Abstract
The design and results of recent studies of high-dose therapy in metastatic breast cancer, early-stage breast cancer, stage IV neuroblastoma, recurrent or bulky disease and testicular cancer, particularly the proportion of long-term disease-free survivors, are described. The outcome in these subgroups with conventional therapy is described for comparison. The results of these studies suggest that high-dose therapy with autologous marrow support increases the proportion of patients with long-term survival without evidence of disease. Newer supportive care approaches with recombinant growth factors and mobilized peripheral blood cells and recurrent high-dose therapy cycles of non-cross resistant regimens may improve outcome further in these diseases and increase the application to more resistant tumors. The controversy about the importance of and the unexpected high frequency of marrow contamination is outlined.

Abstract
Fifty patients with intermediate- or high-grade non-Hodgkin's lymphoma (NHL) who had relapsed after a complete remission induced by an Adriamycin-containing chemotherapy regimen participated in this prospective pilot study. The patients ranged in age from 16 to 60 years (median 42 years). All patients received dexamethasone, high-dose cytarabine, and cisplatin (DHAP) for two courses at 3- to 4-week intervals. Patients achieving a partial or complete response were scheduled to receive involved-field radiotherapy and high-dose carmustine, etoposide, cytarabine, and cyclophosphamide (BEAC), followed by autologous bone marrow transplantation (ABMT). Among 48 evaluable patients (ie, 1 was lost to follow-up and 1 had no measurable disease) 7 patients obtained a complete response (CR) and another 21 patients achieved partial response (PR), whereas the remaining 20 patients failed. One responder died of treatment-related toxicity, and six others declined ABMT. The patient with no measurable disease did not progress on DHAP and was submitted to ABMT. Twenty-two patients underwent ABMT [20 with BEAC and 2 with cyclophosphamide plus total body irradiation (TBI)] of whom 2 (9%) died of toxicity and 10 relapsed. One patient was a suicide at 28 months post-ABMT in CCR and 9 are alive disease-free 24 months to 32 months (median 30 months) post-ABMT. The actuarial 2-year event-free survival for patients undergoing transplantation is 40%. This prospective multicenter trial documents the ability of DHAP followed by ABMT to produce durable complete remission in a significant proportion of patients with relapsed aggressive NHL. Forty-four percent of all patients with relapsed lymphoma who entered the study actually underwent ABMT and 20% of the total group are projected to be long-term disease-free survivors.

Abstract
Pairs of cell lines from spontaneous human tumors (cervical adenocarcinoma, melanoma, and synovial sarcoma) were established using serum-free culture conditions with and without exogenous epidermal growth factor (EGF). EGF-adapted cultures of melanoma and cervical adenocarcinoma origin secreted higher levels of bioactive transforming growth factor alpha (TGF-alpha) when compared to cultures maintained in the absence of EGF. Depletion of EGF for these EGF-adapted cultures resulted in growth arrest. In contrast, the sarcoma cell lines did not secrete TGF-alpha regardless of the culture conditions but EGF significantly stimulated proliferation of these cells in short-term assays. We show that exogenous EGF induces TGF-alpha production and supports proliferation of tumor cells of various tissue origin but is not essential for in vitro growth factor-deprived conditions.

