Autologous bone marrow transplantation (ABMT) is the treatment of choice for selected patients with acute myelogenous leukemia, non-Hodgkin's lymphoma, and poor prognosis breast cancer. A possible limitation of this approach is that clonogenic tumor cells could be collected and infused back into the patient along with the normal bone marrow. The major emphasis in our laboratory has been the development of marrow purging regimens for breast cancer patients. This paper describes two investigative approaches hematopoietic progenitor cell protection and selection. We describe how the use of G-CSF in the patients who receive positively selected marrow shortens the rate of engraftment.

Recombinant human granulocyte colony-stimulating factor (rhG-CSF) was given in combination with chemotherapy in elderly patients (greater than or equal to 65 years old) with malignant lymphoma, and the therapeutic efficacy and the incidence of side effects were determined. The subjects consisted of 5 males and 8 females with a median age of 74 years. One patient had Hodgkin's disease and 12 had non-Hodgkin's lymphoma. Regarding lymphoma stage, 2 were in stage II, 3 were in stage III, and 8 were in stage IV. The chemotherapy used was COP-BLAM in 8 patients, COP-BLAM III in 2, IMV-triple P in 2, and ACVP-16 in 1. Treatment with rhG-CSF (1.5 micrograms/kg/day) was commenced during or after the 2nd course of chemotherapy when the neutrophil count dropped to greater than or equal to 1,000/microliters, and was continued until the recovery of either the neutrophil or leukocyte count to 10,000/microliters or 20,000/microliters, respectively. The neutrophil nadir in the non-G-CSF group was 367.3 +/- 231.6/microliters. In the G-CSF group it was 754.6 +/- 116.4/microliters for the second course, with the difference between the 2 groups being significant (p less than or equal to 0.05). Also, the following time periods were significantly shorter in the G-CSF group than the non-G-CSF group: 1) the duration of a neutrophil count less than 1,000/microliters, 2) the duration of fever (greater than or equal to 37.5 degrees C), and 3) the time to recovery from the neutrophil nadir.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the potential impact of recombinant human erythropoietin (EPO) therapy in patients undergoing autologous bone marrow transplantation (BMT) and colony-stimulating factor therapy, we assayed endogenous serum EPO levels and noted blood transfusion requirements in relapsed non-Hodgkin's lymphoma patients treated with high-dose chemo-radiation therapy and autologous BMT. Hematocrit and reticulocyte counts were determined daily, and hematocrit was maintained in the 25-30% range by transfusion according to criteria established by our hospital transfusion committee. EPO levels were measured by radioimmunoassay and were determined at baseline, throughout therapy, and 2 and 3 months after BMT. Serum EPO levels increased more than 25-fold above baseline in most subjects after initiating chemoradiation therapy. No correlation was noted between serum EPO and hematocrit, reticulocyte count or serum creatinine. Total red blood cell units transfused ranged from 4 to 15 (mean 7.7). Mean total donor exposures (red blood cell plus platelet units transfused) were 83.6 units (range 16-175). Serum EPO levels increased early in the course of preparation for autologous BMT and remained elevated for at least 2-3 weeks thereafter although at a lower level. Red blood cell transfusions were required despite very high EPO levels after BMT. Red cell transfusions, moreover, accounted for only 9.2% (69 of 746) of total donor exposures and only 5.8% (42 of 746) of donor exposures during the interval when pharmacologic doses of erythropoietin might be of benefit. In contrast to the potential benefit of colony-stimulating factors such as G-CSF and GM-CSF in BMT, our study suggests limited value for erythropoietin therapy in this setting.

COP-BLAM III therapy was given to 18 patients with non-Hodgkin's lymphoma, and the therapeutic effects as well as adverse effects of the treatment were examined. Of the 18 patients 16 had a complete remission (CR) and 2 showed an partial remission (PR) with a total response rate of 100%. In terms of the stage of disease, CR was achieved in all patients in stage III and in 11 of 13 patients in stage IV. Patients with neutrophil counts less than 1,000/microliters were given rhG-CSF (1.5 micrograms/kg/day, sc), which significantly shortened the duration of neutropenia and decreased the number of days with episodes of fever when compared with those not given rhG-CSF, consequently facilitating the treatment without prolonging the dosing intervals. No serious infection was observed. Adverse effects included neutropenia of less than 1,000/microliters in 6 of the 18 patients (33.3%), thrombocytopenia less than 5 x 10(4)/microliters in 3 (16.7%), nausea and vomiting in 8 (44.4%), peripheral neuropathy in 4 (22.2%) and stomatitis in 4 (22.2%). There were no fatalities caused by the treatment. The above findings indicate that COP-BLAM III therapy is capable inducing high frequency of complete remissions in non-Hodgkin's lymphoma and that its combination with G-CSF can improve the results of the therapy and relieve adverse reactions.

