all rectum applicators.Simulations in patients 3DCT scan allowed us to evaluate CXRT dose to organs at risk and to the target volume.The comparison of dosimetric indices of EBRT and CXRT treatment delivery for the high risk target volume showed that the CXRT technique delivers higher dose to the target volume for the same dose, or even less for some cases, to the organs at risk.Conclusion: Monte-Carlo simulations are useful to compute accurate dose distributions in 3DCT patient data for the CXRT treatment delivery.Moreover, this comparative study between the EBRT and CXRT techniques confirms the role of CXRT in curative treatment with organ preservation for early rectal cancers.
