Phase 2 study of BCNU and temozolomide for recurrent glioblastoma multiforme: North American Brain Tumor Consortium study. Neuro Oncol 2004; 6:33-7. [PMID: 14769138 PMCID: PMC1871975 DOI: 10.1215/s1152851703000309] [Citation(s) in RCA: 47] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2003] [Accepted: 08/26/2003] [Indexed: 11/19/2022] Open
Abstract
The purpose of this study was to evaluate the activity, measured in terms of progression-free survival (PFS) and response rates, of 1,3-bis(chloro-ethyl)-1-nitrosourea (BCNU) plus temozolomide in adult patients with recurrent glioblastoma multiforme. The phase 2 dose and schedule for this trial was BCNU 150 mg/m(2) i.v. followed in 2 h by temozolomide 550 mg/m(2) as a single oral dose. Treatment was repeated every 6 weeks for up to 8 cycles unless tumor progression was documented. The primary end point was PFS at 6 months (PFS-6). Response was a secondary end point, measured by MR imaging, neurological status, and steroid requirements prior to each 6-week cycle. The median age of eligible patients was 53, and 89.5% had no prior chemotherapy. All patients were evaluable for toxicity and time to progression. The PFS-6 was 21%. Overall survival was 68% at 6 months and 26% at 1 year. The MRI response for 36 patients was 2 partial responses, 2 minor responses, 19 cases of stable disease, and 13 immediate progressions. Median survival was 34 weeks, and median PFS was 11 weeks. Toxicity was primarily myelosuppression; no toxic deaths occurred. Historical phase 2 study data in this patient population show a PFS-6 of 15%. Recent data for use of temozolomide alone have shown a PFS-6 of 21%. We conclude that BCNU plus temozolomide when used in these doses and schedule has only modest activity, with significant toxicity, and appears to be no more effective than single-agent temozolomide.

Abstract
BACKGROUND Survival after first-line therapy is poor for patients with glioblastoma. The role of second-line treatment for recurrent disease is controversial. The authors studied the outcome in a subset of patients with glioblastoma who were selected for an aggressive reintervention strategy at the time of progression. Their objectives were to improve patients' overall survival with sustained quality of life and to make comparisons with overall survival in unselected patients. METHODS Overall, 168 patients were eligible for retrospective analysis. Ninety patients received specific therapy for disease recurrence (reintervention group) by specific criteria. RESULTS In the reintervention group, promising median overall survival (mOS) results after diagnosis (61.5 weeks) and progression (33 weeks) were obtained. The progression-free survival (PFS) rate at 12 months and the overall survival rate were superior in the reintervention group (71% at 12 months and 32% at 24 months) compared with the total cohort (45% and 20%, respectively) and the standard group (15% and 5%, respectively). A matched-pair analysis (n = 46 in each group), with an mOS period of 65.5 versus 28.5 weeks, confirmed these data. Quality of life was stable or slightly improved during reinterventions in a subset of patients treated within clinical studies. CONCLUSIONS The majority of patients in the current series were treated with a reintervention strategy, which had an impact on PFS and mOS. A second resection, focal radiotherapy (in selected cases), and additional chemotherapeutic regimens should be considered for patients with recurrent glioblastoma.

Abstract
PURPOSE With limited response rates and potential toxicity of chemotherapeutic treatment in patients with recurrent glioma, reliable response assessment is essential. Currently, the assessment of treatment response in glioma patients is based on the combination of radiologic and clinical findings. However, response monitoring with computed tomography (CT) or magnetic resonance imaging (MRI) is hampered by several pitfalls and is prone to interobserver variability. The aim of this study was to establish the value of thallium-201 single-photon emission computed tomography (201Tl-SPECT) as a predictor of overall survival and response to chemotherapy in recurrent glioma, and to compare the value of 201Tl-SPECT with that of CT and MRI. PATIENTS AND METHODS We studied patients who underwent CT or MRI and 201Tl-SPECT before chemotherapy (n = 57), and patients who also had undergone CT or MRI and 201Tl-SPECT after two courses of chemotherapy (n = 44). The value of the radiologic variables (CT-MRI tumor size, 201Tl-SPECT tumor size, and maximal tumor intensity) at baseline and at follow-up in predicting overall survival, and the percentage of patients alive and progression-free at 6 months (APF6) were examined using Cox regression and logistic regression analysis. RESULTS Both at baseline and at follow-up, 201Tl-SPECT maximal tumor intensity was the strongest predictive variable and was inversely related to overall survival and APF6. In particular, progression of maximal tumor intensity after two courses of chemotherapy was a powerful predictor of poor outcome. CONCLUSION 201Tl-SPECT is superior to conventional CT-MRI in the early prediction of overall survival and response to chemotherapy in patients with recurrent glioma.

