Radio-chemotherapy as a preoperative treatment for advanced rectal cancer. Evaluation of down-staging and morbidity [PDF]

, 2002
Background: The standard therapy for patients with clinically resectable rectal cancer is generally considered to be surgery, If the patient is diagnosed with advanced disease, postoperative radiochemotherapy (RCT) is usually recommended. In our study we
