Phase II randomized study of dacarbazine, carmustine, cisplatin and tamoxifen versus dacarbazine alone in advanced melanoma patients.

This randomized phase II trial was performed to define the activity and toxicity of the combination of dacarbazine (DTIC), carmustine (BCNU), cisplatin (DDP) and tamoxifen (DBDT regimen) versus DTIC alone in patients with metastatic melanoma. Sixty patients with metastatic melanoma were randomly assigned to receive BCNU 150 mg/m2 intravenously (i.v.) on day 1, cisplatin 25 mg/m2 i.v. daily on days 1 to 3, DTIC 220 mg/m2 i.v. daily on days 1 to 3 and tamoxifen 160 mg orally daily for 7 days prior to chemotherapy (DBDT arm; arm A). Treatment cycles were repeated every 28 days, while BCNU was given every two cycles. The DTIC arm (arm B) patients received DTIC alone 1200 mg/m2 i.v. on day 1, repeated every 21 days. Patients were evaluated every two cycles; responding patients continued the treatment for a maximum of 12 cycles. The overall response rate was 26% in the DBDT arm and 5% in the DTIC arm. Complete responses were 2.5% for DBDT and 0% for DTIC. The median progression-free survival and the median survival were 4 and 9 months, respectively for DBDT, and 2 and 7 months for DTIC. DBDT was associated with significant haematological toxicity: 33% of the patients experienced a grade III or IV neutropenia and 28% a grade III or IV thrombocytopenia. In conclusion, the overall response rate obtained with DBDT was greater than that obtained with DTIC alone; however, this combination increases toxicity with limited impact on overall survival.

Phase I trial of high dose paracetamol and carmustine in patients with metastatic melanoma.

Reduced glutathione (GSH) production by tumour cells has been proposed as a mechanism for resistance to alkylating agents. High levels of paracetamol can deplete intracellular GSH. We conducted a phase I trial of high dose paracetamol and carmustine (BCNU) in patients with advanced malignant melanoma to determine the optimal biological dose and the maximum tolerated dose (MTD) with the goal of increasing sensitivity to BCNU by GSH depletion. Groups of three to five patients received escalating doses of paracetamol (10, 15 or 20 g/m(2)) every 3 weeks. Every other cycle, BCNU (10 mg/m(2)) was given 6.5 h after administration of paracetamol and 45 min before a 20 h infusion of N-acetylcysteine. Once the MTD for paracetamol had been determined, the dose of BCNU was sequentially escalated in subsequent cohorts to 150 mg/m(2). GSH levels were measured in peripheral blood mononuclear cells (PBMCs) and, when available, in tumour biopsies. The MTD of paracetamol was 15 g/m(2). The dose of BCNU was safely escalated to 150 mg/m(2). The most common toxicity was grade II nausea/vomiting. At 15 g/m(2), peak paracetamol levels (median 253 microg/ml) were reached between 1 and 4 h. No changes in GSH levels in PBMCs were seen. There were two partial responses, including a dramatic decrease in hepatic metastases. Treatment of melanoma patients with paracetamol (15 g/m(2)) every 3 weeks and BCNU (150 mg/m(2)) every 6 weeks is safe. The observation of two partial responses has led to a phase II study to evaluate treatment with high dose paracetamol alone or in combination with BCNU.

Topical carmustine (BCNU) in the treatment of mycosis fungoides.

The University of California, San Francisco (UCSF), experience with topical carmustine (BCNU) in the treatment of approximately 200 patients with mycosis fungoides (MF) is summarized. Topical BCNU is an effective treatment for patch- and early plaque-stage MF. Side-effects are usually not a major deterrent to continuation of therapy.

Recall lung pneumonitis due to carmustine after radiotherapy.

A patient who developed pneumonitis immediately after the administration of carmustine (BCNU), within exactly the same field as previous irradiation, is presented. The patient responded partially to corticosteroids. This case suggests that irradiation causes subclinical sensitisation of the lung and can therefore have an additive effect in precipitating lung damage when another pulmonary toxin is encountered at a later date.

Tolerance of normal rabbit eyes to the antineoplastic carmustine.

