Previous studies have shown that microsurgery has two main roles in glioma resection, that is, the nerve function is well protected and the degree of tumor resection is improved. On the basis of this experiment, the curative effect of tumor resection under microscope for glioma was studied based on humanized nursing model. By randomly dividing 64 patients into two steps and comparing them in many aspects, the study mainly obtained two inspirations: microglioma resection has good effect, and humanized nursing mode has good effect on postoperative recovery. Finally, some Suggestions and principles for microglioma resection were put forward: the principle of timely operation after diagnosis, the principle of complete resection for nonfunctional areas, the principle of protection for important functional areas, and the principle of recovery plan confirmed by disease examination after surgery. In addition, in terms of the influence of humanized nursing mode on the treatment of glioma under the microscope, the data statistics and SPSS tests show that humanized nursing mode can effectively improve the satisfaction of patients and their families. Relieve anxiety and depression and help patients recover; Lower scores in pain rating statistics, etc. In addition, this experiment has a good basis for development, and all the 64 patients successfully completed the operation without serious complications, which further verified the above conclusions, namely, the maturity and reliability of the technique of microscopic tumor resection for glioma. The technique of tumor resection under microscope can be used in combination with humanized nursing mode, which has good promotion value.

OBJECTIVEIntraoperative seizures during craniotomy with functional mapping is a common complication that impedes optimal tumor resection and results in significant morbidity. The relationship between genetic mutations in gliomas and the incidence of intraoperative seizures has not been well characterized. Here, the authors performed a retrospective study of patients treated at their institution over the last 12 years to determine whether molecular data can be used to predict the incidence of this complication.METHODSThe authors queried their institutional database for patients with brain tumors who underwent resection with intraoperative functional mapping between 2005 and 2017. Basic clinicopathological characteristics, including the status of the following genes, were recorded: IDH1/2, PIK3CA, BRAF, KRAS, AKT1, EGFR, PDGFRA, MET, MGMT, and 1p/19q. Relationships between gene alterations and intraoperative seizures were evaluated using chi-square and two-sample t-test univariate analysis. When considering multiple predictive factors, a logistic multivariate approach was taken.RESULTSOverall, 416 patients met criteria for inclusion; of these patients, 98 (24%) experienced an intraoperative seizure. Patients with a history of preoperative seizure and those treated with antiepileptic drugs prior to surgery were less likely to have intraoperative seizures (history: OR 0.61 [95% CI 0.38–0.96], chi-square = 4.65, p = 0.03; AED load: OR 0.46 [95% CI 0.26–0.80], chi-square = 7.64, p = 0.01). In a univariate analysis of genetic markers, amplification of genes encoding receptor tyrosine kinases (RTKs) was specifically identified as a positive predictor of seizures (OR 5.47 [95% CI 1.22–24.47], chi-square = 5.98, p = 0.01). In multivariate analyses considering RTK status, AED use, and either 2007 WHO tumor grade or modern 2016 WHO tumor groups, the authors found that amplification of the RTK proto-oncogene, MET, was most predictive of intraoperative seizure (p < 0.05).CONCLUSIONSThis study describes a previously unreported association between genetic alterations in RTKs and the occurrence of intraoperative seizures during glioma resection with functional mapping. Future models estimating intraoperative seizure risk may be enhanced by inclusion of genetic criteria.

Pulmonary fibroelastomas are a rare primary cardiac tumor with less than 50 cases reported in the literature to date. We performed a minimally invasive valve-sparing tumor resection through a left anterior mini-incision (LAMI). The procedure was performed without cardiac arrest or aortic cross clamp, expediting postoperative recovery and allowing for an uncomplicated discharge on postoperative day 5. LAMI is a safe and reliable alternative to median sternotomy for patients requiring interventions on the right ventricular outflow tract and main pulmonary artery, including pulmonary fibroelastoma resection and pulmonary valve replacement when needed.

