Metastatic Patterns Vary Substantially Between Subtypes of Soft Tissue Sarcoma
Marcos R. Gonzalez, MD, Santiago A. Lozano-Calderon, MD, PhD, and colleagues found metastatic patterns differ widely between subtypes of soft tissue sarcomas in the extremities and pelvis, underscoring the need for subtype-specific management strategies. Even with (neo)-adjuvant treatment, prognosis was dismal.
