Abstract:

Objective To summarize clinical experience in surgical treatment of primary retroperitoneal tumor(PRT). Methods 75 cases of PRT diagnosed in our hospital from January 2000 to December 2011 were analyzed retrospectively. Results Of the patients, 26 cases were benign tumors(diameter 5～38cm and average 14.33cm) and 49 cases were malignant tumors(diameter 4～22cm and average 8.50cm), including 23 cases and 38 cases were individually taken complete excision. There was no statistical significance between the complete excision differences. 57 patients were followed up after surgical treatment, of which the 1-, 3- and 5-year survival rate was 94.74%, 84.21%, 78.95% and 55.26%, 23.68%, 15.79% in benign and malignant cases respectively. All the differences beween them had notable statistical significance. Moreover, When compared to palliative resection cases, the 1-, 3- and 5-year survival rate in the complete excision cases with malignant PRT were significantly elevated, respectively. Conclusion Adequate preoperative preparation, right surgical approach and proper resection method make operation easy, successful, and reduce operative complication as well. Complete and radical resection is the most critical strategy for PRT surgical treatment, which profit to postoperative survival rate improvement.
