淋巴结转移是直肠癌最主要的转移途径,也是根治术后腹腔内局部复发和远处转移的主要原因。近年来,随着影像学技术和分子生物学技术的发展,更准确地检测直肠癌区域淋巴结转移已成为可能,本文就此领域的最新进展作一概述。一、术前检测由于直肠癌转移淋巴结被触诊发现时大多已是 Lymphatic metastasis is the most important metastasis of rectal cancer, and is also the main reason for local recurrence and distant metastasis after radical operation. In recent years, with the development of imaging technology and molecular biology technology, it is possible to detect lymph node metastasis more accurately in rectal cancer area. This article summarizes the latest progress in this field. First, the preoperative detection of metastatic lymph nodes due to colorectal cancer palpation was found mostly when
