolled: five with refractory anaemia with excess blasts, two with refractory anaemia with excess blasts in transformation, one each with refractory anaemia and chronic myelomonocytic leukaemia respectively. Median age was 70 years (55-84) and 6 (66%) were male. Per International Prognostic Scoring System (IPSS) two patients were intermediate-1, five intermediate-2 and two high-risk. Median chemotherapy courses were one (1-3). One patient (11%) responded with complete haematological and cytogenetic remission after one course. Eight patients did not respond (four had stable disease, two progressed to acute leukaemia and two died during induction - from aspergillus pneumonia and intracerebral haemorrhage respectively). Grade 3/4 myelosuppression seen in 56% (5/9). Serious non-haematological toxicities included one case of grade 4 left bundle branch heart block and one grade 3 nephrotoxicity. Median time between courses was 42 days (35-72 days). In conclusion homoharringtonine might have clinical activity in some patients with MDS.

Abstract
MK-0457, an Aurora kinase and BCR-ABL inhibitor, was studied on a Phase I/II study in 77 patients with refractory hematologic malignancies. The average number of cycles per patient was 3 (range 1-21). Maximum tolerated doses for a 5-day short infusion and continuous infusion regimens were 40 mg/m(2)/h and 144 mg/m(2)/h, respectively. Drug-related adverse events (AEs) included transient mucositis and alopecia. Eight of 18 patients with BCR-ABL T315I-mutated chronic myelogenous leukemia (44%) had hematologic responses and one of three patients (33%) with Philadelphia chromosome-positive acute lymphoblastic leukemia obtained complete remission. MK-0457 has important activity in patients with leukemias expressing the highly resistant T315I BCR-ABL mutation.

Abstract
BACKGROUND Tumor lysis syndrome (TLS) is a life-threatening disorder characterized by hyperuricemia and metabolic derangements. The efficacy of rasburicase, administered daily for 5 days, has been well established. However, the optimal duration of therapy is unknown in adults. PATIENTS AND METHODS We evaluated the efficacy of rasburicase (0.15 mg/kg) administered as single dose followed by as needed dosing (maximum five doses) versus daily dosing for 5 days in adult patients at risk for TLS. RESULTS Eighty of the 82 patients enrolled received rasburicase; 40 high risk [median uric acid (UA) 8.5 mg/dl; range, 1.5-19.7] and 40 potential risk (UA = 5.6 mg/dl; range, 2.4-7.4). Seventy-nine patients (99%) experienced normalization in their UA within 4 h after the first dose; 84% to an undetectable level (<0.7 mg/dl). Thirty-nine of 40 (98%) patients in the daily-dose arm and 34 of 40 (85%) patients in single-dose arm showed sustained UA response. Six high-risk patients within the single-dose arm required second dose for UA >7.5 mg/dl. Rasburicase was well tolerated; one patient with glucose-6-phosphate dehydrogenase deficiency developed methemoglobinemia and hemolysis. CONCLUSIONS Rasburicase is highly effective for prevention and management of hyperuricemia in adults at risk for TLS. Single-dose rasburicase was effective in most patients; only a subset of high-risk patients required a second dose.

Abstract
Imatinib is the current standard of care in the treatment of chronic myeloid leukemia (CML), inducing durable responses and prolonged progression-free survival. However, plasma exposure to the drug from a given dosing regimen can vary widely among patients. Reasons for this may include incomplete adherence, intrinsic variations in the metabolism of imatinib, and drug-drug interactions. Data from two recent studies have shown a correlation between imatinib trough plasma concentration and clinical response, leading to suggestions that maintaining imatinib blood concentrations above approximately 1000 ng/ml might be associated with improved outcomes. In patients who do not respond as well as expected to initial imatinib treatment, measurement of trough plasma concentration could assist with decisions about whether to increase the dose. Blood-level testing may also be helpful in other clinical scenarios: for example, when poor adherence is suspected, adverse reactions are unusually severe, or there is a possible drug-drug interaction. Further work is required to confirm prospectively the link between imatinib plasma concentrations and response, and to define effective trough concentrations in different patient populations. However, based on the current data, imatinib blood-level testing seems to be a useful aid when making clinical decisions in CML.

