Safety and efficacy of concurrent interstitial radiation and hyperthermia in the treatment of progressive malignant brain tumors

High activity 125I brachytherapy has efficacy in selected recurrent malignant brain tumors, but limited efficacy and risk of radiation necrosis have prompted investigation of additional adjunctive therapies. This study aims to assess the toxicity of interstitial conductive hyperthermia used concurrently with 125I brachytherapy for the treatment of recurrent brain malignancies. Twelve patients with recurrent malignant brain tumors were implanted using afterloading catheters intended to deliver 50 Gy at the isodose line encompassing the enhancing tumor with a 5-mm margin and heated to 41.5 degrees C for 48 h. The average implant volume was 18 cc with 5.3 catheters containing 9.4 sources with a total activity of 265 mCi. Serious toxicities included 8 motor deficits, 2 mood alterations, 4 seizures and 2 catheter wound cerebrospinal fluid leaks. Median survival was 10.35 months with the best responses being 6 with stable disease and 2 with partial responses. Reoperation rate for radiation necrosis was 33%. Concurrent conductive thermoradiotherapy is feasible but is associated with serious toxicity. There is no suggestion of improved survival with thermoradiotherapy over brachytherapy alone. Given the degree of toxicity observed, alternative approaches to improving local control of these tumors are being explored.     

Permanent iodine 125 brachytherapy in patients with progressive or recurrent glioblastoma multiforme

This study reports the initial experience at the University of California San Francisco (UCSF) with tumor resection and permanent, low-activity iodine 125 (125I) brachytherapy in patients with progressive or recurrent glioblastoma multiforme (GM) and compares these results to those of similar patients treated previously at UCSF with temporary brachytherapy without tumor resection. Thirty-eight patients with progressive or recurrent GM were treated at UCSF with repeat craniotomy, tumor resection, and permanent, low-activity 125I brachytherapy between June 1997 and May 1998. Selection criteria were Karnofsky performance score > or =60, unifocal, contrast-enhancing, well-circumscribed progressive or recurrent GM that was judged to be completely resectable, and no evidence of leptomeningeal or subependymal spread. The median brachytherapy dose 5 mm exterior to the resection cavity was 300 Gy (range, 150-500 Gy). One patient was excluded from analysis. Median survival was 52 weeks from the date of brachytherapy. Age, Karnofsky performance score, and preimplant tumor volume were all statistically significant on univariate analyses. Multivariate analysis for survival showed only age to be significant. Median time to progression was 16 weeks. Both univariate and multivariate analysis of freedom from progression showed only preoperative tumor volume to be significant. Comparison to temporary brachytherapy patients showed no apparent difference in survival time. Chronic steroid requirements were low in patients with minimal postoperative residual tumor. We conclude that permanent 125I brachytherapy for recurrent or progressive GM is well tolerated. Survival time was comparable to that of a similar group of patients treated with temporary brachytherapy.     

Phase II study of high central dose Gamma Knife radiosurgery and marimastat in patients with recurrent malignant glioma

: To assess the outcome of high central dose Gamma Knife radiosurgery plus marimastat in patients with recurrent malignant glioma.

: Twenty-six patients with recurrent malignant glioma were enrolled in a prospective Phase II study between November 1996 and January 1999. The radiosurgery dose was prescribed at the 25–30% isodose surface to increase the dose substantially within the tumor’s presumably hypoxic core. Marimastat was administered after radiosurgery to restrict regional tumor progression. Survival was compared with that of historical patients treated at our institution with standard radiosurgery.

: The median times to progression after radiosurgery for Grade 3 and 4 patients was 31 and 15 weeks, respectively. The corresponding median survival time after radiosurgery was 68 and 38 weeks. The median survival time after radiosurgery in the historical patients was 59 and 44 weeks.

: The dual strategies of using high central dose radiosurgery to overcome tumor hypoxia together with marimastat to inhibit local tumor invasion may offer a small survival advantage for recurrent Grade 3 tumors; they do not offer an advantage for recurrent Grade 4 tumors.     

Outcomes and prognostic factors in recurrent glioma patients enrolled onto phase II clinical trials.

