Comparison of breast sequential and simultaneous integrated boost using the biologically effective dose volume histogram (BEDVH)

Table 1 Summary of beam angles used in both the sequential boost (SEQ) and the simultaneous integrated boost (SIB) schemes for the ten studied patients (mean ± SD)

Angle (°)	Medial Tang	Medial Boost	Lateral Boost	Lateral Tang
Left-sided ^a	308 ± 3	348 ± 3	111 ± 8	131 ± 3
Right-sided ^b	53 ± 4	21 ± 11	276 ± 21	229 ± 4

^aGroup of 6 patients with left-sided breast tumor. PTV_boost locations were upper/outer quadrate, central quadrate, and lower/outer quadrate in three, two, and one patient respectively
^bGroup of 4 patients with right-sided breast tumor. PTV_boost locations were upper/outer quadrate, lower/outer quadrate, and upper/inner quadrate in two, one, and one patient respectively
