Abstract Primitive IMT represent 8-10% of all primary tumors of the spinal cord. Only 2- 4% of all CNS tumors in adults are IMT. Adult astrocytomas are 25-35% of total IMT (1). We prospectively analyzed clinical, imaging and pathological data from all consecutive patients operated for intramedullary tumors in our department (Neurosurgery I Clinic, Ward II) between January 2003 and August 2009 (80 months). All surgical interventions were performed by the same surgical team. We emphasized the technical difficulties raised by ablation of IMT depending on the type of the tumor and postoperative neurological outcome.

Objective. To determine the dynamics and state of neurosurgical care for tumors of the spinal cord and spine (TSCS) in Ukraine. Materials and methods. The work is based on the analysis of hospitalizations and surgical treatment of patients with TSCS in neurosurgical departments of Ukraine in 2000-2019. Results. In 2019, 1,325 patients with TSCS were hospitalized in neurosurgical departments of Ukraine, which is 2,3 times more than in 2000 (567), per 1 million population - almost 3 times (34,7 vs. 11, 6 ). Over 20 years, the number of operated patients increased 2,8 times (from 385 to 1079), per 1 million population - 3,6 times (from 7,9 to 28,3), there was an increase in surgical activity by 20% (from 67,9 to 81,4%), a decrease in the general and postoperative mortality - twice (from 2,6 to 1,2% and from 2,6 to 1,3% respectively). Patients with TSCS account for 1,5% of all patients hospitalized in neurosurgical departments of Ukraine, 12,8% of all CNS neoplasms and 5,2% of all spinal pathology. Vertebral tumors account for 42,64% of all TSCS and extramedullary tumors have an incidence rate similar to vertebral tumors (42,64%), intramedullary tumors account for 14,72%. In 2019, 74.4% more patients with extramedullary tumors were hospitalized than in 2000 (565 and 324 respectively), and 84.5% more were operated on (463 and 251 respectively). The rate of increase is even higher per 1 million population. In 2019, there were 14.8 hospitalizations per 1 million population for extramedullary tumors, which is 2.2 times greater than in 2000 (6,6 hospitalizations), and 12,1 operations, which is 2,4 times greater than in 2000 (5,1 operations). In 2019, patients with intramedullary tumors were hospitalized 2,2 times more than in 2000. (195 and 89 respectively), were operated 2,5 times more (151 and 61 respectively). The rate of increase is even 4higher per 1 million population. In 2019, there were 5,1 hospitalizations for intramedullary tumors per 1 million population, which is 2,8 times greater than in 2000 (1,8 hospitalizations), and 4,0 operations, which is 3,2 times greater than in 2000 (1,2 operations). In 2019, patients with vertebral tumors were hospitalized 3.7 times more than in 2000 (565 and 154 respectively), were operated 6,4 times more (465 and 73 respectively). The rate of increase is even higher per 1 million population. In 2019, there were 14,8 hospitalizations per 1 million population for vertebral tumors, which is 4,7 greater than in 2000 (3,1 hospitalizations), and 12,2 surgeries, which is 8,2 greater than in 2000 (1,5 operations). Сonclusions. The introduction of modern neuroimaging methods and advanced treatment methods into clinical practice has contributed to an increase in the number of hospitalizations and surgical interventions in TSCS.

Object. The extension of stereotactic radiosurgery treatment of tumors of the spine has the potential to benefit many patients. As in the early days of cranial stereotactic radiosurgery, however, dose-related efficacy and toxicity are not well understood. The authors report their initial experience with stereotactic radiosurgery of the spine with attention to dose, efficacy, and toxicity. Methods. All patients who underwent stereotactic radiosurgery of the spine were treated using the Novalis unit at Westchester Medical Center between December 2001 and January 2004 are included in a database consisting of demographics on disease, dose, outcome, and complications. A total of 31 patients (12 men, 19 women; mean age 61 years, median age 63 years) received treatment for 35 tumors. Tumor types included 26 metastases (12 lung, nine breast, five other) and nine primary tumors (four intradural, five extradural). Thoracic tumors were most common (17 metastases and four primary) followed by lumbar tumors (four metastases and four primary). Lesions were treated to the 85 to 90% isodose line with spinal cord doses being less than 50%. The dose per fraction and total dose were selected on the basis of previous treatment (particularly radiation exposure), size of lesion, and proximity to critical structures. Conclusions. Rapid and significant pain relief was achieved after stereotactic radiosurgery in 32 of 34 treated tumors. In patients treated for metastases, pain was relieved within 72 hours and remained reduced 3 months later. Pain relief was achieved with a single dose as low as 500 cGy. Spinal cord isodoses were less than 50% in all patients except those with intradural tumors (mean single dose to spinal cord 268 cGy and mean total dose to spinal cord 689 cGy). Two patients experienced transient radiculitis (both with a biological equivalent dose (BED) > 60 Gy). One patient who suffered multiple recurrences of a conus ependymoma had permanent neurological deterioration after initial improvement. Pathological evaluation of this lesion at surgery revealed radiation necrosis with some residual/recurrent tumor. No patient experienced other organ toxicity. Stereotactic radiosurgery of the spine is safe at the doses used and provides effective pain relief. In this study, BEDs greater than 60 Gy were associated with an increased risk of radiculitis.

