A 2-step comprehensive high-dose chemoradiotherapy second-line program for relapsed and refractory Hodgkin disease: analysis by intent to treat and development of a prognostic model.

Salvage of patients with relapsed and refractory Hodgkin disease (HD) with high-dose chemoradiotherapy (HDT) and autologous stem cell transplantation (ASCT) results in event-free survival (EFS) rates from 30% to 50%. Unfortunately, the reduction in toxicity associated with modern supportive care has improved EFS by only 5% to 10% and has not reduced the relapse rate. Results of a comprehensive 2-step protocol encompassing dose-dense and dose-intense second-line chemotherapy, followed by HDT and ASCT, are reported. Sixty-five consecutive patients, 22 with primary refractory HD and 43 with relapsed HD, were treated with 2 biweekly cycles of ifosfamide, carboplatin, and etoposide (ICE). Peripheral blood progenitor cells from responding patients were collected, and the patients were given accelerated fractionation involved field radiotherapy (IFRT) followed by cyclophosphamide-etoposide and either intensive accelerated fractionation total lymphoid irradiation or carmustine and ASCT. The EFS rate at a median follow-up of 43 months, as analyzed by intent to treat, was 58%. The response rate to ICE was 88%, and the EFS rate for patients who underwent transplantation was 68%. Cox regression analysis identified 3 factors before the initiation of ICE that predicted for outcome: B symptoms, extranodal disease, and complete remission duration of less than 1 year. EFS rates were 83% for patients with 0 to 1 adverse factors, 27% for patients with 2 factors, and 10% for patients with 3 factors (P <.001). These results compare favorably with other series and document the feasibility and efficacy of giving uniform dose-dense and dose-intense cytoreductive chemotherapy and integrating accelerated fractionation radiotherapy into an ASCT treatment program. This prognostic model provides a basis for risk-adapted HDT.

Intensive 1,3-bis (2-chloroethyl)-1-nitrosourea (BCNU) monochemotherapy and autologous marrow transplantation for malignant glioma.

Intensive monochemotherapy with carmustine (BCNU) (either 1,050, 1,200, or 1,350 mg/m2) and cryopreserved autologous marrow transplantation was administered to 36 patients with malignant glioma: 27 with progressive disease and nine without progression (adjuvant therapy group). Twelve (44%) of the patients with progressive disease responded; two remain disease free 84 and 60 months after BCNU treatment. In the adjuvant therapy group, three patients remain progression free at 70, 48, and 27 months after BCNU therapy. Tumor progression posttransplantation occurred in 25 patients; six others died of therapy-induced complications. In addition, late neurologic deterioration of unknown cause has developed in two surviving patients. Results from this and other series using intensive BCNU monochemotherapy and autologous marrow transplantation for progressive malignant glioma indicate that prolonged progression-free survival can be produced in an occasional patient, an extremely unusual result with conventional chemotherapy. Although intensive BCNU and autologous marrow transplant regimens are toxic, these results are encouraging. The treatment of patients in an adjuvant fashion with BCNU and other active agents may produce improved results.

High-dose combination alkylating agents with autologous bone marrow support: a Phase 1 trial.

Twenty-nine patients were treated with 31 courses of high-dose combination cyclophosphamide, cisplatin, and carmustine (BCNU) with and without melphalan with autologous bone marrow support. Toxicity was dose related. The maximum tolerated dose for cyclophosphamide, cisplatin, and BCNU in this combination in mg/m2 was 5,625, 165, and 600, respectively. Further dose escalation was precluded by the development of multiple organ toxicity, including venoocclusive disease, refractory thrombocytopenia, and hypertension. Melphalan added to the three-drug combination produced excessive renal and gastrointestinal toxicity. Objective tumor regression occurred in 21 of 25 evaluable cases. The results suggest that selected alkylating agents can be combined in full or nearly full doses before nonmyelosuppressive dose-limiting toxicity precludes further escalation.

Single, sequential, and multiple alkylating agent therapy for multiple myeloma: a CALGB Study.

