Abstract Objective Glioblastoma is the most common and most malignant primary brain tumor in adults. The only overall accepted independent prognostic factors are patient age and performance. We ...present a large single institution patient series examined for prognostic factors using uni- and multivariate survival analysis. Methods 492 patients were included who underwent craniotomy for newly diagnosed glioblastoma WHO grade IV between 1990 and 2007 at our department. The association to patient survival was estimated using log-rank test for univariate analysis and cox regression method for multivariate analysis. Results Median patient age was 62 years (mean: 60.4 years, range: 22–93 years), the male: female ratio was 1.26:1. Primary genesis was found in 91.0% of cases. A multifocal tumor was present in 110 cases (22.4%). The median pre- and post-operative Karnofsky Performance Score was 70. Total tumor resection was performed in 288 cases (58.5%), subtotal removal in 134 cases (27.2%). The following parameters were significantly associated with survival in univariate analysis: age, performance, primary genesis, multifocal tumor, neurological deficit, neuropsychological findings, seizures, incidental finding, total or subtotal resection, radiotherapy, chemotherapy, combined radio-/chemotherapy with temozolomide, re-craniotomy, second tumor in patient history. The following parameters were significantly associated with survival in multivariate analysis: age, performance, multifocal tumor, total or subtotal resection, radiotherapy, chemotherapy, combined radio-/chemotherapy with temozolomide. Conclusion In addition to patient age and performance, we identified multiple lesions and resection status as independent prognostic factors. Radiotherapy, chemotherapy and combined radio-/chemotherapy with temozolomide were significantly associated with prolonged survival.

The aim of this study was to examine the impact of surgery on anaplastic astrocytomas (AA), which has not previously been fully elucidated.This was a retrospective study involving a total of 143 patients who underwent surgery for primary AA in our department between 1995 and 2020.METHODSThis was a retrospective study involving a total of 143 patients who underwent surgery for primary AA in our department between 1995 and 2020.Total tumor resection was achieved more often in patients with IDH-mutant tumors (41.09%) than in patients with IDH-wildtype tumors (30.76%). The median PFS was 1876 days for patients with IDH1 mutations and 238 days for patients with IDH-wildtype tumors. The 1-, 3-, 5- and 10-year PFS were longer in patients with total tumor resection and IDH-mutant AA (86.2%, 69%, 65.5% and 44.8%, respectively) than in patients with subtotal tumor resection and IDH-mutant AA (83.3%, 55.6%, 41.7% and 25%, respectively) and even longer compared to all IDH-wildtype tumors. The median OS was 2472 days for patients with IDH1 mutations and 434 days for patients with IDH-wildtype tumors. The 3-, 5- and 10-year OS times were longer in patients with total tumor resection and IDH-mutant AA (89.2%, 85.2% and 72.6%, respectively) than in patients with subtotal tumor resection and IDH-mutant AA (85.9%, 73.7% and 52.6%, respectively) and were even longer compared to all IDH-wildtype tumors.RESULTSTotal tumor resection was achieved more often in patients with IDH-mutant tumors (41.09%) than in patients with IDH-wildtype tumors (30.76%).

Purpose: Interpersonal factors are of major importance for cancer patients' physical and mental health. Brain tumor patients rank amongst those cancer patients with the highest psychosocial burden. ...Changes in language, cognition, and personality pose specific risk factors for impeding interpersonal functioning in this patient group. Despite this, role and relevance of social support including both supportive (e.g., emotional support) and detrimental interactions causing distress (e.g., critical remarks) are not well understood. Aims of this study were thus (1) to investigate the association of social support and patients' Health Related Quality of Life (HRQoL) and (2) to assess whether this relationship is mediated by the patients' disclosure behavior.
Methods: Seventy-four ambulatory brain tumor patients (mean age 54 years; 58% women) completed the following self-report questionnaires: Illness-specific Social Support Scale (SSUK) for assessment of positive support and detrimental interactions, the Disclosure of Trauma Questionnaire (DTQ) for assessment of patients' disclosure behavior, and the Short-Form Health Survey (SF-8) for assessment of QoL.
Findings: Detrimental social interactions were significantly related to patients' mental and physical well-being while positive support was not. Our results support a model in which patients perceiving detrimental social interactions show more difficulties in talking about illness-specific contents in a functional manner. This, in turn, was associated with a lower physical and mental HRQoL.