Abstract
To further improve the effect of high-dose chemotherapy in the treatment of locally advanced and metastatic breast cancer, we sought to develop a second active high-dose noncross-resistant regimen to use in tandem with our customary high-dose regimen of cyclophosphamide, etoposide, and cisplatin (CVP). We performed a phase II trial of high-dose mitoxantrone 30 mg/m2, etoposide 200 mg/m2 every 12 hours x 6, and thiotepa 250 mg/m2 x 3 days (MVT) in 31 patients with heavily pretreated metastatic breast cancer and one with locally advanced chemotherapy-refractory breast cancer. These patients were ineligible for high-dose CVP chemotherapy because of the amount of prior treatment and poor-response status. Of the 32 patients, 14 responded to cycle 1, did not experience any grade 4 toxicity, and received a second cycle of MVT. Overall, seven of 31 patients achieved a complete response (CR; 23%). Four of the 14, who were partial responders to the first cycle, achieved a CR after the second cycle. The overall response rate was 19 of 31 (61%) with an overall median freedom from progression of 4 to 5 months and an overall median survival of 9 months. Toxicity consisted primarily of mucositis (grade 3 or 4 in 69%). The results indicate that high-dose MVT produces significant activity, even in heavily pretreated patients. Administration of a second cycle of high-dose therapy with MVT increased the CR rate, and the morbidity and mortality from the second cycle were not greater than that for the first cycle. Because of the high incidence of grade 3 or 4 mucositis with this regimen, we are currently completing a follow-up study of high-dose mitoxantrone and thiotepa alone.

Abstract
Study of growth factor RNA levels in the stromal cells derived from the adherent layer of long-term bone marrow culture demonstrated constitutive expression of transforming growth factor beta 1 (TGF-beta 1) and macrophage colony-stimulating factor. These cells did not express granulocyte colony-stimulating factor, granulocyte-monocyte colony-stimulating factor, interleukin (IL) 1 alpha, IL-1 beta, IL-3, and IL-6. However, granulocyte colony-stimulating factor expression could be induced by recombinant human IL-1 beta; while IL-6 could be induced by both IL-1 beta and tumor necrosis factor-alpha. No differences could be detected between adherent layers established from normal and benign phase Ph1 chronic myelogenous leukemia bone marrow. The uninduced expression of TGF-beta 1, a potent hematopoietic cell growth inhibitor, suggests that stromal cells play an inherent role in regulating the proliferation of adjacent bone marrow hematopoietic progenitor cells. However, a defect in stromal TGF-beta 1 production cannot account for the profoundly expanded myeloid compartment in chronic phase chronic myelogenous leukemia. In contrast to the constitutive expression of TGF-beta 1 and macrophage colony-stimulating factor, hematopoietic growth factors are only expressed following a proper stimulation.

Abstract
The authors administered high-dose chemotherapy with cyclophosphamide, BCNU (carmustine) and VP-16 (etoposide) plus autologous bone marrow transplantation (ABMT) to 22 adult patients with relapsed acute leukemia in second or subsequent remission. The marrow was not treated ex vivo. The long-term, disease-free survival rate was 14%. Comparison of results with other treatments can be difficult because of patient selection biases. The concept of inversion (achievement of a longer remission with salvage therapy than with prior treatments) is proposed to compare treatment results. Three patients remain in complete remission beyond 4 years, with inversions. More intensive cytoreductive regimens will be needed to improve results.

Abstract
We have used high-dose therapy followed by randomization to receive or not receive autologous bone marrow infusion in 58 stage IV breast cancer patients (all were estrogen receptor-negative [ER-] or primary hormonal refractory). Patients received a median of four courses of induction chemotherapy and if stable or responding received two courses of intensive therapy with cyclophosphamide 4.5 to 5.25 g/m2, etoposide 750 to 1,200 mg/m2, and cisplatin 120 to 180 mg/m2 (CVP). The complete remission (CR) rate after completion of the induction and intensive phases was 55%. Median progression-free interval from induction is 57 weeks with a projected 2-year progression-free survival of approximately 25%. Six of seven patients followed for greater than 2 years are still progression-free. Three favorable features predicted for improved progression-free survival are the following: (1) absent liver involvement, (2) absent soft tissue involvement, and (3) less than or equal to two disease sites (P values of .001, .013, and .048, respectively). Hormonal and menopausal status did not predict for progression-free survival. Major toxicities were infectious secondary to neutropenia, with a 93% incidence of fever and a 38% incidence of sepsis. The treatment-related mortality rate was 9%, with three infectious, one coronary, and one late hemorrhage-related death of unknown cause. Longer follow-up is still needed to truly evaluate the possibility of long-term disease-free survival, but further studies of this approach to high-dose intensification in poor prognostic groups of stage IV breast cancer appear warranted.

