Clinical experience of volumetric-modulated flattening filter free stereotactic body radiation therapy of lesions in the lung with deep inspiration breath-hold
Mørkeset, Siri Tessem; Lervåg, Christoffer; Lund, Jo-Åsmund; Jensen, Christer André (Peer reviewed; Journal article, 2022)This clinical study aimed to evaluate lung cancer patients’ ability to perform deep inspiration breath-hold (DIBH) during CT simulation and throughout the treatment course of stereotactic body radiation therapy (SBRT). In ... -
Continuous glucose monitoring as a tool in detection and treatment of hypoglycemia in patients with late dumping syndrome – a pilot project
Flatval, Håvard (Master thesis, 2022)Introduksjon: Fedme er en kronisk sykdom som disponerer for flere komorbiditeter. Roux-en- Y gastrisk bypass (RYGB) er en prosedyre som blir brukt i behandlingen av alvorlig overvekt, og gir vekttap til pasienten. Hypoglykemi ... -
Deep-inspiration breath-hold - Development and utilization of a deep-inspiration breath-hold system for breast cancer radiotherapy
Jensen, Christer André (Doctoral theses at NTNU;2018:315, Doctoral thesis, 2018)The purpose of this thesis was to develop a deep-inspiration breath-hold (DIBH) system and study the performance and clinical implications in the treatment of leftsided breast cancer and radiotherapy. This was investigated ... -
Development of a deep inspiration breath-hold system for radiotherapy utilizing a laser distance measurer
Jensen, Christer André; Skottner, Nils Eivind; Frengen, Jomar; Lund, Jo-Åsmund (Journal article; Peer reviewed, 2017)Deep inspiration breath‐hold (DIBH) is a technique for treating left‐sided breast cancer (LSBC). In modern radiotherapy, one of the main aims is to exclude the heart from the beam aperture with an individualized beam design ... -
Dose to penile bulb is not associated with erectile dysfunction 18 months post radiotherapy: A secondary analysis of a randomized trial
Tøndel, Hanne; Lund, Jo-Åsmund; Lydersen, Stian; Wanderås, Anne Dybdahl; Aksnessæther, Bjørg Yksnøy; Jensen, Christer André; Kaasa, Stein; Solberg, Arne (Journal article; Peer reviewed, 2018)Background Erectile dysfunction is a common side effect of prostate cancer (PC) therapy. In this randomized study (The RIC-study) we used patient reported outcomes to evaluate sexual function 18 months after combined ... -
Free breathing VMAT versus deep inspiration breath-hold 3D conformal radiation therapy for early stage left-sided breast cancer
Jensen, Christer André; Funderud, Marit; Lervåg, Christoffer (Peer reviewed; Journal article, 2021)The purpose of the in silico study was to compare free breathing volumetric modu-lated arc therapy (VMAT) to standard deep inspiration breathhold (DIBH) threedi-mensional conformal radiotherapy (3DCRT) and determine ... -
Monitoring deep inspiration breath hold for left-sided localized breast cancer radiotherapy with an in-house developed laser distance meter system
Jensen, Christer André; Abramova, Tatiana Mikhailovna; Frengen, Jomar; Lund, Jo-Åsmund (Journal article; Peer reviewed, 2017)Deep inspiration breath hold (DIBH) in left‐sided breast cancer radiotherapy is a technique to reduce cardiac and pulmonary doses while maintaining target coverage. This study aims at evaluating an in‐house developed DIBH ... -
Neonatal transitional support with intact umbilical cord in assisted vaginal deliveries: A quality-improvement cohort study
Sæther, Elisabeth; Reinhart-van Gülpen, Friedrich; Jensen, Christer André; Myklebust, Tor Åge; Eriksen, Beate Horsberg (Peer reviewed; Journal article, 2020)Background Deferring cord clamping has proven benefits for both term and preterm infants, and recent studies have demonstrated better cardio-respiratory stability if clamping is based on the infant’s physiology, and whether ... -
Radiotherapy for prostate cancer – Does daily image guidance with tighter margins improve patient reported outcomes compared to weekly orthogonal verified irradiation? Results from a randomized controlled trial
Tøndel, Hanne; Lund, Jo-Åsmund; Lydersen, Stian; Wanderås, Anne Dybdahl; Aksnessæther, Bjørg Yksnøy; Jensen, Christer André; Kaasa, Stein; Solberg, Arne (Journal article; Peer reviewed, 2018)Background Novel cancer drugs are subject to strict scientific evaluation of safety and efficacy and usually undergo a cost effectiveness analysis before approval for use in clinical practice. For new techniques in ... -
Rectal volume variations and estimated rectal dose during 8 weeks of image-guided radical 3D conformal external beam radiotherapy for prostate cancer
Tøndel, Hanne; Solberg, Arne; Lydersen, Stian; Jensen, Christer André; Kaasa, Stein; Lund, Jo-Åsmund (Journal article; Peer reviewed, 2019)The introduction of modern image-guided radiotherapy (IGRT) has given new insight regarding organ motion in radiotherapy (RT), both in general and in treatment for prostate cancer (PC) [1]. IGRT with daily Cone-beam computed ... -
