ABSTRACT
Gastrointestinal (GI) sarcomas are uncommon tumors with the majority of previous studies performed over long time intervals. The purpose of this review is to analyze our single-institution experience with primary GI sarcomas. Between January 1990 and June 1998, 27 adult patients with primary GI sarcomas were identified in the tumor registry at the University Hospital, School of Medicine of University of Alabama at Birmingham and retrospectively reviewed. Patient, tumor, and treatment factors as well as expression of p53 and Ki-67 were analyzed with overall survival as the main outcome variable. Statistical analysis was performed by log rank test and Cox regression. Significance was defined as P < 0.05. Median age was 55 years (range 36-80 years). The stomach was the most common site of presentation (59%) followed by small bowel (29%). The average tumor size was 15 cm (range 2-46 cm). A complete resection was performed in 22 patients (81.5%). Fifteen tumors were classified as low grade (55.5%). Actuarial 3-year survival was 43 percent with a median follow-up of 16 months. Overexpression of p53 and Ki-67 correlated with a trend to decreased survival but it did not reach statistical significance. Multivariate analysis found incomplete resection (P = 0.00001) and high grade (P = 0.003) to be significant negative prognostic factors. We conclude that GI sarcomas tend to be large tumors with most arising in the stomach and proximal GI tract. Complete surgical resection is associated with prolonged survival and despite the large size of these tumors should be attempted whenever possible.