Conclusions: This was the first study in which the close associations of detrimental social interactions, brain tumor patients' dysfunctional disclosure behavior and patients' mental as well as physical well-being were empiricially validated. Thus, dysfunctional disclosure behavior might pose a relevant therapeutic target when offering psycho-oncological support for brain tumor patients and their families.
Purpose
The aim of this study was to examine the prevalence of comorbid mental disorders as well as the extent of psychosocial distress in patients with intracranial tumours and their partners during ...the early treatment phase. Moreover, we aimed to identify which events are experienced as most distressing in the context of the early diagnosis of brain cancer by patients and spouses.
Methods
Structured clinical interviews for DSM-IV (SCID-IV) were conducted with 26 patients and their partners after the first neurosurgical treatment within the first 3 months after the detection of a brain tumour. Screening measures (NCCN distress thermometer, HADS, IES-R) were used to assess the extent of psychosocial distress as well as anxiety, depression and traumatic stress responses. Distressing experiences were assessed via a structured questionnaire and interview.
Results
Thirty-eight per cent of the patients and 47% of the partners suffered from a psychiatric disorder. Most frequent diagnoses were adjustment disorder and acute stress disorder. The majority of the participants suffered from elevated psychosocial distress. Partners were equally or even more affected than the patients. For the patients, the experience most frequently described as distressing was the first detection of the tumour. The majority of the partners reported to be distressed by the fear of surgery outcomes.
Conclusions
This study revealed that during this very first treatment phase, both brain tumour patients and their spouses show a high prevalence of comorbid mental disorders and psychosocial distress. The findings suggest that research and clinical efforts are needed to address the psychosocial concerns of these populations.
Peritumoral brain edema (PTBE) is a common complication related to intracranial meningiomas. In several studies, researchers have investigated the pathogenesis of PTBE, and the factors involved in ...its development in patients with intracranial meningiomas have been reported. However, very little is known about the clinical effect of PTBE on patients with intracranial meningiomas; therefore, a systematic examination of this matter is necessary.
In this study, we performed a systematic examination of 696 patients with primary intracranial meningiomas to assess the effect of preoperative PTBE on preoperative symptoms, neurological deficits and postoperative complications, and long-term outcomes with a follow-up period of 16.8 years. We performed a univariate analysis and multiple regression for specific outcomes and adjusted for other relevant clinical factors.
A total of 627 (90.1%) patients were symptomatic preoperatively. One hundred eighty-eight (90.8%) patients with small to moderate PTBE and 125 (98.4%) patients with severe PTBE presented with symptoms significantly more often than the 314 (86.7%) patients without PTBE (p < 0.001, univariate analysis). Cognitive deficits, palsy and seizure were significantly more present, preoperatively, in patients with PTBE than in patients without PTBE (p < 0.001, univariate analysis). Two hundred fifty-five (36.6%) patients experienced surgical and systemic complications postoperatively. The complication rate was significantly higher in patients with PTBE; 41.5% for patients with small to moderate PTBE and 52.8% for patients with severe PTBE, compared to 28.2% of patients without PTBE (p < 0.001, univariate analysis). Furthermore, pre- and postoperative KPS scores were significantly lower in patients with PTBE (p < 0.001). Patients with PTBE required additional medical support significantly more often (p < 0.001) and had a significantly longer hospital stay (p < 0.001). The mortality rate was higher in patients with PTBE immediately after surgery and in the follow-up period; however, the difference was not significant. The neurological condition of all patients improved in the follow-up and did not show significant differences between patients with and without preoperative PTBE (p = 0.6361). Multiple logistic regression analyses revealed a significant association between PTBE and the presence of preoperative cognitive deficits, the incidences of seizure and postoperative complications, and low pre- and postoperative KPS scores.
Preoperative PTBE significantly increased the incidences of specific preoperative symptoms, neurological deficits and postoperative complications in patients with intracranial meningiomas. After surgery, patients with preoperative PTBE required medical support significantly more often than patients without PTBE. However, all patients had favorable outcomes after surgery.
