Abstract
The electronic health record (EHR) was adopted into the NorthShore University HealthSystem, a four-hospital integrated health system located in suburban Chicago, in 2003. By 2005, all chemotherapy and medicine order entry was conducted through the EHR, completing the incorporation of a fully paperless EHR in our hospital-based oncology practice in both the inpatient and outpatient settings. The use of the EHR has dramatically changed our practice environment by improving efficiency, patient safety, research productivity, and operations, while allowing evaluation of adherence to established quality measures and incorporation of new quality improvement initiatives. The reach of the EHR has been substantial and has influenced every aspect of care at our institution over the short period since its implementation. In this article, we describe subjective and objective measures, outcomes, and achievements of our 5-year EHR experience.

Abstract
Low CD34 + cell doses increase allograft-related mortality and very high doses increase the risk of graft-versus-host disease. The optimum CD34 + cell dose remains undefined. The effect of the CD34 + cell dose based on ideal weight was analyzed in 130 patients with hematologic malignancies undergoing reduced-intensity allogeneic blood cell transplantation in the context of factors known to affect the outcome: chemosensitivity, donor age, lactate dehydrogenase (LDH), human leukocyte antigen (HLA) match, performance status, and platelet count. The survival of patients receiving >8 x 10(6)/kg CD34 + cells was not significantly different from those receiving <6. The outcome of those receiving 6-8 x 10(6)/kg CD34 + cells was significantly better than the rest. This superiority was confirmed in multivariable analysis. Among patients receiving <or=8 x 10(6)/kg CD34 + cells, an increasing number of infused cells was associated with higher overall survival in a continuous fashion (Risk ratio (RR) 0.8759; p = 0.045). Cell dose based on actual weight did not correlate with survival. The number of CD34 + cells infused, a potentially modifiable factor, affects survival after reduced-intensity allogeneic transplantation. We recommend a CD34 + cell dose of 6-8 x 10(6) per kg ideal body weight to optimize outcome. The possible adverse effect of higher cell doses (>8) needs further confirmation.

Abstract
BACKGROUND The standard approach to treatment of relapsed/refractory Hodgkin's lymphoma (HL) is high-dose chemotherapy conditioning followed by autologous hematopoietic stem-cell transplantation (aHSCT). We report the results of a prospective phase I/II clinical trial of accelerated hyperfractionated total lymphoid irradiation (TLI) immediately followed by high-dose chemotherapy for relapsed/refractory HL. PATIENTS AND METHODS Forty-eight patients underwent aHSCT with either sequential TLI/chemotherapy (n = 32) or chemotherapy-alone conditioning (n = 16), based on prior radiation exposure. The first 22 patients enrolled on trial received escalating doses of etoposide (1600-2100 mg/m(2)) with high-dose carboplatin and cyclophosphamide. RESULTS No dose-limiting toxicity was seen and TLI/chemotherapy was well tolerated. The 5-year event-free survival (EFS) estimate for all patients was 44% with overall survival (OS) of 48%. Five-year EFS and OS for the TLI/chemotherapy group was 63% and 61%, respectively, compared with 6% and 27%, respectively, for the chemotherapy-alone group (P < 0.0001 and P = 0.04, respectively). Patients with primary induction failure HL who received TLI/chemotherapy had 5-year EFS and OS rate of 83%. The 100-day treatment-related mortality was 4.2% and two secondary cancers were seen. Significant factors predicting survival by multivariate analysis included TLI/chemotherapy conditioning and B symptoms at relapse. CONCLUSIONS Sequential TLI/chemotherapy conditioning for relapsed/refractory HL is safe and associated with excellent long-term survival rates.

Abstract
A 56-year-old woman diagnosed with a poorly differentiated cecal adenocarcinoma with metastases to ovaries, omentum, and sigmoid colon went into remission after 12 cycles of infusional 5-fluorouracil, luecovorin, and oxaliplatin (FOLFOX-4 regimen). Thirteen months later, a pelvic recurrence was diagnosed, and the patient received nine cycles of FOLFOX-6 plus bevacizumab, resulting in a clinical complete response but the development of pancytopenia. Bone marrow biopsy was consistent with therapy-related acute myelogenous leukemia. Chromosome analysis showed structural rearrangements with partial deletions of the long arms of chromosomes 5, 7, 20, and 21, as well as trisomy of chromosome 8 and losses of chromosomes 3 and 11. Induction chemotherapy led to remission, but the patient died two months later from complications of colon cancer progression. It is likely that the leukemia was related to the oxaliplatin administration.

