[Aspects of development of spinal cord compression, neurological status and quality of life in patients with multi-organ tuberculosis].

The authors study features of development of spinal cord compression, neurological affections and quality of life in patients with polyorganic tuberculosis. As shown by examination and treatment of 72 patients having pulmonary and spinal tuberculosis vs 46 control patients with spinal tuberculosis only, patients with pulmonary and spinal tuberculosis demonstrate faster development of spinal cord compression, neurological disorders, more severe and faster loss in motor activity and quality of life than patients with isolated spinal lesion.

Decompression of the spinal cord improves recovery after acute experimental spinal cord compression injury.

The value of decompression after spinal cord injury in patients is still an unresolved issue. It has previously been shown in our laboratory that functional recovery in rats after cord compression varied with both the force and time until decompression. However, the longest duration studied was only 15 minutes, which is far less than that usually encountered in clinical practice, and therefore, the present study was undertaken to determine the value of decompression after more prolonged periods of compression. A factorially designed experiment with five rats per cell was used with the clip compression injury model. Forces of 2.3, 16.9 or 53.0 gms were applied at C7-T1 until decompression was performed after 15, 60, 120, or 240 minutes of compression. Functional recovery was assessed weekly for 8 weeks using the inclined plane technique. Maximum and minimum performance limits were established in normal rats and rats with cord transection, respectively. Univariate analysis and multiple comparison tests were used to analyse the data. The major determinant of recovery was the force of the injury. For example, the animals injured by the 2.3 gm clip performed significantly better than those injured at higher forces for all times until decompression (p less than 0.0001), and there was a significant difference in recovery between the groups injured by the 16.9 and 53.0 gm clips, although only for the 15 minutes until decompression group (p less than 0.05). The time until decompression also affected recovery, but only for the lighter compression forces (2.3 and 16.9 gm). For example, animals decompressed after 60 minutes of 2.3 gm compression recovered significantly better than those decompressed after 240 minutes (p less than 0.05). Thus, if the initial injury force is small, decompression is beneficial even after prolonged injury.

Spondylodiscitis in patients with spinal cord compression: a possible pitfall in radiation oncology.

PURPOSE: In patients presented for spinal irradiation it may be difficult to distinguish between malignant and benign lesions if only plain X-rays and computed tomography (CT)-scans are available. Spinal magnetic resonance imaging (MRI) can be of great diagnostic value. METHODS: From 11/1995 to 05/2000 447 patients were presented for spinal irradiation, 264 beyond regular operating hours. At presentation no spinal MRI was available in 170/447 and 132/264 patients. RESULTS: After spinal MRI, diagnosis was changed from vertebral metastases to spondylodiscitis in 10/170 and 8/132 patients. Six of these patients were already known as cancer patients. CONCLUSION: In patients presented for spinal irradiation spondylodiscitis is not very uncommon. If there is any doubt about metastatic disease as the cause for spinal cord compression a spinal MRI has to be demanded, even beyond regular operating hours.

Urodynamics in the early stages of spinal cord compression from prostate adenocarcinoma.

Acute urinary retention developed in 2 patients with a history of prostate cancer. Urodynamic evaluation revealed autonomic dysfunction, which contrasted with a prior urodynamic study, indicating a possible spinal lesion. Radiographic evaluation led to early diagnosis and treatment of spinal cord compression from metastatic prostate adenocarcinoma. We discuss the diagnostic role of urodynamics in such cases.

Epidural spinal cord compression as an initial symptom in childhood acute lymphoblastic leukemia: rapid decompression by local irradiation and systemic chemotherapy.

We treated an 11-year-old girl with spinal cord compression near an epidural tumor. Bone marrow examination confirmed the diagnosis of acute lymphoblastic leukemia (ALL). To reduce the compression we treated her immediately with high-dose dexamethasone and vincristine administered intravenously along with local irradiation. Three days later, radiation was discontinued because magnetic resonance imaging showed that the spinal cord compression was reduced. Complete remission has continued without evidence of neurologic sequelae for more than 3 years since diagnosis. Rapid reduction of the blasts resulted in tumor lysis syndrome, which was treated with conventional management and additional diuresis without hemodialysis. Epidural spinal cord compression in childhood ALL can be treated effectively with systemic chemotherapy and local radiotherapy without laminectomy.

