Neoadjuvant chemotherapy in the management of colorectal metastases: a review of the literature Ann Acad Med Singapore. 2003 Mar;32(2):205-11 PMID: 12772524 Larger series have reported resectability rates ranging from 10% to 40% for unresectable colorectal liver metastases after treatment with preoperative chemotherapy. Chemotherapy generally consisted of oxaliplatin added to 5-fluorouracil/leucovorin administered in a chronomodulated fashion. Preliminary data from a recent study suggest that initial treatment with an oxaliplatin-containing regimen may lead to a higher resectability rate compared to an irinotecan-containing combination (18% versus 7%). A median of about 5 to 10 months of treatment was necessary for adequate tumour reduction. The 5-year survival rates, after surgery, in completely resected patients were between 30% and 60%. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12772524&dopt=Abstract
