For patients with colorectal liver metastasis (CLM), surgical resection is the only hope for cure, but conventional hepatectomy involves mechanical manipulation that could release tumor cells into the bloodstream and result in further spread.
To minimize this risk, an alternative method was introduced in 1992 ― an anterior approach for open right hepatectomies, which involves less manipulation.
However, a trial that compared the two surgical approaches showed no difference between the two in reducing intraoperative tumor cell dissemination.
Circulating tumor cells (CTCs) were detected in 6 of 22 patients (27%) in the anterior hepatectomy group and in 5 of 21 (24%) patients in the conventional hepatectomy group, the study authors report.
