Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Overall serious adverse event rate for patients with primary resectable RPS receiving NA short-course h-PBT followed by surgical resection
Secondary outcome measures
Local recurrence-free survival (LRFS)
