20年前已确认肿瘤的区域淋巴结引流对癌肿病人的重要性。本世纪初外科医生强调另一研究的结果,即1968年声称的“恶性肿瘤手术不是器官手术,而是淋巴系统的解剖”,强调切除肿瘤引流的淋巴组织。当时认为肿瘤淋巴结引流的作用是播散肿瘤细胞的屏障。因此,术中切除肿瘤的淋巴引流组织是合理和必需的。癌细胞离心播散的生物学概念,经50多年的手术实践形成了根治手术治疗的基础。然而新近的观察对这一概念发生怀疑,如在某些恶性肿瘤,切除与不切除淋巴结的总存活率无区别。因为隐(?)性微小 Twenty years ago, the importance of regional lymph node drainage for cancer patients was confirmed. At the beginning of this century, the surgeon emphasized the results of another study. In 1968, he claimed that “malignant tumor surgery is not an organ surgery but an anatomy of the lymphatic system.” It emphasizes the removal of tumor-discharged lymphoid tissue. At that time, it was thought that the role of tumor lymph node drainage was to spread the barrier of tumor cells. Therefore, it is reasonable and necessary to remove the lymphatic drainage tissue of the tumor during operation. The biological concept of the centrifugal dissemination of cancer cells has formed the basis for radical surgery after more than 50 years of surgical practice. However, recent observations have raised doubts about this concept. For example, in certain malignancies, there is no difference in the overall survival rate of resected and unresected lymph nodes. Because the hidden (?)
