En bloc resection consists in the surgical removal of a vertebral tumor in a single piece with a sufficient margin, to improve survival and reduce recurrence rate. This procedure is technically demanding and correlates with a high complication rate. The purpose of this study is to investigate the risk factors for complications in en bloc resection and evaluate if benefits overcome the risks in term of overall survival. We retrospectively analyzed prospectively collected data of patients treated with en bloc resection between 1980 and 2021. Complications were classified according to SAVES-V2. Overall Survival was estimated using Kaplan-Meier method. A total of 149 patients out of 298 (50%) suffered from at least one complication. Moreover, 220 adverse events were collected (67 intraoperative, 82 early post-operative, 71 late post-operative), 54% of these were classified as grade 3 (in a severity scale from 1 to 6). Ten years overall survival was 67% (95% CI 59–74). The occurrence of relapses was associated to an increased risk of mortality with OR 3.4 (95% CI 2.1–5.5), while complications did not affect the overall survival. Despite a high complication rate, en bloc resection allows for a better control of disease and should be performed in selected patients by specialized surgeons. [ABSTRACT FROM AUTHOR]

Purpose: Chordoma is a low-grade malignant tumor with recurrence and metastasis tendency that originates from embryonic notochordal remnants. The sacrococcygeal region is the most commonly involved site. The aim of this paper is to report the results of the use of cryosurgery in the excision of a giant recurrent sacral chordoma and review of pertinent literature.Methods: A 64 years old female patient with a locally recurrent sacral chordoma came to our attention after ten interventions performed at another institute. A surgical treatment was performed using argon cryosurgery.Results: In this case, it was not possible to perform a marginal or wide excision, but it was intralesional with the removal of three major blocks. The fragments sent for the histological analysis measured total 35 × 30 × 8 cm with a weight of 4.260 g.Conclusions: Given the gelatinous structure of the tumor and the possibility of contamination of operatory field, cryosurgery may be indicated when previous surgeries and the dimensions of tumor mass do not allow a resection with negative margins improving radiotherapy efficacy in the local control of tumor.

Purpose: Metastatic epidural spinal cord compression (MESCC) is radiologically defined as an epidural metastatic lesion causing the displacement of the spinal cord from its normal position in the vertebral canal. The purpose of this paper is the evaluation of the influence of timing of surgery on the chance of neurological recovery.Methods: This is a retrospective observational case-control study performed on patients with MESCC from solid tumors surgically treated at our institute from January 2010 to December 2016. Patients included were divided in two groups depending on surgery that was performed within or after 24 h the admission to the hospital. Neurological status was assessed with American Spine Injury Association (ASIA) Impairment Scale.Results: No statistically significant difference was observed in the variation of ASIA if surgery is performed within or after 24 h from the admission to the hospital. A statistically significant difference was observed after surgery in each group in the improvement of neurological status. A statistically significant difference was reported in the early post-operative complications in patients surgically treated within 24 h.Conclusion: MESCC management is challenge for spine surgeons and may represent an oncologic emergency and if not promptly diagnosed can lead to a permanent neurological damage. According to this study, there is no difference in the chance of neurological recovery if surgery is performed within or after 24 h the admission to hospital, but there is a greater rate of early post-operative complications when surgery is performed within 24 h from the admission to the hospital.

