Second surgery for relapsed glioblastoma: an observational study on criteria for patient selection in real life.

Aim: There is little consensus on salvage management of glioblastoma after recurrence, for lack of evidence. Materials & methods: A retrospective study of treatments in patients with recurrent glioblastoma. Results: Surgery at recurrence was related to better overall survival (OS) and progression-free survival (PFS). Surgery at recurrence, Karnofsky index, MGMT methylation status, younger age at diagnosis and number of chemotherapy cycles were positive factors for OS and PFS. The benefit of OS was relevant for a second surgery performed at least 9 months after the first one. Systemic treatments after the second surgery were linked to an improved PFS. Conclusion: Younger age, Karnofsky index, MGMT methylation status and a median time between surgeries ≥9 months may be criteria for eligibility for surgery at recurrence.

The Glioma-IRE project - Molecular profiling in patients with glioma: steps toward an individualized diagnostic and therapeutic approach.

BACKGROUND: This study aimed to characterize the genetic profile of patients with glioma and discuss the impact of next-generation sequencing in glioma diagnosis and treatment. METHODS: Between 2019 and 2022, we analyzed the genetic profile of 99 patients with glioma through the Oncomine Focus Assay. The assay enables the detection of mutations in 52 driver genes, including single nucleotide variants (SNVs), copy number variants (CNVs), and gene fusions. We also collected and analyzed patients' clinic characteristics and treatment outcomes. RESULTS: Over a period of 35 months, 700 patients with glioma followed by our neuro-oncology unit were screened, and 99 were enrolled in the study; most of the patients were excluded for inadequate non-morphological MRI or lack/inadequacy of the tissue samples. Based on our findings, most patients with glioma present mutations, such as SNVs, CNVs or gene fusions. Our data were similar to those reported by The Cancer Genome Atlas Program in terms of frequency of SNVs and CNVs, while we observed more cases of gene fusions. Median overall survival, progression-free survival, and time to progression were significantly lower for patients with grade VI glioblastoma than those with other gliomas. Only four patients were offered a targeted treatment based on the mutation detected; however, only one received treatment, the others could not receive the selected treatment because of worsening clinical status. CONCLUSION: Routine timely molecular profiling in patients with glioma should be implemented to offer patients an individualized diagnostic approach and provide them with advanced targeted therapy options if available.

Pattern of care of brain tumor patients in the last months of life: analysis of a cohort of 3045 patients in the last 10 years.

BACKGROUND: End-of-life in patients with brain cancer presents special challenges, and palliative care approach is underutilized. Patients with brain cancer, in the last months of life, receive frequent hospital readmissions, highlighting bad end-of-life care quality. Early integration of palliative care improves quality of care in advanced stage of disease and patient's quality of death. PURPOSE: We retrospectively analyzed a consecutive series of patients with brain cancer discharged after diagnosis to evaluate pattern of treatment and rate of hospital readmission in the last months of life. DESIGN: Data were collected from the Lazio Region Healthcare database. SETTING: Adult patients discharged with diagnosis ICD-9 191.* between January 1, 2010, and December 31, 2019 were included. RESULTS: A total of 6672 patients were identified, and 3045 deaths were included. In the last 30 days 33% were readmitted to the hospital and 24.2% to the emergency room. 11.7% were treated with chemotherapy and 6% with radiotherapy. Most indicators of end-of-life care showed wide variability by hospital of discharge. CONCLUSIONS: Strategies to improve quality of care at the end of life and to decrease re-hospitalization and futile treatments are becoming increasingly important to improve quality of death and reduce healthcare costs. Variability observed by hospital of discharge indicates the lack of a standard approach to end-of-life care.

Malignant meningioma mTOR mutated and precision medicine.

