Afamitresgene autoleucel was found be efficacious with favorable tolerability in heavily pretreated patients with advanced synovial sarcoma or myxoid/round cell liposarcoma, according to data from phase 2 SPEARHEAD-1 trial.

Dysregulated platelet-derived growth factor receptor signaling is implicated in a number of cancer types and is among the targets of many FDA-approved multikinase inhibitors.

MEK inhibition combined with an anti-IGFR1 agent shrank tumors in pediatric PAX fusion–negative rhabdomyosarcoma.

Early detection and quick intervention of abdominal metastases in patients with osteosarcoma could be a tactic to improve patient outcomes as well as palliative care.

William D. Tap, MD, discusses the effects of the COVID-19 pandemic on the treatment of patients with sarcoma.

Richard Gorlick, MD, discusses the challenges of identifying immunotherapeutic targets in osteosarcomas.

Intraperitoneal radioimmunotherapy with the anti-B7H3 murine monoclonal antibody 131I-omburtamab was well tolerated with low radiation exposure to normal organs, making it a feasible option to combine with other therapies in patients with desmoplastic small round cell tumor.

The local recurrence rate after surgical excision was similar to the rate of progression with active surveillance in patients with extra-abdominal desmoid tumor fibromatosis, suggesting that observation may be sufficient in some cases.

Richard Gorlick, MD, discusses the potential of antibody-drug conjugates in patients with osteosarcoma.

Selinexor resulted in lower rates and slower worsening of pain in patients with advanced unresectable dedifferentiated liposarcoma vs placebo, and may represent a novel option to provide convenience, improved adherence, and reduced caregiver burden vs existing parenteral therapies.

Reattaching the greater trochanter to the proximal femur endoprosthesis did not show an improvement in Trendelburg gait or reliance on an assistive ambulatory device vs a soft tissue–only abductor repair in patients with bone cancers.
