Abstract:
Objective:To investigate the efficacy and safety of camrelizumab combined with stereotactic body radiation therapy (SBRT) in the treatment of advanced oligometastaticnon-small cell lung cancer (NSCLC).Methods:Eighty-six patients with advanced oligometastatic NSCLC who met the inclusion and exclusion criteria from March 2020 to August 2021 in the Second People′s Hospital of Yibin were divided into the control group (43 cases) and the treatment group (43 cases) according to the random number table method, the control group was given camrelizumab combined with conventional radiotherapy, and the treatment group was given camrelizumab combined with SBRT. After 8 weeks of treatment, the efficacy of the two groups was evaluated, the occurrence of side effects in the two groups was counted, the serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment anti-21-1 (CYFRA21-1)] levels were detected.Results:The objective effective rate of the treatment group was significantly higher than that of the control group:: 72.09% (31/43) vs. 51.16%(22/43), the difference was statistically significant ( P<0.05); the incidence of radiation pneumonia in the treatment group was significantly lower than that in the control group: 4.65% (2/43) vs. 18.60% (8/43), the difference was statistically significant ( P<0.05), and there was no significant difference in the incidences of other side effects such as cutaneous capillary endothelial proliferation (CCEP), liver damage, hypothyroidism, and radiation esophagitisbetween the treatment group and the control group ( P>0.05); the levels of serum CEA, SCC-Ag, CYFRA21-1after treatmentin the two groups were significantly lower than those before treatment, treatment group: treatmentgroup: (8.81 ± 4.82) ng/L vs. (81.67 ± 50.88) ng/L, (1.13 ± 0.55) ng/L vs. (1.56 ± 1.03) ng/L and (2.92 ± 0.99) ng/L vs. (4.63 ± 1.39) ng/L, controlgroup: (30.49 ± 19.44) ng/L vs. (89.91 ± 50.10) ng/L, (1.56 ± 1.23) ng/L vs. (1.86 ± 1.33) ng/L and (4.01 ± 2.10) ng/L vs. (5.03 ± 3.44) ng/L. and the levels after treatment in the treatment group were significantly lower than those in the control group, and there were statistical differences ( P<0.05). Conclusions:Camrelizumab combined with SBRT treatment for patients with advanced oligometastatic NSCLC can effectively reduce the levels of serum CEA, SCC-Ag, CYFRA21-1, and significantly improve the short-term efficacy, with relatively low incidence of toxic side effects.
