Autologous transplantation followed closely by reduced-intensity allogeneic transplantation as consolidative immunotherapy in advanced lymphoma patients: a feasibility study.

We report outcomes in advanced lymphoma patients (n = 32) who enrolled in a trial of prospectively planned combined autologous/reduced-intensity transplantation (RIT) (n = 25) or who received RIT shortly after prior autografting because of high relapse risk or progressive disease (n = 7). Nine patients on the autologous/RIT transplant protocol did not proceed to planned RIT because of patient choice (n = 4), disease progression (n = 3), toxicity (n = 1), or no adequate donor (n = 1). Among the 23 other patients, RIT was started a median of 59 days (range 31-123) after autologous transplant. Fifteen patients had related donors, five patients had unrelated donors, and three patients had cord blood donors. Among all patients completing RIT, the median overall survival time was 385 days (95% CI 272-792), and the median relapse-free survival time was 157 days (95% CI 119-385). At the time of reporting, six patients (26%) remain alive and three patients (13%) remain alive without relapse. The 100-day transplant-related mortality (TRM) was 9% among all patients and was 0% among matched sibling donors. Overall TRM was 43%. Tandem transplant is feasible in advanced lymphoma with low early TRM. However, practical challenges associated with the strategy were significant and high levels of late TRM due to graft-versus-host disease and infections suggest that modifications of the procedure will be needed to improve outcomes and patient retention.

Nonmyeloablative allogeneic hematopoietic stem cell transplantation for congenital sideroblastic anemia.

Congenital sideroblastic anemia (CSA) is a dyserythropoietic disorder that leads to transfusion dependency and subsequent iron overload. Nonmyeloablative allogeneic hematopoietic stem cell transplantation (NST) was performed for a patient with CSA, who had contraindications to conventional allografting. Conditioning was fludarabine, low-dose total body irradiation and antithymocyte globulin, followed by peripheral blood stem cell transplant. Cyclosporine and mycophenolate mofetil were used for graft-versus-host disease prophylaxis. Complete donor chimerism was observed day +131. Early after transplant, the patient became transfusion independent, allowing a regular phlebotomy program. On day +190, refractory lactic acidosis followed by fatal cardiovascular collapse developed, without evidence of infection. Data from this case demonstrates that NST may correct the erythropoietic defect of CSA.

Avoiding hepatic veno-occlusive disease: what do we know and where are we going?

Hepatic venocclusive disease (VOD) is a common toxicity associated with myeloablative chemotherapy or chemoradiotherapy used to prepare patients for stem cell transplantation. A sizable proportion of patients who develop VOD die. It is clear that injury to endothelial cells and hepatocytes in zone 3 of the liver acinus is the initial event in the pathogenesis of VOD. What are less clear are the mechanisms of injury and whether this knowledge can be exploited. This manuscript will briefly review some recent data and discuss how that information has influenced clinical practice.

Body-image and eating disturbances prospectively predict increases in depressive symptoms in adolescent girls: a growth curve analysis.

Using data from a longitudinal community study (N = 231), the authors tested whether body-image and eating disturbances might partially explain the increase in depression observed in adolescent girls. Initial pressure to be thin, thin-ideal internalization, body dissatisfaction, dieting, and bulimic symptoms, but not body mass, predicted subsequent increases in depressive symptoms, as did increases in these risk factors over the study. There was also prospective support for each of the hypothesized mediational relations linking these risk factors to increases in depressive symptoms. Effects remained significant when other established gender-nonspecific risk factors for depression (social support and emotionality) were statistically controlled. Results provide support for the assertion that body-image and eating disturbances, operating above and beyond gender-nonspecific risk factors, contribute to the elevated depression in adolescent girls.

Relation of early menarche to depression, eating disorders, substance abuse, and comorbid psychopathology among adolescent girls.

This prospective study tested whether early menarche partially accounts for the increases in depression, eating pathology, substance abuse, and comorbid psychopathology that occur among adolescent girls, with structured interview data from a community sample (N = 496). Early menarche (prior to 11.6 years) was associated with elevated depression, substance abuse, and "any" disorder but did not confer increased risk for anorexia nervosa, bulimia nervosa, or binge eating disorder. Although there was significant comorbidity across all three classes of pathology, early menarche was associated only with comorbid depression and substance abuse. Results provide partial support for the assertion that early menarche is a general risk factor for psychopathology among adolescent girls but suggest that this risk may not apply to certain disorders and that the effects are modest in size.

