Assessing surgical margins in liver metastases from colorectal cancer during surgery

Prospective Clinical Study of Intraoperative Assessment of Resection Margin of Colo-Rectal Cancer Liver Metastases

Observational Oncology Institute of Vojvodina · NCT04634526

This study is testing how well surgeons can check the edges of liver tumors during surgery for colorectal cancer to see if their findings match what the lab says afterward.

What this trial studies

This observational study aims to evaluate the accuracy of intraoperative assessment of resection margins in patients undergoing surgery for liver metastases from colorectal cancer. Patients will be enrolled after a multidisciplinary team determines the need for surgical resection. Surgeons will assess the resection margins during the operation, and these assessments will be compared to the pathological examination results post-surgery, which serve as the gold standard. The goal is to determine the sensitivity of the surgical assessment in identifying positive and negative margins.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with a preoperative diagnosis of liver metastases from colorectal adenocarcinoma who are indicated for surgical resection.

Not a fit: Patients who have undefined resection margins or those undergoing simultaneous surgical resections and ablative procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes by ensuring more accurate assessments of cancer resection margins, potentially reducing the risk of cancer recurrence.

How similar studies have performed: While similar studies have explored intraoperative assessments, this specific approach to evaluating resection margins in colorectal liver metastases is relatively novel.