BACKGROUND: WHO grade II and III meningiomas are more invasive than grade I malignancies and determine patients' shorter overall survival. Their tendency to recur after treatment has represented an important therapeutic challenge because of the limited treatment strategies at recurrence. Angiogenesis and mechanistic target of rapamycin (mTOR) activation are two of the main features of higher grade meningiomas, determining invasiveness and tendency to relapse. While these options prove promising, available clinical data on mTOR inhibitors' efficacy are somewhat limited. CASE STUDY: We report a case of a 25-year-old female patient diagnosed with a right parasagittal occipital anaplastic meningioma (grade III WHO) in 2013. The patient underwent multiple treatments and, in 2019, a further recurrence occurred. The patient reported an mTOR mutation, and it is for this reason that the MTB approved treatment with everolimus and bevacizumab. Therapy was administered in May 2019, and partial response and prolonged disease control was obtained in November 2021, when progression took place. The patient's death occurred in March 2022. CONCLUSIONS: This case report provides evidence on the efficacy of mTOR inhibitors as a treatment option in recurrent meningiomas. Furthermore, it highlights the importance of performing a molecular analysis as a preliminary step towards targeting the mTOR pathway.

Multidomain and long-term cognitive evaluation in malignant glioma patients.

Aim: We performed longitudinal evaluations of the neurocognitive status in glioma patients to describe possible variations over the course of illness. Materials and methods: Glioma patients underwent a complete battery of standardized neuropsychological tests pre-radiotherapy at 6, 12 and 24 months. Results: We enrolled 130 patients, 67.7% of whom had a deficit in at least one cognitive domain. The most affected domains included executive function (n = 68, 52.3%), long-term memory (n = 46, 35.3%) and short-term memory (n = 39, 30%). At follow-up, cognitive status worsened in 31.5%, remained unchanged in 38.4% and improved in 30.1% of patients. Conclusion: This is one of few studies investigating longitudinal neurocognitive status in a wide sample of patients to monitor neuropsychological changes due to tumor progression and treatment administration.

Malignant gliomas are brain tumors with dismal prognosis that can affect patients' neurocognitive status. We performed longitudinal neuropsychological assessments to describe variations due to illness progression and treatment administration. Patients underwent a battery of standardized neuropsychological tests tapping into different cognitive domains (memory, attention, abstract reasoning, executive functions, learning), pre-radiotherapy and at 6, 12 and 24 month follow-up. We enrolled 130 patients, and almost 70% of them had at least one cognitive deficit. The most affected domains were executive function and long- and short-term memory. At follow-up assessments, cognitive status worsened in one-third of patients, whereas it remained unchanged or improved in two-thirds of patients. This is one of few longitudinal studies investigating cognitive function in a large sample of patients to monitor changes along the illness course.

Recurrent glioblastoma: which treatment? A real-world study from the Neuro-oncology Unit "Regina Elena" National Cancer Institute.

BACKGROUND: The majority of patients with glioblastoma (GBM) experience disease progression. At recurrence, treatment options have limited efficacy. Many studies report a limited and short duration response rate. Although clinical trials represent the "gold standard" for providing evidence on efficacy of specific treatment strategies, real-world data can be considered more representative of the "real" GBM population. OBJECTIVE: To describe the management of GBM recurrence in a large real-world sample. METHODS: We analysed retrospectively the data stored in the database of the Neuro-oncology Unit, IRCCS "Regina Elena" National Cancer Institute, Rome, Italy. We considered only data of patients with histological diagnosis of GBM and disease recurrence during their follow-up. We excluded patients who did not receive treatment after the diagnosis. RESULTS: We analysed 422 patients (64% males, 36% females) with a mean age of 59.6 (range 16-87) years. At GBM recurrence, 135 (32.0%) patients underwent palliative care, and 287 (68.0%) underwent other treatments. Patients on palliative care were older, had a worse performance status, and a shorter time between GBM diagnosis and its recurrence. Patients who received chemotherapy in combination with other treatments (surgery and/or radiation therapy) at GBM recurrence had a longer survival than those in palliative care (p < 0.001). Surgery or radiation therapy alone did not have any effect on survival as compared with palliative care (p < 0.001). CONCLUSION: This study confirms the importance of a multidisciplinary approach even at GBM recurrence, suggesting that combination treatments play a key role in management of disease.

