Abstract
7097 Background: We present preliminary data of haploidentical transplant for 13 patients (pts) with acute leukemia. Methods: Phase II Study Results: We present preliminary data of haploidentical transplant for 13 patients (pts) with acute leukemia using a chemotherapy-only preparative regimen of Melphalan 140 mg/m2 on day −8; Thiotepa 10 mg/kg on day −7; Fludarabine 40 mg/m2 on days −6, −5, −4, −3; 1.5 mg/kg of rabbit ATG/day days −6, −5, −4, −3. The transplant was administered on day 0 using positive selection of CD34 positive cells by the CliniMACS device as a means of T-cell depletion. All products had <1 × 104 CD3+ T-cells/kg recipient body weight and needed a minimum of 5 × 106 CD34+ cells/kg but preferably >1 × 107 CD34+ cells/kg recipient body weight. Age ranged 23–50 years/median 37 years, four patients were in advanced remission and nine were in refractory relapse. Patients received intensive PCP prophylaxis with sulfamethoxazole-trimethoprim and pentamidine prior to transplant and during pancytopenia; CMV prophylaxis with valganciclovir during the BMT prep and foscarnet while pancytopenic; and with liposomal amphotericin or cancidas for fungal prophylaxis. Two patients had primary graft failure-one survived disease free and one relapsed. One patient died of multiple organ failure prior to engraftment. Median time to engraftment was 15 days (range, 9–26) to 500 neutrophils and 14 days to platelets 20,000 (range, 13–25). Seven patients died of relapse at a median of 10 months (range 2–13 months), and one patient died of a viral infection. Two of 10 patients who engrafted developed grade one acute graft-versus-host (GVHD) and four patients had chronic GVHD (3 limited, 1 extensive). Four patients survive beyond 2 years, without recurrent disease. Conclusions: This report for haploidentical transplant demonstrates that a chemotherapy only preparative regimen can achieve a high rate of engraftment. Infectious complications were minimal with aggressive prophylaxis. Long-term remission are achievable with little risk of severe GVHD with t-cell depletion with use of CliniMACS in haploidentical stem cell transplant. No significant financial relationships to disclose.

Abstract
We explored the safety and efficacy of rituximab administered in combination with the standard transplant conditioning regimen of cyclophosphamide (Cy) 120 mg/kg and total body irradiation (TBI) 12 Gy for adult patients with acute lymphoblastic leukemia (ALL). Patients were eligible if their disease expressed CD20. Rituximab was administered at 375 mg/m2 weekly for four doses beginning on day -7 of the conditioning regimen. Graft-versus-host-disease (GVHD) prophylaxis consisted of tacrolimus and methotrexate. Thirty-five patients undergoing matched sibling (n = 23) or unrelated donor (n = 12) transplantation were studied, with a median age of 30 years (range 15-55 years). At 2 years, progression-free survival, treatment-related mortality, and overall survival were 30, 24, and 47%, respectively. There was no delay in engraftment or increased incidence of infection. The cumulative incidence of grade II-IV acute GVHD was 17%, and limited and extensive chronic GVHD was 43% at 2 years. The addition of rituximab to the standard Cy/TBI transplant conditioning regimen in ALL was safe and well tolerated, and there was a suggestion of decreased incidence of acute GVHD when compared to historically reported GVHD rates for this group of patients.

Abstract
The role of high-dose chemotherapy (HDCT) in patients with refractory breast cancer is not well established. Forty-two female patients (median age of 46 years) with breast cancer refractory to neoadjuvant chemotherapy received HDCT (cyclophosphamide, carmustine and thiotepa) supported by an autologous peripheral blood stem cells transplant. Their disease had been refractory (defined as less than partial response) to one (18 patients) or two (24 patients) regimens of neoadjuvant chemotherapy. Twenty-nine patients had surgery before HDCT. The best response after surgery, HDCT, and radiation therapy was assessed 60 days after transplantation. Thirty patients had complete remission, eight had a PR, one had a minor response, and three had progressive disease. In seven of 13 patients whose disease was inoperable before HDCT, it became operable. After a median follow-up of 42 months, 21 patients were alive, and 15 remained disease free. Five-year overall survival (OS) was 57% (CI, 50-64%), and the estimated 5-year progression-free survival was 40% (CI, 32-48%). Both OS and PFS were better in patients whose disease became operable after chemotherapy than in those whose disease remained inoperable. A randomized study is warranted in this patient population.

Abstract
The purpose of this study was to identify characteristics significant to survival and progression-free survival in patients with advanced ovarian cancer receiving high-dose chemotherapy. In all, 96 patients received autologous stem cell transplantation. Regimens included paclitaxel with carboplatin (PC), topotecan, melphalan, cyclophosphamide (TMC) and cyclophosphamide, BCNU, thiotepa (CBT). At the time of transplantation, 43% of patients were in clinical CR, 34% were in clinical PR, 18% had progressive disease and 5% had stable disease. There were no treatment-related deaths. The 6-year survival by Kaplan-Meier was 38%. For patients who received transplantation for remission consolidation, the 6-year survival was 53% with a PFS of 29%. On univariate analysis, the CBT regimen, clear cell histology and disease status other than CR prior to treatment were statistically significant adverse prognostic factors. This analysis has demonstrated that patients in clinical remission are most likely to benefit from autologous transplantation, with the exception of patients with clear cell histology. The TMC combination appeared to be superior to the PC and CBT combinations. Comparative studies of different consolidation approaches will be necessary to determine if autologous transplantation is the preferred treatment for this patient population.

Treatment of diffuse alveolar hemorrhage after allogeneic bone marrow transplant with recombinant factor VIIa. Bone Marrow Transplant 2002; 30:975-8.