Abstract
Sixty three patients aged 27-66 years (median 52) were allografted from HLA-matched sibling (n=47), 10 of 10 allele-matched unrelated (n=19), or one-antigen/allele-mismatched (n=7) donors aged 24-69 years (median 46) after a conditioning regimen comprising 100 mg/m(2) melphalan. Cyclophosphamide (50 mg/kg) was also administered to patients who had not been autografted previously. Cyclosporine or tacrolimus, and mycophenolate mofetil were administered to prevent graft-versus-host disease (GVHD). The 2-year cumulative incidences of relapse and TRM were 55 and 24% respectively, and 2-year probabilities of overall survival (OS) and disease-free survival (DFS) were 36 and 21%, respectively. Poor performance status, donor age >45 years and elevated lactate dehydrogenase (LDH) increased the risk of treatment-related mortality (TRM), refractory disease and donor age >45 years increased the risk of relapse, and OS and DFS were adversely influenced by refractory disease, poor performance status, increased LDH, and donor age >45 years. Our data suggest that younger donor age is associated with better outcome after sub-myeloablative allogeneic hematopoietic stem cell transplantation (HSCT) for hematologic malignancies due to lower TRM and relapse. This finding raises the question of whether a young 10-allele-matched unrelated donor is superior to an older matched sibling donor in patients where the clinical situation permits a choice between such donors.

Abstract
We previously reported a phase 2 trial of 69 patients with newly diagnosed anaplastic or aggressive oligodendroglioma who were treated with intensive procarbazine, CCNU (lomustine), and vincristine (PCV) followed by high-dose thiotepa with autologous stem cell rescue. This report summarizes the long-term follow-up of the cohort of 39 patients who received high-dose thiotepa with autologous stem cell support. Thirty-nine patients with a median age of 43 (range, 18-67) and a median KPS of 100 (range, 70-100) were treated. Surviving patients now have a median follow-up of 80.5 months (range, 44-142). The median progression-free survival is 78 months, and median overall survival has not been reached. Eighteen patients (46%) have relapsed. Neither histology nor prior low-grade oligodendroglioma correlated with risk of relapse. Persistent nonenhancing tumor at transplant was identified in our initial report as a significant risk factor for relapse; however, long-term follow-up has not confirmed this finding. Long-term neurotoxicity has developed only in those patients whose disease relapsed and required additional therapy; no patient in continuous remission has developed a delayed neurologic injury. This treatment strategy affords long-term disease control to a subset of patients with newly diagnosed anaplastic oligodendroglioma without evidence of delayed neurotoxicity or myelodysplasia.

Abstract
Whether the CD34+ and CD3+ cell doses in allogeneic HSCT should be estimated using actual (ABW) or ideal (IBW) body weight has never been definitively determined. We have shown that CD34+ cell doses based upon IBW are better predictive of engraftment after autologous and allogeneic HSCT. Sixty-three patients undergoing reduced-intensity HSCT after a uniform preparative regimen were evaluated to determine the effect of cell dose. ABW and IBW were 45-147 kg (median 79) and 52-85 kg (median 67) respectively. The ABW-IBW difference was -24% to +133% (median +16%); nine patients were >5% underweight and 41 were >5% overweight. The CD34+ cell dose (10(6)/kg) was 1.4-11.8 (median 5) by IBW and 1.2-9.3 (median 4.5) by ABW. The CD3+ cell dose (10(8)/kg) was 0.9-14.9 (median 3) by IBW and 0.7-19.7 (median 2.7) by ABW. While CD34+ and CD3+ cell doses based upon IBW were found to affect transplant-related mortality, and disease-free and overall survival significantly, those based on ABW were either not predictive of outcome or the differences were of borderline significance. We suggest using IBW rather than ABW to calculate cell doses for HSCT; for statistical analyses and for clinical practice if a specific cell dose is being targeted.

Abstract
PURPOSE Anaplastic oligodendroglioma is a chemosensitive glial neoplasm. To improve disease control and postpone cranial radiotherapy, we designed a phase II study of intensive procarbazine, lomunstine and vincristine followed by high-dose thiotepa with autologous stem cell rescue for patients with newly diagnosed anaplastic or aggressive oligodendroglioma. PATIENTS AND METHODS Sixty-nine patients with a median age of 42 (range: 18-67) and a median Karnofsky Performance Score of 90 (range: 70-100) were enrolled. Sixteen patients had a prior diagnosis of low-grade oligodendroglioma and 16 had mixed oligoastrocytoma pathology. Only patients with demonstrably chemosensitive enhancing tumors or those free of enhancing tumor after surgery and induction therapy were eligible to receive high-dose thiotepa. RESULTS Thirty-nine patients (57%) completed the transplant regimen; their estimated median progression-free survival is 69 months and median overall survival has not been reached. Twelve transplanted patients (31%) relapsed. Neither histology nor prior low-grade oligodendroglioma correlated with relapse; however, persistent non-enhancing tumor at transplant conferred an increased risk of relapse (p = 0.028). The transplant regimen was well-tolerated; median hospital stay was 20 days (range: 7-43) with a median time to ANC and platelet engraftment of 10 days. Thirty patients (43%) did not receive high-dose thiotepa because of stable or progressive disease (n = 21), excessive toxicity (n = 4), refusal of further therapy (n = 2), failure to obtain insurance coverage (n = 2), or other (n = 1). No treatment-related or long-term neurotoxicity was seen in the transplanted patients. CONCLUSIONS High-dose chemotherapy with stem cell rescue as initial treatment for anaplastic oligodendroglioma is feasible and associated with prolonged tumor control in some patients.