Abstract
PURPOSE The role of chemotherapy in the primary treatment of malignant glioma remains controversial. The results from the German-Austrian Glioma trial (GAG, 1983 to 1988) demonstrated a survival benefit for chemotherapy using carmustine (BCNU) plus teniposide (VM26) over BCNU alone in addition to radiotherapy in patients with a Karnofsky performance score (KPS) more than 60. The Neuro-Oncology Working Group (NOA) of the German Cancer Society therefore compared the efficacy of nimustine (ACNU) plus VM26 and ACNU plus cytarabine (Ara-C) chemotherapy in addition to standard radiotherapy in patients with newly diagnosed malignant glioma. PATIENTS AND METHODS From 1994 to 2000, 375 patients were randomly assigned to receive radiotherapy and cycles of ACNU 90 mg/m2 intravenously (IV) on day 1 and VM26 60 mg/m2 IV on days 1 to 3 (n = 183), or ACNU 90 mg/m2 IV on day 1 and Ara-C 120 mg/m2 IV on days 1 to 3 (n = 179), in 6-week intervals. Thirteen patients were not eligible after central neuropathology review. The remaining 362 patients had glioblastoma (n = 301) or anaplastic glioma (n = 61). RESULTS Median survival and 2-year survival rates were 17.3 months and 25% for ACNU plus VM26, and 15.7 months and 29% for ACNU plus Ara-C in glioblastoma, and 60 months and 88% for ACNU plus VM26 and 62.5 months and 72% for ACNU plus Ara-C in anaplastic glioma. Multivariate analysis revealed no survival advantage for either arm or for subpopulations defined by histology, age, or KPS. Hematologic toxicity was more prominent in the ACNU plus Ara-C arm. CONCLUSION The median survival times and 2-year survival rates for patients with anaplastic glioma and glioblastoma achieved in the NOA-01 trial compare favorably with historical trials and with the Radiation Therapy Oncology Group database. The toxicity profile favors ACNU plus VM26 for further evaluation.

Abstract
PURPOSE Advances in brain tumor biology indicate that transfer of p53 is an alternative therapy for human gliomas. Consequently, we undertook a phase I clinical trial of p53 gene therapy using an adenovirus vector (Ad-p53, INGN 201). MATERIALS AND METHODS To obtain molecular information regarding the transfer and distribution of exogenous p53 into gliomas after intratumoral injection and to determine the toxicity of intracerebrally injected Ad-p53, patients underwent a two-stage approach. In stage 1, Ad-p53 was stereotactically injected intratumorally via an implanted catheter. In stage 2, the tumor-catheter was resected en bloc, and the postresection cavity was treated with Ad-p53. This protocol provided intact Ad-p53-treated biologic specimens that could be analyzed for molecular end points, and because the resection cavity itself was injected with Ad-p53, patients could be observed for clinical toxicity. RESULTS Of fifteen patients enrolled, twelve underwent both treatment stages. In all patients, exogenous p53 protein was detected within the nuclei of astrocytic tumor cells. Exogenous p53 transactivated p21CIP/WAF and induced apoptosis. However, transfected cells resided on average within 5 mm of the injection site. Clinical toxicity was minimal and a maximum-tolerated dose was not reached. Although anti-adenovirus type 5 (Ad5) titers increased in most patients, there was no evidence of systemic viral dissemination. CONCLUSION Intratumoral injection of Ad-p53 allowed for exogenous transfer of the p53 gene and expression of functional p53 protein. However, at the dose and schedule evaluated, transduced cells were only found within a short distance of the injection site. Although toxicity was minimal, widespread distribution of this agent remains a significant goal.

Abstract
Current treatment strategies for high-grade gliomas are inadequate with high rates of disease recurrence and poor overall survival. Photodynamic therapy has been extensively investigated for a variety of tumours including high-grade gliomas. We have previously described a novel boronated porphyrin (BOPP) which has highly selective uptake by tumour cells. A Phase I study documented that BOPP at a dose of 4mg/kg was well tolerated. We report here the survival data arising from this Phase I study. Overall 28 patients (pts) with high-grade gliomas were treated with BOPP photodynamic therapy with a median overall survival (OS) of 14 months (2-48+ months). Sixteen pts had glioblastoma multiforme (GBM) with a median OS of 8 months (2-38+). Of 9 pts with recurrent GBM, the median OS was 11 months (3-38+), with 56% surviving at least 12 months. In conclusion, BOPP photodynamic therapy was associated with encouraging survival particularly in the recurrent GBM setting.

Abstract
PURPOSE The use of thalidomide as an antiangiogenic agent has met with only limited success in the treatment of malignant gliomas. On the basis of preclinical data demonstrating synergistic antitumor activity when antiangiogenic agents are combined with cytotoxic agents, we explored the clinical activity of the combination of thalidomide and carmustine (BCNU) in patients with recurrent high-grade gliomas. PATIENTS AND METHODS Patients with a histologic diagnosis of high-grade glioma and radiographic evidence of tumor progression after standard surgery, radiation, and chemotherapy were eligible for the study. Patients received BCNU 200 mg/m2 on day 1 of every 6-week cycle, and 800 mg/d of thalidomide that was escalated to a maximal dose of 1,200 mg/d as tolerated. RESULTS A total of 40 patients (38 with glioblastomas, two with anaplastic gliomas) were accrued to the study. The combination of thalidomide and BCNU was well tolerated; mild myelosuppression and mild to moderate sedation were the most common side effects. The median progression-free survival (100 days) and the objective radiographic response rate (24%) for patients with glioblastoma compared favorably with data from historical controls. CONCLUSION This is one of the first clinical trials to evaluate the strategy of combining a putative antiangiogenic agent with a cytotoxic agent in patients with primary brain tumors. Our data demonstrate that thalidomide in combination with BCNU is well tolerated and has antitumor activity in patients with recurrent high-grade gliomas. Although the combination seems to be more active than either agent alone, such conclusions await confirmatory trials.