Four intravenous (IV) alkylating agent regimens were tested in 615 previously untreated patients with multiple myeloma. Patients were randomized to receive melphalan, cyclophosphamide, and carmustine in combination (MCBP), sequentially (Seq-MCBP), or in combination with doxorubicin (MCBPA). The fourth group received IV melphalan (MP) as the only alkylating agent. All groups received a tapering dose of prednisone. Toxicity was similar for all regimens although the nadir of cytopenia was reached more quickly for the regime including melphalan only. Response as measured by reduction in myeloma protein or other parameters were similar for the four treatments. Survival was significantly poorer for the group receiving the alkylating agents in sequence. The survival of high tumor cell load patients who were azotemic was better in the groups treated with IV MP or with the combination of IV MCBP. In view of the simplicity and probable cost savings attached to single-agent treatment, a melphalan/prednisone regimen should be considered as initial therapy for all patients with myeloma.

Phase II diaziquone-based chemotherapy trials in patients with anaplastic supratentorial astrocytic neoplasms.

We treated 103 patients with histologically confirmed anaplastic supratentorial astrocytic neoplasms with either diaziquone (AZQ) and carmustine (BCNU) or AZQ and procarbazine. There were 74 patients with glioblastoma multiforme (GBM) and 29 patients with anaplastic astrocytoma (AA). AZQ plus BCNU produced partial (PR) or unequivocal responses in seven of 32 (21.9%) patients with GBMs and three of ten (30%) patients with AAs. Two patients with GBMs (6.3%) and five patients with AAs (50%) showed stable disease (SD). AZQ plus procarbazine produced PRs or unequivocal responses in five of 42 (11.9%) patients with GBMs and nine of 19 (47.4%) patients with AAs. Eight patients with GBMs (19%) and one patient with an AA (5.2%) showed SD. In addition to histologic diagnosis, only the Karnofsky performance-status (KPS) rating independently influenced response and survival. Differences in response rates between the two regimens were not significant, although estimated median survival after adjusting for performance status was slightly better with AZQ plus BCNU than with AZQ plus procarbazine (P = .031). Neither age nor prior chemotherapy were significant independent risk factors. Toxicity was mild and primarily hematologic. We conclude that these AZQ-based regimens have activity in patients with recurrent anaplastic gliomas, but that they are not clearly superior to other agents in current use. The histologic diagnosis of GBM is associated with a significantly worse prognosis than AA, and we believe that this important distinction must be recognized in phase II as well as phase III trials.

Prolongation of survival for high-grade malignant gliomas with adjuvant high-dose BCNU and autologous bone marrow transplantation.

Employment of postoperative brain irradiation in the initial management of high-grade malignant glial tumors has now become standard. The addition of conventional chemotherapy to irradiation has not significantly improved median survival beyond 1 year. We treated 25 consecutive patients (13 pilot patients and 12 protocol patients) with histologically confirmed unresectable grade 3 or 4 malignant gliomas with high-dose BCNU (carmustine) followed by autologous bone marrow transplantation and whole brain irradiation. Within 3 weeks of initial surgery, each patient had autologous bone marrow stored (median 2 X 10(8) nucleated cells/kg), and then received BCNU 1,050 mg/m2 intravenously (IV). Peripheral granulocytes recovered (greater than 500/microL) at a median of 19 days (range, 10 to 37 days), and platelets recovered (greater than 20,000/microL) at a median of 18 days (range, 13 to 40 days), following bone marrow infusion. Patients received 60 Gy whole brain irradiation when granulocytes were greater than 1,500/microL. Toxicity was well tolerated. Nausea occurred in 19 patients (76%); however, only eight patients (32%) experienced vomiting (mild in three, moderate in five). Eleven patients (44%) did not require empiric antibiotics, six of whom never developed an absolute granulocyte count less than 500/microL. Three patients with a poor performance status died early (one seizure with vomiting and asphyxiation; one, klebsiella urinary tract infection (UTI) with bacteremia; one, candidal pneumonia), and one additional patient who was performing well died of pulmonary hemorrhage. The 13 pilot patients have now been followed for a median of 23 months, with a significant survival advantage compared with the 52 consecutive historical control patients who received similar surgery and radiotherapy without high-dose BCNU (P = .037). The overall study group of 25 patients also has a significant survival advantage when compared with the same historical control group, with a projected median survival of 26 months (P = .007). This new approach using early postoperative intensive therapy consisting of high-dose BCNU, autologous bone marrow transplantation, and whole brain irradiation appears to significantly improve survival.

