Abstract Introduction: Awake craniotomy (AC) with intraoperative mapping is the best approach to preserve neurological function for glioma surgery in eloquent or near eloquent areas, but whether AC improves the extent of resection (EOR) is controversial. Furthermore, there is less evidence of improved overall survival (OS) in glioma patients. This study aimed to compare the long-term clinical outcomes of glioma resection under AC with those under general anesthesia (GA).Methods: Data of 335 patients who underwent surgery with intraoperative magnetic resonance imaging for newly diagnosed gliomas of World Health Organization (WHO) grades II-IV between 2000 and 2013 were reviewed. EOR and OS were quantitatively compared between the AC and GA groups after 1:1 propensity score matching. The two groups were matched for age, preoperative Karnofsky performance status, tumor location, and pathology based on the WHO 2007 classification.Results: After propensity score matching, 91 pairs were obtained. The median EOR were 96.1% (interquartile range [IQR] 7.3) and 97.4% (IQR 14.4) in the AC and GA groups, respectively (p=0.31). The median survival times were 163.3 months (95% confidence interval [CI] 77.9-248.7) and 143.5 months (95% CI 94.4-192.7) in the AC and GA groups, respectively (p=0.585).Conclusions: Even if the glioma was within or close to the eloquent area, AC was comparable with GA in terms of EOR and OS. In case of difficulties in randomizing patients with eloquent or near eloquent glioma, our propensity score-matched analysis provides retrospective evidence that AC can obtain EOR and OS equivalent to removing glioma under GA.

Abstract Background :We analysed outcomes of cerebral glioblastoma patients undergoing awake craniotomies combined with multimodal techniques for tumour resection, with regards to the extent of resection, functional preservation, and prognosis. Methods : A retrospective analysis was conducted on adult glioblastoma patients who underwent an awake craniotomy from September 2010 to August 2018 under anaesthesia combined with multimodal techniques. Results: In total, 81 glioblastoma patient charts were analysed. The most common lesion sites were the frontal lobe (n=36), temporal lobe (n=17), and parietal lobe (n=6). The main symptoms were headache (n=51), dyskinesia (n=11), speech disorder (n=9), and epilepsy (n=10). The extent of resection was gross total for 91.36% patients, subtotal for 7.41%, and partial for 1.23%. No deaths occurred 30 days post-operation. Intracranial haemorrhage occurred in 2 patients, seizures in 5 patients, and intracranial infections in 3 patients. There was no significant difference between preoperative and postoperative Karnofsky Performance Status scores (P>0.05). There were no significant changes in postoperative neurological function in 50 patients. Symptoms improved in 24 patients. Three patients exhibited motor dysfunction, 2 exhibited speech deficits, and 2 exhibited sensory deficits. The average duration of hospitalization was 6.89±2.66 days. The shortest survival time was 4 months, the longest survival time was 26 months, and the median survival time was 12 months. Conclusions: Awake craniotomy using multimodal techniques such as neuronavigation, intraoperative ultrasound, electrophysiology, and tumour fluorescence during an operation can maximize safety during the cerebral glioblastoma resection, thus protecting brain function and improving surgical efficacy and patients’ postoperative quality of life.

Abstract Background Awake craniotomy (AC) with intraoperative stimulation mapping is the standard treatment for glioma, especially when present on the eloquent cortex. The purpose of this study was to investigate whether functional preservation after AC compromises patient survival as compared with craniotomy under general anesthesia (GA). Methods The medical records of 339 patients who underwent tumor resection surgery for gliomas from January 2010 to December 2014 were retrospectively reviewed. Among these patients, 62 underwent AC with intraoperative stimulation mapping. The primary outcome was the Eastern cooperative oncology group (ECOG) performance score at 3 months postoperatively. Secondary outcomes were the progression-free survival (PFS) and overall survival (OS). A generalized linear model and the Cox proportional hazard model were used to evaluate potential factors influencing general functional status and progression-free survival.Results The newly-diagnosed disease AC and repeat-surgery groups were comparable in terms of sex, age, pathologic grade, extent of resection (EOR) and preoperative Karnofsky Performance Status (KPS). Among the patients with newly-diagnosed disease, the postoperative ECOG score of the AC group was significantly better than that of the GA group. Pathologic grade and the EOR determined the PFS and OS in both the AC and GA groups.Conclusion AC with intraoperative stimulation mapping is safe and allows maximal removal of lesions around the eloquent cortex. Greater preservation of neurologic function may have resulted in a better postoperative general functional status in the AC group.

