Abstract
Eighty patients with intramedullary spinal cord tumors were treated by microsurgical methods between 1988 and 1996. Twenty-nine patients were diagnosed with astrocytoma, 36 with ependymoma, five with metastasis, four with lipoma, three with dermoid or epidermoid tumor, two with neurofibroma, and one with neuroma. Vascular and infectious lesions (such as abscesses and hemangioblastomas) were excluded. After laminectomy, total removal of the lesion was achieved in 68 of 80 patients and subtotal removal in 12. Postoperative radiation therapy was performed in 13 of 80 patients. The follow-up period ranged from 12 to 92 months (mean 42.2 months). All patients underwent preoperative and postoperative magnetic resonance imaging at intervals ranging from 3 months to 5 years postoperatively. Four patients showed clinical and radiological evidence of local tumor recurrence during the follow-up period. Four patients died 5 months to 15 months postoperatively from the re-expansion of their primary metastatic disease. The operative results at long term (after the 6th postoperative month) were better than the results at short term (before the 6th postoperative month) and revealed clinical improvement in 63, no change in 10, and deterioration in seven patients. We recommend early radical surgery, whenever possible, to be performed when the patient's neurological status is still good. Subtotal removal and irradiation are better for malignant or metastatic tumors. Partial decompressive removal is best for large intramedullary lipomas. Plastic laminotomy with preservation of the intervertebral joints is especially recommended in young or middle-aged patients.

Abstract
Patients with suspected malignant spinal cord compression may present with a misleading sensory level or have multiple levels of compression that are not apparent clinically or on imaging of a limited area of the spine. To estimate how often this occurs and to evaluate a policy of magnetic resonance imaging (MRI) of the whole spine for any patient with suspected cord compression, data from 127 patients who had undergone MRI scans of the whole spine were reviewed. In 85 of 127 scans, there was evidence of compression of or impingement upon the spinal cord. A sensory level was present in 47 of these 85 patients, but in 12/47 (26%) the sensory level was four or more segments below or three or more segments above the actual lesion. Multiple levels of compression or impingement were found in 33 of 85 (39%) patients; in 24 of these, more than one region (cervical/thoracic/lumbar) of the cord was involved. For 32 patients who commenced radiotherapy to a treatment volume based on clinical criteria before the MRI scan was available, the radiotherapy fields needed modification in 16 (50%) as a result of the MRI findings. The results support a policy of MRI of the whole spine in any patient with suspected malignant spinal cord compression.

Abstract
We present a case of an exophytic spinal primitive neuroectodermal tumor that, radiologically, simulated an extramedullary nerve sheath tumor, meningioma, or metastatic tumor deposit. MR imaging provided discrete anatomic localization of the tumor, enabling exclusion of multicentricity in the brain and spinal cord.

Abstract
PURPOSE To review the University of Florida experience in treating ependymomas, analyze prognostic factors, and provide treatment recommendations. METHODS AND MATERIALS Forty-one patients with ependymoma and no metastases outside the central nervous system received postoperative radiotherapy with curative intent between 1966 and 1989. Ten patients had supratentorial lesions, 22 had infratentorial lesions, and 9 had spinal cord lesions. All patients had surgery (stereotactic biopsy, subtotal resection, or gross total resection). Most patients with high-grade lesions received radiotherapy to the craniospinal axis. Low-grade intracranial lesions received more limited treatment. Spinal cord lesions were treated using either partial spine or whole spine fields. RESULTS Of 32 intracranial tumors, 21 recurred, all at the primary site; no spinal cord tumors recurred. Overall 10-year survival rates were 51% (absolute) and 46% (relapse-free); by tumor site: spinal cord, 100%; infratentorial, 45%; supratentorial, 20% (p = 0.002). On multivariate analysis, tumor site was the only factor that influenced absolute survival (p = 0.0004); other factors evaluated included grade, gender, age, duration of symptoms, resection extent, primary tumor dose, treatment field extent, surgery-to-radiotherapy interval, and days under radiotherapy treatment. CONCLUSIONS Patients with supratentorial or infratentorial tumors receive irradiation, regardless of grade. Craniospinal-axis fields are used when spinal seeding is radiographically or pathologically evident. Spinal cord tumors are treated using localized fields to the primary site if not completely resected. Failure to control disease at the primary site remains the main impediment to cure.