Background: Protocols including combination of surgery and radiotherapy are more and more frequent in the treatment of bone tumors of the spine. In metastatic disease, combination of surgery and radiotherapy is since long time accepted, as based on clinical evidence. In primary tumors, combination of surgery and radiotherapy can be considered in all the cases in which a satisfactory oncological margin cannot be achieved: high-grade malignancies, recurrent tumors, huge tumors expanding in an extracompartimental area, and when tumor-free margin requires unacceptable functional sacrifices. However, metal implants are an obstacle in the collaboration between surgeons and radiation oncologists. Carbon-fiber-reinforced polyethil-ether-ether-ketone (CFR-PEEK) composite implants could make easier and more effective the treatment as radiolucent and not interfering with ionizing radiation and accelerated particles. The purpose of this article is to report the preliminary results from a cohort of patients treated with CFR-PEEK and to evaluate the safety and the non-inferiority of the device respect the commonly used titanium implants.Materials and Methods: This study concerns an ambispective cohort series of 34 tumor patients (14 metastases and 20 primaries, most of them recurrent) submitted to thoracic and lumbar spine fixation with a CFR-PEEK composite implants. Oncologic surgery was palliative decompression and fixation in 9 cases, tumor excision in 21, and enbloc resection in 4. Data collected for this preliminary report were all intraoperative remarks, incidence of complications, changes in neurological status, local control, and survival. All the cases were followed 6-36 months (mean 13 months).Results: Only one intraoperative screw breakage occurred out of 232 implanted screws. Pain control and neurological improvement were the early clinical results. Two sacral screws loosening were found at 9 and 12 months in multilevel constructs performed on multirecurrent tumors. Six local recurrences were early found thanks to the implant radiolucency. Radiation oncologists' opinion was favourable as concerning better treatment planning on CT and lacking of scattering effect during the treatment.Conclusions: No artifacts on imaging studies mean early local recurrence detection. For radiation oncologists, no artifacts on imaging studies mean easier planning and no scattering effect means more effective and safe radiotherapy, particularly when particles are used. Moreover, it seems that the clinical use of CFR-PEEK composite implants may be safe and at least comparable with the commonly used titanium implants in terms of intraoperative complications, stability at weight bearing and at functional recovery. Larger patient series and longer follow-up are required to confirm these data. [ABSTRACT FROM AUTHOR]- Published

Objective: The aim of this study was to evaluate the efficacy and complications of CT-guided radiofrequency ablation (RFA) of spinal osteoid osteoma (OO).Materials and Methods: Between 2002 and 2012, a total of 61 patients (46 male and 15 female, mean age 26.4 ± 12.7 years) were subjected to RFA for spinal OO. The diagnosis of OO was made after a period of pain and symptoms of 20.6 ± 14.4 months. RFA was performed under conscious sedation and local analgesia. Clinical symptoms were evaluated at 3, 6, and12 months, and at the end of the time of the present investigation. Mean follow-up was 41.5 ± 7.1 months.Results: The primary efficacy of RFA, complete regression of symptoms, was obtained in 57 out of 61 patients (93.4%). Four out of 61 (6.5%) patients showed a relapse of OO (after 3 months); 2 out of 4 were subjected to a second RFA, the remaining ones were subjected to surgery. There was one complication (case of lower limb paresthesia for 30 days after the ablation) and one possible complication (a disc herniation).Conclusion: CT-guided RFA is an excellent treatment for spinal OO. Our data suggest that this procedure should be considered for the first stage of therapy for this disease. [ABSTRACT FROM AUTHOR]- Published

Background and Objective En bloc resections aim at surgically removing a tumor in a single, intact piece. Approach must be planned for the complete removal of the tumor without violation of its margins. The shared knowledge of the morbidity, mortality, risk assessment for local disease recurrence, complications, and death, related to spine tumors excised en bloc could improve the treating physician's apprehension of the diseases and decision making process before, during, and after surgical treatment. The purpose of this study was to review and report the experience gained during 25 years in one of the world's biggest spine oncologic centers. Methods A retrospective study of prospective collected data of 1681 patients affected by spine tumors, of whom 220 had en bloc resections performed. Results Most tumors were primary—165 cases (43 benign and 122 malignant); metastases occurred in 55 patients. A total of 60 patients died from the disease and 33 local recurrences were recorded. A total of 153 complications were observed in 100 of 216 patients (46.2%); 64 of these patients (30%) suffered 1 complication, whereas the rest had 2 or more. All complications were categorized according to temporal distribution and severity. These were further divided into 7 groups according to the type of complication. There were 105 major and 48 minor complications. Seven patients (4.6%) died as a result of complications. There were 33 local recurrences (15.28%) recorded. Contaminated cases, surgical margins of the resected tumor—intralesional, marginal, and malignant tumors—were statistically significant independent risk factors for local recurrence of the tumor. Contamination, local recurrence, neoadjuvant radiotherapy, number of levels resected, and metastatic tumors compared with primary malignant tumor were shown to be independent risk factors for a patient's death. Conclusions Treatment of spinal aggressive benign and malignant bone tumors with en bloc resection is beneficial in terms of better local control and prognosis, although it is a highly demanding and risky procedure. Margins are the key point of this procedure, thus a careful preoperative oncologic and surgical staging is necessary to define the optimal surgical approach. The adverse event profile of these surgeries is high. Therefore, it should be performed by experienced and multidisciplinary teams in specialized high volume centers. [ABSTRACT FROM AUTHOR]

