ANALYSIS OF DOSE AT 3D-CRT AND IMRT TECHNIQUES IN LEFT BREAST CANCER CASE WITH HYPOFRACTIONATION USING DEEP INSPIRATION BREATH-HOLD (DIBH)

---

In terms of breast cancer radiation treatment, it has radiation using the 3D-Conformal Radiotherapy (3D-CRT)
technique and the continuation of the 3D-CRT technique, namely the Intensity Modulated Radiation Therapy
(IMRT) technique. This study aims to evaluate the dosage aspects of PTV and OAR between the 3D-CRT and
IMRT techniques in cases of left breast cancer with hypofractionation using the Deep Inspiration Breath Hold
(DIBH) method using the Conformity Index (CI) and Homogeneity Index (H.I.) and H.I. organ at risk uses
tolerance limits.
This type of research is comparative quantitative with ten samples with primary data conducted at Siloam T.B.
Hospital. Simatupang from November 2019 to April 2020. The research was carried out in the form of radiation
planning with 3D-CRT techniques and IMRT techniques, and the results of planning both techniques were
evaluated between 3D-CRT techniques and IMRT techniques through PTV evaluations using CI and H.I.
values. Furthermore, the organs at risk use tolerance limits on each organ.
The results showed the assessment between 3D-CRT and IMRT on PTV and organs at risk received different
doses. The PTV shows the CI value, which is almost the same as the difference of 0.034, and there is a slight
difference in H.I. with an average value in the IMRT technique of 0.07 and 3D-CRT of 0.11, and it can be seen
that the IMRT is slightly superior because the excellent H.I. value is the closest to 0. Then at the dose of organ
at risk received by the sample, the 3D-CRT technique is slightly superior by obtaining a lower dose that obtains
the difference in the heart by 0.53%, lung by 3.46%, spinal cord by 6.51 Gy, esophagus at 4.5 Gy, and larynx at
5.18 Gy.
