tumor contamination
Inadvertent spillage of tumor cells during surgical procedures, compromising oncological outcomes.
Full Definition
Tumor contamination refers to the inadvertent spread or spillage of malignant cells during surgical procedures, which can lead to local recurrence and compromise oncological outcomes. This contamination can occur through various mechanisms including violation of the tumor pseudocapsule, inadequate irrigation, contaminated surgical instruments, or breach of the planned resection margins during surgery. Prevention of tumor contamination requires meticulous surgical technique, appropriate use of barriers, copious irrigation, and adherence to oncological principles throughout the procedure. Recognition and documentation of any contamination events is crucial for postoperative management decisions.
Usage
