Effect of hepatic cryotherapy on serum CEA concentration in patients with multiple inoperable hepatic metastases from colorectal cancer.
Eleven patients with multiple hepatic metastases from colorectal cancer, all judged inoperable, were treated by cryotherapy using a probe through which liquid nitrogen was circulated using a single freeze thaw sequence. Localization of metastases, positioning of the probe and monitoring of ice ball size was by intra-operative ultrasound. Serum carcinoembryonic antigen (CEA) was measured in these patients: there was a postoperative fall in all but two. In all but one, there has been a subsequent rise. Speed and degree of rise of CEA varied between patients. Serial CEA may be an effective means of monitoring the effect of hepatic cryotherapy.
