肺癌是人类最常见的恶性肿瘤,近年来其发生率和死亡率均呈上升趋势。但肺癌的疗效数十年来无明显提高,5年生存率仅10%～15%,究其原因转移是影响肺癌预后的主要因素之一,而淋巴转移又是肺癌转移的主要途径,肺癌引流区淋巴结的免疫状况可能成为肺癌转移的主要因素。现将关于肺癌淋巴结引流区的免疫状况做一综述。 Lung cancer is the most common malignant tumor in humans, and its incidence and mortality have been on the rise in recent years. However, the efficacy of lung cancer has not improved significantly over the past decades and the 5-year survival rate is only 10% -15%. The reason for this is that metastasis is one of the major factors that affect the prognosis of lung cancer. However, lymphatic metastasis is the main pathway of lung cancer metastasis. The immune status of lymph nodes may be the main factor of lung cancer metastasis. Now on the lung cancer lymph node drainage area to do a review of the immune status.