Abstract
Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening pulmonary toxicity that occurs in 1-21% of patients following bone marrow transplantation. The syndrome is associated with a high mortality rate; and current treatment options are limited. Recombinant factor VIIa (rFVIIa, Novoseven) has recently been approved for the treatment of bleeding in patients with hemophilia A/B with inhibitors. A greater understanding of the mechanism by which rFVIIa restores hemostasis has recently become available; with in vitro evidence supporting that the thrombin burst achieved by rFVIIa is independent of the presence or binding to tissue factor. This insight has suggested a range of other potential clinical uses for the drug; including the setting of pulmonary hemorrhage. We review our experience with using rFVIIa for treatment of DAH in a patient with acute myelogenous leukemia following a matched unrelated donor bone marrow transplant. Boluses of 90 microg/kg rFVIIa were given every 3 h x 4 doses/day, concurrently with high-dose corticosteroids and maintenance of a platelet count >50 000/mm(3). Rapid clinical and radiological improvement was noted within several doses of rFVIIa, with discontinuation of the drug after eight doses. However, the patient's clinical condition began to rapidly deteriorate following cessation of rVIIa, resulting in reinstitution of therapy 24 h later. The patient again exhibited rapid clinical improvement; and rFVIIa was continued for an additional 16 doses with no further evidence of pulmonary hemorrhage noted. No toxicity or adverse events were observed with rFVIIa treatment. Our experience indicates that rFVIIa may be an effective treatment option for DAH post bone marrow transplant; although further clinical studies are needed before recommendations can be made regarding off label use of rFVIIa in this clinical setting.

Factors affecting progression-free survival in hormone-dependent metastatic breast cancer patients receiving high-dose chemotherapy and hematopoietic progenitor cell transplantation: role of maintenance endocrine therapy. Bone Marrow Transplant 2002; 29:861-6.

Abstract
We retrospectively analyzed the effect of maintenance endocrine therapy (MET) after high-dose chemotherapy with hematopoietic progenitor cell transplant (HDCT) on the progression-free survival (PFS) of patients with hormone-dependent metastatic breast cancer (MBC). One hundred and nine consecutive patients with estrogen receptor (ER) and/or progesterone receptor (PgR)-positive MBC, who were progression free for at least 4 months after HDCT with cyclophosphamide, carmustine and thiotepa (CBT), were analyzed. Of these, 55 were non-randomly submitted to MET. After a median follow-up of 34.4 months (17.1-91.0), univariate analysis showed that MET was significantly associated with improved median PFS (31.1 vs 19.2 months, P = 0.022). Complete response to HDCT, pattern of metastatic spread, extent of the disease, single vs multiple metastatic sites, prior endocrine therapy for metastatic disease and prior exposure to any hormonal therapy (adjuvant and/or for the advanced disease) were also associated with PFS at univariate analysis. A multivariate Cox proportional hazard model was fitted to the data in order to correct the effect of MET for the other significant covariates. After correcting for these covariates, MET was still significant, predicting improved PFS (hazard ratio (HR) 0.580, 95% CI; 0.362-0.931). Administration of MET after optimal cytoreduction might result in increased efficacy of HDCT in hormone-dependent metastatic breast cancer.

Abstract
This study investigated the use of a nonablative conditioning regimen to decrease toxicity and achieve engraftment of an allogeneic blood stem cell transplant, allowing a graft-versus-malignancy effect to occur. All patients had follicular or small cell lymphocytic lymphoma after relapse from a prior response to conventional chemotherapy. Patients received a preparative regimen of fludarabine (25 mg/m(2) given daily for 5 days or 30 mg/m(2) daily for 3 days) and intravenous cyclophosphamide (1 g/m(2) given daily for 2 days or 750 mg/m(2) daily for 3 days). Nine patients received rituximab in addition to the chemotherapy. Tacrolimus and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. Twenty patients were studied; their median age was 51 years. Twelve were in complete remission (CR) at transplantation. All patients achieved engraftment of donor cells. The median number of days with severe neutropenia was 6. Only 2 patients required more than one platelet transfusion. The cumulative incidence of acute grade II to IV GVHD was 20%. Only one patient developed acute GVHD of greater than grade II. All patients achieved CR. None have had a relapse of disease, with a median follow-up period of 21 months. The actuarial probability of being alive and in remission at 2 years was 84% (95% confidence interval, 57%-94%). Nonablative chemotherapy with fludarabine/cyclophosphamide followed by allogeneic stem cell transplantation is a promising therapy for indolent lymphoma with minimal toxicity and myelosuppression. Further studies are warranted to compare nonablative allogeneic hematopoietic transplantation with alternative treatment strategies.

