Abstract:
OBJECTIVETo investigate the diagnosis, treatment and prognosis of sarcoma of the adult prostate.
METHODSWe reported 6 cases of sarcoma of the adult prostate, of which 3 were leiomyosarcoma, 2 rhabdomyosarcoma and 1 malignant neurilemoma, 2 at Ghavimi Stage II, 3 at Stage III and 1 at Stage IV. The patients were aged from 18 to 44 years (mean 31 years) and their disease course ranged from 3 to 12 months (mean 7 months). Five of them received operation, radiotherapy and / or chemotherapy and 1 underwent cystostomy only.
RESULTSImmunohistochemical dyeing showed vimentin to be positive while PSA and PAP negative in all the 6 cases, actin (HHF35) positive in the cases of leiomyosarcoma and rhabdomyosarcoma, and S-100 and lysozyme positive in the case of malignant neurilemoma. One case failed to be followed up, and the other 5 died 2-11 months after the operation.
CONCLUSIONSarcoma of the adult prostate initiates with the symptom of progressive dysuria, which can be diagnosed by DRE test and confirmed by needle biopsy. Early diagnosis and radical surgical resection may offer the best chance of survival, but with poor prognosis.
