Abstract
BACKGROUND Patients with metastatic disease to the bone present a management challenge. Of the complications encountered in these patients, the predominant types that require surgical intervention are pathologic or impending fractures and neurologic compromise secondary to cord compression from spinal metastases. A multimodality approach is helpful in caring for these patients, and addressing complications related to bony metastatic disease with timely and appropriate intervention is an important step in optimizing care and quality of life. METHODS This article incorporates information from multiple sources and presents recent reviews of the experience at the Memorial Sloan-Kettering Cancer Center with acetabular reconstruction for metastatic lesions, and with the use of the posterolateral transpedicular approach to address metastatic disease in the spine. RESULTS Of 55 patients who underwent reconstruction of the acetabulum for metastatic disease, although there was a 25% incidence of local disease progression, there was only a 9% incidence of late fixation failure. Of the 41 who were evaluable at 3 months, 83% continued to experience significant pain relief, and 50% of nonambulatory patients regained walking ability secondary to the procedure. Of the patients with more than 2 years of follow-up, 86% maintained pain relief and 71% maintained their ability to ambulate and function in their community. The preliminary series of 25 patients managed with a posterolateral transpedicular approach to address metastatic disease in the spine showed excellent tumor control, pain relief, and neurologic preservation with the technique. Particular benefit was obtained for patients with extensive epidural disease in which an anterior approach was contraindicated. CONCLUSIONS Although a multimodality approach to the treatment of patients with metastatic disease to bone combining appropriate surgical intervention with systemic therapy and radiation can entail a major operative procedure, the overall benefits to a patient's quality of life outweigh the risks in most cases. Clinician awareness of the various therapeutic options and their indications, and aggressive advocacy of quality of life for these patients, can improve the care delivered to people with metastatic disease.

Abstract
Spinal cord compression by epidural metastasis is considered an exceptional complication in patients with cervical carcinoma. We report three patients treated for a cervical carcinoma who developed epidural metastasis with spinal cord compression at 9, 25 and 48 months after primary treatment of the uterine malignancy. All patients had poorly-differentiated adenocarcinomas with lymphovascular space invasion, and two had lymph node metastasis. All patients underwent emergency decompressive laminectomy followed by radiotherapy and a partial recovery of the neurological function was achieved. In two patients the spinal cord was the only site of recurrent disease, whereas the other had lung and brain metastasis at the time of epidural involvement diagnosis. All three patients, however, died of disseminated disease. Surgical decompression followed by radiation therapy may result in a complete preservation of the neurologic functions in patients with spinal cord compression secondary to metastatic carcinoma of the uterine cervix. Considering the propensity for disseminated disease, long term survival might be achieved only with the use of effective chemotherapy.

Abstract
BACKGROUND Radiotherapy is used commonly to provide pain relief for painful bone metastases, and there is a perception that of the three-quarters of patients who achieve pain relief, half of these stay free from pain. However, the precise contribution from radiotherapy may be unclear because of difficulties in assessing the numbers of people achieving relief, the extent of relief and its duration, and the influence of other contemporaneous interventions, such as analgesics. OBJECTIVES To assess pain relief from: 1. localised bone metastases achieved by radiotherapy, comparing the efficacy of different fractionation schedules 2. more generalised metastatic disease achieved by radiotherapy or radioisotopes. SEARCH STRATEGY Studies were identified by searching Medline (1966 to August 1998), Embase (1980 to 1998), the Cochrane Library (1998 Issue 3) and the Oxford Pain Relief Database (1950 to 1994). SELECTION CRITERIA The inclusion criteria used were: full journal publication, patients with pain due to bone metastases, and random allocation to a radiotherapeutic intervention (either external irradiation or administration of radioisotopes). DATA COLLECTION AND ANALYSIS The number of patients achieving complete pain relief and at least 50% at one month were compared with an assumed natural history of 1 in 100 patients achieving pain relief without treatment to obtain the number-needed-to-treat (NNT). Summed pain relief or pain intensity difference over four to six hours was extracted, converted into dichotomous information yielding the number of patients with at least 50% pain relief, and used to calculate the relative benefit and the NNT for one patient to achieve at least 50% pain relief. MAIN RESULTS Twenty trials reported on 43 different radiotherapy fractionation schedules and eight studies of radioisotopes. Radiotherapy produced complete pain relief at one month in 395/1580 (25%) patients, and at least 50% relief in 788/1933 (41%) patients at some time during the trials. There were no differences in the proportions of patients achieving these outcomes between single or multiple fraction schedules. The number-needed-to-treat (NNT) to achieve complete relief at one month (compared with an assumed natural history of 1 in 100 patients whose pain resolved without treatment) was 4.2 (95% CI 3.7-4.7). No pooled estimates of speed of onset of relief, or of its duration, could be obtained. In the largest trial (759 patients) 52% of those who had complete relief had achieved it within four weeks, and the median duration of complete relief was 12 weeks. For more generalised disease, radioisotopes produced similar analgesic results to external irradiation. Adverse effect reporting was poor. There were no obvious differences between the various fractionation schedules in the incidence of nausea and vomiting, diarrhoea or pathological fractures. REVIEWER'S CONCLUSIONS Radiotherapy is clearly effective at reducing pain from painful bone metastases. There was no evidence of any difference in efficacy between different fractionation schedules, nor indeed of a dose-response with total dose of radiation. For treatment of generalised bone pain both hemibody irradiation and radioisotopes can reduce the number of painful new sites.

Abstract
Currently, there is a lot of focus directed toward discovering treatments for patients with hormone refractory prostate cancer (HRPC) that will lead to increased survival. Until such treatments emerge, palliation is important to ensure patients the highest possible quality of life. Most disabling among symptoms associated with disease progression are bone pain, bone fracture, urinary tract obstruction, spinal cord compression, coagulation disorders, anemia, and edema. Diverse treatments, such as radiation therapy, surgery, chemotherapy, and supportive measures, can improve the impact of these problems, although improved symptom control is needed in some areas.

Abstract
The unfortunate reality of metastatic breast cancer is that all treatment is palliative in nature. This is a disease that currently has no cure and for which therapy is directed towards accentuating survival and relieving symptoms. Current technology allows the prediction and detection of metastases earlier and with greater accuracy. These achievements need to be consolidated by the discovery of innovative therapies that can alter the inevitable outcome of this disease.