Abstract
Twenty-four patients were given the combination of methylprednisolone 100 mg i.v. on day 0, cyclosporine 2 mg/kg i.v. every 12 h starting on day -3 and methotrexate 5 mg/m2 on days 1, 3, and 6, then 10 mg/m2 on days 11 and 18 after allogeneic bone marrow transplantation for hematological malignancies for the prophylaxis of acute graft-versus-host disease. (GVHD). Methylprednisolone was given prior to the marrow infusion for its lympholytic effect. The methotrexate dose on days 1, 3, and 6 was half of that given in other studies to decrease the early toxicities. The outcome of this group is compared with patients transplanted before 1988 and given methotrexate alone, methotrexate with prednisone, or cyclosporine alone. There is no difference in relapse and survival between the groups at this time. The rate of engraftment and incidence of mucositis with the combination is not significantly different from the cyclosporine group. No patient developed greater than grade II acute GVHD with the combination. The probability of grade II or higher acute GVHD with the combination (14%) is significantly less than methotrexate, with or without prednisone or cyclosporine alone.

Abstract
Eighteen adult patients under 55 years of age with acute myelogenous leukemia (AML) who entered remission with induction chemotherapy (AMSA-OAP) received two remission intensification cycles. The first intensification used amsacrine and high dose ara-C (AMSA-HDAC), and the second intensification utilized high dose cyclophosphamide, BCNU and VP-16 (CBV) plus unpurged autologous bone marrow transplantation. This double intensified program features two highly active, non-cross-resistant intensification regimens. We observed a 56% long-term disease free survival rate in this group of patients followed for a minimum time of 40 months, with very tolerable toxicity and no transplantation-related deaths. The bone marrow collected after AMSA-HDAC probably contained very low numbers of leukemic cell (in vivo purge). A multivariate logistic regression model may better define the patient population that benefits from this regimen. If these promising findings are confirmed with larger, randomized studies, this treatment strategy could be used in newly diagnosed patients with AML.

Abstract
This manuscript summarizes our experience with recombinant human granulocyte colony-stimulating factor (rhG-CSF) with high-dose Cytoxan, carmustine and etoposide (CBV in Hodgkin's disease). rhG-CSF regularly shortened the neutropenic phase following autologous bone marrow transplantation. However, this effect was more marked on the latter part of neutrophil recovery than the early part of granulocyte recovery to 100 granulocytes/microliters. The frequency of afebrile episodes was not reduced by rhG-CSF administration, but there was a tendency for the duration of fever to be shortened. Increasing doses and continuous infusion did not hasten the early part of neutrophil recovery needed to prevent the onset of infection, but was more effective than bolus infusion in increasing the rate of late neutrophil recovery. If fevers are to be prevented in this patient population, the duration of an absolute granulocyte count of less than 100/microliters will have to last only a few days. Recombinant hematopoietic growth factors alone do not hasten recovery fast enough to prevent the onset of afebrile episodes. Studies are described using both recombinant growth factor and peripheral blood and bone marrow cells to see if the neutropenic trough can be further shortened over that achievable with growth factor and autologous transplant alone.

