Prognostic Factors for Survival in Advanced Cancer Patients in Iceland
Over 150 different factors have been evaluated with regard to prognostication in cancer in various studies. The most common are performance status, cognitive function, quality of life (QoL), physical symptoms and signs, concomitant diseases and biochemical related factors. The aim of this thesis is...

The most common are performance status, cognitive function, quality of life (QoL), physical symptoms and signs, concomitant diseases and biochemical related factors. The aim of this thesis is to investigate the prognostic value of cancer characteristics, prevalent physical symptoms (e.g. pain, fatigue and dyspnoea), opioid treatment, mobility, falls, nutrition, cognitive function and QoL.

Firstly, data from Icelandic participants in the European Pharmacogenetic Opioid Study (EPOS) were used (N=150). These patients, who all received opioid treatment due to pain, had cancer and were either on palliative care and/or life-prolonging cancer therapy. Secondly, assessments of patients in palliative care service evaluated with the interRAI Palliative Care (PC) assessment tool, were included (N=116). Statistical analysis was performed with Kaplan Meier survival and Cox regression analyses. Results: Median survival of the patients in the EPOS part of the study was 101 day. In a multivariate Cox regression, variables that significantly predicted shortened survival were greater number of metastases (HR 1.24) and presence of fatigue (HR 1.82). Higher score on Mini Mental State Examination (MMSE) (HR 0.86), the role function scale (HR 0.99) of the EORTC questionnaire and the Brief Pain Inventory (BPI) interference scale (HR 0.91) was significantly related to longer survival. In the study using the interRAI PC assessment tool the median survival was 41 day.