PURPOSE: To determine aggregate outcomes and prognostic covariates in patients with recurrent glioma enrolled onto phase II chemotherapy trials. PATIENTS AND METHODS: Patients from eight consecutive phase II trials included 225 with recurrent glioblastoma multiforme (GBM) and 150 with recurrent anaplastic astrocytoma (AA). Their median age was 45 years (range, 15 to 82 years) and their median Karnofsky performance score was 80 (range, 60 to 100). Prognostic covariates were analyzed with respect to tumor response, progression-free survival (PFS), and overall survival (OS) by multivariate logistic and Cox proportional hazards regression analyses. RESULTS: Overall, 34 (9%) had complete or partial response, whereas 80 (21%) were alive and progression-free at 6 months (APF6). The median PFS was 10 weeks and median OS was 30 weeks. Histology was a robust prognostic factor across all outcomes. GBM patients had significantly poorer outcomes than AA patients. The APF6 proportion was 15% for GBM and 31% for AA, whereas the median PFS was 9 weeks for GBM and 13 weeks for AA. Results were also significantly poorer for patients with more than two prior surgeries or chemotherapy regimens. CONCLUSION: Histology is a dominant factor in determining outcome in patients with recurrent glioma enrolled onto phase II trials. Future trials should be designed with separate histology strata.     

Salvage chemotherapy with cyclophosphamide for recurrent temozolomide-refractory anaplastic astrocytoma

BACKGROUND: A prospective Phase II study of cyclophosphamide (CYC) was conducted in adult patients with recurrent temozolomide-refractory anaplastic astrocytoma (AA) with a primary objective of evaluating 6-month progression-free survival (PFS). METHODS: Forty patients (28 men, 12 women) ages 26-57 years (median, 43 yrs) with neuroradiographically recurrent AA were treated. All patients had previously been treated with surgery and involved-field radiotherapy. Additionally, all patients were treated with temozolomide (TMZ) chemotherapy after radiotherapy. All patients were treated at recurrence with CYC administered intravenously on 2 consecutive days (750 mg/m2/day) every 4 weeks (operationally defined as a single cycle). Neurologic and neuroradiographic evaluation were performed every 8 weeks. RESULTS: All patients were evaluable. A total of 215 cycles of CYC (median, 4 cycles; range 2-12 cycles) was administered. CYC-related toxicity included alopecia (all patients, 100%), anemia (5, 12.5%), thrombocytopenia (6, 15%), and neutropenia (8, 20%). Four (10%) patients required transfusion. Nine patients (22.5%) (95% confidence interval [95% CI], 11%-39%) demonstrated a neuroradiographic partial response, 16 patients (40.0%) (95% CI, 25%-57%) demonstrated stable disease, and 15 patients (37.5%) (95% CI, 23%-54%) had progressive disease after 2 cycles of CYC. Time to tumor progression ranged from 2-19 months (median, 4 mos; 95% CI, 2-6 mos). Survival ranged from 2-26 months (median, 8 mos; 95% CI, 6-10 mos). The 6-month and 12-month PFS was 30% and 8%, respectively. CONCLUSIONS: CYC demonstrated modest efficacy with acceptable toxicity in this cohort of adult patients with recurrent anaplastic astrocytoma, all of whom had failed prior TMZ chemotherapy.     

Preliminary results in heavy charged particle irradiation of bone sarcoma.

Between 1979 and 1989, 17 patients with unfavorable bone sarcoma were treated wholly or in part with heavy charged particle irradiation (helium and/or neon ions) at the University of California Lawrence Berkeley Laboratory. The majority of tumors were located near critical structures such as the spinal cord or brain. Gross tumor was present in all but two patients at the time of irradiation. Six patients were treated for recurrent disease. Histologies included osteosarcoma, Ewing's sarcoma, and recurrent osteoblastoma. Four of the osteosarcomata were believed to have been induced by previous therapeutic irradiation for various tumors. Follow-up time since initiation of radiation ranged from 7 to 118 months (median 40 months). The 5-year Kaplan-Maier local control rate was 48%; the corresponding survival rate was 41%. Over half the patients succumbed to distant metastases despite the majority of patients receiving chemotherapy. In this preliminary study, we have shown that heavy charged particle irradiation can be effectively used for control of bone sarcoma. A Phase II trial is warranted to determine optimal treatment for unresectable or gross residual disease.     

