Abstract:Objective To study the causes of local recurrence, and diagnosis and treatment outcome of recurrent colorectal cancer.
〖WTHZ〗Methods The clinical data of 60 patients with recurrent colorectal cancer treated during 10 years in our hospital were analyzed retrospectively.
Results Among the 60 cases, 40 cases (66.7% ) had recurrence within 2 years after operation. Recurrence in anastomotic stoma, perineum, abdominal incision occurred and in the abdominal cavity and pelvic cavity in 15, 10,7 and 20 cases respectively, and liver metastases were found in 8 cases. All patients underwent reoperation including curative surgery for 38 patients and palliative operation for 22 patients. After radical reoperation the 1,3, and 5yearsurvival rate was 93.6%, 48.8%, and 36.3%, respectively, and after palliative reoperation was 54.5%, 0%, and 0%, respectively.
Conclusions Emphasizing the application of notumor touch technique, resection of adequate amount of bowel, performing complete lymphadenectomy and removal of micrometastatic lesions are the major measures to prevent recurrence of rectal cancer after operation. Integrative therapy regimens，of which surgical treatment is the major component，should be considered according to the location of recurrence and the clinical staging of the recurrent cases.
