EORTC Research Fellow wins New Investigator award at 2012 ISOQOL Conference

26/10/2012

Divine E. Ediebah, Research Fellow in the Quality of Life Department (QLD) at EORTC Headquarters, received the New Investigator Award at the 2012 International Society for Quality of Life Research Annual Conference (ISOQOL). The New Investigator Award is based on Divine’s research efforts in the QLD concerning biostatistical analyses on clinical trials data in the Patient Reported Outcome and Behavioral Evidence (PROBE) projects and working in collaboration with the EORTC Lung Cancer Group. Specifically, the award recognizes his analysis of joint modeling of longitudinal health-related quality of life (HRQoL) data and overall survival in non-small-cell lung cancer (NSCLC) patients.

In cancer clinical trials, outcomes may co-vary; treatment-related impairment of HRQoL may hasten death, and thus mask survival benefits of treatment. Divine analyzed data from a clinical trial comparing gemcitabine+cisplatin (arm B) and paclitaxel+gemcitabine (arm C) versus paclitaxel+cisplatin (arm A, the standard arm) in 480 advanced stage NSCLC patients. HRQoL was assessed via the global health status/QOL (GHS) scale of the EORTC QLQ-C30 questionnaire at baseline and after each chemotherapy cycle. Joint modeling was used to assess the combined effect of treatment on HRQoL and survival.

Results of the analysis suggest that part of the survival benefit of a new treatment can be masked by the negative effect that treatment has on HRQoL. Up to 27% of the theoretical treatment efficacy was lost through impaired HRQoL affecting survival. The results of this analysis also support the association between HRQoL and overall survival: increased attention to effective supportive care during treatment could potentially correct negative HRQoL effects and unmask survival benefits.

Dr. Andrew Bottomley, Assistant Director and Head of the EORTC QLD said “this is excellent work, and gives that chance for young researchers to see how important the work that Divine is undertaking and which will hopefully can lead to improvements in patient care.”
