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.

Increased expansion and differentiation of cord blood products using a two-step expansion culture.

OBJECTIVE: [corrected] The use of allogeneic cord blood (CB) products as a source of cellular support for patients receiving high-dose chemotherapy has been limited primarily to smaller children due to the low numbers of cells in a CB unit. Ex vivo expansion of CB cells has been proposed as a method to increase the number of cells available for transplantation. Following high-dose chemotherapy administration, we transplanted adult patients with CB expanded in static culture for 10 days, in DM containing stem cell factor (SCF), granulocyte colony-stimulating factor (G-CSF), and megakaryocyte growth and development factor (MGDF). Patients achieved neutrophil engraftment in a median of 26 days (range 15 to 45). In an attempt to hasten the time to neutrophil engraftment, we developed a two-step culture system that results in increased expansion of total nucleated cells and further maturation of neutrophil precursors. MATERIALS AND METHODS: CD34(+) cells isolated from CB products were cultured for 7 days at 37 degrees C in 100-mL Teflon culture bags containing 50 mL of DM containing SCF, G-CSF, and MGDF (100 ng/mL). The cells were harvested from these bags after 7 days of incubation at 37 degrees C and transferred to 1-L Teflon bags containing 1 L of DM plus SCF, G-CSF, and MGDF. After a second culture period of 7 days, the cells were harvested, washed, and assayed for mature (granulocyte-macrophage colony-forming cells [GM-CFC]) and primitive progenitor cells (high proliferative potential colony-forming cells [HPP-CFC]). RESULTS: The two-step cultures resulted in a median total nucleated cell expansion of 438-fold (range 286 to 952, N = 11); the original one-step cultures resulted in a median expansion of 98-fold (range 59 to 350, N = 5). Equivalent expansion of committed progenitor cells (GM-CFC) and primitive progenitor cells (HPP-CFC) was obtained. CD34(+) cells were expanded a median of 29-fold in the two-step cultures (N = 11). The two-step culture contained more mature neutrophil cells, by morphologic examination, than the one-step cultures, similar to ex vivo expanded peripheral blood progenitor cells (PBPC). CONCLUSION: The two-step ex vivo expansion conditions described for CB resulted in increased numbers of total nucleated cells, GM-CFC, HPP-CFC, and CD34(+) cells and morphologically resembled ex vivo expanded PBPC, which have been shown to provide more rapid neutrophil engraftment than unexpanded PBPC. We propose that the availability of increased numbers of expanded CB cells may result in more rapid engraftment of neutrophils following infusion to transplant recipients.

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.

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.

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.

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.

Incidence of tumor-cell contamination in leukapheresis products of breast cancer patients mobilized with stem cell factor and granulocyte colony-stimulating factor (G-CSF) or with G-CSF alone.

We have assessed tumor contamination of peripheral blood progenitor cells (PBPC) in 203 high-risk breast cancer patients who were prospectively randomized to mobilization with stem cell factor (SCF) plus granulocyte colony-stimulating factor (G-CSF) versus G-CSF alone. The patients then received high-dose cyclophosphamide, cisplatin, and carmustine (BCNU) with PBPC support. One bone marrow aspirate obtained before treatment, one whole blood specimen obtained before cytokine infusion, and one to five leukapheresis products were tested for the presence of tumor cells by an alkaline phosphatase immunocytochemical technique with a targeted sensitivity of 1.7 tumor cells per 10(6) hematopoietic cells. Tumor cells were detected in the bone marrow, peripheral blood, and/or PBPC of 21 patients (10%). In 14 patients, bone marrow specimens were tumor-positive; in seven patients, premobilization whole blood specimens were tumor-positive, and in eight patients, leukapheresis products were tumor-positive. In five patients, repetitive or multiple specimens were tumor-positive, and in three cases, marrow, peripheral blood, and PBPC products were all tumor-positive. Nine of the patients in whom tumor cells were found in marrow or peripheral blood were clinical stage II to III and 12 were clinical stage IV. Nine of the tumor-positive patients were in the SCF + G-CSF arm and 12 were in the G-CSF arm. Tumor cells were detected in leukapheresis products of eight patients: three in the G-CSF + SCF arm and five in the G-CSF arm. We conclude that detectable tumor-cell contamination of bone marrow, peripheral blood, and/or PBPC occurred in approximately 10% of patients in this trial and was observed in stage II to III patients, as well as in stage IV patients. No significant difference could be found in the rate of PBPC tumor-cell contamination between patients who received SCF + G-CSF compared with those who received G-CSF alone. Neither mobilization regimen was found to increase the rate of tumor-cell contamination when control premobilization blood samples were compared with leukapheresis products.