Neural underpinnings of the slowness of information processing in patients with traumatic brain injury: insights from tract-based spatial statistics.

Slowness of information processing (SIP) is frequently reported after traumatic brain injury (TBI). Previous studies point toward a pivotal role of white matter damage on speed of information processing. However, little is known about the more comprehensive and ecological assessment of SIP in TBI. Here, we combined an ecological assessment of SIP with the use of tract-based spatial statistics (TBSS) on individuals' fractional anisotropy (FA) maps. Twenty-six moderate-to-severe patients with TBI (21 males and 5 females) participated in this study: 10 individuals were classified as not having SIP (SIP-) and 16 were classified as having SIP (SIP +). SIP + showed lower FA in bilateral anterior thalamic radiation, corticospinal tract, cingulum, and forceps, as well as in bilateral inferior fronto-occipital, inferior and superior longitudinal fasciculi and uncinate fasciculus. Overall, this result is consistent with and expands previous reports on information processing speed to a more comprehensive and ecological perspective on SIP in TBI.

COV-BT Ire study: safety and efficacy of the BNT162b2 mRNA COVID-19 vaccine in patients with brain tumors.

BACKGROUND: The BNT162b2 vaccine conferred 95% protection against COVID-19 in people aged 16 years or older. OBJECTIVE: The aim of this observational study was to evaluate safety and efficacy of vaccine in patients affected by primary brain tumor (PBT). METHODS: We proposed COVID-19 vaccine to all patients affected by PBT followed by Neuroncology Unit of National Cancer Institute Regina Elena. RESULTS: 102 patients received the first dose, 100 the second, and 73 patients received the booster dose. After first dose, we observed one patient with fever and severe fatigue, while after the second one, we recorded adverse events in ten patients. No correlation was observed between adverse events and comorbidities. CONCLUSIONS: The COVID-19 vaccine is safe and well tolerated in PBT patients.

Eribulin in brain metastases of breast cancer: outcomes of the EBRAIM prospective observational trial.

Background: Eribulin shows some activity in controlling brain metastasis in breast cancer. Methods: This observational, multicenter study evaluated brain disease control rates, survival and safety in patients with brain metastatic breast cancer treated with eribulin in clinical practice. Results: A total of 34 patients were enrolled (mean age 49 years, 91% with visceral metastases) and 29 were evaluable for brain disease. Fourteen achieved disease control and showed a longer time without progression: 10 months (95% CI: 2.3-17.7) versus 4 months (95% CI: 3.3-4.7) in the control group (p = 0.029). Patients with clinical benefits at 6 months had longer survival. Leukopenia and neutropenia were the most frequent grade 3-4 toxicities. Conclusion: Eribulin confirms its effectiveness in patients with brain metastatic breast cancer. Further studies on larger cohorts are needed to confirm the results.

Phase II study of weekly carboplatin in pretreated adult malignant gliomas.

PURPOSE: Patients with relapse of recurrent glioma have a poor outcome and limited treatment options. The aim of this study is to investigate the clinical benefit and tolerability of weekly intravenous administration of carboplatin-based monotherapy in adult glioma patients who had progressed from previous chemotherapy lines based on temozolomide and nitrosoureas. METHODS: This was a single-arm, phase II study. Eligibility criteria included progressive or recurrent glioma after radiotherapy and chemotherapy-based treatments and Karnofsky performance status (KPS) > 60. RESULTS: Thirty-two patients (median age 43.5 years) were enrolled to receive weekly carboplatin monotherapy in an intravenous method of administration. The median duration of response was 7.3 months with an overall disease control rate of 31.3%. Median progression-free survival was 2.3 months while overall survival was 5.5 months. Pre-treatment with corticosteroids (i.e. dexamethasone) was associated to clinical benefit in 43.8% of patients. Patients achieving clinical benefit exhibited a longer progression-free survival (4.6 vs. 1.5 months; p > 0.001) and overall survival (7.9 vs. 3.2 months; p = 0.041) compared with those not achieving clinical benefit. CONCLUSIONS: Our findings show that single agent, weekly, intravenous administration of carboplatin may have a role in patients with recurrent glioma and suggest that pre-treatment with corticosteroids may confer survival benefit.

