  • Therapeutic approaches for spinal synovial sarcoma: a comprehensive review of the literature. Journal of neurosurgery. Spine Zamarud, A., Shahnoor, S., Maryyum, A., Khan, A. M., Hassan, K. M., Ijaz, A., Sayed, R., Yoo, K., Park, D. J., Chang, S. D. 2024: 1-8

    Abstract

    Synovial sarcoma (SS) is a relatively rare type of soft-tissue sarcoma that is commonly treated with surgery, radiation, chemotherapy, and palliative care. Stereotactic radiosurgery (SRS) is an emerging approach that shows promise in treating CNS conditions, but it has not been studied for SS. The authors present a systematic review that explores the effectiveness of different treatments, with a focus on SRS, for managing spinal SS.A systematic PubMed search was conducted that covered studies from 1964 to 2022, yielding 70 relevant studies. Inclusion criteria encompassed primary and metastatic spinal SS, various treatment modalities, patient age 17 years or older, English-language studies, retrospective series, and case reports. Based on these criteria, 26 studies were included in this review and 44 were excluded.Of the included studies, 15 patients from 9 studies were treated with surgical intervention followed by both conventional radiotherapy (RT) and chemotherapy, 10 patients from 10 studies were treated with surgery followed by RT, 5 studies comprising 8 patients were exclusively treated with surgery, 5 cases in 3 studies were treated with surgery plus concomitant chemotherapy, 4 patients in 2 studies were treated with SRS, and only 1 study reported treatment without surgery and with chemotherapy and RT. The median progression-free survival and overall survival periods observed in the SRS-treated patients were 37 months and 60 months, respectively, which were higher than those of any other treatment method or combination used.The authors' study offers a thorough review of spinal SS treatments. They are hopeful that this will aid clinicians in informed decision-making for better patient outcomes.

  • Surgery and stereotactic radiosurgery for spinal leiomyosarcoma: a single-institution retrospective series and systematic review. Journal of neurosurgery. Spine Zamarud, A., Marianayagam, N. J., Sekar, V., Testa, S., Park, D. J., Yener, U., McCleary, T. L., Yoo, K. H., Emrich, S., Tayag, A., Ustrzynski, L., Pollom, E., Soltys, S., Wang, L., Charville, G., Ganjoo, K., Chang, S.

    Abstract

    Leiomyosarcoma (LMS) is a rare, aggressive soft-tissue sarcoma that seldom spreads to the bone. The spine can be either the site of LMS osseous metastases or the primary tumor site. The optimal treatment option for spinal LMS is still unclear. The authors present a cohort of patients with spinal LMS treated with either upfront surgery or upfront CyberKnife stereotactic radiosurgery (SRS).The authors retrospectively studied the clinical and radiological outcomes of 17 patients with spinal LMS treated at their institution between 2004 and 2020. Either surgery or SRS was used as the upfront treatment. The clinical and radiological outcomes were assessed. A systematic review of the literature was also conducted.Of the 17 patients (20 spinal lesions), 12 (70.6%) were female. The median patient age was 61 years (range 41-80 years). Ten patients had upfront surgery for their spinal lesions, and 7 had upfront CyberKnife radiosurgery. The median follow-up was 11 months (range 0.3-130 months). The median overall survival (OS) for the entire cohort was 13 months (range 0.3-97 months). In subgroup analysis, the median OS was lower for the surgical group (13 months, range 0.3-50 months), while the median OS for the SRS group was 15 months (range 5-97 months) (p = 0.5). Forty percent (n = 4) of those treated with surgery presented with local recurrence at a median of 6.7 months (range 0.3-36 months), while only 14% (n = 1) of those treated with CyberKnife radiosurgery had local recurrence after 5 months. Local tumor control (LTC) rates at the 6-, 12-, and 18-month follow-ups were 72%, 58%, and 43%, respectively, for the SRS group and 40%, 30%, and 20%, respectively, for the surgery group (p < 0.05). The literature review included 35 papers with 70 patients harboring spinal LMS; only 2 patients were treated with SRS. The literature review confirms the clinical and radiological outcomes of the surgical group, while data on SRS are anecdotal.The authors present the largest series in the literature of spinal LMS and the first on SRS for spinal LMS. This study shows that LTC is statistically significantly better in patients receiving upfront SRS instead of surgery. The OS does not appear different between the two groups.