Abstract
STUDY DESIGN The risk factors for complications and complication and survival rates in patients with metastatic disease of the spine were reviewed. A retrospective study was performed. OBJECTIVES To determine the surgical complication and survival rates of patients with metastatic disease of the spine and risk factors for complication occurrence. SUMMARY OF BACKGROUND DATA The role of surgical intervention for patients with metastatic disease of the spine has been controversial. Several risk factors for surgical complications have been identified. Short survival times and high complication rates have failed to justify surgical intervention in many cases. METHODS Patients (n = 80) undergoing surgical treatment for metastatic disease of the spine were reviewed. Surgical indications included progressive neurologic deficit, neurologic deficit failing to respond to, or progressing after, radiation treatment; intractable pain; radioresistant tumors; or the need for histologic diagnosis. Patients underwent anterior, posterior, or combined decompression and stabilization procedures. Neurologic examination was recorded before surgery, postoperative period, and at least follow-up. Complication and survival rates were calculated. Several variables were examined for risk of complication. RESULTS The mean age at time of surgery was 55.6 years (range, 20-84 years). Mean survival time after the diagnosis of spinal metastasis was 26.0 months (range, 1-107.25 months). Mean survival time after surgery was 15.9 months (range, 0.25-55.5 months). Sixty-five patients showed no change in Frankel grade, 19 improved one Frankel grade, and 1 deteriorated one Frankel grade; 1 patient had paraplegia. Thirty-five complications occurred in 20 patients (25.0%). Ten patients (12.5%) had multiple complications accounting for 23 of the 35 postoperative problems (65.7%). Sixty patients had no surgical complications (75%). There were no intraoperative deaths. CONCLUSIONS The likelihood that a complication occurred was significantly related to Harrington classifications demonstrating significant neurologic deficits and the use of preoperative radiation therapy. In general, Harrington classifications with neurologic deficits and lower Frankel grades before and after surgery were associated with an increased risk of complication. Overall, the major complication rate was relatively low, and minor complications were successfully treated with minimal morbidity. The relatively long survival time after spinal surgery in this group of patients justifies surgical treatment for metastatic disease. Most complications occurred in a small percentage of patients. To minimize complications, patients must be carefully selected based on expected length of survival, the use of radiation therapy, presence of neurologic deficit, and impending spinal instability or collapse caused by bone destruction.

Abstract
BACKGROUND A retrospective study was performed to examine the outcome of patients with colorectal cancer who had metastatic spinal cord compression (MSCC) and received radiation therapy (RT). METHODS Forty episodes of MSCC were treated with external beam RT in 34 patients with metastatic colorectal cancer. The median total dose was 3000 cGy (1800-4750 cGy), and the daily fraction size was 300 cGy (151-400 cGy). All patients were followed until death. RESULTS Median overall survival for the entire cohort was 4.1 months. Of 21 patients ambulatory before RT, 20 remained ambulatory after treatment, whereas only 2 of 9 patients who were nonambulatory regained full ambulatory status. Patients with rectal primary tumors had improved survival (median 7.9 months) compared with those who had colon primary tumors (2.7 months) (P = 0.002). Patients who received a total dose of more than 3000 cGy had a better survival (7 months) than those who received 3000 cGy or less (3.1 months) (P = 0.024). There was a trend for improved survival in patients fully ambulatory at diagnosis (P = 0.056) and after RT (P = 0.07). Unlike other primary sites in which approximately 70% of lesions are located in the thoracic spine, the location of epidural metastasis in colorectal primary tumors was most frequently in the lumbar spine (55% of lesions). CONCLUSIONS Prognostic features and outcomes for MSCC with primary colorectal cancer are similar to those for other primary sites. There is a suggestion that rectal primary tumors may be associated with an improved outcome compared with colon primary tumors. Patients who received more than 3000 cGy total dose had a longer survival than those who received lower total doses.

Abstract
General internists often care for patients with advanced cancer. These patients have substantial morbidity caused by moderate to severe pain and by spinal cord compression. With appropriate multidisciplinary care, pain can be controlled in 90% of patients who have advanced malignant conditions, and 90% of ambulatory patients with spinal cord compression can remain ambulatory. Guidelines have been developed for assessing and managing patients with these problems, but implementing the guidelines can be problematic for physicians who infrequently need to use them. This paper traces the last year of life of Mr. Simmons, a hypothetical patient who is dying of refractory prostate cancer. Mr. Simmons and his family interact with professionals from various disciplines during this year. Advance care planning is completed and activated. Practical suggestions are offered for assessment and treatment of all aspects of his pain, including its physical, psychological, social, and spiritual dimensions. The methods of pain relief used or discussed include nonpharmacologic techniques, nonopioid analgesics, opioids, adjuvant medications, radiation therapy, and radiopharmaceutical agents. Overcoming resistance to taking opioids; initiating, titrating, and changing opioid routes and agents; and preventing or relieving the side effects they induce are also covered. Data on assessment and treatment of spinal cord compression are reviewed. Physicians can use the techniques described to more readily implement existing guidelines and provide comfort and optimize quality of life for patients with advanced cancer.

Abstract
PURPOSE To evaluate the effectiveness of a multidisciplinary approach to spinal cord compression (SCC) in accordance with prospective protocol, providing a uniform approach to diagnosis, decision making concerning optimal treatment modality in any particular case of SCC, treatment performance and evaluation of treatment results. The SCC patients treated by radiation therapy are described. MATERIALS AND METHODS Patients with SCC were examined and treated by a multidisciplinary team consisting of a neurologist, radiologist, oncologist, orthopedic surgeon, and neurosurgeon. Seventy-nine patients for whom radiation was recommended received a 30 Gy radiation dose to a compression-causing mass and course of high dose dexamethasone. Three fractions of 5 Gy and 5 fractions 3 Gy each were delivered by Co60 or 8 MV photon beam in 12 days. Treatment outcome was essentially evaluated by ambulation capabilities which were considered to be the main problem of SCC. Changes in other neurologic motor, sensory and autonomic disturbances were also evaluated. RESULTS Seventy-two percent of the patients were already non-ambulatory at diagnosis. The first symptom was motor deficiency in only 33% of them while in all other cases it was pain. Ambulation capability was the main prognosticator of treatment outcome; 90% of patients who were ambulatory before treatment remained so while 33% of the non-ambulatory patients regained their ability to walk. The grade of motor disturbance was also an important variable: among the non-ambulatory patients, 50% of the paretic but only 14% of the plegic ones became ambulatory. Overall, 51% of the study patients were ambulatory after undergoing radiation. The ambulatory state after treatment was the main predictor for survival. CONCLUSION Close cooperation of a multidisciplinary team in diagnosis and treatment according to the above protocol enabled the achievement of good results of radiation treatment in SCC. Early diagnosis and early treatment should further enhance therapeutic outcome.