Abstract
Myelofibrosis (MF; primary or post-essential thrombocythemia/polycythemia vera) is incurable clonal myeloproliferative disorder, with no effective treatment. Epigenetic changes play an important role in cancer pathogenesis through transcriptional silencing of critical tumor suppressor genes. We conducted a phase-II study to evaluate the activity of DNA methyltransferase inhibitor, 5-azacitidine, in patients with MF. Thirty-four patients (76% previously treated) received 5-azacitidine at 75 mg/m(2) subcutaneously daily for 7 days, every 4 weeks. Twelve (35%) patients had abnormal cytogenetics and 19 (70%) of 27 evaluable patients had JAK2(V617F) mutation. Responses occurred in 8 (24%) patients after a median of 5 months (range, 3-10). Partial response occurred in 1 (3%) patient (duration 22+ months) and clinical improvement in 7 (21%) patients (median duration 4 months; range, 2-8.5). Myelosuppression was the major adverse effect, with grade 3-4 neutropenia in 10 (29%) patients. Global DNA methylation assessed by the long interspersed nucleotide element (LINE) bisulfite/pyrosequencing assay decreased from 53% pretherapy to 44% on day 14 (P=0.0014) and returned to 50% at the end of the first 28-day cycle (P=0.016). 5-azacitidine is relatively well tolerated and results in induction of global hypomethylation in patients with MF, but results in limited clinical activity.

Abstract
PTK787/ZK 222584 (PTK/ZK) is an oral angiogenesis inhibitor targeting vascular endothelial growth factor (VEGF) receptor tyrosine kinases, including VEGFR-1/Flt-1, VEGFR-2/KDR, VEGFR-3/Flt-4, the platelet-derived growth factor receptor tyrosine kinase and the c-kit protein tyrosine kinase. The objective of this Phase I study was to evaluate the safety, tolerability, biologic activity and pharmacologic profile of PTK/ZK administered orally, twice daily, on a continuous dosing schedule in patients with primary refractory or relapsed acute myeloid leukemia (AML), secondary AML, poor-prognosis de novo AML or advanced myelodysplastic syndrome (MDS). Acute myeloid leukemia patients for whom PTK/ZK monotherapy was ineffective could receive PTK/ZK combined with standard induction chemotherapy. Sixty-three patients received PTK/ZK at doses of 500-1000 mg orally b.i.d. Safety and pharmacokinetic data were collected. Responses were evaluated according to standard bone marrow and peripheral blood criteria. At 1000 mg b.i.d., dose-limiting toxicities of lethargy, hypertension, nausea, emesis and anorexia were observed. Other adverse events related to PTK/ZK were dizziness, weakness, fatigue, diarrhea and pruritus; these were generally mild and reversible. Pharmacokinetic data showed that steady state was reached by day 14, there was no accumulation with repeat dosing and there was no significant increase in exposure at steady state beyond the maximum tolerated dose (MTD). Complete remission was observed in five of 17 AML patients treated with PTK/ZK combined with chemotherapy. In conclusion, the MTD of PTK/ZK is 750 mg orally b.i.d. The drug is generally well tolerated and can be given in combination with chemotherapy for patients with MDS and AML.

Abstract
Although imatinib mesylate (IM) is highly effective at inducing complete cytogenetic remission in patients with chronic myelogenous leukemia (CML), it is known to suppress T-cell proliferation in vitro. As cytokines are required for T-cell proliferation, we investigated the effects of IM on cytokine synthesis by T cells of CML patients by assessing cytokine synthesis by activated CD4+ and CD8+ T cells in vitro. The activation of T cells in the whole blood of IM-treated patients (CML-IM) with Staphylococcus enterotoxin B resulted in significantly lower percentages of CD4+ T cells that synthesized interleukin 2 (P = 0.017), interferon-gamma (P = 0.010), and tumor necrosis factor-alpha (P = 0.009) than did the activated T cells of control subjects. The addition of exogenous IM to the cultures of peripheral blood mononuclear cells of CML-IM patients reduced Th1 cytokine synthesis by the CD4+ T cells. Furthermore, IM therapy at clinical doses suppressed the tyrosine phosphorylation of ZAP70. These findings suggest that inhibition of ZAP70 signaling pathway and suppression of Th1 cytokine synthesis by CD4+ T cells required the presence of IM at the time of T-cell activation through the T-cell receptor.

