Int J Oncol 2020; 57:249-263. [PMID: 32319605 PMCID: PMC7252465 DOI: 10.3892/ijo.2020.5045] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 03/30/2020] [Indexed: 12/13/2022] Open
Abstract
Spinal metastasis occurs in 50-75% of bone metastases caused by hepatocellular carcinoma (HCC), and HCC-derived spinal metastasis can lead to a less favorable prognosis. Recently, several studies have demonstrated that C-X3-C motif chemokine ligand 1 (CX3CL1) is closely associated with cancer metastasis, and its secretion is modulated by a disintegrin and metalloproteinase 17 (ADAM17). Bone marrow endothelial cells (BMECs) are an essential component of bone marrow. However, little is known about the roles in and effects of BMECs on HCC spinal metastasis. The present study demonstrated that CX3CL1 and C-X-C motif chemokine receptor 3 (CXCR3) expression was upregulated in HCC spinal metastases, and that CX3CL1 promoted the migration and invasion of HCC cells to the spine. Western blot analysis revealed that the Src/protein tyrosine kinase 2 (PTK2) axis participated in CX3CL1-induced HCC cell invasion and migration. CX3CL1 also increased the expression of M2 macrophage markers in THP-1 monocytes. BMECs promoted the migration and invasion of Hep3B and MHCC97H cells by secreting soluble CX3CL1, whereas the neutralization of CX3CL1 inhibited this enhancement. CX3CL1 enhanced the activation of the phosphatidylinositol-4,5-bisphos-phate 3-kinase catalytic subunit alpha (PIK3CA)/AKT serine/threonine kinase 1 (AKT1) and Ras homolog family member A (RHOA)/Rho associated coiled-coil containing protein kinase 2 (ROCK2) signaling pathways through the Src/PTK2 signaling pathway. Furthermore, ADAM17 was activated by mitogen-activated protein kinase (MAPK) z14 in BMECs and significantly promoted the secretion of CX3CL1. HCC cells enhanced the recruitment and proliferation of BMECs. The overexpression of CX3CR1 facilitated the spinal metastasis of HCC in a mouse model in vivo. In addition, in vivo experiments revealed that BMECs promoted the growth of HCC in the spine. The present study demonstrated that CX3CL1 participates in HCC spinal metastasis, and that BMECs play an important role in the regulation of CX3CL1 in the spinal metastatic environment.

Abstract
Background The optimal EBRT schedule for MSCC is undetermined. Our aim was to determine whether a single fraction (SF) was non-inferior to five daily fractions (5Fx), for functional motor outcome. Methods Patients not proceeding with surgical decompression in this multicentre non-inferiority, Phase 3 trial were randomised to 10 Gy/SF or 20 Gy/5Fx. A change in mobility from baseline to 5 weeks for each patient, was evaluated by a Modified Tomita score: 1 = ‘Walk unaided’, 2 = ‘With walking aid’ and 3 = ‘Bed-bound’. The margin used to establish non-inferiority was a detrimental change of −0.4 in the mean difference between arms. Results One-hundred and twelve eligible patients were enrolled. Seventy-three patients aged 30–87 were evaluated for the primary analysis. The 95% CI for the difference in the mean change in mobility scores between arms was −0.12 to 0.6. Since −0.4 is not included in the interval, there is evidence that 10 Gy/SF is non-inferior to 20 Gy/5Fx. One grade 3 AE was reported in the 5Fx arm. Twelve (26%) patients in the 5Fx arm had a Grade 2–3 AE compared with six (11%) patients in the SF arm (p = 0.093). Conclusion For mobility preservation, one 10-Gy fraction is non-inferior to 20 Gy in five fractions, in patients with MSCC not proceeding with surgical decompression.