Abstract
OBJECT Laminectomy for the treatment of spinal metastatic disease is ineffective. Total spondylectomy requiring both anterior and posterior operations may cause undue morbidity in patients with a limited life expectancy. The authors demonstrate the technique, feasibility, and success of subtotal vertebrectomy that is followed by anterior and posterior reconstruction via a simple posterior approach. Although this remains a palliative procedure, it provides circumferential decompression and spinal stabilization by using rigid hardware. METHODS The authors present a review of nine of 43 consecutive patients with spinal metastatic disease who underwent operation in a 42-month period. Via a single midline posterior approach, the authors performed single-stage circumferential decompression of the theca followed by anterior and posterior reconstruction. Anterior support is provided by a methylmethacrylate reconstruction retained with Steinmann pins. Posterior reconstruction is achieved by placement of rigid hook or pedicle screw and rod instrumentation. Eight of the nine patients died of progression of underlying disease. All patients remained pain free until days before they died. Except for a patient with paraplegia who did not recover, all other patients remained ambulatory. Despite radio-, chemo-, and steroid therapy, there were no wound infections or breakdowns. One patient underwent reoperation because of a technical error. CONCLUSIONS Use of the near-total vertebrectomy followed by anterior and posterior reconstruction from T2 to L3 by using a single midline posterior approach spares the patient, who has a limited life expectancy, the operative risks associated with thoracotomy or thoracoabdominal approaches. The authors restrict the procedure for use in patients with extensive bony disease, noncontiguous spinal involvement, visceral metastases, other contraindications to a transcavitary procedure, and those with advanced age.

Abstract
PURPOSE In contrast with many analyses of surgical treatment for spinal metastases, there have been only a few recent well-documented publications assessing nonsurgical treatment. This paper is a study of the outcome of nonsurgical therapy for metastatic tumors of the spine. METHODS AND MATERIALS One hundred and one patients with spinal metastases were treated with radiation therapy and/or chemotherapy without surgical intervention between 1990 and 1995, in prospective analysis, and had follow-up for more than 24 months. This study included 59 men and 42 women with a mean age of 61 years (range: 14 to 81). Mean follow-up periods were 11 months for patients dying of the disease and 53 months for the survivors. Neurological status, pain relief, functional improvement, and cumulative survival rate were assessed. RESULTS Of the total treated, 67 patients (66%) were evaluated as being neurologically stable or improved after treatment. Pain relief was achieved in 67%, and 64% showed functional improvement. Primary lesion responsiveness to nonsurgical therapy influenced the survival, neurological recovery, pain control, and function. Neurological findings before therapy were useful in predicting ambulatory status after treatment. CONCLUSION Nonsurgical treatment was often successful when primary tumors had responsiveness to radiation therapy and/or chemotherapy. We found this to be evident even when neurological deficits were found, particularly in lumbar spines. Spinal metastases of tumors with less responsiveness, unless patients were neurologically intact, responded poorly to therapy. Most of the patients who were successfully treated enjoyed relief lasting nearly until death. Their functional ability was limited by general debility, rather than by local tumor regeneration.

Abstract
PURPOSE Retrospective analysis of analgesic, decompressive and remineralization effects of radiation therapy for spinal metastases in breast cancer. PATIENTS AND METHODS From January 1990 to December 1992, 108 patients with breast cancer were treated by irradiation at the Bergonié Institute for a first spinal metastasis. Three patients had undergone previous surgery (laminectomy and Doves' frame). The indication of radiation therapy was analgesic (102 patients) or decompressive (six patients). The usual irradiation scheme was 30 Gy/10 fractions/2 weeks. RESULTS The analgesic effect was considered as 'complete' or 'almost complete' (83%), 'moderate' (13%) or absent (4%). The mean time to the maximum analgesic response was 35 days. The duration of both the analgesic response and remineralization effects could not be retrospectively assessed due to lack of data. Decompressive effects were complete in five cases and absent in one case. A second spinal radiation therapy was necessary 78 times (eight times in junction field within 6 months following the first treatment). Spinal cord compression occurred either out of (three cases) or within (one case) the irradiated field. CONCLUSION Radiation therapy for spinal metastases in breast cancer remains a palliative analgesic treatment. Indication for decompression is rare. However, assessment of compressive 'risk' leads to discussion of radiological staging (contribution of magnetic resonance imaging) and possible previous treatment (vertebroplasty or osteosynthesis).

Abstract
BACKGROUND AND PURPOSE Spinal cord compression (SCC) is an important complication of metastatic prostate cancer. We have analysed patients treated at the Royal Marsden Hospital to assess treatment outcome and prognostic factors in this patients group. MATERIALS AND METHODS We performed retrospective analysis of 69 patients with spinal cord compression and prostate cancer treated at the Royal Marsden Hospital. RESULTS At presentation 40 (58%) patients were non-ambulant and 52% were catheterised. Diagnosis was established by myelography in 42% and magnetic resonance imaging (MRI) in 47% of patients. MRI detected significantly more patients with multiple sites of compression (51 versus 7%, P < 0.001). SCC was present at the initial diagnosis of prostatic cancer in 13 patients and 17 patients had received no hormone treatment prior to diagnosis. Following treatment 36 (52%) patients had a functional improvement of motor power with 25/40 (63%) non-ambulant patients becoming ambulant. Seventy-seven percent of patients who had eventual improvement had some improvement in power within 7 days. On multivariate analysis a single level of compression, no previous hormone therapy and a young age (<65 years) predicted for better outcome. When these factors were included an increased radiation dose (>30 Gy) or the addition of surgery did not improve the functional outcome. Following initial recovery; there was a 45% risk of developing a further episode of cord compression at the same or new site by 2 years with a median time to progression of 236 days (range 47-1215 days). The median survival was 115 days (range 5-2016 days) with 25% of patients surviving for 2 years. Patients with no prior hormone therapy had a median survival of 627 days (range 46-1516 days). Other predictors of improved survival on multivariate analysis were a single site of compression and a haemoglobin over 12 g. CONCLUSIONS Treatment of SCC in prostate cancer results in improved motor function in the majority of patients. Long-term survival is possible, especially in good performance status patients with no prior hormone treatment. Survivors remain at high risk of subsequent neurological relapse. An early improvement in motor power is a strong predictor of subsequent functional improvement. MRI detects additional sites of asymptomatic SCC which makes it the investigation of choice.

