Background: We present a 20-year surgical experience with spermatic cord sarcoma, describe prognostic features, and evaluate the results of surgical and adjunctive treatments.
Methods: Forty-seven patients were identified from an institutional database. Disease-free survival was calculated, and prognostic factors such as tumor grade, size, extent of operation, and adjuvant therapy were analyzed.
Results: The median patient age was 58 years (range, 16-83 years), and the median follow-up was 51 months (range,.5-226 months). The most common tumor types included liposarcoma (51%), leiomyosarcoma (19%), embryonal rhabdomyosarcoma (13%), and malignant fibrous histiocytoma (11%). Twenty-nine (62%) patients had high-grade tumors, 21 (45%) were treated with adjuvant radiation, and 9 (19%) received chemotherapy. The overall 5- and 10-year disease-specific survival was 75% and 55%, respectively. No specific prognostic factors were identified for recurrence or disease-free survival. In 21 patients who underwent reoperative wide resection after a prior incomplete resection, a trend toward improved disease-free survival was noted (P <.059). Of these, six (29%) had residual viable sarcoma. We could not demonstrate a therapeutic effect of adjuvant radiation or chemotherapy.
Conclusions: We demonstrated that aggressive surgical strategies, including reoperative wide resection, significantly decrease local recurrence and may improve disease free-survival in select patients with spermatic cord sarcoma.