Abstract
Granulocytic sarcoma (GS) is an extramedullary tumor composed of immature myeloid cells. The objectives of this study were to describe the frequency, presenting characteristics, and survival in patients with nonleukemic GS by conducting a review of all untreated patients presenting to the MD Anderson Cancer Center between January 1990 and June 2002. In all, 21 patients with nonleukemic GS, 1520 patients with acute myeloid leukemia (AML), and 402 patients with high-risk myelodysplastic syndrome (MDS) were identified. GS occurred in 1.4% of patients with AML, and 1.1% of patients with AML or high-risk MDSs. The median patient age was 57 years (range, 7-81). Among 20 patients with available cytogenetics in tissue and/or bone marrow, six had chromosome 8 abnormalities. The median follow-up of surviving patients is 12 months (range, 7-75). In all, 20 patients were treated. Patients were treated with AML-type chemotherapy (n=16), chemotherapy and radiotherapy (n=3), or radiotherapy alone (n=1). A total of 13 patients (65%) achieved complete remission and one patient (5%) achieved partial remission. The median overall survival was 20 months (range, 1-75), median overall failure-free survival was 12 months (range, 1-75). The median survival of patients with chromosome 8 abnormalities was 12 months compared with 40 months of those without (P=0.17). Novel therapies for patients with GS are required.

Abstract
It has been unclear whether regimens containing topotecan + ara-C (TA) or fludarabine + ara-C (FA) +/- idarubicin are superior to regimens containing idarubicin + ara-C (IA) without either fludarabine or topotecan for treatment of newly diagnosed acute myeloid leukemia (AML), refractory anemia with excess blasts in transformation (RAEB-t), or RAEB. Of 1279 patients treated here for these diagnoses between 1991 and 1999, 322 received IA regimens, 600 FA regimens, and 357 TA regimens. All regimens used ara-C doses of 1 to 2 gm/m(2)/d, given by continuous infusion in IA, and over 2 to 4 hours in FA and TA. Complete remission (CR) rates were lower with FA (55%) and TA (59%) than with IA (77%). Both event-free survival (EFS) in CR and survival were shorter: median EFS in CR (95% confidence interval) was 63 weeks (range, 55-76 weeks) for IA, 40 (range, 31-46 weeks) for FA, and 36 (range, 27-44 weeks) for TA; median survival was 77 weeks (range, 57-88 weeks) for IA, 30 (range, 27-35 weeks) for FA, and 41 (range, 35-50 weeks) for TA. These trials were not randomized, and patients with worse prognoses were disproportionately given the FA and TA regimens. Nonetheless, after accounting for prognosis the FA and TA regimens remained highly significantly associated with lower CR rates, shorter EFS in CR, and shorter survival. Accounting for possible effects of individual trials within each of the IA, FA, and TA groups did not alter these findings. It is unlikely that, as given here, either FA or TA is, in general, superior to IA, highlighting the need for new treatments.

Abstract
Approximately 3 to 5% of patients with chronic lymphocytic leukemia (CLL) develop an aggressive large cell non Hodgkin's lymphoma (NHL) known as Richter's syndrome (RS). RS has a poor prognosis and a response rate of < 10% with fludarabine-based or other cytotoxic combination regimens. The aim of this study was to evaluate the efficacy and toxicity of the hyperCVXD regimen in RS. Twenty-nine patients, median age 61 years (36-75) 23 males, were treated. Prior diagnosis was CLL in 26 patients, NHL in 2, and Prolymphocytic leukemia in 1. Treatment consisted of fractionated cyclophosphamide, vincristine, daunoXome and dexamethasone. Six patients (20%) died while receiving study therapy, 4 (14%) during the first cycle of whom 2 had started therapy with overt pneumonia. Grade 4 granulocytopenia occurred in all 95 cycles of therapy with a median time to recovery of 14 days. Twenty three (24%) cycles were complicated by fever, and 15 (15%) by pneumonia. Sepsis was documented in 8 (8%) cycles, and neuropathy in 5 (5%) of cycles. Twenty three patients had a platelet count < 100 x 10(9)/l prior to therapy: a greater than 50% decrease in platelet count over pre-therapy level occurred in 79% of first cycles, overt bleeding occurred in 4 (4%) of all cycles. Eleven of 29 (38%) patients achieved complete remission (CR), 4 of whom have relapsed after 5, 6, 9, and 12 months of remission. Two of 11 CR patients presented with RS without any prior CLL therapy. One patient had a partial remission. Thus the overall response rate was 12/29 (41%). Overall median survival was 10 months, 19 months in patients who achieved CR, 3 months in those who did not (p = 0.0008). A landmark analysis performed at 2 months from start of therapy comparing patients alive in CR versus patients alive but not in CR showed a median survival of 19 months versus 6 months, respectively (p 0.0017). In conclusion the hyper CVXD regimen has a relatively high response rate, significant toxicity and a moderate impact on survival in RS.

