ObjectiveTo investigate the feasibility of intra-operative radiation therapy (IORT) in hepato-cellular carcinoma (HCC).MethodsBased on the dosage distribution of tumor and adjacent sensitive organs, and dose-volume histogram (DVH), Topslane three-dimensional therapy plan was used to compare IORT and three-dimensional conformal radiation therapy (3D-CRT) in 12 cases of HCC.ResultsTaking the center of tumors as the isodose center, the V90 (volume of 90% dose distribution) of IORT was significantly better than that of 3D-CRT, and median absorbed doses of normal organs in IORT was significantly lower than that in 3D-CRT.ConclusionThe V90 of IORT is better than that of 3D-CRT in HCC, and neighboring sensitive organs were effectively protected by IORT. The tumors absorbed dose and local control rate are improved in IORT.