Abstract
In this third article in the series, the management of patients with symptoms arising as a consequence of metastatic disease involving peripheral nerves, the spinal cord and the brain are discussed. In particular, pain, spinal cord compression and symptoms due to either raised intracranial pressure or specific neurological deficits may substantially impair the quality of life in patients with advanced cancer. Pain control, using both medical and surgical treatments, are discussed. The principles underlying the diagnosis and treatment of metastases to the vertebral column and spinal cord, as well as intracranial deposits, are outlined.

Abstract
PURPOSE To evaluate the clinical outcome and toxicity of a short-course regimen of radiotherapy (RT) in selected metastatic spinal cord compression (MSCC) patients. METHODS AND MATERIALS Between 1993 and 1995, 53 consecutive patients with MSCC from low radio-responsive primary tumors (non small cell lung, kidney, head and neck and gastrointestinal carcinomas, melanoma and sarcomas), or more radio-responsive ones (breast and prostate carcinomas, myeloma and lymphomas) with paresis, plegia, low performance status (PS ECOG > or = 2), and/or short life expectation, underwent short-course RT; a single fraction of 8 Gy repeated after 1 week in responders or stable patients, for a total dose of 16 Gy. Of 49 (92%) evaluable cases, 4 (8%) underwent surgery plus RT and the other 45 RT alone. Medium doses of parenteral dexamethasone (8 mg x 2/d) were given in all cases and precautional anti-emetics to those treated with fields covering the upper abdomen (20 of 49 cases). Median follow up was 25 months (range, 6-34). Response was assessed according to back pain, and motor and bladder capacity before and after RT. RESULTS Pain relief was achieved in 67% of patients and motor function response rate reached 63%. Early diagnosis and therapy were very important in predicting response to RT; all but two (91%) pretreatment walking patients and all but one (98%) with good bladder function preserved these capacities. On the contrary, when diagnosis was late, only 38% of nonambulatory patients and 44% of those with bladder retention improved. Median survival was 5 months, with a 30% probability of survival for 1 year. Length of survival was significantly longer for patients able to walk before and/or after RT. Good agreement between survival and duration of response was found with no evidence of relapse in the irradiated spine. Sickness appeared only in a few cases. Slight esophagitis was more frequent: dysphagia for solid foods in one-third of patients irradiated on the thoracic spine. Late toxicity was never recorded. CONCLUSION The short-course RT adopted gave a clinical outcome comparable with that resulting from more protracted regimens with only slight side effects. The use of a few large treatment fractions could be explored considering the associated advantages for patients and radiotherapy centers often overloaded by long patient waiting lists.

Abstract
Approximately one half of prescribed radiotherapy is given for palliation of symptoms due to incurable cancer. Distressing symptoms including pain, bleeding, and obstruction can often be relieved with minimal toxic effects. Painful osseous metastasis is common in oncologic practice. Ninety percent of patients with symptomatic bone metastases obtain some pain relief with a lowdose, brief course of palliative radiotherapy. One half of the responding patients may experience complete pain relief. A single dose of 800 cGy in the setting of painful bone metastasis may provide pain control comparable to more protracted treatment at a higher dose of radiation. Patients with lytic disease in weight-bearing bones, particularly in the presence of cortical destruction, should be considered for prophylactic surgical stabilization of their condition. Routinely a brief, fractionated course of radiotherapy is given postoperatively. Pain due to multiple bone metastases uncontrolled by analgesics can be managed with single doses of halfbody irradiation. Doses of 600 cGy delivered to the upper half-body (above the umbilicus) and 800 cGy to the lower half-body (from the umbilicus to the middle of the femur) will provide some pain relief in 73% of patients. Half-body techniques have been investigated as prophylactic treatment, as a complement to local-field irradiation, and as fractionated rather than singledose therapy. Although intravenous administration of strontium 89 has been associated with myelosuppression, this treatment has been shown (a) to relieve pain due to bone metastasis and (b) to delay development of new painful sites. Recent data from phase III trials demonstrated that bisphosphonates have a role in reducing skeletal morbidity due to bone metastasis. Bone pain was reduced, and the incidence of pathologic fracture and the need for future radiotherapy was decreased. Radiotherapy relieves clinical symptoms in 70% to 90% of patients with brain metastases. Brief treatment schedules (e.g., 2000 cGy in five fractions over 1 week) are as effective as more prolonged therapy. Patients with solitary brain metastasis and no extracranial disease or controlled extracranial disease should be considered for surgical resection, because phase III data indicate enhanced survival with such an approach. Whole-brain radiotherapy is routinely administered postoperatively. A phase III study is examining the impact of accelerated fractionated doses of radiotherapy (two treatments per day) on survival of patients with brain metastases. Stereotaxic radiosurgical treatment is becoming increasingly available and permits delivery of radiation to metastatic intracranial tumor with minimal exposure of normal surrounding brain This treatment is most commonly used at the time of a solitary recurrence of disease in patients who previously received whole-brain radiotherapy. A role for this modality in newly diagnosed brain metastases remains to be defined. Chest symptoms are common in patients with locally advanced lung cancer and are effectively palliated with one 1000 cGy or two 850 cGy one fraction doses of radiation to the thoracic inlet and mediastinum. Chest pain and hemoptysis are more effectively palliated than cough and dyspnea. In patients with stage III cancer there is no compelling evidence that radiotherapy confers a survival advantage, and it may be reasonable to administer thoracic radiotherapy only when the patient has significant symptoms and the goal is to achieve control of these symptoms. Approximately 75% of the cases of superior vena cava syndrome are due to lung cancer, and small-cell lung cancer is the most common histologic type. A histologic diagnosis should be obtained before treatment is started, because detection of lymphoma or small-cell carcinoma would necessitate systemic therapy. Eighty percent of the patients with vena cava syndrome due to malignant disease achieve symptom relief with a brief, fractionated, palliative course of rad