Abstract
PURPOSE To investigate the toxicity profile, activity, and pharmacokinetics of a novel L-nucleoside analog, troxacitabine (BCH-4556), in patients with advanced leukemia. PATIENTS AND METHODS Patients with refractory or relapsed acute myeloid (AML) or lymphocytic (ALL) leukemia, myelodysplastic syndromes (MDS), or chronic myelogenous leukemia in blastic phase (CML-BP). Troxacitabine was given as an intravenous infusion over 30 minutes daily for 5 days. The starting dose was 0.72 mg/m(2)/d (3.6 mg/m(2)/course). Courses were given every 3 to 4 weeks according to toxicity and antileukemic efficacy. The dose was escalated by 50% until grade 2 toxicity was observed, and then by 30% to 35% until the dose-limiting toxicity (DLT) was defined. RESULTS Forty-two patients (AML: 31 patients; MDS: six patients [five MDS + one CMML]; ALL: four patients; CML-BP: one patient) were treated. Median age was 61 years (range, 23 to 79 years), and 29 patients were males. Stomatitis and hand-foot syndrome were the DLTs. The MTD was defined as 8 mg/m(2)/d. The pharmacokinetic behavior of troxacitabine is linear over the dose range of 0.72 to 10.0 m/m(2). Approximately 69% of troxacitabine was excreted as unchanged drug in the urine. Marrow hypoplasia occurred between days 14 and 28 in 73% of AML patients. Three complete remissions and one partial remission were observed in 30 assessable AML patients. One MDS patient achieved a hematologic improvement. A patient with CML-BP achieved a return to chronic phase disease. CONCLUSION Troxacitabine has a unique metabolic and pharmacokinetic profile and significant antileukemic activity. DLTs were stomatitis and hand-foot syndrome. Troxacitabine merits further study in hematologic malignancies.

Abstract
Daunorubicin and doxorubicin are anthracyclines that have efficacy against malignancies such as breast cancer, lung cancer, lymphoma, and leukemia. Their adverse effects are similar. The most serious is cardiotoxicity, which often limits the total cumulative dose that can be administered. Introduction of a liposomal formulation for both agents allows tumor selectivity by accumulating the drug in tumor tissue, thus increasing the tolerated dose. Liposomal doxorubicin is commonly associated with palmar-plantar erythrodysesthesia syndrome (PPES), although no reports of PPES were found in the literature related to liposomal daunorubicin (L-DNR). Two patients developed PPES while receiving high-dose L-DNR. The symptoms were self-limiting and resolved within a few weeks.

Abstract
Formation of an aberrant, chimeric Bcr-Abl protein is the hallmark of Philadelphia (Ph) chromosome-positive leukemias. The Bcr-Abl protein, as well as its normal cellular counterparts--Abl and Bcr--are intracellular molecules with postulated roles in a variety of critical biologic functions. In this study, we demonstrate the existence of autoantibodies against these proteins. Plasma from 18 of 31 individuals (58%), including 14 of 20 Ph-positive CML patients (70%), two of four normal volunteers (50%), and two of seven patients with Ph-negative leukemia (29%) recognized p210Bcr-Abl when used in immunoprecipitation followed by immunoblotting experiments. In all 18 patients, plasma was able to recognize baculovirus-expressed Abl protein; in four patients, recognition of baculovirus-expressed Bcr protein was also demonstrated. These observations suggest that a humoral immune response to p210Bcr-Abl is discernible in both Ph-positive and -negative leukemias and in healthy individuals, and is most likely due to autoantibodies which recognize normal Abl and, to a lesser extent, normal Bcr proteins.