Role of radiotherapy in the treatment of motor dysfunction due to metastatic spinal cord compression: comparison of three different fractionation schedules.

PURPOSE: The optimum fractionation schedule for radiotherapy (RT) of metastatic spinal cord compression (MSCC) is still debated in the literature. Several reports have compared different fractionation schedules for pain relief. To our knowledge, this retrospective analysis is the first to compare three different schedules for functional outcome. METHODS AND MATERIALS: For posttreatment functional and ambulatory outcome, three schedules, 30 Gy in 10 fractions (n = 93), 37.5 Gy in 15 fractions (n = 80), and 40 Gy in 20 fractions (n = 74), were compared. Motor function was evaluated by a 6-point scale before and at the end of RT and 3, 6, and 12 months later. A multivariate analysis was performed for functional outcome, including fractionation schedule and the three relevant prognostic factors (primary tumor type, time of developing motor deficits before RT, and ambulatory status). RESULTS: No significant difference was observed for posttreatment motor function or ambulatory rates among the three schedules. According to the multivariate analysis, the radiation schedule had no significant impact on functional outcome (p = 0.223) in contrast to the three prognostic factors (p <0.001, p <0.001, and p = 0.012). CONCLUSION: The three fractionation schedules were comparable for functional outcome. The least time-consuming schedule (30 Gy in 10 fractions) should be considered for patients with a markedly reduced life expectancy.

Spinal cord compression by extramedullary hemopoietic tissue in pyruvate-kinase-deficiency-caused hemolytic anemia.

Spinal cord compression by extramedullary hemopoietic tissue is a rare complication of hemolytic anemias. This is the first report of this complication in hemolytic anemia caused by pyruvate-kinase deficiency. Indium scan, computed tomography (CT) scan, and myelography were helpful in diagnosis. Surgery and radiotherapy were followed by complete recovery during a follow-up period of 12 months.

Surgery for cervical spinal cord compression in patients with multiple sclerosis.

OBJECTIVE: The goal of this study was to investigate the clinical and paraclinical features, treatment, and outcomes of patients with multiple sclerosis (MS) and coexisting spinal cord compression secondary to either cervical spondylosis or cervical disc disease. Patients with MS commonly experience neurological disabilities that present as myelopathy associated with bladder dysfunction. For some patients with MS, however, this neurological deterioration may result from coexisting spinal cord compression attributable to either spondylosis or a herniated disc. Overlapping symptoms of the two conditions do not allow clear clinical determination of the underlying cause of worsening. METHODS: Patients with MS who underwent cervical decompression surgery were selected. Medical records were retrospectively reviewed, to collect data on their pre- and postoperative clinical courses. RESULTS: Nine women and five men with definite MS were selected for cervical decompression surgery to treat neurological deterioration considered to be at least partially attributable to spinal cord compression. The most common symptoms were progressive myelopathy (n = 13), neck pain (n = 11), and cervical radiculopathy (n = 10). Bladder dysfunction was notably absent among these patients with MS with moderate disabilities. Surgical intervention was frequently delayed because the neurological deterioration was initially thought to be attributable to MS. The majority of patients experienced either improvement or stabilization of their preoperative symptoms in the immediate postoperative period; three subjects (21%) maintained this improvement after a mean follow-up period of 3.8 years. No MS relapses, permanent neurological worsening, or serious complications resulting from surgery or general anesthesia were noted. CONCLUSION: Carefully selected patients with MS and cervical spinal cord compression secondary to either spondylosis or disc disease may benefit from surgical decompression, with minimal associated morbidity. Clinical features (especially neck pain and cervical radiculopathy) and magnetic resonance imaging may assist clinicians in differentiating between the two conditions and may guide appropriate treatment without undue delay.

Evaluation of five radiation schedules and prognostic factors for metastatic spinal cord compression.

