Multidisciplinary Treatment of Inguinoscrotal Sarcomas: Analysis of 39 Cases Treated by Surgical Approach.

[BACKGROUND] Inguinoscrotal sarcomas are a rare sarcoma subtype. The treatment of choice is radical inguinal orchiectomy with wide local resection of the surrounding soft tissues. However, consensus regarding prognostic factors is lacking. We present our experience at a referral sarcoma center concerning the management, oncologic results, and prognostic factors pertaining to this disease.

[METHODS] We conducted a retrospective analysis of patients who underwent surgery for inguinoscrotal sarcomas between 2005 and 2023 at a sarcoma referral hospital.

[RESULTS] The study included 39 patients. The most frequent histology was liposarcoma. Seven patients required surgical reconstruction with a microvascularized free flap. Four patients presented major postoperative complications. Mean follow-up was 46 months. Overall survival rates were 97.4%, 81.7%, and 64.8% at one, three, and five years. High-grade tumors were correlated with worse overall and disease-free survival.

[CONCLUSIONS] The chance finding of a sarcoma in the inguinal region poses a diagnostic and therapeutic dilemma when considering options for treatment with curative intent. Vascular and muscle resection followed by vascular and/or free flap reconstruction may be necessary to achieve complete surgical resections; therefore, a multidisciplinary approach is needed. A preoperative biopsy should be performed to establish the histological grade, which may be the main prognostic factor.
