BACKGROUND Radiation pneumonitis (RP) and organizing pneumonia (OP) are the two main types of lung damage that can occur after lung irradiation. The goal of this study was to evaluate the relationship between RP and OP after irradiation for breast cancer. METHODS Four hundred and twenty-eight patients who underwent radiotherapy for breast cancer were identified. The whole breast was irradiate...
A 43-year-old premenopausal female presented with a multicentric infiltrating lobular carcinoma of the left breast with axillary nodes metastasis. She underwent modified radical mastectomy with axillary lymph node dissection (level I and II) followed by a mixed autologous latissimus dorsi flap reconstruction with the addition of prosthesis. The final pathological analysis revealed a 6 cm invasi...
Background: During breast three fields radiotherapy, the problem is that the divergency of the field interferes with matching the edges. So the matching point of these supraclav and tangential field will suffer from over-dose and under-dose. To prevent these these divergency, a half- block is often applied at supracluv field. Also in some techniques like collimator and couch rotation, corner bl...
We report two cases of bronchiolitis obliterans organizing pneumonia (BOOP) syndrome that developed after postoperative radiation therapy for breast cancer. In both patients, chest radiographs and computed tomography (CT) showed multiple consolidations outside the irradiation fields after several months of tangential radiation therapy. These patients were diagnosed as having radiation-associate...
AIMS New technology - specifically intensity-modulated radiotherapy (IMRT) - is now being applied to breast radiotherapy and a recent dosimetric analysis confirmed the advantages of IMRT over 'wedge-only' plans. Such application to everyday practice raises new issues and here we present the early experience of IMRT-based breast irradiation in a single centre. MATERIALS AND METHODS We present ...