Results of interstitial brachytherapy for malignant brain tumors

We evaluated the efficacy of brachytherapy in patients with malignant brain tumors and assessed the factors associated with longer disease control after treatment. From June 1989 to October 1995, 73 patients were treated with stereotactic brachytherapy with temporary placement of iodine-125 implants. The median age was 52 (range 9-79). Median KPS was 80. There were 48 patients with a glioblastoma multiforme, 13 with an anaplastic astrocytoma, and 12 with other tumors. Of the 67 evaluable patients, 20 underwent brachytherapy as part of the therapy for a newly diagnosed tumor (17 were glioblastomas) and 46 had brachytherapy at the time of progression (28 were glioblastomas). Median survival time for all patients undergoing brachytherapy from diagnosis was 70.3 weeks. Median survival from implant was 39.3 weeks. For patients with an anaplastic astrocytoma, median survival from diagnosis and implant was 158.1 and 36.9 weeks respectively. For patients with a glioblastoma multiforme, median survival from diagnosis and implant was 62.9 and 37.1 weeks respectively. Eleven patients (16%) developed radiation necrosis. Nine patients (13%) developed other complications. Age and histologic diagnosis were significant predictors of survival from diagnosis. Age and KPS were independent predictors of time to failure after implant. Certain characteristics, specifically younger age (<55), and a higher KPS (相似文献   

Treatment of malignant gliomas with interstitial irradiation and hyperthermia.

A Phase I study of interstitial thermoradiotherapy for high-grade supratentorial gliomas has been completed. The objective of this trial was to test the feasibility and toxicity of hyperthermia induced by ferromagnetic implants in the treatment of intracranial tumors. The patient population consisted of 16 males and 12 females, with a median age of 44 years and a median Karnofsky score of 90. Nine patients had anaplastic astrocytoma while 19 had glioblastoma multiforme. Twenty two patients were treated at the time of their initial diagnosis with a course of external beam radiotherapy (median dose 48.4 Gy) followed by an interstitial implant with Ir-192 (median dose 32.7 Gy). Six patients with recurrent tumors received only an interstitial implant (median dose 40 Gy). Median implant volume for all patients was 55.8 cc and median number of treatment catheters implanted per tumor was eighteen. A 60-minute hyperthermia treatment was given through these catheters just before and right after completion of brachytherapy. Time-averaged temperatures of all treatments were computed for sensors located within the core of (> 5 mm from edge of implant), and at the periphery of the implant (outer 5 mm). The percentage of sensors achieving an average temperature > 42 degrees C was 61% and 35%, respectively. Hyperthermia was generally well tolerated; however, there have been 11 minor toxicities, which resolved with conservative management, and one episode of massive edema resulting in the death of a patient. In addition, there were three major complications associated with the surgical implantation of the catheters. Preliminary survival analysis shows that 16 of the 28 patients have died, with a median survival of 20.6 months from diagnosis. We conclude that interstitial hyperthermia of brain tumors with ferromagnetic implants is feasible and carries significant but acceptable morbidity given the extremely poor prognosis of this patient population.     

Brachytherapy of glioblastoma recurring in previously irradiated territory: predictive value of tumor volume

PURPOSE: To evaluate the impact of tumor volume on survival of patients reirradiated with (192)Ir for recurrent glioblastoma. METHODS AND MATERIALS: Between 1993 and 1997, 42 patients with recurrent glioblastomas (29 males and 13 females, age 18-69 years, median age 49) were treated with (192)Ir implantation. Previous treatments included surgery, external beam radiotherapy, and chemotherapy. Maximum diameter of the recurrent tumor was 1.2-10.1 cm (median: 5.7 cm) and tumor volume was 1.6-122 cm(3) (median: 23 cm(3)). Karnofsky performance status score was 50-100 (median: 80). Brachytherapy dose was 40-60 Gy. RESULTS: Probability of overall survival was 80% at 6 months, 48% at 1 year, and 11% at 2 years. Median survival was 50 weeks. Univariate analysis showed that both tumor volume (T < or T > or = 30 cm(3)) and Karnofsky performance status score were significant predictors of survival. Multivariate analysis showed that smaller tumor volumes were associated with a higher probability of survival (p < 0.001). CONCLUSION: Tumor volume less than 30 cm(3) was associated with a higher probability of, and quality of, survival than larger lesions for patients reirradiated by brachytherapy for recurrent glioblastoma.     