Abstract
BACKGROUND Total body irradiation (TBI) is commonly used with autologous bone marrow transplantation (BMT) for treatment of hematologic malignancies. Pulmonary complications of TBI can cause long-term morbidity and mortality. The authors have compared the pulmonary toxicity and efficacy of two different TBI fractionation regimens in otherwise identical autologous BMT protocols. METHODS Between 1990 and 1997 patients younger than 60 years of age with low-grade lymphoma at high risk of treatment failure were enrolled on one of two sequential protocols for autologous BMT differing only in their TBI regimens. The preoperative chemotherapy regimens were identical and consisted of intravenous etoposide (1500 mg/m(2)) for 1 day, intravenous cyclophosphamide (60 mg/kg) for 2 days, and mesna (10 mg/kg). The TBI used in protocol A consisted of twice-daily fractions of 1.7 grays (Gy) for 3 days to a total of 10.2 Gy through lateral fields, with no lung shielding. In protocol B, the TBI consisted of 3 Gy once daily for 4 days to a total of 12 Gy through anteroposterior fields, with lung shielding (5 half-value layers) during the third dose. Fifty-eight patients were treated on protocol A and 24 on protocol B. The groups were equivalent with regard to age, performance status (PS) and gender. Lung function was assessed objectively by pulmonary function tests (PFTs) before and at intervals after TBI. The pulmonary function parameters assessed included forced vital capacity (FVC), forced expiratory volume in 1 second (FEV(1)), forced expiratory flow between 25% and 75% of vital capacity (FEF(25-75)), diffusing capacity for carbon monoxide (DL(CO)), and total lung capacity (TLC). Each patient's post-TBI PFTs were normalized to the corresponding pre-TBI values and analyzed using a random effects model. Clinical pulmonary function status was scored according to Radiation Therapy Oncology Group criteria for acute and late lung toxicity. All clinical pulmonary toxicities such as pneumonitis, pneumonia, and diffuse alveolar hemorrhage, whether specifically related to TBI or not, were scored. Toxicity was classified as either acute (i.e., occurring within 90 days of TBI) or late (i.e., occurring more than 90 days after TBI). The endpoints of analysis were overall survival (OS), freedom from progression, and chronic pulmonary toxicity. Survival, progression, and complication free survival were computed using the method of Kaplan and Meier. RESULTS Three-year actuarial OS rates were 66% and 67% for protocols A and B, respectively. Patients 50 years of age or older had a hazard ratio of death 3.5 times higher than younger patients. Freedom from progression was significantly different for the 2 TBI regimens (P < 0.001; log-rank test): 31% at 3 years in the protocol A group compared with 82% in protocol B group. Patients on protocol A had a rate of progression 4.7 times higher than patients on protocol B. The TBI protocols did not differ significantly in their effects on FVC, FEV(1), FEF(25-75), DL(CO), and TLC. Patients 45 years of age or older had lower average posttransplant values of FEV(1), FVC, and DL(CO) than younger patients. There was no significant difference in acute or late toxicity rates between patients on the two protocols. Seven of the 57 patients in the twice-daily TBI (protocol A) group had acute pulmonary events (Grade 3 or greater), compared with 6 of the 24 patients in the once-daily (protocol B) group (P = 0.19). The 3-year freedom from late complications rate was 80% in the protocol A group and 70% in the protocol B group (P = 0.45). Patients with a PS of 1 had a hazard ratio of late complications 3.2 times greater than patients with a PS of 0 (P < 0.001). CONCLUSIONS It is possible to intensify TBI from a total dose of 10.2 Gy delivered in 6 twice-daily fractions to 12 Gy delivered in 4 once-daily fractions without significantly increasing the risk of pulmonary toxicity. The increased dose may contribute to a decrease in the recurrence rate in these patients. (c) 2001 American Cancer Society.

Abstract
OBJECTIVE The goal of this study was to determine the optimal dose of topotecan when used in combination with high-dose melphalan and cyclophosphamide (TMC), and to assess the toxicity and efficacy of the regimen in patients with advanced ovarian cancer. METHODS Fifty-three patients with persistent or recurrent ovarian cancer were treated. Disease status at study entry included: platinum-sensitive recurrent disease (15 patients), platinum-resistant or refractory recurrent disease (15 patients), positive second-look surgery (16 patients), failure to achieve a primary clinical complete response (CR) (7 patients). Following stem cell mobilization and collection, patients were given cyclophosphamide 1 g/m(2)/day on Days -6, -5, -4; melphalan 70 mg/m(2)/day on Days -3, -2; and topotecan at escalating doses from 1.25 to 4.0 mg/m(2)/day on Days -6 to -2. Peripheral blood stem cells were infused on Day 0. RESULTS The optimal topotecan dose selected for future trials was 4.0 mg/m(2)/day x 5 days. The regimen had acceptable toxicity with no regimen-related death. Toxicity (Bearman toxicity criteria) was limited mostly to grade 1-2 mucositis and diarrhea. The overall response rate of patients with measurable or evaluable disease was 93%. Median survival has not yet been reached, but with a median follow up of 18 months (range: 11-37) 77% of patients are alive. CONCLUSION With a topotecan dose of 4.0 mg/m(2)/day x 5 days, the TMC regimen has acceptable toxicity and produces high response rates. In the setting of ovarian cancer, high-dose chemotherapy should be administered only as part of well-designed clinical trials. TMC should be considered a potential regimen for future randomized trials in patients with advanced ovarian cancer.

Abstract
Acute lymphocytic leukemia remains a difficult disease to treat in adults. Allogeneic bone marrow transplantation can cure some patients with ALL, but GVHD transplant-related mortality and disease relapse remain problematic. Immunotherapeutic approaches aimed at eliminating minimal residual disease and enhancing the GVL effect may decrease relapse rates and improve overall survival. Because of the rarity of this disease in adults, every new patient should be entered in well-designed, peer-reviewed, investigational trial.

Abstract
BACKGROUND Uncontrolled studies have reported encouraging outcomes for patients with high-risk primary breast cancer treated with high-dose chemotherapy and autologous hematopoietic stem cell support. We conducted a prospective randomized trial to compare standard-dose chemotherapy with the same therapy followed by high-dose chemotherapy. PATIENTS AND METHODS Patients with 10 or more positive axillary lymph nodes after primary breast surgery or patients with four or more positive lymph nodes after four cycles of primary (neoadjuvant) chemotherapy were eligible. All patients were to receive eight cycles of 5-fluorouracil, doxorubicin (Adriamycin), and cyclophosphamide (FAC). Patients were stratified by stage and randomly assigned to receive two cycles of high-dose cyclophosphamide, etoposide, and cisplatin with autologous hematopoietic stem cell support or no additional chemotherapy. Tamoxifen was planned for postmenopausal patients with estrogen receptor-positive tumors and chest wall radiotherapy was planned for all. All P values are from two-sided tests. RESULTS Seventy-eight patients (48 after primary surgery and 30 after primary chemotherapy) were registered. Thirty-nine patients were randomly assigned to FAC and 39 to FAC followed by high-dose chemotherapy. After a median follow-up of 6.5 years, there have been 41 relapses. In intention-to-treat analyses, estimated 3-year relapse-free survival rates were 62% and 48% for FAC and FAC/high-dose chemotherapy, respectively (P =.35), and 3-year survival rates were 77% and 58%, respectively (P =.23). Overall, there was greater and more frequent morbidity associated with high-dose chemotherapy than with FAC; there was one septic death associated with high-dose chemotherapy. CONCLUSIONS No relapse-free or overall survival advantage was associated with the use of high-dose chemotherapy, and morbidity was increased with its use. Thus, high-dose chemotherapy is not indicated outside a clinical trial.