  • Predictors of mortality in chronic subdural hematoma evacuation. Neurosurgical review Sayed, R., Gross, S., Zamarud, A., Nie, L., Mudhar, G., Eikermann, M., Rupp, S., Kim, J., Babar, M., Basam, M., Yassari, R., Gelfand, Y. 2023; 46 (1): 318

    Abstract

    Chronic subdural hematoma (cSDH) is one of the most common types of intracranial hemorrhages, particularly in the elderly. Despite extensive research regarding cSDH diagnosis and treatment, there is conflicting data on predictors of postoperative mortality (POM). We conducted a large retrospective review of patients who underwent a cSDH evacuation at a single urban institution between 2015 and 2022. Data were collected from the electronic medical record on prior comorbidities, anticoagulation use, mental status on presentation, preoperative labs, and preoperative/postoperative imaging parameters. Univariate and multivariate analyses were conducted to analyze predictors of mortality. Mortality during admission for this cohort was 6.1%. Univariate analysis showed the mortality rate was higher in those presenting with a history of dialysis. In addition, those who presented with altered mental status, were intubated, and lower GCS scores had higher rates of POM. Usage of Coumadin was correlated with higher rates of POM. Examination of preoperative labs showed that patients who presented with anemia or thrombocytopenia had higher POM. Imaging data showed that cSDH volume and greatest dimension were correlated with higher rates of POM. Finally, patients that were not extubated postoperatively had higher rates of POM. Multivariate analysis showed that only altered mental status and being not being extubated postoperatively were correlated with a higher risk of mortality. In summation, we demonstrated that altered mental status and failure to extubate were independent predictors or mortality in cSDH evacuation. Interestingly, patient age was not a significant predictor of mortality.

    Abstract

    Glioblastoma (GBM) is the most common primary brain tumor with poor patient prognosis. Spinal leptomeningeal metastasis has been rarely reported, with long intervals between the initial discovery of the primary tumor in the brain and eventual spine metastasis.Here, the authors present the case of a 51-year-old male presenting with 7 days of severe headache, nausea, and vomiting. Magnetic resonance imaging of the brain and spine demonstrated a contrast-enhancing mass in the pineal region, along with spinal metastases to T8, T12, and L5. Initial frozen-section diagnosis led to the treatment strategy for medulloblastoma, but further molecular analysis revealed characteristics of isocitrate dehydrogenase-wild type, grade 4 GBM.Glioblastoma has the potential to show metastatic spread at the time of diagnosis. Spinal imaging should be considered in patients with clinical suspicion of leptomeningeal spread. Furthermore, molecular analysis should be confirmed following pathological diagnosis to fine-tune treatment strategies.

  • The outcome of central nervous system hemangioblastomas in Von Hippel-Lindau (VHL) disease treated with belzutifan: a single-institution retrospective experience. Journal of neuro-oncology Zamarud, A., Marianayagam, N. J., Park, D. J., Yener, U., Yoo, K. H., Meola, A., Chang, S. D. 2023

    Abstract

    Belzutifan is a Hypoxia Inducible Factor 2-alpha inhibitor approved in 2021 by the FDA for the treatment of renal cell carcinoma (RCC) in patients with Von-Hippel Landau (VHL) disease. These patients can also present with central nervous system (CNS) hemangioblastomas (HBs). We aim to study the effectiveness and adverse effects of belzutifan for CNS HBs, by reporting our preliminary institutional experience.We present a series of VHL patients with CNS HBs undergoing treatment with belzutifan for RCC. All the included patients met the RECIST inclusion criteria. The clinical and radiological outcome measures included: Objective response rate (ORR), time-to-response (TTR), adverse events (AE), and patient response. Patient response was classified as partial response (PR), complete response (CR), progressive disease (PD), or stable disease (SD).Seven patients with 25 HBs were included in our study. A belzutifan dose of 120 mg/day PO was administered for a median of 13 months (range 10-17). Median follow up time was 15 months (range 10-24). An ORR of 71% was observed. The median TTR was 5 months (range: 1-10). None of the patients showed CR, while 5 patients (71.4%) showed PR and 2 (28.5%) showed SD. Among patients with SD the maximum tumor response was 20% [increase/decrease] of the lesion diameter. All the patients experienced decreased hemoglobin concentration, fatigue, and dizziness. None of the patients experienced severe anemia (grade 3-4 CTCAE).Belzutifan appears to be an effective and safe treatment for CNS hemangioblastoma in VHL patients. Further clinical trials to assess the long-term effectiveness of the medication are required.

