This retrospective study (2007–2014) included 118 Norwegian female patients. All ...
    • Continous controversy about radiation oncologists' choice of treatment regimens for bone metatases: should we blame doctors, canser-related features, or design of previous clinical studies 

      Nieder, Carsten; Pawinski, Adam; Dalhaug, Astrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Recent studies from Italy, Japan and Norway have confirmed previous reports, which found that a large variety of palliative radiotherapy regimens are used for painful bone metastases. Routine use of single fraction treatment might or might not be the preferred institutional approach. It is not entirely clear why inter-physician and interinstitution differences continue to persist despite numerous ...