Comorbidities in elderly patients with glioblastoma: a field-practice study.

AIM: This single-center study evaluated the effect of comorbidities on progression-free and overall survival in elderly patients with glioblastoma multiforme (GBM). PATIENTS & METHODS: Comorbid conditions were identified in each patient with the modified version of the cumulative illness rating scale (CIRS). RESULTS:  Total of 118 patients with GBM were enrolled. An age of >75 years at diagnosis, high CIRS, comorbidity index and performance status play a predictive role on survival. CONCLUSION: Comorbidities play an important prognostic role in elderly patients with GBM, a factor too often neglected in clinical practice. If the prognostic role of comorbidity measured by CIRS on outcome will be confirmed, it would be interesting to add it in the algorithm for treatment choice in elderly GBM patients.

A multicenter real-world study of bevacizumab in heavily pretreated malignant gliomas: clinical benefit is a plausible end point?

Aim: This multicenter, retrospective study evaluates the clinical benefit (CB) of bevacizumab, alone or in combination, in recurrent gliomas (RG). Patients & methods: The CB was measured as a reduction of corticosteroid dosage and an improvement ≥20 points in the Karnofsky Performance Status lasting ≥3 months. Results: We collected data of 197 RG patients. A CB was observed in 120, patients without significant differences between patients treated with bevacizumab alone or in combination. The rate of patients who achieved a CB and free from progression at 1 year was 21.5 versus 1.4% in patients who did not report CB. Conclusion: The majority of RG patients treated with bevacizumab reported CB. Moreover, patients with CB showed improved survival.

Neurological adverse events of mitotane in adrenocortical carcinoma: results of a pilot study.

Introduction: Mitotane, the only drug approved by the Food and Drug Administration (FDA) for the treatment of adrenocortical carcinoma, is associated with several side effects including neurotoxicity. The aim of our study is to investigate the relationship between mitotane plasma levels and neurological toxicity. Methods: We have considered five patients affected by adrenocortical carcinoma treated with mitotane. The neurological assessment included a neurological examination, an electroencephalogram, event-related potentials (P300), and a neuropsychological assessment. All of the patients were first considered at the onset of symptoms of neurotoxicity or when mitotanemia levels were above 18 mg/L, for the second time at mitotanemia normalization and subsequently at its further increase, or in case of persistent neurological abnormalities, some months after normalization. Results: At the first neurotoxicity, four patients showed impaired neurological examination, electroencephalogram, and P300; three patients had impaired neuropsychological assessment; one patient, only P300. At mitotanemia normalization, the neurological examination became normal in all patients and electroencephalogram normalized in one patient, improved in another one, continuing to be altered in the other three. P300 latency and neuropsychological assessment normalized in two patients and persisted altered in the patient experiencing long-term mitotane toxicity. At the third evaluation, in the patient with prolonged mitotane toxicity, the normal mitotanemia in the previous 9 months restored P300 and improved the electroencephalogram but not the neuropsychological assessment. In the two patients experiencing a further rise of mitotanemia, neurological examination was normal but P300 and electroencephalogram were altered. Conclusion: The results of our study highlighted the presence of neurophysiological and neuropsychological abnormalities associated with mitotane values above 18 mg/L.

Assessing topographical orientation skills in cannabis users.

The long-term effects of cannabis on human cognition are still unclear, but, considering that cannabis is a widely used substance and, overall, its potential use in therapeutic interventions, it is important to evaluate them. We hypothesize that the discrepancies among studies could be attributed to the specific cognitive function investigated and that skills subserved by the hippocampus, such as the spatial orientation abilities and, specifically, the ability to form and use cognitive maps, should be more compromised than others. Indeed it has been showed that cannabis users have a reduced hippocampus and that the hippocampus is the brain region in which cannabis has the greatest effect since it contains the highest concentration of cannabinoid receptors. To test this hypothesis we asked 15 heavy cannabis users and 19 nonusers to perform a virtual navigational test, the CMT, that assesses the ability to form and use cognitive maps. We found that using cannabis has no effect on these hippocampus-dependent orientation skills. We discuss the implications of our findings and how they relate to evidence reported in the literature that the intervention of functional reorganization mechanisms in cannabis user allows them to cope with the cognitive demands of navigational tasks.