  • Ultrasound guided versus conventional Fluoroscopy guided epidural injection for radiculopathy. A meta-analysis of Randomized Controlled Trials. World neurosurgery Ahmed, M., Ahmad, A., Arshad, M., Naseer, H., Zamarud, A. 2023

    Abstract

    Radiculopathy, a painful condition due to the irritation of a spinal nerve root, is a common neurosurgical presentation. Apart from its conventional treatment with pain killers and surgical management, it can also be managed with epidural steroid injections (ESIs).The objective of this study is to compare ultrasound (USG) guidance with conventional fluoroscopy guidance for ESIs to treat radiculopathy.PubMed, Embase, Clinicaltrials.gov, and Cochrane were systematically searched and RCTs comparing USG with conventional fluoroscopy for ESIs in the case of radiculopathy were included. Web Revman was used for data analysis.The Literature search resulted in 640 studies, of which 7 studies were included in this meta-analysis after extensive screening. There was no statistically significant difference in pain reduction between USG and Fluoroscopy groups especially in the case of lumbosacral spinal level at 1 month [mean difference (MD)-0.12(-0.47-0.23)] and at 3 months [MD 0.73(-1.49, 2.96)]. Similarly, functional improvement after ESIs was comparable between the two groups. The Risk of inadvertent vascular puncture in USG guided ESIs was lower as compared to conventional fluoroscopy guided ESIs [Odds Ratio (OR) 0.21(0.07, 0.64)]. Furthermore, the procedure time in the USG group was also significantly lower as compared to fluoroscopy group.USG guided ESIs are not only comparable to conventional fluoroscopy guided ESIs in terms of pain control and functional improvement, particularly evident at the lumbosacral spinal level, but also have a lower risk of inadvertent vascular puncture.

  • Stereotactic radiosurgery for sarcoma metastases to the brain: a single-institution experience. Neurosurgical focus Zamarud, A., Park, D. J., Dadey, D. Y., Yoo, K. H., Marianayagam, N. J., Yener, U., Szalkowski, G. A., Pollom, E., Soltys, S., Chang, S. D., Meola, A. 2023; 55 (2): E7

    Abstract

    Brain metastases (BMs) secondary to sarcoma are rare, and their incidence ranges from 1% to 8% of all bone and soft tissue sarcomas. Although stereotactic radiosurgery (SRS) is widely used for BMs, only a few papers have reported on SRS for sarcoma metastasizing to the brain. The purpose of this study was to evaluate the safety and effectiveness of SRS for sarcoma BM.The authors retrospectively reviewed the clinical and radiological outcomes of patients with BM secondary to histopathologically confirmed sarcoma treated with SRS, either as primary treatment or as adjuvant therapy after surgery, at their institution between January 2005 and September 2022. They also compared the outcomes of patients with hemorrhagic lesions and of those without.Twenty-three patients (9 females) with 150 BMs secondary to sarcoma were treated with CyberKnife SRS. Median age at the time of treatment was 48.22 years (range 4-76 years). The most common primary tumor sites were the heart, lungs, uterus, upper extremities, chest wall, and head and neck. The median Karnofsky Performance Status on presentation was 73.28 (range 40-100). Eight patients underwent SRS as a primary treatment and 15 as adjuvant therapy to the resection cavity. The median tumor volume was 24.1 cm3 (range 0.1-150.3 cm3), the median marginal dose was 24 Gy (range 18-30 Gy) delivered in a median of 1 fraction (range 1-5) to a median isodose line of 76%. The median follow-up was 8 months (range 2-40 months). Median progression-free survival and overall survival were 5.3 months (range 0.4-32 months) and 8.2 months (range 0.1-40), respectively. The 3-, 6-, and 12-month local tumor control (LTC) rates for all lesions were respectively 78%, 52%, and 30%. There were no radiation-induced adverse effects. LTC at the 3-, 6-, and 12-month follow-ups was better in patients without hemorrhagic lesions (100%, 70%, and 40%, respectively) than in those with hemorrhagic lesions (68%, 38%, and 23%, respectively).SRS, both as a primary treatment and as adjuvant therapy to the resection cavity after surgery, is a safe and relatively effective treatment modality for sarcoma BMs. Nonhemorrhagic lesions show better LTC than hemorrhagic lesions. Larger studies aiming to validate these results are encouraged.