A randomized phase 3 study of peripheral blood progenitor cell mobilization with stem cell factor and filgrastim in high-risk breast cancer patients.

This randomized study compared the number of leukaphereses required to collect an optimal target yield of 5 x 10(6) CD34(+) peripheral blood progenitor cells/kg, using either stem cell factor (SCF) at 20 micrograms/kg/d in combination with Filgrastim at 10 micrograms/kg/d or Filgrastim alone at 10 micrograms/kg/d, from 203 patients with high-risk stage II, III, or IV breast cancer. Leukapheresis began on day 5 of cytokine administration and continued daily until the target yield of CD34(+) cells had been reached or a maximum of 5 leukaphereses performed. By day 5 of leukapheresis, 63% of the patients treated with SCF plus Filgrastim (n = 100) compared with 47% of those receiving Filgrastim alone (n = 103) reached the CD34(+) cell target yield. There was a clinically and statistically significant reduction (P <.05) in the number of leukaphereses required to reach the target yield for the patients receiving SCF plus Filgrastim (median, 4 leukaphereses) compared with patients receiving Filgrastim alone (median, 6 or more leukapherses; ie, <50% of patients reached the target in 5 leukaphereses). All patients receiving SCF were premedicated with antihistamines, albuterol, and pseudoephedrine. Treatment was safe, generally well tolerated, and not associated with life-threatening or fatal toxicity. In conclusion, SCF plus Filgrastim is a more effective peripheral blood progenitor cell (PBPC)-mobilization regimen than Filgrastim alone. In addition to the potential for reduced leukapheresis-related morbidity and costs, SCF offers additional options for obtaining cells for further graft manipulation.

Ex-vivo expansion of hematopoietic progenitor cells: preliminary results in breast cancer.

Ex-vivo expanded progenitor cells have been proposed as a source of cells to support high-dose chemotherapy and to decrease or eliminate the period of neutropenia following transplantation. To date, no clinical studies using ex vivo expanded cells, have demonstrated any decrease in the time to neutrophil or platelet recovery, although a number of clinical studies have been performed using a variety of growth factor cocktails and culture conditions. Over the past 6 years we have developed a static culture system that results in optimal expansion of myeloid progenitor cells. We have initiated a clinical study to evaluate this culture system in breast cancer patients receiving peripheral blood progenitor cells (PBPC) to support high-dose chemotherapy. CD34 selected cells were cultured for 10 days in 800 ml of defined media (Amgen Inc.) containing 100 ng/ml each of rhSCF, rhG-CSF and rhMGDF in 1L teflon bags (American Fluoroseal) at 20,000 to 50,000 cells per ml. After culture the cells were washed with 3 volumes of PBS to remove all media and growth factors and reinfused on day 0 of transplant followed by daily administration of rhG-CSF. On day +1 the patients received an unexpanded PBPC product to ensure the durability of the graft. Patients transplanted with expanded PBPC cells recovered neutrophil counts (ANC > 500/microl) as early as day 4 post transplant with a median of 6 days (range 4 to 14 days). In comparison, our historical control group of patients (N=175) had a median time to neutrophil engraftment of 9 days (range 7 to 24 days). A second cohort of patients were transplanted with expanded cells alone and a similar rapid engraftment was obtained. The first patients are now over 70 days post transplant with durable engraftment. No effect on platelet recovery has been observed in any patients to date. These data demonstrate that PBPC expanded under the conditions defined can significantly shorten the time to engraftment of neutrophils.

Autologous stem-cell transplantation for solid tumors in adults.

Over the last decade, high-dose chemotherapy (HDC) with autologous stem-cell transplantation has been explored for a variety of solid tumors in adults, particularly breast cancer, ovarian cancer, and nonseminomatous germ-cell tumors. Response of phase II studies are encouraging in most cases, and, in certain settings, seem clearly superior to historical results of conventional-dose chemotherapy. The value of HDC for adult solid tumors is a highly controversial issue, currently being addressed in large randomized phase II trials. This article reviews the results of HDC in different diseases and depicts potential directions of future progress.

