title: [Local recurrence in colon and rectal cancer].
abstract: Data on the incidence of colorectal cancer are alarming and reveal that it is currently the second cause of death from cancer. Most of these deaths are due to recurrence after surgery with curative intent. The factors associated with locoregional recurrence are mainly related to the tumor's histopathological characteristics and grade of invasion. With adequate training the surgeon should not appear among these factors. In rectal cancer this training involves the technique of mesorectal excision, adequate circumferential margin and selective neoadjuvant chemoradiotherapy. After curative resection, patients should be followed-up to detect asymptomatic recurrence. Isolated local recurrence occurs in 20-30% of patients, but even with liver or lung metastases curative surgery can be attempted and success depends on correct multidisciplinary preoperative evaluation. If the diagnosis is made when the tumor is in an incurable phase, the aim is to improve the patient's quality of life.