Abstract
Primary intramedullary anaplastic oligodendroglioma is a rare tumor, only four cases of which have been reported. The authors present the case of a 38-month-old boy with primary intramedullary anaplastic oligodendroglioma. He underwent partial removal of the tumor and spinal radiation therapy. The residual tumor disappeared 12 months after radiation, and 48 months after treatment there was no evidence of recurrence. This case shows that in primary intramedullary anaplastic oligodendroglioma, postoperative radiation therapy confined to the spinal cord can yield an optimal result.

Abstract
OBJECT The purpose of this study was to devise an improved method of treating high-grade gliomas of the spinal cord in children who have a dismal prognosis following conventional treatment. METHODS Eighteen children with newly diagnosed high-grade astrocytomas arising in the spinal cord were enrolled in the Children's Cancer Group (CCG) protocol 945. Following surgery, they were all assigned to receive two cycles of "8-drugs-in-1-day" (8-in-1) chemotherapy prior to radiotherapy and eight additional cycles thereafter. A centralized neuropathology review was used to confirm the diagnosis of high-grade astrocytoma in 13 of the 18 children: anaplastic astrocytoma (eight patients), glioblastoma multiforme (four patients), and mixed malignant glioma (one patient). Diagnoses were discordant in five patients. There were eight boys and five girls in the group with confirmed diagnoses, with a median age of 7 years (range 1-15 years). The extent of resection was confirmed by computerized tomography or magnetic resonance (MR) evaluation in five of 13 patients. There were six gross-total or near-total resections (> 90%), four partial or subtotal resections (10-90%), and three biopsies. Six patients showed evidence of leptomeningeal metastases at diagnosis based on staging MR examinations. Eight of the 13 patients completed at least eight of the prescribed 10 cycles of chemotherapy; five received craniospinal radiotherapy and five spinal radiotherapy. CONCLUSIONS The 5-year progression-free and total survival rates for the 13 children were 46 +/- 14% and 54 +/- 14%, respectively. Seven patients suffered a relapse at the primary site, four of whom also had leptomeningeal metastases. Seven of the 13 patients (54%) remain alive at the time of this report at a median of 76 months (range 51-93 months) from study entry. Six patients died between 8 and 38 months after diagnosis, all with active disease. Intensification of therapy may further improve outcome in this high-risk population.

Abstract
BACKGROUND Patients with xeroderma pigmentosum (XP) frequently develop sunlight-induced skin cancer. Infrequently, internal neoplasms may also occur. A 21-year-old patient with XP, who had many skin cancers, developed a rare internal tumour - a grade II diffuse fibrillary spinal cord astrocytoma - during a break in a therapeutic trial of isotretinoin for skin cancer prevention. Treatment of neoplasms in XP patients presents special difficulties because of their defect in DNA repair. OBJECTIVE The study objective was to raise awareness of the cancer surveillance process in XP patients and the concerns involved in choice of therapy. METHODS Since the spinal cord tumour was inoperable, the patient was treated with x-radiation, continued on isotretinoin treatment and was followed closely for tumour response. RESULTS Despite sensitivity to sunlight, the patient had a normal acute response to the x-ray treatment without excessive skin reaction. Serial examinations by magnetic resonance imaging (MRI) starting 8 months after x-ray treatment was initiated, showed a marked gadolinium enhancement followed by regression. This clearing was first seen at 2 years after biopsy and persisted to at least 9 years after treatment. CONCLUSION In contrast to the exaggerated sensitivity to UV radiation, XP patients may tolerate therapeutic doses of x-radiation. Isotretinoin treatment may have contributed to the good response of this spinal cord astrocytoma.

Abstract
Spinal intramedullary metastases present with rapidly progressing neurological deficits and have an extremely poor prognosis. Prompt investigation and management are required. This case history illustrates that radiotherapy and steroids can be effective in returning motor function. The behaviour of the primary tumour and the stage of the disease influence whether surgery is appropriate.