Abstract
PURPOSE Hodgkin's disease patients who never achieve complete remission with conventional chemotherapy (i.e., those with primary induction failure) have a poor prognosis. Some subjects who receive high-dose therapy with autologous hematopoietic progenitor-cell infusion experience prolonged progression-free survival. PATIENTS AND METHODS Detailed records from the Autologous Blood and Marrow Transplant Registry (ABMTR) on 122 Hodgkin's disease patients who failed to achieve complete remission after one or more conventional therapy regimens and subsequently received an autotransplant between 1989 and 1995 were reviewed. RESULTS Median age was 27 years (range, 7 to 57 years). Median time from diagnosis to transplantation was 14 months (range, 5 to 38 months). Most patients received high-dose chemotherapy without radiation for pretransplantation conditioning (n = 107). The regimen most frequently used was cyclophosphamide, carmustine, and etoposide (n = 47). Fifteen patients received total-body irradiation (n = 15). The graft consisted of bone marrow (n = 86), blood stem cells (n = 25), or both (n = 11). The 100-day mortality was 12% (95% confidence interval, 7% to 19%). Sixty patients (50%) were considered to have achieved complete remission after autotransplantation; 37 of these had negative imaging studies, whereas scan abnormalities of unknown significance persisted in 23 patients. Twenty-seven patients (22%) had no response or progressive disease after transplantation. Probabilities of progression-free and overall survival at 3 years were 38% (95% confidence interval, 28% to 48%) and 50% (95% confidence interval, 39% to 60%), respectively. In multivariate analysis, "B" symptoms at diagnosis and poor performance score at transplantation were adverse prognostic factors for outcome. CONCLUSION Autotransplants should be considered for patients with Hodgkin's disease who do not achieve complete remission with conventional therapy.

Abstract
BACKGROUND Mismatched family donor and unrelated donor BM transplants are associated with a high risk of acute GvHD. White T-cell depletion is the best method to reduce risk of acute GvHD, there was a reluctance to use T-cell depletion in the mismatched setting because of increased risk of rejection and relapse. Partial T-cell depletion, by the panning of CDS and CD8 positive T cells may reduce complications related to GvHD without compromising outcomes. METHOD In a long-term follow-up of a Phase II study of partial T-cell depletion by panning for BM transplant, 32 recipients received transplants from a single-Ag (HLA A, B, or DR) mismatched family donor; or an HLA serologically-matched unrelated donor. Patients were studied for engraftment, GHD, relapse and survival. RESULTS 30 (94%) of the patients marrow engrafted. The cumulative risk of Grade 2-4 acute GvHD was 62 - 9%; of Grade 3-4 GvHD, 11 - 6%. The 4-year cumulative risk of relapse was 18 - 8% and actuarial survival was 44 - 9%. DISCUSSION Partial T-cell depletion had a low rate of severe acute GvHD without compromising engrafment or relapse risk.

Abstract
PURPOSE To evaluate the feasibility of allogeneic peripheral-blood progenitor-cell (PBPC) transplantation and to assess graft-versus-tumor effects in patients with metastatic breast cancer. PATIENTS AND METHODS Ten patients with metastatic breast cancer that involved the liver or bone marrow were treated with high-dose chemotherapy and allogeneic PBPC transplantation. The median age was 42 years (range, 29 to 55). The median number of metastatic sites was three (range, one to five). The conditioning regimen was cyclophosphamide (6,000 mg/m2), carmustine (BCNU; 450 mg/m2), and thiotepa (720 mg/m2) (CBT regimen). Patients received graft-versus-host disease (GVHD) prophylaxis using cyclosporine- or tacrolimus-based regimens. RESULTS All patients had engraftment and hematologic recovery. Three patients developed grade > or = 2 acute GVHD and four patients had chronic GVHD. After transplantation, one patient was in complete remission (CR), five achieved a partial remission (PR), and four had stable disease (SD). In two patients, metastatic liver lesions regressed in association with skin GVHD after withdrawal of immunosuppressive therapies. The median follow-up time was 408 days (range, 53 to 605). The median progression-free survival duration was 238 days (range, 53 to 510). CONCLUSION We conclude that allogeneic PBPC transplantation is a feasible procedure for patients with poor-risk metastatic breast cancer. The regression of tumor associated with GVHD provides suggestive clinical evidence that graft-versus-tumor effects may occur against breast cancer. Compared with autologous transplantation, allogeneic PBPC transplantation is associated with the additional risks of GVHD and related infections. Allogeneic transplantation should only be performed in the context of clinical trials and its ultimate role requires demonstration of improved progression-free survival.

Abstract
Donor lymphocyte infusions, by virtue of a graft-versus-tumor effect, have been shown to induce remissions in leukemia that recurs after allogeneic bone marrow transplantation. Similar effects have been postulated to contribute to the decreased recurrence rate observed after allogeneic transplantation in non-Hodgkin's lymphoma. This lower recurrence rate may be due to a variety of other mechanisms. We aimed to evaluate the role of graft-versus-lymphoma effects in patients in whom lymphomas recur after allogeneic transplantation. At the time of recurrence, immunosuppressive therapy was withheld. Patients with non-responding disease received an infusion of donor lymphocytes. Patients were observed for response and graft-versus-host disease. Disease in four of nine patients responded to withdrawal of immunosuppressive therapy. A minor response was observed in one of three recipients of donor lymphocyte infusions. Responses were observed among two patients with follicular lymphoma, one with large cell lymphoma and one with lymphoblastic lymphoma. A minor response was observed in a patient with prolymphocytic leukemia/lymphoma. We conclude that withdrawal of immunosuppressive therapy and donor lymphocyte infusion can induce durable remissions in patients with recurrent lymphoma after allogeneic transplantation.

