title: Surgical management of 143 patients with adult primary retroperitoneal tumor.
abstract: OBJECTIVE
  To analyze the surgical management of adult primary retroperitoneal tumors (APRT) and the factors influencing the outcome after operation.
  
  
  METHODS
  Data of 143 cases of APRT from 1990 to 2003 in the First Affiliated Hospital of China Medical University were evaluated retrospectively.
  
  
  RESULTS
  A total of 143 cases of APRT were treated surgically. Among them, 122 (85.3%) underwent complete resection, 16 (11.2%) incomplete resection, and 3 (3%) surgical biopsies. Twenty-nine (20.2%) underwent tumor resection plus multiple organ resections. Ninety-five malignant cases were followed up for 1 mo to 5 years. The 1-year, 3-year, and 5-year survival rates of the patients subject to complete resection was 94.9%, 76.6% and 34.3% and that of patients with incomplete resection was 80.4%, 6.7%, and 0%, respectively (P < 0.001). The Cox multi-various regression analysis showed the completeness of tumor, sex and histological type were associated closely with local recurrence.
  
  
  CONCLUSIONS
  Sufficient preoperative preparation and complete tumor resection play important roles in reducing recurrence and improving survival.