  • Stereotactic radiosurgery for distant brain metastases secondary to esthesioneuroblastoma: a single-institution series. Neurosurgical focus Zamarud, A., Yener, U., Yoo, K. H., Park, D. J., Marianayagam, N. J., Ho, Q. A., Pollom, E., Soltys, S., Wang, L., Chang, S. D., Meola, A. 2023; 55 (2): E6

    Abstract

    Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare, malignant tumor of neuroectodermal origin that arises from the olfactory neuroepithelium. In this study the authors present the first series in the literature on distant brain metastases (BMs) secondary to ENB that were treated with stereotactic radiosurgery (SRS), to evaluate the safety and effectiveness of SRS for this indication.A retrospective analysis of clinical and radiological outcomes of patients with ENB who underwent CyberKnife (CK) SRS at a single center was conducted. The clinical and radiological outcomes of patients, including progression-free survival, overall survival, and local tumor control (LTC) were reported.Between 2003 and 2022, 32 distant BMs in 8 patients were treated with CK SRS at Stanford University. The median patient age at BM diagnosis was 62 years (range 47-75 years). Among 32 lesions, 2 (6%) had previously been treated with surgery, whereas for all other lesions (30 [94%]), CK SRS was used as their primary treatment modality. The median target volume was 1.5 cm3 (range 0.09-21.54 cm3). CK SRS was delivered by a median marginal dose of 23 Gy (range 15-30 Gy) and a median of 3 fractions (range 1-5 fractions) to a median isodose line of 77% (range 70%-88%). The median biologically effective dose was 48 Gy (range 21-99.9 Gy) and the median follow-up was 30 months (range 3-95 months). The LTC at 1-, 2-, and 3-year follow-up was 86%, 65%, and 50%, respectively. The median progression-free survival and overall survival were 29 months (range 11-79 months) and 51 months (range 15-79 months), respectively. None of the patients presented adverse radiation effects.In the authors' experience, SRS provided excellent LTC without any adverse radiation effects for BMs secondary to ENB.

  • Navigating Glioblastoma Diagnosis and Care: Transformative Pathway of Artificial Intelligence in Integrative Oncology. Cureus Ibrahim, M., Muhammad, Q., Zamarud, A., Eiman, H., Fazal, F. 2023; 15 (8): e44214

    Abstract

    Glioblastoma multiforme (GBM), an aggressive brain tumor with high recurrence rates and limited survival, presents a pressing need for accurate and timely diagnosis. The interpretation of MRI can be complex and subjective. Artificial Intelligence (AI) has emerged as a promising solution, leveraging its potential to revolutionize diagnostic imaging. Radiomics treats images as numerical data and extracts intricate features from images, including subtle patterns that elude human observation. By integrating radiomics with genetics through radiogenomics, AI aids in tumor classification, identifying specific mutations and genetic traits. Furthermore, AI's impact extends to treatment planning. GBM's heterogeneity and infiltrative growth complicate delineation for treatment purposes. AI-driven segmentation techniques provide accurate 2D and 3D delineations, optimizing surgical and radiotherapeutic planning. Predictive features like angiogenesis and tumor volumes enable AI models to anticipate postop complications and survival rates. It can also aid in distinguishing posttreatment radiation effects from tumor recurrence. Despite these merits, concerns linger. The quality of medical data, transparency of AI techniques, and ethical considerations require thorough addressing. Collaborative efforts between neurosurgeons, data scientists, ethicists, and regulatory bodies are imperative for AI's ethical development and implementation. Transparent communication and patient consent are vital, fostering trust and understanding in AI-augmented medical care. In conclusion, AI holds immense promise in diagnosing and managing aggressive brain tumors like GBM. Its ability to analyze complex radiological data, integrate genetics, and aid in treatment planning underscores its potential to transform patient care. However, carefully considering ethical, technical, and regulatory aspects is crucial for realizing AI's full potential in oncology.