Abstract
The aims of this study were to document the efficacy of treatment and to identify factors that were predictive of the outcome in malignant epidural spinal; cord compression. The medical records of patients treated at the Prince Henry and Prince of Wales Hospitals in the period 1980-1989 with a diagnosis of malignant epidural spinal cord compression were reviewed. A total of 94 patients were eligible for the study and were treated by radiotherapy alone (37), surgery alone (19) and surgery followed by radiotherapy (38). Efficacy was determined by measuring complete resolution of symptoms and signs at 1 month after presentation, and also by using an overall functional improvement score (FIS). Complete resolution of individual pre-treatment symptoms that were measured 1 month after treatment occurred as follows: pain (30/88), sensory disturbance (12/61), weakness (8/17), bladder dysfunction (10/42), and bowel dysfunction (10/36). Complete resolution of motor deficit occurred in 7/82 and of sensory deficit in 9/73. The ability to walk was regained in 19/51 previously non-ambulatory patients, and bladder function improved sufficiently to remove an indwelling catheter in 9/32 previously catheterized patients. As judged by FIS, 67 patients improved, 15 patients remained stable and 12 patients deteriorated. Of the treatments given, a combination of surgery followed by radiotherapy was associated with the greatest functional improvement (P = 0.001). The coexistence of 'liver failure' was the only patient-related factor identified which was associated with outcome (P = 0.041). The treatment of malignant spinal cord compression appears to be worthwhile; however, the outcome of treatment is not easy to predict from pretreatment factors. A 'functional improvement score' may be useful in assessing treatment efficacy.

Abstract
BACKGROUND AND PURPOSE Central nervous system (CNS) metastasis occurs in at least 30% of patients with breast cancer. Standard treatment is the same as in other solid tumors, though clinical behavior, and sensitivity to radiation therapy (RT) and to chemotherapy may differ considerably. Most of these patients die within a few months, but a substantial subgroup may survive a year or more. The last decade has given rise to new diagnostic methods, new surgical and radiotherapeutic techniques, and the clinical evidence of a chemotherapy permissive blood-brain barrier in CNS metastases. The literature was reviewed to assess the clinical impact of early diagnosis, recognition of prognostic factors, and of the recently developed therapeutic approaches. MATERIAL AND METHODS Review of the literature on CNS involvement in breast cancer focusing on clinical studies on early diagnosis, new modes of treatment, and factors influencing outcome. RESULTS Although randomized studies are still awaited, systemic chemotherapy seems a valuable alternative for RT of brain metastases in selected cases. In meningeal carcinomatosis, long survival may be independent of intraventricular chemotherapy. Neurotoxicity of intensive intraventricular treatment is considerable. In epidural metastasis, early diagnosis with prompt start of treatment remains the crucial factor for outcome. Radiation therapy is the mainstay of treatment of epidural metastasis, but new surgical techniques and even systemic chemotherapy should be considered in selected cases. CONCLUSIONS Recognition of prognostic factors combined with appropriate use of various recently developed therapeutic possibilities will improve the clinical outcome including better local tumor control and less treatment-induced neurotoxicity in a considerable number of patients with CNS metastasis from breast cancer.

Abstract
OBJECTIVE To describe the diagnosis, management, and outcome in 10 patients with histologically confirmed primary spinal epidural non-Hodgkin's lymphoma. MATERIAL AND METHODS We review the findings in a cohort of seven men and three women in whom this tumor was diagnosed between January 1979 and January 1993 and discuss the prognostic differences between primary and secondary spinal lymphomas. RESULTS All patients (median age at diagnosis, 70 years) underwent a decompressive laminectomy, subtotal tumor resection, and spinal irradiation (median dose, 3,800 cGy). Nine of 10 tumors were of B-cell origin. Six patients are alive and well. In four patients, recurrent disease developed from 15 to 62 months after the original diagnosis; of these, one has died. The median duration of survival of all patients was 42 months; of those living more than 24 months after diagnosis, the median duration of survival was 80 months. CONCLUSION A rapidly progressive spinal cord or cauda equina syndrome with neuroimaging findings consistent with an extradural compressive lesion should alert caregivers to the possibility of spinal epidural lymphoma. Although the prognosis for patients with secondary spinal epidural non-Hodgkin's lymphoma is often poor, primary spinal epidural non-Hodgkin's lymphoma can be associated with a favorable outcome if diagnosed and treated early.

Abstract
It is well accepted that the treatment of spinal tumors that threaten neurological integrity comprises resection, vertebral body reconstruction, and stabilization if the patient's condition is suitable. In spite of the excellent results reported using thoracotomy, the majority of investigators recommend posterolateral techniques because of lower morbidity, shorter hospitalization time, and the possibility of performing dorsal stabilization via the same incision. To overcome some of the disadvantages of thoracotomy, the authors developed an anterior procedure that permits vertebrectomy, reconstruction, and stabilization to be performed entirely by endoscopic technique. Microsurgical endoscopy and stabilization were performed in four patients with metastatic disease of the thoracic spine. All were ambulatory after surgery and at follow up; preoperative neurological and neurophysiological deficits improved as well. No complications occurred in this small series. Microsurgical endoscopy achieves a substantial reduction in trauma, use of analgesic medications, and hospitalization time. Early results seem to indicate that adequate decompression, stabilization and reduction of surgical morbidity can be achieved with this technique.

Abstract
This synthesis of the literature on radiotherapy for skeletal metastases is based on 171 scientific articles, including 13 randomized studies, 24 prospective studies, and 79 retrospective studies. These studies involve 13054 patients. Radiotherapy has been well documented as a method for alleviating pain, but the mechanisms underlying this effect are largely unknown. When used for pain palliation, radiotherapy achieves freedom from pain, or substantial alleviation of pain in nearly all cases, with few side effects. Half-body irradiation is effective in treating multiple metastatic sites and should be considered for use more frequently. However, this increases the requirements on equipment, dosimetry, and hospital beds. Systemic radiotherapy with radionuclides may be indicated for generalized skeletal pain. The role of radiotherapy in preventing or healing fractures is not fully evaluated. Optimum dose levels and fractionation schedules have not been established. Early radiotherapy for spinal cord compression may prevent symptoms from worsening, but the effects on existing paralysis are modest.