Prognostication in brain tumors.

Despite the use of aggressive multimodality therapies, the prognosis of brain tumor patients remains poor. Tumors of glial origin typically have the worst prognosis, with a predicted median survival of 12-15months for glioblastoma multiforme (WHO grade IV) and 2-5years for anaplastic glioma (WHO grade III). Palliative care problems and needs in patients with primary and secondary brain tumors are significantly different, both due to different trajectory of disease and to variable prognosis which in metastatic brain tumors is related to the natural history of primary tumors. This chapter describes the complex interactions influencing communication and the treatment decision process in primary brain tumor patients. The whole trajectory of disease and particularly the end-of-life (EOL) phase of brain tumor (BT) patients are quite different in respect to the expected trajectory observed in the general cancer population. The need to improve the communication of prognosis in BT patients has been clearly reported in neuro-oncological literature, but several issues may hinder a good communication in these patients. Adequate prognostic awareness (PA) is important for several reasons: to respect patient autonomy, to obtain her/his preferences about treatments and goal of care, and to share EOL treatment decisions. The high incidence of cognitive deficits in BT patients is one of the most challenging issues influencing the quality of communication and the participation of patients in the process of treatment decisions. Impaired neurocognitive functions may impact capacities of understanding, appreciation, reasoning, and expression of choice, reducing Medical Decisions Capacity (MDC). The lack of capacity to express preferences about EOL treatment decisions represents an important ethical issue, with a great impact on both the patient's family and healthcare professionals involved in the decision processes. Also, patients' coping styles may have an important influence in critical aspects of care such as communication of diagnosis and prognosis, discussion with patients and their caregivers about goal of treatments, early introduction of PC, and advanced planning of patients' preferences concerning EOL treatment and issues. Several barriers hinder good communication in BT patients. This chapter analyzes emerging literature data and possible strategies to improve communication about prognosis and goals of care and to promote patients' involvement in the treatment decision process particularly in the palliative care setting.

Two Ecological Tools for Testing Slowness of Information Processing in Italian Patients with Moderate-to-Severe Traumatic Brain Injury.

Slowness of Information Processing (SIP) is frequently experienced after traumatic brain injury (TBI); however, the impact of SIP on everyday functioning may be underestimated by standard neuropsychological tests. OBJECTIVE: we aimed to adapt two ecological instruments assessing SIP in Italian patients with moderate-to-severe TBI, as formerly proposed by Winkens and colleagues for persons with stroke, testing also its possible relation with other neuropsychological processes and functional outcomes. METHOD: we performed an observational study on 37 patients with moderate-to-severe TBI and 35 demographically matched healthy controls, who underwent the Mental Slowness Observation Test (MSOT) and the Mental Slowness Questionnaire (MSQ), which had been adapted through a pilot study on independent sample of participants; extensive neuropsychological and functional evaluations were performed as well. RESULTS: We found good clinical and psychometric properties of the Italian adaptation of the MSOT and MSQ; also, performance on MSOT significantly correlated with executive functions. Moreover, patients with TBI are significantly slower and less accurate than healthy controls on the MSOT, in particular in tasks with time limits. Even if the subjective feeling of SIP does not differ between patients and controls, we found a significant correlation between MSQ and MSOT. Finally, the performances on the MSOT correlated with measures of functional outcome and community integration. CONCLUSIONS: the results support the use of the MSOT and the MSQ to measure SIP in an ecological fashion in patients with TBI, so that specific treatments for persons with acquired brain injury can be prescribed.

Italian adaptation of the Uniform Data Set Neuropsychological Test Battery (I-UDSNB 1.0): development and normative data.

