%X In this study, it was evaluated retrospectively the result of 10 patients with cervical cancer who treated with radiotherapy treatment in Bursa Uluda£¿ University between 2014-2017 years. Four different plans were performed using 6 MV and 15 MV photon energies both for volumetric modulated arc therapy (VMAT) and intensity modulated arc therapy (IMRT) 7 field technique used in the treatment planning. All patient were to receive 50.4 Gy dose from 28 fractions. Our aim to organ at risks(OAR) such as; the rectal, bladder, small intestine, right and left femoral heads also Conformity Index(CI) and Homogeneity Index(HI) and total numbers of monitor units were evaluated. As a result of the comparison, the optimal PTV dose homogeneity, the CI value was better in VMAT 15 MV plans and IMRT 15 MV plans showed the best HI values. Bladder and rectum doses were obtained in VMAT 6 MV technique,small intestine doses in IMRT 15 MV technique. Regarding to all planning techniques, dose distributions were within acceptable limits. VMAT 6 MV technique is superior to other techniques when considering the scattered dose and the risk of secondary cancer. Therefore, considering side effects and double effect, VMAT may be preferred as a treatment technique
