OBJECTIVEThe aim of this study was to show that the optimum dosage can be delivered to the target organs at risk (OAR) by radiotherapy, which becomes more complicated because of technical difficulties arising from irregular, convex, and complex geometrical structure of the target, such as scalp irradiation, and because of situations resulting from the necessity of bolus of the lesion and immobilization as well as the proximity to neighboring critical organs using the VMAT-SIB technique. METHODSFive different VMAT-SIB schemes were designed using the Varian Trilogy IX linear accelerator (Varian Medical Systems) for total scalp irradiation and bilateral neck irradiation. These different VMAT scehemes were compared with respect to a dose volume histogram of obtained data, homogeneity, indices, conformity index, OAR, and doses of target volumes. RESULTSThe patient-designed bolus plan 1 with two isocenters was chosen as the most appropriate plan. Plans 2, 3, 4, and 5 were inappropriate plans because the application of the virtual bolus in plan 2 was difficult, plan 3 with one isocenter was unacceptable with respect to the value of conformity index, plan 4 with three isocenters had a matching field, and plan 5 in which different priority values were used had an increase in OAR doses. CONCLUSIONVMAT-SIB can be preferred as an appropriate radiotherapy technique as it can provide optimum and allowable OAR doses in tumors requiring an intensive treatment planning effort.

“…1 Although angiosarcoma is the most common of the pure sarcomas occurring in the breast, it comprises < 1% of all breast malignancies, and only a few reports describing FNA cytology of this neo- The degree of tumor differentiation appears to be important in predicting the prognosis of this malignancy. Classification of angiosarcoma into prognostic categories relies mainly on the following histologic features: complexity of pattern, presence of a solid zone, and increased mitoses and necrosis.…”
