Portal vein embolization prior to major liver resection.

Background: Portal vein embolization (PVE) induces compensatory hypertrophy of the future liver remnant volume (FLRV) to improve the safety of major liver surgery by reducing the risk of post-operative liver failure. The aim was to describe our experience of PVE for patients with large or multifocal malignant liver tumours who initially were deemed unresectable.

Methods: Perioperative data were retrieved from a prospective database and computed tomographic scans were retrospectively reviewed to calculate volume changes and the degree of liver hypertrophy following PVE.

Treatment of fluorouracil-refractory patients with liver metastases from colorectal cancer by using yttrium-90 resin microspheres plus concomitant systemic irinotecan chemotherapy.

Purpose: Liver metastases are the principal cause of death in patients with advanced colorectal cancer (CRC). Irinotecan is a chemotherapeutic agent used in the treatment of CRC and has demonstrated synergistic potential when used with radiation. Radioembolization with yttrium-90 microspheres has demonstrated increased response and survival rates when given with fluorouracil chemotherapy.