Abstract
OBJECTIVE An emerging paradigm for treating patients with epidural spinal cord compression (ESCC) caused by metastatic tumors is surgical decompression and stabilization, followed by stereotactic radiosurgery. In the setting of rapid progressive disease, interruption or delay in return to systemic treatment can lead to a negative impact in overall survival. To overcome this limitation, the authors introduce the use of spinal laser interstitial thermotherapy (sLITT) in association with percutaneous spinal stabilization to facilitate a rapid return to oncological treatment. METHODS The authors retrospectively reviewed a consecutive series of patients with ESCC and spinal instability who were considered to be poor surgical candidates and instead were treated with sLITT and percutaneous spinal stabilization. Demographic data, Spine Instability Neoplastic Scale score, degree of epidural compression before and after the procedure, length of hospital stay, and time to return to oncological treatment were analyzed. RESULTS Eight patients were treated with thermal ablation and percutaneous spinal stabilization. The primary tumors included melanoma (n = 3), lung (n = 3), thyroid (n = 1), and renal cell carcinoma (n = 1). The median Karnofsky Performance Scale score before and after the procedure was 60, and the median hospital stay was 5 days (range 3-18 days). The median Spine Instability Neoplastic Scale score was 13 (range 12-16). The mean modified postoperative ESCC score (2.75 ± 0.37) was significantly lower than the preoperative score (4.5 ± 0.27) (Mann-Whitney test, p = 0.0044). The median time to return to oncological treatment was 5 days (range 3-10 days). CONCLUSIONS The authors present the first cohort of sLITT associated with a percutaneous spinal stabilization for the treatment of ESCC and spinal instability. This minimally invasive technique can allow a faster recovery without prejudice of adjuvant systemic treatment, with adequate local control and spinal stabilization.

Abstract
INTRODUCTION Metastatic epidural spinal cord compression (MESSC) is a frequent event in patients affected by solid tumor metastases. Current available approaches for MESCC include corticosteroids, radiotherapy and surgery. In the last few years, surgery has evolved from decompression by laminectomy alone, with the introduction of instrumentation systems by metalware (screws and hooks), and this has been associated to an improvement of clinical results compared to radiotherapy alone. Areas covered: In this narrative review, we outline the phases of management of cancer patients affected by MESSC, and discuss the timing of treatments, their impact on the Quality of life (QoL), and the relative benefits and harms of surgery and radiotherapy. Expert commentary: Despite the fact that clinical and surgical trials will be required to determine the most appropriate surgical technique and timing of surgery, we do expect a newer and more important role for radiotherapy in the management of MESCC patients in the next future. In particular, the implementation of radiotactic stereosurgery as adjuvant to decompressive surgery is expected to increase in the next few years, above all in those patients that can be candidate to the so called separation surgery.

Abstract
In this study, we evaluate the efficacy of short-course radiotherapy (SCRT) versus long-course radiotherapy (LCRT) in the treatment of metastatic spinal cord compression (MSCC).PubMed, EMBASE, and Web of Science were searched up to April 2015. Relevant data were extracted based on inclusion and exclusion criteria. Methodological quality of randomized controlled trial (RCT) was evaluated using modified Jadad scale; non-RCT was evaluated using Newcastle-Ottawa Scale. Meta-analysis was performed using RevMan 5.3 software.Fourteen studies with 2239 patients were included. Results of meta-analysis showed that there were no significant differences between SCRT and long-course radiotherapy LCRT in 6-month overall survival rate (risk ratio [RR] = 0.97, 95% confidence interval [CI] 0.88, 1.07, P = 0.55), 1-year overall survival rate (RR = 0.94, 95% CI 0.85, 1.04, P = 0.22), motor function improvement (RR = 0.96, 95% CI 0.81, 1.13, P = 0.63), no change on motor function (RR = 0.98, 95% CI (0.88, 1.09), P = 0.74], and deterioration on motor function (RR = 0.96, 95% CI 0.71, 1.31, P = 0.78). Compared with SCRT, LCRT significantly increased 6-month local control rate (RR = 0.87, 95% CI 0.80, 0.95, P = 0.002), 1-year local control rate (RR = 0.83, 95% CI 0.71, 0.97, P = 0.02), and 2-year local control rate (RR = 0.83, 95% CI 0.79, 0.87, P < 0.00001).Both LCRT and SCRT provided similar survival rates and functional outcome, but LCRT showed better local control rates than SCRT. However, considering low cost and good patient's compliance, SCRT may be a better choice.

