The role of adjuvant chemotherapy in colon cancer.

Surgical resection of the primary and regional lymph nodes is still, at this time, the standard treatment of colon cancer. However, the risk of recurrence is still high in many patients. Efforts of the past decades have proved the role of systemic chemotherapy in the adjuvant setting in improving the curative rates. The combination of 5-fluorouracil (5-FU)and leucovorin (LV) remains the cornestorne of colon cancer chemotherapy worldwide. The addition of Oxaliplatin to infusional 5FU/LV has been shown to prolong significantly disease-free survival and capecitabine may be considered as an alternative to 5-FU/LV in the adjuvant therapy of stage III colon cancer. Novel molecular and biological-oriented agents are being studied, with promising date.
