  • Title: Fibrous soft tissue tumors: factors predictive of recurrence.
    Author: Aldrink JH, Nicol K, Wang W, Teich S.
    Journal: J Pediatr Surg; 2013 Jan; 48(1):56-61. PubMed ID: 23331793.
    Abstract:
    BACKGROUND/PURPOSE: Fibrous soft tissue tumors (FSTT) of infancy and childhood present a challenge to surgeons due to ambiguous histological interpretation, propensity for local recurrence, and uncertainty regarding appropriate therapy. METHODS: Records were reviewed for patients diagnosed and treated for FSTT at our institution from 1992 to 2010. Data included demographics, tumor location, operative treatment, histopathology, margin status, mitotic index, and recurrence. RESULTS: Eighty-six patients underwent treatment of FSTT. Mean follow-up time was 62 months (range 1 to 201 months). There were 11 recurrences (13%), with a mean time to recurrence of 23 months. Extremity and digital lesions were most likely to recur with 21% of such lesions recurring compared to 7% of lesions located elsewhere. Recurrences were seen more frequently in older children. Despite the presence of positive margins in 92% of cases, margin status, histopathology, and mitotic index were not significant predictors of recurrence. CONCLUSIONS: Digital and extremity fibrous soft tissue tumors and tumors of older children have an increased risk for local recurrence. Margin status did not predict recurrence rates in this series. While the surgical goal is to obtain complete local resection with clear margins, this may be challenging in particular locations and may not ultimately impact recurrence.