Abstract
AbstractAimTo investigate the doses given to the kidneys and the small intestines for three radiation therapy techniques [anterior–posterior (APPA) fields, three fields and volumetric-modulated arc therapy (VMAT)] for spinal cord compression (SCC) patients with metastatic disease in the lower thoracic or lumbar spine and to monitor the time spent by clinicians and dose planners.IntroductionRadiation therapy is one of the main treatment modalities for SCC. Typical palliative radiation therapy techniques have used APPA fields or a three-field technique.However, as delivery techniques have evolved dramatically over the past decades, VMAT has gained wide acceptance. VMAT allows for a dose reduction in the organs at risk. Such a dose reduction may result in less toxicity.The use of the VMAT technique may require more time for contouring and planning compared with the APPA and three-field techniques. Any potential dosimetric benefit of VMAT must not be outweighed by large amounts of extra time spent by clinicians and dose planners.Materials and methodsFor 20 patients treated with radiation therapy for SCC at our hospital, we created a VMAT plan, and the more traditionally used APPA and three-field plans. The mean kidney doses and the volume of bowel, which received 20 Gy, were extracted for each plan. The correlations between parameters for three techniques were determined.Furthermore, the time required for contouring targets for five patients; and the time required to plan five patients, was recorded.ResultsVMAT lead to the most conformal distributions: the high-dose areas were restricted to the target volume, whereas the healthy tissue, especially the bowel, received a lower dose. In contrast, the APPA plan lead to a larger volume of bowel being irradiated, whereas the three-field technique spared the bowel at the expense of a higher dose to the kidneys.The average contouring time was 16 minutes, the average planning time was 38 minutes.ConclusionPatients treated for SCC in the lower thoracic or lumbar region may benefit from VMAT treatment, as it reduces the dose to the bowel and kidneys compared with APPA or three-field treatments.

Abstract
SUMMARY: The majority of breast cancer patients will require radiation therapy at some time during the course of their disease. An estimated 30-50% of all radiation treatments are of palliative nature, either to alleviate symptoms or prophylactic to prevent deterioration of quality of life due to locally progressive disease. Radiotherapy is a locally effective tool, and typically causes no systemic and mostly mild acute side effects. The following article provides an overview of options and decision-making in palliative radiotherapy for symptom control.

Abstract
Metastatic spinal cord compression is a frequent medical emergency, and the most common treatment offered is radiotherapy. The routine treatment prescription for spinal cord compression in the UK is 20 Gy in five daily fractions delivered over 1 week. Here, we evaluate the evidence base for the radiotherapy dose for spinal cord compression. Evidence from the four prospective studies conducted so far and retrospective studies does not support a uniform dose of 20 Gy for all patients with spinal cord compression. Available evidence suggests that the radiotherapy dose should be tailored to the individual patient, depending on the subtype of the tumour, the extent of metastatic disease and expected survival. A risk stratification for the optimum dose prescription for patients with spinal cord compression is recommended.

