Popis: BackgroundTo identify the clinical and imaging characteristics of soft tissue sarcomas (STS) of the trunk and extremities that undergo unplanned excision.MethodsThis retrospective study evaluated the data of patients with STS in the trunk or extremities between January 2008 and December 2021. Patients were divided into unplanned and planned excision groups based on their initial treatment. The distribution of histologic subtypes was analyzed, and the magnetic resonance imaging features were evaluated. Multivariable logistic regression was performed to identify variables independently associated with unplanned excision.ResultsA total of 305 patients (mean age±standard deviation, 51±16.4 years; 179 males) were analyzed. The most prevalent subtype in the unplanned excision group was myxofibrosarcoma (22.3%). The unplanned excision group had a significantly smaller tumor size (p < 0.001) and more frequent superficial (p < 0.001) locations. Lobulated shape and peritumoral abnormalities were present in 70.0% and 50.0% of the unplanned excision group, respectively. Tumor size (adjusted odds ratio [OR], 0.87 per 1 cm increase; 95% confidence interval [CI], 0.77-0.98; p = 0.025) and superficial location (adjusted OR, 3.48; 95% CI, 1.57-7.72; p = 0.002) were independently associated with unplanned excision.ConclusionMyxofibrosarcoma is associated with a high frequency of unplanned excision. A significant number of patients in the unplanned excision group demonstrated a lobulated shape and peritumoral abnormalities. Only small tumor size and superficial location were independently associated with unplanned STS excision.