Abstract BACKGROUND Several studies have proven the benefit of a greater extent of resection on progression-free survival and overall survival in glioblastoma (GBM). Possible reasons for incomplete tumor resection might be wrong interpretation of fading fluorescence or overseen fluorescent tumor tissue by a lacking line of sight between tumor tissue and the microscope. OBJECTIVE To evaluate if an endoscope being capable of inducing fluorescence might overcome some limitations of microscopic fluorescence-guided (FG) resection. METHODS 5-Aminolevulinic acid (20 mg/kg) was given 4 h before surgery. Microsurgical resection of all fluorescent tissue was performed. Then, the resection cavity was scanned with the endoscope. Fluorescent tissue, not being visualized by the microscope, was additionally removed and histopathologically examined separately. Neuronavigation was used for defining the sites of additional tumor resection. All patients underwent magnetic resonance imaging within 48 h after surgery. RESULTS Twenty patients with GBM were operated using microscopic and endoscopic FG resection. In all patients, additional fluorescent tissue was detected with the endoscope. This tissue was completely resected in 19 patients (95%). Eloquent localization precluded complete resection in the remaining patient. In 19 patients (95%), histopathological examination confirmed tumor in the additionally resected tissue. In 19 patients (95%), complete resection was confirmed. In all patients, endoscopic FG resection reached beyond the borders of contrast-enhancing tumor. CONCLUSION Endoscopic FG resection of GBM allows increasing the complete resection rate substantially and therefore is a useful adjunct to microscopic FG resection.

PurposeThe primary objective was to determine the efficacy of a newly designed preoperative chemotherapy regimen in an attempt to improve the cure rate of children with high-risk hepatoblastoma.Patients and MethodsHigh risk was defined as follows: tumor in all liver sections (ie, Pretreatment Extension IV [PRETEXT-IV]), or vascular invasion (portal vein [P+], three hepatic veins [V+]), or intra-abdominal extrahepatic extension (E+), or metastatic disease, or α-fetoprotein less than 100 ng/mL at diagnosis. Patients were treated with alternating cycles of cisplatin and carboplatin plus doxorubicin (preoperatively, n = 7; postoperatively, n = 3) and delayed tumor resection.ResultsOf the 151 patients (150 evaluable for response) 118 (78.7%) achieved a partial response to chemotherapy. Complete resection of the liver tumor could be achieved in 115 patients (76.2%) either by partial hepatectomy (55.6%) or by liver transplantation (20.6%). In 106 children (70.2%), complete resection of all tumor lesions (including metastases) was achieved. Among the patients with initial lung metastases, 52.2% achieved complete remission of the lung lesions with chemotherapy alone. In half of the patients with initial PRETEXT-IV tumor as the only high-risk feature, the tumor could be completely resected with partial hepatectomy. Event-free (EFS) and overall survival (OS) estimates at 3 years were 65% (95% CI, 57% to 73%) and 69% (95% CI, 62% to 77%) for the whole group. EFS and OS for all patients with PRETEXT-IV tumor were 68% and 69%, respectively, and they were 56% and 62%, respectively, for patients with metastasis.ConclusionThe applied treatment rendered a great proportion of tumors resectable, and, in comparison with previously published results, led to an improved survival in patients with high-risk hepatoblastoma.

The Impact

Purpose Although intensive multimodal treatment has improved the prognosis of patients with metastatic neuroblastoma, the impact of primary tumor resection on outcome is a matter of medical debate. Patients and Methods Patients from the German prospective clinical trial NB97 with stage 4 neuroblastoma and age 18 months or older at diagnosis were included. Operation notes and imaging reports were reviewed by two independent experienced physicians. Finally, the extent of tumor resections was correlated with local control rate and outcome. Results A total of 278 patients were included in this study. Image-defined risk factors present at diagnosis were found to be predictive for the extent of tumor resection at first (P < .001) and best (P < .001) operation. No patient died from surgery. Before chemotherapy, complete resection, incomplete resection, and biopsy or no surgery were performed in 6.1%, 5.0%, and 88.5% of patients, respectively. The extent of first operation had no impact on event-free survival (EFS; P = .207), local progression–free survival (LPFS; P = .195), and overall survival (OS; P = .351). After induction chemotherapy, 54.7% of patients underwent complete resection of the primary tumor, 30.6% underwent incomplete resection, and 13.3% had only biopsy or no surgery of the primary tumor. The extent of best operation also had no impact on EFS (P = .877), LPFS (P = .299), and OS (P = .778). Moreover, multivariate analyses showed that surgery did not affect EFS, LPFS, and OS. Conclusion In intensively treated patients with stage 4 neuroblastoma age 18 months or older at diagnosis, surgery of the primary tumor site has no impact on local control rate and outcome.