Abstract
BACKGROUND Factors affecting survival were determined for 109 patients with thoracic spine metastases and cord compression. Lung, prostate, and breast were the most common primary sites (78%). All patients had surgical decompression of the spinal cord, and 99% received radiotherapy. METHODS Survival was determined based on anatomic site of primary carcinoma, preoperative neurologic deficit, extent of disease, number of vertebral bodies involved, tumor location (site of cord compression), and age. The respective compounding weight of the negative prognostic factors also was analyzed in terms of survival. RESULTS The overall median survival was 10 months. Patients preoperatively ambulatory survived statistically significantly longer than nonambulatory patients or those with sphincter incontinence (P = 3.469 x 10(-6)). Patients with renal cell carcinoma survived the longest, followed by those with breast, prostate, lung, and colon cancer. Patients with breast cancer survived statistically longer than those with lung cancer (P = 0.039). Patients with one vertebral body involved survived statistically significantly longer than patients with multiple vertebral level involvement (P = 0.027). Extent of disease, age, and tumor location did not significantly influence survival. In patients with vertebral column disease, the presence of two or more poor prognostic indicators (leg strength 0/5-3/5, lung or colon cancer, multiple vertebral body involvement), had a compounding adverse effect on survival. CONCLUSIONS For patients with spinal metastases and cord compression, the factors found to affect survival include preoperative neurological status, anatomic site of primary carcinoma, and number of vertebral bodies involved. Patients with vertebral column disease and two or more of the poor prognostic indicators have a short life expectancy, and, therefore, radical surgery is not recommended because the benefits may not be substantial.

Abstract
Anterior spinal decompression has become widely used for neoplasia arising from the vertebral bodies. Replacement for the resected vertebral body must achieve spinal stability, restitution of lost height, correction of kyphotic deformities, and allow for early ambulation. A spinal fixator based on the Harrington ratchet locking system was found to fulfill this requirement. The fixator, its technique of implementation, and surgical results in 10 patients are described.

Abstract
PURPOSE In assessing effectiveness of radiation therapy (RT) in metastatic spinal cord compression (MSCC), we performed a prospective trial in which patients with this complication were generally treated with RT plus steroids, and surgery was reserved for selected cases. METHODS AND MATERIALS Two hundred seventy-five consecutive patients with MSCC entered this protocol. Twenty (7%) underwent surgery plus RT, another 255 received RT alone. Of all eligible patients, 25 (10%) early deaths and 21 (8%) entering a feasibility study of RT without steroids, were not evaluable. Of the 209 evaluable cases, 110 were females and 99 males, and median age was 62 years. Median follow-up was 49 months (range, 13 to 88) and treatment consisted of 30 Gy RT (using two different schedules) together with steroids (standard or high doses, depending on motor deficit severity). Response was assessed according to back pain and motor and bladder function before and after therapy. RESULTS Back pain total response rate was 82% (complete or partial response or stable pain, 54, 17, or 11%, respectively). About three-fourths of the patients (76%) achieved full recovery or preservation of walking ability and 44% with sphincter dysfunction improved. Early diagnosis was the most important response predictor so that a large majority of patients able to walk and with good bladder function maintained these capacities. When diagnosis was late, tumors with favorable histologies (i.e., myeloma, breast, and prostate carcinomas) above all responded to RT. Duration of response was also influenced by histology. Favorable histologies are associated to higher median response (myeloma, breast, and prostate carcinomas, 16, 12, and 10 months, respectively). Median survival time was 6 months, with a 28% probability of survival for 1 year. Survival time was longer for patients able to walk before and/or after RT, those with favourable histologies, and females. There was agreement between patient survival and duration of response, systemic relapse of disease being generally the cause of death. CONCLUSION Early diagnosis of MSCC was a powerful predictor of outcome. Primary tumor histology had weight only when patients were nonwalking, paraplegic, or had bladder dysfunction. The effectiveness of RT plus steroids in MSCC emerged in our trial. The most important factors positively conditioning our results were: the high rate of early diagnoses (52%) and the number of tumors with favorable histologies (124 out of 209, 63%) recruited, and the choice of best treatment based on appropriate patient selection for surgery and RT or RT alone.

Abstract
Radiotherapy is effective for most cases of spinal cord compression. Although recurrent spinal cord compression is a common problem, little is known about whether reirradiation preserves neurologic function and what risk of radiation myelopathy it carries. To investigate this question, we reviewed patients at the Mayo Clinic between 1975 and 1992 undergoing two or more courses of radiotherapy to the same segment of the spinal column with radiographically documented epidural disease at the time of reirradiation to determine outcome as measured by the ability to walk and by survival. Fifty-four patients met the study criteria. Radiation doses for the first course ranged from 2,250 to 5,400 cGy (median, 3,000 cGy), and total dose for all courses to the reirradiated spinal segment ranged from 3,650 to 8,089 cGy (median, 5,425 cGy). All patients were ambulatory following the first course of radiation, 40 (74%) were ambulatory at the onset of reirradiation, and 42 (78%) were ambulatory at the end of reirradiation. Thirty-seven patients (69%) remained ambulatory at their last follow-up 6 days to 80 months following reirradiation (median, 4.7 months). Five patients eventually became nonambulatory 6.5 to 35 months following reirradiation. Median survival for all patients following reirradiation was 4.2 months. We conclude that for cancer patients with progressive epidural disease following radiotherapy, reirradiation frequently preserves ambulation and carries minimal risk of radiation myelopathy during the patients' lifetime.