Efficacy of a mixed amphetamine salts compound in adults with attention-deficit/hyperactivity disorder.

BACKGROUND: We report on a controlled trial of a mixed amphetamine salts compound (Adderall, dextroamphetamine sulfate, dextro-, levoamphetamine sulfate, dextroamphetamine aspartate, levoamphetamine aspartate, and dextroamphetamine saccharate) in the treatment of adult attention-deficit/hyperactivity disorder (ADHD). METHODS: This was a 7-week, randomized, double-blind, placebo-controlled, crossover study of Adderall in 27 well-characterized adults satisfying full DSM-IV criteria for ADHD of childhood onset and persistent symptoms into adulthood. Medication was titrated up to 30 mg twice a day. Outcome measures included the ADHD Rating Scale and the Clinical Global Impression Score. Comorbid psychiatric disorders were assessed to test for potential effects on treatment outcome. RESULTS: Treatment with Adderall at an average oral dose of 54 mg (administered in 2 daily doses) was effective and well tolerated. Drug-specific improvement in ADHD symptoms was highly significant overall (42% decrease on the ADHD Rating Scale, P<.001), and sufficiently robust to be detectable in a parallel groups comparison restricted to the first 3 weeks of the protocol (P<.001). The percentage of subjects who improved (reduction in the ADHD rating scale of > or =30%) was significantly higher with Adderall treatment than with a placebo (70% vs 7%; P =.001). CONCLUSIONS: Adderall was effective and well tolerated in the short-term treatment of adults with ADHD. More work is needed to evaluate the long-term effects of Adderall, or other amphetamine compounds, in the treatment of adults with ADHD.

Impact of tic disorders on ADHD outcome across the life cycle: findings from a large group of adults with and without ADHD.

OBJECTIVE: The impact of tic disorders on the outcome of attention deficit hyperactivity disorder (ADHD) remains a subject of high scientific and clinical interest. To evaluate the impact of comorbid ADHD and tic disorders from a lifespan perspective, the authors systematically examined data from adults with and without ADHD. METHOD: They comprehensively evaluated 312 consecutively referred adults with ADHD and 252 comparison subjects without ADHD. Tic disorders were characterized along with a wide range of neuropsychiatric correlates, including other comorbid disorders as well as indexes of function in the domains of school, cognition, and interpersonal functioning. RESULTS: A significantly greater proportion of adults with ADHD (12%) than those without ADHD (4%) had tic disorders. Tic disorders followed a mostly remitting course and had little impact on functional capacities. In addition, tic disorders were not associated with stimulant use. CONCLUSIONS: These findings in adults with ADHD confirm and extend previous findings in young subjects with ADHD, documenting that although individuals with ADHD are at greater risk for tic disorders, the presence of tic disorders has a limited impact on ADHD outcome.

Nephrectomy followed by interferon alfa-2b compared with interferon alfa-2b alone for metastatic renal-cell cancer.

BACKGROUND: The value of nephrectomy in metastatic renal-cell cancer has long been debated. Several nonrandomized studies suggest a higher rate of response to systemic therapy and longer survival in patients who have undergone nephrectomy. METHODS: We randomly assigned patients with metastatic renal-cell cancer who were acceptable candidates for nephrectomy to undergo radical nephrectomy followed by therapy with interferon alfa-2b or to receive interferon alfa-2b therapy alone. The primary end point was survival, and the secondary end point was a response of the tumor to treatment. RESULTS: The median survival of 120 eligible patients assigned to surgery followed by interferon was 11.1 months, and among the 121 eligible patients assigned to interferon alone it was 8.1 months (P=0.05). The difference in median survival between the two groups was independent of performance status, metastatic site, and the presence or absence of a measurable metastatic lesion. CONCLUSIONS: Nephrectomy followed by interferon therapy results in longer survival among patients with metastatic renal-cell cancer than does interferon therapy alone.