PURPOSE: To study five radiotherapy (RT) schedules and potential prognostic factors for functional outcome in metastatic spinal cord compression (MSCC). PATIENTS AND METHODS: One thousand three hundred four patients who were irradiated from January 1992 to December 2003 were included in this retrospective review. The schedules of 1 x 8 Gy in 1 day (n = 261), 5 x 4 Gy in 1 week (n = 279), 10 x 3 Gy in 2 weeks (n = 274), 15 x 2.5 Gy in 3 weeks (n = 233), and 20 x 2 Gy in 4 weeks (n = 257) were compared for motor function, ambulatory status, and in-field recurrences. The following potential prognostic factors were investigated: age, sex, performance status, histology, number of involved vertebra, interval from cancer diagnosis to MSCC, pretreatment ambulatory status, and time of developing motor deficits before RT. A multivariate analysis was performed with the ordered logit model. RESULTS: Motor function improved in 26% (1 x 8 Gy), 28% (5 x 4 Gy), 27% (10 x 3 Gy), 31% (15 x 2.5 Gy), and 28% (20 x 2 Gy); and posttreatment ambulatory rates were 69%, 68%, 63%, 66%, and 74% (P = .578), respectively. On multivariate analysis, age, performance status, primary tumor, involved vertebra, interval from cancer diagnosis to MSCC, pretreatment ambulatory status, and time of developing motor deficits were significantly associated with functional outcome, whereas the RT schedule was not. Acute toxicity was mild, and late toxicity was not observed. In-field recurrence rates at 2 years were 24% (1 x 8 Gy), 26% (5 x 4 Gy), 14% (10 x 3 Gy), 9% (15 x 2.5 Gy), and 7% (20 x 2 Gy) (P < .001). Neither the difference between 1 x 8 Gy and 5 x 4 Gy (P = .44) nor between 10 x 3 Gy, 15 x 2.5 Gy, and 20 x 2 Gy (P = .71) was significant. CONCLUSION: The five RT schedules provided similar functional outcome. The three more protracted schedules seemed to result in fewer in-field recurrences. To minimize treatment time, the following two schedules are recommended: 1 x 8 Gy for patients with poor predicted survival and 10 x 3 Gy for other patients. Results should be confirmed in a prospective randomized trial.

Surgical approach to epidural spinal cord compression.

NOMS provides a framework to make decisions regarding surgery or radiation in the face of changing technology. NOMS reflects the most important decision points including neurologic, oncologic, mechanical stability, and systemic disease. Currently, patients who have high-grade epidural spinal cord compression (N) from radioresistant disease (O) or demonstrate mechanical instability (M) are offered surgery if they can tolerate it from a systemic (S) standpoint. Patients with radiosensitive tumors (O) are offered external beam radiation regardless of the degree of spinal cord compression (N). Patients with radioresistant tumors (O) who do not have significant spinal cord compression (N) are now offered IGIMRT as the best chance of controlling local tumor and avoiding an operation.

Metastatic spinal cord compression: radiotherapy outcome and dose fractionation.

BACKGROUND AND PURPOSE: No standard dose fractionation has been defined for metastatic spinal cord compression. This retrospective analysis was undertaken to explore the impact of hypofractionated treatment compared to conventional multifraction treatment. MATERIALS AND METHODS: One hundred and two consecutive patients referred to Mount Vernon Cancer Centre with metastatic spinal canal compression confirmed on MR scan in 95% with median age 68 years (range 32-90) and main primary tumour types breast (28%), prostate (28%) and lung (20%); 51% of patients were fully ambulant at diagnosis, 41% ambulant but with paraparesis and 9% had complete paraplegia. Spinal radiotherapy was given delivering a single dose in 32% and 20 Gy in five fractions in 64%. RESULTS: The median survival was 3.5 months; survival was significantly related to primary site and motor function at presentation. Normal ambulation was achieved in 58% at 2 weeks and 71% up to 2 months after treatment. No patient who presented with paraplegia regained function. At presentation 59% of patients had severe pain, which fell to 8% at 2 weeks. Comparing those patients who received one or two dose treatments with those who received protracted fractionation, the two groups were matched for age, sex, primary site and site of compression. Relatively more patients treated with one or two doses had paraplegia; 19% vs. 3%. Despite this outcome in the two groups was equivalent for motor and sphincter function and pain control. CONCLUSIONS: Metastatic spinal canal compression carries a poor prognosis. Urgent treatment will maintain and improve motor function in patients presenting ambulant but those who have paraplegia at presentation do not improve and have a very short survival. In this series no difference in outcome was seen between patients treated with one or two radiation doses compared to multifraction treatment; a randomised trial comparing fractionation schedules would be justified.
