Brachytherapy is a method for the treatment of cancer, especially cervical cancer. Intracavitary brachytherapy is done by inserting an applicator into the patient's body. Various types of applicators can be used. This study aims to determine the difference in the distribution of doses between vaginal cylinder and ovoid applicators in brachytherapy cervical cancer. There are 16 radiation dose data at point A right and left. The initial dose is given to patients in the ranges from 6 - 8.5 Gy. Calculation of radiation doses are based on AAPM TG-43 by using the Brachytherapy Planning program and done at point A right and left. The radiation point A dose with both applicators were analyzed using independent t-test. The average dose using an ovoid applicator is 2.596 Gy for point A right and 2.630 Gy for point A left, while with the vaginal cylinder applicator is 1.565 Gy at point A right and 1.564 Gy at point A left. There is a significant difference in the dose received by HR-CTV in terms of point A left by using both types of applicator (sig. = 0.007) and from point A right by using each applicator (sig. = 0.001) with α = 0.05. Ovoid applicators provide a more homogeneous dose in terms of the radiation dose at point A so that it becomes an applicator that is more effective in intracavitary brachytherapy of cervical cancer.
