This study was conducted to determine the incidence of inter-observer variability in Eastern Cooperative Oncology Group (ECOG) performance status (PS) rating between patients with leukemia and lymphoma and their physicians. ECOG PS was assessed at diagnosis by patients and their physicians and stratified by disease subtype, gender, age, disease stage and education. Association between patient- and physician-rated PS and overall survival (OS) was stratified by subtype and prognostic risk score. Overall, 65% of patients and physicians rated PS the same. Age, disease stage and disease subtype were significant predictors of PS disagreement. PS was a significant predictor of OS irrespective of assessment by patients or physicians across all subtypes except those with Hodgkin lymphoma. These findings suggest the need for physicians to better communicate with patients when determining PS, as PS is a strong predictor of survival and is critical in treatment decisions, including determining fitness for cancer treatment.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 May 2019.
All research outputs
#9,528,058
of 27,829,204 outputs
Outputs from Leukemia & Lymphoma
#1,234
of 4,577 outputs
Outputs of similar age
#129,192
of 331,879 outputs
Outputs of similar age from Leukemia & Lymphoma
#22
of 71 outputs
Altmetric has tracked 27,829,204 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,577 research outputs from this source. They receive a mean Attention Score of 4.2. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,879 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
We're also able to compare this research output to 71 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