Abstract
PURPOSE Postoperative radiation therapy adds significantly to disease control and survival of patients with ependymoma. However, much controversy exists about the radiation treatment policy. We report the long-term results of a cohort of 56 patients with primary intracranial and spinal ependymomas. Special effort has been taken to define prognostic indicators as a basis for future treatment strategies. PATIENTS AND METHODS Between November 1963 and May 1995, 56 patients with histological proven ependymoma were referred to our clinic for further treatment following surgery. Thirty patients had a high grading tumor and 26 had low grade tumors. Seventeen patients had supratentorial tumors and 24 had infratentorial tumors. Fifteen patients suffered from localized spinal tumors. RESULTS The mean survival time for all patients was 77 months. Five- and 10-year survival probabilities were 60 and 51%, respectively. The mean progression free survival (PFS) probability for all patients was 67 months with corresponding 5- and 10-year PFS probabilities of 53 and 39%, respectively. On univariate analysis initial performance status, age and tumor grade were significant for survival probability. Concerning PFS radiation dose was significant with improved survival with doses > 45 Gy. On multivariate analysis, tumor grade and initial performance status proved to be the only independent prognostic factors. CONCLUSIONS Tumor grade, age, initial performance status and radiation dose are significant factors for the clinical course of patients and have to be taken into account for the urgently needed prospective trials.

Abstract
Cavernous angiomas, also called cavernous malformations or cavernomas, are vascular hamartomas accounting for 3-16% of all angiomatous lesions of the spinal district. Although histologically identical, these vascular anomalies may exhibit different clinical behavior and radiological features, depending on their location, hinting at different managements and therapeutic approaches. The authors report 11 cases of symptomatic spinal cavernous angiomas diagnosed and surgically treated over the past 18 years. Age of patients ranged from 15-75 years; males outnumbered females. Three patients had vertebral cavernous malformations, secondarily invading the epidural space; two had pure epidural lesions; two patients had intradural extramedullary lesions, and four intramedullary lesions. Surgical removal was completely achieved in four patients with intramedullary lesions, in two with subdural extramedullary lesions, and in one with a pure epidural lesion. Subtotal excision of another one epidural and three vertebral cavernous angiomas was followed by radiotherapy. There was no morbidity related to surgery; the mean follow-up was 2 years. The outcome was excellent in two cases, good in six, and unchanged in the other three. The authors discuss the different modalities of treatment of these vascular lesions variously placed along the spine.

Abstract
Spinal cord astrocytomas are rare neoplasms, and optimal treatment guidelines are undefined, 23 patients with spinal cord astrocytomas were treated between 1984 and 1993 with conservative surgery and postoperative radiotherapy. The mean age was 31 years. Twelve patients were male and eleven female. All patients presented with neurologic deficit. Cervical cord was involved in five patients, cervicothoracic in four, thoracic in eight and thoracolumbar in six. Five patients had intramedullary cysts. Fifteen patients had low grade tumors and six high grade. Surgery was near total excision in three patients, partial excision in ten and biopsy in ten patients. All patients received postoperative radiotherapy to a median dose of 45 Gy in 25 fractions over 5 weeks. The median followup was 51 months (range 7-143 months). At 6 months post radiotherapy, twelve patients had improvement of neurologic status, nine had stable status, and two deteriorated. The actuarial overall survival was 55% at 5 years and 39% at 10 years. The actuarial progression free survival probability was 75% at 5 years and 55% at 10 years. Five patients had local failure and two failed at distant sites. Twelve patients died, six due to progressive disease, five due to complications of paraplegia and one patient of unrelated causes. Tumor grade was a significant prognostic factor for overall survival. 5 year overall survival was 79% for low grade tumors. No patient with high grade tumor survived more than 2 years and the median survival was 10 months. Low grade, female sex and presence of intramedullary cysts were associated with significantly improved progression free survival. Conservative surgery followed by radiotherapy appears to have a role in achieving tumor control and neurologic recovery in patients with low grade astrocytomas of the spinal cord. Treatment results of high grade tumors remain poor and new therapeutic strategies need to be studied.