Definitive radiotherapy for carcinoma of the vagina: Outcome and prognostic factors

: Primary carcinoma of the vagina is an uncommon tumor. Because of the long-standing interest in this disease at our institution a substantial number of patients with this disease has been accumulated, and this retrospective review was performed to define disease outcome, to delineate significant prognostic factorsm and to provide treatment guidelines. : This was a retrospective review of 301 patients with vaginal carcinoma (271 with squamous cell and 30 with adenocarcinoma) who received definitive radiotherapy between 1953 and 1991. Prognostic factors for outcome (local control, pelvic control, metastatic relapse, survival, and complications) were evaluated using univariate and multivariate techniques. : Patients disease was staged using the International Federation of Gynecology and Obstetrics (FIGO) system, and stages were distributed as follows: 0, 37 (12%); I, 65 (22%); II, 122 (40%); III, 60 (20%); and IVA, 17 (6%). Treatment varied according to stage, with brachytherapy predominating for early disease by external beam playing a prominent role for more advanced disease. Patients with in situ disease received brachytherapy alone ot transvaginal orthovoltage irradiation. FOr Stage I, brachytherapy alone was used in 25, external beam and brachytherapy in 38, and transvaginal alone in 2. For Stage II, brachytherapy alone was used in 20, external and brachytherapy in 66, and external irradiation alone in 36. For stage III, external and brachytherapy was used in 15, and external alone in 45. Two patients with Stage IVA received brachytherapy alone, 10 received a combination of external and brachytherapy, and 6 received external irradiation alone. Total doses ranged from 10 to 154 Gy (mean 74.7 Gy, median 70.0 Gy), but only 18 (6%) received less than 55 Gy. At a median follow-up of 13 yearsm the 5-, 15-, 20-, ans 25-year survival rates were 60%, 49%, 38%, and 23%, respectively. Beyond 5 years the survival rates relative to those for age-matched females in the general population were between 50 and 65%. Actuarial local recurrence rates were 23%, and 26% at 5, 10, and 15 years. Actuarial pelvic relapse rates were 26%, 30% and 31% at 5, 10, and 15 years, and metastatic rates at those times were 15%, 18%, and 18%. Adenocarcinoma (nonclear cell) was a significantly worse disease than squamous cell carcinoma. The major determinants of local control for squamous carcinoma were tumor bulk (specified by size in centimeters, or by FIGO stage), tumor site (upper lesions faring better than other), and tumor circumferential location (lesions involving the posterior wall faring worse). Tumor bulk was an important determinant of metastatic relapse, but failure to acieve local control was also an independently significant determinant of metastases. Salvage after forst relapse was uncommon and the survival rate at 5 years after relapse was only 12%. Serious complictions occured in 39 patients with an actuarial incidence of 19% at 20 years. : Vaginal carcinoma poses a formidable therapeutic challenge. The disease is heterogeneous with respect to its prognostic factors. Nonclear cell adenocarcinoma has an extremely poor prognosis and should be distinguished from squamois carcinoma. Both external beam and brachytherapy play crucial roles in management and most patients with disease beyond in situ should receive a significant component of external irradiation prior to brachytherapy.     

Interstitial brachytherapy in malignant gliomas

Interstitial brachytherapy is a logical and attractive treatment for brain tumors. The ability to irradiate the tumor along with only a limited volume of surrounding brain and the increased therapeutic ratio allow the delivery of higher initial radiation doses and permit reirradiation of tumors that recur after conventional irradiation. The recent availability of CT-directed stereotaxic systems makes it possible to implant high activity iodine-125 sources into brain tumor target with great precision. The median survival of patients with recurrent malignant gliomas treated by brachytherapy was 74 weeks, which was longer than that of 36 weeks treated by chemotherapy.     

