Assessing Health-related Quality of Life in Sarcoma Patients

Although the clinical effectiveness of sarcoma treatment has improved, long-lasting and cumulative treatment side-effects may often detract from the overall marginal advantage. Information only on survival is insufficient to determine the net clinical benefit of a treatment. It is important to assess treatment effectiveness both in terms of objective outcomes (e.g., response, recurrence and survival) and in terms of subjective patient reported outcomes (PROs), objective functional outcomes including health-related quality of life (HRQoL). Previous studies have predominantly used generic HRQoL instruments, which cover some relevant issues but do not capture all the unique experiences of patients with sarcoma, and thus lack content validity. A sarcoma-specific questionnaire should be able to detect, with more sensitivity, side-effects, symptoms and problems with function that are particularly relevant to patients with sarcoma. To date , there is no specific sarcoma HRQoL instrument available; and, given the heterogeneity of the disease in terms of subtype, location, age and treatment, the development of such an instrument may be challenging. The aim of this collaborative project between the EORTC Quality of Life Group (QLG) and the EORTC Soft Tissue and Bone Sarcoma Group (STBSG) is to raise the standard of HRQoL measurement in patients with sarcoma. An important question remains to be answered: Is it possible to develop one PROs questionnaire covering HRQoL issues that are relevant to all adult patients with sarcoma, or are the HRQoL issues related to the different localization / treatment sufficiently different to warrant the creation of separate item lists selected from the EORTC QLG Item Library?