Repeated high-dose chemotherapy followed by purged autologous bone marrow transplantation as consolidation therapy in metastatic neuroblastoma.

Among 62 children over 1 year of age at diagnosis, who were treated for stage IV neuroblastoma, 33 entered complete remission (CR) or good partial remission (GPR) after conventional therapy and received high-dose chemotherapy (HDC) with in vitro purged autologous bone marrow transplantation (ABMT) as consolidation therapy. The HDC was a combination of carmustine (BCNU), teniposide (VM-26), and melphalan. Thirty-three patients received one course of this regimen, and 18 received two courses. At present, 16 of the 33 grafted patients are alive in continuous CR, with a median follow-up of 28 months. Toxicity of this regimen was tolerable, principally marked by bone marrow depression and gastrointestinal (GI) tract complications. Four complication-related deaths were observed. Relapse post-ABMT occurred most often in the bone marrow. Under this treatment, actuarial disease-free survival is improved compared with that observed under conventional therapy.

High-dose combination alkylating agent therapy with autologous bone marrow rescue for refractory solid tumors.

Twenty-six adults, ages 27 to 60, with refractory metastatic solid tumors were treated with high-dose cyclophosphamide (Cy) + carmustine (BCNU) at one of three escalating dose schedules followed by autologous bone marrow transplantation (ABMT). Toxicity was severe and dose-related, with the maximum tolerated dose for the combination determined to be Cy 160 mg/kg and BCNU 900 mg/m2. Median time to WBC recovery (greater than or equal to 1,000/microL) was 13 days post-ABMT (range, nine to 22 days) and to a platelet count of greater than or equal to 50,000/microL, 22 days (range, 13 to 83 days). Sixteen of 20 evaluable patients (80%) responded to therapy with at least 50% reduction in measurable tumor, and three patients achieved complete remission (CR). Responders included eight of nine evaluable patients with breast carcinoma, two of five with melanoma, two of two with sarcoma, and four of four with colon carcinoma. Response durations were short (median, 4 months), even for complete responders, and relapses generally occurred at sites of previous metastases. In order for this approach to have a more significant impact on overall survival, it may need to be applied earlier in the natural history of the malignancy.

High-dose combination alkylating agents with bone marrow support as initial treatment for metastatic breast cancer.

To evaluate the effect of high-dose chemotherapy in the treatment of metastatic breast cancer, we performed a phase II trial of a single treatment with high-dose cyclophosphamide (5,625 mg/m2), cisplatin (165 mg/m2), and carmustine (600 mg/m2), or melphalan (40 mg/m2) and bone marrow support as the initial chemotherapy for metastatic breast cancer. Twenty-two premenopausal patients with estrogen receptor negative, measurable metastatic disease were treated. Twelve of 22 patients (54%) obtained a complete response at a median 18 days. The overall response rate is 73% (complete and partial response). Median duration of response in the patients achieving complete response was 9.0 months with a median duration of survival for complete responders that is currently undefined. Relapse occurred predominantly at sites of pretreatment bulk disease or within areas of previous radiation therapy. Toxicity was frequent and five patients died of therapy-related complications. The results indicate that a single treatment with intensive combination alkylating agents with bone marrow support can produce more rapid and frequent complete responses than conventional chemotherapy when used as initial chemotherapy for metastatic breast cancer, although median disease-free and overall survival is not improved. Three patients (14%) remain in unmaintained remission beyond 16 months.

Vincristine and prednisone prolong the survival of patients receiving intravenous or oral melphalan for multiple myeloma: Cancer and Leukemia Group B experience.