Radiotherapy plus concurrent and adjuvant procarbazine, lomustine, and vincristine chemotherapy for patients with malignant glioma

We analyzed the clinical efficacy and toxicity of concurrent therapy as a first line modality for malignant glioma patients. From 1998 to 2004, 39 patients, 22 with glioblastoma (GM), nine with anaplastic astrocytoma (AA), 7 with anaplastic oligodendroglioma (AO) and 1 with anaplastic oligodendro-astrocytoma (AOA) were enrolled in this study. The median age was 46.2 years (range 8-67). Both external involved field radiotherapy and chemotherapy, composed of CCNU (75-110 mg/m(2)), procarbazine (60 mg/m(2)) and vincristine (1.4 mg/m(2)), were started simultaneously two weeks after surgery. The median progression-free survival time for the GM, AA, and AO patients was 6, 26, and 31 months, respectively. The median survival of the patients with GM and AA was 27 and 41 months. The two-year survival rate of the GM and AA patients was 50.4 and 66.7%, respectively. Grade III/IV hematological toxicity was reduced from 25.6 to 13% after reduction of the dose of CCNU (75 mg/m(2)). Radiation necrosis was confirmed by pathologic examination in four patients (10.3%). The median interval from the completion of radiotherapy to the diagnosis of necrosis was 19 weeks. Modified concurrent chemoradiotherapy may be a feasible option for treating malignant glioma with acceptable toxicity.     

Phase I/II clinical trial of carbon ion radiotherapy for malignant gliomas: combined X-ray radiotherapy, chemotherapy, and carbon ion radiotherapy

PURPOSE: To report the results of a Phase I/II clinical trial for patients with malignant gliomas, treated with combined X-ray radiotherapy (XRT), chemotherapy, and carbon ion radiotherapy (CRT). METHODS AND MATERIALS: Between October 1994 and February 2002, 48 patients with histologically confirmed malignant gliomas (16 anaplastic astrocytoma (AA) and 32 glioblastoma multiforme (GBM) were enrolled in a Phase I/II clinical study. The treatment involved the application of 50 Gy/25 fractions/5 weeks of XRT, followed by CRT at 8 fractions/2 weeks. Nimustine hydrochloride (ACNU) were administered at a dose of 100 mg/m(2) concurrently in weeks 1, 4, or 5 of XRT. The carbon ion dose was increased from 16.8 to 24.8 Gray equivalent (GyE) in 10% incremental steps (16.8, 18.4, 20.0, 22.4, and 24.8 GyE, respectively). RESULTS: There was no Grade 3 or higher acute reaction in the brain. The late reactions included four cases of Grade 2 brain morbidity and four cases of Grade 2 brain reaction among 48 cases. The median survival time (MST) of AA patients was 35 months and that of GBM patients 17 months (p = 0.0035). The median progression-free survival and MST of GBM showed 4 and 7 months for the low-dose group, 7 and 19 months for the middle-dose group, and 14 and 26 months for the high-dose group. CONCLUSION: The results of combined therapy using XRT, ACNU chemotherapy, and CRT showed the potential efficacy of CRT for malignant gliomas in terms of the improved survival rate in those patients who received higher carbon doses.     

Salvage chemotherapy with bevacizumab for recurrent alkylator-refractory anaplastic astrocytoma

A retrospective study of bevacizumab only in adults with recurrent temozolomide (TMZ)-refractory anaplastic astrocytoma (AA) with a primary objective of determining progression free survival (PFS). There is no standard therapy for alkylator-resistant AA and hence a need exists for new therapies. Twenty-five patients (15 men; 10 women) ages 26–63 (median 50), with radiographically recurrent AA were treated. All patients had previously been treated with surgery, involved-field radiotherapy, and alkylator-based chemotherapy. Fourteen patients underwent repeat surgery. Patients were treated at second recurrence with bevacizumab (10 mg/kg), once every 2 weeks (defined as a single cycle). Neurological evaluation was performed every 2 weeks and neuroradiographic assessment following the initial two cycles of bevacizumab and subsequently after every four cycles of bevacizumab. All patients were evaluable for toxicity and response. A total of 360 cycles of bevacizumab (median 14 cycles; range 2–40) was administered. Bevacizumab-related toxicity included fatigue (14 patients; 2 grade 3), leukopenia (7; 1 grade 3), deep vein thrombosis (5; 2 grade 3), hypertension (5; 1 grade 3), anemia (4; 0 grade 3) and wound dehiscence (1; 1 grade 3). Sixteen patients (64%) demonstrated a partial radiographic response, 2 (8.0%) stable disease and 7 (28%) progressive disease following two cycles of bevacizumab. Time to tumor progression ranged from 1 to 20 months (median: 7). Survival ranged from 2 to 23 months (median: 9.0). 6-month and 12-month PFS were 60 and 20%, respectively. Bevacizumab demonstrated efficacy and acceptable toxicity in this cohort of adults with recurrent alkylator refractory AA.     