Philadelphia chromosome-negative engraftment after autologous transplantation with granulocyte-macrophage colony-stimulating factor for chronic myeloid leukemia.

Autologous bone marrow transplantation (BMT) has not been curative in chronic myeloid leukemia (CML), because of the inability to purge CML from the autograft and the absence of the allogeneic T cell-mediated antileukemic activity. However, recent advances demonstrate that normal progenitors can be selected from CML marrows by a variety of techniques, including isolation by their small size. Furthermore, we found that myeloid growth factors have a potent antileukemic effect against CML progenitors in vitro by inducing their terminal differentiation. Based on these data, we initiated a trial of autologous BMT in patients with high-risk CML. Autografts were processed in an attempt to enrich for normal progenitors, first by isolating small cells by counterflow centrifugal elutriation and then incubating them in granulocyte-macrophage colony-stimulating factor (GM-CSF) for 72 hours. After a conditioning regimen of busulfan and cyclophosphamide, all patients received GM-CSF daily for 2 months. The median age of the 13 patients in the trial was 45 years (range 17-56 years). The median duration of disease before BMT was 24 months (range 13-72 months). Eight patients were in chronic phase (CP), and five were in accelerated phase (AP). All patients failed to achieve a cytogenetic response to interferon-alpha and were 100% Philadelphia chromosome (Ph)+ before BMT. There were three transplant-related deaths, all AP patients. All of the remaining 10 patients engrafted with some degree of Ph- hematopoiesis; despite high-risk features, nine patients engrafted 100% Ph-. All patients relapsed cytogenetically at a median of 6 months (range 4-22 months). These results demonstrate that autologous BMT can consistently induce complete Ph- engraftment in CP patients. GM-CSF appears to produce a clinical antileukemic effect against CML after autologous BMT.

The utilization of cytokines in stem cell mobilization strategies.

High-dose myeloablative chemotherapy supported by peripheral blood progenitor cell (PBPC) transplant is rapidly replacing bone marrow transplant to treat a number of chemosensitive cancers. Numerous investigators have studied the relationship of CD34+ cell dose and engraftment kinetics in an effort to help define minimum and optimum target stem cell doses. A number of studies suggest that reinfusion of > or = 5 x 10(6) CD34+ PBPCs results in prompt and durable platelet engraftment. Mobilization of stem cells can be accomplished through use of chemotherapy alone, colony-stimulating factors, or a combination of the two. Strategies to improve PBPC yields include filgrastim in combination with chemotherapy or with other hematopoietic growth factors. In this paper, the advantages and disadvantages of these strategies will be discussed, and the results of a recently conducted, randomized, controlled phase 3 clinical trial in breast cancer patients receiving either SCF plus filgrastim or filgrastim alone for PBPC mobilization will be reviewed.

Post-mortem incidental finding of cytomegalovirus oophoritis after an allogeneic stem cell transplant.

Cytomegalovirus (CMV) disease is a common and serious complication of allogeneic stem cell transplantation (SCT). Its two most frequent manifestations are interstitial pneumonitis and gastroenteritis. We describe here the first reported case of CMV ovarian infection in an allo-SCT recipient. This patient was included in a clinical trial of high-dose chemotherapy (HDCT) with HLA-matched peripheral SCT for metastatic breast cancer. She expired 53 days after transplantation from organ failure unrelated to her CMV oophoritis.

Modification of the pharmacokinetics of high-dose cyclophosphamide and cisplatin by antiemetics.

