Om mig

  • I am a physicist from Italy, specialized in Medical Physics. I moved to
    Sweden in 1988.
    I am associate professor at Stockholm University since 2008, where I also got
    my PhD in 1998 (Thesis title: Modelling heart and lung complication data in
    radiation therapy of the breast).
    Since 2010 I am employed as Head of the Section of Radiotherapy Physics and
    Engineering at Karolinska University Hospital. The section is part of the
    Medical Radiation Physics and Nuclear Medicine Unit. The group comprises
    about 40 people
  • they are medical physicists and engineers providing medical
    radiation physics and Hardware/Software competence to the Radiotherapy
    Medical Unit and to the Gammaknife department at Karolinska University
    Hospital, to the Skandion proton center in Uppsala and to St Erik
    Ophthalmologic Hospital (St Erik Ögon Sjukhus) in Stockholm.
    My position as Head of department started in 2010. Earlier I was employed for
    several years as Medical Physicist at Karolinska Hospital.
    My tasks as head of department focus on management of clinic, research and
    education within the discipline. This includes identification of research-
    and development goals relevant to the clinical activity, and in alignment
    with the research and development goals of Karolinska University Hospital and
    of Karolinska Insititute
    · My scientific production has led to 42 articles in
    peer-reviewed journals, three reports for SSM (Swedish Radiation Safety
    Authority), one report for the European Union, 1 book chapter.
    By August 2022 I had 5826 citations and an h-index of 28 (Scopus).
    · I am currently co-supervisor of two KI PhD students, a
    medical oncologist and a medical physicist, respectively. I have been
    co-supervisor of 1 PhD student at KI, supervised 5 MSc students at Stockholm
    University and 1 Speciality Student in Medical Physics at Milano University.
    I am member of the radiotherapy R&
  • D group at Karolinska/KI
    I am member of the Swedish Society of Radiation Oncology since 2021
    I am member of the ESTRO Physics Leadership group since 2021
    · I have acted as opponent of 2 PhD theses, in the
    Netherlands and in Denmark, respectively, and been part of the examination
    Committee of 4 PhD theses.
    · I have been a member of the Scientific Council on ionizing
    radiation within Oncology for the Swedish Radiation Safety Agency (2010-2012)
    · I have been a member of the ESTRO board - European SocieTy
    for Radiotherapy and Oncology (2003-2006)
    · I lecture at graduate and post-graduate courses within
    curricula for medical physicists, radiation therapists and oncologists at
    international academic sites. I have been part of the Faculty of the ESTRO
    course on Advanced Radiotherapy Modalities and of the Royal Marsden course in
    Medical Physics. I have been invited lecturer up to now in 20 national and
    European conferences, and at 25 national and international courses.
    · I have been the organizer of several European courses and
    have been the scientific chair, i.e- chair of the scientific program
    committee, for two ESTRO conferences (European SocieTy for Radiotherapy and
    Oncology) in 2003 and 2006 respectively.
    *In my affiliation to KI, I am committed to*
    1.Strengthening the research profile of radiation therapy within KI, in line
    with the Cancer Comprehensive Center strategy plan
    2.Facilitating the integration and implementation of basic research and
    development of radiation therapy in the clinic, with special focus to Medical
    Radiation Physics
    3. Reinforcing the dialogue and the interaction between clinic, education and
    research from the Medical Physics Science perspective


  • *Modelling of radiation therapy side effects*
    I have been involved in several projects within modelling of radiotherapy
    side effects, a field where I have actively worked since the early period of
    modern 3D conformal therapy.
    Cardiac and lung complication after radiation therapy of the breast have been
    the core of my studies, which have followed the changes and the implications
    for the field introduced by the technologic evolution in radiation therapy
    during almost three decades. The research has contributed to the
    identification of constraints, i.e. numbers which drive the optimization of
    treatment plans for heart and lung to be used in the clinical practice. The
    analyses have been performed initially in terms of literature studies and
    later on large patient groups, which was necessary for the modelling of such
    severe and late complications. The studies have been performed in
    collaborations, one of them was the EU project RACE, together with UK,
    Denmark and Italy. I have also been involved in several studies modelling
    lung complications after Stereotactic Body RadioTherapy (SBRT) and actively
    worked on the modelling of normal tissue complications following prostate
    radiotherapy in collaboration with Italian centers.
    I am currently part of a study which investigates the normal tissue
    complication following Head and Neck radiation therapy, based on real life
    data collected from a large cohort of patients. Predictive models of
    Xerostomia, identification of organs at risk for swallowing dysfunction,
    re-irradiations issues are the main goals of the research project which is
    entirely conducted within Karolinska University Hospital and KI (dr Eva
    Onjukka is the project PI).
    Over the years I have organized the scientific program of several courses on
    normal tissue complication modeling issues and have lectured on this subject,
    mostly in international conferences and courses.
    *Radiotherapy in the treatment of Oesophageal cancer*
    Radiotherapy plays a major role in oesophagus cancer treatment, either with
    curative or palliative intent. A collaboration with Clintec on this subject
    has started, where high definition radiotherapy data for different studies
    and analyses are provided.
    In particular a randomized international multicenter study, the NEEDS trial
    (/NEoadjuvant chemoradiotherapy for Esophageal squamous cell carcinoma versus
    Definitive chemoradiotherapy with salvage Surgery as needed/), has recently
    started under the lead of prof Magnus Nilsson, Clintec. In this study
    curative chemoradiotherapy with selective surgery when needed for local
    tumour control will be compared to nCRT and planned surgery for all. The
    participation in the study of several centers from all over the world
    requires a robust Quality Assurance program for Radiation Therapy (QA RT) in
    order to ensure that the participating centers deliver the prescribed
    radiation doses in compliance with the clinical protocol. The QA RT program
    has been set up and is run by the Medical Physics group in collaboration with
    the Radiation Therapy medical unit.
    *Imaging and motion management in high-precision radiotherapy*
    During the last two decades there has been increased use of high-precision
    radiotherapy by SBRT for the treatment of small tumours in lung and liver
    with ablative dose of about 7-20 Gy per fraction, compared to the
    conventional daily fraction of 2 Gy. The approach shift differs also when it
    comes to the radiobiological effect. When treating central lung tumours,
    serious side effects, such as bronchopulmonay haemorrage, can occur and have
    to be taken into account in treatment planning. The tumour movements, e.g.
    due to breathing, need to be characterized and incorporated into the
    treatment planning with procedures which limit as much as possible the
    irradiated normal tissue volume. In a PhD project on this subject, where I
    act as co-supervisor, the main addressed questions are the accumulated dose
    to bronchi in the treatment of central lung tumors
  • the development of a
    method to define individualized safety margins around the tumour, based on
    4D_CT image series
  • and the estimation of breathing-related tumor movements
    based on dynamic MR imaging.
    These studies are partly included in a PhD program, where I am co-supervisor.
