Assessment of surgery-related morbidity in patients with diffuse gliomas
Sagberg, Lisa Millgård (Doctoral theses at NTNU;2018:327, Doctoral thesis, 2018)The work presented in this thesis focuses on assessment of surgery-related morbidity in patients with diffuse gliomas – the most common primary malignant brain tumour in adults. Diffuse gliomas can be subdivided into ... -
Brain atlas for assessing the impact of tumor location on perioperative quality of life in patients with high-grade glioma: A prospective population-based cohort study
Sagberg, Lisa Millgård; Iversen, Daniel Høyer; Fyllingen, Even Hovig; Jakola, Asgeir Store; Reinertsen, Ingerid; Solheim, Ole (Journal article; Peer reviewed, 2019)Background Tumor location is important for surgical decision making. Particular attention is paid to regions that contain sensorimotor and language functions, but it is unknown if these are the most important regions from ... -
Brain infarctions after glioma surgery: prevalence, radiological characteristics and risk factors
Strand, Per Sveino; Berntsen, Erik Magnus; Fyllingen, Even Hovig; Sagberg, Lisa Millgård; Reinertsen, Ingerid; Gulati, Sasha; Bouget, David; Solheim, Ole (Peer reviewed; Journal article, 2021)Background: Prevalence, radiological characteristics, and risk factors for peritumoral infarctions after glioma surgery are not much studied. In this study, we assessed shape, volume, and prevalence of peritumoral infarctions ... -
Clinical Course in Chronic Subdural Hematoma Patients Aged 18–49 Compared to Patients 50 Years and Above: A Multicenter Study and Meta-Analysis
Bartek, Jiri; Sjåvik, Kristin; Dhawan, Sanjay; Sagberg, Lisa Millgård; Kristiansson, Helena; Ståhl, Fredrik; Förander, Petter; Chen, Clark C.; Jakola, Asgeir Store (Journal article; Peer reviewed, 2019)Objective: Chronic Subdural Hematoma (cSDH) is primarily a disease of elderly, and is rare in patients <50 years, and this may in part be related to the increased brain atrophy from 50 years of age. This fact may also ... -
Does preoperative health-related quality of life predict survival in high-grade glioma patients? – a prospective study
Haraldseide, Lisa Marie; Jakola, Asgeir S; Solheim, Ole; Sagberg, Lisa Millgård (Peer reviewed; Journal article, 2019)Purpose: To explore if preoperative patient-reported health-related quality of life (HRQoL) provides additional prognostic value as a supplement to other preoperatively known clinical factors in patients with high-grade ... -
How well do neurosurgeons predict survival in patients with high-grade glioma?
Sagberg, Lisa Millgård; Jakola, Asgeir S.; Reinertsen, Ingerid; Solheim, Ole (Journal article; Peer reviewed, 2021)Due to the lack of reliable prognostic tools, prognostication and surgical decisions largely rely on the neurosurgeons’ clinical prediction skills. The aim of this study was to assess the accuracy of neurosurgeons’ prediction ... -
Impact of transsphenoidal surgery for pituitary adenomas on overall health-related quality of life: a longitudinal cohort study
Sommerfelt, Hanne; Sagberg, Lisa Millgård; Solheim, Ole (Peer reviewed; Journal article, 2019)Background: Previous studies show a moderate improvement in health-related quality of life (HRQoL) following transsphenoidal surgery for pituitary adenomas, but no consistent predictors of HRQoL outcome have been identified. ... -
Perioperative fatigue in patients with diffuse glioma
Schei, Stine; Solheim, Ole; Jakola, Asgeir S; Sagberg, Lisa Millgård (Peer reviewed; Journal article, 2020)Purpose Few studies have assessed fatigue in relation to glioma surgery.
