Radiation therapy is used to treat and control advanced ovarian cancer with spread to abdominal peritoneum. In this study, a comparison between various plans of radiation therapy within the abdomen and pelvis was performed in order to achieve an effective treatment response. Methods: Contouring and planning of 20 patients with CT-scan of the abdomen and pelvis were done by TiGRT software. In order to compare the different types of treatment planning for the selected site, some common criteria

Findings: Among these methods, it was found that the two methods of anterior-posterior and lateral with 18 MV energy and same weight have same level of protection of organs at risk. While the tangent method do not produce a reasonable result. Moreover in anterior- posterior method can be shown that the changing in energy and beam weight give a various results from PTV covering and dose uniformity aspects. Conclusion: Among the various treatment planning were seen that AP/PA with AP = 6MV energy and weight 1, PA = 18 MV and weight 1.5, for covering whole abdomen give a better results.