Purpose: Identify risk factors, enabling reduction of the rate of complications and improve outcome in en bloc resection surgeries.Methods: A retrospective study of prospective collected data of 1681 patients affected by spine tumors treated from 1990 to 2015 by the same team.Results: A total of 220 en bloc resections that were performed on 216 patients during that period. Most of the tumors were primary-165 cases (43 benign and 122 malignant), metastases occurred in 55 cases. Median FU was 45 months (0-371). 153 complications were observed in 100 patients (46.2 %). 64 (30 %) suffered one complication, while the rest had two or more. There were 105 major and 48 minor complications. Seven patients (4.6 %) died as a result of complications. The combined approach, neoadjuvant chemotherapy and neoadjuvant radiotherapy were statistically significant independent risk factors for complications occurrence. 33 patients (15.2 %) suffered from local recurrence. Reoperations were mostly due to tumor recurrences, but also to hardware failures, wound dehiscence, hematomas and aortic dissection.Conclusion: The rate of complication is higher in multisegmental resections and when double combined approach is performed. Reoperations display greater morbidity owing to dissection through scar/fibrosis from previous operations and possibly from RT. Careful treatment planning and, in the event of uncertainty, referral to a specialty center must be stressed. The high risk of complications should not discourage surgeons from performing en bloc resection when needed. Most of the patients who sustain complications benefit from the better local control resulting from en bloc resection. [ABSTRACT FROM AUTHOR]- Published

Purpose: Chordoma is a rare, locally aggressive neoplasm of the bone that arises from embryonic notochordal remnants. In less than 5 % of cases, chordomas contain a highly malignant sarcomatous component. Because of the rarity of such tumors, little is known about their clinical features and optimal treatment options. Herein, we report two chordoma cases with malignant sarcomatoid areas, consistent with high-grade osteosarcoma in the primary spine lesions, and discuss the presentation and characteristics of this disease.Methods and Results: In both patients, the diagnosis on the first computed tomography (CT)-guided trocar biopsy of the tumor was a conventional chordoma. The two cases represent dedifferentiated chordomas with a sharp demarcation between the conventional chordoma and the high-grade sarcomatous component, which was identified on T2-weighted magnetic resonance imaging (MRI). One patient experienced a symptomatic tumor recurrence 4 months after carbon-ion radiotherapy, and underwent en bloc wide resection of the tumor following chemotherapy. The patient remained well 36 months after surgery without tumor recurrence. The other patient underwent a gross total excision as the second surgery followed by carbon-ion radiotherapy. At the 39-month follow-up, there was no evidence of active disease.Conclusions: Accurate analyses of MRI and positron emission tomography scans should suggest the most representative section for histological assessment. Unlike the treatment of conventional chordomas, the treatment of this disease should include chemotherapy first, followed by en bloc resection and/or carbon-ion radiation.