Abstract
The objective of this study was to ascertain the duration of tumor control and the toxicities of dose-intense myeloablative chemotherapy for patients with recurrent oligodendrogliomas. Patients with previously irradiated oligodendrogliomas, either pure or mixed, that were contrast enhancing, measurable, and behaving aggressively at recurrence were eligible for this study. Only complete responders or major partial responders (75 % reduction in tumor size) to induction chemotherapy--either intensive-dose procarbazine, lomustine, and vincristine or cisplatin plus etoposide-could receive high-dose thiotepa (300 mg/m2/day for 3 days) followed by hematopoietic reconstitution using either bone marrow or peripheral blood stem cells. Thirty-eight patients began induction chemotherapy and 20 (10 men, 10 women; median age 46 years; median Karnofsky score 80) received high-dose thiotepa. For the high-dose group, the median event-free, progression-free, and overall survival times from recurrence were 17, 20, and 49 months, respectively. Tumor control in excess of 2 years was observed in 6 patients (30%). Four patients (20%) are alive and tumor free 27 to 77 months (median, 42 months) from the start of induction therapy; however, fatal treatment-related toxicities also occurred in 4 patients (20%). Three patients died as a result of a progressive encephalopathy which, in 2 instances, was accompanied by a wasting syndrome; 1 patient died as a consequence of an intracerebral (intratumoral) hemorrhage. Fatal toxicities occurred in patients with pretreatment Karnofsky scores of 60 or 70. High-dose thiotepa to consolidate response was a disappointing treatment strategy for patients with recurrent aggressive oligodendroglial neoplasms, although several patients had durable responses. Moreover, as prescribed, high-dose thiotepa had significant toxic effects in previously irradiated patients, especially those with poorer performance status.

Abstract
PURPOSE Considerable morbidity and mortality and costs occur during induction therapy for acute myeloid leukemia (AML). Colony-stimulating factors (CSFs) can shorten neutropenia, and may lower costs. We performed a cost-minimization analysis of granulocyte macrophage colony stimulating factor (GM-CSF) for AML patients > 55 to 70 years of age during an Eastern Cooperative Oncology Group Study. PATIENTS AND METHODS Clinical data were from a randomized double-blind phase III trial of 117 AML patients. Estimates of costs were from financial accounts from seven participating institutions. Costs were reported from the third party payor perspective. Analyses were conducted utilizing a decision analytic model. The primary source of event probabilities was in-hospital care with or without an active infection. Sensitivity analyses were also reported. RESULTS When compared to AML patients who received placebo. GM-CSF patients had fewer grade 4-5 infections (9.6% versus 36.2%, P = 0.002) and grade 3-5 infections (52% versus 70%. P = 0.07) and $2.310 in savings. Sensitivity analyses indicated that similar cost estimates applied over a range of clinical and economic assumptions. CONCLUSIONS This analysis can serve as a template for cooperative group cost analyses. Cooperation on study methodologies may allow for results that are relevant to both clinicians and policy makers.

Abstract
Twenty patients with disseminated cancer both untreated and previously treated received bialkylator chemotherapy, thiotepa, and cyclophosphamide and reinfusion of cryopreserved autologous bone marrow (ABMR). The cyclophosphamide dose was constant at 7.5 g/m2 over three days, while thiotepa was started at 1.8 mg/kg for three days in escalating dose by a modified Fibonacci schema to 7 mg/kg. The median time to recovery of more than 500 granulocytes and more than 50,000 platelets/microL was 18 and 27 days, respectively. Four patients died as a consequence of severe, overwhelming infections or progressive disease during their period of aplasia. Of the 18 evaluable patients, a complete response (CR) was achieved in three patients and a partial response (PR) in ten patients for an overall response rate of 72%. The median duration of response was 14 weeks. Other nonhematologic toxicities included nausea/vomiting, diarrhea, stomatitis, skin rash, and cardiomyopathy. The maximum tolerated dose (MTD) of thiotepa was 700 mg/m2 or 6 mg/kg for three doses. Although there are substantial toxicities associated with this regimen, high-dose thiotepa and cyclophosphamide produce high response rates in patients with disseminated cancer.