Abstract
Intraspinal high-grade astrocytoma in children is an extremely rare tumor entity with disappointingly short survival times despite multimodality treatment. We report on a girl with anaplastic astrocytoma at level T9-11, who was treated with tumor resection, multidrug chemotherapy and irradiation. Local recurrence was diagnosed after 16 months. With reference to other cases reported in the literature, the course of disease, achievements and limitations of currently available therapeutic options, and potential future strategies are discussed.

Abstract
We report a retrospective study regarding 6 children with primary epidural non-Hodgkin's lymphomas and analyse the factors influencing prognosis with emphasis on treatment. Four patients were females and 2 males. The neurological condition of patients was assessed pre- and postoperatively according to Shaw's classification for neurological disability. All patients were submitted to surgery, radiotherapy and chemotherapy. Histologically, the tumour proved to be a high-grade non-Hodgkin's lymphoma in all cases. At follow-up, all patients are alive after a median interval of 52 months (range 24-72 months). This study showed that the outcome of patients depends on the gravity of pre-operative deficits whereas the survival is influenced by the type of treatment.

Abstract
Plain radiography, myelography and post-myelographic CT-scan are described and related to clinical findings in a prospective study of 153 consecutive patients with myelographic signs of spinal cord compression. The majority of the metastatic tumours arise in the vertebral body or the pedicles. In 80% of the patients with total blockage to the contrast medium on myelography the post-myelographic-CT showed passage of the contrast medium. Ambulatory function at time of diagnosis was correlated to the degree and the localization of the epidural block. In 64 patients who underwent a second myelography, the post-treatment findings of sensory function were correlated to radiological regression.

Abstract
Spinal ependymomas are rare intramedullary tumours, usually with a benign biological nature. They have, however, a known potential for recurrence and metastatic spread through the CSF pathways. Traditionally, radiotherapy has been employed as an adjuvant to surgery. Recently, however, this view has been increasingly questioned. Thirty-eight adult patients operated in the West Midlands between 1956 and 1994 were reviewed. Mean age at presentation was 37.8 years. Of all tumours 45% (17) were situated in the conus/cauda equina region, 26% (10) in the thoracic and 29% (11) in the cervical region. All patients underwent surgery as primary treatment. Postoperative mortality was 2.6% (one patient). Complete macroscopic excision of their tumours was performed in 14 patients; of these three received postoperative radiotherapy. Subtotal excision was performed in 18 patients, seven receiving adjuvant radiotherapy. Decompressive laminectomy and biopsy was performed in five patients with either no radiotherapy in one, radiotherapy in three or radiotherapy and chemotherapy in one. The overall survival rate was 87% at 5 years and 73% at 10 years for the whole series. In patients treated after the 1970s, the cumulative 10-year survival was 95%. Patients over the age of 40 years at diagnosis had a 10-year survival of 61% compared to 78% of those under the age of 40. Intramedullary tumours had a worse outcome with 68% survival at 10 years, compared to 89% of tumours at the cauda equina. Total excision carried 86% survival, subtotal excision 80% and biopsy only 25% at 10 years. In those patients treated by administration of postoperative radiotherapy the 10-year survival was 48%, compared to 96% in those in whom radiotherapy was not given postoperatively. Analysis of the recurrence and survival rates demonstrated that radiotherapy did not confer any significant protection against recurrence or disease progression. Whilst complete excision offers the maximal potential for cure, an expectant policy with possible repeat surgery may be appropriate when total excision is not achieved. The main conclusion to be drawn is that a randomized controlled trial of the value of adjuvant radiotherapy is greatly needed.