Various dosages of the anticancer agent 1,3-bis(2-chloroethyl)-1-nitrosourea (carmustine, BCNU) were administered to 28 normal rabbit eyes. Single injections and series of injections were given to determine the tolerance and toxicity levels of this drug when injected directly into the vitreous cavity, the anterior chamber, or the subtenon-retrobulbar space. During a follow-up period of 3 weeks to 4 months, no significant ocular changes were noted following a single injection of BCNU into the vitreous (0.002--0.50 mg) or anterior chamber (0.001--0.250 mg), or 10 daily subtenon-retrobulbar injections (0.5--1.0 mg each). When the daily dosage was increased to 1.5--2.0 mg, corneal damage with stromal infiltration, edema, and vascularization were found after the course of the 10 subtenon-retrobulbar injections in 3 of 6 test animals.

Prognostic factors for response and survival after high-dose cyclophosphamide, carmustine, and etoposide with autologous bone marrow transplantation for relapsed Hodgkin's disease.

Sixty-one patients with relapsed Hodgkin's disease who had failed a mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)- and a doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD)-like regimen were treated with a high-dose combination chemotherapy containing cyclophosphamide, carmustine, and etoposide (CBV) and autologous bone marrow transplantation (ABMT). Fifty-nine patients were treated in relapse and two were intensified early in third remission. Following therapy, 29 patients (47%) were in complete remission (CR), 18 patients (30%) achieved a partial response (PR), and 14 patients (23%) had progressive disease (PD). Among the partial responders, six patients achieved a CR following addition of local radiation therapy to sites of residual nodal disease. For a minimum follow-up of 2 years, 23 patients (38%) are alive and free of disease. High-dose CBV therapy produced severe myelosuppression, and there were four (7%) treatment-related deaths. A multivariate analysis identified failure of more than two prior chemotherapy treatments and poor performance status as important adverse risk factors for survival. Patients who had no adverse risk factor and/or were intensified with CBV while Hodgkin's disease was still responding to conventional chemotherapy, had a CR rate of 63%, with 77% projected 3-year survival; whereas, all other patients had a CR rate of 31%, and a projected 3-year survival of only 18%. Our results demonstrated that CBV and ABMT can induce remission duration of 2 years or greater in a significant proportion of patients with relapsed Hodgkin's disease.

Cyclophosphamide, carmustine, and etoposide with autologous bone marrow transplantation in refractory Hodgkin's disease and non-Hodgkin's lymphoma: a dose-finding study.

Cyclophosphamide, carmustine (BCNU), and etoposide (VP-16) (CBV) is a widely used conditioning regimen in autologous bone marrow transplantation (ABMT) of patients with refractory and relapsed lymphoma. However, the maximum-tolerated dose (MTD) of these agents when used in combination has not been systematically explored. We treated 58 patients (28 with non-Hodgkin's lymphoma [NHL], 30 with Hodgkin's disease [HD]) at seven dose levels of CBV. Doses were cyclophosphamide 4,500 to 7,200 mg/m2, BCNU 450 to 600 g/m2, and VP-16 1,200 to 2,000 mg/m2. The MTD was cyclophosphamide 7,200 mg/m2, BCNU 450 mg/m2, and VP-16 2,000 mg/m2. Six hundred milligrams per square meter of BCNU was associated with five of 18 cases of interstitial pneumonitis versus two of 40 at 450 mg/m2 (P = .02). Treatment-related mortality was 5% at dose levels less than or equal to the MTD and 22% at the highest dose. In this heavily pretreated patient population, most of whom had high volume residual disease, complete responses (CRs) to CBV and ABMT occurred in 25% of assessable patients with NHL and 43% of patients with HD. Thirteen of 28 patients with NHL and 14 of 30 with HD remain free from disease progression with median follow-up of 212 and 215 days, respectively. CBV can be administered with acceptable toxicity over a wide range of doses to patients with refractory and relapsed lymphoma.

Intensive chemotherapy with cyclophosphamide, carmustine, and etoposide followed by autologous bone marrow transplantation for relapsed Hodgkin's disease.

