locoregional recurrence
Return of cancer in the same anatomical region as the primary tumor or adjacent lymph nodes.
Full Definition
Locoregional recurrence refers to the reappearance of cancer within the original tumor bed, surgical scar, or regional lymph node basins following treatment. This pattern of recurrence is distinguished from distant metastases and has different implications for treatment options and prognosis. Locoregional recurrences may be amenable to salvage surgery or regional therapies, whereas distant recurrences typically require systemic treatment. The time interval to locoregional recurrence and the pattern of failure provide important prognostic information.
Usage
Usage note: Clearly distinguish between local recurrence (tumor bed) and regional recurrence (lymph nodes) when possible.
