ABSTRACT

BACKGROUND: Patients affected by a high-grade glioma (HGG) have a poor prognosis with a median survival of 12-16 months. Such poor prognosis affects the perception of the remaining life by patients and the neuropsychological status can strongly affect every-day functioning of these patients. Monitoring changes of neuropsychological functioning (NPF) overtime may provide better clinical information and optimize the neuro-oncological management. The aims of our work were (1) to investigate the feasibility of a complex neuropsychological battery in HGG patients before and during follow-up after surgery; (2) to study the neuropsychological profile of patients affected by HGGs and their relation with the disease status (relapse/death) across time after surgery. METHODS: One hundred two patients who received surgery for HGG between 2011 and 2017 were studied. All clinical data were prospectively recorded. NPF was assessed during the neuro-oncological follow-up through the Milano-Bicocca Battery (MIBIB). Statistical analysis was performed on the neuropsychological results of the tests administered. RESULTS: First, MIBIB proved to be suitable for patients with HGG tumors before and after surgery, and during long-term follow-up; it also showed a cluster structure representative of the principal cognitive domains. Second, we found a steep decline in the neuropsychological profile before death and/or tumor relapse for the 52% of the neuropsychological tests administered. CONCLUSION: Complex neuropsychological batteries can be administered to HGG patients before and during follow-up after surgery. There is a correlation between neuropsychological deterioration and tumor relapse and/or death, which may reflect a progressive damage to cognitive functions due to tumor infiltration and progression.

ABSTRACT

High grade gliomas (HGG) are tumors with a rapidly progressive course and the standard of care consists of surgery and chemo-radiotherapy. Elderly patients with HGG usually have a worse prognosis due to their comorbidities and difficulties in accessing or completing adjuvant treatments. The purpose of our study was to assess the influence of pre-operative factors (MMSE, age, sex, KPS, tumor volume) on the post-operative access to chemo-radiotherapy in the elderly population. In addition, the influence of the access to adjuvant therapies on overall survival (OS) was assessed. We retrospectively reviewed our consecutive case series of 117 elderly patients (≥65 years) with HGG treated in our Institution. All the clinical records regarding age, sex, tumor location, MMSE, KPS, access to adjuvant treatments and OS were analyzed. 72 males and 45 females with a median age of 71 years were analyzed. Adjuvant therapies were considered; concomitant chemo-radiotherapy with standard radiotherapy or hypofractionated radiation regimen. 84 patients had access to adjuvant therapies. Access to therapies was associated with a median age of 71(range 66-80) years, a median MMSE of 26(range 5-30), and a median tumor volume of 24 cm3(range 1-140). The median OS was 13 months for patients who had access to adjuvant therapies and 5 months for patients who did not. In the elderly patients with HGG, the MMSE, age and tumor volume were predictive of post-surgery access to adjuvant treatments. OS was significantly longer in elderly patients with HGG who had access to post-surgery chemo-radiotherapy.

ABSTRACT

Mental time travel (MTT) abilities could be particularly compromised in schizophrenic patients due to a deficit of the cognitive processes at the basis of remembering the past and imaging the future: constructive processes, theory of mind and self-awareness. Accordingly, we assumed that the neural circuits typically associated with MTT in healthy people might be partially compromised in chronic schizophrenic patients. To quantitatively and anatomically test our hypothesis, we run two meta-analyses using the Activation Likelihood Estimate method: (i) a neurofunctional meta-analysis on MTT in healthy subjects, (ii) a morphometrical meta-analysis on chronic schizophrenia. The results of the two meta-analyses were overlapped in order to identify the candidate regions involved in MTT deficit in schizophrenia. A significant overlap was found in the vmPFC, in the precuneus, in the hippocampus and in the insular cortex. We assume that MTT deficits in schizophrenic patients may be the results of a complex dysfunctional interaction between the system underlying the creation of self-representation, the constructive system and the salience attribution network.
