BACKGROUND: Soft tissue sarcomas (STSs) arising from the popliteal fossa present a challenge with regard to local control of primary tumors. Due to concerns of functional morbidity and neurovascular compromise, there is debate about what represents the best therapy for these patients. METHODS: We conducted a retrospective medical record review of patients treated at The University of Texas M. D. Anderson Cancer Center for STS of the popliteal fossa from 1990 to 2008 .RESULTS: There were 47 eligible patients, 28 of whom were male and 19 of whom were female. Synovial sarcoma was the most common diagnosis, with 12 cases. Most patients had T2b tumors (31 patients; 66%). The median duration of follow‐up was 3.8 years (range, 0.6‐17.9 years). The 5‐ and 10‐year overall survival rates were 63% and 51%, respectively. Metastasis at diagnosis was associated with poorer overall survival (5‐year overall survival, 74% versus 13%; P <.001) and poorer recurrence‐free survival (5‐year recurrence‐free survival, 51% versus 0%; P <.001) on univariate analysis. Radiation therapy improved local recurrence‐free survival (5‐year local recurrence‐free survival, 56% versus 17%; P = .004), whereas a trend was observed for surgical margin status ( P = .07). Tumor size and neurovascular involvement did not influence outcome. Twenty‐two patients had recurrent disease, with 15 patients having local recurrence, and 16 patients died from progressive disease. CONCLUSIONS: Radiation therapy may play an important role in the treatment of popliteal fossa STS, but further study is needed to better define the best clinical application. Additional study is needed to re‐evaluate association of surgical margin status and outcome. Cancer 2011; © 2010 American Cancer Society.
