| Abstract |
Current stratification of prognosis in patients with epithelioid sarcoma (ES) is based largely on data reported by individual centers with a limited number of patients. We sought to identify the important prognostic parameters using the Surveillance, Epidemiology, and End Results (SEER) database. We identified 441 patients with ES in the database and extracted information regarding patient demographics and clinical characteristics. Kaplan-Meier, log-rank, and Cox regression were used for analysis. Disease-specific survival declined until 100 months after diagnosis after which survival was unrelated to epithelioid sarcoma. The overall incidence of ES during 2005 was 0.041 per 100,000. The reported incidence has increased since 1973, with an annual percentage change of 5.217%. On multivariate analysis, only age younger than 16 years, local stage of disease, or negative nodes and surgical resection of the tumor predicted better disease-specific survival. We observed no increase in survival by comparing decades of diagnosis since 1986. The SEER database shows only age younger than 16 years, negative nodes, or local stage of disease and operability of primary disease independently predict survival in patients with ES. |

Attention Score in Context
This research output has an Altmetric Attention Score of 43. 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 28 January 2020.
All research outputs
#961,693
of 25,373,627 outputs
Outputs from Clinical Orthopaedics & Related Research
#99
of 7,298 outputs
Outputs of similar age
#2,285
of 108,534 outputs
Outputs of similar age from Clinical Orthopaedics & Related Research
#2
of 41 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 96th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 7,298 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one has done particularly well, scoring higher than 98% 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 108,534 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 97% of its contemporaries.
We're also able to compare this research output to 41 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 95% of its contemporaries.
