早期胃癌患者的预后相对较好，然而仍有少数淋巴结转移阴性的早期胃癌患者死于术后肿瘤复发或远 处转移，有学者提出淋巴结微转移是这类患者复发与转移的潜在原因。相比于宏观淋巴结转移，淋巴 结微转移的检测更为困难，其对胃癌预后的临床意义仍存在争议。笔者就胃癌淋巴结微转移的研究进 展作一综述。
Lymph node micrometastasis in gastric cancer: research advances
Prognosis for patients with early gastric cancer is relatively favorable, however some of them with negative lymph nodes will still die from either postoperative recurrence or distant metastases. Some researchers proposed that lymph node micrometastasis is a potential cause for recurrence and metastasis in these patients. Detection of lymph node micrometastasis is more difficult compared to that of macroscopic lymph node metastasis, and its impact on prognosis of gastric cancer remains controversial. The authors, in this paper, address the research progress in lymph node micrometastasis of gastric cancer.
