Patients and Methods Literature about adult GBM patients with systemic metastasis published before December 31, 2022, was searched in \"PubMed\" and \"Web of Science,\" and the patients' clinical data were collected and compared with those of patients without metastasis to evaluate the risk factors. The molecular pathology results were summarized to evaluate the mechanism. Results One hundred forty-seven patients with metastasis in 113 papers published from 1928 to 2022 were included. Two hundred forty-nine patients without metastasis who underwent surgery in our department in 2017 were included. Comparison of the two groups showed that age ≤ 40 years was significantly correlated with metastasis (HR: 2.086, 95% CI: 1.124-3.871, P=0.020) and better overall survival (HR: 1.493, 95% CI: 1.067-2.083, P=0.019). Molecular pathology results were reported in 39 cases (39/147, 26.5%). The genetic results showed obvious heterogeneity.

Conclusion In young adult GBM patients, especially those ≤ 40 years of age with long survival, attention should be given to the development of systemic metastases.

Screw placement via small incisions reduces the risk of wound healing disorders and blood loss, and patients can be mobilized more quickly and with less pain. In 2022, a cervical minimally invasive stabilization system became available for the complete percutaneous insertion of both cervical pedicle screws and rods. We report on the first results and experiences with this new technology. Methods In this retrospective case series, we included patients with cervical instability treated by minimally invasive percutaneous cervical und upper thoracic spine pedicle screw and rod insertion between August 2022 and August 2023. Intra- and postoperative complications as well as revision surgeries were recorded. The screw position was evaluated by three examiners in the postoperative CT using the Bredow classification. Results Our series includes six male patients (age=56.9±12.9 years; BMI=29.8±9.6 kg/m2). The indication for surgery was trauma, tumor and degenerative stenosis in two patients each. An excellent/good screw position (Bredow 1 and 2) was found in 84.4% of the screws (n = 27/32). None of the screws rated as Bredow 3 (n=2/32) or Bredow 4 (n=3/32) resulted in a neurological deficit or radicular pain and none had to be repositioned. No neurologic complication or revision surgery occurred. As a complication not directly related to the surgery technique, one patient died of a pulmonary lung embolism on the 7th postoperative day. Conclusion The results of this study indicate that minimally invasive percutaneous implantation of a pedicle screw-rod system is also possible in the cervical spine with sufficient accuracy using intraoperative navigation. However, technical details, possible pitfalls and finally careful patient selection must be taken into account.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.

Another issue is if the minimally invasive supraorbital (SO) approach offers the same results compared to the more invasive craniotomy. Aiming to guide approach selection, preoperative grading systems have been described. Method All cases of TSM treated from 2013 to 2018 by extended endoscopic endonasal (EEA) or SO approach have been reviewed and classified according to three preoperative grading system: McDermott scale, Optic Nerve Laterality Score and Yaşargil criteria. Results A total of 15 patients with TSM were treated with the EEA (n=6) or the SO (n=9) approach. Globally, gross total resection was obtained in 87% (n=13) of cases and was higher with the SO (100%, n=9) compared to the EEA (67%, n=4). Visual function improved in all but one patient (n=14). Compared to the EEA group, patients treated by the SO approach had larger tumors (32.3 mm vs 24.5 mm), higher rate of optic canal invasion (4/9 vs 0/6) and arterial encasement (6/9 vs 1/5). Patients with McDermott total point of 1-2 (7/15) were treated mainly by the EEA; all patients with McDermott total score ≥3 (8/15) were treated by the SO approach. All patients with optic canal invasion (4/15) and lateral extension of the tumor (ONL score = 1-3) were treated by the SO approach. Conclusions The SO and EEA are two minimally invasive approaches safe and effective for treating TSM. For tumors with lateral extension (optic nerve laterality score = 1-3), larger diameter (> 30-35 mm), vascular encasement or optic canal involvement (McDermott total point = 2-3), the SO craniotomy is preferred. For small and median tumors with no optic canal invasion or vascular encasement (McDermott total point = 1-2), the EEA represents a valid option.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.