Fifty-six consecutive patients with advanced Hodgkin's disease considered incurable with further conventional chemotherapy were entered into a protocol that included high-dose cyclophosphamide (7.2 g/m2), carmustine (BCNU; 0.6 g/m2), and etoposide (VP16-213; 2.4 g/m2) (CBV) followed by autologous bone marrow transplantation (BMT). Prior combination chemotherapy had failed in all the patients, and all but five had been previously treated with both mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and doxorubicin, bleomycin, and vinblastine with or without dacarbazine (ABV[D]). Thirty-four eligible patients received short-course conventional chemotherapy and/or involved-field radiotherapy before CBV. However, formal restaging was not performed after these conventional therapies; ie, the therapies were not used to select responding patients for transplantation, and all who received such therapy subsequently received CBV and autologous marrow grafts. Forty-four patients (80%; 95% confidence interval [CI], 69% to 91%) achieved a complete response after CBV and BMT. Performance status at protocol entry and the use of conventional cytoreduction therapy before CBV correlated with response. Median follow-up is now 3.5 years (range, 2.5 to 5.0 years). Kaplan-Meier estimates for overall and event-free survival 5 years after transplant are 53% (95% CI, 37% to 67%) and 47% (95% CI, 33% to 60%), respectively. In a univariate analysis, patients with a normal performance status and those without constitutional ("B") symptoms at protocol entry had an improved overall and event-free survival. In a multivariate analysis, only a normal performance status remained significant. Disease progression occurred in 17 patients at an actuarial rate of 39% (95% CI; 26% to 56%) and occurred at previous sites of active disease in all but one patient; our analysis did not identify prognostic factors for progression. Toxic deaths, caused by either neutropenic sepsis or interstitial pneumonitis (IP), occurred in 12 patients (21%; 95% CI, 10% to 32%). CBV with autologous marrow support can produce durable remissions in a substantial number of patients with Hodgkin's disease considered incurable with conventional measures. Regimen refinements may even further improve the therapeutic index of BMT in this malignancy.

High-dose carmustine, etoposide, and cisplatin and autologous bone marrow transplantation for relapsed and refractory lymphoma.

PURPOSE: We determined the toxicity and efficacy of a new preparative autologous bone marrow transplantation (ABMT) regimen in patients with relapsed or refractory non-Hodgkin's lymphoma or Hodgkin's disease. PATIENTS AND METHODS: Forty-four non-Hodgkin's lymphoma and 35 Hodgkin's disease patients 16 to 63 years of age were given intravenous carmustine (BCNU) 600 to 1,050 mg/m2, etoposide 2,400 to 3,000 mg/m2, and cisplatin 200 mg/m2 (BEP) and ABMT. Fifty-nine patients also received 15 to 20 Gy local radiation (involved-field radiotherapy [RI]) to active or previously bulky (> 5 cm) disease sites. RESULTS: Nonhematologic toxicities included nausea, vomiting, high-tone hearing loss, stomatitis, esophagitis, diarrhea, and hepatic and pulmonary toxicity. Two patients died within 40 days of marrow infusion as a result of sepsis and one patient died 7 months after transplant as a result of pulmonary fibrosis. Complete remissions (CRs) were noted in 72% (n = 57) of patients (n = 33 non-Hodgkin's lymphoma; n = 24 Hodgkin's disease). Forty patients (51%) remained alive and disease-free (n = 24 non-Hodgkin's lymphoma; n = 16 Hodgkin's disease) at a median of 17 (range, 8 to 57) months after marrow reinfusion. CONCLUSIONS: This regimen seems to be effective for relapsed lymphoma patients whose disease continues to exhibit chemotherapy sensitivity (16 of 24 [67%] disease-free). Furthermore, this regimen seems to be effective in patients who have never attained a CR (seven of 19 [37%] disease-free).

Randomized comparison of diaziquone and carmustine in the treatment of adults with anaplastic glioma.

PURPOSE: We conducted a phase III trial comparing intravenous (IV) diaziquone (AZQ) and carmustine (BCNU) as single agents in patients with cerebral anaplastic gliomas who had received surgery and radiotherapy. Its purpose was to compare the efficacy of AZQ with that of BCNU, the standard agent for brain tumor chemotherapy. PATIENTS AND METHODS: Randomization between the two regimens occurred 8 weeks after completion of radiotherapy. A total of 251 patients were randomized to receive either AZQ or BCNU, and there were no significant differences between the two treatment arms in any of the known prognostic variables, including age, histologic grade, and Karnofsky performance status (KPS). RESULTS: There was no significant difference in either time to tumor progression or survival between the two treatment arms. Age and histology were strong predictors of outcome, whereas KPS had relatively less effect. Three groups of patients with distinctly different outcomes could be identified: (1) older age (45+) and glioblastoma/gliosarcoma (GBM/GS) patients had a median survival of 37 weeks after randomization; (2) patients with either older age or GBM/GS had a median survival of 61 weeks; and (3) younger age (< 45) and non-GBM/GS (usually anaplastic astrocytoma) patients had a median survival of 147 weeks. Toxicity was primarily hematologic, although acute gastrointestinal toxicity and chronic pulmonary toxicity were more common with BCNU. Patients randomized to AZQ who had significant hematologic toxicity that required dose reduction after the first treatment cycle had significantly longer time to tumor progression and survival than those who did not require dose reduction (P = .011 and .016, respectively). CONCLUSION: There was no significant difference in efficacy between AZQ and BCNU in patients with anaplastic gliomas as tested in this study, although AZQ was somewhat better tolerated.