Abstract
To determine whether recombinant human granulocyte colony-stimulating factor (rhG-CSF) can accelerate granulocyte recovery after high-dose combination chemotherapy with autologous bone marrow transplantation (ABMT) in patients with Hodgkin's disease, we performed a nonrandomized phase II study using historical controls as a comparison. Eighteen relapsed/refractory Hodgkin's disease patients who received cyclophosphamide at 1.5 g/m2/day (days -6 to -3), carmustine (BCNU) at 300 mg/m2 (day -6), and etoposide (VP-16) at 125 mg/m2 every 12 hours (days -6 to -4), followed by ABMT (day 0) were treated with rhG-CSF at 60 micrograms/kg/day for a maximum of 28 days beginning on day 1. rhG-CSF dosage was gradually diminished and stopped once an adequate granulocyte count was maintained. rhG-CSF significantly accelerated absolute granulocyte count (AGC) compared with historical controls recovery to the 100/microL level (median, 9 days v 13 days; P = .103 x 10(-4), 500/microL level (median, 13 days v 22 days; P = 0.189 x 10(-2), and 1000/microL level (median, 16 days v 30 days levels; P = .125 x 10(-5). Platelet recovery to 50,000/microL was not significantly altered (P = .370). rhG-CSF was well tolerated, bone pain and myalgia being the only side effects noted. rhG-CSF hastens granulocyte recovery after high-dose chemotherapy with ABMT in patients with relapsed/refractory Hodgkin's disease without significant toxicity.

Abstract
A prospective randomized study was done to determine the effect of different doxorubicin (Adriamycin [ADR], Adria Laboratories, Columbus, OH) administration (schedules every week versus every 3 weeks) on the productivity of a cyclophosphamide, ADR, cisplatin (CAP) chemotherapy regimen for patients with non-small cell lung cancer (NSCLC). Electrocardiograms, multigated cardiac scans, echocardiograms, and endomyocardial biopsies were done serially for cardiac monitoring. Of 102 patients, 47 ahd inoperable limited disease (LD), 47 had extensive disease (ED), and eight had no evidence of disease. In the last group chemotherapy was given adjuvantly. Fifty-one patients were entered into each treatment arm. The groups were formed according to extent of disease and were comparable in terms of patient characteristics. In these groups, the overall response rates using both schedules in LD patients were similar: in patients without chest irradiation previously, there was a response of 35% with ADR weekly, and 31% with ADR triweekly; in LD patients with chest irradiation previously, the response was 20% with ADR weekly, and 25% with ADR triweekly; and in ED patients, 16% with ADR weekly, and 11% with ADR triweekly. There was no significant difference in survival between the two treatment groups. However, results for all responders suggested a longer duration of response with weekly than with triweekly ADR (complete plus partial response: 35.8 versus 11.4 weeks, P = 0.06; minor response: 34 versus 11.5 weeks, P = 0.003, respectively). Results also suggested that weekly ADR was less cardiotoxic than triweekly ADR: 29% of patients in the former group had no changes or only minor changes in endomyocardial biopsy results, whereas all patients in the latter group had at least grade 0.5 changes at a similar dosage. The median doses of weekly ADR were higher at the same endomyocardial biopsy-defined toxicity levels. No correlation was found between toxic effects defined by endomyocardial biopsy results and those defined by noninvasive monitoring techniques, although the number of patients assessed was small. Weekly ADR produced less granulocytopenia and a lower incidence of fever (6% versus 16%, P less than 0.001) than did triweekly ADR. Alopecia, nausea, vomiting, and diarrhea were significantly less for weekly ADR than triweekly Adr (P less than 0.0005, less than 0.0005, and less than 0.005, respectively). These data suggest that weekly ADR can achieve the same therapeutic results as the standard triweekly regimen with less cardiotoxicity, myelotoxicity, alopecia, diarrhea, nausea, and vomiting in patients with NSCLC.

