The captions of Figures 15.4 and 15.5 were incorrect in Chapter 15. The correct captions are given below:

Fig. 15.4 Contouring of the upper external and internal iliac lymph node target. ( a ) At the level just below the bifurcation of the common iliac arteries and veins, the right and left external and internal iliac arteries, veins and lymph nodes are seen medial to the psoas muscles. ( b ) Vessels and lymph nodes are contoured for reference ( aqua ). The CTV ( green ) adds a 0.7 cm margin to vessels and adjacent lymphatic tissue, excluding small bowel and psoas. ( c ) For the lymph node PTV ( red ) adds an additional margin of 0.7. In addition a 2 cm strip of tissue anterior to the sacrum ( arrow ) is added to include the presacrallymph nodes

Fig. 15.5 Contouring of the mid external and internal iliac lymph node target. ( a ) Below the level in Fig. 4 external iliac vessles and nodes are seen anteriorly, internal iliac posteriorly and con. ( b ) Vessels and lymph nodes and lymph node CTV ( green ) are contoured as in Figs. 3–4. ( c ) For the lymph node PTV ( red ) adds an additional margin of 0.7. and a 2 cm strip of tissue anterior to the sacrum as in Fig. 4
