    • How we treat octogenarians with brain metastases 

      Nieder, Carsten; Andratschke, Nicolaus H.; Grosu, Anca L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-08)
      Biologically younger, fully independent octogenarians are able to tolerate most oncological treatments. Increasing frailty results in decreasing eligibility for certain treatments, e.g., chemotherapy and surgery. Most brain metastases are not an isolated problem, but part of widespread cancer dissemination, often in combination with compromised performance status. Multidisciplinary assessment ...
