title: [Re-evaluation of the clinical significance of TNM staging of mid-low rectal cancer].
abstract: The concept of "diagnosis priority using the normalized methods" is the foundation for individualized treatment. A multidisciplinary team, including colorectal surgeons, radiologists and pathologists, should be established for the patients of mid-low rectal cancer. In order to ensure the scientific treatment strategies, reasonable methods of clinical imaging should be arranged to obtain precise clinical TNM staging of pre-therapy. Preoperative neoadjuvant chemoradiotherapy should be performed for the patients of middle-low rectal cancer, whose cancer staging is cT3-4 or cN1-2. The emphasis of the seventh edition of AJCC TNM staging in rectal cancer is to determine what T3 carcinoma is. The basic principle of normalization of mid-low rectal cancer is to achieve R0 resection according to preoperative staging, and to administer comprehensive adjuvant therapy with the evaluation of pathological staging.