Stereotactic Radiosurgery and Interstitial Brachytherapy for Glial Neoplasms

The application of focal radiation therapies in the management of malignant gliomas has gone through a number of stages. Earlier efforts to improve local control of malignant gliomas involved the use of brachytherapy. Despite some early encouraging results, Phase 3 studies did not prove a significant survival benefit for the addition of brachytherapy for newly diagnosed glioblastoma. Most recently radiosurgery has been employed using the same rationale in that improved local control may improve survival. Results of the RTOG Phase 3 study are pending final publication, but early abstracted reports are negative. While radiosurgery and brachytherapy continue to be used as a form of therapy for selected patients with recurrent gliomas, new information from metabolic imaging studies suggests our problem with these techniques in part may be related to targeting. This paper reviews the recent literature and results of the use of brachytherapy and radiosurgery in the management of newly diagnosed and recurrent malignant gliomas.

Fast neutrons and misonidazole for malignant astrocytomas

Twenty-five patients with biopsy proven malignant supratentorial astrocytomas were entered into a Phase I/II study of misonidazole combined with neutron radiation at Fermilab Neutron Therapy Facility (NTF) between August 1979 and April 1981. The main objectives were to determine tissue tolerance in terms of acute and late effects, and to estimate tumor clearance and survival rates. The total dose was 18.0 Gy given in weekly fractions of 3.0 Gy over 39 days. Four hours before each irradiation, 2.5 gm/m2 misonidazole was administered orally. Patients' ages ranged from 28-69 years. Karnofsky status for most patients was 80 or 90; the lowest grade was 60. The majority of patients had glioblastoma multiforms. Most were already on steroids prior to initiation of therapy. The median survival for the whole group was 12.0 months; 25% were alive at 18 months with some neurological compromise. The median survival remained unchanged for subgroups of patients with ages between 40-60 years and with Karnofsky performance status above 80. Among the 19 patients with glioblastoma multiforme, the median survival was 10 months. Acute toxicity was within tolerable limits. Details of toxicity and tissue analysis from post mortems and second craniotomy samples are presented.     

Interstitial brachytherapy for metastatic brain tumors

Since December 1979, 14 patients with progressive metastatic brain lesions have been treated with temporary implantation of high-activity iodine 125 sources using stereotaxic techniques. Four patients had prior surgical resections, and 13 had been treated with external whole-brain radiotherapy. Nine patients had brachytherapy performed at recurrence 4 to 16 months after conventional radiation therapy; the other four had implants as an adjuvant "boost" to the tumor area from 2 to 4 weeks after external radiation. Six patients have since died: two with stable brain lesions at 4 and 22 weeks, respectively; three with progressive systemic and CNS tumors at 23, 24, and 29 weeks, respectively; and one with progressive CNS disease 116 weeks postimplant. The remaining eight patients are alive with a median follow-up of 63 weeks (range, 52-239+ weeks). Median survival for the entire group is 80 weeks. Brain tumor brachytherapy may be useful for palliation and possible long-term survival in selected patients with solitary metastatic disease.     

Radiotherapy of malignant glioma--prospective randomized clinical study of whole brain vs local irradiation

Prospective randomized clinical study was conducted to evaluate the factor of radiation field in radiotherapy for malignant glioma from 1981 to 1988 at Tokyo Women's Medical College. Radiation methods were randomized to two groups; (I) whole brain (40 Gy) and local irradiation (18 Gy), total dose 58 Gy/29 f/6 weeks (TDF 91), (II) local irradiation, total 56 Gy/28 f/6 weeks (TDF 90). Twenty three cases were registered as group I and 26 cases as group II. Two and four years cumulative survival rate were 43% and 17% in group I and 39% and 27% in group II. There were no significant differences on response, survival, recurrent pattern, late effect and complications between whole brain and local irradiation. This study confirmed that local control was the most important in the treatment of malignant glioma.