Intensive chemotherapy for progressive chronic lymphocytic leukemia administered early after a nonmyeloablative allograft.

A 51-year-old patient with refractory CLL elected to participate in a trial of nonmyeloablative trans- plantation from an HLA-matched unrelated donor. He received low-dose fludarabine/TBI, with infusion of donor PBPC and cyclosporin (CsA)/MMF. Early post transplant he experienced explosive tumor growth with respiratory insufficiency. After immunosuppression discontinuation and rituximab administration, no response was observed. This prompted treatment with cyclophosphamide (2 g/m(2)/day x 2), paclitaxel (250 mg/m(2) over 24 h), doxorubicin (50 mg/m(2)), solumedrol (500 mg/day), and a second dose of rituximab, from days +11 to +14. A rapid response was achieved. Chemotherapy did not cause an obvious compromise of donor stem cell engraftment or establishment of stable donor chimerism.

Status of high-dose chemotherapy for breast cancer: a review.

The purpose of this review is to analyze the current status of high-dose chemotherapy (HDCT) with autologous stem cell transplantation for patients with breast cancer. Current results from the major prospective phase 2 and phase 3 trials in metastatic breast cancer (MBC) and high-risk primary breast cancer (HRPBC) are reviewed. Prognostic factors and future research directions are also discussed. The encouraging results of phase 2 trials suggested a benefit for HDCT in HRPBC and some categories of patients with MBC. Some investigators have argued that patient selection might have been a critical factor in those studies. Recently reported randomized trials in patients with chemosensitive MBC have included only small numbers of patients in complete remission and thus have not adequately addressed the relative value of HDCT versus maintenance standard-dose chemotherapy in this patient subset. Although initial results of 2 studies have been reported, most randomized phase 3 studies of HDCT in HRPBC require longer follow-up before definitive conclusions can be made about its efficacy in this setting. We conclude that the role of HDCT for HRPBC or MBC patients has not yet been fully defined. Longer follow-up of the ongoing randomized trials is necessary, and their mature results will help clarify this important question. In the meantime, it is imperative that research continues, to enhance the efficacy of the procedure. This may come through incorporating more active drugs into HDCT regimens and combining HDCT with novel strategies aimed at eradication of posttransplantation minimal residual disease.

Ex vivo expanded peripheral blood progenitor cells provide rapid neutrophil recovery after high-dose chemotherapy in patients with breast cancer.

Ex vivo expanded peripheral blood progenitor cells (PBPCs) have been proposed as a source of hematopoietic support to decrease or eliminate the period of neutropenia after high-dose chemotherapy. CD34 cells were selected from rhG-CSF mobilized PBPCs from patients with breast cancer and were cultured for 10 days in defined media containing 100 ng/mL each of rhSCF, rhG-CSF, and PEG-rhMGDF in 1 L Teflon bags at 20 000 cells/mL. After culture the cells were washed and reinfused on day 0 of transplantation. On day +1, cohort 1 patients (n = 10) also received an unexpanded CD34-selected PBPC product. These patients engrafted neutrophils (absolute neutrophil count, >500/microL) in a median of 6 (range, 5-14) days. Cohort 2 patients (n = 11), who received expanded PBPCs only, engrafted neutrophils in a median of 8 (range, 4-16) days. In comparison, the median time to neutrophil engraftment in a historical control group of patients (n = 100) was 9 days (range, 7-30 days). All surviving patients are now past the 15-month posttransplantation stage with no evidence of late graft failure. The total number of nucleated cells harvested after expansion culture was shown to be the best predictor of time to neutrophil engraftment, with all patients receiving more than 4 x 10(7) cells/kg, engrafting neutrophils by day 8. No significant effect on platelet recovery was observed in any patient. These data demonstrate that PBPCs expanded under the conditions defined can shorten the time to engraftment of neutrophils compared with historical controls and that the rate of engraftment is related to the dose of expanded cells transplanted.

Acute pancreatitis during immunosuppression with tacrolimus following an allogeneic umbilical cord blood transplantation.