A total of 589 patients with previously untreated multiple myeloma were randomized to receive daily oral melphalan, pulse-dose intravenous (IV) melphalan, carmustine (BCNU), or lomustine (CCNU). All patients received an initial tapering course of prednisone (Pred). During week 22 (day 154), patients were randomized to receive or not to receive additional therapy with vincristine (VCR) (1 mg/m2) and prednisone (0.6 mg/kg/d for seven days) at 8-week intervals. The influence of VCR/Pred was determined in 302 patients who remained on study beyond 22 weeks after initial therapy. VCR/Pred converted a significant percentage of nonresponders to responders in patients treated with melphalan (55% v 19%, P = .002), but not in patients treated with a nitrosourea (48% v 23%, P = .06). Survival beyond week 22 was significantly longer following the addition of VCR/Pred in patients receiving melphalan (median, 35.3 months v 27.0 months; P = .003) but not in patients receiving BCNU or CCNU (median, 28.1 months v 26.2 months; P = .91). These differences were seen both for oral and IV melphalan. A trend for beneficial effect of VCR/Pred was definitely seen in the good-risk patients (P = .03) but only suggestive for poor-risk patients (P = .12). Following adjustment for VCR/Pred effects, there were no differences in the survival of patients receiving any of the four initial treatments.

Recombinant human granulocyte colony-stimulating factor hastens granulocyte recovery after high-dose chemotherapy and autologous bone marrow transplantation in Hodgkin's disease.

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.

Allogeneic marrow transplantation for refractory Hodgkin's disease.

Eight patients with refractory Hodgkin's disease received intensive combination chemotherapy conditioning with cyclophosphamide, carmustine (BCNU), and etoposide (VP 16-213), and allogeneic marrow transplants. All patients achieved complete responses. Three patients relapsed; two died of Hodgkin's disease and one of chronic graft-v-host disease (GVHD) and infection. In all, four patients died due to transplant-related toxicity. One patient developed a fatal B-cell lymphoproliferative disorder soon after transplantation, and died without evidence of Hodgkin's disease. One patient is alive and free of progression 29 months after transplantation. These data indicate that allogeneic marrow transplantation may be considered as therapy for selected patients with advanced Hodgkin's disease and, despite substantial toxicity, will occasionally result in long-term responses. Better patient selection would likely improve results.

Hepatic venoocclusive disease in autologous bone marrow transplantation of solid tumors and lymphomas.

Retrospective review of 291 solid tumor and lymphoma patients undergoing autologous bone marrow transplantation (BMT) was performed to determine the influence of pretransplant characteristics and preparative regimen to the development of hepatic venoocclusive disease (VOD). Twelve patients (4.1%) developed a clinical syndrome of right upper quadrant (RUQ) tenderness or hepatomegaly, jaundice, and ascites, with or without encephalopathy, within 40 days of marrow reinfusion. Evidence of metastatic liver disease was the only pretransplant characteristic predictive for VOD (P = .0002). Sex, age, histology, hepatitis B serology, and elevated liver function tests were not predictive. No individual preparative agent had a significant effect on the development of VOD. However, a single 2-hour infusion of carmustine (BCNU) (greater than or equal to 450 mg/m2) led to an increased incidence of VOD when compared with the same dose administered in a fractionated schedule (P = .0258) when given with two other chemotherapeutic agents. Seven of eight autopsy specimens confirmed the clinical diagnosis of VOD. The four patients in whom clinical VOD resolved had lower median peak bilirubins (7.3 v 15.9 mg/dL), lower median peak creatinines (2.1 v 4.1 mg/dL), and relatively quick engraftment of neutrophils (mean, 18.7 days). One of the four patients in whom VOD resolved had other grade 4 (life-threatening) toxicities in contrast to eight of eight who succumbed. In summary, VOD is an uncommon complication in autotransplantation of solid tumors and lymphomas. Our data suggest caution in selecting patients with known metastatic liver disease and consideration of a fractionated BCNU schedule especially in combination with other alkylating agents.

Results of the vincristine, doxorubicin, and dexamethasone regimen in adults with standard- and high-risk acute lymphocytic leukemia.

