采用放射免疫分析法检测胃癌病人血清ＴＮＦ．水平，以２５ｆｍｏｌ／Ｌ为临床界值，４７例中２３例阳性．研究ＴＮＦ。与胃癌分期、病理类型、有无淋巴结、腹腔及肝脏转移、ＣＥＡ及手术的关系，结果显示：ＴＮＦ．在Ⅳ期病人及有腹膜转移者阳性率显著高于Ⅱ～Ⅳ期（Ｐ＜０．０５）；ＣＥＡ阳性组与阴性组的ＴＮＦ．阳性率差异显著（Ｐ＜０．０５）；术后第７天ＴＮＦ。含量显著低于术前（Ｐ＜０．０５）．说明ＴＮＦ．检测对判断胃癌分期及判断有无腹膜转移有参考价值。
Radioimmunoassay was used to detect serum TNF in gastric cancer patients. Level, 25fmol / L for the clinical value, 47 cases were positive in 23 cases. Study TNF. The relationship with gastric cancer staging, pathological type, lymph node, abdominal cavity and liver metastasis, CEA and surgery, results showed: TNF. The positive rate in patients with stage IV and with peritoneal metastasis was significantly higher than that in stage II-IV (P<0.05); TNF was positive in CEA positive and negative groups. The positive rate was significantly different (P<0.05); TNF was postoperative on the 7th day. The content was significantly lower than before surgery (P<0.05). Explain TNF. Detection has a reference value for judging the staging of gastric cancer and judging the presence or absence of peritoneal metastasis.
