title: [Curative effect analysis of radical surgery for colon cancer invading duodenum].
abstract: OBJECTIVE
  To discuss the clinicopathological characteristics and access the immediate- and long-term outcome of radical surgery in patients with colon cancer invading duodenum.
  
  
  METHODS
  A retrospective review of 19 patients with colon cancer invading duodenum underwent radical surgery between 1995 and 2010 was performed. There were 7 male and 12 female, age ranged from 36 to 73 years with an average of 56 years. The main manifestations were abdominal pain, loss of weight, change of stool frequency and so on. The tumors located at the hepatic flexure in 15 patients. All of the patients underwent radical surgery, and none of the patients had positive resection margins. One patient underwent pancreaticoduodenectomy combined with right hemicolectomy (RH). Two patients underwent pylorus preserving pancreaticoduodenectomy combined with RH. One patient underwent duodenectomy combined with RH. Four patients underwent RH. And the other 11 patients underwent lateral duodenectomy combined with RH.
  
  
  RESULTS
  There was no postoperative morbidity and mortality, and the 30-day mortality rate was 0. The median overall survival was 5.3 years. Overall 1 and 5 years survival rate were 94.4% and 70.4%, respectively. And 3 patients developed recurrence in 3 years.
  
  
  CONCLUSIONS
  The patients with colon cancer invading duodenum are lack of specific clinical manifestations. And the radical surgical procedure is safe, which could prolong the survival and improves the prognosis in these patients.