BACKGROUND: Neuropsychological testing plays a cardinal role in the diagnosis and monitoring of Alzheimer's disease. A major concern is represented by the heterogeneity of the neuropsychological batteries currently adopted in memory clinics and healthcare centers. The current study aimed to solve this issue. METHODS: Following the initiative of the University of Washington's National Alzheimer's Coordinating Center (NACC), we presented the Italian adaptation of the Neuropsychological Test Battery of the Uniform Data Set (I-UDSNB). We collected data from 433 healthy Italian individuals and employed regression models to evaluate the impact of demographic variables on the performance, deriving the reference norms. RESULTS: Higher education and lower age were associated with a better performance in the majority of tests, while sex affected only fluency tests and Digit Span Forward. CONCLUSIONS: The I-UDSNB offers a valuable and harmonized tool for neuropsychological testing in Italy, to be used in clinical and research settings.

Coping Style in Glioma Patients and Their Caregiver: Evaluation During Disease Trajectory.

Background: Patients with glioma have a poor prognosis and, in a short period of time, have to deal with severe forms of disability, which compromise their psychological distress and quality of life. The caregivers of these patients consequently carry a heavy burden in terms of emotional and patient care. The study aims to evaluate the coping strategies of patients and their caregivers during the course of the disease in order to frame the adaptation process in a rapidly progressing pathology. Methods: A prospective study on 24 dyads of patients affected by malignant glioma and their caregivers was conducted between May 2016 and July 2018. Questionnaires designed to identify the coping style (MINI-MaC Scale) and psychological distress (HADS scores) and assess QOL (EQ-5D) were administered at two time points: at first lines of treatment and at disease recurrence. Results: Patients and their caregiver structure adaptive coping strategies during the disease: a coping style oriented toward a fighting spirit prevails at baseline (Mini-Mac Mean 3.23); fatalism prevails at recurrence (Mini-Mac Mean 3.03). Psychological distress affects the coping style expressed: high levels of anxiety symptoms were found to be significantly associated with a coping style oriented toward anxious preoccupation, helpless-hopeless, and fatalism; low depressive symptoms were inversely correlated with fighting spirit coping style. Patients' and caregivers' perceptions of quality of life were correlated between them and with performance status assessed by clinicians. In a dyadic perspective, the adaptation of a member of the couple varies as a function of the other partner's coping style. Conclusions: Our data are in line with previous literature on cancer patients, demonstrating that coping style is not a persistent dimension of personality, but can change depending on the situation. Despite the disease rapid course, patients and their caregivers can structure adaptive and functional defenses to manage the disease.

Neutrophil-to-lymphocyte ratio, Factor VIII and Antithrombin III: inflammatory-clotting biomarkers in glioma.

One of the key difficulties in glioma treatment is our limited ability to consistently assess cancer response or progression either by neuroimaging or specific blood biomarkers. An ideal biomarker could be measured through non-invasive methods such as blood-based biomarkers, aiding both early diagnosis and monitoring disease evolution. This is a single-center, case-control, 10-year retrospective, longitudinal study. We evaluated routine coagulation factors in 138 glioma patients (45 Females/93 Males; median [range] age, 56.4 [27-82] years; 64 non-recurrent/74 recurrent) and, for comparison, in 56 relapsing-remitting MS patients (41 Females/15 Males; 40.8 [25-62] years, 35 stable/21 active) and 23 controls (16 Females/7 Males; 41.7 [24-62] years) as well as Neutrophil-to-lymphocyte ratio (NLR) in subgroups of 127 glioma patients, 33 MS patients and 23 healthy controls. Secondly, we assessed whether these indicators could be predictive of overall (OS) and progression-free survival (PFS) in glioma patients. NLR, d-dimer, Antithrombin III and Factor VIII were significantly higher in glioma patients compared to both MS patients and controls (p<0.0001 for all). ROC curves confirmed that either NLR, Antithrombin III or Factor VIII were moderately accurate biomarkers (0.7