Abstract
PURPOSE In many centers worldwide, radiotherapy for metastatic spinal cord compression (MSCC) is performed with 30 Gy in 10 fractions. This study investigated the potential benefit of dose escalation. METHODS AND MATERIALS Data from 922 patients with carcinomas causing MSCC were retrospectively evaluated. The outcome of 345 patients treated with 10 fractions of 3 Gy in 2 weeks was compared with the outcomes of 577 patients treated with 37.5 Gy in 15 fractions within 3 weeks or 40 Gy in 20 fractions within 4 weeks. Additionally, 10 potential prognostic factors were investigated: age, gender, performance status, tumor type, interval between cancer diagnosis and MSCC, number of involved vertebrae, other bone and visceral metastases, ambulatory status, and the interval to the development of motor deficits before radiotherapy. RESULTS Motor function improved in 19% of patients after 30 Gy in 10 fractions and in 22% after greater doses (p = 0.31). The local control (p = 0.28) and survival (p = 0.85) rates were not significantly different with doses >30 Gy. Better functional outcome was associated with the absence of visceral metastases, an interval between tumor diagnosis and MSCC of >12 months, ambulatory status, and an interval to the development of motor deficits of >7 days. Improved local control was significantly associated with no visceral metastases, improved survival with favorable histologic features (breast or prostate cancer), no visceral metastases, ambulatory status, an interval between cancer diagnosis and MSCC of >12 months, and an interval to the development of motor deficits of >7days. CONCLUSION Escalation of the radiation dose to >30 Gy in 10 fractions did not improve the outcomes in terms of motor function, local control, or survival but did increase the treatment time for these frequently debilitated patients. Therefore, doses >30 Gy in 10 fractions are not recommended.

Abstract
PURPOSE Owing to the aging of the population, the proportion of elderly patients receiving cancer treatment has increased. This study investigated the results of radiotherapy (RT) for metastatic spinal cord compression (MSCC) in the very elderly, because few data are available for these patients. METHODS AND MATERIALS The data from 308 patients aged > or =75 years who received short-course (treatment time 1-5 days) or long-course RT (2-4 weeks) for MSCC were retrospectively analyzed for functional outcome, local control, and survival. Furthermore, nine potential prognostic factors were investigated: gender, performance status, interval from tumor diagnosis to MSCC, tumor type, number of involved vertebrae, other bone or visceral metastases, ambulatory status, and speed at which motor deficits developed. RESULTS Improvement of motor deficits occurred in 25% of patients, with no further progression of MSCC in an additional 59%. The 1-year local control and survival rate was 92% and 43%, respectively. Improved functional outcomes were associated with ambulatory status and slower developing motor deficits. Improved local control resulted from long-course RT. Improved survival was associated with a longer interval from tumor diagnosis to MSCC, tumor type (breast/prostate cancer, myeloma/lymphoma), lack of visceral or other bone metastases, ambulatory status, and a slower development of motor deficits. CONCLUSION Short- and long-course RT are similarly effective in patients aged > or =75 years regarding functional outcome and survival. Long-course RT provided better local control. Patients with better expected survival should receive long-course RT and others short-course RT. The criteria for selection of an appropriate regimen for MSCC in very elderly patients should be the same as for younger individuals.

Abstract
PURPOSE Patients with cancer of unknown primary (CUP) account for about 10% of patients with metastatic spinal cord compression (MSCC). This study aims to define the appropriate radiation regimen for these patients. METHODS AND MATERIALS Data of 143 CUP patients irradiated for MSCC were retrospectively evaluated. Short-course radiotherapy (RT) (1x8 Gy, 5x4 Gy, n = 68) and long-course RT (10x3 Gy, 15x2.5 Gy, 20x2 Gy, n = 75) plus 8 further potential prognostic factors (age, gender, performance status, visceral metastases, other bone metastases, number of involved vertebrae, ambulatory status, time of developing motor deficits before RT) were compared for functional outcome and survival. RESULTS Improvement of motor function occurred in 10% of patients, no further progression of motor deficits in 57%, and deterioration in 33%. On multivariate analysis, functional outcome was positively associated with slower development of motor deficits (p < 0.001), absence of visceral metastases (p = 0.008) and other bone metastases (p = 0.027), and ambulatory status (p = 0.054), not with the radiation regimen (p = 0.74). Recurrence of MSCC in the irradiated region occurred in 7 patients after median 6 months. Median survival was 4 months. On multivariate analysis, better survival was significantly associated with absence of visceral metastases (p < 0.001), absence of other bone metastases (p = 0.005), ambulatory status (p = 0.001), and slower development of motor deficits (p = 0.030). CONCLUSIONS For MSCC treatment in patients with CUP, no significant difference was observed between short-course and long-course RT regarding functional outcome and survival. Short-course RT appears preferable, at least for patients with a poor predicted survival, as it is more patient convenient and more cost-effective.