Abstract
Patients with symptomatic spinal metastases and limited life expectancy are often too debilitated to withstand anterior or posterolateral spinal cord decompression and segmental stabilization. More limited surgery aiming solely at preservation or restoration of neurological function and relief from pain offers the potential for significant improvement in the quality of remaining life without incurring undue perioperative morbidity and mortality. Eight patients with spinal metastases and limited life expectancy underwent a unilateral transpedicular decompression procedure on their most symptomatic side and/or the side of maximum tumor involvement. All patients were neurologically improved within the 1st postoperative week; all were ambulatory and continent postoperatively. Postoperatively, all five patients with preoperative motor deficits demonstrated increased motor strength, and the three patients with predominant radicular pain reported marked improvement. There were no perioperative deaths and two transient perioperative complications. The average length of hospitalization was 6 days for patients without complications and 10 days for the entire group. Unilateral transpedicular decompression without stabilization is an effective and safe method for palliating symptomatic spinal metastases in debilitated patients with widespread malignancy and limited life expectancy. This therapeutic option should be considered in select cases as an alternative to either nonoperative management or anterior or posterolateral decompression and segmental stabilization.

Abstract
Approximately 200,000 men will be diagnosed with prostate cancer in 1994. While localized disease is potentially curable with surgery or radiation therapy, metastatic disease is incurable. The most frequent site of metastasis is bone. Spinal cord compression occurs in approximately 7% of men with prostate cancer. Back pain often heralds the diagnosis of spinal cord compression. In prostate cancer patients with back pain or signs of myelopathy or radiculopathy, plain radiographs of the spine and magnetic resonance imaging should be performed. Early diagnosis is of utmost importance. The neurologic status prior to treatment is the major determinant influencing outcome. Following diagnosis, corticosteroid therapy should begin immediately. Hormonal therapy should be instituted in those patients who have not previously undergone hormonal manipulation. The standard approach to definitive therapy is radiation. Surgical decompression plays a role in patients with severe myelopathy, spinal instability, and in those patients whose neurologic status deteriorates during or after radiation therapy.

Abstract
A prospective study of functional assessment of response to palliative radiotherapy (RT) in malignant spinal cord compression (SCC) is reported. The relevant components of the Barthel Activities of Daily Living Index (ADLI: walking, transfer, and bladder and bowel control) were used to assess functional capacity, and compared with a standard neurological assessment. Fifty-one consecutive patients (38 men, 13 women; mean age 63.9 years) were assessed, all of whom were treated by primary or postoperative radiotherapy. Five of the 51 patients had had decompressive laminectomy prior to RT. Median survival was 34 days (range 2-570). Walking improved in only five of 12 patients who had an improvement in motor power. The ability to transfer from bed to chair improved in 11 patients. Ambulation at presentation was the single most important determinant of outcome. Of the eight patients ambulatory at presentation, all were alive at 1 month and seven remained ambulatory. Of the 43 non-ambulatory patients, only four were able to walk following treatment (all prostatic carcinomas). Only four patients regained urinary continence, and none regained bowel control after this was lost. Functional assessment using ADLI and standard neurological examination provide a more useful guide to outcome in malignant SCC than neurological examination alone.

Abstract
Metastatic epidural spinal cord compression (MESCC) is a medical emergency complicating the course of 5-10% of patients with cancer [1]. When diagnosis and treatment is early with the patient ambulatory prognosis for continued ambulation is good [2]. If the patient is nonambulatory or paraplegic, prognosis for meaningful recovery of motor and bladder function is markedly decreased. In the last decade, significant advances in the understanding, management and treatment of metastatic epidural spinal cord compression have occurred. Recent pathophysiological and pharmacological animals studies have afforded insights into disease mechanisms [3-9]. The audit of standard methods of investigation and magnetic resonance imaging have resulted in revision of guidelines for patient evaluation [10-17]. Finally, new surgical philosophies and technical advances have generated interest and controversy [18-25]. With improved clinical awareness, new imaging modalities will help us diagnose epidural spinal cord compression earlier and institute appropriate treatment.

Abstract
We performed a randomised single blind trial of high-dose dexamethasone as an adjunct to radiotherapy in patients with metastatic spinal cord compression from solid tumours. After stratification for primary tumour and gait function, 57 patients were allocated randomly to treatment with either high-dose dexamethasone or no steroidal treatment. Dexamethasone was administered as a bolus of 96 mg intravenously, followed by 96 mg orally for 3 days and then tapered in 10 days. A successful treatment result defined as gait function after treatment was obtained in 81% of the patients treated with dexamethasone compared to 63% of the patients receiving no dexamethasone therapy. Six months after treatment, 59% of the patients in the dexamethasone group were still ambulatory compared to 33% in the no dexamethasone group. Life table analysis of patients surviving with gait function showed a significantly better course in patients treated with dexamethasone (P < 0.05). Median survival was identical in the two treatment groups. Similar results were found in subgroup analysis of 34 patients with breast cancer as the primary malignancy. Significant side-effects were reported in 3 (11%) of the patients receiving glucocorticoids, 2 of whom discontinued the treatment. We conclude that high-dose glucocorticoid therapy should be given as adjunct treatment in patients with metastatic epidural spinal cord compression.

Abstract
PURPOSE To evaluate clinical characteristics and functional outcome of malignant epidural spinal cord compression associated with a paravertebral mass. METHODS AND MATERIALS Between 1987 and 1990, 136 patients with epidural spinal cord compression were treated with irradiation. Of these, 25 patients (18%) had epidural spinal cord compression associated with a paravertebral mass. This report is based on analysis of these 25 patients. Fourteen patients received 3000 cGy in 10 fractions. Seven received 4000 cGy in 16 fractions. Four received 2000 cGy in 5 fractions. Motor function was evaluated by five grades. RESULTS Lung cancer accounted for the majority of epidural spinal cord compression with a paravertebral mass (60%) followed by lymphoma (8%) and kidney tumor (8%). This pattern of epidural spinal cord compression has a longer duration of pain before developing neurologic symptoms and has a high propensity of the upper thoracic spine involvement by an apical lung cancers. The functional outcome of radiation treatment reveals a significant difference between moderately radiosensitive tumors (lung, prostate, cervix, esophagus) and very radiosensitive tumor (lymphoma). None of the nonambulatory patients became ambulatory following radiotherapy except for the very radiosensitive tumors. Higher doses of radiation treatment (4000 cGy in 16 fractions) did not improve functional outcome. CONCLUSION Due to the larger tumor burden, radiation treatment for epidural spinal cord compression associated with a paravertebral mass is not as effective as treatment of epidural spinal cord compression without a paravertebral mass except for the very radiosensitive tumor. Therefore, combined treatment modality might be beneficial for improving functional outcome.

