[Surgical treatment and prognosis of primary retroperitoneal malignant tumor].

OBJECTIVE

To investigate the surgical treatment and prognosis of primary retroperitoneal malignant tumor.

METHODS

A total of 191 patients with primary retroperitoneal malignant tumor treated from January 1996 to December 2007 at our hospital were retrospectively analyzed. SPSS 13.0 was used to analyze the follow-up data.

RESULTS

The clinical manifestations included abdominal mass [122 (63.9%)], abdominal pain [77 (40.3%)] and abdominal distension [48 (25.1%)]. Liposarcoma [75 (39.3%)] was more frequently encountered than other tumors. Among these patients, 142 underwent complete resection, 35 palliative resection and 14 exploratory operation. The median survival time of complete resection, palliative resection and exploratory operation were 56, 33 and 11 months respectively. The difference was of statistical significance.

CONCLUSIONS

Surgical resection is an effective therapeutic method for primary retroperitoneal malignant tumor. Complete resection prolongs the survival time and it is effective in control of recurrent tumors.
