AIM: 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.
CONCLUSION: Sufficient preoperative preparation and complete tumor resection play important roles in reducing recurrence and improving survival.