Abstract
The effectiveness of ex vivo chemotherapy with drugs, such as vincristine, etoposide, and Adriamycin (doxorubicin, Adria Labs, Columbus, OH) for elimination of residual tumor cells from human bone marrow grafts could be undermined by the presence of multidrug-resistant tumor cells in the bone marrow. Therefore, to supplement chemoseparation, we investigated whether MRK-16, a monoclonal antibody (MoAb) to the surface moiety of multidrug resistance-associated P-glycoprotein antigen, can eliminate drug-resistant tumor cells in the presence of rabbit complement (RC). Two doxorubicin (DOX)-resistant human myeloma tumor cell line, 8226/DOX40 (resistant to 4 x 10(-7) mol/L DOX) and 8226/DOX6 (6 x 10(-8) mol/L DOX) with high and low amounts of cell surface P-glycoprotein, respectively, and the drug-sensitive parent cell line 8226/S were used as tumor models in this study. Using the limiting dilution assay, we have shown that three cycles of treatment with 25 micrograms/mL of MRK-16 MoAb and a 1:4 final dilution of RC eliminated 2.90 +/- 0.10 logs of 8226/DOX40 cells and 1.94 +/- 0.18 logs of 8226/DOX6 cells. One and two cycles of treatment were less effective, eliminating 0.47 +/- 0.40 and 1.94 +/- 0.36 logs of 8226/DOX40 and 0.12 +/- 0.20 and 1.63 +/- 0.58 logs of 8226/DOX6 cells, respectively. The 8226/S cell growth was unaffected by one to three cycles of treatment. The cell kill was not impaired when the antibody plus complement treatment was carried out on a mixture of 8226/DOX40 or 8226/DOX6 cells with a ninefold excess of irradiated bone marrow mononuclear cells (MNCs). The three cycles of treatment with antibody plus complement did not adversely affect granulocyte-macrophage colony-forming unit (GM-CFU) survival in hematologically normal marrows (92.5% to 104% survival) or in myeloma patient marrows (85% to 100%). These results show that it is possible to eliminate drug-resistant myeloma tumor cell lines from the admixed human bone marrow by treatment with MRK-16 MoAb plus RC. This method could prove to be effective for elimination of other drug-resistant tumor cell lines including those of leukemia and solid tumors, and will be further useful for supplementing chemopurging, and immunopurging of bone marrow with other antitumor cell antibodies.

Abstract
A complete hematologic remission was achieved in a patient with therapy-related preleukemia and transfusion-dependent pancytopenia after treatment with recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF). The patient remained in remission for nearly 1 year despite the discontinuation of GM-CSF treatment. Several lines of evidence suggest that normal hematopoiesis was restored after GM-CSF treatment. First, the cytogenetic anomaly, which was present before GM-CSF, completely disappeared after three cycles of treatment. Cytogenetic conversion was documented by conventional karyotypic evaluation of mitotic bone marrow cell preparations as well as by premature chromosome condensation analysis of the nonmitotic cells of bone marrow and peripheral blood. Second, the growth pattern and cycle status of bone marrow granulocyte-macrophage (CFU-GM) and erythroid (BFU-E) progenitor cells were found to be normal during remission. Third, X chromosome-linked restriction fragment length polymorphism-methylation analysis of DNA from mononuclear cells (greater than 80% lymphocytes) and mature myeloid elements showed a polyclonal pattern. These findings suggest that restoration of hematopoiesis in this patient after GM-CSF treatment may have resulted from suppression of the abnormal clone and a selective growth advantage of normal elements.

Abstract
Myeloproliferative disorders are neoplasms of the pluripotent hematopoietic stem cell. Accurate diagnosis and distinction from reactive processes can be difficult therein with cytogenetic analysis only being useful in a minority of patients. Use of X-linked restriction fragment length polymorphism and methylation analysis has enabled clonal analysis to be performed in up to 50% of females, significantly increasing the proportion of analyzable patients over methods dependent on glucose-6-phosphate dehydrogenase heterozygosity. Using hypoxanthine phosphoribosyl transferase and phosphoglycerate kinase probes, we have demonstrated monoclonality of peripheral blood leukocytes in three females with myeloproliferative disorders who had uninformative chromosomal analysis. This technique greatly enhances the diagnosis of early myeloproliferative disorder.

