The lymph nodes ratio (LNR) has been used as a prognostic factor in patients with colon cancer. Few studies have evaluated the impact of LNR on the 5-year survival of ...
INTRODUCTION: Neoadjuvant chemoradiation promotes tumor size reduction and staging before the surgery, reducing the risk of involving the circumferential resection margin and local recurrence. For patients who have been submitted to the neoadjuvant therapy, the usefulness of a second nuclear magnetic res...