Study Design: Preliminary report of new antitumor treatment.Objective: To evaluate the effectiveness of electrochemotherapy as a novel treatment of spinal metastasis.Summary Of Background Data: Electrochemotherapy is a new antitumor treatment that combines systemic bleomycin with electric pulses delivered locally at the tumor site. These electric pulses permeabilize cell membranes in the tissue, allow bleomycin delivery diffusion inside the cells, and increase bleomycin cytotoxicity. Previous clinical studies have demonstrated the effectiveness of electrochemotherapy in the treatment of several primary and metastatic solid tumors.Methods: Treatment planning for electrode positioning and electrical pulse parameters was prepared for 4 needle electrodes. Mini-open surgery with a left L5 laminectomy was performed to introduce the eletrodes. The patient was treated according to the established Electrochemotherapy Protocol with Bleomycin. Clinical efficacy of electrochemotherapy was evaluated according to a visual analog scale of pain, Oswestry Disability Index 2.0, the Karnofsky Performance Scale, and Response Evaluation Criteria in Solid Tumors.Results: The assessed follow-up period was 48 months after the electrochemotherapy procedure. Neither serious electrochemotherapy-related adverse events, nor bleomycin toxicity were reported. Overall improvement in pain according to Oswestry Disability Index 2.0 and Karnofsky Performance Scale outcomes was better.Conclusion: Our case represents, to our knowledge, the first one to test the potential role of electrochemotherapy as treatment of spinal metastasis. Electrochemotherapy allowed a successful treatment of metastatic spinal melanoma. However, we believe that there is a strong scientific rationale to support the potential utility of electrochemotherapy as a novel treatment of spinal metastasis, regardless of the histological types.Level Of Evidence: 5.

Purpose: We propose to evaluate the complication rate in minimally invasive stabilization (MIS) for spine fractures and tumors, as a common alternative to open fusion and conservative treatment. Methods: From 2000 to 2010, 187 patients were treated by minimally invasive percutaneous fixation in 133 traumatic fractures and 54 primitive and/or secondary spine tumors. Complications were classified, according to the period of onset as intraoperative and postoperative, and according to the severity, as major and minor. Results: A total of 15 complications (8 %) were recorded: 5 intraoperative (3 %), 6 early postoperative (3 %) and 4 late postoperative (2 %); 6 were minor complications (3 %) and 9 were major complications (5 %). Conclusions: Minimally invasive stabilization of selected spine pathologies appears to be a safe technique with low complication rate and high patient satisfaction. MIS reduces hospitalization and allows a fast functional recovery improving the quality of life. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective review of prospectively collected data.Objective: To evaluate (1) if the segmental resection of the content of the spinal canal could provide an Enneking appropriate tumor-free margin for local control of primary bone tumors surrounding and invading the canal and (2) the safety profile of the segmental resection of the neurostructures.Summary Of Background Data: Treatment outcomes of primary malignant and benign aggressive bone tumors of the spine have been dramatically changed by the application of the musculoskeletal oncologic principles described by Enneking. However, the efficacy of spinal oncology surgery might be limited by unique features of spinal anatomy.Methods: Database search was conducted with the following inclusion criteria: en bloc resection, segmental inclusion of the spinal canal content in the surgical specimen, histologically proven diagnosis, minimum follow-up of 2 years. Exclusion criteria were piecemeal excision of the tumor (debulking) and diagnosis other than primary bone tumors (metastasis, or local extension of extraosseous tumors).Results: A consecutive cohort of eight patients (three men, five women) was available for review. Two patients died within 3 months from the surgery for systemic disease progression or sequelae of the surgery. En bloc resection with segmental spinal canal content inclusion was able to achieve local control of the disease in four out of remaining six cases (66.7%) at an average follow-up of 68.7 months (range 12-174 mo). Three patients in whom local control was achieved are free from disease at an average follow-up of 98.7 months (range 38-174), and one died for systemic disease progression (after 38 mo). Seven out of 8 patients (87.5%) experienced overall 16 complications.Conclusion: En bloc resection including the spinal canal content (spinal amputation) to achieve a tumor-free margin might be considered to perform an Enneking appropriate treatment for motivated patients.Level Of Evidence: 4.
