Review article: non-systemic chemotherapy in the treatment of colorectal cancer-portal vein, hepatic arterial and intraperitoneal approaches Buecher B; Bleiberg HAliment Pharmacol Ther 2001[Oct]; 15 (10): 1527-41Loco-regional chemotherapy, an alternative to systemic chemotherapy in the management of colorectal cancer, has been evaluated in both adjuvant and palliative settings. The rationale for loco-regional delivery is to achieve higher dose concentrations of drugs at the tumour site or at the most common sites of tumour recurrence, while limiting systemic exposure and associated toxicity. Adjuvant intraportal chemotherapy and palliative hepa-tic arterial chemotherapy have been most extensively investigated. Intraperitoneal chemotherapy has also been studied as an adjuvant treatment after complete resection of colorectal cancer or cytoreductive surgery in patients with established peritoneal carcinomatosis. The results obtained have been disappointing, and none of these procedures can be considered as a standard therapeutic option today. However, methodological difficulties were encountered in most published studies, and the investigated schedules and doses may not have been optimal. New combinations of cytotoxic drugs and new indications are currently under consideration. Promising results have recently been published for adjuvant intraperitoneal chemotherapy and hepatic arterial chemotherapy following surgical resection of hepatic metastases, but additional well-designed multicentre phase III trials are needed to determine the true benefits of these treatment modalities and to address the issues of cost and quality of life.|*Hepatic Artery[MESH]|*Portal Vein[MESH]|Antimetabolites, Antineoplastic/*administration & dosage/therapeutic use[MESH]|Antineoplastic Combined Chemotherapy Protocols/*administration & dosage/therapeutic use[MESH]|Colorectal Neoplasms/*drug therapy/surgery[MESH]|Humans[MESH]|Infusions, Parenteral/methods[MESH]|Peritoneal Neoplasms/*drug therapy/surgery[MESH]|Randomized Controlled Trials as Topic[MESH] |