e14514 Background: Glioblastoma Multiforme (GBM) is the most common primary intracranial tumor. The effect on survival of extent of tumor resection for GBM tumors remains controversial. Our study aims to detect the role of extent of tumor resection in improvement of survival in patients with GBM. Methods: A prospective study for 84 patients with GBM, was conducted between March 2013 and September 2016 in Sohag University Hospital and Sohag Cancer Center. For all of them surgery was done. Either biopsy (stereotactic or open), debulking or gross total resection (complete). All patients received radical radiotherapy concurrent with Temozolomide chemotherapy followed by six to eight cycles of Temozolomide. All patients were followed by clinical examination and brain imaging. Results: 59% of our patients were males and 41% were females. About 78% of the patients had either Eastern Cooperative Oncology Group (ECOG) Performance Status 1 or 2. Median age was 51years with a range (25-70 years). In 38 patients (45.8%) debulking was done, while complete resection was done in 20 patients (24.1%). only biopsy was done in 30% of patients. We found a statistically significant effect for the extent of resection on overall survival (OS)(22 vs 19.5 months) and progression free survival (PFS)(18.25 vs17.42 months) for patients with complete resection vs patients with debulking only. In addition younger age patients had a statistically significant longer survival. Conclusions: Gross total resection (complete resection) of intracranial GBM was associated with longer survival. Gross total resection should be performed whenever possible.

Object Complete resection of skull base meningiomas provides patients with the best chance for a cure; however, surgery is frequently difficult given the proximity of lesions to vital structures, such as cranial nerves, major vessels, and venous sinuses. Accurate discrimination between tumor and normal tissue is crucial for optimal tumor resection. Qualitative assessment of protoporphyrin IX (PpIX) fluorescence following the exogenous administration of 5-aminolevulinic acid (ALA) has demonstrated utility in malignant glioma resection but limited use in meningiomas. Here the authors demonstrate the use of ALA-induced PpIX fluorescence guidance in resecting a skull base meningioma and elaborate on the advantages and disadvantages provided by both quantitative and qualitative fluorescence methodologies in skull base meningioma resection. Methods A 52-year-old patient with a sphenoid wing WHO Grade I meningioma underwent tumor resection as part of an institutional review board–approved prospective study of fluorescence-guided resection. A surgical microscope modified for fluorescence imaging was used for the qualitative assessment of visible fluorescence, and an intraoperative probe for in situ fluorescence detection was utilized for quantitative measurements of PpIX. The authors assessed the detection capabilities of both the qualitative and quantitative fluorescence approaches. Results The patient harboring a sphenoid wing meningioma with intraorbital extension underwent radical resection of the tumor with both visibly and nonvisibly fluorescent regions. The patient underwent a complete resection without any complications. Some areas of the tumor demonstrated visible fluorescence. The quantitative probe detected neoplastic tissue better than the qualitative modified surgical microscope. The intraoperative probe was particularly useful in areas that did not reveal visible fluorescence, and tissue from these areas was confirmed as tumor following histopathological analysis. Conclusions Fluorescence-guided resection may be a useful adjunct in the resection of skull base meningiomas. The use of a quantitative intraoperative probe to detect PpIX concentration allows more accurate determination of neoplastic tissue in meningiomas than visible fluorescence and is readily applicable in areas, such as the skull base, where complete resection is critical but difficult because of the vital structures surrounding the pathology.

Although a primary tenet of neurosurgical oncology is that survival can improve with greater tumor resection, this principle must be tempered by the potential for functional loss following a radical removal. Preoperative planning with functional and physiological imaging paradigms, combined with intraoperative strategies such as cortical and subcortical stimulation mapping, can effectively reduce the risks associated with operating in eloquent territory. In addition to identifying critical motor pathways, these techniques can be adapted to identify language function reliably. The authors review the technical nuances of intraoperative mapping for low- and high-grade gliomas, demonstrating their efficacy in optimizing resection even in patients with negative mapping data. Collectively, these surgical strategies represent the cornerstone for operating on gliomas in and around functional pathways.