Abstract
OBJECTIVE For MSCC treatment, a short treatment time is desirable, especially if survival prognosis is poor. Survival depends on the primary tumor, extent of disease, performance status, ambulatory status, and the number of involved vertebrae. These factors may help to define the appropriate regimen for the individual patient. Our study compares short-course (1 x 8 Gy, 5 x 4 Gy) and long-course RT (10 x 3 Gy, 15 x 2.5 Gy, 20 x 2 Gy) for functional outcome in MSCC patients with renal cell carcinoma. METHODS The following potential prognostic factors for functional outcome were retrospectively investigated: age, performance status, involved vertebra, ambulatory status, time of developing motor deficits before RT, radiation schedule (short-course RT, n=37; long-course RT, n=50). RESULTS Eighty-seven patients were included in this retrospective study, 25 patients (29%) showed improvement of motor function, 52 patients (60%) no change, 10 patients (11%) deterioration. 25% of non-ambulatory patients became ambulatory after RT. Functional outcome was affected by the time of developing motor deficits before RT (p<0.001). The RT schedule had no significant impact (p=0.91). In the short-course RT sub-group, functional outcome was similar for 1 x 8 Gy and 5 x 4 Gy (p=0.99). CONCLUSION Short-course and long-course RT appear similarly active for MSCC in patients with renal cell carcinoma. Short-course RT appears preferable, as it is means less patient discomfort. Because 1 x 8 Gy and 5 x 4 Gy were comparably effective, 1 x 8 Gy may be suggested the best actual choice.

Prognostic factors predicting functional outcomes, recurrence-free survival, and overall survival after radiotherapy for metastatic spinal cord compression in breast cancer patients. Int J Radiat Oncol Biol Phys 2005; 64:182-8. [PMID: 16198069 DOI: 10.1016/j.ijrobp.2005.06.036] [Citation(s) in RCA: 48] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2005] [Accepted: 06/10/2005] [Indexed: 11/18/2022]
Abstract
PURPOSE To identify significant prognostic factors after irradiation of metastatic spinal cord compression (MSCC) in 335 breast cancer patients. METHODS AND MATERIALS The potential prognostic factors investigated included involved vertebra, other bone metastases, visceral metastases, performance status, pretreatment ambulatory status, time until motor deficits developed before RT, radiation schedule (shorter-course RT [one fraction of 8 Gy/five fractions of 4 Gy] vs. longer-course RT [10 fractions of 3 Gy/15 fractions of 2.5 Gy/20 fractions of 2 Gy), and the response to RT. RESULTS On multivariate analysis, better functional outcome was associated with slower development of motor deficits (p <0.001) and being ambulatory before RT (p <0.001). The overall recurrence rate of MSCC was greater if other bone metastases were present (p <0.001) and if shorter-course RT was used (p <0.001). In-field recurrences alone were more frequent after shorter-course RT (p = 0.008). Survival was negatively affected by the presence of visceral metastases (p <0.001), deterioration of motor function after RT (p <0.001), reduced performance status (p <0.001), and the rapid development of motor deficits (p = 0.044). CONCLUSION Outcomes and survival after RT for MSCC in breast cancer patients are associated with several prognostic factors. Patients with poor expected survival may be treated with shorter-course RT to keep the overall treatment time short. If survival is expected to be relatively favorable, longer-course RT appears preferable, because it is associated with fewer MSCC recurrences.
