Abstract
Objective: To investigate the effect of different doses of stereotactic radiotherapy (SBRT) on the recurrence, metastasis and survival of lung cancer patients. Methods: The clinical data of 13 patients with lung cancer who were treated in our hospital from May 2016 to June 2020 and were followed up for one year were retrospectively analyzed. The patients treated with low-dose SBRT were divided into the observation group (7 cases) and the patients treated with high-dose SBRT were divided into the control group (6 cases). The clinical efficacy, recurrence, metastasis, survival status and incidence of adverse reactions were compared between the two groups. Results: There were no significant differences in the clinical total effective rate, 1-year recurrence rate, metastasis rate and survival rate between the two groups (P>0.05); The incidence of adverse reactions in the observation group was lower than that in the control group, the difference was statistically significant (P<0.05). Conclusion: High dose or low dose SBRT can achieve good curative effect and prognosis in patients with lung cancer, but low dose SBRT has less adverse reactions and higher safety.
