title: [Primary peritoneal malignant tumor: clinical analysis of 28 cases].
abstract: OBJECTIVE
  Primary malignant peritoneal tumor is a kind of rare malignancy. Its morphology and clinical manifestations are very similar to the advanced ovarian cancer, therefore, they are usually misdiagnosed and the proper treatment were delayed. This paper analyzed the clinical characteristics, diagnosis, treatment, and prognosis of primary malignant peritoneal tumor.
  
  
  METHODS
  The clinical data of 28 cases of primary peritoneal malignant tumor patients admitted between January 1996 to February 2002 in People's Hospital, Peking University, was analyzed retrospectively. There are 20 cases of primary peritoneal seropapillary adenocarcinoma, 8 cases of primary peritoneal malignant Muellerian tube tumor. Their age ranged from 33 to 74, with median age of 54.
  
  
  RESULTS
  Among 28 patients, 22 were misdiagnosed preoperatively, the misdiagnose rate were 79%. In all cases, cytoreductive surgery were performed. Postoperative chemotherapy were given either with CAP regimen or TP regimen. Postoperative survival time was 1-83 months, the median survival time was 30 months.
  
  
  CONCLUSIONS
  The recognition of this special tumor should be stressed, to improve early diagnosis and treatment. The authors suggest that cytoreductive surgery on time and postoperative adjuvant chemotherapy should be implemented to improve survival rate.
