ABSTRACT: Background: Post-operative breast radiotherapy is used to
reduce recurrence. The aim of this
study was to investigate the outcomes of Deep Inspiration Breath-Hold (DIBH) technique with indigenous breath holding indicator scale in 3DCRT for
breast cancer radiotherapy over Free Breathing (FB) technique. Methods: An observational study conducted at the Department of Radiation
Oncology at National Institute of Cancer Research and Hospital, Dhaka and Square Hospital Limited,
Dhaka, Bangladesh from June 2015 to May 2016. A total of 60 confirmed breast cancer patients who underwent
adjuvant radiotherapy were included. An indigenous reproducible plastic tool (Perspex)
was used as breath holding indicator
scale with DIBH technique in 3DCRT. Paired
sample t-test was used to compare with FB technique. Results: The mean age of patients was 47.32 (SD ± 8.33) years. In FB technique, Mean Heart Dose
(MHD) was 413.27 cGy while in DIBH technique, it was 254.91 cGy (P and V30 were 5.5%, 4.37% in FB and 3.13%, 2.36% in DIBH
respectively. In FB technique LADMD, LAD 0.2 cm3, ILMD and ILV20 were 1698.17 cGy, 2852.53 cGy, 1155.31
cGy and 28.62% while in DIBH technique, it was reduced to 1164.01 cGy,
2132.24 cGy, 1007.98 cGy and 23.39% respectively. Similarly, the lung-CLMD and
breast-CLMD were reduced
from 38.37 cGy and 55.18 cGy to 24.64 cGy and 33.82 cGy respectively (P Conclusion: The use
of indigenous breath holding indicator
scale with DIBH had better outcomes on breast cancer radiotherapy.
