Abstract

Purpose: Inguinoscrotal sarcomas are exceedingly rare tumors. The aim of this study was to enable clinicians an easy and rapid access to the available information on this tumor entity. Methods: An updated series of 21 men treated for sarcoma of the inguinoscrotal region at our institution between 1992 and 2012 was analyzed, and a systematic review of the literature with meta-analysis of outcome data was performed. The review was focused on demographic data, survival rates, prognostic factors, sites of relapse and complete remissions or successful treatments for metastatic disease. Results: With only 38 %, the proportion of high-grade tumors in our sample was lower than reported in the literature and the 10-year relapse-free, disease-specific and overall survival rates were favorable with 77, 93 and 81 %. Beside our series, twelve studies including 345 patients were identified in the literature. The weighed mean 10-year relapse-free, disease-specific and overall survival rates were 63, 64 and 50 %. Only in patients with rhabdomyosarcoma, durable control of metastatic disease has been reported in more than one case (n = 4). Successful treatment in these cases consisted of a combination of complete surgical resection of metastatic lesions, subsequent chemotherapy and (optional) radiotherapy. Conclusions: Overall, about two-thirds of inguinoscrotal sarcomas may be cured. In series with a predominance of low-grade tumors, the long-term survival rates in completely excised inguinoscrotal sarcomas may be as favorable as in testicular germ cell tumors. Life-long surveillance is advisable to detect late recurrences.
