title: Outcomes of surgical treatment alone in patients with superficial soft tissue sarcoma regardless of size or grade.
abstract: OBJECTIVE
  Currently, standard treatment of soft tissue sarcoma (STS) is wide local excision and adjuvant radiation, but radiation may be unnecessary in superficial STS. The primary objective is to assess local recurrence rates in patients treated with surgical management alone for superficial STS.
  
  
  METHODS
  A retrospective cancer registry review of patients treated with surgery alone for superficial STS at the Tom Baker Cancer Center (TBCC) was performed. Patient and tumor characteristics as well as recurrence data were collected.
  
  
  RESULTS
  Sixty-one patients met study criteria. Local and overall recurrence rates were 7/61 (11.5%) and 12/61 (19.7%), respectively. The proportion with a T2 tumor was 38.8% versus 33.3% (P = 0.69), with Grade 2 or 3 tumors was 59.2% versus 83.3% (P = 0.14), and with resection margins <1 cm was 28.6% versus 75.0% (P = 0.008) for patients without and with recurrence, respectively. Median time to recurrence was 1.7 (0.4-5.2) years.
  
  
  CONCLUSIONS
  Surgical resection alone appears to be a viable option for superficial STS that can save patients from potential side effects of radiation. The association between recurrence and inadequate margins (<1 cm) requires additional treatment be offered to this subset of patients.
