作者采用模糊数学方法研究了１１４例胃癌组织学表现与胃周淋巴结转移的关系。结果表明：胃癌浸润深度、生长方式、异型性、淋巴管和血管侵犯程度、癌间质淋巴细胞浸润程度、间质胶原纤维反应程度与淋巴结转移密切相关。用以上指标计算出判别值（２．９９９）进行判断，有淋巴结转移的符合率为８０．６％，无淋巴结转移的符合率为６１．９％。作者认为该方法在判断胃癌淋巴结转移方面，尤其对隐性转移和缺乏淋巴结材料的病例具有一定的参考意义。
The authors used fuzzy mathematics to study the relationship between histological features and lymph node metastasis in 114 patients with gastric cancer. The results showed that the depth of invasion, growth pattern, atypicality, lymphatic vessel and vascular invasion, lymphocytic infiltration of cancer interstitial and interstitial collagen fibrosis were closely related to lymph node metastasis. Using the above indicators to calculate the discriminant value (2.999), the coincidence rate with lymph node metastasis was 80.6%, and the coincidence rate without lymph node metastasis was 61.9%. The authors believe that this method has certain reference significance in judging lymph node metastasis of gastric cancer, especially in cases of recessive metastasis and lack of lymph node material.
