The authors used the population-based Surveillance, Epidemiology, and End Results (SEER) registry to update what to our knowledge is the largest
series of patients with ASPS reported to date.
Materials/Methods: All patients (n = 132) with a diagnosis of ASPS were obtained in the National cancer Institute’s SEER database
for the years 1973-2003. Univariate and multivariate Cox regression analyses were used to assess the association of clinical,
tumor, and treatment characteristics of patient and survival.
Results: A total of 132 patients with ASPS were identified over 30 years of follow-up.

My comment:
This is the largest statistical data avail. on ASPS so far. It makes incidence of ASPS lower then it was stated before. If we could get the data itself - there might be more then that, we could update a pattern of metastasis at least. They say that sixty-four (48.5%) patients were treated with surgery only, while sixty-three (47.7%) were treated with combination of surgery and radiotherapy - it makes me wonder - were the remaining 5 patients treated with the chemotherapy? Is it all known experience with use of the chemotherapy in USA up to 2003?
