[Clinical analysis of 7 cases of adult prostate sarcoma].

OBJECTIVE

To investigate the diagnosis, treatment and prognosis of adult prostatic sarcoma.

METHODS

The records of 7 patients with prostate sarcoma were reviewed in the light of clinical manifestation, laboratory examination, therapeutic methods and histological subtypes. Several clinicopathological variables were assessed for prognostic significance.

RESULTS

Of the 7 cases, 3 were leiomyosarcoma, 3 rhabdomyosarcoma and the other malignant neurilemoma. Most patients presented urinary obstruction, and the diagnosis of prostate sarcoma was established with ultrasound guided biopsy. Histological subtypes were related to the rate of survival. Two patients received radical cystoprostatectomy and died 13 and 21 months respectively after operation. Two cases underwent total pelvic exenteration, followed by chemotherapy and/or radiotherapy and still alive 15 months after operation. The other 3 received only chemotherapy and/or radiotherapy and died 7 months on average after diagnosis.

CONCLUSION

The long-term survival rate for adults with prostate sarcoma is low. Early diagnosis and complete surgical resection offer patients the best chance for survival. Long-term surveillance is necessary for the early detection of recurrence.