Tacrolimus is increasingly used for graft-versus-host disease (GVHD) prophylaxis and therapy in the allogeneic stem cell transplant (allo-SCT) setting. Pancreatitis, previously described as a side-effect of cyclosporine, has not been reported in allo-SCT recipients receiving tacrolimus. We present here a case of acute pancreatitis in a 28-year-old patient with chronic myelogenous leukemia (CML) who received an unrelated umbilical cord blood transplant (UCBT) and tacrolimus for GVHD prophylaxis. On day +31 post-transplant, she developed severe acute pancreatitis with multiorgan failure, from which she recovered completely. Tacrolimus was the probable cause of pancreatitis in this patient.

Evaluation of the predictive value of Her-2/neu overexpression and p53 mutations in high-risk primary breast cancer patients treated with high-dose chemotherapy and autologous stem-cell transplantation.

PURPOSE: To ascertain the predictive value of Her-2/neu overexpression and p53 mutations, assessed by immunohistochemistry, in high-risk primary breast cancer (HRPBC) treated with high-dose chemotherapy (HDCT). PATIENTS AND METHODS: We obtained paraffin-embedded tumor blocks from 146 HRPBC patients previously enrolled at our program onto clinical trials of HDCT for four to nine involved axillary lymph nodes, > or = 10 involved axillary nodes, or inflammatory carcinoma. All patients received the same HDCT regimen, with cyclophosphamide, cisplatin, and carmustine (STAMP-I), followed by autologous stem-cell transplantation. Median follow-up was 42 months (range, 5 to 90 months). The same pathologist, blinded to clinical outcome, reviewed all immunostained slides. RESULTS: Positive results for Her-2/neu and p53 were found in 44.5% and 34% of the patients, respectively. Positivity for Her-2/neu was significantly associated with increased risk of relapse and death. No correlation was found between p53 mutations and relapse-free survival (RFS) or overall survival (OS). Multivariate analyses included Her-2/neu overexpression and the following variables previously identified as independent predictors of outcome in this population: tumor size, nodal ratio (number of involved nodes/number of dissected nodes), and hormone receptor status. All four variables had independent value. CONCLUSION: Her-2/neu overexpression is an independent negative predictor of RFS and OS in HRPBC treated with HDCT. Its inclusion in our previously described predictive model increases the predictive capacity of this model for the low-risk subgroup. In contrast, p53 mutations lack predictive value in this setting.

Cardiac toxicity following high-dose cyclophosphamide, cisplatin, and BCNU (STAMP-I) for breast cancer.

We retrospectively evaluated 443 breast cancer patients treated with high-dose cyclophosphamide, cisplatin, and BCNU (STAMP-I) with autologous stem cell support to characterize the cardiac toxicity of this regimen. Patients had stage II-III (n = 243) or stage IV (n = 200) breast cancer. We observed an overall 5.1% incidence of cardiac complications, both clinical and subclinical, in the whole group: 4.9% in stage II-III and 5.5% in stage IV patients. Clinical cardiomyopathy (CMP) was observed in 1.6% of stage II-III patients (1 case of fatal grade 5 toxicity and 3 cases of grade 3 CMP) and in 3.5% of patients with stage IV disease (1 case of grade 4 and 6 cases of grade 3). The incidence of cardiac toxicity did not differ significantly between the groups. Prior radiation therapy to the mediastinum or left chest wall (P = .001) and advanced age (P = .01) were independent predictors of an increased risk of the appearance of this complication. No pharmacodynamic correlation was observed between any of the 3 drugs and cardiac toxicity.

Veno-occlusive disease of the liver.

The success of high-dose cytoreductive strategies depends not only on antitumor activity but also on the tolerability of treatment. Although advances in supportive care have significantly reduced mortality due to infection and hemorrhage, regimen-related toxicities remain problematic. Hepatic veno-occlusive disease (VOD) is the most serious regimen-related toxicity after high-dose cytoreductive therapy. Risk factors for VOD are well established, but the biology of the syndrome remains poorly understood. Unfortunately, no pharmacologic approaches that clearly prevent or treat VOD have been identified. A better understanding of the pathogenesis of VOD will lead to more effective prevention and treatment strategies.

Graft-versus-leukemia-induced complete remission following unrelated umbilical cord blood transplantation for acute leukemia.

