OBJECTIVE
The purpose of this study was to evaluate local control, survival and complication rate after treatment of soft tissue sarcoma (STS) with limb-sparing surgery combined with pulsed-dose rate (PDR) interstitial brachytherapy (BRT) and external beam radiotherapy (EBRT).
METHODS
A retrospective review of 39 adult patients (female/male=25/14, mean age 51(range 21-78) years) with STS who underwent primary limb-sparing surgery combined with PDR BRT (20Gy) and additional post-operative EBRT (50Gy) during the years 1995-2004.
RESULTS
Five patients developed local recurrence after a mean follow-up of 3.4 (1.5-5.9) years. The probability of local recurrence free 5 years survival was 83%. At the time of follow-up 10 patients had died (mean follow-up 2.3 (0.8-7.1) years) and 29 patients were still alive (mean follow-up 5.9 (2.1-11.2) years). The overall 5-year survival rate was 76%. Nineteen (49%) patients suffered from some degree of decreased force or function of the affected extremity, 16 (41%) suffered from oedema, 12 (31%) had persistent pain, 8 (21%) suffered from wound complications, and in 4 (10%) of these patients plastic surgery were required.
CONCLUSIONS
Limb sparing surgery, combined with PDR BRT and EBRT can result in good local control in patients with soft tissue sarcomas. BRT is an effective modality with good cosmetic results and acceptable toxicity.
