Breast cancer is second most common cancer in the world in 2008. In Indonesia, breast cancer is the most common cancer. Radiotherapy has an important role in breast cancer therapy but gives significant toxicity mainly heart, lung and can lead secondary contralateral breast cancer. Many techniques are performed to reduce the toxicity. The techniques include 3D conformal technique, field-in-field, and simultaneous integrated boost. These techniques already available in Cipto Mangunkusumo Hospital but the dosimetric comparison among these techniques is not available yet. This study is an retrospective study aimed to compare the dosimetric parameters of conformal technique, field-in-field, and simultaneous integrated boost. The study was performed in RSUPN Cipto Mangunkusumo, Jakarta in three months (2010, November until 2011, January). Target population was early stage breast cancer patients (stage I-II) who already had CT planning. Total sample was 10 patients. We compare the dosimetric parameters of patient irradiation therapy using these three techniques. No difference in terms of dose coverage of PTV V95% tumor on the left breast among the three techniques (969.73 cc vs 944.84 vs 914.24 cc, p = 0953). There is a statistically significant difference in terms of Conformity Index (1.001 vs 1.006 vs 1.010).