Malignant lymphoma is classified roughly into Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) according to the biological characteristics. Malignant lymphoma in Japan has such characteristics as low incidence of HD, which is usually favorable in prognosis, and high incidence of NHLs, which have further distinctive features of less incidence of favorable follicular B cell lymphoma and of higher incidence of unfavorable diffuse T cell lymphoma including adult T cell leukemia/lymphoma (ATLL) in comparison with those in western countries. As a recent trend of progress in lymphoma study, the introduction of molecular diagnosis by means of gene rearrangement analysis of immunoglobulin and T cell antigen receptor has contributed diagnostically to a definitive determination of T and B cell lineage and cellular monoclonality in malignant lymphoma. On the other hand, remarkable progress has been made in the treatment of malignant lymphoma in recent years. After all, in HD even far advanced cases have been expected to be curable by the combination chemotherapy, for example, MOPP regimen in USA at the present time. Furthermore, in NHL even advanced cases with such aggressive lymphoma as diffuse large cell lymphoma of B cell type have also been able to survive for more than 10 years and may be curable with the frequency of more than 30% in several institutions. Nowadays, the treatment for malignant lymphoma has focussed on multidisciplinary cure-oriented therapy including chemotherapy and radiotherapy in a collaboration of surgical procedure and immunotherapeutic maneuvers. The recent chemotherapy regimen has been called "third generation" ones characterized by alternating non-cross resistant combination and frequent administration of intense drug dose. Furthermore, various biologics such as monoclonal antibodies, several BRMs including IFNs, IL-2 and TNF, and recombinant G-CSF and GM-CSF have been applied in lymphoma treatment to improve the efficacy of combination chemotherapy in new designs of clinical trials.

G-CSF and GM-CSF enhance the rate of neutrophil engraftment in autologous bone marrow transplantation (ABMT) without significantly affecting platelet engraftment. Peripheral blood progenitor cells (PBPC) may enhance rates of engraftment of both neutrophils and platelets. We treated 49 patients undergoing ABMT with a course of G-CSF to obtain PBPC and infused these cells post-transplant with G-CSF in an attempt to determine factors which might correlate with enhanced BM engraftment. Forty-nine patients with Hodgkin's disease, non-Hodgkin's lymphoma or breast cancer undergoing unpurged ABMT were studied. G-CSF priming consisted of an outpatient 8 day course of 5 micrograms/kg/day followed by three leukaphereses (on day 5, 7 and 8) to collect PBPC. Patients then received a chemotherapeutic BMT preparative regimen followed by an infusion of PBPC, autologous BM and the reinstitution of G-CSF (16 micrograms/kg/day). BM engraftment was rapid. The median time to achieve 0.5 x 10(9)/l neutrophils was 10 days compared with a historical BMT control patient population receiving the same preparative regimens of 19 days (p = 0.001). Time to achieve a platelet count of 20 x 10(9)/l was 16 days compared with a historical control of 22 days (p = 0.001). Neutrophil engraftment occurred in all patients by day +14. Marrow engraftment correlated with the total number of CD34+ cells infused as well as the total number of mononuclear cells infused but not the total number of CD34+/CD33- cells infused. The amount of total blood volume pheresed significantly correlated with yield of total mononuclear cells. Prior exposure to radiation therapy negatively correlated with progenitor cell yield.(ABSTRACT TRUNCATED AT 250 WORDS)

This report summarizes our results of sequential treatment with IL-3 and GM-CSF following high-dose chemotherapy with respect to the yield and composition of peripheral blood stem cells (PBSC). Eight patients with high-grade non-Hodgkin's lymphoma were included in the study. Starting 24 h after high-dose cytosine arabinoside (Ara C)/mitoxantrone, IL-3 was given for 6 days, followed by GM-CSF. The increase of circulating hematopoietic progenitor cells during leukocyte recovery varied substantially from patient to patient. Up to a 22-fold interindividual difference was observed for the peak levels of CD34+ cells. A special focus of our study was the antigenic profile of the CD34+ PBSC. On analysis of the antigenic profile of the CD34+ cells, the proportion of CD34+/HLA-DR- and CD34+/CD38- cells representing non-committed hematopoietic stem cells was consistently < 5%. The vast majority of CD34+ cells was found to coexpress CD33 (86.3 +/- 2.1%, mean +/- SEM), reflecting myeloid lineage commitment. CD71 antigen was present on 47.4 +/- 3.0% CD34+ cells with two populations (CD71dim/bright), while the percentage of early B lymphoid (CD34+/CD19+) progenitor cells was extremely low (0.38 +/- 0.13%). We therefore conclude that the cytokines currently available such as G-CSF, GM-CSF or IL-3 facilitate an ontogenetic phenomenon supporting the redistribution of hematopoietic progenitor cells after cytotoxic treatment. Six patients were autografted with the IL-3/GM-CSF-exposed blood stem cells following high-dose conditioning therapy. It is worth noting that no additional BM or hematopoietic growth factors were given post-transplantation.(ABSTRACT TRUNCATED AT 250 WORDS)