Abstract
Spinal cord compression (SCC) is a relatively uncommon but frequently disabling complication of metastatic breast cancer. We have conducted this retrospective study of 70 patients with SCC secondary to breast cancer with the aims of determining risk factors for its development and predictors of outcome. Median age at diagnosis of breast cancer was 51 years with median time to SCC 42 months. All patients had radiological evidence of bone metastases at the time of SCC, and only five were not known to have bone metastases prior to SCC. The most frequent symptom of SCC was motor weakness (96%) followed by pain (94%), sensory disturbance (79%) and sphincter disturbance (61%). Ninety-one percent of patients had at least one symptom for more than a week. Radiotherapy (RT) was given as primary treatment in 43 cases, whilst 21 had decompressive surgery and seven of these went onto have postoperative radiotherapy. Six patients were deemed too unwell for either modality. Following treatment, 96% of those who were ambulant before therapy maintained the ability to walk. In those unable to walk, 45% regained ambulation, with RT and surgery being equally effective. Median survival following SCC was 4 months, with no significant difference between those treated by RT or surgery. The most important predictor of survival was ability to walk after treatment, followed by time from diagnosis of breast cancer to SCC. We conclude that the majority of patients have warning symptoms of SCC and that nearly all will have evidence of spinal bone metastases before compression occurs. The results suggest that earlier diagnosis and intervention could improve outcome. There was no evidence of benefit from surgery over radiotherapy as primary treatment, survival in both treatment groups being poor.

Abstract
PURPOSE In assessing the effectiveness of the management of metastatic spinal cord or cauda equina compression, we performed a retrospective analysis of 70 patients with this complication whom we treated from 1985 to 1989. METHODS AND MATERIALS The most frequent primary diagnoses in our series were carcinomas of unknown origin and of the breast, lymphoproliferative disease, lung cancer, and prostatic carcinoma. We used the Findlay classification to group all patients according to their pre-therapeutic functional motor status as Grade I (24 patients or 34%), Grade II (27, or 39%) or Grade III (19 or 27%). Treatment consisted of 30-45 Gy of irradiation (using two different schedules) together with high-dose dexamethasone; in only five cases was there surgical intervention. RESULTS We found that a powerful predictor of response to radiotherapy was the patient's neurologic status (Findlay grade) at the time of diagnosis: 66% of previously ambulatory patients remained so, whereas 30% of non-ambulatory patients and only 16% of paraplegic patients regained the ability to walk. Another important predictor of response was primary tumor histology, with the most favorable responses to radiation therapy having been observed in lymphoproliferative diseases and in breast cancer, but with some response in other radiosensitive malignancies as well. CONCLUSION The similarity of our results to those of other centers leads us to conclude that a radiotherapeutic success ceiling of 80% may have been reached for Findlay Grade I patients with metastatic spinal cord compression. In view of this, we suggest that future therapeutic endeavour would be best directed toward early diagnosis of the condition.

Abstract
Fourty-three cases with metastatic spinal cord compression were reviewed post-operatively to clarify the usefulness of the procedures concerning restoration of neurological function, and pain relief. Only patients with pathological spinal instability and neurological sequelae were included. Posterior decompression and stabilization was performed in all but six patients. All but four patients (91%) reported decrease of pain symptoms. Amelioration of neurological function was achieved in 58%. Re-establishment of walking ability was obtained in 57%. Post-surgery life expectancy averaged 11 months. In patients with widespread metastatic disease and/or multi-level instability of the spine restriction to palliative dorsal procedures is sensible. Post-operative ancillary treatment is necessary.

Abstract
In this study we have tried to develop a method to predict the survival and the functional outcome following neoplastic spinal cord injury (SCI), which can be helpful when selecting patients for an intensive inpatient rehabilitation programme. We reviewed the clinical records of all patients with neoplastic epidural spinal cord compression, admitted to any Dutch spinal cord unit (SCU) between 1-1-1985 and 1-1-1990 (n = 74). According to the outcome on 1-1-1991 the average stay at the SCU was 111 days, whereas the average survival after discharge was 423 days. Seven patients died during their stay. Of all of the factors analysed, six showed a positive relationship with prolonged survival (> one year after discharge) and improved functional level: tumour biology (lymphoma, myeloma, breast and kidney tumours); SCI as the presenting symptom of the malignancy; slow (> 1 week) progression rate of neurological symptoms; tumours treated with a combination of surgery and radiotherapy; (partial) bowel control at admission; and (partial) independence regarding transfer activities at admission. A sum score (range 0-6) of these indicators is introduced. A patient with a sum score of 0-1 has zero probability of living longer than one year after discharge and 0.19 of functional improvement during stay at the SCU. A score of 5-6 yields probabilities of 0.77 and 0.92 respectively. We conclude that the sum score can be helpful when selecting patients for an intensive inpatient rehabilitation programme or modifying such a programme. Validation for application in a general hospital is needed.

Abstract
PURPOSE To determine the influence of treatment on ambulancy, pain control and functional outcome of patients with Malignant Spinal Cord Compression. METHODS AND MATERIALS One hundred and thirty-seven patients with Malignant Spinal Cord Compression presenting or referred to the Department of Radiation Oncology, Westmead Hospital between August 1, 1989 and August 1, 1990 were studied prospectively. Patients were treated with palliative radiation therapy alone, surgery followed by radiotherapy or surgery alone. Two patients were not treated. Post-treatment outcome was assessed in terms of ambulatory status, improvement in pain and functional independence using the Functional Independence Measure. RESULTS Thirteen of 16 patients (81%) who were ambulant pre-treatment remained ambulant after treatment. Two of 16 patients (16.5%) who were non-ambulant pre-treatment became ambulant following treatment. Pain improved following treatment in 22 of 30 patients (73%). This benefit was seen equally for ambulant and non-ambulant patients. A high level of functional independence was maintained in patients who remained ambulant. CONCLUSION We conclude that prompt treatment of patients with Malignant Spinal Cord Compression while still able to walk is effective in maintaining ambulancy and functional independence, and that treatment improves pain in most patients.
