Effect of intensiti modulated radiation therapy according to equivalent uniform dose optimization method on patients with lung cancer

摘要

Objective:To analyze the effect of the intensity modulated radiation therapy according to equivalent uniform dose optimization method on patients with lung cancer.Methods:A total of 82 cases of non-small cell lung cancer were divided into observation group and control group according to the random number table method. Patients in the control group received conventional radiotherapy while observation group received intensity modulated radiotherapy based on equivalent uniform dose optimization method. The treatment effects, survival times, blood vessel-related factors, blood coagulation function and the levels of inflammatory factors and so on were compared between the two groups of patients.Results:The effective rate of the observation group after treatment was higher than that of the control group. Progression free survival and median overall survival times were longer than those of patients in the control group (P<0.05). The serum VEGF and HIF-αα levels as well as D-D, TT, PT, APTT and FIB levels were lower in observation group patients after treatment than those in the control group(P<0.05). At the same time point, serum TNF-αα, CRP and PCT levels in the observation group after treatment were lower than those in the control group (P<0.05). Serum M2-PK, CA125, CEA and SCC values of patients in the observation group after treatment were all significantly lower than those in the control group (P< 0.05).Conclusions:Intensity modulated radiation therapy based on equivalent uniform dose optimized method can improve the treatment effect, prolong the survival time, optimize micro inflammatory environment and inhibit tumor biological behavior at the same time.
