Modern therapy of rectal carcinoma.

Throughout the past decade the treatment of rectal carcinoma has improved remarkably. Today, individualized multimodality treatment allows local and distant tumor freedom with preservation of anorectal and genitourinary function in a majority of patients. Radiotherapy is elementary in reducing the risk of local recurrence whereas chemotherapy including promising novel agents prevents or eliminates distant metastases. However, surgery revolutionized by TME (total mesorectal excision) remains the only curative treatment for rectal carcinoma. In this study the authors review the developments as well as the current status of modern treatment for rectal carcinoma.