One hundred five untreated adult patients with acute lymphocytic leukemia (ALL) were entered on the vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and Decadron (dexamethasone; Merck Sharp and Dohme, West Point, PA) (VAD) regimen. Induction therapy with VAD and VAD plus cyclophosphamide (CVAD) was followed by a 2-year rotating maintenance program with multiple antileukemic combinations, and included early intensifications with Adriamycin and high-dose cytarabine (ara-C) and a late intensification with cyclophosphamide, carmustine (BCNU), and etoposide (VP-16) (CBV) followed by autologous bone marrow transplantation (BMT). Duration of therapy was 24 to 30 months. Eight-eight patients (84%) achieved complete remission (CR) with VAD-CVAD, and 94 (90%) ultimately had CR with continuation of the maintenance as planned. Induction mortality was 3%; only half of the patients required prolonged hospitalization of 1 week or longer, or intravenous antibiotics. Maintenance therapy was given to 79 patients, while nine with histocompatibility locus antigen (HLA)-matched related donors underwent allogeneic BMT. The median remission duration was 22 months, and the median survival was 19 months. Factors associated with significantly worse CR rates were older age, the presence of hypoalbuminemia or hyperbilirubinemia, L2 or L3 morphology, and myeloid markers on leukemic cells. Those associated with significantly worse remission durations were the presence of elevated leukocyte or absolute peripheral blast counts, Philadelphia chromosome (Ph)-positive or B-cell ALL, L2 morphology, and more than one course to achieve CR. Patients could be divided into standard-risk ALL (28% of patients) and high-risk ALL (72% of patients) with long-term remission rates of 70% versus less than 30%. The 26 patients who underwent CBV autologous BMT had similar long-term outcome compared with 21 patients who did not (older age, medical contraindications, or socioeconomic problems). The presence or absence of myeloid markers on leukemic cells did not affect long-term prognosis. We conclude that VAD therapy is a well-tolerated effective induction regimen. High-risk ALL patients require alternative maintenance investigational approaches.

Chemotherapy is superior to sequential hemibody irradiation for remission consolidation in multiple myeloma: a Southwest Oncology Group study.

Six hundred fourteen previously untreated patients with multiple myeloma were evaluated on this phase III Southwest Oncology Group (SWOG) trial. For remission induction, two noncross-resistant drug combinations (vincristine, melphalan, cyclophosphamide, and prednisone [VMCP] and vincristine, carmustine [BCNU], Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH], and prednisone [VBAP]) were administered with either a direct alternating or a syncopated schedule. Pretreatment serum beta-2 microglobulin (beta 2M) was the single most important prognostic factor for survival (P less than .0001). There was no difference in toxicity, response, or survival by induction chemotherapy schedule (P greater than .7). For consolidation, 180 eligible and responsive patients were randomized to receive either an additional year of VMCP or sequential hemibody radiation (HBI) with vincristine and prednisone (VP) administered between the two HBI courses. Relapse-free survival (26 months) and overall survival (median, 36 months) were better with VMCP than with HBI (median, 20 months and 28 months; P = .04 and .018, respectively). HBI was also evaluated on a nonrandomized basis in 66 patients who achieved either a partial response (PR) or who were nonresponders to induction therapy. While HBI converted 24% of the PR patients to remission status, this effect was only seen in 5% of nonresponding patients. The survival of responsive and nonresponding patients receiving HBI was similar. All HBI groups had an inferior outcome to those receiving VMCP consolidation. Myelosuppression was also significantly worse after HBI. Survival from the time of relapse did not differ between patients randomized to receive VMCP or HBI. Thus HBI induced less durable remissions, but did not render patients less amenable to postrelapse chemotherapy. Our findings do not support the use of HBI in either chemotherapy responsive or nonresponding patients with multiple myeloma.

Myeloablative combination chemotherapy without total body irradiation for neuroblastoma.

Myeloablative treatment intensification in 25 patients diagnosed when older than 12 months of age with stage IV neuroblastoma included sequential delivery of cisplatin 120 mg/m2 x 1, hyperfractionated radiation (2,100 cGy) to the primary site and adjacent lymph nodes, carmustine (BCNU) 200 mg/m2 x 1, melphalan 60 mg/m2/d x 3 (n = 13) or thiotepa 300 mg/m2/d x 3. (n = 12), and etoposide (VP 16) 300 mg/m2/d x 3. Seventy-two hours after the last dose of VP 16, histologically tumor-free and 4-hydroperoxycyclophosphamide (4-HC; 100 mumol/L)-purged autologous bone marrow (ABMT) was infused. Acute toxicities included grade 3 to 4 oral mucositis, grade 1 to 2 diarrhea, and fevers. No patient required infusion of unpurged reserve autografts. At ABMT, 16 patients (group I) were progression-free 6.5 months to 14 months (median, 9 months) from diagnosis: seven remain progression-free 20 months to 46 months (median, 39 months) off therapy, six relapsed 4 months to 17 months post-ABMT, and three died of toxicity (candidiasis, metabolic derangement, and venoocclusive disease [VOD]). The event-free survival of group I patients is 44% at 24 months post-ABMT. Nine patients (group II) were in second remission at ABMT, including three who had relapsed after other transplant procedures: two are progression-free 24 months and 41 months off therapy, four relapsed 3 months to 12 months post-ABMT, and three died of toxicity (aspergillosis, hemorrhagic cystitis, VOD). Only one of 10 relapses involved a primary site, suggesting a beneficial effect of local radiation. In terms of survival or toxicity, an advantage for melphalan or thiotepa was not evident. Regimens such as this may prolong the survival of selected patients with poor-risk neuroblastoma, but concerns over late relapses and toxicity mandate continuing efforts to devise alternative, less risky, and more clearly beneficial approaches for definitive ablation of neuroblastoma.

