癌引流淋巴结虽无转移,也常肿大,这些肿大的淋巴结,除了淋巴细胞增生以外,常看到一种突出的变化,称为淋巴窦组织细胞增生(sinus histiocytosis,简称“SH”)。二十年来,关于癌引流淋巴结“SH”的研究,对乳癌、胃癌和肠癌等,已有不少报导,均证明高度“SH”者,予后较好。多数作者认为,“SH”是宿主对癌产生抵抗力的一种表现。近年来,有人进一步认为,高度“SH”与宿主抗癌的免疫反应 Although lymphatic metastasis is not metastasized, it is often swollen. These enlarged lymph nodes, in addition to lymphocyte proliferation, often see a prominent change called lymphatic sinus histiocytosis (SH). In the past 20 years, there have been many reports on breast cancer, gastric cancer, and bowel cancer in the study of the cancer-draining lymph node “SH”. These have proved to be highly “SH” and better afterwards. Most authors believe that “SH” is a manifestation of the host’s resistance to cancer. In recent years, it was further believed that the highly “SH” and host immune response to cancer
