Abstract
Management of patients with irresectable stage IV colorectal cancer is controversial. Since 2000, we have favoured primary chemotherapy with stent insertion in case of obstructive tumor. Our aim was to report the results of this strategy in an unselected consecutive series of patients. From 2000 to 2007, 68 of 115 consecutive patients admitted with stage IV colorectal cancer were considered irresectable. Data were collected prospectively. Feasibility and outcomes were analysed in an intention to treat basis. Of 68 patients, 37 received the intended primary chemotherapy, with stent insertion in 19, 13 required surgery as initial management and 18 patients received supportive care only. Twelve patients in the primary chemotherapy group developed local complication, including bowel obstruction in 9, successfully managed by stent in 6 of them. In patients requiring surgery at presentation, mortality and morbidity were 31% and 77%, respectively. Overall, 41 patients received chemotherapy, of whom, 6 were downstaged to undergo curative resection. Median survival was 6.7 and 15.4 months for the whole series and patients treated by primary chemotherapy, respectively (p<0.0001). On multivariate analysis, age, CEA level, primary chemothe...Continue Reading