Abstract
PURPOSE To compare outcomes of bone marrow transplants for leukemia from HLA-identical siblings, haploidentical HLA-mismatched relatives, and HLA-matched and mismatched unrelated donors. PATIENTS A total of 2,055 recipients of allogeneic bone marrow transplants for chronic myelogenous leukemia (CML), acute myelogenous leukemia (AML), and acute lymphoblastic leukemia (ALL) were entered onto the study. Transplants were performed between 1985 and 1991 and reported to the International Bone Marrow Transplant Registry (IBMTR). Donors were HLA-identical siblings (n = 1,224); haploidentical relatives mismatched for one (n = 238) or two (n = 102) HLA-A, -B, or -DR antigens; or unrelated persons who were HLA-matched (n = 383) or mismatched for one HLA-A, -B, or -DR antigen (n = 108). HLA typing was performed using serologic techniques. RESULTS Transplant-related mortality was significantly higher after alternative donor transplants than after HLA-identical sibling transplants. Among patients with early leukemia (CML in chronic phase or acute leukemia in first remission), 3-year transplant-related mortality (+/-SE) was 21% +/- 2% after HLA-identical sibling transplants and greater than 50% after all types of alternative donor transplants studied. Among patients with early leukemia, relative risks of treatment failure (inverse of leukemia-free survival), using HLA-identical sibling transplants as the reference group, were 2.43 (P < .0001) with 1-HLA-antigen-mismatched related donors, 3.79 (P < .0001) with 2-HLA-antigen-mismatched related donors, 2.11 (P < .0001) with HLA-matched unrelated donors, and 3.33 (P < .0001) with 1-HLA-antigen-mismatched unrelated donors. For patients with more advanced leukemia, differences in treatment failure were less striking: 1-HLA-antigen-mismatched relatives, 1.22 (P = not significant [NS]); 2-HLA-antigen-mismatched relatives, 1.81 (P < .0001); HLA-matched unrelated donors, 1.39 (P = .002); and 1-HLA-antigen-mismatched unrelated donors, 1.63 (P = .002). CONCLUSION Although transplants from alternative donors are effective in some patients with leukemia, treatment failure is higher than after HLA-identical sibling transplants. Outcome depends on leukemia state, donor-recipient relationship, and degree of HLA matching. In early leukemia, alternative donor transplants have a more than twofold increased risk of treatment failure compared with HLA-identical sibling transplants. This difference is less in advanced leukemia.

Abstract
The success of adoptive immunotherapy for the treatment of leukemia depends on the generation of T cells that can specifically react with malignant cells. Dendritic cells (DCs) are important antigen-presenting cells in the development of antileukemic T-cell responses. In this study, we generated DCs from peripheral blood cells of patients with chronic myelogenous leukemia (CML). CML cells incubated concurrently with granulocyte-macrophage colony-stimulating factor, interleukin-4, and tumor necrosis factor-alpha in vitro developed morphologic and phenotypic characteristics of DCs. Fluorescence in situ hybridization showed the presence of t(9;22) in the nuclei of these cells, indicating that they were leukemic in origin. These cells were potent stimulators of lymphocyte proliferation in specific in vitro assays for DC function. Autologous T cells stimulated with in vitro-generated, leukemic DCs displayed vigorous cytotoxic activity against CML cells but low reactivity to major histocompatability complex-matched normal bone marrow cells. Cytotoxic activity against CML targets was fourfold to sixfold higher using DC-stimulated autologous T cells than with autologous T cells expanded by culture with interleukin-2 alone. DC-stimulated T cells also inhibited growth of CML clonogenic precursors in colony-forming assays in vitro. These results suggest that cytokine-driven in vitro differentiation of CML cells results in generation of DCs with potent T-cell stimulatory function. In vitro-generated DCs can be effectively used as antigen-presenting cells for the ex vivo expansion of antileukemic T cells.

Abstract
We evaluated the response to and toxicity of allogeneic or autologous bone marrow transplantation (BMT) for patients with non-Hodgkin's lymphoma (NHL) who relapsed after autologous BMT. Since 1990, 172 patients have received autologous BMTs in NHL at the MD Anderson Cancer Center and 75 have relapsed. Twelve patients (median age, 42 years), with disease recurrence underwent either allogeneic BMT (eight patients) or a second autologous BMT (four patients). Ten patients received thiotepa, busulfan and cyclophosphamide as conditioning, one patient received cyclophosphamide and total body irradiation and one received BCNU, etoposide, Ara-c and melphalan. The median interval between the first and second transplants was 23.5 months (range 5-80 months). Three patients who underwent allogeneic BMT had refractory relapses, three had a responsive relapse and two were in complete response (CR) at the time of BMT. Five patients received peripheral blood stem cells and three patients, allogeneic bone marrow. Three patients are alive and disease-free at 25, 22 and 7 months after allogeneic BMT. Four patients died of treatment-related causes and one from disease recurrence. All four patients undergoing autologous BMT had responsive relapses. Three patients received peripheral blood stem cells and one patient bone marrow. Two patients are alive and disease-free at 12 and 30 months after autologous transplants. There were no treatment-related deaths; two patients died of disease recurrence. This retrospective study shows that in selected patients, allogeneic or autologous BMT is an effective salvage therapy for NHL which recurs after autologous BMT.