Most sporadic peripheral nerve sheath tumors in adults are schwannomas. These tumors usually present with significant pain but can also cause neurological deficits. Symptomatology is diverse, and successful surgical interventions demand interdisciplinarity. We retrospectively reviewed 414 patients treated between 2006 and 2017 for peripheral nerve sheath tumors. We analyzed clinical signs, symptoms, histology, and neurological function in the cohort of adult patients with schwannomas without a neurocutaneous syndrome. In 144 patients, 147 surgical interventions were performed. Mean follow-up was 3.1 years. The indication for surgery was pain (66.0%), neurological deficits (23.8%), significant tumor growth (8.8%), and suspected malignancy (1.4%). Complete tumor resection was achieved on 136/147 occasions (92.5%). The most common location of the tumors was intraspinal (49.0%), within the cervical neurovascular bundles (19.7%), and lower extremities (10.9%). Pain and neurological deficits improved significantly (p ≤ 0.003) after 131/147 interventions (89.1%). One patient had a persistent decrease in motor function after surgery. Complete resection was possible in 67% of recurrent tumors, compared to 94% of primary tumors. There was a significantly lower chance of complete resection for schwannomas of the cervical neurovascular bundle as compared to other locations. The surgical outcome of sporadic schwannoma surgery within the peripheral nervous system is very favorable in experienced peripheral nerve surgery centers. Surgery is safe and effective and needs a multidisciplinary setting. Early surgical resection in adult patients with peripheral nerve sheath tumors with significant growth, pain, neurological deficit, or suspected malignancy is thus recommended.

Abstract The field of spinal oncology has substantially evolved over the past decades. This review synthesizes and appraises what was learned and what will potentially be discovered from the recently completed and ongoing clinical studies related to the treatment of primary and secondary spinal neoplasms. This scoping review included all clinical studies on the treatment of spinal neoplasms registered in the ClinicalTrials.gov website from February/2000 to December/2020. The terms “spinal cord tumor”, “spinal metastasis”, and “metastatic spinal cord compression” were used. Of the 174 registered clinical studies on primary spinal tumors and spinal metastasis, most of the clinical studies registered in this American registry were interventional studies led by single institutions in North America (n=101), Europe (n=43), Asia (n=24) or other continents (n=6). The registered clinical studies mainly focused on treatment strategies for spinal neoplasms (90.2%) that included investigating stereotactic radiosurgery (n=33), radiotherapy (n=21), chemotherapy (n=20), and surgical technique (n=11). Of the 69 completed studies, the results from 44 studies were published in the literature. In conclusion, this review highlights the key features of the 174 clinical studies on spinal neoplasms that were registered from 2000 to 2020. Clinical trials were heavily skewed towards the metastatic population as opposed to the primary tumours which likely reflects the rarity of the latter condition and associated challenges in undertaking prospective clinical studies in this population. This review serves to emphasize the need for a focused approach to enhancing translational research in spinal neoplasms with a particular emphasis on primary tumors.

BACKGROUND: Primary spinal cord intramedullary tumors are rare and present with insidious symptoms. Previous treatment protocols emphasized biopsy and radiation/chemotherapy but more aggressive protocols have emerged. OBJECTIVE: To report our experience. METHOD: Forty-eight patients were diagnosed with primary intramedullary tumors. The cervical cord was involved in 27% and thoracic in 42% of patients. Complete microsurgical removal was attempted whenever possible without added neurological morbidity. RESULTS: Complete resection was obtained in 33 (71%) patients. Neurological function remained stable or improved in 32 patients (66.7%). Ependymoma was the most frequent tumor (66.7%). CONCLUSION: Neurological outcome is superior in patients with subtle findings; aggressive microsurgical resection should be pursued with acceptable neurological outcomes.

Actuality. To date, there are few publications focused on pneumovesicoscopic ureteral reimplantation in young children. The article is devoted to surgical interventions in this age group. Material and methods. Surgical interventions on small volume bladder have significant technical difficulties. The authors assessed potentials for performing pneumovesicoscopic ureteral reimplantation by the Cohen technique in 14 children under 2 with various obstructive uropathies. Results. In all children, surgical interventions were performed according to preoperative plans. There were no conversions to an open procedure. As it has been found out, patient’s age and bladder volume were not limiting factors for this type of intervention. Conclusion. The pneumovesicoscopic ureteral reimplantation in young children is a hi-tech procedure which requires a unique equipment and a highly qualified surgical team. To reduce the procedure duration, further experience and more information are needed.
