Arms (0)

Primary outcomes (2)

1. measure

   Cancer-specific health-related quality of life

   timeFrame

   6 months

   description

   Measured with the European Organization for Research and Treatment of Cancer (EORTC) core QoL questionnaire (QLQ-C30). All items are rated on a 4-point Likert-type response scale of 1 ("not at all") to 4 ("very much"), with the exception of the global health status scale items, which are rated from 1-7. Each subscale will be linearly transformed to a 0-100 scale, according to the EORTC scoring manuals. For the functional and global scales, high scores indicate high level of functioning. For the symptom scales, high scores indicate high symptom burden. Clinically relevant changes (CRCs) in EORTC scores are defined as small (5-10 points), moderate (10-20 points), or large (\>20 points).