Abstract
OBJECTIVE To determine the current attitude about the use of minors as bone marrow donors in pediatric bone marrow transplantation (BMT) centers in North America. STUDY DESIGN A questionnaire was mailed to 70 North American BMT centers. The questionnaire asked for opinions on a number of ethical and clinical issues pertaining to the use of minors as marrow donors. A case history was included and respondents were asked to check all appropriate answers listed in the survey. RESULTS Fifty-six (80%) of 70 centers responded. There was general consensus on many issues. Pediatricians endorse the validity of parental consent, even in potentially controversial situations. Most are prepared to extract marrow from young (about 6 months of age) infants and are willing to use the same donor more than once. There is general approval of performing BMT with experimental protocols, and the projected outcome of BMT does not affect the decision to use a minor as a marrow donor. There is less consensus regarding the optimal management of minors donating a large volume of bone marrow. CONCLUSION This survey shows a fairly consistent attitude among pediatric BMT centers about the use of minors as marrow donors. The actual management of such donors was not evaluated in detail and requires further study.

Abstract
PURPOSE To evaluate outcomes and identify prognostic factors in allogeneic bone marrow transplantation in patients with end-stage lymphoma. PATIENTS AND METHODS Data were retrospectively analyzed of 64 patients (42 men and 22 women) 18 to 48 years of age with recurrent or refractory lymphoma who underwent allogeneic bone marrow transplantation from matched sibling donors (or in 1 case from a one antigen-mismatched relative) between May 1981 and July 1994. RESULTS Twelve patients survived free of disease. They were 8 of 15 with low-grade lymphoma (disease-free survival at 2 years 59% +/- 13%); 3 of 25 with lymphoblastic lymphoma (disease-free survival 17% +/- 8%); and 1 of 10 with diffuse small non-cleaved cell lymphoma (disease-free (10% +/- 9%). Survival and disease-free survival of patients with low-grade lymphoma were significantly superior compared to any other subgroup of patients (P <0.01). Only 2 patients with low-grade lymphoma had disease progression (9% +/- 9% actuarial risk at 2 years) as opposed to 5 of 15 with intermediate-grade lymphoma (39% +/- 14%), 9 of 25 with lymphoblastic lymphoma (28% +/- 9%), and 8 of 10 (80% +/- 13%) with diffuse small non-cleaved lymphoma. The actuarial risk for disease progression was significantly lower for patients with low-grade lymphoma than for any other histologic subgroup (P <0.02). It was significantly higher for those with diffuse small non-cleaved cell lymphoma than for other histologic subgroups (P < or = 0.003). CONCLUSIONS Allogeneic bone marrow transplantation is an effective procedure in patients with refractory low-grade lymphoma. It results in long-term remissions and should be considered in younger patients with recurrent disease who have a matched sibling donor. The late recurrence in 1 patient indicates the necessity of continued follow-up. A small fraction of patients with end-stage intermediate- and high-grade lymphoma can obtain prolonged disease-free survival, but recurrence and regimen-related toxicity remain major problems. The results could be improved by the development of conditioning regimens with less toxicity and by the use of bone marrow transplantation earlier in the course of the disease.

Abstract
PURPOSE To determine the outcome of HLA-identical sibling bone marrow transplants in advanced Hodgkin's disease. PATIENTS AND METHODS We reviewed the data on 100 consecutive patients with Hodgkin's disease who received HLA-identical sibling bone marrow transplants between April 1, 1982 and August 12, 1992, reported to the International Bone Marrow Transplant Registry (IBMTR). The median interval from diagnosis to transplant was 2.5 years (range, < 1 to 14). All had advanced disease. Eighty-nine of 100 patients were not in remission at the time of transplant. Fifty had pretransplant Karnofsky scores less than 90% and 27 had active infection in the week before transplant. Patients received a variety of conditioning regimens; 45 received total-body radiation. RESULTS The 100-day probability of acute graft-versus-host disease (GVHD) was 35% (95% confidence interval [CI], 26% to 46%); the 3-year probability of chronic GVHD was 45% (95% CI, 31% to 59%). The 3-year probability of relapse was 65% (95% CI, 50% to 78%). The 3-year probability of survival was 21% (95% CI, 14% to 30%). The 3-year disease-free survival rate was 15% (95% CI, 9% to 24%). CONCLUSION HLA-identical sibling bone marrow transplants have a limited role in advanced Hodgkin's disease.

Abstract
The best therapy for persons with acute myelogenous leukemia (AML) in 2nd remission is unknown. Bone marrow transplants from an HLA-identical sibling are reported to be better than chemotherapy but this is controversial. The objective of the study was to compare 3-year leukemia-free survival (LFS) in comparable subjects receiving chemotherapy or a transplant. 485 persons with AML in 2nd remission were studied. The chemotherapy cohort included 244 persons treated on trials of the British Medical Research Council, Eastern Cooperative Oncology Group and MD Anderson Hospital. The transplant cohort included 257 persons transplanted worldwide and reported to the international Bone Marrow Transplant Registry (16 were also chemotherapy subjects.) Subjects were selected for comparable age and year of treatment. Preliminary analyses identified two factors correlated with LFS: age < or = or > 30 years and 1st remission duration < or = or > 1 year; subsequent analyses were partitioned accordingly. Three-year probabilities of treatment-related mortality with chemotherapy and transplants were 7% (95% confidence interval, 3-15%) vs 56% (49-63%). Three-year leukemia relapse probabilities were 81% (74-86%) vs 41% (33-49%). Three-year probabilities of LFS were 17% (12-23%) vs 26 (20-32%). Cohort analysis showed significantly higher LFS with transplants vs chemotherapy in persons < or = 30 years and 1st remissions > 1 year (41% (29-53%) vs 17% (7-32%); P = 0.017) and those in > 30 years with 1st remissions < or = 1 year (18% (9-29%) vs 7% (2-16%); P = 0.046). Others had comparable LFS with both treatments. These data indicate better LFS with HLA-identical sibling transplants than chemotherapy in some persons with AML in 2nd remission.

