ABSTRACT

Objective To investigate the diagnosis and treatment of primary retroperitoneal tumor,and improve the early correct diagnostic rate and the resection rate.Method 86 patients with primary retroperitoneal tumor(PRT) were analyzed by review of the clinical materials from 1990 to 2000.Results Abdominal or waist pain was the main symptom,and abdominal or waist mass was the main sign.52.6% percent of the patients got correct diagnosis before operation.62 cases were followed up,the 2-year survival rate for complete resection cases were 61.3%,while the patients who received palliative resection or biopsy died within one year.The resection rate of tumors was 81.3% in benign tumors and 37.7% in malignant tumors,the recurrent rates after complete resection were 15.4%,60%,respectively.Conclusions The earlier diagnosis,totally removal of tumors at first time,periodic examination after operation are three important ways.The operative treatment is very imperative for the patients with recurrence.