Abstract
We investigated whether monoclonal antibodies (MoAbs) reactive against both acidic and basic cytokeratins alone were sufficient to detect minimal numbers of contaminating epithelial tumor cells in the bone marrow of breast cancer patients. Monoclonal anti-cytokeratin antibodies (AE1 and AE3) were used to stain 14 breast carcinomas by the avidin-biotin-peroxidase technique. Nine tumors (64.3%) showed high reactivity and five (35.7%) showed low or moderate reactivity. Nine MoAbs that proved to be unreactive to light density bone marrow cells by immunoalkaline phosphatase histochemistry were screened for reactivity to breast carcinomas having only low or moderate positivity to cytokeratin antibodies. Three of nine MoAbs showed high percentages of positivity and were selected to supplement the anti-cytokeratin antibodies for immunohistochemical detection of minimal marrow disease in breast cancer patients. A MoAb cocktail was prepared, further tested for reactivity to another five breast carcinomas, and compared with cytokeratin staining alone. The cocktail labeled 100% of carcinoma cells in all the examined specimens. To determine the sensitivity of this panel for detecting minimal numbers of contaminating tumor cells in bone marrow, in vitro mixing experiments were performed. T47D breast carcinoma cells were mixed with bone marrow mononuclear cells at ratios from one tumor cell per 10 bone marrow cells up to one tumor cell per 1 x 10(6) marrow cells, and cytospin preparations were subsequently stained with the MoAb cocktail by the immunoalkaline phosphatase method. Our approach could detect one tumor cell in 1 x 10(5) hematopoietic cells.

Abstract
The in vitro thermal enhancement of Adriamycin (ADR) and Cisplatin (CDDP) was investigated in 18 surgical biopsy specimens of human tumors cultured in the Adhesive Tumor Cell Culture System. Experimental conditions were adopted to simulate "therapeutic" trials: (a) temperature of 37.0 degrees C, 40.5 degrees C or 42.5 degrees C; (b) hyperthermic duration of 30, 60, or 120 min; and (c) 4-dose drug range normalized to human bone marrow toxicity. Drug concentrations that inhibited 90% of tumor growth (IC90) at 37.0 degrees C were compared to the IC90 at 40.5 degrees C and 42.5 degrees C, adjusted for the effect of heat alone. CDDP plus heat was a better combination than ADR plus heat, regardless of the temperature and the exposure duration: significant synergism (p less than 0.001) occurred in 37% of heat-CDDP combinations, as compared with 15% of heat-ADR combinations, and antagonism was significantly lower (p less than 0.001) for heat-CDDP than for heat-ADR (4.4% versus 21% of combinations, respectively). Within the CDDP group, higher temperature and longer heat exposure resulted in an increased incidence of chemosensitivity. No specific pattern of synergism was evident within the ADR group, but a trend toward a higher incidence of antagonistic effects with increasing hyperthermic duration was observed.

Abstract
The objective of this study was to compare the relative in vitro cytotoxicity of bleomycin to that of two newer-generation analogues, tallysomycin S10b and liblomycin. The latter compound is of particular interest as it has recently been shown in preclinical studies to be free of a potential to cause pulmonary injury and yet to possess only a minor potential to produce myelotoxicity. Using the adhesive tumor cell culture system, we evaluated the activity of these three drugs against a panel of 13 human tumors of various types. The range of concentrations chosen was determined and normalized using a nonleukemic permanent mouse hematopoietic progenitor cell line. Those drug concentrations achieving 90% inhibition of growth (IC90) against the murine cell line were: 6.11 microM bleomycin; 7.53 microM tallysomycin S10b; and 0.6 microM liblomycin. When tested against fresh human tumors at equally myelotoxic IC90 concentrations, bleomycin and tallysomycin S10b (nonmyelotoxic compounds) both achieved 90% growth inhibition of all tumors, while liblomycin (a myelotoxic compound) produced an IC90 inhibition in 69% of all tumors. A comparison of drug IC90 values against individual fresh tumors indicated a correlation between bleomycin and its structurally related analogue tallysomycin S10b. No such correlation, however, was seen with liblomycin in comparison to either bleomycin or tallysomycin S10b. The relative activity of liblomycin versus that of bleomycin and tallysomycin S10b varied with individual tumors tested. The response rate of liblomycin, a myelotoxic compound within this normalized range, appears promising. These data represent the first comparison of liblomycin to bleomycin against a spectrum of fresh human tumors using a stem cell assay technique.