Randomized trial of hepatic arterial floxuridine, mitomycin, and carmustine versus floxuridine alone in previously treated patients with liver metastases from colorectal cancer.

PURPOSE: This study was designed to determine if hepatic arterial therapy with floxuridine (F), mitomycin, and carmustine (BCNU) (FMB) is superior to hepatic arterial therapy with F alone in previously treated patients with hepatic metastases from colorectal cancer. PATIENTS AND METHODS: Ninety-five patients were randomized to intrahepatic FMB versus intrahepatic F. All patients had tumor progression after systemic chemotherapy (either therapeutic or adjuvant). RESULTS: There was no significant difference in response rate (47% FMB v 33% F; P = .17). Median survival was similar in the two groups, 19.1 months for the FMB group compared with 14.0 months for the F group (P = .23). The overall median survival was 16.8 months. In patients who received prior adjuvant therapy, there was no difference between the two groups, but response rate was high in both (50% FMB v 62% F). The response rate for all patients who had received only prior adjuvant therapy versus all those who had received prior therapy for metastatic disease was 57% and 35%, respectively (P = .066). In the subset of patients whose disease had progressed with prior systemic chemotherapy, the response rate to FMB was greater than that to F (47% v 23%; P = .035). CONCLUSION: The overall partial response rate of 39% and the overall survival of 16.8 months from initiation of intrahepatitis therapy show that hepatic arterial therapy is a reasonable treatment option for patients whose tumor does not respond to systemic therapy or whose disease progresses after adjuvant therapy for colorectal cancer.

Survival comparison of radiosurgery-eligible and -ineligible malignant glioma patients treated with hyperfractionated radiation therapy and carmustine: a report of Radiation Therapy Oncology Group 83-02.

PURPOSE: The purpose is twofold: (1) to identify the malignant glioma patients treated in a trial of hyperfractionated radiotherapy (RT) and carmustine (BCNU) who may have been eligible for a stereotactic radiosurgery (SRS) boost; and (2) to compare survival of such patients with that of those considered SRS-ineligible. PATIENTS AND METHODS: From January 1983 to July 1989, 778 malignant glioma patients were enrolled on Radiation Therapy Oncology Group (RTOG) 83-02, a randomized phase I/II hyperfractionated RT dose-escalation trial with BCNU chemotherapy. The SRS criteria used in a single-institution trial were applied to these patients; they are: Karnofsky performance status (KPS) of greater than 60; well-circumscribed tumor less than 4.0 cm; no subependymal spread; and a location not adjacent to brainstem or optic chiasm. RESULTS: Eighty-nine patients (11.9%) were identified as potentially SRS-eligible. The median survival times (MST) and 18-month survival rates of the 89 eligible and 643 ineligible patients were 14.4 versus 11.7 months and 40% versus 27%, respectively (P = .047). The MST and 18-month survival rate of the 544 SRS-ineligible patients with KPS greater than 60 were 12.1 months and 29%, respectively, and were not statistically inferior to the survival of the SRS-eligible group (P = .21). Multivariate analysis revealed age, KPS, and histopathology to be strongly predictive of survival, and SRS eligibility was also significantly predictive (P = .047). CONCLUSION: SRS-eligible patients enrolled on RTOG 83-02 had survival superior to that of the SRS-ineligible group, and this advantage is mainly due to the selection of a subgroup with a high minimum KPS.

Prognostic factors for treatment outcome in autotransplantation of intermediate-grade and high-grade non-Hodgkin's lymphoma with cyclophosphamide, carmustine, and etoposide.

