Abstract

The aim of the study was to establish an objective method for evaluation the extent, topography and quantity of skin and soft tissue side effects after tele- and/or brachyradiotherapy of the conserved breast and to compare the sequales of different radiation methods. 26 patients operated on for T1-2 N0-1 breast cancer underwent the following kinds of postoperative radiotherapy: 1. 46-50 Gy whole breast teletherapy + 10-16 Gy electron boost (5 patients), 2. 46-50 Gy teletherapy + 10-15 Gy HDR brachytherapy boost (12 patients), 3. 46-50 Gy teletherapy (6 patients), 4. 36,4 Gy sole HDR brachytherapy of the tumour bed (5 patients). The postirradiation side effects were examined by MRI, mammogram, US and physical examination, as well. MRI was performed on a 0.5 T, double breast coil, with SE-T1, SE-T2 and 3D-GE sequences. The findings of MRI and mammography were compared to physically detectable side effects using the RTOG/EORTC late radiation morbidity scoring scheme. US is useful in the measurement of skin thickening and in the diagnosis of fat necrosis. Mammography and physical examination are very subjective and low specificity methods to evaluate postirradiation side effects. MRI is a suitable and more objective method to detect the real extent and quantity of skin thickening and fibrosis. The incidence of > or = G2 side effects of skin and breast parenchyma were 64.5 and 32.2%, respectively. The differences between the side effects of whole breast irradiation and sole brachytherapy of the tumour bed are also clearly demonstrated. Brachytherapy alone is feasible without compromising cosmetic results. The authors established the MRI criteria for categorization the extent and grade of skin thickening and fibrosis (focal vs diffuse, grade 1-4). Breast MRI is an objective tool for assisting to the evaluation of the side effects of postoperative radiotherapy.