Abstract
PURPOSE Temozolomide (TMZ) and 13-cis-retinoic acid (cRA) have shown activity in prior single-agent trials of recurrent malignant gliomas (MG). This phase II trial evaluated efficacy and toxicity of combination temozolomide and cRA treatment in recurrent MG. PATIENTS AND METHODS Adults with recurrent supratentorial MG for whom surgery, radiation, and/or chemotherapy failed were eligible. Treatment included oral TMZ 150 or 200 mg/m2/d, days 1 through 5, and cRA 100 mg/m2/d, days 1 to 21, every 28 days. Primary end point was progression-free survival at 6 months (PFS 6); secondary end points included response, survival, and PFS12. RESULTS Eighty-eight eligible patients (glioblastoma multiforme [n = 40]; anaplastic gliomas [n = 48; astrocytoma, 28; oligodendroglioma, 14; mixed glioma, six]) received treatment. PFS 6 was 43% (95% confidence interval [CI], 33% to 54%) and PFS12 was 16% (95% CI, 10% to 26%). Median overall PFS was 19 weeks (95% CI, 16 to 27 weeks), and median overall survival (OS) was 47 weeks (95% CI, 36 to 58 weeks). OS was 46% (95% CI, 36% to 57%) at 52 weeks and 21% (95% CI, 13% to 31%) at 104 weeks. Of 84 assessable patients, there were two (3%) complete responses and eight (12%) partial responses (complete plus partial response, 15%). Among 499 treatment cycles, the most common grade 3/4 events included granulocytopenia (1.8%), thrombocytopenia (1.4%), and hypertriglyceridemia (1.2%). CONCLUSION TMZ and cRA were active, exceeding our 20% thresholds for PFS 6 success, assuming 20% improvement over our previously reported database (glioblastoma multiforme: expected, 30%; observed, 32%; anaplastic glioma: expected, 40%; observed, 50%).

Abstract
Other than nitrosoureas (carmustine and lomustine) and temozolomide, no agents have consistently demonstrated clinically meaningful benefits for patients with gliomas. The active metabolite of irinotecan, 7-ethyl-10-hydroxy camptothecin (SN-38), exhibited promising antitumor effects in preclinical glioma models. Clinical trials using weekly or every 3 weeks dosing of irinotecan have been completed. Toxicity consisted primarily of mild to moderate neutropenia and diarrhea with both schedules, with occasional severe toxicity including one death from neutropenia and infection. Preliminary analyses have suggested imaging responses in 10-15% of patients. Preclinical models and our understanding of the mechanism of action suggest that irinotecan may sensitize glioma cells to the cytotoxic actions of radiation therapy and alkylating agents; clinical trials designed to assess the therapeutic benefit of combination therapy currently are in progress. There is substantial clinical evidence that the concurrent administration of irinotecan with certain anticonvulsants produces reduced exposure to SN-38. In the absence of anticonvulsants, there is also substantial interpatient variability in drug exposure, perhaps reflecting inherited differences in drug metabolism. Finally several mechanisms of tumor cell resistance to irinotecan have been hypothesized, but the clinical significance of these observations has not been confirmed. Correlative studies to address these pharmacokinetic, pharmacogenetic, and drug resistance questions are ongoing.

Abstract
DTI-015 (BCNU in 100% ethanol) utilizes solvent facilitated perfusion for the intratumoral treatment of gliomas. The ethanol solvent vehicle facilitates a rapid and thorough saturation of the tumor with the dissolved anticancer agent BCNU. We conducted a phase I/II dose escalation study of DTI-015 in 40 heavily pretreated patients with inoperable recurrent malignant glioma. The study goals were to establish a maximally tolerated dose (MTD) for DTI-015 and assess its safety and activity. Patients received stereotactic intratumoral injection of DTI-015 under magnetic resonance imaging guidance. Dose escalation was performed in two phases. First, DTI-015 volume was escalated at a set BCNU concentration of 12.5 mg/ml; second, BCNU mg dose was escalated by increasing BCNU concentration to 30, 45, 60, and 75 mg/ml. A MTD of 5 ml and 240 mg was established. Twenty-five of 28 DTI-015 treatments (89%) using </=MTD were administered safely without producing high-grade drug-related adverse events. Median survival for GBM patients administered DTI-015 at </=MTD was 55 weeks. Magnetic resonance imaging demonstrated stable disease in 72% of evaluable patients with a median of 10.5 weeks. The results suggest that DTI-015 administered at </=MTD is well tolerated and active in patients with inoperable recurrent GBM.