PURPOSE: We examined a consecutive series of 78 patients with non-Hodgkin's lymphoma treated on prospective protocols with high-dose cyclophosphamide, carmustine (BCNU), and etoposide (CBV) plus autotransplantation to determine prognostic factors for time to treatment failure. PATIENTS AND METHODS: Patients with relapsed, refractory, or poor-risk intermediate- and high-grade non-Hodgkin's lymphoma were treated with CBV with autologous marrow or peripheral-blood progenitor cell support. Patient characteristics before transplantation were examined in univariate analyses by the log-rank test and simultaneously in a Cox proportional hazards regression analysis. A best-predictive model was determined from those variables significant (P < .10) in the univariate test. RESULTS: In univariate analysis, intermediate-grade and immunoblastic lymphoma, responsiveness to pretransplant salvage chemotherapy, and transplantation after primary therapy (first complete response [CR] or partial response [PR]) were associated with prolonged time to treatment failure. In proportional hazards multiple regression analysis, intermediate-grade and immunoblastic histology, responsive disease, and autotransplantation in first CR or PR were positive prognostic factors, and these characteristics are the basis of the best-predictive model for prolonged time to failure. Actuarial 3-year failure-free survival of patients with stable or responding disease at autotransplant was 54%. CONCLUSION: CBV is an effective conditioning regimen in intermediate-grade and immunoblastic non-Hodgkin's lymphoma. Patients with these histologies transplanted while responding to primary therapy, or those with stable disease or disease responding to salvage therapy at the time of autotransplant, are most likely to benefit. Patients with lymphoblastic lymphoma or diffuse undifferentiated lymphoma did poorly with CBV and should be offered alternative therapy.

Phase III comparative evaluation of PCNU and carmustine combined with radiation therapy for high-grade glioma.

PURPOSE: We performed a randomized trial to compare survival distributions and toxicity of radiation therapy (RT) and PCNU with those of RT and carmustine (BCNU) in patients with malignant glioma. PATIENTS AND METHODS: A total of 346 patients with histologically verified supratentorial grade 3 and grade 4 astrocytoma were studied. After surgery, patients were randomly assigned to receive RT 60 Gy in 30 fractions and either PCNU 100 mg/m2 or BCNU 200 mg/m2 every 7 weeks for 1 year and every 10 weeks for the second year. RT and chemotherapy were started within 72 hours of randomization and usually on the same day. Of 334 assessable patients, 72% had partial or radical resection and 71% had grade 4 tumors. Median age was 59 years, and 85% had performance scores of 0 to 2 (Eastern Cooperative Oncology Group [ECOG]). The follow-up duration of 51 living patients ranged from 10.3 to 63.2 months, with a median of 36.2 months. RESULTS: The median survival duration in each group was 47 weeks, and median time to progression was 28 weeks. PCNU produced significantly more leukopenia and thrombocytopenia, whereas BCNU produced significantly more nausea, vomiting, and irritation. CONCLUSION: PCNU has no therapeutic advantage at this dose and schedule and does not warrant further study as a single agent for patients with high-grade glioma.

Escalating dose of mitoxantrone with high-dose cyclophosphamide, carmustine, and etoposide in patients with refractory lymphoma undergoing autologous bone marrow transplantation.

PURPOSE: We conducted a dose-finding study of mitoxantrone (MITO) in combination with high-dose cyclophosphamide, carmustine (BCNU), and etoposide (CBV) in refractory lymphoma undergoing autologous bone marrow transplantation (ABMT). The objective were to determine the following: (1) the maximum-tolerated dose of MITO, (2) the extramedullary toxicity of this regimen, (3) its antitumor activity, and (4) the pharmacokinetic characteristics of MITO at each dose level. PATIENTS AND METHODS: Escalating doses of MITO (15 to 90 mg/m2, single bolus infusion on day -8) followed by CBV were administered to 20 patients (mean age, 38.5 years) with refractory lymphoma. MITO concentrations were determined by high-performance liquid chromatography (HPLC). RESULTS: No toxic death occurred. The maximum-tolerated dose appears to be 75 mg/m2. Two of five patients treated with 90 mg/m2 developed severe organ toxicity, versus zero of 15 treated with doses up to 75 mg/m2. Duration of neutropenia was longer for patients treated with 90 mg/m2 (31.7 days) than for patients treated with doses up to 75 mg/m2 (22.1 days) (P < .05). A linear relationship was observed between administered dose of MITO and (1) plasma peak value, (2) area under the curve (AUC), and (3) plasma concentration on the day of marrow infusion (day 0). Hematologic toxicity was related to the terminal half-life (T1/2) of MITO, and day-0 plasma concentration. A high complete response (CR) rate was observed (60%), and eight of 11 (73%) patients treated with MITO > or = 60 mg/m2 achieved a CR. CONCLUSION: MITO (up to 75 mg/m2) and CBV can be administered with acceptable toxicity and a promising CR rate in this poor-risk population, justifying further phase II studies.