Abstract
The effect of epidermal growth factor (EGF) on the in vitro growth of human malignant tumors was compared in serum-supplemented (n = 54) and serum-free (N = 41) media at clonal density to determine the true EGF dependency of tumors. In the complete absence of serum at a 1,000 cells/cm2 seeding inoculation (approximately 100-200 adherent cells), EGF increased growth by greater than 50% in 27 of 41 specimens (66%), and growth increased by 100% or more in 18 of these EGF-sensitive tumors. In 12 serum-free cultures (29%), in vitro growth failed to occur without EGF. With 10% serum supplementation and a lower cell density (250 cells/cm2), EGF increased growth by greater than 50% in 34 of 54 specimens (63%), of which 25 had more than a 100% increase. The maximum growth induced by EGF in serum was usually seen in those tumors already capable of moderate in vitro growth. No difference in response to EGF was detected between specimens from primary tumors (n = 24) and those from metastases (n = 30). Under the stringent culture conditions of complete absence of serum and with tumors seeded at a low cell number, EGF stimulated most primary or metastatic human tumors to establish and sustain short-term in vitro growth successfully.

Abstract
Twenty-one patients with Philadelphia chromosome-positive chronic myelogenous leukemia (CML) in advanced phases were treated with piperazinedione (PIP), total body irradiation (TBI) and allogeneic bone marrow transplantation. Eleven were in blastic transformation, five were in accelerated phase, and five were in second chronic phase. The median age was 29 years (range, 13-41 years); there were 14 males. All patients but one were rendered aplastic by this regimen. Of these, 17 had hematologic engraftment, recovering granulocytes to 1.0 x 10(9)/l in a median of 28 days (range, 11-52 days). Three patients failed to engraft. Of those who engrafted, five relapsed and died of disease, one relapsed and died of a polymicrobial wound infection, nine patients died of treatment-related complications, including graft-versus-host disease, interstitial pneumonitis and sepsis, and one patient developed large-cell lymphoma 27 months after transplant and died of this 18 months later. One patient relapsed after 31 months died of polymicrobial sepsis at 37 months, and one patient remains disease-free at 54+ months. The 3-year survival rate was 14%. Survival at 1 year was related to having a spleen that did not extend beyond 2 cm below the left costal margin at the time of transplantation, and those with a large spleen at initial presentation relapsed more often. PIP-TBI with allogeneic bone marrow transplantation can induce durable remissions in a small proportion of patients in advanced phases of CML, but it is not superior to cyclophosphamide-TBI in this patient group.

Abstract
From July 1980 to November 1985, 109 patients with acute myelogenous and lymphoblastic leukemia who had reached a complete remission (CR) following induction treatment were assigned to a study comparing marrow transplantation with chemotherapy as a postremission treatment. Sixty-nine patients did not have a human leukocyte antigen (HLA)-identical donor, and therefore served as chemotherapy controls; 40 patients had HLA-identical donors, and therefore were assigned to the transplant arm. Of these, 23 were transplanted in first remission and 17 were not. Ten of these 17 were subsequently transplanted in relapse. Initially, only patients with poor prognosis determined by a predictive model were entered into the study. Subsequently, patients with moderately poor prognosis were admitted. Comparing the chemotherapy group with the patients transplanted in first CR, significant control of leukemia relapse in transplanted patients was seen in the subgroup with acute myelogenous leukemia (AML) (P less than .1), and acute lymphoblastic leukemia (ALL) (P less than .01), in the poor (P = .01) and intermediate subgroup (P = .01), and in the good-prognostic groups (P = .05). The survival was affected significantly in only the poor and intermediate subgroups. The use of predictive models might help to select patients for whom bone marrow transplantation is appropriate in first remission and those for whom bone marrow transplantation can be left as the initial treatment of relapse. Predictive models could further be helpful in comparing studies performed at different transplant centers.