Abstract
PURPOSE To determine the response rate of the malignant gliomas of childhood to an oral, daily schedule of temozolomide. PATIENTS AND METHODS A multicenter, phase II evaluation of an oral, daily schedule of temozolomide (200 mg/m(2) on 5 consecutive days) was undertaken in children with relapsed or progressive, biopsy-proven, high-grade glioma (arm A) and progressive, diffuse, intrinsic brainstem glioma (arm B). Evidence of activity was defined by radiologic evidence of a sustained reduction in tumor size on serial magnetic resonance imaging scans. RESULTS Fifty-five patients were recruited (34 to arm A and 21 to arm B) and received 215 cycles of chemotherapy. Grade 3/4 thrombocytopenia was the most frequent toxic event (7% of cycles). Prolonged myelosuppression resulted in significant treatment delays and dose reductions (17% and 22% of cycles, respectively). Two toxic deaths were documented and were related to myelosuppression and sepsis in one patient and pneumonia in a second. The overall (best) response rate was 12% for arm A (95% confidence interval [CI], 3 to 28 in the study cohort, and 2 to 31 for eligible patients) and 5% and 6%, respectively, for arm B (95% CI, 0 to 26 in the study cohort, and 0 to 27 for eligible patients). Stabilization of disease was also documented and was most noteworthy for brainstem gliomas, where two patients achieved both radiologic static disease and discontinued steroid medication. CONCLUSION Despite moderate toxicity, objective response rates to temozolomide have been low, indicating that temozolomide has minimal activity in the high-grade gliomas of childhood.

Abstract
BACKGROUND In the current study, the authors investigated clinical, surgical, and histologic characteristics (covariates) and their interactions in eight previously identified classes of childhood supratentorial neuroglial tumors. The classes resulted from 5 factor score profiles on 703 supratentorial neuroglial tumors in the Childhood Brain Tumor Consortium database. METHODS The Cox proportional models were used to identify class survival covariates. RESULTS Age was found to be a survival covariate only in Class 1, in which older age increased the 5-year survival rate 73% from the first year (0.49) to the tenth year (0.85). A greater amount of tumor removed improved survival in Classes 2 and 4 only. Rosenthal fibers improved survival in Class 2 and overrode the negative effects of high Proliferative factor scores and pleomorphic nuclei. Survival for Class 3 children with high Proliferative factor scores improved from 0.60 to 0.95 as the Spongy factor scores increased. Survival in Class 4 increased from 0.17 to 0.39 with total tumor removal. Irregular nuclei and glomeruloid capillaries improved survival in Class 5 patients. Class 6 survival improved with low cell density. Macrocysts in tumors in Classes 1 and 5 were found to improve survival. CONCLUSIONS As a result of the current study, the authors conclude that survival covariates differ with tumor class and may modify prognosis considerably.

Abstract
BACKGROUND Ependymomas are reported to constitute 4% of all primary central nervous system (CNS) malignancies in adults, 30% of which occur in the spinal cord. A prospective Phase II study to determine toxicity and response to chronic oral etoposide in patients with recurrent low-grade intramedullary spinal cord ependymoma (SCE) was conducted. METHODS Ten patients (6 males and 4 females with a median age of 30 years) with recurrent SCE were treated with oral etoposide (50mg/m(2)/day given daily for 21 days followed by a 14-day break and then repeated constituted a cycle of therapy). All patients had failed surgery and radiotherapy and four patients had failed one prior chemotherapy. Blood counts were obtained weekly, and neurologic examination and a chemistry panel were performed monthly. Contrast-enhanced magnetic resonance imaging of the spine was performed every 8 weeks after a cycle of etoposide and before the next cycle of chemotherapy was initiated. RESULTS Treatment-related complications included alopecia in 9 patients, nonbloody diarrhea in 6 patients, a baseline weight loss of > 10% in 5 patients, Grade (according to the National Cancer Institute Common Toxicity Scale) 3-4 neutropenia in 3 patients, Grade 3-4 thrombocytopenia in 3 patients, and Grade 3-4 anemia in 2 patients. There were no treatment-related deaths reported. After 1 cycle of etoposide, 3 patients (30%) demonstrated progressive disease, 2 patients (20%) achieved a partial response, and 5 patients (50%) maintained stable disease. The overall median response or stable disease duration (disease-free progression) was 15 months (range, 2.5-45+ months). The overall median survival was 17.5 months (range, 3-45+ months). CONCLUSIONS Chronic oral etoposide appears to be well tolerated, has modest toxicity, and had apparent activity in the small cohort of adults in the current study with surgically and medically refractory, recurrent, intradural intramedullary SCE.

