73例贲门癌淋巴结转移资料分析

摘要

Objective To explore the rules of lymph node metastasis of the cardiac carcinoma.Methods To review the data of 73 cases suffered cardiac carcinoma that all had been operated.According to the AJCC staging stardards (2009)of stomach cancer.Counting the numbers of lymph nodes examined by pathology.The lymph node metastatic rates (LNMR)and degree of lymph node metastasis in different stage were counted.Results The degree and LNMR of lymph node metastasis of cardiac carcinoma on stage ⅠB was 0% (5 cases);Ⅱa stage was 2.4% and 26.3%.Ⅱb stage 20% and 91.7%;Ⅲa stage 35.9% and 100%;Ⅲb stage 56.8% and 85.7%;Ⅲc stage 51.2%and 100%;Ⅳ stage 78.3% and 100%.There was no difference in the LNMR among the same depth and different length.There was obvious difference in the LNMR among the different depth.The LNMR of mature cardiac cancer was 36.4% and immaturewas 76.6% (P<0.05). Conclusion There is original rule in the lymph node metastases of the cardiac carcinoma.The cardiac carcinoma should be researched as a independent disease.The length of cancer is not important factor in lymph node metastasis but the depth and degree of carcinoma differentia-tion obviously effect the lymph node metastasis.%目的：探讨贲门癌淋巴结转移规律。方法回顾分析一组单纯手术切除、资料完整的73例贲门癌患者，对术后病理检验的淋巴结进行分析统计，计算出不同期别贲门癌淋巴结转移率、转移度。结果淋巴结的转移度、转移率Ⅱa期分别为2．4％和26．3％；Ⅱb期为20％和91．7％；Ⅲa期为35．9％和100％；Ⅲb期为56．8％和85．7％；Ⅲc期为51．2％和100％；Ⅳ期为78．3％和100％；Ⅰb期无淋巴结转移。相同浸润深度而长度不同的淋巴结转移率差异无统计学意义（P＞0．05）。而浸润深度不同则淋巴结转移率存在明显差异。高分化癌淋巴结转移率36．4％，低分化癌则为76．6％（P＜0．05）。结论贲门癌淋巴结转移有其自身规律。病变长度对淋巴结转移的影响不明显，肿瘤的浸润深度和分化程度是影响淋巴结转移的重要因素。