Randomized, double-blind, placebo-controlled trial comparing the response rates of carmustine, dacarbazine, and cisplatin with and without tamoxifen in patients with metastatic melanoma. National Cancer Institute of Canada Clinical Trials Group.

PURPOSE: We designed and conducted a randomized, double-blind, placebo-controlled trial to compare the response rates and survival of patients with metastatic melanoma who received carmustine (BCNU), dacarbazine (DTIC), and cisplatin with tamoxifen, or the same chemotherapy with placebo. PATIENTS AND METHODS: Eligible patients with metastatic melanoma received either BCNU 150 mg/m2 intravenously (i.v.) on day 1, DTIC 220 mg/m2 i.v. daily on days 1 to 3 and on days 22 to 24, and cisplatin 25 mg/m2 i.v. daily on days 1 to 3 and on days 22 to 24 with placebo every 6 weeks, or the same chemotherapy with tamoxifen 160 mg orally daily for 7 days before chemotherapy and 40 mg orally daily throughout the remainder of the treatment cycle. Patients were treated on protocol for up to three cycles depending on the type of response. Assuming that a minimum increase in response rate of 20% would be necessary to conclude that tamoxifen conferred a clinically important benefit, we designed the study with an 80% chance of detecting that difference at the 5% level (two-sided). RESULTS: Between February 1992 and January 1995, 211 patients were accrued, 199 of whom were considered assessable for response and toxicity. The overall response rate was 21% in the placebo group and 30% in the tamoxifen group (P = .187). Complete and partial responses were 3% and 27%, respectively, for the tamoxifen group and 6% and 14%, respectively, for the placebo group. Poor performance status and liver involvement were associated with a reduced likelihood to respond to treatment. Major toxicities were similar in both groups with no statistically significant difference in the rates of deep vein thrombosis, pulmonary thromboembolus, grade 4 neutropenia, or grade 4 thrombocytopenia. CONCLUSION: These results demonstrate that the addition of high doses of tamoxifen to this chemotherapy regimen does not increase the response rate compared with chemotherapy alone in unselected patients with metastatic melanoma.

Phase II study of continuous infusion carmustine and cisplatin followed by cranial irradiation in adults with newly diagnosed high-grade astrocytoma.

PURPOSE: To evaluate the activity and toxicity of carmustine (BCNU) and cisplatin administered as a 72-hour continuous intravenous infusion before radiation in adults with newly diagnosed high-grade astrocytomas. PATIENTS AND METHODS: Fifty-two patients with a Karnofsky performance status greater than 60 and no prior antineoplastic therapy entered this protocol. The median age of the patients was 55 years. Eighty-eight percent had glioblastoma multiforme and 12% had anaplastic astrocytomas. BCNU (40 mg/m2/d) and cisplatin (40 mg/m2/d) were administered concurrently as a 72-hour infusion every 3 to 4 weeks. Radiation was begun 4 weeks after the third cycle of chemotherapy or earlier for progressive disease. Responses required a > or = 50% reduction in contrast-enhancing volume. RESULTS: Forty patients (77%) completed three chemotherapy infusions, five (10%) received two infusions, and seven (13%) received only one. Fifty-one patients completed radiation. Seventeen (42%) patients with measurable disease had a partial response (PR) to chemotherapy, 23 (53%) had stable disease (SD), and two (4%) had progressive disease (PD) on chemotherapy. The median survival time for all patients was 13 months. Survival rates at 1, 2, 3, and 5 years were 62%, 19%, 12%, and 5%, respectively. Grade III to IV leukopenia occurred in 32% of patients; 63% received platelet transfusions and 58% required RBCs. Neutropenic fevers were rare and no intracranial hemorrhages or treatment-related deaths were noted. Nausea, vomiting, peripheral neuropathy, hearing loss, and thromboembolic events were relatively common. CONCLUSION: This chemotherapy regimen appears to have significant activity and may prolong survival in adults with newly diagnosed high-grade astrocytoma.