Abstract
BACKGROUND Nitrosoureas constitute the main resource of chemotherapy for glioblastoma. However, because of chemoresistance, which is intrinsic or rapidly acquired after the first administration of chemotherapy, there have been few improvements in survival. Because O(6)-alkylguanine-DNA alkyltransferase (AGT) is the main target for increasing cell sensitivity to the nitrosoureas, we postulated that preexposure to other alkylating agents might increase the therapeutic index of the nitrosoureas by saturating all the copies of AGT present in the tumor cells. OBJECTIVE To investigate the response rate, toxic effects, time from start of chemotherapy to progression of disease or exit from the study for any reason (TTP), and progression-free survival at 6 months (PFS-6) associated with a multidrug combination that could reverse resistance to carmustine (BCNU) through AGT depletion. METHODS We conducted a phase 2 study of patients with glioblastoma at first relapse or progression after surgery and standard radiotherapy. Patients were treated with 100 mg/m(2) of procarbazine on days 1 to 5, 80 mg/m(2) of BCNU on days 3 to 5, and 1.4 mg/m(2) of vincristine on day 3 every 8 weeks. RESULTS Fifty-eight patients were enrolled in the study, and all were assessable for response and toxic effects. Six patients (10.3%) had a complete response, 11 (19%) had a partial response, and 17 (29.3%) had stable disease. The median TTP was 4.8 months; 42.3% of patients had PFS-6, and 15.4% had PFS at 12 months. Response to chemotherapy was the only significant prognostic factor for TTP. Neutropenia was grade 3 in 8.6% of patients and grade 4 in 5.2% of patients, and thrombocytopenia was grade 3 in 17.2% of patients and grade 4 in 12% of patients; hepatic and pulmonary toxic effects were grade 3 in 5.2% and 8.6% of patients, respectively. CONCLUSION This regimen proved active in chemotherapy-naive patients with recurrent glioblastoma even though toxic effects were substantial.

Abstract
BACKGROUND Temozolomide, an imidazotetrazine prodrug has shown activity in phase II studies in patients with high-grade glioma at first recurrence. We assessed the efficacy of temozolomide as second-line therapy following failure of PCV chemotherapy in patients with recurrent/progressive gliomas. PATIENTS AND METHODS Between September 1994 and November 2000, 32 patients with high-grade gliomas at second recurrence/progression received temozolomide as salvage therapy and results were reviewed retrospectively. RESULTS Of 32 assessable patients 7 had clinical improvement; there were no imaging responses. Median survival of the cohort was 4 months, with 28% alive at 6 months. Age, performance status, histology and previous response to PCV chemotherapy did not predict for clinical response to temozolomide. CONCLUSION In the small cohort of patients with recurrent malignant glioma who failed PCV chemotherapy temozolomide demonstrated limited activity as second-line treatment although this remains within the confidence intervals of response seen in patients with glioblastoma.

Abstract
This phase II study was designed to evaluate the safety, tolerability, and efficacy of irinotecan (CPT-11) in the treatment of adults with malignant glioma. Patients with progressive or recurrent malignant gliomas were enrolled. CPT-11 was administered as a 90-minute intravenous infusion at a dose of 300 mg/m(2) once a week every 3 weeks. After 2 treatments, doses were increased to 350 mg/m(2) in those patients without grade III/IV toxicities. Dose modifications were made for toxicities. All 14 patients who enrolled (11 males and 3 females) were treated with CPT-11 and were assessable for survival, response, and toxicity. The majority of patients (86%) had prior surgery. Two patients had a confirmed partial response and 2 patients (14%) had stable disease. Median survival was 24 weeks. Median time to tumor progression was 6 weeks. The primary hematologic toxicity was grade III/IV neutropenia, which was observed in 14% of patients. Infrequent grade III/IV nonhematologic toxicity was observed, possibly because of the concomitant use of anticonvulsants, which may have altered pharmacokinetics. These results suggest that CPT-11 has activity against recurrent malignant glioma using a dosing regimen of 300 mg/m(2) every 3 weeks showing limited toxicity. The concurrent use of anticonvulsant medications may have played a role in altering pharmacokinetics and thus the maximum tolerated dose in this patient population.

Abstract
PURPOSE Novel therapies are needed for patients with recurrent glioblastoma multiforme (GBM). Because there is evidence that temozolomide (TMZ) has some activity in GBM and is well tolerated, and because of laboratory evidence that metalloproteinases are important in glioma cell invasion, the combination of TMZ and the matrix metalloproteinase inhibitor marimastat (MRM) in patients with recurrent GBM was studied. PATIENTS AND METHODS Forty-four patients with recurrent GBM after standard radiotherapy were enrolled. For 19 patients, this therapy was their first chemotherapy after tumor progression after irradiation; 25 others had received chemotherapy previously. TMZ 150 to 200 mg/m(2) days 1 to 5 and MRM 50 mg days 8 to 28 was administered at 28-day intervals for two cycles; then patients were reevaluated. Treatment continued until progression of tumor or toxicity developed. RESULTS Joint and tendon pain was the major therapy-related toxicity and was reported in 47% of patients. Five patients (11%) were removed from the study because of intolerable joint pain. For all patients, the progression-free survival (PFS) at 6 months was 39%. Median PFS was 17 weeks, median overall survival was 45 weeks, and 12-month PFS was 16%. CONCLUSION The combination of TMZ and MRM resulted in a PFS at 6 months that exceeded the literature target by 29%. This drug combination met phase II study criteria; further study in recurrent patients with GBM might be warranted. Further study of therapy-induced joint pain is necessary.

