本文对27例癌组织中(食管癌11例贲门癌16例)脉管癌栓阳性病例的术后标本断端残癌进行了研究。断端残癌发生率(25.9%)较对照组(8.9%)明显高(P<0.05)。有脉管癌栓形成的癌组织恶性程度高,浸润范围广,残癌发生率高。对癌组织中癌栓形成与淋巴结转移的关系及其对预后的影响进行了探讨。认为淋巴结转移是癌组织脉管癌栓形成的外在表现。对术中发现或可疑有淋巴结转移者,应适当考虑切除长度,以防残癌发生。
In this paper, we investigated the residual cancer in the distal part of cancer specimens from 27 cases of cancer (11 cases of esophageal cancer and 16 cases of cardiac cancer) with vascular cancer embolism. The incidence of stump cancer (25.9%) was significantly higher than that of the control group (8.9%) (P<0.05). Cancer tissues with vascular tumor emboli have a high degree of malignancy, a wide range of infiltration, and a high incidence of residual cancer. The relationship between the formation of cancer thrombus and lymph node metastasis in cancer tissues and its effect on prognosis were discussed. It is considered that lymph node metastasis is an external manifestation of vascular tumor thrombosis in cancer tissues. For those who have found or suspected lymph node metastasis during surgery, the length should be properly considered to prevent the occurrence of residual cancer.
