High risk factors and treatment analysis of local recurrence after Dixon operation of rectal cancer

Objective To investigate the risk factors and treatment of local recurrence after Dixon operation of rectal cancer. Methods The clinical data of forty-seven patients who had local recurrence after Dixon operation of rectal cancer in our hospital from January 2011 to December 2013 was analyzed retrospectively.According to literature review, the high risk factors and treatment methods of local recurrence of rectal cancer in China and abroad were analyzed. Results The treatment methods of patients with local recurrence after anterior resection were radical resection, palliative resection and chemotherapy.The prognosis of patients with radical resection whose overall survival time was (38.202±2.411) months, better than that with palliative resection ( (24.591±2.150) months), better than that with chemotherapy ( (12.833±1.033) months). There was a significant difference in the survival time among the three groups (χ2=30.155, P<0.001). Conclusion Fully understanding of high risk factor can help reduce the probability of local recurrence.For patients with local recurrence of the rectal cancer, radical resection should be performed.In case that radical surgery is not possible, positive treatments should be adopted if the patients are in good physical condition.
