- W3029129958 abstract "Objective To investigate the clinical presentations, pathologic features, and the di-agnosis and treatment of prostate sarcomatoid carcinoma. Methods Two cases of prostate sarcoma-told carcinoma were analyzed with review of the relevant literature. Case 1, a 51-year-old man com-plained of dysuria and perineal discomfort for 2 months, was admitted because of acute urinary reten-tion. His serum PSA was 2.31 ng/ml. Heterogeneous density of the prostate left lobe and bladder neck involvement was shown on CT scan. Prostate sarcomatoid carcinoma was confirmed by transrec-tal prostate biopsy, and patient accepted radical cystoprostatectomy and ideal conduit followed with lo-cal radiotherapy and hormonal therapy. Case 2 was a 54-year-old male. This ease was admitted with a history of dysuria and intermittent gross hematuria for 1 month. Hypoechoic lesion was found by ul-trasonography,and heterogeneous density of the prostate was shown on CT scan. His serum PSA was 2.61 ng/ml. The prostate biopsy result showed prostate sarcoma. Radical cystoprostatectomy and ide-al conduit was performed on this case. Results The diagnosis of prostate sarcomatoid carcinoma in the 2 cases was confirmed by postoperative pathology. Under microscope, the neoplasm was mainly composed of epithelial and sarcomatoid mesenchymal cells,with a transitional region of these cells. Im-munohistochemical staining showed that the cells were positive for cytokeratin and epithelial membrane antigen. Vimentin was negative in the epithelial cells, but was positive in the majority of sarcomatoid cell. Both patients died of multi-metastasis at 43 and 19 months after surgery respectively. Conclu-sions Sarcomatoid carcinoma of the prostate is extremely rare with a high grade of malignancy,and its prognosis is poor. The diagnosis depends on pathological features and immunohistochemical studies. Radical resection combined with endocrine therapy and radiotherapy is considered to be the most relia-ble treatment so far.Key words: Prostatic neoplasms; Sarcomatoid carcinoma; Pathology" @default.
