Abstract
ObjectiveTo investigate the effect of abdominal breathing training in breast cancer radiotherapy after deep inspiratory breath holding(DIBH).
MethodsAccording to the technical characteristics and clinical requirements of DIBH radiotherapy, a video assisted abdominal DIBH (VAA-DIBH) breathing training method is designed. Breast cancer patients who received radiotherapy in this hospital from November 2019 to September 2020 were randomly divided into conventional group (n=16) and VAA-DIBH group (n=14) according to the inclusion conditions.Age and Vtan volume base values of bilateral pulmonary hearts and hearts in tangent line in CT images under free breath (FB) of patients in the two groups were analyzed.Routine and VAA-DIBH methods were used to intervene in the two groups before repositioning CT scanning, respectively, and the changes of each index volume in the conventional group and VAA-DIBH group on CT images were compared under FB and DIBH.T test was used to compare the mean difference of each volume index between groups.
ResultsThere were 30 patients in the conventional group and VAA-DIBH group.The average age of the two groups was (50.81±12.51) and (51.14±9.23)years (P>0.05), and the difference was not statistically significant(P>0.05). In FB mode, the volume values of left lung, right lung, heart and heart's Vtan in the two groups was not statistically significant (P>0.05). In DIBH mode, except that the volume of right lung in routine group was lower than that in VAA-DIBH group, the difference was statistically significant (P<0.05), and there was no significant difference in other values (P>0.05). In the comparison of volume change and percentage change, except for the heart (P=0.959、0.782), value of the left lung, right lung and heart's Vtan the conventional group were less than those in the VAA-DIBH group and the difference was statistically significant (P<0.05).
ConclusionsVAA-DIBH breathing training method effectively reduces the exposure volume of the organs at risk in breast cancer patients, and improves the stability of patients undergoing DIBH.