Multiple myeloma: VMCP/VBAP alternating combination chemotherapy is not superior to melphalan and prednisone even in high-risk patients.

The efficacy of alternating vincristine, melphalan (M), cyclophosphamide, prednisone/vincristine, carmustine, doxorubicin, and prednisone (VMCP/VBAP) polychemotherapy was compared with the M and prednisone (MP) regimen as induction treatment in multiple myeloma (MM). Three hundred four MM patients entered this study between March 1983 and July 1986; the analysis was performed in December 1989. The treatment groups did not show significant differences with respect to major prognostic factors. Median overall survival was 33.8 months. In the VMCP/VBAP and MP arms, after 12 induction chemotherapy cycles, 59.0% and 47.3% (P less than .068) of the patients achieved an M component reduction greater than 50%. No significant difference was observed in the two treatment arms in terms of remission duration (21.3 v 19.6 months, P less than .66) and survival (31.6 v 37.0 months, P less than .28). Patients younger than 65 years did not show any advantage from the alternating polychemotherapy. At diagnosis, the plasma cell labeling index (LI) and serum beta-2 microglobulin (beta 2-m) were evaluated in 173 and 183 patients, respectively. A significantly reduced survival was observed for patients with LI greater than or equal to 2% (16.4 months) or beta 2-m greater than or equal to 6 mg/L (20.4 months). Even in these poor-risk subgroups, VMCP/VBAP was not superior to MP.

Double intensive consolidation chemotherapy in adult acute myeloid leukemia.

Of 115 adult patients with de novo acute myeloid leukemia (AML), 87 (75.5%) achieved complete remission (CR) after induction treatment with zorubicin and conventional doses of cytarabine (Ara-C). Patients under age 45 years with histocompatibility locus antigen-identical sibling underwent bone marrow transplantation (BMT). The others were treated with two courses of intensive consolidation chemotherapy (ICC): course 1 with 4 days of high-dose Ara-C and 3 days of amsacrine (m-AMSA); course 2 with carmustine (BCNU), Ara-C, cyclophosphamide, and etoposide. Forty-two patients received both planned courses, 15 received only the first, and 13 patients could only support conventional maintenance therapy. Four patients died during consolidation. With a median follow-up of 60 months, the disease-free survival (DFS) after ICC at 5 years is 40.3% (+/- 6.5%), with no statistically significant difference between patients receiving one or two courses. The DFS for the 17 transplanted patients is comparable (P = .72) and is lower for the 13 excluded patients (23% +/- 11.5%, P = .046). Age did not influence the probability of remaining in CR. In univariate analysis, three parameters had a negative impact on the 5-year DFS: a high initial WBC count (52% for patients with less than 30 x 10(9) WBC/L v 12% for patients with greater than 30 x 10(9) WBC/L, P = .01), a long delay between induction treatment and course 1 (+/- 60 days; 63% v 29%, P = .01), and a long delay between course 1 and course 2 (+/- 60 days, 61.5% v 28.5%, P = .05). In multivariate analysis (Cox model), only the WBC count remained significant. This study confirms the value of intensive postremission chemotherapy, which can be compared in AML with allogeneic or autologous BMT. It also demonstrates the prognostic value of the initial WBC count. The optimal modalities of ICC remain to be defined by further studies.