Abstract
BACKGROUND Interleukin-2 (IL-2) has immunomodulatory effects, including stimulating the activity of cytotoxic T cells and natural killer cells, and inducing the generation of lymphokine-activated killer cells. The authors investigated whether IL-2 may improve the duration of complete remission (CR) and survival in acute myelogenous leukemia (AML) patients in first CR. METHODS Eighteen patients were included after achieving a CR and receiving at least two courses of consolidation chemotherapy. Therapy was comprised of IL-2 4.5 x 10(5) U/m2 daily by continuous infusion (CI) for 12 weeks, plus boluses of 1 x 10(6) U/m2 on Day 8 and weekly thereafter while continuing the CI. No further chemotherapy was given after the administration of IL-2 was started. RESULTS The median age of the patients was 50 years (range, 18-73 years), and 7 patients (39%) had an antecedent hematologic disorder (AHD). The median CR duration was 12 months, with 6 patients still alive in CR at a median follow-up of 64 months (range, 50-82 months). Long term CR by cytogenetics occurred in 2 of 5 patients with a normal karyotype (CR duration of 68+ months and 72+ months, respectively), 1 of 3 patients with t(8;21) (CR duration of 82+ months), 1 patient with inv(16) (CR duration of 67+ months), none of 2 patients with -5/-7 (1 patient died in CR after 10 months), 1 of 2 patients with abnormalities in chromosome 11 (CR duration of 60+ months), and 1 of 4 patients with miscellaneous abnormalities (CR duration of 74+ months). The median survival was 47 months. To assess the significance of these results, the authors selected two historic controls receiving long term postremission chemotherapy per each IL-2 case. The controls had remained in CR for at least as long as the cases when the latter underwent treatment initiation with IL-2 and were matched for the number of induction courses required to achieve CR, AHD, cytogenetic abnormalities, and age. Six of 18 IL-2 patients (33%) were alive in CR at 3 years compared with 7 of 36 controls (19%) (P = 0.31). Nine IL-2 patients (50%) were alive at 3 years compared with 10 controls (28%) (P = 0.13). CONCLUSIONS These results suggest that IL-2 is tolerable in AML patients in first CR and should be studied further in future studies as a therapeutic strategy to prolong remission duration.

Abstract
BACKGROUND T-cell lymphoid blastic phase (BP) transformation is rare in chronic myelogenous leukemia (CML). 2-amino-9-beta-D-arabinosyl-6-methoxy-9H-guanine (GW506U78), a prodrug of arabinosylguanine (ara-G), is effective in T-cell leukemias. METHODS The authors present a case of a 48-year-old male with Philadelphia chromosome (Ph) positive CML and T-cell lymphoid BP after 17 months in the chronic phase. RESULTS Plasma pharmacokinetic studies after an infusion of GW506U78 at a dose of 40 mg/kg showed GW506U78 concentrations of 60 microM, and a peak ara-G concentration of 260 microM in the plasma. Cellular ara-G triphosphate (ara-GTP) concentration in the peripheral blood T-lymphoblasts was 80 microM at the end of GW506U78 infusion and reached a maximum of 150 microM. The patient achieved a complete response that lasted 13 months. Severe neurotoxicity related to GW506U78 was observed. CONCLUSIONS GW506U78 showed antileukemic activity against Ph positive T-cell BP CML. Neurotoxicity was dose-limiting in this patient. Treatment with GW506U78 and modulation of ara-GTP concentrations are therapeutic strategies that require further exploration in T-cell malignancies. Investigation of other dosing schedules may limit neurotoxicity.

