Comparison of Cervical Cancer Radiation in Bladder Organs with 10 MV LINAC Energy Radiotherapy Using 3DCRT and IMRT Techniques at Sanglah Hospital Denpasar

A study has been conducted on comparative analysis of cervical cancer radiation to the bladder organ with 10 MV energy LINAC (Linear Accelerator) radiotherapy using 3DCRT (Three Dimension Conformal Radiotherapy) technique and IMRT (Intensity Modulated Radiation Therapy) at Sanglah Hospital, Denpasar. The techniques were compared by analyzing values ??of HI (Homogeneity Index), CI (Conformity Index) dose distribution in OAR (Organ At Risk), namely bladder. data used are 30 patient photon beam planning a total 5000 cGy. In calculating values, 98%, 50%, 2% target volume 95% PTV average Bladder organs. was obtained from DVH (Dose Volume Histogram) statistics contained TPS (Treatment Planning System). results value 0.0818 for 0.0899 statistical test Asimp.Sig (2-tailed) 0.056> 0.05 which means it is not significant, while 0.9500 0.9499 0.970> meanwhile percentage an result irradiation techniques, 96% 88%, respectively, results, 0.000 <0.05, significant. Cervical better than because minimizes absorbed OAR, can be seen getting smaller percentage.