Abstract
A 15-year-old boy had metastasis to the spinal cord and then to the lung after an operation to remove a primary medulloblastoma. A medulloblastoma developed at the age of 10 years. The tumor was completely resected and the brain and spinal cord were irradiated. At the age of 13 years, metastasis to the sacral spinal cord developed and was treated with radiotherapy and intramedullary injection of methotrexate. At the age of 15 years, metastasis to the lung developed and was treated with chemotherapy (CBDCA, VP-16) followed by radiotherapy. Three months after the end of that therapy, the disease recurred but another course of radiotherapy and chemotherapy (VCR) was successful. Chemotherapy and radiotherapy were effective against metastatic lesions of medulloblastoma. With improvement in the survival rate among patients with medulloblastoma, we can expect incidence of extraneural metastases to increase. In addition to recurrence of the primary lesion and intramedullary dissemination, these metastatic lesions also require attention.

Abstract
INTRODUCTION Intraspinal meningiomas account for 25%-46% of primary spinal cord tumors. Technical advances in magnetic resonance imaging (MRI) and surgical procedures (ultrasonic cavitation aspirators [CUSA], lasers) have brought about better clinical results. In spite of these new techniques, a small percentage of patients still present with poor postoperative results and/or a recurrence. The authors tried to determine which data could influence clinical outcome and what therapeutic modalities could limit recurrence rate. MATERIALS AND METHODS We reviewed 54 patients who from 1963 to 1994, each had surgery for an intraspinal meningioma. There were 43 females and 11 males, aged 8 to 85 years old. Thirty-six (66.6%) patients were ambulatory on admission; only 2 presented with a paraplegia. Tumor location was cervical in 10 cases, thoracic in 43 cases, lumbar in 1 case. Forty-seven tumors were intradural, 5 epidural, 2 epidural and intradural. Thirty patients underwent a myelography, 10 a computed tomography (CT) scan, and 14 an MRI. Twenty-three spinal angiographies were performed before surgery. Complete removal was achieved in 50 patients (92.6%). Ultrasonic cavitation was used 10 times for debulking the tumor, and laser was used in 12 surgical procedures to perform hemostasis of the meningioma and to coagulate the dural attachment. RESULTS The majority of the neoplasms were meningothelial (N = 24) or psammomatous (N = 11). No mortality was noted. Morbidity concerned five patients: two pulmonary embolisms, one definitive paraplegia, one transient deficit, and one epidural suppuration, which necessitated a second operation. Mean follow-up was 28 months. Final functional results were very good in 85% and good in 13%; one patient (2%) worsened. Two recurrences were noted: one with clinical signs and the other with only CT-scan modifications. Both patients underwent complementary radiotherapy. DISCUSSION AND CONCLUSION The authors discuss factors influencing functional results. Sex, pregnancy, pathologic diagnosis, and recurrence do not seem to have any influence. Calcification of the meningioma, as well as an anterior dural attachment, are pejorative factors. They insist on preoperative angiography and point out the advantage of using a CUSA and/or a laser to debulk and coagulate the tumor itself and its dural attachment. They propose radiation therapy as an adjuvant treatment or an alternative to reoperation, which could be hazardous for some patients when, for instance, a recurrence is located in a critical area or when the patient's general status is fragile.

Abstract
The skeletal system is a frequent site of metastatic involvement from breast cancer, whose pattern of spread is such that cure becomes practically impossible. The best palliation with the minimum discomfort for the patient must therefore be the major objective. With an increasing number of reports about major surgical procedures for spinal metastases, we reviewed our series of patients submitted to radiotherapy. Of 2,189 breast cancer patients, we selected 28 who might have been potential candidates for surgical resection (with lesions only in the spine, only one or no more than three contiguous bodies involved and no other metastases). All these patients had been treated with 20 or 30 Gy plus systemic (chemo, hormone, or both) therapy. Follow-up revealed that all of them had developed new metastases outside the treated field within one year. Local control was achieved in 68% of patients and 75% of them had stable or better performance status at 3 months. Median survival was 36 months. From our analysis, even patients with a so called "solitary lesion" seem not to have a better prognosis than others. We conclude that radiotherapy is still the method of choice to treat vertebral metastases from breast cancer. The role of surgery should be limited to patients with neurologic compression or severe mechanical instability.