Abstract
BACKGROUND Patients with chronic myelogenous leukemia (CML) occasionally experience persistent thrombocythemia despite having adequate white blood cell (WBC) counts. Trimethylenethiophosphoramide (thiotepa) is an alkylating agent that significantly inhibits platelet production. METHODS The authors studied the effects of thiotepa in eight patients with CML with persistent thrombocythemia. All patients had adequate WBC counts while receiving therapy for leukemia. The median age of the patients was 58 years, and all had received at least 2 prior therapy regimens for CML. Thiotepa was administered by intravenous infusion at a dose of 75 mg/m2 once every 2 to 3 weeks; doses were adjusted according to hematologic response. RESULTS Seven patients were evaluable for response to thiotepa. Their pretreatment median platelet count was 1215 x 10(9)/L. After receiving the first dose, 6 patients (86%) had favorable responses as the median platelet count dropped to 348 x 10(9)/L (P = 0.02). However, all the patients' platelet counts returned to near baseline values after the first course. Patients required a median of three courses to achieve stable platelet counts near the normal range. In 4 patients (57%), administration of thiotepa was discontinued because of a stable normal platelet count after a median of 7.5 courses; 1 patient was still receiving treatment at last follow-up (18 courses) and 2 patients stopped receiving treatment after their disease progressed to the blastic phase. Toxicity was mostly hematologic, with neutropenia (< or = 1 x 10(9)/L) occurring during 5 of the 64 courses (8%) administered but only 1 patient's course was complicated by fever. CONCLUSIONS The authors conclude that thiotepa is useful in controlling thrombocythemia in CML patients who have elevated platelet counts despite having adequate WBC counts.

Abstract
Chronic myelogenous leukemia (CML) is a chronic myeloproliferative disorder with an initially chronic course lasting for 3-5 years. It eventually transforms into accelerated and blastic phases, which are generally fatal. CML was one of the first diseases in which a specific chromosomal abnormality was identified, a t(9;22)(q34;q11) or Philadelphia chromosome. CML had been traditionally treated with conventional chemotherapy with hydroxyurea or busulfan. Although these agents can achieve hematologic remissions in most patients, no evidence of sustained disappearance of the chromosomal abnormality was evident. Interferon alpha (IFN-alpha) has been able to achieve hematologic and cytogenic remissions in a significant number of patients, and recent studies show a survival advantage for patients treated with IFN-alpha compared with those treated with conventional chemotherapy. The results of these studies are discussed, and the reasons for discordance among different investigators analyzed in this review. Allogeneic bone marrow transplantation (BMT) may be curative in some patients with CML. The benefits and limitations of this approach in the treatment of CML are also discussed and the results of different alternatives compared. Other alternatives of therapy, including newer chemotherapeutic agents, combinations of IFN-alpha with other agents, and autologous BMT, are presented. The availability of very sensitive techniques for detection of the Philadelphia chromosome at the molecular level has allowed the detection of minimal residual disease. The information available on these measurements is also analyzed. Finally, we discuss the alternatives for patients with accelerated and blastic phase CML, as well as the clinical characteristics and prognosis for patients with Philadelphia-chromosome-negative CML.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. It is now curable in 60-70% of children. Most of the current understanding of the biology and treatment of ALL originates from studies of children. In adults, although much progress has been achieved, ALL is curable in only 20-35% of patients. METHODS A review of the biology and treatment of ALL from the English literature was performed. RESULTS Immunophenotypic and cytogenetic analyses of ALL have contributed to a more rational classification of ALL. These analyses have identified subgroups with poor prognosis or with different therapeutic requirements. Overall, 60-70% of adults with ALL have poor prognostic features, including older age, a high leukocyte count, non-T-cell immunophenotype, Ph-positive genotype, and longer time to achieve a complete remission. These patients have a cure rate of 20-25%, whereas those without these risk factors, have a 60-70% probability of survival. The use of more intensive induction regimens with growth factor support may improve survival rates. Also, intensive consolidation-intensification may improve survival rates. Most patients benefit from maintenance therapy, but the dose schedule must be optimized. Central nervous system (CNS) prophylaxis is beneficial, particularly for patients with a high risk for CNS relapse and when introduced early during induction of remission. Patients with high risk characteristics may benefit from allogeneic bone marrow transplantation (BMT) during first remission, and all other patients may benefit from it during first or subsequent relapse. Autologous BMT may be a valuable option for poor compliant patients. CONCLUSIONS Although the prognosis of patients with ALL has improved markedly during the past decades, newer strategies, including more dose-intensive therapy, the search for new drugs, and more target-specific therapy, are needed to improve the current cure rates.