A 15-year-old female received an unrelated three of six HLA antigen matched umbilical cord blood (UCB) transplant for refractory, relapsed T-cell ALL. Conditioning consisted of TBI, melphalan, and anti-thymocyte globulin (ATG), with cyclosporin A (CsA) and solumedrol for GVHD prophylaxis. She engrafted and a day 34 bone marrow aspirate showed 100% donor cells and no evidence of leukemia. The post-transplant course was complicated by mild grade I acute GVHD involving skin, and limited chronic GVHD of the gut which resolved with the addition of 1 mg/kg/day of steroids to her CsA prophylaxis. One hundred and ninety days after transplantation the patient developed pancytopenia and was subsequently found to have a leukemic relapse. Immunosuppression was discontinued and she was started on G-CSF and erythropoietin. Moderate skin and gut GVHD developed which was treated with both topical and low-dose oral steroids. Over the next few weeks she became transfusion independent and a follow-up bone marrow aspirate showed complete remission. She continued in complete remission for 4 months, at which time localized leukemic relapse was found in a soft tissue breast mass in spite of continued bone marrow remission. While the patient ultimately died of progressive disease, this case demonstrates that mismatched UCB in conjunction with G-CSF is capable of generating a GVL effect that can induce a complete remission.

A predictive model for relapse in high-risk primary breast cancer patients treated with high-dose chemotherapy and autologous stem-cell transplant.

High-dose chemotherapy (HDCT) is currently under evaluation for high-risk primary breast cancer (HRPBC), defined by extensive axillary nodal involvement or inflammatory breast carcinoma. Phase II studies of HDCT for HRPBC show that 30-40% of patients eventually relapse. We retrospectively reviewed 176 patients enrolled in clinical trials of HDCT for HRPBC at the University of Colorado and analyzed 23 potential predictive variables for relapse. All of the patients received the same regimen, with cyclophosphamide, cisplatin, and BCNU. Nine patients who experienced a toxic death were excluded from this analysis. The resulting predictive model was subsequently tested in an independent patient set treated at Duke University with the same HDCT regimen. Nodal ratio (number of involved nodes:number of sampled nodes), tumor size, grade, stage, estrogen receptor, progesterone receptor, and clinical inflammatory breast carcinoma correlated with risk of relapse. Nodal ratio, tumor size, and the combined estrogen receptor/progesterone receptor status were independent predictors. A scoring system using those three variables determines the risk of relapse, with a sensitivity and specificity of 60 and 90%, respectively, and a positive and negative predictive value of 65 and 88%, respectively. The differences in relapse-free survival and overall survival between high- and low-score patients were highly significant (P<0.000001). This model was subsequently validated in the Duke patient set. This model can identify two subgroups of HRPBC patients with low (12%) and high (65%) risk for recurrence after HDCT. Future research that tests new therapies will focus on those patients with a high score.

Optic disc and retinal microvasculopathy after high-dose chemotherapy and autologous hematopoietic progenitor cell support.

The purpose of this study was to prospectively evaluate the retinal and optic nerve changes in patients undergoing high-dose chemotherapy (HDC) followed by autologous hematopoietic progenitor cell support (AHPCS). One hundred and forty patients undergoing HDC and AHPCS underwent extensive pre- and post-transplant ophthalmologic evaluations for development of retinal microvascular complications. One hundred and ten patients received high-dose cyclophosphamide, cisplatin and BCNU; thirty received identical doses of cyclophosphamide and cisplatin, but received paclitaxel instead of BCNU. Thirty-four patients (24%) had retinal findings of either cotton wool spots (CWS) (n = 20) or retinal hemorrhages (n = 18) during follow-up, which ranged from 1 to 12 months. Ten (7%) of these patients, all of whom received BCNU, showed ocular toxicity characterized by CWS 1 to 4 months post transplant (n = 10); optic disc edema (n = 3); and variable vision loss associated with the onset of BCNU-induced pulmonary toxicity. Retinal and optic disc microvascular complications may occur after high-dose chemotherapy followed by AHPCS. The association of ischemic retinal lesions and/or optic disc edema with BCNU-induced pulmonary toxicity and the lack of ocular toxicity in patients that did not receive BCNU may suggest that BCNU is the etiologic agent.
