| Abstract: | Objective To present our institutional experience with adult prostate sarcoma over 30 years. Materials and Methods We reviewed 38 cases of adult prostate sarcoma diagnosed and treated at our institution between 1982 and 2012. Univariate Cox proportional hazards regression was used to determine if there was an association between specific disease characteristics (tumor size, histology, American Joint Committee on Cancer stage, and metastasis at diagnosis) and cancer-specific survival (CSS). Results A total of 38 patients were included, with a median age of 50 years (range, 17-73 years). Most men presented with lower urinary tract symptoms (45%), hematuria (24%), or acute urinary retention (21%). Diagnosis was established with prostate needle biopsy (68%) or transurethral resection of the prostate (18%). The predominant histologic subtypes were leiomyosarcoma (13 cases, 34%) and rhabdomyosarcoma (12 cases, 32%). Rhabdomyosarcoma was associated with poorer CSS (hazard ratio, 3.00; 95% confidence interval [CI], 1.13-7.92; P =.027) compared with leiomyosarcoma. We did not observe a significant relationship between tumor size and CSS. Overall, median CSS was 2.9 years (95% CI, 1.5-5.4), with 7.7 years for clinically localized disease (95% CI 2.5; upper bound not reached) and 1.5 years for metastatic disease (95% CI 1.1, 2.7). Conclusion Adult prostate sarcoma has a poor prognosis, especially in cases of metastatic disease at the time of diagnosis. Surgery remains the standard of care, but it provides limited benefit to those with metastatic disease or as a consolidation therapy after partial response to systemic therapy. © 2014 Elsevier Inc.