Abstract
PURPOSE This study attempted to determine if central nervous system (CNS) disease at diagnosis is a poor prognostic factor in children with acute lymphoblastic leukemia (ALL) and whether 6 Gy of spinal irradiation is an adequate dose for these patients. METHODS AND MATERIALS Previously the Children's Cancer Group (CCG) treated patients with ALL and CNS disease at diagnosis with cranio (24 Gy)-spinal (12 Gy) irradiation, as well as systemic and intrathecal chemotherapy. In a series of CCG trials completed in 1989 the spinal dose was empirically reduced to 6 Gy for patients receiving systemic chemotherapy with an intensive consolidation phase to limit hematopoietic toxicity. The spinal dose was left at 12 Gy for patients treated with a less intensive consolidation phase. RESULTS With a median follow-up for surviving patients of 74 months, the 5-year event-free survival for 53 patients with CNS disease at diagnosis was 69 +/- 13% (+/- 2 standard deviations), similar to the value obtained for 3364 patients without CNS disease, 67 +/- 2%. Corresponding values for 5-year survival were 77 +/- 12% and 80 +/- 1%, and for freedom from isolated first CNS relapse, were 90 +/- 9% and 94 +/- 1%. Event-free survival, survival, and freedom from isolated first CNS relapse in the 6-Gy group were as good as in the 12-Gy group. CONCLUSION CNS disease at diagnosis is not a poor prognostic factor for children with ALL who are treated with intensive systemic chemotherapy, craniospinal irradiation, and intrathecal chemotherapy. Six Gy is an adequate dose of spinal irradiation for these patients.

Abstract
Epidural spinal cord disease (ESCD), an infrequent complication of systemic non-Hodgkins lymphoma (NHL), can occur at diagnosis or at relapse, and is usually treated with radiotherapy, or infrequently surgical decompression. We retrospectively analyzed 140 patients with intermediate-grade NHL (IG-NHL) who were treated on a dose-intense protocol using doxorubicin, vincristine, and high-dose cyclophosphamide (NHL-15). There were seven episodes of ESCD in six (4.3%) patients. Five episodes were asymptomatic at presentation; one patient had back pain, leg numbness, and tingling; and one had radicular pain and mild leg weakness. None had malignant cells in the CSF. One patient received high-dose dexamethasone after laminectomy for diagnostic biopsy; otherwise, dexamethasone was used only as an anti-emetic prior to chemotherapy. Patients who developed ESCD at diagnosis received the planned course of NHL-15 chemotherapy as treatment for ESCD, and those treated with NHL-15 who developed ESCD at relapse were given a regimen containing ifosfamide, carboplatin, and etoposide (ICE). After chemotherapy alone, five of seven episodes showed radiographic resolution of ESCD and improvement of neurologic deficits. One patient received consolidation radiotherapy (2,700 cGy) to the spine after ICE for relapsed ESCD and had a complete response. One patient had progression of systemic lymphoma and ESCD despite chemotherapy. These data suggest that chemotherapy may be effective as initial treatment of ESCD in IG-NHL and may reduce the potential complications of spinal surgery and radiotherapy.

Abstract
AIMS AND BACKGROUND Gliomas of the conus medullaris often show characteristic clinical, radiological, and intraoperative features which differ from gliomas involving other parts of the spinal cord. METHODS Eight patients with histologically verified gliomas of the conus medullaris were diagnosed and studied. RESULTS There were five men and three women ranging in age from 21 to 59 years. Predominant initial symptoms were back pain (4 cases) and leg weakness (4 cases). The most common findings on admission were flaccid paraparesis with impaired sensation and bladder dysfunction. Postoperative magnetic resonance (MR) images with more than 95% removal of a tumour were defined as "subtotal removal" (noted in 4 of 8 cases), and less than 95% as "partial removal" (4 of 8 cases). All patients had postoperative radiotherapy. During the follow-up period ranging from 3 to 10 years, there was no tumour recurrence or regrowth on MR images. CONCLUSIONS The postoperative radiotherapy in gliomas of the conus medullaris where total resection is not possible seems provide a beneficial effect on preventing tumour regrowth.
