Gamma Knife Radiosurgery does not alter the copy number aberration profile in sporadic vestibular schwannoma
Håvik, Aril Løge; Bruland, Ove; Dhayalan, Dhanushan; Lund-Johansen, Morten; Knappskog, Per (Journal article; Peer reviewed, 2020)Introduction: Ionizing radiation is a known etiologic factor in tumorigenesis and its role in inducing malignancy in the treatment of vestibular schwannoma has been debated. The purpose of this study was to identify a copy ... -
Genetic alterations associated with malignant transformation of sporadic vestibular schwannoma
Håvik, Aril Løge; Bruland, Ove; Miletic, Hrvoje; Poulsgaard, Lars; Scheie, David; Fugleholm, Kåre; Lund-Johansen, Morten; Knappskog, Per Morten (Journal article; Peer reviewed, 2022)Introduction: Malignant peripheral nerve sheath tumor of the vestibulocochlear nerve (VN-MPNST) is exceedingly rare and carries a poor prognosis. Little is known about its underlying genetics and in particular the process ... -
Genetics of vestibular schwannoma : Genetic landscape of irradiated and radiation-naïve benign and malignant vestibular schwannoma
Håvik, Aril Løge (Doctoral thesis, 2022-05-06)Background: Vestibular schwannoma (VS) is a benign intracranial neoplasm associated with reduced quality of life. Malignant peripheral nerve sheath tumor of the vestibular nerve (VN-MPNST) is the malignant counterpart, an ... -
Is intracranial volume a risk factor for IDH-mutant low-grade glioma? A case-control study
Sagberg, Lisa Millgård; Fyllingen, Even Hovig; Hansen, Tor Ivar; Strand, Per Sveino; Håvik, Aril Løge; Sundstrøm, Terje; Corell, Alba; Jakola, Asgeir Store; Salvesen, Øyvind; Solheim, Ole (Journal article; Peer reviewed, 2022)Purpose Risk of cancer has been associated with body or organ size in several studies. We sought to investigate the relationship between intracranial volume (ICV) (as a proxy for lifetime maximum brain size) and risk of ... -
The SH3PXD2A-HTRA1 fusion transcript is extremely rare in Norwegian sporadic vestibular schwannoma patients
Taule-Sivertsen, Peter; Bruland, Ove; Håvik, Aril Løge; Bratland, Eirik; Lund-Johansen, Morten; Knappskog, Per Morten (Journal article; Peer reviewed, 2021)Introduction Vestibular schwannoma (VS) is a benign intracranial tumor in which the underlying genetics is largely uncertain, apart from mutations in the tumor suppressor gene NF2. Alternative tumorigenic mechanisms have ...