Abstract
PURPOSE To assess the efficacy and toxicity of intraresection cavity (131)I-labeled murine antitenascin monoclonal antibody 81C6 and determine its true response rate among patients with newly diagnosed malignant glioma. PATIENTS AND METHODS In this phase II trial, 120 mCi of (131)I-labeled murine 81C6 was injected directly into the surgically created resection cavity of 33 patients with previously untreated malignant glioma (glioblastoma multiforme [GBM], n = 27; anaplastic astrocytoma, n = 4; anaplastic oligodendroglioma, n = 2). Patients then received conventional external-beam radiotherapy followed by a year of alkylator-based chemotherapy. RESULTS Median survival for all patients and those with GBM was 86.7 and 79.4 weeks, respectively. Eleven patients remain alive at a median follow-up of 93 weeks (range, 49 to 220 weeks). Nine patients (27%) developed reversible hematologic toxicity, and histologically confirmed, treatment-related neurologic toxicity occurred in five patients (15%). One patient (3%) required reoperation for radionecrosis. CONCLUSION Median survival achieved with (131)I-labeled 81C6 exceeds that of historical controls treated with conventional radiotherapy and chemotherapy, even after accounting for established prognostic factors including age and Karnofsky performance status. The median survival achieved with (131)I-labeled 81C6 compares favorably with either (125)I interstitial brachy-therapy or stereotactic radiosurgery and is associated with a significantly lower rate of reoperation for radionecrosis. Our results confirm the efficacy of (131)I-labeled 81C6 for patients with newly diagnosed malignant glioma and suggest that a randomized phase III study is indicated.

Abstract
A rapid and systematic review of the effectiveness and cost-effectiveness of temozolomide in the treatment of recurrent malignant glioma was commissioned by the NHS HTA Programme on behalf of NICE. The full report has been published elsewhere. This paper summarizes the results for the effectiveness of temozolomide in people with recurrent glioblastoma multiforme and anaplastic astrocytoma. The review was conducted using standard systematic review methodology involving a systematic literature search, quality assessment of included studies with systematic data extraction and data synthesis. One randomized controlled trial and four uncontrolled studies were identified for inclusion. The key results were that temozolomide may increase progression-free survival but has no significant impact on overall length of survival. The main effect from temozolomide may have been in those patients who had not received any prior chemotherapy regimens, however further randomized controlled trials are required to confirm this suggestion. Temozolomide appears to produce few serious adverse effects and may also have a positive impact on health-related quality of life. Overall the evidence-base is weak and few strong conclusions can be drawn regarding the effectiveness of temozolomide. Large, well-designed randomized controlled trails conducted in a wider patient population are needed.

Abstract
BACKGROUND A prospective Phase II study of CPT-11 in adult patients with recurrent supratentorial glioblastoma multiforme (GBM). METHODS Forty patients (25 men, 15 women) ages 32-71 years (median 59), with recurrent GBM were treated. All patients had previously been treated with surgery and involved field radiotherapy (median dose 60 Gy; range 59-60). Additionally, all patients were treated with adjuvant chemotherapy (BCNU in 20, PCV in 18, Procarbazine in 2). Twenty-five patients (62%) were on anticonvulsants (phenytoin in 15, carbamazepine in 10) and 26 patients (65%) were on dexamethasone. Recurrent disease was defined by neuroradiographic disease progression (>25% increase in tumor dimensions) using gadolinium-enhanced MR imaging. The starting dose of CPT-11 was 400 mg/m2 followed in three weeks by 500 mg/m2, operationally defined as one cycle. At week 6, all patients were evaluated with MRI and neurological examination. RESULTS All patients were evaluable. Two doses (one cycle) of CPT-11 were administered to all patients. CPT-11-related toxicity included: diarrhea (16 patients, 40%); thrombocytopenia (9 patients, 23%); and neutropenia (6 patients, 15%). No patient required transfusion nor was treatment for neutropenic fever required. No treatment-related deaths were observed. All patients demonstrated progressive disease following one cycle of CPT-11. CONCLUSIONS The lack of response to CPT-11 in this patient group with recurrent GBM suggests either CPT-11 has minimal activity or CPT-11 doses/schedule utilized in this study were sub-optimal. The latter is supported by the modest toxicity seen in this study and the previously documented enhanced clearance of CPT-11 in patients on anticonvulsants and dexamethasone.

Abstract
Recurrent and progressive non-GBM gliomas are a diverse group of brain tumors that often respond poorly to adjuvant chemotherapy treatment. Regional intra-arterial (IA) administration of chemotherapy may result in increased tumor uptake of drug, with improvement in response rates and time to progression (TTP). Twenty-five patients with recurrent or progressive non-GBM gliomas were treated with IA carboplatin (200 mg/m2/d) and intravenous (IV) etoposide (100 mg/m2/d) for 2 days every 4 weeks. Patients ranged in age from 22 to 68 years (mean 37.8). All but one patient had received standard irradiation, and eight patients had attempted prior chemotherapy. Five of 25 patients had objective responses (20%), while another 15 patients had stable disease (60%), receiving a total of 318 IA treatment procedures. There was one complete response (4.0%), three partial responses (12.0%), one minor response (4.0%), 15 stable diseases (60.0%), and five progressive diseases (20.0%). The median TTP was 24.2 weeks overall and 32 weeks in responders. Overall median survival was 34.2 weeks. Therapy was well tolerated, with mainly hematologic toxicity. Two patients had embolic complications. Although these are preliminary results, IA carboplatin and IV etoposide have modest activity against recurrent and progressive non-GBM gliomas and warrants further study.

