May inform prognosis counseling in retroperitoneal sarcoma; leaves open need for prospective validation of grade-specific strategies.
Cohort (n=23)
Absolute Event Rate: 44% vs 9%
p-value: p=<0.02
Bautista et al. (2000) conducted a cohort in Retroperitoneal sarcomas (n=23). Low-grade tumor histology vs. Intermediate- or high-grade tumor histology was evaluated on Median survival (months) (p=<0.02). Low-grade retroperitoneal sarcomas were associated with a significantly longer median survival compared to intermediate- or high-grade tumors (44 vs 9 months; P<0.02).
