The clinical effect of stereotactic radiation therapy combined with sorafenib in the treatment of primary hepatic cancer / 中国医师进修杂志

ABSTRACT

Objective:To investigate the clinical effect of stereotactic radiation therapy combined with sorafenib in the treatment of primary hepatic cancer (PHC).Methods:Ninety-two PHC patients admitted to Cancer Hospital of China Medical University from January 2017 to May 2018 were selected and divided into the observation group and the control group according to the random number table method, with 46 cases in each group. The control group was treated with stereotactic radiation therapy, and the observation group was treated with sorafenib on the basis of the control group. Clinical efficacy and incidence of adverse reactions in the two groups were compared; the scores of Karnofsky performance scale (KPS) and the levels of serum vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), hypoxia-inducing factor (HIF-1α), soluble interleukin-2 receptor (sIL-2R), transforming growth factor (TGF-β1) and alpha-fetoprotein (AFP) before and after the treatment between the two groups were compared. The overall survival (OS) of patients in both groups was recorded after 36 months of follow-up.Results:The total effective rate in the observation group was higher than that in the control group: 84.78%(39/46) vs. 65.22%(30/46), there was statistical difference ( χ2 = 4.70, P<0.05). After the treatment, the score of KPS in the observation group was higher than that in the control group: (85.06 ± 7.19) scores vs. (71.16 ± 7.08) scores; the levels of VEGF, bFGF, HIF-1α, AFP, TGF-β1, sIL-2R in the observation group were lower than those in the control group: (189.52 ± 31.47) ng/L vs. (235.81 ± 35.45) ng/L, (3.89 ± 0.97) ng/L vs. (6.74 ± 1.85) ng/L, (50.17 ± 6.09) ng/L vs. (53.07 ± 6.28) ng/L, (85.76 ± 14.09) μg/L vs. (131.51 ± 18.74) μg/L, (81.07 ± 12.96) μg/L vs. (106.58 ± 15.07) μg/L, (311.58 ± 74.81) kU/L vs. (405.97 ± 85.74) kU/L, there were statistical differences ( P<0.05). The results of 36 months follow-up showed that the 1-year and 3-year OS in the observation group were higher than those in the control group: 69.57% (32/46) vs. 58.70% (27/46), 43.47% (20/46) vs. 28.26 %(13/46), there were significant differences ( χ2 = 4.78, 3.94, P<0.05). Conclusions:Stereotactic radiation therapy combined with sorafenib can effectively improve the efficacy of PHC patients, reduce the expression of VEGF and bFGF, effectively inhibit tumor growth, but also prolong the survival time of patients, with both safety and high effectiveness, and good use value.
