How does treatment at a high-volume institution impact overall survival in STS?
No significant association between socioeconomic factors and overall survival (OS) was found in patients with soft tissue sarcoma (STS) treated at a high-volume institution, according to a retrospective analysis at a single institution.
Of the 435 patients included, 37% had grade 3 tumors, 44% had disease >5 cm, and 38% were privately insured. More than half (52%) of patients received neoadjuvant therapy prior to resection.
According to the study, “median distance from the treatment center was 42 miles and median area deprivation index (ADI) was 5 (10 representing most deprived communities).”
Multivariate analysis found that higher tumor grade, tumor size >5 cm, and involved lymph nodes were significantly associated with OS.
The following factors were not found to be associated with OS:
Age at diagnosis
Urban vs. rural location
Distance to the treatment center
“Treatment at a high-volume institution may mitigate the importance of socio-economic factors in the OS of STS,” the authors concluded.