Abstract
PURPOSE We reviewed the preclinical and clinical profiles of the antineoplastic taxoid docetaxel (Taxotere, Rhône-Poulenc Rorer, Collegeville, PA). DESIGN From the literature and manufacturer's data, we detail docetaxel's activity, tolerability, and pharmacokinetics in preclinical and phase I studies and its activity and side effects in phase II trials in various neoplasms. RESULTS Docetaxel promotes the assembly of and stabilizes microtubules, preventing their depolymerization. In phase I studies in patients with solid tumors refractory to standard chemotherapy, docetaxel's major dose-limiting toxicity (DLT) was dose- but not schedule-dependent neutropenia; another major side effect was schedule-dependent grade 3 mucositis. Other, generally less severe effects included hypersensitivity reactions (HSRs), neurotoxicities, cutaneous reactions, alopecia, and asthenia. Responses were observed in breast, bronchial, and ovarian carcinomas. The recommended dose for phase II studies was 100 mg/m2 as a 1-hour intravenous (i.v.) infusion every 3 weeks. Preliminary phase II results confirmed docetaxel's activity against breast, non-small-cell and small-cell lung, ovarian, head and neck, and gastric cancers; melanoma; and soft tissue sarcomas. Neutropenia again was the principal dose-limiting side effect. Nonhematologic effects, usually grade 1 or 2, including HSRs, were common. HSRs were manageable with premedication. Corticosteroid premedication partially alleviated fluid retention seen after repeated docetaxel courses. Studies are evaluating docetaxel in various combination regimens in advanced breast cancer, non-small-cell lung cancer, and other solid tumors. CONCLUSION Multicenter and single-institution studies have demonstrated docetaxel's consistent significant activity in various cancers. Phase III and combination therapy trials are ongoing. Work is in progress to understand and prevent/resolve some of this drug's side effects.

Abstract
Interleukin-10 (IL-10), also known as cytokine synthesis inhibitory factor, has multiple effects on lymphoid development. In addition, it has been previously reported that serum levels of IL-10 correlate with failure-free and overall survival in patients with non-Hodgkin's lymphoma. In this study, we used a sensitive enzyme-linked immunosorbent assay specific for human IL-10 (lower limit of sensitivity, 5 pg/mL) to measure serum levels in 52 newly diagnosed patients with diffuse large cell lymphoma and at least one adverse prognostic feature who were subsequently treated in a uniform way. Lymphoma patients had significantly higher serum levels of IL-10 (median, 7.98 pg/mL; range, < or = 5 to 27,143 pg/mL) than healthy volunteers (N = 50; median, < or = 5 pg/mL; range, < or = 5 to 19.21 pg/mL) (P = .0000012). Individuals with B symptoms had significantly higher serum levels of IL-10 than those without them (P = .03), but there was no correlation between IL-10 levels and any of the other prognostic variables analyzed, including age, lactic dehydrogenase, beta 2-microglobulin levels, performance status, bulky disease, Ann Arbor stage, or International Index score. More importantly, we found no correlation between IL-10 levels and the achievement of complete remission, nor with failure-free survival or overall survival. We conclude that in a uniform population of untreated patients with diffuse large cell lymphoma, serum levels of IL-10 do not appear to have any prognostic value.

Abstract
BACKGROUND Five to 10% of patients with chronic myelogenous leukemia (CML) do not have the Philadelphia chromosome (Ph), but one-third of them have rearrangements of the breakpoint cluster region (BCR-positive). METHODS The authors analyzed the characteristics, treatment response, and prognosis of 23 patients with BCR-positive, Ph-negative CML, and compared them with patients with Ph-positive CML, Ph-negative BCR-negative CML and chronic myelomonocytic leukemia (CMML) treated during the same period. RESULTS Seventeen patients had early chronic phase CML, 3 had late chronic phase, 2 had accelerated phase, and 1 had blastic phase. The median age was 44 years (range, 14-71 years), median platelet count was 402 x 10(9)/l, and median leukocyte count was 86 x 10(9)/l. Fourteen of the 17 patients with early chronic phase CML received alpha-interferon; 12 (86%) achieved complete hematologic remission. Median survival in chronic phase CML was 60 months (range, 3-90+ months). Patients with Ph-negative BCR-positive CML and those with Ph-positive CML had similar characteristics and outcome. Compared with patients with Ph-negative BCR-negative CML and CMML, patients with Ph-negative BCR-positive CML and Ph-positive CML were significantly younger, had a significantly higher incidence of leukocytosis, thrombocytosis, and peripheral and marrow basophilia, and a significantly lower incidence of anemia, thrombocytopenia, marrow blast percent, and peripheral and marrow monocytosis. The median survival was 60 months for Ph-negative BCR-positive CML, 73 months for Ph-positive CML, 25 months for Ph-negative BCR-negative CML, and 9 months for CMML (P < 0.001). When analyzed adjusting for their stage, patients classified with Ph-negative BCR-positive CML. Stage I disease had a significantly better survival than did patients with Ph-negative BCR-negative CML (P < 0.02). CONCLUSIONS Patients with Ph-negative BCR-positive CML are similar to those with Ph-positive CML and should be treated with the same approaches.

