Is pretreatment quality-of-life score a better discriminator of oesophageal cancer survival than performance status?
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.
Sustained cytoplasmic calcium levels are necessary, but not sufficient, for high-level PS exposure in response to agonists. Increased Ca(2+)(mit) levels are a key signal initiating mPTP formation and PS exposure. Blockade of Ca(2+)(mit) entry allows the specific inhibition of platelet procoagulant activity.
