title: [Mixed prostatic carcinoma: a report of 5 patients and literature review].
abstract: OBJECTIVE
  To improve the awareness of rare mixed prostatic carcinoma.
  
  
  METHODS
  We reviewed the clinical data of 5 patients with prostatic mixed tumor and relevant literature to explore diagnosis and treatment for it.
  
  
  RESULTS
  Patient 1 with mixed small cell carcinoma and adenocarcinoma of the prostate who underwent transurethral electrovaporization of the prostate (TUVP) and flumamide therapy died of lung metastasis 7 months later. Patient 2 with mixed small cell carcinoma and adenocarcinoma of the prostate who underwent TUVP and bilateral testicular resection died of lung metastasis 10 months later. Patient 3 with adenosquamous carcinoma of the prostate who underwent TUVP, radiation therapy and flumamide therapy died of multiple organ failure 8 months later because of the lung, liver, and multiple bone metastasis. Patient 4 with prostatic adenosquamous carcinoma who underwent cystoprostatectomy combined with urinary diversion has already survived for 1 year. Patient 5 with prostatic carcinosarcoma who underwent cystoprostatectomy, urinary diversion, pelvic lymphadenectomy, and radiation therapy died of lung metastasis 13 months later.
  
  
  CONCLUSIONS
  Mixed prostatic carcinoma is quite aggressive with bad prognosis. Its diagnosis relies on detailed pathological examination and immunohistochemical techniques. Patients with prostate adenocarcinoma should be followed up timely after endocrine treatment or radiotherapy. Radical surgery is most effective for mixed prostatic carcinoma.
