The authors and the publisher regret two typing errors on page 194.

In the second column, first bullet point, the correct text should be (indicated in italics):

  • after conventional WBI (25 fractions of 2 Gy) followed by a tumor bed boost of 10 Gy (5 fractions of 2 Gy), the 2 Gy per fraction equivalent dose (2 Gy ED) in the boost area is 60 Gy, and after a booster dose of 16 Gy (8 fractions of 2 Gy), the 2 Gy ED amounts to 66 Gy, respectively. Correspondingly, single doses of 1.8 Gy for WBI and boost up to a total tumor bed dose of 66.6 Gy result in a 2 Gy ED of 63.9 Gy.

In the third column, second paragraph, the typesetting error pre195sent should be corrected to present.