Interpatient variability in exposure to certain chemotherapy agents can influence patient outcome, particularly with high-dose chemotherapy. We evaluated the possibility of a pharmacokinetic (PK) drug-drug interaction between the antiemetic agents and high-dose cyclophosphamide, cisplatin and BCNU (CPA/cDDP/BCNU). Twenty-three self-selected patients treated with high-dose CPA/cDDP/BCNU followed by autologous hematopoietic progenitor cell support (AHPCS) received ondansetron, lorazepam and diphenhydramine as antiemetics. PK parameters for each chemotherapeutic drug in the regimen were compared with those of 129 patients who received exactly the same chemotherapy but an antiemetic regimen substituting prochlorperazine for ondansetron. In addition, we performed a review of the English literature for reported drug-drug interactions between antiemetics and chemotherapy agents that led to modifications in any PK parameters of the chemotherapy agent. Our retrospective study showed that the mean area under the curve (AUC) for both cyclophosphamide (76,600 vs 90,600 microg/ml/min, P=0.001) and cisplatin (525 vs 648 microg/ml/min, P = 0.01) were significantly lower in the ondansetron group when compared with the prochlorperazine group. The AUC for BCNU was not significantly different in both groups (544 vs 677, P = 0.43). We found only one report of modifications of the PK parameters of high-dose chemotherapy agents due to drug-drug interactions with the most commonly used antiemetics in a review of the English literature between 1966 and 1995. We concluded that the AUC of high-dose cyclophosphamide and cisplatin are significantly lower when ondansetron, as opposed to prochlorperazine, is used as the antiemetic. The small sample size and heterogeneity of this group of patients precludes any outcome analysis of pharmacodynamic endpoints such as toxicity or antitumor effect. Nevertheless, the potential for interactions between antiemetics and chemotherapy agents should be taken into account when using different high-dose chemotherapy regimens.

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.

Depletion of CD34+ CD4+ cells in bone marrow from HIV-1-infected individuals.

Pancytopenia as a consequence of bone marrow abnormalities is commonly seen in HIV-infected individuals. To examine the effect that HIV-1 has on hematopoietic cells, we compared hematopoietic properties of bone marrow samples from HTV+ patients at various stages of disease with bone marrow samples from uninfected donors. While the absolute number of recovered CD34+ cells and the cloning efficiency of these cells did not differ significantly in HIV+ donors, the percentage of CD34+ CD4+ cells was significantly depleted in late-stage HIV+ patients. We observed a direct correlation between the numbers of CD34+ CD4+ cells in the bone marrow and the peripheral CD4 count. Further characterization of the CD34+ CD4+ subpopulation demonstrated that these cells expressed lower levels of HLA-DR on their surface compared with CD34+ CD4- cells, suggesting an immature phenotype. We also found evidence for expression of HIV-1 coreceptors CXCR-4 and CKR-5 message and protein in CD34+ bone marrow cells. While this finding suggested that hematopoietic cells might be susceptible to HIV infection at an early stage of maturation, thus affecting different cell lineages as they matured, we did not find any evidence for infection of HIV in these cells. These data suggest that HIV affects early hematopoietic progenitor cells either directly or indirectly, and in particular CD34+ CD4+ cells. This finding has important implications for disease pathogenesis and for application of gene therapy approaches that use CD34+ hematopoietic cells.

Prognostic and predictive factors for patients with metastatic breast cancer undergoing aggressive induction therapy followed by high-dose chemotherapy with autologous stem-cell support.

PURPOSE: We performed a retrospective review to determine predictive and prognostic factors in patients with metastatic breast cancer who received induction therapy, and, if they responded to treatment, high-dose chemotherapy. PATIENTS AND METHODS: Patients with metastatic breast cancer received induction therapy with doxorubicin, fluorouracil, and methotrexate (AFM). Partial responders then received immediate high-dose chemotherapy, whereas those who achieved complete remission were randomized to immediate or delayed high-dose chemotherapy with hematopoietic stem-cell support. We performed a retrospective review of data from these patients and used Cox proportional hazards regression models for analyses. RESULTS: The overall response rate for the 425 patients enrolled was 74% (95% confidence interval, 70% to 78%). Multivariate analysis of data from all 425 patients revealed that positive estrogen receptor status (P =.0041), smaller metastatic foci (</= 2 v > 2 cm) (P =. 0165), a longer disease-free interval from initial diagnosis to diagnosis of metastases (</= 2 v > 2 years) (P =.0051), and prior treatment with tamoxifen (P =.0152) were good prognostic signs for overall survival. Patients who had received prior adjuvant therapy (P =.0001) and those who developed liver metastases (P =.0001) had decreased long-term survival. In the subgroup of responders to AFM induction, multivariate analysis showed that those with visceral metastases did less well (P =.0006), as did patients who had received prior adjuvant therapy (P =.0023). However, those who had received tamoxifen therapy in the adjuvant setting did better (P =. 0143). CONCLUSION: The chance for long-term remission with induction therapy with AFM and high-dose chemotherapy is increased for hormone receptor positive-patients with nonvisceral metastases who have not received prior adjuvant chemotherapy and have long disease-free intervals.
