MSKCC and IMDC risk classification scores consist of clinical and laboratory parameters, which are able to classify patients prognosis. Baseline health related quality of life (HR-QoL) has been previously shown to have prognostic relevance in cancers. We therefore tested whether the addition of HR-QoL parameters to these tools can improve prognostic accuracy.
1100 1st line patients treated with sunitinib or pazopanib within the COMPARZ study (NCT00720941) were analyzed retrospectively. Baseline FACIT-Fatigue (F), FKSI-19 and the DRS-P subscale were used as continuous variable in prognostic factor analysis. Cox proportional hazards regression was performed to evaluate the potential prognostic ability of HR-QoL parameters on OS. Scores were adjusted for MSKCC and IMDC risk group scores separately.
Univariable analysis on prognosis, adjusted for risk groups.
|IMDC risk FACIT-F||Favorable Intermediate Unfavorable Unknown Continuous||0.77 (0.37, 1.60) 1.42 (0.70, 2.87) 3.10 (1.50, 6.38) REFERENCE 0.97 (0.97, 0.98)|
Our analyses indicate that baseline HR-QoL scores add to established risk prognosticators. However, only a single HR-QoL score should be used for further validation. Further study of discrimination ability is ongoing.