The Impact

Abstract Maximum safe resection for eloquent glioblastomas (GBMs) is the maximum tumor resection achievable without causing neurological deficits. Although challenging, it must be considered the therapeutic target for GBMs. Indeed, the extension of resection positively correlates with the overall survival and recurrences risk. Awake surgery (AS) has become paramount for achieving maximum safe resection for tumors in eloquent areas. However, there is not a unanimous consensus on the extent of resection of eloquent GBMs, especially for what concerns the so-called supratotal resection (i.e.: resection over the contrast-enhancing limits of the lesion). Recently, several studies focused their attention on the residual tumor volume as estimated from T1-contrast enhanced sequences, but few analyzed the outcomes of patients with a more extended resection. Some authors speculated that increased surgical aggressiveness, thus removing peritumoral edematous area, correlates with improved overall survival and tumor control, without increasing adverse events rates. This study aimed to assess, through quantitative volumetric analysis, the outcomes of a prospectively collected cohort of patients with primary GBM located in eloquent areas. We furtherly subdivided our population into two treatment groups: awake surgery (AS) and general anesthesia (GA) craniotomies. We analyzed the overall outcomes, especially for what concerns MRI T2-Flair signal extent of resection, related to patients’ survival and recurrences formation. Eventually, we stratified our analysis by type of treatment (awake surgery vs. general anesthesia) to rule out any significant differences in survival and postoperative GBMs behaviors. Our data confirmed extensive that T2-Flair resection (EOR≥30%) and AS could improve overall survival and reduce risk of recurrence without, at the same time, causing an increase of surgical and medical complications

Abstract Background In recent years, a correlation of thrombocytosis and a worse prognosis was shown for many solid cancers, including glioblastoma multiforme (GBM). Methods A retrospective review was performed for all patients with a histologically proven and first-diagnosed GBM between 2005 and 2015 in our department. Clinical and paraclinical parameters were acquired from patient documentation and structured for subsequent data analysis. The association of potential risk factors with overall survival was assessed using the Kaplan–Meier survival analysis and Cox regression. Results The present study includes 309 patients first diagnosed with primary GBM. Our analyses validate well-known risk factors of a decreased overall survival such as higher patient age, a larger preoperative tumor volume, Karnofsky performance status, extent of resection, tumor localization, and adjuvant treatment. However, no correlation was observed between a preoperative thrombocytosis, the mean platelet volume, leucocyte count, activated partial thromboplastin time (apTT), fibrinogen level, and acetylsalicylic acid 100 co-medication. Patients with preoperative hemoglobin below 7.5 mmol/L had decreased overall survival. Conclusion The present study, enrolling the largest numbers of patients assessing this topic to date, did not find any association between a preoperative thrombocytosis and overall survival in 309 patients with GBM.

Abstract Objective There are limited data from retrospective studies on whether therapeutic outcomes after regular pancreatectomy are superior to those after enucleation in patients with small, peripheral and well-differentiated non-functional pancreatic neuroendocrine tumors. This study aimed to compare the short- and long-term outcomes of regular pancreatectomy and enucleation in patients with non-functional pancreatic neuroendocrine tumors. Methods Between January 2007 and July 2020, 227 patients with non-functional pancreatic neuroendocrine tumors who underwent either enucleation (n = 89) or regular pancreatectomy (n = 138) were included. Perioperative complications, disease-free survival, and overall survival probabilities were compared. Propensity score matching was performed to balance the baseline differences between the two groups. Results The median follow-up period was 60.76 months in the enucleation group and 43.29 months in the regular pancreatectomy group. In total, 34 paired patients were identified after propensity score matching. The average operative duration in the enucleation group was significantly shorter than that in the regular pancreatectomy group (147.94 ± 42.39 min versus 217.94 ± 74.60 min, P < 0.001), and the estimated blood loss was also significantly lesser (P < 0.001). The matched patients who underwent enucleation displayed a similar overall incidence of postoperative complications (P = 0.765), and a comparable length of hospital stay (11.12 ± 3.90 days versus 9.94 ± 2.62 days, P = 0.084) compared with those who underwent regular pancreatectomy. There were no statistically significant differences between the two groups in disease-free survival and overall survival after propensity score matching. Conclusion Enucleation in patients with non-functional pancreatic neuroendocrine tumors was associated with shorter operative time, lesser intraoperative bleeding, similar overall morbidity of postoperative complications, and comparable 5-year disease-free survival and overall survival when compared with regular pancreatectomy.

