Fig 14.16: Definitive cervix cancer brachytherapy (IB, IIB proximal). Reporting doses and volumes for five different clinical situations (tumour sizes) and treatment schedules. For cases (a), (b) and (c) brachytherapy is combined with external beam therapy. For cases (d) and (e), brachytherapy alone is applied (d) preop. BT (“IGR”); (e) BT alone (“Manchester”). The same brachytherapy technique is assumed for all cases. For cases (a), (b) and (c), the Treated Volume is defined by the 85 Gy isodose. For cases (d) and (e) the Treated Volume is defined by the 60 and 75 Gy isodoses, respectively. For the five clinical cases, the GTVs are shown together with the 60-75-85-95 Gy isodose curves. On the lower part of the figure, the different isodoses are presented at a larger scale to illustrate the differences in the volume dimensions. (for details see legends of figure 6.28)
