Abstract
CASE A 73-year-old male patient presented with a 3-month history of back pain. In bone scintigraphy and the FDG PET-CT scan (fluorodeoxyglucose positron-emission computed tomography), highly suspect uptake levels were found in TH12-L1. Accordingly, an osteodestructive process was found on MRI (magnetic resonance imaging). Following a successfully performed biopsy of TH12, histologic analysis of the bone material revealed a chondrosarcoma (G1; T4N2M0). Complete resection of the tumor was successfully performed, since chondrosarcoma are resistant to radiation and chemotherapy. CONCLUSION As chondrosarcoma is a rare bone neoplasm, it must be considered in the differential diagnosis of lower back pain to initiate adequate treatment.

Individualized assessment of risk and overall survival in patients newly diagnosed with primary osseous spinal neoplasms with synchronous distant metastasis. Front Public Health 2022; 10:955427. [PMID: 36072380 PMCID: PMC9441606 DOI: 10.3389/fpubh.2022.955427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Accepted: 07/28/2022] [Indexed: 01/24/2023] Open
Abstract
Background The prognosis of patients with primary osseous spinal neoplasms (POSNs) presented with distant metastases (DMs) is still poor. This study aimed to evaluate the independent risk and prognostic factors in this population and then develop two web-based models to predict the probability of DM in patients with POSNs and the overall survival (OS) rate of patients with DM. Methods The data of patients with POSNs diagnosed between 2004 and 2017 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate logistics regression analyses were used to study the risk factors of DM. Based on independent DM-related variables, we developed a diagnostic nomogram to estimate the risk of DM in patients with POSNs. Among all patients with POSNs, those who had synchronous DM were included in the prognostic cohort for investigating the prognostic factors by using Cox regression analysis, and then a nomogram incorporating predictors was developed to predict the OS of patients with POSNs with DM. Kaplan-Meier (K-M) survival analysis was conducted to study the survival difference. In addition, validation of these nomograms were performed by using receiver operating characteristic (ROC) curves, the area under curves (AUCs), calibration curves, and decision curve analysis (DCA). Results A total of 1345 patients with POSNs were included in the study, of which 238 cases (17.70%) had synchronous DM at the initial diagnosis. K-M survival analysis and multivariate Cox regression analysis showed that patients with DM had poorer prognosis. Grade, T stage, N stage, and histological type were found to be significantly associated with DM in patients with POSNs. Age, surgery, and histological type were identified as independent prognostic factors of patients with POSNs with DM. Subsequently, two nomograms and their online versions (https://yxyx.shinyapps.io/RiskofDMin/ and https://yxyx.shinyapps.io/SurvivalPOSNs/) were developed. The results of ROC curves, calibration curves, DCA, and K-M survival analysis together showed the excellent predictive accuracy and clinical utility of these newly proposed nomograms. Conclusion We developed two well-validated nomograms to accurately quantify the probability of DM in patients with POSNs and predict the OS rate in patients with DM, which were expected to be useful tools to facilitate individualized clinical management of these patients.

World Neurosurg 2022; 160:e199-e208. [PMID: 34990841 DOI: 10.1016/j.wneu.2021.12.109] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 12/28/2021] [Accepted: 12/29/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Few studies have examined the prognosis for patients with baseline thrombocytopenia undergoing extradural spine tumor resection. OBJECTIVE To evaluate mortality, readmission, and other 30-day outcomes in patients with varying degrees of preoperative thrombocytopenia undergoing osseous extradural tumor excision. METHODS The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried from 2011-2019. Patients were categorized according to baseline preoperative platelet count, in 25,000/μL increments: 125,000-149,000/μL, 100,000-125,000/μL, 75,000-100,000/μL, and < 75,000/μL. These were compared to a control group with platelet count >150,000/μL. Outcomes in each cohort were analyzed using multivariate logistic regression analysis. RESULTS The database search revealed 3,574 patients undergoing extradural tumor resection; 2,171 (4.8%) of patients with platelets 125,000-149,000/μL, 114 (3.2%) with 100,000-125,000/μL, 75,000-100,000/μL in 43 (1.2%), and < 75,000/μL in 42 (1.2%). Platelet counts <100,000/μL was associated with perioperative blood transfusion, cardiac complications, and non-home discharge, and 30-day mortality. On subgroup analysis for mortality, an interaction was present between individuals with moderate/severe thrombocytopenia and cervical tumors. CONCLUSION In patients undergoing surgery for extradural spine tumor, degree of baseline thrombocytopenia-rather than presence alone-is an independent predictor of several adverse events. Wherever possible, optimization of preoperative platelet count to at least 100,000/μL may improve outcomes.