Abstract BACKGROUND We evaluated sex-based differences in clinical outcomes and tumor genomics in patients with newly-diagnosed GBM. METHODS We reviewed 665 IDH-wild type GBM patients with Karnofsky Performance Status (KPS) ≥60 treated at our institution from 2010-2019 including; 585 patients with targeted exome sequencing of 447 cancer associated genes (OncoPanel). Deleterious mutations were defined as homozygous deletions or loss of function mutations of known tumor suppressors (as reported in TCGA, ≥ 3 times in the COSMIC database, or predicted as “damaging” in SIFT and/or “probably damaging” in Polyphen 2) or known oncogenic mutations in proto-oncogenes (reported in TCGA or ≥ 3 times in COSMIC). RESULTS There were 384 (57.7%) males and 281 (42.3%) females. Median OS was 22.5 months for females and 19.3 months for males (hazard ratio [HR] 0.81, 95% CI 1.03-1.48, p = 0.02). On multivariable analysis adjusted for age, KPS ≥90, extent of resection, and MGMT methylation status, female sex (adjusted hazard ratio 0.78, 95% CI [0.64-0.95], p = 0.015) was associated with improved OS. Superior OS in females was observed in MGMT-unmethylated patients (HR 0.69, 95% CI [0.54-0.90], p = 0.005) but not MGMT-methylated patients. Thirteen genes were deleteriously altered in ≥5% of our cohort: CDK4 (12.1% male vs. 7.8% female), CDKN2A (46.5% vs. 45.7%), CDKN2B (41.8% vs. 43.3%), EGFR (34.7% vs. 40.0%, MTAP (18.2% vs. 18.8%), NF1 (11.5% vs. 9.4%), PTEN (28.2% vs. 29.8%), TP53 (28.2% vs. 30.2%), RB1 (5.6% vs. 6.5%), MDM4 (6.2% vs. 5.7%), ATM (5.9% vs. 3.7%), MDM2 (7.4% vs. 4.1%), PIK3R1 (6.2% vs. 4.1%). There were no differences in frequency of mutations in these individual genes between males and females (χ 2 [1, N=585] = 0.05-2.86, p = 0.09-0.86). CONCLUSIONS Female sex is associated with improved survival. We did not identify sex-based differences in deleterious genomic alterations amongst commonly altered genes in GBM.

Abstract Background: The benefits of surgical resection (SR) for various Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma (HCC) remain unclear. We investigated the risk factors of overall survival (OS) and survival benefits of SR over nonsurgical treatments in patients with HCC of various BCLC stages.Methods: Overall, 2316 HCC patients were included, and their clinicopathological data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed.Results: In total, 66 (2.8%), 865 (37.4%), 575 (24.8%) and 870 (35.0%) patients had BCLC stage 0, A, B, and C disease, respectively. Furthermore, 1302 (56.2%) of all patients, and 37 (56.9%), 472 (54.6%), 313 (54.4%) and 480 (59.3%) of patients with BCLC stage 0, A, B, and C disease, respectively, died. The median follow-up duration time was 20 (range 0-96) months for the total cohort and was subdivided into 52 (8-96), 32 (1-96), 19 (0-84), and 12 (0-79) months for BCLC stages 0, A, B, and C cohorts, respectively. The risk factors for OS were 1) SR and cirrhosis; 2) SR, cirrhosis, and Child-Pugh (C-P) class; 3) SR, hepatitis B virus (HBV) infection, and C-P class; and 4) SR, HBV infection, and C-P class for the BCLC stage 0, A, B, and C cohorts, respectively. Compared to non-SR treatment, SR resulted in significantly higher survival rates in all cohorts. The 5-year OS rates for SR vs non-SR were 44.0% vs 28.7%, 72.2% vs 42.6%, 42.6% vs 36.2, 44.6% vs 23.5%, and 41.4% vs 15.3% (all p-values<0.05) in the total and BCLC stage 0, A, B, and C cohorts, respectively. After PSM, SR resulted in significantly higher survival rates compared to non-SR treatment in various BCLC stages.Conclusion: SR conferred significant survival benefits to patients with HCC of various BCLC stages and should be considered a recommended treatment for select HCC patients, especially patients with BCLC stage B and C disease.