Abstract
Clinical trials are prospective scientific studies involving human participants and form the basis for identifying new treatments for diseases like brain tumors. A clinical trial should be designed to provide definitive results for a study question. Therefore, investigators should understand the principles underlying the design, execution and analysis of clinical trials. In addition to the application of basic principles germane to the design of all clinical trials, studies in neuro-oncology also involve unique challenges in case definition, selection of endpoints and definition of response. This review begins with enumeration of the basic principles of clinical trial design including reduction of bias and variability, and concludes with a review of study design factors of particular relevance for neuro-oncology.

Abstract
In reviewing the numerous investigational drug trials for patients with anaplastic gliomas over the past 20 years, it would be fair to say that there have been more than a few disappointments and that the real impact of many of these therapies on patients' duration and quality of survival has been minor at best. It is also fair to state that there has been progress in developing new types of chemotherapy and other agents, in devising new treatment strategies, and in gaining a deeper understanding of the problems that must be overcome to treat patients with anaplastic gliomas successfully. The past several years have seen the realization that oligodendroglioma, primary CNS lymphoma, and medulloblastoma are sensitive to chemotherapy treatments. It is hoped that future studies will delineate better the optimal use of chemotherapy for these tumors.

Abstract
BACKGROUND Resistance to chemotherapeutic agents and poor blood-brain barrier penetration are major limitations in the treatment of malignant glioma. To improve drug delivery across the blood-brain barrier, the authors used doxorubicin as liposomal encapsulated formulation (Caelyx, Scheringh-Plough, Munich, Germany) in therapy of recurrent malignant glioma. METHODS Fifteen patients with recurrent high-grade gliomas were included in the study. Of these, 13 patients could be evaluated, including 6 patients with glioblastoma, 1 patient with gliosarcoma and 6 patients with anaplastic astrocytoma. The treatment consisted of liposomal doxorubicin (20 mg/m(2)), applied intravenously every 2 weeks. RESULTS Stabilization of the disease was observed in 54% (7 of 13) of patients. Partial response and complete response (CR) were not observed. Median time-to-progression was 11 weeks. Progression free survival at 12 months was 15%. Median overall survival (OS) after doxorubicin therapy was 40.0 weeks, whereas the median OS after diagnosis reached 20.0 months (87.0 weeks). Doxorubicin was well tolerated, with main side effects being palmoplantar erythrodysesthesia occurring in 38% and myelotoxicity (World Health Organization Grade 3-4) in 31% of the patients. CONCLUSIONS Doxorubicin has been shown to be a safe treatment with moderate activity that may lead to long-term stabilization in recurrent high-grade glioma patients. Of note, median OS after all and after initiation of recurrence therapy was prolonged in comparison with the OS in other Phase II studies, as recently described by Wong et al. (Wong ET, Hess KR, Gleason MJ, Jaeckle KA, Kyritsis AP, Prados MD, et al. Outcomes and prognostic factors in recurrent glioma patients enrolled onto phase II clinical trials.

Abstract
Temozolomide has an evolving role in the treatment of high grade gliomas. Recent studies suggest that temozolomide is well tolerated and efficacious. This study retrospectively analysed the activity and toxicity associated with temozolomide at two Australian centres over a 24 month period. Fifty-six patients with recurrent high grade gliomas were treated with temozolomide. Patients received temozolomide orally at 150-200mg/m(2)daily, days 1-5, every 4 weeks. The median number of treatment cycles was 4 (1-12). Of the 56 patients, 15 (27%) achieved complete or partial response and 18 (32%) achieved minor response or stable disease. There were no episodes of febrile neutropenia and temozolomide was generally well tolerated. In conclusion, temozolomide is an active therapy in patients with recurrent high grade glioma and our results concord with published studies.

Abstract
The management of patients with anaplastic astrocytoma (AA) requires multidisciplinary involvement. In this article, the literature on the treatment of patients with AA is reviewed, emphasizing randomized trials and key retrospective studies. The role of surgery, radiation therapy, and chemotherapy in newly diagnosed patients and those with recurrent disease is described. Basic science insights, advances in neuroimaging and neuropathology, and novel therapies targeting invasion, angiogenesis, and growth modulation will hopefully lead to improved outcome in this subset of patients with malignant glioma.

