Identification of patients suffering from elevated psychosocial distress, the sources of the distress, and the necessary treatment of the distress can be rather difficult within the neurosurgical setting (e.g., lack of time, cognitive or aphasic disorders of the patients). The distress thermometer (DT) is a single-item rapid distress screening tool by use of which these difficulties can be minimized. The objective of this study was to determine the optimum DT cut-off score that would identify significant distress in patients with intracranial tumours thus validating its use in the neurosurgical setting. In all, 150 patients were tested either during in-patient stay or during a follow-up examination before and after the neurosurgical removal of a primary intracranial neoplasm. Patients were administered the DT with the hospital anxiety and depression scale (HADS), the gold standard against which the DT was compared. The area under the receiver operating characteristics curve (ROC) was ≥0.82. Thus, the ability of the DT to correctly identify patients as significantly distressed was excellent. The DT ranges from 0 to 10. Its optimum cut-off score for identifying distressed patients was at or above 6 (sensitivity ≥ 88%; specificity ≥ 53%). The DT is a valid and practicable screening instrument for assessment of levels and sources of distress in patients with intracranial tumours in the neurosurgical setting.

Objective: Patients with intracranial tumours often suffer from clinically relevant psychological distress. However, levels of distress and contributing factors have not been systematically evaluated for the early course of the disease. Using the National Comprehensive Cancer Network's Distress Thermometer (DT), we evaluated the extent and sources of distress within a population of patients with intracranial neoplasms.Methods: One hundred and fifty-nine patients were included who underwent craniotomy for newly diagnosed intracranial tumours at our department. All patients completed the DT questionnaire, a single-item 11-point visual analogue scale measuring psychological distress. The appendant problem list (PL) consists of 40 items representing problems commonly experienced by cancer patients. Patients were asked to mark any experienced sources of distress.Results: Percentage of patients suffering from relevant distress was 48.4% (cut-off X6). DT-scores were significantly associated with depression and anxiety as well as reported number of concerns. On average, patients reported 6.9 sources of cancer-related distress. Objective medical data (e.g. tumour stage) as well as sociodemographic data (e.g. gender, IQ) were not associated with psychological distress at this early phase.Conclusions: Prevalence of elevated distress is high shortly after primary neurosurgical treatment in patients with intracranial tumours and cannot be predicted by objective data. As a consequence, sources of distress can and should be routinely assessed and targeted in these individuals in this particular period. Further studies are needed to help to identify patients who are at risk of suffering from long-term emotional distress in order to enable targeted psychosocial intervention.

Although the combination of awake craniotomy and intraoperative MRI is demanding, it was both tolerable and reasonable for the patients. Our data confirm that intraoperative MRI appears to have no additional significant impact on the subjective patient perception, although it does prolong the procedure.
