local control rate
Percentage of patients without local tumor recurrence at a specified time point after treatment.
Full Definition
Local control rate is a key oncological outcome measure representing the percentage of patients who remain free of local tumor recurrence at a specified time interval following treatment. In orthopedic oncology, this metric is crucial for evaluating the effectiveness of surgical resection techniques, adequacy of surgical margins, and overall treatment protocols. Local control rates are typically reported at standardized intervals such as 2, 5, or 10 years post-treatment and serve as important benchmarks for comparing different treatment approaches. Poor local control may indicate inadequate surgical margins, inappropriate patient selection, or suboptimal treatment protocols.
Usage
Usage note: Always specify the time interval when reporting local control rates.