A 26-year-old man was admitted to our hospital with cervical tumor and facial edema on July 8, 1991. Examination of chest X-ray and chest CT showed a bulky tumor in the mediastinum and pleural effusion. A pathological diagnosis of non-Hodgkin's lymphoma (diffuse large cell, immunoblastic type) was made by biopsy of the cervical lymph node. MACOP-B chemotherapy or other combination chemotherapy did not achieve complete remission. The man was given a preparative regimen consisting of busulfan at 16 mg/kg orally and 60 mg/kg of etoposide (Bu-Et); 30 mg/kg of etoposide was administered by continuous intravenous infusion for 12 hours on day-5 and day-4, before he received autologous bone marrow on February 20. He was then given 300 micrograms of G-CSF was given to him to accelerate recovery of hematopoiesis from one day after BMT. The neutrophil count to 500/microliters recovered on day 28, and residual tumors disappeared. Although moderate-grade stomatitis and nasal bleeding developed, these toxicities were controllable and no veno-occlusive disease resulted. Regimen-related toxicities of Bu-Et preparatory regimen have been generally considered to be severe, but continuous and separate administration of etoposide as reported in this case may be useful to reduce side effects of this preparatory regimen.

Hemopoietic CD34+ progenitors were isolated by immunomagnetic method from normal bone marrow (BM) or from peripheral blood (PB) of patients with non-Hodgkin's lymphoma treated with chemotherapy and granulocyte colony-stimulating factor (GCSF). Aliquots were seeded in long-term cultures (LTC) on bone marrow-derived stromal layers; non-adherent and adherent clonogenic content of the cultures was assayed weekly. The final recovery and the clonogenic efficiency of the CD34+ cells were slightly higher in PB samples than in BM controls. In long term cultures PB cells sustained hemopoiesis as much as BM cells; at week 3 and 4 PB total mononuclear cells and CD34+ cells showed a non-adherent cell recovery higher than the respective BM controls. Furthermore, PB CD34+ cells were expanded in liquid culture in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) or G-CSF alone or combined with interleukin 3 (IL3), stem cell factor (SCF), interleukin 1 (IL1), interleukin 6 (IL6). The combination of GM-CSF, IL3, SCF, IL1 and IL6 produced the maximum increase of both mononuclear cells (30-fold) and granulocyte-macrophage colony forming units (CFU-GM) (4.6-fold) after 7 days of cultures; yet after 14 days a strong decrease of the CFU-GM occurred. These data suggest that G-CSF following chemotherapy mobilizes both early and committed hemopoietic progenitors.

Peripheral blood progenitor cell (PBPC) populations used for transplantation were analyzed for the presence of CD34+ cells, colony-forming cells (initial CFC), and long-term culture initiating cells (LTC-IC) cultured on irradiated stroma for 5 weeks. Thirty-eight leukapheresis products were studied from 11 patients with breast cancer, 2 with non-Hodgkin's lymphoma and 1 with ovarian cancer harvested during recovery from either cyclophosphamide (CY) chemotherapy or cyclophosphamide-VP16 with G-CSF (CY-VP-G). CY-VP-G products had a threefold higher median number of mononuclear cells collected, a fivefold higher median concentration of CD34 and LTC-IC and a threefold higher concentration of initial-CFC when compared with CY products. CY-VP-G products had a significantly higher ratio of CFU-GM to BFU-E than the CY-mobilized products. Significant correlations of r = 0.89 and r = 0.68 were observed when comparing CD34 and CFC in products from CY or CY-VP-G patients, respectively. Analysis of the regression lines indicated that slopes of these regression lines were significantly different with a ratio of CD34 to initial CFC of 15:1 in the CY-VP-G products versus 5.2:1 with the CY products. These data indicate a higher cloning efficiency of the CD34+ population in the products from CY-mobilized patients. Significant correlations of r = 0.9 (CY) and r = 0.53 (CY-VP-G) were observed when the initial CD34 concentration and the LTC-IC were compared. Comparison of initial CFC with LTC-IC also showed significant correlations (r = 0.94, CY; r = 0.58, CY-VP-G) in samples from both patient groups.(ABSTRACT TRUNCATED AT 250 WORDS)
