Abstract:【Objective】 To analysis effect of endoscopic tumor augmentation combined with deep thermal therapy on advanced gastric cancer patient’s survival condition and immune function levels. 【Methods】 The patients with advanced gastric cancer in our hospital were choosed as research object, randomly divided into control group with pure shrinkage tumor treatment, and observation group with endoscopic tumor augmentation combined deep thermal therapy. The survival condition, tumor area, hemoglobin levels and immune function in two groups were compared. 【Results】 One and two year survival rate in observation group were higher than that in control group, average survival time was longer than control group (P <0.05). The tumor size in observation group after treatment were significantly less than that in control group. Hemoglobin level were significantly higher (P <0.05). The CD4+, CD4+/CD8+ levels in observation group after treatment were higher than that in control group, and CD8+ levels in observation group were lower (P <0.05). 【Conclusion】 Endoscopic tumor augmentation combined deep heat treatment can significantly reduce tumor size and hemoglobin levels in patients with ascension, optimization of the whole body immune function, prolong patient survival time.
