debulking surgery
Surgical procedure to remove the bulk of tumor mass when complete resection is not possible.
Full Definition
Debulking surgery involves the surgical removal of as much tumor tissue as possible when complete resection cannot be achieved. This approach is commonly used in ovarian cancer, peritoneal carcinomatosis, and other advanced malignancies. The goal is to reduce tumor burden to optimize subsequent chemotherapy or radiation therapy effectiveness. Success is often measured by residual disease diameter, with optimal debulking typically defined as residual nodules less than 1cm. The procedure may be primary (before chemotherapy) or interval (after neoadjuvant treatment).
Usage
Usage note: Often paired with 'optimal' or 'suboptimal' based on residual disease measurements.
