Summary
Brief summary (as posted)
Colorectal cancer is the most-common cancer of the gastrointestinal tract. The number of positive lymph nodes and total number of lymph nodes retrieved are important prognostic factors. In patients who do not receive preoperative chemoradiation, the total number of lymph nodes should be more than 12 nodes to predict accurate staging. In cases of locally-advanced rectal cancer when patients receive neoadjuvant chemoradiation it is sometimes impossible to retrieve adequate amount of lymph nodes due to the chemoradiation effect. Therefore, this study was to evaluate and predict survival rates based on positive lymph node ratio.
