A Chi-square test was used to identify differences in the rate of deterioration in ECOGPS between 1 and 6 months after surgery. Improvement or deterioration of subjective health status values was defined as a change in more than one level in the ECOGPS and more than 10 points in the Barthel index. Abbreviations: ECOGPS, eastern cooperative oncology group performance status; BI, Barthel index; BMCB, bone metastasis cancer board.
