Task: Answer Verification
Input (English): Question: Is pretreatment quality-of-life score a better discriminator of oesophageal cancer survival than performance status?
Answer: In patients with Stage II-III oesophageal cancer being considered for curative therapy, pretreatment FACT-E and ECS have better discrimination for survival than does ECOG. The majority of patients were ECOG 0/1. Thus, these patient-derived scores were able to discriminate survivors from non-survivors even within this constrained range of clinician-assigned performance status. This highlights the potential utility of FACT-E and ECS as prognostic tools.
Output (English): yes
