Abstract

3593 Background: Although surgical resection remains the treatment of choice for liver metastases from colorectal cancer, only a minority of pts are suitable for surgery. Preoperative chemotherapy allows secondary liver resection and subsequent long-term survival in some patients (pts)with unresectable CCR liver metastases Methods: The aim of this study was to evaluate the safety and efficacy of oxaliplatin 120 mg/m2 day 1, CPT-11 150 mg/m2 day 1 and 14, fluorouracil 2600 mg/m2 days 1 and 14 and folinic acid 500 mg/m2 days 1 and 14, every four weeks, in metastasic liver CCR patients either technically unresectable or with known poor prognostic factors for long term survival after surgery. Results: 39 pts (M/F: 30/9), median age 55 (28–77), median ECOG 1 (0–2) were included. Mean number of liver nodes and mean size were 6.7 and 6.1 cm, respectively. 22 pts (56.4%) were initially unresectable while 17 (43.6%) had poor prognostic factors including large tumor size (52.9%), multinodular (23.5%), ill-located (...
