Abstract Objective: To observe the effects of vacuum pad combined with breast bracketon set-up errors, efficacy and toxic and side effects of patients with set-up radiotherapy of breast cancer. Methods: The clinical data of 86 patients with breast cancer who underwent radiotherapy from April 2013 to April 2016 were retrospectively analyzed. According to the different Methods of radiotherapy position fixing, the patients were divided into observation group (45 cases) and control group (41 cases).Observation group was given vacuum pad combined with breast bracket for fixation, and control group was only given breast bracket for fixation. The set-up errors and pass rate of set-ups, cardiopulmonary irradiation dose, toxic and side effects of radiotherapy and short-term and long-term efficacy were compared between the two groups. Results: The set-up errors of X-axis and Y-axis in observation group were significantly lower than those in control group, and the pass rate of set-ups was significantly higher than that in control group (85.33% vs 63.90%) (P<0.05). The cardiopulmonary irradiation dose in observation group was significantly lower than that in control group (P<0.05), and the total incidence rate of radiotherapy-related toxic and side effects was significantly lower than that in control group (42.22%vs 78.05%) (P<0.05). There were no statistically significant differences in the short-term efficacy and local recurrence, distant metastasis and survival rate within 3 years between the two groups (P>0.05). Conclusion: Vacuum pad combined with breast bracket for set-up radiotherapy of breast cancer can reduce the set-up errors reduce the cardiopulmonary irradiation dose and toxic and side effects of radiotherapy.
