Prognostic and predictive factors in undifferentiated pleomorphic sarcoma: A long‐term study from a large tertiary care urban center

Abstract

UPS displays high rates of metastatic disease and local recurrence. Using a tumor size cutoff value of 7 cm yields superior prognostic value than the standard STS T-score thresholds. Lymphovascular invasion is an important risk factor for the development of metastasis.