Abstract
PURPOSE To evaluate the role of allogeneic bone marrow transplantation (BMT) in recurrent low-grade lymphoma. PATIENTS AND METHODS Between 1989 and 1994, 10 patients with chemotherapy-refractory and recurrent low-grade lymphoma were treated with myeloablative therapy and allogeneic BMT. All patients had poor prognostic features and had been extensively pretreated. RESULTS Eight patients achieved a complete remission and none have relapsed at a median follow-up time of 816 days (range, 346 to 1,865). Two patients died of early complications. The actuarial survival and failure-free survival rates are both 80% +/- 12.6%. For surviving patients, the duration of the current remission exceeds that of any previous remission achieved. CONCLUSION These results compare favorably with those for autologous BMT. Allogeneic BMT offers considerable promise for the treatment of patients with poor-prognosis low-grade lymphoma. Its role should be further defined in prospective studies.

Abstract
We performed a prospective randomized, double-blind study to assess the efficacy of selective depletion of CD8+ bone marrow cells in preventing acute graft-versus-host disease (GVHD) in 38 patients undergoing HLA-identical sibling donor bone marrow transplantation for leukemia. All patients received CsA for GVHD prophylaxis. Nineteen patients received marrow depleted of CD8+ cells by ex vivo treatment with anti-leu2, an anti-CD8 mAb and complement; four patients had moderate (grade 1 or 2 acute GVHD) and the only patient who experienced grade 3 manifestations was a technical failure. The control group consisted of 19 patients who received unmodified bone marrow; one patient had grade 1, 4 patients had grade 2, and 10 had grade 3 or 4 acute GVHD. The actuarial incidence of grade > or = 2 acute GVHD was 20 +/- 20% in the CD8-depleted group compared with 80 +/- 18% in the controls (P = 0.004). Death in 5 of the control patients and the single patient in whom CD8 depletion was a technical failure was related to acute GVHD. Graft failure occurred in 2 patients in the CD8-depleted group and in none of the controls. Leukemic relapse occurred in 2 patients receiving CD8-depleted bone marrow and 2 patients in the control group. Seven patients receiving marrow depleted of CD8+ cells are alive and free of leukemia and 9 patients in the control group are alive, 7 of whom remain leukemia-free (P = 0.88). The 3-year actuarial leukemia-free survival is 37 +/- 22% of the CD8-depleted group and 36 +/- 22% for the control group. These results indicate that selective depletion of CD8+ cells from the bone marrow significantly reduces the incidence and severity of acute GVHD.

Hemolysis of transfused group O red blood cells in minor ABO-incompatible unrelated-donor bone marrow transplants in patients receiving cyclosporine without posttransplant methotrexate.

Abstract
Hemolysis most commonly occurs following bone marrow transplant when there is "minor" ABO blood group incompatibility between donor and recipient. The hemolysis has been attributed to destruction of the patient's incompatible erythrocytes by donor-derived anti-A and/or anti-B antibody produced from "passenger" immunocompetent donor lymphocytes. Extraordinary transfusion requirements of group O erythrocytes in a series of patients receiving unrelated minor ABO-incompatible marrow grafts led us to investigate whether this mechanism could account for the extent of hemolysis observed. In seven consecutive minor ABO-incompatible unrelated-donor bone marrow transplant recipients receiving cyclosporine without posttransplant methotrexate, we observed excessive hemolysis. For cases in this index group, a strongly reactive donor-derived ABO blood group antibody was identified coincident with development of hemolysis. Transfusion requirements in the first three patients (26 U of group O erythrocytes each) greatly exceeded the recipient's volume of incompatible erythrocytes, indicating that lysis of transfused group O erythrocytes was also occurring. Pretransplant erythrocyte exchange transfusion with group O erythrocytes performed in the four subsequent patients decreased the severity of hemolysis, but did not prevent it. Among minor ABO-incompatible marrow graft recipients, an analysis of variance demonstrated effects on transfusion requirements due to donor-recipient relationship being unrelated (P less than .002) and the use of posttransplant methotrexate (P = .0001), and there was interaction between these two factors (P less than .001). Bone marrow transplants from unrelated donors resulted in an exaggerated immune response to ABO blood group antigens, which was associated with hemolysis of transfused group O erythrocytes, as well as the patient's ABO-incompatible erythrocytes. This serious complication may be prevented by posttransplant immunosuppression with methotrexate.

Abstract
We analysed data from 114 recipients of HLA-identical sibling transplants who relapsed and received a second transplant between 1978 and 1989. Twenty-nine patients had acute lymphoblastic leukemia, 46 acute myeloid leukemia and 39 chronic myelogenous leukemia. Median (range) interval between first and second transplants was 15 (1-80) months. Following the second transplant, graft failure occurred in 2%, acute graft-versus-host disease (GVHD) in 27% and chronic GVHD in 21% of patients at risk. Risks of interstitial pneumonia and hepatic veno-occlusive disease were higher after the second than the first transplant. Two-year probabilities (95% confidence interval) of treatment-related mortality, relapse and leukemia-free survival were 41% (30-53%), 65% (53-75%) and 21% (14-30%), respectively. Leukemia-free survival was 7% (2-19%) among patients relapsing less than 6 months after their first transplant, with high rates of both relapse, 77% (49-92%), and treatment-related mortality 69% (46-85%). In contrast, leukemia-free survival was 28% (19-41%) in those relapsing more than 6 months after the first transplant; in this group the probability of relapse was 59% (45-72%) and treatment-related mortality 30% (20-43%). Factors correlated with better outcome included a diagnosis of chronic myelogenous leukemia, relapse more than 6 months after the first transplant, acute leukemia in remission prior to the second transplant and good performance status.

