Conclusions
ADVANCED CANCER
In the patients undergoing drug therapy for advanced cancer, the preceding cancer-specific HRQOL instruments were found to impact the mobility and usual activities questions in the EQ-5D-5L. This resulted in a difference in the EQ-5D-5L index; however, our findings indicated that the difference size would not be considerably larger than the MID. Few correlation coefficients between the EQ-5D-5L index and the subscales of the disease-specific HRQOL instruments varied among the instrument orders. The patients tended to complete the EQ-5D-5L when it was placed at the end of the questionnaire.