Abstract
Trisomy 21 is the second most common trisomy in patients with acute myelogenous leukemia (AML) and myelodysplastic syndromes (MDS). However, its clinical and prognostic significance is not known. We analyzed the records of 1187 consecutive patients with untreated AML or MDS. Thirty-seven (3.3%) had trisomy 21: four (0.3%) as the only cytogenetic abnormality and 33 (2.7%) with other cytogenetic abnormalities (-5 and/or -7 in 15, +8 in nine, t(15;17) in three, inv(16) in three, t(8;21) in one, and hyperdiploid with several other additional chromosomes in two). Twenty-eight patients had AML and nine MDS. No patients had megakaryocytic phenotype (M7), common in patients with constitutional trisomy 21 (Down's syndrome) and AML. Overall, 57% achieved complete remission (CR), with median CR duration of 39 weeks, and median survival of 31 weeks. When patients with additional cytogenetic abnormalities were compared to patients with similar abnormalities but no trisomy 21, their clinical features as well as their CR rate, CR duration and survival were similar, with or without trisomy 21. We conclude that trisomy 21 in AML typically presents in conjunction with other cytogenetic abnormalities, especially -5/-7 and +8 whose presence rather than the presence of +21 dictates the clinical outcome.

Abstract
BACKGROUND All-trans retinoic acid (ATRA) is effective in the treatment of relapsed or refractory acute promyelocytic leukemia (APL), but relapse is the rule if response is unmaintained. METHODS Seventeen patients with APL were salvaged with ATRA at a dosage of 50 mg/m2/day for 3 months or until complete remission (CR) was achieved; idarubicin (12 mg/m2/day for 4 days) was added if blast plus promyelocyte count either was or reached > or = 10 x 10(3)/microliters. After CR was achieved, patients received three courses of idarubicin (12 mg/m2 daily for 3 days) followed by three courses of mitoxantrone (5 mg/m2 daily for 3 days) and etoposide (250 mg/m2 daily for 3 days). Maintenance was with 6-mercaptopurine and methotrexate. RESULTS A CR was achieved in 14 patients (82%), the disease was refractory in 2 patients, and one patient died during induction. Three patients underwent allogeneic bone marrow transplant during CR. After a median follow-up of 26 weeks, six patients remain in CR. Median CR duration is 40 weeks (range 8-56+). Patients treated with ATRA plus chemotherapy in first salvage, when compared to a historic control group treated with chemotherapy alone, had a significantly better CR rate (87% vs. 57%; P = 0.04) and a lower induction death rate (7% vs. 29%; P = 0.08), resulting in longer median survival (26 vs. 17 weeks; P = 0.13). Four patients developed the "retinoic acid syndrome", which was fatal in one case. Three patients developed thrombotic events. CONCLUSIONS ATRA followed by chemotherapy is effective treatment for patients with APL who relapse after conventional therapy, and it may be superior to chemotherapy alone.

Abstract
The Ph chromosome, the abnormality characteristic of chronic myelogenous leukemia, was discovered in 1963. However, the events responsible for the pathogenesis and transformation to accelerated and blastic phases are still unknown at the molecular level and are subjects of ongoing research. The positive outcome in a subset of patients with interferon therapy and the potential for cure with bone marrow transplantation have evoked controversy regarding the best approach for different groups of patients according to prognostic characteristics. At the same time, new therapies with promising results are being developed, both in the setting of chemotherapy and biologic therapy and in bone marrow transplantation. Homoharringtonine chemotherapy, the use of matched unrelated donors for bone marrow transplantation, and new modalities of purging for autologous bone marrow transplantation are some examples. Sensitive molecular techniques that allow for the detection of small numbers of bcr-abl-positive hematopoietic cells may provide new means of assessing the results of current and future therapies.