According to new hypotheses astrocytomas/gliomas either arise from or attract neural stem cells. Biological markers, particularly antigenic markers, have played a significant role for the ...characterization of these tumour stem cells (TSCc). Because these studies have been performed with single experimental samples mostly from gliomas, we investigated the expression of the stem cell markers CD133/Prominin, Nestin, Sox-2, Musashi-1, CXCR4, Flt-4/VEGFR-3 and CD105/Endoglin in 72 astrocytomas of different WHO-grades and compared it to normal adult human brain. Expression of their mRNA was quantified by quantitative RT-PCR, of their protein by counting immunopositive cells. In contrast to normal brain, tumour samples showed a high variability for the expression of all markers. However, their mean expression was significantly increased in astrocytomas, but this depended on the WHO grade only for CD133, Nestin, Sox-2 and Musashi-1. Confocal microscopy revealed that these markers mostly could be co-stained with glial fibrillary acidic protein, a marker for astoglial cells, but less frequently with the proliferation marker Ki-67/MIB-1. These markers sometimes, but not necessarily could be co-stained with each other in complex patterns. Our results show that most astrocytomas contain considerable portions of cells expressing stem cell markers. It appears that some of these cells originate from tumour genesis (supporting the stem cell hypothesis) while others are attracted by the tumours. Further functional markers are required to differentiate these TSC-types.
Introduction
While surgery is the primary treatment choice for intracranial meningiomas in young patients, surgery in elderly patients, especially those with pre-existing comorbidities, has been the ...subject of repeated discussion. This study investigated the postoperative risks and neurological benefits of meningioma surgery in elderly patients compared to young patients.
Methods
In total, 768 patients were included and divided into two main groups: group I (age: ≤ 64 years; 484 young patients) and group II (age: ≥ 65 years; 284 elderly patients). Group II was subdivided into: IIa (age: 65–69 years), IIb (age: 70–79 years); and IIc (age: ≥ 80 years).
Results
The total tumor resection rate was higher in the elderly cohort than in the young cohort (84.5 and 76.2%, respectively). 154 young patients (31.8%) and 132 elderly patients (46.5%) developed postoperative morbidities, with the three most common being bleeding (12.9%), cranial nerve disorder (10%) and CSF fistula (8.1%). Postoperative bleeding, palsy, speech disorder, pneumonia and renal insufficiency were dependent on age (r = 0.123, p = 0.001; r = 0.089, p = 0.014; r = 0.100, p = 0.006; r = 0.098, p = 0.007 and r = 0.084, p = 0.020) and presented more often in elderly patients. 6 young and 15 elderly patients died during the 17.4-year observation period. Most patients showed a significant improvement in postoperative KPS (p < 0.001), except those over 80 years old (p = 0.753). The KPS at the last follow-up was significantly improved in all patients (p < 0.001).
Conclusion
Meningioma surgery is associated with a higher rate of postoperative complications in elderly patients than in young patients. Most elderly patients, similar to young patients, show a significant improvement in neurological status postoperatively.
Convexity meningiomas (CM) can be successfully treated with neurosurgery. However, clinical complications due to CM have been reported. Moreover, systematic investigations of CM with respect to all ...relevant clinical factors are currently lacking.
We performed a systematic investigation in 210 patients with supratentorial CM considering all relevant clinical and radiological factors, with a follow-up time of 19.5 years.
Among 812 patients with intracranial meningiomas treated in our department (2003–2020), 28.2 % of intracranial meningiomas were located over the supratentorial convexity, and the patients had a median age of 62 years (95 % CI:59–64). The median follow-up was 30.4 months (95 % CI:21.6–37.1). Tumor-related symptoms were observed in 88.1 % of patients. The most common preoperative symptom was headache (28.1 %), followed by seizure (19.5 %). Symptomatic patients had significantly higher tumor volumes than asymptomatic patients (p = 0.0003; 24.5 cm3 and 6.98 cm3, respectively).
Complete tumor resection was achieved in 92.9 % of patients. The most common postoperative complication was bleeding (7.1 %) in the approach area. Of all bleedings, only three were intracerebral hemorrhages and did not require surgical intervention. The second most common complication was postoperative seizure (4.7 %). The multiple logistic regression analyses showed that tumor volume (OR:1.007; 95 % CI:1.001–1.013; p = 0.02) and brain infiltration by the tumor (OR:1.961; 95 % CI:1.028–3.741; p = 0.04) had a significant impact on postoperative complications. The postoperative and final KPS scores significantly improved (p < 0.001). The tumor recurrence rate was 6.2 %, with a median time of 38 months. No surgery-related deaths occurred.
A large tumor volume and brain infiltration by the tumor were significant factors for postoperative complications. The clinical conditions significantly improved postoperatively and further during the follow-up period.
•Most common preoperative symptoms in patients with convexity meningiomas were headache and seizure.•Large tumor volume was a significant factor for preoperative symptoms and postoperative complications.•Bleeding and seizure were two most common postoperative complications.•The postoperative and final KPS significantly improved after tumor resection.•After tumor resections, no surgery-related deaths occurred.