Abstract
PURPOSE Despite substantial progress in the treatment of acute myeloid leukemia (AML), fewer than 25% of patients survive free of leukemia for more than 5 years without allogeneic bone marrow transplantation (BMT). In this study we analyzed the results of one or more cycles of high-dose cytarabine-based consolidation chemotherapy as compared with allogeneic BMT in first remission. PATIENTS AND METHODS The results in 28 adult patients, aged 16 to 45 years, who underwent a closely HLA-matched BMT for AML in first remission were compared with those in 54 consecutive, age-matched, adult patients treated with one or more cycles of high-dose, cytarabine-based consolidation chemotherapy. RESULTS After a median follow-up of 4 years, the actuarial risk of leukemic relapse was considerably lower in the transplant group than in the group treated with consolidation chemotherapy (32% +/- 26% v 60% +/- 14%; P = .05). Treatment-related mortality, however, was much higher in the group treated with BMT (32% v 6%, P = .002). The actuarial disease-free survival at 5 years was not significantly different for the two groups (45% +/- 24% v 38% +/- 14%). CONCLUSIONS Our results show that BMT in first remission AML did not offer a disease-free survival advantage over intensive postremission consolidation chemotherapy. Larger studies are needed to identify patients who might benefit most from BMT.

Abstract
Thirty-four patients received bone marrow transplants from unrelated donors. Donors and recipients were phenotypically matched for 6 of 6 HLA-A, B, and DR antigens in 27 cases and at 5 of 6 antigens in 7 cases. Twenty-three patients had leukemia, six had myelodysplasia, and five had aplastic anemia. Twenty-four patients had durable engraftment. Five died of sepsis prior to engraftment. Five patients failed to engraft; 2 of these patients had autologous bone marrow recovery. Seventeen patients developed grade greater than or equal to II acute graft-versus-host disease for an actuarial probability of 67 +/- 20%. The severity of acute graft-versus-host disease and its mortality appeared increased for recipients matched for 5 of 6 HLA-A, B, and DR antigens. Of the 34 patients, 13 (38%) are alive; actuarial survival beyond 6 months is 44 +/- 17%. None of the 25 leukemia and myelodysplasia patients achieving engraftment have relapsed. For leukemia and myelodysplasia recipients of 6 of 6 HLA-matched grafts, actuarial survival at 6 months was 55 +/- 21% compared with 14 +/- 26% for recipients matched for 5 of 6 HLA loci (P = 0.19). Infection and acute graft-versus-host disease were the primary causes of death in the engrafted patients. Survival for aplastic anemia patients was 20%. Late deaths due to pneumonia and bronchiolitis obliterans occurred after one year in 2 patients. Closely matched unrelated donor bone marrow transplants are associated with a higher incidence of graft failure and graft-versus-host disease than typically reported for transplants from HLA-identical siblings, but these preliminary data suggest a lower rate of relapse.

Abstract
One hundred ninety-six patients with acute myelogenous leukemia (AML) were treated with intensive induction chemotherapy using similar daunorubicin/cytarabine/thioguanine regimens. Treatment results of 44 patients who had a documented preleukemic syndrome or cytopenia present for more than 2 months before developing over AML were compared with 152 patients with de novo AML. Eighteen (41%) patients with preleukemia evolving into AML achieved complete remission compared with 111 (73%) patients with de novo AML (P less than .01). Patients with preleukemia-AML had a significantly longer period to recovery of granulocytes. Multivariate analysis indicated that presence of a previous preleukemic syndrome and advancing age were independent poor prognostic indicators for achieving remission. For patients who achieved remission, disease-free survival and overall survival were also inferior for patients with previous preleukemia; disease-free survival was 17 +/- 17% at 3 years compared with 29 +/- 10% in patients with de novo AML (P = .02). These data indicate that intensive chemotherapy has limited efficacy in patients with AML following a preleukemic syndrome. Durable remissions may be achieved in some patients.

Treatment of acute myelogenous leukemia in the elderly. Semin Oncol 1989; 16:51-6.

Abstract
Current data indicate that most elderly patients with acute myelogenous leukemia should be treated with intensive chemotherapy. Most should receive remission induction chemotherapy using cytarabine 100 to 200 mg/m2/d by constant intravenous infusion for five to seven days plus daunorubicin greater than or equal to 30 mg/m2/d for three days. Patients in good overall condition with a near-normal performance status may benefit from a more intensive regimen. Patients achieving remission should receive one to three courses of consolidation chemotherapy. Highly debilitated patients have poor results with any form of therapy, and there has been no apparent advantage for low-dose chemotherapy compared to standard treatment regimens. The intensity of chemotherapy treatment must be individualized to the requirements of the patient.

Clinical, laboratory, and environmental features of infant botulism in Southeastern Pennsylvania. Pediatrics 1985; 75:935-41.

Abstract
Forty-four cases of botulism occurred in infants in Southeastern Pennsylvania between 1976 and 1983. Forty-three were caused by Clostridium botulinum type B. Progressive weakness necessitated ventilatory support in 39 infants. Complications during hospitalization included otitis media in 13 patients and aspiration pneumonia in 11. Eight infants developed the syndrome of inappropriate secretion of antidiuretic hormone and two developed adult respiratory distress syndrome. One infant died of progressive bradycardia despite adequate control of ventilation. Manifestations of autonomic nervous system dysfunction recognized on admission to the hospital were constipation, distention of the urinary bladder, and decreased salivation and tearing. During hospitalization, some infants had unexpected fluctuations of skin color, blood pressure, and heart rate. Infants' strength improved despite persistent intestinal elaboration of toxin. C botulinum was isolated from seven of nine home or work environments sampled. All 44 infants were white and were receiving breast milk at the time of onset of symptoms. The majority had first feedings of nonhuman food substances within 4 weeks prior to onset of symptoms. Delineation of fecal flora in seven infants revealed predominance of enterobacteriaceae. Perturbations of intestinal flora during infancy, especially at weaning, may cause transient permissiveness to colonization by C botulinum.
