LOS ANGELES, July 28, 2020 /PRNewswire/ -- Research led by the Children's Oncology Group (COG) and NRG Oncology, and supported by the St. Baldrick's Foundation, discovered that adding pazopanib, a type of chemotherapy, to preoperative chemoradiotherapy improves response to treatment for soft tissue sarcoma patients, compared with chemoradiotherapy alone. This is believed to be the first collaborative study by pediatric and adult cancer researchers in soft tissue sarcoma to evaluate a new therapeutic approach in patients across the entire age spectrum. The work appears as an advance online publication today in Lancet Oncology.
Soft tissue sarcomas represent 7% of childhood and 2% of adult cancers, excluding rhabdomyosarcoma, gastrointestinal stromal tumor and Ewing sarcoma, each of which has a disease-defined treatment.
Surgery, with or without radiotherapy, is a common treatment for the 60% of patients with soft tissue sarcoma with small and superficial tumors. Patients with large or deeper tumors have only a 50% cancer for long-term survival even with the addition of intensive chemotherapy to surgery and radiotherapy.
"It is too early to know if the addition of pazopanib will improve the chances for long-term survival," said Dr. Douglas Hawkins, COG Group Chair, "but the increase in response makes us hopeful that we may see improved outcome from the addition of pazopanib over time."
"This new treatment to improve responses for soft tissue sarcoma patients is one of many reasons the St. Baldrick's Foundation is proud to be the largest non-government funder of the Children's Oncology Group," said Becky Chapman Weaver, St. Baldrick's Chief Mission Officer. "Each year a multi-million-dollar St. Baldrick's grant to the COG supports the costs of treating children on clinical trials. This study received additional support as one of the COG's high-impact initiatives. We look forward to supporting more advancements as a result of COG clinical trials in the years ahead."
The success of this study will likely encourage additional joint pediatric and adult studies in soft tissue sarcomas and diseases that extend to various ages in the future.
The research was funded in part by the National Institutes of Health and the St. Baldrick's Foundation.