Abstract
Chronic oral VP-16 (etoposide) is a chemotherapy regimen with a wide application in oncology and documented efficacy against germ cell tumors, lymphomas, Kaposi's sarcoma, and primary brain tumors. This study was performed to assess the toxicity and activity of chronic oral etoposide in the management of children with recurrent intracranial nondisseminated ependymoma. Twelve children (median age of 8 years) with recurrent ependymoma who were refractory to surgery, radiotherapy, and chemotherapy (carboplatinum or the combination of procarbazine, lomustine, and vincristine) were treated with chronic oral etoposide (50 mg/m(2)/day). Treatment-related complications included the following: alopecia (10 children), diarrhea (6), weight loss (5), anemia (4), neutropenia (3), and thrombocytopenia (3). Three children required transfusion (two with packed red blood cells; two with platelets), and two children developed neutropenic fever. No treatment-related deaths occurred. Six children (50%) demonstrated either a radiographic response (two children, both with partial response) or stable disease (four children) with a median duration of response or stable disease of 7 months. In this small cohort of children with recurrent intracranial ependymoma, oral etoposide was well tolerated, produced modest toxicity, and had apparent activity.

Abstract
Retreatment of malignant gliomas may be performed with palliative intent after careful consideration of the risks and benefits, and with special regards to iatrogenic neurotoxicity and quality of life (QOL). This review compares studies of several retreatment strategies (published between 1987 and 2000) based on the quality of their evidence. Depending on both established prognostic factors and previous treatment, individually tailored retreatment strategies are possible. In all studies that included a multivariate analysis of prognostic factors, performance status was the most important. So far, predictive factors for response, which might facilitate patient selection, have not been unequivocally defined. In terms of QOL, single-agent chemotherapy (temozolomide, nitrosoureas, platinum and taxane derivatives) may offer a better therapeutic ratio than polychemotherapy. For glioblastoma multiforme, progression-free survival and QOL were more favourable after temozolomide than procarbazine (level 1 evidence). The survival of patients after various radiotherapy techniques is broadly similar. However, considerable toxicity is associated with radiosurgery or brachytherapy. Fractionated stereotactic radiotherapy plus radio-sensitizing cytostatic agents has shown promising initial results in small groups of selected patients and awaits further evaluation. Level 2 evidence derived from non-randomized studies does not suggest a substantial prolongation of survival by re-resection as compared with chemotherapy or radiotherapy alone. Level 1 evidence derived from a randomized trial suggests that application of BCNU polymers significantly improves the outcome after re-resection. However, most studies reported median survival in the range of only 25-35 weeks, thereby emphasizing the need for the development and clinical evaluation of new innovative treatment approaches.

Abstract
This is a review of chemotherapy options for patients with brain tumors, both at the time of initial diagnosis and at recurrence. Gliomas, the most common malignant brain tumors, represent the main focus of the review; chemotherapeutic options for supratentorial, brain stem, and optic track gliomas are discussed.

Abstract
Treosulfan is a bifunctional alkylating prodrug with activity against various solid tumors. To improve the outcome for patients with recurrent malignant glioma, we assessed the efficacy of intravenous treosulfan (6-10 g/m2 4-weekly) as salvage therapy for patients with recurrent or progressive glioblastoma (GB, n = 14) or anaplastic astrocytoma (AA, n = 2). All patients had prior involved-field radiotherapy and adjuvant nitrosourea-based chemotherapy. A total of 56 cycles were administered. Tumor responses were assessed radiologically and clinically prior to each cycle. All patients were assessable for toxicity, response and survival. There were no complete or partial responses (CR, PR). Two patients progressed after the first cycle, 14 patients had initially stable disease (SD). Median progression-free survival was 3.25 months for the GB patients. Five patients were progression-free at 6 months (30%), including the 2 AA patients. The 2 AA patients are stable at 22 months. Myelosuppression was the dose-limiting toxicity in this cohort of nitrosourea-pretreated patients. Treosulfan has modest activity in patients with recurrent malignant glioma. Further evaluation of treosulfan in chemonaive malignant glioma patients is warranted.

Abstract
Taxol has activity in the treatment of high grade gliomas but estramustine phosphate (EMP) has not been used in this setting. In vitro data demonstrates that EMP is cytotoxic to glioma cell lines and estramustine binding proteins are expressed by glioma cells. The combination of Taxol and EMP is reported to be active in the treatment of hormone-refractory prostate cancer and in taxane-resistant breast and ovarian cancer. We therefore performed a phase II study to assess the activity and toxicity of this combination in high grade gliomas. Taxol was given at a dose of 225 mg/m2 intravenously over three hours on day 1 and EMP was given at a dose of 900 mg/m2 orally on days 1 through 3. Cycles were repeated every three weeks. Twenty patients with recurrent glioblastoma multiforme (GBM) were enrolled: 11 male, median age 45 years. All patients received anti-epileptic medications and 17 (80%) had received prior chemotherapy. Of 18 evaluable patients, two had partial responses (11) and six had stable disease (33%) for a minimum of eight weeks. Treatment was well tolerated with grade 3 neutropenia occurring in only three patients. There were no other grade 3 or 4 toxicities. The median time to progression for the cohort was only six weeks (range 3-60+ weeks). The median overall survival was 12 weeks (range 3-60+ weeks). In conclusion, the combination of Taxol and EMP is well tolerated and has modest activity in the treatment of recurrent GBM.