  • CyberKnife Radiosurgery for Spinal Leptomeningeal Metastases Secondary to Esthesioneuroblastoma: A Clinical Case Report. Cureus Zamarud, A., Yener, U., Sayed, R., Chang, S. D., Meola, A. 2023; 15 (5): e39791

    Abstract

    Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare malignant tumor of neuroectodermal origin that arises from the olfactory epithelium. We present a case of ENB metastasizing through the leptomeningeal route to the spinal dura, which was treated with CyberKnife (CK) stereotactic radiosurgery (SRS), and aim to assess the safety and effectiveness of SRS in such cases. To the best of our knowledge, this is the first case report in the literature that discusses ENB spinal leptomeningeal metastases treated with CK radiosurgery. We retrospectively reviewthe clinical and radiological outcomes in a 70-year-old female with ENB metastasis to the spine. Progression-free survival (PFS), overall survival (OS), and local tumor control (LTC) are investigated. In our patient, ENB had been diagnosedat the age of 58 yearsand spinal metastases had been first noted at the age of 65 years. A total of six spinal lesions received CK SRS. Lesions were present at the level of C1, C2, C3, C6-C7, T5, and T10-11.The median target volume was 0.72 cc (range: 0.32-2.54). A median marginal dose of 24 Gy was delivered to the tumors with a median of three fractions to a median isodose line of 80% (range: 78-81). LTC at the 24-monthfollow-up was 100%. PFS and OS were 27 months and 40 months, respectively. No adverse radiation effects were reported. Even though the treated spinal lesions remained stable, the number of new metastatic lesions had increased with progressive osseous and dural metastatic lesions within the cervical, thoracic, and lumbar spine at the last follow-up. SRS provides relatively good LTC for patients with ENB metastasizing to the spine, with no radiation-induced adverse events.

  • Cyberknife Radiosurgery for Synovial Sarcoma Metastasizing to the Spine: Illustrative Case Reports. Cureus Zamarud, A., Park, D. J., Haider, G., Chang, S. D., Meola, A. 2023; 15 (4): e37087

    Abstract

    Synovial sarcoma (SS) is a rare and aggressive type of soft tissue sarcoma that commonly affects young adults. Metastasis in the spine is a rare complication, and the management of these lesions is challenging. Radiosurgery is an increasingly popular treatment option for spinal metastasis due to its ability to deliver high doses of radiation to the target volume with minimal exposure to surrounding healthy tissues. In this paper, we present two cases of SS with spinal metastasis that were treated with CyberKnife radiosurgery (CKRS). The first case was a 52-year-old female with a history of multiple thoracotomies and lobectomies for lung metastases, who was diagnosed with T6-T8 and T4 spinal metastasis. The second case was a 53-year-old female with Down syndrome, who was diagnosed with T12-L1 spinal metastasis. Both patients experienced an improvement in their symptoms following CKRS treatment and showed stable or decreasing lesion sizes on follow-up imaging. The progression-free survival (PFS) in the first case was 37 months and overall survival (OS) was 79 months. In the second case, the PFS was 12 months and OS was 18 months. These cases highlight the potential benefits of CKRS as a treatment option for SS with spinal metastasis and support its use in the management of this challenging condition.

  • Treatment Outcomes of Leiomyosarcoma Metastasis Affecting the Brachial Plexus: A Comparative Case Report Using Chat Generative Pre-trained Transformer (ChatGPT). Cureus Zamarud, A., Marianayagam, N., Sekar, V., Chang, S. D., Meola, A. 2023; 15 (3): e36715

    Abstract

    Sarcomas are a rare type of cancer that can develop in various parts of the body, including the brachial plexus. Leiomyosarcomas (LMs) are a subtype of sarcoma that develops in smooth muscle tissue and can metastasize to different parts of the body. In this case report, we present two patients with LM metastasized to the brachial plexus, one treated with CyberKnife (Accuray, Sunnyvale, CA) stereotactic radiosurgery (CK SRS) and the other with surgical resection. The aim of this case report is to present the treatment outcomes and adverse effects of CK SRS and surgical resection in brachial plexus LM metastasis. Patient 1 was a 39-year-old female who received CK SRS, and at three months of follow-up, the lesion was smaller, and she reported symptomatic improvement. At 15 months, the lesion was stable in size, and there was no evidence of local invasion of the adjacent vascular structures or nerves. Patient 2 was a 52-year-old male who underwent surgical resection, and at one-month follow-up, the patient was asymptomatic with no recurrence of his symptoms. The size of the residual axillary tumor was stable at three months and showed a slight interval decrease in size at five months of follow-up. He was followed for over 12 months, with no recurrence of his symptoms. Both treatments appear to have been effective in controlling LM growth and relieving symptoms. CK SRS provides a non-invasive option. However, more research is needed to fully understand the effectiveness and safety of these treatments for brachial plexus sarcoma. This case report highlights the importance of considering different treatment options for brachial plexus sarcoma and the need for further studies to understand the best approach for these rare cases.