Primary Skull Base Chondrosarcomas: A Systematic Review. Cancers (Basel) 2021; 13:cancers13235960. [PMID: 34885071 PMCID: PMC8656924 DOI: 10.3390/cancers13235960] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Revised: 11/23/2021] [Accepted: 11/25/2021] [Indexed: 12/19/2022] Open
Abstract
Simple Summary Primary skull base chondrosarcomas (SBCs) may carry significant tumor-burden by causing severe cranial nerve neuropathies. Current treatment strategies mainly focus on surgical resection and radiotherapy protocols, with a wide range of findings in terms of efficacy and safety. The aim of our systematic review was to comprehensively analyze the current literature on primary SBCs, describing clinical and radiological characteristics, available management strategies, treatment outcomes, and prognoses. We found that most primary SBCs show benign slow-growing patterns but may cause neurological deficits by compressing critical neurovascular structures. Open surgical approaches favor maximal resection with acceptable complication rates, but only a few studies reported the use of newer endoscopic approaches. Proton-based, photon-based, and carbon-based radiotherapy protocols may also allow safe and effective local tumor control as adjuvant treatments or stand-alone strategies in patients not eligible to undergo surgery. Overall, primary SBCs’ prognoses proved to be favorable and comparable to benign skull base neoplasms. Abstract Background: Primary skull base chondrosarcomas (SBCs) can severely affect patients’ quality of life. Surgical-resection and radiotherapy are feasible but may cause debilitating complications. We systematically reviewed the literature on primary SBCs. Methods: PubMed, EMBASE, Scopus, Web-of-Science, and Cochrane were searched following the PRISMA guidelines to include studies of patients with primary SBCs. Clinical characteristics, management strategies, and treatment outcomes were analyzed. Results: We included 33 studies comprising 1307 patients. Primary SBCs mostly involved the middle-fossa (72.7%), infiltrating the cavernous-sinus in 42.4% of patients. Cranial-neuropathies were reported in 810 patients (62%). Surgical-resection (93.3%) was preferred over biopsy (6.6%). The most frequent open surgical approaches were frontotemporal-orbitozygomatic (17.6%) and pterional (11.9%), and 111 patients (21.3%) underwent endoscopic-endonasal resection. Post-surgical cerebrospinal-fluid leaks occurred in 36 patients (6.5%). Radiotherapy was delivered in 1018 patients (77.9%): photon-based (41.4%), proton-based (64.2%), and carbon-based (13.1%). Severe post-radiotherapy complications, mostly hypopituitarism (15.4%) and hearing loss (7.1%) were experienced by 251 patients (30.7%). Post-treatment symptom-improvement (46.7%) and reduced/stable tumor volumes (85.4%) showed no differences based on radiotherapy-protocols (p = 0.165; p = 0.062). Median follow-up was 67-months (range, 0.1–376). SBCs recurrences were reported in 211 cases (16.1%). The 5-year and 10-year progression-free survival rates were 84.3% and 67.4%, and overall survival rates were 94% and 84%. Conclusion: Surgical-resection and radiotherapy are effective treatments in primary SBCs, with acceptable complication rates and favorable local tumor control.

Zhang Y, He S, Bi Y, Xu Y, Miao W, Wei H. Refractory recurrent spinal chondrosarcoma: What is the role of salvage surgery? Clin Neurol Neurosurg 2021; 210:106999. [PMID: 34739885 DOI: 10.1016/j.clineuro.2021.106999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 10/13/2021] [Accepted: 10/17/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND The spinal chondrosarcoma has high risk of recurrence if the initial surgery is not performed in an en bloc fashion. It remains technically demanding to surgically manage the refractory recurrent spinal chondrosarcoma (RRSC). This study is to assess the clinical features and investigate the prognostic factors for patients with RRSCs. METHODS forty-nine patients with RRSCs underwent salvage surgeries in our institution, and the clinical characteristics were collected and recorded by two independent reviewers. Univariate and multivariate analyses were performed to investigate the independent prognostic factors of recurrence-free survival (RFS) and overall survival (OS) for patients with RRSCs. RESULTS During the mean follow-up of 31.7 ± 21.04 months (Range 9-93), the 3-year RFS and OS rate was 24.5% and 34.5%, respectively. According to the Cox proportional hazards regression model, wide excision with tumor-free margin (>4 mm) was associated with both better RFS and OS for patients with RRSCs. Meanwhile, the number of recurrences ≤2 was beneficial to RFS, while high pathological grade was correlated with worse OS. CONCLUSIONS Wide excision with tumor-free margin (>4 mm) is recommendable if appropriate in the salvage surgery for patients with RRSCs. Patients with number of recurrences ≤ 2 and lower pathological grade may have better RFS and OS, respectively.
